By adopting the special drill jig for processing the small row pitch threaded hole, provided by the utility model, hand tapping is not needed, so that the processing efficiency of the small row pitch threaded hole is improved, the processing time is shorten, the labor cost is saved, and the processing quality and processing accuracy are effectively improved.

Description

Be arranged in radial drilling machine machining small apart from the Special drilling jig of screwed hole
Technical field
The utility model relates to drill jig boring in a kind of field of machining, especially a kind of in radial drilling machine machining small apart from the Special drilling jig of screwed hole.
Background technology
In field of machining, for holing, the drill jig of tapping comprises clamp body, be fixed on the bushing plate on clamp body and the drill bushing that is fixed on bushing plate forms.All to fix after workpiece, clamp body and drill jig, first getting out bottom outlet with drill bit, then changing tap tapping, completing the processing of screwed hole to the hole processing on workpiece.The screwed hole smaller for multiple pitchs of holes adds man-hour, bore after the bottom outlet of good each screwed hole, because the pitch of holes between bottom outlet is very little, be easy to damage bottom outlet with the direct tapping of radial drilling machine, cause workpiece to scrap, so generally complete after bottom outlet processing, adopt the method for hand tapping to complete the processing of screwed hole.But not only tapping precision of hand tapping is not high but also be also easy to break at the process plug tap of tapping, affect the whole tapping cycle, tapping efficiency is very low.
Utility model content
Purpose of design: avoid the weak point in background technology, design and be a kind ofly arranged on that in radial drilling machine, machining small is apart from the Special drilling jig of screwed hole, it can effectively improve tapping efficiency, improves machining accuracy.
Design: in order to realize above-mentioned purpose of design.1, being welded with drill bushing and the steel bushing matching design of outer ring, is first technical characterictic of the present utility model.The object of design is like this, welding outer ring, drill bushing top, insert in the locating hole of bushing plate drill bushing bottom, and drill bushing bottom coordinates with the steel bushing grafting being fixed in locating hole, after clamping workpiece is good, put the bottom outlet that drill bushing bores small pitch screwed hole, after having bored bottom outlet, take off drill bushing, can carry out tapping, easy to operate, under the guide effect of steel bushing, small pitch bottom outlet is carried out to tapping and effectively improved Tapping Quality and tapping efficiency.2, the middle circle of drill bushing and the design of edge lug, be second technical characterictic of the present utility model.The object of design is like this, the cross section of drill bushing is made up of middle circle and edge lug, and middle center circular and edge lug all has pilot hole, these two pilot holes are corresponding with two small pitch screwed holes to be processed, circular and edge lug design in the middle of drill bushing, not only improve the accuracy of small pitch hole processing, insert in locating hole drill bushing bottom, due to the effect of lug, improve the positional precision of drill bushing and locating hole, improve the steadiness of drill bushing, avoid drill bushing and locating hole to be offset.3, two drill bushings designs corresponding with drill bit, screw tap respectively, are the 3rd technical characterictics of the present utility model.The object of design is like this, on two drill bushings that coordinate with steel bushing, all have pilot hole, and the pilot hole of two drill bushings is corresponding with drill bit, screw tap respectively, after clamping workpiece completes, put the drill bushing corresponding with drill bit, bore the bottom outlet of two small pitch screwed holes, then change the drill bushing corresponding with screw tap, complete tapping operation.So only need change a drill bushing can complete all drilling and tappings, has greatly improved working (machining) efficiency and crudy, and while preventing hand tapping, the phenomenon of broken tap occurs.4, the inverted T-shaped of steel bushing design is the 4th technical characterictic of the present utility model.The object of design is like this, steel bushing is inverted T-shaped, steel bushing bottom is that boss and the boss external diameter that extends bushing plate is greater than locating hole external diameter, on boss, have coaxial with pilot hole and with screw tap corresponding tapping pilot hole, complete and bore after bottom outlet operation, only need take off drill bushing, can carry out tapping operation to bottom outlet by the effect of tapping pilot hole on steel bushing and steel bushing, effectively shorten process time, improved working (machining) efficiency and crudy.
Technical scheme: a kind of machining small that is arranged in radial drilling machine is apart from the Special drilling jig of screwed hole, the external diameter that an outer ring and outer ring are welded in drill bushing top is greater than the aperture of locating hole on bushing plate, drill bushing bottom be fixed on steel bushing in locating hole and peg graft and coordinate.
The utility model compared with background technology, the one, do not need hand tapping, improved the efficiency of small pitch hole processing, shorten process time, save cost of labor; The 2nd, effectively improve crudy and machining accuracy.
