Abstract

FIELD: monitoring and measuring equipment.

SUBSTANCE: invention relates to control and measurement equipment and can be used for measurement of angles. Angle measuring device comprises base connected by axis with ruler made with longitudinal groove and goniometric scale, base by means of other axis is connected to the first end of the plank, the second end of the plank is connected by the pin with the rod, the first end of the pin passes through the hole of the first body and is connected to the rod, the second end of the pin is screwed into the nut and passes through the hole of the second housing, the first and the second housings are installed on the ruler and are connected to it by means of glue. Method of measuring angles consists in that, in an angle formed by the base and the ruler, inserting the tested part, pressing to the base, rotating the nut and reducing the angle, nail with rod and pin are moved along the lengthwise groove of the ruler until the tested part is in contact with the ruler and the angle is measured in degrees relative to the pin on the angular scale.

EFFECT: technical result is possibility of measuring sharp, right and obtuse angles, both on small-sized, and on large-sized parts.

Description

The invention relates to instrumentation and can be used to measure angles.

A device for measuring angles by contact method is known, comprising two rulers located at an angle and connected to each other by one end with a bolt with the possibility of rotation relative to each other with the formation of an acute angle between each other. The second free ends of the rulers are interconnected by a threaded rod equipped with a handle. The hairpin passes in the cavity of the earrings associated with the rulers. One of the earrings has a thread on its inner surface. On the chamfers of the rulers a scale is applied. The rulers are connected with the possibility of changing the angular position relative to each other and fixing it with a stopper, which is a screw that clamps the hairpin in a fixed position (see the description of the invention to RF patent No. 2145070, IPC G01B 3/02, publication January 27, 2000).

The disadvantage of this known device is that it can measure sharp angles only on small parts, on large parts this known device cannot be used to measure angles due to the location in the corner between the rulers of the studs connecting the second free ends of the rulers.

The objective of the claimed invention is the expansion of functionality.

The problem is solved in the method of measuring angles, using the inventive device, in the angle formed by the base and the ruler, put the part to be checked, press it to the base, rotate the nut and reduce the angle, rotate the nut to move the pin with the rod and pin along the longitudinal groove of the ruler until the part being checked with a ruler and opposite the pin, the angle in degrees is determined on a goniometer scale.

A device for measuring angles, containing a ruler and a threaded rod, characterized in that the base connected by an axis to a ruler made with a longitudinal groove and a goniometric scale, the base is connected to the first end of the strip by the other axis, the second end of the strip is connected by a pin to the rod, the first the end of the stud goes through the hole of the first body and is connected to the rod, the second end of the stud is screwed into the nut and goes through the hole of the second body, the first and second housings are mounted on the ruler and connected to it by glue .

This allows you to expand the functionality for measuring angles.

The invention is illustrated by drawings, where

in FIG. 1 shows a device for measuring angles when measuring sharp and obtuse angles;

in FIG. 2 - a device for measuring angles when measuring right angles.

A device for measuring angles contains:

1 - base with two holes, the distance between which is constant;

2 - ruler;

3 - strip with two holes, the distance between which is constant;

4 - axis;

5 - axis;

6 - pin;

7 - a longitudinal groove in line 2;

8 - goniometer scale in degrees on the chamfer of line 2;

9 - stock;

10 - the first building;

11 - a nut;

12 - the second building;

13 - threaded rod.

A device that implements a method for measuring angles, operates as follows.

In the angle to be measured and formed by the base 1 and the ruler 2, put the test item, press it to the base 1, rotate the nut 11 and reduce the angle. By rotating the nut 11, the pin 13 is moved with the rod 9 and the pin 6 along the longitudinal groove 7 of the ruler 2 until the part to be checked comes into contact with the ruler 2. Opposite the pin 6, the angle size in degrees is determined on the goniometer 8.

The claimed invention is intended for measuring sharp, straight and obtuse angles, both on small-sized and large-sized parts.
