Description

Technical Field

[0001] The utility model relates to the technical field of bearing ring grinding, in particular to a bearing ring grinding device for wind power generation. Background Art

[0002] Bearing ring grinding is a key process in bearing manufacturing, and its quality and efficiency directly impact the bearing's ultimate performance. Its primary purpose is to remove excess material from the workpiece surface, improving its surface roughness and precision to meet the requirements for bearing assembly and operation. Wind turbine bearings, a type of bearing used in wind turbine installations, are subject to harsh operating environments, high maintenance costs, and a high lifespan requirement.

[0003] The utility model with announcement number CN219617312U discloses a bearing ring grinding device. When in use, the cylinder is started, and the cylinder drives the corresponding two limit blocks and two fixed blocks to slide relative to each other in the two limit grooves, and finally the four buffer blocks limit the inner ring of the bearing to be processed, so that the device can be suitable for bearing rings of various specifications and sizes. While effectively fixing the inner ring of the bearing to be processed, it can also avoid its deviation and avoid damage to its interior when fixing, further ensuring the safety of the inner ring of the bearing to be processed during processing.

[0004] However, when the above-mentioned device is in use, it only relies on four buffer blocks to squeeze the inner wall of the ring to fix it, and does not have a strong anti-slip ability. During processing, the bearing is likely to fall off the buffer block, resulting in loss of the fixing effect. In particular, bearings used for wind power generation are usually large in size. If they are only fixed by relying on the inner wall support, the ring is likely to slide, deviate or even fall off during processing. Therefore, in response to the above problem, a bearing ring grinding device for wind power generation is proposed. Utility Model Content

[0005] The technical problem to be solved by the present invention is to provide a bearing ring grinding device for wind power generation, which fixes the bearing ring by moving an anti-slip clamp outward to press against the inner wall of the ring, so as to drive the ring to rotate and complete the grinding. In the anti-slip clamp, the L-shaped plate is in direct contact with the ring, and the horizontal plate part on the upper side can effectively prevent the ring from falling off. In addition, a clamping threaded rod is provided on the L-shaped plate, which can drive the bottom pressure plate to press the bearing ring when rotating, so that it fits tightly with the rotating tray to avoid the ring from sliding or shifting during grinding. This solves the technical problem in the prior art that the fixing measures for the grinding ring are not stable enough, especially the technical problem that the ring is prone to sliding, shifting or even falling off during processing when the ring is larger in size.

[0006] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0007] A bearing ring grinding device for wind power generation comprises a base plate, on which a rotating tray connected in rotation is provided, the rotating tray is provided with a plurality of sliding grooves and an anti-slip clamp for clamping and fixing the bearing ring, wherein the anti-slip clamp comprises a convex sliding block, on which an L-shaped plate is provided, a clamping threaded rod is threadedly connected to the L-shaped plate, and a pressure piece is rotatably connected to the bottom end of the clamping threaded rod, which is fixed by the anti-slip clamp by moving it outward to press against the inner wall of the ring, so as to drive the ring to rotate and complete the grinding. In the anti-slip clamp, the L-shaped plate is in direct contact with the ring, and the horizontal plate part on its upper side can effectively prevent the ring from falling off, and a clamping threaded rod is provided on the L-shaped plate, which can drive the bottom pressure piece to press the bearing ring when rotating, so that it fits tightly with the rotating tray, thereby preventing the ring from sliding or deflecting during grinding.

[0008] In addition, a cooperating clamp driving mechanism is provided to drive the anti-slip clamp to slide, a tray driving mechanism to drive the rotating tray to rotate, and a grinding mechanism to grind the bearing ring.

[0009] In one possible implementation, the L-shaped plate is embedded with an outwardly protruding anti-slip pad layer, which can increase the friction between the L-shaped plate and the ring, improve the fixing effect, and also protect the ring. The outer surface of the anti-slip pad layer is fixedly provided with a number of vertically arranged anti-slip ridges. This structure can further enhance the friction between the anti-slip pad layer and the ring. At the same time, a locking handwheel is fixedly connected to the top of the tightening threaded rod, which facilitates the staff to rotate the tightening threaded rod.

[0010] In one possible implementation, the clamp driving mechanism includes a fixed outer cylinder, in which a movable inner cylinder is slidably arranged, and a plurality of transmission rods are hinged on the movable inner cylinder, and the end of the transmission rod away from the movable inner cylinder is hinged to the convex slider. When the movable inner cylinder moves up and down in the fixed outer cylinder, the anti-slip clamp can be pushed and pulled by the transmission rod to slide in the sliding groove, thereby completing the fixed installation of rings of different sizes.

[0011] In one possible implementation, an adjusting threaded rod is passed through the movable inner cylinder and is threadedly connected to it. The bottom end of the adjusting threaded rod is rotatably connected to the bottom of the fixed outer cylinder, and the top end of the adjusting threaded rod is fixedly connected to an adjusting handwheel. When the adjusting threaded rod is rotated by the adjusting handwheel, the movable inner cylinder will move up and down under the action of the threaded engagement transmission, thereby driving the anti-slip clamp to slide.

[0012] In one possible implementation, a rotating connecting shaft is fixedly provided at the center of the lower end surface of the rotating tray, which is rotatably connected to the base plate via the rotating connecting shaft. The tray driving mechanism includes a driving motor, an output shaft end of which is fixedly connected to a driving wheel, and a bottom end of the rotating connecting shaft is fixedly connected to a driven wheel. The driving wheel and the driven wheel are connected via a transmission belt. When the ring is fixedly installed and ground, the driving motor drives the driving wheel. With the cooperation of the transmission belt and the driven wheel, the rotating tray can be driven to rotate as a whole, and finally the ring is driven to rotate for grinding.

[0013] In one possible implementation, the grinding mechanism includes a bracket, on which a slide is fixedly provided, a sliding rod is slidably provided in the slide, a grinding head is fixedly provided at the front end of the sliding rod, and the grinding head can be used to complete the grinding of the ring, and the sliding rod can slide in the slide to adjust the working position of the grinding head to adapt to the grinding of rings of different sizes.

[0014] In one possible implementation, a mating end piece is fixedly provided at the rear end of the sliding rod, and a tension spring is sleeved on the rear part of the sliding rod. The two ends of the tension spring are fixedly connected to the mating end piece and the slide cylinder respectively. Based on the above structural form, the tension spring can apply tension to pull the mating end piece, so that the sliding rod maintains a tendency to slide forward, so that the grinding head can maintain contact with the ring to ensure the grinding effect.

[0015] In one possible implementation, the cross-section of the sliding groove is convex, and its size is consistent with the cross-sectional size of the convex slider. The above-mentioned structural form can prevent the convex slider from falling out of the sliding groove, and can also ensure that the convex slider is not prone to shaking when sliding.

[0016] In summary, the present invention has the following beneficial technical effects:

[0017] The clamp driving mechanism drives the anti-slip clamp to move outward against the inner wall of the ferrule to fix it, so as to drive the ferrule to rotate and complete the grinding. In the anti-slip clamp, the L-shaped plate is used to directly contact the inner wall of the ferrule, and the ferrule is fixed by squeezing and friction. The horizontal plate part on the upper side of the L-shaped plate can play a blocking role, effectively preventing the ferrule from falling off.

[0018] In addition, a clamping threaded rod is provided on the L-shaped plate, which can drive the bottom pressure plate to move downward and gradually compress the bearing ring when rotating, so that the bearing ring can fit tightly with the rotating tray, preventing the ring from sliding or offsetting during grinding, and improving the stability of the ring rotation during the grinding process.

[0027] The technical solution in the embodiments of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0028] like Figure 1 - Figure 3The cam 32 is provided with a plurality of sliding grooves 21, and an anti-slipping clamp 3 is provided on the cam 32 for clamping and fixing the bearing ring. The anti-slipping clamp 3 includes a convex sliding block 31, on which an L-shaped plate 32 is provided, and a pressing threaded rod 33 is threadedly connected to the L-shaped plate 32. The bottom end of the pressing threaded rod 33 is rotatably connected to a pressing piece 34, and the anti-slipping clamp 3 is fixed by moving the anti-slipping clamp 3 outward against the inner wall of the ring, so as to drive the ring to rotate and complete the grinding. In the anti-slipping clamp 3, the L-shaped plate 32 is in direct contact with the ring, and the horizontal plate part on the upper side can effectively prevent the ring from falling off, and the pressing threaded rod 33 is provided on the L-shaped plate 32, which can drive the pressing piece 34 at the bottom to press the bearing ring when rotating, so that it fits tightly with the rotating tray 2, thereby preventing the ring from sliding or deflecting during grinding.

[0029] In addition, a cooperating clamp driving mechanism 4 is provided for driving the anti-slip clamp 3 to slide, a tray driving mechanism 5 for driving the rotating tray 2 to rotate, and a grinding mechanism 6 for grinding the bearing ring.

[0030] like Figure 3 As shown, the L-shaped plate 32 is embedded with an outwardly protruding anti-skid pad 35. The anti-skid pad 35 can increase the friction between the L-shaped plate 32 and the ring, improve the fixing effect, and also protect the ring. The outer surface of the anti-skid pad 35 is fixedly provided with a plurality of vertically arranged anti-skid ridges 351. This structure can further enhance the friction between the anti-skid pad 35 and the ring. At the same time, the top of the tightening threaded rod 33 is fixedly connected with a locking handwheel 331, which is convenient for the staff to rotate the tightening threaded rod 33.

When the movable inner cylinder 42 moves up and down in the fixed outer cylinder 41, the anti-slip clamp 3 can be pushed and pulled to slide in the sliding groove 21 through the transmission rod 43, thereby completing the fixed installation of rings of different sizes; in addition, an adjusting threaded rod 44 is threadedly connected to the movable inner cylinder 42, and the bottom end of the adjusting threaded rod 44 is rotatably connected to the bottom of the fixed outer cylinder 41, and the top of the adjusting threaded rod 44 is fixedly connected to an adjusting handwheel 45. When the adjusting threaded rod 44 is rotated by the adjusting handwheel 45, the movable inner cylinder 42 will move up and down under the action of the threaded engagement transmission, thereby driving the anti-slip clamp 3 to slide.

[0032] like Figure 4 - Figure 5As shown, a rotating connecting shaft 22 is fixedly provided at the center of the lower end surface of the rotating tray 2, which is rotatably connected to the base plate 1 through the rotating connecting shaft 22. The tray driving mechanism 5 includes a driving motor 51, an output shaft end of which is fixedly connected to a driving wheel 52, and a driven wheel 53 is fixedly connected to the bottom end of the rotating connecting shaft 22. The driving wheel 52 and the driven wheel 53 are connected by a transmission belt 54. When the ring is fixedly installed and ground, the driving motor 51 works to drive the driving wheel 52. With the cooperation of the transmission belt 54 and the driven wheel 53, the rotating tray 2 can be driven to rotate as a whole, and finally the ring is driven to rotate for grinding.

The grinding head 64 can be used to complete the grinding of the ring, and the sliding rod 63 can slide in the slide 62 to adjust the working position of the grinding head 64 to adapt to the grinding of rings of different sizes.

[0034] In addition, a mating end piece 65 is fixedly provided at the rear end of the sliding rod 63, and a tension spring 66 is sleeved on the rear part of the sliding rod 63. The two ends of the tension spring 66 are respectively fixedly connected to the mating end piece 65 and the slide cylinder 62. Based on the above structural form, the tension spring 66 can apply tension to pull the mating end piece 65, so that the sliding rod 63 maintains a tendency to slide forward, so that the grinding head 64 can maintain contact with the ring to ensure the grinding effect.

[0035] like Figure 3 - Figure 4 As shown, the cross-section of the sliding groove 21 is convex, and its size is consistent with the cross-sectional size of the convex slider 31. The above-mentioned structural form can prevent the convex slider 31 from falling out of the sliding groove 21, and can also ensure that the convex slider 31 is not prone to shaking when sliding.

[0036] The use principle and use process of this utility model:

[0037] The anti-slip clamp 3 is driven by the clamp driving mechanism 4 to expand and move against the inner wall of the ring to fix it, so as to drive the ring to rotate and complete the grinding. In the anti-slip clamp 3, the L-shaped plate 32 is used to directly contact the inner wall of the ring, and the ring is fixed by extrusion and friction, and the horizontal plate part on the upper side of the L-shaped plate 32 can play a blocking role, effectively preventing the ring from falling off. At the same time, a clamping threaded rod 33 is provided on the L-shaped plate 32, which can drive the bottom pressure plate 34 to move downward and gradually press the bearing ring when rotating, so that the bearing ring can fit tightly with the rotating tray 2, avoiding the ring from sliding or offsetting during grinding, and improving the stability of the ring rotation during the grinding process.

[0038] In addition, an outwardly protruding anti-skid pad layer 35 is embedded in the L-shaped plate 32. The anti-skid pad layer 35 can increase the friction between the L-shaped plate 32 and the ring, improve the fixing effect, and also protect the ring. The outer surface of the anti-skid pad layer 35 is fixed with several vertically arranged anti-skid ridges 351. This structure can further enhance the friction between the anti-skid pad layer 35 and the ring.

[0039] In the above scheme, the working principle of the clamp driving mechanism 4 is specifically manifested as follows: when the adjusting threaded rod 44 is rotated by adjusting the hand wheel 45, the movable inner cylinder 42 will move up and down under the action of the threaded engagement transmission. When the movable inner cylinder 42 moves up and down in the fixed outer cylinder 41, the anti-slip clamp 3 can be pushed and pulled by the transmission rod 43 to slide in the sliding groove 21, thereby completing the fixed installation of rings of different sizes.
