[0027] The indentation tester 100 according to the first embodiment is a rod-type instrumented indentation tester capable of continuously monitoring the test force (load) applied to the indenter 4 and the indentation depth of the indenter 4 .

[0028] like Figure 1-5 As shown, the indentation tester 100 includes a tester body 1 that applies a test force to a sample S; a controller 200 that controls various components of the tester body 1 ; a display 300 ; and an operator 400 .

[0029] The tester main body 1 includes, for example: a base 2 on which a sample S is placed; a load rod 3; an indenter column 41; a displacement sensor moving part 5a (indenter coupling head); load applicator); reference rod 7 (pressure bracket); contactor 8 (indenter reference part); adjustment device (regulator) 9; displacement sensor fixing portion 5b (indenter position detector); second actuator motor 10 ( indenter reference portion driver); the brake 12 ; and the controller 200 that controls the...

[0055] The difference between the second embodiment and the first embodiment is that the second embodiment provides the indentation tester 110 of the present invention, which is a directly instrumented indentation tester, and is different from the indentation tester 100 in that it is a rod Type instrumented indentation tester. In particular, the indentation tester 110 of the second embodiment is a direct instrumented indentation tester capable of continuously monitoring the test force (load) applied to the indenter 4 and the indentation depth of the indenter 4 . Also, in order to simplify the description, the same reference numerals are used for the structures similar to those of the first embodiment, and the detailed description thereof is omitted.

[0056] like Image 6 and 7 As shown, the indentation tester 110 includes, for example: the sample stage 21 on which the sample S is placed; the indenter column 41; the displacement sensor moving part 5a (indenter coupling head)...

[0068] Figure 8 The example shown differs from the first embodiment, for example, in the shape of the indenter 4A, the shape of the contactor 8A, and the fixed position of the adjustment device 9 . In particular, the indenter 4A has a seating surface 43A on which the adjustment device 9A can be placed, the seat surface 43 being formed in the vicinity of the circumferential outer surface of a portion of the indenter 4A in contact with the bottom surface of the indenter post 41A. The indenter 4A is thus able to place the adjustment device 9A clamped on the seat surface 43A. In Alternative Example 1, the second hollow disk 91B is placed on the seating surface 43A of the indenter 4A and the top surface of the first hollow disk 91A contacts the bottom surface of the indenter column 41A. In particular, alternative example 1 enables the indenter 4A to hold the adjustment device 9A instead of the contactor 8A.

[0069] As described above, the adjustment device 9A is configured such...

Abstract

The invention disclsoes an indentation tester. Indentation tester capable of adjusting vertical-direction positioning drift due to individual differences of an indenter when indenters are switched includes an adjustment mechanism. The adjustment mechanism adjusts relative vertical-direction positions of a displacement sensor movable portion and a displacement sensor fixed portion. The adjustment mechanism includes a first hollow disk having a spiraling surface formed on a bottom surface; and a second hollow disk having a spiraling surface 91 formed on a top surface. The spiraling surfac of the second hollow disk has a thread equal to that of the spiraling surface 91 of the first hollow disk. The first hollow disk rests on the second hollow disk such that the bottom surface of the first hollow disk is overlaid on the top surface of the second hollow disk. The first hollow disk and the second hollow disk are capable of rotation on a center axis of an indenter column.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims priority to Japanese Application No. 2012-123893, filed on May 31, 2012, under 35 U.S.C. § 119 (35 U.S.C. §119), the contents of which are hereby incorporated by reference in their entirety. invention. technical field [0003] The present invention relates to an indentation tester. Background technique [0004] Generally, in a known material testing apparatus, an indentation tester forms an indentation by pressing an indenter column into the surface of the sample, the indenter column having an indenter at its foremost end. The indentation tester then measures the indentation depth (the amount of displacement of the indenter) by means of a displacement gauge. Based on the relationship between the displacement and the load placed on the indenter, the indentation tester measures the value of a physical parameter of the specimen, such as hardness. (See, eg, Japanese Patent Laid-Open No. 2009-15668...
