Description

Technical Field

[0001] This utility model relates to the technical field of flywheel processing, specifically to a welding station for processing automobile flywheels. Background Technology

[0002] The flywheel welding process is a key step in ensuring the structural strength and assembly accuracy of the flywheel. The welding table, as the core tooling of this process, plays a decisive role in production efficiency and product quality due to its rational design.

[0003] Currently, commonly used flywheel welding stations in the industry generally suffer from the following problems: 1. Traditional welding stations are mostly single-station or dual-station designs, capable of fixing and welding only 1-2 flywheels at a time. Under the large-scale production demands of the automotive manufacturing industry, this design cannot meet the processing cycle of large batches of flywheels, resulting in limited overall production line efficiency. 2. Existing welding station limiting mechanisms mostly adopt simple clamping methods, relying solely on lateral mechanical extrusion for fixation. Due to the positioning requirements of the flywheel structure's central hole and circumferential mounting holes, traditional clamps cannot accurately position these two critical locations simultaneously, easily leading to flywheel misalignment during welding. This results in flywheel end face runout, mounting hole position deviations, and other problems, affecting subsequent assembly accuracy and product consistency. Summary of the Invention

[0004] The purpose of this invention is to provide a welding station for processing automobile flywheels, so as to overcome the above-mentioned defects in the prior art.

[0005] A welding table for processing automobile flywheels includes a worktable and a multi-hole positioning mechanism. The top of the worktable is provided with a fixed plate via a fixed base. The top of the fixed plate is provided with a positioning plate. A plurality of positioning grooves for placing flywheels are evenly distributed along the circumference of the positioning plate. The multi-hole positioning mechanism is provided on the fixed plate and the worktable and is used to fix multiple flywheels simultaneously.

[0006] Preferably, the fixed plate is provided with a support seat in each limiting groove, and the support seat is provided with a plurality of positioning rods that are inserted into the mounting holes on the flywheel.

[0007] Preferably, the multi-hole positioning mechanism includes a connecting ring, elastic expansion plates, a cylinder, and an expansion rod. A connecting ring is installed at the center of each support base, and several elastic expansion plates are evenly distributed along the inner circumference of the connecting ring. The inner wall of the elastic expansion plate is provided with a pressing slope. The cylinder is installed at the bottom of the worktable, and a movable frame is provided at the upper end of its piston rod. An expansion rod corresponding to each support base is provided on the movable frame. The expansion rod is inserted into the fixed plate, support base, connecting ring, and elastic expansion plates.

[0008] Preferably, the upper end of the expansion rod has a tapered structure.

[0009] Preferably, the movable frame includes a movable disk and a connecting plate, the upper end of the piston rod of the cylinder is connected to the movable disk, and a connecting plate connected to the expansion rod is provided along the outer circumference of the movable disk.

[0010] Preferably, the support base is connected to the fixed plate by bolts.

[0011] Preferably, the limiting groove is a semi-circular structure that cooperates with the flywheel.

[0012] The beneficial effects achieved by this utility model are as follows:

[0013] 1. The welding station of this application realizes the function of placing flywheels at multiple stations simultaneously by evenly distributing several limiting grooves around the circumference of the limiting plate. This breaks the processing limitations of traditional single or double stations. Combined with the multi-hole limiting mechanism for the synchronous fixing of multiple flywheels, the operator can complete the positioning and fixing of multiple flywheels at one time, which greatly reduces the welding preparation time of a single batch of flywheels and significantly improves the overall processing cycle of the production line. It can fully adapt to the large-scale production needs of the automotive manufacturing industry.

[0014] 2. In this application, on the one hand, the positioning rod on the support can be inserted into the circumferential mounting hole of the flywheel to limit the circumferential position of the flywheel; on the other hand, the elastic expansion plate is inserted into the center hole of the flywheel, and the tapered structure of the expansion rod achieves coaxial positioning and fixation of the center hole. This dual positioning method constrains the flywheel from two key dimensions, circumferential and radial, effectively avoiding the displacement or shaking of the flywheel during the welding process and reducing the scrap rate caused by positioning deviation.

[0025] like Figure 1-6 As shown, this utility model provides a welding table for processing automobile flywheels, including a worktable 1 and a multi-hole positioning mechanism 5. The top of the worktable 1 is provided with a fixed plate 3 via a fixed base 2. The top of the fixed plate 3 is provided with a positioning plate 4. A plurality of positioning grooves 41 for placing flywheels 6 are evenly distributed along the circumference of the positioning plate 4. The positioning grooves 41 are semi-circular structures that cooperate with the flywheels 6.

[0026] In addition, each of the fixed plates 3 is provided with a support seat 31 connected by bolts in each limiting groove 41, which can facilitate the disassembly and assembly of the support seat 31. The support seat 31 is provided with a number of positioning rods 32 that are inserted into the mounting holes on the flywheel 6. The positioning rods 32 can be inserted into the circumferential mounting holes of the flywheel 6 to limit the circumferential position of the flywheel 6.

[0027] In addition, the multi-hole position limiting mechanism 5 is set on the fixed plate 3 and the worktable 1 and is used to fix multiple flywheels 6 at the same time. The multi-hole position limiting mechanism 5 includes a connecting ring 51, elastic expansion plates 52, cylinder 53 and expansion rod 55. A connecting ring 51 is installed at the center of each support base 31. Several elastic expansion plates 52 are evenly distributed along the inner circumference of the connecting ring 51. The inner wall of the elastic expansion plate 52 is provided with a pressing slope 521. The pressing slope 521 is driven by the expansion rod 55 to make the elastic expansion plate 52 expand outward.

[0028] Meanwhile, the cylinder 53 is installed at the bottom of the workbench 1 and its piston rod is provided with a movable frame 54 at the upper end. The movable frame 54 is provided with expansion rods 55 corresponding to the support base 31. The movable frame 54 includes a movable disk 541 and a connecting plate 542. The upper end of the piston rod of the cylinder 53 is connected to the movable disk 541. A connecting plate 542 connected to the expansion rods 55 is provided along the outer circumference of the movable disk 541. The upward movement of the movable frame 54 can simultaneously drive multiple expansion rods 55 to fix the flywheel 6.

[0029] In addition, the upper end of the expansion rod 55 is a tapered structure and it is inserted into the fixed plate 3, the support base 31, the connecting ring 51 and the elastic expansion plate 52. By moving the expansion rod 55 upward, the elastic expansion plate 52 is squeezed outward, so that the flywheel 6 is fixed on the support base 31.

[0030] Detailed implementation methods and principles:

[0031] During operation, the elastic expansion plate 52 is inserted into the center hole of the flywheel 6, and the positioning rod 32 on the support base 31 is inserted into the mounting hole on the flywheel 6.

[0032] After all the flywheels 6 are placed in all the limit slots 41 on the limit plate 4, the piston rod of the control cylinder 53 extends and drives the moving frame 54 to move upward, so that the expansion rod 55 moves in the connecting ring 51. The conical head at the upper end of the expansion rod 55 passes through the extrusion slope 521 on the inner wall of the elastic expansion plate 52, thereby driving the elastic expansion plate 52 to expand outward and extrude the flywheels 6, so that the elastic expansion plate 52 simultaneously presses and fixes multiple flywheels 6.

[0033] Next, the flywheel 6 can be welded using the appropriate welding equipment.

[0034] The embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
