As shown in fig. 1, the utility model provides a clamping mechanism for processing a valve blank, which comprises a rotating shaft 1 arranged along the horizontal direction, wherein an inner expansion chuck 2 is installed at the right end of the rotating shaft 1, a valve blank 3 to be punched is assembled on the inner expansion chuck 2, the rotating shaft 1 is arranged on a fixed frame through a horizontal adjusting mechanism, and the horizontal adjusting mechanism can drive the rotating shaft 1 to move axially to adjust the position. When the valve blank machining device works, a valve blank 3 to be machined is arranged on the inner expansion chuck 2, and the horizontal adjusting mechanism drives the rotating shaft 1 to move axially to drive the inner expansion chuck 2 to clamp the blank so as to perform subsequent machining.

Referring to fig. 2 and 3, the horizontal adjusting mechanism includes a support sleeve 4, a driving cylinder 5, a pull rod 6 and a first bearing 7, the support sleeve 4 is fixedly mounted on the frame, an inner hole of the support sleeve 4 is arranged along a horizontal direction, and the middle part of the rotating shaft 1 is rotatably mounted in the inner hole of the support sleeve 4 and can slide left and right along the inner hole of the support sleeve 4; the cylinder body of the driving cylinder 5 is hinged to the rack, the piston rod of the driving cylinder 5 is arranged towards the left, one end of the pull rod 6 is hinged to the piston rod of the driving cylinder 5, and the other end of the pull rod 6 is hinged to the rack through a first hinge point 8; first bearing 7 is installed the left part of pivot 1, the inner circle of first bearing 7 with the outer wall fixed connection of pivot 1, the middle part of pull rod 6 is equipped with the lantern ring 9, the lantern ring 9 cover is established the periphery of first bearing 7, be equipped with spacing claw 10 along radially setting inwards on the lantern ring 9, the inboard of spacing claw 10 is equipped with spacing groove 11, the outer lane of first bearing 7 sets up in the spacing groove 11, the groove width size of spacing groove 11 is greater than the thickness of first bearing 7.

The design that the rotating shaft 1 is arranged in the inner hole of the supporting sleeve 4 can ensure the stability of the rotating shaft 1 in the moving process. The structure of the bearing and the limiting claw 10 can drive the rotating shaft 1 to axially move and simultaneously ensure the rotational freedom degree of the rotating shaft 1. When the device works, a piston rod of the driving cylinder 5 extends to drive the pull rod 6 to rotate anticlockwise by taking the first hinge point 8 as a rotation center, so that the limiting claw 10 on the lantern ring 9 is driven to move leftwards, the groove wall at the right end of the limiting groove 11 is contacted with the outer ring of the first bearing 7 and pushes the bearing to move leftwards, and the rotating shaft 1 moves leftwards along with the bearing; the piston rod of the driving cylinder 5 is contracted to drive the rotating shaft 1 to move rightwards. Because the limiting claw 10 rotates by taking the first hinge point 8 as a rotating axis in the movement process, the design of the limiting groove 11 which is larger than the width of the first bearing 7 can avoid interference to the first bearing 7 in the movement process.
