Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples and be described in detail as follows:
Refer to Fig. 1, the utility model comprise be oppositely arranged, inner edge all has the first clamping plate 5 and the second clamping plate 6 of V-arrangement clip slot, be respectively equipped with integrated first connecting portion 2 and the second connecting portion 7 at the two ends of the first clamping plate 5, be respectively equipped with integrated 3rd connecting portion 4 and the 4th connecting portion 10 at the two ends of the second clamping plate 6, wherein the 4th connecting portion 10 extends formation laterally and grips portion.During use, annular workpieces 11 is placed between the first clamping plate 5 and the second clamping plate 6, by reducing the distance of both the first clamping plate 5 and the second clamping plate 6 gradually, between V-arrangement clip slot annular workpieces 11 being clamped to two clamping plate.
Whole device, as gripping portion, after annular workpieces 11 loading is fixed on this device, is fixed on the workbench of milling machine, machining center by the above-mentioned portion of gripping together with workpiece by the extension of the 4th connecting portion 10.
First connecting portion 2 and the second connecting portion 7 all offer screwed hole, 3rd connecting portion 4 and the 4th connecting portion 10 all offer connecting hole, also comprise be located in the 3rd connecting portion 4 connecting hole in the first trip bolt 3 and the second trip bolt 8 of being located in the connecting hole of the 4th connecting portion 10, the end of the first trip bolt 3 is positioned at the screwed hole of the first connecting portion 2, and the end of the second trip bolt 8 is positioned at the connecting hole of the second connecting portion 7.Above-mentioned first clamping plate 5, second clamping plate 6, first trip bolt 3 and the second trip bolt 8 four form frame structure, by synchronously driving the first trip bolt 3 and the second trip bolt 8 to rotate, realize the adjustment of both the first clamping plate 5 and the second clamping plate 6 distance.
Offer screwed hole at the middle part of the first clamping plate 5, be provided with jackscrew 1 in this screwed hole, the center line of jackscrew 1, first trip bolt 3 and the second trip bolt 8 three is coplanar and parallel to each other.Jackscrew 1 laterally carries out auxiliary jacking to annular workpieces 11 for clamp annular workpieces 11 at both the first clamping plate 5 and the second clamping plate 6 after.
In the present embodiment, for the ease of carrying out turn to jackscrew 1, the outer end of jackscrew 1 is provided with rotating end.In order to lock clamp position, the stability of lifting workpieces in process, on jackscrew 1, first trip bolt 3 and the second trip bolt 8, all locknut is set in the present embodiment.
Outside in the middle part of the second clamping plate 6 is one-body molded V-clevis 9, and this V-clevis 9 is mainly used in gripping of the less annular workpieces of diameter 11.
Fig. 2 and Fig. 3 is respectively the structural representation that this clamping and fixing device grips large-diameter workpiece and small diameter workpiece, can find out: for the annular workpieces 11 that diameter is larger, what mainly play clamping action is the first clamping plate 5 and the second clamping plate 6, and the inner of jackscrew 1 is used for auxiliary clamping; When the annular workpieces 11 needing clamping diameter less, need the second clamping plate 6 to turn direction, namely V-clevis 9 is towards inner side, now as the small diameter workpiece in Fig. 3 falls in the notch of V-clevis 9, coordinates realize fixing with the inner of jackscrew 1.
