Description

Technical Field

[0001] This utility model relates to the field of process product testing technology, specifically a perpendicularity testing fixture. Background Technology

[0002] In the production and manufacturing of craft products, product inspection directly affects product quality. Shape, size, and structure are important indicators of whether a product is qualified or not. Various inspection tools are needed to inspect these parameters. The tools that can be used to inspect parameters are collectively called inspection tools. For important product parameters, more complex inspection methods or specially made inspection tools are often required for measurement.

[0003] Currently, most products on the market require high-precision and complex tools for perpendicularity testing. These tools are cumbersome to operate, have high technical requirements, are inefficient, and have large errors, making it difficult to perform accurate, fast, and efficient testing. In addition, for a simple product, perpendicularity testing may require taking into account different surfaces, angles, and the complex structure of the product, necessitating repeated measurements. Therefore, we propose a perpendicularity testing fixture that can be adjusted to different angles. Utility Model Content
