[0005] Since the helical non-circular gear has a large diameter and a thin thickness, the helical non-circular gear is fixed only by a limit seat and a turntable. The helical non-circular gear is easy to rotate relative to the turntable during the processing, resulting in low precision of the helical non-circular gear. Summary of the invention

[0006] In order to reduce the rotation of the helical non-circular gear relative to the turntable during the machining process and improve the precision of the helical non-circular gear, the present application provides a gear shaping machine for machining the helical non-circular gear.

[0007] The present application provides a gear shaping machine for machining helical non-circular gears, which adopts the following technical solution:

[0008] A gear shaping machine for processing helical non-circular gears, comprising a frame, a turntable, a positioning assembly, a clamping assembly, a rotating assembly for driving the turntable to rotate, and a gear shaping assembly, wherein the turntable is rotatably connected to the frame, the positioning assembly comprises a clamping block and a plurality of top columns, the clamping block is arranged on the turntable, the clamping block is used to engage with the flared opening of the helical non-circular gear, the top column is arranged on the turntable, the plurality of top columns correspond to a plurality of mounting holes of the helical non-circular gear one by one, the top column passes through the mounting hole, and the clamping assembly is used to press the helical non-circular gear against the turntable.

[0009] By adopting the above technical solution, the staff first places the helical non-circular gear on the turntable, clamps it with the helical non-circular gear through the clamping block, and passes through the mounting hole in the helical non-circular gear through the top column. Then, the helical non-circular gear is clamped at both ends along the thickness through the clamping assembly, thereby reducing the rotation of the helical non-circular gear relative to the turntable. When the gear inserting assembly performs the gear inserting operation on the helical non-circular gear, the rotation of the helical non-circular gear relative to the turntable is reduced, thereby improving the manufacturing accuracy of the helical non-circular gear.

[0010] Optionally, the positioning assembly also includes a positioning ring, a plurality of sliding blocks and a positioning spring, the turntable is provided with an annular groove, the annular groove extends along the thickness direction of the turntable, the positioning ring is slidably connected in the annular groove along the thickness direction of the turntable, the positioning spring is used to keep the positioning ring away from the bottom of the annular groove, a plurality of the sliding blocks correspond to a plurality of the top columns one by one, the top columns are arranged on the sliding block, the sliding block is slidably connected to the turntable in the radial direction of the turntable, the axial direction from the top column to the turntable gradually increases along the direction from the sliding block to the top column, and the sliding block is provided with a guiding inclined surface for facilitating the positioning ring to drive the sliding block to move away from the axis of the turntable.

[0011] By adopting the above technical scheme, in order for the mounting hole of the helical non-circular gear to smoothly pass through the top column, there is a gap between the mounting hole and the top column, which can easily cause the helical non-circular gear to be eccentric during the production process; when the staff places the helical non-circular gear on the turntable, the helical non-circular gear is pressed on the top of the positioning ring. When the clamping assembly presses the helical non-circular gear against the turntable, the helical non-circular gear enables the positioning ring to overcome the elastic force of the positioning spring, and the positioning ring moves toward the bottom of the ring groove. The positioning ring abuts against the guiding inclined surface of the sliding block, so that the sliding block moves in the direction away from the axis of the turntable, and the sliding block drives the positioning column to move, and the positioning column abuts against the hole wall of the mounting hole of the helical non-circular gear. At this time, the helical non-circular gear remains coaxial with the turntable, which improves the processing accuracy of the gear inserting assembly when processing the helical non-circular gear.

[0015] By adopting the above technical solution, the gear-slotting assembly is used to perform gear-slotting operations on helical non-circular gears. Through the driving member, the gear-slotting sleeve is rotated along the direction of the guide groove on the guide column. Since the guide groove is arranged obliquely and the oblique gears are also arranged on the outer wall of the gear-slotting sleeve, it conforms to the helical gear process of helical non-circular gears.

[0018] Optionally, a sliding seat is provided on the frame, the turntable and the clamping assembly are both located on the sliding seat, and a moving part for driving the sliding seat to approach the gear inserting assembly is provided on the frame.

[0019] By adopting the above technical solution, the gear shaping cannot be completed in one go, otherwise it will cause excessive wear of the helical gear on the gear shaping sleeve.
