Device for detecting disc stationary fixture

Abstract

The invention relates to a device for detecting a disc stationary fixture. A round pin matched with a centre hole of the disc stationary fixture is mounted on the positive face of an operating platform; detecting devices for detecting directions at 30 degrees are arranged at the left side and the right side of the round pin, respectively; a detecting device for detecting a waist-shaped groove is mounted under the round pin; dowel pins matched with two circular holes on a left foot of the disc stationary fixture are symmetrically arranged below the left of the positive face of the operating platform; the dowel pins matched with two circular holes on a right foot of the disc stationary fixture are arranged below the right of the positive face of the operating platform; a hollowed structure is arranged on the operating platform and internally provided with a lifting platform device for supporting the disc stationary fixture. The device provided by the invention can quickly inspect the disc stationary fixture to ensure the quality of the final inspected product.

Description

technical field [0001] The invention relates to a device for detecting a disc fixing jig. Background technique [0002] The disc of the computer hard disk storage unit is the most important key core part of the hard disk industry, and the production of the disc is a fully automatic assembly line production. The disc needs to be fixed by fixed tooling during the production process to ensure that the position of the disc is consistent during the production process. To ensure the consistency of discs produced. The inspection tool is used to check whether the consistency of the fixed tool is qualified. It mainly uses projectors, height gauges, go-no-go gauges, etc. to measure. Since the positions to be measured are on different three-dimensional space surfaces, these detection methods cannot meet the requirements. The data cannot determine whether the relative position between the three-dimensional spaces is correct, and the instruments used for detection are different, and th...

The inspection tool is used to check whether the consistency of the fixed tool is qualified. It mainly uses projectors, height gauges, go-no-go gauges, etc. to measure. Since the positions to be measured are on different three-dimensional space surfaces, these detection methods cannot meet the requirements. The data cannot determine whether the relative position between the three-dimensional space is correct, the instruments used for detection are different, and the benchmarks for detection are also different

The operation is cumbersome, single measurement and other reasons are far from meeting the actual production and quality requirements, and batch production cannot be monitored effectively in real time
