Abstract
The utility model relates to a self-centering clamp. A hydraulic cylinder and a guide rail are fixedly arranged on a base, one end of the hydraulic cylinder is provided with a piston rod, and a fork-shaped connector, the hydraulic cylinder and the head of the piston rod are fixedly connected; and the fork-shaped connector is provided with a pin shaft, two moment arms and the fork-shaped connector are hinged through the pin shaft, a V-shaped clamping head is arranged in a guide groove of the guide rail and is hinged with the moment arms through a clamping head pin shaft, and a reversing valve is connected with an oil inlet and an oil outlet of the hydraulic cylinder through a hydraulic pipeline. The utility model has the beneficial effects that since the hydraulic cylinder is applied to provide power, large clamping force can be generated, and the use effect is good.
Description
Technical field
The utility model relates to a kind of anchor clamps, and particularly a kind of automatically centering fixture belongs to the machine tool technical field.
Background technology
Often workpiece centering need be clamped in metal machining so that work, at present, the clamping force of centralizer is little, make troubles and inconvenience to production and processing easily.
Summary of the invention
The purpose of this utility model is: a kind of automatically centering fixture is provided, and greatly, therefore the clamping force of this automatically centering fixture can bring the facility in the work.
The utility model realizes that technical scheme that above-mentioned purpose adopted is achieved in that it is to install and fix hydraulic cylinder and guide rail on base, is provided with a piston rod at an end of hydraulic cylinder, and forked element, hydraulic cylinder are fixedlyed connected with the head of piston rod; Forked element is provided with a bearing pin, bearing pin is hinged with two arm of forces and forked element, V-clevis is installed in the gathering sill of guide rail, and is with the chuck bearing pin that the V-type chuck and the arm of force is hinged, and reversal valve is linked to each other with the oil inlet and outlet of hydraulic cylinder through conduit under fluid pressure.
Beneficial effect: the utility model uses hydraulic cylinder as power and clamping force is big, so result of use is good.
