Embodiment 1

[0027] like Figure 1-3 The shown eddy current flaw detection device for defects in the inner wall of the engine cylinder liner includes a conveying mechanism 1 and a detection table 2 located at the discharge end of the conveying mechanism;

[0028] The upper end surface of the detection table 2 is provided with a V-shaped groove 21 for limiting the position of the cylinder liner 3, and the length direction of the V-shaped groove is consistent with the feeding direction of the conveying mechanism; The mounting frame 22 is fixedly connected with the testing table by screws; the mounting frame is provided with a clamping mechanism capable of moving the cylinder liner to the V-shaped groove, and a pressing force for fixing the cylinder liner in the V-shaped groove along the vertical direction The telescopic mechanism and the telescopic mechanism 4, the telescopic end of the telescopic mechanism is fixed with a flaw detection device 41 that can extend into the cylinder liner.

...

Embodiment 2

[0035] On the basis of Example 1, as figure 1 , 3 As shown in , 4 and 6, along the feeding direction of the conveying mechanism 1, the left and right sides of the detection table 2 are also symmetrically provided with a discharge slot 5 and a discharge mechanism 6. The edge of the V-shaped groove 21 is connected to the The edge of the material slot 5 is connected by the arc surface transition, so that the cylinder liner 3 can automatically roll down into the discharge slot more smoothly and smoothly, so as to ensure that the cylinder liner can obtain enough momentum to ensure that it can roll to the discharge Inside the slot; the discharging mechanism includes two horizontally arranged discharging cylinders 61 and a top block 62 fixedly arranged at the telescopic end of the discharging cylinder. The other side is pushed out and rolled down to the discharge slot along the curved surface.

[0036] Wherein, the top block 62 is also made of nylon material or rubber material, so ...

Embodiment 3

[0039]On the basis of Embodiment 1 or Embodiment 2, the eddy current flaw detection device for engine cylinder liner inner wall defects according to the present invention further includes a frame 7, and both the conveying mechanism 1 and the inspection table 2 are installed on the frame. surface, so that the conveying mechanism and the inspection table form an integral structure, so that the position between the conveying mechanism and the inspection table is fixed, so that the conveying mechanism and the inspection table maintain high positional accuracy. At the same time, it is also convenient to carry out the overall position adjustment and transportation according to the workshop production line, which improves the convenience of the overall position adjustment and transportation.

Abstract

The invention provides an eddy current flaw detection device for engine cylinder liner inner wall defects. The eddy current flaw detection device comprises a conveying mechanism and a detection table, a V-shaped groove used for limiting the cylinder sleeve is formed in the upper end face of the detection table, and a mounting frame fixedly connected with the detection table is erected above the V-shaped groove. A clamping mechanism capable of moving the cylinder sleeve to the V-shaped groove, a pressing mechanism for fixing the cylinder sleeve in the V-shaped groove in the vertical direction and a telescopic mechanism are arranged through the mounting frame, and a flaw detection device capable of stretching into the cylinder sleeve is fixed to the telescopic end of the telescopic mechanism. The cylinder sleeve is conveyed through the conveying mechanism, the finger cylinder of the detection table is used for carrying the cylinder sleeve, the flaw detection device is used for achieving automatic flaw detection on the cylinder sleeve, and the problems that existing cylinder sleeve detection is poor in automation degree and low in overall detection efficiency are solved.

Description

technical field [0001] The invention relates to the technical field of cylinder liner detection equipment, in particular to an eddy current flaw detection device for defects in the inner wall of an engine cylinder liner. Background technique [0002] If the cylinder liner product has internal defects such as microscopic cracks and blisters, it is easy to cause failure due to the high temperature and high pressure during use. Once the failure occurs, the engine will be weak in compression, difficult to start, and blue smoke or black smoke from the exhaust. The environmental protection performance becomes worse, and at the same time, it will also lead to the reduction of engine power and the deterioration of the dynamic performance, the increase of fuel and oil consumption, and the deterioration of the economic performance. [0003] However, the existing engine cylinder liner detection and detection methods are relatively simple, and the degree of automation is poor, which mak...
