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 with an anti-collision tool mechanism. Background Art

[0002] Before processing, the CNC machine tool needs to input a command with movement parameters for the tool head. The programmed tool cutting path is greater than the distance between the tool and the workpiece fixture. After the tool is running, it will cause it to collide with the workpiece fixture, causing the tool to hit the tool, break the tool, and even cause damage to the fixture. Therefore, a CNC machine tool with an anti-collision tool mechanism is needed.

[0003] According to the description of a high-precision CNC machine tool with an anti-collision tool disclosed in the patent website (authorization announcement number: CN116871970B), "The present invention relates to the technical field of CNC machine tools, and specifically to a high-precision CNC machine tool with an anti-collision tool, comprising a moving mechanism and a tool holder arranged on the moving mechanism, the tool holder is provided with a rotating drive motor, a rotating shaft and an anti-collision mechanism, the anti-collision mechanism comprises a fixed shaft, a buffer cylinder and a first transmission shaft; the upward movement of the buffer cylinder along the axis of the fixed shaft and its own rotation can effectively remove the impact force generated by the collision, reduce the damage to the rotating shaft caused by the collision between the tool and the fixture, reduce the impact of the collision on the equipment, extend the service life of the equipment, ensure the processing accuracy of the equipment, enable the equipment to cope with the forces generated when the collision occurs in more situations, and improve the application scenarios of the device. At the same time, the first transmission shaft is driven by the rotating shaft, so that the main shaft of the tool holder, that is, the rotating shaft, will not directly collide with the fixture, thereby reducing the damage to the equipment caused by the damage to the main shaft. The first transmission shaft is convenient for replacement and the repair cost is low."

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

[0005] During use, the utility model can effectively remove the impact force generated by the collision through the upward movement of the buffer cylinder along the axis of the fixed shaft and its own rotation, and can reduce the damage to the rotating shaft caused by the collision between the tool and the fixture. However, in actual use, the device can reduce the collision damage to a certain extent, but the wear of the tool will affect the processing quality and efficiency of the workpiece. The staff needs to frequently replace the tool manually, which reduces the work efficiency. In addition, the damaged tool will splatter everywhere, which can easily threaten the safety of the operator. Therefore, it is necessary to improve a CNC machine tool with an anti-collision tool mechanism to solve the above problems. Utility Model Content
