Abstract

The invention relates to non-destructive testing, namely ultrasonic testing of the surface of cylindrical parts. The aim of the invention is to simplify the design and increase productivity. This is achieved by the fact that the rotation drive of the product around its axis is made in the form of rolls parallel and forming a prism, the axial movement of the product is made in the form of a chain located between the rolls, equipped with pins fixed to it, interacting with the end located on the rolls of the controlled product . 6 ill.

Description

The invention relates to non-destructive testing, namely, ultrasonic testing of the surface of cylindrical-shaped parts, for example, blanks of cylinder links of exhaust (rifting cylinders) lines of exhaust devices of spinning, spinning and twisting, roving machines.

The aim of the invention is to increase the reliability of axial movement of products.

In FIG. 1 shows a device, a longitudinal section; in FIG. 2 is a section AA in FIG. 1; in FIG. 3 is a section BB in FIG. 1; in FIG. 4-section bb in figure 1; in FIG. 5 is a view D in FIG. 3; in FIG. 6 is a section BB in FIG. 1 at the time of sorting.

The device for ultrasonic testing of cylindrical products contains two pairs of coaxially mounted rolls 1, 2 and 3, 4 (Fig. 1), connected to each other and to drive 5 by elastic couplings 6 and 7. A chain of 8 s is placed between the rolls 1, 2

pins 9 and 10 installed on it. Chain 8 receives movement from sprocket 11 of drive 5 through electromagnetic clutch 12 and chain transmission 13.

In front of the rolls 1 and 2 (Fig. 2) there is a loading mechanism for the parts to be controlled 14, consisting of inclined rails 15, a pivot arm 16 located between them, pivotally connected to the pneumatic cylinder 17. On both sides of the rolls 3 and 4 (Fig. 3 ) a sorting mechanism is located, consisting of two pairs of inclined rails 18 and 19, two pairs of pivoting levers 20 and 21 paired under the rollers 3 and 4, pivotally connected to the pneumatic cylinders 22 and 23.

The ultrasonic transducer 24 (Fig. 1) is located on top, the gap between the transducer and the surface of the part is filled with immersion fluid supplied by the electric pump 25.

The device operates as follows.

The products to be controlled 14 from the inclined rails 15 when the lever 16 is turned away from the pneumatic cylinder 17 fall onto the rolls 1, 2 continuously rotating from the drive 5 and also begin to rotate.

The electromagnetic clutch 12 is turned on and the movement from the sprocket 11 through the chain 13 is transmitted to the chain 8. The pins 9 attached to the chain 8 translate the product along the rolls 1, 2.

By moving the rotating article under the ultrasonic transducer 24, its surface is scanned. The gap between the surface of the product and the transducer is filled with immersion fluid supplied by the electric pump 25. After ultrasonic testing of the product for surface defects, the product falls onto rolls 3 and 4, where sorting is performed.

Depending on the results of the control, one of the pneumatic cylinders 22, 23 is triggered and using the rotary levers 20, 21

the product is removed from the rolls 3, 4 and the rolls are lifted onto the rails 18 or 19.

Reliability of axial movement from divisions is enhanced by performing an axial movement mechanism in the form of a chain mounted with the ability to move along the axis of the rolls with pins fixed to it, which prevents slipping of products on the rolls when moving them.
