DEVICE TO A FLAW DETECTOR FOR AUTOMATIC MOVING OFF SENSORS FROM THE SURFACE OF A TESTING ARTICLE

摘要

A device to a flaw detector for automatic moving-off pickups from the surface of a testing article, comprising a housing, mounted in it a lifting-arm system, comprising main levers and rollers spring-loaded relative to said housing and a carriage, in the body of which a slide with pickups is arranged, characterized in that the device is provided with a mechanism of the carriage suspension, comprising mounted coaxially with said main levers orienting and connecting levers pivoted connected by a common axis via shoulders between them, wherein one of the connecting levers is spring-loaded respective the housing; bearing pins and limiting thrusts are mounted on the carriage body, which is hollow, and parallel to a testing article - slides with wheels and bevels on the surface, facing the testing article, whereby the carriage is placed in housing of the device and held there by bearing pins, enabling said carriage to vertical displacement and turn; said lifting-arm system is provided with hinged additional two-arm levers mounted on the device housing, wherein said main levers of the lifting-arm system are designed two-shouldered, one of shoulders of which is tapered and provided with said roller, and the other shoulder is hinged connected with one of the shoulders of each of said additional two-arm levers, mounted so that enable interaction other shoulders with said bearing pins of the carriage body, whereby said slide is arranged in the carriage body enabling reciprocating movement and is spring-loaded, and said orienting levers of the suspension mechanism are mounted enabling interacting with said limiting thrusts of the carriage body.
