Embodiment 1

[0019] Such as figure 1 As shown, a method for resetting and correcting the spindle of a machine tool includes a shaft sleeve 4 and a sensor 3 arranged on the shaft sleeve 4. There are more than one sensor 3, and the sensors 3 are all fixed on the side wall of the shaft sleeve 4. above, and the sensors 3 are all electric induction sensors 3, and the measurement points of each sensor 3 are not located on the same straight line; any end of the shaft sleeve 4 is also fixed with a base 1, and the base 1 is a magnetic coil built in it. Flange structure.

[0020] In this embodiment, the provided shaft sleeve 4 is used to fix each sensor 3. When the shaft sleeve 4 is sleeved on the main shaft, each sensor 3 forms a plurality of non-contact sensors 3 relative to the main shaft to be measured, so that , this structure can be more conveniently installed on the main shaft of the lathe to complete the dynamic error and thermal deformation analysis of the main shaft; furthermore, the sens...

Embodiment 2

[0023] The present embodiment is further limited on the basis of embodiment 1, as figure 1 As shown, the further technical solution is: in order to facilitate the replacement of sensor 3 types or models according to specific measurement needs, the sensors 3 are provided with magnetic bases 1, and each sensor 3 is magnetically adhered to the sensor 3 by the magnetic base 1 on each On the shaft sleeve 4.

[0024] In order to enable this structure to have the function of braking the rotation of the main shaft, so as to enrich the scope of application of this structure, for example, it can be used for testing and analysis of a single main shaft that has been disengaged, and a driving part 2 is also provided between the shaft sleeve 4 and the base 1 .

Embodiment 3

[0026] This embodiment is further limited on the basis of any one of the solutions provided by the above embodiments. In order to enable this structure to conveniently complete the measurement of the inclination and deflection of the main shaft, and the error analysis on the X-axis, Y-axis and Z-axis, the The number of sensors 3 is at least five.

Abstract

The invention discloses a method for resetting and correcting the main shaft of a machine tool, which comprises a shaft sleeve and a sensor arranged on the shaft sleeve. It is an electric induction sensor, and the measurement points of each sensor are not located on the same straight line; any end of the shaft sleeve is also fixed with a base, and the base is a flange-shaped structure with a magnetic coil built in it. The invention is convenient to simultaneously measure and analyze multiple parameters of the main shaft; at the same time, the measurement accuracy is not affected by the ambient humidity; the main shaft is conveniently installed and the like.

Description

technical field [0001] The invention relates to the field of machine tool spindle test equipment, in particular to a reset correction method for the machine tool spindle. Background technique [0002] The spindle system of a lathe is one of the most critical parts of the machine tool. It directly participates in the cutting process of the machine tool through the tool. The quality of its dynamic performance and thermal deformation have an impact on the cutting shock resistance, machining accuracy and surface roughness of the machine tool. It has a great influence, that is, the performance of the lathe spindle directly affects the overall performance of the machine tool. The spindle performance tester is an important device for testing the performance of the CNC machine tool spindle and above. [0003] At the same time, the thermal deformation error of the spindle in the prior art is the main error in the movement of the machine tool, accounting for 50%-70% of the total error...
