[0002] As precision transmission components, the quality of the gear teeth in motors directly affects the performance and lifespan of the entire motor. In subsequent machining processes such as drilling, chamfering, and deburring, it is often necessary to adjust the gear angle circumferentially to expose the teeth to be machined.

[0003] Currently, traditional machining methods generally use three-jaw chucks with manual alignment, or simple mandrels with pressure plates for fixation, which have obvious drawbacks: First, universal chucks can easily damage the tooth surface when clamping the outer circle of gears, and different specifications of gears require different chuck jaws, resulting in poor adaptability; Second, the adjustment of the circumferential angle of the gear relies on manual loosening of bolts and manual rotation, making realignment difficult, resulting in low positioning accuracy and efficiency, and repeated clamping can easily introduce errors; Third, the metal chips generated during machining can easily accumulate on the working surface of the fixture, affecting positioning accuracy and even scratching the finished surface.

[0004] Therefore, this application provides a motor gear machining fixture to solve the above-mentioned technical problems. Utility Model Content

[0031] like Figure 1-4 As shown, an embodiment of this utility model provides a motor gear machining fixture, including a base 2. The base serves as the supporting body of the entire fixture and is made of a high-strength metal material, such as alloy structural steel. This material has high strength and toughness, ensuring that the base 2 has sufficient stability and rigidity during machining and is not easily deformed. The upper end face of the base 2 has a circular opening 202.

[0032] A rotatable worm gear disk 4 is rotatably mounted inside the base 2. The worm gear disk 4 is connected to the base via a precision bearing. This bearing is a high-precision angular contact ball bearing, capable of withstanding large axial and radial loads, ensuring that the worm gear disk 4 rotates flexibly and smoothly. The worm gear disk 4 is located at the bottom of the movable opening 202, and a positioning cylinder 5 for fixing the shaft hole of the motor gear 1 to be processed is fixed in the middle of its upper end face. Specifically, the positioning cylinder 5 extends out of the upper end face of the base 2 from the center of the movable opening 202. Two mirror-movable support plates 6 are symmetrically arranged on both sides of the positioning cylinder 5. The support plates 6 are made of the same material as the positioning cylinder 5, and their bottoms slide against the upper surface of the worm gear disk 4 to ensure stability during movement. The outer surface of the support plates 6 is provided with anti-slip texture to increase the friction between the support plates and the inner wall of the motor gear shaft hole, improving the stability of the fixation.

[0033] A vertical stud 501 is rotatably mounted at the central shaft inside the positioning cylinder 5. The top of the stud 501 extends beyond the top of the positioning cylinder 5, facilitating rotation by the operator using tools. A sliding block 502 is provided inside the positioning cylinder 5, with a threaded hole in the center for the stud 501 to pass through. The inner surface of the threaded hole is hardened to improve its wear resistance and ensure the fit accuracy between the stud and the threaded hole during long-term use. When the stud 501 is rotated, the sliding block 502 moves up and down along the stud under the action of the thread. Symmetrical strip-shaped through slots are provided on both sides of the positioning cylinder 5. A connecting rod 503 extends from the through slot and connects to the support plate 6. As the sliding block 502 moves up and down, the connecting rod 503 drives the support plate 6 to perform a mirror translation in the horizontal direction, thereby supporting and fixing motor gears of different diameters.

[0034] A fixing seat 8 is fixed to the upper edge of the base 2. The fixing seat 8 is tightly connected to the base with bolts made of high-strength stainless steel to ensure a secure installation. A positioning block 11 is provided on the side of the fixing seat 8 facing the positioning cylinder 5, for engaging in the gear groove. The positioning block 11 is made of hard alloy, such as tungsten carbide alloy, which has high hardness and wear resistance, allowing it to accurately engage in the gear groove of the motor gear, achieving precise positioning of the motor gear. Specifically, a horizontal screw 9 is threaded through the fixing seat 8. A positioning tooth 10 is fixed to the end of the screw 9 facing the positioning cylinder 5. The positioning tooth 10 is made of the same material as the positioning block 11. One end of the positioning block 11 is vertically embedded in the side of the positioning tooth 10. By rotating the screw 9, the position of the positioning block 11 can be adjusted, allowing it to move horizontally and engage in the gear groove, enhancing positioning stability. A handle is provided at the other end of the screw 9. The surface of the handle is covered with a rubber sleeve to increase the comfort of the operator when rotating the screw.

[0035] A slag collection groove 201 is provided on the upper edge of the base 2 away from the fixed base 8, which can fully receive the waste chips generated during processing. A slag collection bucket 3 is slidably inserted into the bottom of the slag collection groove 201. The slag collection bucket 3 is located directly below the edge of the motor gear 1 to be processed, which is fixed on the positioning cylinder 5, ensuring that the waste chips can fall accurately into the slag collection bucket. A handle is provided on the outside of the slag collection bucket 3 for easy removal and insertion by the operator.

[0036] A worm gear 7 is rotatably mounted inside the base 2. The worm gear 7 meshes with the edge of the worm wheel 4 to form a transmission connection. The worm gear 7 is a high-precision worm, and its tooth profile is precisely machined to ensure smooth and noiseless transmission with the worm wheel. One end of the worm gear 7 extends beyond the side of the base 2 and is fixed with a screw cap. The screw cap is made of plastic and has anti-slip textures on its surface. The operator can rotate the screw cap to drive the worm gear 7 to rotate, which in turn drives the worm wheel 4 to rotate. The rotation of the worm wheel 4 will drive the positioning cylinder 5 and the motor gear 1 to be processed, which is fixed on the positioning cylinder 5, to rotate together, thereby realizing the processing of different positions of the motor gear.

[0037] The working principle provided by this utility model is as follows: In actual use, the operator first places the shaft hole of the motor gear 1 to be processed onto the positioning cylinder 5, then rotates the stud 501 to move the slider 502 downward, and the connecting rod 503 drives the support plate 6 to move outward until the support plate 6 tightly abuts against the inner wall of the shaft hole of the motor gear 1 to be processed, thereby achieving the initial fixation of the motor gear.

[0038] Next, the screw 9 is rotated, causing the positioning block 11 to engage in the tooth groove of the motor gear 1 to be processed, further enhancing the stability of the positioning. During the processing, when other positions of the motor gear 1 need to be processed, the operator only needs to rotate the screw cap, which drives the worm gear 4 to rotate through the worm 7, thereby rotating the motor gear 1 to the required position and fixing it in place by engaging the positioning block 11. This eliminates the need to disassemble and reinstall the gear, making the operation convenient and quick, and greatly improving processing efficiency.

[0039] Meanwhile, the waste generated during the processing will fall into the slag collection hopper 3. When the waste accumulates to a certain extent in the slag collection hopper 3, the operator only needs to pull out the slag collection hopper 3, clean the waste, and reinsert it, thus maintaining a clean working environment.

[0040] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
