Description

Technical Field

[0001] This utility model relates to the field of ball valve processing technology, specifically a ball valve processing and polishing device. Background Technology

[0002] A ball valve is a valve in which the valve stem drives the valve's opening and closing mechanism, causing it to rotate around the valve's axis. It can also be used for fluid regulation and control. Hard-seal V-type ball valves, in particular, have a strong shearing force between the V-shaped ball core and the metal seat with hard alloy overlay, making them especially suitable for media containing fibers, small solid particles, etc. During the manufacturing process of ball valves, to improve their appearance, the surface needs to be machined and polished, thus requiring the use of appropriate ball valve machining and polishing equipment.

[0003] The patent application CN222307978U discloses a ball valve core surface turning and polishing device, which includes a base, a bracket fixedly connected to the surface of the base, a movable component on the surface of the base for driving the placement seat to move, a stabilizing mechanism on the surface of the placement seat for stabilizing the ball valve core, and a linkage mechanism in the inner cavity of the bracket for simultaneous turning and polishing. This allows the ball valve core to first contact the turning machine for turning, and then contact the polishing machine for polishing.

[0004] However, the above-mentioned device still has the following problems during implementation:

[0005] 1. The existing ball valve processing and polishing device still has some shortcomings in use. After polishing the surface area of ​​the ball valve, there are many impurities left on the surface of the worktable, which makes it difficult to unload the material. The accumulation of a lot of debris is time-consuming to clean up later. In addition, too much large dust and debris may adhere to the surface of the ball valve body, which can easily produce more scratches during polishing.

[0006] 2. Most existing ball valve processing and polishing devices are set as fixed clamping components. The ball valve body surface is arc-shaped. The existing structure is not convenient for adjusting and adapting the positioning of ball valve bodies of various sizes. At the same time, it lacks a ball valve body rotation assist structure during polishing, which is not convenient for rapid multi-angle polishing and has low work efficiency. Utility Model Content
