Assembling and adjusting method for high-precision swing mirror shafting component

Abstract

The invention provides an assembling and adjusting method for a high-precision swing mirror shafting component. The assembling and adjusting method includes the steps: (1) roughly machining each part; (2) subjecting each part to semi-finish machining; (3) assembling all the parts to form a swing mirror component to be accurately machined; (4) respectively accurately machining a left shaft and a right shaft to enable the sizes, cylindricity, end face verticality and coaxiality of the left shaft and the right shaft to meet design requirements, and then accurately machining a swing mirror placing groove of a swing mirror seat according to a left-right shaft rotary center line determined by the left shaft and the right shaft of the swing mirror component at the moment to enable the swing mirror mounting face position and the left-right shaft rotary center line to meet the design requirements on parallelism and perpendicular distance; and (5) drilling and reaming positioning pin holes on the left and on the right of a swing mirror, and performing trial assembly of shaft positioning dowels. By the assembling and adjusting method for the high-precision swing mirror shafting component, an adjusting operation process is simplified, adjusting operation difficulty can be further lowered with adjusting precision improved, and adjusting efficiency is improved.

Description

technical field [0001] The invention relates to an adjustment process of a high-precision pendulum mirror shaft assembly. Background technique [0002] Such as figure 1 , 2 As shown, the high-precision oscillating mirror shaft assembly is generally installed on a bracket, and the left and right shafts are respectively supported and rotated by bearing groups. Shaking and angle measurement accuracy requirements are high. [0003] The high-precision swing mirror shaft assembly generally consists of left shaft 1, swing mirror base 2 (stage), swing mirror 3 (equipped with instruments), and right shaft 6. The left axis, right shaft and swing mirror base rely on shaft fastening screws 4 connection, left shaft, right shaft and swing mirror seat respectively determine the relative position by two shaft positioning pins 5, guarantee the relative form and position requirement among left shaft, right shaft, swing mirror seat three. The usual technical indicators are: [0004] 1) Th...

Problems solved by technology

This kind of adjustment is not only very time-consuming, laborious and expensive, but also enlarges the size of the left and right end holes of the swing mirror base in order to meet the adjustment accuracy requirements of the swing mirror shaft assembly, but reduces the reliability of the shaft hole fit.

[0020] (3) Even if the assembly of the oscillating mirror base and the left and right shafts has been adjusted, it is very difficult to ensure the coaxiality of the left and right shafts, the perpendicularity between the end faces of the left and right shafts and the rotation centerline of the left and right shafts, and the placement groove of the oscillating mirror base The four indicators of parallelism and vertical distance to the left and right axis rotation centerline all meet the requirements, and often need to be compromised
