Ultrasonic fault detector with spiral tracks

Abstract

The invention discloses an ultrasonic fault detector with spiral tracks. The ultrasonic fault detector comprises a box body. A supporting leg is mounted at the bottom of the box body, a threaded holeis formed in the bottom of the box body, a screw is mounted in the threaded hole, a mounting plate is arranged at the upper end of the screw, the lower end of the screw extends out of the bottom of the box body, an ultrasonic probe is mounted on the mounting plate, and the ultrasonic probe is vertically upward in the ultrasonic wave emission direction. The detector can detect not only faults of asolid casting structure, but also faults of a structure of a steel tube. A workpiece for fault detection is placed on a partition plate during use, the ultrasonic probe below the partition plate detects faults in the vertical direction, an electric slide block on the spiral tracks on the side wall of the box body can ascend on the spiral track to detect faults of the workpiece in the transverse direction, and the separation distance between the spiral tracks can be set, so that the ultrasonic probe can detect faults of the whole workpiece, and the ultrasonic fault detector is very high in workefficiency and is very convenient to use.

Description

technical field [0001] The invention relates to an ultrasonic flaw detector, in particular to an ultrasonic flaw detector with a spiral track. Background technique [0002] Ultrasonic flaw detectors are mainly used to detect defects such as pores, cracks, looseness, inclusions and unwelded defects in some steels, stainless steel, copper, aluminum, hard alloys, castings, compatible materials and welds, etc. by using the principle of ultrasound; Existing ultrasonic flaw detectors are usually hand-held by staff for detection. For some long-length steel pipes and other products, flaw detection is required section by section, and each surface must be inspected. The work efficiency is low and the staff wastes more time. Contents of the invention [0003] The object of the present invention is to provide an ultrasonic flaw detector with a helical track to address the deficiencies in the prior art. [0004] Technical solution: The technical solution adopted by the present inventi...
