Description

Technical Field

[0001] The invention relates to the technical field of wind power generator sets, in particular to a bearing chamber production polishing device with a clamping function. Background Art

[0002] Special bearings for wind turbines Bearings for wind turbines can be roughly divided into three categories, namely yaw bearings, pitch bearings, and transmission system bearings (main shaft and gearbox bearings). Yaw bearings are installed at the connection between the tower and the cabin, and pitch bearings are installed at the connection between the root of each blade and the hub. Each wind turbine equipment uses one set of yaw bearings and three sets of pitch bearings. Some wind turbines below the megawatt level have non-adjustable blades and do not need pitch bearings. For this purpose, the China Patent Network has published a polishing device for the production of wind turbine bearing chambers with the publication number CN115229652B, which includes: a mounting platform, a control terminal, an inner polishing mechanism, a first lifting module, an outer polishing mechanism, a second lifting module, a driving roller, a mounting frame, a pushing module and a limiting roller; the inner polishing mechanism is arranged in the middle of the front side of the top end of the mounting platform along the front-back direction; the first lifting module is arranged at the top end of the mounting platform through a bracket and is located at the left rear of the inner polishing mechanism, and the first lifting module and the control terminal are electrically connected; the outer polishing mechanism is arranged at the lifting end of the first lifting module. The bearing chamber production polishing device with a clamping function can be used for polishing wind turbine bearings of different diameters, and can simultaneously polish multiple surfaces of wind turbine bearings; However, there are still the following disadvantages: the device limits the bearing chamber by rollers when grinding it, and the limiting effect of the rollers themselves is poor. In addition, the rotation of the polishing device during grinding may cause a slight deflection of the bearing chamber itself, thereby affecting the polishing effect; Therefore, the design is highly practical and by providing a limiting part, the bearing chamber can be further clamped after it is clamped and fixed, so that it can be more stable when fixed. During grinding and polishing, the grinding block is inside the bearing chamber, and the surface of the grinding block is in compression contact with the inner wall of the bearing chamber. When the bearing chamber rotates, the bearing chamber will rotate slightly due to its own rapid rotation, thereby affecting its grinding and polishing effect. When the clamping plate contacts the surface of the bearing chamber, the first airbag is squeezed, and when the first airbag is squeezed, the second airbag is expanded, so that the surface of the lateral limiting plate is in contact with the surface of the bearing chamber. A bearing chamber production and polishing device with a clamping function is very necessary. Summary of the invention

During adjustment, the elastic force of the first elastic member can make the surfaces of the two polishing blocks always in contact with the inner wall of the bearing chamber, making the polishing more uniform. By providing a slide rail and a limit plate, the polishing blocks can always be in a horizontal state during adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Furthermore, this embodiment is equipped with a fixing mechanism 3 to fix the inner wall of the bearing chamber when it is being ground and polished, thereby preventing the bearing chamber from moving during grinding and polishing, resulting in a lower smoothness of the polished surface and the need for secondary grinding, which reduces the efficiency during the grinding and polishing process.

[0021] Embodiment 3 See also Figure 1-Figure 7, and on the basis of the first and second embodiments, it is further obtained that: the polishing mechanism 2 includes a fixed frame 210, the bottom surface of the fixed frame 210 is fixedly connected to the top surface of the bottom plate 1, four telescopic devices 201 are fixedly arranged on the inner top surface of the fixed frame 210, and the bottom surfaces of the output ends of the four telescopic devices 201 are fixedly arranged with a lifting plate 202, the bottom surface of the lifting plate 202 is fixedly arranged with a fixed column 203, the bottom surface of the fixed column 203 is fixedly arranged with a mounting plate, the bottom surface of the mounting plate is fixedly arranged with a slide rail 206, and the sliding surface of the slide rail 206 is provided with two limit The bottom surfaces of the two limit plates 208 are fixed with two grinding blocks 207, the surface of the fixed column 203 is slidably sleeved with a sliding frame 204, the bottom surface of the sliding frame 204 is hinged with two connecting rods 205, the inner sides of the two connecting rods 205 are hinged to the left and right sides of the mounting plate respectively, the bottom surfaces of the two connecting rods 205 are hinged to the side surfaces far from the two grinding blocks 207 respectively, the top surface of the sliding frame 204 is fixed with two first elastic members 209, the top surfaces of the two first elastic members 209 are fixedly connected to the bottom surface of the lifting plate 202.

[0022] Furthermore, this embodiment is provided with a polishing mechanism 2, which can be used to polish the bearing chamber after it is clamped and fixed, and before polishing, the two polishing blocks 207 can be controlled to extend into the bearing chamber, and the distance between the two polishing blocks 207 can be adjusted according to the size of the bearing chamber itself, so that there is less restriction during polishing. During adjustment, the elastic force of the first elastic member 209 can ensure that the surfaces of the two polishing blocks 207 are always in contact with the inner wall of the bearing chamber, making the polishing more uniform. The slide rail 206 and the limit plate 208 can ensure that the polishing block 207 is always in a horizontal state during adjustment.

[0023] Working principle: Place the bearing chamber to be polished on the placement plate 304, and initially fix the bearing chamber by setting a suction cup. Open the telescopic device 201 to make the polishing block 207 move downward, and the polishing block 207 will contact the inner wall of the bearing chamber when it moves downward. The connecting rod 205 and the first elastic member 209 can make the far side of the two polishing blocks 207 squeeze and contact the inside of the bearing seat. Then, turn on the motor 301, and the output end of the motor 301 can rotate to drive the placement plate 304 to move forward. When the placing plate 304 rotates, the sliding plate 308 can slide outward by centrifugal force. During the movement of the sliding plate 308, the piston rod 313 can be driven to move synchronously by the mounting plate. When the piston rod 313 moves backward, the air inside the piston box 302 can be squeezed, so that the air can be transported to the inside of the fixed box 310 through the air pipe 326. After the air enters the inside of the fixed box 310, it squeezes the push plate 309, so that the push plate 309 can move forward. When the two clamping plates 303 are moved, the control plate can drive the clamping plates 303 to move forward synchronously. After the side surfaces of the two clamping plates 303 are in contact with the surface of the bearing chamber, the top surfaces of the two vertical limiting plates 315 are squeezed, so that the bottoms of the two vertical limiting plates 315 are close to each other. When the two vertical limiting plates 315 are close to each other, the upper and lower positions of the bearing chamber are squeezed, so that the upper and lower positions can be fixed. In addition, the third elastic member 324 can be provided to control the two clamping plates 303 after they are separated from the bearing chamber. The bottoms of the two vertical limiting plates 315 are retracted, and the first airbag 316 can be squeezed through the contact block 317 when the clamping plate 303 is in contact with the bearing chamber. The gas inside the first airbag 316 can enter the second airbag 320 through the connecting tube 319. After the gas enters the second airbag 320, it will expand, so that the surfaces of the two groups of lateral limiting plates 318 can be squeezed and contacted with the surface of the bearing chamber, and the friction block 322 can increase the friction between the lateral limiting plates 318 and the surface of the bearing chamber.
