This device is widely used in scientific research, industrial testing and quality detection fields, and the position or angle of the detection platform is accurately adjusted to meet the needs of different experiments or tests.

[0003] For example, the Chinese authorized patent "height adjusting device of detection platform of laser interferometer" with publication number CN212871087U includes a workbench, a plurality of third sleeves are fixedly connected to the lower side of the workbench, a second support column is slidably connected to the inner side of the third sleeve, a first sleeve is fixedly connected to the lower side of the workbench, a first support column is slidably connected to the inner side of the first sleeve, and an adjusting mechanism for adjusting the height of the workbench is arranged in the first sleeve.

[0004] Although the above-mentioned prior art can realize the height adjustment of the detection platform, with the continuous development of automation, higher requirements are put forward for the flexibility of the detection platform. The existing technology has poor adjustment freedom, which not only affects the detection accuracy, but also has great detection limitations, so it does not meet the existing needs. Therefore, we propose a detection platform precision adjusting device. UTILITY MODEL CONTENTS

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model features a height adjustment mechanism. By activating the first servo motor, its output shaft drives the stud to rotate. The friction between the external thread of the stud and the internal thread of the lifting column, combined with the guiding effect of the transmission cavity on the lifting column, allows the lifting column to drive the detection platform to adjust its height. Through the up-and-down movement of the lifting column, the height of the detection platform can be easily and precisely adjusted.

[0015] 2. This utility model features a rotating base. By activating the second servo motor at the upper end of the lifting column, the output shaft drives the rotating base to rotate, thereby adjusting the rotation angle of the testing platform. The tilt angle of the testing platform can be adjusted according to the actual testing conditions. Activating the third servo motor causes the output shaft to rotate the worm gear. The contact surface between the worm gear and the worm wheel forms a spiral friction transmission surface. The rotation of the worm gear drives the worm wheel to rotate, which in turn drives the rotating shaft to rotate. One end of the rotating shaft is fixed to the connecting frame, thus adjusting the tilt angle of the testing platform. On one hand, the self-locking property of the worm gear and worm wheel ensures the stability of the testing platform after tilt adjustment. On the other hand, in conjunction with the height adjustment mechanism, the height, rotation angle, and tilt angle of the testing platform can be precisely adjusted, allowing users to adjust the position of the testing platform according to actual testing conditions to meet different testing needs.
