SU744318A1 - Arrangement for ultrasonic testing of cylindrical articles - Google Patents

Description

by means of fixed gear wheels 8, spindles 9, 10, at one end of each of which the normal search heads 5 are fixed, and at the other end of one of the spindle 9) gear 11 interacting with the last rack 12 and connected to the rack crank gear Shuatinago mechanism 13, and ABYaz11-1, with a capacity of 7, an immersion liquid dispenser, made in the form of a tip 14 with openings of rectangular section tapering to the outlet. The device for ultrasound testing works in the following way. The controlled article 2 is driven / driven in a positive movement. Arguing heads 4, 5, with the help of an iodzhati mechanism, are brought into contact with a controlled product 2, simultaneously simultaneous normal searching heads 5, by means of a reversible rotation mechanism, gifod ts in a return movement around their acoustic axes, through the tip M iodine reflex immersion fluid is applied to the heads. After completing the above-mentioned opapia, the movement of the search heads is switched on. In the process of control, the normal search heads perform complex movements: together with the device, they move along the generator of the product at a constant linear velocity, while at the same time making a reciprocating rotational movement around the acoustic axes with an angle of at least 180 °. Due to the reciprocating motion, the treads of the normal searching heads wear evenly over their entire surface. This eliminates factors affecting the sensitivity of the control.

Erag) №2k IvETav1et. | Claims 1. Ultrasonic testing device for cylindrical products, containing a drive for rotating the controlled product around its axis, a housing, housing innumerable inorganic search heads, a mechanism for moving the search heads, a mechanism for pressing them against the product, and a container with | IMmersioi fluid , characterized in that, in order to eliminate the uneven wear of the protectors of normal ascetic heads and to create a reliable acoustic contact, it is equipped with a reverser mechanism The normal rotation of the searchlight heads around its axis, and the capacitance-related distributor of the immersion fluid network, shaped like a tip, with rectangular openings tapering to the outlet, the number of which corresponds to the number of search heads. . 2. Hazardous TI. , from l and -: This is due to the fact that the mechanism of the reverse rotation of normal searching heads is made in the size of the housing and. their action with each other by means of fasteners on Finx gear Ko; iec, siiideli, on the o.pum end of each For which the normal search heads are strengthened, and on the other side of one of the three-piece gear --- gear that interacts with the last toothed rack and connection}; Wow with the rack red; 1Wash: III-Shatuppogo mechanism.
