Description

Technical Field

[0001] The present invention belongs to the technical field of motor rotor processing, and particularly relates to a rotor turning device. Background Art

[0002] A motor rotor refers to the rotating part of a motor and is an indispensable component of the motor. During the rotor processing, turning operations need to be performed on it, which are mainly used for surface polishing, cutting or pressing of the motor rotor to remove irregular or uneven parts on its surface, thereby ensuring the accuracy and quality of the rotor.

[0003] In the application document with the publication number CN116079081A, a turning device is disclosed. The device includes: a turning structure composed of a support mechanism and a turning tool. A rotating groove is provided on the support mechanism, and there are two support mechanisms spaced apart. Both ends of the target are rotatably installed in these two rotating grooves, and the turning tool is located between the two support mechanisms, with one end thereof abutting against the target for turning; and a driving structure located above the target for driving the target to rotate. This application document aims to improve the convenience of installation and disassembly of the rotor shaft and enhance the processing efficiency.

[0004] However, the support mechanism of the existing rotor turning device usually only supports the rotor through the opened rotating groove. When turning rotors of different specifications, due to the diameter difference of the rotor shafts, after the rotor is placed in the rotating groove, the axis height thereof will change accordingly. This causes the turning tool to be unable to always feed accurately along the diameter direction of the rotor, resulting in possible deviations during rotor turning and unable to guarantee the turning accuracy. In particular, when turning small batches of rotors with diverse specifications, the existing turning device often needs to stop several times to adjust the height of the support mechanism or the turning tool to ensure accurate radial feeding during turning. Summary of the Invention

[0005] The purpose of the present invention is to provide a rotor turning device, aiming to solve the problem that in the prior art, when turning small batches of rotors with different specifications, it is necessary to stop several times to adjust the height of the support mechanism or the turning tool in order to ensure radial feeding along the rotor during rotor turning.

[0006] To achieve the above purpose, the present invention provides the following technical solution: a rotor turning device, including a workbench and a support mechanism, a turning mechanism and a pressing arm mechanism located on the upper surface of the workbench. The support mechanism includes a mounting plate, two support blocks respectively located at both ends of the top of the mounting plate, a support member and a driving member.

[0007] The support member includes a support plate located above the support block and parallel to its top surface, and two clamping plates extending along the vertical direction of the support block. Both clamping plates can slide in the left-right direction of the support block.

[0008] The driving member includes an electric telescopic rod installed on the support block and a transmission member. The electric telescopic rod is used to drive the support plate to move up and down, and the transmission member is used to drive the two clamping plates to approach or separate from each other when the telescopic end of the electric telescopic rod expands and contracts. In particular, for every unit length increase or decrease of the support plate, each clamping plate will correspondingly move one unit length.

[0009] The beneficial effect of the present invention is that by providing the support plate and the two clamping plates, during the turning of the rotor, the driving member can be controlled to drive the support plate to rise while also driving the two clamping plates to approach each other. When the support plate rises by one unit length, each clamping plate also correspondingly moves one unit length. When the two clamping plates just come into contact with the outer wall of the rotor shaft and clamp the rotor shaft, the support plate also just lifts the rotor to a height where its axis is consistent with the feed direction of the turning tool. Therefore, after the support plate and the two clamping plates clamp the rotor shaft, regardless of the diameter of the rotor shaft, the clamped rotor will be exactly in the feed direction of the turning tool radially. In this way, the device can clamp and turn rotors of different specifications without adjusting the height of the support mechanism or the turning tool, thereby improving the convenience of clamping during the turning of rotors of different specifications and also enhancing the turning efficiency.

[0010] A card slot extending in the front-rear direction is provided at the top of the support block, and an installation slot extending in the left-right direction is provided in the middle of the top end of the card slot. Clamping slots extending in the left-right direction are provided at both the left and right ends of the support plate. The two clamping plates are respectively located in the two clamping slots and can move in the left-right direction of the clamping slots.

[0011] A rotating slot is provided in the middle of the bottom wall of the installation slot, and an installation hole coaxial with it is provided in the middle of the bottom end of the rotating slot. Guide slots extending in the left-right direction are provided on the front side and the rear side of the bottom wall of the installation slot. The middle parts of the two guide slots communicate with the rotating slot. The electric telescopic rod is fixedly installed in the installation hole, and its telescopic end is fixedly connected to the middle of the bottom surface of the support plate. The rotating slot and the guide slots are used to install the transmission member.

[0012] The transmission member includes a gear rotatably installed in the rotation groove and coaxial with it, and two racks slidably installed in two guide grooves in the left - right direction respectively. Both racks are meshed with the gear, and the mutually - remote ends of the two racks are respectively fixedly connected to the bottoms of the two clamping plates. The telescopic end of the electric telescopic rod slidably penetrates through the gear and is fixedly connected to the middle of the bottom end of the support plate. At the same time, a helically - extending transmission groove is formed on the outer wall of the telescopic end of the electric telescopic rod, and a transmission block is fixedly installed on the inner ring wall of the gear, and the transmission block is slidably sleeved in the transmission groove.

[0013] The effect is that by setting the transmission member, when the driving member drives the support plate to rise, it can drive the two clamping plates to approach each other simultaneously, and the moving distance of a single clamping plate is the same as the rising distance of the support plate, so as to ensure that the axis of the rotor after clamping is exactly in the feed direction of the turning tool.

[0014] Two pressing plates extending in the left - right direction are fixedly installed at the top of the rotation groove, and the two pressing plates are symmetrically arranged on the front side and the rear side of the telescopic end of the electric telescopic rod.

[0015] The effect is that it can prevent the gear from rising synchronously with the telescopic end of the electric telescopic rod, so as to ensure that while the electric telescopic rod drives the support plate to rise, it can smoothly drive the two clamping plates to approach each other.

[0016] Arc - shaped grooves extending in the front - rear direction of the support block are formed in the middle of the top surface of the support plate and at the top of the relative sides of the two clamping plates. Rotating columns with axes extending in the front - rear direction of the support block are rotatably installed on both sides of the arc - shaped groove.

[0017] The effect is that by setting the arc - shaped groove and the rotating column, after the two clamping plates clamp the rotor, it can avoid the situation that the rotor cannot be driven to rotate by the pressing arm mechanism due to the clamping force, or reduce the friction between the rotor and the two clamping plates when the rotor rotates, preventing the rotor from being damaged.

[0018] First limiting grooves extending in the vertical direction are formed on the front and rear side walls of the two clamping plates, and second limiting grooves extending in the left - right direction are formed at the corresponding positions on the front and rear side walls of the two clamping grooves. A limiting block is slidably sleeved inside the first limiting groove, and one end of the limiting block extends into the second limiting groove adjacent to and corresponding to it and is slidably connected to the second limiting groove.

[0019] The effect is that by setting the limiting mechanism composed of the first limiting groove, the second limiting groove and the limiting block, it can effectively limit the two clamping plates, ensuring that the two clamping plates always remain vertical during the process of approaching or separating from each other, and avoiding the situation that they cannot accurately clamp the rotor because they cannot keep parallel to each other.

[0020] The turning mechanism includes a first linear module extending in the front-rear direction. A second linear module extending in the left-right direction is installed on the first linear module. A tool holder is fixedly installed at one end of the second linear module close to the support mechanism, and a turning tool is installed on the tool holder.

[0021] The pressing arm mechanism includes a spindle box. A support arm is installed on one side of the spindle box. One end of the support arm is hinged to the outer wall of the spindle box, and the other end of the support arm extends above the support mechanism. The spindle axis of the spindle box extends in the front-rear direction and a driving wheel is fixedly installed. A driven wheel is rotatably installed at the end of the support arm far from the spindle box, and a tensioning wheel is rotatably installed in the middle of the support arm. A transmission belt is connected between the driving wheel and the driven wheel.

[0022] The support mechanism further includes a positioning member, which is fixedly installed on the top surface of the workbench and located at one end of the mounting plate, and is used to abut against one end of the rotor shaft when clamping the rotor.

[0023] Compared with the prior art, the beneficial effects of the present invention are: 1. When the support plate rises, it can also drive the two clamping plates to approach each other, and the moving distance of a single clamping plate is the same as the rising distance of the support plate. Furthermore, the shaft of the rotor can be clamped. After clamping, the axis of the rotor is just in the feed direction of the turning tool. Therefore, the device can turn rotors of different specifications without additionally adjusting the height of the support mechanism or the turning tool, improving the convenience of clamping the rotor when turning rotors of different specifications by the device. At the same time, the turning efficiency when turning rotors of different specifications by the device is also improved.

[0024] 2. By setting the arc-shaped groove and the rotating column, it can be avoided that after the two clamping plates clamp the rotor, due to the clamping force, the rotor cannot be smoothly driven to rotate by the pressing arm mechanism, or the friction between the rotor and the two clamping plates during rotation of the rotor is reduced, preventing the rotor from being damaged.

Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] Please refer to Figures 1-7 , the present invention provides the following technical solutions: A rotor turning device includes a seat body 1, a workbench 2, a support mechanism 3, a turning mechanism 4, a pressing arm mechanism 5, and a control mechanism 6. The workbench 2 is arranged on the top of the seat body 1. The support mechanism 3, the turning mechanism 4, the pressing arm mechanism 5, and the control mechanism 6 are all installed on the workbench 2, and the support mechanism 3 is located between the turning mechanism 4 and the pressing arm mechanism 5. The support mechanism 3 is used to support the rotor to be turned. The turning mechanism 4 is used to perform turning processing on the rotor. The pressing arm mechanism 5 is used to press the rotor against the support mechanism 3 and drive the rotor to rotate. The control mechanism 6 controls the entire turning process of the device.

[0029] Refer to Figure 2 As shown, the turning mechanism 4 is mainly composed of a first linear module 41. A second linear module 42 is installed on the first linear module 41. A tool holder 43 is fixedly installed at one end of the second linear module 42 close to the support mechanism 3. A turning tool 44 is installed on the tool holder 43. The cutting edge of the turning tool 44 faces the support mechanism 3. In this embodiment, when the first linear module 41 drives the second linear module 42 to perform a linear motion along the front and back direction of the workbench 2, the second linear module 42 will further drive the tool holder 43 to perform a linear motion along the left and right direction of the workbench 2. Of course, in other embodiments, there is also a situation where the first linear module 41 drives the second linear module 42 to move along the left and right direction of the workbench 2 (i.e., Figure 1in the left - right direction), while the second linear module 42 drives the tool holder 43 to move in the front - back direction of the workbench 2 (i.e., Figure 2 in the left - right direction).

[0030] Refer to Figure 2 As shown, the pressing arm mechanism 5 includes a spindle box 51. On one side of the spindle box 51, a support arm 52 is fixedly installed. One end of the support arm 52 is connected to the outer wall of the spindle box 51 through a hinge, and the other end of the support arm 52 extends above the support mechanism 3. The spindle inside the spindle box 51 extends in the front - back direction, and a driving wheel 53 is fixedly installed on its axis. At the end of the support arm 52 far from the spindle box 51, a driven wheel 54 is rotatably installed. The driving wheel 53 and the driven wheel 54 are connected by a transmission belt 56, and the transmission belt 56 is made of rubber material. In addition, a tensioning wheel 55 is installed in the middle of the support arm 52. The bottom of the tensioning wheel 55 contacts the transmission belt 56 and has a certain elasticity. A dedicated driving mechanism is provided on the workbench 2 to drive the support arm 52 to rotate. When turning the rotor, the driving mechanism is started to drive the support arm 52 to rotate, so that the other end of the support arm 52 (i.e., the end with the driven wheel 54 installed) rotates towards the support mechanism 3. This action causes the transmission belt 56 to contact the outer circumferential surface of the rotor and simultaneously drives the tensioning wheel 55 to move downward. At this time, under the action of the tensioning wheel 55, the transmission belt 56 can closely fit on the rotor and press it against the support mechanism 3. At the same time, due to the transmission relationship between the transmission belt 56 and the driving wheel 53 and the driven wheel 54, it can effectively drive the rotor to rotate.

[0031] Refer to Figures 2-7 As shown, the support mechanism 3 includes a mounting plate 31, a support block 32, a support member 33, a driving member 34, and a positioning member 35.

[0032] Refer to Figure 2 As shown, the mounting plate 31 is a rectangular plate, and its length direction extends along the front - back direction. The positioning member 35 is arranged in front of or behind the mounting plate 31. In this embodiment, the positioning member 35 is specifically located behind the mounting plate 31, and its main function is to abut against one end of the rotor shaft. In addition, there are two support blocks 32, which are respectively installed on the front side and the rear side of the top surface of the mounting plate 31.

[0033] Refer to Figure 5 and Figure 6As shown, a clamping groove 321 is formed at the top of the support block 32. The clamping groove 321 extends along the front-back direction of the support block 32 and is used to accommodate the rotating shaft of the rotor. In this embodiment, the clamping groove 321 is designed as an isosceles trapezoidal groove that is wider at the top and narrower at the bottom to adapt to rotating shafts of different sizes. However, in other embodiments, the clamping groove 321 can also be designed as a rectangular groove. In the middle of the top end of the clamping groove 321, an installation groove 322 is formed, which extends along the left-right direction of the support block 32 and is used to install the support member 33. In the middle of the bottom wall of the installation groove 322, a rotating groove 324 is formed, and in the middle of the bottom end of the rotating groove 324, a coaxial installation hole 325 is formed. In addition, on the front side and the rear side of the bottom wall of the installation groove 322, a guiding groove 323 is formed along the left-right direction. The middle parts of these two guiding grooves 323 are connected to the rotating groove 324. The guiding grooves 323, the rotating groove 324, and the installation hole 325 together constitute the structural basis for installing the driving member 34.

[0034] Reference Figure 4 and Figure 7 As shown in and, the support member 33 includes a support plate 331 slidably installed in the installation groove 322, and the support plate 331 is parallel to the bottom surface of the installation groove 322. The support plate 331 is rectangular, and its length direction extends along the left-right direction of the support block 32. The support plate 331 can slide in the vertical direction of the support block 32. At both ends of the support plate 331, a clamping groove 332 extending along the left-right direction is formed, and a clamping plate 333 is provided in each of these two clamping grooves 332. The clamping plate 333 is also rectangular, but its length direction extends along the vertical direction of the support block 32.

[0035] In the middle of the top surface of the support plate 331 and at the top of the relative sides of the two clamping plates 333, an arc-shaped groove 334 extending along the front-back direction of the support block 32 is formed. These arc-shaped grooves 334 are located in the same circumferential direction, that is, they are arranged around a hypothetical center together. On both sides of the arc-shaped groove 334, a rotating column 335 is rotatably installed, and the axes of these rotating columns 335 extend along the front-back direction of the support block 32. After the clamping plate 333 clamps the rotating shaft of the rotor, the rotating column 335 can ensure that the rotor rotates smoothly driven by the transmission belt 56, thereby reducing the friction force on the rotating shaft of the rotor during rotation.

[0036] On the front and rear side walls of both clamping plates 333, first limiting grooves 336 extending in the vertical direction are provided. At the same time, on the front and rear side walls of both clamping grooves 332, second limiting grooves 337 extending in the left - right direction are provided. Inside these first limiting grooves 336, limiting blocks 338 are slidably sleeved. One end of the limiting block 338 extends into the second limiting groove 337 adjacent to it and forms a sliding connection with the second limiting groove 337. Importantly, the movement of the limiting block 338 is strictly restricted: it can only slide vertically along the first limiting groove 336 and can also slide horizontally along the second limiting groove 337. Such a design can effectively limit the support plate 331 and the clamping plate 333 to ensure that they can always maintain a perpendicular state to each other.

[0037] Through holes 326 are provided at the four corners of the bottom surface of the installation groove 322, and the axes of these through holes 326 extend along the vertical direction of the support block 32. Inside each through hole 326, a guiding column 339 is slidably sleeved. The top end of the guiding column 339 is fixedly connected to the bottom surface of the support plate 331. The main function of these guiding columns 339 is to limit and guide the movement of the support plate 331 to ensure that the support plate 331 can only move vertically along the support block 32. At the same time, due to the guiding effect of the guiding column 339, the support plate 331 can always remain parallel to the bottom surface of the installation groove 322 during the movement.

[0038] Reference Figure 4 、 Figure 6 and Figure 7 As shown in

[0039] The driving member 34 includes an electric telescopic rod 341 installed in the installation hole 325 and a transmission member installed in the rotation groove 324. The electric telescopic rod 341 is used to drive the support plate 331 to move up and down, and the transmission member is used to drive the two clamping plates 333 to approach or move away from each other when the electric telescopic rod 341 expands and contracts.

[0040] When the telescopic end of the electric telescopic rod 341 expands and contracts, the transmission block 345 slides in the transmission groove 344, and then drives the gear 342 to rotate under the action of the transmission groove 344. It should be noted that for every unit length of expansion and contraction of the telescopic end of the electric telescopic rod 341, the gear 342 can rotate and drive the rack 343 to slide a corresponding unit length. Therefore, when the support plate 331 rises by one unit length under the action of the electric telescopic rod 341, each clamping plate 333 will move one unit length towards the center of the installation groove 322 (i.e., the direction of the rotor).

[0041] When the two clamping plates 333 just come into contact with the outer wall of the rotor shaft and clamp the rotor shaft, the support plate 331 just lifts the rotor to a height where its axis is consistent with the feed direction of the turning tool 44. At this time, the rotor shaft also just coincides with the arc-shaped grooves 334 formed on the support plate 331 and the two clamping plates 333. At the same time, the rotating columns 335 at both ends of the arc-shaped groove 334 just abut against the outer wall of the rotor shaft. In this way, the rotating columns 335 at both ends of the three arc-shaped grooves 334 can not only clamp the rotor shaft, but also do not affect the rotation of the rotor shaft.

[0042] At the top of the rotating groove 324, two pressing plates 346 extending in the left-right direction are fixedly installed. The two pressing plates 346 are symmetrically arranged on the front side and the rear side of the telescopic end of the electric telescopic rod 341, and are used to prevent the gear 342 from moving out of the rotating groove 324 under the action of the electric telescopic rod 341.

[0043] The implementation principle of the embodiment of the present invention is as follows: When turning the rotor, the rotor needs to be placed on two support blocks 32, ensuring that both ends of the rotating shaft of the rotor are respectively embedded in the card slots 321 on the top surfaces of the two support blocks 32, and the rotor is located on the top surface of the support plate 331. At the same time, one end of the rotating shaft should be closely attached to the positioning member 35. Subsequently, start the electric telescopic rod 341, and make its telescopic end extend, thereby driving the support plate 331 to rise, and the support plate 331 drives the rotor to rise synchronously. During the process of the telescopic end of the electric telescopic rod 341 extending, it passes through the gear 342. At this time, the transmission block 345 on the inner ring wall of the gear 342 will slide in the transmission groove 344 on the outer wall of the telescopic end of the electric telescopic rod 341, thereby driving the gear 342 to rotate. As the gear 342 rotates, through the meshing connection with the two racks 343, the gear 342 drives the two clamping plates 333 to approach each other. When the two clamping plates 333 clamp the outer circular surface of the rotor, the rotating columns 335 on the support plate 331 and the two clamping plates 333 are all in close contact with the outer circular surface of the rotor. At this time, the feeding direction of the turning tool 44 exactly coincides with the radial direction of the rotor. It should be noted that since each clamping plate 333 moves a corresponding unit length towards the rotor when the support plate 331 rises by one unit length, when turning rotors of different specifications, through the clamping action of the two clamping plates 333 and the support plate 331, it can ensure that the feeding direction of the turning tool 44 always remains consistent with the radial direction of the rotor.

[0044] Then start the driving mechanism to drive the support arm 52 to rotate. As one end of the support arm 52 rotates, it gradually moves towards the support mechanism 3, thereby making the transmission belt 56 in close contact with the outer circular surface of the rotor. Under the action of the tensioning pulley 55, the transmission belt 56 can stably drive the rotor to rotate. Then, start the first linear module 41 and the second linear module 42, and let them cooperate with each other to drive the turning tool 44 to precisely machine the outer circular surface of the rotor.

[0045] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limitations on the present invention.
