Description

Technical Field

[0001] The utility model relates to the technical field of gear ring processing, in particular to a wind power gear box gear ring sandblasting tool. Background Art

[0002] Sandblasting is a commonly used surface treatment process, which is widely used in the surface pretreatment of various materials such as metal, stone, glass, plastic, etc. Sandblasting is to remove the oxide scale, rust, old paint layer, dirt, etc. on the surface of the workpiece by spraying abrasives (such as corundum, iron sand, glass beads, etc.) at high speed. At the same time, it can change the roughness of the surface of the object, increase the surface adhesion, and provide good base conditions for subsequent spraying, bonding, anti-corrosion treatment and other processes. In the processing of the gear ring of the wind power gearbox, the outer circle of the gear ring will be sandblasted. During the sandblasting process, it is necessary to ensure efficient removal of impurities on the outer circle surface while avoiding abrasives from accidentally damaging the end face and internal tooth structure of the gear ring. The existing technology is to place the workpiece on the workbench, and then cover the upper end face of the workpiece with a cover plate to prevent the abrasive from damaging the end face and internal structure of the workpiece. However, according to different processing requirements of the gear ring, some parts of the outer circle of the gear ring may need to be sandblasted, while other parts do not need to be treated. The cover plate of the prior art cannot accurately adapt to the complex and changing process requirements, resulting in complex processes, low processing efficiency, and low gear ring precision. Utility Model Content

[0003] The utility model provides a wind power gear box gear ring sandblasting tooling, which can solve the problem that it cannot accurately adapt to complex and changeable process requirements, resulting in complex process, low processing efficiency and low gear ring accuracy.

[0006] Beneficial effects: The annular block of the backing plate can accurately match the shape of the gear ring, ensuring that the gear ring maintains a stable and precise position during the sandblasting process, while preventing abrasives from directly impacting the end face and outer circle of the stopper of the gear ring, protecting it from damage. The annular block of the cover plate complements the annular block on the backing plate, further reinforcing the positioning of the gear ring during the sandblasting operation, while preventing abrasives from directly impacting the end face, outer circle of the stopper and internal tooth structure of the gear ring, ensuring the sealing and stability of the entire sandblasting process. The lifting threaded holes of the backing plate facilitate the safe and quick handling and fixing of the tooling using lifting equipment, improving the safety and efficiency of the operation. The reinforcing ribs of the cover plate not only strengthen the structural strength of the cover plate to prevent deformation during lifting or operation, but also provide additional lifting points through the lifting rings on it, which is convenient for flipping or moving during operation, and is highly practical. The combination of the backing plate and the cover plate can accurately adapt to complex and changing process requirements, simplify the process, have high processing efficiency, and high gear ring precision.

[0007] Furthermore, an annular stopper is provided at the edge of the backing plate, and an annular stopper ring is provided at the edge of the cover plate.

[0008] Beneficial effects: The annular block and the annular retaining ring can fit tightly with the gear ring, ensuring that the gear ring is maintained in a precise position during the sandblasting process, avoiding misalignment caused by vibration or injection force, reducing processing errors, and facilitating cleaning and maintenance after operation.

[0009] Furthermore, two lifting threaded holes are symmetrically provided in the middle of the base plate.

[0010] Beneficial effect: It can ensure the balance of the center of gravity when hoisting the gear ring and tooling, reduce the deflection or shaking during the hoisting process, and improve the safety and stability of the operation.

[0011] Furthermore, the pad and cover plate are both cylindrical structures, the reinforcing ribs on the cover plate are cross-shaped structures, the central intersection of the cross-shaped structure is located at the center of the cover plate, and the lifting ring is located at the central intersection of the cross-shaped structure.

[0012] Beneficial effect: Enhance the overall stability and deformation resistance of the tooling, especially when subjected to vibration and impact during sandblasting operations.

[0013] Furthermore, the lifting ring is detachably connected to the reinforcing rib of the cover plate.

[0014] Beneficial effects: The lifting ring can be quickly installed or removed according to actual needs, which facilitates the storage and transportation of the tooling and adapts to different types of lifting equipment, thereby improving the versatility and applicability of the tooling.

[0015] Furthermore, the annular stopper is detachably connected to the backing plate.

[0016] Furthermore, the annular retaining ring is detachably connected to the cover plate.

[0017] Beneficial effects: The gear rings of different sizes and shapes can be quickly replaced or adjusted, so that the same tooling can be compatible with gear rings of various specifications, thereby improving the versatility and flexibility of the tooling. BRIEF DESCRIPTION OF THE DRAWINGS
