Technical Field
[0001] This utility model relates to the field of automotive assembly technology, and in particular to an off-road module and a tire pressure monitoring receiver assembly and positioning device. Background Technology
[0002] In the assembly process of mass-produced off-road vehicles in the final assembly workshop, the off-road module, off-road module bracket, tire pressure monitoring receiver, and sub-instrument panel bracket are assembled. Before installing the module assembly, the off-road module needs to be disassembled into the off-road module bracket to become the off-road module assembly, the off-road module assembly needs to be disassembled into the sub-instrument panel bracket, and the tire pressure monitoring receiver needs to be disassembled into the sub-instrument panel bracket before the whole assembly is pre-assembled.
[0003] Because the four corners of the off-road module bracket and the auxiliary instrument panel bracket are not on the same horizontal plane, the existing workbench cannot be fixed. The off-road module assembly and the tire pressure monitoring receiver are installed on both sides of the auxiliary instrument panel bracket. Currently, the sub-assembly operation requires two workers to work together to tighten them. The sub-assembly time is long. With two workers working together, it takes 5 minutes to sub-assemble a single vehicle, which does not meet the production rhythm of the final assembly workshop, and pre-assembly must be carried out. During the sub-assembly process, the lack of fixing of parts can easily cause quality problems such as scratches on the bracket or module. Without a fixed sub-assembly table, when two workers work together, one person holds the bracket upright and the other tightens it. During the operation, the impact wrench can slip off the screw and cause work-related injuries.
[0004] Therefore, it is urgent to design an off-road module and tire pressure monitoring receiver separate mounting and positioning device to solve the above problems. Utility Model Content
[0005] The purpose of this utility model embodiment is to provide a sub-assembly and positioning device for off-road modules and tire pressure monitoring receivers, which solves the problems that the brackets cannot be fixed on the workbench, require two workers to work together to tighten them, result in long sub-assembly time, and are prone to scratches on the brackets or modules.

[0009] The second assembly platform is equipped with a secondary instrument panel bracket limit block;
[0010] The off-road module bracket limit block and the sub-instrument panel bracket limit block are used to constrain the displacement of the off-road module bracket and the sub-instrument panel bracket after positioning them in the X and Y directions, respectively.
[0011] Optionally, the first and second sub-assembly platforms are respectively mounted on corresponding bases A and B; and in order to ensure assembly quality and prevent the sliding of parts and sub-assembly platforms, bases A and B are metal plate structures with anti-slip treatment layers on their surfaces.
[0012] Optionally, the off-road module bracket limiting block is machined with an off-road module bracket positioning groove that conforms to the shape of the off-road module bracket, which is used to securely fasten the off-road module bracket.
[0013] The off-road module bracket is placed on the first sub-assembly platform and fixed by the off-road module bracket positioning groove and the off-road module bracket limiting block. The off-road module is placed on the off-road module bracket and vertically tightened using a battery impact wrench to assemble it into an off-road module assembly.
[0014] Optionally, a positioning groove for the sub-instrument panel bracket, which conforms to the shape of the sub-instrument panel bracket, is machined on the sub-instrument panel bracket limiting block to securely fasten the sub-instrument panel bracket.
[0015] Optionally, the off-road module assembly is placed on the second sub-assembly platform, and the sub-instrument panel bracket is placed above the off-road module assembly. It is then fixed by the sub-instrument panel bracket limit block and the sub-instrument panel bracket positioning groove, and assembled by vertically tightening it with a battery impact wrench.
[0016] Next, place the tire pressure monitoring receiver on top of the auxiliary instrument panel bracket and use a battery impact wrench to vertically tighten it for assembly.
[0017] The present utility model application has the following beneficial effects:
[0018] This sub-assembly positioning device uses the shape of the parts to be assembled and the stress on the bracket during the sub-assembly process to customize the limiting blocks and positioning grooves on the sub-assembly table. This ensures that one worker can complete the sequential assembly of four different parts in a short time, shortening the sub-assembly time and meeting the production rhythm of the final assembly workshop. The bracket is firmly limited and accurately positioned, while eliminating product quality problems caused by sub-assembly without a fixed position, thus improving the first-pass yield of the whole vehicle.

[0028] As attached Figure 1 -Appendix Figure 7 As shown, this utility model embodiment provides an off-road module and tire pressure monitoring receiver sub-assembly and positioning device, which can solve the problem that during the assembly of various brackets in mass-produced off-road vehicles in the existing final assembly workshop, the four corners of the brackets are not on the same horizontal plane, the existing worktable cannot be fixed, the sub-assembly time is long, it does not meet the production rhythm of the final assembly workshop, and affects the quality of assembled products. The sub-assembly and positioning device includes a first sub-assembly table 1 and a second sub-assembly table 2, and limit blocks are respectively set on the two sub-assembly tables. Positioning grooves that conform to the shape of each bracket are machined on the limit blocks. Other necessary components that make up this device are not mentioned here, and the conventional structure of these components is common knowledge.
[0029] The first sub-assembly platform 1 and the second sub-assembly platform 2 are respectively installed on the corresponding bases, namely base A5 and base B6. The two bases are metal flat plate structures with anti-slip treatment layers on the surface to prevent the parts and sub-assembly platforms from sliding and to ensure the positioning and assembly effect of the bracket. Limiting blocks are set on the two sub-assembly platforms of the sub-assembly positioning device. The first sub-assembly platform 1 is equipped with an off-road module bracket limiting block 3, and the second sub-assembly platform 2 is equipped with a secondary instrument panel bracket limiting block 4. The two limiting blocks are used to constrain the displacement of the off-road module bracket or the secondary instrument panel bracket after positioning them in the X and Y directions, respectively.
[0030] When assembling the off-road module bracket and the auxiliary instrument panel bracket, the final assembly workshop, based on the assembly sequence of components such as the off-road module bracket and the auxiliary instrument panel bracket, and considering the shapes of the four components—the off-road module, the off-road module bracket, the auxiliary instrument panel bracket, and the tire pressure monitoring receiver—and the stress conditions of the brackets during the sub-assembly process, customized this sub-assembly positioning device. Specifically, the off-road module bracket limiting block 3 (as shown in the attached figure) is installed at a suitable position on the base A5 of the first sub-assembly table 1. Figure 1 As shown, all protrusions on base A5 are limiting blocks (not fully indicated in the attached diagram). The height and dimensions of the off-road module bracket limiting block 3 match the part of the off-road module bracket to be fixed and limited. An off-road module bracket positioning groove 7, conforming to the shape of the off-road module bracket, is machined on the off-road module bracket limiting block 3 (as shown in the attached diagram). Figure 1 As shown, according to the custom design of the off-road module bracket, the off-road module bracket positioning groove 7 is machined on the off-road module bracket limiting block 3. The second sub-assembly platform 2 is equipped with a secondary instrument panel bracket limiting block 4 (as shown in the attached figure). Figure 2 As shown, all protrusions on base B6 are limiting blocks (not fully marked in the attached diagram).

A secondary instrument panel bracket positioning groove 8, conforming to the shape of the secondary instrument panel bracket, is machined on the secondary instrument panel bracket limiting block 4 (as shown in the attached diagram). Figure 2 As shown, a positioning groove 8 for the sub-instrument panel bracket is machined on the sub-instrument panel bracket limiting block 4, which is custom-designed according to the shape of the sub-instrument panel bracket.
[0031] During assembly, first place the off-road module bracket on the first sub-assembly platform 1, and use the off-road module bracket positioning groove 7 and the off-road module bracket limiting block 3 to limit and fix it in the X and Y directions (the X and Y directions are not marked in the attached drawing). Securely fasten the off-road module bracket (as shown in the attached drawing). Figure 3 As shown), constrain the displacement of the off-road module bracket, place the off-road module on the off-road module bracket at the installation position, and use a battery impact wrench to vertically tighten and assemble it into an off-road module assembly (as shown in the attached diagram). Figure 4(As shown), then flip the off-road module assembly upside down and place it on the second assembly platform 2. Match the auxiliary instrument panel bracket limit block 4 with the part of the off-road module assembly to be fixed and limit it, and snap the off-road module assembly into the limit position (as shown in the attached figure). Figure 5 As shown in the attached diagram, the secondary instrument panel bracket is placed above the off-road module assembly, and fixed in the X and Y directions by the secondary instrument panel bracket limiting block 4 and the secondary instrument panel bracket positioning groove 8 (as shown in the attached diagram). Figure 6 As shown), use a battery impact wrench to vertically tighten and assemble. Continue by placing the tire pressure monitoring receiver above the center console bracket and using a battery impact wrench to vertically tighten and assemble (as shown in the attached diagram). Figure 7 As shown in the diagram, the off-road module is now assembled onto the off-road module bracket to form the off-road module assembly. The off-road module assembly is then assembled onto the secondary instrument panel bracket, and the tire pressure monitoring receiver is also assembled onto the secondary instrument panel bracket. The off-road module assembly and the tire pressure monitoring receiver are respectively installed on both sides of the secondary instrument panel bracket.

[0033] This utility model's sub-assembly positioning device is customized by integrating the shapes of four components—the off-road module, the off-road module bracket, the auxiliary instrument panel bracket, and the tire pressure monitoring receiver—and the stress conditions of the bracket during the sub-assembly process. This ensures that one worker can complete the sequential assembly of the four different components in a short time, eliminating the assembly bottleneck at this sub-assembly station, shortening the sub-assembly time, and meeting the production rhythm of the final assembly workshop. The bracket provides firm and accurate positioning, while eliminating product quality problems caused by sub-assembly without a fixed position, improving the first-pass yield of the whole vehicle, and reducing the occurrence of work-related accidents.
