Description

Technical Field

[0001] The invention relates to the technical field of bearing processing, and in particular to a grinding device for bearing production. Background Art

[0002] As an indispensable key basic component in mechanical equipment, bearings are widely used in many industrial fields, such as automobile manufacturing, aerospace, mechanical processing, power equipment, etc. The quality of their performance directly affects the operating accuracy, stability and service life of the entire mechanical equipment. In the production and manufacturing process of bearings, the grinding process is an extremely important link. The quality of the outer ring surface of the bearing ring has a decisive influence on the assembly accuracy, rotation flexibility and load-bearing capacity of the bearing. Through grinding, burrs, oxide layers and other defects generated on the surface of the bearing ring during the early processing process can be removed, and the surface roughness can be controlled within an appropriate range to meet the strict requirements for bearing performance in different application scenarios.

[0003] Traditional bearing grinding devices are often designed for bearing rings within a specific diameter range. When faced with bearing rings of different diameters, it usually takes a lot of time to adjust the equipment or replace the adapter parts. For example, the position of the drive structure and grinding tool of some grinding devices is fixed. When grinding a bearing ring with a larger or smaller diameter, the drive structure may not be able to effectively drive the bearing ring to rotate, or the grinding tool may not fit well with the outer ring surface of the bearing ring for grinding. This leads to low production efficiency and increases production costs and the complexity of equipment management.

[0004] During the grinding process, due to the lack of an effective adaptive adjustment mechanism, the traditional device is prone to separation between the bearing ring and the drive component due to vibration, external force, etc. Once this happens, not only will the grinding work be interrupted, affecting production efficiency, but it may also cause uneven grinding of the bearing ring surface, local over-grinding or inadequate grinding, which will in turn affect the quality of the bearing ring, reduce the product qualification rate, and fail to meet the needs of high-quality bearing production.

[0005] The structural design of some traditional grinding devices makes it difficult to ensure that the grinding tool and the bearing ring always maintain precise contact and a relatively stable grinding posture, which makes it very difficult to control the precision indicators such as the roughness of the outer ring surface of the bearing ring within the ideal range. Especially for some special bearing products with high precision requirements, traditional grinding devices are difficult to meet the corresponding process requirements, which limits the application and development of bearing products in high-end fields.

[0006] As the requirements for bearing quality in industrial production continue to increase, the industry has also tried a variety of methods to improve traditional bearing grinding devices. For example, by adding adjustable clamps to fix bearing rings of different diameters, but this method can only solve the problem of fixing the bearing rings, and has limited effect on improving the stability and grinding accuracy during the grinding process; some replace grinding heads of different specifications to adapt to bearing rings of different diameters, but frequent replacement of grinding heads is cumbersome and easily affects the grinding quality due to factors such as installation errors. Overall, these improvement measures have not been able to comprehensively and effectively solve the many problems of traditional bearing grinding devices in terms of adaptability, stability, and grinding accuracy. There is an urgent need for a more complete and efficient bearing production grinding device to meet the development needs of the modern bearing manufacturing industry.

[0007] To sum up, under such background, it is of great practical significance to develop a grinding device for bearing production that can adapt to bearing rings of various diameters, ensure the stability of the grinding process and effectively improve the grinding accuracy. Summary of the invention

[0008] The present invention relates to a grinding device for bearing production, which aims to solve the problems of poor adaptability of existing grinding devices when facing bearing rings of different diameters and possible instability during the grinding process, and realize efficient and stable grinding operations that are adaptable to bearing rings of various specifications.

[0009] Overall structure of the device The device comprises a horizontally placed base, with shaft frames symmetrically arranged at both ends of the top of the base, two driven rotating rods hinged on the top of the shaft frames, and a rolling bearing ring placed on the top of the driven rotating rod. A special grinding component is arranged above the bearing ring to grind the outer ring surface of the bearing ring.

[0010] Grinding component composition and principle Basic structure The grinding assembly includes a lifting plate located above the bearing ring, which is rectangular in shape, with sliding rods inserted in the four corners. A driving frame is provided at the bottom of the sliding rod, and a driving wheel is hingedly connected to the lower end of the driving frame on the adjacent side. There are two driving wheels in total, and their outer circumferences are tightly abutted against the outer circumference of the bearing ring. The same mounting plate is provided at the top of the sliding rod, and two connecting frames are provided on one side of the top of the mounting plate. A supporting frame is installed on the top of the connecting frame, and an adjusting shaft is hingedly connected to the top of the supporting frame. A roller frame is sleeved at the middle position of the outer circumference of the adjusting shaft, and a grinding roller for grinding the outer circumference of the bearing ring is hingedly connected to the lower end of the roller frame, and the outer circumference of the grinding roller is also abutted against the outer circumference of the bearing ring.

[0011] Adjustment components The adjustment assembly consists of a worm gear sleeved on the end of the adjustment shaft, a worm vertically meshed with the worm gear, and a worm hinged on the top of the support frame. A handwheel is coaxially arranged on the top of the worm gear. By turning the handwheel, the worm gear can be driven to rotate, and then the worm gear meshed with it drives the adjustment shaft to rotate, and finally the angle of the grinding roller can be adjusted to adapt to bearing rings of different diameters, ensuring that the grinding roller can have good contact with the outer peripheral surface of bearing rings of different specifications, thereby ensuring the grinding effect.

[0012] Combined transmission components The combined transmission assembly includes a motor arranged transversely on the top of the mounting plate. The motor output shaft and the end of the driving wheel are both sleeved with a first pulley, and these first pulleys are sleeved with the same first transmission belt, so as to realize the transmission of the motor to the driving wheel. At the same time, a driven shaft is also installed on the top of the mounting plate, and the driven shaft and the end of the grinding roller are both sleeved with a second pulley, and the second pulley is sleeved with the same second transmission belt, and the end of the motor output shaft is sleeved with a first gear, and the end of the driven shaft is sleeved with a second gear, and the second gear is meshed with the first gear. Through such a transmission structure, it can be ensured that the driving wheel and the grinding roller can rotate synchronously when the motor is started, and the coordination and stability of the grinding work are guaranteed.

[0013] Other auxiliary structures and functions A spring is sleeved on the outer surface of the slide bar near the top of the drive frame and the bottom of the lifting plate. In the initial state, the lifting plate is in a high position to facilitate the placement of the bearing ring. When the bearing ring is placed, the vertical cylinder on the gantry set on the top of the base pushes the top rod at its output end to lower the lifting plate. During the descent process, the spring relies on its own elastic force to play a role. No matter how the diameter of the bearing ring changes, the drive wheel can always be closely abutted against the outer surface of the bearing ring, avoiding the separation of the bearing ring and the drive wheel due to vibration and other factors during grinding, ensuring that the grinding work is carried out continuously and stably, so as to adapt to bearing rings of various diameters for efficient grinding.

[0014] The grinding device of the present invention can flexibly cope with bearing rings of different diameters through the coordinated cooperation of the above-mentioned structures, realize stable and high-quality outer ring surface grinding operations, and effectively improve the efficiency and quality of the grinding process in the bearing production process.

[0015] Beneficial effects of the present invention: 1. Improve the adaptability to bearing rings of different diameters The springs on the slide rods in the device play a key role. Before the grinding work, after the bearing rings of different diameters are placed, the lifting plate is controlled to descend by the cylinder, and the spring can be automatically adjusted according to the diameter of the bearing ring. For example, for a bearing ring with a larger diameter, the drive wheel will be stretched outward a certain distance. At this time, the spring is compressed, and its elastic force can still be used to reverse the drive wheel and the outer peripheral surface of the bearing ring. When facing a bearing ring with a smaller diameter, the spring can push the drive wheel to contact the bearing ring well through its own stretching tendency. This adaptive adjustment mechanism relying on the spring elastic force allows the grinding device to adapt to bearing rings of various diameters, greatly broadening the scope of application of the device. There is no need to frequently replace or adjust complex components for bearing rings of different diameters, effectively improving production efficiency, reducing production costs, and meeting the diverse needs of bearing production and grinding.

[0016] Grinding roller angle adjustable The adjustment assembly set at one end of the adjustment shaft provides another strong guarantee for adapting to bearing rings of different diameters. The operator can turn the hand wheel to drive the adjustment shaft to rotate through the meshing transmission of the worm and the worm wheel, thereby changing the angle of the grinding roller. For example, when processing bearing rings with larger diameters, adjust the grinding roller to a suitable inclination angle so that its outer peripheral surface can better fit the outer ring surface of the bearing ring for grinding; for bearing rings with smaller diameters, adjust the grinding roller angle accordingly to achieve sufficient and effective grinding contact. Through this flexible angle adjustment method, the device's ability to adapt to bearing rings of different sizes is further enhanced, ensuring accurate and uniform grinding effects in various specifications.

[0017] 2. Ensure the stability and sustainability of grinding work During the entire grinding process, the presence of the spring ensures that the drive wheel and the bearing ring always maintain a close contact state. Even if vibration, external force interference, etc. occur during grinding, the stable elastic force provided by the spring can effectively prevent the bearing ring from separating from the drive wheel, ensuring that the bearing ring can rotate continuously and stably. At the same time, the combined transmission assembly ensures that the drive wheel and the grinding roller can rotate synchronously. The two work together to allow the grinding roller to grind the outer surface of the bearing ring uninterruptedly without problems such as interruption or uneven grinding caused by uncoordinated transmission. This stability and continuity not only helps to improve the grinding quality and reduce the defective rate, but also increases the grinding output per unit time, which has a positive effect on the overall efficiency and quality improvement of bearing production.

[0018] 3. Improve grinding quality and precision Due to the above-mentioned advantages in adaptability and stability, the grinding device can keep the grinding roller and the outer ring surface of the bearing ring of different diameters in a good fit and contact state, achieving uniform and sufficient grinding. Both the roughness control of the bearing ring surface and the guarantee of dimensional accuracy can meet high standards. For example, by accurately adjusting the angle of the grinding roller and the stable driving wheel to drive the bearing ring to rotate, the outer ring surface of the bearing ring can be polished to be smoother and flatter, meeting the strict requirements of the bearing production process, laying a solid foundation for the subsequent assembly and use performance of the bearing, and effectively improving the competitiveness of bearing products in the market.

[0019] 4. Easy to operate and maintain The structural design of the device is relatively compact and reasonable, and the operation of each component is relatively intuitive and simple. For example, the grinding roller angle can be adjusted by turning the hand wheel, which is easy to operate; the lifting plate is controlled by the cylinder, and the operation is stable and reliable. Moreover, this structure is also convenient for daily maintenance. Each key transmission component and adjustment component are easy to check, repair and replace, which reduces the difficulty and cost of equipment maintenance, helps to extend the service life of the equipment, and improves the comprehensive use efficiency of the equipment, so that enterprises can use the grinding device more efficiently and economically in the bearing production process.

[0026] Example 1 See also Figures 1 to 6 1. Initial preparation of the device and installation of components Installation of base and related supporting components First, the horizontally placed base 1 is placed steadily on a suitable work site to ensure that its installation plane is horizontal and stable, providing a stable basic support for the entire grinding device. Then, the shaft frame 2 is symmetrically installed at both ends of the top of the base 1 to ensure that the shaft frame 2 is firmly installed and its position accuracy meets the requirements for the subsequent placement and rotation of the bearing ring 4.

[0027] Assembly and installation of grinding components Lifting plate and slide bar part: Place the rectangular lifting plate 8 at the predetermined position so that it is located above the bearing ring 4. Then, slide the four slide bars 9 into the four corners of the lifting plate 8 to ensure that the slide bars 9 can slide up and down smoothly in the lifting plate 8. Install the drive frame 11 at the bottom end of the slide bar 9, and install the same drive wheel 12 at the lower end of the drive frame 11 on the adjacent side through a suitable hinged method. A total of two drive wheels 12 are installed, and ensure that the outer peripheral surface of the drive wheel 12 is in a state that it can abut against the outer peripheral surface of the bearing ring 4. After that, install the same mounting plate 10 on the top of the slide bar 9 to connect the entire structure as one.

[0028] Grinding roller and adjustment component part: Install two connecting frames 27 on one side of the top of the mounting plate 10, fix the support frame 24 on the top of the connecting frame 27, and then hinge the adjustment shaft 23 on the top of the support frame 24 so that the adjustment shaft 23 can rotate flexibly. Sleeve the roller frame 22 at the middle position of the outer circumference of the adjustment shaft 23, and install the grinding roller 21 for grinding the outer circumference of the bearing ring 4 at the lower end of the roller frame 22 by hinged connection, and adjust the initial position of the grinding roller 21 so that its outer circumference can naturally abut against the outer circumference of the bearing ring 4. Then install the adjustment component, sleeve the worm wheel 25 on the end of the adjustment shaft 23, make the vertical worm 26 accurately mesh with the worm wheel 25, and hinge the worm 26 on the top of the support frame 24, and finally coaxially install the hand wheel 28 on the top of the worm 26 to facilitate subsequent adjustment operations.

[0029] Combined transmission component part: Install the motor 14 on the top of the mounting plate 10, ensure that the motor 14 is firmly installed and accurately positioned so that its output shaft can rotate smoothly. The first pulley 13 is sleeved on the ends of the output shaft of the motor 14 and the two driving wheels 12, and then the same first transmission belt 15 is sleeved on these first pulleys 13 to establish a transmission connection between the motor 14 and the driving wheels 12. Next, install the driven shaft 18 on the top of the mounting plate 10, and sleeve the second pulley 20 on the ends of the driven shaft 18 and the grinding roller 21, and then sleeve the same second transmission belt 19 on these second pulleys 20, and at the same time, sleeve the first gear 16 on the end of the output shaft of the motor 14, and sleeve the second gear 17 on the end of the driven shaft 18, and ensure that the second gear 17 and the first gear 16 can accurately and smoothly mesh with each other, so as to realize the combined transmission, so that the driving wheel 12 and the grinding roller 21 can rotate synchronously.

[0030] Other auxiliary parts installation Springs 29 are sleeved on the outer circumference of the slide bar 9 near the top of the driving frame 11 and the bottom of the lifting plate 8 to ensure that the springs 29 are installed in place and have appropriate elastic properties. In addition, a gantry 5 is installed on the top of the base 1 to ensure that the gantry 5 has a stable structure. A cylinder 6 is vertically installed on the top of the gantry 5, and a push rod 7 is coaxially installed at the output end of the cylinder 6, so that the push rod 7 can be driven by the cylinder 6 to perform up and down telescopic movements.

[0031] 2. Bearing ring placement and grinding device adjustment Bearing ring placement After the installation and assembly of the above device is completed, the lifting plate 8 is in a high position, leaving enough space for placing the bearing ring 4. The bearing ring 4 to be polished is placed on the top of the driven rotating rod 3 by a suitable handling tool or manual operation, ensuring that the bearing ring 4 can be stably placed on the driven rotating rod 3 and can rotate freely.

[0032] Grinding device adjustment adapter bearing ring Adjustment of the lifting plate descent: Start the cylinder 6, the output end of the cylinder 6 pushes the push rod 7 to move downward, and the push rod 7 acts on the lifting plate 8, so that the lifting plate 8 starts to slide downward along the slide bar 9. In this process, due to the different diameters of the bearing ring 4, the initial position of the driving wheel 12 will be different. When the driving wheel 12 contacts the outer peripheral surface of the bearing ring 4, if the diameter of the bearing ring 4 is large, the driving wheel 12 will be stretched outward. At this time, the spring 29 on the slide bar 9 is compressed, and the spring 29 will generate a reverse elastic force, which acts on the driving frame 11, so that the driving wheel 12 can still be tightly abutted against the outer peripheral surface of the bearing ring 4; on the contrary, if the diameter of the bearing ring 4 is small, the spring 29 can also push the driving wheel 12 to abut tightly against the outer peripheral surface of the bearing ring 4 by relying on its own extension trend. Through this adaptive adjustment of the spring 29, no matter how the diameter of the bearing ring 4 changes, it can ensure that the driving wheel 12 and the outer peripheral surface of the bearing ring 4 always maintain a good abutment state, providing guarantee for the subsequent grinding work and the stable rotation of the bearing ring 4.

[0033] Grinding roller angle adjustment: According to the specific diameter of the bearing ring 4 placed, the angle of the grinding roller 21 is adjusted by turning the hand wheel 28. When the hand wheel 28 is turned, the worm 26 rotates accordingly. Due to the meshing relationship between the worm 26 and the worm wheel 25, the adjusting shaft 23 is driven to rotate. The rotation of the adjusting shaft 23 causes the roller frame 22 and the grinding roller 21 to change the angle around the adjusting shaft 23. For example, for a bearing ring 4 with a larger diameter, by turning the hand wheel 28 clockwise or according to the actual design rotation direction, the grinding roller 21 is gradually adjusted to a relatively inclined angle, so that its outer peripheral surface can better fit the outer ring surface of the bearing ring 4; and for a bearing ring 4 with a smaller diameter, the hand wheel 28 is turned counterclockwise to reduce the angle of the grinding roller 21, ensuring that the grinding roller 21 can fully and effectively contact the outer ring surface of the bearing ring 4, thereby achieving accurate adaptive grinding of bearing rings 4 with different diameters.

[0034] 3. Start and proceed with polishing work Start the motor to achieve synchronous rotation After completing the above adaptation and adjustment of the grinding device and the bearing ring 4, the motor 14 is started. After the motor 14 is started, its output shaft starts to rotate, and through the transmission of the first pulley 13 and the first transmission belt 15, the two driving wheels 12 are driven to rotate synchronously. At the same time, the first gear 16 at the end of the output shaft of the motor 14 and the second gear 17 at the end of the driven shaft 18 are meshed with each other, which will cause the driven shaft 18 to rotate, and then with the help of the transmission of the second pulley 20 and the second transmission belt 19, the grinding roller 21 is driven to rotate synchronously. In this way, the driving wheel 12 and the grinding roller 21 are driven by the motor 14 to achieve synchronous rotation.

[0035] Bearing ring rotation and grinding process As the driving wheel 12 rotates, its outer circumference is in close contact with the outer circumference of the bearing ring 4, which drives the bearing ring 4 to rotate stably on the driven rotating rod 3. At the same time, the outer circumference of the grinding roller 21 is also in close contact with the outer circumference of the bearing ring 4. During the rotation of the bearing ring 4, the grinding roller 21 will continue to grind the outer ring surface of the bearing ring 4. During the entire grinding process, due to the presence of the spring 29, it is ensured that the driving wheel 12 and the bearing ring 4 will not be separated due to vibration, external force and other factors generated during grinding, so that the bearing ring 4 can continue to rotate stably, and the grinding roller 21 can also continue to grind its outer ring surface evenly and efficiently until the preset grinding quality requirements are met.

[0036] 4. Operation after grinding When the grinding of the outer ring surface of the bearing ring 4 is completed and the required surface quality, dimensional accuracy and other requirements are met, the motor 14 is first turned off to stop the driving wheel 12 and the grinding roller 21. Then the cylinder 6 is controlled to retract the push rod 7 upward, driving the lifting plate 8 to rise back to the initial high position along the slide rod 9. At this time, the polished bearing ring 4 can be easily removed from the driven rotating rod 3 to prepare for the grinding of the next bearing ring. This cycle of operation can achieve efficient grinding production of multiple bearing rings.

[0037] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
