With the popularity of the automobile, the modern automobile production line fully automated production lines, the production line more applications in the automotive welding equipment welding fixture. Automotive welding fixture weldment is to accurately locate and secure grip for easy assembly and welding weldment, weldment structure to ensure the accuracy requirements of the process equipment. So auto welding fixture overhaul how?
1, overhaul includes the following four points:
 
(1) whether the positioning pins are secure and bending deformation, pin wear amount is too large, the general positioning pins and the workpiece bore diameter of not more than 0.25mm. Positioning block is solid, the positioning surface wear is too large, generally not more than 0.3mm.
 
(2) whether reliable clamping pressure clamp, pressure head wear is serious, if the head is so small and easy to press out the work pits must be grinding or replacement.
 
(3) the connecting member bolts are tightened and reliable, at a fixed spot weld presence of cracks. There Chute positioning is reliable, whether to move freely.
 
(4) components for damage pneumatic clamps, cylinders and piping for leaks, the clamping mechanism is reliable and automotive welding fixture identification is clear.
 
2, the operator shall be accompanied by complete overhaul maintenance personnel to work together.
 
3, in addition to copper positioning pins, other steel dowel pins in the replacement must be heat treated to increase wear resistance. Drawings locating the heat treatment should also be heat treated at block replacement.
 
4, all hanging points and MIG welding fixture shall be installed every six months overhaul, maintenance records and fill.
 
Today automobile welding fixture overhaul how do you share here, in addition to having the above points beyond, in terms of production to achieve accelerated welding mechanization and automation processes, etc. also plays a very important role.
