Description

Technical Field

[0001] The utility model relates to the technical field of automobile assembly, in particular to a reversible workbench. Background Art

[0002] Under the JIT supply model, multiple car models are often produced on the same line, and the time requirements for switching tire molds for the production of different car models are relatively high. The existing production and processing for different car models usually include two methods. One is to use different workbenches to meet the processing requirements of different car models. Each workbench supports the tire mold on one side and is fixed and cannot be switched.
