The utility model discloses an optical lens supporting seat which can reduce the assembly stress of an optical lens so as to ensure optical indexes. In addition, the utility model also discloses a laser optical system with the optical mirror supporting seat.
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The terms "first" and "second" are used below for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature.
With the development of laser technology, lasers are widely used in the field of material processing, and therefore, higher requirements are also put on the reliability and stability of the lasers.
The laser optical system includes a plurality of optical devices, which are typically assembled by means of screws or the like, constituting the entire laser system.
As shown in fig. 1, the optical lens support base includes a support base body 02, the support base body 02 has a receiving groove 03, and the optical device 01 is mounted in the receiving groove 03 by adhesion, so that the support base body 02 supports the optical device 01. The supporting seat main body 02 is provided with a threaded assembly hole 04, and the supporting seat main body 02 is fixedly connected with other parts through the cooperation of a threaded structure and the threaded assembly hole 04.
In some embodiments, the optical device 01 is a lens.
Since a force is generated between the screw fixing member and the screw fitting hole 04 during the assembly with the screw fitting hole 04, a stress is generated at the screw fitting hole 04. The generated stress is continuously transmitted to the accommodating groove 03, so that the stress of the optical device 01 installed at the accommodating groove 03 is uneven, and the optical device 01 generates internal stress.
In addition, since the optical device 01 and the supporting seat main body 02 are made of different materials, the supporting seat main body 02 is made of metal, and the optical device 01 is made of glass; the linear expansion coefficient of the metal is 110 x 10 -7/℃～230*10-7/DEG C, and the linear expansion coefficient of the glass is 40 x 10 -7/℃～90*10-7/DEG C, namely the two linear expansion coefficients are different. When the ambient temperature changes, the deformation degree of the two materials is different, and the thermal expansion or cold contraction of the metal generates acting force on the glass, so that the glass generates internal stress.
The specific material of the supporting seat main body 02 may be set according to different needs, and the above-mentioned linear expansion coefficient of only one metal is exemplified.
In the above-mentioned structural assembly mode, after the optical device 01 is subjected to the local acting force of the accommodating groove 03 of the supporting seat main body 02 and the internal stress caused by thermal expansion, the optical device 01 is deformed, and the optical performance of the device is further affected.
As shown in fig. 2 and 3, when the optical device 01 is mounted using the optical lens support of fig. 1, the optical device 01 is changed from the good lens surface shape of fig. 1 to the severe deformation of the lens surface shape.
Based on the above technical problems, as shown in fig. 4 and 5, an optical lens support base is disclosed in the embodiment of the present utility model, which includes a support base main body 3.
The support base body 3 has a receiving groove 2 for receiving the optical lens 1, and the support base body 3 has a screw fitting hole 4; a stress relief groove 5 is provided between the accommodation groove 2 and the screw fitting hole 4.
In some embodiments, the supporting seat body 3 is a metal structure, the optical lens 1 is a glass lens, and the specific material of the supporting seat body 3 can be set according to different needs.
According to the technical scheme, the stress release groove 5 is formed between the accommodating groove 2 and the threaded assembly hole 4, so that the stress transferred from the threaded assembly hole 4 to the accommodating groove 2 is released, and the deformation of the supporting seat main body 3 due to the pretightening force of threaded installation can be released at the stress release groove 5.
In some embodiments, the supporting seat main body 3 includes: a first stage 31 and a second stage 32.
Wherein the first stage 31 and the second stage 32 include, but are not limited to, being integrally formed, and the height of the first stage 31 is greater than the height of the second stage 32.
The first stage 31 has a receiving groove 2, the second stage 32 has a threaded fitting hole 4, and the stress relief groove 5 is located at the junction of the first stage 31 and the second stage 32.
The specific size and shape of the first stage 31 and the specific size and shape of the second stage 32 can be set according to different needs and are all within the scope of protection.
In some embodiments, the depth of the stress relief groove 5 is 1/3-1/2 of the height of the second stage 32 for better stress relief.
By setting the depth of the stress relieving groove 5 to 1/3 to 1/2 of the height of the second stage 32, the stress is reduced while ensuring the strength of the connection of the first stage 31 and the second stage 32. The support base body 3 is prevented from being broken at the stress relief groove 5 when assembled with the screw fitting hole 4 by the screw.
The depth of the stress release groove 5 may be selected according to the material of the support base main body 3, so that the strength of the support base main body 3 is ensured and the stress is reduced.
Since the stress relief groove 5 is located between the accommodating groove 2 and the screw fitting hole 4, in order to better reduce the transmission of stress, the position of the stress relief groove 5 along the direction of the connecting line of the accommodating groove 2 and the screw fitting hole 4 is set as follows:
The distance from the center line of the accommodating groove 2 in the vertical direction to the center line of the threaded fitting hole 4 in the vertical direction is 1/3-1/2.
Through the arrangement, the stress release groove 5 can be ensured to be positioned between the connecting line of the accommodating groove 2 and the threaded assembly hole 4, and the stress generated at the threaded assembly hole 4 can be released at the stress release groove 5 in the maximum amount in the process of transferring the stress to the accommodating groove 2.
In order to reduce the deformation amount of the supporting seat main body 3, in an alternative embodiment, the stress release groove 5 is arranged close to the threaded assembly hole 4, so that the transmission of stress and deformation can be blocked rapidly, and the stability of the accommodating groove 2 is ensured.
It should be noted that, the position of the stress relief groove 5 at the connection line between the accommodating groove 2 and the screw fitting hole 4 includes, but is not limited to, the above-mentioned position.
In some embodiments, the stress relief groove 5 may also be located at a position offset between the receiving groove 2 and the threaded fitting hole 4, i.e., the stress relief groove 5 does not fall on the line connecting the receiving groove 2 and the threaded fitting hole 4. For example, a plurality of stress relief grooves 5 which do not communicate may be arranged in the horizontal axis direction of the accommodation groove 2, or a plurality of stress relief grooves 5 may be arranged around the circumference of the screw fitting hole 4, as long as the manner in which the stress generated to the screw fitting hole 4 can be achieved is within the protection range.
As shown in fig. 6, the stress relief groove 5 penetrates the support base body 3 in a horizontal direction, which is the horizontal direction identified in fig. 6. The stress release groove 5 penetrates through the supporting seat main body 3, so that the stress generated by the threaded assembly hole 4 can be released, and the deformation of the accommodating groove 2 and the problem generated by the stress are effectively prevented.
The width of the stress relief groove 5 can be set according to different needs and is within the scope of protection.
In some embodiments, the optical lens 1 is a glass lens.
Since the optical lens 1 is a generally round cake-shaped lens, in some embodiments, the accommodating groove 2 is an arc-shaped groove for matching with the shape of the optical lens 1.
In order to adapt to the shape of the cake-shaped lens, the supporting seat body 3 has a rectangular structure and has a circular arc-shaped accommodating groove 2.
In some embodiments, the threaded fitting holes 4 are two and are symmetrically arranged with respect to the receiving groove 2. Accordingly, the stress relief grooves 5 are two and are symmetrically arranged with respect to the accommodation groove 2.
In a further embodiment, the accommodating groove 2 has an elastic layer 6 in the circumferential direction, and the optical lens 1 is mounted in the accommodating groove 2 through the elastic layer 6.
By providing the elastic layer 6, the deformation generated in the accommodating groove 2 can be prevented from being transmitted to the optical lens 1 by utilizing the elastic deformation.
An elastic adhesive layer is optional for the elastic layer 6, and the elastic adhesive layer adheres to the circumference of the accommodating groove 2 and the optical lens 1.
It will be appreciated by those skilled in the art that the elastic layer 6 may also be an elastic rubber layer. The elastic rubber layer is arranged along the circumferential direction of the accommodating groove 2 and is fixed on the circumferential direction of the accommodating groove 2, and the elastic rubber layer is provided with a clamping groove for clamping and fixing the optical lens 1.
Through the arrangement, in order to reduce the acting force on the lens due to the fact that the linear expansion coefficient difference between metal and glass is large when the ambient temperature of the supporting seat main body 3 changes, the elastic layer 6 is selected, and a certain buffering effect can be achieved between the supporting seat main body 3 and the optical lens 1.
In addition, since the transmission of the assembly stress of the support base body 3 to the optical lens 1 is reduced, a series of performance indexes such as the adhesive strength, the temperature impact resistance, the collision resistance and the like of the optical lens 1 can be improved, and the stability and the reliability of the optical device can be improved.
As shown in connection with fig. 2, 3 and 7, by comparing the support base body 3 having the stress relief groove 5 in the present application with the support base body in fig. 1, the degree of influence on the surface shape of the lens when the assembly screw is fixed to the base plate.
Wherein, the support base main body which is not fixed by the screw is good in the surface shape of the lens in fig. 2; the support base body fixed by the screw and without the stress release groove, the surface shape of the lens in fig. 3 is seriously deteriorated; the base body is screwed and has a stress relief groove, the bottom of the lens in fig. 7 being slightly deformed.
Taken together, it is shown that: the influence degree of the supporting seat main body 3 on the surface shape of the lens is obviously smaller than that of the supporting seat main body in the figure 1, and the acting force on the lens is obviously reduced.
By combining the analysis, the supporting seat main body 3 has the advantages of simpler structure, easy processing and production and lower cost; compared with a flexible structure lens seat with a complex structure for a scientific research laboratory, the low-stress support seat main body 3 is higher in reliability, economical and practical, and suitable for industrial industrialized application.
In addition, the application also discloses a laser optical system comprising the optical lens supporting seat, wherein the optical lens supporting seat is the optical lens supporting seat disclosed in the embodiment, so the laser optical system with the optical lens supporting seat also has all the technical effects, and the technical effects are not repeated here.
