It can be divided into two types according to the shape of the worktable: a rectangular worktable and a circular worktable. The surface grinder processing table is a device for processing surface grinder accessories. When processing on the production line, after the surface grinder grinds one plane of the workpiece, it is necessary to flip the workpiece 180° and grind the other surface.

The device can effectively solve the problem of automatic flipping of workpieces, and is particularly suitable for the problem of simultaneous processing and flipping of multiple small-sized workpieces. It is quick and easy to operate; it can be automated in conjunction with robots or other automated equipment.

When workpieces of different sizes need to be flipped, the workbench size of the device is fixed and may not be able to adapt to the size of the workpiece, reducing the practicality of the device.

[0029] A clamping mechanism, which is arranged on two side plates 8 and is used to clamp the placement plate 5;

[0030] A pushing mechanism, which is arranged on the clamping mechanism and is used to push the placement plate 5;

[0031] The adjusting mechanism is arranged on the bottom plate 1 to facilitate the replacement of the placing plate 5 .

[0032] The above technical scheme, through the clamping mechanism, the pushing mechanism and the adjusting mechanism, under the action of the No. 1 motor 3, the clamping mechanism and the pushing mechanism, the placement plate 5 is located between the two L-shaped frames 4. When the device flips the workpiece, the stability of the device is ensured, the vibration of the device is reduced, and the damage to the connection of the device is reduced, thereby extending the service life of the device. At the same time, when workpieces of different sizes need to be processed, the device can be easily adjusted to match workpieces of different sizes, thereby expanding the scope of use of the device and improving the practicability of the device.

[0033] Reference Figure 1-Figure 3 The clamping mechanism includes two bottom columns 9, four No. 2 motors 10, four U-shaped plates 7 and four No. 2 bidirectional screw rods 11. The tops of the two bottom columns 9 are fixedly connected to the bottoms of the two side plates 8, respectively. The bottoms of the four No. 2 motors 10 are fixedly connected to No. 1 blocks, one side of the four No. 1 blocks are fixedly connected to the two ends of the two bottom columns 9, respectively.

[0037] Reference Figure 1 The adjustment mechanism includes a No. 1 bidirectional screw rod 2 arranged on the top of the base plate 1. A rectangular groove is opened on the top of the base plate 1. The two ends of the No. 1 bidirectional screw rod 2 are rotatably connected to the inner walls of the two sides of the rectangular groove. Two rectangular blocks are threadedly connected to the No. 1 bidirectional screw rod 2. The tops of the two rectangular blocks are fixedly connected to the bottoms of the two L-shaped frames 4 respectively.

[0038] According to the above technical scheme, the handle is turned to drive the rotating plate 6 according to the size of the workpiece to be processed, and the rotating plate 6 drives the No. 1 bidirectional screw 2 to rotate, and the No. 1 bidirectional screw 2 drives the L-shaped frame 4 to move through the rectangular block. When the distance between the L-shaped frames 4 matches the size of the workpiece, the rotation is stopped. In this way, when workpieces of different sizes need to be processed, the device can be easily adjusted and then matched with workpieces of different sizes, thereby expanding the scope of use of the device and improving the practicality of the device.
