Based on the general machine tool and fixture brackets after the design and development
Abstract: Bracket machine after machine is an important part, because of its smaller size components, structural shape is not very complicated complex. But because of its size precision, accuracy and geometry mutual positioning accuracy, and the surface quality of the surface have affected parts of the machine or assembly quality, thereby affecting its performance and working life, it is the design of processing is also a very crucial and important.
In the development process, can be divided into two parts, namely, process design and fixture design of the part. To identify the processes of the installation process and the need for further processing and the process of Locomotive Machine feed rate, depth of cut, and cutting speed spindle speed, the process of fixture, knives and measuring tools, and walk the knife cutting the number and length of the final calculation of the basic processes of the time, work time and support to serve time. Fixture for the design, bracket after boring lathe, milling, drilling processes for the use of the fixture, the characteristics of such fixture is targeted strong, compact, easy to operate, high productivity. Thus ensuring fixture easy to operate, reliable clamping, the use of safe and reasonable working space. The design will use books theoretical and practical requirements of the integration of the lathe after the completion of the processing order bracket design.
