  • Automation of weld inspection

    .The article discusses methods and means for monitoring weld defects. The types of defects and their impact on the performance of the product are listed. It has been shown that the ultrasonic method is best suited for testing the seams of pipe fittings. On the basis of the analysis of the design and the principle of operation of the ultrasonic flaw detector, a technique for automated control of defects has been developed. The results of control according to the written method are provided. Further ways of automation of the UCD-50 IPS flaw detector and its analogs are described.

  • The problem of choosing the layout of robotic technology complex

    When creating robotic technology complex Assembly must choose the right type of robotic arm and the drive to develop and the design of grippers, link manipulator with the accepted technological equipment, to create a system of locks and so on, To determine the required characteristics of manipulative and gripping devices was conducted statistical survey assemblies for structural and technological characteristics of the Assembly and the selected optimum performance of the robot. In paper To synchronize operations to determine the standard time used in the construction of cyclograms, from which one can see the duration and sequence of Assembly transitions. An algorithm is developed to coordinate the work of individual mechanisms to prevent their collision, ensuring the specified relative position of each mechanism at a specific moment in time that defines the time rate of each technology transition

  • Selection of the optimal structure and method of performing assembly operations

    The practice of using pneumovortical assembly methods has confirmed their high efficiency and reliability. But at using assembly equipment units, first of all orienting-assembly modules (OAM) there were some cases when the part fed to the plate performing rotating-swinging oscillations, didn't reach the seatings meant for it, and sometimes even left the plate. It was accounted for an unfavourable combination of a number of the module's constructive parameters, and also the parameters characterizing its working conditions. So it would be rather timely to analyze orienting-assembly modules with the purpose of revealing such meanings of their parameters, at which parts’ orientation and assembly is carried out with 100 percent reliability, and, if possible, at a minimal time. In other words, the parametric optimization of pneumovortical modules is necessary, and, first of all, of the orienting-assembly ones (OAM).
