Description

[0001] This invention belongs to the field of motor manufacturing technology, specifically relating to a bearing heating device for permanent magnet synchronous motor manufacturing. Background Technology

[0002] Permanent magnet synchronous motors consist of components such as stator, rotor, and end covers. They are powered by permanent magnets, which simplifies the motor structure, reduces processing and assembly costs, and eliminates the slip rings and brushes that are prone to problems, thus improving the reliability of motor operation. Furthermore, since no excitation current is required, there is no excitation loss, which improves the efficiency and power density of the motor. They have the advantages of small size, simple structure, and high power density.

[0003] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical bodies, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. Bearing heaters are needed for heating during the bearing manufacturing process.

[0004] Existing bearing heating equipment mostly adopts a single-sided heating method. During the heating process, heat is conducted from one side of the bearing to the other. Due to the limited thermal conductivity of the bearing material, the part far from the heat source is difficult to reach the same temperature as the contact surface of the heat source in a short time. This results in obvious temperature differences in different parts of the bearing after heating, poor heating uniformity, and uneven heating will affect the performance of the bearing.

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] like Figures 1 to 9 As shown, the present invention provides a technical solution: a heating device for bearings in the production of permanent magnet synchronous motors, including a worktable 1, an inclined platform 2 fixedly installed above the worktable 1, an inclined platform 3 arranged on one side below the inclined platform 2, a heat source plate 4 and a heat source plate 5 respectively fixedly installed on the inner walls of the inclined platform 2 and the inclined platform 3, a clamping and flipping assembly arranged on the surface of the inclined platform 2, the clamping and flipping assembly including two clamping rods 6, the clamping and flipping assembly can flip the bearing surface through the two clamping rods 6, a flaring assembly is arranged at the bottom between the inclined platform 2 and the inclined platform 3 to drive the angle expansion of the two clamping rods 6, a tilting assembly is arranged at the bottom of the inclined platform 3 to drive the inclined platform 3 to increase the tilt angle, and a feeding assembly for automatic feeding is arranged on the upper side of the inclined platform 2.

[0035] During operation: In the initial state, the two clamping rods 6 are V-shaped with their open ends facing upwards. At this time, one of the multiple bearings to be heated placed on the upper side of the inclined platform 2 will automatically slide down the inclined surface of the inclined platform 2 and accurately enter between the two clamping rods 6 until the outer wall of the bearing is in close contact with the inner side of the two clamping rods 6. At this time, the bearing is just steadily above the heat source plate 4, and the heat source plate 4 will start working to heat one side of the bearing. After one side of the bearing is heated, the clamping and flipping assembly is activated and begins to move. The clamping and flipping assembly cleverly controls the movement of the two clamping rods 6 to hold the bearing steadily and perform a flipping operation. After flipping, the bearing is moved to the upper side of the heat source plate 5 at the inclined platform 23. At this time, the side of the bearing that was not heated is adjacent to the upper surface of the heat source plate 25, and the heat source plate 25 starts working to heat the other side of the bearing.

[0036] After both sides of the bearing are heated, the entire clamping assembly, along with the bearing, is positioned above the tilting platform 2 3. At this time, the open ends of the two clamping rods 6 face downwards, and the flaring assembly begins to move. It forcibly opens the two clamping rods 6, causing the angle between them to increase continuously, thereby losing the clamping force on the bearing. At this time, the bearing will temporarily remain on the upper surface of the heat source plate 2 5. Although the tilting platform 2 3 and the heat source plate 2 5 maintain a certain tilt in the initial state, due to the static friction between the bearing and the tilting platform 2 3 and the heat source plate 2 5, the bearing may not be able to slide smoothly down the slope of the heat source plate 2 5 and the tilting platform 2 3 by its own weight alone.

[0037] When the flaring assembly continues to move after expanding the two clamping rods 6, it will trigger the tilting assembly to start working. The tilting assembly can further increase the tilt angle of the tilting platform 2 3. As the tilt angle of the tilting platform 2 3 gradually increases, the component of the gravity on the bearing along the inclined plane will also continuously increase. When this component force increases to a level sufficient to overcome the friction between the bearing and the tilting platform 2 3 and the heat source plate 2 5, the bearing will automatically slide smoothly down the inclined plane of the tilting platform 2 3 at a certain moment.

[0038] After the heating process of the first bearing is completed, the clamping and tilting assembly rotates in the opposite direction and precisely resets to the initial state. Then, the feeding assembly automatically starts to replenish the material. The feeding assembly has a precise control mechanism that will only allow one bearing to fall onto the inclined surface of the tilting table 2, and will apply an appropriate thrust to the bearing in time to ensure that the bearing can slide smoothly down the inclined surface of the tilting table 2, avoiding jamming, accumulation and other situations that affect the normal operation of the equipment.

[0039] Through the above embodiments, in the initial state, the two clamping rods 6 are V-shaped with their open ends facing obliquely upwards, guiding the bearing to automatically slide down between the two rods and make close contact, so that the bearing accurately stops above the heat source plate 4. After one side of the bearing is heated, the clamping and flipping assembly controls the movement of the two clamping rods 6 to firmly clamp the bearing and flip it, moving the bearing to the top of the heat source plate 5 at the tilting platform 3, so that the originally unheated side is adjacent to the upper surface of the heat source plate 5, realizing the heating requirements of both sides of the bearing, thereby enabling the bearing to be fully and evenly heated during the heating process, improving heating quality and efficiency; through the flaring assembly, the two clamping rods 6 are forcibly opened, so that the angle between them continuously increases, thereby releasing the clamping force on the bearing, making the shaft... The system creates conditions for the bearing to slip off, allowing it to break free from the clamping rod 6 and rest on the upper surface of the second heat source plate 5. The tilting assembly further increases the tilt angle of the second tilting platform 3, altering the force on the bearing on the second heat source plate 5. The bearing overcomes the friction between itself and the second tilting platform 3 and the second heat source plate 5, smoothly sliding off the inclined surface of the second tilting platform 3, thus achieving automatic bearing discharge. The feeding assembly controls the number of bearings falling, allowing only one bearing to fall onto the inclined surface of the first tilting platform 2, and promptly applies a suitable thrust to the bearing. This prevents multiple bearings from entering simultaneously, avoiding jamming and accumulation, ensuring continuous and stable equipment operation, and improving the reliability and stability of the production process.

[0040] like Figures 2 to 4 As shown, the clamping and tilting assembly includes a rotating component 9, a rotating shaft 8 fixedly connected to the inner wall of the rotating component 9, a motor 7 fixedly connected to the side of the tilting platform 2, the output shaft of the motor 7 fixedly connected to one end of the rotating shaft 8, a fixed seat 10 symmetrically fixedly connected to the top of the tilting platform 2, the outer wall of the rotating shaft 8 rotatably connected to the inner wall of the fixed seat 10, a double-end hinge 11 fixedly connected to one end of the rotating component 9, the inner walls of the two ends of the double-end hinge 11 being hinged to one end of the clamping rod 6 respectively, and a torsion spring 12 fixedly connected between the two clamping rods 6 and the rotating component 9.

[0041] During operation: In the initial state, the two clamping rods 6 are V-shaped with their open ends facing upwards, waiting for the bearing to slide in; when one of the multiple bearings to be heated placed above the side of the inclined platform 2 slides down automatically along the inclined surface of the inclined platform 2 and enters between the two clamping rods 6, until the outer wall of the bearing is in close contact with the inner side of the two clamping rods 6, at this time, the clamping rods 6 are subjected to the outward squeezing force of the bearing, but due to the elastic force of the torsion spring 12, the clamping rods 6 will generate a reverse clamping force on the bearing, clamping the bearing and preparing it for subsequent heating;

[0042] After the bearing has been heated on one side of the heat source plate 4, the motor 7 starts and its output shaft begins to rotate. The rotating shaft 8 drives the rotating part 9 to rotate around the rotating shaft 8. The double-ended hinge 11 connected to one end of the rotating part 9 also rotates, which in turn drives the two clamping rods 6 and the clamped bearing to rotate together. As the rotating part 9 rotates, the bearing is flipped to the top of the heat source plate 5 at the tilting platform 23. At this time, the side of the bearing that was not heated is adjacent to the upper surface of the heat source plate 25, and the heat source plate 25 can start to heat the other side of the bearing.

[0043] like Figures 3 to 4 As shown, both sides of the clamping rod 6 are fixedly connected to the guard plate 13. One end of the guard plate 13 is an arc surface. One side of the double-ended hinge 11 is fixedly connected to the support pad 14, which is located between the two clamping rods 6.

[0044] During operation: When the two clamping rods 6 are flipped, the guard plate 13 ensures that the bearing remains stably positioned between the two clamping rods 6, effectively preventing the bearing from shaking, shifting, or even falling off during the flipping process, thus ensuring a smooth flipping process. The guard plate 13 is made of the same material as the heat source plate 4 and the heat source plate 5, preventing the guard plate 13 from obstructing heat conduction. Furthermore, one end of the guard plate 13 is designed with an arc surface, allowing the bearing to smoothly slide between the two guard plates 13 as it slides down the inclined surface of the inclined platform 2, thus protecting the bearing. Accurate positioning provides convenience, and with the support pad 14, when the outer wall of the bearing is in close contact with the outer wall of the clamping rod 6, the outer wall is supported by the support pad 14, so that each bearing stops at the same position when sliding along the inclined surface of the inclined platform 2, so that the bearing stops just above the heat source plate 4. This effectively avoids the situation where the bearing itself is heavy when flipped to a vertical state, which may force the two clamping rods 6 to spread apart, causing the overall position to drop and fail to be accurately positioned above the heat source plate 5 after flipping.

[0045] It should be noted that the tilt angle of the tilting table 2 is set at about 30 degrees, and the bearing will be subjected to a thrust when it is fed through the feeding assembly. Therefore, when the bearing slides along the surface of the tilting table 2, the initial acceleration it receives is large enough, and under normal circumstances, it can continue to slide along the surface of the tilting table 2.

[0046] like Figures 5 to 8 As shown, the flaring assembly includes two bending plates 15, with a slider 16 fixedly connected between the bottoms of the two bending plates 15. A limit rod 19 is fixedly connected to the inner wall of the slider 16, and a limit seat 20 is symmetrically fixedly connected to the top of the worktable 1. Each limit seat 20 has a sliding rod groove 21 on its inner wall. The limit rod 19 and the sliding rod groove 21 are slidably connected and adapted to each other. A pushing assembly that drives the slider 16 to move upward is provided on one side of the slider 16.

[0047] During operation: When it is necessary to disengage the heated bearing from between the clamping rods 6, the extrusion assembly is activated, generating an upward thrust on the slider 16. The slider 16 moves upward in the vertical direction relative to the tilting platform 2. The limiting rod 19 slides tightly and smoothly within the slide groove 21, ensuring that the slider 16 moves upward in the vertical direction relative to the tilting platform 2. As the slider 16 moves upward in the vertical direction relative to the tilting platform 2, the bending plate 15 also moves upward synchronously, and its bent section begins to contact the outer walls of the two clamping rods 6. The clamping rod 6 applies an outward expansion force. As the expansion force gradually increases, the clamping rod 6 continuously overcomes the elastic force of the torsion spring 12. Under the push of the expansion force, the angle between the two clamping rods 6 continuously increases. As the angle between the clamping rods 6 continues to increase, the bearing will break free from the restraint of the clamping rod 6. When the bending plate 15 continues to move upward, its straight section contacts the clamping rod 6. This process does not apply an expansion force to the clamping rod 6, but increases the tilt angle of the tilting table 3 through the tilting component, making it easier for the bearing to slide down the inclined surface of the tilting table 3 after losing the clamping force.

[0048] like Figure 1 and Figure 5 As shown, the extrusion assembly includes a cylinder 18, which is fixedly installed on the top of the worktable 1. The output shaft of the cylinder 18 is fixedly connected to a triangular slide 17. The triangular slide 17 is slidably connected to the worktable 1. The inclined inner wall of the triangular slide 17 is slidably connected to the outer wall of the slider 16 and they are mutually adapted.

[0049] During operation: When the cylinder 18 is activated, its output shaft extends, which drives the triangular slide 17 to move linearly along the surface of the worktable 1. The inclined surface of the triangular slide 17 will generate an interaction force with the outer wall of the slider 16. The component force perpendicular to the inclined surface will produce an upward squeezing effect on the slider 16. Under the restriction of the limit rod 19 and the slide groove 21, the slider 16 can only move upward in a specific vertical direction, thereby expanding the two clamping rods 6 through the bending plate 15. Conversely, the cylinder 18 retracts, and the bending plate 15 descends to reset. At this time, the unloading work has been completed, and the two clamping rods 6 return to their original shape under the action of the torsion spring 12.

[0050] like Figures 6 to 8 As shown, the tilting assembly includes two circular push blocks 23, which are fixedly connected to one side of the straight section of the bending plate 15. A bearing platform 22 is fixedly connected to the top of the worktable 1, and the shaft of the bearing platform 22 is fixedly connected to the inner wall of the tilting platform 2 3.

[0051] During operation: When the straight section of the bending plate 15 contacts the inner side of the two clamping rods 6, the expansion movement of the clamping rods 6 is completed. The two clamping rods 6 maintain their expanded shape. As the bending plate 15 continues to move upward, the circular push block 23 lifts the tilting platform 2 3 at one end. As the bending plate 15 continues to move upward, the circular push block 23 begins to apply an upward lifting force to the tilting platform 2 3. Under the continuous lifting force of the circular push block 23, the tilting platform 2 3 will rotate around the shaft of the bearing platform 22. According to the lever principle, when the force is applied to one end of the lever, the lever will rotate around the fulcrum. The lifting force of the circular push block 23 causes the tilting platform 2 3 at one end to continue to move upward, while the other end moves downward, thereby achieving a larger overall tilt angle for the tilting platform 2 3.

[0052] like Figures 7 to 8 As shown, a counterweight 24 is fixedly connected to the bottom of one end of the tilting platform 23, and a locking base plate 28 is fixedly connected to one side of the bearing platform 22. The bottom of the locking base plate 28 is attached to the bearing platform 22. A return spring 25 is fixedly connected between the other end of the tilting platform 23 and the bearing platform 22.

[0053] During operation: In the initial state, the tilting platform 23 remains tilted under the gravity of the counterweight 24. The locking base plate 28 positions the tilting platform 23 to prevent shaking. Under the lifting force applied by the circular push block 23, one end of the tilting platform 23 overcomes the gravity of the counterweight 24 and continues to tilt upward, compressing the return spring 25 and causing deformation. After the bending plate 15 descends and returns to its original position, the entire tilting platform 23 is reset under the dual action of the counterweight 24 and the return spring 25. At this time, the bearing is unloaded and the tilting platform 23 returns to its original tilted state.

[0054] like Figures 7 to 8 As shown, an arc-shaped groove 26 is provided on the surface of the inclined platform 23, and an arc-shaped baffle 27 is fixedly connected above the bearing platform 22. The arc-shaped baffle 27 is located inside the arc-shaped groove 26.

[0055] During operation: The arc-shaped baffle 27 restricts the bearing, preventing it from accidentally detaching from the clamping rod 6 and sliding prematurely down the inclined surface of the tilting platform 3 when the bearing is heated above the heat source plate 2 5. This ensures that the bearing has a stable and sufficient heating time. As the tilting platform 2 3 continues to increase its tilt angle, its surface will gradually pass the limit position of the arc-shaped baffle 27. After the tilting angle of the tilting platform 2 3 increases, the bearing can slide down the surface of the tilting platform 2 3 for unloading.

[0056] like Figure 9As shown, the feeding assembly includes a feeding plate 29, which is fixedly connected above the inclined platform 2. Limiting plates 30 are symmetrically fixedly connected to the surface of the feeding plate 29. A rotating plate 31 is symmetrically rotatably connected to the surface of the feeding plate 29. A motor 32 is symmetrically fixedly connected to the bottom of the feeding plate 29. The output shaft of the motor 32 is fixedly connected to the inner wall of the rotating plate 31. A connecting plate 34 is fixedly connected to the side of the feeding plate 29. A connecting rod 33 is inserted into the inner wall of the connecting plate 34. An isolation plate 35 is fixedly connected to one end of the connecting rod 33.

[0057] During operation: In the initial state, a batch of bearings are neatly and evenly arranged on the inclined surface of the feed plate 29. At this time, one end of the rotating plate 31, which is symmetrically connected to the surface of the feed plate 29, just abuts against the bearings, forming an effective restriction and firmly stopping all the bearings to prevent them from sliding down the inclined surface due to their own weight. When the feeding operation is required, the motor 32, which is fixedly connected to the bottom of the feed plate 29 at a symmetrical position, starts to run. Its output shaft drives the rotating plate 31 to start rotating. As the rotating plate 31 rotates, the end that originally restricted the bearings gradually deviates and loses its limiting effect on the bearings. At the same time, the other end of the rotating plate 31 pushes the insertion rod 33 inserted into the inner wall of the connecting plate 34 during the rotation process. The insertion rod 33 slides in the connecting plate 34 under the force, thereby driving the isolation plate 35, which is fixedly connected to it, to move laterally along the surface of the feed plate 29, quickly intercepting the remaining bearings, so that only one bearing is fed at a time.

[0058] like Figure 9 As shown, a return spring 37 is fixedly connected between the plug rod 33 and the connecting plate 34, and a pressing block 36 is fixedly connected to one side of the isolation plate 35.

[0059] During operation: When the feeding stage begins, the partition plate 35 is inserted between the two bearings. At this time, the pressing block 36, fixed to one side of the partition plate 35, plays a crucial role. One end of the pressing block precisely presses the first bearing that is about to move down, applying a stable thrust to the bearing and helping it to move smoothly down the inclined surface of the feeding plate 29, completing the precise feeding action. After the feeding process is completed, the second motor 32 starts and drives the rotating plate 31 to rotate in the opposite direction. The rotating plate 31 gradually resets, returning to the position that limits the bearings. Under the force of the reset spring 37, the partition plate 35 returns to its original position and no longer restricts the subsequent bearings. The subsequent neatly arranged bearings will automatically slide smoothly along the surface of the feeding plate 29 under their own gravity, replenishing the appropriate position in time, and preparing for the next feeding.

[0060] The foregoing has shown and described the basic principles, main features, and advantages of the present invention.
