Therefore, the processing of high-precision large-scale mechanical parts has higher and higher requirements for machine tools, especially for boring and milling machines. It is more difficult to process large-scale parts. On the other hand, there is a deviation between the actual machining accuracy of the machine tool and the theoretical accuracy, mainly because the machine tool usually uses a square ruler or a flat ruler to compensate the straightness accuracy of the coordinate axis (usually <1000mm range). Trend changes, linear calculation, deviation from the actual value, and maintenance by equipment maintenance personnel can only debug the static accuracy of the machine tool, and with the long-term operation of the machine tool, its motion accuracy will deviate, due to the weight of the processed parts, And the different distribution positions will also affect the actual processing of parts

Embodiment Construction
[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0053] refer to Figure 1-4 , a large-scale boring and milling machine movement accuracy compensation method, which is more in line with the actual precision of the movement axis of the large-scale boring and milling machine, to ensure the processing of parts with high shape and position accuracy, including the following steps:
[0054] S1: Establish a coordinate system for the large-scale boring machine according to the direction of motion, which is the X-axis for horizontal left and right movement, the V-axis for horizontal front-back movement, and the Y-axis for vertical movement;
[0055] S2: Detect the deviation in the X-axis direction by means of a meter, and u...

The invention discloses a motion accuracy compensation method for a large-scale boring and milling machine, which is more in line with the actual accuracy of the large-scale boring and milling machine motion axis and ensures the processing of parts with high shape and position accuracy. It is the X axis for horizontal left and right movement, the V axis for horizontal front and rear, and the Y axis for vertical movement; S2: Detect the deviation of the X axis direction by the method of punching a meter, and use a feeler gauge to adjust the X axis direction to the level, after leveling The X-axis plane is used as the reference plane; S3: Compensate the other coordinate axes and the angle between the coordinate axes by means of rotating the machine tool, metering detection and feeler gauge compensation. The invention has the advantages of strong versatility, accurate compensation and simple operation.
Description
technical field [0001] The invention relates to the field of mechanical processing, in particular to a motion precision compensation method for a large boring and milling machine. Background technique [0002] With the rapid development of the machinery industry, wind power, metallurgy, shipbuilding, cement and other industries are all developing towards large-scale and precision. Therefore, the processing of high-precision large-scale mechanical parts has higher and higher requirements for machine tools, especially for boring and milling machines. It is more difficult to process large-scale parts. On the other hand, there is a deviation between the actual machining accuracy of the machine tool and the theoretical accuracy, mainly because the machine tool usually uses a square ruler or a flat ruler to compensate the straightness accuracy of the coordinate axis (usually <1000mm range). Trend changes, linear calculation, deviation from the actual value, and maintenance by ...
