AI Technical Summary

Technical Problem

The existing welding positioning device for the headrest skeleton of the car seat cannot flexibly adjust the spacing, resulting in the distance between the welding points and the fixed points being too close or covered, affecting the welding efficiency and quality.

Method used

A welding tool including a movable plate, a lifting cylinder, a positioning assembly and a clamping assembly is designed. Through the sliding connection between the movable plate and the countertop panel, the lifting cylinder drives the vertical movement of the connecting rod and the lifting plate, combining a rotating motor and an arc-shaped positioning block to achieve accurate positioning and stable clamping of head restraint skeletons of different shapes and sizes.

Benefits of technology

It improves the welding in placement rate and quality, enhances the versatility and adaptability of the tooling, prevents displacement and deformation during the welding process, and improves welding efficiency and stability.

Abstract

The utility model discloses an automobile seat headrest framework welding tool which comprises a base and a deck plate, and a movable plate is arranged above the deck plate. A mounting frame is arranged above the movable plate, and a lifting air cylinder is arranged at the rear end of the mounting frame; the lifting cylinder is movably connected with the connecting rod, the front end of the connecting rod is connected with a lifting plate, and a positioning assembly is arranged on the lifting plate; two clamping assemblies are symmetrically arranged on the two sides of the mounting frame. The movable plate is in sliding connection with the deck plate, and the lifting air cylinder drives the connecting rod and the lifting plate, so that the position of the positioning assembly can be flexibly adjusted according to the size of a framework, and the welding arrival rate and quality are improved; and by means of the design of the clamping assembly, it is ensured that welding parts of the headrest framework are stably clamped in the welding process, displacement and deformation in the welding process are prevented, the welding quality is further improved, and extremely high practicability and market popularization value are achieved.
