Description
Art
The present invention relates to a kind of method for designing of the cannot-harm-detection device, particularly relate to a kind of make detected pieces all the time along externally wearing type probe axis run method.
Background technology
Externally wearing type probe is the conventional detection probe in electromagnetic nondestructive equipment, is used for the online and off-line through mode testing of metal tube, rod, wire rod.Conventional externally wearing type probe adopts following structure usually, and magnetic test coil is fastened on coil winding skeleton outer peripheral face, and coil winding skeleton is fixed in probing shell.Externally wearing type probe is fixed on detection line, and tested metal tube, rod, wire rod are run by the central through hole of mechanical driving device through the coil winding skeleton in externally wearing type probe.In the ideal situation, i.e. tested metal tube, rod, the size shape of wire rod is regular, without in diastrophic situation, tested metal tube, rod, the axis twining the central through hole of skeleton along the coil in externally wearing type probe is run by wire rod, but due to the impact of present production process technical merit, tested metal tube, rod, wire rod is difficult to ensure without flexural deformation completely, when tested metal tube, rod, when there is flexural deformation in certain part of wire rod (even if these flexural deformations are less), tested metal tube, rod, the axis of the central through hole of the coil winding skeleton departed from externally wearing type probe is run by this part of wire rod, because electromagnetic detection coil sensitivity is higher, metal tube, rod, wire rod departs from axis and will cause magnetic test coil built-in field that larger change occurs, to larger fluctuation be there is in the detection signal of externally wearing type probe acquires, the undesired signal produced will have a strong impact on tested metal tube, rod, normally detecting of defect in wire rod.
Summary of the invention
The object of the invention is to the deficiency overcoming prior art, there is provided a kind of and make detected pieces all the time along the method that externally wearing type probe axis is run, by increasing one deck fluid bag parts in externally wearing type probe, even if realize certain part when there is flexural deformation of tested metal tube, rod, wire rod, tested metal tube, rod, wire rod also can the axis of central through hole of coil winding skeleton all the time in externally wearing type probe run.
The technical solution adopted for the present invention to solve the technical problems is: a kind of make detected pieces all the time along externally wearing type probe axis run method, increase one deck fluid bag between coil winding skeleton in externally wearing type probe and shell, a centering folder is fixed at the two ends of coil winding skeleton respectively; Described fluid bag can crimp, and coil winding skeleton can be moved along any direction perpendicular to axial direction, and the liquid in fluid bag is nontoxic, harmless, non-corrosiveness, nonflammable cryogenic liquid; Described centering folder can clamp detected pieces, and detected pieces is run all the time on the axis of externally wearing type probe coil winding skeleton; When detected pieces departs from original Runtime Infrastructure, detected pieces will drive the fluid bag outside coil winding skeleton extruding coil winding skeleton, together depart from original Runtime Infrastructure, and the axis that detected pieces can remain at coil winding skeleton is run; Because magnetic test coil is fastened at the outer peripheral face of coil winding skeleton, so detected pieces can be run all the time on the axis of magnetic test coil.
The invention has the beneficial effects as follows, there is provided a kind of and make detected pieces all the time along the method that externally wearing type probe axis is run, by increasing one deck fluid bag parts in externally wearing type probe, deformable when utilizing fluid bag stressed, revertible feature when not stressing, even if realize tested metal tube, rod, when there is flexural deformation in certain part of wire rod, tested metal tube, rod, wire rod also can all the time externally wearing type probe in coil twine the central through hole of skeleton axis run, efficiently solve online current, the difficult problem that examined workpiece centering in in-service through mode electromagnetic nondestructive runs, ensure the consistance of examined workpiece circumference detection sensitivity.
Below in conjunction with embodiment, the present invention is described in further detail, but a kind of method that detected pieces is run along externally wearing type probe axis all the time of the present invention is not limited to embodiment.

Embodiment
Embodiment as shown in Figure 1, Figure 2, Figure 3 shows, of the present invention a kind of make detected pieces all the time along externally wearing type probe axis run method, increase one deck fluid bag 3 between coil winding skeleton 1 in externally wearing type probe and shell 4, a centering folder 5 is fixed at the two ends of coil winding skeleton 1 respectively; Described fluid bag 3 can crimp, and coil winding skeleton 1 can be moved along any direction perpendicular to axial direction, and the liquid in fluid bag 3 is nontoxic, harmless, non-corrosiveness, nonflammable cryogenic liquid, such as water; Described centering folder 5 can clamp detected pieces 6, and detected pieces 6 is run all the time on the axis of externally wearing type probe coil winding skeleton 1; When detected pieces 6 departs from original Runtime Infrastructure, detected pieces 6 extrudes fluid bag 3 outside coil winding skeleton 1 by driving coil winding skeleton 1, together departs from original Runtime Infrastructure, and the axis that detected pieces 6 can remain at coil winding skeleton 1 is run; Because magnetic test coil 2 is fastened at the outer peripheral face of coil winding skeleton 1, so detected pieces 6 can be run all the time on the axis of magnetic test coil 2.Fig. 4 is the detection schematic diagram of conventional externally wearing type probe, and by comparing, the externally wearing type probe designed according to method for designing of the present invention is obviously better than conventional externally wearing type probe, solves detected pieces centering and runs the difficult problem detected.
Above-described embodiment is only used for further illustrating and of the present inventionly a kind ofly makes detected pieces all the time along the method that externally wearing type probe axis is run; but invention is not limited to embodiment; every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all fall in the protection domain of technical solution of the present invention.
