(Figs. 1 to 11)
D shown in FIG. 1A is a fixing device, and the fixing device D abuts on the object W1 (FIGS. 5 to 11) to fix the object W1. The object W1 is, for example, a cross section. Is a circular pipe (work 1W1), which is used when the pipe is fixed by the fixing device D and, for example, the pipe (work 1W1) and the work 2W2 are welded and connected. The contact of the object W1 may be, for example, the inner wall of the object W1 (FIGS. 20 to 21) or the outer wall of the object W1 (FIGS. 22 to 23).

The contact members that come into contact with the object W1 are at least the first, second, and third contact members 1, 2, and 3.
Reference numeral 4 is a first member that supports one end of the first, second, and third contact members 1, 2, and 3, and reference numeral 5 is a first member facing the first member 4 and the first, second, and third members. It is a second member that supports the other ends of the third contact members 1, 2, and 3. The second member 5 has a communication passage 5a that communicates with the through hole 7a. Both ends of the second and third contact members 2 and 3 are supported by screws (not shown) via the first and second members 4 and 5.

Further, 6 supports one end surface of one of the plurality of contact members 1, 2, and 3 (for example, a contact member 1 having a diameter larger than the outer diameter of the contact members 2, 3). At the same time, it is a slide member slidably (slable) arranged on the first member 4 toward the second member 5.

As shown in FIG. 1, the first member 4 may be a single component (in the case of one component, a passage 4a through which the slide member 6 passes through the first member 4 and a female threaded portion screwed into the male threaded portion MB. It has 4b.).

Further, as shown in FIG. 3, the first member 4 may be two parts. In the case of two parts, the first member 4 has a first dividing member 41 having a passage 4a through which the slide member 6 passes, and a second dividing member 42 having a female screw portion 4b.

Further, as shown in FIG. 4, the first member 4 may be three parts. In the case of three parts, the first dividing member 41 communicates with the first dividing member 41'having an end passage 4c through which the end of the slide member 6 with which the moving member 6 abuts passes, and the end passage 4c. , A second split member 42 having a first "split member 41" having a passage 4a facing one end surface of one contact member 1 and two parts, and having a female threaded portion 4b in addition to the two parts. There are a total of three parts, one part.

Further, M is arranged on the first member 4, and when it abuts or does not abut on the slide member 6 and abuts, one end surface of one abutting member 1 toward the second member 5 is touched. An advancing / retreating moving member that moves in the pushing direction and maintains the moving state (the moving member is, for example, a screw, and other than the screw, it can be moved manually, by air, or by hydraulic pressure).
Reference numeral 7 is a support member arranged in the second member 5 that supports the other end surface of one contact member 1 and has a through hole 7a.
8 shown in FIG. 3 is a rod-shaped member that abuts on the other end surface of one abutting member 1 through the communication passage 5a and the through hole 7a.

Then, the first engaging surface 6A is attached to the tip of the slide member 6, the first engaging portion 1A is attached to one end surface of one contact member 1, and the second engaging surface 7B is attached to the tip of the support member 7. However, a second engaging portion 1B is formed on the other end surface of one contact member 1, the slide member 6 is moved by the moving member M, and the first engaging surface 6A is first engaged. By engaging the second engaging surface 7B with the second engaging portion 1B with the portion 1A, the first, second, and third contact members 1, 2, and 3 become the object W1. The object W1 is fixed by abutting against each other (FIGS. 20 to 21 when the object W1 is inscribed, and FIGS. 22 to 23 when the object W1 is circumscribed).

After fixing the object W1, for example, welding work is performed on the object W1. When the object W1 is released from being fixed by the fixing device D after the welding operation, the object W1 may be thermally deformed by the welding operation and the object W1 may not be easily detached from the fixing device D. Therefore, first, the moving member M is used to move the moving member M so as to be separated from one end surface of one contact member 1. Since no screw is formed on the slide member as in the conventional case, this movement can be smoothly performed because the screw is not damaged by the deformation (for example, thermal deformation) of the object W1.
By the movement of the moving member M, the restriction on the moving direction of one contact member 1 from the second member 5 to the first member 4 can be released. If one contact member 1 does not move from the second member 5 to the first member 4 even after this release, the rod-shaped member 8 is passed through the communication passage 5a and the through hole 7a to the other of the one contact member 1. By abutting and pushing the end face of, one contact member 1 is moved from the second member 5 to the first member 4, and the contact state between the one contact member 1 and the object W1. Can be released.

Therefore, according to the fixing device D (method of releasing the fixing device) described above, the slide member 6 is moved by the moving member M, and the first engaging surface 6A engages with the first engaging portion 1A. When the mating surface 7B engages with the second engaging portion 7B, the first, second, and third contact members 1, 2, and 3 abut on the object W1 to bring the object W1 into contact. In a fixed object, in order to release the fixation, the moving member M is moved so as to be separated from one end surface of one contact member 1, and after the movement, the rod-shaped member 8 is moved to the communication passage 5a and the through hole. By abutting against and pushing the other end surface of one contact member 1 via 7a, one contact member 1 is moved from the second member 5 toward the first member 4, and one hit. The contact state between the contact member 1 and the object W1 can be released.

Next, the following will be described with reference to FIGS. 5 to 11.

Z is a support device having a work 1W1, a work 2W2, a first part Z1, a second part Z2, and a third part Z3. It is erected between Z2 and the third part Z3 (see FIG. 6).
The fixing device D is inserted into the holes Z1a of the first portion Z1 and the holes of the work 1W1 (see FIGS. 7 to 9).
After insertion, the slide member 6 is moved by the moving member M so that the first engaging surface 6A engages with the first engaging portion 1A and the second engaging surface 7A engages with the second engaging portion 1B. By mating, the plurality of contact members 1, 2, and 3 come into contact with the inner circumference of the hole of the object W1 (see FIGS. 10, 20, and 21).
After the contact, the work 1W1 and the work 2W2 are welded, although not shown. After welding the work 1W1 and the work 2W2, the fixing device D must be released from the work 1W1.
Due to the thermal deformation of the work 1 W1, the fixing device D cannot be removed as it is, but as described below, one contact member 1 and the inner circumference of the hole of the object (work 1 is, for example, a pipe) W1. This is performed by releasing the contact state (see FIG. 11).
That is, the moving member M is moved so as to be separated from one end surface of one contact member 1, and this movement deforms the object W1 (for example, because the slide member is not formed with a screw as in the conventional case. , Thermal deformation) does not damage the screws, so it can be done smoothly.
If one contact member 1 does not move from the second member 5 to the first member 4 due to this movement, the rod-shaped member 8 is passed through the communication passage 5a and the through hole 7a to the other of the one contact member 1. By abutting and pushing the end face of, one contact member 1 is moved from the second member 5 to the first member 4, and the contact state between the one contact member 1 and the object W1. Can be released.

In the above-described embodiment, the rod-shaped member 8 is used, but the present invention is not limited to this, and the elastic member 10 shown in FIG. 12 may be used.

It has a member 10.

Then, as in the above-described embodiment, the first engaging surface (the first engaging surface is not shown in FIG. 12 but is described in FIG. 1) at the tip of the slide member (not shown). The engagement surface 6A of 1 is similar to that of the first engagement portion (the first engagement portion is not shown in FIG. 12) on one end surface of one contact member 1. However, the second engaging surface 7B is on the tip of the support member 7, and the second engaging surface 7B is on the other end surface of one contact member 1. Each of the engaging portions 1B of 2 is formed, and the sliding member (not shown) is formed by a moving member (the moving member is not shown in FIG. 13, but is, for example, the moving member M shown in FIG. 1). Moves so that the first engaging surface (not shown) engages the first engaging portion (not shown) and the second engaging surface 7B engages the second engaging portion 1B. As a result, the first, second, and third contact members 1, 2, (the third contact member is not shown in FIG. 12, but the third contact member described in FIG. 2A). The same as the member 3) comes into contact with the object W1 to fix the object W1.

A moving member (not shown) has a second engaging surface 7B formed at the tip of the support member 7 and a second engaging portion 1B formed at the other end surface of one contact member 1. The slide member (not shown) moves due to (not shown), the first engaging surface (not shown) becomes the first engaging portion (not shown), and the second engaging surface 7B becomes the first. By engaging with the engaging portion 1B of 2, the first, second, and third contact members 1, 2, (the third contact member is not shown in FIG. 12, but is not shown). The third contact member 3 described in FIG. 2A) is in contact with the object W1 to fix the object W1, and at that time, the elastic member 10 is contracted. ing.
Further, after fixing the object W1, welding work is performed on the object W1. When the object W1 is released from being fixed by the fixing device D after the welding operation, the object W1 may be thermally deformed by the welding operation and the object W1 may not be easily detached from the fixing device D. Therefore, first, using a moving member (the moving member is not shown in FIG. 12, for example, the moving member M shown in FIG. 1), a screw is formed on the slide member as in the conventional case. Since there is no damage to the screw due to deformation (for example, thermal deformation) of the object W1, a slide member (not shown) is used to move away from one end face of one contact member 1 (FIG. (Not shown) can be moved to move the first engaging surface (not shown). Along with this movement, the compressed and deformed elastic member 10 is released. Therefore, the elastic member 10 pushes the other end face of one contact member 1 to make one contact member 1 a second member. By moving from 5 to the direction of the first member (not shown), the contact state between one contact member 1 and the object W1 can be released.

Further, although the elastic member 10 is used in the above-described embodiment, the present invention is not limited to this, and the rod-shaped member 8'and the elastic member 10'shown in FIG. 13 may be used. Although the illustration on the right side from the center of the fixing device D is omitted in FIG. 13, the right side omitted from the center of FIG. 13 has the same configuration as the right side from the center of the fixing device D in FIG. ..

The object W1 can be fixed, and at that time, the elastic member 10'is contracted.
Further, after fixing the object W1, welding work is performed on the object W1. When the object W1 is released from being fixed by the fixing device D after the welding operation, the object W1 may be thermally deformed by the welding operation and the object W1 may not be easily detached from the fixing device D. Therefore, first, a screw is formed on the slide member as in the conventional case by using a moving member (the moving member is not shown in FIG. 13, but is, for example, the moving member M shown in FIG. 1). Therefore, it is possible to move the object W1 so as to be separated from one end face of the contact member 1 by the amount that the screw is not damaged by the deformation (for example, thermal deformation) of the object W1. Along with this movement, the compressed and deformed elastic member 10'is released. Therefore, the elastic member 10'pushes the other end face of one contact member 1 by the rod-shaped member 8', and one contact is made. The member 1 can be moved from the second member 5 toward the first member 4, and the contact state between one contact member 1 and the object W1 can be released.

Further, in the above-described embodiment, the rod-shaped member 8'and the elastic member 10' are used, but the present invention is not limited to this, and the first and second elastic members 10 "shown in FIGS. 14 and 15". You may use 10 "'.

That is, the fixing device D in this case is a fixing device D that abuts on the object W1 and fixes the object W1, and at least the first, second, and third abutments that abut on the object W1. The members 1, 2, and 3, the first member 4 that supports one end of the first, second, and third contact members 1, 2, and 3, and the first member 4 facing the first member 4 and the first member.

A slide member 6 that supports one end surface of one of the members 1, 2 and 3 and is slidable toward the second member 5 and is arranged on the first member 4. It has a moving member M that is in contact with the slide member 6, moves toward the second member 5, and can move forward and backward to hold the moving state.

The first elastic member 10 "is connected to the first contact member 1 and the second contact member 2, and the second elastic member 10" "is connected to the first contact member 1 and the third contact member 2. It is connected to the contact member 3 of.

Then, as in the above-described embodiment, the first engaging surface 6A is attached to the tip of the slide member 6, the first engaging portion 1A is attached to one end surface of one contact member 1, and the tip of the support member 7 is attached. A second engaging surface 7B is formed on the surface, and a second engaging portion 1B is formed on the other end surface of one contact member 1, and the slide member 6 is moved by the moving member M to engage in the first engagement. By engaging the surface 6A with the first engaging portion 1A and the second engaging surface 7B with the second engaging portion 1B, the first, second, and third contact members 1, A few come into contact with the object W1 to fix the object W1.
Further, FIGS. 15 (a) and 15 (b) show the inner circumference of the object W1, and FIGS. 15 (c) and 15 (d) show the outer circumference of the object W1 in contact with each other.
In FIGS. 15 (c) and 15 (d), the first contact member 1 is located above the second contact member 2 and the third contact member 3, but the second contact member 1 is desirable. It is preferable that the first contact member 1 is located below the contact member 2 and the third contact member 3 (see FIGS. 22 to 23).

Therefore, according to the fixing device D described above, the first engaging surface 6A is attached to the tip of the slide member 6, and the first engaging portion 1A is attached to one end surface of one contact member 1 of the support member 7. A second engaging surface 7B is formed at the tip thereof, and a second engaging portion 1B is formed at the other end surface of one contact member 1, and the slide member 6 is moved by the moving member M to engage in the first engagement. By engaging the mating surface 6A with the first engaging portion 1A and the second engaging surface 7B with the second engaging portion 1B, the first, second, and third contact members 1 2, 3 abut on the object W1 [FIG. 15 (a) (b) in the case of inscribed figure, FIG. 15 (c) (d) in the case of inscribed figure] to fix the object W1. At that time, the first and second elastic members 10 "10""are compressed and deformed.
After fixing the object W1, welding work is performed on the object W1. When the object W1 is released from being fixed by the fixing device D after the welding operation, the object W1 may be thermally deformed by the welding operation and the object W1 may not be easily detached from the fixing device D. Therefore, first, since the screw is not formed on the slide member by using the moving member M as in the conventional case, one contact is made because the screw is not damaged by the deformation (for example, thermal deformation) of the object W1. It can be moved so as to be separated from one end surface of the member 1. Along with this movement, the compressed and deformed elastic members 10 "10""are released. Therefore, the elastic members 10" and "10""move one abutting member 1 to its original position. The contact state between one contact member 1 and the object W1 can be released.

It has a support member 7 and a support member 7.

The slide member 6 has a body portion 61 that is long in the longitudinal direction and a head portion 62 that is connected to the body portion 61 and projects outward, and the head portion 62 is exposed to the outside and is in contact with one. It is an end portion on the side far from one end surface of the member 1, and has an inclined surface 62K toward the body portion 61.
