Problems solved by technology

[0002] The function of the oil pump is to increase the oil to a certain pressure and then forcefully send it to the moving surface of the engine parts. When the engine oil pump is manually installed, the concentricity between the center hole of the oil pump and the center of the crankshaft is difficult to ensure. It is easy to cause oil leakage of the curved front oil seal installed later

Abstract

The invention relates to a crankshaft front end oil seal tool capable of precisely positioning and pressing. The crankshaft front end oil seal tool capable of precisely positioning and pressing comprises a machine oil pump positioning sleeve, an oil seal positioning sleeve and an oil seal pressure head, wherein the machine oil pump positioning sleeve sleeves the crankshaft front end of an engine crankshaft; the crankshaft front end passes through a central hole of the oil pump; the machine oil pump positioning sleeve passes through the central hole of a machine oil pump and sleeves the crankshaft front end; an oil seal slot is formed in the central hole; a crankshaft end front oil seal is mounted in the oil seal slot; the crankshaft front end oil seal is positioned by the oil seal positioning sleeve; the crankshaft front end oil seal is mounted through the oil seal pressure head; the crankshaft front end is a step shaft formed by an inner side shaft and an outer side shaft; and the diameter of the inner side shaft is greater than that of the outer side shaft. Generally, the crankshaft front end oil seal tool is reasonable in design, and has the advantages of being simple in structure, convenient in operation and capable of precisely positioning.

Description

technical field [0001] The invention belongs to the technical field of engine oil seal equipment, and in particular relates to an oil seal tool for precise positioning and press-fitting before bending. Background technique [0002] The function of the oil pump is to increase the oil to a certain pressure and then forcefully send it to the moving surface of the engine parts. When the engine oil pump is manually installed, the concentricity between the center hole of the oil pump and the center of the crankshaft is difficult to ensure. It is easy to cause oil leakage in the curved front oil seal installed later. Contents of the invention [0003] The object of the present invention is to provide a simple structure, convenient operation, which can accurately position the oil seal tool before buckling. [0004] The purpose of the present invention is achieved in the following way: a precise positioning and press-fitting front oil seal tooling, which is composed of an oil pump...
