Technical Field

[0001] This application relates to the field of internal gear processing, and particularly to a gear processing device. Background Art

[0002] Internal gear milling uses a gear-shaped milling cutter to perform continuous rotary cutting on the inner wall of a workpiece (ring body), while the workpiece rotates synchronously, and internal teeth are machined by a generating motion or a forming method. An internal gear milling device is a special or modified machine tool system for machining precise internal teeth on the inner wall of an annular workpiece.

[0003] During the existing internal gear processing, due to the meshing action between the tool and the workpiece, a large amount of metal chips will be generated. These chips are likely to accumulate on the inner circumferential surface of the gear ring body, easily causing machining accuracy deviation and abnormal tool wear, and affecting the machining accuracy of internal gears. Summary of the Invention

[0004] In order to improve the machining accuracy of internal gears, this application provides a gear processing device.

[0005] A gear processing device provided by this application adopts the following technical solution: A gear processing device includes a box body, a fixed seat, a turntable and a clamping member. The box body is provided with a processing cavity. The fixed seat is fixedly connected to the bottom wall of the processing cavity. The turntable is rotatably connected to the upper end of the fixed seat around its own axis, and the rotation axis of the turntable is vertical.

The clamping member is used for clamping a workpiece to be processed. A chip removal groove is provided at the bottom of the positioning groove, and a chip removal port is provided on the outer wall of the turntable. The chip removal port communicates with the chip removal groove.

[0006] By adopting the above technical solution, the workpiece to be processed is embedded in the positioning groove. The positioning groove limits the workpiece to be processed. The rotation of the turntable drives the workpiece to be processed to rotate synchronously. Part of the chips generated during the machining of the internal teeth of the workpiece to be processed fall into the chip removal groove, and the centrifugal force generated by the rotation of the turntable causes the chips to be discharged from the chip removal port, reducing the probability of affecting the machining quality of the workpiece to be processed due to chip accumulation.

[0007] Preferably, the clamping member includes a clamping block and a pressing ring. The clamping block is slidably connected to the bottom of the positioning groove. The clamping block is used to abut against the workpiece to be processed.
