Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1-4, a reversing switch fixing plate locking mechanism includes a workbench 1, a processing table 11 is arranged on the workbench 1, a workpiece groove 12 is arranged on the processing table 11, and the locking mechanism includes a limiting block 2, a pre-folding block 3 and a forming block 4, the limiting block 2 is slidably arranged on the front side of the workpiece groove 12, a slot 21 is arranged at the tail of the limiting block 2, a driving block 22 is arranged in the slot 21, the driving block 22 is driven by a first cylinder 23 to slide, a curve groove 24 is arranged on the driving block 22, a first connecting shaft 25 is slidably arranged in the curve groove 24, the first connecting shaft 25 is fixed in the slot 21, the pre-folding block 3 is slidably arranged on the left side and the right side of the workpiece groove 12, the pre-folding block 3 is driven by a second cylinder 31 to slide, the forming block 4 is slidably arranged on the rear side of the workpiece groove 12, run through on the workstation 1 and set up connecting rod 5, connecting rod 5 is connected with the pivot of workstation 1, the both ends of connecting rod 5 set up waist type hole 51, and it sets up second connecting axle 52 to slide in the waist type hole 51 of upper end, second connecting axle 52 is fixed in the afterbody of shaping piece 4, and it sets up third connecting axle 53 to slide in the waist type hole 51 of lower extreme, third connecting axle 53 drive connection is on third cylinder 54.

Preferably, a fixed seat 13 is arranged at the joint of the workbench 1 and the connecting rod 5, and the connecting rod 5 is connected to the fixed seat 13 in a rotating manner.

Further, the third connecting shaft 53 is fixed to a connecting block 55, and the connecting block 55 is fixed to a driving end of the third cylinder 54.

Further, a fixing plate 14 is arranged on the workbench 1 corresponding to the outer side of the connecting rod 5, a limiting bolt 15 penetrates through the fixing plate 14, and the limiting bolt 15 abuts against the outer wall of the connecting rod 5.

When the reversing switch fixing plate locking mechanism is used for locking and processing, a metal cover plate workpiece is placed in the workpiece groove 12, and the locking mechanism arranged on the metal cover plate workpiece is used for carrying out one-time locking and forming processing between two processes.

After the metal cover plate is placed in the middle of the workpiece groove 12, the first cylinder 23 is started to control the driving block 22 to slide left and right, and along with the sliding of the driving block 22, the first connecting shaft 25 slides synchronously in the curved groove 24 on the driving block 22, and due to the curved path of the curved groove 24, the first connecting shaft 25 drives the limiting block 2 which is fixedly connected with the first connecting shaft to slide back and forth, so that the head of the metal cover plate placed in the workpiece groove 12 is placed and limited.

And then, the second air cylinder 31 is started to control the pre-folding blocks 3 on the two sides to synchronously advance, so that the metal sheets on the left side and the right side of the metal cover plate after the metal cover plate is placed at the limit position are pressed and locked in the first process. Then, the third cylinder 54 is started to push the connecting block 55 at the driving end to extend back and forth, so that the third connecting shaft 53 on the connecting block 55 slides in the path of the kidney-shaped hole 51 at the lower end of the connecting rod 5, and the third connecting shaft 53 moves in the kidney-shaped hole 51 at the lower end of the connecting rod 5, so that the connecting rod 5 can be pushed to swing around the position of the connecting point of the middle part of the connecting rod and the rotating shaft of the fixed seat 13. When the connecting rod 5 swings, the second connecting shaft 52 in the waist-shaped hole 51 at the upper end of the connecting rod slides in the path synchronously, and then the forming block 4 fixedly connected with the connecting rod is driven to move forwards on the workpiece groove 12, so that the forming lock catch processing of the end part of the metal cover plate placed in the workpiece groove 12 is realized, and the second processing procedure is further completed. Finally, the reversing switch of the locked metal cover plate can be taken out only by controlling the sliding reset of the limiting block 2, the pre-folding block 3 and the forming block 4.
