Thin and long part assembling method

Abstract

The invention relates to a thin and long part assembling method. The thin and long part assembling method comprises the following steps of 1 forming position measuring holes TB4, TB5 and TB6 of a sample plate, 2 drilling three holes in a frame and using the three holes as reference holes TB1, TB2 and TB3 for establishing a reference coordinate system, 3 arranging tool balls on the holes TB1, TB2, TB3, TB4, TB5 and TB6, 4 actually measuring values of the tool balls to obtain the positions of the holes TB1, TB2 and TB3, utilizing laser tracker software to perform fitting on theoretical tool ball values and actually-measured values to obtain tool balls TB1, TB2 and TB3 and establishing a three-dimensional coordinate system with the tool balls TB1, TB2 and TB3 as references, 5 reading the actual positions of the measuring holes TB4, TB5 and TB6 through the tool balls and comparing the actual positions with theoretical positions after the coordinate system is established, adjusting the assembling position of the sample plate according to obtained difference values and finally meeting the assembling accuracy requirement. By means of the thin and long part assembling method, assembling accuracy can be improved, an assembling period can be shortened, manpower is decreased, and accordingly company's benefit is improved.

Description

technical field [0001] The invention relates to an assembly method of thin, thin and long parts, which belongs to a part positioning method. Background technique [0002] The manufacturing principle of the preliminary work makes the analog quantity transfer manufacturing method. This method is characterized by low assembly efficiency and poor precision, and requires more second-type assembly tools, such as first-level assembly platforms, spirit levels, bent plates, dial indicators, and dial indicators. Blocks, height rulers, square boxes and other tools require operators with high quality and proficiency in using these tools. E.g figure 1 with figure 2 The difficulties in the assembly of the calibration fixture are as follows: 1) The part to be positioned is a thin and slender part, which is characterized by relatively good flexibility, but its rigidity is relatively poor, and it is easy to deform, so it needs to be strengthened; 2) According to the traditional To implem...
