Description

Technical Field

[0001] The invention belongs to the technical field of clamping mechanisms, and in particular relates to a pneumatic gear rack linked rotating clamping mechanism. Background Art

[0002] When processing both sides of the long side at the same time, the existing sheet products can only be fixed by negative pressure adsorption (because the side to be processed needs to give way, only the front and back ends and the middle part have operating space). However, negative pressure has high requirements on the cleanliness of the contact surface between the workpiece and the product, and the existing products need to add water to cool the processing surface during grinding. The working conditions are relatively poor and the cleanliness of the contact surface cannot be ensured (there is sewage and grinding chips). In addition, during the processing process, the negative pressure will fail when it is subjected to a force perpendicular to the direction of the negative pressure (when subjected to a force perpendicular to the direction of the negative pressure, the product will slide or be lifted, and once the vacuum leaks, it will cause the product to fall).

[0003] In view of this, we propose a pneumatic gear rack linkage rotating clamping mechanism. Summary of the invention
