DETAILED DESCRIPTION

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] Example 1

[0025] like Figs. 1 to 5 As shown, this embodiment provides a high-precision height-adjustable rack for a stone carving machine, including a rack 1 and a base 2. The base 2 includes a low mounting surface 3 and a high mounting surface 4. The low mounting surface 3 is used to mount a guide rail 15, and the high mounting surface 4 is used to mount the rack 1. A sliding surface 5 is provided between the low mounting surface 3 and the high mounting surface 4. By setting the sliding surface 5, a gap is left between the low mounting surface 3 and the high mounting surface 4 to create space for the slide block on the guide rail 15 to slide.

[0026] The distance between the lower mounting surface 3 and the sliding surface 5 is 2-3mm. By setting the lower mounting surface 3 to be lower than the sliding surface 5, a limiting step is formed between the sliding surface 5 and the lower mounting surface 3. When the guide rail 15 is installed, the limiting step plays a role in limiting and calibrating the guide rail 15, thereby improving the installation efficiency of the guide rail 15.

[0027] An installation step 6 is provided on the high mounting surface 4. The height of the installation step 6 is 2-3mm. The installation step 6 serves to limit and calibrate the rack 1, thereby improving the installation efficiency of the rack 1.

[0028] The width ratio of the low mounting surface 3 to the sliding surface 5 is 11:9.

[0029] The distance by which the rack 1 extends outward from the right side wall of the base 2 is D, where D = 2mm + L, and L is the tooth height of the rack 1.

[0030] The height difference H between the low mounting surface 3 and the high mounting surface 4 is 20mm.
