Abstract
The invention relates to an automatic centering fixture. A hydraulic cylinder and a guide rail are arranged and fixed on a base, the motion direction of the piston rod of the hydraulic cylinder is ensured to be vertical to the guiding direction of the guide rail when in mounting, a forked joint is fixedly connected with the head of the piston rod of the hydraulic cylinder, a pin shaft is utilized to hinge two force arms with the forked joint, two V-shaped chucks of the same type are arranged in the guide slot of the guide rail, a chuck pin shaft is utilized to hinge the two V-shaped chucks with the two force arms respectively, and a change valve is connected with the oil inlet/outlet of the hydraulic cylinder by virtue of a hydraulic pipeline.
Description
Technical field
The present invention relates to a kind of anchor clamps, particularly a kind of automatically centering fixture belongs to the machine tool technical field.
Background technology
In metal cutting processing and other machining, often workpiece centering need be clamped, at present, in the anchor clamps that some centering clamp, there is complex structure, the defective that clamping force is lower, versatility is relatively poor causes certain trouble and inconvenience to production.
Summary of the invention
The objective of the invention is to: a kind of automatically centering fixture is provided, and this automatically centering fixture has simple in structure, and clamping force is higher, versatility advantage preferably.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: install and fix hydraulic cylinder and guide rail on base, the direction of motion of piston rod that guarantees hydraulic cylinder when mounted is vertical with the guide direction of guide rail, forked element is fixedlyed connected with the head of the piston rod of hydraulic cylinder, with bearing pin that two arm of forces and forked element are hinged, two identical V-type chucks are installed in the gathering sill of guide rail, with the chuck bearing pin that two V-type chucks are hinged with two arm of forces respectively, reversal valve is linked to each other with the oil inlet and outlet of hydraulic cylinder through conduit under fluid pressure.
Beneficial effect: among the present invention, because under the effect of hydraulic cylinder piston rod, two arm of forces can be realized synchronously inwardly closing up and outwards separating, so, under the effect of the arm of force, the V-type chuck also just synchronously leaves mutually or draws close in guide-track groove, realizes the purpose that self-centering clamps, adopt hydraulic cylinder as the power that clamps, has bigger clamping force, so the present invention has simple in structure, clamping force is higher, versatility advantage preferably, makes things convenient for the needs of some productions.
Description of drawings
Below in conjunction with accompanying drawing structure of the present invention is described further.
Accompanying drawing is a schematic diagram of the present invention.
