[0029] Combination Figure 1 , Figure 3 and Figure 4 As shown, the utility model discloses a positioning tool for a frame panel assembly, which is used to simultaneously position the hinge upper support 200, the lock hook fixing plate 300 and the zipper bracket mounting plate 400 on the panel 100. The positioning tool includes a tool body 1 for simulating the position of the side door for overall positioning, a first positioning component 2 installed in cooperation with the tool body 1, a second positioning component 3 installed in cooperation with the tool body 1, and a limit component; the tool body 1 is provided with a positioning groove 11 matching the shape of the zipper bracket mounting plate 400; the first positioning component 2 includes a hinge upper support positioning component 100, a lock hook fixing plate 300 and a zipper bracket mounting plate 400; the first positioning component 2 includes a hinge upper support positioning component 100, a lock hook fixing plate 300 and a zipper bracket mounting plate 400; the lock hook fixing plate 300 includes a lock hook fixing plate 3 ... The positioning pin 21 and the hinge upper support positioning block 22 provided with a positioning hole, the hinge upper support positioning pin 21 passes through the through hole of the hinge upper support 200 and is inserted into the positioning hole of the hinge upper support positioning block 22, so that the hinge upper support 200 is close to the hinge upper support positioning block 22; the second positioning component 3 includes a lock hook fixing plate positioning pin 31, the lock hook fixing plate positioning pin 31 passes through the tooling body 1 and is inserted into the installation hole 301 of the lock hook fixing plate 300 placed under the tooling body 1; the limiting component is installed in cooperation with the tooling body 1, and is used to limit the position of the tooling body 1 on the enclosure 100.

[0030] The tool body 1 in the utility model is the core part of the entire positioning tool. Its shape and size are designed according to the actual position and size of the enclosure assembly and the side door to ensure that the position of the side door when closed can be accurately simulated. The tool body 1 is usually made of a solid metal material to ensure its stability and durability.

[0031] The positions of the hinge upper support 200 and the lock hook fixing plate 300 on the panel assembly are related to the concentricity of the side door shaft and the side door gap, and the zipper bracket mounting plate 400 is related to the door lock switch. At present, the workshop uses the marking method to assemble the hinge upper support 200, the lock hook fixing plate 300 and the zipper bracket mounting plate 400 on the panel 100, which is inefficient, poor in precision, and cannot guarantee quality, which seriously affects the installation of the side door and the appearance quality of the whole vehicle.

[0032] Through the coordinated action of the tooling body 1, the first positioning component 2, the second positioning component 3 and the limit component, the hinge upper support 200, the lock hook fixing plate 300 and the zipper bracket mounting plate 400 on the enclosure 100 can be precisely positioned at the same time, effectively avoiding the cumulative errors that may be caused by the installation of individual components one by one in the traditional method, improving the overall installation accuracy, simplifying the assembly process, and reducing the time for repeated positioning and correction, thereby significantly improving the assembly efficiency of the frame enclosure assembly. Accurate positioning and stable installation ensure that the relative positions of the various components on the enclosure assembly are accurate, which helps to improve the structural strength and sealing of the entire vehicle, reduce quality problems caused by improper installation, and thus ensure the overall quality of the product. Moreover, after using the positioning tooling, the operator only needs to assemble according to the established steps, reducing the links of manual judgment and adjustment, and reducing labor intensity.

[0033] The zipper bracket mounting plate 400 in the present invention is closely attached to the positioning groove 11 on the tool body 1 which matches the shape of the zipper bracket mounting plate 400 , so as to realize the positioning of the zipper bracket mounting plate 400 on the enclosure 100 .

[0034] The first positioning assembly 2 in the utility model is mainly used to position the hinge upper support 200. The hinge upper support 200 is placed at a predetermined position on the enclosure 100, and its through hole is aligned with the corresponding position on the tooling body 1. The hinge upper support positioning pin 21 passes through the through hole of the hinge upper support 200 and is accurately inserted into the positioning hole of the hinge upper support positioning block 22. The hinge upper support positioning block 22 is fixed on the tooling body 1, and the hinge upper support 200 is closely attached to the hinge upper support positioning block 22 through the cooperation of the hinge upper support positioning pin 21 and the positioning hole, thereby realizing the accurate positioning of the hinge upper support 200 on the enclosure 100.

[0035] The limit assembly in the utility model can be customized and adjusted according to different application scenarios and needs. Whether changing the size, shape or material, it can be flexibly designed according to the characteristics and restrictions of the enclosure 100 to meet specific usage requirements and ensure the stable position of the tooling body 1 on the enclosure 100. The limit assembly may include a plurality of limit blocks or limit pins, which are installed around the tooling body 1 and are in close contact with the corresponding structures (such as edges, bosses, grooves, etc.) on the enclosure 100, thereby limiting the range of movement of the tooling body 1. During installation, the various components of the limit assembly are installed one by one at the corresponding positions of the tooling body 1, and their positions are adjusted to ensure a close fit with the enclosure 100. After the installation is completed, the limit assembly will effectively prevent the tooling body 1 from moving or tilting during the subsequent installation process.

[0036] Specifically, Figure 2 and Figure 4 As shown, the side of the tool body 1 is provided with a mounting groove for installing the limit assembly, the top surface of one end of the tool body 1 is provided with a first step surface 15 for installing the first positioning assembly 2, and the top surface of the tool body 1 is also provided with a second step surface 16 protruding upward, and the second step surface 16 is provided with a positioning through hole 161 corresponding to the mounting hole 301 of the lock hook fixing plate 300. Further, the hinge upper support positioning block 22 is installed on the first step surface 15; the lock hook fixing plate positioning pin 31 corresponds to the positioning through hole 161 on the second step surface 16.

[0037] The mounting groove can be designed to match the shape and size of the limit assembly to ensure that the limit assembly can be firmly installed on the tooling body. The number, position and size of the mounting grooves are customized according to the specific needs of the limit assembly. It is understandable that the process parameters such as the depth, width and length of the mounting grooves need to meet the installation requirements of the limit assembly, and leave appropriate tolerances to ensure installation flexibility. By setting the mounting groove on the side of the tooling body 1, the limit assembly can be accurately installed in place, effectively avoiding the problem of position offset or loose installation that may occur in the traditional installation method.

[0038] The first step surface 15 is provided on the top surface of one end of the tool body 1 for installing the hinge upper support positioning block 22. The height, width and shape of the first step surface need to match the bottom of the hinge upper support positioning block 22 to ensure the stable installation of the hinge upper support positioning block 22.

[0039] According to the position and size of the mounting hole 301 of the lock hook fixing plate 300, the height, width and shape of the second step surface 16 are designed on the tool body 1, and a positioning through hole 161 corresponding to the mounting hole 301 is processed on the second step surface 16. A gap is formed between the upwardly protruding second step surface 16 and the enclosure 100 for placing the lock hook fixing plate 300, and the lock hook fixing plate positioning pin 31 is passed through the positioning through hole 161 and inserted into the mounting hole 301 of the lock hook fixing plate 300 to achieve accurate positioning of the lock hook fixing plate 300.

[0040] The design of the mounting groove, the first step surface 15 and the second step surface 16 not only provides a mounting position, but also enhances the structural stability of the tooling by increasing the structural level and contact area of ​​the tooling body 1. This helps to resist external impact and vibration during the working process and prolong the service life of the tooling. The design has a clear mounting position and positioning structure (such as the positioning through hole 161), making the installation process more intuitive and convenient. The operator can quickly complete the installation and positioning of each component without excessive adjustment and calibration, thereby improving work efficiency.

[0041] In addition, the design concept of the tooling body 1 embodies a modular design. Through standardized design elements such as mounting grooves, step surfaces and positioning holes, it can be easily combined and expanded with other modules or components to achieve customization and multifunctionality of the tooling.

[0042] Preferably, the number of the lock hook fixing plate locating pins 31 is two, and the two lock hook fixing plate locating pins 31 are arranged at intervals along the length direction of the lock hook fixing plate 300. The two lock hook fixing plate locating pins 31 are arranged at intervals along the length direction of the lock hook fixing plate 300. This arrangement can effectively prevent the lock hook fixing plate from being offset or rotated during installation or use. It is conceivable that a fastening device (such as a nut, a bolt, etc.) can be used to fix the locating pins on the lock hook fixing plate to further improve the stability and reliability of the connection.

[0043] In the present invention, the limiting assembly includes a side stopper 41 and a lower stopper 42 . The side stopper 41 is hooked on one side of the enclosure 100 , and the other side perpendicular to the one side of the enclosure 100 is in contact with the lower stopper 42 .

[0044] The structure of the side block 41 is designed to be able to firmly hook on the edge of one side of the enclosure 100 to achieve the positioning of the tooling on the enclosure 100 in the x-axis direction. The lower block 42 is tightly attached to the other side edge that is perpendicular to one side of the enclosure 100 to achieve the positioning of the tooling on the enclosure 100 in the y-axis direction. The structure of the side block 41 and the lower block 42 is relatively simple and easy to install and disassemble. They are usually made of high-strength, corrosion-resistant materials and have a long service life and low maintenance costs.

[0045] Furthermore, two side blocks 41 are provided, and the two side blocks 41 are spaced apart and arranged near the two ends of the tooling body 1 along the length direction of the tooling body 1. The design of multiple side blocks 41 increases the positioning points of the tooling body 1 on the enclosure 100, and the positions and spacings of the two side blocks 41 on the tooling body 1 can ensure that the tooling body 1 maintains an accurate position on the enclosure 100 and is not easily offset.

[0046] Preferably, the mounting groove includes a first mounting groove 12 and a second mounting groove 13 for installing the side block 41 and a third mounting groove 14 for installing the lower block 42. The first mounting groove 12 and the second mounting groove 13 are spaced apart on one side of the long side of the tooling body 1, and the third mounting groove 14 is arranged on one side of the short side that is perpendicular to the long side of the tooling body 1, which effectively enhances the stability and positioning accuracy of the tooling body 1 on the enclosure 100.
