Abstract
The design of machine tools for the universal valve Tingzhu spherical grinding machine, can achieve automatic grinding. Used to grind the surface of a small metallographic specimen. It is required to design the structure of the transmission chain and design the structural dimensions of the key components. It is required to design the work table of the machine tool and design the structure of the key parts. It is necessary to design the structure of the transmission chain and design the structure of the key parts. Size, requiring the design of the machine up and down grinding disc. Requires the design of the machine up and down the spindle. Drawing the main contents of the upper and lower grinding disc and spindle and other key parts and machine layout of the overall plan.
The valve is mounted mainly by the original power, gear drive, worm drive, workbench and other components. In view of the current problems in the design of the grinder, as well as the constraints of the actual conditions, the design of the project designed for: servo motor - gear drive - worm drive - table action. In this transmission scheme, the gear transmission capacity is higher, the transmission movement is accurate and smooth. Transmission power and a wide range of peripheral speed, high transmission efficiency, compact structure.
Key words: valve tappet, spherical grinder, drive design, structural design
