[0041] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to further illustrate the present invention.

[0042] First, combine Figure 1 to Figure 4 The wind turbine bearing ultra-precision grinding equipment according to the embodiment of the utility model is described, and its application scenarios are very wide.

[0043] like Figure 1 As shown, the wind power bearing ultra-precision grinding equipment of the embodiment of the utility model comprises a slide module 1, a clamping module 2 and a grinding module 3.

[0044] Specifically, Figure 1 As shown, the clamping module 2 is used to clamp the wind turbine bearing to be ground; the grinding module 3 is slidably arranged on the slide module 1 and arranged adjacent to the clamping module 2 , and the grinding module 3 grinds the wind turbine bearing on the clamping module 2 .

[0045] Further, if Figure 1 As shown, the slide module 1 includes: a slide rail 11, a slide 12 and a driving mechanism 13; the slide 12 is slidably arranged on the slide rail 11, and the slide 12 is connected to the grinding module 3, and the slide 12 drives the grinding module 3 to move along the slide rail 11; the driving mechanism 13 is connected to the slide 12, and the driving mechanism 13 drives the slide 12 to move. In this embodiment, a plurality of slides 12 can be arranged on the slide rail 11, and each slide 12 is provided with a grinding module 3. When multiple grinding modules 3 are grinding at the same time, the grinding efficiency can be improved.

[0046] Further, if Figure 1 As shown, the clamping module 2 includes: a base 21, a magnetic chuck 22 and a pick-and-place mechanism 23; the magnetic chuck 22 is arranged on the base 21, and is used to place the wind turbine bearing to be ground. When the magnetic chuck 22 is powered, it generates a strong magnetic attraction, which can firmly fix the bearing; the pick-and-place mechanism 23 is connected to the magnetic chuck 22, and is used to clamp the wind turbine bearing on the magnetic chuck 22. In this embodiment, the pick-and-place mechanism 23 is preferably a mechanical arm, and the mechanical arm is controlled by an external program to pick up and place the wind turbine bearing.

[0047] Further, if Figure 2 As shown, the grinding module 3 includes: a connecting member 31, an oilstone unit 32 and an oscillation unit 33; the oilstone unit 32 is used to grind wind power bearings, and the oilstone unit 32 is connected to one end of the connecting member 31; the oscillation unit 33 is used to generate oscillations, and the oscillation unit 33 is connected to the other end of the connecting member 31, and the oscillation unit 33 drives the oilstone unit 32 to reciprocate through the connecting member 31. The oilstone unit 32, the oscillation unit 33 and the connecting member 31 of the grinding module 3 in this embodiment are not integrated, but are connected together by bolts and nuts. No matter which part needs to be replaced during the grinding process, it is very convenient. For the scenario where only the oilstone unit 32 needs to be replaced, the oilstone unit 32 in this embodiment can be removed from the connecting member 31, and it is not necessary to replace it together with the oscillation unit 33. Compared with the grinding heads on traditional grinding equipment, which are all integrated and the oscillation unit 33 must be replaced at the same time when it is replaced, the grinding module 3 in this embodiment is more economical and convenient.

[0048] Furthermore, the connecting member 31 is entirely detachable and replaceable. The connecting member 31 in this embodiment can be selected to have different lengths according to the actual bearings to be ground, so as to facilitate the grinding of bearings of various heights.

[0049] Further, if Figure 3 As shown, the oilstone unit 32 includes: a plurality of oilstone seats 321, a pair of oilstone racks 322, a pneumatic component 323 and an oilstone switching component 324; the plurality of oilstone seats 321 are used to install the oilstones required for grinding; an oilstone seat 321 is provided at both ends of each oilstone rack 322; the pneumatic component 323 is connected to the pair of oilstone racks 322, and the pneumatic component 323 is used to drive the oilstone racks 322 to move; the oilstone switching component 324 is connected to the pneumatic component 323, and the oilstone switching component 324 is used to rotate and switch the oilstone rack 322 on the pneumatic component 323.

[0050] Further, if Figure 3 , 4As shown, the pneumatic assembly 323 includes: a pneumatic block 3231, a piston 3232, a piston rod 3233 and a pair of air passages 3234; the pneumatic block 3231 is connected to a pair of oilstone racks 322; a piston cavity 3235 is provided inside the pneumatic block 3231, and a piston rod 3233 is provided in the piston cavity 3235; the piston 3232 is sleeved on the piston rod 3233 and fixed to the middle section of the piston rod 3233, and the piston 3232 divides the piston cavity 3235 into two chambers; a sealing member 3234 is movably sleeved on both ends of the piston rod 3233 236, used for sealing each chamber. When gas is introduced into any chamber, since the piston 3232 is fixed, the seal 3236 used to seal the chamber will move along the piston rod 3233 as the air pressure in the chamber increases. The movement of the seal 3236 will move the pneumatic block 3231 together. A pair of air passages 3234, a pair of air passages 3234 are respectively opened inside the piston rod 3233 located in the two chambers, each air passage 3234 is connected to a chamber, and the external gas flows into the corresponding chamber through the air passage 3234.

The guide posts 3237 are used to guide the movement of the pneumatic block 3231.

[0051] When grinding a bearing, in order to ensure the grinding effect, the pressure of the oilstone on the grinding surface of the bearing needs to remain constant. At this time, it is necessary to transport the gas into the chamber through the air channel 3234 through an external air source. As the air pressure in the chamber increases, a thrust will be generated on the seal 3236, and the seal 3236 will drive the pneumatic part to move along the piston rod 3233. The pneumatic part will drive the oilstone rack 322 while moving, and the oilstone on the oilstone seat 321 on the oilstone rack 322 will also move. In this way, the oilstone is pressurized. When the air pressure in the chamber is constant, the pressure generated is also constant, so that the pressure of the oilstone on the grinding surface of the bearing will be constant, which ensures the grinding effect and improves the grinding accuracy.

[0052] Further, if Figure 3As shown, the oilstone switching assembly 324 includes: a worm gear mechanism (not shown in the figure) and a power element 3241; the worm gear mechanism is connected to the pneumatic block 3231; the output end of the power element 3241 is connected to the worm gear mechanism, the power element 3241 drives the worm gear mechanism to move, and the worm gear mechanism drives the pneumatic block 3231 to rotate.

[0053] Furthermore, the oilstone unit 32 further comprises: a stock detection device (not shown in the figure), which is arranged adjacent to the oilstone seat 321 and is used to detect the stock of the oilstone on the oilstone seat 321 .

[0054] When in use, the wind turbine bearing to be ground is placed on the magnetic chuck 22 by the mechanical arm, and the magnetic chuck 22 sucks the wind turbine bearing tightly, and then the oscillation unit 33 vibrates, and the oilstone unit 32 is driven to vibrate together through the connecting piece 31 to achieve the grinding of the wind turbine bearing. After the grinding is completed, the wind turbine bearing is removed by the mechanical arm.
