Abstract

The invention discloses a crankshaft front oil seal base and an assembling method. The assembling method includes the following steps that A, a cylinder body is placed on a tray of an assembling line,one end of an auxiliary positioning block is installed on the cylinder body through a bolt, and the auxiliary positioning block is provided with an arc-shaped side opening corresponding to an arc-shaped opening of a positioning table part of a crankshaft front oil seal base body; and B, then the crankshaft front oil seal base body is placed on the cylinder body, a positioning face of the crankshaft front oil seal base body is made to be connected with the upper end face of the tray in an abutting manner, the work face of the crankshaft front oil seal base body is connected with the front endface of the cylinder body in an abutting manner, the side face of the positioning table part and the side face of the auxiliary positioning block are made to be connected in an abutting manner, a round positioning hole is defined by the arc-shaped opening and the arc-shaped side opening, and then a positioning column on the tray can be used for performing positioning and assembling on the crankshaft front oil seal base body through the round positioning hole. Compared with the prior art, the crankshaft front oil seal base can solve the problem that during assembling of an existing crankshaft front oil seal base, the existing crankshaft front oil seal base can easily intervene with peripheral parts.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a crankshaft front oil seal seat for automobiles and an assembly method thereof. Background technique [0002] The front oil seal seat of the crankshaft is an important part of the automobile engine. In order to meet the requirements of fixing the engine on the assembly line, a positioning hole is usually provided on the front oil seal seat of the crankshaft for the positioning of the engine on the assembly line; the fixing hole on the front oil seal seat of the crankshaft is only It works when assembled on the assembly line. When the engine is off the assembly line, the fixing hole loses its meaning; but when the front oil seal seat of the crankshaft with this structure is assembled on the whole vehicle, the fixing hole is easy to interfere with the surrounding parts, and there are Hidden dangers affecting assembly quality. Contents of the invention [0003] ...
