ENGLISHSteps
(1) Assemble the two parts of the engine 4 liner into the sequence 1 strut according to the "strut welding combination" diagram, and place it on the clamp concrete. The retaining pin and the baffle will position the sequence 1 strut by The screw clamp clamps the sequence 1 strut; at the same time, the two parts of the sequence 4 engine liner are positioned by the bolt, and are clamped by the quick-retracting screw clamping device;
(2) After the point welding, loosen the quick-retracting screw clamping device, pull out the bolt, and remove it for welding;
(3) placing the weldment on the clamp, positioning the weldment by the stop pin and the baffle, and clamping the weldment by the screw clamp; then placing the component of the nut M6 and the horn support on the weldment and Positioned by the screw clamping mechanism by the taper pin on the screw clamping mechanism and the open groove on the pressure plate of the screw clamping mechanism;
(4) Three-sided welding of the nut M6 and the horn support assembly and the struts, and then loosening all the screw clamps, and the clamping plates of the screw clamping mechanism of the clamping nut M6 and the horn bearing assembly are spring-loaded. The positioning cone pin on the same is disengaged from the weldment, and then the pressure plate is pushed out to disengage one end from the screw of the screw clamping mechanism, and the pressure plate is rotated to the side of the weldment, and then the weldment is taken out.
Design suggestion
Most welding fixtures are specially designed for the assembly welding process of certain welding assemblies. They are non-standard devices and often need to be designed and manufactured according to the characteristics of the product, production conditions and your actual needs. Welding tooling design is one of the important contents of production preparation and one of the main tasks of welding production process design. For the manufacturing industries such as automobiles, motorcycles and airplanes, it is no exaggeration to say that there is no product without welding tools. Through the process design, the required tooling type, structural sketch and brief description are put forward, and the detailed structure and part design and all the drawings are completed on this basis.
The quality of tooling design has a direct impact on production efficiency, processing cost, product quality and production safety. For this reason, practicality, economy, reliability, and artistry must be considered when designing welding tools.
Dimensional chain problems are common in mechanical design and manufacturing processes. In the process of assembling parts into machines, that is, combining and accumulating the relevant dimensions on the parts. Due to manufacturing errors in the size of the part, there is a synthesis and accumulation of errors during assembly. The total error formed after accumulation will affect the performance and quality of the machine. This creates an interaction between the dimensional error of the part and the integrated error. Design fixtures are no exception. It is important to reasonably determine the dimensional tolerances and geometric tolerances of the part.
Through this course design, it not only enhances the systematicization of the professional knowledge of welding process equipment, but also combines the professional knowledge, design ability and practical ability organically. The deeper harvest should be to consolidate and broaden the thinking of design fixtures and the exercise of the principle of thinking and flexibility of the design.
