Abstract

A clamping device for quickly clamping an end socket of a pressure vessel belongs to the technical field of low-temperature tank box production tools and comprises a chassis seat, a turntable and a plurality of claws, the chassis seat and the turntable are concentrically arranged, the turntable is rotatably mounted on the chassis seat, an end socket positioning shaft is mounted in the center of the chassis seat, and a driving mechanism for driving the turntable to rotate is mounted on the turntable; a plurality of slideways are installed on the upper surface of the chassis seat in a radioactive mode, the clamping jaws are installed on the slideways, the clamping jaws are provided with guide pin shafts parallel to the slideways, the rotating disc is provided with guide grooves which are matched with the guide pin shafts and pull the clamping jaws to contract in the radial direction, and the end socket positioning shaft is provided with a supporting mechanism for supporting an end socket. The sealing head is clamped and grabbed through the sealing head clamping and grabbing device, welding of lifting lugs and the like is not needed, indentation cannot be caused to the sealing head, the periphery of the whole sealing head is evenly stressed, and the deformation amount of the sealing head is effectively reduced; the device has the characteristics of convenience in operation, safety, reliability and high efficiency.

Description

technical field [0001] The invention relates to the technical field of low temperature tank production tooling, in particular to a clamping device for quickly clamping the head of a pressure vessel. Background technique [0002] In the production process of pressure vessel products, the combination of head and cylinder is very important for assembly. The traditional head assembly needs to use the crane to hoist the head, and the head needs to be welded with the lifting lugs in advance. The head is the main pressure component, and the welding lugs are cut again, which increases the risk of welding defects in the head, and the heat input of the welding will also cause deformation of the head. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a clamping device for quickly clamping the head of a pressure vessel, which can protect the head, reduce the deformation amount, and improve the assembly efficiency, aiming at th...
