A Rockwell hardness tester with the function of adjusting the angle of the measuring platform

Abstract

The invention relates to a Rockwell hardness tester with the function of adjusting the angle, which comprises a body, an indenter installed on the body, a lifting column vertically arranged on the body and directly below the indenter, and a lifting column arranged on the lifting column for The measuring platform where the test block is placed, the middle position of the lower surface of the measuring platform is provided with a connecting piece hinged with the lifting column, and there is an adjustment gap between the measuring platform and the lifting column; Clamping device; the lower surface of the measurement platform and the positions on both sides of the connector are respectively hinged with sleeves, the sleeves are vertically arranged, and the lifting column is provided with a drive that can drive the sleeve to move up and down to adjust the angle of the measurement platform components. The invention has the advantage that the angle of the measurement platform can be adjusted according to the measurement requirements, so as to adapt to different types of blocks to be tested.

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 ...

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 is a certain angle between the measured surface of the block and the indenter. If an external force is applied to measure at this time, the hardness measurement data will be distorted, and the indenter may be damaged or broken, and even the lever mechanism inside the equipment will be bent and deformed.
