DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a replica collecting apparatus used for collecting the surface shape of the inner wall surface of a long hole or a groove or for collecting a metal structure.

[0002]

2. Description of the Related Art Conventionally, as one of means for collecting the surface shape of an inner wall surface of a long hole or a groove, there is a method of collecting a replica using a molding material. In this method, the molding material is directly pressed evenly on the inner surface to be inspected such as a long hole so as to conform to the surface shape of the surface to be inspected. This is to peel off and collect a replica of the surface to be inspected.

[0003]

However, according to the above-mentioned conventional method of collecting a replica, the molding material must be uniformly pressed against the surface to be inspected, and the collected molding material must be peeled off so as not to be damaged. There was a problem that a precise replica could not be collected. In this operation, since the molding material must be pressed uniformly and peeled off accurately, a skilled inspector has to rely on a conventional inspector.
Furthermore, it is very difficult to obtain a precise replica when the surface to be inspected is deep, such as when sampling the surface shape of the inner bottom wall such as a long hole, and it is very difficult to use a jig such as a long pipe. He was working with the intuition of the inspector.

Accordingly, the present invention solves such disadvantages found in the conventional replica sampling method, and can uniformly press the molding material against the surface to be inspected without special skills. An object of the present invention is to provide a replica collecting apparatus that can accurately and easily perform peeling after curing. In addition, even the surface to be inspected at the bottom such as a long hole or a groove can be operated from outside the hole, and not only a replica of the surface shape of the surface to be inspected but also the metal structure of the surface to be inspected is collected. It is an object of the present invention to provide a replica collecting device capable of performing the above.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems in the replica sampling apparatus, the present invention provides a pressing member attached to the front surface of the lower end of a guide frame for pressing a molding material against a surface to be inspected. And a slider mechanism mounted on the back surface of the lower end of the guide frame and slidable up and down by an operation member, and a parallel link mechanism that extends in conjunction with the sliding of the slider.

In addition, the replica collecting apparatus is provided with a jet nozzle capable of spraying a transfer solution onto the surface to be inspected, and the transfer film is pressed against the surface to be inspected by using a replica which has been collected in advance, thereby obtaining a metal structure. Adopt a structure that enables

[0007]

According to the replica collecting apparatus of the present invention, the molding material is held by the pressing member on the front surface of the lower end of the guide frame and inserted into the position opposite to the surface to be inspected. Next, by depressing the operation member, the slide mechanism on the rear surface of the lower end portion of the guide frame is lowered, and the parallel link mechanism is extended in conjunction with the mechanism. By extending the parallel link mechanism, the rear wall, such as a long hole, is pressed, and by this reaction, the guide frame is pushed vertically forward from the back, covering the center of the pressing member attached to the front of the guide frame. Press perpendicular to the inspection surface. Accordingly, the molding material is uniformly pressed while being sandwiched between the pressing member surface and the surface to be inspected.

Further, in this state, after the molding material is hardened, the operating member is pulled up to release the extension of the parallel link mechanism, and then the guide frame is slightly rotated to move the molding material from the surface to be inspected. Can be easily peeled off.

Next, when a metal structure is to be sampled, the surface of the replica sampling section is covered with a transfer film using the molding material obtained by the above operation, and the apparatus is inserted and set on the surface to be inspected again. Then, the position is adjusted so that the transfer film contacts the surface to be inspected, and the parallel link mechanism is temporarily released. Next, the transfer solution is injected from the upper part of the jet nozzle, sprayed from the nozzle tip to the surface to be inspected, etched, and then the operating member is pushed down to expand the parallel link mechanism and press the pressing member against the surface to be inspected. When the contact portion between the transfer film and the surface to be inspected is dissolved by the solution, flows into the metal details, and waits until it is dried, the detailed structure is transferred to the film. The subsequent operation is the same as the above-mentioned surface shape replica collection, and the collection operation is completed by peeling the transfer film from the surface to be inspected without difficulty.

[First Embodiment] In FIG. 1, reference numeral 1 denotes a guide frame having a length sufficient to reach a surface B to be inspected such as a long hole A; Positioning rods for adjusting the length of the insertion part by inserting it into the hole 3 and 4 are installed at the entrance of a long hole, etc.
Hollow donut-shaped support flanges for supporting the positioning rod 2, 5 and 6 are members constituting a pressing member, and 5 is attached to the front surface of the lower end portion of the guide frame 1 and presses the molding material against the surface to be inspected. Pad plate with surface, 6
(6a and 6b) are L-shaped plates for holding the molding material 7 on the back surface of the pad plate 5, and 7 is a molding material (rubber-based material) which is directly pressed to the surface shape of the surface to be inspected and collected as a replica. It is.

Reference numeral 8 denotes an operating member, 9 denotes a bearing block for supporting the operating member 8, 10 to 11 are slide mechanisms,
Reference numeral 0 denotes a slide rail mounted on the rear surface of the lower end of the guide frame 1, and reference numeral 11 denotes a slider that can slide on the slide rail 10 by the operation member 8. Numerals 12 to 13 are members constituting a parallel link mechanism, and 12 is a sliding slider 11.
The parallel link that expands and contracts in conjunction with

[Operation of the First Embodiment] According to the replica sampling apparatus of the first embodiment having the above-described configuration, first, the molding material 7 is pressed against the front surface of the pad plate 5 at the lower front portion of the guide frame 1. The ends are extended so as to be wound around the pad plate 5, and the L-shaped plates 6a and 6b are fixed so that the wound part of the molding material 7 is sandwiched from the back. Next, the support flange 4 is set at the entrance of the elongated hole A where a replica is to be collected, and the positioning rod 2 is inserted into the step hole 3 according to the depth of the surface to be inspected to adjust the length of the insertion portion. Then, the leading end of the guide frame 1 is inserted into the elongated hole A through the opening of the support flange 4. When the positioning rod 2 is mounted on the upper surface of the support flange 4, the guide frame 1 is suspended, and the orientation of the guide frame 1 is adjusted so that the molding material 7 faces the surface B to be inspected in this state.

Next, the upper end of the operating member 8 is pushed down.
As a result, the slider 11 connected to the lower end of the operating member 8 slides on the slide rail 10 and is pushed down, and the parallel link 12 having one end attached to the slider 11 is moved in conjunction therewith. The kick plate 13 attached to the other end is vertically pressed against the rear wall of the elongated hole A or the like.

A jet nozzle 14 which can inject the solution onto the surface B to be inspected, which is the tip of the pipe 15, is added to the first embodiment.

[Operation of the Second Embodiment] When a metallographic replica of the surface B to be inspected is sampled, the molding material 7 (already hardened replica) obtained by the operation of the first embodiment is used. The surface of the replica collecting section is covered with a transfer film (cellulose-based film sheet), and the apparatus is inserted into the long hole A again so that the transfer film faces the surface B to be inspected. Next, the transfer solution is injected from above the solution injection pipe 15 and sprayed from the tip of the jet nozzle 14 onto the surface B to be inspected to etch the surface, and then the operating member 8 is pushed down to extend the parallel link mechanism. When the pad plate 5 is pressed against the surface to be inspected, the contact portion of the transfer film with the surface to be inspected is melted out by the solution, flows into metal details, and waits until it is dried. Thereafter, by the same operation as the surface shape replica collection, the transfer film is easily peeled off from the surface to be inspected, thereby completing the collection operation.

Note that the operating member 8 is shown in FIGS.
In addition to the rod-shaped ones shown in FIG. 1, a combination of a chain and a sprocket, a screw-type one consisting of a male screw and a female screw, a cylinder-type one, a motor-driven one or the like may be used.
