The invention provides a turning center clamp of irregular eccentric valve
deck. The turning center clamp comprises a
flange plate, a positioning mechanism, a clamping mechanism and a balancing weight. The positioning mechanism, the clamping mechanism and the balancing weight are installed on the
flange plate. The positioning mechanism comprises a V-shaped positioning block, a positioning bottom plate, an upper limiting block, a lower limiting block, a movable screw and a first
compression screw. The clamping mechanism comprises a movable pressing block, a second
compression screw and a pressing base. A space where valve
deck parts are placed is formed among the V-shaped positioning block, the upper limiting block, the lower limiting block and the movable pressing block. The valve
deck parts are placed on the positioning bottom plate and located in the middle of the
flange plate. The movable screw, the first
compression screw and the movable pressing block clamp the valve deck parts. The balancing weight is used for balancing the
center of mass of all the parts on the flange plate. The turning center clamp is simple in structure, easy to assemble and disassemble, capable of effectively fixing valve deck parts and low in
machining cost.
