| 摘要为了解决枪械试验中靶标装夹繁琐、弹着点调整不便等问题，需要设计一个三向可调靶架以提高试验效率，减轻试验人员负担。该靶架的三向可调功能由蜗杆传动机构，丝杠传动机构和液压升降平台三部分组成。蜗杆传动机构实现靶架水平旋转功能，丝杠传动机构调节其水平方向的移动，液压升降平台实现沿高度方向的调整。夹具的快速装夹实现是通过将螺栓紧固改进成把手，这样既可以提高实验效率，又能减少扳手等工具的使用。设计了两种旋转、水平移动平台的布置方案，并给出了详细的设计计算过程。对比了两种不同升降平台的优缺点。通过UG软件绘制各零件的三文图，最后装配出靶架的整体模型。25594 毕业论文关键字靶架；蜗杆传动；丝杠传动；升降平台；夹具 Title The design and analysis of three degree of freedom target frame Abstract In order to solve the gun test targets clamping and impact area to adjust the inconvenience complicated issues, need to design a three-DOF supporting frame in order to improve the test efficiency, reduce burden of experiment personnel. The three to the adjustable function of supporting frame is composed of three parts: worm drive, the lead screw transmission, lift platform. Worm drive function of supporting frame horizontally rotating lead screw drive to adjust the level of the direction of movement, lift platform to realize the adjustment along the height direction. Clamping fixture rapid implementation is by putting a bolt fastening improvement into his hand, which can improve the efficiency of the experiment, and can reduce the use of tools such as wrench. Gives two kinds of rotation, horizontal layout scheme of the mobile platform, and gives the detailed design and calculation process. Comparing the advantages and disadvantages of the two kinds of different lift platform. Through the UG software to map the various components of the three-dimensional, final assembly out of the whole model of the target frame.
