Embodiment Construction

[0022] There are two processing methods for fixed guide rail components: split processing and integral processing. The use of split processing is that since the two guide rails are symmetrical structures, in order to ensure their dimensional consistency, the two guide rails are processed as a whole before grinding, and then divided into two by wire cutting. Grind the connecting reference planes of the two guide rails and the connecting plate, and connect the guide rails and the connecting plate together with screws on the reference plate. During the connection process, as long as the bottom planes of the three are coplanar and the end surfaces of one side are coplanar, the working planes of the guide rails are basically coplanar. The assembled fixed guide rail components are uniformly aged to reduce the internal stress generated by the screw connection and improve the overall dimensional stability of the components. Integral processing is to process the guide rail and connect...

Abstract

The invention provides a high-precision positioning device for improving the precision of helix measurement of a straight-tooth master gear and an adjusting method of the high-precision positioning device.A double-V-shaped block positioning mode with one face of each V-shaped block fixed and the other face of each V-shaped block adjustable is adopted; one side face of each V-shaped block is a fixed plane inclining by 20 degrees and makes line contact with a measuring mandrel, and the other side face of each V-shaped block is a cylindrical surface with the axis perpendicular to the fixed plane and makes point contact with the measuring mandrel, wherein the position of the other side face can be finely adjusted.The adjustment reference of the device, the gear installation reference and the helix measurement reference are uniform.The combined positioning error of the high-precision positioning device for improving the precision of helix measurement of a straight-tooth master gear can be reduced to 0.5 micrometer or below, the requirement of a grade-1-precision helix measurement device for a straight-tooth master gear for positioning precision is met, and the high-precision positioning device for improving the precision of helix measurement of a straight-tooth master gear can be applied to high-precision positioning of shaft parts and guide rail parts and has great popularization value and broad market application prospects.

Description

technical field [0001] The invention belongs to the technical field of precision machining and testing, and relates to a high-precision positioning device and an adjustment method for improving the measurement accuracy of the helical line of a straight-toothed standard gear. Background technique [0002] Gears are one of the most important basic parts of mechanical parts, especially cylindrical involute gears are widely used in conventional machinery, ground transportation, ships, aerospace, weapons, precision machine tools and instruments and other fields. The national gear standard GB / T10095.1-2008 defines 13 precision grades for gears, with grade 0 being the highest and grade 12 the lowest; the international standard for gears ISO1328-1:2013 defines 12 precision grades for gears, grade 1 being the highest and grade 12 the lowest. my country's standard gear identification regulations JJG 1008-2006 stipulates that the accuracy grade of standard gears is based on the single ...
