Geometric tolerance process for ensuring machining precision of servo motor end cover

Abstract

The invention discloses a geometric tolerance process for ensuring the machining precision of a servo motor end cover. The geometric tolerance process comprises the following steps that (1), 3D modeling on a servo motor end cover forge piece and a die is carried out by using Pro / EWildfire 2.0; (2), process numerical simulation is carried out by utilizing DEFORM-3Dv6.1, so that forming process parameters tend to be optimized; (3), a size relation graph is established according to the machining procedure of the servo motor end cover through the obtained forming process parameters; (4), a processsize chain is established through the size relation graph; and (5), solving the process size chain is carried out, and the geometric tolerance of the servo motor end cover is obtained. According to the geometric tolerance process for ensuring the machining precision of the servo motor end cover, the machining efficiency and the machining precision are improved, the quality of the servo motor endcover is improved, the production period is shortened, the production cost is reduced, the economical efficiency of a whole product is improved, and the application prospect is wide.

Description

technical field [0001] The invention belongs to the technical field of end cover processing technology, and in particular relates to a form and position tolerance process for ensuring the processing accuracy of a servo motor end cover. Background technique [0002] With the development of the machinery industry, the precision requirements for parts are getting higher and higher when processing mechanical parts. Since the accuracy of the whole machine and components is related to the accuracy of its parts, and the accuracy of the parts is related to the processing procedures of the parts, it is of great significance to study the accuracy of each processing process of the parts to improve the accuracy of the parts. [0003] When processing the surface of mechanical parts, there will be dimensional errors and shape errors, and the existence of these errors will affect the interchangeability of parts. At the same time, during the assembly process of parts, dimensional errors wi...
