连杆螺钉拉伸机设计探讨

Discussion on the design of linkage screw of drawing machine

连杆螺钉在加工完成后成品交验前,要求进行预拉伸试验。在生产现状调研基础上,重点介绍了液压型拉伸机的动力系统设计、专用液压缸设计、双向棘轮扳手设计、测量系统设计方法。该实用新型设计,实现了连杆螺钉的拉伸及伸长量的精确控制,有较好的生产实用价值。

Before completing linkage screw in the machining,finished products are needed to do the pre-tensile test.Based on the research of production status,It focuses on a hydraulic-type stretching machine power system design,special hydraulic cylinder design,two-way ratchet wrench design and measuring system design.The new design has realized stretching and precise control of elongation,which have better value in production and use value.
