Grooving and cutting tool and clamping assembly

Abstract

The invention discloses a grooving and cutting tool and a clamping assembly. The tool is put into the deformation hole of the knife plate through the clamping tool, and the user rotates the clamping tool. The cooperation between the clamping tool and the deformation hole makes the tip The elastic deformation reaches the open state, and the tool is put into or removed from the tool holder to achieve the effect of quick replacement, reduce the wear of the tool installation, and prolong the service life.

Description

technical field [0001] The invention belongs to the field of material processing, and in particular relates to a grooving and cutting tool clamping assembly. Background technique [0002] In metal turning, the workpiece is usually clamped on the machine tool and rotated around the central axis of the machine tool, and the cutting blade is fed along the radial direction of the machine tool to turn deep and narrow grooves on the workpiece or cut off the workpiece. When grooving, the cutting blade needs to be inserted into the workpiece at an appropriate depth to form a groove. At this time, the thickness of the cutting blade is the width of the groove. When cutting, not only the cutting blade needs to be inserted into the workpiece, but also the cutting blade needs to be inserted into the workpiece. near the central axis. The expensive cutting blade is clamped on the cutting blade, in this case, the thickness of the cutting blade is required to be smaller than that of the cut...

AI Technical Summary

Problems solved by technology

The expensive cutting blade is clamped on the cutting blade, in this case, the thickness of the cutting blade is required to be smaller than that of the cutting blade, otherwise, the cutting blade will interfere with the groove formed by the cutting blade, destroying the groove

However, the current clamping method of the grooving and cutting tool has many defects. For example, US5803675 discloses a turning tool with a self-tensioning clamping finger, which has the following defects: 1. When changing the blade, it is easy to get stuck and become 2. It is difficult to maintain the clamping device in the open state, and it is easy to shift the matching position, resulting in the inability to successfully complete the insertion or removal of the tool; 3. The transformation of the deformation area into plastic deformation rather than elastic deformation is obvious. Risk, which in turn leads to damage to the tool or fixture; 4. The wear and tear between the various parts is severe, resulting in a short service life
