The purpose of this utility model is to be to provide a kind of centering type workpiece Quick-clamped frock.In order to solve above-mentioned utility model object, the technical scheme adopting is: a kind of centering type workpiece Quick-clamped frock, comprise eccentric screw and heavy stand nut, described eccentric screw comprises cylindrical screw head and is placed in screw head bottom and coupled threaded shank, in described screw head, be concaved with the non-circular handle hole that drives its rotation, the axis of described handle hole and the axis of threaded shank coincide, and between the axis of handle hole and the axis of screw head, have the eccentric throw of a setting spacing; Described heavy stand nut comprises nut head, offers the heavy stand hole of running through its body in described nut head, and the screw head of described eccentric screw is embedded in this heavy stand hole.
As the further improvement of centering type workpiece Quick-clamped frock, described heavy stand hole is included in the first installing hole in upper and lower arrangement relation and the second installing hole in nut head, the bore dia of described the first installing hole is greater than the bore dia of the second installing hole, described screw head is placed in the first installing hole, and described threaded shank is passed the second installing hole and stretched out from the bottom surface of nut head.The height of described screw head is not more than the degree of depth of the first installing hole.The bore dia of described the second installing hole is greater than the external diameter of threaded shank.Described non-circular handle hole is interior hexagonal configuration.The profile of described nut head is regular hexagon.
Compared with prior art, centering type workpiece Quick-clamped frock of the present utility model, its beneficial effect shows:
1), centering type workpiece Quick-clamped frock, there is the advantages such as convenient, the simple and practical and maintenance cost of compact conformation, flexible operation, processing and fabricating is low.
2), centering type workpiece Quick-clamped frock combines use with auxiliary positioner, can be widely used in the manufacture fields such as machinery, electronics, material, or the field that has clamping to need, easy and simple to handle, quick, flexible.
