Milling and cutting machine tool for making toroidal worm

Abstract

The invention relates to the technical field of machine tools, in particular to a milling and cutting machine tool for making toroidal worms. The length direction of the front bed is fixed on the bed base along the Y direction; the spiral chip conveyor is arranged in the front bed along the Y direction; the main shaft of the machine tool is movably arranged at one end of the front bed along the Y direction; the tail The seat and the tailstock are movably arranged on the other end of the front bed along the Y direction; the whirlwind cutting part, the whirlwind cutting part includes a tool device, an upper moving table, a machine tool rotary drive device, and a base plate that are sequentially arranged from top to bottom. Device; the cutting tool device is arranged on the upper movable platform so as to be movable along the length direction of the front bed, and the upper movable platform is arranged on the rotary drive device of the machine tool so as to be movable along the width direction of the front bed. The tool imitating the worm gear of the present invention only needs to rotate a sector with a limited angle, and cancels the existing rotary table with full circle rotation. The occupied area of ​​the space is reduced.

Description

technical field [0001] The invention relates to the technical field of machine tools, in particular to a milling and cutting machine tool for making toroidal worms. Background technique [0002] The toroidal worm drive has the advantages of strong bearing capacity, high transmission efficiency, and long service life, and is a high-performance worm drive form. It has been a hundred years since it appeared in the United States in the form of a planar enveloping worm gear transmission at the beginning of the last century. In the 1970s, my country first used the quadratic planar enveloping worm gear drive in the world. After half a century of development, in addition to the plane envelope form, the single and double cone envelope, roller envelope, involute envelope and other toroidal worm gear transmission methods have also been researched and developed. [0003] The production of the toroidal worm and the guarantee and testing of its production accuracy have always been a hot...

AI Technical Summary

Problems solved by technology

It is necessary to have a large enough rotary table to withstand the cutting impact of the tool, but the machine tool structure of the large rotary table cannot accommodate it

Limited by the size of the rotary table, the existing machine tool structure is inevitably insufficient in rigidity

And although in principle, the adjustment of each component in place only requires the two-axis linkage between the tool rotation and the workpiece rotation to make the worm, but due to the limited structure, in order to meet the different center distance requirements of the workpiece, the machine tool often has to adopt 4-axis or 5-axis Axis linkage mode work

[0007] Although all the above-mentioned machine tool designs are numerically controlled, they have not clearly informed how to ensure the accuracy of each adjustment link.
