Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of propeller processing, in particular to a propeller grinding mechanism. Background Art
[0002] Propeller grinding mechanism is mainly used for surface treatment and finishing of propellers to improve the propulsion efficiency and stability of ships, aircraft and other equipment. Propeller grinding is a high-precision job that requires the use of specific mechanical equipment and tools to ensure that the accuracy and finish of the propeller surface meet the design requirements;
[0003] Before grinding the propeller, it is necessary to fix the propeller to prevent it from moving or shaking during the process. This is because the propeller is usually made of large metal materials and is heavy. If it is not fixed properly, it will cause safety hazards to the operator and may cause damage to mechanical equipment and tools.
[0004] The fixing components in some existing propeller grinding devices are usually composed of splints and bolts. When used by workers, the two splints need to be placed on the top and bottom of the propeller wing respectively. After placement, the bolts need to be installed into the threaded grooves of the splints using tools so that the two splints can limit the position. However, during the grinding process, in order to maintain its stability, the position of the splint clamping may need to be changed frequently. In this case, the worker needs to replace the clamping part after removing the bolt with the tool. Frequent removal and replacement of the bolts requires additional time and labor. Each adjustment of the clamping position requires loosening and tightening the bolts, which increases the complexity and time-consuming nature of the operation. Utility Model Content

[0008] As a preferred embodiment, four fixing frames are equidistantly arranged in a square shape on the outer side of the top of the lifting device, and the plurality of fixing frames are threadedly fixed to the thread grooves provided in the lifting device through fixing members.
