Embodiment Construction

[0049] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0050] see figure 1 , a quality inspection device for casting grinding, comprising 1, a computer; 2, a bus; 3, an image detection area mounting frame; 4, a gear belt; 5, an industrial CCD camera; 6, an optical projector; 7, a casting; 8, Vacuum sucker; 9. Conveyor belt; 10. Elevator. The vacuum chuck 8, the conveyor belt 9 and the elevator 10 constitute a transmission structure, the main function of which is to fix the just polished casting 7 on the vacuum chuck 8 according to the specified direction and position, and the vacuum chuck 8 is distributed and connected to the conveyor belt 9 at a certain distance. of the top.

[0051] During operation, the vacuum chuck 8 carries the casting 7 and moves slowly on the conveyor belt 9 for the purpose of moving the measured casting to the bottom of the image acquisition area device 3. At this time, the e...

Abstract

The invention discloses a casting quality test method and device and an application method of the device. The casting quality test device comprises three parts including a casting test conveying mechanism, a casting surface defect test device and a defect identification and classification mechanism, wherein the casting test conveying mechanism can be used for fixing a polished casting to be testedon a vacuum suction disc; the polished casting to be tested is conveyed into the casting surface defect test device through a conveyor belt; the device mainly applies a digital image processing technology, and a mounted industrial CCD (Charge Coupled Device) camera is used for acquiring an image; and a digital image processing algorithm designed on a background is used for carrying out defect identification on a casting surface polishing image. In an identification process, surface defect positions of the casting need to be obtained, and defect size and area also need to be calculated, so that defect grades are judged and classification of defect types is realized. A parameter report is generated according to a final identification result and a tested casting body is marked; and castingswith qualified polishing and castings with unqualified polishing are classified and output through the defect identification and classification mechanism.

Description

technical field [0001] The invention relates to a method, device and method for detecting the quality of casting surface grinding, in particular to the field of automation technology for testing and detecting system equipped with industrial cameras to replace manual operation for detecting the quality of castings Background technique [0002] The traditional grinding process detection is the application of manual detection. Based on personal experience, it is often inefficient to rely on naked eyes or palm touch to detect the grinding effect of castings. The workshop personnel are trapped by heavy working pressure and actually need non-destructive castings, so manual inspection cannot ensure that the quality inspection of castings can achieve the desired effect. Once a defect occurs, it will affect a series of problems such as subsequent casting assembly, and the casting Over-grinding or under-grinding is unavoidable in automatic production and grinding, which leads to defe...
