When in use, the second motor 36 is controlled to start driving the corresponding driving gear 351 to drive the crown gear 35 to rotate, thereby controlling the connecting ring 34 to rotate.

[0039] Working principle: When in use, the entire automobile wheel hub processing turning device is fixed on the automobile wheel hub processing machine tool through the fixing bolts 51, and the end of the air intake elbow 433 is connected to the air outlet of the cleaning exhaust pump;

[0040] The wheel hub to be processed is placed between the multiple positioning blocks 321 in the middle of the positioning ring frame 31, and then the second motor 36 is controlled to start driving the corresponding driving gear 351 to drive the crown gear 35 to rotate, thereby controlling the connection ring 34 to rotate, thereby controlling the two driving rings 33 to rotate, and the plane thread convex is movably engaged in the corresponding plane thread groove, driving the multiple positioning frames 32 in the corresponding two groups of positioning parts to slide synchronously towards each other, thereby controlling the multiple positioning blocks 321 to slide synchronously towards each other, until the multiple positioning blocks 321 are in contact with the automobile wheel hub, and the multiple positioning blocks 321 position the automobile wheel hub;

[0041] After the automobile wheel hub is positioned, the external processing mechanism is controlled to process one side of the automobile wheel hub. When the angle of the automobile wheel hub needs to be adjusted during the processing of one side, or when the automobile wheel hub needs to be turned over after the processing of one side is completed, the first motor 6 can be controlled to drive the corresponding lifting screw 23 in the turning mechanism 2 to rotate, and the transmission of the second sprocket transmission group 233 can be coordinated to drive the corresponding lifting screw 23 in the other turning mechanism 2 to rotate, and the transmission of the first sprocket transmission group 232 can be coordinated to drive the other lifting screw 23 to rotate, thereby driving multiple lifting screws 23 in the two turning mechanisms 2. The lifting screw 23 rotates, and cooperates with the threaded installation of the inner screw tube 231 to drive the longitudinal slide frame 22 to slide upward between the two longitudinal slide frames 21, thereby driving the flip shaft rod 24 and the positioning mechanism 3 to rise, and synchronously driving the one-way bearing 26 and the transmission gear 27 to rise. At this time, the inner and outer rings of the one-way bearing 26 are self-locking, and the transmission rack 271 drives the transmission gear 27 and the driving worm 251 to rotate, thereby driving the driven worm gear 25 and the flip shaft rod 24 to rotate at different angles, and controlling the positioning mechanism 3 to rotate or flip at different angles. After the rotation or flip is completed;

[0042] The first motor 6 is controlled to start again to drive the lifting screw 23 in the corresponding flipping mechanism 2 to rotate in the opposite direction, and the transmission of the second sprocket transmission group 233 is cooperated to drive the corresponding lifting screw 23 in the other flipping mechanism 2 to rotate, and the transmission of the first sprocket transmission group 232 is cooperated to drive the other lifting screw 23 to rotate in the opposite direction, thereby driving the multiple lifting screws 23 in the two flipping mechanisms 2 to rotate in the opposite direction, and the threaded installation of the inner screw tube 231 is used to drive the longitudinal slide frame 22 to slide downward between the two longitudinal slide frames 21, thereby driving the flip shaft rod 24 and the positioning mechanism 3 to descend, and synchronously driving the one-way bearing 26 and the transmission gear 27 to descend. At this time, the inner and outer rings of the one-way bearing 26 are not self-locking, and the transmission rack 271 drives the transmission gear 27 to rotate, and the driving worm 251 cannot be driven to rotate. The driven worm wheel 25 and the flip shaft rod 24 do not rotate, so that the positioning mechanism 3 descends and maintains the adjusted angle, which is convenient for processing the automobile wheel hub at different angles and flipping processing, thereby improving the processing effect of the automobile wheel hub;

[0043] When processing the automobile wheel hub, the cleaning exhaust pump can be synchronously controlled, and the air is introduced into the two annular tubes 41 through the air intake bend 433, the third connecting pipe 431, the second connecting pipe 43, and the first connecting pipe 42. Then, the air is introduced into the corresponding air guide cylinder 45 and the exhaust cylinder 47 through multiple connecting pipes 44, and discharged through multiple exhaust grooves 473 to blow toward the automobile wheel hub, so as to synchronously clean the processed automobile wheel hub, prevent the waste chips generated during the processing of the automobile wheel hub from affecting the subsequent processing of the automobile wheel hub, thereby improving the use effect of the entire flip device.
