在补偿器、金属软管和可伸缩的金属膜盒中,作为可弯元件使用的波纹壳体的强度和可靠性,由波纹轮廓的参数及制造质量决定。在生产中力图得到公差小的壳体,为了断定符合设计文件,就从制造的每批壳体中挑选一个制成宏观轮廓试片,在显微镜上测量它的参数:节距t、高度h、顶部半径R1和凹槽半径R。但是,这种方法生产效率低,并且不可能客观地测定一批当中每个壳体的轮廓参数。为了无损检测任何波纹壳体的参数特研制成万能量具。左图表示测量波纹高度h的工具。它是用螺钉2固定有套3的测微螺钉1。在活动杆4上安装滑块5,在滑块5上压装直径0.6～0.7mm的针6。可换套7,保证
The strength and reliability of corrugated housings used as bendable elements in compensators, metal hoses and telescoping metal bellows are determined by the parameters and quality of the corrugated profile. In order to determine the conformity to the design document, a shell was selected from the manufactured batches to produce a macro-contour test strip and its parameters were measured on a microscope: pitch t, height h, Top radius R1 and groove radius R. However, this method is inefficient to produce and it is not possible to objectively determine the profile parameters of each shell in a batch. For the non-destructive testing of any corrugated shell parameters developed into a universal instrument. The left figure shows the tool to measure the height of the corrugation h. It is fixed with a screw 2 set of 3 micrometer screw 1. A slider 5 is mounted on the movable rod 4 and a needle 6 having a diameter of 0.6 to 0.7 mm is press-fitted onto the slider 5.
