Abstract
The utility model discloses integrated motor cam shaft covers, which are integrally connected by an upper connection plate and a lower connection plate; each cam shaft cover is provided with a fastening bolt hole in the upper and lower parts respectively; a cotter pin is assembled in the bolt holes in lower parts of the first cam shaft cover, the third cam shaft cover and the fifth cam shaft cover respectively; the cotter pins are arranged in the left, middle and right positions of the integrated cam shaft covers to realize precise positioning; and each cam shaft cover is designed with the separate fastening bolt hole. The integrated cam shaft covers and cylinder covers are positioned and fastened by bolts to ensure the precise reset of each cam shaft cover and each cylinder cover during secondary disassembling. Compared with an independent cam shaft cover structure, the integrated cam shaft covers have the advantages of integrating the cam shaft covers with a rocker base, adopting the cotter pins for precise positioning, improving the work efficiency and the assembly precision in the assembly procedure, and reducing error probability of assembly and the fault rate caused by part deformation.
Description
Technical field
The utility model belongs to engine component, is specifically related to a kind of engine camshaft cover.
Background technique
Along with the develop rapidly of motor new technology, now increasing motor adopts the overhead camshaft design, and the application of overhead camshaft arrangement is very extensive on high speed engine especially.The rocking arm shaft-cup of general overhead camshaft engine is mostly stand-alone configuration, and the upper numerical coding of casting thereon when machining cam axis hole, rocker shaft hole, need to use bolton on cylinder cap these shaft-cups to show difference.When assembling camshaft, pitman arm shaft, first shaft-cup is taken off, assemble after complete and by coding is corresponding one by one, assemble fasteningly again, can not put upside down.Therefore the operator must be very careful, does comparatively time-consuming.Because the coaxality requirement on machining accuracy in camshaft, pitman arm shaft two holes is higher, adds and need position with bolt man-hour simultaneously.Even like this, after processing, because of the secondary dismounting, cause the situations such as shaft-cup distortion, axis hole ellipse also to happen occasionally.Proposition of the present utility model, can make this difficult problem be resolved.
Summary of the invention
The purpose of this utility model is, a kind of combined camshaft cover is provided, the rate of breakdown that adopts perforate finger setting mode to reduce the loading error probability and cause because of part deformation.
Design proposal of the present utility model is: camshaft cover is connected as a single entity by upper junction plate and lower connecting plate, and each camshaft cover is equipped with fastening bolt holes up and down.Bolt hole below first, the 3rd and the 5th camshaft cover is equipped with cotter pin.Cotter pin is arranged on the San Ge position, left center right of combined camshaft cover and realizes accurately location, and on each camshaft cover, is designed with independent fastening bolt holes.By combined camshaft cover and cylinder cap location, and with bolt, carry out fastening, to guarantee precisely resetting of when the secondary dismounting assembling camshaft cover and each cylinder cap position.
The utility model characteristics are, combined camshaft cover structure is compared with independent cam shaft-cup structure, camshaft cover and pitman arm shaft base are made of one structure, adopt cotter pin accurately to locate, working efficiency and the assembly precision of assembly process have been improved simultaneously, the rate of breakdown that has reduced the loading error probability and caused because of part deformation.

Embodiment
Below in conjunction with accompanying drawing and by specific embodiment, structure of the present utility model is further described.
Motor combined camshaft cover, its structure is: camshaft cover 1 is connected as a single entity by upper junction plate 2 and lower connecting plate 3, and each camshaft cover is equipped with fastening bolt holes 4 up and down.Bolt hole below first, the 3rd and the 5th camshaft cover is equipped with cotter pin 5.Upper junction plate is processed with circular hole 7 and ellipse breach 6 in order to loss of weight.Camshaft cover below (and between pitman arm shaft base) is oil leab, and in engine operation, lubricant oil enters the lubricant reservoir in pitman arm shaft by this oil duct, meets the lubricated and hydraulic tappet tensioning function of inlet and exhaust valve rocking arm.The combined camshaft cover is selected aluminium, and one-step die casting.
After being fastened on combined pitman arm shaft cover bolt on cylinder cap, camshaft hole and rocker shaft hole are processed, so just can be met the requirement on machining accuracy in camshaft, pitman arm shaft two holes, prevent from processing the rear circular hole distortion that causes because of dismounting camshaft cover one by one.
