The end part of the output shaft of the driving air cylinder 5 is provided with a claw 10, and the driving air cylinder 5 moves downwards to enable the claw 10 to clamp the shaft parts. The sliding frame 4 slides to enable the shaft part to be separated from the three-jaw chuck 2, and the driving air cylinder 5 is connected to the sliding frame 4 in a rotating mode, so that the driving air cylinder 5 rotates to drive the shaft part to turn. After the shaft parts are turned, the sliding frame 4 drives the driving cylinder 5 to move along the extending direction of the axial guide rail 3, so that the end parts of the shaft parts enter the three-jaw chuck 2 again. Thereby can carry out the centre gripping and turn to axle class when processing axle type part, reduce the phenomenon that axle type part burns staff, the effectual manpower of having saved has promoted the security of production.

For facilitating the clamping of the shaft parts by the clamping jaws 10, the clamping jaws 10 comprise mounting blocks 101 fixed on the output shaft of the driving cylinder 5, and the mounting blocks 101 are in a square shape and are horizontally arranged. A pair of oppositely arranged curved clamping strips 102 are hinged on the mounting block 101, and the hinge axes between each curved clamping strip 102 and the mounting block 101 are respectively parallel to the rotation axis of the three-jaw chuck 2.

The positional relationship between the axis of articulation between the curved clamping bar 102 and the mounting seat and the axis of rotation of the three-jaw chuck 2 is defined to facilitate the clamping of shaft-like parts by the entire jaws 10. When the two curved clamping strips 102 are turned towards the direction away from each other, the distance between the two curved clamping strips 102 and the end part of the shaft part is pulled away, so that the two curved clamping strips 102 can conveniently clamp the shaft part. Extension strips 104 are arranged at the ends of the curved clamping strip 102, and the extension directions of the two extension strips 104 are defined, so that the ends of the two extension strips 104 far away from the curved clamping strip 102 are in an open shape as a whole. The extension strips 104 and the corresponding curved clamping strips 102 are in transition through a curved surface, so that the shaft parts can conveniently slide between the two curved clamping strips 102. Springs 105 are disposed on both the two curved holding bars 102, respectively, and the springs 105 are connected to the mounting block 101, so that the opening and closing of the two curved holding bars 102 are realized by the elastic force of the springs 105.

A second cylinder 12 is arranged on the axial guide 3 to power the sliding carriage 4.

In summary, when the shaft-like part is machined, one end of the shaft-like part is clamped on the three-jaw chuck 2, and then the shaft-like part is turned. After the turning is finished, the driving cylinder 5 is opened, and an output shaft of the driving cylinder 5 drives the whole clamping jaw 10 to move towards the direction close to the shaft parts. When the jaws 10 contact the shaft-like part, the shaft-like part is clamped between the two extending strips 104, slides along the inclined plane between the extending strips 104 and the curved holding strips 102, and slides into the space between the two curved holding strips 102. The shaft part applies pressure to the two curved clamping strips 102 in the process of being clamped between the two curved clamping strips 102, so that the spring 105 is in a compressed state. When the shaft part enters the clamping cavity 103 formed between the two curved clamping bars 102, the pressure applied to the spring 105 is reduced and the spring begins to reset, so that the two curved clamping bars 102 begin to close under the action of the spring 105, and the shaft part is clamped between the two curved clamping bars 102. The three-jaw chuck 2 is then opened and the carriage 4 is pushed in translation by the action of the second cylinder 12, so that the shaft-like part is released from the three-jaw chuck 2. Then, the driving cylinder 5 is rotated, so that the driving cylinder 5 drives the shaft part to turn, and the end of the shaft part which is not turned faces the turning tool. The second cylinder 12 is driven again to move the carriage 4 along the axial guide 3 and drive the shaft part to be clamped into the three-jaw chuck 2 again. The output shaft that drives actuating cylinder 5 withdraws and makes whole jack catch 10 break away from axle type part to can carry out the centre gripping to the axle type and turn to when processing axle type part, reduce axle type part staff's that burns phenomenon, the effectual manpower of having saved has promoted the security of production.
