Description

Technical Field

[0002] With the development of lightweight new energy vehicles, carbon fiber composite materials, engineering plastics and other non-metallic materials are widely used in interior parts. Their structures have multi-curved and thin-walled features (such as door panel decorative strips and instrument panel frames). During the production process of automotive interior accessories, welding between accessories is required. Traditional tooling is difficult to adapt to the highly integrated installation requirements of new energy vehicles.

[0003] After searching, in the prior art, the Chinese patent application number CN202010680832.8 discloses "A welding fixture for new energy vehicles", which relates to the technical field of welding fixtures, including: a support platform, a workbench, a clamping part, an adjustment part and a detection part. The workbench is rotatably connected to the support platform; the clamping part is arranged on the top of the workbench for fixing the automobile interior decoration parts; the adjustment part is transmission-connected to the workbench for adjusting the rotation angle of the workbench; the detection part includes two first brackets symmetrically arranged on the top of the workbench, a top bracket is fixedly connected between the two first brackets, a second bracket is movably connected between the two first brackets, a first slider is slidably connected to the second bracket, a laser lamp is hinged on the first slider, and a scale line is provided at the bottom of the top bracket. The laser lamp irradiates the laser to the bottom of the top bracket. The size of the laser is observed through the scale line. When the size of the laser on the top bracket is the same as the size of the laser on the laser lamp, it indicates that the laser lamp is in a vertical state. The above-mentioned fixture improves the welding efficiency of rivet columns with different inclination angles, but still has the following defects:

[0061] Specifically, when the welding tool for installing new energy interior parts is in operation: when the distance between the upper rack 3 and the lower rack 4 needs to be adjusted, the worker manually rotates the gripping plate 207, which drives the bidirectional threaded rod 204 to rotate; because the threads at both ends of the bidirectional threaded rod 204 are in opposite directions, when the bidirectional threaded rod 204 rotates, the two sets of U-shaped slides 205 will move closer to or away from each other along the slide rod 206, thereby adjusting the distance between the upper rack 3 and the lower rack 4 to accommodate automobile interior parts of different heights;

[0062] The car interior component is then placed between the upper rack 3 and the lower rack 4. The worker manually rotates the gripping handle 502, which drives the screw 501 to rotate.

The relative sliding of the second half-moon-shaped clamping block 7 and the third half-moon-shaped clamping block 8 can adapt to interior decoration parts of different shapes and realize preliminary clamping of automobile interior decoration parts. Therefore, when clamping automobile interior decoration parts of irregular shapes, the fixture and the interior decoration parts are more closely fitted, thereby reducing the defective rate of products after welding;

[0064] The air pump 903 is started by controlling the control panel 10. The air pump 903 inflates the hollow plate 902. The gas enters the piston cylinder 912 through the gas pipe 905, pushing the positioning post 911 out. The positioning post 911 contacts the automobile interior part to assist in positioning it.

[0065] At the same time, by controlling the air pressure of the air pump 903, a certain pressure can be applied to the car interior parts to ensure that the interior parts fit tightly during the welding process;

[0066] After welding is completed, the air release valve 904 is opened to discharge the gas in the hollow plate 902 , the air pipe 905 and the piston cylinder 912 , and the positioning column 911 is reset under the action of the reset spring 913 .

[0067] All technical features in this embodiment can be freely combined according to actual needs.
