Problems solved by technology

It is not difficult to see from the measurement steps of the above comparative measurement method that when testing the reflectivity of a single target to be measured, it is necessary to measure the reflected power of the two material plates in sequence, which increases the difficulty of placement virtually. Placement accuracy puts forward higher requirements

Embodiment 1

[0034] like figure 1 and figure 2 As shown, the three-degree-of-freedom magnetic tooling structure for reflectivity testing provided by the embodiment of the present invention includes a fixed plate 1, a pitch adjustment plate 2, an azimuth adjustment plate 4 and a magnetic base 6, wherein the pitch adjustment plate 2 passes through the pitch rotation axis 3 is fixed on the fixed plate 1, and the pitch rotating shaft 3 enables the pitch adjusting plate 2 to rotate relative to the fixed plate 1 in pitch. One end of the azimuth adjustment plate 4 is rotatably fixed on the pitch adjustment plate 2 through the azimuth shaft 5, and the axial direction of the azimuth shaft 5 is perpendicular to the axial direction of the pitch shaft 3, and the magnetic base 6 is rotatably fixed through the roll shaft 7 At the other end of the azimuth adjustment plate 4 , the axis of the roll axis 7 is perpendicular to the axis of the azimuth axis 5 . Wherein, an electromagnet (not shown) is arran...

Embodiment 2

[0048] like Figure 5 As shown, the second embodiment is basically the same as the first embodiment, and the similarities will not be repeated. The difference is that the working surface 62 includes two rectangular planes and a concave surface arranged between the two rectangular planes. Since the material to be tested The flatness of the plate attachment is relatively high, so there are certain requirements for the flatness of the working surface 62, and the entire working surface 62 is processed with high precision, and the processing operation is difficult. In this embodiment, the working surface 62 There are rectangular planes on both sides, and a concave surface between the two rectangular planes (that is, not in contact with the material plate to be tested). The material plate to be tested is in contact with the two rectangular planes, so that the material plate to be tested can be flat and attached. Reduce the processing difficulty of the working face.

Embodiment 3

[0050] like Image 6 As shown, the second embodiment is basically the same as the above-mentioned embodiment, and the similarities will not be repeated. The difference is that a first dial 14 is sleeved on the azimuth rotating shaft 5, which is used to display the adjustment amount of the azimuth adjustment plate ( rotation angle), and according to different reading methods, the first dial 14 can be fixed on the pitch adjustment plate 2, or can rotate together with the azimuth shaft 5, or the second dial 15 can be sleeved on the roll shaft 7 , used to display the amount of rotation (rotation angle) of the magnetic base 6, according to the difference in reading mode, the second dial 15 can be fixed on the azimuth adjustment plate 4, and can also rotate together with the rolling shaft 7.

[0051] In some preferred embodiments, the first dial 14 and the second dial 15 can also be sleeved on the azimuth shaft 5 and the roll shaft 7 respectively.

[0052] In some preferred embodim...

Abstract

The invention relates to a three-degree of freedom magnetic tool structure for a reflectivity test; the tool structure comprises a fixed plate, a pitching adjusting plate, an orientation adjusting plate and a magnetic seat; the pitching adjusting plate is fixed on the fixed plate via a pitching rotary shaft; the pitching rotary shaft enables the patching adjusting plate to rotate with respect to the fixed plate; one end of the orientation adjusting plate is rotatably fixed on the pitching adjusting plate via an orientation rotary shaft; the axial direction of the orientation rotary shaft is vertical to that of the pitching rotary shaft; the magnetic seat is rotatably fixed on the other end of the orientation adjusting plate via a roll rotary shaft; the axial direction of the roll rotary shaft is vertical to that of the orientation rotary shaft; the magnetic seat has an electromagnet an electromagnetic switch that controls the electromagnet, and is used for sucking a to-be-tested magnetic material sheet or a magnetic metal plate that allows the to-be-tested material to attach to onto a work plane; the tool structure can place, position and re-place the to-be-tested material with a high precision, thus reducing operation requirements on operators, and reducing artificial factor influences.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to a three-degree-of-freedom magnetic tooling structure for reflectivity testing. Background technique [0002] Reflectivity is an inherent property of a material, which represents the value of the power of an object reflecting the incoming wave. As an important part of research on stealth materials and wave-absorbing materials, reflectivity testing occupies a large proportion in various tests in darkrooms. This kind of test mostly takes the material board as the main research object. Although the placement of the material board seems simple, it actually requires a high degree of precision for the workers to place the material board and the proficiency of the relevant personnel, especially in multi-band, In continuous frequency sweep and mass testing, the consistency of plate placement directly affects the connection error of the frequency sweep curves in each frequency band. ...
