Abstract

The invention relates to a support span adjusting device for a rotating assembly and a machine tool. The support span adjusting device comprises an execution unit and control units, wherein the execution unit is arranged on a carrying assembly; the execution unit comprises first telescopic assemblies capable of pushing a left bearing assembly to slide rightwards when extending, second telescopic assemblies capable of pushing the left bearing assembly to slide leftwards when extending, third telescopic assemblies capable of pushing a right bearing assembly to slide rightwards when extending, and / or fourth telescopic assemblies capable of pushing the right bearing assembly to slide leftwards when extending; the control units are connected to the first telescopic assemblies, the second telescopic assemblies, the third telescopic assemblies and / or the fourth telescopic assemblies; and the control units can at least control the extension movement of the telescopic assemblies. The support span adjusting device is capable of solving the problem of the difficulty in adjusting a support span of the rotating assembly, prolonging the service life of the rotating assembly, and avoiding the situation that the machining quality and production efficiency of the machine tool are affected by improper support spans.

Description

Technical field

[0001] The present invention belongs to the technical field of machine tools, and more particularly to a support span adjustment device and machine tool for rotating the assembly.Background technique

[0002] The rotating assembly represented by the machine tool spindle includes a carrier assembly, and is provided in the carrier assembly and the left bearing assembly and the right bearing assembly spaced apart from the left-right direction, and the rotation shaft in the left-right direction and the right bearing assembly is loaded along the left-right direction. . In the rotating assembly, the relative distance between the left bearing assembly and the right bearing assembly is referred to as a support span, and the support span is an important parameter affecting the stiffness performance of the rotation component and the resistance performance. Once the support span of the rotating assembly is easily reduced. The service life of the rotating component does even affect th...
