Abstract

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.

Description

technical field [0001] The invention relates to a turning fixture, in particular to a turning center fixture of an irregular eccentric valve cover. Background technique [0002] At present, due to its irregular structure and unique shape, the processing of the eccentric valve cover is laborious and laborious. Machining centers are generally used for processing. However, the use of machining centers has the following problems: the surface roughness does not meet the requirements, and the processing time for a single piece is long. Efficiency Low, can not meet the requirements of mass production. When the turning center is used to process the valve cover, when the end face is turned, the structure of the part is irregular and eccentric, and the part rotates unbalanced after being installed in the fixture. It is necessary to overcome the impact on the machining accuracy of the part caused by the unbalance of the fixture during processing. Influence and the program of the turni...
