Rotary type of positioning pin hole anchor clamps pushes away by structure

The utility model discloses a rotary type of positioning pin hole anchor clamps pushes away by structure belongs to machining equipment technical field. Include the hydro -cylinder and push away by the lever, pushing away and leaning on the lever to rotate around the center, the piston rod surface of hydro -cylinder is equipped with the recess, and the one end that pushes away by the lever is located the slot that the recess is interior, the other end is located the backup arm bottom, backup arm rotates around the center pin. The beneficial effects of the utility model are that: pass through hydro -cylinder and backup arm effectively to have shortened pushing away the length by the device around the rot. Lever operation of the heart, be applicable to arranging and using in narrow and smallspace. 本实用新型公开了种销孔定位夹具的转动式推靠结构，属于机械加工设备技术领域。包括油缸和推靠杠杆，所述推靠杠杆绕中心转动，油缸的活塞杆表面设有凹槽，推靠杠杆的端位于所述凹槽内、另端位于推靠臂底部的插槽内，所述推靠臂绕中心轴转动。本实用新型的有益效果是：将油缸和推靠臂通过绕心回转的杠杆传动，有效缩短了推靠装置的长度，适用于在狭小空间内的布置和使用。
