Abstract

The invention discloses a mounting structure and method for reducing thermal deflection of a tool tower crane, and relates to the technical field of precision machine tools. According to the technical scheme, the mounting structure for reducing the thermal deflection of the tool turret crane comprises a lathe bed, a mounting frame is arranged on the lathe bed, a lead screw is rotationally connected to the mounting frame, a driving motor for driving the lead screw to rotate is fixed to the mounting frame, a lead screw nut pair is rotationally connected to the lead screw, and a tool tower is slidably connected to the mounting frame. The tool tower is fixedly connected with the lead screw nut pair, a main shaft is arranged on one side of the tool tower, the main shaft is fixed to the lathe bed, the lead screw is pre-stretched to the length after the lead screw is heated and expanded, and an adjusting mechanism is further arranged on the lathe bed, the mounting frame, the tool tower and the main shaft. The adjusting mechanism detects the temperature change of each component, calculates and generates a correction quantity and feeds the correction quantity back to the NC of the machine tool for adjustment. The structure is reasonable, the influence caused by thermal expansion of the machine tool is effectively reduced, and the machining precision of the machine tool is greatly improved.
