Description
Technical Field
[0001] This utility model relates to the field of hot riveting welding fixtures, and in particular to a hot riveting welding fixture for preventing leakage of sub-instrument panels. Background Technology
[0002] During the assembly of the Dongfeng Yipai 007 project, the L-shaped outer panel, circular trim strip, and decorative panel base were hot-riveted to ensure the gaps and surface differences between the three parts. However, the tight production schedule and the fact that the parts were welded together from three individual components made it difficult for employees to accurately and quickly weld them into a single assembly. This resulted in inconsistent gaps and surface differences between the assembly parts, and occasionally, some parts were missed during production, ultimately leading to customer complaints. Therefore, it is necessary to provide a hot riveting welding fixture for preventing the sub-instrument from being installed to solve the above-mentioned technical problems. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a hot riveting welding fixture for preventing leakage of the instrument panel.
[0004] This utility model provides a hot riveting welding fixture for an anti-leakage sub-instrument panel. The sub-instrument panel includes an L-shaped outer panel, which includes a rear panel and a decorative panel. The decorative panel has a storage hole at its center and an annular trim strip at its edge. A decorative panel seat is provided on the inner side of the decorative panel. The decorative panel, the annular trim strip, and the decorative panel seat are fixedly connected by hot riveting welding. The fixture includes a lower template and an upper template. The top of the lower template is fixed with a contour base for matching the decorative panel, a support contour base for supporting the rear panel, a controller, and an alarm. A laser sensor for detecting the presence of the L-shaped outer panel is installed inside the contour base. The laser sensor and the alarm are electrically connected to the controller. A fixture pressure plate is fixed to the bottom of the upper template by a connecting rod. Several hot riveting welding heads are installed on the fixture pressure plate.
[0005] The three parts—the L-shaped outer panel, the ring trim strip, and the decorative panel base—are placed in a welding fixture and fixed in place. Employees can then use the fixture to quickly and accurately weld the Z-axis mounting surfaces of the three parts, ensuring that the gap difference between the three parts is uniform and acceptable after welding.
[0006] The upper template descends through the sleeve of the lower template via the stepped rod, and the tooling pressure plate presses the parts with the connecting rod to ensure that the Z-direction mounting surfaces of the decorative panel, the ring trim strip and the decorative panel seat are tightly fitted.
[0007] The hot riveting welding head on the tooling plate is aligned with the preset welding point, and the hot riveting welding program is started. The hot riveting welding head fixes the three parts together by heating and melting the material, forming a uniform gap surface difference.
[0008] A laser sensor is embedded in the contour base to detect in real time whether the L-shaped outer panel is in place. If a missing part is detected, the controller triggers an alarm to prevent omissions.
[0009] Preferably, a cooling pipe is installed on the hot riveting welding head, and the cooling pipe is connected to an external air source. This allows for cooling.
[0010] Preferably, sleeves are fixed at the top four corners of the lower template, and stepped rods that cooperate with the sleeves are fixed at the bottom four corners of the upper template.
[0011] Preferably, the bottom of the upper template and the top of the lower template are symmetrically fixed with handling handles.
[0012] Preferably, the contour base is formed by splicing two contour plates.
[0013] Preferably, the contoured base is adapted to the annular trim strip and decorative panel base.
[0014] Compared with related technologies, the present invention provides the following beneficial effects: The three parts are placed in the welding fixture and fixed in place. The staff can then use the fixture to position and quickly and accurately weld the Z-axis mounting surfaces of the three parts to ensure that the gap difference between the three parts is uniform and qualified after welding.
[0015] For preventing missing parts, a laser sensor embedded in the contour base can detect in real time whether the L-shaped outer panel is in place. If a missing part is detected, the controller will immediately trigger an alarm, effectively preventing missing parts from occurring. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0019] Please refer to the following: Figures 1 to 4 A hot-riveting welding fixture for preventing leaks in a sub-instrument panel is disclosed, applicable to a sub-instrument panel structure consisting of an L-shaped outer panel 1, an annular trim strip 5, and a decorative panel seat 6. The L-shaped outer panel 1 comprises a rear panel portion 2 and a decorative panel portion 3. The decorative panel portion 3 has a storage hole 4 at its center, and an annular trim strip 5 surrounds the edge of the storage hole 4. The decorative panel seat 6 is fixed to the inner side of the decorative panel portion 3. All three components are fixedly connected by a hot-riveting welding process.
[0020] The fixture mainly consists of a lower template 7 and an upper template 8. The lower template 7 has a fixedly mounted contour base 9 matching the shape of the decorative panel 3, a support contour base 10 for supporting the rear panel 2, a controller 11, and an alarm 12. A laser sensor 13 is embedded inside the contour base 9 to detect in real time whether the L-shaped outer panel 1 is correctly positioned; both the laser sensor 13 and the alarm 12 are electrically connected to the controller 11. The bottom of the upper template 8 is fixedly connected to a fixture pressure plate 15 via a connecting rod 14, and multiple hot-riveted welding heads 16 are mounted on the fixture pressure plate 15.
[0021] In use, the three parts—L-shaped outer panel 1, annular trim 5, and decorative panel base 6—are placed in the welding fixture. After being fixed by the fixture's positioning structure, the operator can quickly and accurately perform hot riveting welding on the Z-direction mounting surfaces of the three parts, ensuring uniform and acceptable gaps and surface differences between the parts after welding. Specifically, the upper template 8 descends via the step rod 19 and the sleeve 18 of the lower template 7. The fixture pressure plate 15 presses down synchronously with the connecting rod 14, thus pressing the parts together and ensuring a tight fit between the Z-direction mounting surfaces of the decorative panel 3, annular trim 5, and decorative panel base 6. Subsequently, the hot riveting welding head 16 on the fixture pressure plate 15 is aligned with the preset welding point position, and the hot riveting welding program is initiated. The hot riveting welding head 16 uses heated and molten material to fix and connect the three parts, ultimately achieving an assembly effect with uniform gaps and surface differences.
[0022] In terms of preventing missing parts, the laser sensor 13 embedded in the contour base 9 can detect in real time whether the L-shaped outer panel 1 is placed in place. If a missing part is detected, the controller 11 will immediately trigger the alarm 12 to sound an alarm, effectively preventing missing parts from occurring.
[0023] In addition, the tooling is equipped with the following preferred structures: a cooling pipe 17 is installed on the hot riveting welding head 16, and the cooling pipe 17 is connected to an external air source, which can quickly cool the welding area after welding; sleeves 18 are fixed at the four corners of the top of the lower template 7, and stepped rods 19 that cooperate with the sleeves 18 are fixed at the four corners of the bottom of the upper template 8 to ensure the stability of the upper template 8 in raising and lowering; handling handles 20 are symmetrically fixed at the bottom of the upper template 8 and the top of the lower template 7 to facilitate the handling and movement of the tooling; the contour base 9 is made of two contour plates spliced together, and its shape can be adjusted according to actual needs to improve adaptability, and its shape is adapted to the installation position of the ring trim 5 and the decorative panel seat 6 to ensure accurate positioning of each part during welding.
