  However, in the polishing jig of Patent Document 1, since the plate-like sample 103 is attached to the lower surface 101a of the sample fixing block 101 using an adhesive such as wax, the plate-like sample is reliably and stably attached. It is difficult to say that the sample can be fixed, and it is difficult to say that the sample can be fixed without affecting the sample (in other words, the state of the sample is maintained as it is). Specifically, in the case of dry polishing, 1) the heat generation during polishing deteriorates the performance of the adhesive and the sample comes off, and 2) the adhesive adheres to the surface due to the heat softening property of the adhesive. There is a problem that the sample surface is contaminated, and in the case of wet polishing, 1) the adhesion of the adhesive is reduced and the sample comes off, and 2) the adhesive is wiped off with a solvent after polishing. At this time, there is a problem that the sample surface is contaminated by the adhesive slightly remaining on the surface.

  Further, since the plate-like sample 103 is attached to the lower surface 101a of the sample fixing block 101 using an adhesive such as wax, it is necessary to completely remove the adhesive after the polishing of the plate-like sample 103. There is a problem that this removal process has an effect of changing the state of the plate-like sample 103, and there is a problem that it is necessary to remove the adhesive completely.

  Therefore, the present invention can easily and surely and stably fix the plate-like sample or the like without affecting the state of the plate-like sample to be polished, and does not require extra effort. An object of the present invention is to provide a plate-shaped sample polishing jig capable of fixing and removing a plate-shaped sample.

Take 7 as an example. The size and thickness of the plate sample that can be fixedly held by the plate sample polishing jig of the present invention are not limited to a specific one. Specifically, for example, the thickness may be thinner than 2 [mm] or thicker if the sample itself does not buckle. However, when a sample having a thickness of about 2 [mm] is fixed and held, the effect of the present invention that can be reliably fixed as compared with the conventional jig is particularly remarkable. In other words, the present invention is particularly suitable for fixing a plate-like sample having a thickness of about 2 [mm].

  The material of the first member 2 and the second member 3 is specified as long as it has sufficient strength to clamp and fix the plate-like sample 7 between the pressing portion 2b and the pressing receiving portion 3b. It is not limited to the material. Specifically, for example, brass is used. However, when the plate-like sample 7 is polished using, for example, a chemical, it is desirable to use a material that does not corrode by the chemical.

  Each of the first member 2 and the second member 3 is a portion corresponding to most of each, and a portion corresponding to the base is formed in a rectangular parallelepiped shape, and is arranged with one surface of the six rectangular parallelepipeds facing each other. Is done.

A portion 4b on the distal end side of the pressing screw 4 protrudes from the opening on the member facing surface 6A side.

  The pressing screw 4 has a male screw formed at least on a tip end portion 4b protruding from the first member facing surface 6A. Note that no screw thread is formed on the inner peripheral surface of the screw through-hole 2c, and the screw through-hole 2c supports the pressing screw 4 by allowing it to slide and rotate freely.

  The guide pin fixing hole 2d is formed as an axial hole having an opening in the first member facing surface 6A. The guide pin fixing hole 2d of this embodiment is not a through hole, but the guide pin fixing hole 2d may be formed as a through hole. The two guide pin fixing holes 2d and 2d are opposed to each other with the screw through hole 2c interposed therebetween, and the straight line connecting the axis of each of the screw through hole 2c and the guide pin fixing holes 2d and 2d is parallel to the plate surface of the pressing portion 2b. It is formed to become.

  One end side of the rod-shaped guide pins 5 and 5 is inserted into each of the guide pin fixing holes 2d and 2d and fixed by an adhesive or the like. The other end of the guide pin 5 protrudes from the first member facing surface 6A. Moreover, in this embodiment, the guide pin 5 is formed with steel.

  The pressing portion 2b is perpendicular to the first member facing surface 6A, which is one of the six surfaces of the base portion 2a, and the pressing screw 4 in the axial direction with respect to the first member facing surface 6A The guide pins 5 and 5 are formed in a thin plate shape protruding in the protruding direction. That is, the pressing screw 4, the guide pins 5 and 5, and the pressing portion 2b protrude from the first member facing surface 6A in the same axial direction.

  On the other hand, the second member 3 is formed with a screw hole 3c into which the pressing screw 4 is fitted, and guide pin insertion holes 3d and 3d into which the two guide pins 5 and 5 are inserted, respectively. In the present embodiment, the screw hole 3c and the guide pin insertion holes 3d and 3d are formed as through holes, but may be formed as holes that do not penetrate.

  The screw hole 3c is formed as a through hole in the axial direction at the axial center position, and a female screw into which the pressing screw 4 is screwed is formed on the inner peripheral surface.

  The guide pin insertion holes 3d and 3d are formed on the two guide pins 5 and 5 protruding from the first member facing surface 6A when the first member facing surface 6A and the second member facing surface 6B face each other. The guide pins 5 and 5 are slidably inserted into the shaft holes at positions.

  The first member 2 and the second member 3 slide on the screw through hole 2c of the first member 2 with the first member facing surface 6A and the second member facing surface 6B facing each other. A distal end side portion 4b of the pressing screw 4 penetrating freely and pivotably protruding from the first member facing surface 6A is screwed into the screw hole 3c of the second member 3, and the first member facing surface 6A. The two guide pins 5 and 5 protruding from the second member 3 are combined in a state of being inserted into the guide pin insertion holes 3d and 3d of the second member 3, respectively.

  At this time, the pressing portion 2b of the first member 2 can slide the surface on the base 2a side of the front and back plate surfaces on one surface of the second member 3 (hereinafter referred to as a mounting surface; reference numeral 3a). Put it in contact with.

  The second member 3 is placed on the side of the mounting surface 3a on which the pressing portion 2b comes into contact and opposite to the side on which the pressing portion 2b comes in contact (in other words, the protruding portion 2b protrudes). There is provided a pressing and receiving portion 3b formed as a belt-like convex portion (so that a belt-like concave portion is formed between and facing the tip portion).

  Then, by tightening the pressing screw 4, the first member 2 and the second member 3 come close to each other between the pressing portion 2 b of the first member 2 and the pressing receiving portion 3 b of the second member 3. The width in the axial direction of the band-shaped recess (hereinafter referred to as the sample clamping portion) 3e changes, and the plate-like recess placed on the sample clamping portion 3e with one surface in contact with the placement surface 3a The sample 7 is clamped and fixed by holding the pressing force in the axial direction between the pressing portion 2b and the pressing receiving portion 3b. As a result, the plate-like sample 7 is sandwiched and fixed between the pressing portion 2b and the pressing-receiving portion 3b while being in contact with the mounting surface 3a, so that the plate-like sample polishing treatment is very stable. Fixed to the tool 1.
