Detailed Description

The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

A method of machining a shaped shoe, a shaped shoe and a compressor provided according to some embodiments of the present invention are described below with reference to fig. 1 to 6. In particular, the shaped shoe machining method is for making shaped shoes, it being understood that the shaped shoes may be thrust shoes of a compressor, i.e. the shaped shoes may be applied to a compressor, for example, carbon dioxide compressors and syngas compressors. Furthermore, the compressor comprises a thrust bearing, and a plurality of special-shaped pads are fixedly connected with the annular surface of a fixed ring of the thrust bearing, namely the special-shaped pads are parts of the thrust bearing. In the processing method of the special-shaped tile in the related technology, the pin is usually assembled on the end face of the special-shaped tile by a punching method, the working face of the tile is deformed by the processing method, namely, the flatness of the working face of the tile is influenced, and the working performance of the compressor is influenced because the manufacturing precision of the working face of the tile is directly related to the tile temperature, namely, the flatness of the working face of the tile is lower, the tile temperature is higher, and the high temperature of the tile can cause the load reduction operation of the compressor.

In view of the above, an embodiment of the first aspect of the present invention provides a method for processing a special-shaped tile, as shown in fig. 1, the method comprising:

step 102: sequentially adsorbing the tile primary products assembled with the pins to the magnetic sucking discs;

step 104: and turning the primary tile product, and removing the deformation of the working surface of the primary tile product to obtain a finished tile product.

The method for processing the special-shaped tile provided by the embodiment of the invention sequentially absorbs the tile primary product 110 assembled with the pin 120 to the magnetic chuck 130, namely, the tile assembled with the pin 120 by a dead punch method in the related art is placed on the magnetic chuck 130 and is absorbed by the magnetic chuck 130, namely, the tile processed in the related art is defined as the tile primary product 110 of the invention, the tile primary product 110 is fixed to the magnetic chuck 130, then, the turning processing is carried out on the tile primary product 110, the deformation of the working surface 112 of the tile primary product 110 is removed, so as to manufacture a finished tile product, therefore, the planeness of the working surface 112 of the finished tile product is greatly improved, the processing precision of the working surface 112 of the finished tile product is improved, the improvement of the temperature of the tile in the running process of the compressor is facilitated, and the condition of the reduced load running of the compressor caused by the higher temperature of the tile is reduced, greatly improves the working performance of the compressor and is suitable for popularization and application. That is, the invention adds a step of turning deformation to the finished tile in the related technology, thereby greatly improving the manufacturing precision of the working surface 112 of the finished tile, reducing the influence on the working performance of the compressor, avoiding a series of problems caused by overhigh temperature of the thrust tile in the trial run process of the compressor unit, for example, solving the problem of unqualified trial run caused by the processing deformation of the thrust tile, being beneficial to reducing the trial run cost of the compressor type product, and being suitable for popularization and application.

In some possible implementation embodiments provided by the present invention, before step 102, the method for processing a special-shaped tile further includes:

step 101-1: turning the blank to form a disc;

step 101-2: milling the disc to form a plurality of tile matrixes;

step 101-3: milling a pin groove on any tile base body;

step 101-4: the pin 120 is placed in the pin slot and the pin is punched to death to make a primary tile.

In this embodiment, a process of making a tile precursor 110 from a blank is described. The method comprises the steps of firstly turning a blank to form a disc, and milling the disc to form a plurality of pad matrixes as the special-shaped pads are part of the approximate fan-shaped structure. Next, milling a pin groove 111 on any tile substrate, placing the pin 120 in the pin groove 111, and fixing the pin 120 to the tile substrate by punching to form the tile primary 110. It will be appreciated that the amount of deformation of the working surface 112 of the pad precursor 110 is due to the assembly of the pin 120 to the pad substrate, such as by fixing the pin 120 to the pad substrate by punching.

In some possible embodiments provided by the present invention, as shown in fig. 2 and 3, the magnetic chuck 130 comprises a disc body 131 and a first wrench 133, the disc body 131 is provided with a plurality of groove structures 132 distributed in a circle, wherein the number of the groove structures 132 is the same as that of the tile precursors 110, and it can be understood that the distribution pattern of the groove structures 132 on the disc body 131 is similar to that of the tile bases on the disc. The first wrench 133 is detachably connected to the tray 131, that is, the tray 131 is provided with an insertion hole 135 or a connection structure adapted to the first wrench 133, and the first wrench 133 can be connected to the tray 131 through the insertion hole 135 or the connection structure as required, and when the first wrench 133 is connected to the tray 131, the first wrench 133 can rotate relative to the tray 131 to make the tray 131 have magnetic force or lose magnetic force, that is, the first wrench 133 is a monkey wrench and can control whether the tray 131 has magnetic force. When the first wrench 133 is not needed, if the disc body 131 has magnetic force after the first wrench 133 is rotated, the first tile 110 is already attached to the disc body 131, at this time, the first wrench 133 can be pulled out from the insertion hole 135 or the connection structure to be separated from the disc body 131, so that the first tile 110 on the disc body 131 can be conveniently turned, and the first wrench 133 is prevented from being connected with the disc body 131 to interfere with machining. It can be understood that, after the deformation of the working surface 112 of the primary pad 110 is removed and the finished pad is manufactured, the first wrench 133 may be connected to the disc 131 through the insertion hole 135 or the connection structure, and the first wrench 133 is rotated to make the disc 131 lose magnetic force, so that the finished pad is conveniently taken off from the disc 131, which is simple in operation and convenient in use.

Specifically, as shown in fig. 3, when the first wrench 133 is connected to the disc 131 through the insertion hole 135 and the first wrench 133 is located at the position a, the disc 131 has no magnetic force, i.e., the magnetic suction cup 130 is in the closed state, and at this time, the first wrench 133 is rotated, and when the first wrench 133 is located at the position B, the disc 131 has magnetic force, i.e., the magnetic suction cup 130 is in the working state. It can be understood that when the first wrench 133 is located at any one of the position a and the position B, the first wrench 133 can be pulled out from the insertion hole 135, which facilitates the operation.

In this embodiment, further, step 102 specifically includes:

step 102-1: placing any tile primary product in any groove structure, wherein one end of the tile primary product, which is provided with the pin, is an assembly end face, the assembly end face is in contact with the groove top of the groove structure, and the pin is positioned in the groove structure;

step 102-2: when all the tile primary products are placed in the groove structure, the first wrench is rotated to enable the tray body to have magnetic force so as to adsorb the tile primary products on the tray body.

That is, after placing a tile primary 110 in one groove structure 132 and repeating the above operations, after placing all the tile primary 110 in all the groove structures 132, the first wrench 133 is rotated to make the disc body 131 have magnetic force, so that all the tile primary 110 can be attracted to the disc body 131, i.e., all the tile primary 110 are fixed to the disc body 131.

The back surface of the pin 120 is of an arc structure, that is, the end of the pin 120 protruding from the assembling end surface 113 is of a curved structure 121, so that the pin is inconvenient to clamp and adsorb for turning, milling or grinding, and the processing and manufacturing are difficult. Therefore, the invention defines that one end of the tile primary product 110, which is provided with the pin 120, is the assembly end surface 113, the assembly end surface 113 of the tile primary product 110 is in contact with the top of the groove structure 132, and the pin 120 is located inside the groove structure 132, that is, the invention uses the groove structure 132 to avoid the position of the pin 120 on the tile primary product 110, so that the curved surface structure 121 of the pin 120 is located in the groove structure 132 and is not in contact with the adsorption surface of the disc body 131, and the tile primary product 110 near the pin 120 is in contact with the top of the groove structure 132, thereby meeting the flatness of the tile primary product 110 after adsorption, further being beneficial to improving the processing precision of removing the deformation of the working surface 112 of the tile primary product 110, and greatly improving the flatness of the working surface 112 of the finished tile product.

Further, as shown in fig. 3, 4, 5 and 6, the pad base includes at least one processing position for punching the pin 120, and basically, in the processing position, the pin 120 can be fixed to the pad base to form the primary pad 110 by using a punching method, and it can be understood that a part of the position of the mounting end surface 113 of the primary pad 110 opposite to the processing position is defined as a punch dead point 114. Therefore, when any tile primary product 110 is placed in any groove structure 132, the part of the assembly end surface 113 of the tile primary product 110 corresponding to the processing position is located inside the groove structure 132, i.e. the punch dead point 114 on the assembly end surface 113 of the tile primary product 110 is not in contact with the groove top of the groove structure 132, i.e. the position of the punch dead point 114 on the assembly end surface 113 of the tile primary product 110 is not an adsorption surface, i.e. the groove structure 132 of the magnetic chuck 130 can avoid the punch dead point 114 on the assembly end surface 113 of the tile primary product 110, so as to ensure that the tile primary product 110 after being attached has higher flatness, thereby being beneficial to improving the processing precision of the deformation of the working surface 112 of the tile primary product 110, and greatly improving the flatness of the working surface 112 of the finished tile product.

It can be understood that, as shown in fig. 4 and fig. 6, the number of punch dead points 114 is plural, and the plural punch dead points 114 can be distributed on the assembling end surface 113 of the tile primary 110, and also can be distributed on the periphery of the tile primary 110, and different positions of the punch dead points 114 can satisfy the requirement that the pins 120 are punched on the tile base body from different directions to form the tile primary 110, specifically, in some possible embodiments provided by the present invention, the number of punch dead points 114 is six, four of the punch dead points are distributed on the assembling end surface 113 of the tile primary 110, and the other two punch dead points are distributed on the periphery of the tile primary 110.

In some possible embodiments, the magnetic chuck 130 further comprises a ring pad detachably connected to the disk body 131, the disk body 131 is provided with a raised structure along the circumferential side, the raised structure is located at the side of the disk body 131 provided with the groove structure 132, i.e., the raised structure corresponds to the outer edge of the disc 131, during the process of machining the shaped pad, after the step of placing all pad precursors 110 in the groove structures 132, prior to the step of rotating the first wrench 133, by capturing an annular pad between the outer diameter of the tile precursor 110 and the raised formation, so as to limit the movement of the initial tile 110 along the radial direction, and prevent the initial tile 110 from turning, during the rotation of the disc body 131, the position of the tile primary 110 is deviated, further, the machining accuracy of the deformation amount of the working surface 112 of the initial tile 110 to be removed is improved. It will be appreciated that during the turning of the green insert 110 to form the finished insert, the magnetic chuck 130 is clamped to a lathe, such as a horizontal lathe, and is capable of rotating relative to the lathe tool to effect the turning operation that removes the amount of deformation of the working surface 112 of the green insert 110.

Specifically, the annular pad is the elastic component, and the elastic component card is established between the outer diameter of the first article of the tile 110 and the protruding structure of disk body 131, is favorable to improving the reliability that the first article of the tile 110 is connected with disk body 131, further ensures that disk body 131 is at rotatory in-process, perhaps carries out lathe work's in-process to the first article of the tile 110, and the condition of position skew can not appear in the first article of the tile 110, promotes the off-the-shelf working face 112's of tile plane degree greatly.

In some possible embodiments of the present invention, as shown in fig. 3, the magnetic chuck 130 further comprises a second wrench 134 detachably connected to the plate 131, i.e. the second wrench 134 can be connected to or separated from the plate 131 as required. When the second wrench 134 is connected with the tray 131, at least a part of the second wrench 134 is located outside the tray 131 along the radial direction of the tray 131, so that the second wrench 134 can be used as an auxiliary support in the process of carrying the tray 131 or fixing the tray 131, that is, an operator can carry the magnetic chuck 130 to a proper position by holding the second wrench 134 with hands, the operation is simple, and when the magnetic chuck 130 is carried to a proper position, the second wrench 134 can be pulled out of the tray 131, so that the use is convenient. It can be understood that the tray 131 is provided with an insertion opening 136 adapted to the second wrench 134, so as to facilitate the second wrench 134 to be inserted into the insertion opening 136 and connected with the tray 131, or to be pulled out from the insertion opening 136 and separated from the tray 131. Specifically, the number of the insertion ports 136 may be one, two or more, and the number of the second wrench 134 may be one, two or more, and the present invention is not particularly limited.

In some possible implementation embodiments provided by the present invention, step 104 specifically includes:

turning the end face of the primary tile far away from the magnetic chuck;

wherein the turning amount ranges from 0.03mm to 0.07mm to remove the deformation amount of the working surface of the primary tile.

In this embodiment, the end surface of the initial tile 110 away from the magnetic chuck 130 is turned, that is, after the initial tile 110 is attached to the magnetic chuck 130, the end of the initial tile 110 away from the magnetic chuck 130 is a working surface 112, and the pin 120 is installed on the other end surface opposite to the working surface 112, that is, the assembling end surface 113 of the initial tile 110 contacts with the magnetic chuck 130 for attachment. It will be appreciated that the amount of deformation of the working surface 112 of the pad precursor 110 is due to the assembly of the pin 120 to the pad substrate, such as by fixing the pin 120 to the pad substrate by punching. Therefore, the end face of the first tile 110, on which the pin 120 is mounted, is attracted to the magnetic chuck 130, and the end face of the tile, which is far away from the magnetic chuck 130, is turned, so that the turning of the tile working face 112 can be realized, and the operation is simple. And, because the deformation of the working face 112 product will not be great in the process of assembling the pin 120 to the tile, therefore, the range of controlling the turning amount is 0.03mm to 0.07mm, the deformation of the working face 112 of the initial tile 110 can be removed, so that the flatness of the working face 112 of the finished tile reaches the manufacturing and processing requirements, the manufacturing precision of the working face 112 of the finished tile is greatly improved, the influence of the processing precision of the working face 112 of the finished tile on the tile temperature is reduced, and the working performance of the compressor is favorably improved. In particular, the amount of turning may be 0.03mm, 0.05mm, 0.07mm or other values that meet the requirements.

Embodiments of the second aspect of the present invention provide a shaped tile produced by the method of processing a shaped tile according to any of the embodiments of the first aspect. Since the special-shaped tile is manufactured by the special-shaped tile processing method of any embodiment of the first aspect, all technical effects of any embodiment of the first aspect are achieved, and no further description is given here.

An embodiment of a third aspect of the present invention provides a compressor, including: the shaped pad of any embodiment of the second aspect. Since the compressor includes the special-shaped pad of any embodiment of the second aspect, the technical effects of the embodiment of the second aspect are all achieved, and are not described in detail herein.

Further, the compressor also comprises a thrust bearing, the thrust bearing comprises a fixed ring and special-shaped pads, and the special-shaped pads are fixedly connected with the ring surface of the fixed ring. Namely, the special-shaped pad is a part for forming the thrust bearing of the compressor. Specifically, the compressors are a carbon dioxide compressor and a synthesis gas compressor.

According to the method for processing the special-shaped tiles, after the execution of the original process scheme is finished, namely after the tiles are punched to be dead with the pins 120, a group of tiles (namely the primary tiles 110) are uniformly distributed in the groove structures 132 of the disc body 131 of the magnetic chuck 130, magnetic force is started and the annular pads are used for assisting in fixing, the tiles (namely the primary tiles 110) are adsorbed onto the disc body 131, the working face 112 of the primary tiles 110 is processed, 0.05mm of deformation is removed in a processing mode, and the flatness of the working face 112 of the thrust tiles (namely the finished tiles) is improved.

Further, after the tile primary product 110 is manufactured, the tile primary product is approximately of a fan-shaped structure with an angle, and one end of the assembled pin 120, which is far away from the working surface 112 of the tile primary product 110, is of an arc structure or a curved surface structure 121, so that turning, milling or grinding or clamping or adsorption cannot be performed, and great difficulty is brought to the manufacturing and processing, therefore, the invention provides a new manufacturing and processing method, and the magnetic suction cup 130 with the groove structure 132 assists in the processing of the special-shaped tile.

Specifically, the groove structure 132 of the magnetic chuck 130 is required to satisfy the requirement of avoiding the positions of the pin 120 and punch dead point 114 of the shoe precursor 110, namely, the pin 120 of the initial tile 110 and the punch dead point 114 on the assembling end surface 113 are not adsorbed on the disc body 131, so that the flatness of the adsorbed initial tile 110 can be satisfied, meanwhile, the magnetic chuck 130 is additionally provided with an auxiliary annular pad for fixing the plurality of tile initial products 110 which are uniformly distributed, so that the magnetic chuck 130 is prevented from rotating, the tile precursor 110 is misaligned such that, after the original process recipe is completed, a group of tiles can be uniformly distributed in the groove structure 132 of the magnetic chuck 130, the magnetic force is turned on and the annular pad is used for assisting the fixation, the tile primary product 110 is absorbed on the disc body 131, then the deformation of the working surface 112 of the tile primary product 110 is processed, the finished product of the pad, namely the special-shaped pad can be manufactured, and the flatness of the working surface 112 of the finished product of the thrust pad is improved. Meanwhile, the problem that the temperature of the thrust pad of the compressor unit is too high due to the fact that the working face 112 of the manufactured thrust pad is deformed in the related technology is solved, a series of problems caused by the fact that the temperature of the thrust pad is too high in the process of trial run of the compressor unit are further avoided, if the problem that the trial run is unqualified due to the fact that the thrust pad is deformed in machining is solved, and the trial run cost of the compressor type product is reduced. Moreover, the processing method of the special-shaped tile block provides a thought for processing and manufacturing special-shaped pieces of the same type, can solve the problem that a plurality of processing and manufacturing of the same type are chronic, and is suitable for popularization and application.
