Abstract

The invention provides a rounding device, and relates to the technical field of diesel engine part maintenance. The rounding device solves the problem that a cylinder liner needs to be lifted from an engine body of a diesel engine and taken to a workshop to repair with the existing repair method. The rounding device comprises a cross-shaped support used for supporting, a shaft sleeve is arranged on the center of the cross-shaped support, the shaft sleeve is connected with a connecting shaft of a motor, and the motor is provided with a handle. The cross-shaped support comprises four branch supports, the branch supports are movably connected with an upper dam board and a lower dam board and wrap movable arms, the branch supports are connected with the movable arms through fixed bolts in a screwing mode, the upper dam board is connected with the upper end of the support through tightening bolts in a threaded mode, the lower dam board is connected with the lower end of the support through tightening bolts in a threaded mode, and grinding heads and guide heads are alternately arranged at the end portions of the movable arms. The rounding device has the advantages that the cylinder liner can be repaired on site, repair time is shortened, and repair cost is reduced.

Description

technical field [0001] The invention relates to the technical field of maintenance of diesel engine parts, in particular to a rounding device used for on-site grinding of cylinder liners of marine diesel engines. Background technique [0002] At present, during the repair process of diesel engine cylinder liners on many domestic ships, the problem of ellipticity of the cylinder liner will be encountered. The ellipse is mainly caused by the movement of the piston in the cylinder liner, including normal wear and abnormal wear. If its wear is still within the limit range of use, of course it must be repaired, because the cost of the cylinder liner is relatively high, especially for foreign diesel engines, the price is very expensive when using foreign cylinder liners. The current repair method is basically to hang the cylinder liner from the body of the diesel engine, and then take it to the workshop for repair, such as turning on a lathe, boring on a boring machine, etc. Altho...
