[0002] The sliding door of a CNC machine tool plays a protective role during the processing of the CNC machine tool. In the existing technology, when the sliding door is installed, the upper roller on the sliding door is usually clamped by the guide groove on the outer shell of the CNC machine tool, so that the upper roller rolls along the guide groove with the sliding door to guide the sliding door. However, due to manufacturing errors, a large gap needs to be left, which makes the sliding door easy to shake when moving. In addition, the sliding door has no upper and lower support structures, and the high and low positions of the sliding door cannot be guaranteed during operation, which is easy to interfere with other parts. In addition, the support base in the outer shell of the CNC machine tool that supports and guides the lower roller of the sliding door adopts a sheet metal bending structure, but the bending strength of the sheet metal is limited, and it cannot provide stable support for heavy sliding doors. Moreover, after the sheet metal is bent, it is easy to cause the overall bending of the support base. When the sliding door is running, part of the position is too low, which will interfere with the bottom and is difficult to correct. For this reason, a CNC machine tool sliding door roller structure that improves the movement stability of the sliding door is proposed. Summary of the invention
