Abstract

The invention relates to the technical field of bolt non-destructive detecting, and specifically discloses a bolt ultrasonic detecting device.Thebolt ultrasonic detecting device comprises a bolt, anda guiding mechanism is arranged on the outer side of the top end of the bolt, the guiding mechanism comprises an inner rail frame and an outer rail frame, the inner rail frame and the outer rail frameare both of ring structures and are concentrically and parallelly distributed, a plurality of connecting rods are fixedly mounted between the inner rail frame and the outer rail frame, a first rail is mounted on the top of the inner rail frame, a second rail is fixedly mounted on the top end of the outer rail frame, a fixing mechanism is arranged at the bottom of the guiding mechanism,a sliding mechanism is arranged on the top of the guiding mechanism,a clamping mechanism is fixedly mounted on one side of the sliding mechanism, an ultrasonic probe is clamped on the clamping mechanism, and theultrasonic probe is located above the bolt. According to thebolt ultrasonic detecting device,the function of automatic detection is realized, data repeatability is good,detection precision is high, the position of the ultrasonic probe can be adjusted, thus the position of the ultrasonic probe is precisely controlled, and the detection precision is improved.

Description

technical field [0001] The invention relates to the technical field of non-destructive testing of bolts, in particular to an ultrasonic testing method and device for bolts. Background technique [0002] Bolt connection is one of the most common structural connection methods, widely used in energy and electricity, petrochemical, railway, shipbuilding, machinery manufacturing and other industries. Due to the complex force of bolts, dangerous defects such as cracks will occur during long-term use. In order to ensure the safety of use, ultrasonic testing of bolts is required on a regular basis. At present, the ultrasonic detection of bolts mainly uses single-chip longitudinal wave straight probes, small-angle longitudinal wave oblique probes, or phased array probes, and uses corresponding conventional ultrasonic instruments or phased array detectors. Ultrasonic detection is carried out on the threaded part and the screw part of the bolt by moving; at present, the bolt is mainly...
