In the manufacture of the car can not be separated from the fixture, but the traditional fixture has been unable to meet the needs of automobile manufacturing, and for this manufacturers to produce a car welding fixture. Simply put, the automotive welding fixture is a kind of process device designed to meet the assembly of welding parts. The main function is to ensure that the welding element can meet the design relative position tolerance and geometric tolerance before and after assembling welding to ensure final assembly After the assembly accuracy. So how do you know the role of the car welding fixture? Here to do a detailed introduction.
1, to replace the mechanical parts of the manual parts of the positioning, clamping and workpiece flip and other heavy work to improve the working conditions of workers.
2, to ensure assembly accuracy, welding fixture itself has sufficient strength and stiffness, to control the workpiece in the assembly, tightening, welding deformation process. Parts positioning and positioner is designed according to the characteristics of welding parts, positioning and clamping mechanism to maintain the precise positioning of the components to prevent the parts in the assembly and welding process due to force and flip and shift. At the same time welding fixture accurate and reliable positioning and clamping, can reduce or even cancel the crossed work, with the equipment to replace the manual operation, reducing the probability of product deviation, improve the accuracy of parts and interchangeability. To avoid the use of artificial methods to control the tolerance caused by the accuracy, to ensure that the final group of welding parts manufacturing accuracy.
3, accurate and reliable positioning and clamping, can reduce or even cancel the cutting and crossed work. Reduce the size of the product deviation, improve the accuracy of parts and interchangeability.
4, so that the workpiece in the best welding parts, weld forming a good, significantly reduce the process defects, welding speed can be improved.
5, to reduce the labor intensity, to ensure safe production, in the workshop if the manufacturing can be used with the welding parts to match the structure of the car welding fixture, it can achieve rapid positioning of the workpiece, easy to install, with tooling equipment instead of artificial control manufacturing tolerance , Thus reducing the welding parts assembly and tightening the heavy manual labor, saving a lot of labor, reducing the labor intensity of the operator. At the same time the application of welding fixture to the operation of workers to form a flow of operations, each operator basically fixed in a certain area to complete the required work, is conducive to the production of automobile manufacturing workshop safety management.
6, effectively prevent and reduce the welding deformation.
7, to ensure the quality of welding, in the manufacture of welding fixture if the use of assembly welding, coupled with a reasonable design of the welding process and welding sequence, you can ensure that the exact relative position of the parts, effectively prevent and reduce the workpiece welding deformation The Especially in the production workshop batch equipment production, the use of fixtures can make the workpiece in the best welding parts, so that the welding position is stable and reliable, to ensure that welding workers stable welding quality, the weld shape is good, the process defects significantly reduced, At the same time welding speed can be improved to reduce the welding size deviation, to ensure product interchangeability, reducing the auxiliary work after welding to ensure the quality of welding.
8, can expand the scope of the use of advanced technology to promote the production of welded mechanization and automation of the comprehensive development.
9, to improve labor productivity and reduce production costs, automotive welding fixture can simplify each positioning, fixed work, greatly shorten the production process, reduce the use of artificial quantity, improve production efficiency, while the use of welding fixture also reduced the Assembly, welding workers to meet the technical requirements of the welding quality, reduce the welding after the deformation and repair process, simplifying the inspection process, shortening the entire product production cycle, significantly reduce the production costs, to create a certain business The economic benefits.
