Embodiment Construction
[0045] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.
[0046] Such as figure 1 As shown, it is a structural schematic diagram of an embodiment of the automobile door welding flexible fixture of the present invention. The automobile door welding flexible fixture of this embodiment includes a fixture substrate 1, and the fixture substrate 1 is provided with:
[0047] The positioning support clamp body 100 is used to cooperate with the positioning hole of the door workpiece and reduce the normal deformation of the door workpiece;
[0048] The plane clamping fixture body 200 is used to clamp the positioning plane of the door workpiece and prevent the normal deformation of the door workpiece;
[0049] The car door window frame clamping b...

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 welding work for 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 competiti...
