When the output end of the pushing device 9 leaves the two sliders 12, the first return spring 14 releases energy to push the two sliders 12 back to the initial position.

[0026] As attached Figure 4 and attached Figure 5As shown, an outer sleeve 15, a top core 16 and a second return spring 17 are further provided on the slider 12. The top core 16 is installed on the slider 12. The outer sleeve 15 is slidably arranged on the outer periphery of the top core 16.

When the second return spring 17 is in a free state, one end of the top core 16 close to the positioning seat 11 is arranged inside the outer sleeve 15. That is, during the riveting process, the outer sleeve 15 first pre-presses the workpiece. As the relative displacement amount between the outer sleeve 15 and the top core 16 increases, the end of the top core 16 passes through the through hole 18 and presses the workpiece.

[0027] As shown in the attached Figure 5 As shown, a mounting hole 19 is provided through the slider 12. The outer sleeve 15 and the top core 16 are arranged in the mounting hole 19. A limiting block 20 for limiting the top core 16 is provided on one side of the slider 12 away from the positioning seat 11.

[0030] As shown in the attached Figure 2 and the attached Figure 3As shown, the pushing device 9 includes a driving motor 26, a transmission box 27, a screw 28, a control console 29, a connecting seat 30, a pressing plate 31 and a pressing foot 32. Two first guide pillars 33 are provided on the working platform 8. A guide hole 34 matching the first guide pillars 33 is provided on the control console 29. The screw 28 is rotatably mounted on the control console 29. The driving motor 26 drives the screw 28 to rotate through the transmission box 27. The transmission box 27 can be a worm gear transmission box 27 or a gear transmission box 27. An upper beam 35 is also provided between the two first guide pillars 33. The upper beam 35 is provided with a screw hole 36 that cooperates with the screw rod 28, the connecting seat 30 is installed on the console 29, the connecting seat 30 is provided with a connecting rod 37, and the connecting rod 37 is connected to the pressing plate 31. There are two presser feet 32, and the two presser feet 32 ​​are respectively arranged above the corresponding sliders 12. The upper end surface of the slider 12 is provided with a guiding inclined surface 38 that cooperates with the presser foot 32 when the presser foot 32 moves downward. When the presser foot 32 applies pressure on the guiding inclined surface 38 of the slider 12, its horizontal component force pushes the slider 12 to move.

[0031] As attached Figure 2 As shown, the lower end of the presser foot 32 is rollingly connected with a press wheel 39, and the press wheel 39 cooperates with the guide slope 38, which can significantly reduce the friction between the presser foot 32 and the slider 12, which can not only improve the service life of the parts, but also.

[0032] As attached Figure 2 As shown, the tooling base 10 is further provided with two second guide pillars 40 , and the pressing plate 31 is provided with a guide sleeve 41 sleeved on the outer circumference of the second guide pillars 40 , which can guide the pressing plate 31 to ensure the stability of its vertical displacement.

[0033] As attached Figure 3 and attached Figure 4 As shown, it also includes a cylinder 42, which is installed on the tooling base 10. The tooling base 10 is provided with a guide groove 43 extending along the front-to-back direction. The bottom plate 13 is arranged in the guide groove 43. The protruding end of the cylinder 42 is linked with the bottom plate 13 to drive the bottom plate 13 to slide along the extension direction of the guide groove 43, so that it can be switched between the working position and the non-working position, which is convenient for taking and placing the moving contact piece 3 assembly.

[0034] As attached Figure 4 As shown, the positioning seat 11 is provided with a positioning hole 44 for inserting the moving iron core 2, so as to position the moving contact piece 3 assembly.

[0035] Working principle: This application adopts riveting tooling to rivet the contact bracket 1 of the moving contact assembly of the new energy contactor. When working, first position the moving contact assembly 3 on the positioning seat 11, and then drive the pushing device 9. The driving motor 26 of the pushing device 9 drives the screw 28 to rotate through the transmission box 27. Since the screw 28 is threadedly matched with the screw hole 36 on the upper beam 35, when the screw 28 rotates, the control console 29 drives the parts connected to it downward, and the pressure plate 31 under the control console 29 drives the presser foot 32 downward. When the pressure wheel 39 on the presser foot 32 cooperates with the guide slope 38 on the slider 12, the two sliders 1 2 move towards each other, the outer sleeve 15 on the slider 12 first pre-presses the two sides of the U-shaped bracket 4, and at the same time, the outer sleeve 15 overcomes the spring force and moves until the top core 16 pushes out the opening 18 on the outer sleeve 15 and squeezes the two sides of the U-shaped bracket 4, so that the plug-in protrusion 7 on the support plate 5 is firmly pressed into the plug hole 6 on the U-shaped bracket 4, completing the riveting process, and then the pushing device 9 drives the console 29 upward, the slider 12 retreats to the initial position under the action of the first reset spring 14, and the outer sleeve 15 retreats to the initial position under the action of the second reset spring 17, and the moving contact piece 3 assembly is taken away to facilitate the riveting operation of the next workpiece. It can realize the rapid riveting of the contact bracket 1, which not only greatly reduces the labor intensity of workers, but also significantly improves production efficiency, and can bring good economic benefits to the enterprise.
