Embodiment Construction

[0018] The present invention is further described in conjunction with accompanying drawing and specific embodiment:

[0019] The main content of the present invention is to design a set of Shore hardness test force verification system, wherein the test force loading device can realize slow and steady loading of the test force, and keep the indication values ​​of the Shore hardness tester and the standard force measuring instrument stable at the verification point.

[0020] The present invention mainly designs a test force verification device for a Shore hardness tester. The device is composed of a special calibration stand, a force sensor, and a high-precision digital force tester.

[0021] The calibration stand is mainly composed of a base and a screw nut transmission mechanism. Among them, a special clamp with a spring structure is designed on the nut mechanism, which can realize the fixing of Shore hardness testers of different sizes.

[0022] During verification, fix the i...

Abstract

The invention relates to the field of durometer calibration, in particular to a shore durometer test force calibration device, which comprises: a special calibration rack, wherein the special calibration rack comprises a base and a lead screw nut transmission mechanism, the nut transmission mechanism is composed of a handle, a lead screw, a nut and a clamp, the clamp is arranged on the lead screwthrough the nut, and the handle drives the lead screw to enable a to-be-measured piece to move downwards to contact with a force measuring sensor; the force measuring sensor which is arranged on the base and is placed under a shore durometer to be measured; and a high-precision digital dynamometer which is connected with the force measuring sensor through a cable and is used for reading a numerical value. According to the invention, the shore durometer is fixed on the clamp, and the handle is shaken to drive the lead screw to rotate so as to enable the test force to be slowly and stably applied to the shore durometer, so that the impact phenomenon in the stress application process can be avoided, and the shore durometer can be kept fixed when the test force is applied to a rated force value.

Description

technical field [0001] The invention relates to the field of hardness tester verification, in particular to a test force verification device for a Shore hardness tester, which can meet the needs of measurement departments and related enterprises and institutions for accurate verification of the Shore hardness tester. Background technique [0002] The ability of a material to locally resist pressing a hard object into its surface is called hardness. Hardness is an important performance index to measure the softness and hardness of materials. It can be understood as the ability of materials to resist elastic deformation, plastic deformation or damage, and it can also be expressed as the ability of materials to resist residual deformation and anti-damage. Hardness is not a simple physical concept, but a comprehensive index of mechanical properties such as elasticity, plasticity, strength and toughness of materials. Hardness test can be divided into static pressure method (such...
