为了便于使用洛氏硬度计测试凸轮轴凸轮表面硬化层硬度,提高测试精度,我们制作了一种平衡器,经使用证明能提高测试精度和工作效率。现作一简单介绍: 平衡器(如图所示)由连接双头螺栓1,平衡调节螺母2,主杆3和挂钩4组成。连接双头螺栓1可按工件螺孔大小更换。使用时,将连接双头螺栓1拧紧在工件右 In order to facilitate the use of Rockwell hardness test camshaft surface hardness of the hardened layer to improve test accuracy, we have produced a balancer, the use of proven to improve test accuracy and work efficiency. Now make a brief introduction: Balancer (as shown) from the connection stud 1, balance adjustment nut 2, the main rod 3 and the hook 4 components. Connecting studs 1 can be replaced by the size of the workpiece screw hole. In use, tighten the connecting studs 1 to the right of the workpiece
