Description

Technical Field

[0001] The utility model relates to the technical field of valve body production, and specifically relates to a rotary tooling for valve body production. Background Technique

[0002] The "valve body" is an important component in a valve. Generally, it refers to a part that houses components such as a valve core and a valve stem, and is connected to a pipeline, playing the role of withstanding the medium pressure and controlling the fluid flow. The valve body is made of various materials, such as cast iron, cast steel, stainless steel, etc. Its structure and shape vary according to the type of valve (such as ball valve, gate valve, globe valve, etc.) and the application scenario. In industrial production and pipeline systems, the quality and performance of the valve body play a key role in the reliability and sealing of the entire valve;

[0003] For some existing rotary toolings for valve body production, during valve body production, it is necessary to manually fix the valve body. Then, when the valve body needs to be flipped, the valve body is removed and fixed again;

[0004] Some traditional rotary toolings for valve body production have the following problems: During valve body production, the valve body is not firmly fixed, and the valve body cannot be quickly flipped, greatly reducing the production efficiency of the valve body. Therefore, we propose a rotary tooling for valve body production. Content of the Utility Model

[0017] 2. Rotate the dial. The rotation of the dial drives the threaded rod to rotate. The threaded rod rotates and moves downward along the internal thread inside the internal thread cylinder. The upper fixing clamp moves downward between the sliding columns to fix the valve body. The external bolt is threaded through the threaded hole on the dial and inserted into the jack on the upper surface of the rectangular block to lock the dial. When the second motor operates, the rotation of the rotating shaft on the right drives the rotating shaft on the left to rotate through the valve body. The angle sensor will monitor the rotation angle of the rotating shaft on the left in real time. The angle sensor transmits the detected data to the single-chip microcomputer. The single-chip microcomputer integrates the data, and the second motor will achieve the rotation of the valve body, realizing the fixation of the valve body.
