At this time, the first slide seat 35 will compress the spring 36 while moving in the slide seat 32; and at this time, the driving wheel 40 can be controlled to rotate to drive the processed gear to rotate.

[0041] Driving structure 4: When the processed gear in the bearing structure 3 is relative to the selected processing method, the third electric slide rail 42 is controlled to drive the driving wheel 40 on the frame 45 to move forward and backward for calibration; then the second electric slide rail 41 is controlled to drive the third electric slide rail 42 to move to the right, and the third electric slide rail 42 is supported on the slide plate 43 by the sliding roller 44 to move to the right, and then the driving wheel 40 on the frame 45 is brought into contact with the processed gear and pushed 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.

[0042] First gear grinding structure 5: When the processed gear is processed by the first gear grinding structure 5, the driving wheel 40 drives the processed gear to rotate and adjust the teeth in sequence according to the tooth data; and the driving wheel 40 moves the processed gear to the right, so that a single tooth is fitted with the first sandpaper 593; the second motor 52 on the base plate 51 drives the swing arm 53 to rotate in a circle, and since the swing arm 53 and the lifting arm 62 are movably connected to the swing rod 55, the swing rod 55 forms a reciprocating eccentric motion, driving the lifting arm 54 to move up and down in the lifting frame 50, that is, 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 on the first grinding frame 59 by the first clamping claw 591 fixed by the first mounting bolt 592, it can be replaced; when the corresponding teeth are processed, the second electric slide rail 41 is controlled to drive the driving wheel 40 to move left and rotate, that is, the processed gear loses power, 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.

[0043] In this embodiment, different gears have different numbers of teeth, tooth widths and tooth wall inclination angles. Therefore, the adjusting bolt 58 can be used to drive the adjusting block 57 to slide in the adjusting slot 8 of the adjusting seat 56, and the spacing between the two first grinding frames 59 and the relative inclination angle of the first grinding frame 59 on the adjusting block 57 can be adjusted to achieve matching.

[0044] The 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 rail 61 is driven to drive another group 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 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 by the pressure plate 642 fixed by the second mounting bolt 643 for easy disassembly and replacement.

[0045] 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.
