[0002] In the field of tooling positioning in automobile manufacturing, the common technical solutions currently include dedicated overall switching platforms and servo NC flexible platforms. However, in practical application scenarios, for requirements that only require switching some tooling on the positioning platform, adopting the overall switching positioning platform approach would result in switching all positioning tooling on the positioning platform, leading to resource waste. For example, in the same vehicle architecture, there are positioning tooling requirements for different body styling parts (such as wheel arch outer panels). If the entire positioning platform is switched, it will not only consume a lot of unnecessary time and costs, but also reduce production efficiency. Utility Model Content

[0034] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0037] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0040] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0041] like Figures 1-10 As shown, a preferred embodiment of the present invention provides a positioning fixture switching device with intersecting first horizontal direction X and second horizontal direction Y. The positioning fixture switching device includes a base platform 1, a positioning platform 2, a first positioning fixture 3, and a second positioning fixture 4.

[0042] The base platform 1 is provided with a guide rail 11 extending along the first horizontal direction X. The positioning platform 2 is movably connected to the guide rail 11 and can move along the guide rail 11. The first positioning fixture 3 is connected to the positioning platform 2 and is used to fix the vehicle body frame. The second positioning fixture 4 is detachably connected to the first positioning fixture 3 and is used to fix the vehicle body styling parts.

[0043] Based on this technical solution, by movably connecting the positioning platform 2 to the guide rail 11 of the base platform 1, when it is necessary to produce a new vehicle architecture (different vehicle architectures have different body frames) through the positioning tooling switching device, the old positioning platform 2 can be moved from the production position to the disassembly position along the guide rail 11. Then, at the disassembly position, the old positioning platform 2 and the first positioning tool 3 and the second positioning tool 4 installed on the old positioning platform 2 can be removed. Then, by assembling the new positioning platform 2 to the installation position of the guide rail 11 and moving the new positioning platform 2 from the installation position to the production position through the guide rail 11, the production of the new vehicle architecture can be carried out through the first positioning tool 3 and the second positioning tool 4 installed on the new positioning platform 2. Therefore, the positioning tooling switching device provided by this utility model can switch between the old positioning platform 2 and the new positioning platform 2 on the base platform 1, so as to be suitable for the production of various vehicle architectures.

[0044] The second positioning fixture 4 is detachably connected to the first positioning fixture 3. When it is necessary to produce vehicles with the same body frame but different styling parts using the positioning fixture switching device, the old second positioning fixture 4 can be removed from the first positioning fixture 3, and the new second positioning fixture 4 can be assembled onto the first positioning fixture 3 to produce different styling parts for vehicles with the same body frame. Therefore, the positioning fixture switching device provided by this utility model does not require a complete switch of the positioning platform 2 during the production of different body styling parts for vehicles with the same body frame, reducing the time required for switching positioning fixtures. Operators only need to quickly disassemble and install the second positioning fixture 4 to complete the replacement of positioning fixtures for different body styling parts for vehicles with the same body frame. This efficient partial fixture switching method can improve production efficiency and enable the production of more products per unit time.

[0045] The first horizontal direction X is perpendicular to the vertical direction Z, and the second horizontal direction Y is perpendicular to the vertical direction Z.

[0046] In this embodiment, the base platform 1 is provided with two guide rails 11.

[0047] In this embodiment, the second positioning fixture 4 is used to fix the body styling part, which is a structural form of the wheel arch outer panel.

[0048] In some other embodiments, the second positioning fixture 4 can also be used to fix any other body styling parts such as doors, bumpers, and fenders, which is not limited here.

[0049] See Figures 3-6The connector 313 provided in this embodiment of the utility model includes a positioning pin 3131; the second positioning fixture 4 includes a connecting plate 41 and a second positioning clamp 42. The connecting plate 41 has a positioning hole 411 for the positioning pin 3131 to be inserted, and the second positioning clamp 42 is connected to the connecting plate 41 and used to fix the body styling parts.

[0050] The use of positioning pins 3131 and matching positioning holes 411 on the connecting plate 41 of the second positioning fixture 4 reduces a large number of unnecessary parts, making the overall structure of the fixture simpler and clearer. At the same time, the simple structure also makes the installation process simpler and easier to understand. Operators can quickly master the installation skills without complicated training and can complete the installation and disassembly of the second positioning fixture 4 in a short time, improving the efficiency of fixture switching.

[0051] The standardized setup of locating pins 3131 and locating holes 411 allows different second positioning fixtures 4 to be used with the same locating pins 3131 on the same positioning mechanism 31, as long as they use the same locating holes 411. This means that when producing different body styling parts for the same vehicle architecture, only different second positioning fixtures 42 need to be designed according to the characteristics of the styling parts and connected to the connecting plate 41 with standard locating holes 411, which can achieve quick tooling change and universality. This setup enhances the universality and interchangeability of the tooling, reduces the manufacturing cost of the tooling, and improves the efficiency of tooling use.

[0052] The first positioning fixture 314 can be any fixture that can be used to fix body styling parts in the prior art, and is not limited here.

[0053] In this embodiment, two second positioning clamps 42 are installed on the connecting plate 41.

[0054] In some other embodiments, the connecting plate 41 may also be equipped with any number of second positioning fixtures 42, such as one, three, four, or five, which is not limited here.

[0055] Multiple connectors 313 are connected to the mounting plate 312, and multiple positioning holes 411 are provided on the connecting plate 41. One positioning pin 3131 passes through one positioning hole 411. This multi-point connection method can enhance the connection stability between the second positioning fixture 4 and the positioning mechanism 31. Compared with single-point connection, multi-point connection can more evenly distribute the external force borne by the fixture when fixing the body styling parts, and can avoid the second positioning fixture 4 and the first positioning fixture 3 from loosening or displacement due to excessive force at a single point.

[0056] The connector 313 also includes a telescopic drive unit 3132; the mounting plate 312 has a through hole 3121; the telescopic drive unit 3132 is located below the mounting plate 312, the telescopic drive unit 3132 is connected to the positioning pin 3131 and is used to drive the positioning pin 3131 through the through hole 3121 and into the positioning hole 411.

[0057] By setting a telescopic drive unit 3132 that controls the extension and retraction of the positioning pin 3131, the extension and retraction of the positioning pin 3131 can be flexibly controlled according to actual production needs. When it is necessary to replace the second positioning fixture 4, the telescopic drive unit 3132 can quickly retract the positioning pin 3131, making it convenient for operators to quickly disassemble the fixture. When installing the new second positioning fixture 4, it can promptly drive the positioning pin 3131 to extend and complete the connection. This flexible control method enables the positioning fixture switching equipment to better adapt to different production rhythms and complex and ever-changing production tasks, improving the overall flexibility and adaptability of the fixture system.

[0058] The telescopic drive unit 3132 can be any device that can drive the positioning pin 3131 to extend or retract, such as a cylinder, motor, or electric push rod, and is not limited here.

[0059] The mounting plate 312 has multiple through holes 3121 and multiple connectors 313, with one connector 313 corresponding to one through hole 3121.

[0060] The positioning mechanism 31 also includes multiple omnidirectional balls 316; the mounting plate 312 has multiple mounting holes 3122, and one omnidirectional ball 316 is installed in one mounting hole 3122. The omnidirectional ball 316 is used to support the connecting plate 41.

[0061] When the second positioning fixture 4 needs to be replaced, the universal ball 316 can provide flexible support for the connecting plate 41 of the second positioning fixture 4, allowing the operator to easily push the connecting plate 41 to realize the rapid movement and adjustment of the second positioning fixture 4 on the positioning mechanism 31. This simplifies the switching process of the second positioning fixture 4, improves the switching efficiency, and meets the need for rapid replacement of the second positioning fixture 4 in the production process. It is especially suitable for production scenarios that require frequent switching of the second positioning fixture 4.

[0062] See Figures 7-10 The positioning tooling switching device provided in this embodiment of the utility model also includes a switching trolley 5, which is used to support and transport the second positioning tooling 4.

[0063] The switching trolley 5 is specifically used to support and transport the second positioning fixture 4, which can improve the transportation speed of the fixture in the production workshop. When it is necessary to replace the second positioning fixture 4, the operator can quickly place the fixture to be replaced on the switching trolley 5 and transport it to the target positioning mechanism 31. Compared with the traditional manual handling method, the switching trolley 5 can complete the long-distance transportation of the fixture in a short time, reduce the waiting time in the fixture switching process, and significantly improve the rhythm of the entire production process. It is especially suitable for production scenarios with large production line layouts and long fixture transportation distances.

[0064] The switching trolley 5 includes a support assembly 51, which includes a support plate 511, multiple support legs 512 and multiple swivel casters 513. The support legs 512 are connected to the lower end of the support plate 511, and each support leg 512 is connected to a swivel caster 513 at its lower end.

[0065] The support plate 511 in the support assembly 51 provides a large and stable bearing platform for the second positioning fixture 4. The universal casters 513 connected to the lower end of each support leg 512 can give the switching trolley 5 high mobility, and the operator can easily push the switching trolley 5 to move within the production workshop.

[0066] The switching trolley 5 also includes multiple limiting components 52, which are spaced apart along the length of the support plate 511. Each limiting component 52 includes a support roller 521, a first limiting member 522, and a second limiting member 523. The support roller 521 is connected to the top of the support plate 511 and is used to support the second positioning fixture 4. The first limiting member 522 is connected to the top of the support plate 511 and is located on one side of the support roller 521. The second limiting member 523 is connected to the top of the support plate 511 and is located on the side of the support roller 521 opposite to the first limiting member 522.

[0067] During transportation, the workshop ground conditions are complex and changeable, and there may be bumps and vibrations. The setting of the limiting component 52 can improve the stability of the switching trolley 5 in transporting the second positioning fixture 4. When the switching trolley 5 encounters bumps, the support roller 521 can rotate flexibly to adapt to the slight displacement of the second positioning fixture 4, while the first limiting component 522 and the second limiting component 523 can quickly prevent the fixture from excessive displacement caused by vibration, so that the fixture is kept in a relatively stable position. The coordinated work of multiple limiting components 52 can reduce the shaking amplitude of the fixture during transportation, ensure the stability of the fixture transportation, and improve the safety and reliability of the entire transportation process.

[0068] In some embodiments, the first limiting member 522 and the second limiting member 523 can be configured to be close to each other and far apart from each other, so that the first limiting member 522 and the second limiting member 523 can be adapted to the limiting of the second positioning fixture 4 of various sizes on the support plate 511.

[0069] When it is necessary to assemble the second positioning fixture 4 of the switching trolley 5 onto the first positioning fixture 3 of the positioning mechanism 31, the length direction of the support plate 511 is parallel to the first horizontal direction X, and then the second positioning fixture 4 of the switching trolley 5 is pushed onto the first positioning fixture 3.

[0070] The switching trolley 5 also includes an X-shaped telescopic deformation assembly 53; there are two support assemblies 51, namely the first support assembly 51A and the second support assembly 51B; the X-shaped telescopic deformation assembly 53 includes a first connecting rod 531, a second connecting rod 532, a rotating shaft 533, a first slide rail 534, and a second slide rail 535; the first connecting rod 531 and the second connecting rod 532 are arranged crosswise, and the rotating shaft 533 is located at the intersection of the first connecting rod 531 and the second connecting rod 532, so that the first connecting rod 531 can rotate around the rotating shaft 533 and the second connecting rod 532 can rotate around the rotating shaft 534. The connecting rod 532 is rotatable around the pivot 533; the first slide rail 534 is connected to the support plate 511 of the first support assembly 51A, and the second slide rail 535 is connected to the support plate 511 of the second support assembly 51B; one end of the first connecting rod is slidably connected to the first slide rail 534 and can slide along the first slide rail 534, and the other end is slidably connected to the second slide rail 535 and can slide along the second slide rail 535; one end of the second connecting rod is slidably connected to the first slide rail 534 and can slide along the first slide rail 534, and the other end is slidably connected to the second slide rail 535 and can slide along the second slide rail 535.

[0071] The X-shaped telescopic deformation component 53 allows for flexible adjustment of the distance between the two support components 51 (first support component 51A and second support component 51B). The distance between the two support plates 511 can be increased or decreased by the rotation of the first connecting rod 531 and the second connecting rod 532 around the pivot 533 and their sliding on the first slide rail 534 and the second slide rail 535. When the positioning tooling switching device needs to replace different second positioning tools 4 on the two positioning mechanisms 31, the X-shaped telescopic deformation component can adjust the distance between the two support components 51. This allows the second positioning tool 4 carried on the switching trolley 5 to quickly and accurately match the installation position of the second positioning tool 4 on the positioning mechanism 31. For example, in the production process of different body styling parts of the same vehicle architecture, the layout of the second positioning tool 4 on the positioning mechanism 31 differs due to the differences in styling parts. The switching trolley 5 can adjust the support distance to make the second positioning tool 4 carried by the switching trolley 5 fit the installation position of the second positioning tool 4 on the positioning mechanism 31, thereby improving the success rate and efficiency of switching the second positioning tool 4 between the switching trolley 5 and the positioning mechanism 31.

[0072] Within the production workshop, transportation routes may face space constraints or require bypassing obstacles. The X-shaped telescopic deformation component enables the switching trolley 5 to flexibly change its structural dimensions. When encountering narrow passages or needing to avoid large equipment, operators can control the X-shaped component to reduce the distance between the two support components 51, allowing the switching trolley 5 to pass smoothly. During non-full-load transportation, the X-shaped telescopic deformation component can be used to reduce the distance between the two support components 51, reducing the space occupied by the switching trolley 5. This is particularly important for production environments with limited workshop space and dense equipment, effectively avoiding space waste caused by excessively large transportation equipment, making the spatial layout within the workshop more rational, improving overall space utilization, and contributing to improved logistics efficiency on the production site.

[0073] In this embodiment, a limiting component 52 includes two support rollers 521. The two support rollers 521 are spaced apart along the width direction of the support plate 511.

[0074] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
