The top end of the support plate 3 is circumferentially provided with a plurality of ball bearings 8. When it is necessary to move the workpiece, the support plate 3 is lifted by the first hydraulic rod 41, thereby lifting the workpiece upward. At this time, the workpiece can be moved on the ball bearings 8 to reduce the frictional resistance and facilitate subsequent centering movement. When the workpiece is centered, the support plate 3 is lowered by the first hydraulic rod 41, and the workpiece falls on the backing plate 2.

Each lead screw 57 is threadedly arranged on the outer wall of the lifting ring 51. When it is necessary to detect and change the position of the workpiece, the bidirectional motor 58 is driven to rotate the lead screw 57, so as to lift the lifting ring 51. At the same time, the lifting ring 51 can be lowered to the lowest position, so as to facilitate the taking and placing of the workpiece and avoid affecting the subsequent machining operation.

[0029] A plurality of push arms 52 are circumferentially hingedly arranged on the inner wall of the lifting ring 51, and a gasket 53 is fixedly arranged on the free end of the push arm 52 towards one side of the rotary disc 1.

When it is detected that the workpiece is not in the middle position of the rotary disc 1, the supporting plate 3 is lifted by the first hydraulic rod 41, so that the workpiece is lifted upwards. And the second hydraulic rod 55 hinged on the fixed arm 54 is driven to work, at this time, the second hydraulic rod 55 pushes the push arm 52 to swing inward, at this time, the plurality of push arms 52 swing simultaneously, so that the workpiece is moved to the middle position of the rotary disc 1.
