AI Technical Summary

Technical Problem

Traditional indexing plates have difficult vacuum chambers that are hard to clean and have poor adaptability, making them unsuitable for different sizes of testing equipment or parts to be tested, requiring the entire indexing plate to be replaced.

Method used

A suction-type indexing plate is designed, which adopts a detachable top cover and main plate structure. The test piece is fixed by negative pressure adsorption. The air passage semi-groove connects the negative pressure chamber and the suction hole, realizing multi-size adaptability and facilitating maintenance.

Benefits of technology

It improves the adaptability and maintenance convenience of the indexing plate, reduces material preparation costs and thickness, and enhances the versatility and reliability of the equipment.

Abstract

The utility model relates to an air suction type index plate and appearance detection equipment, a main plate is provided with an air passage semi-groove, a suction hole is communicated with a concave area through the air passage semi-groove, and a to-be-detected piece is adsorbed and fixed at an adsorption groove at negative pressure. For detection equipment or to-be-detected pieces of different specifications, only the main disc or the upper cover needs to be replaced independently, so that the adaptability of the air suction type index plate is improved, and the material preparation cost and the product universality are also reduced; the upper cover hermetically covers the concave area to serve as the negative pressure cavity, and the upper cover can be detached from the main disc, so that the negative pressure cavity is more convenient and thorough to maintain, and the problem that the negative pressure cavity is difficult to clean or incomplete to clean is solved; the upper cover, the main disc and even the whole air suction type index plate can be replaced by being disassembled above the upper cover, so that maintenance is easy; compared with a traditional through wall design, the design that the air passage semi-grooves are communicated with the negative pressure cavities and the suction holes facilitates reduction of the thickness of the main disc on the premise that the strength of the main disc is guaranteed, and therefore the thickness of the air suction type dividing disc is reduced.
