Abstract
The invention discloses a ventilation cover plate connecting method for an automobile engine cylinder cover. The method is characterized by comprising the following steps of: a, manufacturing an engine cylinder cover which is provided with a plurality of convex round platforms which are uniformly distributed on the edge of an inner side chamber and the top of a boss inside the chamber, and ventilation cover plates which correspond to the convex round platforms and are provided with through holes in an integral molding way; b, dispensing at positions on the engine cylinder cover which are contacted with the ventilation cover plates; c, arranging the ventilation cover plates, making the round platforms pass out of corresponding through holes for serving as rivet heads, coating a layer of butter on the rivet heads, and arranging a workpiece on a rotary riveting machine clamp; d, arranging a maximum downward moving distance of a riveting column of a riveting machine; and e, rotating rivets within 10 minutes after dispensing, wherein the diameters of the rivet heads which are flattened and molded after rotating rivet are required to be greater than 7.2 millimeters. The method has the advantages of higher easiness for processing, lower cost, better sealing effect and the like.
Description
technical field [0001] The invention relates to an automobile engine cylinder head cover, in particular to a method for connecting a ventilation cover plate of an automobile engine cylinder head cover. [0002] Background technique [0003] On the cylinder head cover of the automobile engine, a vent cover needs to be installed. The vent cover is inside the cylinder cover, so that a closed space is formed between the vent cover and the cylinder cover. This closed space is used for engine operation. The oil and gas produced are separated. [0004] In the prior art, the connection method of the ventilation cover plate of the automobile engine cylinder head cover is as follows, including the engine cylinder cover and the cover plate fixed on the edge of the inner chamber of the engine cylinder head cover, the edge of the inner chamber of the engine cylinder head cover and the cavity A number of threaded holes are distributed on the edge of the position where the inner boss is ...
