As shown in fig. 1 and 2, a two-dimensional positioning device for an optical element is characterized by comprising a sliding component and a positioning component, wherein the sliding component comprises a first guide rail 11 and a second guide rail 21 which are cross-connected through a first slide block 12, and a second slide block 22 is arranged on the second guide rail 21. The first guide rail 11 and the second guide rail 21 are orthogonally arranged, the first slide block 12 drives the second guide rail 21 and the second slide block 22 on the second guide rail 21 to transversely reciprocate on the first guide rail 11, and the second slide block 22 longitudinally reciprocates on the second guide rail 21.
The positioning component comprises a fixed block 3 which is fixed at one end of the first guide rail 11 and can indicate an angle, and the fixed block 3 and the second sliding block 22 are movably connected through a connecting component 4. The connection mode is as follows, be equipped with first boss 71 and second boss 72 on fixed block 3 and the second slider 22 respectively, first boss 71 and second boss 72 are gone up and are cup jointed first ring 51 and second ring 52 respectively in the activity, be equipped with on the second ring 52 and be used for cup jointing the connecting piece 4 connect the hole 521, second ring 52 central axis with connect hole 521 central axis perpendicular setting, connecting piece 4 one end is connected first ring 51, the other end passes connect hole 521, connect hole 521 with connecting piece 4 clearance fit. The fixed block 3 and the second sliding block 22 are on the same horizontal plane. When the first slider 12 and the second slider 22 move, the connecting member 4 moves in a certain range with the center of the first boss 71, and the fixing block 3 and the second slider 22 are on the same horizontal plane due to the clearance fit between the connecting hole 521 and the connecting member 4, so that the components do not interfere when the first slider 12 and the first slider 22 move.
The connecting part 4 is provided with a scale for indicating the length. The connecting part 4 is of a linear structure, and the length of the connecting part is larger than the maximum distance between the fixed block 3 and the second sliding block 22. Specifically, the connecting component adopts a connecting rod. The linear structure facilitates reading the distance between the fixed block 3 and the second slider 22. The fixed block 3 is provided with a scale for indicating the angle. The scale on the fixed block 3 can read the angle between the fixed block 3 and the second slider 22. The position relationship of the two optical elements can be determined according to the angle and the distance between the fixed block 3 and the second sliding block 22, so that the optical elements can be positioned quickly and accurately.

The working principle of the invention is as follows:
in use, the present invention first secures the two optical elements to the first boss 71 and the second boss 72, respectively, by means of a clamp.
Since the first ring 51 and the second ring 52 are movably sleeved on the first boss 71 and the second boss 72 respectively, i.e. the first ring 51 can rotate around the first boss 71, and the second ring 52 can rotate around the second boss 72; one end of the connecting component 4 is connected to the first circular ring 51, the other end passes through the connecting hole 521 on the second circular ring 52, and since the central axis of the second circular ring 52 is perpendicular to the central axis of the connecting hole 521, the fixed block 3 and the second slider 22 are on the same horizontal plane, so that the connecting component 4 is in a horizontal state, when the first slider 12 and the second slider 22 move on the first guide rail 11 and the second guide rail 21 respectively, the connecting component 4 rotates around the first boss 71, the second circular ring 52 drives the connecting hole 521 to rotate around the second boss 72, so that the optical elements on the first boss 71 and the second boss 72 are continuously positioned, and all the components do not interfere with each other.
Because the fixed block 3 is provided with the scale for indicating the angle, the connecting part 4 is provided with the scale for indicating the length, when two optical elements are positioned well, the angle and the length at the moment are read, and the optical elements can be positioned rapidly and accurately only by adjusting the angle and the scale to the corresponding angle and the scale when the optical elements are operated next time.
