- 專用鏜床夾具設(shè)計(jì)Tool fixture machining process is an important component of the system is an important mechanical manufacturing technology and equipment. Tool fixture in machining plays an important role, which directly affect machining quality, productivity and production costs and labor intensity and so on. Therefore, the design of jigs and fixtures machining process is an important work in preparation.
Dedicated fixture design, based mainly on the connecting rod design task, the pump's installation jig boring machine has been designed with complete fixture with the positioning of parts, pieces of guidance documents on the knife, guidance documents and other parts used in fixtures design, and conducted a three-dimensional modeling with Soidworks. Fixture design, based on the design of the workpiece shape and processing requirements, design a suitable fixture. Taking into account the shape of a larger pump, it should be in the selection of the positioning fixture used parts bearing plates, and connecting rod workpiece size smaller, but higher precision.
This fixture was designed to basically meet the engineering needs of the design used in this method can also be designed for similar reference fixture.
