我厂为某发动机公司配制一种机油尺组件中的机油尺导管,导管和箱体直接联接,联接处要求密封。在生产过程中,我们采用轴向密封方式,即发动机箱体的孔、机油尺导管的凹槽与“0”型密封圈实现密封。为达到良好的密封效果,特别研制了一种加工导管的新型滚压工具。从产品图纸(... I plant for the engine company formulated a dipstick oil dipstick assembly of the catheter, the catheter and the box directly connected to the joint requirements of the seal. In the production process, we use the axial seal, that is, the hole in the engine casing, dipper duct groove and the “0” type seal to achieve sealing. In order to achieve a good sealing effect, in particular, developed a new type of catheter rolling tool. From product drawings (...
