机械传动联轴节或平面连接定位,通常采用圆柱销或圆锥销。如遇有振动或冲击的情况,仅凭这种单一定位的方法是远远不够的,还必须辅以限制圆销滑脱的防松装置,如加以销端挡板和螺母锁紧等。采用这种措施,一般来说防松问题可得以解决,但结构较复杂,用工增加,不利于劳动生产率的进一步提高。这里介绍的开口圆销,是一种用弹簧钢板制成的新型定位件。它由两个开口圆管组成,其工艺加工过程是:先按所需尺寸将钢板卷圆,然后再让不同孔径的两个圆管套
Mechanical transmission coupling or plane connection positioning, usually cylindrical pin or tapered pin. In case of vibration or impact, this single positioning method alone is not enough. It must be complemented by locking devices that limit the slippage of the pins, such as pin baffles and nut locks. With this measure, in general, the problem of anti-loosening can be solved. However, the structure is complicated and the employment is increased, which is not conducive to the further improvement of labor productivity. The open-ended pin introduced here is a new type of positioning element made of spring steel plate. It consists of two open pipe, the process is: first press the required size of steel round, and then let the different diameter of the two sets of pipe
