Abstract

PURPOSE:To promptly and accurately obtain the perpendicularity of an electrode or the like for the subject by rotating the first axis, orthogonal with a main axis, and the second axis, orthogonal with the first axis, and minimizing in every axis a distance from the subject measured by a measuring means parallelly provided with the electrode or the like. CONSTITUTION:A laser measuring device 18, provided parallelly with a mounting shaft of an electrode 13, measures a distance to a tilt surface of a workpiece, for instance, in case of the laser measuring device 18 first measuring a distance l to a point (i) of the tilt surface, the distance l is the hypotenuse of a right triangle ijk with a perpendicular (m) from the tilt surface 22 serving as the one side, but the laser measuring device 18 is rotated about an axis 5 so as to obtain the distance l minimized, when its minimum value is obtained, the distance l agrees with the perpendicular (m), and the electrode 13 and the tilt surface 22 are opposed to each other at a right angle. That is, while the axis 5 is rotated by an actuator, the distance to the tilt surface 22 is measured by the laser measuring device 18 and input to a control means 23 detecting from this measured value the minimum value and stopping the rotation. Successively, an axis 9 is rotated by an actuator, repeating the similar action and stopping the rotation, and the electrode 13 completes its positioning of perpendicularity with respect to Z axes 5, 9.

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides an attitude correction device for adjusting the attitude of, for example, a tool of a machining tool so that it is perpendicular to a machining surface having an arbitrary inclination. It is related to.

[Conventional technology]

The workpiece fixed on D is an inclined surface on workpiece 2 having an unknown inclination angle.

Next, the operation will be explained. First, the detection bottle (to) of the dial gauge (b) is brought into contact with the electrode surface that is to be adjusted parallel to the main shaft (1), and the fluctuation of the dial gauge (b) is observed by moving the main shaft (1) up and down. If there is no deviation of this dial gauge 0f), the VILi surface with which the detection bottle 2 is in contact will be parallel to the main axis (1). If there is any deviation in the dial gauge C't), it means that the plane i [when the detection pin θ Samurai is in contact with it] and the main axis (1) are not parallel, and in this case, tighten or loosen the adjustment screw (B). By adjusting the distance between the upper Kufungo plate (a) and the lower Kufungo plate (a), the electrode surface that is in contact with the detection bottle 6I of the dial gauge (b) is connected to the main @ (1).

Did you come into contact with it? l! The birch surface (8) was adjusted parallel to the main axis (1), but in the case of the prismatic type, the pole α3 overlaps, and the conductive surface of the pond is often not parallel to the main axis (1), so Select an electrode surface that is different from the surface to be adjusted, and perform the adjustment operation on this selected surface.At this time, the adjustment screw (1).In order to rub the electrode αJ parallel to the main axis (1), the electrode α
Three or more habituation operations are required for two or more surfaces of three.

The electrode (13) adjusted as described above is attached to the main shaft (
For 1), n is performed in parallel. But in this case, ten'! The pole opening is not necessarily perpendicular to the constant fftQD plane (therefore, in order to make the electrode face perpendicular to the inclined plane), know the angle of inclination and adjust the angle accordingly. If the parallel state is tilted only by the above-mentioned parallel state, sufficient accuracy cannot be obtained.

[Problem to be solved by the invention]

Since the conventional posture correction device is configured as described above,
To set the electrode side parallel to the main axis, use the adjustment screw (
Since it is necessary to tighten and loosen B) several times, it takes a long time to accurately align the workpiece. There were issues that needed to be resolved, such as the inability to achieve accurate vertical alignment.

This invention was made in order to solve the above-mentioned problems, and an object of the present invention is to provide a posture correction device that can quickly and easily perform accurate vertical alignment without the need for setting an angle with respect to an inclined surface. With the goal.

[Means to solve the problem]

[Funny example of invention]

An embodiment of the present invention will be described below with reference to the drawings. Note that in each figure, the same reference numerals as in FIG. 7 showing the conventional example indicate the same parts, so the explanation thereof will be omitted. In Figure 1, (3) is a U-shaped member attached to the surface plate (2), and (4) is this U-shaped member (
The first actuator (5) corresponding to the first rotation means attached to the first actuator (5) is supported by the U-shaped member (3) via a bearing (6), and

It is a control means for stopping the rotational operation of.

FIG. 2 is a diagram for explaining the posture correction method according to an embodiment of the present invention, and the dotted line in the figure is the mounting shaft of the electrode α3. FIG. 8 is a diagram for explaining in more detail the posture correction method according to an embodiment of the present invention, in which (5) is the rotation axis of the first actuator (4);
(9) is the rotation axis of the second actuator (8).

Next, the operation will be explained. A laser length measuring device (G) installed parallel to the mounting axis of the electrode (■) measures the distance to the inclined surface of the workpiece (■). For example, as shown in Figure 2,
The laser length measuring device (to) first measures the distance 42 to the L point of the inclined surface measuring device.
Suppose we are measuring. As is clear from the figure, distance 1
is the hypotenuse of a right triangle 4 whose side is the perpendicular line m from the slope @.

Here, if we rotate the mounting shaft of the laser length measuring device (to), that is, the mounting shaft of the electric plate μs, around its fulcrum so that the distance l#J becomes the minimum, and find the minimum value, we can find the minimum value of m2. (b
) As shown, the distance WIJ- coincides with the perpendicular line m, and the connection 1tffα3 and the slope face each other at right angles. It is clear that if this operation is performed on two axes that are orthogonal to each other, a right angle can be reliably obtained.

Next, a more detailed explanation will be given using FIG. 3. First, @1
(5) is rotated by the first actuator (4), the distance to one slope @ is measured by the laser length measuring device fil, and is input to the control means Q. The control means (to) detects the minimum value from this measurement I and stops the rotation of the actuator (4) of @1. Next, rotate @(9) of 呵 2 by the small 2 actuator (8), and 1'J
After repeating the same operation 17 as above, stop the second actuator (8). In this way, the vertical alignment with respect to the two axes is completed.

In the above embodiment, the laser measuring corner note (to) was configured so that the 7 notes α3 were attached via the L-shaped member α, parallel to the shaft lever, but this was done as shown in FIG. Furthermore, even if the electrode σ3 is mounted in close contact with the mounting surface parallel to the mounting axis, the same effect as in the above embodiment can be obtained.

In addition, in the above embodiment, a laser length measuring device (to) is used as a representative non-contact distance measuring device as a measuring means, but measuring devices such as an ultrasonic measuring device, an infrared measuring device, or a dial gauge may also be used. Needless to say, the same effect as in the above embodiment can be obtained.
The figure shows the case where the dial gauge is wrapped around the -vL pole opening,
A dial gauge (to) is attached parallel to the mounting axis of the electrode 4 by means of a set screw (to) via a fixture (c). And the detection bottle (c) of the dial gauge (a)
With the dial gauge in contact with the inclined surface @, operate the first and second axes in the same manner as in the above embodiment, and when the deflection of the dial gauge head reaches the maximum, the first and second axes If we stop the movement of the axis, we can obtain verticality with respect to the two axes.

Furthermore, although the above embodiment describes the vertical alignment of the electrode in an electric discharge machining device, this is not limited to electric discharge machining devices only, and can also be applied to an apparatus for adjusting the position of a pond that requires vertical alignment. This is obvious, and as an example, a system for accurately measuring the 6th (2) 9th impact sound is shown, in which a ball c11 collides with a flat plate, and the impact sound generated at this time is measured by a microphone. It is used to collect and measure sound. In this case, the microphone (a) must be perpendicularly opposed to the flat plate (b), otherwise an error will occur in the measurement, so as in the above embodiment, a posture correction device (to) consisting of two axes and an actuator for rotating them is used. , the microphone attached to the posture corrector @□□□ is placed on a flat plate (
(to) are vertically opposed to each other.

Furthermore, if the vertical alignment shown in the above embodiment is carried out and then the desired angular deviation is carried out, there is also the effect that accurate angular alignment can be achieved.

Furthermore, the control means change shown in the above embodiment is equipped with a display that displays the measured value, and the first and second ! ! 2 actuators (4), (s)
[Effects of the Invention] As described above, according to the present invention, the first shaft mechanism provided orthogonally to the main shaft mechanism; A second shaft mechanism, which is orthogonal to the shaft mechanism and has a positioning object, is rotated by the first and second rotating means, and the second shaft mechanism is provided parallel to the mounting axis of the positioning object. The distance to the object is measured using a measuring means, and when the measured value reaches the minimum distance, the above I! Since the rotation of the first and second shaft mechanisms is stopped, the vertical positioning of the object on an inclined surface having an unknown angle can be quickly and easily performed without measuring the angle. There are effects such as being able to do it.
