[0002] Wind turbine bearings are a special type of bearings, mainly used to connect the yaw, pitch and transmission system steering of wind turbines, and are one of the core components of wind turbines. The structure of wind turbine bearings mainly includes three parts: inner and outer rings, roller components and cages. The bevel processing of wind turbine bearings is a key step in the manufacturing process, which involves the precise processing of specific parts or surfaces of the bearings to meet their specific functional requirements in wind turbines.

[0003] During the inclined surface processing of wind turbine bearings, positioning tooling is required to fix the bearings. The current tooling can only fix the bearings at a certain angle when in use. Since wind turbine bearings need to be processed with different inclined surface slopes according to usage requirements, different tooling needs to be replaced for fixation during processing, which leads to a decrease in processing efficiency. The tooling cannot adapt to the processing needs of different wind turbine bearings. Utility Model Content

[0010] As a preferred technical solution of the utility model, the bottom of the first hydraulic cylinder is hinged to the base through a first connecting frame, and the piston rod of the first hydraulic cylinder is hinged to the mounting plate through a second connecting frame.

[0011] As a preferred technical solution of the utility model, mounting feet are provided on both sides of the base, and the number of the mounting feet is several and symmetrically distributed on both sides of the base.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] See also Figure 1-Figure 4 In this embodiment, a tooling for processing the inclined surface of a wind turbine bearing is provided, including a base 1, a column 2 is arranged on the upper side of the base 1, a mounting plate 4 is hinged on the top of the column 2 through a U-shaped frame 3, a first hydraulic cylinder 6 is hinged between the base 1 and the mounting plate 4 at a position in front of the column 2, a fixture assembly 7 for positioning and fixing a workpiece is arranged on the upper side of the mounting plate 4, and a cooling assembly 8 for cooling the workpiece is arranged on the base 1.

[0024] In the utility model, the wind turbine bearing that needs to be beveled is clamped and fixed by the clamp assembly 7 on the mounting plate 4, and then the angle of the clamp assembly 7 is adjusted by the first hydraulic cylinder 6 between the mounting plate 4 and the base plate 1 according to the slope of the beveled surface that needs to be processed. When the first hydraulic cylinder 6 is extended or retracted, the mounting plate 4 can be rotated on the column 2 through the U-shaped frame 3, so that the angle of the mounting plate 4 can be adjusted, and then the angle of the clamp assembly 7 can be adjusted, so that the wind turbine bearing clamped on the clamp assembly 7 can adapt to the angle of the beveled surface processing and need to perform corresponding angle adjustment, so that the tooling can adapt to the processing needs of different beveled surface angles of the wind turbine bearing. During the processing, the cooling assembly 8 can realize cooling to avoid the wind turbine bearing being damaged due to excessive temperature during the processing.

[0025] Specifically, refer to Figure 1 and Figure 3 The fixture assembly 7 includes a bracket 7 fixed to the upper side of the mounting plate 4, a second hydraulic cylinder 72 is provided on the bracket 71, and a pressure plate 73 is fixedly connected to the piston rod of the second hydraulic cylinder 72 at a position above the mounting plate 4. The bracket 71 is fixed to the mounting plate 4 by fasteners, and the second hydraulic cylinder 72 on the bracket 71 drives the pressure plate 73 to descend, so that the pressure plate 73 and the mounting plate 4 clamp and fix the wind turbine bearing to be processed, thereby keeping the wind turbine bearing stable during processing to avoid shaking and causing processing errors.

[0026] Specifically, refer to Figure 1 , Figure 3 and Figure 4 The pressing plate 73 is detachably mounted on the piston rod of the second hydraulic cylinder 72 through the connecting tube 732, and a rubber pad 731 is fixedly mounted on the lower side of the pressing plate 73. The rubber pad 731 plays an anti-slip role. When the second hydraulic cylinder 72 drives the pressing plate 73 to clamp the wind turbine bearing, the rubber pad 731 can increase the friction between the pressing plate 73 and the wind turbine bearing, thereby preventing the wind turbine bearing from sliding during processing and improving the stability of the wind turbine bearing clamped on the clamp assembly 7.

[0027] Specifically, refer to Figure 1 and Figure 2 The cooling assembly 8 includes a water tank 81 disposed on the base 1, a circulating pump 82 is fixedly installed on the top of the water tank 81, and a connecting pipe 85 is disposed on the circulating pump 82. The cooling assembly 8 also includes a workbench 83, and a water cooling pipe 84 is disposed inside the workbench 83. The circulating pump 82 circulates the cooling water stored in the water tank 81 through the connecting pipe 85 to the water cooling pipe 84 of the workbench 83, and the wind turbine bearing clamped on the workbench 83 is cooled by the water cooling pipe 84. When the inclined surface of the wind turbine bearing is processed, the high heat caused by the processing is quickly cooled, thereby preventing the wind turbine bearing from being damaged due to the high temperature generated by the processing.

[0028] The workbench 83 is fixed on the upper side of the mounting plate 4 and is located below the pressing plate 73, and the water cooling pipe 84 is distributed in a serpentine shape inside the workbench 83. The serpentine-shaped water cooling pipe 84 can be distributed in a large area in the workbench 83, thereby increasing the cooling speed and quickly taking away the heat generated by the bevel processing of the wind turbine bearing during the processing of the wind turbine bearing.

[0029] The bottom of the first hydraulic cylinder 6 is hinged to the base 1 through the first connecting frame 61, and the piston rod of the first hydraulic cylinder 6 is hinged to the mounting plate 4 through the second connecting frame 62. The first connecting frame 61 and the second connecting frame 62 are used to hinge the two ends of the first hydraulic cylinder 6 to the base 1 and the mounting plate 4 respectively, so that the first hydraulic cylinder 6 can be adjusted to match the angle change when it is extended and retracted, and the mounting plate 4 can be rotated on the column 2.

[0030] There are mounting feet 5 on both sides of the base 1. The number of mounting feet 5 is several and they are symmetrically distributed on both sides of the base 1. The base 1 is mounted and fixed by the mounting feet 5 so that it can be fixed in the processing site of the wind power bearing.

[0031] Working principle: When in use, the second hydraulic cylinder 72 on the bracket 71 drives the pressure plate 73 to descend, so that the pressure plate 73 and the workbench 83 clamp and fix the wind turbine bearing to be processed, and the angle of the clamp assembly 7 is adjusted by the first hydraulic cylinder 6 between the mounting plate 4 and the base plate 1 according to the slope of the bevel processing as required. When the first hydraulic cylinder 6 is extended and retracted, the mounting plate 4 can be rotated on the column 2 through the U-shaped frame 3, so that the angle of the mounting plate 4 can be adjusted, and then the angle of the clamp assembly 7 can be adjusted, so that the wind turbine bearing clamped on the clamp assembly 7 can adapt to the angle of the bevel processing and need to be adjusted accordingly. The circulating pump 82 circulates the cooling water stored in the water tank 81 through the connecting pipe 85 and passes it into the water cooling pipe 84 of the workbench 83. The water cooling pipe 84 is used to cool the wind turbine bearing clamped on the workbench 83. When the wind turbine bearing is processed on the bevel, the high heat caused by the processing is quickly cooled, thereby avoiding damage to the wind turbine bearing due to the high temperature generated by the processing.

[0032] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
