[0033] Example 2

[0034] On the basis of Example 1, the following further aspects are included:

[0035] like Figure 9As shown, the rotation locking device 06 includes a plurality of locking pieces 61 and a plurality of electric locks 62. The plurality of locking pieces 61 are fixedly mounted on the sides of the plurality of clamping claws 54, and the plurality of electric locks 62 are fixedly mounted on the sides of the plurality of brackets 55. The plurality of locking pieces 61 are respectively mounted in conjunction with the plurality of electric locks 62.

[0036] First, place the white corundum on the conveyor belt 15, and the conveyor belt 15 transports the white corundum. The white corundum is positioned and stopped at the positioning plate 24. Then, the cylinder 1 21 is turned on, and the cylinder 1 21 provides power to drive the push plate 1 23 to move back and forth. The push plate 1 23 moves backward to push the white corundum for loading. At the same time, the cylinder 3 41 is turned on, and the cylinder 3 41 provides power to drive the push plate 3 43 to move back and forth. The push plate 3 43 moves forward to position the white corundum. After positioning is completed, the push plates 1 23 and 3 43 are reset. Open the cylinder 2 31 and the cylinder 4 51. The cylinder 2 31 provides power to drive the push plate 2 33 to move left and right. The push plate 2 33 moves right to clamp the white corundum. The cylinder 4 51 provides power to drive the bracket 9 53 to move left and right. The movement of the bracket 9 53 drives the clamping claw 54 and the bracket 10 55 to move together. The spring expansion joint 56 provides spring elasticity to the bracket 10 55. When the bracket 9 53 moves to the left, the movement of the bracket 10 55 to the left is blocked, driving the clamping claw 54 to rotate along the bracket 9 53, so that the clamping claw 54 is moved from The horizontal state is converted to the vertical state. At this time, the clamping jaw 54 reaches the maximum rotation limit and continues to move to the left until the clamping jaw 54 contacts the white corundum and clamps the white corundum. When clamping, the electric lock 62 automatically locks the locking plate 61. The locked locking plate 61 limits the rotation of the clamping jaw 54, thereby preventing the clamping jaw 54 from rotating under force after contacting the white corundum and increasing the clamping force. When the clamping jaw 54 needs to rotate, the electric lock 62 automatically opens, allowing the locking plate 61 to move freely. After the processing is completed, open the cylinder 4 51. Cylinder four 51 provides power to drive bracket nine 53 to move left and right. When bracket nine 53 moves to the right, bracket ten 55 is blocked from moving to the right, driving the clamping jaw 54 to rotate along bracket nine 53, so that the clamping jaw 54 is converted from a vertical state to a horizontal state. At this time, the clamping jaw 54 reaches the maximum rotation limit and continues to move to the right, releasing the white corundum and making room for unloading. Then, cylinder two 31 is opened, and cylinder two 31 provides power to drive push plate two 33 to move left and right. Push plate two 33 continues to move right to unload the white corundum.

[0037] like Figures 1 to 9As shown, the present invention is a clamping device for processing white corundum. When working, the white corundum is first placed on the conveyor belt 15, and the conveyor belt 15 transports the white corundum. The white corundum is positioned and stopped at the positioning plate 24. Then, the cylinder 1 21 is turned on, and the cylinder 1 21 provides power to drive the push plate 1 23 to move back and forth. The push plate 1 23 moves backward to push the white corundum for loading. At the same time, the cylinder 3 41 is turned on, and the cylinder 3 41 provides power to drive the push plate 3 43 to move back and forth. The push plate 3 43 moves forward to position the white corundum. After positioning is completed, push plate 1 23 and push plate 3 43 are reset, and then cylinder 2 31 and cylinder 4 51 are turned on. Cylinder 2 31 provides power to drive push plate 2 33 to move left and right. Push plate 2 33 moves right to clamp the white corundum. Cylinder 4 51 provides power to drive bracket 9 53 to move left and right. The movement of bracket 9 53 drives the clamping claw 54 and bracket 10 55 to move together. The spring expansion joint 56 provides spring elastic force to bracket 10 55. When bracket 9 53 moves to the left, the movement of bracket 10 55 to the left is blocked, driving the clamping claw 54 along The bracket 9 53 rotates to convert the clamping jaw 54 from a horizontal state to a vertical state. At this time, the clamping jaw 54 reaches its maximum rotation limit and continues to move to the left until the clamping jaw 54 contacts the white corundum and clamps the white corundum. When clamping, the electric lock 62 automatically locks the locking piece 61. The locked locking piece 61 limits the rotation of the clamping jaw 54, thereby preventing the clamping jaw 54 from rotating under force after contacting the white corundum, thereby increasing the clamping force. When the clamping jaw 54 needs to be rotated, the electric lock 62 automatically opens to allow the locking piece 61 to move freely. After the processing is completed, the clamping jaw 54 is opened. Open cylinder four 51, cylinder four 51 provides power to drive bracket nine 53 to move left and right. When bracket nine 53 moves to the right, bracket ten 55 is blocked from moving to the right, driving the clamping jaw 54 to rotate along bracket nine 53, so that the clamping jaw 54 is converted from a vertical state to a horizontal state. At this time, the clamping jaw 54 reaches the maximum rotation limit and continues to move to the right, releasing the white corundum and making room for unloading. Then open cylinder two 31, cylinder two 31 provides power to drive push plate two 33 to move left and right. Push plate two 33 continues to move right to unload the white corundum.

[0038] The conveyor belt 15, cylinder 1 21, cylinder 2 31, cylinder 3 41, multiple cylinder 4s 51, multiple spring telescopic joints 56 and multiple electric locks 62 of the utility model are purchased on the market. Technicians in this industry only need to install and operate them according to the accompanying instruction manual, without the need for technical personnel in this field to make creative labor.

[0039] The main functions achieved by the present invention are: by arranging a loading device 02, a unloading device 03 and a positioning device 04, white corundum is automatically loaded and unloaded, thereby reducing the labor intensity of workers; and by arranging a unloading device 03 and a clamping device 05, white corundum is clamped, thereby improving the applicability of the machine; it solves the existing technical problems that workers are required to manually load and unload white corundum, which has high labor intensity, and the existing clamping mechanism is not easy to clamp white corundum sheets with irregular shapes, resulting in poor machine applicability.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
