Description

Technical Field

[0001] This utility model relates to the field of motor rotor processing technology, and in particular to a motor rotor polishing machine. Background Technology

[0002] The motor rotor is the rotating part of the motor. The motor consists of two parts: the rotor and the stator. It is a device used to convert electrical energy into mechanical energy and mechanical energy into electrical energy. During the grinding process, the rotor will generate a lot of debris. If the particle size of the debris is in the particle size range, the mass of the debris is relatively large and is dominated by gravity, so it may be missed when the fan is collecting dust.

[0003] Chinese Patent No. CN222371298U discloses a motor rotor polishing device, including a base and a clamping assembly mounted on the upper surface of the base. The clamping assembly includes a polishing box fixed above the base, and the polishing box has a groove inside. This application uses a clamping assembly to clamp and flip the rotor, avoiding the need for workers to repeatedly flip the rotor and clamp it, effectively reducing the labor intensity of workers and greatly improving the efficiency of polishing. The cleaning component effectively absorbs the iron filings generated during the polishing process, preventing the iron filings from harming the workers.

[0004] However, the above solution has the following shortcomings: during the grinding process, the device clamps the rotor mainly by adjusting the distance between the two clamping plates through gear meshing. Gear meshing is generally lubricated with lubricating oil, and the grinding debris will fall onto the lubricating oil, thereby increasing the wear rate of the gears. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a motor rotor polishing machine that reduces the maintenance frequency of the polishing machine by setting corresponding protective measures on the transmission structure of the clamping component and the polishing component, and setting corresponding baffles and water pipes at the polishing component, so that the liquid and baffles restrict the movement direction of the debris.

[0006] The present invention provides a motor rotor polishing machine, comprising: a base plate with a polishing box at its top; a clamping assembly disposed on the polishing box; and a polishing mechanism comprising a polishing assembly disposed on the polishing box, a fixing ring disposed on the polishing assembly, a mounting ring detachably disposed on the fixing ring, a water inlet pipe disposed at the top of the mounting ring, a water passage pipe disposed at the bottom of the mounting ring, a plurality of spray pipes connected in a ring along the water passage pipe, and a baffle plate disposed on the mounting ring.

[0007] Preferably, the polishing assembly includes a motor a mounted on a polishing box, a lead screw mounted on the motor a, a movable block threaded onto the lead screw, multiple bellows mounted on both sides of the movable block, a telescopic rod mounted below the movable block, a motor c mounted at the output end of the telescopic rod, and a polishing wheel mounted at the output end of the motor c.

[0008] Preferably, the polishing box is equipped with a dust collection rack, on which a filter cartridge is placed, and the dust collection rack is connected to a cleaning component.

[0009] Preferably, the clamping assembly includes a hydraulic cylinder mounted on the polishing box, a lifting frame mounted on the output end of the hydraulic cylinder, two connecting rods rotatably mounted on the lifting frame, a guide frame mounted on the polishing box, two adjusting blocks slidably mounted on the guide frame and rotatably connected to the connecting rods, an extension rod mounted on each of the two adjusting blocks, and a clamping column rotatably mounted on each of the two extension rods.

[0010] Preferably, multiple rotating rollers are rotatably mounted on both adjusting blocks.

[0011] Preferably, ribs are provided at both the upper and lower ends of the two extension rods, and buffer pads are provided on both ribs.

[0012] Preferably, the polishing box is also provided with a Roman rod, and multiple shielding cloths are provided on the polishing box and the extension rod, with the multiple shielding cloths sliding in contact with the Roman rod.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects: In use, the rotor with its end faces facing left and right is fixed to the clamping assembly. The clamping assembly rotates, while the polishing assembly moves to polish the polishing points of the rotor. If the stepped points of the rotor need to be polished, the baffles on the mounting ring are distributed at the front, back and top of the rotor to block the metal shavings produced by polishing, preventing them from splashing onto other structures and reducing the frequency of machine maintenance. At the same time, the water pipe on the mounting ring sprays liquid towards the rotor through multiple evenly distributed spray pipes. The liquid carries the metal shavings downwards, thereby reducing the amount of metal shavings floating in the air. Attached Figure Description

[0015] Example 1, as Figures 1-4 As shown, this embodiment proposes a motor rotor polishing machine, including a base plate 1, a clamping assembly 4, and a polishing mechanism. A polishing box 2 is provided at the top of the base plate 1. The transmission structure of the clamping assembly 4 is located on the outside of the polishing box 2, and the clamping assembly 4 extends from the outside of the polishing box 2 into the interior of the polishing box 2 to clamp the rotor. The polishing mechanism includes a polishing assembly provided on the polishing box 2, a fixing ring 12 provided on the polishing assembly, a mounting ring 14 detachably provided on the fixing ring 12, a water inlet pipe 17 provided at the top of the mounting ring 14, a water passage pipe 16 provided at the bottom of the mounting ring 14, multiple spray pipes 18 connected in a ring along the water passage pipe 16, and a baffle plate 15 provided on the mounting ring 14. The fixing ring 12 has multiple arc-shaped through grooves distributed in a ring, so that the mounting ring 14 can be fixed to the fixing ring 12 through the multiple arc-shaped through grooves and bolts and nuts, and the angle can be adjusted according to the shape of the rotor to improve the practicality of the mounting ring 14. A water pump is connected to the water inlet pipe 17, so that the water pump drives the liquid to flow towards the water passage pipe 16.

[0016] In this embodiment, the rotor with its end faces facing left and right is fixed to the clamping assembly 4. The clamping assembly 4 rotates, and the polishing assembly moves simultaneously, allowing the polishing assembly to grind the polishing points of the rotor. If the stepped points of the rotor need to be polished, the baffles 15 provided on the mounting ring 14 are distributed at the front, back and top of the rotation, thereby blocking the metal debris produced by the polishing and preventing it from splashing onto other structures, thus reducing the maintenance frequency of the machine. At the same time, the water pipe 16 provided on the mounting ring 14 sprays liquid towards the rotor through multiple evenly distributed spray pipes 18. The liquid carries the metal debris downwards, thereby reducing the metal debris floating in the air. If the stepped points of the rotor do not need to be polished and the stepped points are far from the polishing points, the baffles 15 can be set in a ring shape, thereby increasing the shielding range of the baffles 15 and further preventing metal debris from moving onto other structures and causing damage.

[0017] Example 2, as Figures 1-3As shown, this embodiment of the motor rotor polishing machine, compared to Embodiment 1, includes a polishing assembly comprising a motor a5 mounted on a polishing box 2, a lead screw 6 mounted on the motor a5, a moving block 8 threadedly connected to the lead screw 6, multiple bellows 7 on each side of the moving block 8, a telescopic rod positioned below the moving block 8, a motor c9 positioned at the output end of the telescopic rod, and a polishing wheel 13 positioned at the output end of the motor c9. The motor a5 reverses the lead screw 6, causing the moving block 8 to reciprocate on the lead screw 6. Simultaneously, according to the distribution of the polishing points, the telescopic rod drives the motor c9 to rise and fall, thereby allowing the polishing wheel 13 to move back and forth. 3. It is always in contact with the polishing point. At the same time, the telescopic rod is a screw-type electric telescopic rod. Screw-type electric telescopic rods generally have the function of telescopic length control, so it is a known technology and will not be described in detail. The polishing box 2 is equipped with a dust collection frame 10 with the dust collection direction facing upward. A filter cartridge 11 is placed on the dust collection frame 10. When metal debris passes through the filter cartridge 11, some of the metal debris will be filtered by the filter cartridge 11, which makes it easier for workers to clean the metal debris later. The dust collection frame 10 is connected to the cleaning component 3. The relevant structure of the cleaning component 3 is consistent with the setting structure of the cleaning component in the referenced document CN222371298U, so it will not be described in detail.

[0018] Example 3, as Figure 1 and Figure 2 As shown, this embodiment of the motor rotor polishing machine, compared to Embodiment 1, includes a clamping assembly 4 comprising a hydraulic cylinder 41 mounted on the top of the polishing box 2, a lifting frame 42 mounted on the output end of the hydraulic cylinder 41, two connecting rods 43 rotatably mounted on the lifting frame 42, a guide frame 44 mounted on the polishing box 2, two adjusting blocks 45 slidably mounted on the guide frame 44 and rotatably connected to the connecting rods 43, an extension rod 47 mounted on each of the two adjusting blocks 45, and a clamping column rotatably mounted on each of the two extension rods 47. The conveyor belt of the hydraulic cylinder 41 drives the lifting frame 42 to rise and fall, and during the rising and falling process of the lifting frame 42, a clamping column is pulled... The moving or pressing linkage 43 moves and rotates. Under force, the two linkages 43 drive the two adjusting blocks 45 to move, thereby allowing the two adjusting blocks 45 to adjust the distance between them according to the clamping needs. The extension rods 47 set on the two adjusting blocks 45 extend into the polishing box 2, so that the transmission structure of the clamping assembly is distributed on the outside of the polishing box 2, reducing the probability that debris will pass through the polishing box 2 and move to the transmission structure and affect it. At the same time, in order to allow the rotor to be in a rotating state during polishing, a motor b48 is set on one of the extension rods 47. The motor b48 is connected to its corresponding clamping column, so that the clamping column drives the rotor to rotate through friction transmission.

[0019] Example 4, as Figure 1 and Figure 2As shown in this embodiment, compared to Embodiment 1, this embodiment proposes a motor rotor polishing machine. In this embodiment, ribs are provided at both the upper and lower ends of the two extension rods 47, and buffer pads are provided on both ribs. During the rotor processing, the extension rods 47 extend into the polishing box 2. When the extension rods 47 are subjected to the force applied by the polishing wheel 13 and the rotor's own weight, the extension rods 47 tend to tilt downwards. The ribs and buffer pads can support the extension rods 47. At the same time, the buffer pads can reduce the wear of the ribs during use. The external force received by the extension rods 47 will gradually move towards the ribs, buffer pads and polishing box 2. The buffer pads can absorb a certain force, thereby reducing the impact of external forces on the polishing box 2.

[0020] The polishing box 2 is also equipped with a Roman rod. Multiple shielding cloths are provided on the polishing box 2 and the extension rod 47. The shielding cloths slide in contact with the Roman rod and are located on both sides of the extension rod. As the extension rod 47 moves, it pulls the shielding cloths to block the gap between the polishing box 2 and the extension rod 47, thereby reducing the probability of debris passing through the gap.

[0021] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
