Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a welding seam quality detection device. Background Art

[0002] Welding is a processing method that combines welded parts by heating or pressurizing, or both. Welding is widely used in industrial fields such as pipelines and steel structures. After welding, the welded parts need to be inspected for welding quality. Most inspection methods use ultrasonic detectors to inspect welds, which can accurately detect the exact location and size of internal defects in welds.

[0003] Among them, pipeline welding is usually completed at the installation site. After the pipeline is welded, workers are required to hold an ultrasonic probe to inspect the welding quality around the weld. Since the weld at the connection end of pipeline parts is a circular arc surface, the ultrasonic probe is easy to deviate from the weld when the worker holds the ultrasonic probe around the weld for inspection. The distance between the ultrasonic probe and the weld is easy to change. The above problems will lead to inaccurate detection data. Utility Model Content

[0004] The utility model aims to provide a weld quality detection device, which can improve the accuracy of detection data.

[0006] The working principle and effect of the above scheme: This device is used for pipelines that have been welded and installed on site. When the device is used to detect the weld of the pipeline, the device is pushed to move the device to the weld, the pipeline to be detected is placed between the two pads, and the double-axis motor is started. The double-axis motor drives the two U-shaped plates to approach each other through the first screw until the pipeline is clamped between the pads of the upper and lower U-shaped plates. At this time, the bottom plate leaves the ground, and the slide plate slides downward along the column so that the upper arc plate moves downward and contacts the lower arc plate. At this time, the two arc plates form a ring, and the center of the pipeline and the center of the ring are at the same position; when the detection structure is working, the detection structure slides along the arc plate, and the rotation trajectory of the detection structure on the two arc plates can form a circle. The weld and the detection component are both on the same side of the arc plate. At this time, the detection component can detect the weld of the pipeline; after the detection is completed, the slide plate is slid upward to separate the two arc plates, and the double-axis motor is started to move the two U-shaped plates away from each other, and the pipeline can be further taken out.

[0007] Through the pad and the arc plate, the clamping assembly can clamp the pipe between the upper and lower pads when working, so as to avoid the deviation of the detection structure and the weld. When the two arc plates are in contact, a circular ring can be formed. The center of the pipe and the center of the circular ring are at the same position. The detection structure can move around the outside of the pipe during detection. During the movement of the detection structure, the distance between the detection structure and the weld will not change, which can further improve the accuracy of the detection data.

[0011] The ultrasonic probe has a scanning angle. When the ultrasonic probe is located at the end of the arc plate, the ultrasonic probe can detect the weld position corresponding to the joint of the end surfaces of the two arc plates. When the detection structure is working, the drive motor is started, and the drive motor drives the drive gear to rotate. The drive gear is engaged with the rack to drive the base to slide along the through groove, and further drive the ultrasonic probe to move along the through groove.

[0013] The second motor is started, and the second motor drives the second screw rod to rotate. The rotation of the second screw rod can drive the slide plate to move up and down.

[0016] According to the weld quality inspection device, the cushion block is rotatably provided with a ball.

[0017] By setting the ball, when the pipeline is clamped between two pads, the contact area between the pad and the pipeline can be reduced; when detecting multiple welds on the pipeline, the device can be pushed along the pipeline, and the ball rolls along the pipeline, and the device can be further moved to the next weld to be detected.

[0018] According to the weld quality inspection device, a universal wheel is arranged at the bottom of the base plate.
