Rudder bearing cutting tool

Abstract

The invention discloses a rudder bearing cutting tool. The rudder bearing cutting tool comprises a cutting head, a radial adjusting mechanism and an axial adjusting mechanism which are connected in sequence, the cutting head comprises a milling cutter, a milling cutter chuck and an angular wind mill which are connected in sequence; the radial adjusting part comprises a plurality of fixed supporting rods and a radial adjusting screw rod, a guide rail is arranged between the fixed supporting rods, the angular wind mill slides along the guide rail, a threaded section is arranged at one end of theguide rail, one end of the radial adjusting screw rod is connected with the angle air mill through the threaded section; the axial adjusting mechanism connected with the fixed supporting rods is arranged in the vertical direction of the plane formed by the cutting head and the radial adjusting mechanism, an axial multi-groove sliding rail is arranged between the fixed supporting rods, the angularwind mill is connected with one end of the hollow axial adjusting screw rod to move along the multi-groove sliding rail, and the other end of the hollow axial adjusting screw rod is provided with a control switch and an air interface. The rudder bearing cutting tool has the advantages of being convenient to install, safe to use, low in manufacturing cost, complete in cutting work, free of damageto a rudder bearing sleeve and the like.

Description

technical field [0001] The invention relates to the technical field of cutting tools, in particular to a rudder bearing cutting tool. Background technique [0002] In the process of ship repair, it is often necessary to disassemble the worn out old rudder bushes. The rudder bushes are made of polymer synthetic materials. The rudder bushes are generally installed after interference freezing, and the worn rudder bushes cannot be disassembled at room temperature. [0003] If the old rudder bushing is removed by freezing and shrinking, it is necessary to move the freezing facility to the position of the rudder bearing at a height of 5 to 10 meters, and also need to process auxiliary facilities such as the pressing plate screw rod. The operation process is complicated and the cost is huge, so this method is generally not used method disassembly. Generally, an angle wind mill and a saw-like milling cutter are used to remove the old rudder bushing by freehand cutting or oxyacetyle...

AI Technical Summary

Problems solved by technology

[0004] 1. The removal of the rudder bearing by hand cutting cannot control the cutting depth, often leaving many irregular cutting marks on the rudder bearing body, which affects the appearance of the external rudder bearing

[0005] 2. Due to the particularity of the disc saw blade milling cutter, the circular arc dead angle is left in the rotary cutting, and it is impossible to undercut the rudder bushing with a step limit

[0006] 3. The thickness of the chip milling cutter is only 3mm, and the freehand cutting groove is not standardized. Only one irregular groove is cut, and the outer diameter of the rudder bush cannot be taken out after reaching the constriction. It is necessary to cut 2 to 3 pieces to waste cutting time. Cutting time, it takes at least 3 to 4 hours to routinely cut a rudder bushing with a diameter of Φ500

[0007] 4. When using the milling cutter to deepen the cut with bare hands, it is impossible to control the original state of the chip milling cutter in the cut groove. Due to uneven force, the chip cutter (Φ200) cracks in the cut groove and cracks The fragments fly out with the high-speed rotating (above 3000) milling cutter fragments, which will cause injury and safety accidents

[0009] 1. It is difficult to control the flame burning. Since the surface of the inner hole of the full-suspension rudder stock body is covered with butter and grease, it is easy to cause fire and other safety accidents.

[0010] 2. Rudder bearings made of polymer materials melted by flames will cause incomplete combustion, cause environmental pollution, and affect the health of workers

[0011] 3. After the flame is melted, it is easy to cause local deformation of the rudder bearing body, which will bring quality accidents to the measurement of the newly equipped rudder bearing
