Problems solved by technology

The rudder arm is a large structural part with irregular geometric shape, large outline and complex structure. Its hole machining precision requires high precision and needs to be welded with the hull and processed on site, so the above method cannot be directly used
At present, domestic shipyards generally use the power head to process the rudder arm hole. The technology is backward, the processing cost is high, the production efficiency is low, the labor intensity is high, and the accuracy is not easy to guarantee. Therefore, the processing of large rudder arm holes is difficult and the processing cost is high. Has become the focus and difficulty of ship machining

Embodiment Construction

[0015] Such as figure 1 Among them, a rudder arm boring tool, the two ends of the boring bar 3 are provided with the centering device 2, the knife rake 4 is provided between the centering device 2, and one end of the boring bar 3 is connected to the flange 5 and the universal joint 6 connect.

[0016] The boring bar 3 is a hollow structure, and centering holes 1 are provided on the end faces of both ends of the boring bar 3 .

[0017] The knife rake 4 is provided with a knife advancing and retreating device.

[0018] Such as figure 2 , image 3 Among them, the knife rake 4 is provided with a knife track 41, and one end of the knife track 41 is provided with an adjusting bolt 43 for adjusting the advance and retreat of the knife. By adjusting the adjusting bolt 43 fixed on the knife rake 4, the knife seat in the knife rail 41 is pushed to move back and forth along the knife track 41, thereby realizing the advance and retreat of the knife.

[0019] The knife rake 4 is also...

Abstract

The invention relates to a rudder horn boring hole tool. Two ends of a boring rod is provided with center adjusting devices, a blade harrow is arranged between the center adjusting devices, and one end of the boring rod is connected with a flange and is connected with a cardan joint. The invention provides the rudder horn boring hole tool, by adopting the boring rod with a made-to-order structure, high shape and position precision is guaranteed, through an experimental test, the technical problem of machining the rudder horn hole is effectively solved, manufacturing quality requirements of a rudder horn are satisfied, and the rudder horn boring hole tool is provided with a good application value in a shipbuilding industry. The rudder horn boring hole further has the advantages of being simple in structure, good in body rigidity, convenient to install and use, high in manufacturing efficiency, and precision is easy to guarantee.

Description

technical field [0001] The invention relates to a tool, in particular to a tool for boring a rudder arm with a large rudder arm hole. Background technique [0002] A 6000t asphalt ship, the rudder blade adopts semi-suspended type, the rudder stock and rudder pin are connected to the rudder blade through the upper and lower rudder bearings of the rudder arm, the outer dimension of the rudder arm is 3.9m×0.7m×4.9m, and the weight is 12t, the size of the upper rudder bearing hole is φ351mm, the length is 350mm, the size of the lower rudder bearing hole is φ362mm, the length is 360mm, the distance between the two holes is 1710mm, and the surface roughness of the two holes is required to be 1.6μm after processing , the coaxiality is 0.1mm, and it needs to be assembled and welded with the hull and processed on site. [0003] Deep hole processing is a kind of problem often encountered in mechanical processing. The commonly used processing methods are: small holes are processed on ...
