Abstract
The utility model belongs to the technical field of the non -destructive inspection technique and specifically relates to a magnetism probe, include wafer and the voussoir that has an inclined plane, install on the inclined plane of voussoir the wafer, the through -hole has been seted up along the direction of wafer launching beam on the voussoir, the cross -section of its axis of through -hole perpendicular to with the shape of wafer is unanimous, the pouring has epoxy in the through -hole, the bottom surface of voussoir is seted up flutedly, be provided with in the recess rather than assorted magnet, the utility model discloses a magnetism probe packs the epoxy who costs an arm and a leg through offered the through -hole along the orientation of wafer transmission light beam on the inclined plane of voussoir in the through -hole, can improve the detection precision of probe on the one hand, so on the other hand is examining time measuring because what only adopt in the through -hole is that epoxy overall cost is relatively low, magnet can make probe absorption at workpiece surface.
Description
Technical field
The utility model relates to technical field of nondestructive inspection, especially a kind of magnetic probe.
Background technology
The propagation of vibration in elastic medium is called fluctuation, be called for short ripple, frequency is higher than the mechanical wave of 20KHz, be called ultrasound wave, when ultrasound wave by a kind of medium incident to another kind of medium time, because in two media, velocity of propagation is different, medium face can produce the phenomenons such as reflection, refraction and waveform transformation, probe can only launch the row wave beam suitable with probe wafer size, be the sensing range of this probe, angle probe is all got used to making wedge with organic glass, to form the sound wave incident angle needed for, and reaches the object of shape transformation.A two normal probe of one receipts type partition type and double oblique probe are also all using organic glass as sound penetrating wedge, this is because organic glass acoustical behavior is good, but its velocity of sound variation with temperature changes and easy to wear to some extent, so should often test the angle of probe and revise, epoxy resin acoustical behavior is good, but expensive, if adopt epoxy resin to make the high cost that wedge can cause angle probe, existing angle probe can not well and surface of the work fit.
Utility model content
The technical problems to be solved in the utility model is: in order to solve, existing probe can not well and surface of the work be fitted, wedge made by a kind of organic glass that adopts, but the velocity of sound variation with temperature of organic glass changes to some extent and the easy to wear and another kind of epoxy resin that adopts causes the deficiency of probe high cost as wedge, a kind of magnetic probe is now provided, it can easily machine-shaping, cost is low and acoustical behavior good, can be adsorbed on surface of the work.
The utility model solves the technical scheme that its technical matters adopts: a kind of magnetic probe, comprise wafer and the voussoir with an inclined-plane, described wafer is installed on the inclined-plane of described voussoir, described voussoir offers through hole along the direction of wafer launching beam, described through hole is consistent with the shape of described wafer perpendicular to the cross section of its axis, epoxy resin is cast with in described through hole, , the bottom surface of described voussoir offers groove, the magnet matched with it is provided with in described groove, in the place of the acoustic beam process that wafer is launched, but epoxy resin that acoustical behavior good more expensive by price, the detection accuracy of probe can be improved on the one hand, another aspect is that epoxy resin is so holistic cost is relatively low because of what only have the interior employing of through hole, magnet can make voussoir be adsorbed on surface of the work.
For the ease of processing, further, the material of described voussoir is organic glass, and organic glass is easy to machine-shaping.
The beneficial effects of the utility model are: magnetic probe of the present utility model by offering through hole along the direction of wafer transmitted beam on the inclined-plane of voussoir, expensive epoxy resin is filled in through hole, the detection accuracy of probe can be improved on the one hand, another aspect is that epoxy resin is so holistic cost is relatively low because of what only have the interior employing of through hole, when detecting, magnet can make probe be adsorbed on surface of the work.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the schematic diagram of the utility model magnetic probe.
In figure: 1, inclined-plane, 2, voussoir, 3, wafer, 4, through hole, 5, magnet.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
Embodiment 1
As shown in Figure 1, a kind of magnetic probe, comprise wafer 3 and the voussoir 2 with an inclined-plane 1, described wafer 3 is installed on the inclined-plane 1 of described voussoir 2, described voussoir 2 offers through hole 4 along the direction of wafer 3 launching beam, described through hole 4 is consistent with the shape of described wafer 3 perpendicular to the cross section of its axis, epoxy resin is cast with in described through hole 4, the bottom surface of described voussoir 2 offers groove, the magnet 5 matched with it is provided with in described groove, in the place of the acoustic beam process that wafer 3 is launched, but epoxy resin that acoustical behavior good more expensive by price, the detection accuracy of probe can be improved on the one hand, another aspect is that epoxy resin is so holistic cost is relatively low because of what only have the interior employing of through hole 4, when detecting, magnet 5 can make voussoir 2 be adsorbed on surface of the work.
The material of described voussoir 2 is organic glass, and organic glass is easy to machine-shaping.
Compared with prior art this probe by offering through hole 4 along the direction of wafer 3 transmitted beam on the inclined-plane 1 of voussoir 2, expensive epoxy resin is filled in through hole 4, the detection accuracy of probe can be improved on the one hand, on the other hand because only have adopt in through hole 4 be epoxy resin so holistic cost is relatively low, when detecting, magnet 5 can make probe be adsorbed on surface of the work.
Above-mentioned is enlightenment according to desirable embodiment of the present utility model, and by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on instructions, must determine its technical scope according to right.
Claims (2)
1. a magnetic probe, comprise wafer (3) and there is the voussoir (2) of an inclined-plane (1), it is characterized in that: the inclined-plane (1) of described voussoir (2) is upper installs described wafer (3), described voussoir (2) offers through hole (4) along the direction of wafer (3) launching beam, described through hole (4) is consistent with the shape of described wafer (3) perpendicular to the cross section of its axis, described through hole is cast with epoxy resin in (4), the bottom surface of described voussoir (2) offers groove, the magnet (5) matched with it is provided with in described groove.
