[0032] Embodiment
[0033] This embodiment provides a multi-group laser coplanarity adjustment device, including: a rotary mounting base 11, a pitch mounting base 12, a pitch fixing base 13, and a front-back mounting base 15.
[0034] Specifically, referring to Figure 1 , on both sides of a bottom bracket 18, a front-back mounting base 15 is fixedly installed respectively. The front-back mounting base 15 is set in an inverted L-shaped structure, and a pitch fixing base 13 is connected between the tops of the two front-back mounting bases 15 by bolts.
[0035] Preferably, in a multi-group laser coplanarity adjustment device of this embodiment, a horizontal auxiliary adjustment component 16 is further provided between the two front-back mounting bases 15 and the pitch fixing base 13 respectively. The horizontal auxiliary adjustment component 16 includes a third stop block 161 fixedly connected to the side wall of the front-back mounting base 15. The third stop block 161 is set in an L shape, and its bottom plate is fixedly connected to the side wall of the front-back mounting base 15 by bolts. A gap is provided between the inner side wall of the vertical part of the third stop block 161 and the side wall of the pitch fixing base 13 for adjusting the position of the pitch fixing base 13 in the width direction.
[0036] At least one threaded through hole is provided on the vertical part of the third stop block 161, and a fourth bolt 162 is screwed thereon. By rotating the fourth bolts 162 on both sides of the pitch fixing base 13, the end of the fourth bolt 162 abuts against the side wall of the pitch fixing base 13 for adjusting and locking the position of the pitch fixing base 13 in the width direction.
[0037] Preferably, in a multi-group laser coplanarity adjustment device of this embodiment, a limiting block 17 is further provided between the ends of the front-back mounting base 15 and the pitch fixing base 13. The limiting block 17 is fixedly connected to the front-back mounting base 15, and a plurality of limiting blocks 17 respectively abut against both ends of the pitch fixing base 13 for positioning and locking the pitch fixing base 13 in the length direction.
[0038] Preferably, in a multi-group laser coplanarity adjustment device according to this embodiment, a plurality of oblong holes are further provided on the front and rear mounting seats 15, and locking bolts are arranged in the oblong holes and screwed onto the pitching fixing seat 13 for locking and fixing the front and rear mounting seats 15 and the pitching fixing seat 13.
[0039] Preferably, in a multi-group laser coplanarity adjustment device according to this embodiment, an arc-shaped groove is provided on the upper surface of the pitching fixing seat 13 along the length direction, and an arc-shaped guide rail matching (with the same radian) the arc-shaped groove is provided at the bottom of the pitching mounting seat 12. The thickness of the arc-shaped guide rail is greater than the depth of the arc-shaped groove, so that there is a gap between the bottom plane of the pitching mounting seat 12 on both sides of the arc-shaped guide rail and the upper surface plane of the pitching fixing seat 13. The size of the gap is set according to the deflection requirement, so that after the arc-shaped guide rail at the bottom of the pitching mounting seat 12 is embedded in the arc-shaped groove, the pitching mounting seat 12 can rotate around the axis direction of the arc-shaped groove to adjust the inclination angle of the pitching mounting seat 12.
[0040] Preferably, in a multi-group laser coplanarity adjustment device according to this embodiment, a plurality of through holes in the thickness direction are further provided at the corners of the pitching mounting seat 12. The inner diameter of the through hole is larger than the outer diameter of the thread of the second bolt and smaller than the outer diameter of the nut of the second bolt. The second bolt 121 is movably inserted into the through hole. The nut of the second bolt 121 abuts against the upper surface of the pitching mounting seat 12, and the lower end of the second bolt 121 is screwed into the threaded hole on the pitching fixing seat 13. During actual work, by rotating the second bolt 121, the inclination angle of the pitching mounting seat 12 relative to the pitching fixing seat 13 is adjusted and locked.
[0041] Preferably, in a multi-group laser coplanarity adjustment device according to this embodiment, a rotating shaft connection structure is provided at the central axis position between the rotating mounting seat 11 and the pitching mounting seat 12. The rotating mounting seat 11 is rotatably connected to the pitching mounting seat 12. Countersunk oblong holes are provided at the corners of the rotating mounting seat 11, and first bolts 111 are arranged in the countersunk oblong holes and connected to the corresponding threaded holes on the pitching mounting seat 12 for locking the rotating mounting seat 11 and the pitching mounting seat 12.
[0042] Preferably, in a multi-group laser coplanarity adjustment device according to this embodiment, two groups of rotation auxiliary adjustment components 14 are further provided between the rotating mounting seat 11 and the pitching mounting seat 12. The length of the rotating mounting seat 11 is smaller than that of the pitching mounting seat 12, and the two groups of rotation auxiliary adjustment components 14 are respectively arranged at both ends in the length direction of the rotating mounting seat 11.
[0043] Preferably, in a multi-group laser coplanar adjustment device according to this embodiment, the rotation auxiliary adjustment assembly 14 includes a first stop block 141 fixedly connected to the side wall of the rotation mounting base 11 and a second stop block 142 fixedly connected to the side wall of the pitching mounting base 12. The stop surfaces of the first stop block 141 and the second stop block 142 are arranged opposite to each other. A third bolt 143 is screwed on the second stop block 142. During actual operation, loosen all the first bolts 111, rotate the two third bolts 143 so that their ends abut against the first stop block 141 to adjust and lock the rotation position of the rotation mounting base 11.
[0044] Its working process is as follows: Install the 3 laser scanning modules 19 on 3 adjustment devices respectively, and then, taking the middle component as a reference, achieve laser coplanarity by adjusting the adjustment devices on both sides.
[0045] Specifically, first, visually inspect the middle component and adjust the component to a horizontal, centered, and parallel position with the bottom bracket as a reference. Then install one side component so that the two components work simultaneously, and observe the coincidence of the laser lines at near and far distances.
[0046] Step 1: If it is found that the two lasers cross, it is necessary to adjust the rotation mounting base 11 through the rotation auxiliary adjustment assembly 14 to rotate the rotation mounting base 11, thereby driving the rotation of the laser scanning module 19. During the adjustment rotation process, it is necessary to check the situation of the two laser lines and adjust them to be parallel. Then, it is necessary to lock the rotation mounting base 11 with the 4 first bolts around it;
[0047] Step 2: After completing Step 1, it is necessary to observe the distance situation of the two laser lines at near and far distances. If one of the following two situations is found, (1. The distances of the two laser lines at near and far distances are different; 2. The offsets of the laser lines at near and far distances are not on the same side), it is necessary to adjust the pitching angle of the component by adjusting the pitching mounting base 12 and the pitching fixing base 13 so that the offsets of the two laser lines at near and far distances are on the same side and the distances are the same. Then lock the pitching angle adjustment mechanism with 4 second bolts;
[0048] Step 3: Finally, adjust the horizontal movement of the pitching fixing base 13 by adjusting the horizontal auxiliary adjustment assembly 16 to make the two laser lines coincide. Then lock the front and rear adjustment structure with 4 bolts at the bottom. After adjusting the above 3 steps, the coplanarity of the two laser lines can be completed, and the coplanarity of multiple groups of laser lines can be achieved through the above steps.
[0049] Inspired by the ideal embodiments based on the present application described above, through the above description, relevant staff can fully make various changes and modifications without departing from the technical idea of this application. The technical scope of this application is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
