[0015] See also Figure 1-Figure 3 Description: A dual-probe four-laser beam focus positioning device comprises a positioning plate 7, a first laser head 1 and a second laser head 2;

[0017] The angle between the No. 1 laser beam 3 of the No. 1 laser head and the No. 2 laser beam 4 of the No. 1 laser head is determined by the original manufacturer when the No. 1 laser head 1 leaves the factory. The angle between the No. 3 laser beam 5 of the No. 2 laser head and the No. 4 laser beam 6 of the No. 2 laser head is determined by the original manufacturer when the No. 2 laser head 2 leaves the factory.

[0018] Furthermore, the thickness of the positioning plate 7 is more than 8 mm. A thicker positioning plate is used to ensure that the processing does not deform, wherein the No. 1 laser through hole 8 and the No. 2 laser through hole 9 are processed according to the angle between the two laser beams of the No. 1 laser head 1, and the No. 3 laser through hole 10 and the No. 4 laser through hole 11 are processed according to the angle between the two laser beams of the No. 2 laser head 2. The relative positions of the No. 1 laser through hole 8, the No. 2 laser through hole 9, the No. 3 laser through hole 10 and the No. 4 laser through hole 11 are determined according to the distance of the positioning plate 7 relative to the four laser beam focal points 12. In this way, the thickness of the positioning plate 7 is a plate material of more than 8 mm, and four laser through holes are processed on the positioning plate 7 at a certain angle, and the structure is as follows: Figure 1 As shown, by adjusting the probe position of the dual-probe four-laser beam measuring device, the rays emitted by it pass through four laser through holes as shown in Figure 3 As shown, the relative position of the laser focus can be determined accurately.

[0023] 3. According to the measurement requirements, the distance between the focus positioning plate 7 and the measurement focus 12 is predetermined.
