【正文】 prepare workstation a body assemblies and outfit floor skeleton weldinginstallation skinned leftright side cover drawing, welding skinned assembly welding passenger area is welded nickelbased sealed cover, the driving area lateral seal welded lateral warehouse door, round skinned body and installation of arc three chassis buckle close luggage storehouse skeleton welding luggage storehouse seal welded weld burnish, make gum part of chassis a installation nap, especially by electric car translation into coating workshop. C. body close pack adopts hydraulic drive stereo fold device. Body and outfit craft is body manufacturing process the essential process, is weldinginstallation production line, the first step in the process of its close outfit effect directly affect the quality of the vehicle. Control and outfit craft is control vehicle body manufacturing quality key steps. Therefore, using this equipment can improve stability of quality body manufacturing, improve the production efficiency, and achieving specialization, largescale production. Fold the positioning device 3d clamping device, easy adjustable varieties bus production requirement. D. left/right tension adopt fission style side skinned skinned hydraulic tensile equipment. Adopt open decorate, namely tensile institution in the body, the front/rear end pletely opened central, can make workers under the condition of the disabled, guarantee body side welding operation smoothness, also facilitate decorate welding tools. It is applicable for various models, all kinds of process conditions for the production, realizing resistive spot welding skinned side have created favorable conditions (resistive welding process domestic immature). E. the cover by skinned assembly welding low work processes. Due to the higher, homework bus body position is relatively high, operation convenience, product quality assurance, production line not big workload, so will the high weldinginstallation skinned moved ground weldinginstallation homework, the top finish rolling welding equipment skinned resistance top new welding skinned low. This device can cover three zhang molded to the rigging, through the positioning, stretching and resistance, forming a top rolling welding skinned assembly. The welding deformation small, surface smooth, not leak, productivity is high, can pletely solve the actual problem cover leak. Due to the top of the difficult skinned assembly, its operation transport venue layout in production line, convenient use. Flanks F. skinned assembly and ceiling cover can be used in the welding skeleton assembly process performance is good, welding quality high automatic welding low homework production mode. G. using body assemblies and three chassis in welding line fits buckled in the process, realize rapid and stable transportation mode, solve body assemblies in longdistance conveying process distortion problem, the conjunction of quality guarantee plete car, avoid fits the car appear more after the preface secondary damage. H. line close to the next station install location button and using cranes and body workstation place and vehicle sling auxiliary equipment, realize the hoisting the vehicle. I. line fits the body each station buckle before using welding specialized technique revolving cars, buckles and body for coating workshop when gm39。s redtipped car, flexible and convenient process flow. J. production line adopts full chamber ventilation dust removal device. For production line the use of CO2 welders, production assignments produce a lot of smoke, in order to guarantee the healthy and civilized production workers, requires production to improve their space clean work environment, adopt the whole room ventilation dust removal device. 230 personnel structure equipped with the influence of in the manufacturing Staff is a enterprise most important production resources and enterprise can get more by recruitment, training excellent employees, in order to gain the powerful petitive advantage, who keep side39。s outstanding talents, who had won power for sustainable development of the enterprise. In the process of bus production anization, staff work quality, technical skills, structure equipped with, to the production process and new technology, new technology, the implementation has more influence. A. for buses are concerned, advanced parts manufacturing technology, the vehicle manufacturing technology, advanced technology and equipment, the consummation technical process all must depend on the excellent staff to achieve high quality, is the production of one of the bus based. Therefore, in view of the manufacturing mode formed, according to process flow reasonably allocating personnel quantity, resource, meet the need of the production DingGang balanced, production, ensure the production beats. B. personnel structure equipped with directly affect the manufacturing process each link, each key processes, restricted set of senior skilled worker details parts, forming a plete this work quality control of process chain, realize the manufacturing process and process quality control and improve. C. recruitment highlevel technical workers and distribution in key process with low and high technical training for original employees specialized production, realizing process way. Highlevel technical workers should be accounted for 40% of the total number to ensure production process does not appear quality problem, ensures that each sequence quality to achieve the design quality requirements. D. coach weldinginstallation production line of automation degree, low labor strength, mainly by manual skill homework, key procedure match with advanced technology and equipment. When the researchers assigned production operators should be arranged use have certain skills male
