Description
Technical field
The present invention relates to a kind of clamping device, particularly relate to a kind of wedge clamping device.
Background technology
Clamping device is for the clamping between two parts, and for traditional clamping device, for the clamping (with the clamp operation that perforation means carries out) between two parts that Impact direction is in 90 °, clamping force direction causes stretching into spanner class instrument.And the physical dimension of two parts is relatively big, especially more prominent with flat-type part, hands or instrument cannot stretch to clamped position.
For example, for forcing on slide block by oblique roller, the wedge clamping device clamping workpiece with the pressing plate on movable slider moves up and down is suitable only for miniature workpiece, and it is disadvantageous in that the pressing plate arm of force is unsuitable long.Making pressing plate down for screwing with bolt, the wedge clamping device that pressing plate ramp compresses with the laminating of corresponding workpiece slope, it is limited in that pressing plate bevel angle is limited to workpiece slope angle.Widening axial distance between the two thus the Double Oblique Wedge clamping device of Clamp blocks for utilizing two fore-sets in Double Oblique Wedge to move along inclined-plane, it is disadvantageous in that clamping force is not on a straight line, thus can produce moment of torsion.
Summary of the invention
The brief overview of one or more aspect given below is to provide the basic comprehension to these aspects.This summarizes the extensive overview of the not all aspect contemplated, and is both not intended to identify the key or decisive key element also non-scope attempting to define any or all aspect of all aspects.Its some concepts being uniquely intended to provide in simplified form one or more aspect think the sequence of more detailed description given later.
It is an object of the invention to solve the problems referred to above, it is provided that a kind of wedge clamping device, design is light and handy novel, and principle is simple and practical, and clamped contact face is relatively big and gross weight is relatively light, and the number of components of composition is few and processing technology good.
The technical scheme is that and present invention is disclosed a kind of wedge clamping device, grip fastener and fastened part, device includes handle, wedge, fixed mount, fixture, stud, wherein handle is arranged on one end of stud, the other end of stud enters in the slanting wedge hole of wedge through the screwed hole of fixed mount, fixture is arranged in the elongated slot of fixed mount, fixture has inclined-plane square hole, wedge is arranged in the inclined-plane square hole of fixture, the inclined-plane laminating of the inclined-plane of wedge and the inclined-plane square hole of fixture.
One embodiment of the wedge clamping device according to the present invention, device also includes screw and packing ring, and the upper surface of fixture is provided with screw, and screw loads packing ring and screw and tightens screw.
One embodiment of the wedge clamping device according to the present invention, the end face of the end face fastened part of laminating of packing ring, fixture cannot be moved down and be tangled the stud on fixed mount and fixed mount by wedge and stud.
One embodiment of the wedge clamping device according to the present invention, device also includes reed, and one end of reed is fixed on fixed mount, and the other end is positioned at wedge relative to outside the other end of slanting wedge hole.
One embodiment of the wedge clamping device according to the present invention, promote wedge toward moving right when handle is clockwise, under the effect of fixture lower inclined plane, wedge up moves again, up moving until the lower surface laminating locking of upper surface and securing member of fixed mount together with driving fixed mount in the upper plane of wedge under the effect of the stud stretched in slanting wedge hole, the right side actuating spring of wedge is turned right generation elastic force.
One embodiment of the wedge clamping device according to the present invention, when handle is rotated counterclockwise, turn left under the elastic force of reed the promotes drive fixed mount that moves down of wedge moves down together and unclamps the connection of fastened part and securing member.
The present invention contrasts prior art following beneficial effect: wedge clamping device is loaded between securing member and fastened part by the present invention, turning clockwise handle can grip fastener and fastened part, rotating handles counterclockwise can the clamping of loosening fasteners and fastened part, now adjustable fasteners and the mutual position of fastened part.When turn clockwise handle time stud move right, promote wedge toward moving right, under the fixture ramp effect with wedge, fixed mount up moves, and the upper surface of fixed mount and the bottom surface of fastened part are fitted thus playing clamping action.Unclamping rear reed makes wedge reset and be at correct clamped position.
Accompanying drawing explanation
Fig. 1 illustrates the structure chart of the preferred embodiment of the wedge clamping device of the present invention.
Detailed description of the invention
After reading the detailed description that embodiment of the disclosure in conjunction with the following drawings, it is possible to be more fully understood that features described above and the advantage of the present invention.In the accompanying drawings, each assembly is not necessarily drawn to scale, and the assembly with similar correlation properties or feature is likely to be of same or like accompanying drawing labelling.
Fig. 1 illustrates the structure of the preferred embodiment of the wedge clamping device of the present invention.Refer to Fig. 1, the wedge clamping device of the present embodiment includes handle 1, wedge 5, fixed mount 4, fixture 3, stud 2, wherein handle 1 is arranged on one end of stud 2, the other end of stud 2 enters in the slanting wedge hole of wedge 5 through the screwed hole 7 of fixed mount 3, fixture 3 is arranged in the elongated slot of fixed mount 4, fixture 3 there are inclined-plane square hole, wedge 5 are arranged in the inclined-plane square hole of fixture 3, the inclined-plane laminating of the inclined-plane of wedge 5 and the inclined-plane square hole of fixture 3.
Device also includes screw 10 and packing ring 11, and the upper surface of fixture 3 is provided with screw, and screw loads packing ring 11 and screw 10 and tightens screw 10.The end face of the end face fastened part 14 of laminating of packing ring 11, fixture 3 cannot move down and tangle the stud 2 on fixed mount 4 and fixed mount 4 by wedge 5 and stud 2.
Device also includes reed 6, and one end of reed 6 is fixed on fixed mount 4, and the other end is positioned at wedge relative to outside the other end of slanting wedge hole.
Promote wedge 5 toward moving right when handle 1 is clockwise, under the effect of fixture lower inclined plane, wedge 5 up moves again, upper plane at wedge 5 up moves together with fixed mount 4 until the lower surface laminating locking of upper surface and securing member 13 of fixed mount 4 with driving under the effect of the stud 2 stretched in slanting wedge hole, and the right side actuating spring 6 of wedge 5 is turned right generation elastic force.When handle 1 is rotated counterclockwise, turn left under the elastic force of reed 6 the promotes drive fixed mount 4 that moves down of wedge 5 moves down together and unclamps the connection of fastened part 14 and securing member 13.
