Description

Technical Field

[0001] This application relates to the field of motor processing technology, and in particular to a rotor outer cylindrical grinding device. Background Technology

[0002] Rotary electric machines mainly consist of a rotor and a stator. The windings on the stator generate a stationary magnetic field through the current, which interacts with the rotating magnetic field of the rotor to produce an electromagnetic force, thereby driving the rotor to rotate.

[0003] In the existing technology, the outer diameter of the rotor is machined using a lathe. However, many burrs remain on the surface of the machined rotor. Therefore, the rotor after lathe machining still needs to be polished with a grinding wheel. The grinding wheel is usually mounted inside a housing, and there are two grinding wheels. The grinding wheel is driven to rotate by a motor, and two pressure rollers are located above the grinding wheel. The workpiece is placed between the pressure rollers and the grinding wheel. The pressure rollers apply force to the grinding wheel through the workpiece. The pressure rollers are driven to rotate by a motor, and the rotation direction of the pressure rollers is opposite to that of the grinding wheel, thereby polishing the workpiece. During the grinding process of the grinding wheel rotating on the rotor surface, a lot of polishing waste is generated. Workers need to frequently open the cabinet door of the housing to clean up the polishing waste, which is quite inconvenient. Utility Model Content

[0004] The purpose of this application is to address the aforementioned problems in the prior art by proposing a rotor outer cylindrical grinding device.

[0005] This application can be achieved through the following technical solution: a rotor external cylindrical grinding device, including a box with an opening on one side, two grinding wheels that can contact the workpiece are provided inside the box, the grinding wheels are driven to rotate by a grinding wheel motor, two pressure rollers that can contact the workpiece are also provided inside the box, the two pressure rollers are located on the side of the grinding wheel away from the ground and can rotate, the workpiece is placed between the two pressure rollers and the two grinding wheels, and a push plate is provided inside the box and on the side of the grinding wheel close to the ground, the push plate is driven to slide linearly by a driving component to push the waste chips out of the box.

[0006] In the above technical solution, when it is necessary to clean the waste inside the box, the drive component can drive the push plate to move linearly against the inner wall of the box near the ground, thereby pushing the waste out of the box from the opening of the box.

[0007] Furthermore, a door is hinged to one end of the box body near its opening. The projection of the door on the vertical plane can cover the projections of two grinding wheels on the same vertical plane. The bottom surface of the door is located above the inner wall of the box body near the ground, so that waste can leave the box body. The door is fixed in position relative to the box body by a fixing component.

[0008] In the above technical solution, by setting a box door, workers are less likely to touch the grinding wheel and cause injury when it rotates. The bottom of the box door is located above the inner wall of the box near the ground. The push plate can push the waste from the opening of the box without opening the box door. The fixing component can prevent the box door from being easily opened relative to the box body.

[0009] Furthermore, it also includes a collection trough that can collect the waste pushed out by the pusher plate.

[0010] In the above technical solution, the collection tank can receive the waste pushed out by the pusher plate.

[0011] Furthermore, a through hole for the push plate is provided on the side wall of the housing away from its opening. The drive assembly includes a rack fixedly connected to the push plate and arranged horizontally, a push plate gear meshing with the rack, and a gear motor for driving the push plate gear to rotate.

[0012] In the above technical solution, the gear motor can drive the push plate gear to rotate, and the rotation of the push plate gear can drive the rack to move horizontally in a linear motion, thereby causing the push plate to slide horizontally. By setting through holes, when the grinding wheel is working, the waste chips that fall on the side of the push plate away from the opening of the box during the horizontal sliding process of the push plate can be pushed to the outside of the box by the push plate through the through holes.

[0013] Furthermore, a guide chute is detachably installed on the box body, which connects the through hole and the collection trough. The bottom surface of the guide chute is inclined, so that the waste leaving the through hole can enter the collection trough through the guide chute.

[0014] In the above technical solution, the waste material pushed out by the push plate through the through hole can enter the collection tank through the guide chute.

[0015] Furthermore, it also includes a cam that can contact the guide chute, the cam being driven to rotate by a cam motor, the cam being able to vibrate the guide chute.

[0016] In the above technical solution, the cam motor can drive the cam to rotate, so that the cam intermittently contacts the guide chute, so that the waste in the guide chute can enter the collection tank more fully.

[0017] Furthermore, the bottom of the collection tank is equipped with rollers.

[0018] In the above technical solution, the rollers facilitate workers in moving the collection tank.

[0019] Furthermore, the fixing component includes a magnet one embedded in the box body and a magnet two embedded in the box door, wherein the magnet one can attract the magnet two.

[0020] In the above technical solution, magnet one can attract magnet two, so that the box door is not easy to open relative to the box body.

[0021] In summary, this application has the following technical advantages: When it is necessary to clean the waste inside the chamber, the drive assembly can drive the push plate to move linearly against the inner wall of the chamber near the ground, thereby pushing the waste out of the chamber through the opening. The chamber door protects workers and the grinding wheel. With the chamber door, workers are less likely to touch the grinding wheel and be injured while it is rotating. The chamber door and the inner wall of the chamber near the ground have a vertical gap for waste to leave the chamber. The push plate can push the waste out of the chamber without opening the door, and the fixing assembly prevents the chamber door from easily opening relative to the chamber.

[0029] Please refer to the attached diagram in the instruction manual. Figure 1One embodiment of this application provides a rotor external cylindrical grinding device, including a housing 1 with an opening on one side, which is placed on a frame 16. Four mounting blocks 18 are formed on the inner wall of the housing 1. A grinding wheel 2 is rotatably mounted on every two mounting blocks 18, and a workpiece is placed on each of the two grinding wheels 2. In this embodiment, the workpiece is a rotor. A mounting frame 17 is also placed inside the housing 1, and two pressure rollers 4 are rotatably mounted on the mounting frame 17. The pressure rollers 4 are located above the grinding wheels 2, and can apply force to the grinding wheels 2 through the workpiece. The grinding wheels 2 are driven to rotate by a grinding wheel motor 3 to grind the workpiece. The mounting frame 17 is driven to slide vertically by an electric push rod 19, so that the pressure rollers 4 can be brought into contact with or moved away from the workpiece.

[0030] Please refer to the attached diagram in the instruction manual. Figure 2 The grinding wheel 2 is spaced from the inner wall of the housing 1 near the ground. A push plate 5 is located below the grinding wheel 2 and inside the housing 1. The push plate 5 is driven to slide horizontally in a straight line by a drive assembly 6. The drive assembly 6 includes a gear motor 63 detachably mounted on the outer wall of the housing 1, a push plate gear 62 coaxially and detachably mounted on the output end of the gear motor 63, and a rack 61 detachably mounted on the push plate 5. The rack 61 is embedded in the inner wall of the housing 1 and slidably connected to the housing 1. The push plate gear 62 is also embedded in the inner wall of the housing and meshes with the rack 61. During the sliding process of the push plate gear 62 driving the rack 61, the push plate 5 can slide horizontally against the inner wall of the housing 1 near the ground, thereby pushing the grinding debris from the opening of the housing 1 to the outside of the housing 1. A collection trough 9 is placed beside the frame 16. Four rollers are installed at the bottom of the collection trough 9, which can collect the debris pushed out by the push plate 5.

[0031] Please refer to the attached diagram in the instruction manual. Figure 2 and Figure 3 A door 7 is hinged to one end of the box body 1 near its opening. A handle is installed on the door 7. The projection of the door 7 on the vertical plane can cover the projection of the two grinding wheels 2 on the same vertical plane. The bottom surface of the door 7 is located above the inner wall of the box body 1 near the ground, so that when the door 7 is closed, the waste can still be pushed out of the box by the push plate. The door 7 is fixed relative to the box body 1 by a fixing component 8. The fixing component 8 includes a magnet 14 embedded in the box body 1 and a magnet 15 embedded in the door 7. The magnet 14 can attract the magnet 15 so that the door 7 will not be easily opened relative to the box body 1.

[0032] Please refer to the attached diagram in the instruction manual. Figure 4A through hole 11 is provided on the side wall of the box body 1 away from its opening for the installation of the push plate 5. A guide groove 10 is installed on the outer wall of the box body 1 away from its opening. The guide groove 10 is used to connect the through hole 11 and the collection groove 9. The bottom surface of the guide groove 10 is inclined. By setting the through hole 11 and the guide groove 10, the push plate 5 can still be used to clean the box body 1 during the workpiece grinding process. During the sliding of the push plate 5, the waste falling on the side of the push plate 5 away from the opening of the box body 1 can enter the collection groove 9 through the guide groove 10.

[0033] Please refer to the attached diagram in the instruction manual. Figure 1 and Figure 5 A cam 12 is rotatably mounted on the frame 16. The cam 12 is driven to rotate by a cam motor 13. The cam 12 can intermittently contact the bottom of the guide chute 10 so that the guide chute 10 can vibrate, so that the waste in the guide chute 10 can enter the collection tank 9 more fully.

[0034] The working principle of this embodiment is as follows: When it is necessary to clean up the waste in the box 1, the drive assembly 6 drives the push plate 5 to slide horizontally in a straight line against the inner wall of the box 1 near the ground, thereby pushing the waste into the collection trough 9. The waste that falls on the side of the push plate 5 away from the opening of the box 1 can enter the collection trough 9 through the guide chute 10.

[0035] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
