Description

Technical Field

[0001] This utility model relates to the field of gearbox technology, specifically a grinding device for gearbox production and processing. Background Technology

[0002] As a key transmission component in mechanical equipment, the quality and performance of the gearbox are crucial to the operation of the entire mechanical system. A gearbox typically consists of multiple gears, bearings, and a housing, transmitting torque and speed through gear meshing. During the manufacturing process, the surface quality of the gearbox directly affects its service life and transmission efficiency.

[0003] In the production and processing of gearboxes, the grinding process is crucial, as it directly affects the smoothness of the gearbox surface and the overall quality. To improve the grinding effect, existing grinding devices usually have a spring assembly at the connection of the grinding head. The main purpose of this design is to absorb the impact force generated by friction and contact during the grinding process, while also playing a buffering role, making the contact between the grinding head and the gearbox surface more gentle and uniform, thereby significantly improving the grinding quality and efficiency.

[0004] However, in practical applications, the surface hardness of gearboxes from different batches or models often varies. This variation in hardness places higher demands on the adaptability of the grinding process. When the surface hardness of the gearbox is high, if the preload of the spring is too small, the grinding head may not be able to effectively contact the surface, thus affecting the grinding effect. Conversely, if the surface hardness of the gearbox is low and the preload of the spring is too large, the surface of the gearbox may be damaged due to excessive pressure, which is also not conducive to ensuring the grinding quality.

[0005] In view of the above, this application is hereby submitted. Utility Model Content

[0006] The purpose of this invention is to provide a grinding device for gearbox production and processing, so as to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides a grinding device for gearbox production and processing, including a connecting column, a connecting box fixedly installed at the end of the connecting column, a second gear rotatably installed on the end face of the connecting box, a screw rotatably installed on the inner wall of the second gear, a threaded disc threaded on the outer wall of the screw, which can easily adjust the moving position of the threaded disc, a spring rotatably installed at the end of the threaded disc, a support column rotatably installed at the end of the spring away from the threaded disc, and a grinding head fixedly installed at the end of the support column.

[0008] Furthermore, a fixed plate is slidably mounted on the outer wall of the support column, allowing the support column to move on the fixed plate. A support plate is fixedly mounted on the outer wall of the fixed plate, and the end of the support plate away from the fixed plate is fixedly connected to the surface of the second gear. When it is necessary to adjust the pressure applied by the grinding head, it can be achieved directly by adjusting the elastic force of the spring connected to the support column.

[0009] Furthermore, a bevel gear two is fixedly installed at one end of the screw near the gear two, and the outer wall of the bevel gear two is meshed with the bevel gear one. During normal operation, the bevel gear one and the bevel gear two are in a non-contact state, and the side wall of the bevel gear one is fixedly installed on the drive end of the telescopic motor.

[0010] Furthermore, a fixing plate is fixedly installed on the side wall of the connecting box, a rotary motor is embedded in the inner wall of the fixing plate, a gear one is fixedly installed on the drive end of the rotary motor, and the side wall of gear one is meshed with gear two, so that the rotary motor can directly drive the rotation of gear two through gear one.

[0011] Furthermore, the inner wall of the support plate is provided with a limiting groove, and a support rod is slidably installed on the inner wall of the limiting groove. Due to the sliding constraint of the support rod in the limiting groove, the threaded disc is firmly restricted and can only move along the axial direction of the screw. The end of the support rod is fixedly connected to the outer wall of the threaded disc.

[0012] Furthermore, the side wall of the connecting box is provided with an observation window, and a transparent acrylic plate is installed on the surface of the observation window.

[0013] Furthermore, the number of support plates is four, and the multiple support plates are evenly distributed in a circle on the outer wall of the fixed plate.

[0014] Furthermore, the grinding head is made of tungsten steel, and the surface of the grinding head is provided with grinding texture.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by driving the first bevel gear and the second bevel gear to mesh through the telescopic motor, the screw is rotated and the threaded disc moves on the screw, thereby adjusting the elastic force of the spring and realizing the precise adjustment of the pressure of the grinding head, ensuring that it can effectively fit the surface during the grinding process without damaging the gearbox due to excessive pressure.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a grinding device for gearbox production and processing, including a connecting column 1, a connecting box 2 fixedly installed at the end of the connecting column 1, a gear 8 rotatably installed on the end face of the connecting box 2, and a screw 17 rotatably installed on the inner wall of the gear 8. A threaded disc 10 is threadedly installed on the outer wall of the screw 17, so that the moving position of the threaded disc 10 can be easily adjusted through the threaded engagement of the screw 17 and the threaded disc 10. A spring 11 is rotatably installed at the end of the threaded disc 10, and a support column 13 is rotatably installed at the end of the spring 11 away from the threaded disc 10. A grinding head 14 is fixedly installed at the end of the support column 13. When the position of the threaded disc 10 is adjusted, the elastic force of the spring 11 is also adjusted. This adjustment mechanism ensures that the grinding head 14 can apply uniform pressure when contacting the surface of the gearbox, thereby effectively avoiding local excessive wear or incomplete grinding.

[0023] Please see Figure 1This utility model provides a technical solution: a grinding device for gearbox production and processing, including a fixed plate 12 slidably mounted on the outer wall of a support column 13, so that the support column 13 can move flexibly on the fixed plate 12 and remain stable. A support plate 9 is fixedly mounted on the outer wall of the fixed plate 12, and the end of the support plate 9 away from the fixed plate 12 is tightly fixedly connected to the surface of the gear 8. This combination provides a stable and flexible support structure for the support column 13. Since the support column 13 is slidably mounted on the fixed plate 12, when it is necessary to adjust the pressure applied by the grinding head 14, it can be directly achieved by adjusting the elastic force of the spring 11 connected to the support column 13.

[0024] Please see Figure 2 This utility model provides a technical solution: a grinding device for gearbox production and processing, including a screw 17 with a bevel gear 15 fixedly installed at one end near the gear 8, and the outer wall of the bevel gear 15 meshing with the bevel gear 7. The side wall of the bevel gear 7 is fixedly installed on the drive end of the telescopic motor 6. Normally, the bevel gear 7 and the bevel gear 15 are in a non-contact state, which means that when the spring force of the spring 11 does not need to be adjusted, the telescopic motor 6 remains silent and does not consume additional energy. When it is necessary to adjust the spring force of the spring 11 to change the pressure of the grinding head 14, the telescopic motor 6 is activated. Driven by the telescopic motor 6, the bevel gear 7 will perform telescopic movement until it meshes with the bevel gear 15. The rotation of the telescopic motor 6 will drive the bevel gear 7 to rotate, and then drive the bevel gear 15 and the screw 17 to rotate through the meshing relationship. At this time, the rotation of the screw 17 will cause the threaded disc 10 to move on the screw 17, and then through the transmission of the spring 11 and the support column 13, the pressure of the grinding head 14 can be precisely adjusted.

[0025] Please see Figure 1 , Figure 2 This utility model provides a technical solution: a grinding device for gearbox production and processing, including a fixing plate 3 fixedly installed on the side wall of the connecting box 2, a rotary motor 4 embedded in the inner wall of the fixing plate 3, a gear 5 fixedly installed on the drive end of the rotary motor 4, and a meshing connection between the side wall of the gear 5 and the gear 8, realizing that the rotary motor 4 directly drives the rotation of the gear 8 through the gear 5. This direct power transmission method reduces energy loss in the conversion process and ensures efficient and stable power output.

[0026] Please see Figure 3 , Figure 4This utility model provides a technical solution: a grinding device for gearbox production and processing, including a limiting groove 18 formed on the inner wall of a support plate 9, a support rod 16 slidably installed on the inner wall of the limiting groove 18, and the end of the support rod 16 fixedly connected to the outer wall of the threaded disc 10. Therefore, it can effectively restrict the rotation of the threaded disc 10. When the screw 17 rotates, due to the sliding constraint of the support rod 16 in the limiting groove 18, the threaded disc 10 is firmly restricted and can only move in translational motion along the axial direction of the screw 17, but cannot rotate.

[0027] Please see Figure 1 , Figure 2 This utility model provides a technical solution: a grinding device for gearbox production and processing, including a viewing window provided on the side wall of the connecting box 2, a transparent acrylic plate installed on the surface of the viewing window, and four support plates 9, which are evenly distributed in a circle on the outer wall of the fixed plate 12.

[0028] Please see Figure 1 , Figure 4 This utility model provides a technical solution: a grinding device for gearbox production and processing, including a grinding head 14 made of tungsten steel, with grinding patterns on the surface of the grinding head 14.

[0029] Working principle: When the pressure of the grinding head 14 needs to be adjusted, the telescopic motor 6 is activated. A bevel gear 7 is fixedly mounted on the drive end of the telescopic motor 6. The bevel gear 7 extends and retracts, meshing with a second bevel gear 15. The second bevel gear 15 is fixedly mounted on the end of the screw 17 near the second gear 8. The rotation of the telescopic motor 6 drives the bevel gears 7 and 15 to rotate, which in turn drives the screw 17 to rotate. The threaded disc 10 moves on the screw 17, thereby adjusting the elasticity of the spring 11. This ensures that the grinding head 14 applies uniform pressure when grinding the surface of the gearbox, effectively avoiding localized excessive wear or incomplete grinding.
