When the polishing device is used and needs to polish the conical pipe fitting, firstly, the conical pipe fitting with the same specification is placed in the feeding box 2, then the device is started, the driving motor connected with the central shaft of the rotating rod 5 rotates to drive the rotating rod 5 to rotate, the rotating direction of the rotating rod rotates towards the direction of the arc-shaped protruding part 11, and in the rotating process:

1) the fixed block 51 arranged on the rotating rod 5 also synchronously rotates, then the shifting block 45 arranged on the baffle piece 3 arranged at two sides of the feeding box 2 is shifted, the convex part 511 formed on the fixed block 51 extrudes and penetrates between the shifting block 45 and the baffle piece 3, then in continuous rotation, the convex part 511 can extrude the rolling ball on the shifting block 45, so that the rolling ball drives the baffle piece 3 to rotate outwards along the shaft rod, namely the second bearing column 32 is separated from the borne conical pipe, then the first bearing column 31 at the upper part can draw close to the feeding box 2, then the conical pipe positioned at the upper part is supported, the first bearing columns 31 at two ends are inserted into the pipe holes in the conical pipe to support the conical pipe at the upper part, then the pipe at the lower part falls into the placing groove (the shaft rod rotationally connected with the baffle piece 3 and the feeding box 2 is provided with a torque spring, the elasticity of the torque spring enables the second bearing column 32 arranged at the lower part of the baffle piece 3 to face the feeding box 2, and the upper first support column 31 is far away from the feed box 2 and the stop 3 can rotate relative to the rotation direction of the feed box 2).

2) After the conical part drops to the standing groove, change transmission post 7 that 5 both ends of rod set up through arc bulge 11, under the extrusion of arc bulge 11, transmission post 7 removes to the direction of turning rod 5, make at the in-process that removes, can drive the synchronous inward movement of holder 72 that is connected, at this moment, will carry out the centre gripping to conical pipe spare soon, it is concrete, the big head department cover of conical pipe spare is on the outer wall of the big mouth portion 7201 of holder 72, then the little head department of conical pipe spare pegs graft in little mouth portion 7202, (the radial dimension of holder 72 big mouth department and the radial dimension of little mouth portion 7202 process then at the in-process of the inside extrusion of holder 72 according to the two head dimensions of the conical pipe spare of treating processing: 1. at the big end: the big end of the conical pipe is sleeved on the big opening 7201, then when the conical pipe is extruded by the arc-shaped protrusion 11, the side wall of the conical pipe can abut against the pressing handle 92, then (a friction pad which is arranged on the pressing handle 92 and increases friction force), under the interference of the conical pipe, the pressing handle 92 enables the first extrusion to move towards the direction far away from the first hinge rod 91 under the action of the first hinge rod 91, then as the first extrusion block 439 is in wedge-shaped contact with the clamping piece 72, as shown in fig. 9, the first extrusion block 439 can protrude outwards along the inclined plane, so that the first extrusion block can be in contact with the inner wall of the conical pipe, and the friction force between the clamping piece 72 and the conical pipe can be increased; 2. small end: the small end of the tapered pipe is inserted into the small opening 7202, then when the tapered pipe is pressed by the arc-shaped protrusion 11, the sidewall of the small end of the tapered pipe abuts against the bearing plate 721, and then (the bearing plate 721 is also provided with a friction pad for increasing the friction force with the tapered pipe), under the abutment of the tapered pipe, the bearing plate 721 presses towards the first wedge-shaped block 1003, so that the first wedge-shaped block 1003 moves towards the first elastic member 1002, thereby driving the second hinge rod 1001 to rotate along the shaft hinged with the clamping member 72, and moving the second pressing block 4310 rotationally connected with the second hinge rod 1001 towards the small opening 7202, as shown in fig. 10, thereby increasing the friction force between the clamping member 72 and the tapered pipe;

3) when the conical pipe enters the placing groove and is clamped by the clamping assembly, because the radial sizes of the axial positions of the conical pipe are different, the conical pipe is in contact with the friction plates 4 on the friction assembly arranged in the placing groove, when the conical pipe is placed on the friction assembly, the second elastic piece 42 at the corresponding position is correspondingly extruded, so that the second elastic piece 42 receives different gravity, the elastic deformation of the second elastic piece is in different degrees, the elastic force acts on the pressing block 43, the pressing block 43 abuts against the second wedge-shaped block 44 which is horizontally placed, and due to the different elastic forces of the second elastic piece 42, the elastic force of the second elastic piece 42 overcomes the friction force between the second wedge-shaped block 44 and the rotating rod 5, the second wedge-shaped blocks 44 on each group move outwards by different distances, so that the acting force of each friction plate 4 on the conical piece is basically consistent, therefore, when the rotary grinding is carried out, the grinding force of the surface of the conical pipe fitting is basically consistent, and the grinding uniformity of the surface of the conical pipe fitting is improved.

4) After the conical pipe fitting is clamped, the transmission gear 71 on the transmission column 7 at the moment corresponds to the position of the meshing teeth 6, then, after the continuous rotation, the transmission gear 71 rotates by itself under the meshing action of the meshing teeth 6, namely, the fixedly connected clamping piece 72 is driven to rotate, so that the conical pipe fitting is driven to rotate in the placing groove in the rotating process, then as the friction component in the placing groove is unchanged, during rotation of the conical member, the conical tube is caused to rub against the friction plate 4, i.e., when the conical piece is polished and the transmission post 7 is separated from the arc-shaped bulge part 11, the two clamping pieces 72 return to the initial positions under the elasticity of the tension spring, the clamping of the conical pipe piece is released, then, after the continuous rotation, the polished conical member falls onto the carrier wheel 211 on the first transport base 21 through the through hole at the bottom of the box 1.

In order to facilitate smooth conveying of the tapered pipe after surface treatment to the quenching equipment, a first conveying seat 21 and a second conveying seat 12 are arranged below the box body 1 and used for conveying and reversing the tapered pipe, and since the direction of the tapered pipe processed in the box body 1 is random, when the tapered pipe falls onto a bearing wheel 211 on the first conveying seat 21, the large end of the tapered pipe can be conveyed forwards, which is inconvenient for conveying the tapered pipe to the quenching equipment, so that a reversing device for reversing the tapered pipe is arranged behind the first conveying seat 21 to solve the problem that the large end of the tapered pipe is conveyed forwards.

When the tapered pipe after surface treatment enters the first conveying seat 21, the tapered pipe is continuously conveyed towards the second conveying seat 12 by the conveying bearing wheel 211, during the conveying process, if the small end is conveyed ahead, because the weight of the small end is small compared with that of the large end, when the tapered pipe is conveyed to the position of the conveying belt 15 continuously, the tapered pipe can be conveyed to the conveying belt 15 above the second conveying seat 12 continuously, then the tapered pipe can be conveyed continuously, when the tapered pipe is conveyed to the large end, when the tapered pipe is conveyed to the position of the bearing guide wheel 2111 arranged on the first conveying seat 21 continuously, because the weight of the large end of the tapered pipe is heavy, when the tapered pipe passes through the position of the bearing guide wheel 2111, the two bearing guide wheels 2111 are caused to move outwards in an adaptive manner, as shown in fig. 17, the two bearing guide wheels 2111 will move towards the direction of the rotating column 212 respectively, and at this time the large end will sink a part, then under the conditions of continuous conveying and self-gravity, the big end of the tapered pipe will finally incline and fall onto the conveyor belt 15, as shown in fig. 20, at this time, the big end of the tapered pipe is clamped on the limiting convex column 151 arranged on the conveyor belt 15, then the side wall is lapped on the bearing guide wheel 2111 arranged on the first conveying seat 21, then under the continuous conveying of the conveyor belt 15, the big end of the tapered pipe is driven to move along the conveying direction of the conveyor belt 15, the conveyor belt 15 passes under the first conveying seat 21 and also drives the tapered pipe to move under the end of the first conveying seat 21, at this time, the tapered pipe will be in a vertical state, then when the conveying is continued, the tapered pipe will tilt towards the direction of the second conveying seat 12 with the big end of the tapered pipe as a fulcrum, when the tilting is performed, the tilted state is as shown in fig. 21, at this time, the tilted tapered pipe is placed into the conveying assembly (the initial state of the transmission assembly is as shown in fig. 17, the two guide wheel discs 131 are at the farthest distance, the poured conical pipe can pass through the two guide wheel discs 131 and fall onto the supporting wheel 132, the supporting wheel 132 is at the top, the third elastic element 1321 is not in a compressed state, and the shifting fork 1312 is in an inclined state), and the conveying assembly at this time has the following states:

1) the inclined conical pipe passes through the two guide wheel discs 131 and is then caught by the support wheels 132, and the support wheels 132 are compressed obliquely downward under the gravity of the conical pipe and are compressed downward along the inclined buffer grooves 1303, that is, the support wheels 132 also move obliquely downward in a synchronous manner.

2) In the process of moving downwards, the rollers 1323 arranged on the shaft rods at the two sides of the supporting wheel 132 also move downwards in an inclined manner, because the rollers 1323 are arranged in the transmission grooves 1302 formed in the shifting fork 1312 in a rolling manner, when the rollers 1323 move downwards, the shifting fork 1312 in the inclined state is driven to rotate along the shaft hinged with the connecting shaft sleeve 1313, the other end of the shifting fork 1312 is movably arranged on the sleeve 1311, so that the two guide wheel discs 131 are synchronously driven to move oppositely, the two guide wheel discs 131 are folded, then when the guide wheels 131 are closed, the first contact point 1314 and the second contact point 1315 are contacted, even if the driving motor for driving the guide wheel discs 131 to rotate starts to rotate, and the conical pipe fitting at the moment is arranged between the supporting wheel 132 and the two guide wheel discs 131, (because the conical pipe fitting is obliquely inclined to the supporting wheel 132, therefore, in the invention, the supporting wheel 132 and the spring post 1322 are also obliquely arranged, so that the tilting force of the conical pipe fitting can be directly received, the force dispersion and friction of the device are reduced, the stretching of the third elastic member 1321 is facilitated, the supporting wheel 132 is obliquely glided, meanwhile, the connecting shaft sleeve 1313 is arranged in the arc-shaped groove 1301 in a sliding manner, the shifting fork 1312 is rotationally arranged on the connecting shaft sleeve 1313, the rotating direction of the shifting fork 1312 is perpendicular to the arc-shaped groove 1301, so that the inclined shifting fork 1312 can be pressed when the roller 1323 moves obliquely downwards, the shifting fork 1312 can be driven to move in the rotating process of the rolling ball along the rotating shaft of the connecting shaft sleeve 1313, and the connecting shaft sleeve 1313 is arranged in the arc-shaped groove 1301 in a sliding manner, so that the displacement generated by driving the shifting fork 1312 during oblique depressing can be adapted, that the tilting force of the conical pipe fitting can be directly received, and the shifting of the shift fork 1312 to the guide wheel can be not affected by the arrangement of the connecting bushing 1313).

3) At this time, one end of the tapered pipe is also lapped on the first bearing assembly on the second conveying seat 12, as shown in fig. 21, and then under the rotation of the bearing guide wheel 2111 and the guide wheel disc 131, the tapered pipe is driven to move, that is, the tapered pipe gradually passes through the first bearing assembly on the second conveying seat 12 and then gradually passes through the space between the supporting wheel 132 and the two guide wheel discs 131, and finally is conveyed, so that the tapered pipe is conveyed to the plurality of bearing guide wheels 2111 arranged on the second conveying seat 12, thereby reversing the conveying direction of the tapered pipe, and then is conveyed through the conveying assembly, thereby facilitating the quenching processing of the tapered pipe.
