对油管排放装置传递机构的特点、运动形式和受力状况进行了分析，并通过优化设计得到了该机构主要结构的最优尺寸解，从而满足了油管在传递过程中必须始终保持平动和稳定，同时机构的能耗应最小的设计要求。设计分析表明：1．平行四边形机构可以用于油管传递机构，结构尺寸优化是设计的关键。2．机构中各杆件的长度对传动性能的影响不同，曲柄影响最大，连杆影响最小。3．零件的尺寸精度对机构的受力状态影响较大，最好成对加工。4．在抓放油管时应避开杆件重合位置，以减少冲击。
The characteristics, movement forms and stress conditions of the transmission mechanism of the oil pipe discharge device were analyzed, and the optimum dimension solution of the main structure of the mechanism was obtained through optimization design so as to satisfy that the oil pipe must always be in translation and stability during the transmission , While the organization’s energy consumption should be the minimum design requirements. Design analysis shows: 1. Parallelogram mechanism can be used for tubing transfer mechanism, the structural size optimization is the key to the design. 2. The length of each rod in the mechanism has different influences on the transmission performance, the crank has the greatest influence and the connecting rod has the least impact. 3. Parts of the dimensional accuracy of the force state of the larger impact, the best pair processing. 4. Grasping the oil pipe should be avoided when the rod coincide position to reduce the impact.
