Description

The full-automatic assembly technology of engine rocker valve and production line

Technical field

The present invention relates to a kind of technique for engine valve rocker arm assembly and realize the production line of the process route, Belong to engine valve rocker arm mounting technology field.

Background technique

The valve rocker of automobile engine as shown in Figure 1, include intake rocker 03, rocker arm shaft 04 and exhaust rocker arm 06, into Gas rocker arm 03 and exhaust rocker arm 06 are separately mounted to the left and right sides of rocker arm shaft 04, and intake rocker 03 passes through left retaining ring 02 and left card Spring 01 realizes axially position, and exhaust rocker arm 06 is realized axially position by right retaining ring 07 and right circlip 08, had on rocker arm shaft 04 Rocker shaft bed 05.One end of intake rocker 03 and exhaust rocker arm 06 is respectively mounted adjusting screw 09, has in adjusting screw 09 locking Nut 010, the other end install idler wheel 012 by rolling pin 011.

Currently, comprehensive automation is still not implemented in automobile engine in terms of the assembly of rocker arm.Intake rocker and exhaust are shaken Arm is assembled to rocker arm shaft, and is all made of and is accomplished manually in the work of rocker arm shaft both ends installation circlip retaining ring, and assembly efficiency is low, precision Difference；Retaining ring and circlip are independent self-feeding, can not achieve retaining ring and circlip self-feeding simultaneously, so that on retaining ring and circlip Expect asynchronous, cannot convey simultaneously in place, this reduces assembly efficiencies；The assembling of adjusting screw and stop nut is all made of people Work is completed, and be can not achieve adjusting screw and stop nut self-feeding and adjusting screw while being screwed into automobile rocker and locking spiral shell Mother, this reduces assembly efficiencies；The assembling of idler wheel and rolling pin, which is all made of, to be accomplished manually, and can not achieve rocker arm rolling pin automatically simultaneously Automobile rocker and rocker-arm roller are penetrated, assembly efficiency is low, low precision.

With the rapid development of the automotive industry and the requirement to intelligence manufacture, during vehicle key component assembling The up-to-date informations such as cloud computing, big data, Internet of Things Numeric Control Technology and production management are melted in the research of intelligent numerical control system It closes, while realizing that robot replaces manual operation, realizes that (manufacturing enterprise's production process executes by erecting yard and enterprise MES System) effective information transmission, for each enterprise realize factory's digital management development establish basis, to the dress of automobile engine New requirements at the higher level are proposed with manufacturing method and critical equipment.

1. Automobile Enterprises are the market demand that reply is constantly promoted, in the case where not expanding production equipment investment, more Be to be promoted the beat of engine general assembly line to highest-capacity, by original 3 by improving existing capital equipment production efficiency Minute/platform is promoted to 2 minutes/platform, also has higher requirement to the assembly demand of corresponding components；

2. the assembling manufacturing of automobile engine is from traditional semi-automatic assembly gradually to process standardization, height intelligence Change, height web development, production plan, the market demand, information after sale are directly networked, and propose information interconnection to manufacturing equipment The new demand of intercommunication proposes new requirement to the assembly information for the engine key components and parts for still using hand assembled；

3. Automobile Enterprises require the volume increase not person of increasing, the efficient production of new vehicle should be met, and not can increase operator Member, and also to reduce equipment operator's quantity；

4. Automobile Enterprises propose the new demand of energy-saving and emission-reduction to critical equipment, the production production capacity of engine should be promoted, The low investment for realizing the energy again has completely new concept to the assembly energy conservation and environmental protection aspect of corresponding engine；

5. newly-built engine production line and the old production line of tradition, to constantly reducing land occupation face in the space layout of workshop Product, control production line length, promotes the output value of unit area, it is desirable that the packing layout of each components of engine meets logistics delivery While, diminution occupied area as far as possible；
