Welding fixture is the accurate positioning of welding parts and reliable clamping, easy to assemble and weld parts, to ensure the accuracy of the structure of the process equipment. In modern welding production, actively promote and use the product structure to adapt to the fixture, to improve product quality, reduce labor intensity, speed welding production to achieve mechanization, automation process, etc. plays a very important role.Auto Welding Jig
In the welding production process, welding requires less work hours, and about 2/3 of the total processing time is used for preparation, assembly and other ancillary work, greatly affecting the production speed of welding. To this end, we must vigorously promote the use of mechanized and high degree of automation of assembly welding equipment.
The main functions of welding fixture are as follows: (1) accurate, reliable positioning and clamping, can reduce or even eliminate blanking and line work. Reduce the size deviation of the product, improve the precision and the change of the parts. (2) effectively prevent and reduce the welding deformation. (3) The workpiece is in the best welding position, the weld is well formed, the process defects are obviously reduced and the welding speed is improved. (4) The working conditions of the workers are improved by replacing the position, clamping and workpiece turnover of the manual assembly parts. (5) The use of advanced technology can be expanded to promote the comprehensive development of the production mechanization and automation of welded structures.Auto Welding Jig
The basic requirements of fixture design (1), fixture should have sufficient strength and stiffness. Fixture in the production of the use of a variety of efforts to withstand the role, so the fixture should have sufficient strength and stiffness. (2), clamping reliability. Clamping can not destroy the position of the workpiece location and ensure that the shape of the product and size to conform to the drawing requirements. It can not allow the workpiece to loose slip, and do not make the constraint of the workpiece through large, resulting in greater restraint stress. (3), the flexibility of welding operation. The use of fixture production should ensure adequate welding space, so that operators have a good vision and operating environment, so that the whole process of welding production in a stable working condition. (4) Facilitate the handling of welding parts. The operation should take into account products in the assembly positioning welding or welding can be smoothly removed from the fixture, but also products in the flip or suspension to make the damage. (5), good workmanship. The fixture should be designed to be easy to manufacture, install and operate, and easy to inspect, repair and replace vulnerable parts. The design should also consider the existing clamping power source, hoisting capacity and installation site and other factors, reduce fixture manufacturing costs.Auto Welding Jig
