Description

Technical Field

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

[0002] 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. Summary of the invention

[0003] The purpose of the present invention is to overcome the above technical deficiencies and provide a clamping device for a horizontal gear shaping machine to solve the technical problem of uneven inner walls of parts to be processed in the prior art.

[0004] In order to achieve the above technical objectives, the technical solution of the present invention provides a clamping device for a horizontal gear shaping machine, which is characterized by comprising:

[0005] Support seat;

[0006] A guide rail mechanism, comprising at least one first guide rail and a first slide, wherein the first guide rail is arranged on the support seat, and the first slide can be slidably connected to the first guide rail;

[0007] The rotating mechanism comprises a motor and a clamping assembly, wherein the motor is arranged on the first slide, and the clamping assembly is connected to the output shaft of the motor and is used to clamp the part to be processed;

[0008] A linear drive mechanism is disposed on the support seat, and an output shaft of the linear drive mechanism is connected to the first slide table, so as to drive the first slide table to move along the guide of the first guide rail.

[0009] Compared with the prior art, the beneficial effects of the present invention include: the part to be processed is coaxially connected to the output shaft of the motor, and then the motor is started. Under the action of the current, the motor drives the part to be processed to rotate, and the first slide is driven to move along the guide of the first guide rail by the linear drive mechanism. The first slide drives the motor and the part to be processed to move along the guide of the first guide rail, and the rotating gear cutter is slowly approached to the part to be processed, and the inner wall of the part to be processed is slowly processed. When the gear cutter rotates, each tooth of the gear cutter cuts the part to be processed little by little. The part to be processed is driven to rotate by the motor, so that the gear cutter performs linear processing on the inner wall of the part to be processed instead of the original point processing. The inner wall of the processed part is smoother and has higher precision. The linear drive mechanism can be used to control the radial feed amount of the motor and the part to be processed along the gear cutter, thereby realizing the radial feed of the gear cutter. When the gear cutter needs to be retracted after the axial processing is completed, the linear drive mechanism can be used to control the motor and the part to be processed to move relative to the gear cutter, thereby realizing the retraction of the gear cutter.
