Universal clamp for car door

Abstract

The invention discloses a universal clamp for a car door. The universal clamp comprises a fixed clamp, a clamp rod and a first positioning rod, wherein a spring is arranged at a hinged position of two clamp bodies of the fixed clamp; the clamp rod and the first positioning rod are fixed at upper parts of the clamp bodies on two sides of the fixed clamp respectively and are arranged relatively, and a clamping opening is formed between end parts of the clamp rod and the first positioning rod; a positioning clamping groove for positioning the edge of the car door is formed in the top of the clamp rod; and a positioning pin adaptive to a positioning hole in the car door is formed in the top of the first positioning rod. According to the universal clamp for the car door, disclosed by the invention, the distance between the positioning clamping groove and the positioning pin can be adjusted according to different car types, so that the clamp can be universally used for heavy-duty trucks and light-duty trucks; the investment cost of the clamp is saved and the cost is reduced; the working amount generated in a process of switching the clamp when the car types are switched is avoided, the probability of causing faults is reduced and the production efficiency is improved; and the clamp is simple in structure and convenient to mount and dismount.

Description

technical field [0001] The invention relates to a clamp, in particular to a universal clamp for car doors used for painting and spraying of automobiles. Background technique [0002] In the process of body painting, in order to protect the body, many tools are used, and one of the indispensable tools is the door clamp. The door clamp can be used to ensure that the door is not opened by external force to avoid the door being bruised; at the same time, the door clamp can also fix the door at an appropriate opening to ensure that the coated door does not contact the door frame and avoid coated The paint film is damaged, thereby avoiding unnecessary rework and improving the quality of body painting. The door fixture runs through the whole process of car body painting, from pretreatment to car body spraying, inspection and modification before disassembly, and plays an important role in the production process of car painting. [0003] Usually, in order to save costs, two models ...

AI Technical Summary

Problems solved by technology

Since the existing light truck and heavy truck door fixtures cannot be used in common, two kinds of door fixtures must be produced, which is costly; when light trucks and heavy trucks are switched in production, the door fixtures also need to be switched, which not only increases the workload of operators, increases Increased production costs, but also prone to errors, reducing production efficiency
