Fixture refers to the device used to fix the processing object in the process of mechanical manufacturing, so that it occupies the correct position to accept construction or inspection, also known as fixture (qiǎ jǜ). In a broad sense, any process in the process, the device used to quickly, easily and safely install the workpiece can be called a fixture. What are the design suggestions for stamping hardware processing production clamps?
Most welding tooling is specially designed for the assembly and welding process of a certain welding assembly. It is a non-standard device and often needs to be designed and manufactured according to the characteristics of the product structure, 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 manufacturing industries such as automobiles, motorcycles, and aircraft, it is no exaggeration to say that there is no product without welding tooling. During the process design, the required type of tooling, structural sketches and brief descriptions are proposed, and on this basis, the detailed structure and parts design and all drawings are completed.
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, artistry, etc. must be considered when designing welding tooling.
Dimensional chain issues are prevalent in mechanical design and manufacturing. In the process of assembling the parts into a machine, that is, combining and accumulating the relevant dimensions on the parts. Due to the manufacturing error in the size of the parts, there will be a synthesis and accumulation of errors during assembly. The total error formed after accumulation will affect the working performance and quality of the machine. This forms the mutual influence relationship between the dimensional error of the part and the comprehensive error. Designing tooling fixtures is no exception. It is very important to reasonably determine the dimensional tolerances and geometric tolerances of parts.
Through the design of this course, it not only enhances the systematization of professional knowledge of welding process equipment, but also organically combines professional knowledge, design ability and practical ability. The deeper harvest should be to consolidate and broaden the idea of designing tooling fixtures and exercise the principle and flexibility of design thinking.
