Abstract
The invention relates to a cutter handle structure of a high-speed cutter, in particular to the field of high-speed machining cutters. The cutter handle structure comprises a cutter handle body and acollet chuck; the cutter handle body comprises a first-stage matching section and a second-stage matching section which are connected, the first-stage matching section is in a cone shape, a cone corner of the first-stage matching section is arranged far away from the direction of the second-stage matching section, and a matching hole is formed in the surface, far away from the first-stage matchingsection, of the second-stage matching section; the collet chuck is arranged in the matching hole, the matching hole is an inner cone hole, and the small bottom face of the matching hole is arranged close to the first-stage matching section; and the collet chuck is in a cone shape, the outer surface of the collet chuck is attached to the side face of the inner wall of the matching hole, and the matching hole and the collet chuck are arranged in a wedge clamping mode. The invention further relates to a manufacturing process of the cutter handle structure of the high-speed cutter. The manufacturing process comprises the steps of rough machining, first finish machining of the cutter handle body, primary machining of the matching hole and secondary finish machining of the cutter handle body. The cutter handle structure of the high-speed cutter has the effect of improving the connecting stability between the cutter handle body and the collet chuck.
Description
technical field [0001] The present application relates to the field of high-speed machining tools, in particular to a handle structure of a high-speed tool and a manufacturing process thereof. Background technique [0002] At present, the development of high-speed machining technology provides an important guarantee for the development and application of high-speed machining machine tools. At the same time, high-speed cutting technology also puts forward various new requirements for machine tools. Compared with traditional CNC machine tools, high-speed machining machine tools have undergone major changes in structure and performance. system, high-speed machining monitoring system and auxiliary system, etc. Among them, the high-speed tool system refers to the connection system between the machine tool spindle and the tool. [0003] The high-speed tool system in the related art generally includes a spindle, a tool holder, a clamping mechanism and a tool. The clamping mechani...
