Description
Technical Field
[0001] The utility model specifically relates to the technical field of full-automatic numerically controlled machine tools, in particular to a full-automatic numerically controlled machine tool for processing metal workpieces. Background Art
[0002] Modern industry has increasingly higher requirements for product quality, production efficiency and cost control. The manufacturing industry needs more efficient and precise processing equipment to meet large-scale and diversified production needs. For example, the rapid development of the automotive industry has prompted the continuous upgrading of CNC machine tools for parts processing; CNC machine tools are automated machine tools equipped with program control systems. The advantages are high precision: very precise processing can be achieved to ensure product quality; high efficiency: a high degree of automation, continuous long-term work, greatly improving production efficiency; high flexibility: by changing programs and tools, etc., it can quickly adapt to different processing needs;
[0003] When traditional CNC machine tools are processing workpieces, they can only effectively process one workpiece at a time on the fixture table. Although the processing accuracy of the workpiece can be effectively guaranteed, after the processing of a single workpiece is completed, the workpiece needs to be disassembled and replaced. This requires a lot of man-hours during replacement, which wastes time and greatly reduces the working efficiency of the CNC machine tool.
[0004] When a traditional CNC machine tool clamps and fixes a workpiece, it can only effectively fix and process one workpiece through a fixture. Although this can realize fully automatic processing of the workpiece, some workpieces now require a short processing time. Therefore, after the workpiece is processed, the workpiece needs to be replaced. When the workpiece is replaced, the position of the workpiece needs to be re-fixed or re-positioned. This will cause the time for replacing the workpiece to be longer than the processing time of the CNC machine tool. This greatly reduces the working efficiency of the CNC machine tool and cannot effectively ensure the effective processing of continuous workpieces of the CNC machine tool.
[0005] In view of the above situation, we provide a fully automatic CNC machine tool for processing metal workpieces. In this device, a fixture table is arranged on the X-axis moving structure, a real adsorption fixture is fixedly installed between the fixture tables, and a plurality of air passages are opened on the adsorption platform, so that multiple workpieces can be fixed on the adsorption platform at the same time by means of negative pressure adsorption, and the PLC system controls the X-axis moving structure, the Y-axis moving structure and the Z-axis moving structure through the automatic program inside the electric control box, so that after the workpiece is clamped and fixed, the CNC machine tool can be fully automated for processing. During the processing, when the workpiece is not processed, the automatic program inside the electric control box is used to control the automatic tool changing assembly and the Y-axis moving structure and the Z-axis moving structure of the PLC system, so as to achieve the automatic tool changing effect, reduce the participation of staff, and greatly improve the working efficiency of the CNC machine tool.
