Description

Technical Field

[0001] This invention relates to the field of support device technology, and in particular to a support device for machining permanent magnet motor rotors. Background Technology

[0002] A support device is a device used in the machining of permanent magnet motor rotors to support the rotor's central shaft. When using a support device, the central shaft of the permanent magnet motor rotor is placed on top of the support frame. This facilitates subsequent welding and component installation of the permanent magnet motor rotor. It can, to some extent, prevent the rotor from moving during machining and effectively support the rotor's central shaft in mid-air, thus facilitating the machining of the permanent magnet motor rotor.

[0003] In their daily work, the inventors discovered that the support device still has at least the following problems: When using the support device, placing the central shaft of the permanent magnet motor rotor on top of the support frame facilitates subsequent welding and component installation of the permanent magnet motor rotor. This can, to some extent, prevent the rotor from moving during processing and effectively support the central shaft of the rotor in mid-air, which is convenient for processing the permanent magnet motor rotor. However, in actual use, because the rotors have different specifications, it is not possible to properly place rotors of different specifications on top of the support frame. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of using a support device where the central shaft of a permanent magnet motor rotor is placed on top of the support frame. This facilitates subsequent welding and component installation of the permanent magnet motor rotor, and to a certain extent, prevents the rotor from shifting during processing. It also effectively supports the central shaft of the rotor in mid-air, which is beneficial for the processing of the permanent magnet motor rotor. However, in actual use, due to the different specifications of the rotors, it is not possible to properly place rotors of different specifications on top of the support frame. Therefore, this invention proposes a support device for processing permanent magnet motor rotors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a support device for processing a permanent magnet motor rotor, comprising a base plate, a support frame uniformly fixedly connected to the top of the base plate, a limiting device provided on the surface of the support frame, the limiting device comprising a sliding plate, a sliding groove provided on the top of the support frame, the inner wall of the sliding groove being slidably connected to the sliding plate, a rubber block fixedly connected to the bottom of the sliding plate, a connecting frame fixedly connected to the bottom of the sliding plate, the connecting frame being slidably fitted onto the surface of the support frame, a first spring uniformly fixedly connected to the bottom of the connecting frame, a support plate fixedly connected to the bottom of the first spring, and the support plate being fixedly connected to one side of the support frame.

[0006] The effect achieved by the above components is as follows: when using the limiting device, after placing the rotor's central shaft on the top of the support frame, manually slide the sliding plate into the sliding groove, thereby causing the rubber block to be pressed against the top of one end of the rotor. This can restrict the rotor to the top of the support frame. By pulling the connecting frame towards the support plate through the first spring, the rubber block is pressed well against the top of one end of the rotor.

[0007] Preferably, a limiting frame is uniformly fixedly connected to the side of the connecting frame near the support frame, a limiting strip is slidably connected to the inner wall of the limiting frame, one side of the limiting strip is fixedly connected to one side of the support frame, a bolt is threaded through one side of the connecting frame, a first rubber plate is provided at one end of the bolt passing through the connecting frame, and one side of the first rubber plate is fixedly connected to one side of the support frame.

[0008] The effect achieved by the above components is that, under the restriction of the limiting strip, the connecting frame can be kept to move vertically up and down. When the sliding plate slides to the appropriate position, the manual control bolt is pressed against one side of the first rubber plate, thereby effectively restricting the sliding plate to the top of one end of the rotor.

[0009] Preferably, the bottom of the support frame is provided with a first movable plate and a second movable plate. A sliding strip is fixedly connected to one side of the first movable plate. The sliding strip is slidably inserted into one side of the second movable plate. A first positioning groove is opened on one side of the sliding strip. A positioning block is slidably connected to the inner wall of the first positioning groove. A rubber triangular block is fixedly connected to the side of the positioning block away from the first positioning groove.

[0010] The effect achieved by the above components is as follows: when using the moving device, the sliding bar is manually controlled to be inserted on one side of the second moving plate, so that the distance between the two support frames can be controlled, which makes it easier to set rotors of different specifications on the top of the support frame. The positioning block is manually controlled to slide to the appropriate position on the inner wall of the first positioning groove, so that the rubber triangular block is pressed into the inner wall of the sliding bar and the second moving plate, which makes it easier to restrict the second moving plate on the surface of the sliding bar.

[0011] Preferably, a conical block is fixedly connected to the top of the positioning block, a rubber ring is sleeved on the surface of the conical block, and a fixing strip is fixedly connected to the side of the sliding strip away from the first positioning groove, and the fixing strip is slidably inserted into one side of the second moving plate.

[0012] The effect achieved by the above components is as follows: when the positioning block slides to the appropriate position on the inner wall of the first positioning groove, the rubber ring is pressed against the top of the sliding strip, which can restrict the positioning block inside the first positioning groove, and the fixing strip can ensure that the sliding strip is set on one side of the inner wall of the second moving plate.

[0013] Preferably, a rotating device is provided on one side of another support frame. The rotating device includes a connecting ring. A rotating groove is formed on the side of the support frame away from the bottom plate. The connecting ring is disposed inside the rotating groove. A semi-circular ring is fixedly connected to the side of the connecting ring away from the rotating groove. Two semi-circular rings are disposed together. A first damping rod is uniformly fixedly connected to the top of the semi-circular ring. The top of the first damping rod is fixedly connected to the bottom of the other semi-circular ring. A second spring is sleeved on the surface of the first damping rod. One end of the second spring is fixedly connected to the top of the semi-circular ring. The end of the second spring near the other semi-circular ring is fixedly connected to the bottom of the other semi-circular ring.

[0014] The effect achieved by the above components is as follows: When using the rotating device, when one end of the rotor is placed between the two semicircular rings, the second spring pulls the semicircular rings towards the support frame, thus restricting one end of the rotor to the middle of the two semicircular rings. When the other end of the rotor is not fixed, the connecting ring is manually controlled to rotate in the inner wall of the rotating groove. This allows the connecting ring to drive the semicircular rings to rotate, which in turn drives the rotor restricted between the two semicircular rings to rotate. This, to a certain extent, can effectively control the rotor to rotate at a suitable angle on the top of the support frame, and can also prevent the rotor from moving left or right to a certain extent.

[0015] Preferably, a second damping rod is fixedly connected to the side of the semicircular ring near the first damping rod, a semicircular plate is fixedly connected to the end of the second damping rod away from the semicircular ring, a second rubber plate is fixedly connected to the side of the semicircular plate near the second damping rod, a third spring is sleeved on the surface of the second damping rod, one end of the third spring is fixedly connected to one side of the inner wall of the semicircular ring, and the end of the third spring near the semicircular plate is fixedly connected to the side of the semicircular plate away from the second rubber plate.

[0016] The effect achieved by the above components is as follows: after one end of the rotor is placed in the middle of the two semicircular rings, the semicircular plate is squeezed towards the rotor by the third spring. This allows the two second rubber plates to be fitted onto the surface of one end of the rotor, which can prevent the rotor from moving in the middle of the two semicircular rings to a certain extent. This prevents the rotor's position from changing when rotating the rotor and affecting the installation of subsequent accessories.

[0017] Preferably, a fixing plate is uniformly fixedly connected to one side of the semi-circular ring, a second positioning groove is provided at the bottom of the fixing plate, a fixing sleeve is slidably connected to the inner wall of the second positioning groove, the fixing sleeve is sleeved on the surface of the two fixing plates, a third damping rod is fixedly connected to one side of the inner wall of the second positioning groove, one end of the third damping rod near the fixing sleeve is fixedly connected to one side of the fixing sleeve, a fourth spring is sleeved on the surface of the third damping rod, one end of the fourth spring is fixedly connected to one side of the inner wall of the second positioning groove, and one end of the fourth spring near the fixing sleeve is fixedly connected to one side of the fixing sleeve.

[0018] The effect achieved by the above components is as follows: the fixing sleeve is fitted onto the surface of the two fixing plates, and the fixing sleeve is pulled towards the semi-circular ring by the fourth spring. This can restrict the fixing sleeve to the surface of the two fixing plates to a certain extent, thereby restricting the two fixing plates together. This can restrict the two semi-circular rings together, so that the connecting ring can rotate well in the inner wall of the rotating groove, thereby avoiding affecting the connecting ring driving the two restricted semi-circular rings to drive the rotor to rotate.

[0019] Preferably, a rubber strip is fixedly connected to the side of the semicircular ring away from the support frame, and a movable strip is provided on the side of the rubber strip away from the semicircular ring. A positioning rod is slidably inserted through one side of the movable strip, one end of the positioning rod is fixedly connected to one side of the support frame, and protrusions are uniformly fixedly connected to the side of the movable strip near the rubber strip. A threaded rod is threadedly inserted through one side of the movable strip, and the threaded rod is rotatably inserted into one side of the support frame.

[0020] The effect achieved by the above components is as follows: when the semicircular ring rotates to the appropriate position, under the restriction of the positioning rod, the threaded rod is manually controlled to rotate, thereby causing the moving bar to move closer to the semicircular ring. This causes the protrusion to press against one side of the rubber strip, resulting in deformation of the rubber strip. This effectively restricts the moving bar to one side of the semicircular ring, and in turn, restricts the semicircular ring to one side of the support frame. This can, to a certain extent, prevent the semicircular ring from rotating when it is not needed, thereby preventing the rotor from moving and affecting the processing when machining the permanent magnet motor rotor.

[0021] In this invention, by setting a limiting device, when using the limiting device, after placing the rotor's central shaft on the top of the support frame, the sliding plate is manually slid into the sliding groove, thereby causing the rubber block to be pressed against the top of one end of the rotor. This can restrict the rotor to the top of the support frame. The connecting frame is pulled towards the support plate by the first spring, thereby causing the rubber block to be pressed against the top of one end of the rotor. Attached Figure Description

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this invention. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0034] The implementation of the present invention will be described in detail below with reference to specific embodiments.

[0035] like Figure 1-9 As shown, a support device for processing a permanent magnet motor rotor has a support frame 2 evenly fixedly connected to the top of the base plate 1. The surface of the support frame 2 is provided with a limiting device 3. When using the support device, the central shaft of the permanent magnet motor rotor is placed on the top of the support frame 2. This facilitates the subsequent welding of the permanent magnet motor rotor and the installation of components. This can, to a certain extent, prevent the rotor from moving during processing and effectively support the central shaft of the rotor in mid-air, which facilitates the processing of the permanent magnet motor rotor.

[0036] reference Figures 2 to 4The limiting device 3 includes a sliding plate 302. A sliding groove 301 is provided on the top of the support frame 2. The inner wall of the sliding groove 301 is slidably connected to the sliding plate 302. A rubber block 303 is fixedly connected to the bottom of the sliding plate 302. A connecting frame 304 is fixedly connected to the bottom of the sliding plate 302. The connecting frame 304 is slidably fitted onto the surface of the support frame 2. A first spring 306 is evenly fixedly connected to the bottom of the connecting frame 304. A support plate 305 is fixedly connected to the bottom of the first spring 306. The support plate 305 is fixedly connected to one side of the support frame 2. When using the limiting device 3, after placing the rotor's central shaft on the top of the support frame 2, the sliding plate 302 is manually slid into the sliding groove 301, causing the rubber block 303 to press against the top of one end of the rotor. The rotor is confined to the top of the support frame 2. The first spring 306 pulls the connecting frame 304 towards the support plate 305, causing the rubber block 303 to press firmly against the top of one end of the rotor. A limit frame 307 is evenly fixedly connected to the side of the connecting frame 304 near the support frame 2. A limit strip 308 is slidably connected to the inner wall of the limit frame 307. One side of the limit strip 308 is fixedly connected to one side of the support frame 2. A bolt 309 is threaded through one side of the connecting frame 304. A first rubber plate 310 is provided at one end of the bolt 309, which passes through the connecting frame 304. One side of the first rubber plate 310 is fixedly connected to one side of the support frame 2. Under the constraint of the limit strip 308, the connecting frame 304 remains vertical. The sliding plate 302 moves downwards, and when it slides to the appropriate position, the manual control bolt 309 presses against one side of the first rubber plate 310, thus effectively restricting the sliding plate 302 to the top of one end of the rotor. The bottom of the support frame 2 is provided with a first moving plate 311 and a second moving plate 312. A sliding strip 313 is fixedly connected to one side of the first moving plate 311, and the sliding strip 313 is slidably inserted into one side of the second moving plate 312. A first positioning groove 314 is opened on one side of the sliding strip 313, and a positioning block 315 is slidably connected to the inner wall of the first positioning groove 314. A rubber triangular block 316 is fixedly connected to the side of the positioning block 315 away from the first positioning groove 314. The manual control allows the sliding strip 313 to be inserted into one side of the second moving plate 312, thus enabling… The distance between the two support frames 2 is controlled to facilitate the placement of rotors of different specifications on the top of the support frames 2. The positioning block 315 is manually controlled to slide to a suitable position on the inner wall of the first positioning groove 314, thereby causing the rubber triangular block 316 to be pressed into the inner wall of the sliding strip 313 and the second moving plate 312. This helps to restrict the second moving plate 312 to the surface of the sliding strip 313. A conical block 317 is fixedly connected to the top of the positioning block 315, and a rubber ring 318 is fitted on the surface of the conical block 317. A fixing strip 319 is fixedly connected to the side of the sliding strip 313 away from the first positioning groove 314. The fixing strip 319 is slidably inserted into one side of the second moving plate 312. When the positioning block 315 slides to a suitable position on the inner wall of the first positioning groove 314...The rubber ring 318 is pressed against the top of the sliding strip 313, thus confining the positioning block 315 inside the first positioning groove 314. The fixing strip 319 ensures that the sliding strip 313 is positioned on one side of the inner wall of the second moving plate 312.

[0037] Reference Figures 5 to 9A rotating device 4 is provided on one side of another support frame 2. The rotating device 4 includes a connecting ring 402. A rotating groove 401 is opened on the side of the support frame 2 away from the bottom plate 1. The connecting ring 402 is disposed inside the rotating groove 401. A semi-circular ring 403 is fixedly connected to the side of the connecting ring 402 away from the rotating groove 401. Two semi-circular rings 403 are arranged together. A first damping rod 404 is evenly fixedly connected to the top of the semi-circular ring 403. The top of the first damping rod 404 is fixedly connected to the bottom of the other semi-circular ring 403. A second spring 405 is sleeved on the surface of the first damping rod 404. One end of the second spring 405 is fixedly connected to the top of the semi-circular ring 403. The end of the second spring 405 near the other semi-circular ring 403 is fixedly connected to the other semi-circular ring 403. The bottom is fixedly connected. When using the rotating device 4, if one end of the rotor is placed between the two semicircular rings 403, the second spring 405 pulls the semicircular rings 403 towards the support frame 2, thus restricting one end of the rotor to the middle of the two semicircular rings 403. When the other end of the rotor is not fixed, the connecting ring 402 is manually controlled to rotate in the inner wall of the rotating groove 401, which can effectively drive the rotor to rotate and thus prevent the rotor from moving left and right to a certain extent. A second damping rod 406 is fixedly connected to the side of the semicircular ring 403 near the first damping rod 404. A semicircular plate 408 is fixedly connected to the end of the second damping rod 406 away from the semicircular ring 403. The side of the semicircular plate 408 near the second damping rod 406 is fixedly connected to the second damping rod 406. A second rubber plate 409 is fixedly connected to the surface of the second damping rod 406, and a third spring 407 is fitted onto the surface of the second damping rod 406. One end of the third spring 407 is fixedly connected to one side of the inner wall of the semicircular ring 403, and the end of the third spring 407 near the semicircular plate 408 is fixedly connected to the side of the semicircular plate 408 away from the second rubber plate 409. After one end of the rotor is placed in the middle of the two semicircular rings 403, the third spring 407 presses the semicircular plate 408 towards the rotor, so that the two second rubber plates 409 are fitted onto the surface of one end of the rotor. This can, to a certain extent, prevent the rotor from moving in the middle of the two semicircular rings 403. A fixing plate 410 is evenly fixedly connected to one side of the semicircular ring 403, and a second damping rod 410 is opened at the bottom of the fixing plate 410. The second positioning groove 411 has a slidably connected fixing sleeve 412 on its inner wall. The fixing sleeve 412 is fitted onto the surfaces of the two fixing plates 410. A third damping rod 413 is fixedly connected to one side of the inner wall of the second positioning groove 411. The end of the third damping rod 413 near the fixing sleeve 412 is fixedly connected to one side of the fixing sleeve 412. A fourth spring 414 is fitted onto the surface of the third damping rod 413. One end of the fourth spring 414 is fixedly connected to one side of the inner wall of the second positioning groove 411. The end of the fourth spring 414 near the fixing sleeve 412 is fixedly connected to one side of the fixing sleeve 412. When the fixing sleeve 412 is fitted onto the surfaces of the two fixing plates 410, the fourth spring 414 pulls the fixing sleeve 412 toward the semicircular ring 403.This design can, to a certain extent, restrict the fixing sleeve 412 to the surface of the two fixing plates 410, thereby restricting the two fixing plates 410 together. This also restricts the two semicircular rings 403 together. A rubber strip 415 is fixedly connected to the side of the semicircular ring 403 away from the support frame 2. A movable strip 419 is provided on the side of the rubber strip 415 away from the semicircular ring 403. A positioning rod 416 is slidably inserted through one side of the movable strip 419. One end of the positioning rod 416 is fixedly connected to one side of the support frame 2. Protrusions 418 are evenly fixedly connected to the side of the movable strip 419 near the rubber strip 415. A threaded rod 417 is threadedly inserted through one side of the movable strip 419. The threaded rod 417 is rotatably inserted into... On one side of support frame 2, when the semicircular ring 403 rotates to the appropriate position, under the constraint of positioning rod 416, the threaded rod 417 is manually controlled to rotate, thereby causing the moving strip 419 to move closer to the semicircular ring 403. This causes the protrusion 418 to press against one side of the rubber strip 415, deforming the rubber strip 415. This effectively restricts the moving strip 419 to one side of the semicircular ring 403, thus restricting the semicircular ring 403 to one side of support frame 2. This can, to a certain extent, prevent the semicircular ring 403 from rotating when it is not needed, thereby preventing rotor movement during the machining of the permanent magnet motor rotor and affecting the machining process.

[0038] Working principle: When using the support device, the central shaft of the permanent magnet motor rotor is placed on top of the support frame 2. This facilitates subsequent welding and component installation of the permanent magnet motor rotor, and to a certain extent, prevents the rotor from moving during processing. It also effectively supports the central shaft of the rotor in mid-air, facilitating the processing of the permanent magnet motor rotor. When using the limiting device 3, after placing the central shaft of the rotor on top of the support frame 2, the sliding plate 302 is manually slid into the sliding groove 301, causing the rubber block 303 to press against the top of one end of the rotor. This restricts the rotor to the top of the support frame 2. The first spring 306 pulls the connecting frame 304 towards the support plate 305, thereby causing the rubber block 303 to... The rubber ring 309 is pressed firmly against the top of one end of the rotor. Under the constraint of the limiting strip 308, the connecting frame 304 can move vertically up and down. When the sliding plate 302 slides to the appropriate position, the manual control bolt 309 presses against one side of the first rubber plate 310, thus effectively restricting the sliding plate 302 to the top of one end of the rotor. The manual control positioning block 315 slides to the appropriate position on the inner wall of the first positioning groove 314, thus pressing the rubber triangular block 316 into the inner wall of the sliding strip 313 and the second moving plate 312. This facilitates the restriction of the second moving plate 312 on the surface of the sliding strip 313. When the positioning block 315 slides to the appropriate position on the inner wall of the first positioning groove 314, the rubber ring 318 presses against the top of the sliding strip 313. This design allows the positioning block 315 to be confined inside the first positioning groove 314. The fixing strip 319 ensures that the sliding strip 313 is positioned on one side of the inner wall of the second moving plate 312. When using the rotating device 4, if one end of the rotor is placed between the two semicircular rings 403, the second spring 405 pulls the semicircular rings 403 towards the support frame 2, thus confining one end of the rotor in the middle of the two semicircular rings 403. After placing one end of the rotor in the middle of the two semicircular rings 403, the fixing sleeve 412 is fitted onto the surface of the two fixing plates 410. The fourth spring 414 pulls the fixing sleeve 412 towards the semicircular rings 403, thus confining the fixing sleeve 412 to a certain extent within the two fixing plates 410. The surface of the fixed plate 410 is used to constrain the two fixed plates 410 together, thus constraining the two semicircular rings 403 together. The third spring 407 presses the semicircular plate 408 towards the rotor, allowing the two second rubber plates 409 to be fitted onto the surface of one end of the rotor. This helps to prevent the rotor from moving between the two semicircular rings 403. When the other end of the rotor is not fixed, the connecting ring 402 is manually controlled to rotate within the inner wall of the rotating groove 401, effectively driving the rotor to rotate. When the semicircular ring 403 rotates to the appropriate position, the threaded rod 417 is manually controlled to rotate under the constraint of the positioning rod 416, causing the moving strip 419 to move towards the semicircular ring 403.This causes the protrusion 418 to press against one side of the rubber strip 415, deforming the rubber strip 415. This effectively confines the moving strip 419 to one side of the semi-circular ring 403, and consequently, confines the semi-circular ring 403 to one side of the support frame 2, thus preventing the rotor from moving left or right to a certain extent.

[0039] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
