Abstract

The invention discloses a riveting pin clamp for a lock tongue cover plate. The riveting pin clamp for the lock tongue cover plate comprises a base plate, air cylinder fixing plates, air cylinders, air cylinder connecting shafts, floating connectors, punch fixing blocks and pre-pressing blocks. The air cylinder connecting shafts, the floating connectors, the punch fixing blocks and punches are sequentially driven through the air cylinders. The punches move in second through holes, so that compression springs are compressed, and the pre-pressing blocks press a workpiece under the compression of the compression springs; the punches push elastic cylindrical pins at the same time, the elastic cylindrical pins are compressed through the second through holes of the pre-pressing blocks to be riveted into the workpiece easily, and the air cylinders return to be in the initial state after the elastic cylindrical pins are in place. According to the riveting pin clamp for the lock tongue cover plate, the four elastic cylindrical pins can be riveted at a time, and riveting efficiency is greatly improved; in addition, the air cylinders are used for providing power, and machining safety is greatly improved. Furthermore, by additionally arranging pressing plates, positioning shafts and the pre-pressing blocks, it is guaranteed that the lock tongue cover plate is stable and free of shaking in the riveting process, and the riveting quality is greatly improved.

Example Embodiment

[0020] Example,
[0021] Please also refer to Figures 2 to 3 , a riveting pin clamp for a bolt cover plate, including a bottom plate 1, a cylinder fixing plate 2, a cylinder 3, a cylinder connecting shaft 4, a floating joint 5, a punch fixing block 6 and a pre-pressing block 7.
[0022] Among them, a positioning block 12 is provided at the center of the bottom plate 1 , and a cavity for arranging the lock tongue cover is provided on the positioning block 12 , a guide plate 17 is also provided between the positioning block 12 and the bottom plate 1 , and the lower part of the positioning block 12 is provided with The above-mentioned positioning block 12 can move on the guide plate 17 through the groove matched with the guide plate 17 . A vertical plate 13 is fixed on the bottom plate 1 near the rear side of the positioning block 12 . The vertical plate 13 is provided with a shaped hole, a positioning shaft 14 is installed in the shaped hole, and a pressure plate 15 is also fixed above the vertical plate 13 .
[0023] The outer side of the punch fixing block 6 is screwed with the floating joint 5, the nut end of the cylinder connecting shaft 4 is stuck in the T-shaped groove of the floating joint 5, the cylinder 3 is connected with the cylinder connecting shaft 4, and the cylinder 3 is fixed on the cylinder fixing plate 2 and a reinforcing rib 18 is provided at the connection between the cylinder fixing plate 2 and the bottom plate 1 .
[0024] The inner side of the cylinder fixing plate 2 is also symmetrically provided with a guide block 8, the guide block 8 is provided with a through groove, and two sides of the through groove are provided with guide grooves, and the punch fixing block 6 can move left and right in the guide groove.
[0025] The punch fixing block 6 is provided with two first countersunk holes and a first through hole, and the pre-pressing block 7 is correspondingly provided with two second through holes and a second countersunk hole. The first counterbore is equipped with a punch 9, and the punch 9 passes through the second through hole of the pre-compression block. The outer circumference of the punch 9 is provided with a step, and one end of the punch 9 is sleeved with the step, and the other is connected to the step. A compression spring 10 whose one end is in contact with the pre-compression block 7 . A pull rod 11 is provided between the second counterbore of the pre-compression block 7 and the first through hole of the punch fixing block 6 , and the pull rod 11 is in an interference fit with the pre-compression block 7 and the punch fixing block 6 . A mounting hole 16 for arranging an elastic cylindrical pin is provided at a position above the pre-pressing block 7 corresponding to the second through hole.
[0026] When the workpiece is processed, first put the workpiece into the cavity of the positioning block, slide it to the processing area through the guide plate, and press the workpiece in cooperation with the positioning shaft and the pressure plate. Then place the elastic cylindrical pin into the mounting hole on the preload. After completing this step, start the switch with both hands, and drive the cylinder connecting shaft, floating joint, punch fixing block, and punch in turn through the operation of the cylinder. The pre-compression block compresses the workpiece under the compression of the compression spring. At the same time, the punch pushes the elastic cylindrical pin and compresses it into the lock tongue cover through the second through hole of the pre-compression block. After it is in place, the cylinder returns to the initial position. Take the workpiece out of the processing area, and finally take the piece to complete the riveting process.
