Clamp for hemispherical valve automatic surfacing equipment and technology thereof

Abstract

The invention discloses a clamp for hemispherical valve automatic surfacing equipment and a technology of the clamp. The clamp comprises a base, wherein a first connecting plate is connected to the top of the base in a sliding mode, grooves are formed in the surface of the first connecting plate, supporting plates are installed on the top of the first connecting plate and located on the side faces of the grooves, and a rotating mechanism is installed on the side faces of the supporting plates. A rotating disc is installed on the top of the rotating mechanism, baffles are installed on the top of the rotating disc, and a lifting mechanism is installed on the inner walls of the baffles. Due to the arrangement of the rotating mechanism, when a first motor drives a first lead screw to rotate, the first lead screw can drive a second lead screw to rotate, and the second lead screw is fixedly connected with the the first lead screw. Due to the fact that threaded grooves which are matched with the corresponding lead screws are formed inside a first sleeve and a second sleeve, when the two lead screws rotate, the two sleeves can be driven to form opposite sliding structures, the two sleeves can drive the rotating disc to form a rotating structure through stress rods in the sliding process, and the rotating disc is rotationally connected with the stress rods.

Description

technical field [0001] The invention relates to the production field of hemispherical valves, in particular to a fixture for automatic surfacing welding equipment for hemispherical valves and a process thereof. Background technique [0002] Hemispherical valve is a new type of valve, which is a new type of product developed to solve the technical problems of two-phase mixed flow media such as solution and mortar. It is easy to settle in the solution process of chemical, petroleum, gas, metallurgy, electronics and other industrial sectors. It provides a reliable control valve in the dilemma of affecting the process due to scaling and precipitation. [0003] Hemispherical valves are one of the most important processes during surfacing welding, but now many hemispherical valves are being surfacing welded. To adjust the seat, we propose a fixture and its process for automatic surfacing equipment for hemispherical valves. Contents of the invention [0004] The purpose of the ...
