Rotary dotting mechanism

The utility model relates to the technical field of dotting mechanisms, in particular to a rotary dotting mechanism which comprises a mounting vertical plate, an up-down adjusting and fixing unit, an advancing dotting unit and a rotating unit, the advancing dotting unit is mounted at the top of the mounting vertical plate, and the mounting vertical plate is slidably mounted on one side of the mounting vertical plate; and a rotating unit and a follower mounting plate are mounted at the top of the forward dotting unit. By adjusting the fixing unit, the forward dotting unit and the rotating unit up and down, machined and detected products such as a pump body of an automobile fuel pump can be confirmed clearly, the mechanism design structure is compact, and space is saved. 本实用新型涉及打点机构技术领域，具体为一种旋转打点机构，包括安装立板、上下调整固定单元、前进打点单元和旋转单元，所述安装立板的顶部安装有前进打点单元，所述安装立板的一侧上滑动安装有安装立板，所述前进打点单元的顶部安装有旋转单元和随动器安装板。本实用新型通过上下调整固定单元、前进打点单元和旋转单元，可以对加工、检测的产品进行明确、清晰的确认，例如汽车燃油泵的泵体，机构设计结构紧凑，节省空间。
