Detailed Description

Referring to fig. 1 and 3, the riveting device for the printer part comprises an upper die 10, a lower die 20 and a jig 30 capable of being positioned on the lower die, wherein the jig comprises a lower plate 31, an upper plate 32 positioned on the lower plate, a positioning column positioning hole is formed in the lower plate, a positioning column perforation 321 is formed in the upper plate, a positioning structure is arranged between the upper plate and the lower plate, a lifting rod perforation is formed in the lower die 20, and a lifting rod 40 capable of lifting is matched in the lifting rod perforation.

In actual operation, the operator positions the positioning post 50 to be riveted in the positioning post positioning hole of the lower plate 31, and then the operator positions the upper plate 32 on the lower plate 31 through the positioning structure, and the positioning post 50 passes through the positioning post through hole 321. Then, the operator positions the side plate 51 of the printer on the upper plate 32, and the rivet holes on the side plate of the printer are aligned up and down with the positioning posts 50, at which time the top ends of the positioning posts 50 do not protrude upward from the side plate 51 of the printer. Then, the operator positions the jig 30 on the lower die 20, and the lifting rod 40 is lifted up to lift the positioning column 50 in the jig 30, so that the positioning column 50 protrudes upward from the side plate 51 of the printer. Then, the upper die 10 is lowered, and the rivet head 11 on the upper die rivets the positioning column 50 to the side plate 51 of the printer.

The positioning structure for positioning the upper layer plate 32 and the lower layer plate 31 can be a positioning pin and a positioning hole which are matched with each other, or can be a bolt and a screw hole which are matched with each other. For example, the lower layer plate 31 is provided with positioning pins, and the upper layer plate 32 is provided with positioning holes matched with the positioning pins; or, the upper plate 32 and the lower plate 31 are provided with corresponding screw holes, and bolts are screwed in the screw holes to combine the upper plate 32 and the lower plate 31.

The side plate 51 of the printer is positioned on the upper plate 32 through positioning pins, the positioning pins are arranged on the upper plate 32, and corresponding positioning holes on the side plate of the printer are matched with the positioning pins on the upper plate 32, so that the side plate 51 of the printer is positioned on the upper plate 32.

The operator positions the side plate 51 of the printer on the upper plate 32, and the riveting holes on the side plate of the printer are aligned up and down with the positioning posts 50, at this time, the top ends of the positioning posts 50 do not protrude upward from the side plate 51 of the printer, and the operation of the positioning posts 50 protruding upward from the side plate of the printer is completed by the lifting bars 40. As such, the size of the positioning posts 50 protruding upward from the printer side plate is controlled by the lift bar 40 to accommodate positioning posts of different lengths. In addition, when the operator positions the side plate 51 of the printer on the upper plate 32, the cooperation of the riveting hole site and the positioning column 50 is not required to be considered, so that the quick positioning of the side plate of the printer is facilitated.

As shown in fig. 4, the lower die 20 is provided with a left positioning structure 21, a right positioning structure 22 and a front positioning structure 23, and the rear part of the jig 30 is provided with a handle 33. Thus, after the jig completes positioning the positioning column 50 and the side plate 51 of the printer, the handle 33 can be gripped to position the jig in the left positioning structure 21, the right positioning structure 22, and the front positioning structure 23 of the lower die 20. After the riveting is finished, an operator holds the handle 33 to take out the jig 30 from the left positioning structure 21, the right positioning structure 22 and the front positioning structure 23, so that the riveting device is very convenient and is beneficial to improving the efficiency.

The left positioning structure 21 comprises a left positioning groove 211, the right positioning structure 22 comprises a right positioning groove 221, the left-right width of the upper layer plate 32 is smaller than the left-right width of the lower layer plate 31, the left edge of the lower layer plate can be matched in the left positioning groove, the right edge of the lower layer plate can be matched in the right positioning groove, and the handle 33 is arranged on the lower layer plate 31. The operator holds the handle 33 and horizontally inserts the jig 30 into the left positioning groove 211 and the right positioning groove 221, the front end of the jig 30 is stopped at the front positioning structure 23, and the front positioning structure 23 is provided with two limiting posts, as shown in fig. 2.

As shown in fig. 1, the lifting rod 40 is mounted on a lifting plate 41, which is connected to the piston rod of an air cylinder 42, and which is located below the lower die 20. After the jig 30 is positioned on the lower die 20, the lifting rod 40 is aligned with the positioning column 50 up and down, the air cylinder 42 drives the lifting plate 41 to lift, and the lifting plate drives the lifting rod 40 to lift so as to lift the positioning column 50. Then, the upper die 10 is lowered, and the rivet 11 rivets the top of the positioning column 50 to the side plate 51 of the printer. The lifting bar 40 is lowered to reset before the jig needs to be removed from the lower die 20.

The foregoing is merely illustrative of the preferred embodiments of the present utility model, and modifications in detail will readily occur to those skilled in the art based on the teachings herein without departing from the spirit and scope of the utility model.
