Title: Locking apparatus for lock-nut in the end of axle
Inventor: YOON JAE HONG
IPC: B23Q7/10
Filed: 2000-04-28
Abstract: PURPOSE: A connecting nut locking device is provided to improve productivity by reducing time for locking and to prevent an accident due to manual operation by automatically locking a cylindrical body on the outer face of a locking groove. CONSTITUTION: Upon lifting up of a body(100), a microswitch(22) applies an electrical signal to a controller(52). The controller controls a drive motor(41) to rotate an upper case. An interlock gear(43) rotates with a rotating cylinder(44). Thus, the upper case placed in the upper portion of the rotating cylinder rotates. A sensing unit(21a) of a second rotating member(21) rotates below an axle terminal. If the sensing unit is placed in a locking groove, the sensing unit is inserted into the locking groove. Upon rotation of the second rotating member, a press roll(22a) is pressurized and an electrical signal is transmitted to the controller. With the electrical signal, a piston rod(31a) of a locking cylinder(31) is transferred downwardly. A rotating arm(32a) linked to a first rotating shaft(32) and a connecting member(4) rotates upwardly by centering on the first rotating shaft. The rotating arm hits a weight(38) in the lower end of a shaft(33) via a transfer member(39). Then, the shaft is lifted up instantaneously while lifting up a contact part(34a) of a first rotating member(34). The first rotating member rotates, and the shaft is returned to the original position by the weight. Since an insertion part(34b) of the first rotating member is inserted into an insertion groove, a hitting member(35) rotates by centering on a third rotating shaft. A hitting part(35b) of the hitting member is placed with a second rotating member(21a) on the same straight line while rotating outside a cylindrical body. Simultaneous with rotation of the hitting member, the cylindrical body is locked in the locking groove.
