昇させ、押えねじで圧子を固定する。[Prior Art] An ultraviolet ray technology that is equipped with a microscope for observing a test surface and an indenter to which a predetermined load is applied, and measures the hardness of a test piece by pressing the indenter into the test piece and measuring the indentation formed. There is a microhardness meter. Conventionally, when replacing the indenter in such an ultra-micro hardness tester, it was done as follows. First, the microscope is focused on the surface of a plate-shaped jig made of a very hard material with a H v = 700 that is placed on a sample stage. At that height, loosen the indenter's retaining screw and bring the tip of the indenter into contact with the jig surface. Raise the document table by an amount that is thought to be approximately 10 μm using the lift handle, and secure the indenter with the retaining screw.

らなかつた。[Problems to be solved by the invention] However, the lifting handle mentioned above has some play, and it is very difficult to adjust the small amount of 10 μm. There was a problem in that it was extremely difficult to fix the indenter at a desired position because the degree of penetration into the jig surface differed each time. Even if the indenter digs into the jig surface even slightly (approximately 5 μm), the displacement measurement range of the ultra-fine material testing machine may be exceeded, so the monotonous and delicate work must be repeated over and over again until it is installed at the correct height. I had to.

is used to represent the procedure for replacing the indenter. First, the indenter exchange jig 1 is fixed on the XY table 3 on the sample stage 4, and the microscope is focused on the reference plane 15. Thereafter, the portion of the support surface 16 on which the diamond is attached is moved into the field of view of the objective lens 2. At this time, the focus will be slightly blurred, but there is no problem as long as you measure the distance you need to move in advance. Then, the sample stage 4 is rotated around the rotating shaft 5, the jig is moved below the indenter 6, and the presser screw 7 of the indenter 6 is moved.
Loosen the indenter and bring the tip of the indenter into contact with the diamond surface of the jig. Tighten the cap screw at this position to secure the indenter.

This indenter exchange jig 1' consists of two members 10 and 11. A reference surface 15 is formed on the upper surface of the member 10. The member 11 has a thickness t, and diamonds 8 are fitted in predetermined positions. The indenter is replaced as follows. on sample stage 4
Fix the member 10 on the XY table 3,
The objective lens 2 of the microscope is focused on the reference plane 15 of the microscope. The sample stage is rotated by the rotating shaft 5, and the member 11 is placed on the member 10. At this time, member 1
A support surface 16 is formed on the support surface 1 . Loosen the cap screw 7 of the indenter 6 and bring the tip of the indenter into contact with the diamond 8 on the support surface 16. At this position, tighten the cap screw 7 to fix the indenter 6.

る。 When the tip of the indenter 6 is brought into contact with the diamond 8 in this way, the tip of the indenter 6 will not bite into the support surface 16 because the diamond is very hard.
The indenter 6 is fixed at the supported position.
なお、超微小材料試験機がマイクロビツカース
硬度計である場合は、上記ｔの値は0.6mm程度と
すればよい。 Note that when the ultra-fine material testing machine is a micro-Vickers hardness meter, the value of t may be about 0.6 mm.

は殆んどなく、圧子を正しく位置決めできる。 The indenter exchange jig of the ultra-fine material testing machine according to this invention forms the reference surface and the support surface of the step t, so when the indenter tip is brought into contact with the support surface, the indenter tip automatically changes. It comes to a position t above the sample piece. In addition, a diamond is attached to the support surface where the indenter tip contacts, so the indenter does not touch the support surface when the indenter tip contacts the support surface or when the indenter is fixed by tightening the screw. There is almost no digging, and the indenter can be positioned correctly.
Hv＝700程度の治具を用いる従来の方法では、
圧子の交換に熟練者でも１〜２時間が必要であ

つたが、本考案の治具を用いれば顧客側でも交換
が可能となる。 In the conventional method using a jig with H v = about 700,
It takes one to two hours even for an experienced person to replace the indenter, and it was difficult for a service person to replace it at the customer's site, but by using the jig of the present invention, it becomes possible to replace the indenter at the customer's site as well.
