Patent number: 5657523Abstract: A positioning mechanism of a turret index which performs index rotation by the use of an index mechanism to transmit output shaft motion and perform positioning by a three-piece toothed coupler. The present invention uses a hydraulic system to control the division and the combination of the three-piece toothed coupling to attain the turret's precise positioning and comprises a piston ring on the output shaft. The area of the piston ring's end plane which is subjected to hydraulic pressure, is greater than the area of the slider's end plane inside the three-piece toothed coupler and its end plane is also subjected to hydraulic pressure. At the same time the three-piece toothed coupler is in meshing, the output shaft can obtain an inward pulling force to prevent the output shaft from propping up only a very small distance.Type: GrantFiled: November 2, 1995Date of Patent: August 19, 1997Assignee: Industrial Technology Research InstituteInventors: Ching-Yuan Lin, Win-Jim Su

Patent number: 5386743Abstract: In a turret indexing device, a coupling containing three gear members is employed in a turret indexing device to cooperate with an indexing disc mounted on an output shaft which is adapted to hold an indexing head. The coupling is operated by a first cam fixedly mounted on an input shaft through a lever mechanism, and the indexing disc is driven by a second cam fixedly mounted on the same input shaft. The three gear members include a first gear member fixedly mounted on a collar slidably mounted on the output shaft, a second gear member which is fixedly mounted on a stationary housing, and third gear member fixedly mounted on a head end of the output shaft.Type: GrantFiled: July 13, 1993Date of Patent: February 7, 1995Assignee: Industrial Technology Research InstituteInventors: Win-Jim Su, Ching-Yuan Lin, Jung-Hong Huang
