Flexible forming machine for total assembly of vehicle models for air storage

Abstract

The invention discloses a flexible forming machine for a total assembly of vehicle models for air storage. The flexible forming machine comprises central positioning mechanisms and a clamp storage mechanism. The clamp storage mechanism comprises elevating storage storerooms, fixed storage storerooms and track switching mechanisms. The two sets of elevating storage storerooms and the fixed storage storerooms are arranged at two sides of the central positioning mechanisms. The track switching mechanisms are arranged above the central positioning mechanisms. The method of application comprises following steps: selecting positioning clamps based on concrete vehicle models; pre-reading a second vehicle model while preparing positioning clamps in advance for moving the second vehicle model to the central positioning mechanisms so that replacement of clamps is finished. Therefore, the positioning clamps of the positioning clamps for vehicle bodies can be placed in the space with the area of 12m*18m. The flexible forming machine is simple in structure and flexible and convenient in operation and is in full accord with takt of a production line so that synchronous production of arbitrary combined flow of multiple vehicle models is achieved.

Description

technical field [0001] The invention relates to the field of automobile welding in an automobile production line, in particular to an air-stored vehicle assembly flexible forming machine. Background technique [0002] The development trend of the world's automobiles is from mass production to multi-variety and small-batch production. In order to meet the extensive and diverse needs of automobile consumers and adapt to the fierce competition in the automobile market, major automobile manufacturers in the world continue to shorten the model change cycle. To speed up the update of vehicle types, the flexible body welding line (FBL) is designed and manufactured to adapt to this development trend. It can produce the car bodies of two or more car models in a mixed flow on one production line, and has the advantages of simple and fast changeover production, short development time, low secondary investment costs and high production efficiency, so it is widely used by major automobil...

Problems solved by technology

[0007] B. Use the roller-type workbench as the storage warehouse for the vehicle positioning fixture frame, turn it over to the required storage position for the fixture frame, and then move it to the body assembly and welding station through translation. The vehicle positioning fixture storage system of the B method is adopted, although only 22m×13m is required However, due to the complex structure and high manufacturing cost of the roller-type workbench, the investment cost of the entire system increases, and it is necessary to set a high roller-type workbench on the production line. Security risks;

[0008] C. The jig frame is replaced by means of two left and right trolleys that can move in the X and Y directions. The vehicle positioning jig storage system using the C method requires at least 29m×18m space for the placement of the vehicle positioning jig, occupying The land area is very large, resulting in high investment costs for the entire system
