The rocker arm type dimple limiting device comprises a taper pad, a general dimple limiting stopper, a hoop, a rocker arm rod, a sliding block and a positioning pin, the taper pad is connected with a port of the general dimple limiting stopper, one end of the taper pad is of an inclined plane structure, the hoop is arranged on the dimple limiting stopper in a sleeving mode, a sliding groove is formed in the middle of the rocker arm rod, and the sliding block is arranged in the sliding groove. The sliding block can move to a designated position along the sliding groove, and the positioning pin is fixed to the bottom of the sliding block and is in hole-shaft fit with a positioning hole in the long-axis direction of the to-be-dimpled oval countersunk head nest. The taper pad is additionally arranged on the basis of a general dimple limiting stopper to meet the dimple angle requirement of a mounting hole, meanwhile, the rocker arm rod and the positioning pin are used for positioning, the consistency of the oval dimple in the long axis direction is guaranteed, the taper pad, the positioning pin and the rocker arm rod can be replaced according to the specification of the oval dimple, the application range is wide, and the practicability is high. And the structure is simple, operation is convenient, and the manufacturing requirement of the oval countersunk nest can be met.

    本发明公开了一种用于椭圆沉头窝的摇臂式锪窝限位装置及锪窝方法,该装置包括锥度垫、通用锪窝限位器、卡箍、摇臂杆、滑动块、定位销,锥度垫与通用锪窝限位器端口连接,一端为斜面结构,卡箍套装在锪窝限位器上,摇臂杆中间设有滑动槽,滑动块可沿滑动槽移动到指定位置,定位销固定在滑动块底部并与待锪窝的椭圆沉头窝沿长轴方向上的定位孔孔轴配合。本申请是在通用锪窝限位器的基础上增加锥度垫实现安装孔锪窝角度要求,同时利用摇臂杆和定位销进行定位,保证椭圆窝长轴方向上的一致性,其锥度垫、定位销和摇臂杆均可根据椭圆沉头窝的规格进行更换,适用范围广,并且结构简单、操作方便,能够满足椭圆沉头窝的制取需求。
