Technical Field

[0001] This utility model relates to the technical field of rotor grinding equipment, and in particular to a motor rotor grinding equipment. Background Technology

[0002] The motor rotor is the rotating part of the motor, responsible for converting electrical energy into mechanical energy. When machining the rotor, it needs to be ground to improve the surface quality and dimensional accuracy of the motor rotor.

[0003] For example, CN215788748U discloses a grinding equipment for producing motor rotors, including a worktable, a support frame fixed on the top of the worktable, a bidirectional screw rotatably connected inside the support frame, two grinding blocks threaded on the outside of the bidirectional screw, a first unidirectional gear fixed on the left end of the bidirectional screw, and fixed cylinders rotatably connected inside both sides of the support frame, with tightening bolts threaded on the top of each fixed cylinder.

[0004] However, in the existing technology, during the grinding process of the motor rotor, due to the small size of the rotor, there is a problem of difficulty in fixing it. Furthermore, during the grinding process, it is necessary to ensure sufficient contact force between the rotor and the grinding tool, but the rotor is not easy to fix. Therefore, in actual operation, the rotor cannot maintain stable contact with the grinding tool for a long time, and when the contact force is too large, it will directly affect the stability of the rotor. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that the rotor is small in size and therefore difficult to fix during the grinding process, and to propose a motor rotor grinding device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a motor rotor grinding device, comprising an operating table and a spindle box, wherein the spindle box is fixedly installed at one end of the operating table, a first movable table is slidably connected to the upper surface of the operating table, a second movable table is fixedly installed on the top of the operating table, the second movable table is located between the spindle box and the second movable table, a support frame is fixedly installed on the top of the first movable table, and a clamping rod is symmetrically rotatably installed on the top of the support frame, and a blocking block is slidably connected to one end of the top of the second movable table, the blocking block and the spindle box being located on the same axis.

[0007] Preferably, a control lever is rotatably mounted inside the second movable platform, and the control lever is threadedly connected to the blocking block.

[0008] Preferably, a limit ring is fixedly installed on the outer wall of the control rod, and the limit ring is rotatably connected to the second movable platform.

[0009] Preferably, a limit block is fixedly installed inside the first movable platform, and a servo motor is fixedly installed between the two limit blocks.

[0010] Preferably, one end of the clamping rod is rotatably connected to a first rotating rod, the first rotating rod is rotatably installed inside the support frame, and one end of the first rotating rod is fixedly connected to a sector-shaped worm gear.

[0011] Preferably, the output shaft of the servo motor is fixedly connected to a worm gear, which meshes with a sector worm wheel.

[0012] Preferably, a second rotating rod is rotatably mounted at the corner of the top of the support frame, and the other end of the second rotating rod is rotatably connected to the corner of the clamping rod.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, a clamping rod is set on the first movable platform and a blocking rod is set on the second movable platform. During the actual processing, the clamping rod is used to clamp the rotor to prevent the rotor from swaying left and right. During the grinding process, the blocking block can hold the rotor in place to ensure the contact force between the rotor and the grinding tool and prevent the rotor from sliding back and forth. When used together, the stability of the rotor can be ensured during the grinding process, and the rotor can be stably pressed on the grinding tool.

[0015] 2. In this utility model, the stability of the clamping rod is improved by setting a first rotating rod and a second rotating rod. At the same time, the transmission structure of the worm and the sector worm wheel has a self-locking function. During the clamping of the rotor, the clamping rod will not rotate, thereby ensuring that the clamping force will not change. Attached Figure Description

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this utility model provides a motor rotor grinding equipment, including an operating table 1 and a spindle box 4. The spindle box 4 is fixedly installed at one end of the operating table 1. A first movable table 2 is slidably connected to the upper surface of the operating table 1. A second movable table 3 is fixedly installed on the top of the operating table 1. The second movable table 3 is located between the spindle box 4 and the second movable table 3. A support frame 6 is fixedly installed on the top of the first movable table 2. A clamping rod 7 is symmetrically rotatably installed on the top of the support frame 6. A blocking block 5 is slidably connected to one end of the top of the second movable table 3. The blocking block 5 and the spindle box 4 are located on the same axis.

[0025] A control rod 14 is rotatably installed inside the second movable platform 3. The control rod 14 is threadedly connected to the blocking block 5. A limit ring 15 is fixedly installed on the outer wall of the control rod 14. The limit ring 15 is rotatably connected to the second movable platform 3.

[0026] The specific settings and functions of this embodiment are described below. The spindle box 4 is installed at the end of the operating table 1. When in use, the rotor to be processed is clamped by the clamping rod 7. Then the control rod 14 is rotated. The blocking block 5 is threadedly connected to the control rod 14 and a protruding strip is provided at the junction with the second movable table 3. During the rotation of the control rod 14, the blocking block 5 will be pushed out of the second movable table 3. The protruding strip can prevent the blocking block 5 from rotating, while the limiting ring 15 can prevent the control rod 14 from being driven by the blocking block 5.

[0027] When the blocking block 5 contacts the rotor, it will directly push the entire first movable table 2 to move along the direction of the operating table 1 to ensure that the first movable table 2 will not affect the movement of the rotor. After the blocking block 5 pushes the rotor to contact the grinding wheel on the side of the spindle box 4, the spindle box 4 drives the grinding wheel to grind the rotor. The clamping rod 7 is rotatably installed in the support frame 6 to ensure its own structural stability.

[0028] Example 2: Figure 2 , Figure 3 and Figure 4 As shown, a limit block 10 is fixedly installed inside the first movable platform 2, and a servo motor 11 is fixedly installed between the two limit blocks 10. One end of the clamping rod 7 is rotatably connected to a first rotating rod 9, which is rotatably installed inside the support frame 6. One end of the first rotating rod 9 is fixedly connected to a sector worm gear 13, and the output shaft of the servo motor 11 is fixedly connected to a worm 12. The worm 12 meshes with the sector worm gear 13. A second rotating rod 8 is rotatably installed at the corner of the top of the support frame 6, and the other end of the second rotating rod 8 is rotatably connected to the corner of the clamping rod 7.

[0029] The overall effect of this embodiment is that the worm gear 12 and the sector worm wheel 13 are meshed and connected. When the rotor is clamped by the clamping rod 7, the servo motor 11 drives the worm gear 12 to push the sector worm wheel 13, thereby driving the first rotating rod 9. The first rotating rod 9 then drives the clamping rod 7. One end of the second rotating rod 8 inside the clamping rod 7 is rotatably connected to the top of the support frame 6, and the second rotating rod 8 is parallel to the first rotating rod 9. During the rotation of the clamping rod 7, the second rotating rod 8 will help determine the angle of the clamping rod 7 to ensure that the angle of the clamping rod 7 will not be changed. Furthermore, the transmission structure composed of the worm gear 12 and the sector worm wheel 13 has a self-locking function, which can ensure that the clamping force will not change during the clamping of the rotor.

[0030] The usage and working principle of this device are as follows: When in use, the rotor is placed between the two clamping rods 7, and then the servo motor 11 is started. The servo motor 11 drives the first rotating rod 9 by meshing the worm gear 12 with the sector worm wheel 13. The first rotating rod 9 drives the clamping rod 7 to clamp the rotor to be processed. During this process, the second rotating rod 8 can determine the angle of the clamping rod 7 to prevent the angle of the clamping rod 7 from changing.

[0031] After the rotor is fixed, rotate the control lever 14. Since the blocking block 5 is threadedly connected to the control lever 14 and has a protruding strip at the junction with the second movable table 3, the control lever 14 will push the blocking block 5 out of the second movable table 3 during rotation, pushing the rotor to contact the grinding wheel on the side of the spindle box 4. The spindle box 4 drives the grinding wheel to perform grinding on the rotor.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
