Abstract

The utility model relates to a drilling positioner for processing coaxial blind holes or through holes. The drilling positioner can be used for more conveniently and accurately processing the coaxial blind holes or through holes. The drilling positioner comprises a bottom plate and a regulating plate, the bottom surface of one side of the bottom plate is fixedly provided with a nut, and a bolt matched with the nut, the bottom of a screw of the bolt is provided with a blind hole, a fixed pin is arranged in the blind hole, the top surface of the other side of the bottom plate is fixedly provided with at least two guide rods; and one side of the regulating plate is provided with at least two through holes, the through holes and the guide rods on the bottom plate correspond in positions and quantity, the regulating plate can slide up and down along the guide rods through the through holes, the other side of the regulating plate is provided with another through hole, a drilling sleeve is arranged in the through hole, and the through hole and the blind hole on the bottom of the screw are kept coaxial. The fixed pin and a hole to be drilled are integrally coaxial, and thus the principle of positioning the hole to be drilled is improved, the working accuracy of a drill positioner is ensured and the working efficiency is improved.

Description

The boring locator

Technical field

The utility model relates to a kind of mechanical processing and positioning device, relates in particular to a kind of boring locator of processing coaxial blind hole or through hole.

Background technology

In mechanical processing process; The manufacture field that particularly needs working axiality blind hole or through hole, the two ends of drilled object drill through the hole and are difficult to guarantee axiality, that is to say; Two blind holes after the processing are difficult to guarantee coaxial; Perhaps a side of drilled object has had a through hole, need and get through with it at an other STH, and this also need hole coaxial with the blind hole of an other side.Particularly in the part process of various large-scale, the complex contours of processing,, bore the coaxial aperture unusual difficulty that all becomes in its two sidetrackings coaxial aperture or line because of the reason of part self.

The utility model content

The utility model aims to provide a kind of convenient, processes the boring locator of coaxial blind hole or through hole exactly.

In order to address the above problem; The utility model provides a kind of boring locator, comprising: base plate is fixed with nut in a side bottom surface of base plate; One with the supporting bolt of said nut; The screw rod bottom of this bolt offers blind hole, is provided with a steady pin in this blind hole, and the end face of the opposite side of said base plate is fixed with at least two guide rods; Adjustable plate; Side at adjustable plate offers at least two through holes; The position and the quantity of the guide rod on said through hole and the said base plate adapt, and this adjustable plate can slide up and down along guide rod via through hole, and an other side of said adjustable plate offers through hole; Be provided with drill bushing in this through hole, said through hole keeps coaxial with the blind hole of said screw rod bottom.

For make adjustable plate can be better, the more stable guide rod on base plate slides up and down, the boring locator of the utility model wherein, is provided with slip cap in the through hole.

In order to make a plurality of guide rod structures more firm, and adjustable plate can not come off from the guide rod end when sliding, and more preferably, the end of said guide rod is provided with connecting plate.

When carrying out bore operation, be fixed between adjustable plate and the base plate in order to bore thing, preferably, said adjustable plate is provided with magnet.More preferably, said magnet is embedded in the adjustable plate, and is positioned at a side of the through hole on the adjustable plate.

The boring locator of the utility model, adjustable plate can slide up and down, and can adapt to difform drilled object; This locator is through being provided with a steady pin on base plate; This steady pin be integrally formed by the boring nature coaxial, during work, because the blind hole bottom steady pin and the drilled object is coaxial; Thereby the blind hole that has guaranteed the drilled object bottom also keeps coaxial with the blind hole that the top is offered; Improved boring positioning principle, guaranteed the operating accuracy of drilling tool locator, also improved operating efficiency simultaneously.

Description of drawings

Fig. 1 is the structural front view of the boring locator of the utility model;

Fig. 2 is the structural perspective of the boring locator of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing this is practically done further explanation.

In conjunction with Fig. 1 and Fig. 2; The boring locator of the utility model comprises: a base plate 10, be fixed with nut 2 in a side bottom surface of base plate 10, and supporting on this nut 2 bolt 1 is installed; This bolt 1 comprises screw rod and nut; The screw rod bottom offers blind hole 11, is plugged with a steady pin 3 in this blind hole 11, and the diameter of this steady pin 3 is selected according to the diameter of the blind hole that the bottom of being bored thing is offered in advance.The opposite face of the opposite side of said base plate 10, promptly end face is fixed with at least two guide rods 7, is preferably two guide rods here.This boring locator also comprises an adjustable plate 6; Side at adjustable plate 6 offers at least two through holes 12; Here also be preferably two through holes, the position and the quantity of the guide rod 7 on said through hole 12 and the said base plate 10 adapt, and are provided with slip cap 8 in the through hole 12; Guide rod 7 passes through hole 12, and this adjustable plate 6 can slide up and down along guide rod 7 via through hole 12.The end of said guide rod 7 is provided with connecting plate 9, and this connecting plate 9 location guides 7 and making when adjustable plate 6 slides up and down are unlikely to landing from the guide rod 7.An other side of said adjustable plate 6 offers through hole 13, is provided with drill bushing 14 in this through hole 13, and said through hole 13 keeps coaxial with the blind hole 11 of said screw rod bottom.Also be inlaid with a powerful magnet 5 in this adjustable plate 6, this magnet is near a side setting of the through hole on the adjustable plate 6.

The boring locator of the utility model is like this work: steady pin 3 is put into the blind hole 11 of bolt 1, with the upwards pulling of adjustable plate assembly, draw back height and can regulate according to the thickness of object to be processed.The height of bolt 1 can carry out height according to the object polycrystalline substance to be regulated.Then steady pin 3 upper ends are inserted and form the location in the blind hole of being bored the thing bottom naturally; Pulling adjustable plate assembly; Magnet and object to be processed nature adhesive on it is fixed, again drill bit is put into that drill bushing 14 is processed or center appearance dashed and put into drill bushing 14 and position line.
