Background technology
Existing eccentric wheel clamping workpiece device adopts common plug location, the positioning relation forming " plane and two pits " is coordinated with common pressing plate, but due to the change in size within the scope of eccentric wheel bearing tolerances, and the factor such as the efficiency of common pressing plate is lower, cause eccentric wheel to occur the dancing of eccentric wheel along alignment pin in " plane and two pits " location, cause eccentric wheel excircle dimension fluctuate large, error is comparatively large, the quality of product is unstable, percent defective is high, and production efficiency is lower.
Summary of the invention
For the deficiency that prior art exists, object of the present invention just there are provided a kind of eccentric wheel Special purpose turning fixture, simple to operate, trade union college is quick, positioning precision is high, workpiece dismounting is quick, part working (machining) efficiency is high, constant product quality, yield rate is high, and this fixture is applicable to batch production.
To achieve these goals, the technical solution used in the present invention is such: a kind of eccentric wheel Special purpose turning fixture, comprise clamp body, plug, collet, eccentric wheel, stage clip, pressing plate, packing ring, lag screw, the left end of described plug is connected with clamp body, right-hand member is socketed in collet; Described collet is arranged in eccentric wheel, and the right-hand member of collet abuts with the left end of stage clip; The right-hand member of described stage clip and the left end of pressing plate abut against; Described lag screw successively through packing ring, pressing plate, stage clip, collet, plug, and is connected with clamp body.
As a kind of preferred version, described packing ring has a U-shaped opening.
As a kind of preferred version, the excircle dimension of described pressing plate is greater than eccentric hole size, and the hole size of pressing plate is greater than the head sizes of lag screw.
As a kind of preferred version, described plug is tapered, and the axis of described collet is provided with the conical through-hole, the radial direction that match with plug and is provided with uniform groove.
As a kind of preferred version, described plug is fixed on clamp body by trip bolt.
As a kind of preferred version, between described clamp body and eccentric wheel, be provided with alignment pin screw.
As a kind of preferred version, described lag screw is soket head cap screw.
Compared with prior art, beneficial effect of the present invention: fixture operation of the present invention is simple, trade union college is quick, positioning precision is high, workpiece dismounting is quick, part working (machining) efficiency is high, constant product quality, and yield rate is high, and is applicable to batch production.

Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
Embodiment:
As Figure 1-5, a kind of eccentric wheel Special purpose turning fixture, comprise clamp body 1, plug 2, collet 3, eccentric wheel 4, stage clip (in component has been installed on, therefore not shown), pressing plate 5, packing ring 7, lag screw 6(right-handed thread), the left end of described plug 2 is connected with clamp body 1, right-hand member is socketed in collet 3; Described collet 3 is arranged in eccentric wheel 4, and the right-hand member of collet 3 and the left end of stage clip abut against; The right-hand member of described stage clip and the left end of pressing plate 5 abut against; Described lag screw 6 successively through packing ring 7, pressing plate 5, stage clip, collet 3, plug 2, and is connected with clamp body 1; As shown in figs 6-8, described plug 2 is tapered, and the axis of described collet 3 is provided with the conical through-hole 31, the radial direction that match with plug 2 and is provided with uniform groove 32, and described plug 2 is fixed on clamp body 1 by trip bolt 8; As shown in Figure 9, alignment pin screw 9 is provided with between described clamp body 1 and eccentric wheel 4; As shown in Figure 10, described lag screw 6 is soket head cap screw.
In the present invention, plug 2 is fixed on clamp body 1 by three trip bolts 8, pressing plate 5 and packing ring 7 are compressed by lag screw 6 and fix, further pressing plate 5 extrudes stage clip (not shown), stage clip extrusion spring chuck 3, under the effect of plug 2, make collet 3 be radially expanded, make eccentric wheel 4 inner hole of workpiece gap eliminate further; Meanwhile, pressing plate 5 overcomes stage clip elastic force and continues mobile, compresses eccentric wheel 4 workpiece end face, eccentric wheel 4 workpiece is made to be fixed on clamp body 1, when clamp body 1 clamping is after scroll chuck, make eccentric wheel 4 excircle of workpiece coaxial with lathe spindle, finally realize the turnery processing of eccentric wheel 4 excircle of workpiece.
As shown in figure 11, packing ring 7 is also provided with between the preferred described lag screw 6 of the present invention and pressing plate 5, described packing ring 7 has a U-shaped opening 71, the excircle dimension of described pressing plate 5 is greater than the hole size of eccentric wheel 4, and the hole size of pressing plate 5 is greater than the head sizes of lag screw 6; During enforcement, when unclamping after lag screw 6 takes off packing ring 7, pressing plate 5 and eccentric wheel 4 cross over stage clip, lag screw 6, under fast fetching and change eccentric wheel 4.
During concrete enforcement, when after spanner dextrorotation lag screw 6, lag screw 6 is with under the internal thread acting in conjunction on clamp body 1, make lag screw 6 packing washer 7, further packing ring 7 clamping platen 5, further pressing plate 5 is by stage clip holddown spring chuck 3, with under the acting in conjunction of plug 2, the diameter of collet 3 increases gradually, the endoporus of eccentric wheel 4 workpiece and the cylindrical gap of collet 3 are slowly diminished, finally eliminate completely, achieve the coaxial positioning of eccentric wheel 4 workpiece and plug 2, pressing plate 5 overcomes stage clip elastic force and continues mobile, under the effect of alignment pin screw 9, final compression eccentric wheel 4 workpiece end face, achieve the Fast Installation of workpiece, when spanner is to anticlockwise lag screw 6, packing ring 7 can under fast fetching, under further pressing plate 5 crosses over stage clip and lag screw 6 fast fetching, plug 2 makes collet 3 after losing extruding force effect, have the ability resiled, collet 3 outside diameter diminishes, and makes the endoporus of eccentric wheel 4 workpiece and the cylindrical of collet 3 form gap, further eccentric wheel 4 workpiece can cross over collet 3, stage clip, lag screw 6, easily takes off from fixture.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
