Portable boring machine for servicing engines

Abstract

The invention relates to a portable hole drilling machine for repairing an engine. The hole drilling machine comprises a machine frame, a driving motor (1) and a rotating shaft (2), wherein the rotating shaft (2) can be rotationally installed in the machine frame in a vertical direction, and the driving motor (1) is used for driving the rotating shaft (2) by a transmission mechanism. The hole drilling machine is characterized in that the lower part of the rotating shaft (2) is provided with a blade (4) which is used for drilling holes, a positioning mechanism (5) which can be fixed with an engine is installed on the rotating shaft (2) below the blade (4), and the upper part of the machine frame is provided with a lifting mechanism (7) which can enable the rotating shaft (2) to move from up to down. The hole drilling machine has the advantages that the blade and the positioning mechanism are arranged at the lower end of the rotating shaft, the lifting mechanism and the positioning mechanism are used for positioning during working, the rotating shaft is driven by the driving motor to rotate so as to drive the blade to drill the holes in the inner wall of the engine, and therefore the purpose of process is achieved. The hole drilling machine also has the advantages of simple and reasonable structure, easiness in operation, convenience in carrying, good processing effect, time saving and labor saving. Besides, the automatic hole drilling for the inner wall of the engine can be realized.

Description

technical field [0001] The invention relates to a hollowing out device, in particular to a portable boring machine for repairing an engine and repairing the corrosion of the sealing water part of the cylinder liner of the engine body. Background technique [0002] During the long-term use of the engine, the cooling part inside will corrode under the washing of cooling water, especially the engine body will produce corrosion depressions at the part of the cylinder liner sealing water ring, and the sealing of this part will cause water leakage and other serious problems. As a result, artificial glue is generally used for repairing, but its service life is short and the repair frequency is high, which greatly increases the maintenance cost of diesel engines and also affects the running time. [0003] Existing boring machines, such as the Chinese invention patent "a kind of boring machine" whose patent number is CN201010193850. Worm gear, the main shaft meshed with the worm gea...

AI Technical Summary

Problems solved by technology

This structure can bore holes with complex structures and small spaces. Corrosion and depressions in the water sealing parts of the cylinder liners of the engine body must be dealt with in time, otherwise it will affect the service life of the entire engine. Therefore, it is necessary to develop a new type of maintenance The boring machine of the engine is specially used for boring the sealing water part of the cylinder liner of the engine body
