The present invention will be described in further detail with reference to the following specific embodiments and the accompanying drawings.
As shown in fig. 2, the invention provides a slotting device for a yaw brake disc of a wind generating set, which is used in cooperation with a slotting electric grinder, and comprises a base 1, wherein the middle end of the base 1 is provided with a transverse slot clamping part 11 for clamping and clamping the base 1 on the brake disc during slotting, the base 1 is provided with a limiting guide rod 2 which extends outwards and obliquely, a limiting adapter assembly 3 is sleeved on the limiting guide rod 2 for fixing the slotting electric grinder, and the limiting adapter assembly 3 slides back and forth along the limiting guide rod 2 during slotting so as to enable the slotting electric grinder to perform linear slotting on the surface of the brake disc. The specific operation is as follows:
when the groove is opened, the base 1 is clamped on the brake disc by the clamping groove part 11, so that the base 1 is kept fixed. The specific clamping and fixing manner can be realized by clamping the two lifting clamping plates 5 oppositely arranged below, and the height of the clamping groove part 11 can be just correspondingly set to the thickness of the brake disc so as to be just clamped and fixed, which all belong to the protection scope of the invention. After the base 1 is clamped and fixed, the slotting electric grinder is fixed on the limiting adapter assembly 3; then start fluting electric grinder to promote spacing adapter subassembly 3 and slide back and forth, make fluting electric grinder also follow spacing guide arm 2 spacing slip back and forth and keep making a round trip the straight line slip in order to carry out the splendid straight line fluting of effect on the brake disc surface, make the straight line in groove keep the precision high. Because the limiting guide rod 2 extends outwards in an inclined mode, the inclined angle of the limiting guide rod 2 can be accurately set in advance, so that the inclined angle of the limiting guide rod is just 45 degrees relative to the friction direction of the friction plate, the grooving electric grinder which linearly slides along the front and the back of the limiting guide rod 2 can also open a groove which is 45 degrees relative to the friction direction of the friction plate, and the inclined angle precision of the groove is high.

The design of the stop collar 211 allows for convenient and flexible adjustment.
Further, in the preferred embodiment, the base 1 is provided with an angle adjusting plate 4 capable of being adjusted toward the slot portion 11 in a telescopic manner on both side surfaces at the bottom end of the slot portion 11, and the angle adjusting plate 4 abuts against the circumferential surface of the brake disc when the base 1 is clamped and clamped on the brake disc, so as to adjust the slotting angle of the slotting electric grinder by adjusting the clamping depth of the base 1. In this embodiment, the angle adjustment plate 4 is provided with a horizontal movable slot, and more than one tightening screw 41 fixed on the base 1 is inserted into the movable slot for adjusting the extension length of the angle adjustment plate 4. When the adjustment is needed, the tightening screw 41 is loosened, the angle adjusting plate 4 is pushed to a proper position, and then the tightening screw 41 is tightened, so that the angle adjusting plate 4 is fixed. Due to the difference in the diameter of the brake disk from one predetermined diameter to another, the angle of contact with the circumferential surface of the brake disk may change when the base 1 is fixed in the locked state, i.e., the angle may vary. Through the spacing length of adjusting the difference of two angle adjusting plates 4 around, can further realize the slant angle of the spacing guide arm 2 of adjustment of high accuracy for its inclination guarantees to be just in time for being 45 degrees angles with friction disc friction direction, has further guaranteed that fluting electric grinder is enough to open out and is 45 degrees grooves of angle with friction disc friction direction, and then has effectively guaranteed that the slant angle precision in groove is high, also makes this device suitability strong.
Further, in the preferred embodiment, two up-down lifting clamping plates 5 are oppositely arranged in the slot portion 11 for clamping the brake disc, and the two lifting clamping plates 5 are respectively fixed on the top plate and the bottom plate of the base 1 through a plurality of lifting adjusting screws 51 for adjusting the clamping thickness and/or the overall height of the base 1 by adjusting the lifting height of the two lifting clamping plates 5. The lifting of the two lifting clamping plates 5 is adjusted by rotating the lifting adjusting screws 51, for example, when the lifting clamping plate 5 above rises upwards, the lifting clamping plate 5 below falls downwards, the clamping thickness between the two lifting clamping plates 5 is widened, the brake discs with different specifications and different thicknesses can be clamped by the device, and the device is wide in application range. When facing to the slotting electric grinder of different specifications, because the slotting blade of the slotting electric grinder probably has size difference, at this moment, through adjusting two blocks of lifting clamping plates 5 to rise simultaneously or fall simultaneously, then can adjust the whole height of this device, and then realized the general purpose of the slotting electric grinder homoenergetic of different specifications, also guaranteed the required precision of fluting degree of depth simultaneously, further made this device accommodation wide, the fluting precision high.
The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above-mentioned embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the invention may be made by those skilled in the art without departing from the principle of the invention.
