Description
Technical field
The present invention relates to engine cam mounting technique field, especially relate to a kind of camshaft installation method and frock is installed.
Background technology
Camshaft is the important spare part on the engine, and the correct installation of camshaft is directly connected to the performance of engine valve actuating mechanism.General way is earlier camshaft directly to be placed on the cylinder cap at present, by bolt camshaft frame is fixed on the cylinder cap again, finishes installing and fixing of camshaft.This general mounting means only is applicable to that camshaft directly passes through the situation of cylinder cap, frame fixation, because structural design and arrangement requirement, when needs carry out packing to camshaft and framework, then general mounting means can not satisfy this requirement, be necessary to invent an independent frock like this and fix camshaft, the assembling of auxiliary cam axle.
Summary of the invention
The purpose of this invention is to provide a kind of camshaft installation method, camshaft is worked as in solution and framework needs under the fixing situation of packing, by the problem of frock stationary cam axle and framework.To satisfy conveniently matching requirements.
Further, the object of the invention provides a kind of installation frock of camshaft installation method.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of installation method of camshaft may further comprise the steps:
Step 1: camshaft frame is inverted on workbench, admission cam shaft and exhaust cam shaft after cleaning are placed on the camshaft frame, rotate admission cam shaft and exhaust cam shaft and do not have clamping stagnation;
Step 2: camshaft-bearing cap is fixed by bolts to the camshaft frame front end, rotates admission cam shaft and exhaust cam shaft again, no clamping stagnation, the actuating cam axle guarantees the thrust gap;
Step 3: camshaft erector dress is placed on the camshaft frame, the second protrusion key that camshaft is installed on protrusion key of first on the frock forearm and the postbrachium is embedded into respectively in exhaust and the admission cam shaft rear end groove, and with the frock bolt camshaft is installed frock and be fixed on the camshaft frame, form the packing assembly;
Step 4: above-mentioned packing assembly is turned over turnback, be placed on the cylinder cap, camshaft frame is fixed on the cylinder cap, pull down camshaft frock is installed, final complete admission cam shaft and exhaust cam shaft fixing with bolt.
Further, described step 1 also comprises checking whether camshaft and camshaft frame OHC frame bearing hole totally do not have burr, and adds lubricating oil at the dead eye place.
Adopt a kind of camshaft of above-mentioned camshaft installation method that frock is installed, it is characterized in that: integral body can be divided into three parts, and it comprises forearm, postbrachium, linking arm; Forearm be provided with the exhaust cam shaft rear end on groove suitable first protrude key; Postbrachium be provided with the admission cam shaft rear end on groove suitable second protrude key, and be provided with and be fixed on bolt hole on the framework frock is installed.
For adaptive framework, end face is adaptive on described linking arm and the framework, and described postbrachium and back-end framework face are adaptive.
For adaptive camshaft rear end, the described first protrusion key and second protrudes key and is shaped as cuboid.Described forearm and postbrachium are parallel to each other.
Beneficial effect of the present invention: owing to adopt frock stationary cam axle and framework are installed, can be realized the packing of camshaft.Method step rationally, safely, fast.And because camshaft is installed frock, its integral body can be divided into three parts, comprise forearm, postbrachium, linking arm, be used for frock is fixed on bolt hole on the framework having on the postbrachium, forearm be provided with exhaust cam shaft on groove suitable first protrude key, postbrachium be provided with admission cam shaft on groove suitable second protrude key, when camshaft needs under the fixing situation of packing, make it put into capable packing to satisfy conveniently assembling process by the camshaft erector.
Below with reference to drawings and Examples, the present invention is carried out comparatively detailed explanation.
Description of drawings
