Design of Fast Switch Fixture in Processing Center

Abstract

This paper analyzes background and significance of the research on the design of switched machining parts in processing center, briefly introduces the development of the relevant jig assembly design theory and technology at home and abroad, and introduces, analyzes and compares the toggle assembly technology of the toggle processing center of small and medium-sized enterprises. In order to solve the problem of the working efficiency of the machining center in switching machining parts, the design adopted in the design is to use the working principle of jig assembly. The design characteristics, overall structure and working principle of the design are introduced in detail., the present situation of the processing center is improved and innovated, the corresponding process flow is changed according to the actual working conditions, and the corresponding fixture data is calculated and checked according to the actual situation. And the structure characteristics of the fixture assembly are introduced. At the same time, the detailed design and analysis of the important parts and components are completed.

Key words: processing centre; Fixture assembly; Design; working efficiency
