[0033] In this embodiment, the linkage screw 81 is concave in shape so that the roller 83 can be rotatably connected, thereby lifting the drive belt to move up and down; there is a limiting block on the outside of the linkage screw 81 to limit its sliding range in the support box 7, which range is the width of the drive belt.

[0035] In this embodiment, the cross-section of the connecting frame 85 is similar to an F-shape, and the recessed part is offset from the top of the linkage screw 81 to avoid affecting the rotation of the linkage screw 81; when the positioning bolt 88 is threadedly connected to the connecting column 86, it will abut against the plug-in rod 87 to position the plug-in rod 87, thereby positioning the plug-in rod 87. At this time, the linkage block 89 will be connected to the connecting column 86 through the plug-in rod 87 and the positioning bolt 88, so that when the positioning fixture 5 moves up, it can be transmitted to move the receiving box 82.

[0036] In a further embodiment, the linkage wheel 91 is rotatably connected inside the support box 7. The linkage wheel 91 is located above the linkage screw 81.

The fan 94 is located above the positioning fixture 5, and a pulley is installed at the shaft of the fan 94, so that the fan 94 can be connected to the transmission shaft 93 through the linkage belt 95; pulleys are installed at both the upper and lower ends of the transmission shaft 93, so that its top end is connected to the transmission belt 92 and the bottom end is connected to the linkage belt 95 for synchronous transmission.

[0040] The working principle of the present utility model is as follows:

[0041] When punching parts is required, the parts can be fixed above the positioning fixture 5. At this time, the driving motor 2 is operated through an external control device, and then the driving shaft 3 will drive the pulley 4 to rotate. The rotation of the driving shaft 3 will drive the cutter head at the bottom to rotate, and the rotation of the pulley 4 will drive the linkage screw 81 to rotate through the driving belt, so that the positioning fixture 5 starts to move upward, thereby performing a punching operation on the parts;

[0042] Before the above punching operation, the positioning bolt 88 can be loosened to make the insertion rod 87 drive the linkage block 89 to slide within the limit range of the connecting column 86, and the scale aligned with the upper end face of the linkage block 89 can be selected according to needs. This scale is the punching depth. After determination, the positioning bolt 88 can be tightened to position the insertion rod 87, so that the linkage block 89 is at a certain height above the positioning fixture 5. At this time, the driving motor 2 is started again. As the positioning fixture 5 continues to move upward, the positioning fixture 5 will contact the bottom of the linkage block 89. At this time, through the insertion rod 87, the connecting column 86 and the connecting frame 85 will drive the receiving box 82 inside the support box 7 to move upward. Since the driving belt passes through the receiving box 82, the driving belt will move upward. During the upward movement, the driving belt will gradually disconnect from the linkage screw 81 and gradually connect to the linkage wheel 91 until the driving belt is completely connected to the linkage wheel 91. At this time, the linkage screw 81 will lose the power source and stop rotating, so that the positioning fixture 5 stops at a specific height. Since the thickness of the linkage block 89 is the same as the width of the driving belt, the punching depth at this time is the depth set at the beginning;

[0043] When the drive belt is connected to the linkage wheel 91, it will drive the linkage wheel 91 to rotate. As a result, the drive shaft 93 will be driven to rotate through the transmission belt 92, and the fan 94 will be driven to rotate through the linkage belt 95 at the bottom of the drive shaft 93, so that the air flow can start to flow, and the parts after punching can be air-cooled and the debris can be blown away.

[0044] After punching, the positioning bolt 88 can be loosened and the connecting column 86 can be pressed down, so that the drive belt is reconnected to the linkage screw 81. At this time, the drive motor 2 can be driven in the reverse direction.

[0045] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
