Description

Technical Field

[0001] This utility model relates to the technical field of tooling for welding instrument HUD covers, specifically a welding tooling for instrument HUD covers. Background Technology

[0002] As is well known, the traditional instrument manufacturing industry, especially in processes involving the assembly and welding of head-up display (HUD) covers onto instruments, often faces a series of technical challenges. Without specialized tooling, workers must manually position the HUD cover onto the instrument and temporarily secure it with clamps. This method is prone to inaccurate positioning, especially when aligning specific points; manual operation struggles to guarantee consistent precision each time. During welding, to ensure weld quality, the welding area needs to be treated from multiple angles. However, traditional fixed tooling cannot easily adjust angles, limiting the welding range, increasing welding difficulty, and potentially leading to incomplete welding in certain areas. Therefore, it is necessary to propose solutions to this technical problem. Utility Model Content

[0022] 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.

[0023] Please see Figure 1-4This utility model relates to a welding fixture for an instrument HUD cover, comprising a workbench 1, a lifting mechanism 2 and a bearing seat 3 on the workbench 1, a clamping ring 4 on the bearing seat 3, an adjustment groove at the top of the workbench 1, a toothed ring 5 between the bottom end of the clamping ring 4 and the adjustment groove, a fastening box 6 on one side of the workbench 1, a fastening hole between the fastening box 6 and the adjustment groove, a fastening post 7 on the fastening hole, a toothed block 8 at one end of the fastening post 7, the toothed block 8 engaging with the toothed ring 5, a fastening groove on one side of the fastening hole, and an iron plate 9 on one side of the fastening groove. A magnet 10 is provided between the fastening groove and the fastening column 7. A clamping mechanism is provided on the clamping ring 4. A first bearing 11 is provided at the output end of the lifting mechanism 2. An adjusting plate 12 is provided on the first bearing 11. A second bearing 13 is provided at the bottom end of the adjusting plate 12. A fixed box 14 is provided at the bottom end of the second bearing 13. An elastic support mechanism is provided on the fixed box 14. In this embodiment, the operator clamps the instrument workpiece using the clamping mechanism of the clamping ring 4. The angle position of the fastening box 6 on the adjusting plate 12 can be adjusted by the first bearing 11, making it easy to align the fixed box 14 with the instrument workpiece. Then, the instrument is covered with a HUD. The workpiece is placed at a designated position on the instrument workpiece. Then, the adjusting plate 12 is raised and lowered by using the output end of the lifting mechanism 2, so that the elastic support mechanism of the fixed box 14 elastically supports the instrument HUD cover workpiece. Then, the personnel use welding equipment to perform welding operations. When welding the instrument HUD cover workpiece at different angles around the perimeter is required, the personnel pull the fastening column 7 of the fastening box 6. The fastening column 7 drives the toothed block 8 to move away from the toothed ring 5, so that the magnet 10 moves away from one side of the iron sheet 9. Then, the angle of the clamping ring 4 is rotated by the bearing seat 3, so that the instrument and the instrument HUD cover workpiece rotate by an angle, which is controlled by the second bearing 13. The fixed box 14 can rotate with the HUD cover workpiece. When the fastening column 7 is loosened, the magnetic attraction of the magnet 10 to the iron plate 9 will cause the magnet 10 to abut against the iron plate 9. At this time, the fastening column 7 drives the toothed block 8 to move, and the toothed block 8 engages with the toothed ring 5, which can ensure the stable rotation of the HUD cover workpiece. This makes it convenient for personnel to perform welding operations on different positions around the HUD cover workpiece. This structure can flexibly adjust the angle of the HUD cover workpiece during welding, which is convenient for welding operations on different positions of the HUD cover workpiece. The welding equipment used in this structure is existing technology and will not be described in detail in this structure.

[0024] In this solution, the clamping mechanism includes a clamping groove and an arc plate 15. The clamping groove is formed on both sides of the inner wall of the clamping ring 4. A threaded hole is provided between the clamping groove and the outer side of the clamping ring 4. A threaded post 16 is provided on the threaded hole. A third bearing is provided at one end of the threaded post 16. A clamping post 17 is provided between the third bearing and the clamping groove. The arc plate 15 is installed at one end of the clamping post 17. By rotating the threaded post 16 in the threaded hole, the threaded post 16 drives the third bearing to rotate and move. With the third bearing and the clamping post 17 located in the clamping groove, the clamping post 17 can move linearly in the clamping groove, thereby causing the clamping post 17 to drive the arc plate 15 to move linearly. The arc plate 15 of the two clamping posts 17 can stably clamp the instrument workpiece.

[0025] In this solution, the elastic support mechanism includes a support groove and a support plate 18. The support groove is located inside the fixed box 14, and a support hole is provided at the bottom end of the support groove. An elastic component 19 is provided on the support groove. A support column 20 is provided between the support plate 18 and the support hole. A limiting plate 21 is provided between the support column 20 and the support groove. The limiting plate 21 is elastically supported by the elastic component 19 in the support groove, thereby providing elastic support for the support column 20 and the support plate 18. This facilitates the support plate 18 to rest against the instrument HUD cover workpiece, ensuring that the instrument HUD cover workpiece is stably positioned on the instrument workpiece, and facilitating welding operations by personnel using welding equipment.

[0026] In this design, the bottom of the support plate 18 is provided with a rubber pad, which can stably support the HUD cover of the instrument.

[0027] In this design, a handle 22 is provided on one side of the support column 20, which makes it easy for personnel to lift and use the support column 20 by holding the handle 22.

[0028] In this solution, there are two fastening grooves arranged symmetrically, which can achieve better fixation of the fastening column 7.

[0029] In this solution, the lifting mechanism 2 is an electric telescopic rod, which has the characteristic of high movement accuracy, thereby improving the lifting and moving accuracy of the adjusting plate 12.

[0030] In this design, the arc plate 15 is provided with an anti-slip pad, which can improve the anti-slip performance of the arc plate 15.

[0031] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
