Description

Technical Field

[0001] This invention relates to the field of carbon brush polishing technology, specifically to a carbon brush precision polishing device. Background Technology

[0002] Large synchronous motors are core power equipment in the industrial field, and large water conservancy pumping stations are also one of their main application areas. They have high power factor, good operating stability, low sensitivity to grid voltage fluctuations, and high reliability. Their excitation power supply is connected to the rotor through a carbon brush slip ring device. Before a new carbon brush is put into use, its contact surface needs to be ground according to the size of the slip ring and the installation angle of the carbon brush to ensure that it has a good contact surface during operation.

[0003] Currently, the main grinding method in the industrial field is to use a roller with the same radius as the slip ring, attach sandpaper to its surface to create an arc friction surface, and then use a carbon brush holder to fix the carbon brush perpendicular to its surface. The arc of the carbon brush is ground by rotating the roller. Different sizes of slip rings require the manufacture of rollers of corresponding sizes. Since the slip rings of large synchronous motors are relatively large, the equipment for this grinding method is relatively bulky, the grinding efficiency is relatively low, and the applicability is relatively poor.

Through the clamping seat 501, clamping sliders 502, clamping block 503, third threaded cylinder 504, third bidirectional threaded rod 505, handwheel 506, and slag discharge port 507, the clamping block 503 can be opened and closed by rotating the third bidirectional threaded rod 505 during use, thereby fixing the carbon brush.

[0034] Working principle: When in use, place the carbon brush between the two clamping blocks 503, and then turn the handwheel 506. The handwheel 506 drives the third bidirectional threaded rod 505 to rotate. When the third bidirectional threaded rod 505 rotates, it pushes the two third threaded cylinders 504 to move towards the middle, thereby driving the clamping slider 502 to slide towards the middle, so that the two clamping blocks 503 move towards the middle to clamp and fix the carbon brush. Then, the torsion bar 404 is twisted, which drives the active bevel gear 406 to rotate. The active bevel gear 406 drives the driven bevel gear 407 to rotate the lifting screw 405. When the lifting screw 405 rotates, it pushes the lifting block 402 to adjust the height of the lifting top plate 403, thereby adjusting the height of the carbon brush so that the line connecting the center point of the carbon brush and the center of the rotating shaft 103 is parallel to the upper surface of the panel 201. Then slide the transverse seat 301 to move the carbon brush to the grinding position below the grinding wheel head 107. Then twist the second bidirectional threaded rod 309. The second bidirectional threaded rod 309 pushes the two second threaded cylinders 306 to make the two extrusion blocks 305 slide outward. When the extrusion blocks 305 slide outward, they push the pressure inclined surface through the extrusion inclined surface to make the lifting conversion block 303 and the meshing tooth block 304 descend until the meshing tooth block 304 engages and locks with the rack 203. Then, slide the arc diameter adjustment slider 105. The arc diameter adjustment slider 105 drives the grinding motor 106 and the grinding wheel head 107 to move through the motor connecting piece 120. By comparing with the scale 114, the vertical tangent line of the grinding wheel head 107 near the carbon brush is aligned with the corresponding scale value of the scale 114, thereby adjusting the grinding arc of the grinding wheel head 107. Then, twist the first bidirectional threaded rod 119. The first bidirectional threaded rod 119 pushes the two first threaded cylinders 118 to move outward, thereby driving the two locking pressure blocks 116 and the anti-sliding block 117 to move outward, so that the anti-sliding block 117 squeezes the inner slide groove 112 to form a positioning. Then start the vacuum pump 210, the vacuum pump 210 draws in air, so that the airflow passes through the outer grid 204 and enters the powder chamber 207, then enters the waste box 211, and then the airflow passes through the dust filter 212 and the inner grid 209 and enters the negative pressure chamber 208, and finally passes through the vacuum pump 210 and is discharged. Then, the grinding motor 106 is started, which drives the grinding wheel head 107 to rotate. Then, the electric push rod 104 is started. The electric push rod 104 rises and falls slowly in a periodic manner. When the electric push rod 104 rises and falls, it will drive the slide rod 101 to swing up and down, thereby driving the grinding wheel head 107 to form a revolution arc, thus grinding the carbon brush on the side into the corresponding arc size. Meanwhile, a lot of powder is generated during carbon brush polishing. This powder is drawn into the waste box 211 by the airflow through the outer grid 204 and then intercepted by the dust filter 212, thereby avoiding the generation of large amounts of flying dust.
