Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled lathes, in particular to a space-saving sheet metal protective structure for a tailstock of a lathe. Background Art

[0002] The tailstock components of CNC lathes are sometimes equipped with a linear rail structure due to the need for automated control. The movement of the tailstock also requires the installation of a lead screw or hydraulic cylinder. These hydraulic cylinders are usually installed on the inside of the linear rail structure. Since the lathe will generate a lot of chips and cutting fluids during the machining process, these chips and cutting fluids can easily fall to the inside of the linear rail structure and damage these hydraulic cylinders. Therefore, a fully enclosed sheet metal cover is generally used to protect them.

[0003] For machine tools with an inclined bed structure, the corresponding sheet metal guard has the same inclination angle as the bed. The chips that fall during processing will fall into the chip groove along the inclined surface of the sheet metal guard under the action of gravity. For machine tools with a flat bed structure (the guide surface of the machine tool feed axis is parallel to the horizontal plane), since there is no inclination angle, in order to guide the chips to fall by themselves, the top of the sheet metal guard is generally designed to be an inverted V shape, so that the top of the guard has a very small inclination angle.

[0004] However, sheet metal guards will occupy part of the chip removal space due to their installation location, especially fully enclosed sheet metal guards, such as Figure 1 As shown, the sheet metal shield 1' is a multi-layer telescopic structure, also called an armor-like structure. This structure has good protective performance and beautiful appearance. Its overall external dimensions will increase with the increase of the stroke of the tailstock component, thereby preventing chips and cutting fluid from flowing into the inner side of the linear rail structure and causing damage to the hydraulic cylinder. The larger the external dimensions of the sheet metal shield 1', the more chip removal space it occupies on the machine tool, which will seriously cause inconvenience in chip removal.
