Machining and assembling device for large-caliber ultralow-temperature high-pressure metal sealing butterfly check valve

Abstract

The invention discloses a machining and assembling device for a large-caliber ultralow-temperature high-pressure metal sealing butterfly check valve. The machining and assembling device for the large-caliber ultralow-temperature high-pressure metal sealing butterfly check valve comprises a base, a first auxiliary fixing assembly, an infrared receiver, a U-shaped plate, a detection mechanism, a drawing box and a control box, a first supporting plate is fixedly arranged on the upper side of the base, a connecting supporting plate is fixedly arranged on the upper side of the base, a first mechanical arm, a second mechanical arm, a third mechanical arm and a fourth mechanical arm are fixedly arranged on the lower side of the connecting supporting plate, a positioning shaft clamping framework is located on the upper side of a third electric telescopic rod, and a hinge clamping mechanism is fixedly arranged on the lower side of the third mechanical arm. According to the machining and assembling device for the large-caliber ultralow-temperature high-pressure metal sealing butterfly check valve, limiting and automatic feeding can be carried out on a butterfly check valve shell, automatically assembling can be carried out on the butterfly check valve, accurate positioning and fixing can be carried out on the butterfly check valve shell, the butterfly check valve can be directly moved out of an assembling table after being assembled, the butterfly check valve can be directly moved out of a assembly table after being assembled, and therefore the advantage that manual carrying is not needed is achieved.

Description

technical field [0001] The invention relates to the technical field of check valves, in particular to a processing and assembling device for a large-diameter ultra-low temperature and high pressure metal-sealed butterfly check valve. Background technique [0002] Butterfly check valve refers to the valve that relies on the flow of the medium itself to automatically open and close the disc to prevent the backflow of the medium, also known as check valve, one-way valve, reverse flow valve, and back pressure valve. The check valve is a kind of automatic valve, its main function is to prevent the reverse flow of the medium, the reverse rotation of the pump and the drive motor, and the discharge of the container medium. Check valves are also used on lines that supply auxiliary systems where the pressure may rise above system pressure. Check valves can be mainly divided into swing check valves (rotating according to the center of gravity), lifting check valves (moving along the a...

Problems solved by technology

[0004] The purpose of the present invention is to provide a large-diameter ultra-low temperature and high-pressure metal-sealed butterfly check valve processing and assembly device to solve the problem that the existing butterfly check valve processing and assembly proposed in the above background technology is mostly transported to the assembly station manually. It cannot be loaded independently, and it needs to be assembled manually. When a human is the team leader, the assembly time is longer, the labor cost is high, and the production cost is increased. At the same time, the material cannot be unloaded directly after the assembly is completed, and manual operation is required, which is inconvenient to use. The problem of poor practicality
