Embodiment

[0076] Such as Figure 1 to Figure 8 As shown, a large-scale, high-precision gear compound grinding center adopts a vertical structure and a symmetrical layout. The rotary table 1 is installed on the adjustment pad iron and connected with the foundation through anchor bolts. The external gear grinding function module is arranged on the right side of the rotary table, including bed 2, column 3, grinding wheel frame 4, grinding wheel dressing device 5, external gear grinding device 6, on-machine measuring device 7; internal gear, inner hole and The end face grinding function module is arranged on the left side of the rotary table, including bed 2, column 3, internal tooth grinding device 11, inner hole and end face grinding device 8. The large-scale, high-precision gear compound grinding center also includes an electrostatic mist absorption system 15, a grinding oil cooling and filtering system 16, and a machine tool safety system 17. This layout method has a compact structure...

Abstract

The invention provides a large high-accuracy gear composite grinding center. An outer tooth grinding function module is arranged on the right of a rotation work table and comprises a tool body, a column, a grinding wheel frame, a grinding wheel dressing unit, an outer tooth grinding unit and an on-machine measuring unit. An inner tooth, inner hole and end grinding function module is arranged on the left of the rotation work table and comprises a tool body, a column, an inner hole and end grinding unit and an inner tooth grinding unit. By means of the grinding center, one-step clamping of large gears is achieved, the tooth face, inner hole and end grinding and accuracy detection are completed; the problems that large gears are difficult to hoist, clamp, correct and detect, the machining cost is high, the production efficiency is low, the accuracy is hard to guarantee are solved; assisting time among processes is shortened greatly, the number of tools and clamps is reduced, the machining period is shortened, the operation area is saved, the economic benefit is improved apparently, and the traditional machining mode of large gear production through a plurality of large tools and gear measuring instruments is changed completely.

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...
