Automobile door welding flexible clamp and rotary switch flexible clamp body

Abstract

The invention discloses a flexible clamp for car door welding. Clamping mechanisms are arranged aiming at car door workpieces of different types, and positioning blocks and pressing blocks of the different clamping mechanisms are matched with positioning hook faces of the car door workpieces of the corresponding specifications. The positioning blocks are mounted on a first mounting frame around first rotary shafts, the pressing blocks are mounted on a second mounting frame around second rotary shafts, and thus the positioning block and the pressing block belonging to the same clamping mechanism can be located at a work position or a vacant position at the same time through rotary switching of the first rotary shafts and the second rotary shafts. When the positioning block and the pressingblock belonging to the same clamping mechanism are both located at the work position, the positioning block and the pressing block clamp and fix the locating hook faces of the car door workpieces of the corresponding types. Thus, the flexible clamp for car door welding can meet the clamping and positioning requirements of the car door workpieces of multiple specifications, the production input cost can be effectively reduced, the car research and development production period can be shortened, and the market competitiveness and economic benefits of enterprises can be improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical tooling fixtures, in particular to a flexible fixture for automobile door welding. Background technique [0002] Stamping process, welding process, coating process and final assembly process are the four major processes of automobile manufacturing. Their process technology and intelligent automation level greatly affect the output and quality of automobile production. The design and manufacturing costs of the welding line account for 10%-20% of the entire automobile manufacturing cost. At present, most of the domestic automobile welding lines can only carry out the welding work of one model at the same time. For the production of models, it is necessary to replace the whole set of welding fixtures. With the rise of customers' purchasing power and the increasingly intense pursuit of individualization, automobile manufacturers need to continuously launch new models to improve their market compet...
