Preferably, the inner surface of the rotating ring 56 is uniformly provided with balls 561; the balls 561 are free to rotate; the balls 561 are in contact with the inner side wall of the annular groove on the base 54; when the rotary ring 56 rotates, and the gap between the rotary ring 56 and the base 54 is small, so that the rotary ring 56 and the base 54 generate large friction in the working process, the rotary ring 56 is abraded and generates heat, and the balls 561 uniformly arranged on the inner surface of the rotary ring 56 can rotate freely, so that the friction force between the rotary ring 56 and the inner side wall of the annular groove on the base 54 can be effectively reduced, the abrasion degree of the rotary ring 56 is reduced, and the heat generation is reduced when the rotary ring 56 rotates.

The specific working process is as follows:

when the automatic feeding device works, a workpiece to be machined is conveyed to the upper feeding device 35 through the conveying belt, the workpiece is clamped and placed on the clamp 34 through the feeding and discharging device 35, then the first motor 23 is started, when the first motor 23 runs, the transmission belt 42 is driven to move through the meshing between the gear on the shaft of the first motor 23 and the transmission belt 42, the transmission belt 42 is fixedly installed on the clamp 34, and meanwhile, the clamp 34 can slide along the sliding rail 43 in the sliding rail 43, so that the workpiece is driven to move; meanwhile, a plurality of electromagnets 4 installed on the side walls of the shot blasting box 3 are started to generate electromagnetic force, so that the toothed ring 41 opposite to the electromagnets 4 is attracted, and the toothed ring 41 can keep a relatively static state and does not move along with the clamp 34; because the two ends of the slide rail 43 are positioned in the shot blasting box 3, the clamp 34 is driven by the first motor 23 to move along the slide rail 43, so that the workpieces fixed on the clamp 34 are driven to enter the shot blasting box 3 together, and after the machining in the shot blasting box 3 is finished, the workpieces come out from the other side of the shot blasting box 3 along with the clamp 34 and are taken down by the waiting loading and unloading device 35; after the workpiece is taken down, another loading and unloading device 35 puts the unprocessed workpiece on the clamp 34 again, so that the workpiece enters another shot blasting box 3 along with the operation of the clamp 34 for processing; the blower 21 mounted on the grid plate 11 is started to generate high-pressure air which enters the mixer 22 through a pipeline, meanwhile, the pills in the sand box 2 enter the mixer 22 through a pipeline, the pills in the mixer 22 from the sand box 2 are stirred by the high-pressure air, the high-pressure air carrying the pills is carried into the pipeline from the outlet, the high-pressure air carrying the pills enters the fixing plate 31 in the shot blasting box 3 through a pipeline and is uniformly sprayed out through the shot blasting heads 32 on the fixing plate 31, thereby completing the shot blasting work on the workpiece, meanwhile, the shot blasting heads 32 on the two ends of the fixing plate 31 are obliquely mounted, and the shot blasting heads 32 in the middle part of the fixing plate 31 are vertically mounted to ensure that the pills sprayed out by the shot blasting heads 32 are right hit on the workpiece to the; the suction pump 24 mounted on a first plate 12 is started and provides negative pressure, the negative pressure generated by the suction pump 24 is conducted to the collecting port 33 in the shot box 3 through a pipeline, the shot which completes the work falls into the shot box 3, the negative pressure exists in the collecting port 33 arranged at the bottom of the shot box 3, and therefore the falling shot sucks the collecting port 33 to be collected, and meanwhile, the shot is prevented from being accumulated in the shot box 3 and preventing the slide rail 43 from running; when the conveying belt conveys the workpiece to the loading and unloading device 35, the second motor 6 operates to drive the screw 61 arranged on the driving shaft of the second motor 6 to operate, so as to drive the sliding table 62 through which the screw 61 passes to move, after the sliding table 62 reaches a designated position, the third motor 64 arranged on the sliding table 62 through the bracket 63 operates, and further drives the second cylinder 65 arranged on the shaft of the third motor 64 to rotate, after the second cylinder 65 rotates to the designated position, the second cylinder 65 is started, the clamping jaw 66 is driven to rotate by the extension of the piston of the second cylinder 65, the workpiece is clamped, after the workpiece is clamped, the third motor 64 reversely operates, after the second cylinder 65 rotates to the initial position parallel to the screw 61, the second motor 6 operates, the sliding table 62 is driven to the designated position through the operation of the screw 61, so that the workpiece clamped on the clamping jaw 66 is just positioned on the clamp 34, after the clamp 34 clamps the workpiece, the second cylinder 65, loosening the clamping jaw 66, starting the second motor 6, retreating the sliding table 62, driving the clamping jaw 66 to be far away from the clamp 34, completing the feeding work, and performing opposite actions during the blanking; after the loading and unloading device 35 places the workpiece on the clamp 34, the first air cylinder 55 is started, so that the bearing plates 59 arranged at the tail ends of the extending ends of the first air cylinder 55 are lifted, and the workpiece is fixed on the clamp 34 through the movement of the bearing plates 59 at the two ends of the clamp 34; because the toothed ring 41 is fixed by the electromagnet 4, the clamp 34 passes through the toothed ring 41 and moves along the toothed ring 41, the toothed ring 41 is meshed with the rotating ring 56 in the hole of the toothed ring 41, when the clamp 34 moves, the rotating ring 56 is driven to rotate by the teeth meshed with the toothed ring 41, and because the center position of the transmission film 58 is positioned on the bearing plate 59, the edge of the transmission film is fixedly connected to the rotating ring 56, and the bearing plate 59 is rotatably arranged on the extending end of the cylinder I55, the transmission film 58 drives the bearing plate 59 to rotate together when the rotating ring 56 rotates, and then the workpiece fixed by the bearing plate 59 rotates when the clamp 34 moves; because the bearing plate 59 rotates, the fan blades 57 arranged on the bearing plate 59 rotate along with the bearing plate, the heat generated by the operation of the parts such as the air cylinder, the rotating ring 56 and the like in the transmission membrane 58 is discharged through the reserved holes by the airflow generated after the fan blades 57 rotate, and when the air in the transmission membrane is discharged by the fan blades 57, the external cold air enters the inner side of the transmission membrane through the micropores in the transmission membrane; meanwhile, the cooling air nozzle 51 on the clamp 34 is connected with an external air source through a first air passage to blow the transmission film 58, so that the temperature of the transmission film 58 is reduced, the service life of the transmission film 58 is prolonged, the cost is reduced, and in addition, heat exhausted by the fan blades 57 is ejected from the preheating air nozzle 52 through a second air passage 53; the transmission film 58 is arranged between the rest rotating rings 56 of the bearing plate 59, and the transmission film has tension due to the material of the transmission film, so that the bearing plate 59 has a tendency of moving towards the first air cylinder 55 under the action of the tension, and the bearing plate 59 has initial tension towards the first air cylinder 55, thereby avoiding the insufficient pressure of the bearing plate 59 on a workpiece when the air source pressure is insufficient; because the swivel 56 rotates and the gap between the swivel 56 and the base 54 is small, during the operation, the swivel 56 and the base 54 generate large friction, which causes the swivel 56 to wear and generate heat, and the balls 561 uniformly installed on the inner surface of the swivel 56 can rotate freely, so that when the swivel 56 rotates, the friction between the swivel 56 and the base 54 can be effectively reduced, the wear degree of the swivel 56 can be reduced, and the heat generation can be reduced.
