Device for producing ship propeller

Abstract

The invention discloses a device for producing a ship propeller. The device for producing the ship propeller comprises a constant-pressure floating grinding head, a bottom rotating device, a rack, a left-right moving device and an air source, wherein the bottom rotating device is arranged at the bottom of the rack, and the constant-pressure floating grinding head is arranged on the rack and can float up and down along with the curved surface of the propeller for grinding; and the left-right moving device is connected with the constant-pressure floating grinding head and the bottom rotating device in a matched mode, so that the bottom rotating device drives the constant-pressure floating grinding head to slowly move backwards while rotating. According to the device for producing the ship propeller, the blade surface of the propeller is automatically ground by a machine, the pressure of the grinding head is always kept consistent, and the grinding depth and the surface smoothness are kept uniform, so that the labor cost is greatly saved, and the grinding quality is controllable.

Description

technical field [0001] The invention relates to the field of special manufacturing equipment for ship propellers, in particular to a device for producing ship propellers. Background technique [0002] The ship propeller is the source of power for the ship to sail in the water. Its rotation pushes the water to rotate backwards, and relatively makes the ship sail forward. During the rotation of the propeller, it is always in contact with the water. Therefore, if the surface of the propeller is not smooth enough, it will The resistance is quite large, which will consume more energy. However, the existing propeller polishing equipment for ships is basically polished by people, which is time-consuming and has large individual differences. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the invention provides a device for producing ship propellers. [0004] In order to solve the above technical problems, the present invention is solved by the fol...
