Abstract

The invention relates to a positioning device used in the drilling process of a precision workpiece. The device comprises a base, wherein a V-shaped groove is formed on the top surface of the base; a positioning body is arranged in the V-shaped groove; a pressing block is fixed on the positioning body; square grooves are formed on the two side walls of the base; a plane is milled at one end of the positioning body and provided with a drilled hole; two positioning screws are fixed on the end face of the positioning body; a positioning hole is formed in the end face of the positioning body and communicated with the drilled hole; the positioning screws are matched with positioning grooves on a positioning insert plate; a boss is formed on one side of the positioning insert plate; after the workpiece is inserted into the positioning hole, the boss is matched with a clamping groove on the workpiece; an arc groove is formed on the bottom surface of the pressing block; and fixing screws are arranged on the top surface of the pressing block. The device has a simple structure, is flexibly and conveniently used and is high in positioning accuracy.

Description

The boring positioner of precision workpiece

Technical field

The present invention relates to technical field of tooling clamps, relate in particular to a kind of positioner that accurate class cylinder Workpiece boring is used.

Background technology

The precision workpiece of the high-accuracy requirement of processing at present uses machining center more, before being processed, workpiece needs first workpiece to be positioned, especially carry out Drilling operation on coupled columns bodily form workpiece, if can not accurately locate it, workpiece is easy to rotate, and causes the precision of holing undesirable.

Summary of the invention

The present invention is directed to above-mentioned shortcoming of the prior art, provide a kind of precision workpiece boring positioner, it is simple in structure, and is flexible and convenient to use, and positioning accuracy is high.

The technical solution adopted in the present invention is as follows:

The boring positioner of precision workpiece comprises base, has with V-shaped groove on the end face of base, in described V-shaped groove, positioning body is set, fixing briquetting on positioning body, and the two side of base is with square groove; One end mill of positioning body has the plane, and on the plane, with boring, the end face of positioning body is fixed two dog screws and had locating hole, and locating hole communicates with boring; Dog screw matches with the locating slot of location on plate, and plate one side, location is with boss, and after workpiece inserted locating hole, boss coordinated with draw-in groove on workpiece; The briquetting bottom surface arranges hold-down screw with deep-slotted chip breaker on the end face of briquetting;

Further technical scheme is as follows:

Dog screw on described positioning body is symmetrical arranged about locating hole;

Locating slot on the plate of described location is symmetrical arranged about boss.

The invention has the advantages that: in an end mill plane and the boring of positioning body, dog screw is set and drives locating hole on end, workpiece is inserted locating hole uses the location plate to match with the draw-in groove of workpiece end and the dog screw of positioning body end setting simultaneously, the rotation of restriction workpiece, and then positioning body is put into the V-shaped groove that arranges on base and fixed with briquetting; Simple in structure, flexible and convenient to use, positioning accuracy is high.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.

To shown in Figure 8, the present invention includes base 3 as Fig. 1, have with V-shaped groove 32 on the end face 31 of base 3, the interior positioning body 1 that arranges of described V-shaped groove 32, fixing briquetting 4 on positioning body 1, the two side of base 3 can be used for firm banking 3 with square groove 33; One end mill of positioning body 1 has plane 12, and on plane 12, with boring 13, boring 13 is blind hole, is used for workpiece 5 is carried out Drilling operation; The end face of positioning body 1 is fixed two dog screws 14 and is had locating hole 15, and dog screw 14 is symmetrical arranged about locating hole 15; Locating hole 15 communicates with boring 13, and workpiece 5 extends in boring 13 from the interior insertion of locating hole 5, the blind hole 52 on processing work 5; Dog screw 14 matches with the locating slot 21 of location on plate 2, plate 2 one sides, location are with boss 22, and after workpiece 5 inserted locating holes 15, boss 22 coordinated with draw-in groove 51 on workpiece 5, prevent that workpiece 5 from relatively rotating, affect the machining accuracy that workpiece 5 is blind holes 52; Briquetting 4 bottom surfaces arrange the end face 31 that hold-down screw 42 is fixed to base 3 with deep-slotted chip breaker 43 on briquetting 4 end faces 41, cylinder position 11 tight fits of deep-slotted chip breaker 42 and positioning body 1;

Using method of the present invention is as follows:

The first step is inserted workpiece 5 from locating hole 15, make workpiece 5 need to attack Kong Chu and stretch in boring 13, as shown in Figure 2;

Second step uses location plate 2, and the locating slot 21 on the plate 2 of location is matched with draw-in groove 51 on workpiece 5, prevents that workpiece 5 from rotating, as shown in Figure 5;

The 3rd step, positioning body 1 is put into V-shaped groove 31 on base 3, then the deep-slotted chip breaker 43 of briquetting 4 bottom surfaces is pressed on the cylinder position 11 of positioning body 1, with the hold-down screw 42 on briquetting 4 end faces 41, briquetting 4 is fixed on the end face 31 of base 3, as shown in Figure 8.

Above description is explanation of the invention, is not that limited range of the present invention within protection scope of the present invention, can be done any type of modification referring to claim to the restriction of invention.
