[0020] The following specific embodiments can further clearly understand the present patent, but they do not limit the present patent.
[0021] Embodiment 1: An optical image measuring instrument, comprising: a workbench 5 and a housing 1 located on the top of the workbench 5. A chute 6 is provided on the rear side surface of the housing 1 along the length direction. A threaded rod 2 is rotatably installed inside the chute 6. A moving block 3 located inside the chute 6 is threadedly connected to the threaded rod 2;

The sliding block threadedly connected to the threaded rod moves along the chute. The sliding block is fixedly connected to the sliding plate, thereby driving the sliding plate to move in the vertical direction;

A first limiting strip 8 is vertically arranged on the front side surface of the housing 1. The sliding plate 7 is provided with a limiting groove 9 for the first limiting strip 8 to be correspondingly embedded.
[0024] During the process of the sliding plate sleeved on the outer wall of the housing moving in the vertical direction, the cooperation between the first limiting strip on the front side surface of the housing and the limiting groove of the sliding plate can limit the left and right offsets of the sliding plate; the cooperation between the second limiting strips on the left and right side surfaces of the housing and the second limiting grooves of the sliding plate can limit the front and back offsets of the sliding plate, greatly improving the position accuracy of the sliding plate and avoiding the situation of the sliding plate tilting and offsetting.

[0027] A first motor 13 for driving the threaded rod 2 to rotate is provided on the top of the above-mentioned housing 1.
[0028] A second bearing 10 is provided between the above-mentioned threaded rod 2 and the inner wall of the above-mentioned chute 6.

[0030] Embodiment 2: An optical image measuring instrument, comprising: a workbench 5 and a housing 1 located on the top of the workbench 5. A chute 6 is provided on the rear side surface of the housing 1 along the length direction. A threaded rod 2 is rotatably installed inside the chute 6. A moving block 3 located inside the chute 6 is threadedly connected to the threaded rod 2;
[0031] The rotation of a threaded rod drives a sliding block to drive a sliding plate to move. During the vertical movement of the sliding plate, the cooperation between the first limiting strip and the limiting groove greatly improves the stability of the movement of the main lens, avoids the inclination of the main lens, improves the position accuracy of the main lens, and improves the measurement accuracy.
[0032] A sliding plate 7 equipped with a main lens 4 is sleeved on the outer wall of the circumference of the housing 1. The sliding plate 7 is fixedly connected to the moving block 3. A first limiting strip 8 is vertically arranged on the front surface of the housing 1, and the sliding plate 7 is provided with a limiting groove 9 for the corresponding embedding of the first limiting strip 8.
[0033] During the vertical movement of the sliding plate, the sliding plate is limited by the second limiting strip and the first limiting strip together, further improving the stability of the movement of the sliding plate, avoiding the situation that the main lens is offset due to the offset of the sliding plate, and greatly improving the measurement accuracy.
[0034] A second limiting strip 11 is arranged on both the left surface and the right surface of the housing 1, and the sliding plate 7 is provided with a second limiting groove 12 for the embedding of the second limiting strip 11.

[0039] The working principle is as follows:
[0040] During use, by controlling the start of the first motor, the output shaft of the first motor drives the threaded rod to rotate. The sliding block threadedly connected to the threaded rod moves along the sliding groove. The sliding block is fixedly connected to the sliding plate, thereby driving the sliding plate to move vertically.
[0041] During the vertical movement of the sliding plate sleeved on the outer wall of the housing, the cooperation between the first limiting strip on the front surface of the housing and the limiting groove of the sliding plate can limit the left and right offsets of the sliding plate; the cooperation between the second limiting strips on the left and right surfaces of the housing and the second limiting grooves of the sliding plate can limit the front and rear offsets of the sliding plate, greatly improving the position accuracy of the sliding plate and avoiding the situation of inclination and offset of the sliding plate.
[0042] When the above optical image measuring instrument is adopted, a threaded rod rotates to drive a sliding block to drive a sliding plate to move. During the vertical movement of the sliding plate, the cooperation between the first limiting strip and the limiting groove greatly improves the stability of the movement of the main lens, avoids the situation of the inclination of the main lens, improves the position accuracy of the main lens, and improves the measurement accuracy.
[0043] Furthermore, during the vertical movement of the sliding plate, the second limiting strip and the first limiting strip jointly limit the sliding plate, further improving the stability of the movement of the sliding plate, avoiding the situation of the deviation of the main lens caused by the deviation of the sliding plate, and greatly improving the measurement accuracy.
