Detailed Description

The device for assembling the cradle body and the plastic part of the spinning frame comprises a conveying line 62, a workpiece clamp 5, a cradle body feeding mechanism 6, a material part feeding mechanism 7, a transfer mechanism 9 and a press-fitting mechanism 8 (see the attached figures 3 and 4 in the specification).

The conveying line 62 is provided with a driving chain 4 (see the description and the attached figure 5) through a motor; a plurality of workpiece clamps 5 are uniformly distributed on the driving chain 4; when the workpiece clamping device works, the driving chain 4 can drive the workpiece clamp 5 to synchronously rotate.

The workpiece holder 5 comprises a base plate 11, a fixed pressure plate 16, a movable pressure plate 17, a floating plate 14, a positioning block 15 and a clamping spring 20 (see the description of the attached drawings 6 and 7).

A bottom plate 11 is fixedly arranged on the driving chain 4 of the conveying line 62 through a connecting seat 10; a floating plate 14 is movably arranged on the bottom plate 11 through a guide rod 12 and a buffer spring 13 (see the attached figures 6 and 9 in the specification); the floating plate 14 can overcome the elasticity of the buffer spring 13 when being pressed and then move downwards under the guidance of the guide rod 12; when the floating plate 14 loses pressure, the floating plate 14 is rapidly restored under the elastic force of the buffer spring 13.

A positioning block 15 (see the attached figures 6 and 8 of the specification) is fixedly arranged on the floating plate 14; three groups of fixed pressing plates 16 are fixedly arranged on the floating plate 14 at one end of the positioning block 15 in parallel (see the attached figures 7 and 9 in the specification).

One side of the fixed pressing plate 16 is oppositely provided with a movable pressing plate 17; a loosening cylinder 18 is fixedly arranged at the lower end of the fixed pressure plate 16; the piston rod of the unclamping cylinder 18 is connected with the corresponding movable pressing plate 17; a guide bolt 19 is movably arranged between the fixed pressure plate 16 and the corresponding movable pressure plate 17; a clamping spring 20 is arranged between the nut of the guide bolt 19 and the outer side of the movable pressure plate 17; the movable platen 17 always has a tendency to approach the fixed platen 16 under the elastic force of the clamp springs 20. The purpose of thus arranging the movable platen 17 and the fixed platen 16 is to: so that during operation, the unclamping cylinder 18 can push the movable pressing plate 17 to separate from each other after overcoming the elastic force of the clamping spring 20, thereby facilitating people to place the pressing binder 3 inside, and then after the unclamping cylinder 18 is reset, the movable pressing plate 17 can approach towards the fixed pressing plate 16 under the elastic force of the clamping spring 20, and finally clamp and fix the pressing binder 3 under the cooperation of the movable pressing plate and the fixed pressing plate (see the description and the attached figure 6).

The inner side of the fixed pressure plate 16 and the inner side of the movable pressure plate 17 are oppositely provided with positioning notches 21 (refer to the description and the attached figure 10); the shape of the positioning notch 21 is consistent with the lower structure of the pressing connector 3, so that when the movable pressing plate 17 clamps and fastens the pressing connector 3 under the cooperation of the fixed pressing plate 16, the movable pressing plate 17 and the fixed pressing plate 16 can position the pressing connector 3 through the positioning notch 21, and the pressing connector 3 can be positioned between the movable pressing plate 17 and the fixed pressing plate 16 in a specified posture, thereby facilitating the subsequent pressing process.

The bottom plate 11 and the floating plate 14 are oppositely provided with a plurality of avoiding holes 36 (see the description and the attached figure 8). The purpose of providing the relief holes 36 is to: so that in operation, support insert rod 56 and spreader plate 57 of spreader 38 extend through relief hole 36 and above floating plate 14.

The lower end of the lifting plate 46 at one side of the workpiece clamping jaw 51 is movably provided with a pressing block 53 through a pressing spring 52 (see the attached figure 26 in the specification). During operation, the pressing block 53 can press and fix the cradle body 1 on the positioning support block 63.

The press-fit device 37 is provided with a spreader 38 (see the description and the attached drawing 28) below the work holder 5. The spreader 38 includes a lifting cylinder 54, a lifting plate 55, a support insert rod 56, and a spreader plate 57 (see fig. 29 in the specification). A push-lift plate 55 is arranged below the workpiece clamp 5 on one side of the conveying line 62 through a push-lift cylinder 54; a supporting inserted rod 56 is fixedly arranged on the lifting plate 55; a plurality of opening plates 57 are fixedly arranged on the lifting plate 55 at one side of the supporting inserted rod 56 (see the attached figure 29 in the specification); the lifting cylinder 54 operates to drive the lifting plate 55 and the opening plate 57 to move up and down.

The end of the opening plate 57 is symmetrically provided with an opening oblique tip 58 (see the description attached to fig. 29 and 31). During operation, the strutting oblique tip 58 can be propped open after being inserted into the cradle body 1 through the oblique surface, so that the purpose that the pressurizing combining piece 3 is conveniently inserted into and assembled in the cradle body 1 is achieved.

A prepress 39 is fixedly arranged above the conveying line 62 at one side of the spreader 38; the prepress 39 is located opposite the spreader 38 (see figure 28 of the specification). The prepress 39 comprises a longitudinal pushing cylinder 59, a prepressing cylinder 60 and a prepressing plate 61; a longitudinal pushing cylinder 59 is fixedly arranged on the conveying line 62 through a bracket; the end of the piston rod of the longitudinal pushing cylinder 59 is provided with a prepressing plate 61 (see the attached figure 33 in the specification) through a connecting plate and a prepressing cylinder 60. When working, the longitudinal pushing cylinder 59 can drive the prepressing cylinder 60 and the prepressing plate 61 to move back and forth, and the prepressing cylinder 60 can drive the prepressing plate 61 to move up and down.

The press-fitting mechanism 8 is provided with a transfer mechanism 9 (see the description and the attached figure 28) on one side. The transfer mechanism 9 comprises a vertical frame 28, a transverse sliding plate 29, a grabbing cylinder 30 and a grabbing jaw 31 (see the description and the attached figure 18). Two groups of transverse sliding plates 29 are slidably arranged on the vertical frame 28 through slide rails and cylinders; the cylinder operates to drive the cross slide 29 to slide back and forth on the stand 28. The transverse sliding plate 29 is provided with a grabbing cylinder 30; the lower end of the gripping cylinder 30 is provided with gripping jaws 31 (see fig. 18 of the description).

When the assembling device for the cradle body and the plastic parts of the spinning frame works, firstly, the loosening air cylinder 18 on the workpiece clamp 5 positioned on one side beside the cradle body feeding mechanism 6 acts to push the movable pressing plate 17 to overcome the elasticity of the clamping spring 20 and then separate the movable pressing plate 17 from the fixed pressing plate 16, and then other equipment or manual work is used for sequentially placing the three groups of pressing combined parts 3 between the movable pressing plate 17 and the fixed pressing plate 16; then, the air cylinder 18 is released to reset, and the movable pressure plate 17 can move close to each other under the action of the elastic force of the clamping spring 20, and finally the pressing joint 3 is clamped and fixed under the matching action (see the figure 6 in the specification).

After the pressurized connector 3 is assembled, the conveyor line 62 drives the work fixture 5 to move forward one station by the driving chain 4, so that the work fixture 5 with the pressurized connector 3 is moved to correspond to the press-fitting device 37 and then stops.

Then, the suction cylinder 23 on the rack feeding mechanism 6 sucks and fixes the cradle rack 1 at the upper end of the rack feeding line 22 by the suction head 24 and transfers the cradle rack to the upper side of the lifting plate 25 (see the attached fig. 14 and 15 in the specification). At the same time the frame loading line 22 moves a new cradle frame 1 to the end position in synchronism with this.

After the adsorption head 24 shifts the cradle support body 1 to the top of the jacking plate 25, the jacking cylinder ejects out the jacking plate 25 to enable the jacking plate to be inserted into the inside of the cradle support body 1, and then the adsorption head 24 loosens and resets the cradle support body 1. Then, the upper extrusion head 26 extrudes the cradle body 1 from the upper part, and the side extrusion head 27 extrudes the cradle body 1 from the end head to ensure that the interior of the cradle body is jointed and connected with the end surface of the jacking plate 25; so far, the aim of correcting the posture of the cradle body 1 is achieved. The upper extrusion head 26 and the side extrusion heads 27 are then repositioned.

After the upper extrusion head 26 and the side extrusion heads 27 are reset, the traverse sliding plate 29, the grabbing cylinder 30 and the grabbing jaw 31 of the transfer mechanism 9 cooperate with each other to clamp and place the cradle body 1 on the jacking plate 25 on the positioning support block 63 (see the attached fig. 22 and 23 of the specification) of the press-fitting device 37, and then reset. The jacking plates 25 are then reset.

After the cradle body 1 is placed on the positioning support block 63, the vibration feeder 32 on the material feeding mechanism 7 acts to make the plastic pieces 2 at the tail end enter the inner part of the workpiece bayonet 35 of the feeding block 34 under the action of mutual extrusion force, and then the feeding cylinder 33 drives the feeding block 34 to move forward one station and stop moving (see the attached fig. 19 and 20 of the specification).

At this time, the air cylinder on the press-fitting device 37 acts to push the cross sliding seat 44 to move to the upper part of the upper material block 34 on the sliding rail; then the lifting cylinder 45 acts to drive the clamping jaw air cylinder 48 to move downwards through the lifting plate 46 so as to grab the plastic pieces 2 on the feeding block 34 and then restore upwards. Then, the feeding cylinder 33 on the material feeding mechanism 7 drives the feeding block 34 to reset; the cylinder action pushes the cross sliding seat 44 to drive the clamping jaw cylinder 48 to move to the upper part of the cradle body 1.

After the work is finished, the push-pull air cylinder 49 acts to drive the clamping jaw air cylinder 48 to rotate around the rotating shaft 47 for a certain angle and then stop moving, and at the moment, the plastic part 2 and the clamping jaw air cylinder 48 are in an inclined state together. Then the lifting cylinder 45 acts to push the lifting plate 46 to move downwards; during the downward movement of the lifting plate 46, the pressing block 53 on the upper part of the lifting plate contacts with the cradle body 1 firstly and presses and fixes the lifting plate on the positioning supporting block 63, and then the lifting plate 46 continues to move downward, and during the process, the clamping jaw air cylinder 48 on the lifting plate 46 inserts the plastic part 2 into the end of the cradle body 1 to complete the installation. In this process, the pressing block 53 will act against the lifting plate 46 against the force of the pressing spring 52. After the plastic part 2 is installed, the lifting cylinder 45 drives the lifting plate 46 to reset; the push-pull air cylinder 49 drives the clamping jaw air cylinder 48 to reset.

After the plastic part 2 is assembled at the end of the cradle body 1, the longitudinal pushing cylinder 59 on the prepress 39 acts to push the prepressing plate 61 to the upper part of the pressurizing combination part 3 of the workpiece clamp 5; the prepressing cylinder 60 then drives the prepressing plate 61 to move downwards for a certain distance and then to reset. In this process, the prepressing plate 61 prepresses the pressing joint 3 downward to correct the position of the pressing joint 3, thereby preventing the incorrect mounting position of the pressing joint 3.

After the prepress 39 is operated, the lifting cylinder 54 of the spreader 38 is operated to push the spreader plate 57 to make its upper end pass through the avoiding hole 36 of the workpiece holder 5 and extend to above the press-fit joint 3 (see fig. 30 of the specification). Subsequently, the traverse sliding plate 29 of the transfer mechanism 9, the grabbing cylinder 30 and the grabbing jaw 31 are mutually matched to transfer the cradle body 1 with the plastic part 2 assembled to the upper end of the expanding plate 57 of the expander 38, and meanwhile, the transfer mechanism 9 places the cradle body 1 on the next cradle body 1 of the cradle body feeding mechanism 6 on the positioning support block 63.

After the cradle body 1 with the plastic part 2 assembled is placed at the upper end of the expanding plate 57 of the expander 38 by the transfer mechanism 9, the press-fitting cylinder 42 drives the press-fitting block 43 to move downwards for a certain distance, and the press-fitting block 43 extrudes the cradle body 1 in the process, so that the expanding oblique tip 58 on the expanding plate 57 can be inserted into the cradle body 1 through the oblique surface and then expanded. Then the press-fitting cylinder 42 and the pushing cylinder 54 synchronously act to make the press-fitting block 43 and the opening plate 57 keep relatively immovable state to drive the cradle body 1 to move downwards, and when the press-fitting part 3 on the workpiece fixture 5 is completely inserted into the cradle body 1, the press-fitting block 43 and the opening plate 57 stop acting. Then, the pushing cylinder 54 drives the opening plate 57 to reset, the press-fitting cylinder 42 drives the press-fitting block 43 to reset, so that the assembly device of the cradle body and the plastic part of the spinning frame completely completes the assembly work of the cradle body 1, the plastic part 2 and the pressing combined part 3, then the conveying line 62 drives the workpiece clamp 5 to move forward one station through the driving chain 4 to carry out the assembly of other working procedures, and the assembly device of the cradle body and the plastic part of the spinning frame can enter the next working cycle.

The assembly device for the cradle body and the plastic part of the spinning frame has compact structure and ingenious design; the assembly work among the cradle frame body 1, the plastic part 2 and the pressurizing combining part 3 of the cradle of the spinning frame can be mechanically completed, the problems of high labor intensity and low working efficiency existing in manual assembly are solved, and the requirement of high-efficiency assembly and use of enterprises is met.
