DETAILED DESCRIPTION

[0019] The automobile clutch circlip pressing device comprises an extrusion cylinder 2, a frame 1, an inner shrinkage cylinder 7, a transition slide plate 8 and a pressing head 3 (see the attached manual). Figure 1 and 2 ).

[0020] The frame 1 is provided with a pressing head 3 (see the appendix of the manual) through the extrusion cylinder 2. Figure 1 and 2 ). When the extrusion cylinder 2 is working, it can drive the pressure head 3 to move up and down.

[0021] The pressure head 3 includes a pressure sleeve 10, a pressure claw 12, a floating pressure pin 15 and a buffer spring 14 (see the attached manual). Figure 5 and 7). A pressing sleeve 10 is fixedly mounted at the lower end of the extrusion cylinder 2; a plurality of pressing claws 12 are movably mounted on the circumferential surface of the pressing sleeve 10 through a rotating pin 11; a floating pressing pin 15 is mounted on the extrusion cylinder 2 above the pressing claw 12 through an assembly sleeve 13 and a buffer spring 14; the bottom end of the floating pressing pin 15 is in contact with the upper end of the pressing claw 12.

[0022] The middle of the pressing claw 12 is provided with a rotating hole 16; the upper end of the pressing claw 12 is provided with a limiting protrusion 17; the inner side of the limiting protrusion 17 is intermittently connected to the assembly sleeve 13; the lower end of the pressing claw 12 is provided with an extrusion protrusion 18 (see the attached manual Figure 5 and 7 ).

[0023] Under the action of the elastic force of the buffer spring 14, the floating pressing pin 15 always has a tendency to press the pressing claw 12. The pressing point of the floating pressing pin 15 is located at a position on one side of the floating pressing pin 15 close to the center of the pressing sleeve 10, so the pressing claw 12 always has a tendency to rotate inward under the pressure of the floating pressing pin 15. When the limiting protrusion 17 contacts the side of the assembly sleeve 13, the assembly sleeve 13 will further limit the rotation of the pressing claw 12, thereby achieving the purpose of limiting the pressing claw 12.

[0024] A mounting plate 4 is symmetrically fixed on the frame 1 below the pressure head 3; a positioning cylinder 5 is mounted on the mounting plate 4; a retracting cylinder 7 is mounted on the lower end of the positioning cylinder 5 through a lifting plate 6 (see the attached manual). Figure 1 and 2 The positioning cylinder 5 can drive the inner shrink tube 7 to move up and down through the lifting plate 6. The inner shrink tube 7 has a conical structure with a wide top and a narrow bottom (see the attached manual). Figure 3 ).

[0025] A transition slide plate 8 is provided on one side of the upper end of the inner shrinkage tube 7; a transition slide groove 9 is provided on the transition slide plate 8 (see the attached manual Figure 1 ); The transition chute 9 is connected to the inner shrinkage tube 7 through the guide slide hole 19 provided on the lifting plate 6 (see the attached manual Figure 2 ).

[0026] When the automobile clutch retaining spring press-fitting device is working, when the automobile clutch to be assembled moves to the bottom of the inner shrinkage tube 7, the positioning cylinder 5 drives the inner shrinkage tube 7 to move downward through the lifting plate 6 to fix the workpiece.

[0027] After the above work is completed, the circlip 20 to be assembled slides into the interior of the inner shrink tube 7 through the transition slide groove 9 and the guide slide hole 19 on the transition slide plate 8. Then the extrusion cylinder 2 drives the pressure head 3 to move down into the interior of the inner shrink tube 7. During this process, the pressure claw 12 will press the circlip 20 along the inner surface of the inner shrink tube 7 to make it move downward (see the attached manual). Figure 5), and finally the circlip 20 is pressed down into the automobile clutch, so that the assembly work can be completed. After installation, after the various components of the automobile clutch circlip press-fit device are reset, the circlip press-fit device can enter the next working cycle.

[0028] The automobile clutch retaining spring press-fitting device has a compact structure and an ingenious design. It can complete the press-fitting work of the retaining spring by driving the pressing head 3 with a single cylinder, thereby solving the problem of high assembly failure rate when the existing installation device requires multiple cylinders to control the pressing fingers. The device is particularly suitable for the requirements of automobile clutch retaining spring press-fitting.
