Abstract

The invention discloses a tool holder with an anti-pinch function for a numerical control machine tool. The tool holder comprises a lower tool holder, an upper tool holder and bolt hand wheels. The upper surface of the lower tool holder is connected with the upper tool holder, the upper surfaces and the rear surfaces of the upper tool holder and the lower tool holder are provided with cooling channels, the cooling channels of the upper tool holder and the lower tool holder communicate, the outer surface of the top end of the lower tool holder is fixedly connected with an attachment layer, andfirst bevel gears are located in the upper tool holder. According to the tool holder with an anti-pinch function for the numerical control machine tool, in the screwing process of the bolt hand wheels, a tool can be squeezed, however, as connecting layers on the bolt hand wheels are made of silicone rubber with high flexibility and strength, the friction force between the bolt hand wheels and thetool can be increased, but the hardness is less than that of the tool, and thus the tool will not be pinched; and besides, the attachment layer is made of copper of which the hardness is also less than that of the tool, and thus the tool is effectively protected.

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; ...
