Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, specifically to a high-grinding processing equipment for bearing rings. Background Technology

[0002] High-precision grinding equipment for bearing rings is a specialized machine tool used to perform high-precision grinding on key surfaces such as the inner hole, outer circle, and end face of bearing rings to correct their dimensional accuracy, shape accuracy, and surface roughness, ensuring that the bearing can achieve low friction, high rotational accuracy, and long service life after subsequent assembly.

[0003] Existing high-precision grinding equipment for bearing rings suffers from insufficient flexibility in adjusting the grinding position and method during the high-precision grinding process. This makes it difficult to adapt to the processing needs of bearing rings of different specifications. Most equipment has fixed grinding component positions or limited adjustment ranges, allowing only a single grinding method for bearing rings of specific sizes. When switching grinding positions and methods is required for inner and outer rings, or for rings of different diameters or thicknesses, other equipment must be used, resulting in low processing efficiency and an inability to meet diverse production demands. Furthermore, existing equipment is susceptible to vibration during processing, severely reducing grinding accuracy. During operation, the motor, grinding components, and other parts generate vibration. The lack of effective damping structures allows vibration to be directly transmitted to the clamping and grinding mechanisms, leading to unstable bearing ring clamping and grinding trajectory deviation. This results in increased dimensional errors and excessive surface roughness in the processed rings, failing to meet high-precision processing standards, affecting the subsequent assembly and use performance of the bearing rings, and increasing the rate of defective products.

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] This utility model discloses a high-grinding machining equipment for bearing rings.

[0023] This utility model provides, for example Figure 1-4 The high-grinding machining equipment for bearing rings shown includes a base 1. The top two ends of the base 1 are respectively fixedly connected to a U-shaped support seat 2 and a support platform 3 through a buffer mechanism. The bottom of the inner side wall of the U-shaped support seat 2 is fixedly connected to a connecting chamber 4. The top of the connecting chamber 4 is rotatably connected to a clamping platform 5. A motor 6 is fixedly connected inside the cavity of the connecting chamber 4. One end of the motor 6 is fixedly connected to the bottom of the clamping platform 5. The top two ends of the clamping platform 5 are fixedly connected to arc-shaped limiting plates 7 through a drive mechanism. A first hydraulic rod 8 is fixedly connected to the top of the U-shaped support base 2. One end of the first hydraulic rod 8 passes through the top of the U-shaped support base 2 and is fixedly connected to a positioning plate 9. The positioning plate 9 corresponds to the center position of the clamping table 5. An adjustable grinding device 10 is fixedly connected to one side wall of the positioning plate 9, and a first trapezoidal spray plate 11 is fixedly connected to the other side wall of the positioning plate 9. A movable grinding device 12 is fixedly connected to both ends of the top of the support table 3. A clamping assembly 13 is fixedly connected to the top of the support table 3. A second trapezoidal spray plate 14 is fixedly connected to both ends of the top of the clamping assembly 13. A display controller 15 is fixedly connected to the side wall of the base 1. The set buffer mechanism absorbs the vibration generated during the processing and reduces the impact of vibration on the processing. To improve grinding accuracy and processing stability, a U-shaped support base 2 is used to provide mounting support for components such as the clamping table 5 and the first hydraulic rod 8, ensuring precise positioning of each component. A support platform 3 provides an installation platform for the mobile grinding device 12 and the clamping assembly 13, enabling simultaneous processing at multiple stations. A connecting compartment 4 provides protection and installation space for the motor 6, preventing contamination from grinding debris. The clamping table 5 provides a platform for placing and rotating the bearing rings, suitable for grinding the ring's annular structure. The motor 6 drives the clamping table 5 to rotate at a uniform speed, ensuring even grinding of the outer circumference of the rings and guaranteeing consistent ring wall thickness. A drive mechanism drives the arc-shaped limit switch. The clamping plate 7 moves synchronously to achieve stable clamping of bearing rings of different diameters. The arc-shaped limiting clamping plate 7 conforms to the outer curved surface of the ring, increasing the clamping contact area and preventing deformation of the ring during clamping. It also prevents displacement during ring rotation. The first hydraulic rod 8 drives the positioning plate 9 to rise and fall vertically, precisely adjusting the distance between the adjustable grinding device 10 and the clamping table 5 to adapt to the grinding needs of bearing rings of different thicknesses. The positioning plate 9 ensures that the adjustable grinding device 10 and the clamping table 5 are coaxial, preventing grinding position deviation. The adjustable grinding device 10 allows for flexible adjustment of the grinding position, grinding either the outer or inner ring. The first trapezoidal spray plate 11 and the second trapezoidal spray plate 12... The spray plate 14 sprays cooling airflow to cool the grinding area, preventing the bearing ring from deforming due to high temperature, and blows away grinding debris. The movable grinding device 12 can move horizontally to achieve precise grinding of the bearing ring end face or specific areas, expanding the processing function of the equipment. The clamping component 13 is used to assist in fixing the bearing ring, which is especially suitable for the positioning requirements when grinding the bearing ring end face. The display controller 15 displays grinding parameters (speed, pressure, temperature, etc.) in real time, which makes it easy for operators to accurately control the processing process and improves the convenience of operation. This solves the problems of inconvenient adjustment of grinding position and method in existing bearing ring high-grinding processing equipment, and the vibration that easily affects the accuracy during processing.

[0024] To absorb processing vibrations and improve equipment operational stability, such as Figure 1 and 2As shown, the buffer mechanism includes a friction seat 16, a friction sleeve 17, a hydraulic spring damper 18, and a polyurethane support ring 19. Friction seats 16 are fixedly connected to both ends of the top of the base 1, and friction sleeves 17 are fixedly connected to the bottom of the U-shaped support seat 2 and the support platform 3. The friction sleeves 17 at both ends are rubbed against the friction seats 16. Hydraulic spring dampers 18 are fixedly connected to the periphery of the cavity of each friction seat 16, and the top of each hydraulic spring damper 18 is fixedly connected to the bottom of the corresponding friction sleeve 17. A polyurethane support ring 19 is fixedly connected between the friction seats 16 and the friction sleeves 17. By utilizing the frictional engagement between the friction seats 16 and the friction sleeves 17, some vibration energy is consumed through friction, initially buffering the vibration. The hydraulic spring dampers 18 absorb the vertical vibration impact force through elastic deformation, preventing vibration from being transmitted to the clamping platform 5 or the clamping assembly 13, ensuring the processing accuracy of the sleeve. The polyurethane support ring 19 buffers horizontal vibration, while reducing wear on the friction seats 16 and friction sleeves 17, extending the service life of the buffer mechanism, and further improving the operational stability of the equipment.

[0025] To achieve stable clamping of bearing rings of different diameters, such as Figure 1 and 2 As shown, the driving mechanism includes a bidirectional screw 20, a threaded sleeve 21, a sliding opening 22, and an operating handle 23. The bidirectional screw 20 is rotatably connected inside the cavity of the clamping table 5. The walls of both ends of the bidirectional screw 20 are threadedly connected to the threaded sleeve 21. Sliding openings 22 are provided at both ends of the clamping table 5. The arc-shaped limiting plates 7 at both ends pass through the sliding openings 22 and are fixedly connected to the side walls of the corresponding threaded sleeves 21. One end of the bidirectional screw 20 passes through the side wall of the clamping table 5 and is fixedly connected to the operating handle 23. When the bidirectional screw 20 rotates, it drives the threaded sleeves 21 at both ends to move closer or further away synchronously, thereby adjusting the spacing of the arc-shaped limiting plates 7 to accommodate different diameter rings. The threaded sleeves 21 convert the rotational motion of the screw into linear motion, resulting in high transmission accuracy and ensuring precise clamping position. The sliding openings 22 provide a sliding trajectory for the arc-shaped limiting plates 7 to prevent plate offset. The operating handle 23 increases the force application area of ​​the hand, making it easy for operators to manually adjust without additional tools, thus improving the convenience of clamping and adjustment.

[0026] To flexibly adjust the grinding position and method, and adapt to the grinding needs of multiple parts of the raceway, such as Figure 1 and 2As shown, the adjustable grinding device 10 includes a first electric guide rail 24, with a dry grinding roller device 25 fixedly connected to the moving end of the first electric guide rail 24. Both ends of the movable grinding device 12 include a second electric guide rail 26, with a dry grinding disc device 27 fixedly connected to the moving end of the second electric guide rail 26. The first electric guide rail 24 drives the dry grinding roller device 25 to move vertically, which can precisely adjust the contact position between the grinding roller and the ring, adapting to the grinding needs of different heights on the outer circumference of the ring. The dry grinding roller device 25 adopts a roller grinding structure, which is suitable for continuous grinding of the curved surface of the outer circumference of the ring, ensuring a smooth grinding surface. The second electric guide rail 26 drives the dry grinding disc device 27 to move horizontally, which can adjust the distance between the grinding disc and the end face of the ring, adapting to the grinding of the end face or stepped surface of the ring. The dry grinding disc device 27 adopts a disc grinding structure, which has high grinding efficiency and is suitable for the grinding needs of the ring's surface. The two work together to achieve flexible grinding of multiple parts and multiple methods of the ring.

[0027] To assist in fixing the raceway and ensure the grinding accuracy of the end face, such as Figure 1-3 As shown, the clamping assembly 13 includes a U-shaped clamping platform 28. A second hydraulic rod 29 is fixedly connected to one end of the top of the U-shaped clamping platform 28. One end of the second hydraulic rod 29 passes through the top of the U-shaped clamping platform 28 and is fixedly connected to an arc-shaped clamping plate 30. The U-shaped clamping platform 28 provides lateral support for the ring, which is suitable for the placement requirements during ring end face grinding. The second hydraulic rod 29 drives the arc-shaped clamping plate 30 to rise and fall vertically, which can precisely adjust the clamping pressure and avoid ring deformation. The arc-shaped clamping plate 30 fits the outer circumferential curved surface of the ring, increasing the clamping contact area and ensuring no deviation during ring end face grinding, thereby improving end face grinding accuracy.

[0028] To efficiently cool the grinding area and prevent high-temperature deformation of the bearing ring, such as... Figure 1 , 2 As shown in Figure 4, a cooling fan device 31 is fixedly connected to one end of the cavity of the base 1. The three output pipe ends of the cooling fan device 31 are fixedly connected to the inlets of the first trapezoidal spray plate 11 and the second trapezoidal spray plates 14 at both ends, respectively. The first trapezoidal spray plate 11 and the second trapezoidal spray plates 14 at both ends are trapezoidal hollow plates, and multiple air outlets 32 are opened on the inclined surface. The cooling fan device 31 provides a continuous and stable cooling airflow to the first trapezoidal spray plate 11 and the second trapezoidal spray plate 14 to ensure the cooling effect. The multi-output pipe end design enables a single fan to supply air to multiple spray plates at the same time, simplifying the cooling system structure. The trapezoidal hollow plate structure allows the spray plate to fit the inclined angle of the grinding area. The air outlets 32 accurately guide the cooling airflow to the grinding part, increasing the coverage of the cooling airflow. The multiple air outlets 32 are evenly distributed to ensure that the cooling airflow is sprayed evenly, avoiding local high temperature causing deformation of the ring, and blowing away grinding debris to prevent the debris from affecting the grinding surface quality.
