Description

Technical Field

[0001] This utility model relates to the technical field of multi-station polishing machines, specifically to a multi-station polishing machine for machining motor shafts. Background Technology

[0002] The motor shaft, also known as the rotor shaft, is a crucial rotating component in an electric motor. It is typically made of high-strength metal, with one end firmly connected or press-fitted to the motor's rotor core, and the other end extending outward through the motor's end cover and bearings.

[0003] In the existing technology, the motor shaft is the executor of the motor's energy output. Its quality is directly related to the efficiency, reliability, vibration and noise level and service life of the entire motor system. Most motor shafts have toothed grooves at one end, which can reliably transmit torque and achieve precise circumferential positioning.

[0004] However, after the motor shaft is manufactured, it needs to be polished to prevent burrs from remaining on its surface and affecting its operation. Polishing the motor shaft body and tooth grooves requires two different devices. The motor shaft needs to be placed in two different polishing devices for polishing, which is time-consuming and laborious and affects the improvement of efficiency.

[0005] Based on this, this utility model designs a multi-station polishing machine for motor shaft processing to solve the above problems. Utility Model Content

[0010] Furthermore, the second clamping assembly includes a second clamping bracket, a second rotating block, a spur gear, a fan blade, a toothed block, a rotating rod, and a mounting plate.

[0011] Furthermore, the outer surface of the second rotating block is provided with a straight tooth groove, which is meshed with a spur gear, and the spur gear is meshed with a tooth block.

[0012] Furthermore, the diameter of the straight tooth groove is larger than the diameter of the spur gear, and the diameter of the spur gear is larger than the diameter of the tooth block.

[0013] Furthermore, the motor shaft clamping drive assembly includes a positioning slide rail, a transmission plate, connecting columns, a first motor, a drive plate, and a support ring. The positioning slide rail is fixedly mounted on the upper surface of the base and has two sets symmetrically distributed. The first motor is fixedly mounted inside the base. The lower middle surface of the drive plate is fixedly connected to the output end of the first motor. The two sets of connecting columns are rotatably mounted on the inner walls of both ends of the drive plate. One end of each set of transmission plates is rotatably mounted on the outer surface of the lower end of each set of connecting columns. The other end of each set of transmission plates is rotatably connected to the lower upper surface of the first clamping bracket and the second clamping bracket.

[0014] Furthermore, both the bottom surfaces of the first clamping bracket and the second clamping bracket are provided with sliding grooves, and the inner wall of the sliding groove is in sliding connection with the outer surface of the positioning slide rail.

[0015] Furthermore, a cylinder and multiple sets of guide rods are fixed to the upper side surface of the base. The multiple sets of guide rods are symmetrically distributed.

[0016] Furthermore, the shaft polishing machine or tooth groove polishing machine is fixedly mounted on the surface of the mounting bracket.

The output end of the third motor is fixed with a screw. The other end of the screw is rotatably connected to the lifting base. The screw is threadedly connected to the threaded hole.

[0017] Compared with the prior art, the advantages of this utility model are as follows: 1. When the motor shaft needs to be polished, the motor shaft is first placed on the support ring. According to the principle of two points in a line, the axis of the motor shaft, the first rotating block, and the second rotating block are aligned. The first motor is started to drive the drive plate to rotate slowly. The rotation of the drive plate will reduce the distance between the two ends of the drive plate and the first clamping bracket and the second clamping bracket. Therefore, the rotation of the drive plate will pull the first clamping bracket and the second clamping bracket to move towards each other through the two sets of transmission plates. The gradually moving first clamping bracket and the second clamping bracket will hold one end of the motor shaft body with the first rotating block, and the end of the second rotating block will hold the toothed end of the motor shaft. At this time, under the clamping of both ends, the motor shaft is fixed above the base. 2. Start the second motor to drive the transmission gear to rotate slowly. The slow rotation of the transmission gear will drive the first rotating block to rotate slowly. The slow rotation of the first rotating block will drive the motor shaft to rotate slowly. Then start the shaft polishing machine to polish the smooth surface of the motor shaft at high speed. The slowly rotating first rotating block will make every part of the smooth surface of the motor shaft come into contact with the shaft polishing machine. 3. Start the tooth groove polishing machine to polish the inner wall of the tooth groove of the motor shaft. The slow rotation of the motor shaft will drive the second rotating block to rotate slowly. The second rotating block drives the spur gear to rotate through the meshing of the straight tooth groove and the spur gear. The rotation of the spur gear will drive the rotating rod to rotate, and the rotation of the rotating rod will drive the fan blade to rotate. The rotating fan blade will create airflow, preventing the polishing debris from remaining on the inner wall of the motor shaft tooth groove, thus affecting the polishing effect of the tooth groove polishing machine. Moreover, the diameter of the straight tooth groove is much larger than the diameter of the spur gear, so the rotation speed of the spur gear is much greater than that of the straight tooth groove. The diameter of the spur gear is much larger than the diameter of the tooth block, so the rotation speed of the fan blade is much greater than that of the spur gear. Therefore, the slow rotation of the second rotating block will drive the fan blade to rotate at a high speed, thereby creating airflow. In this structure, the multi-gear transmission is set on both sides of the motor shaft. When polishing the motor shaft, the debris will not affect the gear transmission effect. In actual use, protective treatment can be applied to the outer surface of the first and second rotating blocks. Attached Figure Description

[0028] The motor shaft clamping drive assembly 4 includes a positioning slide rail 6, a transmission plate 7, a connecting column 8, a first motor 9, a drive plate 24, and a support ring 26. The positioning slide rail 6 is fixedly mounted on the upper surface of the base 1 and has two sets symmetrically distributed. The first motor 9 is fixedly mounted inside the base 1. The lower middle surface of the drive plate 24 is fixedly connected to the output end of the first motor 9. The two sets of connecting columns 8 are rotatably mounted on the inner walls of both ends of the drive plate 24. One end of each set of transmission plates 7 is rotatably mounted on the outer surface of the lower end of each set of connecting columns 8.

[0030] A cylinder 30 and multiple sets of guide rods 32 are fixed on the upper side surface of the base 1. The multiple sets of guide rods 32 are symmetrically distributed. A lifting base 33 is fixedly connected to the output end of the cylinder 30. The lifting base 33 is slidably connected to the guide rods 32. A mounting bracket 27 is slidably provided on the upper surface of the lifting base 33.

[0031] The shaft polishing machine 2 or the tooth groove polishing machine 3 is fixedly mounted on the surface of the mounting bracket 27. The side surface of the mounting bracket 27 is provided with a threaded hole 28. The side surface of the lifting base 33 is fixedly provided with a third motor 29. The output end of the third motor 29 is fixed with a screw 31. The other end of the screw 31 is rotatably connected to the lifting base 33. The screw 31 is threadedly connected to the threaded hole 28. The cylinder 30 can drive the lifting base 33 to rise or fall and limit it through the guide rod 32. Therefore, the height of the polishing machine can be adjusted to facilitate polishing. Then, the third motor 29 can drive the mounting bracket 27 to move left and right through the connection between the screw 31 and the threaded hole 28, so that the polishing machine can polish the entire surface of the motor shaft 10.

[0032] In actual use, when the motor shaft 10 needs to be polished, the motor shaft 10 is first placed on the support ring 26. According to the principle of two points in a line, the axis of the motor shaft 10, the first rotating block 25, and the second rotating block 17 are aligned. The first motor 9 is started to drive the drive plate 24 to rotate slowly. The rotation of the drive plate 24 will reduce the distance between the two ends of the drive plate 24 and the first clamping bracket 11 and the second clamping bracket 12. Therefore, the rotation of the drive plate 24 will simultaneously pull the first clamping bracket 11 and the second clamping bracket 12 to move towards each other through the two sets of transmission plates 7. The gradually moving first clamping bracket 11 and the second clamping bracket 12 will push the first rotating block 25 against one end of the motor shaft 10, and the end of the second rotating block 17 will push against the toothed end of the motor shaft 10. At this time, under the clamping of both ends, the motor shaft 10 is fixed above the base 1. The second motor 15 is started, which drives the transmission gear 14 to rotate slowly. The slow rotation of the transmission gear 14 will drive the first rotating block 25 to rotate slowly. The slow rotation of the first rotating block 25 will drive the motor shaft 10 to rotate slowly. Then the shaft polishing machine 2 is started to polish the smooth shaft surface of the motor shaft 10 at high speed. The slowly rotating first rotating block 25 will make every part of the smooth shaft surface of the motor shaft 10 come into contact with the shaft polishing machine 2. The tooth polishing machine 3 is started to polish the inner wall of the tooth groove of the motor shaft 10. The slow rotation of the motor shaft 10 will drive the second rotating block 17 to rotate slowly. The second rotating block 17 drives the spur gear 19 to rotate through the meshing of the straight tooth groove 18 and the spur gear 19. The rotation of the spur gear 19 will drive the rotating rod 22 to rotate, and the rotation of the rotating rod 22 will drive the fan blade 20 to rotate. The rotating fan blade 20 will generate airflow to prevent the polishing debris from remaining on the inner wall of the tooth groove of the motor shaft 10, thus affecting the polishing effect of the tooth polishing machine 3. Moreover, the diameter of the straight tooth groove 18 is much larger than that of the spur gear 19. Because the diameter of the spur gear 19 is much larger than that of the spur tooth 18, and the diameter of the spur gear 19 is much larger than that of the tooth block 21, the rotation speed of the fan blade 20 is much larger than that of the spur gear 19. Therefore, the slow rotation of the second rotating block 17 will drive the fan blade 20 to rotate at a high speed, thereby forming an airflow. The multi-gear transmission in this structure is set on both sides of the motor shaft 10. When polishing the motor shaft 10, the debris will not affect the gear transmission effect. In actual use, the outer surfaces of the first rotating block 25 and the second rotating block 17 can be protected. This structure can polish both the motor shaft 10 and the tooth groove simultaneously, enabling multi-station polishing, which reduces polishing time and improves polishing efficiency.

[0033] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
