Milling machine for machining small-size part by adopting built-in multi-section pressurizing principle

Abstract

The invention discloses a milling machine for machining a small-size part by adopting a built-in multi-section pressurizing principle. The machine structurally comprises a controller, a main shaft vertical arm, a travel table, a heat dissipation groove, a numerical control host machine, a waste scrap pool, a machining table and a mechanical main shaft, wherein the heat dissipation groove is of a rectangular structure and is arranged on the right side of the numerical control host machine in an embedded mode. According to the machine, after being started, the mechanical main shaft drives a pressurizing assembly to press downward a double-station dispersing mechanism by driving the axis, when the double-station dispersing mechanism descends to a certain height, driving of a turning guide rail is matched, and stacking is performed, so that an inner supporting blade is driven to push out a blade head transverse nail in an outer covering blade, the two sides of a cutter bar is blocked and prevented, waste scraps generated by the cutter bar can be effectively removed, the situation that the cutter bar is heated and broken due to the fact that the waste scraps adhere to a cutter and are curled is avoided, and the service life of the cutter bar is prolonged.

Description

Technical field [0001] The invention relates to the field of milling machines, in particular to a milling machine for processing small-sized parts that adopts the principle of built-in multi-stage pressurization. Background technique [0002] Compared with CNC machine tools, milling machines are mainly used for parts with large machining accuracy limitations. With the continuous advancement of industrial technology, CNC programming milling machines will gradually replace manual operations, releasing labor in a large range, and requiring the ability of manual parts Also gradually improved, the main difference between CNC milling machines and CNC machine tools is different from the spindles used. Because of the relaxation of machining accuracy, milling machines generally adopt mechanical spindles to reduce production costs. The existing technologies on the market have such problems in the use process: [0003] Although the cutting accuracy of the current milling machine with mechani...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a milling machine for processing small-sized parts using the principle of built-in multi-stage pressurization, so as to solve the problem that although the cutting accuracy of the current milling machine using the mechanical spindle can be satisfied, the high speed of the mechanical spindle The diameter of the dynamic balance of the tool holder is relatively large, which directly leads to the inability to remove the waste generated by cutting, which is prone to sticking to the knife, resulting in the problem that the waste is accumulated and entangled on the tool holder and affects the processing.
