Above-mentioned inclined-plane self-locking manual hold down gag, is characterized in that: described flexible member is reseting plate spring.
Above-mentioned inclined-plane self-locking manual hold down gag, is characterized in that: described bearing is mounted by means of bolts on the upside of described base plate.
Above-mentioned inclined-plane self-locking manual hold down gag, is characterized in that: described flexible member one end is welded on the downside of described mount pad.
Above-mentioned inclined-plane self-locking manual hold down gag, is characterized in that: described flexible member one end is arranged on the downside of described mount pad by screw.
The utility model compared with prior art has the following advantages:
(1) thrust of this inclined-plane self-locking manual hold down gag is far away higher than common manual fixture, can substitute hydraulically operated fixture or air-actuated jaw within the specific limits.
(2) this inclined-plane self-locking manual hold down gag adopts face contact type wedge self-locking mechanism, and self-locking property is good, and vibration resistance is strong.
(3) this inclined-plane self-locking manual hold down gag design is very reasonable, simple and compact for structure, one end that operating personnel only need use hammer to knock slide-bar can realize the compression of workpiece, and the other end using hammer to knock slide-bar can realize unclamping of workpiece, operates very easy.
(4) this inclined-plane self-locking manual hold down gag compact, lightweight, easy accessibility, is convenient to safeguard, long service life is applied widely.
(5) production technology of this inclined-plane self-locking manual hold down gag is simple, and requirement on machining accuracy is not high, and a lot of parts are convenient to produce or buy all very much, and thus its production cost is very low, is convenient to promote the use of.
Below by drawings and Examples, the utility model is described in further detail.

Detailed description of the invention
A kind of inclined-plane self-locking manual hold down gag as depicted in figs. 1 and 2, comprised base plate 1 and the passive bearing 2 of fixation, also comprise for workpiece pressing 7 and side be provided with groove 6-1 wedge pressure head 6, for drive described wedge pressure head 6 compress described workpiece 7 slide-bar 5, for installing the mount pad 4 of described slide-bar 5 and the flexible member 8 for driving described wedge pressure head 6 to pop up, bearing 2 is installed with by bolt 3 on the upside of described base plate 1, described mount pad 4 is welded with on the upside of described bearing 2, slide in described mount pad 4 and be provided with described slide-bar 5, cammed surface 5-1 is provided with on the downside of described slide-bar 5, described mount pad 4 is positioned at immediately below described cammed surface 5-1 and is provided with described wedge pressure head 6, the upper surface of described wedge pressure head 6 is identical with the inclination angle of cammed surface 5-1, the upper surface of described wedge pressure head 6 and the inclination angle scope of cammed surface 5-1 are 5 ° ~ 10 °, preferably 7 °, be fixedly connected with described flexible member 8 one end on the downside of described mount pad 4, described flexible member 8 other end is arranged in described groove 6-1.
In the present embodiment, described flexible member 8 is reseting plate spring, and flat spring is compared with traditional cylindroid helical-coil compression spring, and structure is simple, takes up room less.
In the present embodiment, described bearing 2 is fixedly mounted on the upside of described base plate 1 by bolt 3.
In the present embodiment, described flexible member 8 one end is welded or is arranged on the downside of described mount pad 4 by screw.
The course of work of the utility model inclined-plane self-locking manual hold down gag is: as shown in Figure 2, first this inclined-plane self-locking manual hold down gag is fixed on operating position, workpiece 7 is placed on the downside of wedge pressure head 6, the right side of slide-bar 5 is knocked with hammer, slide-bar 5 slides left in mount pad 4, the cammed surface 5-1 be positioned on the downside of slide-bar 5 is made to compress the upper surface of wedge pressure head 6, thus make wedge pressure head 6 move down workpiece pressing 7, because the upper surface of cammed surface 5-1 and wedge pressure head 6 belongs to the cooperation of self-locking wedge, the long-time workpiece pressing 7 of wedge pressure head 6 can be made.
When workpiece 7 is processed complete after, knock the left side of slide-bar 5 with hammer, slide-bar 5 slides to the right in mount pad 4, and the upper surface of cammed surface 5-1 and wedge pressure head 6 departs from, wedge pressure head 6 moves up under the effect of flexible member 8, thus can take out the workpiece 7 machined easily.
The above; it is only preferred embodiment of the present utility model; not the utility model is imposed any restrictions; every above embodiment is done according to the utility model technical spirit any simple modification, change and equivalent structure transformation, all still belong in the protection domain of technical solutions of the utility model.
