Description

Technical Field

[0001] The utility model relates to the field of circular saw processing devices, in particular to a circular saw processing raw material clamping and positioning mechanism. Background Art

[0002] Saw blades are a general term for thin circular tools used to cut solid materials. Saw blades can be divided into: diamond saw blades for stone cutting, high-speed steel saw blades for metal material cutting, and carbide saw blades for cutting solid wood, fixtures, artificial boards, etc. The reason why saw blades can cut high-strength materials is because of their own high hardness and the existence of their teeth. Therefore, the saw blades need to have their teeth polished during the production and processing process, and before polishing the teeth, the saw blades need to be stably clamped, which requires a fixture to achieve. The fixture is a process device used to quickly tighten the workpiece during processing to keep the machine tool, tool, and workpiece in the correct relative position. The fixture is an indispensable component of mechanical processing. It ensures the processing accuracy of the workpiece, stabilizes the product quality, and is conducive to improving labor productivity and reducing costs.

[0003] The existing clamping devices for saw blade production still have certain shortcomings. The existing clamping devices generally use two clamping blocks to fix and clamp the saw blade. During the clamping process, the two clamping blocks may produce a certain shear force on the saw blade, causing damage to the saw blade. On the other hand, the clamping of the saw blade by the two clamping blocks may cause unstable factors, thereby interrupting the production of the saw blade and greatly reducing the processing efficiency.
