Abstract
The utility model proposes 56 sealing cap elevation carrection fixtures of TO, can be used for fixation of 56 lasers of TO when measuring sealing cap size, and laser sealing cap is fixed as horizontal attitude by the fixture with magnetic absorption member；The magnetic absorption member includes the rectangular magnet block of two high-precision sizes；The rectangular magnet block is supported and is stood vertically with holder；Two rectangular magnet blocks connect the magnetic face to be formed for adsorbing laser sealing cap at its angle end；This product energy is easy, is accurately measured to the sealing cap of TO56 lasers height.
Description
Technical field
The utility model is related to optical communication equipment technical fields, especially TO-56 sealing caps elevation carrection fixture.
Background technology
TO56 lasers need to measure it monitoring to ensure the consistency of product, especially in sealing cap in encapsulation process
Afterwards, need that the height after sealing cap is measured and confirmed, to ensure the consistency of focal length, so need to sealing cap height this
Parameter is measured and is monitored, and is had higher requirements to the accuracy of data in measurement and monitoring, and the precision of measured material
It needs to ensure, it is also necessary to which certain simplification is convenient for measuring operation；How to solve, is a research direction.
Invention content
The utility model proposes TO-56 sealing cap elevation carrection fixtures, can it is easy, accurately to the sealing cap of TO56 lasers
Height measures.
The utility model uses following technical scheme.
TO-56 sealing cap elevation carrection fixtures can be used for fixation of the TO-56 lasers when measuring sealing cap size, the folder
Laser sealing cap is fixed as horizontal attitude by tool with magnetic absorption member；The magnetic absorption member includes the rectangular magnet of two high-precision sizes
Block；The rectangular magnet block is supported and is stood vertically with holder；Two rectangular magnet blocks connect to being formed for adsorbing at its angle end
The magnetic face of laser sealing cap.
Described two rectangular magnet blocks are the square magnet piece of identical dimensions.
The holder is the T shape framves to stand upside down.
The pedestal of the T shape framves of the handstand is flatness in 5um planes below, the vertical component and horizontal part of T shape framves
The angle divided is 90 ± 0.05 °, and T shapes frame fixes rectangle magnet piece with its vertical component and is allowed to stand vertically.
The magnetic face is in M shapes, among the M shapes magnetic face lower recess be for house the section of sealing cap rear portion pin at
The slot at right angle.
The advantages of this product, is that it is horizontal attitude that conveniently securely laser component absorption, which can be limited, and it is accurate to be convenient for
Sealing cap elevation carrection, and be hardly damaged laser component.
This product with the holder of bottom high-flatness due to carrying out fixed magnet block, and the size of magnet piece is high-precision
, therefore can ensure the fixed pose severity of sealing cap, to advantageously ensure that accuracy of measurement.
Description of the drawings
With reference to the accompanying drawings and detailed description to the further details of explanation of the utility model：
Attached drawing 1 is the schematic diagram at TO-56 laser sealing caps position；
Attached drawing 2 is the schematic diagram of the utility model；
Attached drawing 3 is the schematic diagram of the utility model absorption TO-56 laser sealing caps；

Specific implementation mode
As shown in Figs. 1-3, TO-56 sealing caps elevation carrection fixture can be used for TO-56 lasers when measuring 1 size of sealing cap
Fixation, laser sealing cap 1 is fixed as horizontal attitude by the fixture with magnetic absorption member；The magnetic absorption member includes two high-precision rulers
Very little rectangular magnet block 3；The rectangular magnet block 3 is supported and is stood vertically with holder 4；Two rectangular magnet blocks 3 are at its angle end
Connect the magnetic face 5 to be formed for adsorbing laser sealing cap.
Described two rectangular magnet blocks are the square magnet piece of identical dimensions.
The holder 4 is the T shape framves to stand upside down.
The pedestal of the T shape framves of the handstand is flatness in 5um planes below, the vertical component and horizontal part of T shape framves
The angle divided is 90 ± 0.05 °, and T shapes frame fixes rectangle magnet piece with its vertical component and is allowed to stand vertically.
The magnetic face 5 is in M shapes, and the lower recess in M shapes magnetic face centre is the section for housing sealing cap rear portion pin 2
Slot at a right angle.
Embodiment：
The sealing cap position of TO56 lasers is placed on sealing cap elevation carrection fixture, its pin position 2 is made to be positioned over M shapes
Recess under the centre in magnetic face, magnetic face automatic absorbing sealing cap are allowed to bottom and are pressed in magnet piece front, and entire and base plane is flat
Entire fixture, is then placed in Quadratic Finite Element measuring apparatus or other measuring apparatus and measures, can measure sealing cap height by row.
