[0023] See also Figure 1-4 A hinge rivet screw rivet device includes a frame 1, a top plate 2 fixedly connected to the top of the frame 1, and a power unit 3 detachably installed on the left side of the top of the top plate 2, the power unit 3 being a hydraulic cylinder.

[0024] Specifically, an insertion interface 4 is provided on the top left side of the top plate 2, and the bottom of the power device 3 passes through the insertion interface 4 and extends to the outside of the insertion interface 4. The power device 3 and the insertion interface 4 are movably connected.

[0025] In practical implementation, the front and rear sides of the power unit 3 are fixedly connected with fixed plates 5. The bottom of the fixed plate 5 is in movable contact with the top of the top plate 2. The bottom of the fixed plate 5 is provided with a limit port 6. The limit port 6 is movably engaged with a limit block 8. The bottom of the limit block 8 is fixedly connected with the bottom of the top plate 2. The right side of the fixed plate 5 is provided with a slot 9. The slot 9 is engaged with a left and right movable block 10.

[0026] Specifically, the right side of the card block 10 passes through the card slot 9 and extends to the outside of the card slot 9. The right ends of the two card blocks 10 are fixedly connected to the same connecting plate 11, and the bottom of the connecting plate 11 is in contact with the top of the top plate 2.

[0027] In practice, a threaded rod 12 is rotatably connected to the right side of the connecting plate 11, and a handle 13 is fixedly connected to the right end of the threaded rod 12.

[0028] Specifically, the surface of the threaded rod 12 is threadedly connected to a threaded sleeve 14, and the bottom of the threaded sleeve 14 is fixedly connected to the top of the top plate 2.

[0029] In practical implementation, the telescopic end of the power unit 3 is fixedly connected to the upper punch 15, the bottom of the frame 1 is fixedly connected to the base plate 16, and the left side of the frame 1 is fixedly connected to the support platform 17. The support platform 17 is equipped with the lower punch 18 and the hinge positioning fixture 19 for positioning and supporting the hinge. The specific structure and working principle of the upper punch 15, the lower punch 18 and the hinge positioning fixture 19 are the same as those of the patent with application number CN201921597717.3, and will not be elaborated here. When pressing the hinge with screws, first place the hinge on the hinge positioning fixture 19, align the holes for pressing the screws with the upper punch 15 and the lower punch 18, install the rivets, and then start the power unit 3 to drive the upper punch 15 to move up and down to perform the riveting.

[0030] In practical applications: When it is necessary to disassemble the power unit 3, simply rotate the handle 13 counterclockwise to drive the threaded rod 12 to rotate counterclockwise. Under the action of the thread, the threaded rod 12 moves to the right within the threaded sleeve 14, thereby driving the connecting plate 11 and the locking block 10 to move to the right. This causes the locking block 10 to disengage from the slot 9. Then, pull the power unit 3 upward, which in turn drives the fixing plate 5 upward, causing the limiting block 8 to disengage from the limiting port 6 and the power unit 3 to disengage from the insertion interface 4. Thus, the power unit 3 can be removed for maintenance. Through the above steps, the power unit 3 can be easily disassembled for maintenance. The operation is simple, time-saving, and labor-saving, without the need for any tools.
