摘　　要：针对上一代建筑墙面砂浆抹灰机的喷涂模块结构复杂、运行不稳定及施工效率低等问题,创新设计了一种结构简单、性能稳定的摆动喷涂机构。通过直线导轨滑块与丝杆、滑台的联动作用,实现砂浆喷涂摆臂的摆动。利用SolidWorks软件创建了摆动喷涂机构的三维模型,并对喷涂机构进行运动学分析;采用机械系统的动力学自动分析(automated dynamic analysis of mechanical systems,ADAMS)软件对喷涂机构进行运动仿真,得到了砂浆喷涂摆臂的运动学特性以及砂浆轨迹;制作出摆动喷涂机构样机并安装在抹灰机上,进行砂浆喷涂现场实验。实验结果表明:摆动喷涂机构设计合理,其结构简单、运行稳定、施工效率高;喷涂出的砂浆连续且均匀,其轨迹基本趋近于一条直线,砂浆喷涂施工质量较高。采用摆动喷涂机构喷涂的建筑墙面砂浆抹灰机具有较好的应用前景。A simple structure and stable performance swing spraying mechanism was innovatively designed to address the complex structure,unstable operation,and low construction efficiency of the spraying module of the previous generation of building wall mortar plastering machines.The swing of the mortar spraying swing arm was achieved through the linkage between the linear guide rail slider and the screw and slide table.A 3D model of the oscillating spraying mechanism was created using SolidWorks.The dynamic automatic analysis of the mechanical system using ADAMS(automated dynamic analysis of mechanical systems)software was used to simulate the motion of the spraying mechanism.The kinematic characteristics and trajectory of the mortar spraying swing arm were obtained.A prototype of a swing spraying mechanism was made and installed on a plastering machine for on-site mortar spraying experiments.The experimental results showed that the swing spraying mechanism was designed reasonably,with a simple structure,stable operation,and high construction efficiency.The sprayed mortar was continuous and uniform,and the trajectory tended to be close to a straight line.The quality of mortar spraying construction was relatively high.The construction wall mortar plastering machine using the swing spraying mechanism has good application prospects.
