Abstract
A magnetic particle inspection device of a bearing steel ball is characterized by comprising a steel ball clamping part and an inspection main part, wherein the steel ball clamping part is fixedly connected with the inside of the inspection main part, and the curve of the steel ball clamping part is in a cambered surface shape and smaller than a hemisphere. The magnetic particle inspection device of the bearing steel ball has the advantages of being capable of clamping the bearing steel ball stably, simple in device structure and low in cost, and having good inspection effect and high inspection efficiency, and can be used for magnetic particle inspection of steel balls or other spherical parts for bearings of aircraft engines.
Description
Technical field
The utility model relates to non-destructive detecting device structure field, particularly a kind of magnetic powder inspection device of bearing steel ball.
Background technology
The engine magnetic powder inspection is primarily aimed at parts such as bearing with ferrimagnet, gear, and the shape of these parts is rule, and length-diameter ratio is usually greater than 3.Less than 3 part, especially bulb, there is big difficulty in length-diameter ratio when adopting magnetic powder inspection, needs to adopt special device to realize.Under the prolonged and repeated effect of cycle pulsation contact pressure, piece surface is prone to produce defective engine bearing, carries out regular nondestructive examination so tackle it with steel ball.The mode of magnetization that in the past adopted is that steel ball is put along rectilinear direction; To increase its length-diameter ratio, through the flaw detection of coil magnetizing completion part, the shortcoming of this mode is that the clamping of steel ball is unstable; The magnetization poor effect; Cause the flaw detection sensitivity of part to descend, the detection probability of defective is on the low side, is unfavorable for guaranteeing the reliability of steel ball magnetic powder inspection.
The utility model content
The purpose of the utility model is in order to have solved the problem that the steel ball clamping is unstable, the location is inaccurate, and the spy provides a kind of magnetic powder inspection device of bearing steel ball.
The utility model provides a kind of magnetic powder inspection device of bearing steel ball, it is characterized in that: the magnetic powder inspection device of described bearing steel ball comprises steel ball retained part 1, flaw detection main part 2; Wherein: steel ball retained part 1 is connected with the internal fixation of flaw detection main part 2, and the curve form of steel ball retained part 1 is a cambered surface, less than hemisphere.
Described steel ball retained part 1 is an elastic component.
Described steel ball retained part 1 is two chip architectures.
The advantage of the utility model:
The magnetic powder inspection device of the described bearing steel ball of the utility model; Can realize stable holding to steel ball, device structure is simple, and cost is low; Have good flaw detection effect and higher flaw detection efficient, can be used in the magnetic powder inspection of aeromotor steel bearing balls or other bulb.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:
Fig. 1 is the magnetic powder inspection device theory structure synoptic diagram of bearing steel ball.
Embodiment
