AI Technical Summary
Existing methods for inspecting the dimensions of machined parts holes are inefficient and prone to human error, making it difficult to meet the rapid inspection needs of mass production.
A rapid inspection fixture for machined parts was designed. It consists of a base, a positioning component, and an inspection component. Through the cooperation of the longitudinal positioning datum surface, the transverse positioning datum surface, and the inspection pin, it achieves rapid and accurate positioning and inspection, avoiding human error.
It improves testing efficiency, ensures testing accuracy, is suitable for mass production, reduces human error, is easy to operate, and is suitable for rapid testing on the production line.
