Abstract

The invention provides a besides-star wheel magnetic detector. The besides-star wheel magnetic detector comprises a main machine body, wherein a linear guideway is arranged on the main machine body, a movable chuck coil device and a besides-star wheel workpiece bearing platform are both arranged on the linear guideway, the movable chuck coil device is arranged above the besides-star wheel workpiece bearing platform, a liquid collecting tank is arranged under the linear guideway, the lower part of a fixed chuck coil device having an inner spraying function is arranged in the liquid collecting tank, the fixed chuck coil device and the movable chuck coil device are coaxially arranged, an outer spraying head is arranged in the liquid collecting tank, the liquid collecting tank is connected with a magnetic suspension liquid tank, and an automatic charging and discharging mechanism is arranged on the side surface of the main machine body. According to the besides-star wheel magnetic detector, the disadvantages of the prior art are overcome, all besides-star wheels with various specifications can be sufficiently and uniformly magnetized under a condition that a tooling is not replaced, a workpiece can be automatically loaded and unloaded conveniently, and the besides-star wheel magnetic detector is safe and reliable, has low failure rate and can be inserted into an automatic production line of a factory.

Description

technical field

[0001] The invention relates to a magnetic detector for outer planetary wheels, which is used for magnetic particle flaw detection of outer planetary wheels of automobile parts, and belongs to the technical field of magnetic detectors. Background technique

[0002] The outer star wheel is the main part in the car drive shaft universal joint. If there are defects such as cracks caused by material quality and processing on the outer star wheel, the drive shaft may break during use, which can easily cause car crashes and fatal accidents. Therefore, it must be inspected for flaw detection during the manufacturing process of the outer planetary wheel. From the perspective of fracture mechanics, the risk of surface defects is much higher than that of internal defects of the same size, so the magnetic particle inspection equipment suitable for the detection of surface and near-surface defects of ferromagnetic materials is used by manufacturers as an important means...
