AI Technical Summary

Technical Problem

During the manufacturing process of the inspection fixture, when there are a large number of inspection holes, the cumulative positional error between the holes can cause some holes to exceed the tolerance, resulting in the scrapping of the inspection fixture and making it difficult to meet the positional accuracy requirements.

Method used

An adjustable side inspection pin positioning fixture was designed. By setting a circular groove and an adjusting sleeve on the inspection platform, the axis position of the adjusting sleeve is determined by three-coordinate positioning. The position is finely adjusted by the tubular part of the adjusting sleeve in the movable space within the adjusting through hole. With the help of push-pull clamps and horizontal clamps, coarse and fine positioning are achieved, and machining errors are dynamically compensated.

Benefits of technology

It significantly improves the adaptability of the inspection fixture to machining errors, avoids the scrapping of the inspection platform due to insufficient accuracy, and improves clamping efficiency and positioning accuracy.

Abstract

The utility model discloses an adjustable side detection pin positioning gauge, which belongs to the technical field of detection and comprises a base, a supporting platform, a detection platform, an adjusting sleeve, a side detection pin and an adjusting sleeve positioning pin. A circular groove is formed in the side surface of the detection platform, and an adjusting through hole penetrating through the detection platform is formed in the bottom of the circular groove; the adjusting sleeve comprises a positioning part and a tubular part, the positioning part is of a disc-shaped structure, and a through hole is formed in the middle of the positioning part; the surface of the positioning part is provided with a screw mounting hole and a drilling pin hole, the tubular part is arranged on the positioning part, and the adjusting sleeve is provided with a through hole which penetrates through the positioning part and the tubular part and is used for a side detection pin to penetrate through; the positioning part of the adjusting sleeve is located in the circular groove of the detection platform, and the tubular part of the adjusting sleeve is located in the adjusting through hole of the detection platform; and a side detection pin is inserted into the adjusting sleeve. Through the arrangement, the technical problem that the whole detection platform of the detection tool is scrapped due to hole size deviation in the machining process of the detection tool is solved.
