[0035] See also Figure 1 , combined with Figure 2-6 An embodiment of the present invention provides a polishing device for parts of a generator set, comprising a cleaning component 1, a clamping component 2, a power component 3, a polishing disc 4 and an adjustment component 5.

[0036] The cleaning component 1 is installed at the bottom of the power component 3, and is used to uniformly recycle metal debris generated when polishing parts to prevent the metal debris from floating in the air.

[0037] The clamping assembly 2 is installed on one side of the top of the power assembly 3, and the clamping assembly 2 is used to clamp and fix the parts that need to be polished.

[0038] The power assembly 3 is installed on the top of the cleaning assembly 1, and the power assembly 3 is used to provide power for the circular rotation of the polishing part.

[0039] The adjusting assembly 5 is installed on one side of the top of the power assembly 3 , and the adjusting assembly 5 is used to adjust the position of the polishing disc 4 to facilitate polishing of different parts.

[0040] The polishing disc 4 is installed on one side of the adjusting assembly 5, and the polishing disc 4 is used to polish the parts of the generator set that need to be polished.

[0041] Specifically, in the present embodiment, the cleaning assembly 1 comprises a recycling box 11 and a fan blade 14, a connecting frame 12 is fixed to the top of the inner wall of the recycling box 11, a first slide groove 13 is opened on one side of the connecting frame 12, a sealing ring 17 is fixed to the inner wall of the first slide groove 13, a filter screen 16 which abuts against one side of the sealing ring 17 is inserted into the inner side of the first slide groove 13, the filter screen 16 prevents the dust sucked into the recycling box 11 from being discharged again, a box cover 19 is hinged on one side of the recycling box 11, a plurality of dust suction pipes 110 are fixed on the top of the limit box 34, the dust suction pipes 110 are connected to one side of the recycling box 11 through a hose, one side of the fan blade 14 is fixed to the output shaft end of the second motor 38, the top of the recycling box 11 is fixed to the bottom of the limit box 34, when a certain amount of metal debris accumulates in the recycling box 11, the box cover 19 connected with bolts is opened to clean the metal debris inside the recycling box 11.

[0042] By adopting the above technical scheme, the parts of the generator set need to be polished before assembly, which improves the qualified rate of the generator set after assembly. At this time, a large amount of metal debris will be generated when the parts are polished. At this time, an output shaft of the second motor 38 drives the fan blade 14 to rotate, so that negative pressure is generated inside the recovery box 11. The negative pressure enters the multiple dust suction pipes 110 through the hose connection. The multiple dust suction pipes 110 are used to suck the metal debris generated during the polishing of the parts into the recovery box 11. At the same time, the air flow generated by the fan blade 14 can cool the second motor 38. At the same time, a filter 16 is movably inserted on one side of the connecting frame 12 to prevent the dust sucked into the recovery box 11 from being discharged again, and to prevent the metal debris during the polishing of the parts from floating in the air of the workshop, thereby improving the air quality inside the workshop and the comfort of the workers at work. When a certain amount of metal debris accumulates in the recovery box 11, the box cover 19 connected by bolts is opened to clean the metal debris inside the recovery box 11, and the filter 16 can be extracted for replacement, which is simple and convenient to operate.

[0043] In order to clamp and fix the parts that need to be polished, the present embodiment sets up a structure for the clamping assembly. Specifically, the clamping assembly 2 includes a first support frame 22 and an electric slip ring 23. One side of the first support frame 22 is rotatably connected to the fixing frame 21 through a bearing. The bottoms of the first support frame 22 and the second support frame 54 are fixed to the top of the limit box 34. One side of the fixing frame 21 is provided with four second slide grooves 210, and the inner side of the second slide groove 210 is slidably connected to a support rod 29. Four support rods 29 are used to clamp and fix the parts and polish them. Workers do not need to manually polish the surface of the parts, which reduces the work intensity of workers and improves their work efficiency.

[0044] In this embodiment, a guide block 26 is fixed to one side of the support rod 29, a third slide groove 211 is provided on one side of the guide block 26, a slider 27 is slidably connected to the inner side of the third slide groove 211, a first motor 24 is fixed to the inner wall of the fixed frame 21, a screw rod 25 is fixed to the output shaft end of the first motor 24, one side of the screw rod 25 is threadedly connected to one side of the slider 27, the screw rod 25 is threadedly connected to one side of the slider 27, when the slider 27 moves toward the first motor 24, the four support rods 29 are close to each other, a connecting shaft 28 is fixed at the axis of one side of the fixed frame 21, the outer side of the connecting shaft 28 is fixed to the inner ring of the electric slip ring 23, the outer ring of the electric slip ring 23 is fixed to one side of the first support frame 22, the output end of the electric slip ring 23 is electrically connected to the input end of the first motor 24, the four support rods 29 slide to different positions inside the second slide groove 210, and parts of different shapes can be clamped and fixed, thereby improving the versatility of the clamping assembly 2.

[0045] Under the setting of the above technical solution, when it is necessary to clamp the parts of the generator set, it is only necessary to turn the plane to be polished toward the side of the polishing disk 4. At this time, the output shaft of the first motor 24 drives the screw rod 25 to rotate. Because the screw rod 25 is threadedly connected to one side of the slider 27, when the slider 27 moves toward the side of the first motor 24, the four support rods 29 are close to each other to clamp the parts to be polished. By sliding the four support rods 29 at different positions inside the second slide groove 210, parts of different shapes can be clamped and fixed, thereby improving the versatility of the clamping assembly 2. At the same time, the power of the first motor 24 is provided using the electric slip ring 23.

[0046] To provide circular rotation power for parts that need to be polished, the present embodiment makes a structural arrangement for the power assembly 3. Specifically, the clamping and fixing power assembly 3 includes a limit box 34 and a second motor 38. The output shaft end of the second motor 38 is fixed with a second conical tooth 39. The second conical tooth 39 is meshed and connected with two first conical teeth 37. The second motor 38 is a double-axle extension asynchronous motor with two output shafts. The bottom of the second motor 38 is fixed to the bottom of the inner wall of the limit box 34. The top of the inner wall of the limit box 34 is fixed with two limit teeth. Block 36, the limit block 36 is rotatably connected to two first rotating shafts 31 through a bearing, one side of the two first rotating shafts 31 is fixed to one side of the first conical tooth 37, a first sprocket 32 ​​is fixed to the side of the first rotating shaft 31 away from the first conical tooth 37, a second sprocket 33 is fixed to one side of the connecting shaft 28, and a third sprocket 35 is fixed to one side of the second rotating shaft 51, the two first sprockets 32 are linked to the second sprocket 33 and the third sprocket 35 through a chain, and power is transmitted by the chain, so that the power transmission of the second motor 38 is more stable.

[0047] By adopting the above technical solution, when the output shaft at the top of the second motor 38 rotates, the second conical teeth 39 are driven to rotate, and at the same time, the two first conical teeth 37 are engaged to rotate. When the first conical teeth 37 rotate, the first rotating shaft 31 is driven to rotate, and the first sprocket 32 ​​on one side of the first rotating shaft 31 is driven to rotate, and the rotation direction of the first sprocket 32 ​​is reverse rotation. The first sprocket 32 ​​causes the second sprocket 33 and the third sprocket 35 to rotate in the opposite direction at the same time through the chain. At this time, the parts clamped and fixed inside the support rod 29 rotate in the opposite direction to the polishing disk 4, increasing the relative speed between the polishing disk 4 and the parts, saving the polishing time of the parts surface, and improving the polishing efficiency of the parts. At the same time, a second motor 38 is used to drive the parts and the polishing disk 4 to rotate in the opposite direction, reducing the number of motors used and reducing the failure rate of the device.

[0048] In order to facilitate the polishing of different parts, the present embodiment is implemented by an adjustment component, and the adjustment component is structurally arranged. Specifically, the adjustment component 5 includes a square slide bar 52 and a second support frame 54. The second support frame 54 is rotatably connected to the second shaft 51 through a bearing. The inner side of the second shaft 51 is provided with a fourth slide groove 53 which is slidably connected to one side of the square slide bar 52. One side of the fourth slide groove 53 is provided with an air hole to facilitate the entry and discharge of internal gas when the square slide bar 52 slides. A plurality of limiting grooves 55 are provided on the top of the square slide bar 52. One side of the polishing disc 4 is fixed to one side of the square slide bar 52. The limiting groove 55 is a groove for adjusting the polishing disc 4 at any position, and cooperates with the limiting rod 56 to be able to So that the polishing disk 4 is in different positions, a limiting frame 510 is fixed on the outside of the second rotating shaft 51, and a fifth sliding groove 59 is opened on the inside of the limiting frame 510. A slide plate 511 is slidably connected to the inside of the fifth sliding groove 59. A limiting rod 56 adapted to the inside of the limiting groove 55 is fixed to the bottom of the slide plate 511. The limiting rod 56 is inserted into the inner side of a corresponding limiting groove 55 to adjust the position of the polishing disk 4. A sliding column 58 is fixed on the top of the slide plate 511. One side of the sliding column 58 is movable through the top of the limiting frame 510. A spring 57 is sleeved on the outside of the sliding column 58. The two ends of the spring 57 respectively abut against the fifth sliding groove 59 and one side of the slide plate 511. The spring 57 is used to provide elastic force for the limiting rod 56 to be inserted into the inner side of the limiting groove 55.

[0049] Under the setting of the above technical scheme, when parts of different shapes are clamped on one side of the support rod 29, it is necessary to adjust the distance between the polishing disk 4 and the parts. It is only necessary to pull the sliding column 58 to one side so that the spring 57 is compressed and the slide plate 511 slides inside the fifth slide groove 59. At this time, the square slide bar 52 is moved to different positions of the fourth slide groove 53 so that the polishing disk 4 on one side is in contact with one side of the part. At this time, the sliding column 58 is released, and under the action of the spring 57, the limiting rod 56 is inserted into the inner side of a corresponding limiting groove 55, locking the square slide bar 52 on one side of the polishing disk 4 on the inner side of the second rotating shaft 51. By adjusting the position of the polishing disk 4, the surfaces of parts of different shapes can be polished. When polishing disks 4 of different shapes need to be used, the polishing disks 4 are easy to replace, which improves the convenience of using the device.

At this time, the output shaft of the first motor 24 drives the screw rod 25 to rotate, so that the slider 27 threadedly connected to the screw rod 25 moves left and right along the output shaft of the first motor 24. When the slider 27 moves to the left, the speed of the slider 27 is 0.1-0.3 cm / s. At this time, one side of the slider 27 slides inside the third slide groove 211, so that the four support rods 29 move closer to the middle.

The polishing method of the generator set parts polishing device comprises the following steps: S1. Part clamping: placing the generator set parts to be polished between the four support rods (29), and the output shaft of the first motor (24) drives the screw rod (25) to rotate, so that the slider (27) threadedly connected to the screw rod (25) moves left and right along the output shaft of the first motor (24). When the slider (27) moves to the left, one side of the slider (27) slides inside the third slide groove (211), so that the four support rods (29) move closer to the middle, and the parts to be polished are clamped and fixed; S2, polishing distance adjustment, according to the shape of different parts, pull the slide column (58) upward to drive the slide plate (511) to slide inside the fifth slide groove (59), at this time, the spring (57) is compressed, so that the limit rod (56) leaves one of the limit grooves (55), and then pull the square slide bar (52), according to the shape of the parts, the polishing disc (4) is pressed against one side of the parts, and then release the slide column (58) so that the limit rod (56) is inserted into the inner side of the limit groove (55), and the polishing disc (4) can be adjusted to different positions according to the shapes of parts; S3, dust removal. When polishing a part, the output shaft end of the second motor (38) drives the second conical teeth (39) and the fan blade (14) to rotate respectively. When the second conical teeth (39) rotate, the fixed frame (21) and the polishing disc (4) are driven to rotate in the opposite direction, thereby improving the polishing effect of the polishing disc (4) on the part. At the same time, the rotation of the fan blade (14) generates negative pressure. Under the action of the dust suction pipe (110), the metal debris generated when the part is polished is uniformly collected in the recovery box (11). The box cover (19) can be opened to clean the metal debris in the recovery box (11).
