Abstract

Provided are a device and method for compensating X-axis moving linearity of a heavy numerical control floor type boring and milling machine. The device and method for compensating X-axis moving linearity of the heavy numerical control floor type boring and milling machine mainly solve the problem that the X-axis moving linearity of an existing heavy floor type boring and milling machine is poor. The device and method for compensating X-axis moving linearity of the heavy numerical control floor type boring and milling machine are characterized in that the bottom of a sliding seat (1) is connected with an auxiliary supporting device (3), the bottom of the auxiliary supporting device (3) is connected with rolling wheels (6), and the rolling wheels (6) are arranged on a steel plate (7). The load of a machine body can be reduced through the device and method, the deformation of the machine body is reduced accordingly, and the X-axis linearity of the heavy floor type boring and milling machine is improved greatly.

Description

technical field [0001] The invention relates to the field of machine tools, in particular to an X-axis moving straightness compensation device and method for a heavy-duty numerically controlled floor milling and boring machine. Background technique [0002] With the update of technology, the precision requirements for heavy-duty CNC floor milling and boring machines are higher. Due to the layout of ribs inside the bed, the distance between the bed supports and the casting process of the bed, etc., the rigidity of the heavy-duty CNC floor milling and boring machine in the length direction is uneven, and the bed load is large (sliding seat, column, spindle box, etc.) The total weight of the components is about 200 tons), so that when the slide moves along the guide rail of the bed, it is prone to the problem that the deformation of the bed is inconsistent when the slide moves to different positions of the bed, which seriously affects the movement of the X-axis (slide) of the m...
