Above-mentioned wedge self-locking double compressing fixture, it is characterized in that: described drive unit is linear electric motors.
Above-mentioned wedge self-locking double compressing fixture, it is characterized in that: described boosting lever is hinged on the fulcrum.
Above-mentioned wedge self-locking double compressing fixture, it is characterized in that: described roller one and described roller two all are hinged on the boosting lever.
The utility model compared with prior art has the following advantages:
(1) this wedge self-locking double compressing fixture can be realized alternately processing of double, and process time and lay day overlap, thereby production efficiency is significantly improved.
(2) this wedge self-locking double compressing fixture has boosting lever, has lever boosting mechanism, can significantly reduce the driving power of drive unit.
(3) this wedge self-locking double compressing fixture adopts Wedge mechanism, has auto-lock function, and drive unit is quit work, and energy-saving effect is remarkable.
(4) this wedge self-locking double compressing fixture is reasonable in design, simple in structure, and operating personnel only need workpiece is placed on the workbench, and these anchor clamps can be finished clamp operation automatically, use very easy.
(5) this wedge self-locking double compressing fixture good rigidly, long service life, the scope of application is extensive.
(6) a lot of parts of this wedge self-locking double compressing fixture all are convenient to produce, buy very much, thereby 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.

The specific embodiment
A kind of wedge self-locking double compressing fixture as shown in Figure 1 comprises drive unit 1 and boosting lever 3, and described drive unit 1 is linear electric motors.Described drive unit 1 end is provided with boosting piece 2, described boosting piece 2 middle parts are provided with vertical slot one 2-1, described boosting lever 3 upper ends and middle part all are rotatablely equipped with roller 1 and roller 29, described roller 1 is arranged in vertical slot one 2-1, and vertical slot one 2-1 and roller 1 are used the problem that can solve boosting lever 3DOF deficiency well.Described roller 29 is arranged in vertical slot two 5-1 at double-side oblique-wedge 5 middle parts, and vertical slot two 5-1 and roller 29 are used the problem that can solve boosting lever 3DOF deficiency well.Described boosting lever 3 lower ends are rotatably installed on the fulcrum 4, and boosting lever 3 has the reinforcement function, can significantly reduce the driving power of drive unit 1.Described double-side oblique-wedge 5 downsides are symmetrically arranged with two wedge pressure heads 6 that are used for workpiece pressing 10 that are mated, and double-side oblique-wedge 5 and wedge pressure head 6 are used has auto-lock function, and drive unit 1 is quit work, and energy-saving effect is remarkable.Two described wedge pressure head 6 downsides are provided with back-moving spring 7, and back-moving spring 7 can make the wedge pressure head 6 that is positioned at non-machining position lift automatically, is convenient to unload the workpiece 10 that machines.
As shown in Figure 1, described boosting lever 3 is hinged on the fulcrum 4.
As shown in Figure 1, described roller 1 and described roller 29 all are hinged on the boosting lever 3.
The course of work of the utility model wedge self-locking double compressing fixture is: at first this wedge self-locking double compressing fixture is installed in the operating position, workpiece to be processed 10 is placed on the processing platform of right side, start drive unit 1, the promotion boosting piece 2 of drive unit 1 moves right, intermediation by roller 1, boosting lever 3 clockwise rotates around fulcrum 4, intermediation by roller 29, double-side oblique-wedge 5 moves right, right side wedge pressure head 6 moves downward under the effect on inclined-plane, double-side oblique-wedge 5 right side, thereby compress right side workpiece to be processed 10, after this just can carry out machining to workpiece to be processed 10, because the clamp mechanism that double-side oblique-wedge inclined-plane, 5 right side and right side wedge pressure head 6 are formed has auto-lock function, and drive unit 1 is quit work, energy-saving effect is obvious.In this simultaneously, left side wedge pressure head 6 moves upward under the effect of left side back-moving spring 7, thereby unclamps the workpiece 10 that the left side has machined.
