[0002] The machine tool spindle refers to the axis on the machine tool that drives the workpiece or tool to rotate. It is usually composed of a spindle, bearings, and transmission parts. It is mainly used to support transmission parts such as gears and pulleys in the machine, and to transmit motion and torque. For example, the machine tool spindle needs to be tested with a tool holder before the machine tool vertical spindle is used.

[0003] When testing the vertical spindle, the existing tool holder often places the spindle flat, and fixes the tool holder to the flange outside the spindle by screws for testing. During the tooling process, the force point is on the core shaft, and relative movement will occur between the core shaft and the spindle, causing stress on the bearings, which can easily damage the bearings. Moreover, when the tool holder is tested, the tool holder is in direct contact with the spindle shaft body, which can easily scratch the appearance of the spindle, causing inconvenience to people's use. Therefore, a tool holder for testing the vertical spindle of a machine tool has been specifically introduced. Utility Model Content
