Precision part machining numerical control machine tool

Abstract

The invention discloses a precision part machining numerical control machine tool. The precision part machining numerical control machine tool comprises a machining chamber with an inner cavity. A workpiece machining device and a workpiece fixing and rotating mechanism are arranged in the machining chamber. The workpiece machining device comprises a moving mechanism and a turret capable of being driven to move and rotate by the moving mechanism. A plurality of machining tools are arranged on the turret. Cutting edges of at least two of the machining tools have the height difference. At least part of the machining tools of which the cutting edges have the height difference are detachably connected with the turret through different lengths of tool aprons. According to the precision part machining numerical control machine tool, the machining tools are fixed to the turret through the tool aprons with the different lengths; the requirement for the low position of the cutting edges of the machining tools can be met through the tool aprons; and accordingly, the length of the machining tool can be greatly reduced to ensure the rigidity of the tools, and the machining stability and qualitycan be improved.

Description

technical field [0001] The invention relates to the field of machine tools, in particular to a numerically controlled machine tool for machining precision parts. Background technique [0002] CNC machine tool is the abbreviation of numerical control machine tool, which is an automatic machine tool equipped with a program control system. The control system can logically process programs with control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the numerical control device through the information carrier. After calculation and processing, various control signals are sent by the numerical control device to control the movement of the machine tool, and the parts are automatically processed according to the shape and size required by the drawing. [0003] Some CNC machine tools include a processing chamber, a workpiece fixing mechanism, a turret tool holder, a structure for driving the turret tool holder to move, a control...

Problems solved by technology

[0005] As disclosed in the application number 201820526251.7, a machine tool rotary tool holder device includes a rotary body and a structure for driving the rotary body to rotate. A set of cutter sleeves are arranged on the rotary body, and the lengths of the cutter sleeves are the same. In actual processing, the cutting edges of the cutters installed on the rotary body often need different heights to achieve continuous processing at different positions. Since the cutter sleeves are all of the same size, this requires the cutters to have different lengths. At this time The length of some tools needs to be set very long, resulting in a decrease in the rigidity of the tool, which greatly reduces the cutting stability and cutting quality
