For achieving the above object, the technical solution adopted in the utility model is: a kind of rotary drill fixture, comprises alignment pin, positioning sleeve, open washer, nut, locating shaft, workpiece, drill bushing, index dial, handle, lining, knob, clamp body and backing pin; Described locating shaft runs through clamp body and both sides are given prominence to, and embeds alignment pin bottom clamp body, and the two ends of alignment pin install knob and positioning sleeve respectively; Described locating shaft side nut is fixed, and between open washer is set; The inner mounting bush of described clamp body, and be positioned at the surface of locating shaft; One end welding handle of described locating shaft; The top of described locating shaft arranges workpiece, and arranges index dial between workpiece and clamp body; The top of described workpiece arranges drill bushing, and drill bushing is welded on side, clamp body top; Described sleeve surface arranges backing pin.

Further, described drill bushing and workpiece top axle center of being holed to be on same axis and workpiece is fastening by handle.

Further, described open washer diameter is greater than workpiece and is in diameter outside alignment pin.

Further, described workpiece is accurately located by index dial and index dial is set in outside locating shaft.

Further, the T-shaped structure of described clamp body, adopts the foundry goods of integral type.

The beneficial effects of the utility model are: this rotary drill fixture has enough strength and stiffness, structure is simple and workpiece loading and unloading convenient, structural manufacturing process shape is good, chip removal chip will facilitate, lathe is installed reliable and stable, there is suitable precision and dimensional stability, open washer achieves the fast assembling-disassembling of workpiece, improve production efficiency, the setting of index dial, ensure that the Distance geometry angle in three holes on workpiece, nut and open washer not too large with the use of the amount of movement that can ensure about axle, decrease the time of assembling workpiece, can the operation of service new product easily rapidly, to shorten the Operational preparation cycle, reduce production cost, and the workpiece of similarity feature can be had by clamping one group, be applicable to the Novel jig of precision machined high precision machine tool fixture and various modernization manufacturing technology, the efficient clamping device that to adopt with Hydraulic Station etc. be power source, to reduce labor intensity further and to raise labour productivity, improve the standardization level of jig.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.Obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

As shown in Figure 1-2, a kind of rotary drill fixture, comprises alignment pin 1, positioning sleeve 2, open washer 3, nut 4, locating shaft 5, workpiece 6, drill bushing 7, index dial 8, handle 9, lining 10, knob 11, clamp body 12 and backing pin 13; Described locating shaft 5 runs through clamp body 12 and both sides are given prominence to, and embeds alignment pin 1 bottom clamp body 12, and the two ends of alignment pin 1 install knob 11 and positioning sleeve 2 respectively; Described locating shaft 5 side nut 4 is fixed, and between open washer 3 is set; The inner mounting bush 10 of described clamp body 12, and be positioned at the surface of locating shaft 5; One end welding handle 9 of described locating shaft 5; The top of described locating shaft 5 arranges workpiece 6, and arranges index dial 8 between workpiece 6 and clamp body 12; The top of described workpiece 6 arranges drill bushing 7, and drill bushing 7 is welded on side, clamp body 12 top; Described lining 10 surface arranges backing pin 13.

Novel optimisation technique scheme is used: described drill bushing 7 and workpiece 6 top axle center of being holed to be on same axis and workpiece 6 is fastening by handle 9 as this; Described open washer 3 diameter is greater than workpiece 6 and is in diameter outside alignment pin 1; Described workpiece 6 is accurately located by index dial 8 and index dial 8 is set in outside locating shaft 5; The T-shaped structure of described clamp body 12, adopts the foundry goods of integral type.

The utility model in use, when bore hole axis rotates decline, drill bushing 7 plays spacing, fixing effect, now clamp body 12 is stable on the table by bolt, in turn ensure that the reliability of drill bushing 7, workpiece 6 is fixed on clamp body 12 side by locating shaft 5, nut 4 is fastening, open washer 3 prevents from loosening, and locating shaft 5 penetration liner 10, the distance of locating shaft 5 is regulated by handle 9, in conjunction with the display of index dial 8 scale, be convenient to observe, when the distance needed is less, the gap of regulation and localization cover 2 can be come again by knob 11, thus reach the object of index dial 8 fine setting.
