Casting polishing quality test method and device and application method of device

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...

Problems solved by technology

[0006] In order to overcome the burrs, over-polished depressions and under-polished protrusions that appear on the unqualified grinding surface of castings, and overcome the problem of low efficiency in traditional manual casting quality inspection, an efficient, accurate and automated casting is invented instead. Quality inspection method, device and method of use thereof
