Wheel non-destructive testing equipment

Abstract

The invention discloses a nondestructive testing device for a hub. The device comprises a conveying track with position relatively fixed, a clamping and rotating unit, an imager and an X ray tube, wherein the imager and the X ray tube are oppositely arranged in the vertical direction, the conveying track and the clamping and rotating unit are horizontally arranged between the imager and the X ray tube, and the clamping and rotating unit is located below the conveying track; the clamping and rotating unit drives an input gear to rotate through an input rack and drives an output gear to rotate at the same time, then output racks are driven to stretch or retract to drive first installation plates to move along a first installation arm, a motor, a reduction gearbox and a turn wheel are installed on each first installation plate, and each turn wheel is driven by the corresponding motor to rotate. By the adoption of the structure, the hub can be lifted and rotated through the clamping and rotating unit after moving to a position right facing the portion between the imager and the X ray tube along with the conveying track, so that the hub can be detected more comprehensively and conveniently with less effort. The device has the advantages of being ingenious in concept, easy to produce, low in production cost and the like.

Description

technical field [0001] The invention belongs to the technical field of wheel hub detection, and in particular relates to a wheel hub non-destructive testing equipment. Background technique [0002] At present, the hub is an important component that connects the brake drum, the wheel disc and the half shaft. Wheel hubs are to cars what legs are to people. The car will generate lateral and longitudinal loads during driving, and with various forces such as driving torque and braking torque, the wheel hub will bear a considerable part of the load. As the speed of the car becomes faster and faster, the requirements for the dynamic stability and reliability of the wheel hub are also getting higher and higher. Whether there are internal defects plays a decisive role in the stability and safety of the wheel hub, but internal defects cannot be found only by "naked eyes", and can only be detected by non-destructive testing technology. [0003] The existing non-destructive testing o...

Whether there are internal defects plays a decisive role in the stability and safety of the hub, but internal defects cannot be found only by "naked eyes", and can only be detected by non-destructive testing technology

[0003] The existing non-destructive testing of wheel hubs is mainly carried out by X-ray testing equipment. The common X-ray testing equipment for wheel hubs mainly includes a platform and a rocker arm. Imagers and X-ray tubes are installed at both ends of the rocker arm, and the rocker arm is on a vertical plane. Internal rotation, the platform is a fixed platform, and the wheel hub cannot move after being moved to the platform. The detection of different parts of the wheel hub can only be realized by the rotation of the rocker arm. Not only is it inconvenient to use, but also the detection is not comprehensive enough.
