Embodiment Construction

[0044] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0045] figure 1 The first specific embodiment of the present invention is shown, a flexible adjustment device for the rotation accuracy of the main bearing of a machine tool, which mainly includes the main shaft A of the machine tool, the fixing sleeve B of the main bearing, the main bearing, and the flexible fixed inner ring 4 .

[0046] The machine tool spindle A is fixed in the main bearing fixed sleeve B through the main bearing. The main bearing fixing sleeve B can be other structural components of the machine tool.

[0047] The main bearing mainly includes a bearing inner ring 1 , a bearing outer ring 2 and bearing balls 3 .

[0048] The flexible fixed inner ring 4 is arranged between the main shaft A and the bearing inner ring 1 . The material hardness of the flexible fixed inner ring 4 is lower than the material hardness of the main shaft A and the material...

Abstract

The invention discloses a flexible adjusting device of rotating precision of a main bearing of a machine tool. The flexible adjusting device mainly comprises a machine tool spindle, a main bearing fixing sleeve, a main bearing body, a flexible fixing inner ring and a flexible fixing outer ring, wherein the machine tool spindle is fixed in the main bearing fixing sleeve through the main bearing, and the main bearing body mainly comprises a bearing inner ring, a bearing outer ring and bearing balls; and the flexible fixing inner ring is arranged between the spindle and the bearing inner ring, material hardness of the flexible fixing inner ring is lower than that of the spindle and that of the bearing inner ring, the flexible fixing outer ring is arranged between the main bearing fixing sleeve and the bearing outer ring, and the material hardness of the flexible fixing outer ring is lower than that of the main bearing fixing sleeve and that of the bearing outer ring, According to the flexible adjusting device, the flexible fixing outer ring and the flexible fixing inner ring are arranged so as to absorb vibration of the bearing outer ring and the bearing inner ring, and the purpose ofautomatic balance of the main bearing of the machine tool is achieved.

Description

technical field [0001] The invention belongs to the technical field of precision machinery, and in particular relates to a flexible adjustment device for the rotation accuracy of the main bearing of a machine tool. Background technique [0002] All indicators of precision machine tools must reach a very high level. There are many factors that affect the machining accuracy of precision machine tools, the most basic of which is mechanical vibration. [0003] The cause of the vibration depends on the structural accuracy of the precision machine tool itself on the one hand, and on the other hand it is caused by the thermal deformation of the components. [0004] For example, the bearing balls of the main bearings of precision machine tools will cause axial and radial runout during operation, which seriously affects the machining accuracy. Precision machine tool main bearings are affected by temperature rise during actual operation, and the accuracy will also change. [0005] ...
