A 2nd control ode signal (f) is changed at the time when the 1st signal (a) is inputted. And, a conversion part 21 integrates the incremental value of the turning angle of the spindle again. A 3rd counting part 22 has been counted the 1st signal (a), while the 2nd control mode signal (f) is showing the speed loop mode, so it outputs this count value (m) to a calculation part 23. The calculation part 23 normalizes with the calculation of Pc+mX360 deg.C being performed from the spindle present position Pc of the conversion part 21 and count value (m), renewing the spindle present position Pc stored in the conversion part 21.

Title: Workpiece turning-over device
Inventor: WASHIDA YOSHIAKI
IPC: B23Q7/00
Filed: 1987-12-09
Abstract: PURPOSE:To miniaturize a workpiece turning-over device, improve the operability and reduce shocks given to the workpiece in an emergency stop by changing the position of a workpiece mount guided by a link and guide between generally horizontal and perpendicular positions. CONSTITUTION:Links 38, 38 are rotated clockwise as a bridge body 30 is moved horizontally so that the other end A side of a workpiece mounting bed 30 is lifted upward. When said bed reaches the vertical position the rotation of a motor 28 is stopped and the assemblage and maintenance or the like of workpiece are resumed in said position. Since one end A of the workpiece mounting bed 30 is lifted while the other end is moved horizontally, the horizontal displacement of workpiece turned over is reduced. Thus, the whole device can be miniaturized. Also, a jig does not need to be largely moved to improve the operability. Further, since the movement is reduced, shocks applied to the workpiece in an emergency stop can be reduced.
