Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and in particular to a safe feeding CNC machine tool. Background Technology

[0002] In the automobile manufacturing process, CNC machine tools are often used to process important parts such as engine parts and body frames. Due to the complexity of these parts and the large production batch, the requirements for processing accuracy are high. Automatic feeding can reduce the operation of workers in high-precision processing, improve the automation level of the production line, reduce human intervention, ensure the stability of processing accuracy, and meet the needs of large-scale production due to high production efficiency.

[0003] The structure of a safe feeding CNC machine tool includes a cutting tool, a cylinder, a storage platform, etc. The safe feeding CNC machine tool works together with a precise CNC system, an automated feeding device, and multiple safety protection measures to ensure the operational safety during the feeding process. Through real-time monitoring, fault alarms, and automatic shutdown, it effectively avoids accidents and personal injury during the production process and improves production efficiency and reliability.

[0004] In the existing technology, some CNC machine tools use manual loading of workpieces onto the machine tool's worktable, which poses certain safety hazards. During manual loading, operators need to work at close range while the machine tool is running, which can easily lead to misoperation and collisions with moving parts of the machine tool, resulting in personal injury. This not only reduces production efficiency but also increases the instability factors in the production process. Therefore, a safe loading CNC machine tool is proposed to solve the above problems.
