Description

Technical Field

[0001] The present invention belongs to the technical field of machining center machine tools, and in particular relates to an open double-sliding door machine tool protective structure. Background Art

[0002] Invention CN101837556A proposes a pneumatically controlled double-door protective device. However, the pneumatically controlled double-door protective device provided in this patent does not take into account the needs of existing users for processing large workpieces. Therefore, the pneumatically controlled double-door protective device is not suitable for processing large workpieces or machine tools with large working strokes.

[0003] Invention CN117697527A proposes a protective door structure for a machine tool, which relates to the technical field of protective door structures. The present invention includes a machine tool housing, a side wall of the machine tool housing is provided with a protective opening, the protective opening is communicated with the inner side of the machine tool housing, a protective door device is provided inside the protective opening, and the protective door device includes two sets of linear guide rails and two arc guide rails. The present invention not only can automatically complete the opening and closing of the first protective door through the provision of the protective door device, thereby making the opening and closing of the first protective door simpler and more convenient, but also can hide the first protective door from the inner side of the machine tool housing when it is opened, thereby avoiding the first protective door protruding from the side wall of the machine tool housing when it is opened. The first protective door protruding from the side wall of the machine tool housing can affect the normal work of the staff, and also avoid the safety hazard of the staff being injured by the first protective door protruding from the side wall of the machine tool housing. However, invention CN117697527A provides a machine tool housing. When the machine tool is too large, the machine tool cannot be placed in the housing. The protective door structure of this invention cannot meet the diversified market demand, the different sizes of products processed by customers, and the large working stroke of the machine tool.

[0004] Market demand is diverse, and the products processed by customers vary in size. Automated production lines incorporate a wide variety of machining centers. Machining centers used for small parts are relatively small, and the machine tool processing chambers are all designed with closed, fully guarded construction. However, if the workpieces are large, the machine tool is large, and the machine tool has a long working stroke, using closed, fully guarded construction will not allow the machine tool to fit within the protective housing for small parts. Different machine tool protection mechanisms must be manufactured based on the actual size of each machine tool, which is costly and has a limited scope of application. Summary of the Invention
