曲轴钻孔固定工装
本技术涉及一种曲轴钻孔固定工装。
技术介绍
曲轴是发动机中最重要的部件。它承受连杆传来的力,并将其转变为转矩通过曲轴输出并驱动发动机上其他附件工作。曲轴受到旋转质量的离心力、周期变化的气体惯性力和往复惯性力的共同作用,使曲轴承受弯曲扭转载荷的作用。因此要求曲轴有足够的强度和刚度,轴颈表面需耐磨、工作均匀、平衡性好。曲轴在生产过程中,需要利用工装夹具将曲轴夹紧固定,然后在曲轴上开孔。现有技术中,该工装夹具结构复杂,且使用不方便,降低了对曲轴固定以及钻孔的效率,因此存在着改进的空间。
技术实现思路
针对现有技术的不足,本技术提供了一种曲轴钻孔固定工装。为实现上述目的,本技术提供了如下技术方案:一种曲轴钻孔固定工装,包括定位座、定位气缸、定位杆和定位块;所述定位座上具有上下延伸的定位槽一和水平延伸的定位槽二,定位槽一和定位槽二相交;所述定位座的顶部开设有校准孔,所述校准孔向下延伸与定位槽二连通,所述校准孔内设有校准套管;所述定位气缸安装于定位座的背面,且定位气缸的活塞杆穿过定位座与定位杆连接,并驱动定位杆移动;所述定位块连接于定位杆的端部,并且定位块与定位槽一对应。优选的,定位气缸的活塞杆上开设有连接孔一,定位杆上开设有通孔和连接孔二,定位气缸的活塞杆插接于通孔内,并且连接孔一与连接孔二对接并穿设有定位销。优选的,所述定位槽一的槽壁上具有硬质合金块。优选的,所述定位槽一的侧壁上开设有嵌槽,所述硬质合金块固定于嵌槽内。本技术的优点为:固定曲轴时,曲轴的前端以及轴颈位于定位槽一内,曲柄臂位于定位槽二内,启动定位气缸,定位气缸拉动定位块,使定位块压紧在曲轴上 ...
