The utility model discloses a round-nut drilling fixture and relates to the technical field of machining. The round-nut drilling fixture comprises a base, a positioning mandrel arranged on the base, a drill plate and a locking device, wherein the drill plate is arranged on the positioning mandrel in a sleeved mode, and the locking device is used for compressing the drill plate to a workpiece. A step supporting the workpiece is arranged on the positioning mandrel, and drilled holes are formed in the drill plate. Compared with the prior art, the round-nut drilling fixture is precise in positioning, high in drilling precision, good in machining quality and easy and convenient to operate and substantially improves machining efficiency, and the workpiece can be quickly disassembled or assembled.
Description
Technical field
The utility model relates to Machining Technology field, especially a kind of round nut drill jig.
Background technology
The boring method of existing round nut end face is line centering on the end face of round nut, then round nut is placed on the workbench of drilling machine, make drill bit aim at line centering place and carry out punching, there is following deficiency in this technical scheme: while 1, boring, needs naked eyes centering to aim at, borehole accuracy is low, and crudy is poor; Need be to the centering of ruling of each round nut to be processed, working (machining) efficiency is low.
Utility model content
The purpose of this utility model is to provide a kind of round nut drill jig, the low and low problem of working (machining) efficiency of borehole accuracy that this fixture exists can solve existing round nut drill end hole time.
In order to address the above problem, the technical solution adopted in the utility model is: this round nut drill jig comprises base, be installed on positioning core axle on described base, be set in bushing plate on described positioning core axle and for described bushing plate is pressed in to the locking device on workpiece, on described positioning core axle, be provided with the step that supports described workpiece, described bushing plate is provided with boring.
In the technical scheme of above-mentioned round nut drill jig, technical scheme can also be more specifically: between described bushing plate and described positioning core axle, be fitted with lining, described lining is fixedly connected with described bushing plate by screw.
Further, described locking device comprises pressing plate and clamping screw, and described clamping screw is connected with described positioning core axle through described pressing plate.
Further, described pressing plate has the projection snapping in described lining, the side openings of described pressing plate.
Further, in described boring, drill bushing is installed.
Further, described base is provided with the locating hole of positioning core axle described in plug-in mounting, and described base through screws is fixedly connected with described positioning core axle.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect: simple in structure, and registration, borehole accuracy is high, and crudy is good, simple to operation, and dismounting work speed is fast, has increased substantially working (machining) efficiency high.
Accompanying drawing explanation
Fig. 1 is the structural representation of this round nut drill jig.
The specific embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail:
Round nut drill jig shown in Fig. 1 mainly comprises base 1, positioning core axle 2, bushing plate 3 and locking device, positioning core axle 2 is installed on base 1, base 1 middle part is provided with the locating hole 1-1 of plug-in mounting positioning core axle 2, positioning core axle 2 is fixedly connected with base 1 by screw 1-2, positioning core axle 2 has the positioning section 2-1 setting gradually, axial limiting section 2-2, radially spacing section 2-3 be connected shaft part 2-4, positioning section 2-1 is plugged in the locating hole 1-1 of base 1, axial limiting section 2-2 has enough length to avoid drill bit collision base 1, the two ends of this axial limiting section 2-2 form respectively limited step, the limited step of one end and base 1 connect, the limited step of the other end forms the step of supporting workpiece, on axial limiting section 2-2, be the radially spacing section 2-3 that limits workpiece radial position, the internal diameter of the external diameter of radially spacing section 2-3 and round nut 8 matches, on this radially spacing section 2-3, be the connection shaft part 2-4 that one section of external diameter is less than radially spacing section 2-2, bushing plate 3 is set on the connection shaft part 2-4 of positioning core axle 2, the size in the axis hole aperture of bushing plate 3 is between the external diameter of radially spacing section 2-2 and the external diameter of connection shaft part 2-4, bushing plate 3 is provided with boring, for protection boring, extend 3 service lifes of bushing plate, in boring, be provided with drill bushing 4, bushing plate 3 is fitted with lining 5 with being connected between shaft part 2-4, and lining 5 has the flanging of bending, and lining 5 is fixedly connected with bushing plate 3 by screw 5-1, locking device comprises pressing plate 6 and clamping screw 7, and clamping screw 7 is connected with positioning core axle 2 through pressing plate 6, for the ease of location, pressing plate 6 has the projection snapping in lining 5, and the side openings of pressing plate 6, to carry out fast assembling-disassembling.According to the needs of processing, replaceable different positioning core axle 2 and bushing plate 3.
Before processing, positioning core axle 2 is mounted on base 1, again base 1 is fixedly installed on the workbench of drilling machine, be fixedly connected with in advance bushing plate 3 and lining 5, round nut cover 8 to be processed is loaded on positioning core axle 2 itself and the limited step that radially spacing section 2-3 and axial limiting section 2-2 form are connected, the connector of lining 5 and bushing plate 3 is inserted on positioning core axle 2, bushing plate 3 is placed on round nut to be processed 8, the protuberance of pressing plate 6 is inserted in lining 5, clamping screw 7 is connected with positioning core axle 2 through pressing plate 6, tighten clamping screw 7, pressing plate 6 pressurizeds compress lining 5 and bushing plate 3, thereby be fixedly clamped round nut 8.After drill bit being aimed to the drill bushing 4 of bushing plate 3, can carry out Drilling operation, after machining, unclamp bolt, side openings by pressing plate 6 is taken out pressing plate 6, then take out the connector of lining 5 and bushing plate 3, then take out the round nut 8 machining, replace to another round nut to be processed 8, according to above-mentioned steps this nut that is fixedly clamped, carry out the bore operation of next round.This round nut drill jig simple to operate, convenient mounting and clamping, working (machining) efficiency is high, and borehole accuracy is high, and crudy is good.
