The head bearing seat is located at the front end of the machine tool shaft, and is responsible for supporting and positioning the front end of the shaft; the tail bearing seat is at the rear end of the shaft, and plays a role in stabilizing the rear end of the shaft and reducing vibration. The concentricity of the machine tool bearing seat needs to be corrected before use.

[0003] In the prior art, the tooling for calibrating the concentricity of the head and tail bearings of machine tool shafts mostly requires the staff to rotate the bearing seat body during calibration, and perform corrections through the dial indicator on the top of the device. When the staff rotates, it is easy to cause the bearing seat to deviate from the top of the limit mechanism, thereby affecting the correction data. Utility Model Content

[0004] The purpose of the utility model is to provide a tool for calibrating the concentricity of the head and tail bearings of a machine tool shaft, so as to solve the problem raised in the above background technology that the bearing seat is easily offset from the upper side of the limit mechanism when the operator rotates, thereby affecting the calibration data.
