It is to be understood that the drawings are not to scale as the actual practice of the invention, but are for illustrative purposes and are not drawn to scale.

In the prior art, a magnetic base of a dial indicator needs to be fixed on a magnetic conduction plate with a plane. The centering machine is provided with a horizontal main shaft 99 and an adjusting sleeve 98 positioned in front of the main shaft, the adjusting sleeve 98 needs to be concentric with the horizontal main shaft 99, but the horizontal main shaft 99 does not have a plane, so that a magnetic seat of a dial indicator cannot be fixed on the horizontal main shaft 99, and the coaxiality of the horizontal main shaft 99 and the adjusting sleeve 98 cannot be detected.

Based on the above problem, please refer to fig. 1-3, the present invention provides a calibrating device 100 for calibrating the coaxiality between a horizontal spindle 99 and an adjusting sleeve 98 of a core-moving machine, wherein the calibrating device 100 comprises a sleeve 10, a connecting member 20 and a dial indicator 30. The dial indicator 30 may be a gauge head part of a lever dial indicator.

The sleeve 10 is intended to be fixed to the horizontal spindle 99. For example, the sleeve 10 includes a socket 11 connected to the horizontal spindle, and in the present embodiment, the socket 11 is an internal thread. The horizontal main shaft 99 is provided with external teeth, and the inner diameter of the sleeve 10 is matched with the outer diameter of the horizontal main shaft 99, so that the sleeve 10 can be sleeved on the periphery of the horizontal main shaft 99, and the calibration device 100 can rotate along with the rotation of the horizontal main shaft 99. In some other embodiments, the sleeve 10 is removably received around the outer periphery of the horizontal spindle 99, for example, the sleeve 10 includes a clamp band received around the outer periphery of the horizontal spindle 99 and a fastener that locks the clamp band to the horizontal spindle 99.

In order to prevent the horizontal main shaft 99 from being worn when the sleeve 10 is attached to the horizontal main shaft 99, the material hardness of the sleeve 11 is smaller than that of the horizontal main shaft 99, for example, the horizontal main shaft 99 is made of 45 steel, and the sleeve 11 is made of aluminum.

One end of the connector 20 is connected to one end of the sleeve 10. In order to prevent the sleeve 10 from passing through the main shaft, a limiting portion 13 is provided at one end of the sleeve 10 close to the connecting member 20, and the limiting portion 13 protrudes toward the rotation axis direction of the sleeve 10. When one end of the sleeve 10 close to the connecting piece 20 is matched with one end of the horizontal main shaft 99, the limiting part 13 is abutted against one end of the horizontal main shaft 99, so that the sleeve 10 is prevented from moving towards the other end of the horizontal main shaft 99 continuously, and the sleeve 10 is prevented from penetrating through the main shaft.

The connecting piece 20 comprises a clamping piece 21 and an adjusting piece 22, the connecting piece 20 is provided with a rotating hole 218 connected with the sleeve 10 and a mounting hole 214 used for accommodating the dial indicator 30, and the linear distance between the rotating axis of the rotating hole 218 and the axis of the mounting hole 214 is 10-50mm. Compared with the existing dial indicator, the arm length of the existing dial indicator is about 300mm, the shorter the arm length is, the higher the accuracy of measuring the coaxiality between the horizontal spindle 99 and the adjusting sleeve 98 is, and the linear distance between the axis of the rotating shaft of the rotating hole 218 and the axis of the mounting hole 214 is smaller than the arm length of the existing dial indicator, so that the calibration accuracy is higher.

The coupling 20 is used to couple the dial gauge 30 to the sleeve 10. For example, one end of the connector 20 is connected to one end of the sleeve 10, and the connector 20 is also connected to the dial indicator 30.

It should be noted that, even if the rotation radius of the dial indicator 30 is not equal to the rotation radius of the sleeve 10, the coaxiality of the horizontal spindle 99 and the adjusting sleeve 98 can be detected by the calibrating device 100, because although the rotation radius of the dial indicator 30 is greater than the rotation radius of the sleeve 10 or the rotation radius of the sleeve 10 is greater than the rotation radius of the dial indicator 30, the rotation axis of the sleeve 10 is collinear with the rotation axis of the dial indicator 30, as long as the sleeve 10 rotates once, the dial indicator 30 rotates once, four points are selected on the rotation path of the dial indicator 30, four corresponding points on the adjusting sleeve 98 are found, if the difference between the coordinates of the four corresponding points on the adjusting sleeve 98 and the coordinates of the four points of the dial indicator 30 is equal, it can be determined that the horizontal spindle 99 and the adjusting sleeve 98 are coaxial, and therefore, the rotation radius of the sleeve 10 is not required to be equal to the rotation radius of the dial indicator 30.

The connecting piece 20 can rotate relative to the sleeve 10 in the axial direction towards or away from the sleeve 10, so that the relative position between the dial indicator 30 and the sleeve 10 can be adjusted, and the flexibility of the dial indicator 30 is improved.

For example, one end of the sleeve 10 is provided with a mounting groove 12, and one end of the connection member 20 is rotatably mounted to a groove wall of the mounting groove 12. Thereby facilitating the adjustment of the position of the coupling element 20 relative to the sleeve 10 and improving the flexibility of the coupling element 20. In some preferred embodiments, the connecting member 20 is rotatably connected to the sleeve 10, and the axis of the rotating shaft is perpendicular to the axis of the sleeve 10.
