Problems solved by technology

[0005] At present, the main methods of automatic replacement of body positioning fixtures are as follows: A. Use the rotary indexing workbench as the storage warehouse for the body positioning fixture frame, rotate to the required storage position of the body positioning fixture frame and translate to the body welding station; It can meet the mixed-flow production of 4 models. The body positioning fixture storage system using the A method requires a space of 22m×18m for the placement of the body positioning fixtures, which occupies a large area, and there are few models that can be welded; B. Using a roller-type workbench As a storage warehouse for the body positioning jig frame, after flipping to the required storage position of the jig frame, and then moving to the body wel

Abstract

The invention discloses a system for automatically changing multi-vehicle type car body positioning fixtures for flexible welding of a robot. The system comprises a central positioning mechanism and a storage mechanism, wherein the storage mechanism comprises two sets of movable storage mechanisms which are symmetrically arranged on two sides of the central positioning mechanism, and each set of movable storage mechanism comprises a Y-direction track, a movable lifting mechanism and a car body positioning fixture storage arranged above the Y-direction track. According to the system, movable storage mechanisms which can move in the X direction, the Y direction and the Z direction are adopted, and only 15m*20m space is required for storing the car body positioning fixtures. The system is simple in structure and flexible and convenient to operate, and can be completely matched with a production line, so that synchronization production of any mixing of 1-6 types of vehicles can be realized.

Description

technical field [0001] The invention relates to the field of automobile body welding in an automobile production line, in particular to an automatic replacement system and an automatic replacement method for a body positioning fixture for multi-model automobile body robot flexible welding. 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,...
