Abstract
Description
Technical Field
[0001] The utility model relates to a cross slide, in particular to a machine tool cross slide and a machine tool. Background Art
[0002] The cross slide is a crucial component of machine tool construction, allowing the platform to move precisely in two perpendicular directions (typically the X and Y axes). This design utilizes a sliding system installed in both the horizontal and vertical directions, allowing the machining platform to be flexibly positioned within a plane, meeting the demands of multi-dimensional machining operations.
[0003] In order to ensure the positioning accuracy, stability and load capacity of the existing cross slide when the slide is in use, screw transmission is mostly adopted. When screw transmission is used, the screw is usually arranged in the center of the slide to avoid uneven force during screw transmission and vibration during operation. Affected by the structural design, if a corresponding protective cover is not set on the slide, the centrally arranged screw has no obstruction above and is in an exposed state. The debris generated during processing and the cutting fluid used are easy to contact with the transmission parts, and the machine tool is easily damaged by human contact during processing and maintenance. For example, when heavy cutting force or external force impact is applied, the transmission structure may undergo slight deformation, and the debris adhered to the screw will wear out during long-term use, thereby reducing the service life of the components, causing an increase in processing costs, and may cause the positioning accuracy and repeatability of the cross slide to be reduced, affecting the dimensional accuracy and surface quality of the processed parts.

The side curtain 9 in the middle section is in a fixed state. When the slide 6 moves, the side curtains 9 on the left and right sides will expand or gather with the movement of the slide 6, so that the cavity opening of the base 3 is always blocked. During processing, due to the position, part of the cutting waste and the used coolant will fall down into the base 3. By arranging the side curtains 9 for blocking the transmission parts on the base 3 where chips and coolant are easily accumulated, the interference and damage of the processing environment to the transmission parts in the chamber can be effectively reduced.
