Description

Utilize the sensor anchor clamps of ultrasonic guided wave detecting angle member defective

Technical field

The utility model relates to a kind of sensor anchor clamps, and especially a kind of sensor anchor clamps that utilize ultrasonic guided wave detecting angle member defective belong to the non-destructive detecting device technical field.

Background technology

The angle member defective adopts ultrasonic detection method usually; Traditional ultrasonic detection method is to go out a smooth probe moving area and smear couplant in angle member surface finish to be detected; Use the supersonic guide-wave probe laterally to move then and carry out scanning along this probe moving area; Pointwise detects, and finds out the position of weld defect.Because the method that this pointwise detects is to be attached to the angle member surface by operating personnel's hand-held sensor to carry out signals collecting and pick up, usually since the artificial origin sensor is produced rocks; Cause echoed signal unstable, influence the accuracy of testing result, prolong detection time; Inefficiency; Because check point is more, labor intensity of operating staff is big, easy fatigue simultaneously.

Summary of the invention

The purpose of the utility model provides a kind of simple in structure, easy to operate, sensor anchor clamps that the sensor accurate positioning utilizes ultrasonic guided wave detecting angle member defective reliably.

The utility model is achieved through following technical scheme:

A kind of sensor anchor clamps that utilize ultrasonic guided wave detecting angle member defective; Comprise the last fixture block that laterally arranges, following fixture block, the side fixture block that is arranged on fixture block and following fixture block one side, the auxiliary fixture block that is fixed on the fixture block opposite side and several puller bolts; Said upward fixture block, following fixture block one side are fixedly connected with side fixture block two ends respectively; Last fixture block downside is provided with locating slot, and on one side on said between fixture block and the play fixture block, a plurality of sensors are arranged side by side on angle member one side angle member; And the locating slot longitudinal register through last fixture block downside; The sensor outside is through side pad, auxiliary fixture block located lateral, and several puller bolts pass down fixture block respectively, withstands on angle member bottom on one side through lower gasket.

The purpose of the utility model can also further realize through following technical measures.

The aforesaid sensor anchor clamps that utilize ultrasonic guided wave detecting angle member defective; Wherein said side fixture block middle part is provided with the longitudinal register groove, and side fixture block one side is provided with locating piece, and a plurality of sensors are arranged side by side on the end face of angle member one end; Sensor one side is through longitudinal register groove, locating piece location; The sensor opposite side overlays in angle member one flank side surface, and several puller bolts pass fixture block, following fixture block respectively, withstand on angle member top and bottom respectively through lower gasket.

The aforesaid sensor anchor clamps that utilize ultrasonic guided wave detecting angle member defective, wherein said sensor is a piezoelectric sensor.

The utility model is simple in structure, and is easy to operate, because the degree of freedom of sensor all directions all is limited; Difficult generation is rocked, and the sensor accurate positioning is reliable, and echoed signal is stable; Guaranteed the accuracy of testing result; Detection time is short, has alleviated labor intensity of operating personnel greatly, has improved work efficiency.

Advantage of the utility model and characteristics will illustrate through the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide with reference to accompanying drawing as an example.
