Problems solved by technology

However, this back-shaped protective cover can only move synchronously with the movement of the machine tool spindle when the machine tool moves, and cannot move in two or three directions at the same time. Now there are also some guide rail protective covers that move in two directions simultaneously.
Its principle is simply to combine movements in a single direction. The internal structure is simple and the volume is relatively large. It is generally only used in gantry-type CNC machining centers, and it is difficult to apply to large and medium-sized machine tools.
Telescopic steel plate guide rail protective cover (CN201520992639.2); a CNC machine tool guide rail protective cover (CN201420827924.4), which has a single structure and large limitations, and in this case, the moving distance of the machine tool spindle increases, which can realize two The guide rail protective cover that moves in both directions is also a composite structure, such as the hinged vertical guide rail protective cover (CN201410599576.4), through the combination of two mechanisms (a horizontal hinge mechanism and a longitudinal hinge mechanism) to achieve two different directions. Movement, its mass is large, it is easy to produce rigid deformation, there are many internal mechanisms, it is easy to be damaged, and the cost of the hinge is expensive

Abstract

The invention discloses an improved concentric-square-shaped machine tool protection cover. The improved concentric-square-shaped machine tool protection cover comprises a plurality of protection cover bodies being internally and externally in cup joint. A plurality of connecting mechanisms are arranged between the two adjacent protection cover bodies. Each connecting mechanism comprises a first positioning plate fixed to the protection cover body on the outer side, wherein a first sliding rail is fixed to the first positioning plate and is in sliding cup joint with a sliding block; and a second positioning plate is arranged on the protection cover body on the inner side, a second sliding rail is fixed to the second positioning plate, the second sliding rail is in sliding cup joint in the sliding block, and the first sliding rail is perpendicular to the second sliding rail. The improved concentric-square-shaped machine tool protection cover can overcome the defects in the prior art, the improved concentric-square-shaped machine tool protection cover can move in the two directions at the same time through one mechanism, on one hand, the movement distance of a machine tool spindle is reduced, the two branch movements can become a combined movement, on the other hand, unnecessary time is shortened, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of machine tool protection, in particular to an improved back-type machine tool protective cover. Background technique [0002] In order to ensure the normal processing operation of the machine tool and the personal safety of the staff, a protective cover needs to be installed outside the machine tool. Since the machining process of the machine tool involves the processing movement directions of X and Y directions, the protective cover should also be set independently in the two moving directions, which makes the structure of the protective cover very complicated, and there are many defects in the cooperation. . The applicant once proposed an invention patent application CN106141799A in response to this problem. By setting a back-shaped protective cover, the protective structure of the machine tool is simplified, the processing cost is low, and the use and maintenance are convenient. However, this back-sha...
