Abstract
The utility model discloses a protective device for a through type eddy current detection probe. The protective device is characterized by comprising a mounting seat for mounting a probe in a clamped manner, wherein the mounting seat has threaded mounting holes corresponding to the two ends of a probe through hole respectively, nuts are assembled in both threaded mounting holes, a hard alloy guide sleeve which is arranged to be coaxial with the through hole is arranged at each of the two ends of the probe through hole, the hard alloy guide sleeves are tightly pressed at the end parts of the through hole by the nuts, and at least two hard alloy guide sleeves are arranged at a tubing inlet end of the through hole. The protective device disclosed by the utility model can be used for ensuring that positional deviation between the probe and the guide sleeves can not occur in a use process; the probe damage caused by the friction between tubing wall and the through hole wall is prevented and the service life of the probe is prolonged; circumferential deviation of tubing detection sensitivity is prevented and the quality of the detected tubing is ensured; and the protective device can be used for ensuring that the tubing does not deviate from the central line when a tube threading process starts, and the possibility of directly damaging the probe by shoveling at the moment when a shoe passes through the probe is prevented.
Description
Technical field
The utility model relates to through mode eddy current probe technical field, specifically refers to install the protective device of probe.
Background technology
Through mode eddy current probe (be called for short probe) is the part of eddy current flaw detec, for detection of one of Non-Destructive Testing instrument of various metal vertical bar tubing and whole pipe crimping material defective, is a kind of easy loss product.Probe is to be sealed with magnetic test coil in a polyamide skeleton or nonconducting skeleton, and skeleton has a perforation, and magnetic test coil evenly distributes along the perforation perisporium, and probe is once damage, just must whole scrapping, can't change magnetic test coil.Also need certain cost even change magnetic test coil.
According to eddy current test characteristic and technical requirement thereof, when tubing was carried out carrying out flaw detection, the general probe piercing aperture of selecting was than between the big 0.5mm-2.5mm of tube outer diameter.Traditional through mode eddy current probe is when detecting tubing, it is the orienting sleeve that adds a nylon or metal in the probe front, orienting sleeve and probe are independent being fixed on the frame respectively, and in actual use, the vibrations of machine and collision all can cause both position deviation to occur.When tubing by when probe because tubing and perforation decentraction, the hole wall phenomenon of pipe friction perforation appears, it is bad to cause probe to wear and tear faster, a general probe is the longest can only to use half a year; And can cause the circumferential detection sensitivity deviation of tubing, near the there detection sensitivity height of hole wall, the there detection sensitivity that departs from hole wall is low, has the possibility of mistake omission like this, can not guarantee to detect the quality of tubing.Because only adopt an orienting sleeve, being difficult to assurance tubing passes by along center line when passing probe all the time, particularly when tubing begins to bore a hole, the easy deviation of the head of tubing, the meeting disalignment, in the moment that tube head passes through probe, the possibility that tube head directly shovels bad probe can appear, and directly damage causes popping one's head in.Therefore be necessary to research and develop a kind of accurate guide-localization that passes through tubing, reached the protective device of protection probe this purpose.
The utility model content
The technical problems to be solved in the utility model provides a kind ofly can carry out accurate guide-localization with the protective device of protection probe to tubing.
For solving the problems of the technologies described above the technical scheme that adopts: a kind of protective device of through mode eddy current probe; it is characterized in that: include in order to clamp the probe mounting seat; mount pad offers threaded mounting hole respectively corresponding to the two ends of probe perforation; threaded mounting hole all is fitted with nut; the two ends of probe perforation are respectively equipped with the wimet orienting sleeve with the coaxial setting of boring a hole; the wimet orienting sleeve is pressed on the end of perforation by nut, and the tubing inlet end of its middle punch is provided with at least two cover wimet orienting sleeves.
On the basis of the above, the internal diameter of described wimet orienting sleeve is than the big 0.10mm-0.35mm of external diameter of tubing.
The beneficial effect that adopts the utility model to bring: because the utility model all is fixed on through mode eddy current probe and wimet orienting sleeve in the mount pad, guaranteed that probe and orienting sleeve in use position deviation can not occur, probe perforation and orienting sleeve remain coaxial position, avoid damaging probe because of the hole wall of tube material and tube wall friction perforation, prolong the serviceable life of popping one's head in, and can guarantee tubing walk all the time the perforation center line on, avoid the detection sensitivity of tubing circumferential deviation to occur, guarantee to detect the quality of tubing.At least two cover wimet orienting sleeves that the tubing inlet end of perforation is provided with are to have utilized two point location principles, guarantee when the beginning poling not disalignment of tubing, avoid appearing at the direct possibility of the bad probe of shovel of the moment of tube head by probe.
Description of drawings
Fig. 1 is the structural representation of the protective device of the utility model through mode eddy current probe.
Embodiment
As shown in Figure 1, a kind of protective device of through mode eddy current probe includes in order to clamp the mount pad 2 of probe 1, and mount pad 2 offers threaded mounting hole respectively corresponding to the two ends of probe 1 perforation 1.1, and threaded mounting hole all is fitted with nut 3.The two ends of probe 1 perforation 1.1 are respectively equipped with the wimet orienting sleeve 4 with the 1.1 coaxial settings of boring a hole, and wimet orienting sleeve 4 is pressed on the end of perforation 1.1 by nut 3.The tubing inlet end of its middle punch 1.1 is provided with at least two cover wimet orienting sleeves 4, reason is excessive with the contact area of wimet orienting sleeve 4 in testing process for fear of tubing 5, usually the endoporus of orienting sleeve 4 is provided with the footpath that width is not more than the 3mm shiny surface and is with 4.1, the at least two cover wimet orienting sleeves 4 that are provided with, be to have utilized two point location principles, guarantee at beginning tubing 5 disalignment not during poling.In order to guarantee the bearing accuracy of wimet orienting sleeve 4, the internal diameter of wimet orienting sleeve 4 is than the big 0.10mm-0.35mm of external diameter of tubing.Pop one's head in 1 perforation, 1.1 internal diameter then according to routine than the big 0.5mm-2.5mm of tube outer diameter.
Through mode eddy current probe 1 and wimet orienting sleeve 4 are all fastened in mount pad 2 by nut 3,2 of mount pads are fixed on the frame, can make probe 1 and orienting sleeve 4 in use position deviation can not occur all the time, and at least two cover wimet orienting sleeves 4 that 1.1 the tubing inlet end of boring a hole is provided with, can guarantee that more the center line straight line along probe 1 perforation 1.1 passes all the time at beginning tubing disalignment not during poling.After tested, the through mode eddy current probe that adopts the utility model to install at least can be with more than 5 years, and the life-span improves more than 10 times.
