Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 4 shows, this utility model provides a kind of actuating device preventing power transmission shaft from can stop transmission when overload occurs.This device is mainly by drive block 1, power transmission shaft 3, sensing slide block 4 and reed 2 form, and be provided with external screw thread 31, the front end face of drive block 1 is provided with chute on power transmission shaft 3, chute in the present embodiment is arranged to dovetail groove, meanwhile, this chute can also be arranged to T-slot, when being arranged to T-slot, sensing slide block correspondence both sides are the boss suitable with T-slot, and sensing slide block is slidably arranged in T-slot by boss.The corresponding two sides of sensing slide block 4 are the inclined-plane suitable with dovetail groove, sensing slide block 4 is slidably arranged in dovetail groove by this inclined-plane, sensing slide block 4 is provided with the diameter driving hole more than power transmission shaft 3, this driving hole can be arranged to different shapes, such as circular hole, mounting hole and square hole, need to ensure that power transmission shaft can pass through this driving hole.Driving hole in the present embodiment is arranged to circular hole 42, circular hole 42 side hole wall along sensing slide block 4 direction of motion is provided with female thread block 5, female thread block 5 is provided with the female thread 51 suitable with external screw thread on power transmission shaft 31, external screw thread 31 on power transmission shaft 3 engages each other with the female thread 51 on the female thread block 5 on sensing slide block, drive block 1 is provided with a through hole 11, this through hole 11 is arranged on the groove bottom 12 of dovetail groove, and the through drive block 1 in trailing flank direction, and connect with the circular hole 42 on sensing slide block 4, power transmission shaft 3 is rotatably through circular hole 42 and through hole 11, such as Fig. 3.
Reed 2 is fixed on the one side of drive block 1, reed 2 is bent into the projection 21 of an elastically deformable, one end is fixed on drive block 1, the other end forms elastic free end, this elastic free end is placed in the square hole 41 being arranged on sensing slide block 4, and be pressed on the side hole wall of square hole 42, make to be connected on sensing slide block 4 female thread block 5 tightly engaged by internal and external threads with power transmission shaft 3.
Power output shaft is connected with power transmission shaft 3, the rotation of power output shaft drives power transmission shaft 3 to rotate, owing to the female thread block 5 on sensing slide block 4 keeps engaging with the external screw thread 31 on power transmission shaft 4, the rotation of power transmission shaft 3 can drive sensing slide block 4 and move with the sensing drive block 1 that is connected of slide block 4, and controlled drive block 1 by rotating and reverse of power transmission shaft 3 and sensed forwardly and rearwardly moving of slide block 4.
nullIn drive block 1 motor process，When the retard motion of drive block 1，Owing to the female thread 51 of female thread block 5 on sensing slide block 4 is to be suppressed by reed 2 and external screw thread 31 on power transmission shaft engages，When sensing slide block 4 stop motion，Now power transmission shaft 3 still persistently keeps power to provide and rotate，The rotation of power transmission shaft 3 overcomes the elastic force of the bossing 21 of elastically deformable on the reed 2 of compacting sensing slide block 4，The elastic free end of reed 2 drives sensing slide block 4 outwards to eject，Female thread block 5 is disengaged from the external screw thread groove on power transmission shaft 3，Power transmission shaft 3 is rotated further，When power transmission shaft 3 turns an angle，The elastic force of projection 21 part of the elastically deformable that sensing slide block 4 is subject on reed 2，Elastic free end again rebounds and suppresses sensing slide block 4，Female thread block 5 falls in the external screw thread groove on power transmission shaft 3 again，Again engage.Repeat said process, the telescopic process of sensing slide block 4 is driven by reed 2, ensure that power transmission shaft 3 and sensing slide block 4 remain the engagement of intermittent repetition and be disengaged from action, ensure that power transmission shaft 3 continues to rotate, prevent from causing the external screw thread 31 on power transmission shaft 1 owing to drive block 1 and sensing slide block 4 stop moving and engaging stuck between female thread block 5, power transmission shaft 3 stops operating, and makes power output shaft transship, power output shaft is caused damage.
