Technical field

The utility model is related to clamping devices, and in particular to interior clamping of the one kind based on spiral-toggle series connection force-increasing mechanism Electric fixture.

Background technology

With the development of industry, manipulator is widely used in field of machining.The type of interior clamping manipulator is various, Since the difference of its power perhaps can cause environmental pollution or chucking power not big enough, operation is inconvenient, and inefficiency The shortcomings that.

Utility model content

The purpose of this utility model is to provide one kind with efficient, convenient, green, the high and stable one kind of chucking power Novel interior clamping electric manipulator.

What the technical solution of the utility model was realized in.

Interior clamping electric fixture of the one kind based on spiral-toggle series connection force-increasing mechanism, by pedestal, end cap, motor, shaft coupling Device, nut, toggle, triangle pole, motion bar, support cap, leading screw, spring lever are constituted, and the chassis interior is fixed with motor, described Pedestal is connected with end cap, and the motor is connected by shaft coupling with leading screw, the leading screw and the first oppositely oriented nut and the Two nuts constitute screw pair, first nut and the second nut and are hinged by axis pin with toggle, the toggle length phase Together, link mechanism 7 is constituted, the toggle is hinged by axis pin with triangle pole, and the triangle pole is hinged by axis pin with motion bar, The long side rod of the triangle pole is made up of two parallel four using motion bar as common edge with the motion bar of equal length axis pin The link mechanism 9 of side shape, one section of the spring lever and the hinge joint of two triangle poles are hinged by axis pin, the spring lever it is another The hinge joint of one end and two motion bars being located above is hinged by axis pin, one side that the motion bar is contacted with workpiece and branch It is hinged by axis pin to support cap, when work, when electrical power, shaft coupling drives leading screw rotation, nut to be limited and rotate by end cap, and two A nut does opposite horizontal movement, and the hinge joint of two toggles above nut moves straight up, two below nut The hinge joint of toggle moves straight down, and the hinge joint level of two triangle poles moves downward, based on motion bar and triangle pole group At special link mechanism 9 by inside workpiece firm grip.Pass through the reinforcement of the reinforcement structures in series double leval jib of screw pair Structure amplifies chucking power.

The stability of link mechanism 9 when the soft or hard guarantee of the spring lever adjustable springs does not work.

The axis of the leading screw is overlapped with the axis of workpiece.

The nut is connect with toggle, the equal length of four toggles, ensures the hinge joint vertical and straight movement of toggle.

The length of the motion bar is identical, and intermediate active bar is parallel with the axis of leading screw, is based on link mechanism 9, energy To the upper and lower surface while multipoint clamping of workpiece.

The toggle, triangle pole, motion bar material be aluminium alloy.

The surface that the support cap is contacted with workpiece is equipped with the anti-skid chequer of diamond shape, and material is polyurethane.

When the clamped position of the workpiece is interior cylinder, 3 uniformly distributed secondary toggle-activity bar cramps of circumferencial direction may be used Hold mechanism.

In the presence of the utility model solves the problems, such as technical background, there is following gain effect.

Interior clamping electric fixture of the one kind based on spiral-toggle series connection force-increasing mechanism can pass through manpower hand instead of traditional Work clamping workpiece, have many advantages, such as efficiently, conveniently, chucking power is high, clamping is stablized.
