Further optimally, the elastic pressing sheet is fixed on the clamp, and the screw hole is formed in the clamp.

Preferably, the cross section of the clamp groove is semicircular, and the diameter of the clamp groove is 16 mm.

Further optimally, the outer edge of the semicircular pin is 16mm in diameter and 18mm in height.

Preferably, the width of the test block groove is 12.4mm, and the depth is 2 mm.

Further optimally, the test block is a cuboid of 12.32mm × 12.32mm × 19.05 mm.

The utility model has the advantages that:

the utility model has the advantages of simple and reasonable structure, at first put into the anchor clamps inslot of anchor clamps with the semicircle round pin, put into the test block inslot on the semicircle round pin again, then through the fixed test block of clamp bolt and elastic compression piece, the test machine is to applying load between test ring and test block, loosens clamp bolt, and the test block is in free state this moment, controls the rotatory test ring of test machine again, and test ring and test block can automatic alignment, after experimental, stop rotatory test ring, take out the test block. The changed clamp enables the width of the grinding trace of the test block to be uniform, the precision of the testing machine on the part processing requirement is reduced, the testing machine is convenient to process and assemble, the production cost of the testing machine is reduced, and the operation is convenient.

Detailed Description

In order to clearly illustrate the technical features of the present invention, the present invention is explained in detail by the following embodiments in combination with the accompanying drawings. In the description of the present invention, it should be noted that the terms "left", "right", "front", "back", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

As shown in fig. 1-5, the utility model provides a test block automatic alignment mechanism of ring block abrasion testing machine, including anchor clamps 1, semicircle round pin 6 and test block 7, anchor clamps are stool type anchor clamps (as shown in fig. 1, 2), and fixed orifices 2 has been seted up to anchor clamps 1's top, has seted up the fixed orifices and is convenient for fix anchor clamps on the testing machine. The clamp groove 5 is formed below the clamp 1, the elastic pressing piece 3 is fixed on the right side of the clamp groove 5, and the elastic pressing piece is fixed on the clamp 1.
