Semi-automatic AC/DC fluorescence magnetic prospecting set dedicated for connecting rod

Abstract

The invention relates to a semi-automatic AC / DC fluorescence magnetic prospecting set dedicated for a connecting rod, which is characterized by comprising a headstock, a tailstock and a middle frame, wherein the middle frame is arranged between the headstock and the tail stock; the headstock, tailstock and the middle frame are provided with a grip shaft respectively; the grip shaft is provided with a circumferential magnetization device and a longitudinal magnetization device; the grip shafts of the headstock and the tailstock are connected with an air cylinder; a motor-driven bull-chain device is respectively arranged between the headstock and the middle frame as well as between the tailstock and the middle frame; a magnetic suspension sprayer nozzle is arranged above the motor-driven bull-chain device; the rear end of the motor-driven bull-chain device is connected with a rotary platform; and the input ends of the rotary platform and a demagnetizer are arranged in a dark shed. The invention has the advantages of high work efficiency, good magnetization effect, convenient operation and reliable performance.

Description

technical field [0001] The invention relates to a special semi-automatic AC / DC fluorescent magnetic detection unit for connecting rods, which is used for magnetic particle flaw detection of internal combustion engine connecting rods with a length of 50-300 mm. Background technique [0002] The internal combustion engine is the heart of a car, and the connecting rod is an important part of the diesel engine. When the internal combustion engine is working, the connecting rod cooperates with the crankshaft to move at high speed to transmit power. If there are defects such as cracks caused by material quality and processing on the connecting rod, it may break during use and cause the machine to fail, endangering personal safety and causing economic losses. Therefore, it must be inspected for flaw detection during the manufacturing process of the connecting rod. From the perspective of fracture mechanics, the danger of surface defects is much higher than that of internal defects...

Problems solved by technology

[0004] The current commercially available general-purpose magnetic detectors equipped with head and tailstock chucks clamping conductive circumferential magnetization devices and yoke-type longitudinal magnetization devices are suitable for magnetic detection of connecting rods, but they are manually mounted and Cutting, and except for a very small number of magnetic detectors with double-circumferential magnetization power supply and double-head chuck device (such as the special configuration of TIEDE 600WE in Germany), only one workpiece can be magnetized at a time, even if the observation inspection and demagnetization are not carried out on the machine , a workpiece must also take 6-7 seconds on the machine, and the working cycle cannot meet the requirements of increasing production
