Description

Technical Field

[0001] The utility model mainly relates to the technical field related to the installation of a camshaft cover of a cylinder head, in particular to a camshaft cover installation roller track. Background Art

[0002] For engine cylinder head, such as Figure 1 As shown, multiple camshaft covers need to be installed on the cylinder head. The installation process of the camshaft cover is generally to first place the camshaft cover on the corresponding position of the cylinder head through the installation template, and then tighten the corresponding screws.

[0003] In the prior art, the roller conveyor used for tightening the camshaft cover is generally used at the tightening station, that is, the staff installs the camshaft cover on the cylinder head in advance, and then pre-tightens the screws before placing it on the roller conveyor.
