Working principle and using flow:
when the workbench is used, the horizontal table 2 is used for clamping and horizontally rotating, the clutch assembly 3 is used for providing a tilting rotation function of the front and back angles of the workpiece and the horizontal table 2, and the following is adopted: the clutch assembly 3 can rotate and adjust in two directions, and in this case, the rotation directions of fig. 7 and 8 are taken as examples;
firstly, a torque motor 313 is started and drives an input shaft 314 and a friction disk II 315 to rotate, friction force is generated between the friction disk II 315 and the friction disk I33, at this moment, the friction disk I33 has a tendency of driving a clamping column 34 and a movable clamping ring 35 to rotate around the axis of a right supporting table 12, but because the clamping column 34 is limited by a limiting block 310, the stressed movable clamping ring 35 cannot move to the right under the action of a sawn tooth surface of a fixed clamping ring 31, at this moment, the friction disk II 315 and the friction disk I33 slide and rub, but the friction disk II 315 drives a pressing block I316 to rotate while rotating, the limiting block 310 is pushed away and moves towards the inner wall of a connecting ring 37 through the limiting contact of the pressing block I316 and the limiting block 310, a reset spring 39 is compressed until an adapting hole 311 is coincided with the clamping column 34, at this moment, the clamping column 34 is stressed and moves towards the inside of the adapting hole 311, the power from the torque motor 313 is transmitted to the upper surface of the output shaft 32 and a horizontal table 2, and centrifugal force is generated along with the rotation of the friction disk I33 and the connecting ring 37, the limiting block 310 is driven to move towards the direction of the adapting column 38, and the adapting hole 311 is kept coincident with the adapting hole 311;
note that: referring to fig. 8, when the first extrusion block 316 pushes the first limit block 310 to the limit position outwards (the position can ensure that the clamping post 34 is inserted into the adapting hole 311), the first friction disk 33 and the clamping post 34 are released from the clamping limit of the fixed clamping ring 31 and the movable clamping ring 35 and gradually maintain the synchronous rotation speed with the second friction disk 315, the gradually increased centrifugal force of the first limit block 310 can keep the position of fig. 8, and the limit extrusion of the first extrusion block 316 is not needed, after that, the first extrusion block 316 can continue to rotate towards the original direction due to the rotation speed difference between the second friction disk 315 and the first friction disk 33, so that the clamping post 34 cannot be reinserted into the adapting hole 311 due to the reset of the first extrusion block 316 caused by the disappearance of the centrifugal force of the first limit block 310 is avoided;
then, when the torque motor 313 stops, the output power of the clutch assembly 3 disappears, at this time, an inertia moment exists on one side of the output shaft 32 and the first friction disk 33 connected with the horizontal table 2, when the torque motor 313 stops rotating, the centrifugal force generated by the first friction disk 33 and the connecting ring 37 disappears, the limiting block 310 resets under the resilience force of the return spring 39, the clamping column 34 is staggered with the adapting hole 311, the clamping column 34 is limited by the limiting block 310 again, the movable clamping ring 35 is driven to be clamped with the saw tooth surface of the fixed clamping ring 31, one side of the output shaft 32 stops instantaneously, and no inertia moment is generated on the torque motor 313.
It is noted that relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
