Description
Technical Field
The invention relates to the technical field of automobile body transportation, in particular to a coating production trolley rear supporting device and a coating production trolley.
Background
At present, mixed flow production of multiple vehicle types becomes a main production mode for production and manufacturing of automobile main engine plants. The white automobile body of the automobile is sent to coating after being welded, assembled and adjusted, the white automobile body is transported by a lifting appliance in the pretreatment electrophoresis, the subsequent production process of a coating workshop is completed by transporting the white automobile body by a trolley after the electrophoresis is transferred until the white automobile body is transferred to a general assembly workshop, and the trolley is an important tool for coating and transporting the white automobile body.
Some factories can produce mixed flow in a collinear way in coating workshops, and the models can be as many as 10. The current platform truck that uses mainly supports the white automobile body through totally 4 supports around, and left and right front support is the locating pin, and on the floor locating hole fell into the locating pin brace table before the white automobile body, the locating pin can support it, and the size and the structure of platform truck locating pin have all been considered at the design stage to all motorcycle type locating holes, therefore the platform truck left and right front support need not change just can all motorcycle types of adaptation.
However, the supporting positions of the left rear support and the right rear support are rear longitudinal beams of a body-in-white, 10 models of vehicle platforms produced by mixed flow are different, the structures of the rear longitudinal beams are different, and the contact positions of the rear longitudinal beams and the rear supports of the trolley are also different.
And bearing structure is single behind current platform truck, only can come the new motorcycle type of adaptation through increasing back supporting quantity, and before putting into production the new motorcycle type at every turn, all will carry out the suitability and reform transform, makes the platform truck can the new motorcycle type of adaptation, can adapt to all existing production motorcycle types simultaneously again.
When the existing trolley rear support cannot meet the support requirement of a newly-invested trolley type, the existing rear support is required to be modified, the number of the rear support is generally increased in a modification mode, namely the original rear support supports the original trolley type, the new rear support supports the newly-invested trolley type, and the number of the rear support of the trolley is increased along with the increasing of the number of the new trolley types.
With the increasing number of the increased trolley rear supports, the trolley structure is more and more complex, the passing performance of the trolley is poor, and the risk of interference with equipment around the conveying track and the white body floor is higher; the trolley reconstruction mode of newly-added trolley rear support has the advantage that the trolley reconstruction with large workload can only be carried out during the period of non-production, so that the reconstruction period is long and generally exceeds 3 months. Not only influences the new-run trial-manufacturing progress, and the cost is also higher, and the transformation cycle also lengthens equally, influences the production order of new-run trial-manufacturing progress and current production. The platform truck space is limited, and when the supporting quantity reached a certain quantity behind the platform truck, the platform truck will not have the position to hold more back and support, can lead to new motorcycle type not to have new back to support like this and use, and the trafficability characteristic problem of new motorcycle type can't be solved.
