Abstract:
1. A universal acoustic emission test sensor fixing device, comprising: a radial positioning mechanism, supporting mechanisms, bases, acoustic emission test sensor mounting mechanisms, and parallelism adjusting members, wherein the supporting mechanism, the bases, the acoustic emission test sensor mounting mechanisms, and the parallelism adjusting members are all in two sets; the supporting mechanism includes a main supporting arm and an auxiliary supporting arm, with one end of the auxiliary supporting arm fixedly connected to or hinged with the main supporting arm and the other end being provided with a ball head, and a parallelism adjusting member mounting mechanism is provided at the joint of the main supporting arm and the auxiliary supporting arm, and the bases are provided with a spherical hole therein matching the ball head of the auxiliary supporting arm; and the main supporting arms of the two sets of supporting mechanisms are respectively connected to the two free ends of the radial positioning mechanism in the way that the auxiliary supporting arms of the two sets of supporting mechanisms are respectively located at the inner sides of the main supporting arms and are arranged axis symmetrically with respect to the central line of the radial positioning mechanism, and the ball heads of the two auxiliary supporting arms are respectively located within the spherical holes of the two bases to form a universal revolute pairs, the two sets of acoustic emission test sensor mounting mechanisms are respectively mounted at the two bases, and the two sets of parallelism adjusting members are respectively mounted on the two main supporting arms via mounting mechanisms provided on the main supporting arms.
