装拆活塞环一般是手工进行,生产批量大时,尤为费工。采用活塞环装拆气动夹具后,可提高工效2～3倍,也防止了活塞外径的拉毛,保证了质量。夹具结构见图1,是由双向配气阀3、活塞环撑开机构。气缸26和夹具体6等零部件组成。双向配气阀分别向气缸输送气体。活塞环撑开机构是使活塞环撑开或缩回,其下端与活塞杆25连接,借气体的推动使气缸内的活塞和活塞杆作上下运动;上端通过与弧形叉11相联的连接座14使弧形叉(左右各二件)在夹具体6(图2为装拆)95柴油机活塞环夹具体)与座15组成的滑槽中作回转运动。弧形叉11通过其端部的勾板12使活塞环撑开或缩回,便于活塞从活塞环孔内通过,完成装、拆操作。夹具体的制造必须考虑到被撑开活塞环在自由状态时的开口,以及被撑
Assembly and disassembly of the piston ring is generally carried out by hand, when the production volume is large, especially fatigued. Piston ring demolition pneumatic clamp, can improve work efficiency 2 to 3 times, but also to prevent the piston outer diameter of the hair, to ensure the quality. Fixture structure shown in Figure 1, is a bi-directional valve with 3, piston ring distraction mechanism. Cylinder 26 and clamp body 6 and other components. Bi-directional gas distribution valve to the cylinder respectively. Piston ring expansion mechanism is to open or retract the piston ring, the lower end of the piston rod 25 is connected by the gas to promote the cylinder piston and piston rod for up and down movement; the upper end of the connection with the curved fork 11 Seat 14 so that the arcuate fork (left and right pieces) in the clamp body 6 (Figure 2 for disassembly) 95 diesel piston ring clamp body) and the seat 15 composed of the chute for rotational movement. Arcuate fork 11 through the end of the hook plate 12 so that the piston ring distraction or retraction, easy piston from the piston ring hole through to complete the installation, demolition operations. The manufacture of the clamp must take into account the opening of the piston ring when it is in its free state,
