Description

Technical Field

[0001] This invention relates to the field of roller machining technology, specifically to a grinding disc device and method for finishing the rolling surface of cylindrical rollers. Background Technology

[0002] Grinding disc equipment for precision machining of cylindrical rollers is a type of mechanical equipment specifically designed for high-precision surface processing of cylindrical rollers. Its main function is to remove irregularities and roughness from the workpiece surface through the relative movement between the grinding disc and the workpiece surface, thereby achieving precise dimensional requirements and surface quality. Cylindrical rollers are widely used in rolling bearings, where extremely high precision is required. Therefore, the grinding process not only removes surface burrs but also ensures that their geometry, surface roughness, and hardness meet standards.

[0003] Existing traditional cylindrical roller finishing grinding disc equipment mostly only grinds the two end faces of the rollers. However, the fine machining of the rolling contact surface of the rollers usually requires separate dedicated equipment. Because the rolling contact surface has extremely high precision requirements, existing equipment often cannot effectively handle this part in the same processing step. Therefore, additional equipment is needed for precision machining. However, independent rolling contact surface machining equipment is expensive and has high maintenance costs, making it difficult for many companies to popularize and afford the related expenses in practical applications. In addition, although existing two end face grinding equipment is simple, it cannot meet the high requirements for the overall precision and surface quality of the rollers, resulting in unsatisfactory overall performance of the final product. Due to the issues of equipment price and process complexity, many small and medium-sized enterprises find it difficult to carry out efficient cylindrical roller finishing, which affects the improvement of production efficiency and product quality. To address this, we propose a grinding disc equipment and method for finishing the rolling surface of cylindrical rollers. Summary of the Invention

[0014] The method of using a grinding disc device for finishing the rolling surfaces of cylindrical rollers includes the following steps: S1. When grinding the rolling surface of the hollow roller body is required, first use an Allen wrench in conjunction with the adjustment mechanism. When the adjustment mechanism is running in the forward direction, it will synchronously drive the inner support positioning mechanism to complete the opening and closing motion. When the inner support positioning mechanism is closed, the hollow roller body will be fitted onto the outside of the inner support positioning mechanism. S2. Use the Allen wrench again to control the adjustment mechanism to run in reverse. The adjustment mechanism will synchronously drive the inner support positioning mechanism to complete the opening movement. At this time, the inner support positioning mechanism is stably supported inside the hollow roller body and automatically finds the center inside the hollow roller body. S3. After the hollow roller body is positioned, the lifting mechanism is started. At this time, the lifting mechanism will simultaneously drive the positioning component and the grinding component to rise, and drive the upper surface of the grinding component to fit against the outer wall of the hollow roller body. After the above steps are completed, the stepper motor is started. S4. When the stepper motor starts or synchronously drives the upper synchronization mechanism and the grinding component to rotate, when the lower bevel gear in the synchronization mechanism rotates, it will simultaneously drive several inner support positioning mechanisms and several adjustment mechanisms to rotate. At this time, the hollow roller body will also rotate with the inner support positioning mechanism. The rolling surface of the hollow roller body will be in contact with the upper surface of the grinding disc body for grinding. S5. The diameter of several bevel gears is smaller than that of the lower bevel gear disk, so the rotation speed of several bevel gears will be faster than that of the lower bevel gear disk. Since the upper bevel gear disk is fixed, while the lower bevel gear disk drives several bevel gears, several internal support positioning mechanisms and several adjustment mechanisms to rotate, several bevel gears, several internal support positioning mechanisms and several adjustment mechanisms will also complete the revolution, thereby accelerating the grinding of the outer surface of the hollow roller body.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This grinding disc equipment for precision machining of cylindrical roller rolling surfaces forms a highly efficient grinding system through the close cooperation of its various components. During operation, the adjusting mechanism precisely controls the opening and closing of the inner support positioning mechanism to ensure that the hollow roller body is always in a stable positioning state. The synchronizing mechanism, through an efficient gear transmission system, ensures that the inner support positioning mechanism and the adjusting mechanism complete the synchronous movement of revolution and rotation, thereby improving the contact efficiency between the grinding disc body and the hollow roller body. The lifting mechanism, through precise lifting control, ensures uniform contact between the grinding components and the outer wall of the hollow roller body, ensuring a stable distribution of grinding pressure. The transmission relationship and coordination between each structure not only ensure the stability of the equipment during operation but also improve the grinding efficiency and accuracy. By precisely controlling the movement of the inner support positioning mechanism and the transmission of the synchronizing mechanism, this equipment can achieve efficient precision machining of cylindrical roller rolling surfaces, meeting high-precision machining requirements.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-3As shown, the present invention provides a technical solution: a grinding disc device and method for precision machining of the rolling surface of cylindrical rollers, comprising a support assembly 1 and a plurality of hollow roller bodies 8. The upper end of the support assembly 1 is provided with a plurality of internal support positioning mechanisms 6 arranged in a ring for internally supporting and positioning the hollow roller bodies 8.

[0020] Furthermore, this grinding disc equipment for precision machining of cylindrical roller rolling surfaces forms a highly efficient grinding system through the close cooperation of its various components. During operation, the adjusting mechanism 7 precisely controls the opening and closing of the inner support positioning mechanism 6, ensuring that the hollow roller body 8 is always in a stable positioning state. The synchronizing mechanism 5, through a highly efficient gear transmission system, ensures that the inner support positioning mechanism 6 and the adjusting mechanism 7 complete synchronous movements of revolution and rotation, thereby improving the contact efficiency between the grinding disc body 404 and the hollow roller body 8. The lifting mechanism 2, through precise lifting control, ensures uniform contact between the grinding component 4 and the outer wall of the hollow roller body 8, ensuring a stable distribution of grinding pressure. The transmission relationship and coordination between each structure not only ensure the stability of the equipment during operation but also improve the grinding efficiency and precision. By precisely controlling the movement of the inner support positioning mechanism 6 and the transmission of the synchronizing mechanism 5, this equipment can achieve efficient precision machining of cylindrical roller rolling surfaces, meeting high-precision machining requirements.

[0021] In the preferred embodiment of this technical solution, please refer to Figure 3 , Figure 5 and Figure 6As shown, the support assembly 1 includes a base plate 101, with first longitudinal guide tubes 102 fixedly connected to the four diagonal corners of the upper end of the base plate 101.

A support beam 104 is fixedly connected to the upper end of the support upright plate 103. The positioning assembly 3 includes four guide posts 301, which are longitudinally slidably sleeved inside the four first longitudinal guide tubes 102. A connecting arm 302 is fixedly connected to the upper end of each of the four guide posts 301. A support ring 303 is fixedly connected between the four connecting arms 302. The grinding assembly 4 includes a positioning steel ring 401, which is fixedly sleeved inside the support ring 303 near the center via a bearing. A spline sleeve 402 is fixedly connected to the upper end of the positioning steel ring 401. A steel hub 403 is fixedly sleeved on the outside of the spline sleeve 402. A grinding disc body 404 is fixedly sleeved on the outside of the steel hub 403.

[0022] Furthermore, the support assembly 1 provides basic support for the equipment, ensuring the stable operation of each component. The support assembly 1 includes a base plate 101 and a support upright plate 103. The base plate 101 has four diagonally fixed connections to the upper end of the base plate 101. These guide tubes ensure the stable sliding of the upper positioning assembly 3. The positioning assembly 3 is composed of guide posts 301 and connecting arms 302, etc., to ensure the precise positioning of the grinding assembly 4. The guide posts 301 slide within the first longitudinal guide tubes 102. The support assembly 1 and the positioning assembly 3 together ensure the docking between the grinding assembly 4 and the hollow roller body 8, maintaining the grinding accuracy.

[0023] In the preferred embodiment of this technical solution, please refer to Figure 4As shown, the lifting mechanism 2 includes a base plate 201, which is fixedly connected to the upper center of the base plate 101. Two second longitudinal guide tubes 202 are fixedly connected to the four diagonal points of the upper center of the base plate 201. Guide rails 203 are fixedly connected to both sides of the upper center of the base plate 201. A hydraulic cylinder 204 is fixedly connected to one side of the upper center of the base plate 201. A push block 205 is fixedly connected to the telescopic end of the hydraulic cylinder 204. Guide sleeves 206 are fixedly connected to both sides of the lower center of the push block 205. Two guide sleeves 206 are slidably sleeved on the outside of two guide rails 203. Pulleys 207 are rotatably connected to the two mutually distant sides of the push block 205. A support plate 20 is fixedly connected to the lower center of the four second longitudinal guide tubes 202. 8. A stepper motor 209 is fixedly connected to the upper center of the support plate 208.

Two pulleys 207 are slidably sleeved inside the two inclined slots 2015 respectively.

[0024] Furthermore, the main function of the lifting mechanism 2 is to adjust the lifting of the positioning component 3 and the grinding component 4, so that the grinding disc body 404 can accurately contact the outer wall of the hollow roller body 8, thereby performing effective finishing. The lifting mechanism 2 controls the movement of the push block 205 through the hydraulic cylinder 204. The push block 205 slides on the guide rail 203 through the guide sleeve 206, ensuring that the push block 205 moves accurately and smoothly. When the hydraulic cylinder 204 extends or retracts, the push block 205 drives the positioning component 3 and the grinding component 4 to rise or fall. The pulleys 207 on both sides of the push block 205 make the overall movement more stable, effectively avoiding the problem of inconsistent grinding caused by uneven lifting. Through precise lifting adjustment, the lifting mechanism 2 ensures that the upper surface of the grinding disc body 404 is completely in contact with the outer wall of the hollow roller body 8, providing uniform contact pressure, which is crucial for improving the grinding quality. In addition, the stepper motor 209 also coordinates with the lifting mechanism 2 to ensure the smooth progress of the entire grinding process and avoid poor grinding caused by unstable or unbalanced lifting.

[0025] In the preferred embodiment of this technical solution, please refer to Figure 7As shown, the synchronization mechanism 5 includes a splined shaft 501 and a positioning steel tube 502.

A central shaft column 504 is rotatably sleeved at the center of the lower bevel gear disk 503 via a bearing. A central support disk 505 is fixedly connected to the upper end of the central shaft column 504. Several cylindrical connecting rods 506 are fixedly connected in a ring at equal intervals on the outer side of the central support disk 505. Bevel gears 507 are rotatably sleeved on the outer side of the several cylindrical connecting rods 506 via bearings. Several bevel gears 507... The transmission between the 7 and the lower bevel gear 503 is meshing. The center of the far-away ends of the bevel gears 507 are all fixedly connected to the docking post 508. The center of the far-away side of the docking post 508 is fixedly connected to the guide rod 509. The lower end of the positioning steel tube 502 is fixedly connected to the upper bevel gear 5010.

The outer side of the positioning steel ring 5011 is equidistantly arranged in a ring and fixedly connected to several lugs 5012. The docking post 508 is rotatably sleeved inside the lugs 5012 through a bearing.

[0026] Furthermore, the synchronization mechanism 5 is responsible for transmitting the power provided by the stepper motor 209 to each inner support positioning mechanism 6 and adjustment mechanism 7, achieving precise revolution and rotation. The spline shaft 501 is connected to the stepper motor 209 and transmits power to the lower bevel gear disk 503 through the spline sleeve 402. The lower bevel gear disk 503 is connected to the central shaft column 504 through bearings, driving the central support disk 505 to rotate. Multiple cylindrical connecting rods 506 are fixedly connected to the outer edge of the central support disk 505. These connecting rods are rotatably connected to the bevel gear 507 through bearings. The bevel gear 507 meshes with the lower bevel gear disk 503 for transmission. The lower bevel gear 503 is driven to rotate, which in turn drives the inner support positioning mechanism 6 and the adjustment mechanism 7 to complete their rotation and revolution. Due to its smaller diameter, the bevel gear 507 in the synchronization mechanism 5 rotates at a faster speed, thus accelerating the movement of the inner support positioning mechanism 6 and the adjustment mechanism 7. This increases the frictional contact area between the outer surface of the hollow roller body 8 and the grinding disc body 404, accelerating the grinding process. The upper bevel gear 5010 is fixed, and through gear meshing and transmission between the lower bevel gear 503 and the bevel gear 507, the synchronous rotation and revolution are ensured, thereby improving the overall transmission efficiency and grinding effect.

The four second link 6016 are rotatably connected to the end of the four inner support plates 6010 away from the four inner support plates 6010. The end of the transverse slide bar 6012 away from the toothed bar 6014 is fixedly fitted into the center of the inside of the connecting plate 6017.

[0028] Furthermore, the inner support positioning mechanism 6 is responsible for firmly fixing the hollow roller body 8 inside the grinding equipment, ensuring that the roller maintains precise positioning throughout the grinding process. The hollow drive shaft 601 is connected to the docking column 508 and transmits kinetic energy by rotation, driving the first docking plate 603 and the second docking plate 606 to rotate. Between these two docking plates, the transverse slide bar 6012 and the toothed bar 6014 cooperate with each other to precisely adjust the opening and closing state of the inner support positioning mechanism 6, ensuring that the four inner support plates 6010 are fully supported when needed. The hollow roller body 8 is stably fixed in place. The inner support plate 6010 is designed to contact the hollow roller body 8 through the anti-slip rubber sheet 6011, ensuring that the hollow roller body 8 will not slide or deviate during processing. The transverse slide bar 6012 slides laterally under the guidance of the toothed bar 6014. The return spring 6015 helps the inner support plate 6010 maintain a stable supporting force. This structure can be automatically adjusted according to the size of the hollow roller body 8, ensuring that the roller will not deviate from its center during processing, thus improving the accuracy and efficiency of grinding.

[0029] In the preferred embodiment of this technical solution, please refer to Figure 10 As shown, the adjustment mechanism 7 includes a protective cover 701, which is fixedly sleeved inside the slot 602 at the upper center. Two baffles 702 are fixedly connected to the two sides of the protective cover 701 that are far apart from each other. A rotating shaft 703 is rotatably sleeved at the upper center of the two baffles 702 via two bearings. A worm gear 704 is fixedly sleeved at the outer center of the rotating shaft 703. An internal hexagonal knob 705 is fixedly connected to one end of the rotating shaft 703 near the first mating plate 603. A support shaft 706 is rotatably sleeved at the lower center of the protective cover 701 via two bearings. A worm wheel 707 and a spur gear 708 are fixedly sleeved at the outer center of the support shaft 706 at both ends. The worm gear 704 and worm wheel 707 are in helical meshing transmission, and the spur gear 708 and gear bar 6014 are in meshing transmission.

[0030] Furthermore, the adjustment mechanism 7 controls the opening and closing movement of the inner support positioning mechanism 6 by rotating the hexagonal knob 705. When the hexagonal knob 705 is rotated, the adjustment mechanism 7 can precisely adjust the movement of the inner support positioning mechanism 6 through the transmission between the rotating shaft 703, the worm 704, and the worm wheel 707. The helical meshing transmission of the worm 704 and the worm wheel 707 makes the adjustment smoother and less susceptible to external interference. The adjustment mechanism 7 is also equipped with a protective cover 701 and a baffle 702. These structures can effectively protect the internal transmission components and avoid equipment failure caused by wear or external damage. This mechanism provides a flexible operating method. Users can precisely adjust the opening and closing of the inner support positioning mechanism 6 by simple rotation, further improving the convenience and accuracy of equipment operation. Stepper motor 20 Stepper motor 209 plays a crucial role in synchronization mechanism 5. Through precise stepping control, it ensures the synchronization of the entire transmission system. Stepper motor 209 drives lower bevel gear 503 through spline shaft 501, which in turn drives bevel gear 507 for efficient power transmission. Since the rotational speed of bevel gear 507 is faster than that of lower bevel gear 503, this efficient transmission mechanism can quickly accelerate the rotation of hollow roller body 8 and make its surface quickly come into frictional contact with grinding disc body 404, thereby accelerating the grinding process. Stepper motor 209 also ensures the consistency of rotational speed during the grinding process through precise control, which is crucial for ensuring the consistency of grinding effect. Synchronization mechanism 5 ensures the synchronous movement of each component through precise gear meshing, improving the overall efficiency of the equipment.

[0031] Please see Figure 1-10 The method of using a grinding disc device for finishing the rolling surfaces of cylindrical rollers includes the following steps: S1. When grinding the rolling surface of the hollow roller body 8 is required, first use an Allen wrench in conjunction with the adjustment mechanism 7. When the adjustment mechanism 7 is running in the forward direction, it will synchronously drive the inner support positioning mechanism 6 to complete the opening and closing motion. When the inner support positioning mechanism 6 is closed, the hollow roller body 8 will be sleeved on the outside of the inner support positioning mechanism 6.

[0032] S2. Use the Allen wrench again to control the adjustment mechanism 7 to rotate in the reverse direction. The adjustment mechanism 7 will synchronously drive the inner support positioning mechanism 6 to complete the opening movement. At this time, the inner support positioning mechanism 6 is stably supported inside the hollow roller body 8 and automatically finds the center inside the hollow roller body 8.

[0033] S3. After the hollow roller body 8 is positioned, the lifting mechanism 2 is started. At this time, the lifting mechanism 2 will simultaneously drive the positioning component 3 and the grinding component 4 to rise, and drive the upper surface of the grinding component 4 to fit against the outer wall of the hollow roller body 8. After the above steps are completed, the stepper motor 209 is started.

[0034] S4. When the stepper motor 209 starts or synchronously drives the upper synchronization mechanism 5 to operate and the grinding component 4 to rotate, when the lower bevel gear disk 503 in the synchronization mechanism 5 rotates, it will simultaneously drive several inner support positioning mechanisms 6 and several adjustment mechanisms 7 to rotate at the same time. At this time, the hollow roller body 8 will also rotate simultaneously with the inner support positioning mechanism 6. The rolling surface of the hollow roller body 8 will be in contact with the upper surface of the grinding disc body 404 for grinding.

[0035] S5. The diameter of several bevel gears 507 is smaller than that of the lower bevel gear disk 503, so the rotation speed of several bevel gears 507 will be faster than that of the lower bevel gear disk 503. Since the upper bevel gear disk 5010 is fixed, when the lower bevel gear disk 503 drives several bevel gears 507, several inner support positioning mechanisms 6 and several adjustment mechanisms 7 to rotate, several bevel gears 507, several inner support positioning mechanisms 6 and several adjustment mechanisms 7 will also complete the revolution, thereby accelerating the grinding of the outer surface of the hollow roller body 8.
