Since the limit frame 2-41 is provided, and the first clamp 2-1 and the second clamp 2-2 are located in the limit space 2-42 of the limit frame 2-41, the opening size of the first clamp 2-1 and the second clamp 2-2 can be limited, that is, the size of the conical hole 2-12 can be limited, so that even if the conical hole 2-12 is opened, the second workpiece will not fall out of the conical hole 2-12, and the limit mechanism 2-4 plays a limiting role.

When the third conveying device 13 inserts the second workpiece whose angle has been corrected on the angle correction device 3 into the through hole 4-24 of the punch mounting seat 4-21, the pneumatic connector 4-26 is started to introduce a vacuum to adsorb the second workpiece, and the driving device 4-23 pushes the punch assembly 4-2 downward, and the punch mounting seat 4-21 in the punch assembly 4-2 moves vertically relative to the punch fixing frame 4-1 through the moving pair 4-11, so that the driving device 4-23 presses the punch assembly 4-2 downward. The press-fitting structure must be installed on the lower base with the first workpiece; the driving device 4-23 continues to extend to press the pop-up punch 4-22 in the punch assembly 4-2 onto the surface of the punch mounting seat 4-21. At this time, the elastic member 4-25 is compressed, and the punch 4-22 presses the second workpiece into the hole of the lower base, completing the press-fitting process between the first workpiece and the second workpiece (the first workpiece and the second workpiece are pressed to form a finished workpiece); the driving device 4-23 is actuated to move the punch assembly 4-2 upward, and the punch 4-22 pops up to the upper limit position under the elastic force of the elastic member 4-25, entering the second workpiece of the next cycle. The punch 4-22 of the punch device cooperates with the through hole 4-24 and is connected to the accommodating chamber 4-27 through the pneumatic joint 4-26, so that the punch device has the function of adsorbing and positioning the second workpiece, and the punch device of this embodiment can automatically install the second workpiece on the lower base of the first workpiece, without manual operation for the press-fitting process, thus realizing press-fitting automation and improving production efficiency, and the punch device has a small and compact structure and saves space.The elastic member 4-25 is arranged on the punch mounting seat 4-21, which plays a role in resetting the punch assembly 4-2, and also plays a role in buffering and protecting the punch 4-22, preventing the punch 4-22 from being damaged by a hard collision with the punch mounting seat 4-21 when moving downward.

[0087] The punch mounting seat 4-21 includes an angle seat 4-211 and a punch connecting plate 4-212. The punch connecting plate 4-212 is mounted on the angle seat 4-211, and a fine-tuning structure is provided on the punch connecting plate 4-212. A screw hole 4-213 is provided on the angle seat 4-211, and a long hole 4-214 is provided on the punch connecting plate 4-212. The long hole 4-214 corresponds to the upper and lower positions of the screw hole 4-213. A bolt passes through the long hole 4-214 and is inserted into the screw hole 4-213, which is used to position the punch connecting plate 4-212 on the angle seat 4-211. When the bolt is loosened, the punch connecting plate 4-212 can be moved forward and backward to adjust its position within the length range of the long hole 4-214, thereby realizing fine-tuning of the position of the punch connecting plate 4-212. Both sides of the punch connecting plate 4-212 extend downwardly through baffles 4-215, and the two baffles 4-215 are arranged on the outer sides of the corner seat 4-211, which can prevent the corner seat 4-211 from moving left and right, and play a role in limiting the position of the corner seat 4-211. The surface of the punch connecting plate 4-212 is recessed downwardly with a slot 4-216, one end of the elastic member 4-25 is inserted into the slot 4-216, and the other end of the elastic member 4-25 elastically abuts against the punch 4-22. The slot 4-216 can limit the position of the elastic member 4-25, and plays a limiting role.

The upper inner wall and the lower inner wall of the slot 4-221 are the upper limit and the lower limit respectively. The limit block 4-217 can be inserted into the slot 4-221. When the punch 4-22 moves downward, the slot 4-221 moves downward. When it moves to the moving distance, the limit block 4-217 abuts against the upper limit, thereby preventing the punch 4-22 from continuing to move downward. When the driving device 4-23 releases the restriction on the punch 4-22, the punch 4-22 moves upward under the elastic force of the elastic member 4-25 and makes the limit block 4-217 abut against the lower limit, thereby preventing the punch 4-22 from moving upward excessively. The outer side surface of the punch 4-22 is provided with a groove 4-222, which is vertically arranged. The upper surface of the punch connecting plate 4-212 is fixedly connected with a guide block 4-218, which protrudes into the groove 4-222. When the punch 4-22 moves up and down, due to the cooperation between the guide block 4-218 and the groove 4-222, the punch 4-22 will not shake left and right during the movement. The cooperation between the guide block 4-218 and the groove 4-222 plays a guiding role. The bottom of the punch mounting seat 4-21 is fixedly connected with a pressure pad 4-219, which is provided with a hole for facilitating the insertion of the punch 4-22. The pressure pad 4-219 is provided to protect the corner seat 4-211 of the punch mounting seat 4-21, and prevent the corner seat 4-211 from directly hitting the structure below when the punch assembly 4-2 moves downward, causing structural damage.

A transfer groove 7-12 is provided to prevent the transfer transmission belt 7-21 from shaking on the transfer support plate 7-11, and also facilitate the movement of the finished workpiece in the transfer groove 7-12, and prevent the finished workpiece from detaching from the transfer transmission belt 7-21 during the movement. The transfer groove 7-12 plays a role of limiting. The driving motor 7-25 and the driving wheel 7-22 in this embodiment are respectively located on the two sides of the transfer frame 7-1, which can balance the overall transfer frame 7-1 and prevent the transfer frame 7-1 from tilting due to excessive weight on one side.

[0092] The tensioning assembly 7-3 includes a sliding block 7-31 and a tensioning wheel 7-32. The transfer base 7-1 is provided with a transfer through hole 7-16 for facilitating the movement of the sliding block 7-31 therein (the moving direction is along the length direction of the transfer base 7-1).
