[0030] As shown in Figures 1-7 The utility model provides a kind of adjustable five-axis object table for optical experiment, to solve the problem of insufficient adjustment function of traditional object table in optical experiment. The following is a detailed description of the specific embodiments of the present application.
[0031] Firstly, the optical experiment adjustment object table of the present application is sequentially stacked from bottom to top with moving base 1, link table 2, middle table 3, adjustment table 4 and object disc 5. This stacked arrangement not only ensures the stability of the object table, but also enables the various parts to cooperate with each other to achieve multiple adjustment functions.
[0032] Between the middle table 3 and the adjustment table 4, the present application specially provides a first inclination adjustment mechanism 7 and a second inclination adjustment mechanism 8 for adjusting the inclination direction and angle of the adjustment table 4. The two inclination adjustment mechanisms have the same structure and are vertically symmetrical arranged on the adjacent sides of the middle table 3. By adjusting these two mechanisms, the user can easily change the inclination direction and angle of the adjustment table 4, thus meeting the fine adjustment requirements of the inclination angle of the object table in the experiment.
[0033] In order to further enhance the functionality of the adjustment table 4, the present application further provides a rotatable spin ball 6 between the axial line positions of the middle table 3 and the adjustment table 4. The upper surface of the middle table 3 is recessed with a lower spin groove 31, the lower surface of the adjustment table 4 is recessed with an upper spin groove 44, and the upper and lower sides of the spin ball 6 are respectively movably accommodated in these spin grooves. In this way, the adjustment table 4 can be tilted around the spin ball 6 to adjust the angle of the object table, while also serving as a support and stabilizer.
[0034] In the first inclination adjusting mechanism 7, the application adopts a threaded adjustable connection mode. Specifically, the first adjusting member 71 is threadedly connected to the middle base 3, and the end thereof is used to push the adjusting base 4. In order to reduce the friction, the end of the first adjusting member 71 is further rotationally connected to the ball 72, and the top end of the ball 72 abuts against the bottom end of the adjusting base 4. In this way, when the user rotates the first adjusting member 71, the ball 72 can roll and push the adjusting base 4 to incline.
[0035] In order to maintain the abutting state between the adjusting base 4 and the ends of the first adjusting member 71 and the second adjusting member, the application further tensionally arranges the tension spring 9 between the middle base 3 and the adjusting base 4. The tension of the tension spring 9 causes the adjusting base 4 to always be subjected to a certain pushing force, thereby ensuring the stability of the adjusting base 4 during the inclination adjustment.
[0036] On the adjusting base 4, the application further arranges the threaded convex column 41 and the positioning bolt 43. The threaded convex column 41 is vertically fixed at the axial center position of the upper surface of the adjusting base 4, and the axial center position of the lower surface of the object carrier 5 is correspondingly arranged with the threaded hole 51. Through the cooperation of the threaded hole 51 and the threaded convex column 41, the object carrier 5 can be rotationally and adjustably connected with the adjusting base 4. When the user needs to fix the object carrier 5, the positioning bolt 43 can be rotated to abut against the side surface of the object carrier 5.
[0037] In addition, in order to limit the movement range of the object carrier 5 during the adjustment, the application further forms the limiting convex ring 42 around the threaded convex column 41 on the upper surface of the adjusting base 4. Correspondingly, the lower surface of the object carrier 5 is correspondingly formed with the limiting concave ring 52 which is embedded with the limiting convex ring 42. In this way, when the object carrier 5 rotates, the limiting convex ring 42 and the limiting concave ring 52 can be embedded with each other, thereby limiting the movement of the object carrier 5 and making the object carrier 5 more stable.
[0038] The moving base 1 of the application can also be adjusted and moved in the first direction and the second direction. The structure of the moving base 1 can refer to the structure of the moving base in the patent CN217561800U, and the specific structure will not be described in detail. This design enables the user to move the object carrier to a suitable position according to the experimental requirements, thereby further improving the flexibility and convenience of the experiment.
[0039] The optical experiment adjusting object table has multiple adjusting functions, stable connecting modes and wide moving range, and can meet diversified requirements in complex experiments.
[0040] The above is only the preferred embodiment of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement, improvement and the like made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
[0041] In addition, it should be understood that, although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the specification is described in this way only for clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be properly combined to form other embodiments that those skilled in the art can understand.
