Embodiment
The one exemplary embodiment of the present invention is described hereinafter in connection with accompanying drawing.For clarity and conciseness,
All features of actual embodiment are not described in the description.It should be understood, however, that developing any this actual implementation
It must be made during example much specific to the decision of embodiment, to realize the objectives of developer, for example, symbol
Those restrictive conditions related to system and business are closed, and these restrictive conditions may have with the difference of embodiment
Changed.In addition, it will also be appreciated that although development is likely to be extremely complex and time-consuming, to having benefited from the present invention
For those skilled in the art of disclosure, this development is only routine task.
Herein, it is also necessary to which explanation is a bit, in order to avoid having obscured the present invention because of unnecessary details, in the accompanying drawings
It illustrate only and according to the closely related apparatus structure of the solution of the present invention and/or processing step, and eliminate and the present invention
The little other details of relation.
As shown in figure 1, the embodiment provides laser displacement sensor range unit, in laser displacement sensor
Range unit top is provided with sensor lock chamber 1, and laser displacement sensor 2 is installed in the inside of sensor lock chamber 1, and by upper end cover
9 are bolted.Air cooling chamber 3 is externally provided with sensor lock chamber 1, laser displacement is passed to by whole outer wall for cooling down
The temperature of sensor 2.It is lens mount 5 in the bottom of air cooling chamber 3, is connected by second flange disk with air cooling chamber 3, plane
Lens 4 are in 5 tilted placement of lens mount, to cut off contacting for laser displacement sensor camera lens and external environment.Lens
The upper end inside cavity of installed part 5 requires that the interference of planar lens reflected light can be eliminated by aoxidizing black processing.Under lens mount 5
Portion, it is connected by the 3rd ring flange with connector 7, the side wall of connector 7 is provided with air blow valve port 6, and blow valve port 6 is against planar lens
4 lower surfaces, the lower surface adhesive dust of planar lens 4 is prevented, air is blown out along bottom connector 7 can both ensure testee surface
Do not fall ash and dust under more dust environments around can be prevented to rest in connector.Increase asbestos board among every section of component connection,
The coefficient of heat conduction can be reduced and make cooling lighter so as to reduce the requirement of source of the gas tolerance.The bottom of connector 7 passes through first flange disk 8
It is fixed on testee environment outer wall.
Although disclosed embodiment is as above, its content is only to facilitate understand the technical side of the present invention
Case and the embodiment used, are not intended to limit the present invention.Any those skilled in the art to which this invention pertains, not
On the premise of departing from disclosed core technology scheme, any modification can be made in the form and details of implementation and is become
Change, but the protection domain that the present invention is limited, the scope that must be still limited by appended claims are defined.
