The present application is described in detail below with reference to the figures and alternative embodiments.

As shown in fig. 1 to 10, as an embodiment of the present application, an optical device 1 adjusting apparatus is disclosed. As shown in fig. 1 and 2 in particular, the adjusting device includes a fixed base 100, a floating mounting plate 200, and an adjusting assembly 300. The floating installation plate 200 is elastically connected to the fixing base 100. The adjusting assembly 300 is connected to the fixed base 100 and the floating installation plate 200, respectively, for adjusting the position of the floating installation plate 200 in the X-axis and Z-axis directions. The floating mounting plate 200 is used for mounting the optical device 1, and fig. 3 is a schematic diagram of mounting the optical device 1 on the floating mounting plate 200 of the adjusting device, which is not described herein again.

In a light path of a laser processing apparatus, there are usually many optical devices 1, such as an optical wave plate, a beam expander, a shaper, etc., and theoretically, the optical device 1 needs to be coaxial with a laser beam to achieve an optimal use effect, but in reality, the optical device 1 is difficult to maintain coaxial with the laser beam due to the influence of manufacturing precision, assembling precision, etc. It should be noted that the optical devices 1 are all mounted on mechanical parts, and the temperature change can cause the parts to have thermal expansion and cold contraction effects, so that the position of the optical device 1 changes; the change of humidity can make the mechanical parts not easy to keep stable in chemical property, and the change of chemical property is easy to occur to cause the change of external dimension. Therefore, the requirements of the laser processing equipment are in the environment with constant temperature and constant humidity, the experimental environment can keep constant temperature and constant humidity, but the constant temperature and constant humidity in the actual working condition are difficult to guarantee, and the change of the temperature and the humidity caused by water consumption, operation, processing and the like of various machines in the factory environment cannot be eliminated in time. Therefore, the temperature and humidity also affect the coaxiality of the optical device 1 and the laser beam.

The utility model provides an adjusting device, as required, through adjusting part 300 regulation mounting panel 200 that floats in the ascending position of X axle and Z axle side to make optical device 1 install after the mounting panel 200 that floats, can finely tune optical device 1 and laser beam's relative position, thereby make optical device 1 and laser beam coaxial center, improve the laser beam machining effect, simple structure, it is efficient, it is convenient to adjust the maintenance. It should be noted that the directions of the X-axis, the Y-axis, and the Z-axis described in the present application are determined by referring to the orthogonal spatial coordinate system indicated in fig. 1.

Further, as shown in fig. 1 and 2, the fourth screw 322 includes a first sub-screw 322a and a second sub-screw 322 b; the first sub-screw 322a and the second sub-screw 322b are arranged side by side in the X-axis direction. Because three points determine a plane, a plane is formed among the third screw 321, the first sub screw 322a and the second sub screw 322b, so as to ensure the stability of the floating installation plate 200, and the third screw 321, the first sub screw 322a and the second sub screw 322b can be contacted with the fixed base 100 at any time, so as to ensure the stability. If both sides are provided with 1 screw rod, only two pivot points are provided, and the floating installation plate 200 is unstable; if there are 2 or more than 2 third and

fourth screws

321 and 322 on both sides, there may be some cases where there is no contact between the screws and the fixing plate.
