[0018] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0019] See also Figure 1-Figure 5A cross roller moving platform structure includes a base 10, on which is disposed a moving platform 20 which moves forward and backward relative to the base 10, and on the left and right sides of the base 10, respectively, cross roller guide rails 30 are disposed, the cross roller guide rails 30 include a first guide rail 310, a second guide rail 320 and a retaining frame 330, the first guide rail 310 and the second guide rail 320 are arranged at intervals left and right, a retaining frame installation space 300 is formed between the first guide rail 310 and the second guide rail 320, the retaining frame 330 is arranged in the retaining frame installation space 300, the first guide rail 310 is fixedly arranged on the moving platform 20, the second guide rail 320 is arranged to move left and right relative to the base 10, and the base 10 is provided with an adjusting element for driving the second guide rail 320 to move relative to the base 10 to adjust the left and right width of the retaining frame installation space 300.

[0020] The utility model uses a second guide rail that can be moved and adjusted. After the moving platform is installed on the base, the adjusting element can be used to drive the second guide rail to adjust the left and right position, so as to change the distance between the first guide rail and the second guide rail, thereby changing the left and right width of the mounting space of the retaining frame, so that the first guide rail and the second guide rail fit the retaining frame to reduce the possibility of the moving platform shaking and improve the operation stability.

[0021] See also Figures 1 to 3 The base 10 is provided with a plurality of threaded holes 110, and the axial direction of the threaded hole 110 is consistent with the left-right movement direction of the second guide rail 320; the adjusting element is a bolt and is threadedly connected in the threaded hole 110, and one end of the adjusting element is in contact with the end surface of the second guide rail 320 facing away from the first guide rail 310.

[0022] As the adjusting element is tightened in the threaded hole 110, it pushes the second guide rail 320 to move toward the first guide rail 310. In this process, as the second guide rail 320 gradually moves toward the first guide rail 310, the left and right width of the mounting space of the holder gradually decreases. Conversely, as the adjusting element is loosened in the threaded hole 110, the left and right width of the mounting space of the holder gradually increases. By adjusting the spacing between the first guide rail and the second guide rail to change the fit between the first guide rail and the second guide rail and the holder 330, the moving stability of the moving stage is ensured.

[0023] Furthermore, the plurality of threaded holes 110 are arranged on the base 10 in a front-to-back arrangement.
