[0026] Please see Figure 1-Figure 4 In this embodiment of the invention, an automatic adjustable sample lifting platform for a nanoindentation instrument includes a base housing 1 and several sample stages 17.

The side wall of the first internal thread rotating cylinder 6 is provided with a first driving component for driving the first internal thread rotating cylinder 6 to rotate.

[0028] The first drive assembly includes a gear ring 5, which is mounted on the side wall of the first internal thread rotating cylinder 6. A first motor 8 is vertically mounted at the bottom of the base housing 1 near the first internal thread rotating cylinder 6. A first rotating rod 10 is vertically mounted at the output end of the first motor 8. A gear 11 that works with the gear ring 5 is mounted at the end of the first rotating rod 10 away from the first motor 8. The gear ring 5 and the gear 11 mesh with each other.

[0029] When in use, the first motor 8 is started. The output end of the first motor 8 drives the first rotating rod 10 to rotate. The first rotating rod 10 drives the gear 11 to rotate. The gear 11 drives the gear ring 5 to rotate. The gear ring 5 drives the first internal thread rotating cylinder 6 to rotate. Under the action of the thread, the first internal thread rotating cylinder 6 drives the first external thread moving block 24 to move up and down. The first external thread moving block 24 drives the square moving rod 23 to move along the inner wall of the first limit frame 22. The square moving rod 23 drives the lifting plate 21 to move up and down. The lifting plate 21 drives the sample stage 17 to move up and down.

[0030] The fixing mechanism includes a square clamping rod 19, which is horizontally slidably connected to the inner wall of the second limiting frame 18. The end of the square clamping rod 19 away from the test sample stage placement frame 3 passes through the second limiting frame 18 and is equipped with a second external thread moving block 20.

A bevel gear 13 that cooperates with the annular bevel gear 14 is mounted at the end of the second rotating rod 12 away from the second motor 9. The bevel gear 13 and the annular bevel gear 14 mesh with each other.

[0032] When in use, the second motor 9 is started. The output end of the second motor 9 drives the second rotating rod 12 to rotate. The second rotating rod 12 drives the bevel gear 13 to rotate. The bevel gear 13 drives the ring bevel gear 14 to rotate. The ring bevel gear 14 drives the second internal thread rotating cylinder 16 to rotate. Under the action of the thread, the second internal thread rotating cylinder 16 drives the second external thread moving block 20 to move. The second external thread moving block 20 drives the square clamping rod 19 to move. The square clamping rod 19 moves along the inner wall of the second limiting frame 18, so that the square clamping rod 19 fixes or releases the sample stage 17 inside the test sample stage placement frame 3.

[0033] The working principle of an automatic sample lifting stage for a nanoindentation instrument:

[0034] When raising or lowering the sample stage 17 inside the sample stage placement frame 3, the user sends a command signal to the remote controller 4 via a computer. The remote controller 4 first controls the second motor 9 on the sample stage placement frame 3 to start. The output end of the second motor 9 drives the second rotating rod 12 to rotate. The second rotating rod 12 drives the bevel gear 13 to rotate. The bevel gear 13 drives the ring bevel gear 14 to rotate. The ring bevel gear 14 drives the second internal thread rotating cylinder 16 to rotate. Under the action of the thread, the second internal thread rotating cylinder 16 drives the second external thread moving block 20 to move. The second external thread moving block 20 drives the square clamping rod 19 away from the sample stage placement frame 3, so that the square clamping rod 19 releases the sample stage 17 inside the sample stage placement frame 3.

[0035] Then, the first motor 8 on the corresponding sample stage placement frame 3 is started. The output end of the first motor 8 drives the first rotating rod 10 to rotate. The first rotating rod 10 drives the gear 11 to rotate. The gear 11 drives the gear ring 5 to rotate. The gear ring 5 drives the first internal thread rotating cylinder 6 to rotate. Under the action of the thread, the first internal thread rotating cylinder 6 drives the first external thread moving block 24 to move up and down. The first external thread moving block 24 drives the square moving rod 23 to move along the inner wall of the first limiting frame 22. The square moving rod 23 drives the lifting plate 21 to move up and down. The lifting plate 21 drives the sample stage 17 to move up and down.

[0036] After the sample stage 17 is raised and lowered, the second motor 9 on the corresponding test sample stage placement frame 3 is started. The output end of the second motor 9 drives the second rotating rod 12 to rotate. The second rotating rod 12 drives the bevel gear 13 to rotate. The bevel gear 13 drives the ring bevel gear 14 to rotate. The ring bevel gear 14 drives the second internal thread rotating cylinder 16 to rotate. Under the action of the thread, the second internal thread rotating cylinder 16 drives the second external thread moving block 20 to move. The second external thread moving block 20 drives the square clamping rod 19 to approach the test sample stage placement frame 3, so that the square clamping rod 19 presses and fixes the sample stage 17 inside the test sample stage placement frame 3.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
