[0041] The expansion sleeve 4 is arranged at the left end of the positioning shaft 3. The setting of the expansion sleeve 4 can quickly position gears 7 of different specifications and facilitate the replacement of the position of the gear 7. Especially for gears 7 with splines, the size of the expansion sleeve 4 is set larger than the size of the spline groove. During the operation of the expansion sleeve 4, there is no need to adjust the angle of the gear 7 and the gear 7 can be directly fixed.

[0042] The processing seat 5 is arranged at the upper end of the machine tool 1, and the processing seat 5 is arranged at the right end of the first groove 11.

[0046] The second groove 31 is set to be semicircular, and the diameter of the second groove 31 is smaller than one-third of the diameter of the positioning shaft 3. The second groove 31 is set to be semicircular so that the first tool 51 can enter the spare part between the positioning shaft 3 and the gear 7 to process part of the spline. The diameter of the second groove 31 is set to be smaller than one-third of the diameter of the positioning shaft 3 to prevent the positioning shaft 3 and the gear 7 from loosening when the gap is too large.

[0048] Embodiment 2: Figure 1-4 As shown, based on the first embodiment, the present embodiment further improves the clamping assembly 6, and the clamping assembly 6 further includes:

[0049] The guide rail 61 is arranged in the first groove 11. The guide rail 61 is arranged in a closed shape. The upper end of the guide rail 61 is arranged in a semicircle. The upper end of the guide rail 61 is arranged concentrically with the first groove 11. The closed shape allows the guide rail 61 to circulate to meet the rotation of the gear 7 at different angles.

[0050] The clamping members 62 are provided in plurality and are evenly arranged in the guide rail 61. The even distribution of the clamping members 62 can ensure that the workpiece is subjected to an equal clamping force during the processing, thereby preventing the workpiece from displacement or instability. The plurality of clamping members 62 can be provided according to the size, shape and processing requirements of the workpiece. An appropriate amount of clamping members 62 can be selected for use, and necessary clamping force adjustments can be made to meet the processing requirements of different workpieces.

[0051] The clamping assembly 6 can be set to perform preliminary fixation when the gear 7 is placed in the first groove 11. After a part of the spline and the tooth profile of the gear 7 are processed, the gear 7 will not be displaced too much and will not fall off after the expansion sleeve 4 is reset inward. The guide rail 61 moves left or right, and the clamping member 62 clamps the gear 7 to rotate the gear 7 to the left or right to the position that needs to be processed. Then the expansion sleeve 4 is expanded to complete the rotation of the gear 7. There is no need to manually rotate the gear 7, and the tooth profile and spline of the gear 7 can be better processed as an integrated whole.

[0052] Embodiment 3: Figure 5As shown, on the basis of Example 2, this embodiment further improves the guide rail 61, and the meshing part of the upper end of the guide rail 61 and the gear 7 is set to be inclined inward. When the clamping member 62 passes through the upper end of the guide rail 61, the clamping member 62 will gradually tilt inward to fix the gear 7, which meets the clamping of gears 7 of different thicknesses. Through the design of the inward-inclined guide rail 61, the clamping member 62 can form a tighter clamping force when fixing the gear 7. This stable and uniform clamping force can prevent the loosening or displacement of the gear 7 during the processing, ensuring the stability and safety of the processing. When the clamping member 62 passes through the guide rail 61, it can automatically adjust and fix the gear 7 without additional adjustment or fixing steps. This convenient operation simplifies the workflow and improves the operating efficiency.

[0053] Embodiment 4: Figure 1-5 As shown, based on embodiments 1-3, this embodiment further provides a method for using a gear processing device, including:

[0054] The gear 7 is placed in the first groove 11 , and the gear 7 is preliminarily clamped by the clamping member 62 to ensure the position and stability of the gear 7 .

[0055] Move the positioning shaft 3 to the right, so that it enters the interior of the gear 7 and axially fixes the gear 7. This ensures that the position of the gear 7 is accurate and will not move.

[0056] The expansion sleeve 4 is used to expand radially outward to fix the gear 7. In this way, the gear 7 can remain stable during the processing without movement or shaking.

[0057] The first cutter 51 is displaced to the left to start machining the spline of the gear 7. The spline portion of the gear 7 can be accurately formed by appropriate cutting and machining methods.

[0058] The second cutter 52 moves downward and reciprocates through the guide groove 53. In this way, the second cutter 52 can complete the processing of the tooth profile of the gear 7. The existence of the guide groove 53 can ensure the accuracy and repeatability of the processing.

[0059] After completing the partial processing of the gear 7 tooth profile and spline, the first tool 51, the second tool 52 and the expansion sleeve 4 are reset in sequence. The reset operation of these components can accurately return to the initial position to prepare for the next processing step.

[0060] The guide rail 61 moves to the right, so that the clamping member 62 clamps the gear 7 and rotates it to the position of the unprocessed part of the gear 7. Like this, the following processing can continue, and the complete processing of the gear 7 is ensured.

[0061] Repeat the above steps, and perform the movement and processing operations of the expansion sleeve 4, the first tool 51 and the second tool 52 in sequence until the entire processing of the gear 7 is completed. Each round of movement will process a small area, and through continuous repetition, the processing process of the entire gear 7 is finally completed.

[0062] Although the above describes the illustrative specific implementation methods of the present application so that technicians in this technical field can understand the present application, the present application is not limited to the scope of the specific implementation methods. For ordinary technicians in this technical field, as long as various changes are within the spirit and scope of the present application defined and determined by the attached claims, all application creations using the concept of the present application are protected.
