Portable Brinell hardness tester

Abstract

The invention portable type brinell tester, the characteristic is that it includes pressure head strut, cut forelock and pressure head; setting the pressure head hole on the axes place of the bottom of pressure head strut, setting the cut forelock hole on the vertical cross place of the axes place of the bottom of pressure head strut; pressure head hole and cut forelock hole interpenetrate each other; setting the cut forelock in the cut forelock hole, setting the pressure head in the pressure head hole, superior extremity face touches with the middle of cut forelock, the bottom of pressure head comes out from pressure head hole. When doing the rigidity detection, throwing the pressure on the top of pressure head strut by the augmentor of dynamic or static state, when the test force reach cut forelock scissor broken, the cut forelock is cut three parts by pressure head strut and the top brink of pressure head. The advantage is easy operation, convenient carry,not need sample, it can test large scale work piece unable centre gripping on site testing and removing discommodityly.

Description

Technical field: [0001] The invention relates to a device for testing the hardness of metal materials, in particular to a portable Brinell hardness tester. Background technique: [0002] Ordinary desktop hardness testers are usually used to test the hardness of metal materials, which are large in size and weight, and are placed on the workbench and cannot be moved. The application and removal of the test force of the bench-top hardness tester is completed through a complex lever system to control the lifting of the standard weight weight, thereby generating different test forces to act on the indenter. For hardness testing, the specimen must be placed between the indenter and the anvil. Benchtop hardness testers have several disadvantages and deficiencies, including: [0003] 1. On-site testing is not possible, and workpieces that have been installed or are not easy to move cannot be tested; [0004] 2. It is not possible to test large workpieces whose size exceeds the op...
