Sample holder for receiving a sample
A sample holder for receiving a sample includes a sample receiving device for clamping the sample, which is assigned a holding means which has at least two prongs protruding from the sample receiving device for a gripping means. Also disclosed are a receiving device, a sample holder magazine, a sample feeding system, a clamping device and an examining device.
1. A test unit comprising:
at least one specimen holder for mounting a specimen, the specimen holder including a specimen mounting device for clamping the specimen, a holding means being assigned to said specimen mounting device, said holding means having at least two pegs, which protrude from the specimen mounting device; and
a specimen feed system for feeding specimen holders to the test unit, wherein the specimen feed system comprises a gripping system which grips the specimen holder on the holding means and feeds the specimen holder to the test unit.
2. The test unit as claimed in claim 1 , wherein the pegs have an approximately conically shaped end region.
3. The test unit as claimed in claim 1 , wherein the pegs of the specimen holder protrude perpendicularly from opposite sides of the specimen mounting device.
4. The test unit as claimed in claim 1 , further comprising a mounting device, for mounting the holding means of the specimen holder.
5. The test unit as claimed in claim 4 , wherein the mounting device has a first mounting angle and a second mounting angle, each mounting angle having an approximately L-shaped cross section with a first leg and a second leg.
6. The test unit as claimed in claim 5 , wherein a recess is formed into each of the first legs of the mounting angles.
7. The test unit as claimed in claim 6 , wherein the recesses are surrounded by a first depression.
8. The test unit as claimed in claim 7 , wherein the first mounting angle has a second depression which is formed into the first depression.
9. The test unit as claimed in claim 4 , 1 wherein the specimen feed system includes a specimen holder magazine having a carrier stand to which the mounting device for the specimen holder is fastenable.
10. The test unit as claimed in claim 1 , wherein the gripping system has two gripping pliers at a distance from one another which grip the holding means of the specimen holder.
11. The test unit as claimed in claim 1 , wherein the gripping system is pivotable about its longitudinal axis.
12. A specimen holder for the test unit as claimed in claim 1 .
13. The test unit as claimed in claim 1 , wherein the at least one specimen holder comprises a plurality of specimen holders including at least two types of specimen holders chosen from a specimen holder for a compression test, a specimen holder for a tensile test, a specimen holder for a shear test, or a specimen holder for a bending test.
