Description

Technical Field

[0001] The invention relates to the technical field of motor manufacturing, in particular to a motor rotor for an unmanned aerial vehicle and a processing device thereof. Background Art

[0002] In the known technology, the power system of the UAV mainly includes four parts: a motor, an electronic speed regulator, a propeller and a battery. Among them, the motor of the UAV is the same as a general motor, and is mainly composed of a stator and a rotor. The rotor core and the rotating shaft are the main components of the motor rotor. During the processing of the motor rotor, the rotating shaft needs to be inserted into the rotor core and pressed tightly before the next processing operation can be carried out; and the process of inserting the rotor core into the rotating shaft is generally to use a press to directly press the rotating shaft into the inner side of the shaftless rotor core. This assembly processing method will cause damage to the rotor core and the rotating shaft, thereby affecting the subsequent use of the motor rotor; therefore, in order to avoid damage to the rotor core and the rotating shaft and improve the assembly effect, it is necessary to heat the rotor core before assembling the rotor core and the rotating shaft. After the rotor core expands due to heat, the inner diameter expands to facilitate the insertion and assembly of the rotating shaft. After the rotor core cools, the rotor core contracts to achieve a close fit with the rotating shaft.

[0003] No matter the method of directly inserting the shaft into the inner side of the rotor core or inserting the shaft after the rotor core is heated, the loading and unloading processes of the rotor core and the shaft are inseparable. After the operator aligns the rotor core and the shaft, the operator will drive the press to push the shaft into the inner side of the rotor core. After completing the assembly of a single rotor core and the shaft, the operator will remove the connected rotor core and shaft before preparing for loading and subsequent assembly of a new rotor core and shaft. This process is repeated to achieve the sequential plug-in assembly of the shaft and the rotor core. Due to the delay in loading and unloading of the rotor core and the shaft, the current assembly efficiency of the rotor core and the shaft is still relatively low. Summary of the invention

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0025] like Figures 1 to 5 As shown, the present invention includes the following embodiments:

[0026] Embodiment 1: A motor rotor processing equipment for drones, comprising a base 1 and a support leg 11 on the lower surface of the base 1; the upper surface of the base 1 is fixedly connected to a heating box 2; a heating tank 21 is provided in the heating box 2; hot oil is contained in the heating tank 21; a rotating tank 22 connected to the heating tank 21 is provided on the upper surface of the heating box 2; a first rotating disk 3 is rotatably sealed and connected in the rotating tank 22; the outer side of the heating box 2 is rotatably connected to a second rotating disk 4; the central axes of the first rotating disk 3 and the second rotating disk 4 coincide with each other and are parallel to the horizontal plane; the first rotating disk 3 is centrally connected to the second rotating disk 4; the first rotating disk 3 rotates around the center The first placement holes 31 are evenly arranged throughout; the second turntable 4 is evenly arranged with second placement holes 41 corresponding to the first placement holes 31 around the center; the inner diameter of the first placement holes 31 is adapted to the outer diameter of the rotor core; the inner diameter of the second placement holes 41 is adapted to the outer diameter of the shaft; the second turntable 4 is fixedly connected to the driving motor 5 at the center of the side facing away from the first turntable 3; the driving motor 5 is fixedly connected to the upper surface of the base 1 through the bracket 51; the second turntable 4 is tiltedly provided with an oblique ring 6 on the side facing away from the first turntable 3; the distance between the upper part of the oblique ring 6 and the second turntable 4 is smaller than the distance between the lower part and the second turntable 4.

[0027] In this embodiment, a slide groove 12 is provided on the upper surface of the base 1; an L-shaped block 13 is slidably connected in the slide groove 12; the upper end of the L-shaped block 13 is fixedly connected to the lower part of the bevel ring 6; a threaded hole 14 is provided through the upper and lower ends of the L-shaped block 13; a bolt 15 is threadedly connected to the threaded hole 14; the sliding direction of the L-shaped block 13 in the slide groove 12 is consistent with the axial direction of the first turntable 3.

[0028] After the staff moves the rotor core formed by stacking silicon steel sheets to the left side of the processing equipment, the staff moves the shaft to the right side of the processing equipment, loosens the bolt 15, and makes the bolt 15 disengage from the contact with the bottom of the slide slot 12, thereby unlocking the L-shaped block 13, and then pushes the L-shaped block 13 along the slide slot 12 to move closer to or away from the second turntable 4, and adjusts the position of the L-shaped block 13 in the slide slot 12 according to the depth of the shaft inserted into the rotor core. If it is necessary to control the shaft to be inserted deeper into the inner side of the rotor core, it is necessary to control the L-shaped block 13 to be close to the second turntable 4, otherwise, control the L-shaped block 13 to be away from the second turntable 4. The movement of the L-shaped block 13 will drive the bevel ring 6 to move synchronously. After the position adjustment of the L-shaped block 13 is completed, the bolt 15 is tightened so that the bolt 15 is against the bottom of the slide slot 12 to lock the L-shaped block 13, so that the processing equipment can control the depth of the shaft inserted into the rotor core, thereby expanding the scope of application of the processing equipment.

[0029] Then, the driving motor 5 is started to work. During the working process, the driving motor 5 will drive the second turntable 4 and the first turntable 3 to rotate synchronously. During the rotation of the second turntable 4 in the rotating groove 22, the first placement hole 31 will be driven to move. During the rotation of the first turntable 3, the second placement hole 41 will be driven to move. Under the rotation of the first turntable 3, the first placement hole 31 will enter the heating box 2 and move out, exposing the second placement hole 41 outside the heating box 2. During the top-down movement, the staff will insert the rotor core into the first placement hole 31 to complete the loading process of the rotor core;

[0030] During the loading process of the rotor core, the staff will also control the shaft to be inserted into the second placement hole 41 within the range of the lower half of the bevel ring 6 to complete the loading process of the shaft. The rotation of the drive motor 5 will drive the first turntable 3 and the second turntable 4 to rotate continuously. The first turntable 3 will drive the loaded rotor core along the rotation groove 22 into the heating box 2. The hot oil in the heating box 2 will contact the rotor core to achieve heating and lubrication. The rotor hot oil will transfer heat to the first turntable 3, making the first turntable 3 itself also a heat source. The first turntable 3 will transfer the heat The amount is transferred to the rotor core in the first placement hole 31 to achieve further heating and heat preservation of the rotor core. After the rotor core rotates to the lower limit position along with the first turntable 3, the first turntable 3 will drive the rotor core to start moving upward. During the upward movement of the rotor core, it will be separated from the hot oil liquid surface in the heating box 2, and the excess hot oil inside the rotor core will drip and be collected by the heating box 2. As the rotor core continues to move, the rotor core will be exposed to the heating box 2 along the rotating groove 22. The rotor core exposed to the heating box 2 moves from bottom to top under the rotation of the first turntable 3;

[0031] During this process, the second turntable 4 will drive the rotating shaft in the second placement hole 41 to move. The rotating shaft in the second placement hole 41 corresponds to and is aligned with the rotor core in the first placement hole 31. The end of the rotating shaft away from the first turntable 3 will be squeezed by the bevel ring 6 as the second turntable 4 rotates. The shortest position of the bevel ring 6 from the second turntable 4 is called the limit point. The end of the rotating shaft away from the first turntable 3 moves along the corresponding second placement hole 41 under the squeezing of the bevel ring 6. The rotating shaft will enter the inner side of the first placement hole 31 during the process of axially moving away from the bracket 51. Since the rotor core in the first placement hole 31 is heated and lubricated by hot oil, the rotating shaft can smoothly pass through the inner side of the rotor core under the push of the bevel ring 6, completing the assembly and manufacturing of the rotor core and the rotating shaft; then the first turntable 3 and the second turntable 4 will continue to rotate and pass the limit point on the bevel ring 6, and then the staff will pull out the assembled rotor core and the rotating shaft from the end of the first placement hole 31 away from the second placement hole 41, completing the unloading of the rotor core and the rotating shaft, and then immediately loading a new rotor core and a new rotating shaft;

[0032] No matter whether the assembled rotor core and shaft are being unloaded or a new rotor core and shaft are being loaded, the first turntable 3 and the second turntable 4 do not stop rotating, that is to say, the first turntable 3 will not stop heating and moving the rotor core, and the second turntable 4 will not stop moving the shaft and be pushed by the bevel ring 6, thereby realizing continuous assembly and manufacturing of the rotor core and the shaft, thereby improving the manufacturing efficiency of the current motor rotor; in addition, since the first turntable 3 has a certain temperature, the first turntable 3 can have a certain preheating and heat preservation effect on the rotor core inside the first placement hole 31, thereby suppressing the heat loss of the rotor core after it is removed from the heating box 2, ensuring the thermal expansion effect of the rotor core, and making the insertion of the shaft into the rotor core smoother.

[0033] Embodiment 2: The first placing hole 31 is evenly provided with first clamping grooves 32 on the inner wall; the first clamping block 33 is slidably connected in the first clamping groove 32; the first clamping block 33 is provided with a first guide angle 331 at the end away from the second turntable 4; the first clamping block 33 is connected to the bottom of the first clamping groove 32 by a first spring 34; the second placing hole 41 is evenly provided with second clamping grooves 42 on the inner wall; the second clamping block 43 is slidably connected in the second clamping groove 42; the second clamping block 43 is provided with a second guide angle 431 at the end away from the first turntable 3; the second clamping block 43 is connected to the bottom of the second clamping groove 42 by a second spring 44.

[0034] In this embodiment, a baffle 23 is fixedly connected to the upper surface of the heating box 2; the baffle 23 is in contact with the first turntable 3; and the baffle 23 can shield the edge of the first placement hole 31 from bottom to top.

[0035] The staff will remove and load the rotor core at the end of the first placement hole 31 away from the second placement hole 41. When placing the new rotor core toward the inside of the first placement hole 31, the rotor core will squeeze the first guide angle 331. The first clamping block 33 will overcome the first spring 34 under the pressure of the first guide angle 331 and retract into the first clamping groove 32. After the rotor core passes the first guide angle 331, the rotor core moves to the inside of the first placement hole 31, and the rotor core will be clamped by multiple first clamping blocks 33. The multiple first clamping blocks 33 clamp the rotor core in the center. The multiple first clamping blocks 33 can clamp rotor cores of different specifications.

[0036] Similarly, the staff will load the rotating shaft at the end of the second placement hole 41 away from the first placement hole 31. In the process of inserting the new rotating shaft into the second placement hole 41, the second guide angle 431 will be squeezed. The second guide angle 431 will drive the second clamping block 43 to move during the compression process, so that the second clamping block 43 overcomes the second spring 44 and retracts to the second clamping groove 42. After the rotating shaft passes the second guide angle 431 and moves to the inside of the second placement hole 41, the rotating shaft will be clamped by multiple second clamping blocks 43. Multiple second clamping blocks 43 can clamp the rotating shafts of different outer diameters in the center on the inside of the second placement hole 41 and align them with the rotor core in the first placement hole 31.

[0037] After the first turntable 3 drives the rotor core to pass through the hot oil in the heating box 2 for heating, the shaft is squeezed by the bevel ring 6 as the second turntable 4 rotates. The bevel ring 6 will squeeze the shaft along the second placement hole 41 into the first placement hole 31. A certain resistance will be formed in the process of the shaft entering the inner side of the rotor core inside the first placement hole 31. The resistance will cause the core to move toward the first placement hole 31 away from the opening of the second placement hole 41. The rotor core will be blocked and limited by the baffle 23. As the shaft continues to move, the shaft will smoothly pass through the inner side of the rotor core and cross the baffle 23. After completing the assembly and manufacturing of the rotor core and the shaft, the first turntable 3 will drive the corresponding first placement hole 31 to be staggered with the baffle 23, and then the staff can smoothly remove the assembled rotor core and shaft.

[0038] This embodiment can clamp rotor cores and rotating shafts of different specifications through the cooperation of the first clamping block 33 and the second clamping block 43, and keep the rotor cores and rotating shafts of different specifications aligned after clamping, thereby expanding the use range of the processing equipment.

[0039] Embodiment 3: The first turntable 3 is evenly provided with first rotating holes 35 around the center; the first rotating hole 35 is rotatably connected to the first rotating seat 36; the first placement hole 31 is provided on the first rotating seat 36; the outer wall of the first rotating seat 36 is fixedly connected to the first outer toothed ring 37; the first outer toothed ring 37 partially passes through the first rotating hole 35 and extends to the outside of the first turntable 3; the outer wall of the first turntable 3 is rotatably connected to the first inner toothed ring 38; the first inner toothed ring 38 is fixedly connected to the heating box 2; the first inner toothed ring 38 is meshed with multiple first outer toothed rings 37 for transmission.

[0040] In this embodiment, the second turntable 4 is evenly penetrated by second rotating holes 45 around the center; the second rotating hole 45 is rotatably connected to the second rotating seat 46; the second placement hole 41 is arranged on the second rotating seat 46; the outer wall of the second rotating seat 46 is fixedly connected to the second outer tooth ring 47; the second turntable 4 is provided with an outer tooth groove 48 on the side away from the first turntable 3; the outer tooth groove 48 is connected to the part of the second rotating hole 45 close to the center of the second turntable 4; the third outer tooth ring 49 is rotatably connected to the outer tooth groove 48; the third outer tooth ring 49 is meshed with multiple second outer tooth rings 47 for transmission; the third outer tooth ring 49 is fixedly connected to the outer casing of the driving motor 5.

[0041] During the rotation of the first turntable 3, the first turntable 3 will drive multiple first turntables 36 to move around the center of the first turntable 3. The first outer tooth ring 37 on the outer wall of the first turntable 36 is meshed with the first inner tooth ring 38. Therefore, the first turntable 36 will rotate during the movement around the center of the first turntable 3. During the rotation of the first turntable 36, it will enter the heating box 2. The first turntable 36 can drive the rotor core clamped in the first placement hole 31 to rotate. During the rotation of the rotor core, it will contact the hot oil in the heating box 2, thereby improving the heating uniformity of the rotor core. As the first turntable 3 rotates, the rotating first turntable 36 will move up and break away from the hot oil liquid surface. The first turntable 3 under rotation can drive the rotor core to throw away excess hot oil, thereby avoiding waste of hot oil.

[0042] The rotor core that has been heated and lubricated moves to the outside of the heating box 2 as the first turntable 3 rotates, and then the rotor core is passed through by the shaft under its own rotation. Due to the rotation of the rotor core, the shaft rotates relatively and passes through the inside of the rotor core, thereby facilitating the assembly and manufacturing of the motor rotor. In addition, the second turntable 4 will also rotate during the rotation of the first turntable 3. During the rotation of the second turntable 4, multiple second turntables 46 will be driven to rotate around the center of the second turntable 4. During the revolution of the second turntable 46, the second outer tooth ring 47 will be meshed with the third outer tooth ring 49 in the outer tooth groove 48. In this way, the second turntable 4 will rotate during its revolution. During the rotation of the second turntable 4, the shaft clamped in the second placement hole 41 will rotate. The direction of rotation of the shaft is opposite to the rotation direction of the corresponding rotor core. In this way, the rotation speed of the shaft when inserted into the inside of the rotor core is further enhanced, making it easier for the shaft to pass through the rotor core under rotation, further improving the assembly and manufacturing efficiency of the rotor core and the shaft.

[0043] Embodiment 4: The first turntable 3 divides the heating groove 21 in the heating box 2 into a first heat groove 211 and a second heat groove 212; the first heat groove 211 is located on the side of the first turntable 3 away from the second turntable 4; the first heat groove 211 is movably sealed and connected to a movable plate 24; the movable plate 24 is connected to the groove wall of the first heat groove 211 on the side away from the first turntable 3 through a third spring 25; the movable plate 24 divides the first heat groove 211 into a far disk cavity 213 and a near disk cavity 214; the first turntable 3 is away from the second turntable 4 An annular groove 39 is arranged on the side; a shift block 7 is arranged at the bottom of the annular groove 39; a shift bar 8 is movably connected in the annular groove 39; the shift bar 8 is fixedly connected to the movable plate 24; a transition surface 71 is arranged on the side where the shift block 7 contacts the shift bar 8; a storage cavity 16 is arranged inside the base 1; the storage cavity 16 is connected to the second heat groove 212; the remote disk cavity 213 is connected to the storage cavity 16; a heating plate 17 is arranged in the storage cavity 16; a joint 18 is arranged on the front side of the base 1; the joint 18 is connected to the storage cavity 16.

[0044] During the rotation of the first turntable 3, the rotor core in the first placement hole 31 will be driven to move into the heating groove 21. During the rotation of the first turntable 3, the annular groove 39 and the shifting block 7 at the bottom of the annular groove 39 will be driven to move. The multiple shifting blocks 7 in the annular groove 39 will shift the shifting bar 8 in turn. When the shifting bar 8 is shifted, it will drive the movable plate 24 to move in the first heat groove 211. The movable plate 24 divides the first heat groove 211 into a far disk cavity 213 and a near disk cavity 214. The far disk cavity 213 is away from the first turntable 3. In the process of the shifting bar 8 driving the movable plate 24 away from the first turntable 3, the far disk cavity 213 will become smaller, and the space of the near disk cavity 214 will become larger. The annular groove 39 exposed from the heating box 2 will be blocked and sealed by the sealing plate. In this way, negative pressure will be formed during the expansion of the near disk cavity 214, and the oil in the far disk cavity 213 will enter under the pressure of the movable plate 24. Enter the storage chamber 16, the hot oil in the storage chamber 16 heated by the heating plate 17 will enter the second heat groove 212 under negative pressure and extrusion, and finally enter the near disk cavity 214 along the multiple first placement holes 31, as the shift bar 8 passes over the shift block 7, the third spring 25 will push the movable plate 24 to approach the first turntable 3, so that the far disk cavity 213 expands to form a negative pressure to suck the oil in the storage chamber 16, the hot oil in the near disk cavity 214 will enter the second heat groove 212 along the first placement hole 31, and finally flow back to the storage chamber 16, so that in the process of the hot oil passing back and forth through the rotor core in the first placement hole 31, the rotor core can be quickly heated and lubricated, the preheating efficiency of the rotor core is improved, and the subsequent assembly and manufacturing efficiency of the rotor core and the shaft is further improved; the joint 18 can be opened when the oil in the storage chamber 16 is replenished.
