Hinge synchronization type telescopic protecting cover

Abstract

The invention relates to a machining protecting device, in particular to a hinge synchronization type telescopic protecting cover which comprises a telescopic protecting cover body, an upper guide rail, a middle guide rail and a lower guide rail. All the guide rails are installed on a machine tool engine. The telescopic protecting cover is of an L shape. An upper guide wheel and a lower guide wheel are arranged at two ends of the upper side and the lower side of the telescopic protecting cover body correspondingly. The upper guide wheel travels along the upper guide rail. The lower guide wheel travels along the lower guide rail. A middle guide wheel is arranged at the right-angle end of the middle portion of the telescopic protecting cover body. The middle guide wheel travels along the middle guide rail. An upper hinge and a lower hinge are arranged on the outer sides of the two straight edges of the telescopic protecting cover correspondingly. Three independent guide rails are adopted for supporting, two synchronous hinges are adopted for driving, and the hinge synchronization type telescopic protecting cover is good in guide performance and reliable in protection.

Description

technical field [0001] The invention relates to a machine-added protective device, in particular to a hinge synchronous telescopic protective cover. Background technique [0002] For the inner protective cover of the CNC machine tool of the turning-milling compound center, the width after expansion must be large, and the width must be small after contraction, which is difficult to design, especially for the main engine of the machine tool with two turrets. When the cutter head on the turret is at the extreme position, it is required to fit together as close as possible to ensure the smooth turning of the parts. Therefore, the inner protective cover of this type of machine tool has more protective layers and each layer is narrower. , so the orientation is poor when stretching, and measures need to be taken for further improvement. Contents of the invention [0003] The object of the present invention is to provide a hinge synchronous telescopic protective cover, the overal...
