[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 3 A modular tooling for welding an automobile chassis frame in this embodiment includes a base frame 1 and a support base 2. The inner side of the support base 2 is provided with a fixing component for fixing the chassis.

[0023] Please see Figure 1 In this embodiment, the fixing component includes a first motor 3 fixedly connected to the inner side of the support base 2, a threaded rod 4 fixedly connected to the output shaft of the first motor 3, a threaded block 5 threadedly connected to the outer side of the threaded rod 4, a slider 6 fixedly connected to the top of the threaded block 5, a movable positioning plate 7 fixedly connected to the top of the slider 6, and a fixed positioning plate 8 fixedly connected to the left side of the top of the support base 2.

[0024] Specifically, a partition 9 is rotatably connected to the outer side of the threaded rod 4, and the partition 9 is fixedly connected between the inner top and bottom walls of the support base 2.

[0025] It should be noted that the main function of the partition plate 9 is to increase the support stiffness of the threaded rod 4, ensure its stability during transmission, avoid vibration or displacement caused by the cantilever structure, and thus ensure the accuracy of the movement of the movable positioning plate 7.

[0026] Specifically, the top of the inner side of the support base 2 is provided with a sliding opening that is compatible with the slider 6.

[0027] Specifically, the left and right sides of the support base 2 are fixedly connected to the connecting frame 10, the inner left and right side walls of the base frame 1 are rotatably connected to the connecting rod 11, the opposite ends of the left and right connecting rod 11 are fixedly connected to the insert block 1101 that is compatible with the connecting frame 10, the inner top wall of the insert block 1101 is rotatably connected to the threaded shaft 12, and the outer side of the threaded shaft 12 is threadedly connected to the locking threaded cylinder 13.

[0028] It should be noted that the design of the connecting frame 10 and the insert block 1101 enables quick positioning and connection between the support base 2 and the base frame 1, providing a structural basis for modular assembly and disassembly. After the insert block 1101 is inserted into the connecting frame 10, it is fixed by a subsequent locking mechanism.

[0029] Specifically, a turn wheel is fixedly connected to the outer side of the threaded shaft 12, the outer wall of the locking threaded cylinder 13 is square, and guide plates 14 are fixedly connected to both the left and right sides of the locking threaded cylinder 13. A guide shaft 15 is slidably connected to the inner side of the guide plate 14, and the guide shaft 15 is fixedly connected between the inner top and bottom walls of the insert block 1101.

[0030] Specifically, the bottom of the inner side of the insert block 1101 is provided with a through-hole that is compatible with the locking threaded cylinder 13, and the bottom of the inner side of the connecting frame 10 is provided with a locking port that is compatible with the locking threaded cylinder 13, and the through-hole is connected to the corresponding locking port.

[0031] Specifically, a second motor 16 is fixedly connected to the right side of the base frame 1. A transmission rod 17 is fixedly connected to the output shaft of the second motor 16. A transmission wheel 18 is fixedly connected to the left end of the transmission rod 17. A transmission belt 19 is connected to the outer surface of the transmission wheel 18. A driven wheel 20 is connected to the top end of the transmission belt 19. The driven wheel 20 is fixedly connected to the outside of the right connecting rod 11.

[0032] It should be noted that this design allows the support base 2 to be flipped, thereby adjusting the workpiece to the most favorable position for welding, thus assisting welding.

[0033] The working principle of the above embodiments is as follows:

[0034] Place the car chassis frame workpiece on top of the support base 2, with one side of it close to the fixed positioning plate 8. Start the first motor 3, and the output shaft of the first motor 3 drives the threaded rod 4 to rotate. The threaded block 5, which is threaded with the threaded rod 4, will then be horizontally displaced. The threaded block 5 will drive the movable positioning plate 7 to move towards the fixed positioning plate 8 through the slider 6, until the workpiece is firmly clamped between the movable positioning plate 7 and the fixed positioning plate 8.

[0035] When it is necessary to replace or maintain the support base 2, the actuating wheel must first be manually rotated. The actuating wheel drives the threaded shaft 12 to rotate. Due to the sliding fit constraint between the square outer wall of the locking threaded cylinder 13 and the guide plate 14 and guide shaft 15, it cannot rotate on its own. It can only move linearly upward along the guide shaft 15 under the influence of the threaded side, so that its lower end completely exits from the locking hole at the bottom of the connecting frame 10, releasing the lock between the insert block 1101 and the connecting frame 10, thereby releasing the connection between the support base 2 and the base frame 1.

[0036] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.

[0037] It should be noted that the orientations or positional relationships indicated herein are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the purpose of facilitating the description of this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0038] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
