Large-scale high-precision gear compound grinding center

Abstract

The invention provides a large-scale high-precision gear compound grinding center. The external gear grinding function module is arranged on the right side of the rotary table, including a bed, a column, a grinding wheel frame, a grinding wheel dressing device, an external gear grinding device, and on-machine measurement. Device; the internal gear, internal hole and end surface grinding functional modules are arranged on the left side of the rotary table, including the bed, column, internal hole and end surface grinding device, and internal tooth grinding device. The invention realizes one-time clamping of large gears, completes the grinding and precision detection of tooth surfaces, inner holes and end faces, and solves the difficulties of lifting, clamping, calibration and detection of large gears, as well as high processing costs, low production efficiency and difficult precision. The problem of guarantee greatly reduces the auxiliary time between processes, reduces the number of machine tools and fixtures, shortens the processing cycle, saves the operating area, significantly improves economic benefits, and completely changes the traditional processing of producing large gears with multiple large machine tools and gear gauges Way.

Description

technical field [0001] The invention belongs to the technical field of numerical control machine tools, and in particular relates to a large-scale, high-precision numerical control gear compound grinding machine tool. Background technique [0002] For emerging industries such as marine resource development equipment, large ships, high-speed locomotives, wind power, nuclear power, and aerospace that are currently being vigorously developed, large, high-precision hard-toothed gears are key power transmission components in these heavy machinery transmission industries. Large-scale, high-precision hard-tooth surface gear processing routes are mostly processed by hobbing, milling, gear shaping, etc. After the gear teeth are processed, heat treatment is performed to increase the hardness and then the tooth surface, inner hole, end surface, and internal tooth grinding are performed. , and finally perform precision testing on a large gear gauge. These processes require multiple lar...
