Problems solved by technology

At present, there are mainly three methods for processing semicircular holes: ① Insert the semicircular hole first and then grind the semicircular hole with a high-precision inner hole gear grinding machine. Although the accuracy of this method can be guaranteed, the equipment used is relatively expensive and the processing efficiency is relatively low; ② .Milling the whole hole first, and then milling off the excess part. This processing method is easy to deform the semi-circular hole, but the precision is low; ③.Using wire cutting to process the semi-circular hole, this processing method has low processing efficiency and precision

Embodiment Construction

[0026] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that the embodiments are illustrative, not restrictive, and cannot limit the protection scope of the present invention.

[0027] In order to facilitate the understanding of this processing method, the device used in the processing process is first explained:

[0028] An internal gear processing device for a planetary cycloid reducer housing, including a base 12, a tensioning sleeve 11, and an open sleeve 13. The base includes a base 4, a circular table 10, and an annular table. The base is cylindrical as a whole, and its side wall A plurality of vertically arranged machine tool clamping grooves 6 are made, and the base can be installed on the machine tool through the machine tool clamping grooves. An L-shaped groove is made on the upper surface of the base, and the vertical limit of this L-shaped groove is to find the front 5 for i...

Abstract

The invention relates to a method and device for machining internal teeth of a planetary cycloidal pin gear reducer housing. A tool is installed on a vertical machining center, a workpiece is assembled on the tool, alignment of the tool is carried out, the tool is static after the workpiece is completely machined, and the workpiece is detached for machining a new workpiece. The invention further provides the method for machining the internal teeth of the planetary cycloidal pin gear reducer housing and a flexible device. When the method and device are used for machining the internal teeth of the planetary cycloidal pin gear reducer housing, machining of all pin tooth holes can be completed through one-time clamping, machining errors and assembly errors are reduced, the manufacturing accuracy is improved, the production speed is accelerated, and products meet the high precision requirements of reducers.

Description

technical field [0001] The invention relates to the machining of a planetary cycloid reducer in the technical field of mechanical processing, in particular to a method and device for processing inner teeth of a planetary cycloid reducer housing. Background technique [0002] As one of the four core technologies of industrial robots, the reducer occupies a large proportion in the production cost of industrial robots. As a new type of reduction transmission device, the planetary cycloid reducer has the characteristics of high rigidity, large transmission ratio, small static hysteresis and high dynamic transmission accuracy. The shell is the core part of the planetary cycloid reducer, and it is ring-shaped. The holes for installing pins in the shell are a series of holes with a small radius, a large aspect ratio, high precision, and a semicircular shape. At present, there are mainly three methods for processing semicircular holes: ① Insert the semicircular hole first and then ...
