Embodiment 1

[0044] See Figure 1 - Figure 4 In this embodiment, the present embodiment discloses a high-speed electrical spindle transient movable load analog loading method, including the following steps:

[0045] (1) Adjust the air gap between the arc-shaped electromagnet 3-6 and the radial force shaft 3-2 by the radial force air gap adjustment mechanism 6, and adjust the planar electromagnet 4-4 and the shaft through the axial force air gap adjustment mechanism 7. The air gap between the load disk 4-1; and determine the air gap between the curved electromagnet 3-6 and the radial force shaft 3-2 and the planar electromagnet 4-4 and the axial load disk 4-1. Air gap;

[0046] (2) The detection device is operating normally. If it is normal, the industrial computer starts to work, if not normal, check the state of the components until the device is operating normally;

[0047] (3) After the industrial control machine transmits the control command, after the A / D converter is converted, it is se...

Embodiment 2

[0074] The other configuration in this embodiment is the same as that of the first embodiment, and there is different, and one end of the adjusted rod 9 is rotated to the radial force base 3-1, and the other end and the axial force base 4. -2 is connected by a thread. By rotating the adjustment rod 9, the driving axial force base 4-2 can move along the guide groove 1-1 under the action of the threaded connection, in which the axial load disc 4-1 is in an air of the plane electromagnet 4-4. Gap adjustment.

Embodiment 3

[0076]The other configuration in this embodiment is the same as that of the first embodiment, and the difference is that the specific structure of the axial force air gap adjustment mechanism 7 is the same as the specific structure of the radial air gap adjustment mechanism 6, all by adjusting the bolt adjustment shaft.The position of the planar electromagnet 4-4 and the axial load tray 4-1 is adjusted to the position of the magnetic force shaft 4-3 in the adjustment hole 6-1 of the axial force base 4-2, and then by the lock nut6-2 lock the axial magnetic force shaft 4-3 on the axial force base 4-2.

Abstract

The invention discloses a high-speed motorized spindle transient dynamic load simulation loading method and device. The method comprises the steps that an air gap between an arc electromagnet and a radial force shaft is adjusted through a radial force air gap adjusting mechanism, and an air gap between a plane electromagnet and an axial loading disc is adjusted through an axial force air gap adjusting mechanism; the industrial personal computer controls the frequency converter to start working after passing through the A / D converter, and the rotating speed of the motorized spindle is determined; the industrial personal computer controls the programmable power supply to change the current of the arc-shaped electromagnet and the planar electromagnet, the arc-shaped electromagnet carries out radial force loading on the radial force shaft, and the planar electromagnet carries out axial force loading on the axial loading disc; the radial force sensor collects the real-time load of the radial force shaft and sends the real-time load to the industrial personal computer; the axial force sensor collects the real-time load of the axial loading disc and sends the real-time load to the industrial personal computer. According to the method, the air gap between the electromagnet and the loading object can be flexibly adjusted, and the loading function of applying radial force and axial force at the same time can be achieved.

Description

Technical field [0001] The present invention relates to the field of CNC machinery, and more particularly to a high-speed electric spindle transient movable load analog loading method and apparatus. Background technique [0002] The high-end CNC machine tool is one of the technical foundations and development directions of the equipment manufacturing. The high-end CNC machine tool is high and low is a sign of a highly low level of manufacturing a country. As one of the key functional components of the high-end CNC machine, the electric spindle is one of the high-end electric spindles, which is unpredictable to detect this important link. The reliability of the electric spindle has an important impact on the reliability level of the whole machine, and its dynamic characteristics determine the speed, accuracy and reliability of machine tool processing. [0003] The force load applied by the existing test method tends to obtain according to the experience or load spectrometry, the l...
