AI Technical Summary

Technical Problem

Existing processing equipment for producing hexagonal flange nut assemblies often uses simple clamps for fixing, which makes it difficult to ensure that the nut is always in the center position during the tapping process. This leads to a decrease in tapping accuracy, inconsistent thread quality, and safety hazards such as tap damage and flying debris.

Method used

A processing device is adopted, which includes a base, a U-shaped frame, a hydraulic cylinder, an electric telescopic rod, a fixed seat, a drive motor, and a protective cover. The fixed seat and side rod are moved by the hydraulic cylinder and the electric telescopic rod, and the tap is rotated by the drive motor. Multiple wedge blocks and springs are used to fix the side wall of the nut to ensure that the center position of the nut does not deviate. At the same time, the protective cover provides protection during the tapping process.

Benefits of technology

It improves the accuracy and safety of tapping, reduces the risk of tap damage and chip splashing, lowers production costs and processing time, and enhances operational safety.

Abstract

The utility model relates to the technical field of flange nut machining, in particular to a machining device for hexagonal flange nut assembly production, which comprises a base, a U-shaped frame fixedly mounted at the upper end of the base, cross-shaped grooves formed in the side walls of the two sides of the U-shaped frame, and a hydraulic oil cylinder fixedly mounted at the upper end of the U-shaped frame. An electric telescopic rod is installed at the output end of the hydraulic oil cylinder, a fixing seat is fixedly installed at the lower end of the electric telescopic rod, sliding grooves are symmetrically formed in the fixing seat, side rods are fixedly installed on the side walls of the two sides of the fixing seat, a placing frame is fixedly installed at the upper end of the base, and a circular groove and an inner groove are formed in the upper end of the placing frame; the sliding frames are evenly and slidably installed in the inner wall of the inner groove at equal intervals, the wedge-shaped blocks are fixedly installed at the opposite ends of the sliding frames, the second springs are fixedly installed on the sliding frames, and through the mode that the wedge-shaped blocks are fixed towards the middle, the hexagonal flange nut can be always kept in the center position when placed and is not prone to deviation; and the tapping accuracy and effect are enhanced.
