Description

Technical Field

[0001] The utility model relates to the technical field of horizontal gear shaping machines, in particular to a clamping device used for horizontal gear shaping machines. Background Art

[0002] The gear shaping cutter is used as a tool to process the tooth shape of gears, racks, etc. This processing method is called "gear shaping". When shaping gears, the gear shaping cutter performs reciprocating cutting motion up and down, and rolls relative to the workpiece at the same time. Gear shaping machines are mainly used to process multi-link gears and internal gears. With accessories, they can also process racks. Using special tools on gear shaping machines can also process non-circular gears, incomplete gears, and internal and external formed surfaces.

[0003] When the internal gear is processed by a gear shaping machine, the part to be processed is fixed by a clamp, and the helical gear is processed on the inner wall of the part to be processed by rotating the gear shaping cutter. Each tooth of the gear shaping cutter continuously contacts the inner wall of the part to be processed as it rotates, and the inner wall of the part to be processed is processed little by little. This method has defects. When the inner wall of the part to be processed is processed by the gear shaping cutter, this method has defects. Since the rack is continuously buckled out by the teeth of the gear shaping cutter, the inner wall of the part to be processed becomes uneven, and the accuracy of the internal gear is insufficient.

[0004] In the patent document with the publication number CN213857459U, a clamping device for a horizontal gear shaping machine is proposed, which includes a support seat, a guide rail mechanism, a rotating mechanism, and a linear drive mechanism. The guide rail mechanism includes at least one first guide rail and a first slide. The first guide rail is arranged on the support seat, and the first slide can be slidably connected to the first guide rail; the rotating mechanism includes a motor and a clamping assembly. The motor is arranged on the first slide, and the clamping assembly is connected to the output shaft of the motor for clamping the part to be processed; the linear drive mechanism is arranged on the support seat, and the output shaft of the linear drive mechanism is connected to the first slide, which is used to drive the first slide to move along the guide of the first guide rail. The inner wall of the part processed by the utility model is relatively smooth.
