Description

[0001] Movable vessel lug milling apparatus [0002]

The present invention relates to a mobile vessel lug milling apparatus, and more particularly, to a mobile vessel lug milling apparatus capable of cutting and finishing a protruding structure such as a lug cutting mark unnecessary at the time of vessel drying.

Generally, when a ship is to be built in a shipyard, it is manufactured by assembling or connecting high-strength steel plates that make up the hull. When moving a steel plate of a certain size, a rope is mounted on a protruding structure called a lug And is moved to a predetermined position to be assembled.

A lug is a kind of rope hanger which is formed on a weight body so as to be able to be carried by a crane. Such a lug is generally provided on a metal plate or a steel structure for a bridge including a plate for manufacturing a ship.

On the other hand, the lugs protruding from the steel plate are removed after the ship assembly is completed. Generally, the removal of these lugs is done by using an arc welding machine or an oxygen cutting machine. When the lug is removed by using a welding machine, the welding surface is not clean.

Such an apparatus for performing the surface-cutting operation of the vessel uses a milling machine. However, the conventional milling apparatus is large and heavy, and is very inconvenient to move in the vessel.

Although a miniaturized milling machine has been developed to improve this, there has been an inconvenience that the milling machine has to be moved frequently due to its complicated operation and narrow working radius. Particularly, there is a disadvantage in that it is difficult to cut the left and right regions at a time in a direction perpendicular to the traveling direction at one point.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

For a better understanding of the present invention, the description with reference to the drawings is not intended to limit the scope of the present invention. In the following description, a detailed description of related arts will be omitted when it is determined that the gist of the present invention may be unnecessarily blurred.

The present invention relates to a mobile vessel capable of moving to a predetermined position in a ship and cutting a workpiece having a cutting radius larger than a conventional one in order to cut cutting residues of the lugs remaining on the surface of the vessel after assembling the vessel and cutting the lug, Lug milling apparatus.

FIG. 1 is a side view showing the overall structure of a mobile vessel lug milling apparatus according to an embodiment of the present invention. FIG. 2 is a perspective view showing the main structure of the present invention shown in FIG. 1. FIG. Fig. 4 is a front view of the present invention shown in Fig. 1. Fig.

The present invention mainly relates to an apparatus and a method for cutting a workpiece by a Y-axis transferring means 100, an X-axis transferring means 200, a lower fixing plate 600, an upper rotation plate 700, a Z- (400), and a moving means (500). In the present invention, the Y axis means a direction in which the present invention moves, that is, a fore-and-aft direction, an X axis means a horizontal direction perpendicular to the Y axis direction, and a Z axis means a vertical direction.

First, the Y-axis transfer means 100 is movable and can be fixed at a certain point on the ship, and is capable of reciprocatingly transferring the cutting means 400 in the Y-axis direction.

Specifically, the Y-axis transfer means 100 may include a Y-axis base 110, a Y-axis transfer cylinder 120, a Y-axis slider 130, and a Y-axis air hydroconverter 140.

The Y-axis base 110 may be in the form of a rectangular flat plate and disposed horizontally on the floor. A rail 110a may be formed along the longitudinal direction on both sides of the upper surface.

The stationary magnet 800 may be attached to the lower surface of the Y-axis base 110. The stationary magnet 800 may be attached to the surface of the ship with a strong magnetic force, .

At this time, the stationary magnet 800 may be a permanent magnet or may be an electromagnet under a separate control.

The Y-axis transfer cylinder 120 is installed along the longitudinal direction between the upper portion of the Y-axis base 110 and the rail 110a. In the present invention, a rodless cylinder may be used. Here, since the rodless cylinder is a cylinder widely used in the case where there is no rod or a linear reciprocating movement is required, the detailed description is omitted.

At this time, the Y-axis transfer cylinder 120 of the present invention may be hydraulically driven by the Y-axis air hydroconverter 140.

The lower fixing plate 600 is coupled to the Y-axis slider 130 slidably coupled to the Y-axis transfer cylinder 120 and reciprocally moved in the Y-axis direction.

On the other hand, a Y-axis air-hydro converter 140 is used to drive the Y-axis transfer cylinder 120. The Y-axis air-hydro-converter 140 may be installed on the X-axis transfer means 200 and may be connected to both ends of the Y-axis transfer cylinder 120 by a separate connection pipe or tube.

The Air Hydro Converter is a device that converts air pressure to hydraulic pressure and can be used to control the speed precisely. That is, since the air pressure is compressible, there is a problem that the speed can not be precisely controlled, for example, pulsation occurs at a low speed or a stick slip operation occurs.

To solve this problem, the Y-axis air-hydroconverter 140 is used to precisely control the reciprocating feed speed of the Y-axis feed cylinder 120.

Two Y-axis air hydro-converters 140 may be provided to supply hydraulic oil to both sides of the Y-axis transfer cylinder 120, and each Y-axis air hydro converter 140 may be provided in the Y- 120, respectively. Each Y-axis air-hydro converter 140 is provided with injection ports 140a and 140b through which air can be injected. The air pressure may be supplied from a separate air pump (not shown).

Accordingly, when pneumatic pressure is supplied to any one Y-axis air-hydro converter 140, the internal hydraulic pressure is injected into one side of the Y-axis transfer cylinder 120 connected thereto. Then, the piston in the Y-axis transfer cylinder 120 moves to the other side opposite to the direction in which the hydraulic pressure is injected, so that the Y-axis slider 130 interlocked with the piston is also transferred to the other side.

Conversely, when pneumatic pressure is supplied to the other Y-axis air-hydro converter 140, the internal hydraulic pressure is injected to the other side of the Y-axis transfer cylinder 120 connected thereto. Then, the piston in the Y-axis transfer cylinder 120 moves to one side opposite to the direction in which the hydraulic pressure is injected, whereby the Y-axis slider 130 interlocked with the piston is similarly transferred to the other side.

To this end, a directional valve may be provided on the Y-axis air-hydro converter 140 to selectively supply air pressure to the two Y-axis air hydroconverters.

Next, the X-axis feed means 200 will be described.

The X-axis feed means 200 is provided on the Y-axis feed means 100 to reciprocate the cutting means 400 in the X-axis direction. The X-axis feed means 200 includes an X-axis base 210, A transfer cylinder 220, an X-axis slider 230, and an X-axis air-hydroconverter 240.

The X-axis base 210 may be in the form of a rectangular flat plate and horizontally arranged on the upper side of the Y-axis transfer means 100. And a rail 210a may be formed along the longitudinal direction on both sides of the lower surface.

The X-axis transferring cylinder 220 is installed in the longitudinal direction between the lower part of the X-axis base 210 and the rail 210a. A rodless cylinder like the Y-axis transferring cylinder 120 Can be used.

Here, the X-axis transfer cylinder 220 may be driven by the X-axis air hydroconverter 240 with hydraulic pressure.

The upper rotary plate 700 is engaged with the X-axis slider 230 slidably coupled to the X-axis transfer cylinder 220 and reciprocating in the X-axis direction.

The X-axis air-hydro converter 240 is used to drive the X-axis transfer cylinder 220. The X-axis air hydroconverter 240 may be installed on the X-axis base 210 and may be connected to both ends of the X-axis transfer cylinder 220 by a separate connection tube or tube.

At this time, two X-axis air hydroconverters 240 may be provided to supply working oil to both sides of the X-axis transfer cylinder 220, and each X-axis air hydroconverter 240 is connected to the X- And is connected to both ends of the cylinder 220, respectively. The X-axis air-hydro-converter 240 is provided with injection ports 240a and 240b through which air can be injected. The air pressure may be supplied from a separate air pump (not shown).

Accordingly, when pneumatic pressure is supplied to any one of the X-axis air-hydro converters 240, the internal hydraulic pressure is injected into one side of the X-axis transfer cylinder 220 connected thereto. Then, the piston in the X-axis transfer cylinder 220 moves to the other side opposite to the direction in which the hydraulic pressure is injected, so that the X-axis slider 230 interlocked with the piston is also transferred to the other side.

Conversely, when pneumatic pressure is supplied to the other X-axis air-hydro converter 240, the internal hydraulic pressure is injected to the other side of the X-axis transfer cylinder 220 connected thereto. Then, the piston in the X-axis transfer cylinder 220 moves to one side opposite to the direction in which the hydraulic pressure is injected, so that the X-axis slider 230 interlocked with the piston is similarly transferred to the other side.

To this end, a directional valve may be provided on the X-axis air-hydroconverter 240 to selectively supply air pressure to the two X-axis air hydroconverters.

The upper rotating plate 700 may also have a circular plate shape and is coupled to the lower portion of the X-axis slider 230 of the X-axis moving means 200. Accordingly, the upper rotating plate 700 can be transferred together with the transfer of the X-axis slider 230.

The upper rotary plate 700 is reciprocally movable along the rail 210a in a state of being mounted on the rail 210a of the X-axis conveying means 200 to guide the conveying path of the upper rotary plate 700. [

At this time, a trolley 720 may be provided on the upper surface of the upper rotating plate 700 to move the upper rotating plate 700 so that the upper rotating plate 700 does not come off.

Importantly, the lower fixed plate 600 does not rotate, and the upper rotating plate 700 has a structure capable of rotating without detaching from the lower fixed plate 600.

With this structure, the X-axis transfer means 200 fixed to the upper rotary plate 700 can be rotated to the left and right, and when the Y-axis transfer means 100 is fixed at a certain position, It is possible to cut the front, rear, left, or right side of the Y-axis feed means 100 without cutting.

Preferably, a gap between the upper rotating plate 700 and the lower fixing plate 600 is filled with grease to reduce frictional friction occurring during manual rotation.

The Z-axis transfer means 300 is provided at an end of the X-axis transfer means 200 to vertically move the cutting means 400. The Z-axis transfer means 300 includes a Z-axis transfer cylinder 310, a coupler 320 And a Z-axis air-hydroconverter 330. The Z-

The Z-axis transfer cylinder 310 may be a double-rod cylinder in which the rod is provided on both sides of the cylinder, and is driven by the Z-axis air hydroconverter 330.

The Z-axis transfer cylinder 310 is installed perpendicularly to the end of the X-axis base 210 and the lower rod 312 is connected to the cutting means 400 downward.

At this time, the lower rod 312 and the cutting means 400 are connected by a coupler 320. The coupler 320 is configured to relatively move the cutting means 400 without rotating the lower rod 312, So that the rotating shaft 410 is rotatable.

For this purpose, the coupler 320 may be a thrust bearing, and more particularly, a doubly-shaped thrust bearing may be used.

The Z-axis air-hydro converter 330 for driving the Z-axis transfer cylinder 310 may be installed on the X-axis base 210 and may be connected to the Z-axis transfer cylinder 310 ). ≪ / RTI >

In addition, each Z-axis air-hydro converter 330 is provided with injection ports 330a and 330b into which air pressure can be injected. The air pressure may be supplied from a separate air pump (not shown).

Accordingly, when pneumatic pressure is supplied to any one Z-axis air-hydro converter 330, the internal hydraulic pressure is injected into the upper end of the Z-axis transfer cylinder 310 connected thereto. Then, the piston inside the Z-axis transfer cylinder 310 is lowered, whereby the rod is lowered.

Conversely, when pneumatic pressure is supplied to the other Z-axis air-hydro converter 330, the internal hydraulic pressure is injected into the lower end of the Z-axis transfer cylinder 310 connected thereto. Then, the piston inside the Z-axis transfer cylinder 310 is lifted, thereby raising the rod.

To this end, a directional valve may be provided on the Z-axis air-hydro converter 330 to selectively supply air pressure to the Z-axis air-hydro converter.

Meanwhile, the upper rod 311 of the Z-axis transfer cylinder 310 may be a screw 311a having a screw thread formed on the outer peripheral surface thereof. An adjustment knob 340 may be screwed to the upper rod 311.

Therefore, when the adjustment knob 340 is manually rotated, the screwed upper rod 311 can be raised and lowered finely, thereby finely adjusting the height of the cutting means 400 connected to the lower rod 312 Can be adjusted manually.

Next, the cutting means 400 will be described.

The cutting means 400 is a tool that is in close contact with the surface of the vessel for performing a cutting operation and is axially coupled to the lower rod 312 of the Z-axis transfer cylinder 310.

More specifically, the cutting means 400 may include a rotating shaft 410, a milling cutter 420, a driven pulley 430, a driving motor 440, a driving pulley 450, and a belt 460.

The rotation shaft 410 is rotatably coupled to the lower rod 312 in an axial direction by the coupler 320. A spline groove 410a is formed in a part of the outer circumferential surface of the rotary shaft 410 in the axial direction.

A driven pulley 430 is horizontally coupled to the rotating shaft 410 to rotate the rotating shaft 410. The driven pulley 430 is splined to the splined groove 410a. The driven pulley 430 is rotatable by a separate bearing but installed so as not to move up and down.

Accordingly, the driven pulley 430 can rotate together with the rotation shaft 410, and the rotation shaft 410 can move up and down in the axial direction.

The milling cutter 420, which performs a cutting operation, is coupled to the lower end of the rotation shaft 410 and rotates. The milling cutter 420 may be replaceable.

A driving motor 440 is installed on the X-axis base 210 and a driving pulley 450 is coupled to the motor shaft of the driving motor 440.

The driving pulley 450 and the driven pulley 430 are wound by a belt 460 and interlocked with each other in order to transmit the power of the driving motor 440 to the rotating shaft 410.

The driving motor 440 is installed on the opposite side of the Z-axis conveying means 300, and the X, Y, and Z-axis air hydroconverters may be arranged in a row between the driving motor 440 and the Z- A separate duct 470 is further provided on the X-axis base 210 to connect the driving pulley 450 and the driven pulley 430 with the belt 460.

When the moving motor 520 is operated, the wheel 510 is driven so that the present invention moves forward or backward. At this time, it is possible to change the direction using the handle 550.

The X axis base 210 is lowered and the stationary magnet 800 is attached to the surface of the ship when the elevator cylinder 530 is operated again to raise the wheel 510. As a result, Is fixed without being shaken.

For example, if the cutting operation is performed from the right side, the Y-axis feed means 100 is driven to move the X-axis feed means 200 to the uppermost position, and the X-axis feed means 200 is driven, The means 400 is positioned adjacent to the upper right end of the X-axis base 210 and then the Z-axis transport means 300 is driven to move the milling cutter 420 of the cutting means 400, So as to be brought into close contact with the surface of the ship.

In this case, the adjustment knob 340 can be finely adjusted so as to be closely contacted in consideration of the depth to be cut.

Then, the driving motor 440 is driven to rotate the milling cutter 420.

When the Y-axis transfer cylinder 120 is driven by operating any one of the Y-axis air hydro-converters 140 in this state, the Y-axis slider 130 moves slowly, and the lower fixed plate 600, 700, X-axis feed means 200, and cutting means 400 all move down together. That is, ① cut the surface of the ship while moving from the point.
