Detailed Implementation

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figs. 1-3 As shown in the figure, this utility model embodiment proposes a gear grinding device, comprising:

[0022] C-type bracket 1;

[0023] Grinding structure; The grinding structure includes an electric push rod 3 mounted on a C-shaped bracket 1, and a grinding block 9 is installed at the output end of the electric push rod 3;

[0024] Gear positioning structure; The gear positioning structure includes a drive shaft 5 that is rotatably connected to a C-shaped bracket 1. A motor frame 4 is fixedly connected to the C-shaped bracket 1. A stepper motor 2 is mounted on the motor frame 4. Bevel gears 6 are mounted on the output end of the stepper motor 2 and on the drive shaft 5. The two bevel gears 6 mesh with each other. When the stepper motor 2 works, it drives the bevel gears 6 and the drive shaft 5 to rotate, thereby enabling the circular plate 7 to rotate.

[0025] A circular plate 7 is fixedly connected to the upper end of the drive shaft 5. A rectangular groove 8 is provided at the upper end of the circular plate 7. An electromagnet 17 is fixed in the rectangular groove 8. A permanent magnet 10 slides in the rectangular groove 8 and abuts against the electromagnet 17. The magnetic poles of the electromagnet 17 and the permanent magnet 10 are opposite. The permanent magnet 10 can also be replaced with a magnetic material that attracts the electromagnet 17. A fixed shaft 11 is fixedly connected to the upper end of the permanent magnet 10. A protrusion 12 is fixed on the outer wall of the fixed shaft 11 and is arranged along the axial direction. The fixed shaft 11 is opposite to the hole on the gear, and the protrusion 12 is opposite to the keyway, so as to position the gear.

[0026] It also includes a dust removal mechanism; the dust removal mechanism includes a dust collection box 13 installed on the outside of the C-shaped bracket 1, a fan 14 installed on the dust collection box 13, an annular plate 16 coaxially rotatably connected to the upper end of the circular plate 7, a conveying pipe 15 installed at the upper end of the dust collection box 13, the conveying pipe 15 passing through the annular plate 16 and fixedly connected, a dust filter 18 installed inside the dust collection box 13, the air inlet end of the fan 14 and the conveying pipe 15 are located on the upper and lower sides of the dust filter 18, and the conveying pipe 15 is set close to the upper end of the circular plate 7.

[0027] The detailed working process of this utility model is as follows:

[0028] 1. When grinding the gear, the worker places the gear on the circular plate 7. The mounting holes and keyways on the gear fit onto the fixed shaft 11 and the protrusion 12. Due to the rectangular groove 8 and the cooperating permanent magnet 10, the fixed shaft 11 and the protrusion 12 can be positioned so that they will not rotate. Therefore, the gear can be positioned so that it is not easy to rotate. Then, the electric push rod 3 is started to drive the grinding block 9 to move down and abut against the upper end of the gear, which also has the effect of limiting the gear.

[0029] 2. Start the stepper motor 2. The stepper motor 2 drives the bevel gear 6, drive shaft 5, circular plate 7 and gear to rotate. The rotating gear can be polished by the stationary grinding block 9. Due to the centrifugal force of the gear rotation, some debris flies out. Under the limit of the annular plate 16, the debris falls between the circular plate 7 and the annular plate 16.

[0030] 3. Start the fan 14. The fan 14 will discharge the air in the dust filter box 13, thereby creating a negative pressure at the end of the conveying pipe 15. This will draw the debris and dust generated during grinding into the dust filter box 13, thus achieving the treatment and collection of debris and dust.

[0031] 4. Since the gears are different, their mounting holes and keyways are different. Turn off the power to the electromagnet 17, then move the fixed shaft 11 up to remove it, and then install the matching fixed shaft 11. The disassembly and assembly are convenient and simple.

[0032] Finally, it is explained that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the purpose and scope of the present application. The technical solutions of the present application should be covered in the scope of the claims of the present application.
