Specifically, the fixed frame 3 is fixed with a track 4, the workpiece placement rack 1 slides on the track 4, and a push cylinder 5 is installed on the fixed frame 3, and the push cylinder 5 is horizontally arranged. A connecting plate 6 is fixed to the end of the bottom of the workpiece placement rack 1 away from the push cylinder 5, and the piston rod of the push cylinder 5 is fixed to the connecting plate 6. The push cylinder 5 drives the workpiece placement rack 1 to translate to the slide-out position and the working position. The slide-out position is used to place the bushing 7, and the working position is used to stamp the bushing 7.

[0028] A positioning cylinder 8 is fixed on the workpiece placement frame 1, and two positioning cylinders 8 are symmetrically arranged at one end away from the connecting plate 6. A first stop block 9 is fixed on the piston rod of the positioning cylinder 8, and the first stop block 9 is located below the workpiece placement frame 1. A second stop block 10 is fixed on the fixed frame 3. When the workpiece placement frame 1 moves, the first stop block 9 and the second stop block 10 are staggered. When the workpiece placement frame 1 moves to the working position, the first stop block 9 moves down to abut against the second brake block. Due to the positional relationship, the piston rod of the push cylinder 5 passes through the second stop block 10. A third stop block 11 is also fixed on the fixed frame 3, and the third stop block 11 is located at one end away from the first stop block 9. That is, when the workpiece placement frame 1 is in the working position, one end inside abuts the third stop block 11, and one end outside abuts against the second stop block 10 after the first stop block 9 moves down. The workpiece placement frame 1 has a limit ring 12, and the limit ring 12 is used to limit the horizontal movement of the battery box 37 front, back, left, and right.

[0029] The bushing punching system includes a transverse slide rail 13 arranged on a frame, a sliding frame 14 slidably arranged on the transverse slide rail 13, a longitudinal slide rail 15 installed on the sliding frame 14, and a punch installed on the longitudinal slide rail 15. The transverse slide rail 13 and the track 4 are arranged in parallel, and the longitudinal slide rail 15 is fixed on the U-shaped frame 2. The sliding frame 14 is a gantry frame here.

[0031] The longitudinal drive member includes a motor 22 fixed on the mounting frame 16 and a transmission wheel fixed on the output shaft of the motor 22. The transmission wheel is frictionally matched or tooth-engaged with the sliding frame 14. If the transmission wheel is a rubber wheel, a frictional match can be adopted. If the transmission wheel is set as a gear, a rack parallel to the longitudinal slide rail 15 can be set on the sliding frame 14, and the gear is meshed with the rack.

[0032] The push member includes a push cylinder 23, a magnet 24, and a limit block 25. The magnet 24 is fixed on the piston rod of the push cylinder 23, and the limit block 25 is fixed on the cylinder body of the push cylinder 23. The magnet 24 has a semicircular arc groove, and the limit block 25 is at least partially located below the arc groove.

[0033] The bushing stamping system also includes a feeding mechanism and a receiving mechanism. The feeding mechanism includes a vibration plate 26, a feeding track 27 arranged on the vibration plate 26, and a positioning block 28 arranged on the sliding frame 14, wherein a fixing plate 29 is fixed on the sliding frame 14, and the vibration plate 26 is fixed on the fixing plate 29. The feeding track 27 is inclined downward from the connection of the vibration plate 26 so that the bushing 7 can slide down smoothly. The end of the feeding track 274 has a circular feeding port, and the diameter of the feeding port is slightly larger than the outer diameter of the bushing 7. The receiving mechanism is located on the mounting frame 16, and when the mounting frame 16 moves to abut the positioning block 28, the feeding mechanism is located below the discharge port of the feeding track 27.

[0034] The material receiving device includes a material receiving rod 30, a first clamping mechanism and a second clamping mechanism fixed on the mounting frame 16 for clamping or releasing the material receiving rod 30, and at least one of the first clamping mechanism and the second clamping mechanism is kept in a clamping state, a space for accommodating a bushing 7 is formed between the first clamping mechanism and the second clamping mechanism in the height direction, and an abutting mechanism for abutting or releasing the bushing 7 is also fixed on the mounting frame 16, and the abutting mechanism is located above the first clamping mechanism and the second clamping mechanism. The upper end of the material receiving rod 30 has a chamfer so that the bushing 7 can enter or fall, and when the mounting frame 16 abuts the positioning block 28, the material receiving rod 30 is located directly below the material discharge port and is coaxially arranged.

[0035] The first clamping mechanism includes two symmetrically arranged first clamping cylinders 31, a first clamping block 32 fixed on the piston rod of the first clamping cylinder 31, and the first clamping block 32 has an arc-shaped clamping surface. The second clamping mechanism includes two symmetrically arranged second clamping cylinders 33, a second clamping block 34 fixed on the piston rod of the second clamping cylinder 33, and the second clamping block 34 has an arc-shaped clamping surface. The abutting mechanism includes an abutting cylinder 35, and an abutting block 36 fixed on the piston rod of the abutting cylinder 35, and the abutting block 36 has an arc-shaped surface abutting the outer wall of the bushing 7.

[0036] It should be noted here that the material receiving rod 30 is limited only by the first clamping mechanism and the second clamping mechanism.

[0037] The abutment mechanism is located above the first clamping mechanism, and the second clamping mechanism is located below the first clamping mechanism. When the receiving rod 30 receives the material, the first clamping mechanism and the second clamping mechanism both clamp the receiving rod 30, the bushing 7 is sleeved on the receiving rod 30, and the lowest receiving rod 30 abuts the first clamping block 32 of the first clamping mechanism. And the abutment mechanism does not work at this time. Each time the material is unloaded, the abutment mechanism first abuts the second bushing 7 at the bottom, and the first clamping mechanism is released, and the lowest bushing 7 falls into the space between the first clamping mechanism and the second clamping mechanism. Then the first clamping mechanism resets the clamping, releases the abutment mechanism, and the bushing 7 above the first clamping mechanism falls and abuts the first clamping block 32 of the first clamping mechanism again. After that, the second clamping mechanism is released, and the bushing 7 falls along the receiving rod 30 to the limit block 25 and is adsorbed by the magnet 24. The preparation work before the stamping of the bushing 7 is completed.

[0038] When the mounting frame 16 moves along the longitudinal slide rail 15 , the telescopic positioning pin 21 is located below the flange edge 38 of the battery box 37 . During stamping preparation, the first cylinder 19 drives the support plate 20 to move upward until the support plate 20 abuts against the lower surface of the flange edge 38 , and at this time, the telescopic positioning pin 21 is located in the bushing mounting hole 39 on the flange edge 38 .

[0039] The push cylinder 23 pushes the magnet 24 until the bushing 7 is located directly below the punch head 18. The punch cylinder 17 works, and the punch head 18 punches the bushing 7 into the bushing mounting hole 39. During the punching process, the telescopic positioning pin 21 is retracted into the pin hole of the support plate 20. The punch head 18 preferably has a little magnetism, and its function is the same as that of a magnetic screwdriver.
