Mounting and positioning device convenient for assembling propeller

Abstract

The invention discloses a mounting and positioning device convenient for assembling a propeller. The device comprises an operation table, the top of the operation table is provided with a positioning groove, the two sides of the bottom of the operation table are fixedly connected with supporting legs, and U-shaped blocks are slidably connected between the two sides of the two supporting legs. According to the device, two clamping plates are indirectly driven to move towards the side, away from each other, by stepping on a pedal, a hub on the propeller is placed in the positioning groove, two sliding blocks are extruded through the elastic force effect of an extrusion spring, and then the two clamping plates are indirectly driven to further fix the hub on the propeller through the movement of the sliding blocks; through the arrangement of a clamp, a blade can be clamped, an electric telescopic rod stretches out and draws back to drive the blade to move, and the output end of a servo motor rotates to indirectly drive the blade to rotate, so that the angle of the blade is adjusted, a worker can conveniently fix the blade and the hub, and therefore, the convenience of welding the propeller by the worker is improved.

Description

Technical field[0001]The present invention relates to a propeller, specifically a mounting device for facilitating propeller assembly.Background technique[0002]The propeller refers to a device that rotates in air or water, and converts the engine rotation power into a propulsive force. There may be two or more leaves connected to the hub, and the backward side of the leaves is a spiral surface or approximately a spiral surface. A propeller. The propeller is divided into many, and the application is also very wide, such as aircraft, ship propeller, etc.[0003]Most of the existing propeller is fixed by the leaf and the hub, but when the leaf is welded to the hub, since the leaf is quickly fixed, the working efficiency is lowered, and during welding The angle of the blade and the hub is prone to offset, and it is not possible to achieve the precision positioning of the propeller, which is easily derived from the welded propeller to be poorly stabilized during use.Inventive content[0004]...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing propellers are fixed by welding between the blade and the hub. However, when the blade and the hub are welded, the work efficiency is reduced because the blade and the hub cannot be effectively fixed quickly, and during the welding process The angle between the blade and the hub tends to deviate, which makes it impossible to achieve precise positioning of the propeller, which easily leads to poor stability of the welded propeller during use
