Embodiment Construction

[0041] The present invention will be further described below in conjunction with embodiment, but should not limit protection scope of the present invention with this.

[0042] see first figure 1 , figure 2 with Figure 4 The processing method of the high-precision coaxial hole of the ultra-long coaxial hole system workpiece of the present invention comprises the following specific steps:

[0043] ①Installing the workpieces of the ultra-long coaxial hole system to be processed with the spacing of most bearing holes greater than the length of the machine tool attachment along the forward direction of the boring and milling machine, that is, the 0° direction;

[0044] ②In the direction of 0°, first extend the machine tool attachment 3 into the interval L2 of the bearing hole greater than the length L1 of the machine tool attachment, and rough machine the bearing holes 21, 22, 23...28 one by one;

[0045] ③After turning the machine tool attachment 3 to 180°, rough machining th...

Abstract

A method for machining high-accuracy coaxial holes on the workpiece with ultra-long coaxial holes features that after the bearing holes are sequentially and accurately machined, the accessory of machine-tool is turned over by 180 deg. The accurately machined bearing hole is aligned with the coordinate of axle center of said accessory for accurately machining other bearing holes. The position error of finished bearing hole is less than 0.01 mm.

Description

technical field [0001] The invention relates to mechanical processing, in particular to a processing method for high-precision coaxial holes of superlong coaxial hole system workpieces. Background technique [0002] When a large CNC gantry boring and milling machine is used to process the coaxial hole system of large parts, due to the limitation of conditions, some of the holes are limited by the size and length of the machine tool accessories and tool holders, and the machine tool accessories cannot complete all the coaxial hole system workpieces in the same direction. Machining of coaxial holes. [0003] Taking the frame, one of the main parts of a large low-speed marine diesel engine, as an example, the main parts of its structure are super-long coaxial holes with a length of 8 to 10 meters. According to the number of cylinders, the hole system is composed of bearing holes of multi-stage bearings with unequal intervals, such as figure 1 shown. The length of each hole i...
