Description

Technical Field

[0001] This utility model belongs to the field of five-axis machining technology, and in particular relates to a five-axis machining device. Background Technology

[0002] Five-axis machining is a type of CNC machine tool processing that achieves efficient and high-precision machining of complex parts through the coordinated movement of five independent coordinate axes. Five-axis machine tools can perform multi-face synchronous machining, reduce the number of workpiece clamping operations, and significantly improve machining efficiency. For example, in mold processing, five-axis linkage machine tools can shorten the processing cycle and speed up delivery. Compared with three-axis machining, five-axis technology optimizes the cutting path through multi-axis linkage, avoids interference and overcutting, and makes the machining accuracy approach submicron or even nanometer level. However, in existing five-axis machining devices, it is difficult to quickly and accurately position the parts, resulting in low machining efficiency. Therefore, a five-axis machining device is proposed.

[0003] For example, Chinese patent CN206598098U discloses a five-axis machining device. A first support base and a second support base are welded to the upper surfaces of the first and second bases, respectively. A support rotation mechanism is nested in the inner wall of a circular hole, and a power rotation mechanism is nested in the inner wall of a square hole. A motor hole is opened in the middle of the third support plate, and a rotary DD motor is nested in the inner wall of the motor hole. In this five-axis machining device, the limiting groove can adjust the installation position of the first base to accommodate devices of different specifications. The support rotation mechanism serves as a support point for A-axis movement, and the power rotation mechanism provides rotational power to drive the support rotation mechanism to rotate, thus realizing the A-axis movement of the device. The rotary DD motor realizes the B-axis movement of the device.

[0004] The aforementioned patent has the following problems:

[0005] Compared with existing five-axis fixtures, which have poor adaptability to parts of different shapes and sizes, complex clamping processes, and difficulty in quickly and accurately positioning parts, resulting in low machining efficiency, existing fixtures also have complex structures, high costs, and are difficult to maintain and repair, thus hindering large-scale production applications and reducing practicality. Therefore, we propose a five-axis machining device. Utility Model Content
