Problems solved by technology

[0005] However, the above prior art has the following disadvantages: it is only applicable to the block to be tested whose surface to be tested is perpendicular to the axis of the indenter. When the surface to be tested has a certain slope (such as a right triangle or a right trapezoid, etc.), There i

Abstract

The invention relates to a Rockwell hardness tester with the function of adjusting the angle of a measuring platform. The Rockwell hardness tester comprises a tester body, a pressing head installed onthe tester body, a lifting column vertically arranged on the tester body and located under the pressing head and the measuring platform arranged on the lifting column for placing a to-be-tested block; a connecting piece hinged to the lifting column is arranged in the middle of the lower surface of the measuring platform, and an adjusting gap exists between the measuring platform and the lifting column; the upper surface of the measuring platform is provided with a clamping device for fixing the to-be-tested block; vertical sleeves are hinged to the portions, located at the two sides of the connecting piece, of the lower surface of the measuring platform, and the lifting column is provided with a driving assembly capable of driving the sleeves to move up and down to adjust the angle of themeasuring platform. The Rockwell hardness tester has the advantages that the angle of the measuring platform can be adjusted according to measuring demands to adapt to different types of to-be-testedblocks.

Description

technical field [0001] The invention relates to the technical field of Rockwell hardness testers, in particular to a Rockwell hardness tester with the function of adjusting the angle of a measuring platform. Background technique [0002] The Rockwell hardness tester is a measuring instrument that determines the hardness value of the block to be tested through the depth of plastic deformation of the indentation on the surface of the block to be tested. [0003] The existing Rockwell hardness tester includes a base, a frame and a cross arm arranged sequentially from bottom to top. The three are integrally connected and form a C shape. The lower surface of the cross arm is provided with an indenter, and the upper surface of the base is equipped with a lift The platform, the lifting platform includes a measuring platform directly below the indenter, and a lifting mechanism that drives the measuring platform up and down. [0004] When measuring, the block to be tested is placed ...
