Technical Field

[0001] This utility model relates to the field of motor stator core processing technology, and in particular to a motor stator core surface grinding device. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. Its main function is to generate driving torque and serve as a power source for electrical appliances or various machines. The stator is the stationary part of the motor, and its main function is to generate a rotating magnetic field. The rotor's main function is to be cut by magnetic lines of force in the rotating magnetic field, thereby generating (outputting) current. During the production process of the stator core, it is necessary to grind the stator core to make its surface smooth, reduce friction, and make it more conducive to subsequent production and use, thereby improving the performance of the motor.

[0003] During the grinding process of motor stator core, a lot of dust and debris are generated. The dust and debris generated during grinding will pollute the production space and also harm the health of workers, which is not conducive to the processing operation. Utility Model Content

[0005] A grinding device for the surface of a motor stator core includes a processing table and a grinding mechanism and a dust prevention mechanism mounted on the processing table. The grinding mechanism includes a drive assembly and a grinding assembly. The drive assembly includes an electric cylinder, a pressure application part, a motor, a chain, and drive rollers. The electric cylinder is mounted on the processing table via a bracket. The pressure application part is fixedly mounted at the output end of the electric cylinder. Two drive rollers are rotatably mounted on the processing table via bearing seats. The output end of the motor is connected to one of the drive rollers via the chain.

[0006] The grinding assembly includes a second motor, a lead screw, a guide rail, a slide block, a screw rod, a support plate, and a grinding machine. The lead screw is fixedly connected to the output end of the second motor. The slide block is drivenly connected to the lead screw and slides along the guide rail. The screw rod is fixedly installed on the slide block. The support plate is sleeved on the screw rod and its height can be limited by the nut on the screw rod. The grinding machine is fixedly installed on the support plate.

[0007] The dustproof mechanism includes a protective plate, an air extraction port, and a baffle.

[0018] Move the grinder upwards so that the grinding wheel at the output end of the grinder can contact the surface of the motor stator core. Turn the nut on the screw to fix the height of the support plate on the screw. This height can be adjusted according to the diameter of the motor stator core. Grind the motor stator core. The shield can cover the port of the protective plate to reduce the dust and debris from spreading.

[0023] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0024] Reference Figure 1-3 A grinding device for the surface of a motor stator core includes a processing table 1 and a grinding mechanism and a dustproof mechanism mounted on the processing table 1. The grinding mechanism includes a drive assembly and a grinding assembly. The drive assembly includes an electric cylinder 3, a pressure applying part 4, a motor 5, a chain 6, and a drive roller 7. The electric cylinder 3 is mounted on the processing table 1 via a bracket 2. The pressure applying part 4 is fixedly mounted at the output end of the electric cylinder 3. Two drive rollers 7 are rotatably mounted on the processing table 1 via bearing seats. The output end of the motor 5 is connected to one of the drive rollers 7 via the chain 6.

[0025] The grinding assembly includes a second motor 10, a lead screw 11, a guide rail 12, a slide 14, a screw 15, a support plate 16, and a grinding machine 17. The lead screw 11 is fixedly connected to the output end of the second motor 10. The slide 14 is drivenly connected to the lead screw 11 and slides along the guide rail 12. The screw 15 is fixedly installed on the slide 14. The support plate 16 is sleeved on the screw 15 and its height can be limited by the nut on the screw 15. The grinding machine 17 is fixedly installed on the support plate 16.

[0026] The dustproof mechanism includes a protective plate 8, an air extraction port 9, and a baffle 18. The protective plate 8 is installed at the rectangular opening in the middle of the processing table 1, and its upper two sides are respectively attached to one side of the lower end of the two drive rollers 7. The air extraction port 9 is opened at the bottom of the protective plate 8 for connecting to the external vacuum cleaner pipe. The baffle 18 consists of two sliding inserts on the other two sides of the upper end of the protective plate 8.

[0027] The motor stator core can be placed in the middle between the two drive rollers 7, and then the electric cylinder 3 is driven to push the pressure part 4 downward to apply pressure to the motor stator core, and push the cover plate 18 closer to the end of the motor stator core, but without contacting the end of the motor stator core.

[0028] Move the grinder 17 upward so that the grinding wheel at the output end of the grinder 17 can contact the surface of the motor stator core. Then rotate the nut on the screw 15 to fix the height of the support plate 16 on the screw 15.

[0029] At this time, the drive motor 5 can drive one of the drive rollers 7 to rotate through the chain 6. The drive roller 7 can drive the motor stator core to rotate, while the other drive roller 7 provides auxiliary support for the rotation.

[0030] The drive motor 10 drives the slide 14 to move along the screw 15 via the lead screw 11. The slide 14 can drive the grinder 17 on the support plate 16 to move via the screw 15, thereby reciprocating grinding of the surface of the motor stator core by the grinder 17.

[0031] An external vacuum cleaner can be activated to remove dust generated during the polishing process through the air intake 9, preventing the dust from affecting the workspace.

[0032] Above the lead screw 11 and between the support plate 16 and the slide block 14, there is a shielding part 13 with both ends fixed on the processing table 1. The shielding part 13 is arranged in an arc shape. The shielding part 13 can effectively prevent dust and debris from accumulating on the lead screw 11 and affecting the normal use of the lead screw 11.

[0033] The pressure application part 4 includes an arc-shaped plate and rollers. The rollers are two opposing rollers that are rotatably mounted on the arc-shaped plate. When the pressure application part 4 moves downward, the rollers contact the surface of the motor stator core, which restricts the motor stator core without affecting its normal rotation.

[0034] There are four screws 15, which are located near the four corners of the slide block 14. Since the diameter of the motor stator core produced may vary, after the motor stator core is placed on the drive roller 7, the height of the grinder 17 can be adjusted. The nut on the screw 15 is rotated to fix the support plate 16 on the screw 15, thereby positioning the height of the grinder 17.

[0035] The center point of the protective plate 8 is set on the same vertical section as the rectangular opening in the middle of the processing table 1 and the symmetrical line of the two drive rollers 7; to ensure that the grinding wheel of the grinding machine 17 is directly below the stator core of the motor for grinding.

[0036] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
