A gear milling machine tool

Abstract

The invention belongs to the field of gear machining and particularly relates to a gear milling machine tool. The gear milling machine tool comprises a gear milling machine tool body, a worktable, a fork-like tool carrier and a vertical turntable, wherein the vertical turntable is arranged at one end of the worktable; a center frame or a tailstock is arranged at the other end of the worktable and has the same axis as the vertical turntable; and the vertical turntable works together with the center frame or the tailstock to mount and clamp a shaft gear. The gear milling machine tool further comprises a horizontal turntable for mounting and clamping a disk gear, wherein the horizontal turntable is mounted on the worktable through a lifting device and arranged on the side, close to the gear milling machine tool body, of the worktable; the horizontal turntable adopts a circular truncated cone structure; and a mounting groove for mounting and clamping a clamp of the disk gear is formed in the horizontal turntable of the circular truncated cone structure along the axis from the central position of the top surface. The gear milling machine tool can be applied to processing of disk gears in various sizes and shaft gears in various sizes.

Description

technical field [0001] The invention belongs to the field of gear processing, in particular to a gear milling machine tool. Background technique [0002] The processing methods currently used for industrial cylindrical gears are mainly gear hobbing, gear shaping and gear grinding, which are respectively completed on gear hobbing machines, gear shaping machines and form grinding wheel gear grinding machines. The problem with these processing methods is that for gears with a large modulus, such as gears with a modulus greater than 25, especially gears with a relatively large helix angle, the processing efficiency of the traditional hobbing method is not high, and the efficiency of gear shaping is lower; When hobbing a gear with a large helix angle, there is a lot of vibration, and it is often necessary to feed in multiple times to achieve the required tooth depth; the cost of the hob is relatively high, and the corresponding hob needs to be ordered for each modulus of gear, an...

Problems solved by technology

The problem with these processing methods is that for gears with a large modulus, such as gears with a modulus greater than 25, especially gears with a relatively large helix angle, the processing efficiency of the traditional hobbing method is not high, and the efficiency of gear shaping is lower; When hobbing a gear with a large helix angle, there is a lot of vibration, and it is often necessary to feed in multiple times to achieve the required tooth depth; the cost of the hob is relatively high, and the corresponding hob needs to be ordered for each modulus of gear, and the order cycle is long; Knives and gear shaping cutters are usually damaged and cannot be repaired; grinding wheels for form grinding need to be modified according to each different workpiece. For industrial gears produced in small batches of a single piece, the dressing loss of the grinding wheel may be much greater than the grinding consumption of the grinding wheel , resulting in increased production costs and extended production preparation cycles; the initial investment of equipment is large, and the scope of application is small. Machine tools for processing cylindrical gears cannot process spiral bevel gears and straight bevel gears, and machine tools for processing disc gears usually cannot process gears with long shafts

But the technical problem is that once the machine tool design is completed, it can only be used for the processing of the same size disc gear or shaft gear, and the application range is small.
