Problems solved by technology

Among other things, such vibrations can damage the tool holder or the tool
The vibration phenomenon of the tool holder during processing is roughly proportional to the length of the tool holder. The lengthened elongated tool holder or the combined connection type disclosed in patent cases such as USP1502528, USP2716030 and USP8821084 Tool holder, because of the rigidity of the material of the tool holder, it is difficult to maintain sufficient rigidity, which makes the vibration of the tool holder and the tool more serious

Abstract

The invention provides a tool holder with an internal rigid retaining device, which is used in a processing machine with a mandrel. The tool holder comprises a handle part, a tool erection part, and at least one rigid retaining sleeve, wherein the handle part has a conical outer surface accommodated in the mandrel and a handle part male joint end part; the tool erection part comprises an axially extending tool erection aperture which can accommodate and fix a tool chuck, and the tool erection part is also provided with an erection part female joint end part matched with the handle part male joint end part; and the at least one rigid retaining sleeve is made of a high-rigidity material and is provided with a sleeve female joint end part and a sleeve male joint end part, so that the handle part, the rigid retaining sleeve and the tool erection part can be connected in series end to end.

Description

technical field [0001] The invention relates to a tool holder, in particular to a tool holder with an internal rigid holding device. Background technique [0002] At present, high-precision metal processing, such as drilling, milling, reaming, boring, internal and external diameter cutting or surface grinding, often uses computer numerical control (Computer Numerical Control, referred to as CNC) processing machines, such as drills, milling cutters and other tools for processing. These tools all have a long handle-shaped structure, and a tool holder is connected with the main shaft of the CNC processing machine table, and the main shaft can rotate at high speed, driving the tool held by the tool holder to rotate at high speed, The target workpiece is processed. [0003] Tool holders installed on processing machines tend to vibrate during use. Such vibration disturbs the process and has an adverse effect on product accuracy. In practice, vibrations are always generated whe...
