The invention discloses a tool holder with anti-pinching function for a numerically controlled machine tool, which comprises a lower tool holder, an upper tool holder and a bolt handwheel. Both the upper surface and the rear surface of the lower tool rest are provided with cooling channels, the cooling channels of the upper tool rest and the lower tool rest are connected, and the top outer surface of the lower tool rest is fixedly connected with a bonding layer, and the first tapered The gears are located inside the upper tool holder. The CNC machine tool uses a tool holder with an anti-pinch function. When the bolt handwheel is tightened, it will squeeze the tool. However, because the connecting layer on the bolt handwheel is made of silicone rubber, the silicone rubber material has high flexibility. It can increase the friction between the bolt handwheel and the tool, but the hardness is smaller than that of the tool, so the tool will not be pinched, and the bonding layer is made of copper material, and the hardness of the copper material is also smaller than that of the tool , Effectively protect the tool.
Description
technical field [0001] The invention relates to the technical field related to numerical control machine tools, in particular to a tool holder with pinching prevention function for numerical control machine tools. Background technique [0002] CNC machine tools are very common equipment in industrial production, mold production and some mechanical production, such as CNC lathes, CNC milling machines and CNC machining centers, etc., and tool holders are specially used for placing tools in these machine tools The material is fixed by the tool holder to facilitate the processing of the material by the tool, but the tool holder has some disadvantages: [0003] First, as mentioned above, during processing, it is generally necessary to place the tool through the tool holder, and then lock the tool through the bolt, but because the tightening of the bolt is easy to directly cause damage to the outer surface of the tool, it is easy to cause the tool to be damaged. low stability; ...
