[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limiting this invention.

[0021] In the description of this invention, "several" means one or more, "more than" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0022] Reference Figures 1-10 As shown, the present invention provides a technical solution for a special tooling for assembling T-shaped plates and rib plates: A special tooling for assembling T-shaped plates and rib plates includes several T-shaped plate positioning components 1 arranged laterally, and several rib plate positioning components 2 arranged laterally on one side of the arrangement direction of the T-shaped plate positioning components 1.

[0023] It should be further explained that the T-shaped plate positioning assembly 1 includes an I-shaped top rail 11, with several T-shaped plate positioning trolleys 6 slidably connected to the top of the I-shaped top rail 11; the rib plate positioning assembly 2 includes an I-shaped top rail 22, with several rib plate positioning trolleys 5 slidably connected to the top of the I-shaped top rail 22, and the I-shaped top rail 22 can slide in the arrangement direction of the rib plate positioning assembly 2; the T-shaped plate positioning trolleys 6 include a slider 3 61 slidably connected to the top of the I-shaped top rail 11, with two side clamping plates 3 62 symmetrically arranged on the top surface of the slider 3 61, and a gap between the two side clamping plates 3 62 for positioning the T-shaped plate workpiece 4. The length direction is the same as the arrangement direction of the T-shaped plate positioning assembly 1; the rib positioning trolley 5 includes a slider 2 51 slidably connected to the top of the I-shaped top rail 22. Side clamping plates 1 52 and 2 53 are symmetrically arranged on both sides of the top surface of slider 2 51. There is a gap between side clamping plates 1 52 and 2 53 for positioning the rib workpiece 3. The length direction of the rib workpiece 3 is perpendicular to the arrangement direction of the rib positioning assembly 2; several butt joints are opened at the bottom of the rib workpiece 3 along its length direction. The T-shaped plate workpiece 4 slides from the same row of T-shaped plate positioning trolleys 6 on several T-shaped plate positioning assemblies 1 to the corresponding butt joint on the rib workpiece 3.

[0024] Working principle: When using this fixture, firstly, fix several T-plate positioning components 1 and rib plate positioning components 2 on the work site. According to the assembly requirements of rib plate workpieces 3 and T-plate workpieces 4, slide the I-shaped top rail 22 to adjust the distance between several rib plate workpieces 3. Insert the rib plate workpiece 3 into the gap between the side clamping plates 52 and 53 on the slider 21. According to the position of the butt joint gap on the rib plate workpiece 3, slide the slider 21 to adjust the position of the rib plate positioning trolley 5 on the I-shaped top rail 22, so that the butt joint gap on the rib plate workpiece 3 is located on both sides of the top surface of the slider 21. Between the first clamping plate 52 or the second side clamping plate 53, the position of the T-shaped plate positioning trolley 6 on the top rail 11 of the I-shaped plate is adjusted, that is, the sliding slider 61 is slidable so that the gap between the two side clamping plates 62 on the top surface of the slider 61 is aligned with the butt joint gap on the rib plate workpiece 3. At this time, the worker inserts the T-shaped plate workpiece 4 into the gap between the two side clamping plates 62 and pushes the T-shaped plate workpiece 4 along the arrangement direction of the T-shaped plate positioning component 1 or the rib plate positioning component 2, so that the T-shaped plate workpiece 4 can be inserted into the butt joint gap on the rib plate workpiece 3, thus efficiently completing the assembly of the rib plate workpiece 3 and the T-shaped plate workpiece 4.

[0025] This fixture, through the setup and collaborative operation of T-plate positioning assembly 1, rib positioning assembly 2, T-plate positioning trolley 6, and rib positioning trolley 5, utilizes the T-plate workpiece 4, which is positioned on T-plate positioning assembly 1, to quickly insert into the mating gap on rib workpiece 3, which is positioned on rib positioning assembly 2. This ensures assembly accuracy while greatly improving the assembly efficiency of rib workpiece 3 and T-plate workpiece 4. It can adapt to different specifications of rib workpiece 3 and T-plate workpiece 4 and their assembly requirements. The fixture is safe and reliable, with modular components that are easy to disassemble and assemble, reducing the steps required for workers to change fixtures and greatly improving the production cycle of rib workpiece 3 and T-plate workpiece 4 assembly.

[0026] Reference Figures 1-10 As shown, in an optional embodiment, the T-shaped plate positioning assembly 1 further includes several support members 13 disposed on the bottom surface of the I-shaped top rail 11. Side baffles 12 are provided at both ends of the top surface of the I-shaped top rail 11 along its length to limit the T-shaped plate positioning trolley 6. It should be noted that when using this fixture, the support members 13 are fixed to the work site, providing stable support to the I-shaped top rail 11 and ensuring its stability when carrying the T-shaped plate workpiece 4, preventing deformation or displacement due to excessive load. The side baffles 12 further enhance the sliding safety of the T-shaped plate positioning trolley 6 on the I-shaped top rail 11, preventing it from falling off during operation and improving the smoothness of the assembly process.

[0027] Reference Figures 1-10As shown, in an optional embodiment, the bottom surface of the rib positioning assembly 2 is provided with several sliding mechanisms. It should be noted that the sliding mechanism enables the I-shaped top rail 22 to slide in the arrangement direction of the rib positioning assembly 2, thereby facilitating the operator to adjust the distance between different rib workpieces 3 according to actual needs, making the tooling more applicable and versatile.

[0028] Reference Figures 1-10 As shown, in an optional embodiment: the sliding mechanism includes an I-shaped bottom rail 21, with a slider 23 slidably connected to the top of the I-shaped bottom rail 21. The length direction of the I-shaped bottom rail 21 is the same as the arrangement direction of the rib positioning assembly 2. Side baffles 2101 are provided at both ends of the top surface of the I-shaped bottom rail 21 along its length direction. The slider 23 is fixedly connected to the bottom surface of the I-shaped top rail 22. It should be noted that this sliding mechanism can ensure the stability and accuracy of the rib positioning assembly 2 during movement, avoiding positional displacement caused by external forces or vibrations. The cooperation between the I-shaped bottom rail 21 and the slider 23 not only improves the load-bearing capacity of the overall structure, but also further enhances the limiting function through the setting of the side baffles 2101. In addition, this setting makes it easy for workers to adjust the spacing between the rib positioning assemblies 2 according to actual needs, improving the adaptability and flexibility of this tooling, and making it suitable for the assembly needs of rib workpieces 3 and T-shaped plate workpieces 4 of different specifications.

[0029] Reference Figures 1-10 As shown, in an optional embodiment, the sliding mechanism includes an inverted T-shaped bottom rail 24 and a connecting plate 25. The connecting plate 25 is fixedly connected to the bottom surface of the I-shaped top rail 22. A rollable V-shaped roller 2501 is provided at the bottom of the connecting plate 25. The V-shaped roller 2501 rolls on the inverted T-shaped bottom rail 24, and the length direction of the inverted T-shaped bottom rail 24 is the same as the arrangement direction of the rib positioning assembly 2. It should be noted that when using this fixture, the arrangement of the T-shaped bottom rail 24, the V-shaped roller 2501, and the connecting plate 25 enables the rib positioning assembly 2 to move more smoothly and linearly, reducing the friction when the I-shaped top rail 22 slides towards the arrangement direction of the rib positioning assembly 2, thus facilitating operation.

[0030] Reference Figures 1-10 As shown, in an optional embodiment, each of the two side clamping plates 62 has a top arc plate 6201 on its top, and both top arc plates 6201 bend downward toward the gap between the two side clamping plates 62. It should be noted that the arrangement of the two top arc plates 6201 can effectively guide the T-shaped plate workpiece 4 to enter the gap between the two side clamping plates 62 more smoothly, reducing friction or jamming caused by direct contact.

[0031] Reference Figures 1-10As shown, in an optional embodiment: Side positioning plates 6202 are provided on the outer sides of both side clamping plates 62. One side positioning plate 6202 has an inner side connected to a stop block 63 via a pad 6302. The other side positioning plate 6202 is threadedly connected to a threaded rod 64. A stop block 63 is also provided at the inward-facing end of the threaded rod 64. A rollable ball bearing 6301 is provided at the end of the stop block 63 facing the gap between the two side clamping plates 62. Bearing seats 65 are provided on both sides of the gap between the two side clamping plates 62 at the top of the slider 61. A roller 6501 is rotatably connected between the two bearing seats 65. It should be noted that when using this fixture, the operator can adjust the threaded rod 64 to allow the stop block 63 to apply appropriate clamping force to T-shaped plate workpieces 4 of different thicknesses, ensuring stability during assembly. The design of ball bearing 6301 effectively reduces friction, allowing the T-shaped workpiece 4 to slide smoothly in the gap between the two side clamping plates 62, ensuring accurate positioning. Furthermore, the installation of roller 6501 further enhances the smoothness of the movement of the T-shaped workpiece 4, preventing positional misalignment or wear caused by friction.

[0032] Reference Figures 1-10 As shown, in an optional embodiment: Bearing seats 55 are provided on both sides of the top surface of slider 2 51, and a roller 5501 is rotatably connected between the two bearing seats 55. A threaded rod 54 is threaded onto the side clamping plate 52, facing the gap between side clamping plate 52 and side clamping plate 2 53. A stop block 5401 is provided at the inward end of the threaded rod 54, and a rolling ball is provided at the inward end of the stop block 5401. A nut 5601 is provided on one side of the top surface of slider 2 51, and a bolt 56 is threaded onto the nut 5601, which can pass through the top surface of slider 2 51, for positioning the rib positioning carriage 5 on the I-shaped top rail 2 22. It should be noted that when using this fixture, the operator can rotate the threaded rod 54 to move the stop block 5401, thereby changing the size of the gap between side clamping plate 52 and side clamping plate 2 53 to accommodate rib workpieces 3 of different thicknesses. Furthermore, due to the presence of the ball bearings, the friction is significantly reduced when the rib plate workpiece 3 is inserted into the gap between the first side clamping plate 52 and the second side clamping plate 53. This not only improves work efficiency but also reduces the risk of surface damage to the rib plate workpiece 3.

[0033] Reference Figures 1-10As shown, in an optional embodiment, it further includes a T-shaped plate lifting and fine-tuning trolley 7, which is located directly below the T-shaped plate workpiece 4. The T-shaped plate lifting and fine-tuning trolley 7 includes a liftable lifting platform 71. Bearing seats 72 are provided on both sides of the top surface of the lifting platform 71. A roller 7201 is rotatably connected between the two bearing seats 72. The bottom surface of the T-shaped plate workpiece 4 slides on the roller 7201. It should be noted that when using this tooling, because the ground of the installation site (work site) is not completely level, the T-shaped plate workpiece 4 cannot be horizontally positioned on the T-shaped plate positioning component 1. This causes interference when the T-shaped plate workpiece 4 slides towards the corresponding mating gap on the rib workpiece 3. Therefore, by setting up the T-shaped plate lifting fine-tuning trolley 7 and controlling the lifting of the lifting plate 71, the T-shaped plate workpiece 4 is kept horizontal and slides more smoothly towards the corresponding mating gap on the rib workpiece 3. The controllable lifting of the lifting plate 71 can be controlled by an electric push rod, which is existing technology and will not be elaborated on here. The setting of bearing seat 3 72 and roller 3 7201 makes the resistance of the T-shaped plate workpiece 4 sliding on roller 3 7201 less and smoother, which is convenient for team operation.

[0034] Reference Figures 1-10 As shown, in an optional embodiment, the top surface of the I-shaped top rail 22 is provided with side baffles 2201 at both ends along its length to limit the rib positioning trolley 5. It should be noted that the side baffles 2201 prevent the rib positioning trolley 5 from falling off the I-shaped top rail 22, thereby improving the stability of the rib positioning trolley 5 during movement and positioning.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
