(54) DEVICE FOR ULTRASOUND CONTROL OF CYLINDRICAL PRODUCTS

one

The invention relates to non-destructive testing methods, namely, to means of ultrasonic testing of the quality of materials and the geometric dimensions of pipes, rods, rods and other cylindrical articles.

A device for ultrasonic testing of cylindrical articles is known, comprising a shoe with a base, a flexible separating element, a finder, and mechanisms for adjusting and locating the finder t.1}.

The disadvantages of this device are the limitation of the scope of use of one size of cylindrical products, which can be controlled without retooling the device, which leads to low accuracy and productivity of control.

The purpose of the invention is to expand the scope, improve the accuracy and performance of the control.

This goal is achieved by the fact that the device is equipped with a mechanism for clamping the product, which can be made in the form of a frame pivotally connected to the shoe, fitted with a spring-loaded lock and pressure prisms, and the working surface of the shoe is made in the form of a chute with a radius of curvature equal to the maximum outer radius controlled from 10 .

FIG. 1 shows the device, a general view; in fig. 2 - the device, view from the side of the spring-loaded lock.

13

The device contains a shoe 1, the working surface 2 of which is made in the form of a chute with a radius of curvature equal to the maximum outer radius of the product under test.

Claims (2)

20 The shoe 1 is fixed on the base 3, to which is also attached a flexible separating element 4. In the shoe I there are two openings 5 and 6, one 3 in C5 length. supplying the contact bar, another (6) is the upper part of the immersion bath formed by the flexible element 4. At the same distance from the hole 6 in the base 3, three alignment racks 7 are fixed, on which the cup 8 is positioned with the possibility of movement on racks 7, it is determined and fixed by nuts 9 with taper end surfaces. In the glass 8, a fork 10 is installed with the possibility of translational movement, on the threaded end of which a nut 1 1 is located, interacting through a screw 12 with an annular groove on the glass 8. At the opposite end of the fork 10 a finder 13, which is the bottom of the immersion bath, and flexible separation element 4 The shoe 1 is pivotally fixed through the bar 14 of the presser frame 15, in the bar 14 there are grooves for adjusting the position of the frame 15 On the opposite side to the frame 15 there is attached a plan ka 16, in which also adjusting knobs are made Shl. The plate 16 is attached to the screw 17 fixed on the shoe 1 by the zashom 18, which is connected to the frame 15 through the spring 19, the tension adjustment of which is driven by the screw 20. The clamping prisms 21 are fixed on the SIZE 15 of the frame 15. For example, to control the wall thickness of the pipe, rotating the nut 11 sets the required distance from the finder 13 to the working surface 2 of the shoe 1 and fixes it with a screw 12, then adjusting the finder 13 by adjusting the tube by moving the stack to 8 nuts 9 and then fixing it mi Next, the working surface 2 of the shoe 1 is set to the controlled product and the position of the frame 15 is adjusted by moving it in the grooves of the slats 14 and 16. The force of the product to be pressed by the spring 19 to the working surface 2 of the shoe is adjusted by means of 20. At the transition to inspection of pipes of another type, measure It is necessary to adjust only the position of the frame 5 and the force of the spring 19. The installation allows monitoring of pipes of all diameters without replacing the shoe 1. After aligning the finder 13 at the beginning of the control, the wall thickness is controlled when the wall thickness is changed These re-alignment tubes are not required, and only the searcher 13 is moved, as this adjustment is not disturbed. Claim 1. A device for ultrasonic testing of cylindrical articles containing a shoe with a base; a flexible separator element, a finder and mechanisms for adjusting and rotating the seeker’s mixing, characterized in that, in order to expand the field of application, to improve the accuracy and productivity of the control, it is equipped the pressing mechanism of the product, and the working surface of the shoe is made in the form of a chute with pa, n, with a curvature angle equal to the maximum outer radius of the controlled product. 2. The device according to claim 1, characterized in that the mechanism for clamping the product is made in the form of a frame pivotally connected to the shoe, provided with a spring-loaded lock and clamping prisms.
