Abstract
Description
Technical Field
[0001] This application relates to the field of automotive instrument panel crossbeam manufacturing technology, and in particular to a welding slag protection tool for automotive instrument panel crossbeam studs. Background Technology
[0002] The instrument panel crossbeam is a crucial component of a car's interior, serving multiple functions and critical roles. It acts as a structural element, providing mounting and support for the instrument panel assembly and other system parts (such as the steering column, air conditioning, entertainment system, instrument cluster, and front passenger-side airbag). Directly connected to the vehicle body, it not only forms the robust foundation of the instrument panel assembly but also plays a vital role in connecting the vehicle's structure with passenger safety. In a collision, the instrument panel crossbeam withstands, absorbs, and transfers energy and loads, making it essential for occupant protection.
[0003] The instrument panel crossbeam has a complex and precise structure, mainly consisting of components such as the main beam, instrument panel connecting brackets, column mounting brackets, and body connecting brackets. The main beam is the primary load-bearing part of the crossbeam and is typically made of lightweight metal. To ensure precise assembly of the instrument panel crossbeam within the vehicle and its connection to various interior components, the main beam usually incorporates multiple mounting plates and other components, such as… Figure 1 The structure shown in the figure also includes studs on the assembly plate, which are used for assembling accessories and connecting parts.
[0004] Currently, in the production and processing of instrument panel crossbeams, due to the design of multiple welded components on the main crossbeam, weld slag spatter is inevitable during the welding process. This slag can adhere to the studs pre-installed on the assembly plate, affecting the smooth (threaded) connection with the studs during the later automotive assembly process. Since automotive assembly is a streamlined process, time is not allocated for cleaning the weld slag from the studs, and these are usually considered defective products, requiring rework to the instrument panel crossbeam supplier for unified processing. This process impacts assembly efficiency, and the cost of rework is high. Summary of the Invention
[0005] To address the aforementioned problems, this application aims to provide a welding slag protection tool for automotive instrument crossbeam studs, which can effectively prevent welding slag from splashing and adhering to the studs, thereby solving the problem of the entire crossbeam having to be returned to the factory due to the influence of welding slag on the studs during the later assembly process.
[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: a welding slag protection tool for automotive instrument crossbeam studs, wherein the studs are welded to the assembly plate of the crossbeam, characterized in that: the protection tool detachably covers the studs on the crossbeam, and the protection tool is also provided with a fastening component that is relatively fixed to the crossbeam in the crossbeam rotation state.
[0007] Preferably, the protective tool includes a support plate, on one side of which are evenly distributed protective sleeves corresponding to each of the studs and which can be fitted onto the studs.
[0008] Preferably, a rubber cylinder is also embedded inside the protective sleeve, and the inner wall of the rubber cylinder is configured as a conical structure.
[0009] Preferably, the fastening member is a fastening bolt that passes through the outer wall of the protective sleeve and can drive the rubber sleeve to abut against the stud.
[0010] The beneficial effects of this application are: the weld slag protection tool can detachably cover the studs on the crossbeam, effectively preventing weld slag from splashing and adhering to the studs. Furthermore, the fastening components can lock the protection tool to the studs it covers, thus ensuring a secure connection between the protection tool and the crossbeam. This allows the tool to rotate with the crossbeam, guaranteeing protection of the studs throughout the entire welding process. This solves the problem of the entire crossbeam having to be returned to the factory due to weld slag on the studs during final assembly. Attached Figure Description

[0018] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of this application will be further described below in conjunction with the accompanying drawings and embodiments.
[0019] See attached document Figures 1-6The illustration shows a slag protection tool for automotive instrument panel crossbeam studs. The studs 2 are welded to the assembly plate 11 of the crossbeam 1. To prevent slag from splashing and adhering to the studs 2 during the welding of other structural components on the crossbeam 1, thus affecting subsequent assembly, this application designs a slag protection tool, such as... Figure 4-5 As shown, it can detachably cover the studs 2 on the crossbeam 1. That is, when welding other components on the crossbeam 1, the studs 2 can be covered and sealed, effectively preventing weld slag from splashing and adhering to the studs 2. After the overall welding of the crossbeam 1 is completed, this protective tool can be disassembled and used in the next welding operation of the crossbeam 1. It serves as an auxiliary tool for welding the crossbeam 1, effectively solving the problem of needing to return the equipment to the factory due to weld slag.
[0020] Because there are many components welded at different locations on the crossbeam 1, the crossbeam 1 needs to be continuously rotated during actual welding operations. Therefore, to prevent the protective tool from falling off during the rotation of the crossbeam 1, the protective tool is also equipped with a fastening component that is fixed relative to the crossbeam 1 while the crossbeam 1 is rotating. This fastening component can lock the protective tool to the stud 2 it covers, thereby ensuring that the protective tool is relatively secure to the crossbeam 1 and can protect the stud 2 throughout the entire welding operation of the crossbeam 1, as the crossbeam 1 is rotated.
[0021] Specifically, such as Figure 2-3 As shown, the protective tool includes a support plate 3, on one side of which are evenly distributed protective sleeves 4 corresponding to each stud 2 and capable of being fitted onto the stud 2. Each protective sleeve 4 corresponds one-to-one with a stud 2, and since automobiles are typically mass-produced, this protective tool can be used continuously in the current batch of models. In use, as... Figure 4 As shown, by holding the support plate 3, each protective sleeve 4 corresponds to each stud 2, and the protective sleeve 4 is put on each stud 2 to cover it. In the later welding operation, the problem of welding slag splashing and sticking to the stud 2 is avoided. After the welding is completed, the protective sleeve 4 can be removed and used for the welding operation of the next crossbeam 1.
[0022] When the stud 2 is protected by the protective sleeve 4, the protective sleeve 4 is very likely to come into contact with the threads on the surface of the stud 2. Furthermore, if the insertion force is too high, the protective sleeve 4 may cause wear on the external threads of the stud 2, affecting subsequent assembly. Therefore, to solve this problem, such as... Figure 6 As shown, a rubber sleeve 5 is also embedded in the protective sleeve 4. Through the soft structure of the rubber sleeve 5, it can avoid damage to the external thread of the stud 2 after contacting it, which can effectively avoid the problem of having to return the stud 2 to the factory due to damage.
[0023] The welding of the instrument beam is also a batch welding process. Therefore, to ensure the protective sleeve 4 can be smoothly fitted onto the stud 2, as follows: Figure 6 As shown, the inner wall of the rubber cylinder 5 is designed with a conical structure. This conical structure increases the inner diameter of the outer port of the rubber cylinder 5, and this larger port structure facilitates quick and smooth insertion into the stud 2, effectively improving operational efficiency in mass production.
[0024] To achieve a relatively tight fit between the protective sleeve 4 and the crossbeam 1, such as Figure 6 As shown, the fastening component is a fastening bolt 6 inserted into the outer wall of the protective sleeve 4, which drives the rubber sleeve 5 to abut against the stud 2. After the protective sleeve 4 and the rubber sleeve 5 are fitted onto the stud 2, rotating the fastening bolt 6 drives the side wall of the rubber sleeve 5 to abut against the stud 2, thus achieving relative fastening of the entire protective tool to the crossbeam 1. This prevents the protective tool from falling off during the flipping and welding operation of the crossbeam 1. To facilitate the rotation of the fastening bolt 6, it is preferably a winged bolt, which facilitates manual tightening and disassembly.
[0025] The principle of this application is as follows: When using the welding slag protection tool, by holding the support plate 3, each protective sleeve 4 corresponds to each stud 2, and the protective sleeve 4 and rubber sleeve 5 are fitted onto each stud 2 to cover it. Then, by rotating and tightening the bolt 6, the entire protection tool can be fixed on the crossbeam 1. During the entire operation of the crossbeam 1 flipping and welding, the protective sleeve 4 effectively blocks the splashing welding slag, thereby solving the problem of returning to the factory during the later assembly process.
[0026] The foregoing has shown and described the basic principles, main features, and advantages of this application. Various changes and modifications may be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
