The utility model aims to provide a valve core bar clamping mechanism of a natural gas valve body, which solves the problems.
The technical scheme adopted by the utility model is that the valve core bar clamping mechanism of the natural gas valve body comprises a frame, wherein the frame comprises a bottom plate, two sliding columns and a top plate;
the cylinder is arranged at the center of the top plate, the sliding plates vertically slide on the two sliding columns, and a pushing block is arranged at the head of a piston rod of the cylinder;
The left side and the right side of the top of the sliding plate are respectively provided with a lower hinging seat;
The left side and the right side of the bottom of the top plate are respectively provided with an upper hinging seat;
the two connecting rods are hinged to the pushing block, the lower hinging seat and the upper hinging seat respectively;
the connecting rod group comprises a first connecting rod, a second connecting rod and a third connecting rod;
the first end of the first connecting rod is hinged to the side face of the pushing block;
the first end of the third connecting rod is hinged to the lower hinge seat;
the second ends of the first connecting rod, the second connecting rod and the third connecting rod are all hinged together;
a supporting block is arranged at the top of the bottom plate;
The lower surface of the sliding plate is provided with a pressing block;
The support block is opposite to the pressing block;
the top of the supporting block and the bottom of the pressing block are both provided with arc sections for being attached to the bar stock.
The beneficial effects are that:
The clamping mechanism utilizes the dead point of the connecting rod to strongly self-lock, clamps the self-locking mechanism, has a simple and ingenious structure, can realize a locking function through one cylinder movement, has the self-locking function, replaces a bench vice on a milling machine workbench to clamp, and is rapid in clamping.
