Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool spindle technology, and in particular to a support frame for a five-axis CNC machine tool. Background Technology

[0002] The base of a five-axis CNC machine tool support frame is typically made of high-strength cast iron and welded steel. The cast iron base has good shock absorption and stability, absorbing vibrations generated during machine tool operation and reducing the impact on machining accuracy. The welded steel base has high strength and toughness, and can withstand greater weight and impact. The connection between the support column, the base, and the machine tool table is usually achieved through high-precision bolts and locating keys. The specifications and strength of the bolts are selected based on the weight of the machine tool and the stress conditions during operation. High-strength bolts and locating keys are used to ensure the circumferential positioning accuracy of the support column and other components, ensuring that the support column can accurately transmit various forces during machine tool operation.

[0003] One of the main functions of a five-axis CNC machine tool support frame is to support the weight of the machine tool. Due to the complex structure of five-axis machine tools, which include multiple motion axes, motors, and tool magazine components, they are quite heavy. The support frame can stably support machine tools weighing several tons or even tens of tons. Some large five-axis linkage machining centers can have support frames that can support the weight of ten tons of machine tools, ensuring that the machine tool will not sink or deform due to its own weight during operation. However, during the machining process of existing five-axis CNC machine tools, the cutting force between the tool and the workpiece will generate vibration. If the support frame does not provide support, the machine tool cannot be stably supported, and these vibrations cannot be effectively suppressed. As a result, when milling complex curved surfaces at high speed, the machine tool will shake significantly due to vibration, leading to a decrease in the quality of the machined surface, the appearance of chatter marks, and a serious impact on the surface roughness of the parts, making them unable to meet the requirements of precision machining. This reduces the efficiency of the equipment. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a five-axis CNC machine tool support frame, which aims to improve the problem in the prior art where the cutting force between the tool and the workpiece will generate vibration during the machining process of a five-axis CNC machine tool. If the support frame does not provide support, the machine tool cannot be stably supported, resulting in a decrease in the quality of the machined surface, the appearance of vibration marks, and a serious impact on the surface roughness of the parts.
