Abstract
This article is based on the analysis of the fork parts and processing technology of CA6140 lathe, including the analysis of the part drawing of CA6140 fork, the selection of the blank, the formulation of the fixture, the process route of the parts, the selection of the cutter, and the determination of the cutting method to fill the number of process documents. Choose the right processing method and design the processing technology reasonably. In addition, a special fixture is designed for the filling cover of two process parts.
Many types of jigs, jigs, amongwhich the mostwidely used general purpose jigs, sizes and more standardized, aswell as specialized factory production. It iswidely used in large-scale production, and is suitable for the special fixture ofworkpiece processing flow service. You need to design and manufacture theworkpiece processed inyour own factory. The main content of this paper is to design and process fixture to design bearing hole fixture.
Keywords: CA6140 lathe, treatment, processing method, process document
