[0022] By rotating and pressing the handle 12 downward, the handle fixing clamp 11 is driven to rotate, and the rotation of the handle fixing clamp 11 drives the compression spring upper cover 13 to rotate and move downward, so that the compression spring 14 is compressed, driving the compression spring lower cover 15 to move downward, thereby driving the sliding mounting plate 16 to descend under the guidance of the lifting slide rail 21, thereby driving the punching cutter head 18 to descend. During the descent, the unloading plate 20 first contacts the surface of the workpiece, and presses and fixes the workpiece through the elastic force of the spring guide column 19 to prevent the workpiece from deflecting during the tooth punching. Then the upper template 17 continues to descend, driving the punching cutter head 18 to pass through the unloading plate 20 to punch the workpiece. After the tooth punching is completed, the handle 12 is released, and the sliding mounting plate 16 is driven to rise under the joint action of the reset spring 22 and the compression spring 14. During the rising process, after the punching cutter head 18 rises to the top of the unloading plate 20, the punching cutter head 18 is separated from the workpiece by the unloading plate 20, and then the unloading plate 20 rises again;

[0023] A base slide rail 2 is provided at the bottom of the punching platform 3, a base 1 is provided on both sides of the bottom of the base slide rail 2, a C-shaped slide seat 5 is slidably connected to the base slide rail 2, and a positioning plate 4 is provided on one side of the top of the punching platform 3.

[0025] A stepping bar 6 is provided on one side of the top surface of the punching tooth platform 3, and a twisting plunger 25 is provided on one side of the lower bearing plate 24. The twisting plunger 25 is located above the stepping bar 6, and a stepping spring baffle 26 is provided on one side of the C-shaped slide 5. A spring sleeve rod 27 is provided inside the stepping spring baffle 26. The sleeve rod of the spring sleeve rod 27 is movably connected with the stepping spring baffle 26, and the spring of the spring sleeve rod 27 is located below the stepping spring baffle 26.

During the movement of the C-shaped slide 5, the bearing 29 contacts the teeth on the stepping bar 6 to perform stepping movement.

[0027] When the bearing 29 moves to the top of the tooth of the stepping bar 6, the spring guide rod 27 is compressed, the stepping bearing seat 28 and the bearing 29 will rise, and when the bearing 29 moves between the teeth of the stepping bar 6, it is positioned by the V-shaped gap between the teeth. When the C-type slide 5 moves left and right, the stepping movement is achieved by the frustration generated when the bearing 29 and the stepping bar 6 move. After the movement, the C-type slide 5 is fixed by the abutment between the twisting plunger 25 and the stepping bar 6.

[0028] A stop screw 23 is provided on the outer wall of one side of the upper template 17, and the stop screw 23 is located below the lifting rail 21. A return spring 22 is provided on one side of the outer wall of the lifting rail 21, and the bottom end of the return spring 22 is connected to the stop screw 23. After the teeth are punched, the handle 12 is released, and the sliding mounting plate 16 is driven to rise under the joint action of the return spring 22 and the compression spring 14, so as to prepare for the next drop of the teeth.

[0029] A rotating handle is provided at the top of the gear shaft 8 to facilitate the rotation of the gear shaft 8.

[0030] When the mechanical gear punching machine is in use, the workpiece that needs to be punched is placed on the gear punching platform 3, the workpiece is positioned by the positioning plate 4, and then the gear shaft 8 is rotated to drive the gear 9 to rotate. Through the meshing of the gear 9 and the rack 10, the C-type slide 5 and its components can be driven to move left and right under the guidance of the base slide rail 2. During the movement of the C-type slide 5, the bearing 29 contacts the teeth on the stepping bar 6 for stepping movement. At this time, when the bearing 29 moves to the top of the teeth of the stepping bar 6, the spring guide rod 27 is compressed, and the stepping bearing seat 28 and the bearing 29 will rise. When the bearing 29 moves between the teeth of the stepping bar 6, it is positioned by the V-shaped gap between the teeth. When the C-type slide 5 moves left and right, the stepping movement is achieved by the frustration generated when the bearing 29 and the stepping bar 6 move. After moving, the C-type slide 5 is fixed by twisting the plunger 25 and the abutment with the stepping bar 6.

[0031] When it moves to the tooth punching station, by rotating and pressing the handle 12 downward, the handle fixing clamp 11 is driven to rotate, and the rotation of the handle fixing clamp 11 drives the compression spring upper cover 13 to rotate and move downward, so that the compression spring 14 is compressed, driving the compression spring lower cover 15 to move downward, thereby driving the sliding mounting plate 16 to descend under the guidance of the lifting slide rail 21, thereby driving the tooth punching cutter head 18 to descend. During the descent, the unloading plate 20 first contacts the surface of the workpiece, and presses and fixes the workpiece through the elastic force of the spring guide column 19 to prevent the workpiece from deflecting during tooth punching. Then the upper template 17 continues to descend, driving the tooth punching cutter head 18 to pass through the unloading plate 20 to punch the workpiece. After the tooth punching is completed, the handle 12 is released, and the sliding mounting plate 16 is driven to rise under the joint action of the reset spring 22 and the compression spring 14. During the rising process, after the tooth punching cutter head 18 rises to the top of the unloading plate 20, the unloading plate 20 separates the tooth punching cutter head 18 from the workpiece, and then the unloading plate 20 rises again;

[0032] The entire tooth punching machine has a compact structure and occupies a small area. The tooth punching cutter head 18 is controlled by the stepping bar 6 to move step by step, so that the tooth punching position can be controlled more accurately. The tooth punching cutter head 18 is lowered by rotating the handle 12, which saves effort and facilitates accurate and convenient tooth punching during small-batch trial production.

[0033] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
