In order to achieve the above purpose, the self-centering chuck device provided by the invention comprises a pipeline flange provided with a standard alignment pipe section and a chuck assembly sleeved on the pipeline of the pipeline flange, and is characterized in that: the chuck assembly comprises a positioning screw, a chuck body and movable claws; the chuck body consists of a chuck and a sleeve, one end of the sleeve is sleeved outside the standard straight pipe section, the other end of the sleeve is connected with the chuck, and a boss is arranged on the outer wall of the sleeve; the two ends of the claw driving rod are respectively hinged with the boss and the movable claw; the chuck is provided with a clamping groove for accommodating the movable clamping jaw; the sleeve is provided with a positioning hole, and the positioning screw is connected with the positioning hole.
Preferably, the chuck assemblies are symmetrically arranged at the same horizontal section center of the outer wall of the sleeve.
Further, the chuck assembly is provided with 3-6.
Further, the positioning screw is a butterfly screw for fixing the sleeve on the standard alignment pipe section by threads.
Further, the movable claw is of an L shape.
Further, the claw end of the movable claw is provided with a rubber gasket.
The invention has the advantages that: the centering function of the chuck on the threaded connection flowmeter is achieved by utilizing the four clamping jaws in linkage, the clamping jaw driving rod is simple to operate, different types and outer diameters of flowmeters can be adapted in a certain range, the installation operation is simplified, and the verification efficiency is improved.
