Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a numerical control machine tool that is easy to move and use. Background Art

[0002] CNC machine tools are high-precision machines that perform automated processing using a computerized digital control system. They logically process programs specified by control codes or other symbolic instructions, decode them, and represent them as coded numbers, which are then input into the CNC device via an information carrier. CNC machine tools effectively address the challenges of machining complex, precise, small-batch, and high-variety parts. Existing CNC machine tools are typically fixed in a designated location, making them difficult to move when needed. This increases the workload on workers and hinders their effectiveness.

[0003] According to the description of a CNC machine tool that is easy to use and is published on the patent website (authorization announcement number: CN214641761U), the CNC machine tool that is easy to use and is easy to use and is easy to use includes "CNC machine tool body, mounting plate, hand frame" etc. to move the CNC machine tool body.

[0004] In view of the above description, the applicant believes that the following problems exist:

[0005] The CNC machine tool which is easy to move utilizes the CNC machine tool body, mounting plate, hand stand and the like to move the CNC machine tool body. During the use of the CNC machine tool, when it needs to be moved, it is moved by the universal wheels at the bottom of the body frame. When the movement is completed, it is limited by the locking mechanism of the universal wheels themselves. Since the CNC machine tool has a certain weight and generates vibrations during operation, the stability of the universal wheels cannot be guaranteed by the locking structure alone, resulting in low safety and inability to ensure the stability of the CNC machine tool. Therefore, it is necessary to improve the CNC machine tool. Utility Model Content
