Hub semi-water immersion detection device

Abstract

The invention discloses a hub semi-water immersion detection device which comprises a rack, a water immersion pool, a clamping rotating mechanism, a receiving and conveying lifting mechanism, a horizontal receiving and conveying mechanism and a scanning mechanism, the water immersion pool, the clamping rotating mechanism and the receiving and conveying lifting mechanism are all installed on the rack, the clamping rotating mechanism is located below the water immersion pool, and the receiving and conveying lifting mechanism is located above the water immersion pool; the upper part of the clamping rotating mechanism upwards extends into the water leaching tank; the power output end of the receiving and conveying lifting mechanism is arranged downwards, the horizontal receiving and conveying mechanism is mounted at the power output end of the receiving and conveying lifting mechanism, and the horizontal receiving and conveying mechanism is located in the water leaching pool and can be driven by the receiving and conveying lifting mechanism to move up and down in the depth direction of the water leaching pool; the scanning mechanism is arranged on the side wall of the water immersion pool, a probe is arranged on the scanning mechanism, and the probe is correspondingly matched with the upper end of the clamping rotating mechanism. The hub semi-water immersion detection device can perform full-automatic non-contact flaw detection on the hub, so that the detection cost and the labor cost are reduced, and the detection precision and the detection efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of wheel hub welding seam detection equipment, in particular to a wheel hub semi-water immersion detection device. Background technique [0002] The steel rim, also known as the wheel hub, is a metal part that supports the tire in the inner contour of the car tire. It is an important part of the vehicle, and its quality is directly related to human life safety. Wheel hubs are usually made of aluminum alloy or steel. Steel hubs have high strength and are often used in large trucks, so they have high requirements in all aspects. The steel wheel hub is welded by a laser welding machine. The pulsed laser generated by the laser is applied to the surface of the workpiece after beam expansion, reflection and focusing. The surface heat diffuses to the inside through heat conduction, and the width, energy and peak value of the laser pulse are accurately controlled by digitalization. Parameters such as power and repe...

Problems solved by technology

[0003] At present, for the scanning of such wheel hub parts, most of the wheel hub water immersion horizontal rolling scanning is used. Although this method can solve the coupling problem in the scanning process, in the actual detection process, the phased array probe often It will contact with the outer ring of the wheel hub and cause friction, which will cause serious wear and tear of the phased array probe during the inspection process. The operator needs to observe the friction degree of the ultrasonic probe from time to time and replace it with a new ultrasonic probe. Such detection will increase the detection cost and labor cost. , the detection accuracy and detection efficiency of the equipment are low
