DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressing / holding jig for attaching an attached object such as a thin plate or a film to a structure.

[0002]

2. Description of the Related Art Conventionally, when a material such as a strain gauge is attached to a structure, an operator presses the material with hand or puts a weight on the material and presses it. Was the mainstream. However, when the surface of the structure is not horizontal and has a certain inclination, it is often impossible to put a weight on it, and there is a limit to the magnitude of the force and the like even in pressing by hand. On the other hand, when performing the work of attaching the affixed material to such a structure, there is no suitable holding jig for securely holding the attached material.

[0003]

However, as described above, in the method in which the patch is pressed by the operator with hand power, it is impossible to press the patch with a constant force for a long time, and the quality of the patch is reduced. It cannot be kept constant. In addition, when the surface to which the patch is to be attached is not horizontal, it is impossible to place a weight or the like and press it, and it is impossible to press it with human hands for a long time.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to easily and efficiently attach an object such as a strain gauge regardless of whether the surface of the structure to which the object is to be attached is flat or curved. An object of the present invention is to provide a holding jig which has excellent ability and can stably press and hold a target place for a long time.

[0005]

Means for Solving the Problems The present inventors have conducted intensive tests from the above viewpoints.

[0006] First, it is possible to hold down a predetermined attached object with a required constant force for an arbitrary long period of time, and furthermore, the pressing force is reduced according to a designated attaching position on the surface of a predetermined structure. Because of the need to be able to load, we focused on the production of a jig provided with an appropriate pressing force adjustment mechanism and holding part adjustment mechanism. In order to further exert the functions of the pressurizing force adjusting mechanism and the holding portion adjusting mechanism, the two mechanisms are integrated, and the relative positional relationship between the two mechanisms with respect to the structure can be fixed. We focused on the need for a special mechanism. The present invention has been made based on the above idea, and its gist is as follows.

According to a first aspect of the present invention, there is provided a holding jig for attaching an adhered object such as a thin plate or a film to a flat or curved structure or a structure having a flat and curved surface. This jig is characterized by having three mechanisms.
That is, a pressing force adjusting mechanism having a function of adjusting a force for pressing the attached object to the structure, and three-dimensionally adjusting a position for pressing the attached object when pressing the attached object to the structure. It is characterized by comprising a holding part adjusting mechanism having a function, and a holding jig fixing mechanism having a function of attaching the holding jig to the structure in a fixed form.

According to a second aspect of the present invention, in the holding jig according to the first aspect of the present invention, a screw mechanism is provided as a pressing force adjusting mechanism. A mechanism is provided, and an adjustment groove using a position adjustment groove is provided for horizontal adjustment, and as a holding jig fixing mechanism, the fixing force to the structure is reduced to atmospheric pressure and vacuum. The present invention is characterized in that any one of a vacuum suction mechanism, a magnetic suction mechanism, and an adhesion mechanism utilizing a pressure difference from pressure is provided.

According to a third aspect of the present invention, in the holding jig of the second aspect, the holding portion adjusting mechanism is further provided with a spherical joint for height and horizontal adjustment. It has features.

[0010]

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a schematic perspective view for explaining an example of an embodiment of a jig for holding a patch according to the present invention. Reference numeral 1 denotes a structure, reference numeral 2 denotes an adhered object, and reference numeral 3 denotes a holding jig. The holding jig 3 includes a pressing force adjusting mechanism 4, a holding portion adjusting mechanism 5, and a holding jig fixing mechanism 6. . Reference numeral 7 denotes a flat plate, and the three mechanisms 4, 5, and 6 are integrated by the flat plate 7 to maintain the mutual positional relationship to form the holding jig 3, and the holding jig 3 It is fixed by a holding jig fixing mechanism 6. An adjusting groove 8a is provided on the side of the flat plate 7 where the flat plate 7 and the above three mechanisms intersect.
~ 8e are provided therethrough, while three mechanisms 4,5,6
As will be described later, a thread 9 is cut in the side part. A nut 10 is provided on the thread 9. Thus, the screw mechanism is constituted by the screw thread 9 portion and the nut 10 portion. Further, in the holding portion adjusting mechanism 5, a spherical joint is provided so as to surround the screw mechanism. Here, the spherical joint is not shown in FIG. 1, but FIG. 2 is an external perspective view thereof.

The holding jig fixing mechanism 6 includes a jig leg 6a.
And a jig foot 6b attached to the tip thereof, which further has the following configuration.

The jig leg 6a is provided with a thread 9 in a part of the area where the jig leg 6a intersects the flat plate 7, and a nut mechanism provided in this part constitutes a screw mechanism. Further, the flat plate 7 intersecting with the jig leg 6a is provided with adjustment grooves 8a and 8e. In this manner, the fixing of the jig leg 6a to the flat plate 7, and the fixing position and the inclination angle are determined by the structure 1
It can be set appropriately according to the form of the surface.

On the other hand, the following three types of the jig foot 6b are preferable as specific examples.

One form of the jig foot 6b is provided with a vacuum suction pad, and this vacuum suction pad is connected to a vacuum pump 11 via a vacuum tube 6c. Here, the form and the constituent material of the vacuum suction pad can be vacuum-sucked to the surface of the structure 1 regardless of the surface roughness, regardless of whether the surface of the structure 1 to which the pad is fixed is flat or curved. The holding jig 3 is made of an elastic material, such as hard rubber, which can provide a predetermined fixing force so as not to come off and which can be regarded as a practically rigid material. Accordingly, the operation of the vacuum pump 11 causes the jig foot 6 to move.
b can be attached to the structure 1 with the jig leg 6a fixed to the surface of the structure 1 in close contact with the surface of the structure 1.

As another form of the jig foot 6b, a structure 1
When is made of steel, a device provided with a magnetic attraction device using permanent magnetic force or electromagnetic force can be applied. In this case, it is necessary to match the shape of the contact surface between the bottom surface of the jig foot 6b and the surface of the structure 1, and a permanent magnet or an electromagnet having a magnetic field generation capability equal to or more than a predetermined value according to the contactable area. A magnetic attraction tool consisting of

As still another form of the jig foot 6b, the bottom surface of the jig foot 6b is bonded to the surface of the structure 1 using an adhesive. In this case as well, it is necessary to make the shape of the contact surface between the bottom surface of the jig foot 6b and the surface portion of the structure 1 substantially coincide with each other, and the required contact area is determined from the adhesive force of the adhesive. The type of the adhesive to be used is appropriately selected according to the material of the structure 1.

As described above, the holding jig fixing mechanism 6
Can reliably fix the holding jig 3 at a target position on the surface of the structure 1.

The holding part adjusting mechanism 5 includes a holding rod 12
And a screw mechanism (composed of a screw portion and a nut portion) provided at a portion where the flat plate 7 intersects, a spherical joint surrounding the screw mechanism, and a flat plate 7 at a portion where the holding rod 12 intersects the flat plate 7. It is composed of adjusting grooves 8b to 8d.

FIG. 2 shows an example of a spherical joint used here. In the figure, a spherical joint 13 comprises a joint body 14 and a sliding medium 15 into which the joint body 14 fits.
It consists of An outer peripheral portion of the nut 10 is fitted and fixed inside the joint main body 14, and the outer peripheral portion of the joint main body 14 has a spherical surface portion. The moving medium 15 is set in combination. The materials of the two are appropriately selected so that the attachment position of the attachment is fixed by the sliding resistance of the contact surface between the joint body 14 and the sliding medium 15. The sliding medium 15 of the spherical joint 13 moves in a horizontal plane while being guided by the adjusting groove 8f.

With the above mechanism, the holding portion 12a at the lower end of the holding rod 12 is adjusted by using a screw mechanism for adjusting the position in the height direction, and adjusting grooves 8b to 8c for adjusting the position in the horizontal direction.
By using 8d and adjusting the height direction and the horizontal direction using the spherical joint 13, the attached object 2 can be accurately and easily attached to an arbitrary target position on the surface of the structure 1.

The pressing force adjusting mechanism 4 presses the attached object 2 attached to a predetermined position of the structure 1 with an appropriate pressing force as described above.
This is for pressurizing continuously for a long time. The pressing force adjusting mechanism 4 uses a screw mechanism provided at a position where the presser bar 12 intersects the flat plate 7. However, this screw mechanism is the same as the screw mechanism included in the holding portion adjusting mechanism 5,
The force for holding down the patch 2 can be easily adjusted.

In the above-described embodiment, the screw mechanism that is the pressing force adjusting mechanism 4 is assumed to be common to the screw mechanism that is a part of the configuration of the holding portion adjusting mechanism 5. They may be separately provided separately.

FIG. 3 is a schematic perspective view for explaining another example of the embodiment of the jig for holding the adhered object according to the present invention. In the figure, reference numeral 1 denotes a structure, and 1a denotes a hemisphere constituting a part thereof. As shown in FIG.
Holding jig 3 according to the form of
It is necessary to change various forms appropriately.
That is, the pressing force adjusting mechanism 4, the holding portion adjusting mechanism 5,
The desired object is achieved by appropriately determining the number, size, and mutual positional relationship of the holding jig fixing mechanism 6 and the holding jig. As can be seen from this, the holding jig of the present invention is not limited to those illustrated in FIGS. 1 and 3.
