The utility model relates to the field of machinery manufacturing, in particular to a lathe tool holder for machinery manufacturing.

Background technique

The lathe tool holder is a fixture used to clamp the lathe tool. The lathe tool is a tool used for drilling, reaming or milling. The connection between them and the tool chuck is a rigid connection. Rigid connection with the spindle of the machine tool. The main disadvantages of this connection method are: when the tool is cutting the workpiece, the vibration of the machine tool caused by external factors, the runout caused by the low rotation accuracy of the spindle, and the local hard points in the workpiece during cutting may cause the tool to break. Broken, it will bring some trouble to normal production. At the same time, under the influence of the above factors, these rigidly coupled tools will also produce certain tool marks on the cutting surface of the workpiece, thereby reducing the surface quality.
