The invention discloses a clamp for drilling of a round nut, and relates to the technical field of machining. The clamp comprises a base, a locating mandrel, a drilling plate and a locking device, wherein the locating mandrel is installed on the base, the drilling plate sleeves the locating mandrel and is installed on the locating mandrel, and the locking device is used for tightly pressing the drilling plate on a workpiece; steps which are used for supporting the workpiece are arranged on the locating mandrel, and a drilling hole is formed in the drilling plate. Compared with the prior art, the clamp has the advantages that locating is accurate, drilling accuracy is high, machining quality is good, operation is easy and convenient, the workpiece disassembling and assembling speed is high, and the machining efficiency is improved substantially.

Description

Round nut drill jig
Technical field
The present invention 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: 1, needs naked eyes centering to aim at during boring, borehole accuracy is low, and crudy is poor; Need carry out line centering to each round nut to be processed, working (machining) efficiency is low.
Summary of the invention
The object of this invention is to provide a kind of round nut drill jig, the problem that the borehole accuracy existed when this fixture can solve existing round nut drill end hole is low and working (machining) efficiency is low.
In order to solve the problem, the technical solution used in the present invention is: this round nut drill jig comprises base, the positioning core axle be installed on described base, be set in bushing plate on described positioning core axle and for described bushing plate being pressed in the locking device on workpiece, described positioning core axle is provided with the step supporting 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: be fitted with lining between described bushing plate and described positioning core axle, and 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 snapped 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 have employed technique scheme, the present invention compared with prior art has following beneficial effect: structure is simple, registration, and 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.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
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, the locating hole 1-1 of plug-in mounting positioning core axle 2 is provided with in the middle part of base 1, positioning core axle 2 is fixedly connected with base 1 by screw 1-2, positioning core axle 2 has the positioning section 2-1 set gradually, axial limiting section 2-2, radial spacing section of 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 and collides base 1 to avoid drill bit, the two ends of this axial limiting section 2-2 form limited step respectively, limited step and the base 1 of one end abut against, the limited step of the other end forms the step supporting workpiece, for limiting radial direction spacing section of 2-3 of workpiece radial position on axial limiting section 2-2, the radial external diameter of spacing section of 2-3 and the internal diameter of round nut 8 match, be the connection shaft part 2-4 that one section of external diameter is less than radial spacing section of 2-2 on this radial direction spacing section of 2-3, 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 and the external diameter connecting shaft part 2-4 of radial direction spacing section of 2-2, bushing plate 3 is provided with boring, for protection boring, extend bushing plate 3 service life, drill bushing 4 is provided with in boring, 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 snapped 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 bushing plate 3 and lining 5 in advance, round nut to be processed cover 8 is loaded on the limited step that positioning core axle 2 makes itself and radial direction spacing section of 2-3 and axial limiting section 2-2 be formed abut against, the connector of lining 5 and bushing plate 3 is inserted on positioning core axle 2, bushing plate 3 is made to be placed on round nut 8 to be processed, 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, lining 5 and bushing plate 3 compress by pressing plate 6 pressurized, thus the round nut 8 that is fixedly clamped.Drilling operation can be carried out after drill bit being aimed at the drill bushing 4 of bushing plate 3, after machining, unclamp bolt, by the side openings of pressing plate 6, pressing plate 6 is taken out, then take out the connector of lining 5 and bushing plate 3, then take out the round nut 8 machined, replace to another round nut to be processed 8, to be fixedly clamped this nut according to above-mentioned steps, to 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.
