Forging gear damage detection assembly line equipment based on magnetic flux leakage signal

Abstract

Forge piece gear damage detection assembly line equipment based on magnetic flux leakage signals comprises a base, a cleaning unit, a magnetization unit, a magnetic flux leakage detection unit and a marking unit are sequentially arranged on the base, and a gear is clamped and fixed through a clamp unit. The cleaning unit, the magnetization unit, the magnetic flux leakage detection unit and the marking unit are connected in series through a conveying belt mechanism installed on the base and convey the clamp unit in sequence. A batch of gears are sequentially fixed to the cleaning station, the magnetizing station, the magnetic flux leakage detection station and the marking station along with the clamp unit to be automatically cleaned, magnetized, detected and marked, and meanwhile the gears are kept to rotate automatically. The gear detection device can adapt to gears of different sizes, highly automatic detection of batch gears can be achieved, the gear detection cost can be greatly reduced, and meanwhile the gear detection efficiency and accuracy can be greatly improved.

Description

technical field [0001] The invention relates to a gear damage detection device, in particular to a forging gear damage detection pipeline device based on a magnetic flux leakage signal. Background technique [0002] It is well known that in the machinery industry, gears are widely used. Gears are used in machines of all sizes. Gear transmission is one of the main forms of mechanical transmission. Crack failure is a serious failure form of gear failure. If the crack further expands, it may cause the gear teeth to fatigue and break, or even cause the complete failure of the entire gear, resulting in mechanical failure or even paralysis, which seriously affects the safe operation of the equipment, so the detection of gear defects is crucial. [0003] Magnetic flux leakage detection means that after the ferromagnetic material is magnetized, a leakage magnetic field is formed on the surface of the test piece due to defects on the surface or near the surface. Magnetic flux leakag...

Problems solved by technology

[0004] In the existing gear testing equipment, there is a lack of a complete set of assembly line equipment for non-destructive testing of gears using magnetic flux leakage testing technology, and it is also impossible to perform batch testing for gears of different sizes at the same time. Different gears also require different fixtures, which greatly increases In addition to the detection cost, the detection efficiency is not high
