By installing the two drilling machines symmetrically so as to have a 180 degree intervals about the rotating plate for the large ship engine, it is possible to simultaneously process two cooling holes in two parts of the cylinder liner fixed to the rotating plate. Provided cylinder liner cooling hole processing device.

According to another embodiment of the present invention, the present invention provides a rotary plate installed to divide and rotate at a predetermined speed, a rotary plate driving device connected to the rotary plate to drive the divided rotary movement, and a cylinder liner installed on the rotary plate. Cylinder liner fixing portion consisting of a fixing device for vertically fixing the

A pillar, a pillar base coupled to the pillar to support the pillar, a pillar driving device for moving the pillar base in a horizontal direction, a spindle head mounted on the pillar to move up and down along the pillar, and the spindle head It includes three drilling machines, which are installed in the machine, are equipped with a machining tool, are connected to a spindle drive, and comprise a spindle for rotating the machining tool.

By installing the three drilling machines radially so as to have a 120 degree intervals about the rotating plate for the large marine engine, it is possible to process three cooling holes in three parts of the cylinder liner fixed to the rotating plate at the same time Provided cylinder liner cooling hole processing device.

The cylinder liner cooling hole processing apparatus for a large ship engine according to the present invention can improve productivity by reducing the processing time of the cylinder liner cooling hole by simultaneously processing two or three cooling holes by installing a cylinder liner and a drilling machine vertically. It has an effect.

Figure 3 is a cross-sectional view of the processing of the cylinder liner cooling hole for a large ship engine according to an embodiment of the present invention.
Figure 4 is a cross-sectional view of the processing of the cylinder liner cooling hole for a large ship engine according to another embodiment of the present invention.

While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It should be understood, however, that the invention is not intended to be limited to the particular embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention. Like reference numerals are used for like elements in describing each drawing.

Hereinafter, with reference to the accompanying drawings, it will be described an embodiment of the cylinder liner cooling hole processing apparatus for a large marine engine according to the present invention.

2 and 3, the cylinder liner cooling hole processing apparatus for a large ship engine according to the present embodiment includes a cylinder liner fixing part 100 and a drilling machine 200.

The cylinder liner fixing part 100 is to allow the cylinder liner 5 to be fixed and dividedly rotated, and includes a rotating plate 110, a fixing device 120, and a rotating plate driving device 130.

The rotating plate 110 is installed to be divided and rotated at a predetermined speed. As the rotating plate 110 is divided and rotated, the cylinder liner 5 coupled thereto is also divided and rotated.

The fixing device 120 is installed between the rotating plate 110 and the cylinder liner 5 to fix the cylinder liner 5 to the rotating plate 110.

The rotating plate driver 130 drives the rotating plate 110 to perform a divided rotational movement.

The drilling machine 200 includes a pillar 210, a pillar base 212, a pillar driving device 214, a spindle head 220, and a spindle 230.

The pillar base 212 is installed in close proximity to the rotating plate 110 to support the pillar 210 and to guide in the horizontal direction.

The pillar 210 is installed on an upper portion of the pillar base 212 and is coupled to the pillar base 212 and moved together in a horizontal direction according to the movement of the pillar base 212.

The pillar driving device 214 provides a driving force to move the pillar base 212 in the horizontal direction. Here, the horizontal direction refers to the front, rear, left and right directions, and when expressed in a rectangular coordinate system, the horizontal direction refers to the X-axis and Z-axis directions.

The spindle head 220 is installed on the pillar 210 to move up and down along the pillar 210. That is, it descends in the vertical direction (ie, Y-axis direction) along the pillar 210.

The spindle head 220 is equipped with a machining tool 240, the spindle 230 is connected to the spindle drive to rotate the machining tool 240 is installed.

In addition, the spindle 230 is connected to a spindle moving device (not shown) and can be moved back and forth by the spindle moving device.

As a result, after the machining tool 240 is mounted to the spindle 230, when the spindle 230 is rotated, the spindle 230 and the machining tool 240 are directed toward the cylinder liner 5. Cooling hole 15 is formed in the cylinder liner 5 while advancing.

According to one embodiment of the present invention shown in Figures 2 and 3, the two drilling machine 200 is installed symmetrically with a distance of 180 degrees around the rotating plate 110 to the rotating plate 110 Since the two cooling holes 15 can be simultaneously processed in two portions of the fixed cylinder liner 5, the machining operation of the cooling holes 15 is faster and the productivity of the product is improved.

According to another embodiment of the present invention shown in FIG. 4, three drilling machines 200 are radially installed to have an interval of 120 ° about the rotary plate 110 to be fixed to the rotary plate 110. Since three cooling holes 15 may be simultaneously processed in three portions of the liner 5, the machining operation of the cooling holes 15 may be faster and the productivity of the product may be improved.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
