A precise grinding and painting device for ship propeller production

Abstract

The invention relates to the technical field of ship parts processing, and discloses a precision grinding and painting device for ship propeller production, which includes a fixed bracket and a hydraulic press, and the clamping and rotating mechanism includes an outer clamping ring, a central clamping rod, a rotating drive rod, Rotate the drive motor and speed conversion disc. By setting the telescopic connecting rod, the grinding motor, the grinding head and the spraying head are synchronously lowered under the drive of the hydraulic press, so that the grinding head falls to the position where grinding needs to be performed, and then the grinding drive rod is driven by the grinding motor to rotate together with the grinding head, while grinding The small change of the grinding position is controlled by the cable reel and the telescopic link, and the range of the parts to be polished is ground, so that the grinding head can extend into the gap of the propeller that needs to be polished, so that the grinding head can grind all parts of the propeller. operation to improve the applicability of the device.

Description

technical field [0001] The invention relates to the technical field of ship parts processing, in particular to a precise grinding and painting device for ship propeller production. Background technique [0002] The propeller is the most widely used ship propeller among all kinds of ship propellers. It is an important part of the ship. It is used to convert the torque output by the ship engine into thrust to propel the ship. According to the demand, the types of ship propellers are also varied. And with the continuous development of the shipbuilding industry, modern ships are developing towards large-scale and high-speed, and the performance requirements of ships for propellers are constantly improving. The difference in the smoothness of the propeller surface will have a great impact on the propeller's dynamic effect, so the quality of the propeller grinding directly affects the transmission efficiency and the service life of the propeller. [0003] The existing propeller ...
