Problems solved by technology
[0005] Therefore, the technical problem to be solved by the present invention is to overcome the need to replace different eccentric disks when the tooling fixtures in the prior art are processing C-shaped spheres with different eccentric distances, so it is necessary to prepare eccentric disks of various specifications. It is impossible to process the corresponding C-shaped spheres, which leads to the technical defect of poor equipment versatility, so as to provide a processing tool that does not need to prepare eccentric discs of various specifications, and can be suitable for processing C-shaped spheres with different eccentric distances only by adjusting the equipment

Embodiment
[0047] This embodiment provides a C-shaped sphere processing tool, such as Figure 1-2 As shown, it includes: a first adjustment structure, which is used to fix the C-shaped ball 40, and can adjust the C-shaped ball 40 up and down along the rotation axis α direction of the C-shaped ball 40; the second adjustment structure, through the bottom plate 30 movably installed on the machine tool, the first adjustment structure is installed on the second adjustment structure, and the second adjustment structure can adjust the first adjustment structure in a direction perpendicular to the rotation axis α direction, Furthermore, the C-shaped sphere 40 is adjusted so that the spherical centerline β of the C-shaped sphere coincides with the rotation centerline of the machine tool.
[0048] In this embodiment, the rotation axis of the C-shaped ball refers to the rotation axis when the operating mechanism drives the C-shaped ball to rotate to open or close the flow channel after the C-shaped...

The invention provides a C-shaped sphere machining tool. The C-shaped sphere machining tool comprises a first adjusting structure and a second adjusting structure, wherein the first adjusting structure is used for fixedly mounting a C-shaped sphere and being capable of adjusting the position of the C-shaped sphere up and down in the rotation axis direction of the C-shaped sphere; and the second adjusting structure is movably mounted on a bottom plate, the bottom plate is suitable for being fixedly mounted on a machine tool, the first adjusting structure is mounted on the second adjusting structure, and the second adjusting structure can adjust the first adjusting structure in the direction perpendicular to the direction of the rotation axis so as to adjust the C-shaped sphere. According tothe C-shaped sphere machining tool, for C-shaped spheres with any different eccentricity, the spherical center line beta of the C-shaped spheres can be coincided with the rotation center line of themachine tool only through continuous fine adjustment of the first adjusting structure and the second adjusting structure, eccentric discs with different specifications do not need to be prepared for the C-shaped spheres with different specifications, and the tool is wide in application range.
Description
technical field [0001] The invention relates to the technical field of C-shaped sphere processing, in particular to a C-shaped sphere processing tool. Background technique [0002] The C-type ball valve is also called the eccentric hemispherical valve, which is opened or closed by rotating the C-type ball. The C-type ball valve has simple structure, easy maintenance, and is not easy to be eroded by the medium. It is widely used in petroleum, chemical industry, urban water supply and drainage and other working conditions that require strict sealing. Before the C-type ball is installed into the ball valve, its hemispherical surface needs to be finely ground to form a sealing surface for sealing. [0003] Chinese patent document CN107363601A discloses a tooling fixture for processing eccentric hemispherical valve balls, which is used to seal the C-shaped sphere without grinding, specifically including a mandrel, which runs through the center of the hemispherical body, and uppe...
