Embodiment Construction

[0013] A method for repairing a camshaft hole of a diesel engine, comprising a micro-grinding repair process and a regrinding deformation repairing process, the micro-grinding repairing process mainly adopts an electric brush plating process or a welding process, and the regrinding deformation repairing process includes the following steps: fixing→boring→boring Hole → sleeve → sleeve.

[0014] The micro-grinding repair process is applied to the case where the wear of the camshaft hole is less, and the wear of the hole diameter is less than or equal to 0.5mm. The brush plating or welding process is used, combined with the fitter's manual repair.

[0015] The regrinding deformation maintenance process is applied to the situation where the cam hole is severely deformed or worn, and the wear of the hole diameter is greater than 0.5mm, and the flow-type maintenance process is adopted.

[0016] The fixing steps include: firstly adjust the position of the camshaft hole of the machine...

Abstract

The invention relates to the technical field of a diesel locomotive engine, and particularly relates to a method for repairing a cam axle hole of a diesel engine. The method comprises a micro-grinding repair technology and a regrinding deformation repair technology. The micro-grinding repair technology mainly adopts an electric brush plating technology or a welding technology; the regrinding deformation repair technology comprises the following steps of fixing, aligning, boring, sleeve preparing and sleeve packing. By adopting the repair technology method, the coaxiality of the cam axle hole of the machine body and maintenance quality of the aperture can be obviously improved, and an operation fault of a diesel engine is reduced. As for the machine body with severely deformed cam axle hole, by adopting the repair technology method, the scrapping of the machine body can be avoided; and the service life is prolonged, and obvious economic benefits are obvious.

Description

technical field [0001] The invention relates to the technical field of internal combustion locomotive engines, in particular to a method for repairing a camshaft hole of a diesel engine. Background technique [0002] Abrasion of the camshaft hole of the diesel engine body is a common form of body failure. Due to the wear of the camshaft hole, the coaxiality of the camshaft hole of the body is out of tolerance, the hole diameter becomes larger, and the body cannot be used normally. Sometimes due to the failure of the diesel engine, such as the burning of the camshaft bush of the diesel engine, the cam hole of the body is seriously deformed, and the camshaft hole of the body cannot be repaired and is scrapped. Contents of the invention [0003] In order to overcome the problem that the camshaft hole of the existing diesel engine is easy to wear and cause the engine body to be scrapped, the invention provides a method for repairing the camshaft hole of the diesel engine.
