Abstract
The invention discloses a clamp which has compact structure and high clamping strength and precision. The clamp comprises a pedestal, a fixed clamp jaw base and a movable clamp jaw base. The fixed clamp jaw base is fixed on the pedestal; the movable clamp jaw base is movably arranged on the pedestal; a fixed clamp jaw body is arranged on the fixed clamp jaw base; a movable clamp jaw body which matches with the fixed clamp jaw body is arranged on the movable clamp jaw base; a screw rod adjusting device is arranged in the pedestal; a piston cavity is arranged in the movable clamp jaw base; a piston is arranged in the piston cavity, and the piston cavity is divided into a front oil cavity and a rear oil cavity by the piston; two oil channels which are respectively communicated with the front oil cavity and the rear oil cavity are arranged in the movable clamp jaw base; oil pipe joints are arranged at the oil channels; one side of the piston is provided with a piston rod; and the piston rod is connected with the screw rod adjusting device. The clamp adopts internally-mounted oil cylinder, thereby having very compact structure. In addition, the clamp can clamp the workpiece tightly without supporting the internally-mounted oil cylinder by adopting a long guiding rod. Moreover, the point of the application of the hydraulic force is close to the jaw of the clamp, thus the clamp has higher clamping strength and precision.
Description
Technical field
The present invention relates to a kind of clamp, refer more particularly to a kind of clamp with oil cylinder pushing.
Background technology
At present, traditional clamp with oil cylinder pushing, employing be the plug-in structure of finished product oil cylinder, oil cylinder needs long guide rod and more connector to be connected with movable clamp port body in the clamp, drive movable clamp port body moves forward and backward with respect to deciding the jaw body.Like this, just so that the volume of whole clamp is too huge, clamping dynamics and precision all descend greatly; And, in some equipment that originally structure can be done very compact, for this clamp is installed, and have to increase volume, not only make whole equipment seem relatively heavier, and, also increased manufacturing cost.
Summary of the invention
Technical problem to be solved by this invention is: a kind of compact conformation is provided, and can improves the clamp of clamping dynamics and precision.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of clamp, comprise: base, be fixed on deciding jaw seat and being slidingly arranged in movable clamp port seat on the base on the base, decide to be provided with on the jaw seat and decide the jaw body, be provided with on the movable clamp port seat and the movable clamp port body of deciding the jaw body and matching, be provided with the screw mandrel adjusting device in the base, be provided with plunger shaft in the movable clamp port seat, be provided with piston in the plunger shaft, before piston is separated into plunger shaft, rear oil pocket, also be provided with two in the movable clamp port seat respectively with front, the oil duct that rear oil pocket communicates, the opening part of oil duct is provided with oil connection, one side of piston is provided with piston rod, and this piston rod links to each other with the screw mandrel adjusting device.
The concrete set-up mode of described screw mandrel adjusting device is: be provided with pilot hole in the described base, be movably set with screw mandrel and adjustment seat in the pilot hole, the bottom of adjustment seat links to each other with described piston rod, one end of screw mandrel is arranged in the adjustment seat by screw thread, the other end of screw mandrel is movably arranged on the base by bearing, this end stretches out from bearing, is provided with adjusting handle.
Be provided with a pair of guide rail that is parallel to each other on the described base, be respectively arranged with gathering sill on this outer lateral side to guide rail, the two bottom sides of described movable clamp port seat offers respectively the chute that matches with guide rail and the guide pad that matches with gathering sill.
The described guide rail side of being rail, described chute is rectangular channel.
The invention has the beneficial effects as follows: the present invention has adopted built-in oil cylinder, so that the structure of whole clamp is very compact, and built-in oil cylinder need not grown guide rod supports can be with Workpiece clamping, and the most close jaw of action of hydraulic force point has improved clamping dynamics and precision greatly.In addition, square rail has further improved clamp precision so that the movement of movable clamp port seat is more straight stable.
