[0059] During specific use, technicians in this field place the parts that need to be ground between the two groups of pressing plates 324, start the cylinder 323, so that the cylinder 323 drives the two groups of pressing plates 324 to clamp and fix the parts to be ground, and then start the clamping cylinder 224 to clamp and position the front and rear ends of the clamping block 313 to prevent the turnover mechanism 3 from moving, and grind the parts to be ground by the gear grinding machine. When the grinding is completed, start the drive motor 122 to drive the drive motor 122 to drive the rotating rod 123 and the sliding plate 124 to move the gear grinding machine. The block 124 rotates, thereby driving the gear rod 141 and the annular slide rail 143 to move toward the right end first, thereby driving the rotating gear 212 and the first swing arm 221 to swing the arm, so that the first swing arm 221 contacts the right end of the limit plate 421 and is blocked and positioned by the right end of the limit plate 421, and the left end of the revolving mechanism 3 is inserted into the interior of the limit groove 422, so that the docking tooth 312 is meshed and connected with the groove of the steel belt 437, and at the same time, the clamping cylinder 224 is started again to release the clamping of the revolving mechanism 3, and the sliding block 124 is driven continuously by the driving motor 122 to make the sliding block 124 move to the right end of the revolving mechanism 3. The block 124 drives the slide rail 132 to move in the opposite direction, thereby driving the second swing arm 231 to swing. Since the right end of the gear rod 141 and the slide rod 142 is longer than the left end, the swing arm arc of the second swing arm 231 is longer than the first swing arm 221. Therefore, after the arc gear rod 237 rotates to the right, it first drives the first gear 431 to drive and swings through the meshing area of ​​the first gear 431, so that the first gear 431 drives the second gear 432, the third gear 433 and the fourth gear 435 to rotate. The diameters of the third gear 433 and the fourth gear 435 are not equal, so the first gear 431 can accelerate the rotation of the fourth gear 435, so that the steel belt 437 drives the revolving mechanism 3 to rise, and the revolving mechanism 3 drives the grinding component to move upward and be taken away by the clamping mechanism. When the second swing arm 231 swings back, the arc-shaped gear rod 237 contacts the first gear 431 again to drive the revolving mechanism 3 back to the bottom, and through the reciprocating swing of the first swing arm 221, the revolving mechanism 3 is transported to the initial position again, so as to facilitate the next gear grinding operation.
