Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the embodiments: the present invention proposes a tool and method for processing comb lines capable of absorbing carbon deposits on the inner wall of the cylinder liner. The comb line processed by this method can effectively absorb the carbon deposits in the cylinder liner, making the carbon deposits gather in the non-working area of ​​the cylinder liner, preventing the carbon deposits from slipping to the working area of ​​the piston and cylinder liner, and affecting the normal operation of the cylinder .

Abstract

The invention discloses a tool and method for machining comb lines on an inner wall of a cylinder liner, and belongs to the field of machining. The tool for machining the comb lines on the inner wall of the cylinder liner comprises a knife holder and a comb line knife. The comb line knife comprises a hilt, a crossbeam, auxiliary hilts and rollers, a U-shaped groove is formed in each auxiliary hilt, and directions of openings of the U-shaped grooves in the two auxiliary hilts are opposite to each other. Each U-shaped groove is connected with the corresponding roller through a corresponding hinge pin, and outer circle surfaces of the two rollers are higher than the tops of the corresponding U-shaped grooves. A threaded rod is mounted in the middle of each of the two auxiliary hilts, and each auxiliary hilt is connected with the corresponding threaded rod through a corresponding fixing device. In addition, the method for machining the comb lines on the inner wall of the cylinder liner comprises the following steps: step A, mounting a clamp and a knife; step B, adjusting the clamp and the knife; step C, rolling the comb lines; step D, removing burrs; and step E, cleaning and polishing the comb lines. The special tool is used for machining the comb lines, damage to a machine tool is small, and machining steps are simple; and the machined cylinder liner can adsorb carbon deposits and is high in strength.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a tool and a method for processing comb wires on the inner wall of a cylinder liner. Background technique [0002] The cylinder liner is an important part of the engine. The cylinder liner, piston and cylinder head together form the combustion chamber of the engine. In the combustion chamber, due to insufficient oxygen supply, the fuel and the lubricating oil entering the combustion chamber cannot be completely combusted to produce soot and tar particles. After they are mixed with the lubricating oil, they are continuously oxidized and form carbon deposits under the continuous action of high temperature. Especially in diesel engines, due to the complex composition of diesel and the compression ignition working principle of diesel engines, the formation of carbon deposits is almost inevitable. If the carbon deposits are not cleaned in time, excessive carbon deposits will accum...
