[0036] The present utility model embodiment provides a laser calibration fixture for calibrating the light beam emitted by the optical component 100; Figure 1 , the laser calibration fixture comprises:

[0037] Hollow platform 1;

[0038] The verticality correction assembly 2 includes a slide 21 and a first gauge block 22, wherein: the slide 21 is slidably mounted on the hollow platform 1 along the vertical direction; the first gauge block 22 is fixed on the slide 21;

[0039] The round hole calibration sheet 3 is fixedly mounted on the hollow platform 1 .

[0040] In the above structure, the optical component 100 includes a laser for emitting laser light; the optical component 100 is installed on a movable shaft (not shown in the figure), and when in use, the movable shaft can drive the optical component 100 to move in space.

[0041] The use process of the laser calibration fixture is as follows:

[0042] Correct the verticality of the light beam: align the first gauge block 22 on the slide 21 with the light-emitting end of the optical component 100, move the slide 21 up and down, and then drive the first gauge block 22 to move up and down; during the up and down movement of the first gauge block 22, if the result of the laser measurement changes, it means that the laser is not perpendicular to the horizontal plane; adjust the optical component 100 until the verticality of the laser and the horizontal plane meets the requirement;

[0043] Correct the parallelism of the installation of the optical component 100 and the moving axis: move the optical component 100 or the moving hollow platform 1 so that the light-emitting end of the optical component 100 is aligned with the circular hole calibration plate 3; move the moving axis back and forth along the axial direction of the moving axis (in an ideal state, the axial direction of the moving axis is the vertical direction), and drive the optical component 100 to move back and forth along the axial direction of the moving axis; during the axial movement of the moving axis and the optical component 100, if the light spot is offset, it means that the moving axis and the optical component 100 are not installed in parallel; adjust the optical component 100 and / or the moving axis until the parallelism of the installation of the optical component 100 and the moving axis meets the requirements.

[0044] Through the above process, the laser calibration fixture provided by the present application can calibrate the optical component 100, thereby improving the accuracy of the optical path. The fixture has the advantages of simple operation, low cost and wide application range, which not only reduces the technical level requirements for operators, but also is suitable for laser calibration inside and outside the factory, and has high versatility.

[0045] Reference Figure 2 A through hole 11 is provided in the middle of the hollow platform 1, and a slide seat 21 is suspended in the inner ring of the through hole 11. When the fixture is in use, the slide seat 21 can pass through the through hole 11 up and down.

[0046] When the fixture is in use, the light-emitting end of the laser can be located at the upper and / or lower end of the hollow platform 1, and the light beams emitted from the upper and lower ends of the hollow platform 1 can pass through the through hole 11, so that the fixture can meet the detection requirements under various working conditions.

[0047] On the basis of the above structure, the inner circumference of the through hole 11 is provided with a step surface 12 extending inwardly. The step surface 12 can limit the position of the hollow platform 1, thereby improving the installation accuracy of the hollow platform 1.

[0048] Furthermore, the laser calibration fixture further includes a position adjustment mechanism for driving the hollow platform 1 to move;

[0049] The hollow platform 1 is provided with a mounting hole 13 for connecting the position adjustment mechanism.

[0050] In the above structure, the position adjustment mechanism (not shown in the figure) is used to drive the hollow platform 1 to move in a plane or in space. The position adjustment mechanism can be an electric slide rail, which can be set according to actual conditions and is not limited here.

[0051] In other embodiments, the position adjustment mechanism may not be provided, and the position of the hollow platform 1 may be adjusted manually.

[0052] Continue to refer to Figure 2 The verticality correction assembly 2 further includes a driving structure 23, which is mounted on the hollow platform 1, and whose power output end is connected to the slide 21. The driving structure 23 is used to drive the slide 21 and the first gauge block 22 on the slide 21 to reciprocate in the vertical direction to correct the verticality of the light beam and the horizontal plane.

[0053] In this embodiment, the driving structure 23 includes a driving motor. In other embodiments, the driving motor can also be replaced by a driving source such as a cylinder.

[0054] Furthermore, the verticality correction assembly 2 further includes a displacement meter 24, which is used to detect the displacement of the slide 21. In this embodiment, the displacement meter 24 has a display screen; when the slide 21 moves in the vertical direction, the displacement meter 24 can detect and display the displacement of the slide 21 in real time, thereby providing data support for the adjustment of the optical assembly 100, which is convenient for the operator to perform adjustment operations.

[0055] Continue to refer to Figure 2 The round hole verification sheet 3 is detachably mounted on the hollow platform 1 by fasteners such as screws, so as to facilitate the replacement of the round hole verification sheet 3.

[0056] Reference Figure 3 The laser calibration fixture further comprises a plurality of gauge block groups 4, each gauge block group 4 comprising a plurality of second gauge blocks 41 fixedly mounted on the hollow platform 1. Based on the above structure, each gauge block group 4 comprises a plurality of second gauge blocks 41 distributed side by side and / or vertically.

[0057] In this embodiment, a plurality of gauge block groups 4 are arranged around the periphery of the through hole 11 ; each gauge block group 4 includes two second gauge blocks 41 arranged side by side, and a second gauge block 41 perpendicular to the two second gauge blocks 41 arranged side by side.

[0058] When in use, the hollow platform 1 is moved to the preset installation area manually or through a position adjustment mechanism; the light-emitting end of the optical component 100 is aligned with each second gauge block 41, and the position data of each second gauge block 41 is measured to see whether it is consistent with the preset data; if not, the position of the hollow platform 1 is adjusted manually or through a position adjustment mechanism until the position data actually measured by the second gauge block 41 is consistent with the preset data, thereby confirming that the correlation between the optical component 100 and the hollow platform 1 is within the required accuracy range.

[0059] During the calibration process, the laser calibration fixture provided in the present application can repeatedly confirm whether the adjusted optical component 100 meets the design accuracy requirements through multiple groups of gauge blocks 4.

[0060] Exemplarily, after the optical component 100 has been used for a period of time, the optical component 100 is moved to measure the position data of each second gauge block 41; since the hollow platform 1 has been adjusted to the preset installation area and will not move again, if the measured position data of the second gauge block 41 is inconsistent with the preset data, it means that the optical path is offset and needs to be re-calibrated.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
