Embodiment Construction

[0011] The present invention will be further described below in conjunction with accompanying drawing:

[0012] As shown in the accompanying drawings, the large-tonnage large-diameter high-precision cylinder processing method utilizes a large-tonnage large-diameter high-precision cylinder processing machine tool for processing. The large tonnage is more than 50 tons, the maximum diameter is more than 5 meters, and the height The precision is within 0.02mm. The large-tonnage, large-diameter, and high-precision cylindrical processing machine tool includes a tool rest bed 6 and a workpiece bed 9 arranged side by side on the foundation, one end of the workpiece bed is connected to the base of the headstock 1, and a faceplate is connected to the main shaft of the headstock 1 2. The faceplate 2 is connected with a universal joint 3, and the other end of the universal joint 3 is connected with the workpiece to be processed. The workpiece bed 6 at the other end of the workpiece is pro...

Abstract

The invention discloses a method for processing a large-tonnage large-diameter high-precision cylinder which is characterized by comprising the following steps: 1) connecting static pressure centre rests on a workpiece bed body; 2) adjusting the center height of a plurality of static pressure centre rests; 3) placing workpiece on the static pressure centre rest and ajusting the centre of the workpiece; 4) utilizing a cardan joint (3) to flexibly connecting the workpiece with a faceplate (2); 5) respectively arranging a dial indicator and an oiling film below the workpiece and near the static pressure centre rests, and detecting the thickness of the oiling film; 6) manually adjusting the thickness of the oiling film; 7) detecting whether the thickness of the oiling film changes after the workpiece idles for more than four hours; and 8) locking main supports of the static pressure centre rests. The processing method disclosed by the invention has the characteristics of high efficiency and guaranteed quality.

Description

technical field [0001] The invention relates to a mechanical processing method, in particular to a large-tonnage large-diameter high-precision cylinder processing method. Background technique [0002] In the field of mechanical processing, for cylindrical workpieces with a weight of more than 50 tons, a diameter of more than 5 meters, and a tolerance of less than 0.02 mm, the existing processing methods have problems of low efficiency and difficult quality assurance, which is not conducive to popularization and application. Contents of the invention [0003] The invention provides a large-tonnage large-diameter high-precision cylinder processing method. The large-tonnage, large-diameter, and high-precision cylinder processing method has the characteristics of high efficiency and guaranteed quality. [0004] The technical solution of the present invention is: the large-tonnage large-diameter high-precision cylinder processing method utilizes a large-tonnage large-diameter ...
