Description

Technical Field

[0001] The invention relates to the technical field of rotor turning, and in particular to a motor rotor machining device and process. Background Art

[0002] ABS motor, or anti-lock braking system motor, is a motor used in automobile braking systems, usually a DC motor. The rotor is the rotating part of the motor, which is mainly used to realize the conversion of electrical energy into mechanical energy. During the rotor manufacturing process, the converter on the integrated rotor needs to be fine-machined to meet production requirements. When the converter on the integrated rotor is fine-machined by existing equipment, it is usually placed in the V-groove on the lathe, and then the synchronous belt located above the V-groove is lowered to the top of the rotor through the lifting device and pressed. The synchronous belt drives the rotor to rotate at high speed, and the rotor converter is turned using a lathe.

[0003] For example, in the Chinese patent with the authorization announcement number CN113477951B and the name of the rotor finishing processing device, the operator places the rotor part in the V-groove of the sliding frame, and the pressure roller drives the clamping belt to run. The clamping belt squeezes the rotor downward to position the rotor. At the same time, the clamping belt drives the rotor to rotate through friction, and then the turning tool feeds to turn the rotor. The turned rotor is transported to the next workstation.

[0004] With regard to the above-mentioned related technologies, the chips removed by the rotor will be retained in the V-groove, and the rotor will contact the chips in the V-groove when rotating, causing wear. In addition, since the clamping belt is a soft material that can be stretched, the upward vibration of the rotor when being cut will stretch the clamping belt, so that the clamping belt is difficult to limit the vibration of the rotor in the vertical direction. The contact between the chips in the V-groove and the rotor will increase the amplitude of the rotor's up and down rotation, thereby reducing the rotor's cutting accuracy. Summary of the invention

[0005] In view of this, the present invention provides a motor rotor processing device and process, aiming to solve the problem that the rotor will contact with the chips in the V-groove during rotation, causing wear, and the contact between the chips and the rotor will increase the amplitude of the rotor's up and down rotation, thereby reducing the rotor cutting accuracy.

[0006] To solve the above technical problems, in the first aspect, the present invention provides a motor rotor processing device, including a frame, a supporting frame, a pressure belt, a driving mechanism for driving the pressure belt to run, and a cutting knife; the frame is connected with a rotating shaft and a first rotating source for driving the rotating shaft to rotate, the outer side surface of the rotating shaft is fixedly connected with a plurality of fixed blocks in the circumferential direction, a transmission rack and a driven rack are slidably connected inside the fixed block, a transmission gear is meshed between the transmission rack and the driven rack, the transmission gear is fixedly connected with a limiting block, and the rotor is placed between the fixed block and the limiting block; the frame is fixedly connected with a first linear drive, the driving shaft of the first linear drive is fixedly connected with a sliding frame, the outer side surface of the sliding frame is fixedly connected with a transmission rod and an unlocking rod, the transmission rod is used to push the transmission rack to move, and when the rotor rotates downward with the fixed block, the unlocking rod pushes the driven rack to move.

In addition, during the machining of the rotor, the fixed block rotates around the rotation axis, so that when the V-shaped groove of the fixed block rotates downward, the chips in the fixed block are separated from the fixed block by their own gravity, reducing the friction between the rotor and the chips in the fixed block, while further reducing the amplitude of the up and down vibration of the rotor, and improving the machining accuracy of the rotor.

The locking block is fixedly connected with a return spring, and the return spring is fixedly connected to the transmission rack and the driven rack at one end away from the locking block.

[0011] By adopting the above technical solution, the reset spring pushes the locking block into the locking groove, thereby locking the transmission rack to prevent the transmission rack from freely rotating and driving the limit block to separate from the rotor during the processing of the rotor, thereby improving the reliability of the limit block locking the rotor position.

[0012] Optionally, the fixed block consists of a first block and a second block, the first block and the second block are arranged on both sides of the rotor along the axial direction of the rotor, the first block is arranged away from the sliding frame, the upper surface of the first block is fixedly connected to a limiting part, the outer side surface of the sliding frame is fixedly connected to a limiting rod, and the rotor is located between the limiting part and the limiting rod.

[0014] Optionally, the fixed block is divided into a loading block, a processing block and a loading block along the circumference of the rotating shaft.

[0015] Optionally, the support frame is slidably connected to the frame, and a second linear drive is fixedly connected between the support frame and the frame.

At this time, the rotor falls down and disengages from the fixed block due to its own gravity for unloading.

[0021] By adopting the above technical solution, the loading block, the processing block and the unloading block rotate continuously around the rotating shaft, so that the loading and unloading can be carried out while the rotor is being cut, thereby improving the processing efficiency of the rotor.

[0022] In summary, compared with the prior art, the present invention includes at least one of the following beneficial technical effects: 1. The limit block and the fixed block cooperate to lock the position of the rotor, replacing the compression belt to lock the position of the rotor, and using a rigid structure instead of a flexible structure to lock the position of the rotor, reducing the amplitude of the up and down vibration of the rotor during cutting. In addition, during the machining of the rotor, the fixed block rotates around the rotating axis, so that when the V-shaped groove of the fixed block rotates downward, the chips in the fixed block are separated from the fixed block by their own gravity, reducing the friction between the rotor and the chips in the fixed block, while further reducing the amplitude of the up and down vibration of the rotor, and improving the machining accuracy of the rotor.

[0023] 2. In the process of rotating the rotor upward to the processing block, the device does not need to move the clamping belt in the vertical direction to avoid the rotor. That is, when the rotor rotates upward to the processing block, the clamping belt abuts against the rotor, which reduces the time when the rotor is not processed during the process of the clamping belt avoiding the rotor, and further improves the processing efficiency of the rotor.

[0026] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be combined with the embodiments of the present invention. Figure 1-Figure 6 , the technical scheme of the embodiment of the present invention is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0027] This embodiment provides a motor rotor processing device, referring to Figure 1 and Figure 2 A motor rotor processing device includes a frame 1, a support frame 11, a clamping belt 12, a driving mechanism 2, a cutting tool 13 for turning a rotor 8, a limiting mechanism for limiting the rotor 8, and an unlocking mechanism for driving the rotor 8 to disengage from the positioning mechanism.

[0028] Reference Figure 1 and Figure 2 The frame 1 is erected on a horizontal plane, the support frame 11 is connected to the upper end of the frame 1, the compression belt 12 is arranged on one side of the support frame 11, and the driving mechanism 2 is fixedly connected to the support frame 11. The driving mechanism 2 is used to support the compression belt 12 and drive the compression belt 12 to run, so that the compression belt 12 can drive the rotor 8 to rotate.

[0029] Reference Figure 2 , Figure 3 and Figure 4The positioning mechanism includes a rotating shaft 3, a first rotating source 31, a driving gear 311, a driven gear 32, a fixing block 4, a transmission rack 5, a driven rack 51, a transmission gear 52 and a stop block 53. The first rotating source 31 is fixedly connected to the frame 1, the driving gear 311 is fixedly sleeved on the outer side of the driving shaft of the first rotating source 31, the rotating shaft 3 is rotatably connected to the frame 1, the driven gear 32 is fixedly sleeved on the outer side of the rotating shaft 3, and the driven gear 32 can mesh with the driving gear 311. Therefore, the first rotating source 31 drives the rotating shaft 3 to rotate through the driving gear 311 and the driven gear 32.

[0030] Reference Figure 2 , Figure 3 and Figure 4 , six fixed blocks 4 are provided and fixedly connected to the outer side of the rotating shaft 3, the fixed blocks 4 are evenly distributed on both sides of the rotating shaft 3 along the axial direction of the rotating shaft 3, and the fixed blocks 4 are arrayed on the outer side of the fixed blocks 4 along the circumferential direction. Specifically, the fixed blocks 4 are V-shaped blocks, and a receiving cavity 47 is provided inside the fixed blocks 4. The fixed blocks 4 are divided into a loading block 44, a processing block 45 and a unloading block 46 along the circumferential direction of the rotating shaft 3. There are twelve transmission racks 5, driven racks 51, transmission gears 52 and limit blocks 53, and every two transmission racks 5, driven racks 51, transmission gears 52 and limit blocks 53 correspond to one fixed block 4. The transmission rack 5 and the driven rack 51 are horizontally slidably arranged in the accommodating cavity 47, the transmission rack 5 and the driven rack 51 are arranged opposite to each other, the transmission gear 52 is rotatably connected inside the accommodating cavity 47, the transmission gear 52 is located between the transmission rack 5 and the driven rack 51, and the transmission rack 5 and the driven rack 51 are both meshed with the transmission gear 52. The limit block 53 is coaxially fixedly connected with the transmission gear 52, the limit block 53 is located outside the fixed block 4, and the rotor 8 is located between the fixed block 4 and the two limit blocks 53 connected to the fixed block 4.

[0031] Reference Figure 4 The unlocking mechanism includes a first linear actuator 6, a sliding frame 61, a transmission rod 62 and an unlocking rod 63. The first linear actuator 6 is fixedly connected to the upper surface of the frame 1, the sliding frame 61 is fixedly connected to the driving shaft of the first linear actuator 6, the transmission rod 62 and the unlocking rod 63 are fixedly connected to the side of the sliding frame 61 close to the support frame 11, the transmission rod 62 and the unlocking rod 63 are arranged at both ends of the sliding frame 61, the transmission rod 62 is arranged corresponding to the upper material block 44, the transmission rod 62 can push the transmission rack 5 to move, the unlocking rod 63 is arranged corresponding to the lower material block 46, and the unlocking rod 63 can push the driven rack 51 to move.

[0032] The operator places the rotor 8 to be processed on the surface of the loading block 44, and the first linear actuator 6 drives the transmission rod 62 to move into the accommodating cavity 47 through the sliding frame 61. The transmission rod 62 pushes the transmission rack 5 in the loading block 44 to move toward the inside of the upper block 44, and the transmission rack 5 drives the limit block 53 to rotate through the transmission gear 52, so that the limit block 53 cooperates with the loading block 44 to lock the rotor 8, and at the same time, the transmission gear 52 drives the driven rack 51 to move to the outside of the upper block 44.

[0033] The first rotation source 31 drives the rotating shaft 3 to rotate, so that the rotor 8 in the loading block 44 rotates upward to the processing block 45. When the rotor 8 rotates to the top, it contacts the pressing belt 12. The belt drives the rotor 8 to rotate, and the cutting tool 13 performs turning processing on the rotor 8. After the processing is completed, the rotating shaft 3 drives the rotor 8 to rotate downward to the unloading block 46. The first linear actuator 6 drives the unlocking rod 63 to move into the accommodating chamber 47 through the sliding frame 61. The unlocking rod 63 pushes the driven rack 51 to move. The driven rack 51 drives the limit block 53 to reverse and disengage from the rotor 8 through the transmission gear 52. At this time, the rotor 8 falls off the fixed block 4 by its own gravity to unload.

[0034] The limit block 53 cooperates with the fixed block 4 to lock the position of the rotor 8, replacing the compression belt 12 to lock the position of the rotor 8, and uses a rigid structure instead of a flexible structure to lock the position of the rotor 8, thereby reducing the amplitude of the up and down vibration of the rotor 8 during cutting. In addition, during the processing of the rotor 8, the fixed block 4 rotates around the rotating shaft 3, so that when the V-shaped groove of the fixed block 4 rotates downward, the chips in the fixed block 4 are separated from the fixed block 4 by their own gravity, which reduces the friction between the rotor 8 and the chips in the fixed block 4, further reduces the amplitude of the up and down vibration of the rotor 8, and improves the processing accuracy of the rotor 8.

[0035] Since the transmission rod 62 and the unlocking rod 63 are fixedly connected by the sliding frame 61, the transmission rod 62 and the unlocking rod 63 move synchronously, so that the loading process of the rotor 8 at the loading block 44, the processing process of the rotor 8 at the processing block 45 and the unloading process of the rotor 8 at the unloading block 46 can be carried out simultaneously, thereby improving the processing efficiency of the rotor 8. In addition, the conventional clamping belt 12 needs to move upward to avoid the rotor 8 before placing the rotor 8 on the fixed block 4, and then move the clamping belt 12 downward to abut against the rotor 8, and the rotor 8 is not processed when the clamping belt 12 moves in the vertical direction. In the process of rotating the rotor 8 upward to the processing block 45, the device does not need to move the clamping belt 12 in the vertical direction to avoid the rotor 8, that is, when the rotor 8 rotates upward to the processing block 45, the clamping belt 12 abuts against the rotor 8, which reduces the time when the rotor 8 is not processed during the process of the clamping belt 12 avoiding the rotor 8, further improving the processing efficiency of the rotor 8.

[0036] Reference Figure 1and Figure 5 The driving mechanism 2 includes a second rotation source 21, a driving wheel 22 and a supporting wheel 23. The second rotation source 21 is fixedly connected to the upper surface of the supporting frame 11. The driving wheel 22 is fixedly sleeved on the driving shaft of the second rotation source 21. The supporting wheel 23 is rotatably connected to the supporting frame 11. The compression belt 12 is sleeved on the outer side surfaces of the driving wheel 22 and the supporting wheel 23. The second rotation source 21 drives the driving wheel 22 to rotate, thereby driving the compression belt 12 to run.

[0037] Reference Figure 6 A locking groove 41 is provided on the inner side of the accommodating cavity 47, and the transmission rack 5 and the driven rack 51 are both slidably connected with a locking block 54. The locking groove 41 and the locking block 54 are both spherical, and the locking block 54 can engage with the locking groove 41. The locking block 54 is fixedly connected with a return spring 55, and the end of the return spring 55 away from the locking block 54 is fixedly connected to the transmission rack 5 and the driven rack 51 respectively.

[0038] When the transmission rod 62 pushes the transmission rack 5 in the loading block 44 so that the transmission rack 5 drives the limit block 53 to abut against the rotor 8, the locking block 54 moves synchronously with the transmission rack 5 close to the locking groove 41, and the return spring 55 pushes the locking block 54 into the locking groove 41, thereby locking the transmission rack 5 to prevent the transmission rack 5 from freely rotating and driving the limit block 53 to separate from the rotor 8 during the processing of the rotor 8, thereby improving the reliability of the limit block 53 locking the position of the rotor 8.

[0039] When the rotor 8 is located at the unloading block 46, the unlocking rod 63 pushes the driven rack 51 in the unloading block 46 to move. Since the locking groove 41 and the locking block 54 are both spherical, the locking block 54 moves with the driven rack 51 to disengage from the locking groove 41, and the return spring 55 is compressed.

[0040] Reference Figure 4 The fixed block 4 is composed of a first block 42 and a second block 43. The first block 42 and the second block 43 are arranged on both sides of the rotor 8 along the axial direction of the rotor 8. The first block 42 is arranged away from the sliding frame 61. The upper surface of the first block 42 is fixedly connected to the limiting portion 421. The outer side surface of the sliding frame 61 is fixedly connected to the limiting rod 611. The rotor 8 is located between the limiting portion 421 and the limiting rod 611. The limiting rod 611 is arranged corresponding to the processing block 45. When the first linear actuator 6 drives the transmission rod 62 and the unlocking rod 63 to move through the sliding frame 61 to load and unload the rotor 8, the limiting rod 611 moves synchronously with the sliding frame 61 to push the rotor 8 to move along the axial direction of the rotating shaft 3, so that the rotor 8 abuts against the limiting portion 421, thereby adjusting the position of the rotor 8 relative to the fixed block 4 and improving the cutting accuracy of the rotor 8.

[0041] Reference Figure 1 and Figure 5The support frame 11 is slidably connected to the frame 1, and a second linear actuator 14 is fixedly connected between the support frame 11 and the frame 1. The second linear actuator 14 drives the support frame 11 to move in the vertical direction, adjusts the position of the compression belt 12 relative to the rotor 8, and enables the compression belt 12 to adapt to rotors 8 of different diameters.

[0042] Reference Figure 1 and Figure 5 , the frame 1 is provided with a transmission mechanism 7 for driving the cutting blade 13 to approach the rotor 8. The transmission mechanism 7 includes a third rotation source 71, a first screw rod 72, a connecting frame 73, a fourth rotation source 74, a second screw rod 75 and a cutting frame 76. The third rotation source 71 is fixedly connected to the frame 1, the first screw rod 72 is fixedly connected to the driving shaft of the third rotation source 71, the connecting frame 73 is slidably connected to the frame 1, and the connecting frame 73 is threadedly connected to the first screw rod 72. The fourth rotation source 74 is fixedly connected to the upper surface of the connecting frame 73, the second screw rod 75 is fixedly connected to the fourth rotation source 74, the cutting frame 76 is slidably connected to the connecting frame 73, the cutting frame 76 is threadedly connected to the second screw rod 75, the cutting blade 13 is fixedly connected to the cutting frame 76, and the first screw rod 72 and the second screw rod 75 are perpendicular to each other.

[0043] The third rotation source 71, the first screw rod 72 and the connecting frame 73 form a screw slider structure, and the third rotation source 71 drives the connecting frame 73 to move through the first screw rod 72. The fourth rotation source 74, the second screw rod 75 and the cutting frame 76 form another screw slider structure, and the fourth rotation source 74 drives the cutting frame 76 to move through the second screw rod 75. Since the first screw rod 72 and the second screw rod 75 are perpendicular to each other, the third rotation source 71 and the fourth rotation source 74 start to drive the cutting frame 76 to move in the horizontal direction, and the cutting knife 13 moves synchronously with the cutting frame 76 to adjust the position of the cutting knife 13 relative to the rotor 8, thereby realizing the process steps of feeding, cutting and retracting the cutting knife 13 to the rotor 8.

[0044] The third rotation source 71 and the fourth rotation source 74 can be electric motors or pneumatic motors, etc. In addition, the transmission mechanism 7 can use linear motors instead of the third rotation source 71 and the fourth rotation source 74 to drive the cutting frame 76 to move. When the third rotation source 71 and the fourth rotation source 74 use a screw slider structure to drive the cutting frame 76 to move a distance equal to that of the linear motor, the third rotation source 71 and the fourth rotation source 74 occupy less space than the linear motor.

[0045] The implementation principle of a motor rotor processing device according to an embodiment of the present invention is as follows: the operator places the rotor 8 to be processed on the surface of the loading block 44, the first linear actuator 6 drives the transmission rod 62 through the sliding frame 61 to push the transmission rack 5 in the loading block 44 to move, the transmission rack 5 drives the limit block 53 to rotate through the transmission gear 52, so that the limit block 53 cooperates with the loading block 44 to lock the rotor 8. The first rotation source 31 rotates the rotor 8 in the loading block 44 to the processing block 45 through the rotating shaft 3, the rotor 8 rotates upward and abuts against the pressing belt 12, the pressing belt 12 drives the rotor 8 to rotate, and the cutting tool 13 performs turning processing on the rotor 8. After the processing is completed, the first rotation source 31 drives the rotor 8 to rotate downward to the unloading block 46 through the rotating shaft 3, the first linear actuator 6 drives the unlocking rod 63 through the sliding frame 61 to push the driven rack 51, the driven rack 51 drives the limit block 53 to reverse and disengage from the rotor 8 through the transmission gear 52, and at this time, the rotor 8 falls off the fixed block 4 by its own gravity to unload.

[0046] In a second aspect, an embodiment of the present invention provides a motor rotor processing technology, which is applied to a motor rotor processing device in the first aspect, and the processing technology is: S1, the operator places the rotor 8 on the surface of the loading block 44, the first linear actuator 6 drives the transmission rod 62 through the sliding frame 61 to push the transmission rack 5 in the loading block 44 to move, and the transmission rack 5 drives the limit block 53 to rotate through the transmission gear 52, so that the limit block 53 cooperates with the loading block 44 to lock the rotor 8; S2, the first rotation source 31 rotates the rotor 8 in the loading block 44 to the processing block 45 through the rotating shaft 3, the rotor 8 rotates upward and abuts against the pressing belt 12, the pressing belt 12 drives the rotor 8 to rotate, and the cutting tool 13 performs turning processing on the rotor 8; S3, after the processing is completed, the first rotation source 31 drives the rotor 8 to rotate downward to the unloading block 46 through the rotating shaft 3, and the first linear drive 6 drives the unlocking rod 63 through the sliding frame 61 to push the driven rack 51, and the driven rack 51 drives the limit block 53 to reverse and disengage from the rotor 8 through the transmission gear 52. At this time, the rotor 8 falls off the fixed block 4 due to its own gravity for unloading.

[0047] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components.
