Universal lock for automobile machining process and mounting method thereof

Abstract

The invention relates to the field of automobile machining and manufacturing, in particular to a universal lock for the automobile machining process. The universal lock is used for assisting automobile machining and comprises a strip-shaped spring steel body, and at least one spiral structure is arranged in the middle of the spring steel body. One end of the spring steel body is provided with a conical body used for being in close fit with a door body lock hole of an automobile door, and the other end of the spring steel body is used for being inserted into a pin installation hole of an automobile door frame lock. After the two ends of the lock are mounted, the spiral structure elastically deforms. The invention further discloses a mounting method of the lock. According to the lock and themounting method thereof, mounting and dismounting are convenient, the universality is high, the three procedures of welding, electrophoresis and finish-paint coating can be achieved at the same time,the structure is simple, and the cost is low.

Description

technical field [0001] The application relates to the field of automobile processing and manufacturing, in particular to a general craft lock and an installation method thereof. Background technique [0002] In the process of automobile processing and manufacturing, the process lock is an indispensable tool. The process lock is mainly used to prevent the unexpected repeated opening and closing of the door when processing and manufacturing the car door or car body. It is mainly used in the welding process of the welding workshop, The electrophoresis process in the paint shop and the top coat process in the paint shop. In the painting workshop, the electrophoresis process has high requirements on the strength of the process lock. After the process lock relatively fixes the car door and the car body, the car door and the car body enter and exit the tank as a whole, and can withstand the impact of various liquids in the tank; In the welding workshop, the welding process does no...

AI Technical Summary

Problems solved by technology

In the painting workshop, the electrophoresis process has high requirements on the strength of the process lock. After the process lock is relatively fixed to the car door and the car body, the car door and the car body enter and exit the tank as a whole, and can withstand the impact of various liquids in the tank; In the welding workshop, the welding process does not have high requirements on the strength of the process lock, and the process lock is required to be as light and reliable as possible; in the painting workshop, the topcoat process requires that the process lock does not scratch the leaking parts of the door; due to the welding process, electrophoresis The focus of the process and the topcoat process are different. In the process of automobile processing, two to three different types of process locks need to be used, and the structure is more complicated and the cost is higher.
