[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The utility model provides Figure 1-4 A quick clamp for punching holes in a metal chain is shown, comprising an operating table 1, a punching device 2 for punching holes in the chain is arranged on the top of the operating table 1, a clamping assembly for clamping the chain is symmetrically arranged on the top of the operating table 1, a driving assembly for driving the clamping assembly to move is arranged at the bottom of the punching device 2, the driving assembly comprises a rack 5 and a bidirectional screw 9, and a transmission member for power transmission is arranged between the rack 5 and the bidirectional screw 9.

[0020] Specifically, the bottom end of the punching device 2 is fixedly connected to a mounting frame 3 for mounting the punching device 2, the bottom end of the mounting frame 3 is fixedly connected to the top of the operating table 1, the outer wall of the output end of the punching device 2 is fixedly connected to an L-shaped plate 4 for driving the rack 5 to move, a cavity is opened inside the operating table 1, and an insertion hole for inserting the rack 5 is opened at the top of the operating table 1.

[0021] Furthermore, the punching device 2 is a hydraulic punching device, which is electrically connected to an external control power supply. The output end of the punching device 2 is fixedly connected to a punching plate. When the chain stops at the bottom end of the punching device 2, it extends out through the output end of the punching device 2 to drive the punching plate to punch holes in the chain. A circular groove is provided on the top of the operating table 1 to allow the punched waste to fall onto the landslide inside the operating table 1 and slide out along the landslide. The two ends of the L-shaped plate 4 are respectively fixedly connected to the output end of the punching device 2 and one side of the rack 5, so that the vertical movement of the rack 5 is synchronized with the movement of the output end of the punching device 2, and the size of the interlaced hole is 1.2 times the size of the rack 5.

[0022] Specifically, the transmission member includes a rotating gear 6 and a transmission gear 7. The rotating gear 6 and the rack 5 are meshed on opposite sides thereof. The rotating gear 6 and the transmission gear 7 are meshed on opposite sides thereof. The outer wall of the bidirectional screw 9 is sleeved with a driving gear 8. The driving gear 8 is meshed on opposite sides of the transmission gear 7. The rotating gear 6, the transmission gear 7 and the driving gear 8 are all arranged in the cavity.

[0023] Furthermore, a round rod is fixedly connected to the back of the rotating gear 6 and the transmission gear 7, and a first bearing is sleeved on the outer wall of the round rod near one end of the inner wall of the cavity. The first bearing is fixedly connected to the back of the inner wall of the cavity, thereby ensuring the fixation of the positions of the rotating gear 6 and the transmission gear 7 without affecting the rotation of the rotating gear 6 and the transmission gear 7. The driving gear 8 is fixedly sleeved on one end of the bidirectional screw 9 near the back of the inner wall of the cavity. The rotating gear 6, the transmission gear 7 and the driving gear 8 are in the same straight line. The rack 5, the rotating gear 6, the transmission gear 7 and the driving gear 8 are meshed with each other in sequence. Second bearings are respectively sleeved on both ends of the bidirectional screw 9, and the side of the second bearing away from the bidirectional screw 9 is fixedly connected to the inner wall of the cavity. Therefore, when the rack 5 moves vertically downward, the rotational power is transmitted through the rotating gear 6, the transmission gear 7 and the driving gear 8, so that the bidirectional screw 9 moves counterclockwise. When the rack 5 moves vertically upward, the bidirectional screw 9 moves clockwise.

[0024] Specifically, the clamping assembly includes a clamping member and a moving member, the clamping member includes a clamping block 12, and the moving member includes a moving rod 10. An adjusting screw 11 for adjusting the distance between the clamping block 12 and the moving rod 10 is provided at one end of the clamping block 12. A first thread groove for threadedly inserting and connecting the adjusting screw 11 is provided at the top of the moving rod 10. A second thread groove for threadedly inserting and connecting the bidirectional screw 9 is provided at the bottom of the moving rod 10. A limiting rod 13 for limiting the rotation of the clamping block 12 is provided at the top of the clamping block 12. A fixed block 14 is fixedly connected to the top of the clamping block 12. The outer wall of the fixed block 14 is fixedly connected to one end of the limiting rod 13. An insertion block 15 is fixedly connected to the top of the moving rod 10. A circular through groove is provided on the outer wall of the insertion block 15. The other end of the limiting rod 13 is inserted and connected to the circular through groove.

[0025] Furthermore, a moving hole for moving the moving rod 10 is symmetrically opened at the top of the operating table 1, and the width of the moving hole is 1.02 times the width of the moving rod 10. The clamping components are symmetrically arranged on both sides of the punching plate, and a V-shaped groove is opened on the opposite side of the two clamping blocks 12, so as to clamp the two sides of different chains. The second thread groove at the bottom of the moving rod 10 is meshed with the thread of the outer wall of the bidirectional screw 9. The bidirectional screw 9 drives the moving rod 10, and the moving rod 10 drives the adjusting screw 11, and the adjusting screw 11 drives the clamping block 12 to move. When the bidirectional screw 9 moves counterclockwise, it drives the relatively arranged clamping blocks 12 to move toward each other. When the bidirectional screw 9 moves counterclockwise, it drives the relatively arranged clamping blocks 12 to move toward each other. When the rod 9 rotates clockwise, it drives the symmetrically arranged clamping blocks 12 to move northward, thereby realizing automatic clamping and fixing and automatic loosening of the chain. There is no need to manually fix the clamping chain, saving manpower. The first thread groove on the top of the mobile rod 10 is meshed with the thread on the outer wall of the adjusting screw 11. The outer wall of the adjusting screw 11 close to one end of the clamping block 12 is fixedly sleeved with a third bearing. One side of the third bearing is fixedly connected to one side of the clamping block 12. By rotating the adjusting screw 11, the distance between the clamping block 12 and the mobile rod 10 can be adjusted, thereby adjusting the distance between the symmetrically arranged clamping blocks 12 to meet the clamping and fixing of chains of different specifications.
