Description

Technical Field

[0001] This utility model relates to the field of worm gear processing technology, specifically to a high-efficiency worm gear tooth surface adjustment mechanism. Background Technology

[0002] A worm gear is a special type of gear whose pitch surface can be a cylindrical surface, a conical surface, or a toroidal surface, and has one or more helical teeth; It meshes with a worm gear to form an interlaced gear pair, typically with an interlacing angle of 90°. The worm's shape resembles a screw, and based on its tooth profile, it can be classified into four types: Archimedean worm, involute worm, normal straight-profile worm, and conical-enclosed cylindrical worm. Worm gear drives have advantages such as compact structure, large transmission ratio, strong load-bearing capacity, and smooth transmission, and are widely used in modern industry. However, errors exist in the tooth surface machining process of worm gears. These machining errors can lead to excessive or insufficient backlash in the worm gear, which has a significant impact on transmission accuracy. Traditional worm gear machining structures are complex and cumbersome to adjust the machined tooth surface, making efficient tooth surface adjustment impossible and limiting their application. This reduces the overall machining effect. Therefore, this utility model proposes an efficient worm gear tooth surface adjustment mechanism. Utility Model Content

[0003] The purpose of this invention is to provide a high-efficiency worm gear tooth surface adjustment mechanism to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency worm gear tooth surface adjustment mechanism, comprising a back plate, wherein primary bearing seats are fixedly installed on the outer walls of both ends of the front side of the back plate, a threaded screw is rotatably connected between the two primary bearing seats, a threaded female seat is sleeved on the threaded screw, the threaded female seat and the threaded screw are threadedly connected, the top end of the threaded screw is fixedly connected to the output shaft of a servo motor, the servo motor is fixedly installed on the outer wall of the primary bearing seat at the top end by bolts, a fixing plate is installed on the outer surface of the threaded female seat, a fine-tuning plate is detachably installed on the fixing plate by bolts, shaft clamps are fixedly installed on the outer walls of both sides of the front side of the fine-tuning plate, and a worm gear body is connected between the two shaft clamps.

[0005] Preferably, a back plate groove is formed on the front outer wall of the back plate between the two primary bearing seats, and a linear guide rail is fixedly installed in the back plate groove.

[0006] Preferably, a guide slide is fixedly installed on the back of the threaded female seat, and the guide slide is in a limiting sliding connection with the linear guide rail.

[0007] Preferably, an assembly plate is fixedly installed on the outer wall of the back panel.

[0008] Preferably, the outer surfaces of both sides of the assembly plate are provided with a plurality of evenly distributed assembly holes, and bolts adapted to the hole diameter are provided in the assembly holes.

[0009] Preferably, the linear guide rail adopts a "convex" structure design, and the shape of the guide slide is adapted to the shape of the linear guide rail.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes servo-driven fine-tuning of the worm gear body to achieve adjustable machining performance. When the worm gear body moves slightly downwards, the tooth surface depth is increased; conversely, when it moves upwards, the tooth surface depth is decreased. This fine-tuning via servo rotation allows for adjustment of the tooth surface depth during worm gear machining, providing excellent tooth surface adjustment characteristics. Furthermore, the tooth surface depth adjustment can be effectively controlled by adjusting the rotation direction and number of rotations of the servo motor, thus improving structural convenience, reducing structural complexity, and minimizing operational steps. This highly efficient tooth surface adjustment significantly reduces limitations and enhances the worm gear tooth surface machining effect. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] Please see Figure 1-4 This utility model provides an embodiment of a high-efficiency worm gear tooth surface adjustment mechanism, including a back plate 1. Primary bearing seats 2 are fixedly installed on the outer walls of both ends of the front side of the back plate 1. A threaded screw 3 is rotatably connected between the two primary bearing seats 2. A threaded female seat 4 is sleeved on the threaded screw 3, and the threaded female seat 4 is threadedly connected to the threaded screw 3. The output shaft of a servo motor 8 is fixedly connected to the top end of the threaded screw 3. The servo motor 8 is fixedly installed on the outer wall of the primary bearing seat 2 at the top end by bolts. With this structural design, the servo motor 8 can drive the threaded screw 3 to rotate clockwise or counterclockwise through its output shaft. When the threaded screw 3 rotates clockwise or counterclockwise, the threaded female seat 4 threadedly connected to it can move up and down along the threaded screw 3.

[0017] In this embodiment, in order to fix the worm gear, a fixing plate is installed on the outer surface of the threaded female seat 4. A fine adjustment plate 9 is detachably installed on the fixing plate by bolts. Shaft clamps 10 are fixedly installed on both sides of the front outer wall of the fine adjustment plate 9. The worm gear body 11 is clamped between the two shaft clamps 10. The shaft clamps 10 are mature existing technology products. As long as they can complete the clamping and fixing of the shaft, they can be applied to this utility model. This specification will not describe them in detail. In practical use, a cutting tool for machining the tooth surface can be installed below the worm body 11, so that the tooth surface of the worm body 11 can be cut by an external machining tool. The servo motor 8 of this utility model can drive the threaded screw 3 to rotate clockwise or counterclockwise through its output shaft. When the threaded screw 3 rotates clockwise or counterclockwise, the threaded female seat 4 connected to it can move up and down along the threaded screw 3. In this way, the up and down movement of the threaded female seat 4 can drive the worm gear body 11 on the fine adjustment plate 9 to move up and down. This invention utilizes servo-driven fine-tuning of the worm gear body 11 during machining. This allows for adjustment during processing. When the worm gear body 11 moves slightly downwards, the tooth surface depth is increased; conversely, when it moves upwards, the tooth surface depth is decreased. This fine-tuning via servo rotation allows for adjustment of the tooth surface depth during worm gear machining, exhibiting excellent tooth surface adjustment characteristics. Furthermore, the tooth surface depth adjustment can be effectively controlled by adjusting the rotation direction and number of rotations of the servo motor 8. This significantly improves the ease of adjustment, reduces structural complexity, and minimizes operational steps, resulting in highly efficient tooth surface adjustment and effectively reducing limitations while improving the worm gear tooth surface machining effect.

[0018] In this embodiment, in order to improve the movement guidance of the threaded female seat 4 and maintain its linear displacement effect, a back plate groove 5 is provided on the front outer wall of the back plate 1 and located between the two primary bearing seats 2. A linear guide rail 6 is fixedly installed in the back plate groove 5. Furthermore, a guide slide 7 is fixedly installed on the back of the threaded female seat 4. The guide slide 7 and the linear guide rail 6 are connected in a limiting sliding connection. The linear guide rail 6 adopts a "convex" structure design, and the shape of the guide slide 7 is adapted to the shape of the linear guide rail 6.

[0019] By using the guide slide 7 and the linear guide rail 6 in combination, a certain displacement guidance can be provided for the up and down movement of the threaded female seat 4, so that it maintains the linear displacement effect and improves the accuracy of displacement.

[0020] In this embodiment, in order to facilitate the installation of the adjustment structure of this utility model, a general assembly plate 12 is fixedly installed on the outer wall of the back of the rear plate 1. Several evenly distributed general assembly holes are opened on the outer surfaces of both sides of the general assembly plate 12, and bolts adapted to the hole diameter are provided in the general assembly holes.

[0021] Working principle: When the worm gear tooth surface adjustment structure of this utility model is in use, it can be installed in a suitable machine tool through the set assembly plate 12, thereby ensuring the normal use of this utility model; In actual use, a cutting tool for machining the tooth surface can be set below the worm body 11, so that the tooth surface of the worm body 11 can be cut by an external machining tool. The servo motor 8 of this utility model can drive the threaded screw 3 to rotate clockwise or counterclockwise through its output shaft. When the threaded screw 3 rotates clockwise or counterclockwise, the threaded female seat 4 connected to it can move up and down along the threaded screw 3. In this way, the up and down movement of the threaded female seat 4 can drive the worm gear body 11 on the fine adjustment plate 9 to move up and down. This invention utilizes servo-driven fine-tuning of the worm gear body 11 during machining. This allows for adjustment during processing. When the worm gear body 11 moves slightly downwards, the tooth surface depth is increased; conversely, when it moves upwards, the tooth surface depth is decreased. This fine-tuning via servo rotation allows for adjustment of the tooth surface depth during worm gear machining, exhibiting excellent tooth surface adjustment characteristics. Furthermore, the tooth surface depth adjustment can be effectively controlled by adjusting the rotation direction and number of rotations of the servo motor 8. This significantly improves the ease of adjustment, reduces structural complexity, and minimizes operational steps, resulting in highly efficient tooth surface adjustment and effectively reducing limitations while improving the worm gear tooth surface machining effect.

[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
