Description

It is a kind of to process the drilling tool for being mutually perpendicular to hole
Technical field
The present invention relates to mechanical processing frock field, is specifically a kind of drilling tool processed and be mutually perpendicular to hole.
Background technology
In mechanical processing, product class part is common part, the general small volume of such part (length and width, it is high no more than 50), need to complete to be mutually perpendicular to the processing in hole in Different Plane in processing, within the pitch-row requirement generally 0.2 between holes, Hole position ensures that difficulty is larger.
At present in the processing of such drilling part, generally there are two methods:One kind is to be bored after drawing hole bit line with centering of ruling Hole, another kind are to drill on numerically-controlled machine tool by zero migration coordinate of size datum.There are following for both the above method Deficiency:
The method drawn and drilled after the bit line of hole with centering of ruling is used, although method is simple, the positional precision in hole is relatively difficult to ensure Card, suitable for the processing in the relatively low hole of dimension precision between the holes.Need precisely to rule before drilling, need to carry out in boring procedure multiple test drilling with Progressively correction hole position, it is not only less efficient, and also machining accuracy is poor.
The method processed using numerically-controlled machine tool, directly can be deviateed coordinate as zero point using size datum face and be processed, precision It is higher.But the processing for two upright openings in Different Plane is, it is necessary to which clamping or machine tool chief axis stand sleeping conversion post-processing, processing twice Cost is higher.Meanwhile required for the pitch-row on the basis of the center of hole, can not be directly using hole center as machining benchmark, can only By dimension conversion to machining benchmark, by adding tight pitch-row to ensure the relative position between hole, processing method is more complicated.
The content of the invention
To overcome the problem of high processing costs existing in the prior art, efficiency are low and precision is poor, the present invention proposes one Kind processing is mutually perpendicular to the drilling tool in hole.
The present invention includes base, body, tight fixed bolt, block, the first drill bushing, the second drill bushing, wherein:Under the body End is fixed on the upper surface of base, and the two sides of the body are stuck on the two sides of the base upper surface boss, and makes this The surface of body two sides is bonded with the surface of base boss two sides.Circumferential closed drilling tool is constituted by the body and base Cavity;Block is bolted on the side surface of the body, and positioned at there is tight fixed bolt side;The lower surface of block has convex The product orientation block gone out.The upper surface of base boss in the drilling tool cavity is the first product orientation face, in the drilling tool cavity A side surface be the second product orientation face.One side surface of block length direction is the 3rd product positioning surface;
There is the second drill bushing mounting hole on a side of the body, and make center and the installation of the second drill bushing mounting hole The central coaxial in the hole to be processed of product side surface afterwards;There is the first drill bushing mounting hole in the upper surface side of the body, and Make the first drill bushing mounting hole center and installation after product upper surface hole to be processed central coaxial;
The diameter of the second drill bushing mounting hole is identical with the outside diameter of the second drill bushing;First product orientation face of the body On have chip removal through hole;The chip removal through hole and the second drill bushing mounting hole are concentric.Tight fixed bolt is provided with the upper surface of the body Mounting hole, and make the position of the mounting hole corresponding with the product space after installation;First drill bushing is installed on first drill bushing In mounting hole.
The upper surface middle part of the base has boss;There are two to be used to pacify respectively in the edge of two long sides of base Fill the through hole of attachment screw.There is chip-removal hole in the boss upper surface, the chip-removal hole and the first drill bushing on body are concentric. The boss upper surface and the depth of parallelism of the base lower surface are not more than 0.03.
The side of the body is provided with groove, make the shape of body u-shaped, and the groove is on the body Position is determined according to the shape of product, and makes the hole to be processed on product and the first drill bushing mounting hole on body concentric;Institute The wall thickness for stating groove two side is different.
Concentric through hole is provided with the body recess two side;The through hole of the side small positioned at wall thickness be and the second drill bushing Second drill bushing mounting hole of interference fit;Through hole positioned at the big side of wall thickness is chip-removal hole.Have first on the groove slot bottom Drill bushing mounting hole, and make the first drill bushing mounting hole and the hole to be processed on product concentric;The hole of the first drill bushing mounting hole It is interference fitted between the outside diameter of footpath and the first drill bushing.There is block mounting hole in the small side of the body recess wall thickness, for by institute State the side surface that block is fixed on the body.
The block is inverted "convex" shaped.
When product loads in the drilling tool cavity, and make a side surface of the product and the 3rd on the block Product orientation face paste is closed, and the basal surface of the product is bonded with the first product orientation face mating surface in drilling tool, is made the product Tool back plane is bonded with the second product orientation face mating surface in drilling tool.Product is compressed by tight fixed bolt, completes determining for product Position clamping.Drilling tool is overturn, is drilled respectively behind centering drill bushing center, you can completes the processing of two upright openings in Different Plane.
Energy clamped one time of the invention is completed to be mutually perpendicular to the processing in hole in Different Plane, solves hole position precision and is difficult to protect The problem of card, efficiency are low, high processing costs, hole position precision and uniformity are preferable, have using simple, high precision machining, processing The characteristics of cost is low.
