Problems solved by technology

However, the cost increase of this method is significant due to the difficult disassembly and assembly of many actual parts
[0007] To sum up, due to the absence of a rapid evaluation method, the existing technology has a high cost when solving the assembly problem of flange parts that are difficult to be completely interchanged

Embodiment Construction

[0045] The following are specific embodiments of the present invention, and the solutions of the present invention will be further described with reference to the accompanying drawings, but the present invention is not limited to these embodiments.

[0046] The comprehensive installation error rapid assessment method of two flange hole systems consists of the following steps (unit: mm, radian):

[0047] Step 1. Obtain geometric design parameters and measurement points.

[0048] There is a main flange and a secondary flange on the two parts to be installed; the flanges are all thin plates, and there are mounting holes with the same geometric design on the flanges; each mounting hole consists of 4 mounting holes. The mounting holes are perpendicular to the mounting surface of the flange, and are evenly distributed on a circle with a nominal diameter of 25 in the mounting surface, and the nominal size of the mounting holes is 4.

[0049] Place the mounting surface of the main fl...

Abstract

The invention relates to the field of computer-aided measurement, in particular to a mathematical-evaluation-based rapid evaluation method for comprehensive installation errors of two flange plate hole systems. The method comprises the following steps: step 1, acquiring geometric design parameters and measuring points; step 2, solving the fitting radius and the fitting azimuth deviation of each mounting hole; and step 3, solving a comprehensive installation error between primary and secondary flange plate hole systems according to the nominal diameters, the distribution circle diameters, the hole number, the fitting radius and the fitting translation error of the primary and secondary flange plate installation holes.

Description

technical field [0001] The invention relates to the field of computer-aided measurement, in particular to a method for quickly evaluating comprehensive installation errors of two flange hole systems based on mathematical evaluation. Background technique [0002] Flanges are widely used in the mechanical field. At present, the flange mainly controls the minimum gap (reflecting the assemblability) and the maximum gap (reflecting the assembly accuracy) of the two flange hole systems by controlling the size tolerance and position tolerance of the mounting hole system. [0003] If the dimensional tolerance and geometric tolerance of the design are appropriate, and the dimensional and geometric errors of the parts are in line with the design tolerances, then the assemblability and assembly accuracy of the parts can be guaranteed. At this point, parts are fully interchangeable. [0004] If the dimensional and geometric tolerances of the design are small, the possibility of the pa...
