Comprehensive grinding machine tool based on middle clamping and rotating driving

Abstract

The invention discloses a comprehensive grinding machine tool based on middle clamping and rotating driving. The comprehensive grinding machine tool comprises a numerical control system and a hydraulic system and further comprises a static pressure middle clamping and rotating driving mechanism arranged on a machine tool bed. The two sides of the static pressure middle clamping and rotating driving mechanism are provided with inner circle grinding mechanisms and / or outer circle grinding mechanisms and centre mechanisms. The middle clamping and rotating driving mechanism comprises a machine base fixedly connected with the machine tool bed, and a high-precision static pressure rotating disc driven by a servo motor is arranged on the machine base. The rotating disc is connected with a drive wheel through a belt, the drive wheel is connected with an output shaft of the servo drive motor, and a rotating disc installation seat is provided with a static pressure oil inlet and a static pressure oil outlet. By means of the comprehensive grinding machine tool based on middle grinding and rotating driving, inner holes and outer circles of the left side and the right side of a machined part can be ground at the same time during one-time clamping, and therefore the high-precision coaxiality requirement is ensured; and the production efficiency is high, the machining precision is high, the machining cost of enterprises can be reduced, and the equipment investment is reduced.

Description

technical field [0001] The invention belongs to the technical field of machine tools, and relates to a comprehensive grinding machine tool based on intermediate clamping and rotating drive. Background technique [0002] In the case that the inner holes at both ends, outer circles at both ends or single-end outer circles on the same workpiece need to be ground, not only the grinding precision is high, but also the coaxiality after grinding is very high. The processing technology is performed by two internal grinding machines and one external grinding machine. The two internal grinding machines process the inner holes at both ends of the workpiece respectively, and then the outer circle of the workpiece is processed by an external grinding machine. A grinding machine is used to complete the grinding of the entire workpiece. For high-precision and mass-produced production enterprises, this kind of processing method is not only difficult to guarantee the accuracy and coaxiality...

AI Technical Summary

Problems solved by technology

For high-precision and mass-produced production enterprises, this kind of processing method is not only difficult to guarantee the accuracy and coaxiality of multiple clamping products, but also has low processing efficiency, scattered processes, and a large number of equipment covers a large area. The cost of personnel and other aspects will be very high, which will undoubtedly increase the cost of production for the enterprise, and the quality of the product will not be effectively controlled.
