In Workpiece clamping device on above-mentioned a kind of wire cutting machine tool, described clamping plate comprise orthogonal pressure strip and top board, on described pressure strip, be located on described bolt, described top board can with described workpiece against.
In Workpiece clamping device on above-mentioned a kind of wire cutting machine tool, on described pressure strip, be fixedly installed a balance plate, described balance plate can with described positioning beam upper end against.Orthogonal top board and pressure strip are subject to after the active force of workpiece, can there is certain inclination, make workpiece loosening, arrange after balance plate, balance plate and top board are resisted against respectively on positioning beam and workpiece, and the pressure strip between balance plate and top board is horizontal, nut can tightly be resisted against on pressure strip.
In Workpiece clamping device on above-mentioned a kind of wire cutting machine tool, described balance plate is wedge shape.Balance plate is wedge shape, its small end down with positioning beam against, contact area is less, can ensure against steadily.
Compared with prior art, the utlity model has following advantage:
1, orthogonal top board and pressure strip are subject to after the active force of workpiece, can there is certain inclination, make workpiece loosening, arrange after balance plate, balance plate and top board are resisted against respectively on positioning beam and workpiece, and the pressure strip between balance plate and top board is horizontal, nut can tightly be resisted against on pressure strip.
2, balance plate is wedge shape, its small end down with positioning beam against, contact area is less, can ensure against steadily.
