Description

Technical Field [0001] The present invention relates to a co-

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe surface coordinate display apparatus, and more particularly, to a pipe surface coordinate display apparatus and, more particularly, to a pipe surface coordinate display apparatus, And more particularly, to a pipe surface coordinate display apparatus which can accurately display coordinate positions of holes.

Generally, to connect another pipe to a pipe, one or more holes should be drilled on the surface of the pipe. For this purpose, the position of the hole to be drilled should be accurately displayed on the surface of the pipe. Until now, such a display operation is entirely dependent on the manual operation, so that the accuracy of the operation is lowered and the work efficiency is not high.

That is, as shown in Fig. 1, in order to drill a hole on the surface of the pipe P, a marking operation to indicate the position of the hole on the surface must precede the drilling operation. However, as shown in Fig. 1, the display operation is based on manual operation. For example, an axis line direction coordinate is drawn by drawing a straight line in the axial direction from the reference point, and the mirror point gauge ( 101 to move the target point P2 in the circumferential direction by a desired angle. At this time, the worker can confirm the moving angle by the indicating needles of the mirror point gauge 101.

In this way, the operator can display the target point P2 at a position distant from the reference point by a predetermined distance and angle on the surface of the pipe P. Conventionally, the above-described target point P2 display operation is performed, for example, In the case of the circumferential direction coordinate point P2 in which the diagonal direction coordinate point P2 is used, the operation time of the display operation becomes long and the work efficiency is decreased, for example, the work efficiency is lowered by the manual operation using the mirror point gauge 101 .

Further, since the target point P2 is difficult to be displayed at the correct position by the above-described manual operation and the display gold L displayed by the food line is not accurate, the perforation position of the holes to be drilled in the drilling operation thereafter is not accurate, Therefore, there is a problem that the quality of the pipe after the perforation is greatly deteriorated.

The present invention has been proposed in order to solve the problem of the conventional coordinate display method on the surface of the pipe, and it has been proposed to display the position of the hole in order to drill a plurality of holes on the surface of the pipe, The objective of the present invention is to improve the accuracy of the coordinate display result as well as the efficiency of the coordinate display operation by accurately and simply indicating the position of each hole in the casing.

In order to achieve the above object, the present invention provides a method of controlling an angle of a pipe by grasping one end of a pipe to be angularly displayed, rotating the pipe by an index handle, and determining an angle of rotation of the pipe by an angle- Can index chuck; And an indicator arranged in a radial direction perpendicular to an axial direction of the index chuck, the indicator indicating a mark on the surface of the pipe.

The display device may further include: a display unit that contacts the surface of the pipe to draw the display gold on the surface; And a support plate movably supporting the indicator in the radial direction.

The supporting plate may include a waveguide for holding and supporting the display unit; And a plate body for supporting the wave earth movably in the radial direction.

Further, the wave guide may include: a gripper for directly gripping and fixing the indicator; And a guide portion movably supporting the grip portion in a vertical direction perpendicular to the axial direction and the radial direction.

Further, it is preferable that the apparatus further includes a base supporting the indicator at a position adjacent to the pipe, and the base includes a guide rail extending along the axial direction so as to movably support the indicator in the axial direction .

The apparatus of claim 1, further comprising a pedestal provided in contact with the bottom of the pipe for supporting the pipe together with the index chuck, the pedestal having a height varying with the diameter of the pipe, As shown in Fig.

According to the pipe surface coordinate display apparatus of the present invention, the target pipe to display the center coordinates of the perforation hole is stuck to the index chuck, the zero point of the pipe is taken in the rotating direction, and the display is placed at the reference point on the pipe side line Since the center of the hole to be drilled can be displayed at a coordinate position that is as far as desired from the reference point of the pipe surface simply by moving the indicator in the axial direction and rotating the pipe by the desired angle with the index handle, Very fast and convenient.

In this process, since the axis movement of the display or the rotation of the pipe is accurately performed by the indicator or the index chuck, the accuracy of the coordinates moved from the reference point to the target point can be greatly increased, The positions of the respective holes can be accurately maintained during the drilling operation, and as a result, the quality of the pipe produced by the drilling operation can be further improved.

Fig. 5 is a diagram showing a state in which the display sphere is moved to the x-axis coordinate position of the target point, and Fig.

Hereinafter, a pipe surface coordinate display apparatus according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The coordinate display apparatus according to the present invention comprises an index chuck 3 and a display unit 5 as shown in FIG. 2 and FIG. 3 as a reference numeral 1 and includes a base 7 and a pedestal 9 .

Here, the index chuck 3 is a means for grasping and rotating the indicator P shown in FIG. 4 by the pipe P as shown in FIG. 2 and FIG. 3, Is mounted on the support (11). Therefore, the index chuck 3 grasps one end of the pipe P at which the coordinates are to be displayed at a certain height apart from the ground surface. By rotating the index handle 13 in the forward and reverse directions, Rotate in both directions. 2, the index chuck 3 is arranged not only in the circumferential direction on the rear surface of the chuck body 15 but also in the case 19 (see FIG. 2) in contact with the chuck body 15, The rotational angle of the body 15 relatively rotating with respect to the case 19 is visually confirmed through comparison of the angle division scale 17 and the reference mark 21, To be measured. Accordingly, the operator can adjust the y-axis coordinate value of the hole (perforation hole) to be drilled in the outer wall of the pipe P in the subsequent process from the pipe P surface As shown in FIG.

2 and 3, the display device 5 includes a display panel 23 and a support plate 25. The display panel 5 is provided with a pipe P, The display mark L is drawn or the display screen 23 is moved to a position spaced a desired distance in the axial direction (the direction of arrow A in FIG. 2) from the reference point O at the front surface of the surface, that is, in the x-axis direction. Therefore, the operator can determine the x-axis coordinate value of the coordinates of the perforation hole to be processed on the outer wall of the pipe P in the subsequent process to the surface of the pipe P in accordance with the distance that the pipe P moves from the reference point O in the axial direction It becomes possible to display it. 2 and 3, the indicator 5 is arranged at a right angle to the axial direction A of the index chuck 3 so that the indicator 23 can be brought into contact with or spaced from the surface of the pipe P. [ That is, in the radial direction of the pipe P (the direction of the arrow B in Fig. 3).

Here, the indicator 23 is a part of the upper display 5 that directs display gold L to the surface of the pipe P, and as shown in Figs. 2 to 4, The contact with the surface of the pipe P is maintained from the reference point O to the end of the display gold L when the display gold L is drawn. However, when the display unit 23 is moved only from the reference point O to a desired point, i.e., an x-axis coordinate point, the display unit 23 naturally remains apart from the surface of the pipe P. [ The pipe P is adjusted to the zero point of the angle dividing scale 17 and the reference mark 21 before the indicator 23 is first brought into contact with the reference point O on the pipe P. [

The support plate 25 is a means for movably supporting the indicator 23 in the radial direction B of the pipe P so that the indicator 23 can be moved in the radial direction B As shown in Figs. 2 and 3, in the present embodiment, it is possible to move the waveguide 27 holding the indicator 23 in the radial direction B with respect to the plate body 29 . The supporting plate 25 is composed of a waveguide 27 and a plate 29. The waveguide 27 is supported on the plate 29 so as to be movable in the radial direction B, As shown in Fig. The operator adjusts the distance between the tip of the indicator 23 and the surface of the pipe P according to the diameter of the pipe P by moving the tread 27 in the radial direction B above the plate 29 . As described above, the plate body 29 is a support means for movably supporting the wave earth 27 in the radial direction B, as described above. Although not shown in the figure, So as to guide the movement of the waveguide 27 in the radial direction B and fix the waveguide 27 moved to the desired position by the fixing bar 31. [

The waveguide 27 is formed so as to move the indicator 23 in the vertical direction (the direction of the arrow C in Fig. 3) perpendicular to the axial direction A and the radial direction B, The guide portion 35 and the guide portion 33 can be distinguished. Here, the grip portion 33 is a portion for gripping and fixing the display screen 23 directly, particularly the display screen 23, as shown in Figs. 2 and 3, (37) for detachably fixing the body (23) and a connecting block (39) for connecting the catch (37) to the guide portion (35). At this time, the connecting block 39 is detachably attached on the guide portion 35 by a fastening screw. The guide portion 35 is a portion that supports the grip portion 33 in the vertical direction C so as to be movable in the vertical direction C as shown in FIGS. , And guides the lifting and lowering of the gripper (33). Therefore, the operator again elevates the grip portion 33 in the up and down direction C along the guide portion 35 to move the height of the indicator 23, which is held by the catch 37 of the grip portion 33, (P).

2 and 3, the base 7 is a support frame for supporting the display device 5 constructed as described above so that it can come to a position adjacent to the pipe P bite in the index chuck 3, A guide rail 41 is provided on the upper end surface of the display unit 5 so as to movably support the display unit 5 in the axial direction A through the support plate 25. At this time, since the guide rail 41 is elongated along the axial direction A, it guides the movement of the display device 5 in the axial direction A. Therefore, the operator moves the entire display device 5 in the axial direction A The display mark L in the axial direction A can be drawn on the surface of the pipe P and the position of the display screen 23 in the axial direction A can be changed. At this time, the distance from the reference point O to the end point of the display gold L, that is, the x-axis coordinate point of the center of the perforation hole may be measured using a separate measuring means such as a tape measure. It is possible to confirm the moving distance of the display device 23 without using a separate measuring means by disposing a scale indicative of the length such as a tape measure in the axial direction A on the upper surface of the base 7. [

The pedestal 9 is a means for supporting the pipe P in an auxiliary manner together with the index chuck 3. The pedestal 9 is preferably a means for supporting the pipe P so as to come into contact with the bottom surface of the pipe P, (7). At this time, the pedestal 9 is variable in height according to the diameter of the pipe P so as to support the pipes P having various diameters irrespective of the diameter deviation, so that the pedestal 9 maintains contact with the pipe P. To this end, the pedestal 9 may employ various types of height-varying structures, in which a scissor lift 43 is used, as shown. The worker adjusts the height of the scissor lift 43 in accordance with the diameter of the pipe P, that is, the distance from the base 7 to the pipe P so as to support the pipe P by the pedestal 9 . At this time, the pedestal 9 is provided with the rolling wheels 45 at the point of contact with the pipe P, thereby minimizing the resistance to the pipe P by the contact with the pedestal 9 when the pipe P is rotated .

Now, the operation of the pipe surface coordinate display apparatus 1 according to the preferred embodiment of the present invention will be described as follows.

In order to display the center coordinates of the hole to be drilled on the surface of the pipe P by the pipe surface coordinate display device 1 of the present invention, first, as shown in Figs. 2 and 3, And is stuck to the chuck body 15 by using the holding jig 16 of the index chuck 3.

Next, the index handle 13 is turned, and the body 15 is relatively rotated with the pipe P with respect to the case 19 so that the zero point of the angle division scale 17 formed on the body 15 becomes the case 19) with the reference mark (21).

The display device 5 is then moved from the reference point O and the support plate 25 is moved along the guide rail 41 in the axial direction A after primarily aligning the display window 23 with the reference point O. [ That is, in the x-axis direction. At this time, the distance of the display mark 23 of the display device 5 from the pipe P to the distance of the display mark L or the distance from the pipe P is smaller than the distance from the pipe P to the perforation hole Axis coordinate value among the center-point coordinate values of the x-axis coordinate values.

However, in this step, the display tip of the display means 23 is moved to the side line of the pipe P, that is, The horizontal surface including the pipe (P) axis and the pipe (P) surface should be at the same height as the meeting line. To this end, the grip portion 33 of the tread portion 27 is loosened and then moved along the guide portion 35 in the vertical direction C, that is, in the z-axis direction so as to come to the height corresponding to the side line, And fixed on the guide portion 35. It is also possible to display the display mark 23 on the surface of the pipe P in the axial direction A or on the surface of the pipe P only by moving the display screen 23 apart from the surface of the pipe P The display bar 23 is moved in the radial direction B, that is, in the y-axis direction. After the fixing bar 31 is released and the display bar 23 is moved in the radial direction B on the support plate 25 , So that the tip of the indicator (23) is brought into contact with or spaced from the surface of the pipe (P), that is, the side of the pipe (P). Then, when the position of the tip of the indicator 23 is finely adjusted again in the xyz axis direction so that the indicator 23 is accurately positioned on the reference point O, the indicator 23 is ready to move.

When the operator pushes the index handle 13 of the index chuck 3 and moves the pipe P in the axial direction A in the axial direction A, For example, in the direction of the arrow R in Fig. At this time, the operator confirms that the angle dividing scale 17 gradually rotates at the zero point of FIG. 2, and stops rotating when the rotation angle scale of 30 degrees coincides with the reference mark 21, P) by the corresponding angle, that is, 30 degrees. Therefore, the indicator 23 moves relatively along the imaginary path T in the circumferential direction of the pipe P, and after relatively rotating by a predetermined angle, that is, by 30 degrees, as shown in FIG. 5, Axis coordinate of the center of the perforation hole on the surface of the phosphorus pipe P.
