Description

technical field [0001] The invention relates to the field of automated machinery, in particular to a machine vision-based processing system for flexible casting risers of hubs. Background technique [0002] The casting of aluminum alloy wheels for motorcycles in foreign countries emerged in the 1960s. At present, my country has become a major producer of aluminum alloy wheels for motorcycles. The casting methods used are mainly metal-type gravity casting and vacuum high-pressure casting. It is widely used because of low technical requirements and low investment; when metal mold gravity casting is poured, the fluid relies on gravity to flow and fill the mold. Since there is no external pressure, in order to obtain dense castings, it is often necessary to use the riser to feed the shrinkage, so , The aluminum alloy wheel blanks formed by metal gravity casting have heavier risers that need to be processed. [0003] The first process of rough machining of motorcycle aluminum allo...

Problems solved by technology

[0003] The first process of rough machining of motorcycle aluminum alloy wheel blanks is to cut the riser produced by casting, which is convenient for the subsequent finishing of the wheel hub. The current processing technology is to cut the riser with a saw blade, and the cutting reference plane is based on the bottom of the wheel hub. The surface is the reference plane, and the saw blade cuts the wheel riser along the cutting surface of the wheel hub. The motorcycle aluminum alloy wheel hub models are generally different in shape and size, so the processing equipment needs to have high flexibility to be compatible with different types of hubs; The diameter of the aluminum alloy wheel of the car is distributed from 10 inches to 19 inches. When cutting the hub riser, the tooling fixture of the equipment needs to be compatible with wheels of different sizes from 10 to 19 inches; The distance is different, and the distance parameters between the saw blade and the base surface are different during processing, so the tool parameters must be manually switched when processing different types of hubs; in summary, the existing processing equipment lacks adaptability to different types of hubs, which increases the Manual workload reduces the efficiency of machine tool processing
