Welding clamp for aviation chair handrail

Abstract

The invention provides a welding clamp for aviation chair handrail. The welding clamp for aviation chair handrail comprises a supporting block and a limiting block. One end of a base extends to form a pressing seat, a sliding groove is formed in the top of the pressing seat, and a sliding seat is movably assembled on the sliding groove. A pressing block is arranged at one end of the top of the sliding seat, a cam disc is arranged on the pressing seat at the other end of the sliding seat, and a control handle is arranged on the cam disc. The base is provided with the limiting block matched with the pressing block, the supporting block is arranged on one side of the limiting block, and a U-shaped clamping groove is formed in the top of the supporting block. A positioning block is arranged on one side of the supporting block, press pincers are arranged on one side of the positioning block, a pressing plate is arranged on a telescopic rod of the press pincers and provided with an inwards concaved arc surface, and the arc surface is located on one side of the positioning block. After the scheme is adopted, manual positioning is not needed, the welding effect is good, the size is accurate, a skewing phenomenon is avoided, the labor intensity of workers is greatly relieved, and the quality of products is improved.

Description

technical field [0001] The invention relates to the technical field of chair production, in particular to an aviation chair armrest welding fixture. Background technique [0002] The seat is an indispensable part of the facilities in the aircraft cabin. It provides the occupants in the cabin with work and life guarantees and protection from damage. In addition to providing passengers with the most satisfactory travel comfort and working conditions, the seat should also protect the passengers from injury as much as possible when the aircraft makes an emergency landing. Especially the various injuries to the occupants caused when the seat assembly is damaged due to the forced landing of the aircraft. With the continuous development of aircraft technology and in order to better protect the safety of passengers, the airworthiness authorities of various countries in the world have put forward perfect and strict requirements for aircraft seats, so the chairs must be accurately po...

AI Technical Summary

Problems solved by technology

With the continuous development of aircraft technology and in order to better protect the safety of passengers, the airworthiness authorities of various countries in the world have put forward perfect and strict requirements for aircraft seats, so the chairs must be accurately positioned and sized during production. During the production and processing process of the seat back frame, several processed parts are welded together one by one. After welding, the processing error is large, the size is difficult to guarantee, and the processing time is long and the work efficiency is low.
