The Rationality Of Auto Welding Jig

     Welding fixture is to ensure the size of welding parts, improve assembly accuracy and efficiency, prevent welding deformation of the fixture used. The requirements for the components of the welding fixture are: The positioning surface and the mating surface requirements are smooth, the parts with the use of pin positioning, fixture positioning generally using hole positioning and surface positioning, so the size and location of the hole should be accurate and reliable, in the design of parts should consider the process of NC machining and feasibility, shorten the programming time, improve production efficiency.Auto Welding Jig

     The part design should consider the clamping rationality, in the numerical control processing, should reduce the auxiliary man-hour as far as possible, cannot completely depend on to seek the positive to guarantee the processing accuracy, otherwise will multiply the workload. NC Machining uses simple tooling for positioning clamping, part design should be fully considered to facilitate the clamping, that is, large enough clamping surface, parts can be accurately positioned in machine tools or simple tooling, clamping should be convenient and reliable processing, on the one hand, to ensure that the parts after a number of times after the processing of the surface of the mutual position between the correctness.Auto Welding Jig

     On the other hand, once installed as far as possible to complete the parts on more surface processing, not easy to install the parts, can be considered in the parts to increase the process of convex table, process lug and other auxiliary benchmarks. As shown in Fig. 1, the workpiece is missing a suitable positioning datum, so two additional process lugs are added, and a locating datum hole is produced on the lug.Auto Welding Jig

    Welding fixture parts are characterized by a variety of parts and miscellaneous, but the number of single 10 pieces of processing less. Therefore, the structural design of parts, not only requires processing, but also easy to process, to improve production efficiency, to ensure processing quality, reduce costs.Auto Welding Jig

     To this end, you can consider the following aspects. Minimize clamping times. Too many clamping times, it is difficult to ensure the accuracy of the position of the processing surface, so it is best to process all processing surfaces in one clamping. To this end, a number of parts of the processing surface should be distributed as far as possible in one direction, so that can be processed in one clamping.Auto Welding Jig
