The locating device for drilling of the precise workpiece is simple in structure, flexible and convenient to use, and high in locating precision.

Description

The using method of the boring positioner of precision workpiece

Technical field

The present invention relates to technical field of tooling clamps, particularly relate to a kind of using method of the positioner boring to accurate class Cylindrical workpiece.

Background technology

Precision workpiece many uses machining center of the high-accuracy requirement of current processing, need first workpiece to be positioned before processing workpiece, especially coupled columns bodily form workpiece carries out Drilling operation, if accurately can not locate it, workpiece is easy to rotate, and causes the precision of boring undesirable.

Summary of the invention

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

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

The using method of the boring positioner of precision workpiece, comprises the steps:

The first step, inserts workpiece from locating hole, makes workpiece need to attack Kong Chu and stretch in boring;

Second step, uses location plate, is matched by the locating slot on the plate of location, prevent workpiece from rotating with the draw-in groove on workpiece;

3rd step, puts into the V-shaped groove on base by positioning body, be then pressed on the cylinder position of positioning body by the deep-slotted chip breaker of briquetting bottom surface, is fixed on the end face of base by briquetting with the hold-down screw on briquetting end face.

The invention has the advantages that: positioning body one end milling flat and hole, end arranges dog screw and drives locating hole, workpiece is inserted locating hole uses location plate to match with the dog screw that draw-in groove and the positioning body end of workpiece end are arranged simultaneously, the rotation of restriction workpiece, and then positioning body put into V-shaped groove that base is arranged and fix with briquetting; Structure is simple, and flexible and convenient to use, positioning precision is high.

Detailed description of the invention

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

As shown in Figures 1 to 8, the present invention includes base 3, the end face 31 of base 3 has with V-shaped groove 32, arrange positioning body 1, positioning body 1 is fixed briquetting 4 in described V-shaped groove 32, the two side of base 3, with square groove 33, can be used for firm banking 3; One end of positioning body 1 is milled with plane 12, and with boring 13 in plane 12, boring 13 is blind hole, for carrying out Drilling operation to workpiece 5; The end face of positioning body 1 is fixed two dog screws 14 and has locating hole 15, and dog screw 14 is symmetrical arranged about locating hole 15; Locating hole 15 communicates with boring 13, and workpiece 5 inserts and extends in boring 13 in locating hole 5, the blind hole 52 on processing work 5; Dog screw 14 matches with the locating slot 21 on the plate 2 of location, location plate 2 one side straps has boss 22, and after workpiece 5 inserts locating hole 15, boss 22 coordinates with the draw-in groove 51 on workpiece 5, prevent workpiece 5 from relatively rotating, affect the machining accuracy that workpiece 5 is blind holes 52; Briquetting 4 bottom surface, with deep-slotted chip breaker 43, briquetting 4 end face 41 is arranged the end face 31 that hold-down screw 42 is fixed to base 3, cylinder position 11 tight fit of deep-slotted chip breaker 42 and positioning body 1;

Using method of the present invention is as follows:

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

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

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

More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention, see claim, within protection scope of the present invention, can do any type of amendment.
