The specific embodiment

Fig. 1 and Fig. 2 show a kind ofly representative has the inclined-plane at outer peripheral face, and the workpiece to be processed 30 of the processing of need holing on the inclined-plane.As depicted in figs. 1 and 2, has inclined-plane 33 on the outer peripheral face of this workpiece to be processed 30.The through hole 31 that has drawn among the figure and on processing later should the inclined-plane 33 at workpiece to be processed 30, processed, in fact three through holes 31 though only drawn among the figure, need to process four such through holes 31 on workpiece to be processed 30, and the central angle between these through holes 31 is 90.In addition, on workpiece to be processed 30, also has elongated slot 32.

Fig. 3 and Fig. 4 show the drilling tool of an embodiment of the utility model.The base of this drilling tool is made of base plate 1 and swash plate 2.The angle of this swash plate 2 is 45 °.Thereby after being installed in mainboard 3 on this base, the inclination angle of this mainboard 3 is 45 °.

Fixed jacket 4 is installed on the mainboard 3.As shown in Figure 5 and Figure 6, on this fixed jacket 4, between locating

surface

4b and 4c, form step, be used for location overcoat 5 is positioned.In addition, have screwed hole 4a, can will locate overcoat 5 and be fixed on the fixed jacket 4 by the cooperation of bolt 8b and screwed hole 4a at the sidepiece of fixed jacket 4.

Location overcoat 5 is installed on the fixed jacket 4.As shown in Figure 7 and Figure 8, have locating slot 5a on the outer peripheral face of location overcoat 5, on this locating slot 5a, have positioning spiro pit 5f.Can boring cover 6 be installed by this locating slot 5a, positioning spiro pit 5f.On this location overcoat 5, also be provided with screwed hole 5d is installed.As mentioned above, can should locate overcoat 5 and be fixed on the fixed jacket 4 by the bolt 8b that cooperates with screwed hole 4a on the fixed jacket 4 and the cooperation between this installation screwed hole 5d.On this location overcoat 5, also be provided with positioning through hole 5b, be used for to wherein inserting the second alignment pin 9b, so that axle sleeve 10 is fixing with it.Has through hole 5e in this location overcoat 5.In addition, on the overcoat 5 of location, also have screwed hole 5c, be used for behind the location of carrying out 5 in axle sleeve 10 and location overcoat by the second alignment pin 9b,, they being fixed together by being screwed into the bolt 8c of this screwed hole 5c.

Axle sleeve 10 is inserted in the overcoat 5 of location.As shown in Figure 5, have four blind hole 10a on the outer peripheral face of this axle sleeve 10, the central angle between these four blind hole 10a is 90 °.In other words, the central angle between four blind hole 10a equates.In the present embodiment, employing be blind hole 10a, but be not limited to this, also can adopt through hole.

Also be provided with through hole 10b on the sidewall of axle sleeve 10, this through hole 10b is used for fixing locating piece 11.Between the interior bone 10c of

axle sleeve

10 and 10d, be formed with step 10e.After inserting this axle sleeve 10 on the overcoat 5 of location,, make the part that only is arranged on the axle sleeve 10 more than Fig. 9 and Figure 10 step 10e be inserted into location overcoat 5 by this step 10e.

Locating piece 11 is arranged in the axle sleeve 10.As Figure 11 and shown in Figure 12, has through hole 11a on it.Insert the through hole 10b of axle sleeve 10 and the locating hole 11a of locating piece 11 by the first alignment pin 9a, can limit moving axially of axle sleeve 10 by workpiece to be processed 30.

Boring cover 6 is arranged on the locating slot 5a of location overcoat 5.As Figure 13, Figure 14 and shown in Figure 15, on the outwardly directed part of this boring cover 6, has through hole 6a.This through hole 6a be used to hole the cover 6 with the location 5 in overcoat be connected.

In addition, Figure 13 middle and lower part at boring cover 6 has through hole 6b.Drill jig cover 7 can be installed in this through hole 6b.By drill jig cover 7 is set, the service life of the cover 6 that can guarantee to hole.But this drill jig cover 7 can be set also.

This part that through hole 6b is set at boring cover 6 also has projection 6c, and this projection 6c is used for engage with respective grooves on the workpiece to be processed 30, with vertically mobile of restriction workpiece to be processed 30.

Though not in detail expression among Figure 13-Figure 15, should boring overlap lean among Figure 13 of 6 last part and by under part between the one-tenth angle be 135 °.Like this, under the state of as shown in figure 16 installation, the axis normal that can make this installation drill jig cover 7 is in the bottom surface.

The second alignment pin 9b is arranged on axle sleeve 10 and locatees 5 in overcoat, is used for the two is positioned.

The using method of following this drilling tool of simple declaration.

At first, need locating piece 11 is positioned in the elongated slot 32 of workpiece to be processed 30.Then, axle sleeve 10 is enclosed within on the processing work 30, and on locating piece 11 and axle sleeve 10, inserts the first alignment pin 9a.Thus, limit the rotation of workpiece to be processed 30 by locating piece 11.

Then, axle sleeve 10 is inserted in the overcoat 5 of location.

Then, the cover 6 of will holing is installed on the overcoat 5 of location, limits moving axially of workpiece to be processed 30.And in boring cover 6, put into drill jig and overlap 7.

Then, rotary axle box 10 by the second alignment pin 9b, limits relatively rotating between axle sleeve 10 and the location overcoat 5.Then, can pass through bolt 8b, axle sleeve 10 and location overcoat 5 are fixed.

Thus, install, can be by boring cover 6 boring on workpiece to be processed 30.

And can after having bored first hole, unscrew bolt 8c, and extract the second alignment pin 9b, rotary axle box 10 to the left or to the right, make it to rotate 90 °, carry out the processing in next hole.And by that analogy.Can on workpiece to be processed 30, process 4 holes.

When pulling down, adopt opposite action for processing work 30.

In the present embodiment, owing on axle sleeve 10, only be provided with 4 blind holes, thus can only on workpiece to be processed 30, process four through holes, but be not limited to this, can process more hole by more blind hole is set.

In the above-described embodiment, limit moving axially of workpiece to be processed 30 by boring cover 6, but be not limited to this, also can adopt other means, for example, pin, bolt etc. limit moving axially of this workpiece to be processed.
