Therefore, whether in the machinery processing, assembly, testing, or in welding, heat treatment, such as cold, heat process, and transport are a lot of work in a fixture. But in machining is the most widely used metal-cutting machine tools for use on the fixture, we called for the machine tool fixture. It guarantees high-quality products, high-yield, low-cost, bring into full play the potential of existing equipment, so that workers have complicated or sophisticated parts processing technologies, to reduce the heavy physical labors, and other aspects play a huge role. Therefore, the fixture of the machine is designed to promote the production and use of the rapid development of one of the important process.</p><p>&nbsp; This article mainly revolves the engine bed drill hole jig design is a center. With drills the azimuth training gear shell, first let us through the visit practice have the preliminary understanding to the jig design, was specially more profound to the lap type jig jig design&#39;s understanding. Then, under teacher&#39;s instruction, carries on the analysis and the choice to the jig design proposal. After designating the plan. Through consult related jig design books and related chart of symbols in drill hole jig design process. After having consulted the related literature completes the foreign language translation.
