Installation card slot 511 has all been seted up to the inside left and right sides of two sets of rotor plates 118, adopt this kind of design to be convenient for make can be at rotor plate 118 internally mounted balancing weight, centrifugal force is bigger when making rotor plate 118 rotate, it is better to make the effect of polishing, and support base 111 left end medial side fixedly connected with guide board 512, fixedly connected with baffle 513 is gone up at both ends around guide board 512, adopt this kind of design to be convenient for make the device can guide the work piece of releasing, do benefit to subsequent accomodating.

The working principle is as follows: when the device is used, firstly, the workpiece is placed inside the storage tank 113 in parallel with the support base 111, the workpiece inside the storage tank 113 is guided by the discharging tank 114 and drops to the position above the support rod 226, when the workpiece drops to the position above the support rod 226, the workpiece above the support rod 226 abuts against the workpiece inside the discharging tank 114, so that the workpiece inside the discharging tank 114 cannot drop, then the control switch 115 is pressed to control the electric push rod 116 to work, when the electric push rod 116 works, the rotating block 223 is driven to move leftwards, when the rotating block 223 moves leftwards, the fixed sleeve block 222 is driven to move leftwards, so that the spline shaft 117 moves leftwards, and when the spline shaft 117 moves leftwards, the rotating plates 118 on two sides can enter the workpiece.

When the top end of the electric push rod 116 moves leftwards, the first connecting rod 311 is also driven to move leftwards, when the first connecting rod 311 moves leftwards, the first abutting blocks 312 on the two sides are driven to move leftwards and abut against the second abutting blocks 318 on the two sides, so that the two groups of second abutting blocks 318 are close to each other, the two groups of clamping plates 316 are driven to be close to each other, the workpiece is clamped, and when the two groups of clamping plates 316 are close to each other, the two groups of second springs 317 are also deformed.

When the ejecting end of the electric push rod 116 moves leftwards, the approach switch 224 is close to the fixed sleeve 222, so as to control the motor 215 to drive the first belt pulley 216 to rotate, the first belt pulley 216 rotates to drive the transmission belt 218 to rotate, the second belt pulley 217 rotates to drive the movable sleeve 213 to rotate, the movable sleeve 213 rotates to drive the spline shaft 117 to rotate, the spline shaft 117 rotates to drive the two sets of rotating plates 118 at the two sides to rotate, centrifugal force is generated during rotation, so that the two sets of abrasive paper 119 at the two sides are tightly abutted against and rotate with the inner wall of the workpiece, thereby polishing the inner wall of the workpiece, simultaneously, the two sets of first springs 221 at the two sides are deformed, after the workpiece is polished, the electric push rod 116 works again, so that the ejecting end of the electric push rod 116 moves rightwards, and the approach switch 224 is far away from the fixed sleeve 222, thereby controlling the motor 215 to stop rotating, so that the two sets of first springs 221 at the two sides are deformed again, stopping polishing the workpiece, and when the electric push rod 116 moves rightward, the two sets of first abutting blocks 312 are also enabled to release the abutting against the two sets of second abutting blocks 318, and at this moment, the two sets of second springs 317 are deformed again, so as to drive the two sets of clamping plates 316 to be away from each other, thereby releasing the clamping of the workpiece.

When the ejecting end of the electric push rod 116 moves rightwards, the electric push rod can drive the ejecting plate 417 to move rightwards, when the ejecting plate 417 moves rightwards, the second rack plate 419 can be driven to move rightwards, so that the transmission gear 416 rotates anticlockwise, when the transmission gear 416 rotates anticlockwise, the first rack plate 414 can be driven to move leftwards, when the first rack plate 414 moves leftwards, the movable plate 412 can be driven to move leftwards, so that the workpiece above the supporting rod 226 is moved out, at the moment, the workpiece in the blanking groove 114 can move downwards and fall above the supporting rod 226, workpiece loading is completed, the electric push rod 116 is continuously controlled to work through the control switch 115, so that the ejecting end of the electric push rod 116 moves leftwards, the second rack plate 419 moves leftwards, so that the movable plate 412 is driven to move rightwards to restore the initial position, and the next workpiece is pushed out continuously.
