The invention relates to the field of operation machinery, and discloses a counterweight assembly and operation machinery. The counterweight assembly comprises a connecting rod, the connecting rod extends in the first direction, a connecting hole is formed in the connecting rod and used for being connected with a positioning hole of the counterweight mounting frame, the axis of the connecting hole intersects with the first direction, and an annular groove is formed in the outer side wall of the connecting rod; the base is provided with a mounting hole allowing the connecting rod to penetrate, the mounting hole extends in the first direction, the clamping piece is connected with the base, the clamping piece is arranged in the annular groove and is in sliding fit with the annular groove, and the clamping piece is used for limiting the annular groove in the first direction. When the clamping piece limits the connecting rod in the first direction, the connecting rod cannot be circumferentially limited, so that the connecting rod can freely rotate in the mounting hole, the orientation of the connecting hole is conveniently adjusted, the parallelism error of the axis of the connecting hole and the axis of the positioning hole is reduced, and the machining precision is improved. The problem that the first positioning piece cannot be inserted into the connecting hole and the positioning hole is avoided or improved.
本发明涉及作业机械领域,公开了配重总成及作业机械。配重总成包括:连接杆,连接杆沿第一方向延伸,连接杆上设有连接孔,连接孔用于与配重安装架的定位孔相连,连接孔的轴线与第一方向相交,连接杆的外侧壁上设置有环形槽;底座和卡接件,底座设有供连接杆穿入的安装孔,安装孔沿第一方向延伸,卡接件与底座相连,卡接件置于环形槽,并与环形槽滑动配合,卡接件用于在第一方向上,对环形槽限位。卡接件在第一方向上对连接杆限位时,并不会对连接杆形成周向限位,使得连接杆能够在安装孔内进行自由转动,以便于调整连接孔的朝向,降低连接孔与定位孔二者轴线的平行度误差,避免或改善第一定位件无法插入连接孔和定位孔的问题。
