Technical Field

[0001] The invention relates to the technical field of mechanical processing, and in particular to a double-swing wire cutting machine tool suitable for precision cutting of large-scale thin optical devices and general large-scale hard and brittle material devices. Background Art

[0002] The main defect of wire cutting machines on the market is that the size of the workpiece is limited. Generally, they are only suitable for processing small and medium-sized parts. However, for large hard and brittle parts, such as the slice cutting of large optical glass lenses with a diameter of more than 1 meter, they cannot be processed due to the large size of the parts. In addition, some wire cutting machines (such as Figure 1 The cutting method of the invention (shown in the figure) is to set a swinging disk 6 driven by a motor on the working driving platform 5, and set multiple wire guide wheels 301 on the swinging disk 6, and a cutting wire 203 is wound around the multiple wire guide wheels 301. This cutting structure is to cut the cutting wire 203 on the wire guide wheel 301 by the swinging of the swinging disk 6. The swinging disk 6, the wire guide wheel 301, and the cutting wire 203 are involved in the movement as a whole. The structure is bulky and consumes electric energy. In addition, when cutting and processing large hard and brittle material devices 7, this cutting structure is easy to make the large hard and brittle material devices 7 contact with the wire guide wheel 301, forming interference of mutual movement, resulting in the inability to process large hard and brittle material devices. Therefore, it is urgent for those skilled in the art to conduct research and improvement on the above-mentioned problems and propose a double swing wire cutting machine tool. Summary of the invention

The swing rod is symmetrically arranged on the base frame, and the swing rod is connected to the base frame with the midpoint of its length direction as a rotation support point. The swing guide pair includes a bearing guide and a slider. The slider is symmetrically arranged on the swing rod, and the bearing guide is arranged on the base frame and is adaptively connected to the slider. The end of the swing rod is hinged with the end of the swing connecting rod and a wire guide wheel is arranged at the end of the swing rod. One end of the cutting line is wound around the wire unwinding drum, and the other end is guided by the wire guide wheel and wound around the wire collecting drum.

[0008] Preferably, the swing link is arranged on one side of the base frame and is hinged to the swing rod, and one end of the swing link is transmission-connected to the output shaft end of the drive motor.

[0009] Preferably, the guide member is an arc-shaped guide rail.
