Abstract
The utility model provides a machine tool fixture. The machine tool fixture comprises a fixture base, a pressing plate arranged opposite to the fixture base and used for locating a work-piece with the fixture base, a locating pin arranged between the fixture base and the work-piece, a double-end stud used for connecting the fixture base and the pressing plate, a nut matched with the double-end stud and used for compacting the pressing plate and a gasket arranged between the pressing plate and the nut. Due to the facts that the fixture base and the double-end stud can limit five degree of freedom (DOF) of the work-piece, the locating pin can limit one DOF of the work-piece and six-point locating principle is accorded, and therefore safe locating of the work-piece can be achieved, production efficiency is improved, labor intensity is reduced and processing quality is good.
Description
Technical field
The utility model relates to a kind of jig.
Background technology
Existing vertical knee and column milling machine need be used anchor clamps man-hour work piece is positioned adding; And Milling Process belongs to interrupted cut; Be prone to produce vibration; The stressed member of fraise jig will have enough strength and stiffness, and the clamping force that clamp mechanism provided should be enough big, and require to have the performance of self-locking merit preferably.Yet present fraise jig does not reach above-mentioned requirements, thereby makes production efficiency low, and crudy is poor, and has improved labour intensity.
Summary of the invention
It is high that the technical problem that the utility model will solve provides a kind of production efficiency, and crudy is good, reduces the jig of labour intensity.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: comprise clamp base; And be oppositely arranged with clamp base, locate the pressing plate of workpiece with clamp base, and be arranged on the alignment pin between clamp base and the workpiece, and be used for the studs of jockey base and pressing plate; And nut that cooperate with studs, that be used for clamping platen, and be arranged on the packing ring between pressing plate and the nut.
Further, said pressing plate is the spiral pressing plate.
Further, said packing ring is an open washer.
Further, said clamp base is provided with the screw that cooperates with studs, and said pressing plate is provided with the through hole that supplies studs to pass.
The jig of the utility model; Because through five frees degree of clamp base and studs restriction workpiece, the one degree of freedom through alignment pin restriction workpiece meets principle of six-point fixing; Make workpiece reach safe location; Can enhance productivity, reduce labour intensity, and crudy be good.
Description of drawings
Fig. 1 is the sketch map of the utility model jig.
The specific embodiment
In the present embodiment, with reference to shown in Figure 1, this jig; Comprise clamp base 6; And 6 that be oppositely arranged with clamp base, locate the pressing plate 4 of workpiece with clamp base 6, and be arranged on the alignment pin 5 between clamp base 6 and the workpiece, and be used for the studs 1 of jockey base 6 and pressing plate 4; And 1 that cooperate with studs, as to be used for clamping platen 4 nut 2, and be arranged on the packing ring 3 between pressing plate 4 and the nut 2.
Wherein, said pressing plate 4 is the spiral pressing plate, and fastening nut 2 is through spiral pressing plate workpiece pressing surface.Said packing ring 3 is an open washer, and open washer acts on clamping force on the workpiece equably, can reduce to clamp distortion; In the time of can preventing that pressing plate 4 from tilting, studs 1 not reason receives the moment of flexure effect and damages.Said clamp base 6 is provided with the screw that cooperates with studs 1, and said pressing plate 4 is provided with the through hole that supplies studs 1 to pass.
The jig of the utility model; Because through five frees degree of clamp base and studs restriction workpiece, the one degree of freedom through alignment pin restriction workpiece meets principle of six-point fixing; Make workpiece reach safe location; Can enhance productivity, reduce labour intensity, and crudy be good.
Below the utility model is done a detailed description; The above is merely the preferred embodiment of the utility model, when not limiting the utility model practical range; Be allly to do impartial change and modify, all should still belong in the utility model covering scope according to the application's scope.
