[0010]

Embodiments of the present invention will be described below with reference to the drawings.

(Outline) The pipe end processing machine of the present invention is used to cut the pipe 1 at a predetermined position or to machine the cut end. The outline of the pipe end processing machine of the present invention is as shown in FIG. 1, and is mainly fixed to a support portion A inscribed in the pipe 1 and a substantially coaxial core with the axis 1X of the pipe 1 by the support portion A. A shaft member B, a rotating portion C rotatable around the shaft member B, and a processing means D provided at the tip of the rotating portion C for processing the end surface of the pipe 1.
By appropriately selecting a grinder or a gas cutting torch as the processing means D, the pipe 1 can be machined or thermally cut. In the present embodiment, particularly, an example is shown in which an already cut pipe end is polished to form a welding groove in order to weld the pipes 1 to each other.

(Supporting part) The supporting part A is a part for supporting the pipe end processing machine of the present invention with respect to the pipe 1. That is,
For example, as shown in FIG. 1, the inside of the pipe 1 is configured in a pantograph type so as to be able to contact three places. That is, the first base member 2 and the second base member 3 are attached to the shaft member B, and the support link member 4 is attached thereto. The shaft member B is constituted by a male screw member, and the first base end member 2 is loosely fitted to an end of the shaft member B. That is, the first base member 2 is rotatable with respect to the shaft member B, and is not movable in the direction of the shaft center BX of the shaft member B. On the other hand, the second base member 3 is constituted by a female screw member which can be screwed to the shaft member B. The first
Three supporting link members 4 are attached to the base member 2 and the second base member 3. Each support link member 4
Extending in the radial direction Y when viewed in the axial direction of the shaft member B,
In addition, the angle between the support link members 4 is approximately 1
Mount so that it is at 20 degrees. A mounting portion between each of the first base member 2 and the second base member 3 and the support link member 4 is a pivot portion. In other words, by rotating the support handle 5 attached so as to rotate integrally with the shaft member B in any direction, and rotating the shaft member B around its own axis BX, the second base The end member 3 is moved toward and away from the first base end member 2. When both are brought close to each other, the support link member 4 extends outward with respect to the shaft member B, presses the inside of the pipe 1, and fixes the support portion A inside the pipe 1. Can be. In order to release the pressing of the support link member 4, the support handle 5 may be rotated in the opposite direction.
When the support portion A is fixed inside the pipe 1, if the rotation portion C and the processing means D, which will be described later, are removed, the overall weight is reduced and the mounting operation is facilitated. .

(Shaft Member) As shown in FIG. 1, the shaft member B includes a support shaft member 6 supported by the support portion A, a rotation shaft member 7 provided with a rotation portion C described later, It comprises a swing connection member R for connecting the support shaft member 6 and the rotating shaft member 7 while adjusting the relative angle arbitrarily. The support shaft member 6 is formed of, for example, a male screw member as described above. On the other hand, the rotation shaft member 7 is formed of, for example, a member having a smooth cylindrical surface. A rotating portion C described later is slidably attached to the cylindrical surface along the direction of the axis 7 </ b> X of the rotating shaft member 7.

The cut end face 1a of the pipe 1 is the axis 1X of the pipe 1.
Is formed at right angles to the cut end face 1
In order to process a, it is desirable that the support shaft member 6 and the rotating shaft member 7 are positioned on the same axis. Thereby, the processing means D attached to the tip of the rotating portion C can rotate along the cut end surface 1a of the pipe 1. In order to achieve this configuration, the support shaft member 6 and the rotation shaft member 7 may be configured as a single member. But,
When the cut end face 1a of the pipe end is formed to be inclined with respect to the axis of the pipe 1, the processing means D attached to the tip of the rotating part C rotates along the cut end face 1a. In order to be able to move, it is necessary to make the axis 7X of the rotating shaft member 7 coincide with the normal direction of the cut end surface 1a. for that reason,
In the pipe end processing machine of the present invention, the support shaft member 6 and the rotation shaft member 7 are connected using a swing connection member R, and the angle between both shaft members B can be adjusted. .

As shown in FIG. 2, the swing connection member R includes a first member 8 attached to an end of the support shaft member 6.
And a second member 9 attached to the end of the rotating shaft member 7. The first member 8 has a first abutting surface 8a inclined with respect to a direction perpendicular to the axis 6X of the support shaft member 6.
And the second member 9 is provided with a shaft core 7 of the rotating shaft member 7.
It has a second butting surface 9a inclined with respect to a direction perpendicular to X. In the present embodiment, each inclination angle is set to, for example, 3 degrees. The first member 8 and the second member 9 each have a flange portion for connection. Here, the one provided on the first member 8 is referred to as a first flange portion 8f, and the one provided on the second member 9 is referred to as a second flange portion 9f. For example, the first flange portion 8
f, holes 11 through which the connecting bolt member 10 can be inserted on both sides in the radial direction Y with respect to the center position of the first butting surface 8a.
Is provided. That is, two connecting bolt members 10 are attached to the first member 8. As shown in FIG. 2, the second flange portion 9f of the second member 9 is provided with a pair of angle adjusting holes 12 at positions opposed to each other across the center position of the second butting surface 9a. The angle adjusting hole 12 is shown in FIG.
, A pair is provided in a quarter arc shape. Note that the angle adjustment in this case refers to adjusting the angle between the axis 6X of the support shaft member 6 and the axis 7X of the rotation shaft member 7. FIG. 3 shows the relationship between the two connecting bolt members 10 and the angle adjusting holes 12. Now, it is assumed that the positional relationship between the two connecting bolt members 10 coincides in the vertical direction. A pair of angle adjusting holes 12 are externally inserted into the respective connecting bolt members 10, and the second bolt 9 is inserted from the side of the second member 9 along the direction of the axis 7 </ b> X of the rotating shaft member 7.
FIG. 3 shows a state in which the second member 9 is fully rotated counterclockwise when the member 9 is viewed. In this state, the shaft center 6X of the support shaft member 6 and the shaft center 7X of the rotation shaft member 7
Is assumed to match. Since the normal line 9Z of the second butting surface 9a and the axis of the rotating shaft member 7 have an angle of about 3 degrees, the second member 9 is rotated clockwise from the state of FIG. Then, the free side end of the rotating shaft member 7 moves upward and to the left in an arc. When the second member 9 is rotated approximately 90 degrees clockwise, the support shaft member 6 is rotated.
The angle formed between the shaft core 6X and the shaft core 7X of the rotating shaft member 7 is about 3 degrees. Note that this angle is not exactly 3 degrees. That is, the angle between the axis 7X of the rotating shaft member 7 and the normal 9Z of the second butting surface 9a is 3 degrees, but the normal 9Z is relative to the axis 6X of the support shaft member 6. This is because it has an angle of 3 degrees. If the angle between the axis 6X of the support shaft member 6 and the axis 7X of the rotary shaft member 7 is to be set to be larger, the second member 9 is temporarily removed from the first member 8 and the own member is removed. It is turned 180 degrees around the axis 7X and attached to the first member 8 again. In this case, at the position where the rotation shaft member 7 is fully rotated in the counterclockwise direction, the angle between the axis 6X of the support shaft member 6 and the axis 7X of the rotation shaft member 7 is 6 degrees. Degree. Conversely, at the position where the rotating shaft member 7 is fully rotated clockwise, the angle between the axis 6X of the supporting shaft member 6 and the axis 7X of the rotating shaft member 7 is about 3 degrees. Become.

As described above, when the angle between the support shaft member 6 and the rotating shaft member 7 has been adjusted, the extending direction of the rotating shaft member 7 actually matches the intended direction. Not necessarily. Therefore, the first member 8 is rotated around the axis 6 </ b> X of the support shaft member 6 to adjust the extending direction of the rotation shaft member 7. That is, as shown in FIG. 2, the first member 8 is screwed into the tip of the support shaft member 6 with the swinging direction adjustment bolt 13 screwed near the end of the support shaft member 6. It is sandwiched between male threads 14. By loosening the swinging direction adjusting bolt 13, the first member 8 becomes rotatable around the axis 6 </ b> X of the support shaft member 6, so that the extending direction of the rotation shaft member 7 can be arbitrarily set. Can be set. As shown in FIG. 3, an angle scale 15 is provided around the first member 8 and a second
An index is provided around the member 9. That is, the second member 9
The angle between the support shaft member 6 and the rotation shaft member 7 can be set by setting the index of the above to an arbitrary position of the angle scale 15. As shown in FIG. 2, a level ring 17 is provided around the first member 8 so as to be rotatable around the first member 8. A weight member 18 is provided below the level ring 17. That is, the index 19 of the level ring 17
Always indicates the direction above the axis 6X of the support shaft member 6 in the vertical direction. Thus, the extension direction of the rotation shaft member 7 is determined by appropriately positioning the index 19 and the angle scale 15. can do.

(Rotating Part) The rotating part C is configured to be rotatable around the rotating shaft member 7, and a processing means D attached to the tip of the rotating part C is provided on the pipe 1. Cutting end surface 1a
This is a mechanism for rotating along. Therefore, the rotation portion C is configured to be freely adjustable in the direction of the axis 7 </ b> X of the rotation shaft member 7 and to be rotatable with respect to the rotation shaft member 7. The rotating part C is, as shown in FIG.
Mainly, a slide tube member 20 slidably inserted outside the rotary shaft member 7, a slide tube member 21 similarly slidably inserted outside the slide tube member 20, Fixed to the outer periphery of the slide cylinder member 21 via a bearing 22;
It comprises a rotating arm 23 rotatable around the slide cylinder member 21.

The sliding cylinder member 20 is a substantially cylindrical member and has an inner diameter slightly larger than the outer periphery of the rotating shaft member 7. The sliding shaft member B is rotatable around the axis 7X of the rotating shaft member 7 with respect to the outer peripheral surface of the rotating shaft member 7, and extends along the extending direction of the shaft core 7X. It is movable. As shown in FIG. 5, an end of the sliding cylinder member 20 is provided with a grip portion 2 for fixing to the rotating shaft member 7.
0a is provided. The grip portion 20a is notched in the circumferential direction of the shaft core 7X of the rotating shaft member 7. Further, the notch portion 20b is provided with a pair of opposed flange portions 20f.
The sliding cylinder member 20 can be fixed to an arbitrary position of the rotation shaft member 7 by fastening or loosening the f using the first fixed handle 24 having a screw member. According to this configuration, even if the projecting length of the rotation shaft member 7 from the end of the pipe 1 changes, the position of the rotation part C is easily set in accordance with the end of the pipe 1. be able to.

As shown in FIG. 4, a slide cylinder member 21 is provided outside the slide cylinder member 20 so as to constitute the position adjusting means E of the rotary arm 23. The slide cylinder member 21 is movable along the longitudinal direction of the slide cylinder member 20, and is used when finely adjusting the position of the rotating portion C with respect to the end surface 1 a of the pipe 1. The position adjusting means E further includes a fine adjustment bolt 25 and a fine adjustment handle 26 screwed into the grip portion 20a in the same direction as the axis 7X of the rotating shaft member 7, and the slide cylinder member 21.
And a pressing portion 27 provided at an end portion of the light emitting device. That is, after the sliding cylinder member 20 is fixed, the position of the sliding cylinder member 21 is finely adjusted by rotating the fine adjustment handle 26 right and left. In this case, the fine adjustment handle 26 operates only when the slide cylinder member 21 is pushed into the pipe 1 side. That is, when the fine adjustment handle 26 is pushed into the pipe 1, the fine adjustment bolt 25 comes into contact with the pressing portion 27 of the slide cylinder member 21 and pushes the slide cylinder member 21 toward the pipe 1. be able to. But,
When the fine adjustment handle 26 is pulled in the direction opposite to the pipe 1, the fine adjustment bolt 25 is
, The slide cylinder member 21 does not operate. In this case, an operator holds the rotating arm 23 and the like and separates it from the pipe 1. The fine adjustment handle 26 is a mechanism for gradually feeding the processing means D toward the end face 1a of the pipe 1 when polishing the end face 1a of the pipe 1 using the processing means D. The function is fully demonstrated in the configuration.

The rotary arm 23 is rotatably mounted on the outer peripheral portion of the slide cylinder member 21 via a bearing 22. That is, the rotating portion C can be rotated around the axis 7X of the rotating shaft member 7 by a manual operation of the operator. With this configuration, the configuration of the pipe end processing machine can be made very simple. Of course, a drive mechanism may be attached to automatically operate the rotating portion C.

As shown in FIG. 4, the rotary arm 23 is provided with a processing means mounting member 28 for mounting the processing means D. The rotary arm 23 has an elongated hole 29 as shown in FIGS. A top member 30 is inserted from one side of the long hole 29, and a mounting angle selecting member 28a is formed as a processing means mounting member 28 on the other side.
And a second angle is attached to the mounting angle selecting member 28a.
The male screw portion 31a is screwed into the top member 30 while the male screw portion 31a of the fixed handle 31 is inserted. In this case, since the top member 30 is inserted into the long hole 29 so as not to rotate, the top member 30 does not rotate together when the male screw portion 31a is screwed. The mounting angle selecting member 28a has two grooves 28b for fitting the rotary arm 23 therein. These grooves 28b have an angle of 30 degrees with each other.
That is, when the rotary arm 23 is mounted on one of the grooves 28b, the polishing surface of the grinder is perpendicular to the axis 1X of the pipe 1. And the other groove 28b
When the rotating arm 23 is mounted on the shaft 1, the normal of the polished surface of the grinder passes through the axis 7X of the rotating shaft member 7, and the normal of the grinder is adjusted to the axis 1 of the pipe 1.
Tilt about 30 degrees to X. In this case, a welding groove having an angle of 30 degrees can be formed on the end face 1a of the pipe 1. FIG. 7 shows these states. When changing the mounting angle of the mounting angle selecting member 28a,
This is performed while holding the holding portion 32 attached to the attachment angle selecting member 28a. In the present embodiment, the angle set by the mounting angle selection member 28a is limited to two types.
It may be configured so that it can be set in multiple stages.
If the member relating to the rotating portion C is made of, for example, an aluminum material, the weight can be reduced, and the mounting work and the actual driving work of the device become easy.

(Mounting of processing means) Although illustration is omitted,
The processing means D such as a grinder can be attached to the attachment angle selecting member 28a via various jigs. In that case, the angle of the polished surface of the grinder can be freely adjusted, so that the operability of the present apparatus can be further improved.

(Effects) As described above, according to the pipe end processing machine of the present invention, the rotating shaft member 7 which is the axis for rotating the processing means D such as a grinder is moved with respect to the cut end face 1a of the pipe 1. Since it can always be set vertically, the pipe end can be machined accurately. Moreover, since the pipe end processing machine is mounted while being pressed against the inner surface of the pipe 1, it can be easily performed even in a narrow work space, and the pipe end processing of the pipe 1 can be performed quickly and accurately. It can be carried out.

[Another Embodiment] <1> In the above embodiment, the connection between the first member 8 and the second member 9 relating to the swing connection member R is performed by the first flange portion 8f.
And the second flange 9f are connected by the connection bolt member 10, but the present invention is not limited to this configuration, and may be configured as shown in FIG. That is, the first member 8
A universal joint 33 is provided between the second member 9 and the second member 9.
The universal joint 33 includes a ball seat 33a provided at a central portion and a plurality of push screw members 33b provided at side portions thereof. If the degree of screwing of these plurality of screw members 33b is adjusted, the second member 9 can be adjusted as in the above embodiment.
The relative angle between the first member 8 and the second member 9 can be changed only by adjusting the fastening force of the push screw member 33b without any trouble such as once removing the The angle of the shaft member 7 can be quickly adjusted.

<2> Further, the configuration of the swing connection member R can be configured as shown in FIG. That is, the penetrating member 35 is provided on the same axis as the rotating shaft 34 for relatively rotating the first butting surface 8a of the first member 8 and the second butting surface 9a of the second member 9. In FIG. 8, the penetrating member 35 is constituted by, for example, a bolt member 35a,
The structure which penetrates the said 1st member 8 and the said 2nd member 9 and fastens both members is shown. Of course, the penetrating member 35
As long as the first member 8 and the second member 9 can be fastened, only one of the members may be penetrated. With this configuration, the first butting surface 8a and the second butting surface 9a are merely reduced by reducing the fastening force of the penetrating member 35.
a can be relatively rotated, so that the angle of the rotation shaft member 7 can be quickly adjusted.
