4.Direction of rotation of the gripper arm The STANDARD direction of rotation designation D, as shown below The OPTION designation S is for counter-clockwise output shaft rotation to produce gripper-arm motions in the opposite direction. Fig. 3 Direction of rotation > 5. Danger area Since we are dealing with a repetitive movement mechanism and positive coupling, the gripper arm moves only within its action range. The tool changer mechanism can be stopped only after: overload of the drive motor, reaction of the torque limiting coupling, failure of an internal component or power outage....

6.Examples of applications HTC tool-changers can be used for machine tools with horizontal-axis spindle. Rotation of the grippers to hold the tools (first rotation in the cycle) is clockwise in standard arrangements, but counter-clockwise rotation is available on request. In this case also the grippers must be specified for the counter-clockwise direction of rotation. Note: reversing the direction of rotation of the motor means performing the cycle in reverse order, but does not mean actuating gripping in a counter-clockwise direction. 7.System components The extraction tool system is...

9. Using a self-braking motor A self-braking motor is used to stop the mechanism during a dwell provided at the end of each tool change cycle. It will remain there until the machine control calls for another tool change cycle. To facilitate adjustment and synchronization during installation or for maintenance manual brake release to allow manual drive shaft rotation, is provided. An alternative to self-braking motors, is inverter or vector controlled. These have been used successfully. These motors have no mechanical parts to wear, and allow precies regulation of speed. Another type of...

17. Description of the gripper arm 18. Overall dimensions The tool changer gripper arm consists of a central aluminium structure with terminal tool grippers of hardened steel. Tool gripping and release are obtained by means of a spring-operated mechanism actuated by the rotation of the arm. The latter, in turning, engages or disengages the grippers from the tools when these are in exchange position. While in motion, an irreversible mechanical type safety interlocking device enters automatically into operation and prevents accidental opening of the tool gripper. The gripper arm is attached...
