Non-destructive testing device for engine block

Abstract

The invention discloses a non-destructive detection device for an engine cylinder block, comprising: a support mechanism fixed on the cylinder port of the engine; a slide block mounted on the support mechanism and capable of rotating relative to the support mechanism; a spring seat mounted on the slide block And it is slidably connected with the slider, and the spring seat can feed and move relative to the slider in the horizontal direction; the telescopic rod is installed on the spring seat and can feed and move in the vertical direction relative to the spring seat, and the telescopic rod runs through the support mechanism One end of the probe is accommodated in the engine cylinder; the probe is detachably installed on the telescopic rod, the detection end of the probe is accommodated in the engine cylinder, and the probe is electrically connected to the signal receiving device; the encoder is installed on the support mechanism and its The rotating shaft is rotationally connected with the slider, and drives the rotating shaft of the encoder to rotate when the slider rotates, and the encoder is also electrically connected with the signal receiving device. The non-destructive testing device for the engine cylinder body has the advantages of high detection accuracy and high efficiency.

Description

technical field [0001] The invention relates to the field of detection devices for engine cylinders, in particular to a non-destructive detection device for engine cylinders. Background technique [0002] The cylinder block is an important part of the engine. It is subject to the combined effects of high temperature, high pressure and complex loads during operation, and is prone to various internal and external defects. If the engine block is decommissioned, it will lead to a waste of resources if it is directly returned to the furnace. At present, repair or remanufacturing processing technology is usually used to restore its performance and put it into use again. Remanufacturing refers to the industry that uses advanced technology to repair and transform waste equipment under the guidance of the product life cycle theory. The performance requirements of remanufactured products can meet or even exceed new products. Before remanufacturing the defective cylinder block, it is ...

Problems solved by technology

When using a hand-held probe, it is easy to shake when hand-held, so the stable position of the probe cannot be guaranteed.

At the same time, the magnetic memory probe needs to maintain a certain distance from the detection surface, and a sudden change in the distance will also affect the accuracy of the detection signal

In summary, the existing hand-held detection probes not only have low detection efficiency, but also cannot guarantee the detection accuracy
