Detailed Description
The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1 to 4: a flexible pressing device for laser flying welding of a body-in-white comprises a supporting plate 1 used as a base, a plurality of flexible pressing units 2 distributed in an array manner are arranged on the supporting plate 1,
the flexible pressing unit 2 comprises a support frame 3 directly fixedly connected with the support plate 1, the support frame 3 is rotatably connected with a swinging piece 5 through a rotating shaft 4, the swinging piece 5 is connected with an L-shaped pressing piece 6, the L-shaped pressing piece 6 consists of a vertical part 7 and a horizontal part 8 which are mutually connected and vertical to each other, the top of the vertical part 7 is provided with a unthreaded hole, a connecting bolt 9 is movably connected in the unthreaded hole in a penetrating manner, the connecting bolt 9 is in threaded connection with a threaded hole formed in the swinging piece 5, the vertical part 7 is also provided with a pin hole 10 positioned below the unthreaded hole, a positioning pin shaft is arranged in a matching manner with the pin hole 10, the swinging piece 5 is provided with a swinging piece pin hole matched with the positioning pin shaft, and the inner diameter of the unthreaded hole is larger than the outer diameter of the connecting bolt 9,
the top end face of the swinging piece 5 is connected with a spring 11, the spring 11 is connected in a spring through hole formed in the supporting plate 1 in a penetrating mode, the top end of the spring 11 is connected with a fixing block 12, the fixing block 12 is fixedly connected to the supporting plate 1 through a bolt, a gasket 13 is further arranged between the fixing block 12 and the supporting plate 1, and a gasket through hole for the spring 11 to pass through is formed in the gasket 13.
The utility model discloses white automobile body laser flight welding flexible pressing device's working process as follows: different workpieces needing to be subjected to flight welding operation are placed on a welding platform, after the relative positions of the workpieces are determined through positioning devices such as positioning clamps, a lifting mechanism is started, the lifting mechanism drives a supporting plate 1 in the device to integrally move towards the direction of the workpieces, all flexible pressing units 2 are located below the supporting plate 1 at the moment, after the flexible pressing units 2 are in contact with the surfaces of the workpieces, an L-shaped pressing piece 6 (specifically, a horizontal part 8 in the L-shaped pressing piece 6) which is directly in contact with the workpieces swings together with a swinging piece 5 under the reaction force of the workpieces so as to adapt to the shape of the surface of the workpiece in contact with the swinging piece, and each flexible pressing unit 2 can be subjected to the adaptive adjustment, so that after the supporting plate 1 moves in place, all the workpieces are pressed by the plurality of flexible pressing units 2, and subsequent laser flight welding operation can be carried out;
because the swinging piece 5 and the L-shaped pressing piece 6 are connected into a whole structure through the connecting bolt 9, when the horizontal part 8 in the L-shaped pressing piece 6 is contacted with the surface of a workpiece and bears the reaction force of the workpiece, the swinging piece 5 and the L-shaped pressing piece 6 swing together around the rotating shaft 4,
meanwhile, when the L-shaped pressing piece 6 is installed, the connecting bolt 9 is not screwed, namely the head of the connecting bolt 9 cannot press the vertical part 7 of the L-shaped pressing piece 6 on the swinging piece 5, and meanwhile, because the inner diameter of the unthreaded hole where the connecting bolt 9 is located is larger than the outer diameter of the connecting bolt 9, the L-shaped pressing piece 6 can swing by taking the positioning pin shaft as an axis when external force is applied;
the swinging in the two directions enables the L-shaped pressing piece 6 in the device to be adjusted according to the shape of the workpiece, and the pressing unit array consisting of the plurality of flexible pressing units 2 can ensure the stable pressing of the workpiece;
when the device works, the pressing force provided by each flexible pressing unit 2 comes from the spring 11, and after the supporting plate 1 integrally moves upwards, all the L-shaped pressing pieces 6 in the flexible pressing units 2 return to wait for the next pressing operation under the action of the spring 11; the pressing force of each flexible pressing unit 2 on the workpiece can be adjusted by replacing the spacers 13 with different ditches.
