The utility model aims at providing a part clamping frock has just been designed in order to solve above-mentioned problem.

The utility model discloses a following technical scheme realizes above-mentioned purpose:

the part clamping tool is used for fixing the pipe joint and comprises a chuck, a fixing piece used for fixing the first end of the pipe joint and a positioning piece used for positioning the pipe diameter center of the second end of the pipe joint, the pipe joint is an L-shaped joint or a three-way joint, and the fixing piece and the positioning piece are both installed on the chuck.

Furthermore, the positioning piece is a positioning piece, the upper end of the positioning piece is of a V-shaped structure, a sliding groove is formed in the upper end of the chuck, and the positioning piece is fixedly installed in the sliding groove.

Furthermore, the locating piece comprises two clamping jaws, the fixing action ends of the two clamping jaws are relatively fixedly installed on the chuck, and the opposite side faces of the two clamping jaws are in compression contact with the outer side wall of the first end of the pipe joint.

Further, the opposite side surfaces of the two clamping jaws are of V-shaped structures.

The beneficial effects of the utility model reside in that: the pipe diameter center of the second end of the pipe joint can be positioned by the V-shaped structure designed at the upper end of the positioning block, and the first end of the pipe joint is fixed by the clamping jaws, so that the purpose of fixing and aligning the center position of the adjacent pipe diameter of a part is realized, and the pipe diameter centering device is simple in structure and convenient to operate.
