Description

Technical Field

[0001] The utility model relates to a detection device, in particular to a tool detection device for a numerical control milling machine. Background Art

[0002] CNC milling is the process of automatically and precisely cutting and shaping materials according to preset programs through computer digital control technology.

[0003] During the CNC milling process, the cutting performance and length of the tool will gradually decrease with the use time. This change may be caused by wear, temperature changes or mechanical stress. If the length is not detected, the actual length of the tool may deviate from the length set in the CNC system, resulting in inaccurate processing dimensions. The existing technology usually places the tool directly on a plane for detection without fixing the tool, so it is very easy to offset during detection, thus affecting the detection effect. If the tool length detection is inaccurate, it will lead to errors in tool size, reduced surface quality, damage, increased risk of collision, and reduced production efficiency, which will seriously affect the quality and efficiency of CNC milling processing.

[0004] Therefore, it is necessary to design a CNC milling machine tool detection device that can fix the tool during the re-detection process to prevent the tool from shifting. Utility Model Content
