Description

Technical Field

[0001] The utility model relates to the technical field of valve body processing, in particular to a valve body fixing fixture. Background Art

[0002] With the development of machining technology, fixtures have become an indispensable part of machining. At present, fixture technology is developing in the direction of being general, efficient, accurate, intelligent, and environmentally friendly. A fixture is a device used to fix a workpiece during the machining and manufacturing process, so that it occupies the correct position to receive construction or inspection. Fixtures are widely used in industrial production.

[0003] During the process of machining and manufacturing a pipeline valve body, each large hole on each surface is machined one by one using a lathe. When a factory machines the large holes of a pipeline valve body, it is necessary to fix the pipeline valve body in a numerically controlled lathe. Due to the specific shape of the pipeline valve body, it is very difficult to have a suitable fixture to fix it. Therefore, there is an urgent need to develop a suitable tooling that can fix the valve body of the valve to facilitate lathe machining. Summary of the Utility Model

[0014] Preferably, an assembly groove is formed at the bottom of the pallet.

[0015] Advantageous effects: The assembly and fixation of the first support post and the second support post are facilitated by forming the equipment groove at the bottom.

[0016] Preferably, a fixed ring groove is formed on the pallet. A fixed convex ring is arranged on one side of the pipeline valve body. The fixed convex ring is arranged in the fixed ring groove.

[0017] Advantageous effects: By forming the fixed ring groove on the pallet, when the pipeline valve body is clamped, the fixed convex ring can be limited in the fixed ring groove, and the fixation is more firm.
