Abstract
The invention belongs to the technical field of machine tools, and particularly relates to a flange assembly and a machine tool. The invention aims to solve the problems that the assembly process of a BC double-shaft numerical control machine tool is complex and the efficiency is low due to repeated disassembly, assembly and reprocessing of a swinging basket at present. In the flange assembly and the machine tool provided by the invention, the flange assembly comprises a flange body and an adjusting mechanism for connecting the flange body to an upright post, wherein the adjusting mechanism comprises a fixing nut, an adjusting sleeve and a screw; when the fixing nut rotates towards the upright post, the length of the small-diameter end of the adjusting sleeve extending out of the first step hole of the flange body is increased; when the fixing nut rotates back to the stand column, the length of the small-diameter end of the first step hole of the flange body, which extends out of the adjusting sleeve, is reduced, and therefore the gap between the flange and the stand column is adjusted. Therefore, the adjustment of the parallelism of the motor of the B axis and the Y axis of the machine tool and the perpendicularity of the motor of the B axis and the X axis can be realized only by adjusting the adjusting mechanism at the corresponding position.
