Description

A CNC Grinding Blade Positioning and Clamping Mechanism

technical field

The utility model relates to the technical field of grinding blade clamping, in particular to a numerically controlled grinding blade positioning and clamping mechanism.

Background technique

When the existing grinding blade is positioned and clamped, it is directly clamped by the clip, and then the preset four bolts are rotated clockwise through the screw holes arranged on the clip, until the ends of the four bolts are in contact with the side wall surface of the grinding blade. Positioning and clamping can be achieved during extrusion, but this method requires the use of an Allen wrench and the constant rotation of each bolt.

In the patent whose publication number is CN209986762U, a kind of CNC peripheral grinding blade positioning and clamping device is proposed. The clamping arm, the second clamping arm, the pressing pad, the bayonet pin, and the spring rotate the clamping structure through the first screw rod and the second screw rod to realize the relatively convenient grinding of the blade body by the first clamping arm and the second clamping arm Quick positioning and clamping effectively improves the efficiency of positioning and clamping the grinding blade body. Through the bayonet clamping structure, the circular shifting block can be clamped and positioned, which effectively avoids the possibility of the circular shifting block’s rotation and greatly improves the The first clamping arm and the second clamping arm clamp the stability of the grinding blade body, but there are also the following problems in this patent:

Use two clamping arms to clamp the grinding blade. It is not easy to remove and use. It is easy to cause the grinding blade to not be positioned tightly during use and cause it to fall. It is easy to cause damage to the grinding blade and cannot be used again. It only depends on the pressing pad. Clamping it does not have a stable effect.
