Description

Technical Field

[0001] This utility model relates to the field of assembly tooling technology, specifically to a fixture tooling for Formula One racing cars. Background Technology

[0002] Formula Student car frames are typically truss structures, welded together from several tubing sections of varying lengths. During the welding process, specialized clamps are required to hold the tubing in place, ensuring the frame's geometric accuracy and the quality of the welds.

[0003] In Formula One racing car fixture manufacturing, traditional methods require directly machining inclined positioning holes into the steel plate to fix the positioning rod at a specific angle. This process demands extremely high precision in processing equipment, technology, and operation. It is not only complex and time-consuming, but also highly susceptible to errors in the positioning hole's position, perpendicularity, or angle due to machining deviations. These manufacturing errors directly translate into positioning errors in the fixture, causing inaccuracies in the spatial coordinates of the clamping device and severely affecting the symmetry and geometric accuracy of the racing car frame welding. Furthermore, the high difficulty of machining increases manufacturing costs and timelines, and a machining error can render the entire steel plate unusable, directly weakening the fixture's overall reliability, reusability, and long-term economic viability.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the above-mentioned problems and provide a fixture for Formula One racing cars.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a fixture for Formula One racing cars, characterized in that it includes: The frame is made up of several aluminum square tubes of different lengths connected together; The main body of the racing car frame is connected to the skeleton; Multiple fixed structures are connected to the frame, including a pair of I-beams connected to the frame, on which steel plates one, two, three, and four are fixedly connected. A pair of positioning rods one are connected to steel plates one and two, and several positioning rods two are connected to steel plates three and four. Each positioning rod one and positioning rod two is connected to a clamping device.

[0007] The skeleton includes several second connecting pipes connected to a pair of first connecting pipes, and several third, fourth and fifth connecting pipes of different lengths connected to the second connecting pipes.

[0008] A limiting plate is fixedly connected to the fifth connecting pipe, and a pair of limiting grooves are opened on the limiting plate to limit the racing car frame body.

[0009] Several steel plates are also fixedly connected to several of the positioning rods.

[0010] Positioning holes are provided on steel plates one, two, three, four and five. An insert is fixedly connected to each positioning hole, and positioning rod one and positioning rod two are respectively fixedly connected to the inserts of the corresponding positioning holes.

[0011] The clamping device includes a pair of frame lugs that clamp onto the racing car frame body, and the two frame lugs are connected by a fisheye joint ball joint.

[0012] The advantages of this utility model compared with the prior art are as follows: The aforementioned problems are effectively solved by innovatively employing 3D-printed insert technology. Custom inserts are installed in pre-drilled positioning holes in the steel plate, and the through-holes of the inserts can be precisely designed with an inclined angle as needed. This method avoids the difficult and costly direct inclined drilling, significantly reducing reliance on traditional processing techniques and lowering manufacturing barriers. 3D printing technology endows this design with high flexibility and precision, enabling the rapid fabrication of complex irregular hole shapes. This not only improves production efficiency and ensures positioning consistency but also facilitates later maintenance and replacement, significantly enhancing the adaptability and economy of the tooling.

[0016] 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.

[0017] Example 1: like Figure 1 As shown in Figure 4, this utility model provides a fixture for Formula One racing cars, including a frame 1.

[0018] The frame 1 is composed of several aluminum square tubes of varying lengths. Specifically, the frame 1 is based on a pair of the longest first connecting tubes 11. Several second connecting tubes 12 are mounted on the tops of the two first connecting tubes 11, forming the main horizontal support layer. The second connecting tubes 12 are fixedly connected to each other using triangular iron fittings. Finally, the tops of the several second connecting tubes 12 are respectively connected to third connecting tubes 13 and fourth connecting tubes 14 of varying lengths, as well as a pair of fifth connecting tubes 15. The third connecting tubes 13, fourth connecting tubes 14, and fifth connecting tubes 15 are vertically installed on the tops of the several second connecting tubes 12 in a combination of lengths, and are also rigidly connected using triangular iron fittings, ultimately forming a frame as shown in the image. Figure 2 The stable space truss structure shown.

[0019] Then, the upper part of the front end of the two fifth connecting pipes 15 is fixedly connected to the limiting plate 16. The limiting plate 16 has a pair of limiting grooves 17 on both sides of the top end for limiting the racing car frame body.

[0020] One side of the frame 1 is also connected to several fixed structures 2, including a pair of I-beam steel pipes 3, which are arranged in front and behind, with their bottom ends connected to the top of the corresponding second connecting pipe 12, and are also fixedly connected to the top of the second connecting pipe 12 by triangular iron connectors.

[0021] Steel plate 14 is fixedly connected to the top ends of the two second connecting pipes 12; steel plate 25 is fixedly connected to the lower part of the two second connecting pipes 12 on their adjacent sides; steel plate 36 and steel plate 47 are fixedly connected to the opposite sides of the two second connecting pipes 12, with steel plate 36 located behind steel plate 47. Next, a pair of positioning rods 18 are fixedly connected to both steel plate 14 and steel plate 25, arranged in a front-to-back pattern. Simultaneously, several positioning rods 29 are fixedly connected to both steel plate 36 and steel plate 47. In this embodiment, there are two positioning rods 29 on steel plate 36 and one positioning rod 29 on steel plate 47.

[0022] Furthermore, in order to better secure the three positioning rods 29, a steel plate 518 is fixedly connected to the surface of the three positioning rods 29.

[0023] In addition, clamping devices 10 are connected to both positioning rod 8 and positioning rod 9. The two clamping devices 10 located on positioning rod 8 are positioned between steel plate 4 and steel plate 5.

[0024] The clamping device 10 includes a pair of frame lugs 20 slidably connected to the outer surface of positioning rod 8 or positioning rod 9; the clamping device 10 also includes a fisheye joint ball joint 21 slidably connected to the outer surface of positioning rod 8 or positioning rod 9, and a pitch-changing washer is fixedly connected to the adjacent sides of each pair of frame lugs 20, the pitch-changing washer being fixedly connected to the fisheye joint ball joint 21. It should be noted that the pitch-changing washer is made of elastic material, model DIN6796. Therefore, when the fisheye joint ball joint 21 is rotated, it will cause the two frame lugs 20 to rotate together.

[0025] Example 2: It should be noted that positioning rod 8 is fixedly connected at an angle to steel plate 4 and steel plate 5; similarly, positioning rod 9 is also fixedly connected at an angle to steel plate 6 or steel plate 7. Therefore, during initial processing, it is necessary to drill holes at an angle in steel plates 4 and 5, as well as steel plates 6 and 7, and then insert the corresponding positioning rods 8 or 9. However, drilling at an angle places higher demands on the drilling process and tools; otherwise, the drilling accuracy will be reduced. To solve this problem, Embodiment Two is proposed.

[0026] Quadrilateral positioning holes are formed on steel plates 4, 5, 6, 7, and 18. In this embodiment, there are two positioning holes on steel plates 4, 5, and 18, and one positioning hole on steel plates 6 and 7. An insert 19 with a through hole is fixedly connected inside the positioning hole. It should be noted that the insert 19 is 3D printed, which requires fewer processing steps than drilling in the prior art, has lower requirements for technology and tools, and is easier to process.

[0027] Finally, positioning rod 8 is fixedly connected to the insert 19 on steel plate 4 and steel plate 5. More specifically, positioning rod 8 is fixedly connected to the through hole of the corresponding insert 19. Positioning rod 9 is fixedly connected to the insert 19 on steel plate 6 and steel plate 7. More specifically, positioning rod 9 is fixedly connected to the through hole of the corresponding insert 19.

[0028] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.

[0029] The detailed description of known functions and components is omitted in this disclosure. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of commercially available instruments.
