Abstract
Present invention uses a kind of groove structure of optical axis, which includes: the flat mouth groove for being located at optical axis end face and a groove being on axle body close to flat mouth groove side.The method have the benefit that: under the premise of not weakening optical axis support stiffness, using a kind of light and handy structure, keep optical axis easy to disassemble in blind hole.
Description
Technical field
The present invention relates to a kind of methods convenient for optical axis disassembly.
Background technique
In the prior art some parts are used to fix with the occasion of other parts, is often fixed using optical axis, but
It is using optical axis, especially minor diameter optical axis in some blind holes, optical axis cooperates precision higher due to its surface smoother,
Cause to remove relatively difficult.
Summary of the invention
The invention proposes a kind of structure convenient for optical axis disassembly, there is a flat mouth groove on optical axis top, close to top
Also there is a groove at position, is not on supporting portion, groove is not due to leaning on paraxial edge towards with flat mouth texturearunaperpendicular
It will affect the support stiffness of optical axis.In blind hole during installation using this optical axis, groove ends outwardly, in disassembly, are led to
The tools such as flat mouth screwdriver rotation top flat port recess is crossed, lateral grooves are adjusted to a suitable angle, in this way using very
Multiplexing tool can catch on lateral grooves, and optical axis is taken out.
The method have the benefit that: under the premise of not weakening optical axis support stiffness, using a kind of light and handy knot
Structure keeps optical axis easy to disassemble.
Detailed description of the invention
Fig. 1, plain shaft structure figure of the invention；
Fig. 2, exemplary application map；
Optical axis is adjusted to suitable angle when Fig. 3, application.
Specific embodiment
When there is service condition as shown in Figure 2, need to be inserted into blind hole with optical axis come fixed card buckle, at this time due to hole
Space it is very narrow, if using common optical axis, will be relatively difficult when dismantling optical axis, using the present invention, tearing open
When unloading, top flat port recess is rotated by tools such as flat mouth screwdrivers, lateral grooves are adjusted to a suitable angle (as schemed
Shown in 3), lateral grooves can be caught on using many tools in this way, optical axis is taken out.
Claims (1)
1. a kind of groove structure of optical axis, it is characterised in that: have a flat mouth groove at optical axis either end facet center, flat close to having
The side axle body of port recess has a groove, and direction is vertical with flat mouth groove direction；When using this optical axis in blind hole, groove
End outwardly, when disassembly, rotates top flat port recess by tools such as flat mouth screwdrivers, by lateral grooves be adjusted to one it is suitable
Angle can catch on optical axis lateral grooves using many tools in this way, optical axis is taken out.
