Description

Technical Field

[0001] This utility model relates to the field of clamping technology for steering wheel die casting, and in particular to a clamping mechanism for steering wheel die casting. Background Technology

[0002] After the steering wheel frame is die-cast, it needs to be removed from the mold for random inspection.

[0003] For example, the automotive steering wheel frame die-casting clamping device disclosed in announcement number CN221455715U includes a support column and a clamping plate disposed on the left side of the support column. A support block is provided at the upper end of the support column, and a lifting mechanism is provided between the support block and the support column. A groove is provided at the upper end of the support block, and a support wheel is provided within the groove. A first drive mechanism is provided within the support wheel, and a support mechanism is provided between the support wheel and the clamping plate. Four annularly distributed sliding grooves are provided on the front side of the clamping plate near its edge. Two clamping blocks are slidably connected to the inner sidewall of the sliding grooves, with portions of the clamping blocks penetrating the sliding grooves. A bidirectional screw is provided within the sliding grooves. A circular storage slot is provided inside the clamping plate near its center. However, the above technology still has problems in use due to structural limitations.

[0004] The aforementioned technology uses two clamping blocks to hold the steering wheel. However, these two clamping blocks are rectangular in structure. Since the steering wheel shrinks when cooled after being die-cast at high temperature, the clamping blocks may not be able to hold the steering wheel securely during movement, causing the steering wheel to fall off the clamping plate and injure the equipment or the operator. In addition, the clamping plate of this device cannot be rotated, and it needs to be manually removed when it is moved above the testing platform, which is cumbersome. Utility Model Content

[0005] The purpose of this invention is to solve the problems of unstable clamping and cumbersome handling in existing steering wheel die-casting clamping devices, and to propose a clamping mechanism for steering wheel die-casting.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A clamping mechanism for die-casting a steering wheel includes a clamping frame, a clamping disc on the side of the clamping frame, the clamping disc and the upper end of the clamping frame rotating through a rotating mechanism, an adjusting mechanism at one end of a connecting rod in the rotating mechanism, a connecting bracket fixedly connected to the side end of the clamping disc, and the connecting bracket and the clamping disc rotating as a whole through the adjusting mechanism, and a clamping mechanism for clamping the steering wheel in the clamping disc.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-5 A clamping mechanism for die-casting a steering wheel includes a clamping frame 1, a clamping plate 3 on the side of the clamping frame 1, the clamping plate 3 and the upper end of the clamping frame 1 are rotated by a rotating mechanism, one end of the connecting rod 2 in the rotating mechanism is provided with an adjustment mechanism, a connecting bracket 8 is fixedly connected to the side end of the clamping plate 3, and the connecting bracket 8 and the clamping plate 3 as a whole are rotated by the adjustment mechanism, and the clamping plate 3 is also provided with a clamping mechanism for clamping the steering wheel.

[0023] The rotating mechanism includes a connecting column 4, a first drive motor 5, a first motor shaft 6, and a drive shaft 7. The connecting column 4 is fixedly connected to the connecting rod 2. The first drive motor 5 is fixedly installed on the upper end of the clamping frame 1. The first motor shaft 6 is fixedly connected to the output end of the first drive motor 5. The drive shaft 7 is fixedly connected to the first motor shaft 6.

[0024] The adjustment mechanism includes a second drive motor 9, a second motor shaft 10, a connecting shaft 11, a limiting block 12, and a limiting groove 13. The second drive motor 9 is fixedly connected to the connecting rod 2, the second motor shaft 10 is fixedly connected to the output end of the second drive motor 9, the connecting shaft 11 is fixedly connected to the second motor shaft 10, the limiting block 12 is fixedly connected to the connecting rod 2, and the limiting groove 13 is opened in the connecting bracket 8.

[0025] The limiting groove 13 is a quarter-circular arc groove structure. This design has two functions: first, to limit the limiting block 12 and ensure the stability of the device; second, to ensure that the clamping plate 3 rotates exactly 90 degrees so that the steering wheel can land on the detection table in a horizontal state. In addition, the limiting block 12 is equipped with a pressure sensor. When the two ends of the limiting block 12 and the limiting groove 13 are in contact, the pressure sensor can transmit a signal to the second drive motor 9, so that the second drive motor 9 can stop rotating.

[0026] The clamping mechanism includes a third drive motor 14, a third motor shaft 15, a rotating shaft 16, and a first gear 17. The third drive motor 14 is fixedly installed in the clamping disk 3. The third motor shaft 15 is fixedly connected to the output end of the third drive motor 14. The rotating shaft 16 is fixedly connected to the third motor shaft 15 and is rotatably connected to the clamping disk 3. The first gear 17 is fixedly connected to the rotating shaft 16.

[0027] The clamping mechanism also includes a second gear 18, a limiting bracket 19, a threaded rotating rod 21, a clamping bracket 20, and a bracket groove 22. The second gear 18 is meshed with the first gear 17. The limiting bracket 19 is integrally formed in the clamping disk 3. The threaded rotating rod 21 is fixedly connected to the second gear 18 and rotatably connected to the limiting bracket 19. The clamping bracket 20 is threadedly connected to the threaded rotating rod 21. The bracket groove 22 is opened in the clamping disk 3 and slidably connected to the clamping bracket 20.

[0028] The second gear 18, the limiting bracket 19, the threaded rotating rod 21, the clamping bracket 20, and the bracket slide groove 22 are arranged in four sets, symmetrically in the clamping plate 3. The limiting bracket 19 can limit the threaded rotating rod 21, allowing it to rotate only in one direction. The clamping bracket 20 has a hook-shaped structure; when clamping the steering wheel, it... Figure 5 As shown, the structure at the bottom of the clamping bracket 20 can limit the steering wheel, preventing it from shifting vertically and from falling off due to cold shrinkage.

[0029] After the steering wheel die-casting is completed, the clamping disc 3 is aligned with the steering wheel, the die-casting equipment pushes the steering wheel out, and the third drive motor 14 is started. The third drive motor 14 drives the rotating shaft 16 to rotate through the third motor shaft 15. The rotating shaft 16 drives the first gear 17 to rotate, the first gear 17 drives the second gear 18 to rotate, the second gear 18 drives the threaded rotating rod 21 to rotate, and the threaded rotating rod 21 drives the clamping bracket 20 to move in the bracket slide groove 22, as shown in the attached figure. Figure 1 As shown, the four clamping brackets 20 move outward and clamp the steering wheel. Because the clamping brackets 20 have a hook-like structure, the steering wheel will not fall off the clamping plate 3. After clamping, the first drive motor 5 is activated. The first drive motor 5 drives the drive shaft 7 to rotate via the first motor shaft 6. The drive shaft 7 drives the connecting column 4 and the connecting rod 2 to rotate. When the connecting rod 2 rotates 180 degrees, the clamping plate 3 rotates to the top of the testing platform. At this time, the second drive motor 9 is activated. The second drive motor 9 drives the connecting shaft 11 to rotate via the second motor shaft 10. The connecting shaft 11 drives the connecting bracket 8 to rotate. Due to the action of the limiting block 12, as shown in the attached diagram... Figure 4 As shown, the connecting bracket 8 will stop rotating after rotating 90 degrees. At this time, the steering wheel will face downwards. Then, the clamping bracket 20 will be released, and the steering wheel will fall onto the testing platform.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
