Description
Technical field
The utility model relates to fixture, is specifically related to a kind of circle eccentric clamp.
Background technology
Be used for fixing processing object in machine-building process, make it to occupy correct position, to accept the device of constructing or detecting, also known as jig.Such as weld jig, inspection jig, assembling jig, jig etc., wherein jig is the most common.On lathe during processing work, the dimensions reaching drawing for making the surface energy of workpiece and specify, geometry and with the technical requirements such as the relative-position error on other surfaces, workpiece must be installed before processing, clip.
Along with industrial development, work pieces process gets more and more, and is all Workpiece fixing will be clamped at numerous processing modes, and Workpiece clamping makes there is correct position relative to lathe, cutter during work pieces process, to ensure the machining accuracy of workpiece, jig plays an important role in machining.The position of the clamping point of current eccentric clamp system is constant, and the size of the workpiece of processing fluctuates within the specific limits, and just for a kind of clamping of workpiece, waste can only be caused with a clamp system, also have impact on the accurate of locating and machining simultaneously, cause the quality of workpiece low.
Utility model content
The utility model is intended to provide a kind of circle eccentric clamp, the fixture that can regulate according to the change of workpiece size, and its clamping effect is good, and workpiece quality after processing is high.
The base case that this programme provides is: circle eccentric clamp, and comprise fixed mechanism and driving mechanism, described fixed mechanism comprises pedestal and hold-down screw, and described hold-down screw is fixedly connected in pedestal; Described driving mechanism comprises pressing plate, eccentric wheel, handle, canted tie plate and driving screw, one end and the eccentric wheel of described pressing plate are hinged, the lower surface of the other end is provided with projection, described eccentric wheel is fixedly connected with handle, described driving screw is connected on pedestal, and described canted tie plate is fixedly connected with driving screw; Described pressing plate is provided with hole, and described hold-down screw is through hole, and be provided with upper gasket between the head of described hold-down screw and the upper surface of pressing plate, the lower surface of described pressing plate is provided with lower gasket, is provided with spring part between described lower gasket and pedestal; Described canted tie plate is provided with chute, and described eccentric wheel slides in chute; Described driving screw-driven canted tie plate moves in the horizontal direction of pedestal.
The principle of this programme is: hold-down screw is fixedly connected in pedestal through pressing plate, forces in handle drives eccentric wheel and rotates in the chute of canted tie plate; Owing to being provided with upper gasket between the head of hold-down screw and the upper surface of pressing plate, the lower surface of pressing plate is provided with lower gasket, be provided with spring part between lower gasket and pedestal, eccentric wheel rotates counterclockwise, and band dynamic pressure plate moves down, spring part is in compact state, clamping work pieces, according to the change of workpiece size, drives screw to order about canted tie plate and moves left and right in the horizontal direction of pedestal, otherwise, unclamp workpiece.
The advantage of this programme is: drive screw to order about canted tie plate and move left and right in the horizontal direction of pedestal, force in handle strip movable eccentric wheel to rotate in the counterclockwise direction simultaneously, pressing plate moves down workpiece pressing, spring part is compact state, compare current eccentric clamp system and cause insufficient clamping force because of the change in size of clamping work pieces, this programme is according to the change of workpiece size size, the position of adjustable inclined surface apparatus backing plate and to be eccentricly rotated counterclockwise, effective clamping work pieces processing work, make the quality of workpiece be protected; Otherwise force in handle strip movable eccentric wheel and rotate in the clockwise direction, pressing plate moves up and unclamps workpiece, spring part gives pressing plate one power upwards simultaneously, shortens the time of unclamping.
Preferred version one: based on the preferred version of scheme, the lower surface of described pressing plate is also provided with nut, described nut is arranged between spring part and pedestal, by above-mentioned setting, in the process of clamping work pieces, hold-down screw is connected with base thread and defines hold-down screw position and do not change, then increases a nut and be threaded with hold-down screw, limits hold-down screw position further and does not change.
Preferred version two: based on the another preferred version of scheme, the diameter in described hole is greater than the bar portion diameter of hold-down screw, and by above-mentioned setting, when the diameter in the hole on pressing plate is greater than the bar portion diameter of hold-down screw, pressing plate moves up and down easier; When the diameter in the hole on pressing plate equals the bar portion diameter of hold-down screw, increase contact surface, frictional force increases, and pressing plate moves up and down more difficult.
Preferred version three: based on the another preferred version of scheme, described spring part is pressing spring, and by above-mentioned setting, when workpiece pressing, pressing plate is subject to the downward power of eccentric wheel, and now pressing spring is compact state; When unclamping workpiece, pressing spring changes reset condition into by compact state and gives pressing plate a thrust, shortens the time of unclamping workpiece.
Preferred version four: based on the another preferred version of scheme, described pressing plate by bearing pin and eccentric wheel hinged, by above-mentioned setting, because this programme realizes mainly through pressing plate and eccentric relative motion, the work of bearing pin is more reliable, dismantles more convenient.
