Special Fixture Design and Precision Measurement of Automobile Flange Fork

Abstract

Because of structural features and batch job requirements in automotive manufacturing line of automotive flange fork parts, the high requirement about its parts is made in the aspect of four positioning datum hole position degrees. Therefore, it is necessary to consider special fixture when designing and processing its parts to make sure batch production, and precision measurement to ensure product quality. In the actual processing, three generations of special fixtures for processing and production use are designed to make improvement for processing and contrasting, through the process of design, trial processing, size adjustment, fixture precision measure and adjustment. Special fixture size precision adjustment is completed, through modern precision measurement equipment using three-dimensional coordinate measurement, to satisfy the parts processing quality and requirements. At present, this production technology has reference significance to a certain extent in the manufacturing process of automotive fork similar products.
