Measuring device and method suitable for equal-height guide rails

Abstract

The invention discloses a measuring device and method suitable for equal-height guide rails. The method comprises the steps of adjusting a left bed body to be horizontal, achieving the levelness of afirst guide rail and a second guide rail of the left bed body, and meeting the straightness requirements; installing a right bed body, roughly adjusting guide rails of the right bed body to be horizontal, and after adjustment, installing a first steel wire fixing frame on the outer side of the first guide rail of the left bed body and a second steel wire fixing frame on the outer side of the fourth guide rail of the right bed body; installing a steel wire on the first steel wire fixing frame and the second steel wire fixing frame, and then straightening the steel wire through a lead weight; measuring the distance from the first guide rail of the left bed body to the steel wire as high as the distance from the fourth guide rail of the right bed body to the steel wire; taking the second guide rail of the left bed body as a reference guide rail, and installing a reading microscope on the second guide rail and aligning with the steel wire. The device is used for coplanarity and equal height of large-span guide rails, the method is simple and convenient, the cost is low, the device can work in a strong magnetic interference environment, and the adjustment difficulty is greatly reduced.

Description

technical field [0001] The invention relates to the technical fields of machine tool manufacturing and engineering machinery manufacturing, in particular to a measuring device and method suitable for contour contours of guide rails. Background technique [0002] In the manufacturing process of mechanical equipment, for equipment with long-span guide rails, such as large-scale gantry CNC machine tools, large-span cranes in construction machinery, etc., in the assembly and debugging of machine tools, the coplanar adjustment of guide rails and columns on both sides is the most important factor affecting the overall An important test item for accuracy. The coplanarity of the guide rails on both sides directly affects the working accuracy, fast moving speed and service life. Therefore, adjusting the contour of the guide rails on both sides has become an important part of equipment precision adjustment. [0003] The current method of measuring the contour of long-span guide rail...

AI Technical Summary

Problems solved by technology

[0003] The current method of measuring the contour of long-span guide rails is to use a laser tracker, which costs millions of dollars and is expensive, resulting in high manufacturing costs for large-span equipment

[0004] The laser tracker cannot work in a strong magnetic environment, resulting in the inability to measure the contour and coplanarity of the guide rail in a strong magnetic interference environment
