我厂生产的柴油机缸盖零件,图纸要求内腔在4公斤水压下不出现泄漏现象。由于毛坯是铸件,以前水压试验必须在九个孔部进行预加工,并粗加工缸盖的四个面后进行,因此,如果试压中发现毛坯废品后,前面的加工工时就白白浪费掉了。为此,我们设计了如图示箱笼式水压试验工具,对毛坯直接进行水压密封性试验,从而节约了加工工时,提高了经济效益。 I plant diesel engine cylinder head parts, drawings required within 4 kg of water pressure does not leak. Since the blank is castings, the previous hydrostatic test had to be pre-machined in nine holes and roughed on the four sides of the cylinder head so that if the scrap was found in the pressure test, the previous working time was wasted It’s To this end, we have designed a box-type hydraulic test tool as shown in the figure, which directly tests the hydraulic pressure tightness of the blank to save the processing man-hours and increase the economic benefits.
