A rubber ring auxiliary installation tool for split gasket

Abstract

The invention relates to an auxiliary rubber ring installation tool for split gaskets, which includes a tapered seat, a threaded cylindrical push rod, a threaded circular ring post and a bending limit rod. There is a circle in the middle of the tapered seat. The threaded cylindrical push rod passes through the through hole of the tapered seat, and the guide rod is arranged on the outside of the tapered seat, and the threaded circular column and the threaded cylindrical push rod are connected by threads. Four slots are provided on the threaded circular column along the circumference, and the bending limit rod is fixed with the threaded circular column through the slots to limit the upward displacement of the rubber ring when the guide rod is pulled out. Compared with the prior art, the auxiliary installation tool can realize the convenient installation of the split gasket and the rubber ring, has the advantages of simple operation, time saving and labor saving, and is convenient for improving the combined installation efficiency of the split gasket and the rubber ring.

Description

technical field [0001] 本发明涉及土木建筑工程、机械装配技术领域,尤其是涉及一种用于分体式垫片的橡胶圈辅助安装工具。 Background technique [0002] 当前在土木建筑以及机械安装领域,对结构件连接紧固的安装需求量大。尤其是针对封闭截面构件上,需要更加可靠的紧固件实现辅助安装。单边螺栓紧固件可以很好地解决土木建筑以及重要机械中的封闭截面构件紧固问题,中国专利CN111055237A公开了一种铰链式变形收缩自回复单边螺栓紧固件,该专利公开的单边螺栓紧固件的结构特点是四个分体式垫片通过橡胶圈组合在一起,四个分体式垫片结构相似,均为圆心角90度的扇形垫片,对分体式垫片连接处施力可使其收缩变形,撤去力后由于橡胶圈的作用可回复原状。目前该种分体式垫片的装配方式为手工装配,即将分体式垫片组合放置于工作台上,将橡胶圈手动撑大后套在分体式垫片外侧的凹槽内,然而安装过程中,分体式垫片不易定位,容易散落,橡胶圈由于弹性较小,不易于直接用手扩张至需要的直径,无法进行批量快速安装,工作效率低,无法满足市场需求。 Contents of the invention [0003] 本发明的目的就是为了克服上述现有技术存在的缺陷而提供一种用于分体式垫片的橡胶圈辅助安装工具。 [0004] The purpose of the present invention can be achieved through the following technical solutions: [0005] 一种用于分体式垫片的橡胶圈辅助安装工具,用于辅助分体式垫片与橡胶圈的安装,包括锥形座、带螺纹圆柱推杆、带螺纹圆环柱和弯折限位杆,所述锥形座的中央开设有圆形通孔,所述带螺纹圆柱推杆从锥形座中央的圆形通孔穿过,并与位于底部的带螺纹圆环柱活动连接,所述带螺纹圆环柱上沿周向开设多个用以固定安装弯折限位杆的卡槽,所述锥形座外侧周向布置两种长度的导向杆,两种长度的导向杆等间隔依次交错布置。所述弯折限位杆的一端设有与所述带螺纹圆环柱上的卡槽相匹配的卡钩。 [0006] 进一步地,所述带螺纹圆柱推杆与锥形座可通过推拉力实现相对位移,二者的位移距离与分体式垫片的厚度相同。 [0007] 进一步地,所述锥形座的底圆直径与分体式垫片的...

AI Technical Summary

Problems solved by technology

At present, the assembly method of this kind of split gasket is manual assembly, that is, the combination of split gaskets is placed on the workbench, and the rubber ring is manually stretched and then placed in the groove on the outside of the split gasket. However, during the installation process, The split gasket is not easy to locate and is easy to fall apart. Due to the small elasticity of the rubber ring, it is not easy to directly expand to the required diameter by hand, and it cannot be quickly installed in batches. The work efficiency is low and it cannot meet the market demand.
