Description

Technical Field

[0001] The utility model relates to the field of propeller processing, in particular to a propeller hub fitting device. Background Art

[0002] A propeller is a device that converts the engine's rotational power into propulsion by rotating blades in the air or water. It may have two or more blades connected to the hub, and the rearward side of the blade is a spiral surface or a propeller that is close to a spiral surface. The propeller is an important component of the power system.

[0003] To facilitate various tests, the propeller is stripped of all blades, leaving only the hub. This is called a test hub. Like the propeller, the test hub must be fitted to the shaft before installation. Traditionally, fitting a test hub involves supporting it with two wooden piers or steel frames, then clamping it with a pressure plate. Different test hubs require wooden piers or steel frames of varying sizes, wasting resources. Furthermore, fitting can be inefficient, making it difficult to tighten or rotate the hub. Repeated fixation is required, which is labor-intensive. Furthermore, the operation is unsafe, with the risk of injury from falling components.

[0004] Therefore, in order to solve the above problems, a propeller hub fitting device is needed to solve the above production problems. Utility Model Content

[0007] Furthermore, the height adjustment assembly includes a base mounted on the matching plate and a hydraulic jack mounted in conjunction with the base, and the top of the hydraulic jack cooperates with the wheel hub pressure plate assembly to support and position.

[0008] Furthermore, a plurality of mounting slots are provided on the whisking disc along a radial direction, the plurality of mounting slots are evenly distributed on the whisking disc, and the base is provided on the mounting slots.

[0009] Furthermore, the wheel hub limiting mechanism includes a pressure plate and a locking rod assembly installed in conjunction with the pressure plate. One end of the pressure plate is connected and installed in conjunction with the top of the hydraulic jack, and the other end of the pressure plate is pressed and installed on the wheel hub.

[0010] Furthermore, a pressure plate strip hole is opened on the pressure plate, and the locking rod assembly includes a locking rod and a locking piece used in conjunction with it. The locking rod passes through the pressure plate strip hole and the installation slot and is locked in conjunction with the locking piece.
