[0026] Working principle:

[0027] The process of fixing and grinding gear parts:

[0028] The operator places the gear workpiece between the rotating machine 11 and the fixed blocks 10. The output end of the hydraulic cylinder 9 extends, causing the fixed blocks 10 to move downwards. After the fixed blocks 10 contact the surface of the gear workpiece, they are fixed. The external power supply of the grinding mechanism 12 is connected, and the grinding gear in the grinding machine 12 is started to rotate. The external power supply of the third motor 5 is connected, and the output shaft of the third motor 5 is started to rotate, driving the threaded rod 6 to rotate. The rotation of the threaded rod 6 drives the threaded block 7 to move downwards. The threaded block 7 drives the grinding mechanism 12 to move synchronously. When the grinding mechanism 12 contacts the surface of the gear workpiece, it performs a grinding operation on the surface of the gear workpiece. When the threaded block 7 drives the grinding mechanism 12 to move to its limit position, the gear workpiece is ground. After grinding is completed, the external power supply of the rotating machine 11 is connected, and the rotating machine 11 is started to rotate, driving the gear workpiece to rotate. The above operation is reversed, causing the grinding mechanism 12 to move upwards and grind the gear workpiece again, completing the fixing and grinding process of the gear workpiece.

[0029] Auxiliary grinding process for grinding gear parts:

[0030] Since the required tooth depth varies during gear machining, the external power supply of the first motor 201 is connected, and the output shaft of the first motor 201 is started to rotate, driving the gear 203 to rotate. The rotation of the gear 203 drives the rack 204 and the push block 205 to move synchronously. The push block 205 pushes the fixed plate 207 and the gear grinding mechanism 12 to move to the right, increasing the depth of gear machining. The bolt 206 is rotated so that the end of the bolt 206 abuts against the push block 205, fixing the position of the push block 205 and completing the auxiliary gear grinding process for the gear workpiece. This process can adapt to different tooth depth requirements. When it is necessary to reduce the tooth depth, the above process can be reversed.

[0031] Auxiliary protection process for gear grinding:

[0032] Since a large amount of waste chips are generated during gear grinding, the external power supply of the second motor 301 is connected, and the output shaft of the second motor 301 is started to rotate, driving the turntable 302 and the protrusion 303 to rotate synchronously. The turntable 302 is controlled to rotate half a revolution, and under the drive of the protrusion 303, the slider 304 and the baffle 306 move upward to the limit position and then stop. The waste chips generated during processing will bounce onto the surface of the baffle 306 and will not cause injury to the operator. After the gear grinding operation is completed, the above process can be reversed to complete the auxiliary protection process for gear grinding.
