Description

Technical Field

[0001] The invention relates to the technical field of motor processing, and in particular to a supporting device for processing a motor rotor. Background Art

[0002] In the field of motor manufacturing, the rotor is one of the core components of the motor, and its processing quality and precision are directly related to the overall performance and life of the motor. However, in the existing motor production and processing process, there are often some problems in the rotor processing link, which to a certain extent restrict the development of the motor manufacturing industry.

[0003] First of all, the quality and precision of rotor processing are crucial to the performance of the motor. Factors such as the balance, dimensional accuracy, and surface roughness of the rotor will directly affect the motor's operating efficiency, noise, and vibration. However, in actual production, many motor manufacturers use arbitrary clamping methods during rotor processing and lack unified clamping specifications and standards, which leads to low rotor processing accuracy and cannot meet the high-precision requirements of high-end motor products for rotors.

[0004] Secondly, the lack of specific brackets during rotor processing is also a problem that needs to be solved urgently. The bracket plays a role in fixing and supporting the rotor during rotor processing, which is of great significance for ensuring processing accuracy and improving processing efficiency. However, many motor manufacturers currently do not use specific brackets when processing rotors, but use some simple fixtures or directly place the rotor on the processing table for processing. This method not only fails to guarantee the processing accuracy of the rotor, but also easily causes the rotor to deform or be damaged during the processing process.

[0005] Chinese patent publication number CN117175869B discloses a motor rotor bracket, including a motor rotor, a rotor bracket and a support seat, the rotor bracket is provided with a guide hole and two threaded grooves, two support bearings are fixedly connected inside the rotor bracket, a support mechanism is arranged on the top of the support seat, the support mechanism includes a support frame, a clamping assembly and a pushing assembly, the support frame includes a discharge frame, a clamping block, a pressure sensor and a first pneumatic cylinder.

[0006] During the machining process, the motor rotor often needs to adjust the direction of the machining part so that it faces the working end of the machining machine to achieve the best machining effect. However, the current rotor bracket design cannot be rotated and adjusted after the rotor is fixed by the clamping box. This means that whenever the direction of the machining part of the rotor needs to be changed, the operator must first release the clamping box from the rotor, and then re-clamp the rotor after the rotor rotates to the appropriate position.

[0007] This operation is not only cumbersome but also inefficient. Each release and re-clamping takes a certain amount of time, and improper operation may cause the rotor position to shift, affecting the processing accuracy. In addition, frequent clamping and release operations may also cause certain wear on the clamping box and the rotor itself, further increasing the processing cost. Summary of the invention

[0008] In view of the above problems, a support device for motor rotor processing is provided, in which a clamping wheel in a clamping mechanism on a support moves radially and clamps the end shaft of the motor rotor, and the clamping wheel can be locked by a locking assembly to ensure that when the motor rotor needs to be rotated, the clamping wheel can be unlocked by the locking assembly to accurately rotate the motor rotor, thereby solving the problem that the existing motor rotor bracket cannot rotate in a clamped state.

The clamping wheel can abut against the circumferential surface of the rotor shaft end along the radial direction of the clamping opening. In the clamping state, the clamping wheel can rotate with the rotor. The clamping mechanism also includes a locking component for locking the clamping wheel to prevent it from rotating, and the clamping wheel can move along the radial direction of the clamping opening when locked.

[0010] Preferably, the number of the clamping wheels is 3n (n is a non-zero integer).

[0012] Preferably, the clamping mechanism further comprises a rotation driving assembly for driving the rotating ring to rotate relative to the fixed ring. In a working state, the rotation driving assembly inputs a rotation torque to the rotating ring.

[0013] Preferably, the rotary drive assembly includes an arcuate rack, a spur rack and an elastic shifter. The arcuate rack is coaxially and fixedly arranged on the outer circumferential surface of the rotating ring. The elastic shifter is arranged on a support. The elastic shifter has a working end that can move along the tangential direction of the rotating ring. The spur rack is connected to the working end of the elastic shifter, and the spur rack is meshed with the arcuate rack.

When the locking shaft slides so that the pressure ring abuts against the end of the abutment ring, the abutment ring cannot rotate relative to the mounting shaft.

[0016] Preferably, an elastic reset element is provided between the pressure ring and the end of the clamping wheel.

DETAILED DESCRIPTION

[0033] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, this application provides:

[0035] A support device for machining a motor rotor 1 comprises a support 2, and two clamping mechanisms 3 arranged on the support 2 for fixing the rotor end shaft, the clamping mechanism 3 comprises a clamping opening 31 for the rotor end shaft to pass through, a clamping wheel 32 is distributed in the clamping opening 31 along its circumference, the clamping wheel 32 can abut against the circumferential surface of the rotor shaft end along the radial direction of the clamping opening 31, in the clamping state, the clamping wheel 32 can rotate with the rotor, the clamping mechanism 3 also comprises a locking assembly for locking the clamping wheel 32 to prevent it from rotating, and the clamping wheel 32 can move along the radial direction of the clamping opening 31 in the locked state.

[0036] Herein, “end shaft” refers to the shaft parts at both ends of the motor rotor 1.

[0037] The two clamping mechanisms 3 are movably arranged on the support 2 , and the bottom of the clamping mechanisms 3 can be fixed to the support 2 to adjust the distance between the two clamping mechanisms 3 .

[0038] The support 2 is provided with two supporting plates extending in the longitudinal direction, and the top of the supporting plate is provided with a V-shaped groove. The motor rotor 1 can be placed horizontally in the V-shaped groove to guide the clamping mechanism 3 to move toward the end shaft direction, and the end shaft is inserted into the clamping opening 31 of the clamping mechanism 3. The clamping mechanism 3 is started, so that the clamping wheel 32 in the clamping opening 31 moves radially along the clamping opening 31, and then the clamping wheels 32 distributed circumferentially along the clamping opening 31 can clamp the end shaft radially. In this state, the clamping wheel 32 can rotate, so that the motor rotor 1 clamped by the clamping wheel 32 can rotate, so that the processing part of the motor rotor 1 can face the working end of the processing machine. After the locking assembly is started, the locking assembly locks the clamping wheel 32. In this state, the clamping wheel 32 cannot rotate, and then the clamped motor rotor 1 cannot rotate, thereby ensuring that during the processing, the motor rotor 1 cannot rotate and affect the processing accuracy.

[0039] This embodiment realizes efficient clamping and rotation adjustment of the end shaft of the motor rotor 1 through the clamping mechanism 3 on the support 2. Specifically, the clamping wheel 32 in the clamping mechanism 3 can move radially to accurately clamp the end shaft of the motor rotor 1 to ensure the stability of the rotor during processing. At the same time, the design also introduces a locking component, which can lock the clamping wheel 32 when necessary to prevent unnecessary displacement of the rotor during processing, further improving the processing accuracy.

[0040] When the orientation of the machining part of the rotor needs to be adjusted, the locking assembly plays a vital role. The operator can unlock the clamping wheel 32 through a simple operation. At this time, although the clamping wheel 32 still keeps contact with the rotor end shaft, it no longer applies a locking force to it, so that the rotor can rotate freely. Combining the clamping and rotation functions not only ensures the stability of the rotor, but also realizes the convenience of rotation adjustment.

[0041] During the rotation adjustment process, the operator can accurately control the rotation angle of the rotor to ensure that the processing part is facing the working end of the processing machine. After the adjustment is completed, the locking assembly locks the clamping wheel 32 again to restore the stable clamping state of the rotor. The entire operation process is simple and fast, and there is no need to frequently release and re-clamp the rotor, which greatly improves the processing efficiency.

[0042] like Figure 6 As shown, the clamping wheel 32 has 3n n, where n is a non-zero integer.

[0043] When n=1, that is, the number of clamping wheels 32 is 3, they can be located at three equidistant points of the rotor, forming a stable triangular structure to ensure that the rotor will not shake or deviate during processing. As the value of n increases, the number of clamping wheels 32 also increases accordingly, and the uniformity and stability of clamping will also improve accordingly. However, at the same time, too many clamping wheels 32 will also increase the complexity of operation. Therefore, in practical applications, it is necessary to select a suitable value of n according to the size, shape and processing requirements of the rotor.

[0044] By introducing the design of 3n clamping wheels 32, the rotor bracket can achieve rapid rotation and adjustment of the rotor while ensuring clamping stability. During the processing, the operator can easily rotate the rotor to the required angle by simply operating the locking assembly, which greatly improves the processing efficiency.

[0045] like Figure 4 , Figure 7 and Figure 8As shown, the clamping mechanism 3 includes a fixed ring 341, a rotating ring 342 and a mounting shaft 343. The fixed ring 341 is fixedly arranged on the support 2, and the rotating ring 342 is coaxially rotatably arranged at one end of the fixed ring 341. The fixed ring 341 is provided with a guide groove 3411 extending along its radial direction, and the rotating ring 342 is provided with a guide groove 3421 deviating from its radial direction. The mounting shaft 343 passes through the guide groove 3411 and the guide groove 3421 and slidably cooperates with them, and the clamping wheel 32 is rotatably arranged on the mounting shaft 343.

[0046] The inner openings of the fixed ring 341 and the rotating ring 342 form a clamping opening 31 .

[0047] In order to enable the clamping wheel 32 to move radially along the clamping opening 31, the fixed ring 341 is fixedly arranged on the support 2, and the rotating ring 342 is rotatably arranged at one end of the fixed ring 341, so that when the rotating ring 342 rotates relative to the fixed ring 341, the guide groove 3421 and the guide groove 3411 move alternately, so that the installation shaft 343 passing through the guide groove 3411 and the guide groove 3421 can move radially along the clamping opening 31, thereby enabling the clamping wheel 32 to radially abut against the end shaft of the motor rotor 1.

[0048] like Figure 5 As shown, the clamping mechanism 3 further includes a rotation driving assembly 35 for driving the rotating ring 342 to rotate relative to the fixed ring 341 . In the working state, the rotation driving assembly 35 inputs a rotation torque to the rotating ring 342 .

[0049] When the rotary drive assembly 35 is started, the rotary drive assembly 35 can input torque to the rotating ring 342 , thereby allowing the rotating ring 342 to rotate relative to the fixed ring 341 , thereby guiding the clamping wheel 32 to clamp the end shaft of the motor rotor 1 along the radial direction of the clamping opening 31 .

[0050] like Figure 6 As shown, the rotary drive assembly 35 includes an arcuate rack 351, a spur rack 352 and an elastic shifter. The arcuate rack 351 is coaxially fixedly arranged on the outer circumferential surface of the rotating ring 342. The elastic shifter is arranged on the support 2. The elastic shifter has a working end that can move along the tangential direction of the rotating ring 342. The spur rack 352 is connected to the working end of the elastic shifter, and the spur rack 352 is meshed with the arcuate rack 351.

[0051] The elastic displacer can produce a smooth and controllable displacement. When the elastic displacer is activated, the elastic displacer drives the spur rack 352 to move in the horizontal direction. The spur rack 352 is precisely meshed with the arc rack 351, so the movement of the spur rack 352 is converted into the rotation of the arc rack 351. Since the arc rack 351 is connected to the rotating ring 342, the rotation of the arc rack 351 will eventually drive the rotating ring 342 to rotate relative to the fixed ring 341.

[0052] In the process of the clamping wheel 32 clamping the end shaft of the motor rotor 1, since the working end of the elastic displacer uses elastic material to guide the movement of the spur rack 352, the elastic displacer can prevent the clamping wheel 32 from directly reacting the rigid force of the end shaft to the elastic displacer, thereby effectively protecting the elastic displacer from damage. Secondly, this elastic guiding method can buffer the force generated during the clamping process and prevent instantaneous impact from causing damage to the motor rotor 1 and the clamping mechanism 3. Finally, by buffering the force, the clamping wheel 32 can more effectively apply the clamping force to ensure the stability and accuracy of the motor rotor 1 during the processing.

[0053] like Figure 6 As shown, the elastic shifter includes a screw rod 353, a threaded sleeve 354, a connecting block 355, an elastic compression element 356 and a motor 357. The screw rod 353 is rotatably arranged on the support 2, the threaded sleeve 354 is sleeved on the screw rod 353 and is threadedly connected thereto, the connecting block 355 is slidably arranged on the support 2 and is connected to the spur rack 352, the threaded sleeve 354 passes through the connecting block 355 and is slidably engaged therewith, limit rings 3541 are arranged at both ends of the threaded sleeve 354, the elastic compression element 356 is arranged between the sliding block and the limit ring 3541, and the output shaft of the motor 357 is transmission-connected to the screw rod 353.

[0054] When the motor 357 is started, the output shaft of the motor 357 drives the screw rod 353 to rotate, and the screw rod 353 passes through the threaded sleeve 354 and is threadedly connected thereto, and the threaded sleeve 354 passes through the connecting block 355 and is engaged and slidably matched, so that when the screw rod 353 rotates, the threaded sleeve 354 compresses the elastic compression element 356 and drives the connecting block 355 to move horizontally, and the connecting block 355 drives the spur rack 352 to slide and drives the arc rack 351 meshing with the spur rack 352 to rotate, and at the same time the elastic compression element 356 can buffer the rigid force.

[0055] like Figure 4 and Fig. 9As shown, the locking assembly includes a locking shaft 331 which coaxially passes through the mounting shaft 343. The locking shaft 331 and the mounting shaft 343 are slidably connected with each other. A pressure ring 332 coaxial with the locking shaft 331 is provided at one end of the locking shaft 331, and a synchronous shifter is provided at the other end of the locking shaft 331. When the locking shaft 331 slides so that the pressure ring 332 abuts against the end of the abutment ring, the abutment ring cannot rotate relative to the mounting shaft 343.

[0056] When it is necessary to lock the clamping wheel 32, start the synchronous toggle switch to make all the locking shafts 331 slide in the mounting shaft 343, and make the pressure ring 332 at one end of the locking shaft 331 abut against one end of the clamping wheel 32, and the locking shaft 331 and the mounting shaft 343 are engaged and slidably connected, so that the clamping wheel 32 cannot rotate relative to the mounting shaft 343 due to the static friction force at one end of the clamping wheel 32, so that the clamping wheel 32 cannot rotate when the clamping end shaft is clamped, thereby locking the clamping wheel 32.

[0057] like Figure 4 As shown, an elastic reset element 336 is provided between the pressure ring 332 and the end of the clamping wheel 32 .

[0058] An elastic reset element 336 is provided between the pressure ring 332 and the clamping wheel 32, so that after the synchronous actuator is reset, the pressure ring 332 is moved away from the end of the clamping wheel 32 under the elastic force of the elastic reset element 336, so that the clamping wheel 32 can rotate to facilitate the rotation of the motor rotor 1.

[0059] like Figure 4 As shown, the synchronous toggle switch includes a fixed threaded cylinder 333 coaxially fixed at one end of a fixed ring 341, an adjusting threaded cylinder 334 threadedly connected to the fixed threaded cylinder 333, and a toggle ring 335 slidably arranged at one end of the fixed ring 341, the toggle ring 335 abuts against the inner end of the adjusting threaded cylinder 334, the toggle ring 335 is provided with an avoidance groove 3351 extending along its radial direction, the locking shaft 331 slides through the avoidance groove 3351, and one end of the locking shaft 331 is provided with a connector 337 abutting against the toggle ring 335.

[0060] When the adjusting threaded cylinder 334 is rotated relative to the fixed threaded cylinder 333, the adjusting threaded cylinder 334 drives the toggle ring 335 to move in the axial direction relative to the fixed ring 341, and the toggle ring 335 is provided with an avoidance groove 3351 distributed along its circumference, and a connector 337 is provided at one end of the locking shaft 331, and the connector 337 abuts against one end of the toggle ring 335. Under the action of the elastic reset element 336, the connector 337 elastically abuts against one end of the toggle ring 335, and the movement of the toggle ring 335 can drive all the locking shafts 331 to move in the installation shaft 343, so as to guide the pressure ring 332 to abut against the end of the clamping wheel 32, thereby locking the clamping wheel 32.

[0061] like Fig. 9 As shown, the connector 337 includes a connection seat 3371 fixedly arranged at the end of the locking shaft 331 , and a ball 3372 is arranged at one end of the connection seat 3371 facing the toggle ring 335 , and the ball 3372 abuts against the toggle ring 335 .

[0062] The connecting seat 3371 is connected to one end of the locking shaft 331 , and the ball 3372 is disposed between the connecting seat 3371 and the toggle ring 335 , thereby effectively reducing the friction between the connecting seat 3371 and the toggle ring 335 .

[0063] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
