It is difficult to ensure the accuracy of angle adjustment by manual adjustment, and the adjustment angle is often too small or too large due to inappropriate force, which seriously affects the adjustment speed.

[0057] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0058] Example

[0059] A specific embodiment of the utility model is as follows Figure 1 , Figure 2 , Figure 8 and Fig. 9 As shown, an angle adjustment structure 3 of an optical element fixing seat is disclosed, including a fixing part 100 and an adjusting part 200; the adjusting part 200 includes an adjusting member support seat 210 and an adjusting member 220; the fixing part 100 includes a fixing block 110 and a first position adjustment component 120; the first position adjustment component 120 includes a first ball joint unit and a second ball joint unit; the fixing block 110, the first ball joint unit, the second ball joint unit and the adjusting member support seat 210 are connected in sequence; the fixing block 110 is connected to the optical element fixing seat support frame 1 or the base plate 2 of the laser; the adjusting member 220 penetrates the adjusting member support seat 210 and then pushes the optical element fixing seat support frame 1 to move, so as to adjust the angle between the optical axis of the optical element on the optical element fixing seat support frame 1 and the optical path of the laser.

[0060] In this embodiment, after the fixing part 100 is connected to the base plate 2 in the laser or the optical element fixing seat support frame 1, it provides stable support for the adjustment member support seat 210. When the adjustment member 220 pushes the optical element fixing seat support frame 1 to move, the adjustment member support seat 210 is ensured not to move, thereby improving the adjustment accuracy.

[0061] In this embodiment, an adjustment member 220 with different pitches is selected as needed, and the adjustment member 220 is rotated to control the movement distance of the optical element fixing seat support frame 1, thereby controlling the adjustment of the angle between the optical axis of the optical element mounted on the optical element fixing seat support frame 1 and the laser optical path. Compared with the existing manual adjustment, not only the adjustment process is controllable and the adjustment accuracy is improved, but also the adjustment efficiency can be significantly improved.

[0062] In this embodiment, after the adjustment is completed, the optical element fixing seat and the optical element, and the optical element fixing seat support frame 1 and the bottom plate 2 are tightened by screws to move the adjustment member 220 away from the optical element fixing seat support frame 1. Because the connections between the various components in the fixing part 100 and the adjustment part 200 are rigid connections, and no elastic connection is involved, the structure of the utility model does not contact the optical element fixing seat support frame 1 after the adjustment is completed, so there will be no problem of adjustment angle change due to elastic deformation during and after the adjustment process, which not only facilitates adjustment and improves adjustment efficiency, but also can maintain the angle between the optical axis of the optical element and the laser optical path unchanged for a long time, ensuring the stability of laser light output.

[0063] In this embodiment, the adjusting member 220 is preferably a screw or a jackscrew.

[0064] Furthermore, in order to achieve the adjustment of the optical element fixing seat support frame 1 in multiple directions, the fixing part 100 further includes a first position adjustment component 120, such as Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the first position adjustment assembly 120 includes a first ball seat 121, a first ball head rod 122, an intermediate connecting member 123, a second ball head rod 124, and a second ball seat 125 connected in sequence; the second ball seat 125 is connected to the adjustment member support seat 210. The first ball seat 121 is connected to the fixing block 110; the second ball seat 125 is connected to the adjustment member support seat 210.

[0065] In this embodiment, a first ball joint unit is formed by connecting the first ball seat 121 and the ball head on the first ball head rod 122 , so as to adjust the direction of the shaft on the first ball head rod 122 .

[0066] In this embodiment, the first ball head rod 122 is connected to the second ball head rod 124 through the intermediate connecting member 123, and the central axis of the first ball head rod 122 is colinear with the central axis of the second ball head rod 124, and the second ball head rod 124 moves synchronously with the first ball head rod 122. At the same time, because the first ball head rod 122 and the second ball head rod 124 are respectively screwed to the intermediate connecting member 123, the adjustment of the distance between the first ball seat 121 and the second ball seat 125 is achieved, so that when the fixing block 110 is fixed, the adjustment member support seat 210 has a larger use range.

[0067] In this embodiment, the second ball joint unit is formed by connecting the ball head on the second ball head rod 124 with the second ball seat 125 to achieve the adjustment of the direction of the second ball seat 125. Because the second ball seat 125 is connected to the adjustment member support seat 210, the direction of the adjustment member support seat 210 can be adjusted.

[0068] In this embodiment, the first ball seat 121 is connected to the fixing block 110. The second ball seat 125 is connected to the adjusting member support seat 210. Figure 4 shown.

[0070] Furthermore, the moving member 132 is connected to the adjusting member support seat 210, such as Figure 5 As shown, by adjusting the distance between the moving member 132 and the fixed block 110 , the distance between the adjusting member support seat 210 and the fixed block 110 is adjusted.

[0071] Furthermore, the moving member 132 is connected to the adjusting member support seat 210 through the first position adjusting assembly 120, such as Figure 2 and Figure 3 As shown in more detail, the movable member 132 is connected to the first ball seat 121, and the second ball seat 125 is connected to the adjusting member support seat 210. By adjusting the distance between the movable member 132 and the fixed block 110, the first ball seat 121 is driven to move, thereby completing the adjustment of the distance between the adjusting member support seat 210 and the fixed block 110.

[0073] Furthermore, considering the position limitation of the moving member 132 on the connecting rod 131, the first position adjustment assembly 120 further includes a position limiting rod 126, such as Figure 6 As shown, the moving member 132 also includes a limiting screw hole 1322. Figure 7 As shown, one end of the limiting rod 126 is connected to the first ball seat 121 or the adjusting member support seat 210 , and the other end passes through the limiting screw hole 1322 and abuts against the connecting rod 131 to complete the compression and limiting of the connecting rod 131 .

[0074] Further, considering the fixation of the fixing block 110, the angle adjustment structure 3 of the optical element fixing seat in this embodiment further includes a threaded fixing hole group, and the threaded fixing hole group includes a first hole 410 and a second hole, such as Figure 1 , Figure 3 and Figure 8 As shown; the first hole 410 is arranged on the fixing block 110; the second hole is arranged on the base plate 2 of the laser and / or the optical element fixing seat support frame 1.
