[0040] The detailed working principle and operation steps of the present invention are as follows:

[0041] S1. Replace the shaft column 38 on the first mounting tube 37 and the second mounting tube 47 according to the size of the gear shaft hole being processed and polished, and replace the corresponding drive wheel 40 at the same time. Put the drive wheel 40 on the shaft column 38 on the second mounting tube 47 and secure it with the fixing nut 39.

[0042] S2. The processed gear is mounted on the shaft column 38 on the first mounting tube 37 and is carried and driven to move by the bearing structure 3;

[0043] S3. Then, according to the processing requirements, the gear to be processed is aligned with the corresponding first gear grinding structure 5 or second gear grinding structure 6, and the driving structure 4 is controlled to drive the driving wheel 40 to be aligned with the gear to be processed and to fit the gear to be processed; the driving wheel 40 is used to push the gear to be processed to the right and move it into the first gear grinding structure 5 or the second gear grinding structure 6;

[0044] S4. The second sandpaper 644 in the first gear grinding structure 5 is raised and lowered to process a single tooth, and all teeth are processed and polished in cooperation with the driving structure 4; the upper and lower walls of the gear are polished by the second gear grinding structure 6.

[0045] The following is a detailed description of each structure:

[0046] Bearing structure 3: When the gear to be processed is mounted on the shaft column 38 in the bearing structure 3, the first electric slide 31 supported by the support 30 can be driven, and the slide 32 is driven by the first electric slide 31 to move back and forth to adjust the gear to be processed relative to the corresponding first grinding structure 5 or the second grinding structure 6; when the driving wheel 40 in the driving structure 4 moves to the right and engages with the gear to be processed, the slide rod 33 installed by the first nut 34 is driven to move to the right to limit the processing, and the gear to be processed is driven into the first grinding structure 5 or the second grinding structure 6. At this time, the first slide 35 compresses the spring 36 while moving in the slide 32; and at this time, the driving wheel 40 is controlled to rotate to drive the gear to be processed to rotate.

[0047] Driving structure 4: When the processing mode is selected relative to the processed gear in the supporting structure 3, the third electric slide 42 is controlled to drive the driving wheel 40 on the frame 45 to move back and forth for calibration; then the second electric slide 41 is controlled to drive the third electric slide 42 to move to the right, and the third electric slide 42 is supported on the slide plate 43 by the sliding roller 44 to move to the right, thereby causing the driving wheel 40 on the frame 45 to contact and engage with the processed gear and push it to the right; when the processed gear enters the first grinding structure 5 or the second grinding structure 6, the first motor 46 can be driven, and the driving wheel 40 is driven to rotate with the help of the second bearing 72 through the transmission of the pulley 48 and the belt 49, thereby driving the processed gear to rotate.

[0048] First gear grinding structure 5: When the gear being processed passes through the first gear grinding structure 5, the drive wheel 40 drives the gear being processed to rotate and adjust its teeth in sequence according to the tooth data. The drive wheel 40 also moves the gear being processed to the right, so that a single tooth is aligned with the first sandpaper 593. The second motor 52 on the base plate 51 drives the swing arm 53 to rotate in a circular motion. Since the swing arm 53 is movably connected to the lifting arm 62, the swing arm 55 generates a reciprocating eccentric motion, driving the lifting arm 54 to move up and down within the lifting frame 50, thereby driving the first sandpaper 593 on the first grinding frame 59 to move up and down for grinding. Since the first sandpaper 593 is clamped to the first grinding frame 59 by the first clamping jaw 591 fixed by the first mounting bolt 592, it can be replaced. When the corresponding tooth is processed, the second electric slide 41 is controlled to drive the drive wheel 40 to move and rotate to the left, so that the gear being processed loses its force and is separated from the first grinding frame 59 by the reverse force of the spring 36, and then rotates to adjust the next tooth.

[0049] In this embodiment, since different gears have different numbers of teeth, tooth widths, and tooth wall inclination angles, the adjustment block 57 can be driven to slide in the adjustment slot 8 of the adjustment seat 56 by adjusting the adjustment bolt 58, and the spacing between the two first grinding frames 59 and the relative inclination angle of the first grinding frame 59 on the adjustment block 57 can be adjusted to achieve matching.

[0050] Second gear grinding structure 6: When the upper and lower walls of the processed gear need to be ground, the processed gear is pushed to the right by the driving wheel 40 and enters the grinding assembly 64 supported by the support leg 63. At this time, the lower wall of the processed gear contacts the second sandpaper 644 on the grinding frame. Different gears have different thicknesses, so the fourth electric slide 61 is driven to drive another set of grinding assemblies 64 to descend through the support arm 62, and the second sandpaper 644 in the other grinding assembly 64 is attached to the upper wall of the gear. The processed gear can then be driven to rotate by the driving wheel 40 to grind the upper and lower walls; at the same time, the second sandpaper 644 is clamped on the second grinding frame 641 with the help of the pressure plate 642 fixed by the second mounting bolt 643 for easy disassembly and replacement.

[0051] In this embodiment, the second gear grinding structure 6 grinds the upper and lower walls of gears of different thicknesses. Since the shaft column 38 is replaceable, if the length of the shaft column 38 is the same as the thickness of the gear being processed, the upper wall of the gear being processed is not blocked. If the length of the shaft column 38 is greater than the thickness of the gear being processed, part of the shaft column 38 will be in the middle of the upper wall of the gear being processed; therefore, when the gear enters the second gear grinding structure 6, the shaft column 38 is located on the left side of the second grinding frame 641, and only the teeth and part of the gear body of the gear being processed enter.

[0052] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
