Embodiment 1

[0019] Such as figure 1 As shown, a CNC machine tool spindle rotation accuracy verification device includes a shaft sleeve 4 and a sensor 3 arranged on the shaft sleeve 4, the sensor 3 is more than one, 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 sensor 3 is...

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 numerically-controlled machine tool spindle rotation precision verifying unit. The unit comprises a shaft sleeve and more than one sensor arranged on the shaft sleeve, wherein the sensors are all fixed to the side wall surface of the shaft sleeve and are all electric induction sensors, and the measurement points of the sensors are not located on the same straight line; a base is fixed to any end of the shaft sleeve, and the base is of a flange-shaped structure provided with a magnetic coil inside. By the adoption of the unit, multiple parameters of a spindle can be measured and analyzed at the same time conveniently, measurement precision is not affected by environment humidity, and the unit can be installed on the spindle conveniently.

Description

technical field [0001] The invention relates to the field of testing equipment for the spindle of a machine tool, in particular to a device for checking the rotation accuracy of the spindle of a numerically controlled machine tool. 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 o...
