Problems solved by technology

In the lifting screw mechanism, the mechanical force used will cause the accuracy of displacement measurement to decrease, resulting in errors in measurement results, and other possible deviation losses will also cause displacement measurement errors
[0014] All known hardness measuring instruments are not suitable for measuring hole-shaped and groove-shaped samples

Embodiment approach

[0055] now refer to figure 1 The inventive meter is described. like figure 1 As shown, the measuring instrument of the present invention includes a set of components, which includes a base 1 and a box-shaped frame 2 . The box-shaped frame 2 is fixed on the base 1, and the base 1 is the structural basis of the measuring instrument. The movement of the sliding device 3 is accomplished by controlling an AC servo motor 9 installed at the bottom of the box frame 2 . The AC servo motor 9 drives the threaded ball screw 6 . A pair of sliding shafts 4 straddles both sides of the ball screw 6 . The slide 3 is fitted with linear motion ball bearings or sliding elements 5 which allow the slide 3 to move vertically along the slide axis 4 . The slide device 3 is driven by a ball screw 6 .

[0056] The AC servo motor 9 is tightly connected with the ball screw 6 through a coupling 16 . The ball screw 6 is mounted on the box frame 2 through bearings 14 and 15 .

[0057] The ball nut 7 ...

Abstract

A testing machine includes a stand and a test device. The stand includes a base, box frame, a slide device driven to slide by a motor, and a control system controls the force applied on the test specimen. The test device is coupled at the slide device for performing various hardness tests consisting of Rockwell hardness test, Vickers hardness test, Brinell hardness test, micro-hardness test, and tension-compression test. The test device includes a force sensor and a data processing circuit converting an analog signal of the force sensor into digital data to interface with the control system.

Description

[0001] References related to this application [0002] This application is a formal application claiming priority under the conditions of 35 U.S.C.§119 for the provisional application No. 61 / 283,902 with a filing date of 12 / 09 / 2009. technical field [0003] The present invention relates to a material hardness and tension compression testing device, in particular to an indentation hardness tester, which allows users to use various types of hardness tests to detect and obtain highly accurate material hardness. Background technique [0004] Those skilled in the art know that the laboratory needs many types of material measuring instruments, such as Rockwell hardness measuring instrument, Brinell hardness measuring instrument, Webster hardness measuring instrument, microhardness measuring instrument and Knoop hardness measuring instrument, in addition Tensile compression measuring instrument. All manufacturers want to manufacture an instrument that can perform the same function...
