卷烟机油封安装辅助工装的设计与运用

Design and Application of Auxiliary Tooling for the Installation of Oil Seals of Cigarette Machines

摘要: 为了解决目前卷烟机油封安装不便，安装精度差的问题，本文设计了一种用于卷烟机油封安装的辅助工装，包括安装杆、导向套和压装件，安装杆用于嵌套油封平面，端部设置有限位块，导向套端部为圆台状，用于嵌套油封凹槽面，压装件包括法兰和压套，压套插入安装在油封凹槽面。安装杆可以实现较小口径油封的拿取和固定，导向套将油封在法兰座内准确定位并固定，通过压装件使油封均匀受力完成安装，安装过程中施加在油封上的力传递均匀，避免不均匀的力量对油封造成的弹性形变，确保油封在安装过程中能够保持其原有形状和尺寸。工装辅助安装较小口径的油封时，改善了常规安装方式难以拿取油封和产生弹性形变的问题，使油封的安装过程更加简单和高效，因此，该工装具有较好的实用性。

Abstract: In order to solve the problem of inconvenient installation and poor installation accuracy of the current cigarette machine oil seal, this paper designs an auxiliary tooling for the installation of the oil seal of the cigarette machine, comprises a mounting rod, a guide sleeve and a press-fitting part, the mounting rod is used for nesting the oil seal plane, the end part is provided with a limiting block, the end part of the guide sleeve is round-table-shaped, which is used for nesting the oil seal groove surface, the press-fitting part comprises a flange and a pressure sleeve, and the pressure sleeve is inserted and installed on the groove surface of the oil seal. The mounting rod can realize the taking and fixing of the smaller diameter oil seal, the guide sleeve accurately locates and fixes the oil seal in the flange seat, makes the oil seal evenly stressed through the press-fitting to complete the installation, and the force exerted on the oil seal is transmitted evenly during the installation process, so as to avoid the elastic deformation caused by the uneven force to the oil seal, and ensure that the oil seal can maintain its original shape and size during the installation process. When the tooling assists in installing the oil seal of smaller diameter, the problem that the conventional installation mode is difficult to take the oil seal and produces elastic deformation is improved, and the installation process of the oil seal is more simple and efficient, therefore, the tooling has good practicability.
