Profiling tool for machining parts and components of ships and method thereof

Abstract

The invention relates to a profiling tool for machining parts and components of ships and method thereof. The profiling tool comprises a big raft, a tail clamping press tool, a square window clamping press tool, a small-end bottom support tool, a rear profiling plate tool, a waist supporting and clamping press tool, a front profiling plate tool and a big-end back surface supporting and clamping press tool; the big raft is fixedly connected with a local supporting tool; the tail clamping press tool is used for carrying out clamping press through a small-end surface circular hole of a machined part support; the square window clamping press tool is used for carrying out clamping press through the end surface of a small-end square window; the small-end bottom supporting tool is supported on the big raft through a circular navel in the center of the bottom of a small end; both the front profiling plate tool and the rear profiling plate tool are supported on the waist bottom surface of the machined part support; the waist supporting and clamping press tool is used for carrying out supporting and clamping press through a waist navel; the big-end back surface support clamping press tool is used for carrying out supporting and clamping press through a navel additionally arranged on the back surface of a big end. The profiling tool and the profiling tool disclosed by the invention has the beneficial effects that the production cost is reduced on the premise of ensuring the quality and the safety, the machining efficiency is improved, and precision machining of parts and components of ships is realized.

Description

technical field [0001] The invention relates to a processing and clamping method applied to key component brackets such as ship propulsion and rudder systems, in particular to a profiling tool and method for processing ship parts, which belong to the field of mechanical processing industry. Background technique [0002] It can be seen from the changes in the share of China's shipbuilding industry in the world's shipbuilding market in recent years that the proportion of China's shipbuilding industry in the global market is rising significantly, and China has become one of the world's important shipbuilding centers. From January to April 2014, in terms of statistics on the three major indicators of the world's shipbuilding industry (shipbuilding completions, orders in hand, and new orders), China has become the world's largest shipyard far ahead of Japan and South Korea. However, although my country's shipbuilding capacity has ranked among the top in the world, the problems of...

Problems solved by technology

However, although my country's shipbuilding capacity has been ranked among the top in the world, the problems of poor overall technical level and low development level are more prominent, and some high-tech and high value-added ships have not yet gotten rid of the situation of relying on foreign designs

The development of professional equipment for ships in my country is relatively backward, and the design and manufacturing capabilities of professional equipment are insufficient. Many equipment must be imported from abroad. Our design capabilities are still very backward, and the lagging development of supporting industries will be the main bottleneck restricting the development of the industry.

As a key component bracket for ship propulsion and rudder steering, due to its special shape design, it is very difficult to lock in the finishing process. At present, it is still impossible to use conventional methods to realize the "six-point positioning principle"

[0003] In addition, the outline of the bracket is a circular arc surface except for the processing surface. According to the conventional method, the clamping cannot be realized, and the finishing requirements of the φ2460mm annular groove depth dimension of 4.75±0.05mm in the drawing cannot be guaranteed; solve the clamping and leveling The problem of alignment can be solved by designing the casting process navel
