The utility model provides a small-bore valve body up end processing frock, includes: the clamping device comprises a chuck, an upper support, a lower support, a fixed jaw, a movable jaw and a guide rod; the lower support is fixed on the chuck, the fixed jaw is fixed on the upper surface of the lower support, the fixed jaw is cylindrical, and the diameter of the fixed jaw is matched with the inner diameter of the medium inlet/outlet of the valve body; when the position of the fixed jaw is used for clamping the medium inlet/outlet of the valve body on the fixed jaw, the central line of the valve shaft mounting hole is coplanar with the central shaft of the chuck; the movable clamping jaw is of a two-stage ladder cylindrical shape, the diameter of a cylinder on the upper portion is larger than that of a cylinder on the lower portion, the diameter of the cylinder on the lower portion is matched with the inner diameter of a medium inlet/outlet of the valve body, the upper support is fixed on the chuck and located above the lower support, a threaded hole is formed in the upper support, the guide rod is in threaded connection with the threaded hole, the tail portion of the guide rod is rotatably fixed to the top of the movable clamping jaw, the head portion of the guide rod is of a hexagonal structure, and the guide rod.
Preferably, still include the curb plate, the one side of curb plate is fixed upper bracket and undersetting simultaneously, and the curb plate another side is fixed with the chuck.
Preferably, the device also comprises a handle, and the middle part of the handle is provided with a hexagonal hole corresponding to the head part of the guide rod.
Preferably, the chuck is provided with mounting holes through both ends thereof for fixing the chuck to the lathe spindle.
The utility model discloses a frock is the special processing frock of different model valve bodies, during the use, with chuck bolt fastening on the lathe main shaft, will correspond the valve body medium business turn over/export suit of model on fixed jack catch to make the valve body up end outside, other instruments of deuterogamying make the valve body up end adjust well, later rotate the guide bar with the handle, make another medium of the downward chucking valve body of activity jack catch business turn over/export, alright in order to carry out turning and tapping processing. Through this frock, the three axial position of valve body is very easy to be confirmed, so can save time, raise the efficiency to can improve the precision.
