Problems solved by technology

[0007] 1. Conventional boring needs to make multiple process holes, and the efficiency is low;
[0008] 2. When adjusting the fine-tuning device of the boring tool, the scale of the boring tool cannot be adjusted to the theoretical value accurately due to human factors and tool precision factors. Repeated boring and adjustment each time will take a lot of time and the efficiency is low;
[0009] 3. Conventional boring does not evenly distribute the margin of the boring, so there is a certain error between the actual measured size and the theoretical adjustment size of each boring, and it is easy to appear that the diameter of the process hole is qualified and the diameter of the part hole is unqualified during fine boring

Embodiment 1

[0031] Such as figure 1 , a boring processing method, the steps of which are:

[0032] A. Leave a margin outside the machined part to try boring a process hole with the same diameter as the hole of the part to be machined;

[0033] B. Measure the size X after the trial boring of the process hole in step A, and keep the current scale value Y of the boring tool;

[0034] C. Measure the trial boring process hole, and divide the machining allowance into Z parts after measurement, Z≥2;

[0035] D. According to the error value between Y converted into aperture and size X, compensate the error into X, convert it into the corresponding boring tool scale, and fine-tune the boring tool;

[0036] E. According to the machining allowance measured in step C, the part hole is evenly divided into Z times. After the first machining, measure the size P of the part hole at this time, and keep the current boring tool scale value R, and calculate the remaining allowance through P W, the seconda...

Abstract

The invention relates to the boring machining field and in particular relates to a boring machining method. The boring machining method comprises the following steps: A, remaining allowance outside a processing part for trial boring of a process hole having the same diameter as a part hole to be machined; B, measuring a dimension X of the process hole after trial boring in the step A and retaining a current scale value Y of a boring cutter; C, measuring the part hole to be maintained and equally dividing the allowance for machining into Z portions after measurement, wherein Z is greater than or equal to 2; D, according to an error value between a hole diameter converted from Y and the dimension X, performing compensation on X with the error, converting the compensated X into a corresponding scale of the boring cutter and fine adjusting the boring cutter; and E, boring the part hole in equally divided Z steps according to the allowance for machining measured in the step C. The purpose of the invention aims at providing a boring machining method for improving the machining efficiency and increasing the yield of parts.

Description

technical field [0001] The invention relates to the field of boring processing, in particular to a boring processing method. Background technique [0002] Introduction to conventional boring steps: [0003] 1. Install the tool and adjust the approximate range of the boring tool; [0004] 2. Drill, expand, and test bore multiple process holes with the same diameter as the part outside the part, repeatedly adjust and test bore multiple process holes until the process hole diameter is qualified; [0005] 3. Fine boring holes on parts; [0006] Conventional boring defects: [0007] 1. Conventional boring needs to make multiple process holes, and the efficiency is low; [0008] 2. When adjusting the fine-tuning device of the boring tool, the scale of the boring tool cannot be adjusted to the theoretical value accurately due to human factors and tool precision factors. Repeated boring and adjustment each time will take a lot of time and the efficiency is low; [0009] 3. C...
