| 针对国产带锯床中普遍存在的张紧装置设计不合理导致装置失效、张紧力不恒定等问题，对张紧装置进行了需求分析，建立功能原理模型，通过综合对比各功能原理解确定了采用精度高、张紧力可保持恒定的螺纹张紧方式，设计了由张紧滑块和张紧丝杆等组成的装置结构，通过计算确定了扭力扳手力矩、张紧丝杆直径等关键部件参数，并利用有限元软件ANSYS Workbench对装置结构进行了有限元分析。结果表明：设计的张紧装置满足强度要求，装置结构设计紧凑，张紧力可保持恒定。该设计在一定程度上可提高锯切精度及锯条的寿命，可应用于大多数带锯床，具有较高的工程应用价值。 |

| Aiming at the problem of the unreasonable design of tensioning device in band sawing machine which cause structural failure and unsteady tension force, the requirement analysis was carried out, then functional principle model was established, the thread tension mode was used in the design which could keep high precision and constant tension force through the comprehensive comparison of each principle solution.the structure scheme was designed which were composed of tension slide block and tension wire rod, the key components such as torque wrench torque, tension wire rod diameter were determined by calculation. then the device was analyzed by using the software of Workbench ANSYS. The results indicated that the tensioning device met the strength requirements and had compact structure , and the device also could maintain a constant tension force. To a certain extent it could improve the cutting precision and the life of the saw blade , and it could be applied to most of the band sawing machines. all of results showed that this research had high engineering application value.
