Problems solved by technology

If these defects appear in the working engine, it is easy to cause the failure of the engine
In previous inspections, inspectors observed the cracks and blisters on the surface of the cylinder liner with naked eyes, but the internal defects and micro-cracks on the outer surface could not be observed by naked eyes, and could only be detected by destruction. This inspection method It is easy to cause misjudgment, and the detection efficiency is also very low

Embodiment Construction

[0013] Such as figure 1 The special eddy current flaw detector for cylinder liner shown in the figure includes eddy current flaw detector 1 and sliding guide rail 2. The sliding guide rail 2 is provided with a probe clamping device 3 that can slide along the sliding guide rail 2, and the clamping positions at the ends of the probe clamping device 3 are respectively The probe 5 of the eddy current flaw detector 1 corresponds to the position of the clamped cylinder liner 6 wall, and the self-centering cylinder liner clamp 7 for clamping the cylinder liner 6 is provided with a rotating mechanism. The main control system of the eddy current flaw detector 1 is also equipped with a defect signal alarm device. The probe clamping device 3 can be adjusted along the direction of the vertical sliding guide rail 2 . The probe clamping device 3 and the sliding guide rail 2 are driven by a servo motor, and the rotating mechanism is driven by a variable-speed variable-frequency motor. In t...

Abstract

The invention relates to a special eddy current flaw detector of a cylinder sleeve, comprising an eddy current flaw detector and a slide guide. Probe clamping devices are arranged on the slide guide and can slide along the slide guide. The end clamping positions of each probe clamping device are respectively provided with a probe of the eddy current flaw detector, and the probe corresponds to theposition of a clamped cylinder sleeve wall; a cylinder sleeve clamp used for clamping a cylinder sleeve is provided with a rotating mechanism; the probe clamping device can be regulated and arranged along the direction vertical to the slide guide; the slide guide is at least provided with two sets of probe clamping devices, and assorted cylinder sleeve clamps and rotating mechanisms are arranged;a main control system of the eddy current flaw detector is also provided with a flaw signal warning device. The invention has accurate detection, high efficiency and strong universal property, and thedetection quality is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of non-destructive testing, and in particular relates to a flaw detection instrument which performs non-destructive testing on the inner and outer circles of engine cylinder liners and outputs defect information. Background technique [0002] During the casting and machining process of the engine cylinder liner, due to the internal stress and clamping force of the material itself, it is easy to cause microscopic cracks and internal defects such as pores and sand holes formed during the casting process. As the heart part of the engine, the cylinder liner must withstand high pressure and high temperature while satisfying durability and fuel economy. If these defects appear in the working engine, it is easy to cause the failure of the engine. In previous inspections, inspectors observed the cracks and blisters on the surface of the cylinder liner with naked eyes, but the internal defects and micro-cracks on th...
