Abstract
This design is the subject of gearbox top cover structure design, the processing technological process formulation and process equipment design. Replace parts of the complex structure, and mass production, in order to improve production efficiency and reduce labor intensity, specially designed for the special combined machine tool, fixture. The design specification can be divided into four parts:
The first part set box cover structure design, In the upper cover structure design, consider the box structure, reasonable selection box structure size, thickness of the box wall, hole size perspective.
The second part is technical regulations of the mechanical processing.In the development process, determine the installation position of each process and the process need the labor step, feed, machine tools and machining of the processes of the cutting depth, spindle speed, and cutting speed, the basic time finally calculated the procedures, work time and support to business hours.
The third part is the combination of machine tool design -- combination boring lathe. Better to increase productivity, improve processing accuracy, reduce production cost.
The four part is the design of special fixture. The use of special fixture can reduce the work labor intensity, improve labor productivity, and obtain high machining accuracy.
Keywords: box technology modular machine tool fixture
