AI Technical Summary

Technical Problem

Existing steering wheel fixing fixtures are difficult to adapt to the steering shaft connection hole sizes of different vehicle models, resulting in frequent replacement of the support head and reducing the efficiency of steering wheel grinding.

Method used

A fixture including a variable diameter support head seat and a segmented elastic support head is designed. Through the cooperation of the wedge groove and the support claw, it can be adapted to different steering shaft connection holes. The elastic support head is driven by a cylinder to slide in the wedge groove, and the support claw expands outward and tightens in the steering shaft connection hole of the steering wheel.

Benefits of technology

There is no need to stop the machine to replace the support head when changing car models, which significantly improves the efficiency of steering wheel grinding and achieves efficient fixation of steering wheels for different car models.

Abstract

This utility model relates to the field of steering wheel polishing, and more particularly to a steering wheel fixing fixture, including a robotic arm mounting base, which is fixedly mounted on the end of the robotic arm; a fixture base plate, which is fixedly mounted on the robotic arm mounting base; a cylinder, which is fixedly mounted on the fixture base plate; a support plate, which is located at the telescopic end of the cylinder and fixedly mounted on the end face of the cylinder body; a support head seat, which is fixedly mounted on the support plate and has a variable diameter structure; an elastic support head, which has a split structure; and a connecting rod, which passes through the support head seat and the support plate. One end of the connecting rod is connected to the telescopic end of the cylinder, and the other end of the connecting rod is fixedly connected to the elastic support head. When the cylinder drives the elastic support head to move towards the support head seat, the elastic support head slides along the axial direction of the support head seat and expands outward, tightening within the steering shaft connection hole of the steering wheel. This utility model eliminates the need to replace the support head when polishing the steering wheel, significantly improving the efficiency of steering wheel polishing.
