Hydraulic rim clamping hand

The utility model provides a hydraulic rim clamping hand which is characterized by comprising a clamping jaw base and at least two hydraulic clamping jaw mechanisms arranged on the clamping jaw base. The two hydraulic clamping jaw mechanisms are oppositely arranged on the clamping jaw base; the hydraulic clamping jaw mechanism is used for clamping a rim; the hydraulic clamping jaw mechanism comprises an oil injection cavity, a clamping block and a telescopic sleeve piece. The pressure is increased through oil liquid in the oil injection cavity, the two telescopic sleeve pieces are pushed to move in the direction close to each other in the axial direction, and then the rim is clamped on the clamping blocks. The technical problems that an air cylinder serving as a power source cannot meet the use requirement and clamping is unstable are solved, and the production takt is accelerated. And the production efficiency is improved. 本实用新型提供了一种液压轮辋夹手，其特征在于，包括夹爪底座，在夹爪底座上设置的至少两个液压夹爪机构；两个所述液压夹爪机构相对设置于夹爪底座上；所述液压夹爪机构，用于夹持轮辋
