Detailed Implementation
[0032] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.
[0033] The following is for reference. Figures 1-5 This application describes a three-dimensional adjustable optical frame according to an embodiment of the present application.
[0034] like Figures 1-3 As shown, this application embodiment provides a three-dimensional adjustable optical frame 100, including: a lens base 1, a bracket 2, a support base 3, a first position adjustment component 4, a second position adjustment component 5, and a third position adjustment component (including a third threaded pair 61 and a third return spring 62); wherein the lens base 1 is provided with an optical lens 11 mounting position 10 for mounting the optical lens 11; the bracket 2 is provided with a lens base 1 mounting cavity 21 and a base 22, the lens base mounting cavity 21 is used to mount the lens base 1, and the base 22 is used to support and fix the bracket 2; the support base 3 is detachably mounted on the base 22 of the bracket 2; wherein the lens base 1 is adjustablely mounted in the lens base mounting cavity 21 of the bracket 2 via the first position adjustment component 4 and the second position adjustment component 5, and the third position adjustment component is mounted on the support base 3 along a third direction and abuts against the bracket 2. The optical frame 100 provided in this embodiment achieves three-dimensional adjustment of the optical lens through a first position adjustment component 4, a second position adjustment component 5, and a third position adjustment component acting in different directions. This facilitates the output of light through different optical paths, is simple to operate, has good stability, and can adapt to the needs of different laser application scenarios. The optical lens 11 is not particularly limited and can be various optical lenses such as convex lenses, concave lenses, and mirrors.
[0035] In some embodiments, the first position adjustment assembly 4 includes a first threaded pair 41 and a first return spring 42 disposed opposite to each other in a first direction of the mirror base 1; the second position adjustment assembly 5 includes a second threaded pair 51 and a second return spring 52 disposed opposite to each other in a second direction of the mirror base 1; and the third position adjustment assembly is provided with a third threaded pair 61 and a third return spring 62 disposed in a third direction of the mirror base 1.
[0036] It is understandable that the first, second, and third directions are different, thus enabling position adjustment in three different directions.
[0037] In some implementations, the first direction is perpendicular to the second direction, and the third direction is perpendicular to the plane containing the first and second directions. For example, as... Figure 2 As shown, in some specific embodiments, the first position adjustment component 4 is arranged vertically on the plane where the optical lens 11 is located. The first threaded pair 41 is installed in the threaded hole on the upper surface of the bracket 2 and abuts against the upper surface of the lens base 1. The first return spring 42 abuts against the gap between the lower surfaces of the bracket 2 and the lens base 1 relative to the first threaded pair 41. Thus, when the first threaded pair 41 is adjusted, the lens base 1 between the first threaded pair 41 and the first return spring 42 increases or decreases the pressure on the first return spring 42, thereby extending or compressing the first return spring 42, and thus realizing the displacement of the lens base 1 in the vertical (up and down) direction.
[0038] Furthermore, such as Figure 1 As shown, the second position adjustment component 5 is arranged horizontally on the plane where the optical lens 11 is located. The second threaded pair 51 is installed in the threaded hole on the side of the bracket 2 and abuts against the side of the lens mount 1. The second return spring 52 abuts against the gap between the opposing sides of the bracket 2 and the lens mount 1 relative to the second threaded pair 51. Thus, when adjusting the second threaded pair 51, the pressure on the second return spring 52 can be increased or decreased through the lens mount 1 between the second threaded pair 51 and the second return spring 52, thereby extending or compressing the second return spring 52, and thus achieving displacement of the lens mount 1 in the horizontal (left-right) direction. In some embodiments, the second threaded pair 51 is located on the left side of the bracket 2 of the lens mount 1, in which case the second return spring 52 abuts against the gap between the right side of the lens mount 1 and the bracket 2; or the second threaded pair 51 is located on the right side of the bracket 2 of the lens mount 1, in which case the second return spring 52 abuts against the gap between the left side of the lens mount 1 and the bracket 2. It can be understood that the left or right side of the frame is not specifically defined, but is only a distinction in description, and can be defined by the direction when the operator faces the plane where the optical lens 11 is located.
[0039] In some embodiments, the third position adjustment component is arranged perpendicular to the plane where the optical lens 11 is located, the third threaded pair 61 is disposed on the support 3 and abuts against the front surface of the bracket 2, and the third return spring 62 includes at least one spring member disposed on the front surface of the bracket 2 and elastically abuts against the support 3. The third threaded pair 61 and the spring member are arranged parallel to each other, so that when the distance of the third threaded pair 61 is adjusted, a force is applied or reduced to the bracket 2 from the abutment position, causing the spring member on the side to compress or extend, thereby realizing the displacement of the entire bracket 2, including the lens mount 1, perpendicular to the plane (front-back direction) where the optical lens 11 is located.
[0040] It is understood that in other embodiments, the first direction, the second direction, and the third direction can be other directions besides up and down, left and right, and front and back, such as directions that form a certain angle with the vertical and horizontal directions, as long as they can achieve the supporting and fixing function of the mirror base 1 in the bracket 2 and the function of adjusting the position or direction of the mirror base 1.
[0041] The first threaded pair 41 and the second threaded pair 51 independently include a threaded shaft and a threaded sleeve, the threaded sleeve is connected to the bracket 2, and one end of the threaded shaft abuts against the mirror base 1; the third threaded pair 61 includes a threaded shaft and a threaded sleeve, the threaded sleeve is connected to the support base 3, and the threaded shaft abuts against the bracket 2.
[0042] In one embodiment, such as Figure 4 As shown, spring connectors 65 are respectively provided on both sides of the base 22 and the support 3. Each spring connector 65 has a hook at both ends. A first connecting post 63 is provided on each side of the base 22, and a second connecting post 64 is provided on each side of the support 3. The hooks at both ends of each spring connector are connected to the first connecting post 63 and the corresponding second connecting post 64, thereby elastically connecting the base 22 and the support 3 through the two spring connectors on both sides, improving the stability of the positional relationship between the support 3 and the base 22 of the bracket 2.
[0043] To further enhance the stability between the support base 3 and the bracket 2, at least one positioning pin 7 is provided between the support base 3 and the base 22. The number of positioning pins 7 is preferably two, three, or more. The positioning pin 7 is inserted into the positioning holes 71 at corresponding positions on the support base 3 and the bracket 2 to achieve positioning of the support base 3 and the bracket 2. In some embodiments, the positioning pin 7 includes a hollow cavity, and its outer diameter is capable of sliding at the front end of the positioning hole 71. A section of the third return spring 62 is disposed within the positioning hole 71 and extends into the cavity of the positioning pin 7, forming a positioning structure that can extend and retract along a plane perpendicular to the optical lens 11 (front-back direction). In some embodiments, at least one positioning pin 7 is fixed to the base 22 of the bracket 2.
[0044] In some embodiments, the optical frame 100 further includes a cover plate 8, which is detachably mounted to the support 2, for example, by bolts or screws, to protect the lens mount 1 and improve stability. Specifically, the cover plate 8 has a through hole 81 at the corresponding position of the optical lens 11 mounting position 10. The shape of the through hole 81 is adapted to the shape of the optical lens 11, and the size of the through hole 81 is not smaller than the size of the optical lens 11 so as not to affect the light path transmission of the optical lens 11.
[0045] In some embodiments, the base 22 has an elongated through hole along its height direction as a base bolt mounting hole 9 for fixing the optical frame 100 to the base. The elongated base bolt mounting hole 9 facilitates the movement of the base fixing bolt 91 within the mounting hole 9, allowing adjustment of the mounting position of the optical frame 100. The support base 3 also has an elongated support base fixing hole 31 along its height direction for mounting the support base fixing bolt 32.
[0046] Figure 5 A six-view drawing of an optical frame 100 provided in one embodiment is shown, clearly illustrating the positional relationship of the assembled components, demonstrating the feasibility of the embodiment of this application for practical industrial application.
[0047] The optical frame provided in this application embodiment can adjust the position of the optical frame in at least three directions. The adjustment method is simple and convenient, easy to operate, and can achieve different optical path outputs to meet the needs of different optical application scenarios.
