Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0026] Referring to Figures 1 - 6 , a stator deburring device includes a base 1. A lifting cylinder 2 is fixedly installed on the base 1 through a support arm. The output end of the lifting cylinder 2 is fixedly installed with a rotary motor 3 through a mounting plate. The output shaft of the rotary motor 3 is installed with a rotating rod 4 through a connecting component. A cylindrical groove is opened at the lower end of the rotating rod 4. A push rod 6 is vertically slidably installed in the cylindrical groove through a telescopic spring 5.

[0027] The lifting cylinder 2 can drive the rotary motor 3 to move vertically downward through the mounting plate. The push rod 6 can only move vertically up and down in the cylindrical groove, and there is no relative rotation between the push rod 6 and the rotating rod 4. When the rotary motor 3 is started, the rotating rod 4 and the push rod 6 can be driven to rotate by the output shaft of the rotary motor 3.

[0028] A placing disk 7 is fixedly installed on the base 1. A clamping component for clamping the stator is provided on the placing disk 7. The clamping component includes a plurality of telescopic cylinders 11 fixedly installed on the base 1 and a plurality of positioning blocks 12. The plurality of positioning blocks 12 are respectively fixedly connected to the output ends of the plurality of telescopic cylinders 11. The plurality of telescopic cylinders 11 are arranged in a circumferential manner centered on the placing disk 7.

[0029] When deburring the stator, first place the stator on the placement plate 7, and then simultaneously start multiple telescopic cylinders 11 to drive multiple positioning blocks 12 to approach each other and move towards the stator until the positioning blocks 12 contact the stator, thereby clamping and fixing the stator on the placement plate 7 to prevent the stator from shifting during deburring.

[0030] Multiple telescopic rods 8 are horizontally and fixedly installed on the ejector rod 6. The ends of the multiple telescopic rods 8 away from the ejector rod 6 are all fixedly installed with abrasive blocks 9. Support rods 10 are rotatably installed on the multiple abrasive blocks 9. The ends of the support rods 10 away from the abrasive blocks 9 are rotatably connected to the rotating rod 4.

[0031] Drive the rotary motor 3 to move vertically downward through the lifting cylinder 2, and drive the rotating rod 4, the ejector rod 6, and multiple abrasive blocks 9 to insert into the inner ring of the stator until the lower end of the ejector rod 6 contacts the base 1, restricting the continued movement of the ejector rod 6. At this time, the ejector rod 6 moves in the cylindrical groove opened in the rotating rod 4, the telescopic spring 5 is compressed, and the ejector rod 6 and the rotating rod 4 move relative to each other. At this time, the abrasive block 9 will be driven by the support rod 10 to move away from the ejector rod 6, and the telescopic rod 8 extends until multiple abrasive blocks 9 all contact the inner ring of the stator. Then drive the rotary motor 3, and drive the abrasive blocks 9 to rotate in the inner ring of the stator through the rotating rod 4 and the support rod 10. During the rotation process, the deburring of the inner ring of the stator is realized. The mutual movement of the multiple abrasive blocks 9 enables the cleaning of stators with different inner diameter sizes without replacing cutting tools with different radii, which is convenient to operate and effectively improves the practicability of the device.

[0032] The connection assembly includes multiple connection blocks 13 fixedly welded on the output shaft of the rotary motor 3 and a threaded sleeve 14 sleeved on the output shaft of the rotary motor 3. A connection groove 15 is opened at the upper end of the rotating rod 4, and multiple card slots 16 communicated with the connection groove 15 are opened at the upper end of the rotating rod 4. One end of the output shaft of the rotary motor 3 is inserted into the connection groove 15, and the multiple connection blocks 13 are respectively inserted into the multiple card slots 16. Threads are opened at the upper end of the rotating rod 4, and the threaded sleeve 14 is threadedly connected to the rotating rod 4. The threaded sleeve 14 is sleeved on the output shaft of the rotary motor 3, and the threaded sleeve 14 is located above the multiple connection blocks 13.

[0033] When the threaded sleeve 14 is threadedly connected to one end of the rotating rod 4, it can restrict the multiple connection blocks 13 from moving out of the card slots 16, so that the rotating rod 4 is connected to the output shaft of the rotary motor 3. When the rotating rod 4 needs to be disassembled, the threaded sleeve 14 can be rotated to separate the threaded sleeve 14 from the threads opened at one end of the rotating rod 4. Then the multiple connection blocks 13 can be removed from the card slots 16, and one end of the output shaft of the rotary motor 3 can be removed from the connection groove 15 to complete the disassembly of the output shaft of the rotary motor 3 and the rotating rod 4, realizing the quick installation of the rotating rod 4 and the output shaft of the rotary motor 3, thus facilitating the replacement of the abrasive block 9.

[0034] A rotating disk 17 is rotatably connected to the center of the placing disk 7. The lower end of the ejector rod 6 contacts the rotating disk 17, and one end of the ejector rod 6 contacts the rotating disk 17. When the rotating motor 3 drives the ejector rod 6 to rotate, the rotating disk 17 can be driven to rotate on the placing disk 7, thereby reducing the friction between the ejector rod 6 and the placing disk 7.

[0035] Spherical grooves are formed at the lower ends of a plurality of abrasive blocks 9, and balls 18 are rotatably engaged in the plurality of spherical grooves. When the abrasive blocks 9 rotate within the inner ring of the stator, the lower ends of the abrasive blocks 9 are in rolling contact with the surface of the placing disk 7 through the balls 18, thereby preventing friction between the abrasive blocks 9 and the placing disk 7.

[0036] In the present utility model, the lifting cylinder 2 drives the rotating motor 3 to move vertically downward, and drives the rotating rod 4, the ejector rod 6 and a plurality of abrasive blocks 9 to insert into the inner ring of the stator until the lower end of the ejector rod 6 contacts the base 1. At this time, the ejector rod 6 moves within the cylindrical groove formed in the rotating rod 4, and the telescopic spring 5 is compressed. At the same time, the support rod 10 drives the abrasive blocks 9 to move away from the ejector rod 6 until a plurality of abrasive blocks 9 all contact the inner ring of the stator. The rotating motor 3 is driven to drive the abrasive blocks 9 to rotate within the inner ring of the stator to clean the burrs on the inner ring of the stator. The mutual movement of the plurality of abrasive blocks 9 enables the cleaning of stators with different inner diameter sizes without the need to replace cutting tools with different radii, which is convenient to operate and effectively improves the practicability of the device.

[0037] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
