Description

Technical Field

[0001] The invention relates to the field of welding tools, in particular to a universal front protection flexible wire harness bracket welding tool. Background Art

[0002] Usually, the front guard wire harness assembly is installed on the front guard assembly through the wire harness clip. Generally, a clip-on rib structure is designed behind the non-appearance surface of the front guard assembly for the wire harness clip. However, sometimes, due to the structure of the front guard, the clip-on rib has to be designed behind the appearance surface. The existing technology generally directly designs the rib structure behind the appearance surface or adds several wire harness brackets for wire harness clip. The disadvantage of this installation method is that the ribs directly on the appearance surface will cause injection defects, the outer surface will be concave and shrinkage will occur, and the ribs cannot be arranged in the area with the inclined roof structure. In addition, adding wire harness brackets at different positions will increase the cost. Since the bracket needs to be positioned with the skin, adding positioning ribs on the skin will also cause shrinkage risks and product molding problems.

[0003] Therefore, we propose a universal front protection flexible wire harness bracket welding tool to solve the above problems. Summary of the invention

[0023] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0024] Please refer to Figures 1 to 3 A universal front guard flexible wire harness bracket welding tool design is designed to achieve a stable installation of the wire harness bracket 1 on the car skin through precise structural arrangement and efficient welding technology. The wire harness bracket 1 is composed of a connecting part 2 connected to the skin and a wire harness clamping rib 3 vertically fixed to the connecting part 2. This welding tool includes a finely designed tool frame 4 and a matching welding head assembly 5.

[0025] The core component of the tooling frame 4 is a horizontal plate 6, with two positioning plates 7 firmly mounted at both ends. One side of each positioning plate 7 is provided with a wire harness clamping rib piece installation groove 8 specifically used to accommodate the wire harness clamping rib piece 3, and the four corners of the positioning plate 7 located on the same side of the wire harness clamping rib piece installation groove 8 are equipped with suction cups 9 to absorb and fix the connecting part 2. This design of integrating the two positioning plates 7 into one through the horizontal plate 6 not only simplifies the equipment structure, but also significantly improves the assembly efficiency.

[0026] The welding head assembly 5 includes a T-shaped connecting rod 10, with U-shaped welding parts 11 integrally formed at both ends of the connecting rod, and the U-shaped welding part 11 at each end is provided with a welding surface 12. The positioning plate 7 is specially designed with a positioning groove 13 matching the U-shaped welding part 11 to ensure accurate positioning during the welding process. By integrating the two U-shaped welding parts 11 into the T-shaped connecting rod 10, a more compact and efficient welding solution is achieved, which further simplifies the welding equipment and improves the speed and quality of the welding operation.

[0027] In order to enhance the welding effect, cylindrical protrusions 14 are evenly distributed on the welding surface 12, which can provide better contact area and fusion strength. In addition, the entire tooling frame 4 and the welding head assembly 5 adopt a design concept of vertical and horizontal symmetry, which helps to reduce production costs and ensures stability and consistency of operation.

[0028] The connection part 2 has a standard wall thickness of 1.5 mm, which takes into account flexibility and sufficient structural strength, and is suitable for the assembly requirements of large curvature surfaces and can meet the specific requirements of the welding process for wall thickness. The wire harness clamping rib 3 follows the industry standard design to ensure good wire harness management function.

[0029] Considering the convenience of installation, a chamfer 15 is provided at the entrance of the harness clamping rib installation groove 8, so that the installation of the harness bracket 1 is smoother. In addition, the tooling frame 4 also includes a vertical plate 16 vertically arranged on one side of the middle of the horizontal plate 6, and the two together form a solid T-shaped structure, which enhances the overall stability.

[0030] It is worth noting that the U-shaped welding part 11 is made of titanium alloy material, which is known for its excellent heat resistance and mechanical properties, ensuring the high quality and long-term reliability of the welding point.

[0031] Specific assembly process: first place the skin on the membrane of the welding tooling. The welding tooling is designed to be rotatable. The initial state is as follows: Figure 7 As shown, the wiring harness bracket 1 is placed on the contour tooling and then sucked by the suction cup 9, and then the tooling is rotated and welding is performed.

[0032] The contoured tooling is designed with a positioning gap of 0.2mm through the harness clamping ribs. Since the shape of the harness clamping ribs 3 determines that the harness bracket 1 can only be assembled in one direction, and since the connecting part 2 is a symmetrical structure, there is no need for error prevention. Since the skin is fixed on the tooling membrane, the final relative position of the harness bracket 1 and the skin is uniquely determined, which plays the role of tooling positioning and error prevention. The harness bracket 1 is sucked by 4 suction cups 9 to prevent the bracket from falling during the rotation of the tooling. In order to maximize the external dimensions of the bracket while meeting the pull-out force requirements after welding of the bracket, the welding head (U-shaped welding part 11) is designed in the hollowed-out avoidance position of the tooling. The welding head (U-shaped welding part 11) size of 20mm*10mm just meets the pull-out force requirements after welding. The suction cup 9 with a diameter of 10mm is also the minimum size designed to absorb the connection part 2. The minimum gap between the welding head (U-shaped welding part 11) and the tooling frame 4 is 1mm. To prevent the suction cup 9 from leaking, a gap of 1mm is left between the suction cup 9 and the edge of the connection part 2. Therefore, the minimum size of the bracket is 1+10+1+20+1+10+1=44mm, so 44*44mm is the limit size of the connection part 2.

[0033] In addition, if Figure 8 As shown, after the welding of the harness bracket 1 is completed, the welding tool needs to perform two actions to exit. The first step is to translate along the assembly direction of the harness bracket 1, that is, the normal direction of the large surface of the harness bracket 1. When the tool is completely disengaged from the harness clamping rib 3, the second step is to rotate it out and then take out the product. If the tool is rotated directly without the translation action, it will interfere with the harness clamping rib and cannot be removed.

[0034] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
