我厂质量检验组的同志,为了提高活塞环的检验质量,改制了一种简易活塞环张力测定器。它的特点,结构简单、使用方便,其结构如图所示。它主要用一个0—50公斤的秤4,放在底座2上。底座2的左端装有支板1,支板上钻有一个孔,压杆5的一端插入孔内,压杆5用来揿压环径,能测定直径30～500毫米活塞环的张力。使用测定器时,只将被测的活塞环3放在秤4上,然后将压杆5压在活塞环3上。活塞环3放置时,活塞环口应处于水平位置。压动压杆5,使活塞环口趋向闭合。此时环口中间放一金属垫片,片厚为活塞环装入气缸后的环口间隙。当活塞环口压至金属垫片而闭合时,
I plant quality inspection team comrades, in order to improve the quality of the piston ring inspection, restructuring a simple piston ring tension tester. Its characteristics, simple structure, easy to use, its structure as shown. It mainly uses a 0-50 kg scale 4, on the base 2. The left end of the base 2 is provided with a support plate 1, a hole is drilled on the support plate, one end of the pressure rod 5 is inserted into the hole, the pressure rod 5 is used to suppress the ring diameter, and the tension of the piston ring with the diameter of 30 to 500 millimeters can be measured. When using the measuring device, only the piston ring 3 to be measured is placed on the scale 4 and the pressure rod 5 is pressed against the piston ring 3. Piston ring 3 is placed, the piston ring mouth should be in a horizontal position. Pressed the pressure rod 5, the piston ring mouth tends to close. At this point in the middle of a ring metal gasket placed, the thickness of the piston ring into the cylinder after the ring gap. When the piston ring mouth pressure to the metal gasket and closed,
