Body structure is described, and below with reference to Fig. 1-Fig. 5, is described in detail to the working principle of measuring device.
Level-one diaphragm 2 is fixed on bottom plate 12, and the aperture center as other secondary diaphragms 4 is to reference of reference.Due to limit
The diameter of through-hole 6 and the pore size of level-one diaphragm 2 match on position plate 11 and fixed plate 3, penetrate to remove to wear in light beam
Part except hole is shielded by level-one diaphragm 2 completely, and the diameter of the through-hole 6 on limit plate 11 and fixed plate 3 is just needed to be greater than one
The aperture of grade diaphragm 2.Therefore, Yao Shixian level-one diaphragm 2 can be replaced with actual conditions, just be needed on limit plate 11 and fixed plate 3
Through-hole 6 diameter be greater than all uses level-one diaphragm 2 aperture, but the diameter of through-hole 6 too greatly also will affect shielding dissipate
The quality of irradiating light beam, therefore preferably can also replace limit plate 11 and fixed plate 3 with level-one diaphragm 2.Limit plate 11 and bottom
It is bolted between plate 12, level-one diaphragm 2 is clipped between limit plate 11 and fixed plate 3, and passes through stove bolt for limit plate
11, level-one diaphragm 2 and fixed plate 3 are fixed.
It is more convenient accurate to be directed at the aperture center of multiple diaphragms, diaphragm regulating device 5 is set, so that secondary diaphragm
4 horizontal position and height are adjustable.Wherein, the adjusting of horizontal position can be selected that nut-screw rod is adjusted, electric sliding rail is mobile or
Other Level tune modes, measuring device selection provided in this embodiment are that simple nut screw is adjusted.The adjusting of height
The adjusting of Telescopic-cylinder bar, nut screw adjusting, telescope motor adjusting or other height adjustment modes can be selected, the present embodiment provides
Measuring device select also for simple nut screw adjust, and pass through the first height regulating frame 522 and the second height adjustment
Frame 523 will move horizontally and be converted to height adjustment.
Meanwhile secondary diaphragm 4 is fixed on diaphragm by the fixed part 531 and interconnecting piece 532 of the fixed bracket 53 of diaphragm and adjusts
In the top fixed plate 524 of device 5, wherein fixed part 531 is fixed in the fixed plate 524 of top, to make fixed part 531 and secondary
Grade diaphragm 4 is more securely attached, and the vertical section of fixed part 531 is L-type, and the horizontal component of fixed part 531 is fixed on top fixed plate
On 524, increase fixed part 531 and push up fixed plate 524 contact area, fixation it is stronger, the vertical portion of fixed part 531 with
Interconnecting piece 532 is connected by stay bolt 9, and secondary diaphragm 4 is clipped between interconnecting piece 532 and the vertical portion of fixed part 531, rotation
Stay bolt 9 can make interconnecting piece 532 therefore can replace secondary by adjusting stay bolt 9 far from or close to fixed part 531
Diaphragm 4 and the clamping degree for adjusting secondary diaphragm 4.
In the present embodiment, it carries out analyzing its course of work for using two secondary diaphragms 4.Firstly, according to specific
Actual demand, chooses suitable level-one diaphragm 2 and two secondary diaphragms 4, the secondary diaphragm 4 close to level-one diaphragm 2 are denoted as two
Grade diaphragm, the secondary diaphragm 4 far from level-one diaphragm 2 are denoted as three-level diaphragm, wherein the perforated hole diameter of three-level diaphragm is less than second level
The perforated hole diameter of diaphragm.And the diameter and the pore size phase of level-one diaphragm 2 of through-hole 6 are chosen according to level-one diaphragm 2
Then limit plate 11 is bolted to connection in one end of bottom plate 12, by level-one diaphragm by the limit plate 11 and fixed plate 3 matched
2 aperture center is directed at coincidence with the through hole center of limit plate 11, and is fixed on limit plate 11 using fixed plate 3,
During this, the through hole center of fixed plate 3 should also coincide with the aperture center of level-one diaphragm 2.Then pass through rotation stay bolt
9, so that interconnecting piece 532 is far from fixed part 531, until the spacing of interconnecting piece 532 and fixed part 531 can hold lower secondary light
Second level diaphragm is placed between interconnecting piece 532 and fixed part 531 by door screen, then rotating stay bolt 9 makes interconnecting piece 532 close to fixed
Portion 531, thus the second level diaphragm that is fixedly clamped.Then the first lead screw 512 is rotated by the first crank 7, so that the first feed screw nut
518 move on the first lead screw 512, and drive slider connecting plate 517 and vertical adjustment section 52 thereon, the fixed bracket 53 of diaphragm
It is moved horizontally with second level diaphragm, the horizontal position of coarse adjustment second level diaphragm, the second lead screw 527 is then rotated by the second crank 8 again,
So that the second feed screw nut 528 moves on the second lead screw 527, and drive second height hinged with the second feed screw nut 528
One end of adjusting bracket 523 moves, and the angle between the second height regulating frame 523 and horizontal direction changes, to adjust
Save the height of second level diaphragm.Wherein, to have guaranteed to fix the first height regulating frame 522 supported also therewith, top fixed plate 524
The second sliding rail 526 is additionally provided on bottom end, one end of the first height regulating frame 522 is in the second sliding rail 526 with the second height adjustment
The movement of one end of frame 523 and slide.And then the position by 8 accurate adjustment second level diaphragm of the first crank 7 and the second crank, make
The aperture center at the perforated hole center and level-one diaphragm 2 that obtain second level diaphragm coincides.Regulate second level diaphragm position and then
Three-level diaphragm is adjusted using the above method, so that the hole at the perforated hole center of three-level diaphragm, second level diaphragm and level-one diaphragm 2
Diameter center is overlapped.
Certainly, to simplify experimentation, original level-one diaphragm 2 in the measuring device can also be directly selected, is only replaced
Two secondary diaphragms 4.
Measuring device provided in an embodiment of the present invention, level-one diaphragm are primary shield, carry out limit beam and shield to dissipate to beam
Ray, the diameter that multiple secondary diaphragms reduce beam step by step can pass completely through ionisation chamber when beam being made to reach ionisation chamber.
This measuring device secondary diaphragm replaceable using pore size, expands the scope of application of the measuring device, experimental
It specifically is required to replace the corresponding diaphragm of pore size at any time, while to can be realized height adjustable for secondary diaphragm, it can be quick
It is directed at the aperture center of multiple diaphragms, is adjusted simply, it is easy to use.
Above-described specific embodiment has carried out further the purpose of the present invention, technical scheme and beneficial effects
It is described in detail, it should be understood that being not intended to limit the present invention the foregoing is merely a specific embodiment of the invention
