AI Technical Summary

Technical Problem

During the machining of the tooth profile on the end face of the square plate, existing technologies make it difficult to quickly detect whether the tooth profile is qualified, resulting in low production efficiency and easy scrapping. In particular, it is difficult to detect tooth deformation and misalignment caused by insecure fixing or vibration in a timely manner.

Method used

A rapid inspection fixture was designed, comprising a clamping body, a chuck, an inspection tooling, and bolts. The tooth profile conformity is quickly determined by the meshing of the correction teeth and the end face teeth. The stability and accurate positioning of the square plate during the machining process are ensured by the cooperation of the correction shaft and the positioning pin.

Benefits of technology

It enables rapid detection of the tooth profile on the end face of the square plate, improving production efficiency, reducing production costs, and decreasing the scrap rate due to defective products.

Description

Technical Field

[0001] This utility model belongs to the field of inspection tooling, specifically relating to a rapid inspection tooling for the tooth profile of a square plate end face. Background Technology

[0002] The square plate is an important connecting part. One end of the square plate has end face teeth, and the tooth profile, shape, and positional accuracy of the end face teeth are subject to high requirements. When machining the end face teeth, an indexing instrument with a chuck is required. After machining each tooth profile, it needs to be rotated by a certain angle and then the machining is repeated. During the machining process, because the square plate is small and long, if it is not firmly fixed, it is very easy for the square plate to tilt, causing an angle between the axis of the machined end face teeth and the axis of the square plate. If the angle is too large, it is very easy to scrap the plate. During the machining process, the square plate is prone to vibration under the action of the cutting tool. Because the teeth of the end face teeth are small, if the vibration is too large, it is easy to deform the teeth and cause scrap.

[0003] During the processing of square plates, defective or misaligned teeth can cause scrap, which is difficult to detect from the appearance of the product. In the current technology, all the products are usually sent to the testing department for testing, which is slow and wastes manpower and resources. Utility Model Content

After the inspection fixture is flipped over, it is installed on the upper end of the square plate. The calibration shaft of the inspection fixture is inserted into the first center hole, the positioning pin is inserted into the positioning hole, and the calibration tooth meshes with the end face tooth.

[0007] The clamp body includes an upper clamp seat and a lower fixing shaft; the clamp seat has a second central hole at its center, a first groove on its upper surface, and a plurality of first threaded holes evenly distributed on the bottom surface of the first groove; the clamp seat has a positioning hole on its upper surface; the first shaft of the square plate is inserted into the second central hole, and the lower surface of the flange contacts the bottom surface of the first groove; the bolt passes through the first through hole and is installed in the first threaded hole; the fixing shaft of the clamp body is mounted on the chuck.
