The invention discloses a digital display type mold hardness measuring device. The measuring device includes a measuring tube, which is vertically arranged on the side of the main machine and connected with the main machine. The main machine is provided with a digital display screen, and the main machine is provided with a hardness sensor. The first A / D conversion circuit is connected to the digital display screen. The measuring tube is equipped with an energy storage spring. There is a measuring probe, the measuring probe passes through the measuring tube in the free state of the energy storage spring, the host is equipped with a guide groove coaxial with the energy storage spring, the hardness sensor is fixed in the guide groove, and the measuring probe is offset against the groove / hole to be measured Drive the energy storage spring to squeeze the hardness sensor upwards. The invention is simple in structure and easy to use, not only satisfies the determination of the hardness and strength of the deep groove / hole of the mold, but also improves the measurement accuracy and efficiency.
Description
technical field [0001] The invention relates to the technical field of hardness test equipment, in particular to a digital display mold hardness measurement device. Background technique [0002] A hardness tester is a testing device used to measure the hardness of a material. Hardness testers are divided into two types: desktop hardness testers and portable hardness testers. The desktop hardness testers are mainly used in laboratories and have the advantages of high precision. The portable hardness testers are used for installed Brinell or permanent assembly parts and are easy to carry. Mainly divided into portable Leeb hardness tester, portable Rockwell hardness tester, portable Brinell hardness tester. [0003] In the actual measurement process, such as when inspecting the mold, if there are grooves or holes on the surface of the mold, due to the heat generated during the drilling or milling process, thermal stress changes will occur in the hole or the groove, so The har...
