The invention relates to a stepless hole position adjusting structure. The hole position adjusting structure comprises a base (1), an eccentric outer hole lining (2), an eccentric inner hole lining (3) and a self-locking nut. The structure of the eccentric inner hole bushing (3) is the same as that of the eccentric outer hole bushing (2), an axial eccentric through hole is formed in the eccentric outer hole bushing (2), a convex shoulder is arranged at one end of the eccentric outer hole bushing (2), the other end of the eccentric outer hole bushing (2) penetrates through a central mounting hole of the base (1), and the eccentric outer hole bushing (2) is fixedly connected with the base (1) through a self-locking nut; one end of the eccentric inner hole bushing (3) penetrates through the eccentric through hole in the eccentric outer hole bushing (2) from the convex shoulder end of the eccentric outer hole bushing (2), and the eccentric inner hole bushing (3) is fixed with the eccentric outer hole bushing (2) through a self-locking nut. Stepless adjustment in the whole circle range is achieved, the structure is simple, the assembly difficulty and cost are reduced, the assembly efficiency is improved, and later part exchange and maintenance are guaranteed.

    本发明涉及一种可无级调整孔位结构,该调整孔位结构包括基座(1)、偏心外孔衬套(2)、偏心内孔衬套(3)和自锁螺母;偏心内孔衬套(3)的结构与偏心外孔衬套(2)的结构相同,偏心外孔衬套(2)上设置有轴向偏心通孔,偏心外孔衬套(2)的一端设置有凸肩,偏心外孔衬套(2)的另一端穿过基座(1)的中心安装孔,偏心外孔衬套(2)通过自锁螺母与基座(1)固定连接;偏心内孔衬套(3)的一端从偏心外孔衬套(2)的凸肩端穿过偏心外孔衬套(2)上的偏心通孔,偏心内孔衬套(3)通过自锁螺母与偏心外孔衬套(2)固定。本发明实现了整圆范围内无级可调,结构简单,降低装配难度和成本、提高装配效率,保障后期部件互换和维修。
