Description
Technical Field
The invention belongs to the technical field of ultrasonic nondestructive testing, and particularly relates to an ultrasonic phased array automatic detection device for a disc-shaped workpiece.
Background
In the production and processing process of the gear disc of the automobile gearbox, various manufacturing defects can be inevitably generated due to objective factors such as welding process problems, welder operation problems or welder equipment problems. At present, the surface defects are generally measured by using visual and measuring tools, but unqualified products with the surface defects can be screened out only in a small amount, and the visual fatigue of finished products and workers is caused by long-term large-amount visual detection, so that the products are easy to loose and leak. In fact, more welding defects such as air holes, slag inclusion, incomplete fusion, incomplete penetration and the like exist inside the welding seam, the detection cannot be performed by visual means, and the influence of the internal defects on the quality of the product and the potential safety hazard caused by the internal defects are relatively more serious.
It is known that internal defects of gear welds are currently detected mainly by sampling destructive dissection, and whether a batch of samples is qualified is determined by observing the qualification of dissected samples. This method has several disadvantages:
1) for destructive testing, the process is complicated, time-consuming and labor-consuming. The gear workpiece is complex, high in strength and high in test difficulty, internal checking of all positions cannot be carried out at all, and defects of the qualified workpiece at the position which is not cut actually probably exist. After the test, the workpiece can not be put into use any more no matter whether the workpiece is qualified or not, and the detection cost is high.
2) The required time is long, and once sampling is unqualified, the whole batch of workpieces need to be scrapped, the cost is high, and the production efficiency is low.
3) The sampling is used to replace the whole, and the sampling quantity is small, so that the effective analogy cannot be realized. The sampling quantity is large, the cost is high, and the rejection rate is high. And sampling has errors, so that the quality of each product cannot be effectively guaranteed.
At present, the method possibly used for carrying out nondestructive detection on the internal defects of the gear welding seam mainly comprises the nondestructive detection of rays (X rays, gamma rays and the like): the detection result is visual. But the method is difficult to carry out on complex workpieces, and the method has the defects of radiation, harm to personal safety, larger equipment volume, complex detection process and the like. Because the gear welding seam has a special structure, the welding seam is blocked by a relatively thick gear, if a line film is adopted for shooting, the gear needs to be milled and then shot, and therefore, the operation cannot be performed at all on the type of gear welding seam by using a ray technology in practice.
