Description

Technical Field

[0001] The utility model relates to the technical field of ball valve component processing and positioning, in particular to a clamping tool for valve ball production. Background Art

[0002] The valve ball usually refers to the key component of the ball valve - the ball. A ball valve is a valve that controls the flow of fluid by rotating the ball. It is widely used in various pipeline systems and is known for its easy operation, good sealing, and high pressure resistance. As the core component of the ball valve, the valve ball determines the main performance and service life of the ball valve. During the grinding and spraying process of the valve ball, the corresponding clamping tooling is required to position the valve ball.

[0003] Existing clamping tools for valve ball production mostly use triangular chucks to clamp the outer surface of the valve ball during the actual positioning of the valve ball. Although this clamping method can achieve the positioning of the valve ball, the blocked area of ​​the valve ball often cannot accept sufficient spraying and polishing. The valve ball needs to be disassembled and re-polished and sprayed in the blocked area, resulting in low valve ball processing efficiency. Utility Model Content
