[0024] The present invention will be described more clearly and completely below by way of a preferred embodiment in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiment.

[0025] like Figure 1 As shown, the present invention provides a fastening structure for adjusting the level of a crane hook, comprising:

[0026] The hook centering adjustment workbench 1 is provided with a workbench plate assembly 2 for supporting the overhead crane hook assembly 5. The hook centering adjustment workbench 1 provides a stable platform for the entire assembly process, ensuring the structural stability during the assembly process.

[0027] The workbench assembly 2 is installed on the hook centering adjustment workbench 1 to provide a stable reference plane to ensure that the hook is in a horizontal state during grabbing.

[0028] The hook centering adjustment tool 3 is installed on the workbench assembly 2, and includes a reference block 8, a hook component support block 7 and a centering adjustment block 6. The reference block 8 is used to provide a horizontal reference for the overhead traveling crane hook assembly 5. The reference block 8 has high-precision flatness and horizontality requirements. For example, the surface error is set to not exceed 0.01 mm to ensure that the hook is in a horizontal state during grabbing;

[0029] The hook component support block 7 is arranged on both sides of the reference block 8, and is used to connect with the overhead crane hook assembly 5. The hook component support block 7 is provided with an elliptical mounting hole, which enables the hook part 9 to be fine-tuned in the horizontal and vertical directions to ensure the accuracy of the hook grabbing;

[0030] The centering adjustment block 6 is arranged at the center position of the reference block 8, and is used to test the grasping ability of the overhead crane hook assembly 5. The centering adjustment block 6 is provided with a mushroom head structure 10 which is the same as the wafer box. By repeatedly simulating the grasping process, it is ensured that the hook clamp can accurately fit the wafer box in actual work, and the overhead crane hook assembly 5 can achieve high-precision grasping.

[0031] The level placing tool 4 is arranged above the overhead crane hook assembly 5 and is used to detect the horizontal state of the overhead crane hook assembly 5. A level can be placed on it. The tool can also cooperate with the electronic level detection device to provide digital level detection feedback to ensure that the hook always remains horizontal during the grabbing process.

[0032] The overhead crane hook assembly 5 includes a hook part 10, and the hook part 9 is installed on the hook part support block 7. The hook part 9 includes at least one clamping claw and a support rod for grasping. The clamping claw has an adjustable clamping width, and the level of the clamping process is ensured by the combined adjustment of the hook part support block 7 and the reference block 8.

[0033] In one embodiment, the centering adjustment block 6 is made of high-strength engineering plastic or metal material, which can withstand long-term repeated operations and ensure that the accuracy is not affected by material wear during the assembly process.

[0034] The working principle of the present invention is as follows: first, adjust the level of the hook centering adjustment workbench 1, the workbench plate assembly 2 and the hook centering adjustment tooling 3, and then place the overhead crane hook assembly 5 on the hook centering adjustment tooling 3 to ensure that the hook part 9 is accurately aligned with the reference block 8 and the hook component support block 7. After ensuring that the hook assembly 5 has been correctly placed, use a level ruler to place the horizontal detection device placed on the tooling 4 for horizontal calibration, and use the mushroom head structure 10 on the centering adjustment block 6 in the hook centering adjustment tooling 3 to perform clamping simulation operations multiple times to ensure that the hook part 9 fits tightly with the mushroom head structure 10. This process can achieve subtle horizontal adjustments through the elliptical mounting holes in the hook component support block 7 to ensure that the hook assembly can be grabbed in the center. After all calibrations and conditions are completed, a final inspection is performed through the horizontal detection device and the counterweight device to confirm that the hook can be centered and kept horizontal during grabbing, thereby completing the centering adjustment of the overhead crane hook.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
