Ship propeller machining special machine tool and machining method thereof

Abstract

The invention relates to a ship propeller machining special machine tool. The machine tool comprises an operation base, a chip removal device, a propeller rough machining device, a propeller finish machining device, a propeller installing and positioning device and a machine tool driving device, wherein the middle of the operation base is provided with a pit used for placing a to-be-machined propeller, the propeller installing and positioning device is arranged in the pit, the machine tool driving device is arranged around the propeller installing and positioning device, the two ends of the machine tool driving device are provided with the propeller rough machining device for propeller machining and the propeller finish machining device for propeller machining correspondingly, and the rough machining device and the finish machining device can perform rough machining and finish machining on a blade root and a propeller hub of the propeller at the same time. According to the machine tool, the two machining devices are adopted to be symmetrically arranged, a vertical machining method is adopted for the blade root and the propeller hub of the propeller, the two machining devices can perform rough machining and finish machining at the same time, the machining efficiency is greatly improved, and rough and finish machining integration is achieved.

Description

technical field [0001] The invention relates to a numerical control special machine tool for machining propeller blade roots and propeller hubs for ships, belongs to the technical field of mechanical processing equipment, and is particularly suitable for processing large propeller propeller blade roots and propeller hubs for ships. Background technique [0002] Ships are the main means of water transportation and an important propeller of economic globalization. With the rapid development of the economy and the exhaustion of land resources, ships are bound to become a sharp weapon for the development of sea resources. Marine propeller is a key power component of marine equipment, and its processing efficiency is the guarantee for enterprises to respond quickly to market demand. For a long time, the machining of large marine propellers has been done by milling the propeller blades with machine tools, and using a grinder to grind the blade roots and hub parts manually. The m...

AI Technical Summary

Problems solved by technology

The main disadvantages of this processing method are as follows: 1. Grinding is completely dependent on the experience and technical level of the grinder, and the instability is high, the grinding track is messy, the allowance is uneven, and the grinding force is difficult to control stably.

2. Low processing efficiency: At present, 4 grinders are required to process a 10-meter propeller, and it takes 4 days to grind

3. The intensity of manual grinding is high, and the long-term harsh operating environment will affect the health of workers
