[0024] In the case implementation, a small motor 9 is fixedly installed on the inner side of the first connecting rod 7, and a groove matching the small motor 9 is opened on the inner side of the first connecting rod 7. A pressure plate 10 is arranged on the output shaft of the small motor 9, and a buffer pad is fixedly installed on the bottom of the pressure plate 10 to protect the top of the workpiece.

[0025] When implementing, follow these steps:

[0026] 1) First, push the positioning block 304 to move left and right. The left and right movement of the positioning block 304 drives the telescopic rod 303 to contract. The contraction of the telescopic rod 303 drives the first compression spring 302 to contract. The first compression spring 302 also applies an outward force to the positioning block 304.

[0027] 2) Then, the workpiece is placed on the top of the placement plate 307, and the positioning block 304 is loosened.

[0030] In summary, the clamping mechanism used in the rotary glass pinching machine first pushes the positioning block 304 to move left and right. The left and right movement of the positioning block 304 drives the telescopic rod 303 to contract. The contraction of the telescopic rod 303 drives the first compression spring 302 to contract. The first compression spring 302 also applies an outward force to the positioning block 304. Then, the workpiece is placed on the top of the placement plate 307, and the positioning block 304 is released. The first compression spring 302 applies an outward force to the positioning block 304 to fix the workpiece. The limit block 305 ensures the stability of the left and right movement of the positioning block 304, and then the electric push rod is started to drive the movable block 5 to move up and down. The movable block 5 moves up and down to drive the support table 12 to move up and down. At the same time, the fixed frame 4 also moves up and down. The fixed frame 4 moves up and down to drive the first connecting rod 7 to move up and down. The first connecting rod 7 moves up and down and then drives the pressure plate 10 to move up and down. Finally, the small motor 9 is started, and its output shaft rotates to drive the pressure plate 10 to rotate. The rotation of the pressure plate 10 drives the workpiece to rotate, so that the workpiece is heated and processed at multiple angles.
