Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of an on-machine tool setting gauge for an automatically controlled turning machine tool having a turret tool rest, particularly for an NC lathe.

Various types of on-machine tool setting gauges have been manufactured, such as those that use a gauge plate or a microscope. There were problems, such as the setting gauge itself having to be made specifically for the machine size.

The present invention uses commercially available calipers to position the cutting edges of internal and external tools in the length direction using the caliper's depth bar and the main and vernier scales. On the other hand, place the main scale of the caliper in an upright position on a stand that is placed on the reference surface on the fixed side, with the main scale facing downward. To provide a tool setting gauge which positions the center height of the cutting edge by applying the tool cutting edge to the end face of the depth bar by adjusting the height.

Therefore, according to the present invention, not only can it be used for tool setting as described above, but it can also be used as a normal caliper to measure workpieces after machining. It has the advantage of being able to provide an inexpensive tool setting gauge by reusing commercially available calipers.

Embodiments of the tool setting gauge of the present invention will be described in detail below.

As shown in FIG. 1, the caliper 1 is designed to measure an outer diameter, an inner diameter, and a depth using a scale 2 on a single scale and a scale 4 on a vernier scale 3.

In addition, a scale 8 serving as an index indicating the distance between the head end face 5 of the single scale and the end face 7 of the depth bar 6 is engraved on the single scale.

Further, a scale 9 for reading the scale 8 is engraved on the vernier 3.

As shown in FIGS. 1 and 2, the stand 10 is placed on the sliding surface 11 of the bed when adjusting the center height of the cutting edge.

Of course, the reference surface on which the stand 10 is placed for center height alignment is not limited to the sliding surface 11 of the bed, and the top surface of the saddle, the top surface of the cross slide, etc. can also be used.

The stand 10 is formed with a groove 13 that vertically penetrates the bottom surface 12 that is in close contact with the sliding surface 11 .

The width of the groove 13 is set to be slightly larger than the thickness of the main shaft 14.

The stand 10 also has a groove 1 perpendicular to the groove 13.
Screw holes 15A, 15B communicating with 3 are formed, into which set screws 16A, 16B are screwed.

FIG. 4 shows a method of adjusting the length of the cutting edge of the outer diameter tool To.

The dimension between the length 14 of the main scale and the length 17 of the vernier scale is
After setting the predetermined distance L1 and fixing the vernier 3 by clamping the setscrew 18, hook the measurement surface of the vernier length 17 onto the lower surface 19A of the base holder 19 for an outside diameter tool. By lightly pressing the cutting edge of the tool To against the measuring surface of the main scale shaft 14 and tightening the screws 20A and 20B, adjustment of the length of the outer diameter tool To is completed.

FIG. 3 shows a method of adjusting the length of the cutting edge of the internal tool TI.

After setting the dimension between the end apex 1 of the depth spar 6 and the depth reference plane 21 to a predetermined distance L2 and clamping the set screw 18 to fix the vernier 3, the inner diameter tool base holder 22 is The end surface 7 of the depth spar 6 is placed on the front end surface 22A, and the cutting edge of the inner tool TI is lightly pressed against the depth reference surface 21 to determine the length.

Next, a method of positioning the center height of the cutting edge by applying the cutting edge of the tool to the end face of the depth spar will be explained.

In FIG. 1, the distance from the bed sliding surface 11 of the lathe to the tool cutting edge of the inner diameter tool Ti (or outer diameter tool To), that is, the center height H, is known.

The dimension of this center height H is set as the distance between the head end surface 5 of the main scale of the caliper 1 and the end surface 7 of the depth spar 6.

That is, the center height H is calculated by assuming that the distance between the head end surface 5 of the main scale and the reference surface 21 of the depth spar 6 (that is, the total length of the caliper 1) is l, and the distance between the reference surface 21 of the depth spar 21 and the end surface 7 is h. , the center height H=#+h, and the distance h=H-A.

Total length l of caliper 1]1. Since it can be measured in advance, the distance determined by the above formula can be set using the scale 2 of the main scale and the scale 4 of the vernier scale 3.

After adjusting the distance between the head end surface 5 of the main scale of the caliper 1 and the end surface 7 of the depth spar 6 to the center height H, the setscrew 18 is clamped.

After completing the above settings, a scale 8 serving as an index indicating the center height H is engraved on the main scale to facilitate subsequent settings, and a scale 9 for reading the scale 8 is engraved on the vernier scale 3.

By making such markings, quick and reliable setting is possible.

Next, the stand 10 is placed on the sliding surface 11 of the bed.

Insert the main scale head 14 into the groove 13 of the stand 10, bring the head end face 5 of the main scale into close contact with the sliding surface 11, and then tighten the setscrew 16A.

16B to fix the caliper 1 vertically to the stand 10.

Next, turn the inner diameter tool TI that has been indexed to the machining position, and after aligning the center height by applying the tool tip to the end face 7 of the depth spar 6, tighten the poles 23A and 23B in Fig. All adjustments are complete.

The center height differs depending on the type of lathe or the manufacturer, but in the example in Figure 1, the main scale is 8 and the vernier is 9.
There is an advantage in that it can be used in common with all installed machinery by matching the two with a predetermined center height.

In that case, 1. For example, the type of center height of the installed machine is 2.
If there are three types, 40 m/m, 270 m/m, and 330 m/m, the scale will be 0.・If you mark the relevant dimensions with a circle like ◎ or [Phase], the work of setting the center height will be expedited.

In addition, if the main scale and the vernier scale 3 do not have scales 8 and 9, as shown in FIG.
There is also a method of stamping marks 25, 26, and 27 corresponding to the center height position of the machine and the number of the machine in question on one length.

Also, since the length of the outer diameter tool To is determined by the standard,
It will be easier to understand if you engrave a mark at the approximate size on scale 2 of the main shaku.

Also. Since the width of the depth reference plane 21 is narrow and there is a point on which the cutting edge of the inner diameter tool TI should rest, there is also a method of slightly extending the holding plate 28 of the depth spar 6.

Therefore, the tool setting gauge of the present invention not only allows tool setting using commercially available calipers, but also can be used as a regular caliper to measure workpieces, etc., and can be used on many types of lathes with different center heights. A general purpose that can be shared is one that has.

As described above, the present invention is not limited to the configurations shown in the embodiments, and modifications are expected within the scope of the technical idea of the present invention as described in the claims.
