Description
Technical Field
The utility model relates to a cylinder liner product failure detection device belongs to cylinder liner check out test set technical field.
Background
If the cylinder liner product has internal defects such as micro-cracks, sand holes and the like, the cylinder liner product is easy to fail due to high temperature and high pressure during use, so the detection of the internal defects of the cylinder liner product is very important. Patent CN200910065555.3 discloses a special eddy current flaw detector for cylinder liners, which can effectively detect the internal defects of the cylinder liners by using the electromagnetic induction principle. The eddy current flaw detector in the patent uses a clamp to fix the cylinder liner, when the clamp has a large clamping height on the bottom of the cylinder liner, the probe penetration depth during the detection of the probe is influenced, and the cylinder liner cannot be subjected to comprehensive flaw detection; when the clamping height of the clamp to the bottom of the cylinder liner is small, the clamping firmness is low, and the cylinder liner rotates due to the action of centrifugal force, the eccentric problem possibly occurs, so that the gap between the probe and the surface of the cylinder liner fluctuates, and the detection accuracy is influenced.
Disclosure of Invention
To the above problem, the utility model provides a cylinder liner product detection device that became invalid, concrete scheme is:
a cylinder liner product failure detection device comprises a workbench, wherein a rotating shaft arranged transversely is arranged on the workbench, a centering clamp is arranged at the end part of the rotating shaft, a transverse sliding rail is arranged on the workbench along one side opposite to the rotating shaft, a probe base is arranged on the transverse sliding rail in a sliding manner, and an eddy current flaw detection probe is fixed on the probe base; a riding wheel is arranged between the rotating shaft and the transverse sliding rail, and the riding wheel is positioned below the centering clamp along the vertical direction; the probe base is provided with a transverse guide rod, and the guide rod is in sliding fit with the guide hole.
Furthermore, the workbench is provided with two opposite vertical seats, and the rotating shaft and the transverse sliding rail are respectively fixed on the two vertical seats.
Further, the riding wheel includes two wheel bodies, leaves the interval between two wheel bodies, the eddy current inspection probe is arranged in the interval between two wheel bodies.
The utility model has the advantages that: the cylinder liner product failure detection device of this scheme improves on prior art's basis, adopts the anchor clamps and the riding wheel combination of horizontal setting, guarantees that the cylinder liner rotates steadily, and in addition, the eddy current inspection probe adopts guide bar and riding wheel sliding fit, can guarantee that the clearance on probe and cylinder liner surface is fixed, improves the accuracy of detecting.

When detecting the internal defects of the cylinder liner, the end part of the cylinder liner is fixed by a centering fixture, the other end of the cylinder liner is contacted with a supporting wheel, a rotating shaft is started, the cylinder liner rotates at a constant speed, a servo motor is started at the same time, an eddy current flaw detection probe is driven to move at a constant speed, and spiral flaw detection is carried out on the inner surface and the outer surface of the cylinder liner. The distance between the guide rod and the probe is fixed, and the distance between the guide rod and the surface of the cylinder liner is fixed, so that the surface clearance between the probe and the cylinder liner can be determined to be fixed.
In the scheme, the workbench is provided with two opposite vertical seats 12, and the rotating shaft and the transverse sliding rail are respectively fixed on the two vertical seats. In addition, the riding wheel 8 comprises two wheel bodies, a space is reserved between the two wheel bodies, and the eddy current flaw detection probe 6 is positioned in the space between the two wheel bodies; similarly, the guide bar 10 and the guide hole 9 are also located between the two wheels.
