[0035] Furthermore, Figure 3 and Figure 4 As shown, a positioning block 34 is disposed at the upper end of the movable mounting seat 32 , an upper surface of the positioning block 34 is provided with a fixing frame positioning boss 35 protruding upward, and an axle rod positioning groove 36 is opened on the upper surface of the positioning block 34 .

[0036] In the process of implementing the hinge riveting processing operation of the laptop computer using the pull-out punch structure of the first embodiment of the present invention, the driving cylinder 33 first drives the movable mounting seat 32 to move forward to the loading position. At this time, the staff first assembles and docks the fixing frame 101 and the shaft rod 102 of the hinge product, and then places the fixing frame 101 and the shaft rod 102 on the upper surface of the positioning block 34, wherein the fixing frame 101 is positioned by the fixing frame positioning boss 35 on the positioning block 34, and the fixing frame positioning boss 35 is inserted into the corresponding hole position of the fixing frame 101, and the shaft rod 102 is positioned by the shaft rod positioning groove 36 on the upper surface of the positioning block 34; the fixing frame 101 and the shaft rod 102 of the hinge product to be fixed are respectively positioned and placed on the positioning block 34. After the positioning block 34 is positioned, the driving cylinder 33 is activated and drives the movable mounting seat 32 to move backward to the riveting operation position; after the movable mounting seat 32 moves backward to the riveting operation position, the automatic riveting assembly 4 is activated, and the lifting drive mechanism 42 of the automatic riveting assembly 4 drives the movable pressure rod 41 to move downward, so that the movable pressure rod 41 presses downward against the fixed frame 101 and the shaft rod 102 assembled together, thereby completing the riveting operation; after the riveting operation is completed, the driving cylinder 33 drives the movable mounting seat 32 to move forward to the loading position. At this time, the staff removes the fixed frame 101 and the shaft rod 102 that have been riveted from the positioning block 34, and then positions the fixed frame 101 and the shaft rod 102 that have not been riveted on the positioning block 34.

[0037] It should be emphasized that the loading assembly 3 of the first embodiment can realize the switching and movement of the workpiece between the loading position and the riveting operation position, with a high degree of automation, and can accurately position the fixed frame 101 and the shaft 102 of the hinge product through the fixed frame positioning boss 35 and the shaft positioning groove 36 on the positioning placement block 34, thereby being effectively applicable to the riveting processing requirements of the fixed frame 101 and the shaft 102 of the hinge product.

[0038] In addition, when the pull-out punch structure of the first embodiment is working, the staff only needs to perform the loading and unloading operations; compared with the prior art, the first embodiment does not need to repeatedly operate the limit plate and the threaded rod structure, that is, the working efficiency of the first embodiment is higher.
