Description

The subject of the invention is a device for deciphering profilograms captured on optical profilometers and the like. During mass processing of profilograms, this decoding is time consuming.

The device described below provides a reduction in the time spent on decoding profilograms.

FIG. 1 shows the proposed device; pas figs. 2 - its basic scheme.

The device (Fig. 1) consists of a housing 1, a guide, 2 to it with a millimeter scale, which is interleaved by means of tribka 3. A guide 2 is rigidly connected to a moving frame 4, on which, through a .5 pattus, a reticle 6 (steel tape) .

On the case there is a reinforced disk with a turntable 7, along which with the help of the head 8 can move the pointer with a cross on it. The disk with a swivel ruler is connected to the guides by means of a thin steel tape (not shown in Fig. 1).

The profilogram shown in fig. 1 with a dashed line, strengthened with the help of a narrow device over a transparent device, so that the line of depressions plotted on the profilogram of the curve coincides with a fixed sighting drink 9 (steel tape), tightened with a screw 10. After that, use the tread 3 to move the 2 until the movable reticle 6 is aligned with the line of the scallops of the curve. At the same time, a thin steel tape // (Fig. 2) connecting the disk 12 and the guide will deflect the swivel ruler 7 by the angle a, the value of which will correspond to the distance between the sighting threads 6 and 9. Or R ,.

When moving point A, which lies on the line of scallops, to point A, the distance traveled, equal to „„ „„., Is related to the angle of rotation a of disk 12 by the equation

.

The pointer 13 is set to the division of the turntable corresponding to the vertical scale of the profilogram, and according to the position of the pointer cross relative to the fixed spiral scale 14, the purity class is determined.

PRIORITY AREA

A device for interpreting profilograms taken on optical profilograms, etc., characterized in that, in order to reduce the time spent on the determination of the purity class

It is the maximum value of the irregularities recorded on the profilogram, it is made in the form of two reticle, one fixed, aligned with the line of depressions of the profilogram, and the other movable, installed along the line of its scallops and connected by means of a flexible link with a rotating bar, equipped with a movable pointer depending on the scale of the profilogram, and on the position of the pointer cross relative to the fixed spiral scale, the surface cleanliness class is determined.
