Abstract

This invention relates to a measurement technique. The purpose of the invention is to improve the measurement accuracy. The device comprises a base 1 with two columns 2 and mounted on columns with the possibility of moving the carriage 4 with two support rollers 5 and 6 of different diameters. When the product 9 is moved, the carriage 4 is pressed against the product, resting on the rollers 5 and 6 and ensuring that the distance between the measuring device 7 and the surface of the product 9 is constant. 2 Il.

Description

FIG. one

The invention relates to a measuring technique and can be used to control defects, irregularities, surface roughness are moving, for example, on a product conveyor.

. The purpose of the invention is to improve the accuracy of control.

Fig, 1 shows the proposed device, a general view; FIG. 2 is a section A-A on ijMr, 1.

The device for: monitoring defects of the surface of moving parts consists of a base 1, two parallel columns 2 with stops 3 at free ends mounted on the columns with the possibility of movement of the carriage 4 along them with two support rollers 3 and 6 and with a measuring device fixed on it 7, for example a flaw detector. The carriage rests on the stops 3 and is pressed against them by two springs 8 placed on columns 2, the diameter of the front roller 5 is larger than the diameter of the rear roller 6c

The device works as follows

Before measurement, the carriage 4 is mounted on columns 2 so that the cylindrical surfaces of the rollers 5 and 6 are located slightly below the surface of the test article 9,

 When moving the product 9, for example, on a conveyor belt, the front roller 5 of the carriage 4 rolls over the surface of the product 9 and the carriage moves along the columns 2 upward, compressing the springs 8, with possible misalignment

column carriages are minimal — within the available gap between the holes in the carriage and the columns. This prevents the measuring device from touching the surface of the test item. Upon further movement of the product 9, the rear roller 6 rolls over it and the carriage 4, through the rollers 5 and 6, is fully pressed against the surface of the moving product 9, and the measuring device 7 registers the presence and size of defects on the surface.

Making the front roller of a larger diameter provides the best carriage rolling on the product being measured, and the elastic preload of the carriage to the surface of the product and the existing gap in the carriage-to-column connections allow the carriage to copy the measured surface, resulting in a constant distance between the measuring the instrument and the surface to be measured and the measurement accuracy is improved.
