Detailed Description
The technical scheme of the utility model is explained in detail in the following with the accompanying drawings of the specification.
As shown in fig. 1 and 2, the automatic locking and releasing device of the present invention includes a bracket 4, 2 jaws 1, a connecting rod 3, 2 pin shafts 2, a limiting block 7, a knock pin 8, a spring, a driving motor 6, a reversing control module, and a position sensor 5.
Wherein the bracket 4 is used for supporting a fastened piece. The support 4 provides mounting positions for the clamping jaws 1, the driving motor 6 and the like. 2 claws 1 cooperate with a bracket 4 for fixing a fastened piece. The connecting rod 3 is used for transmitting power; the 2 pin shafts 2 are used for positioning the 2 clamping jaws 1, and the inclined pin shafts 2 provide a rotation center for the clamping jaws 1, namely, the guide effect is realized; the limiting block 7 is used for limiting the rotation of the 2 clamping jaws 1; the jack pin 8 jacks the jack catch 1 under the action of the spring; the spring is used for driving the clamping jaw 1 to rotate around the pin shaft 2 and keeping the clamping jaw at an opening position; the driving motor 6 is used for providing power for the up-and-down action of the limiting block 7; the reversing control module is used for controlling the driving motor 6 to perform reversing action; the position sensor 5 is used for detecting the positions of the limiting block 7 and the fastened piece.
The support 4 is fixed on the chassis, and 2 jack catchs 1 pass through round pin axle 2 sliding connection respectively on the upper end of support 4, form the locking circular arc. The upper end of support 4 is arc groove structure, and 2 jack catchs 1 slide in opposite directions support in the arc recess of support 4 upper end to the side of 2 jack catchs 1 is provided with the direction arc wall. 2 round pin axles 2 are fixed respectively on support 4 to the one end of round pin axle 2 and 1 side direction arc wall sliding connection of jack catch, thereby play the guide effect. Stopper 7 installs in support 4 upper end middle part mounting hole to keep with 1 lower part end face contact of jack catch, when being in locking state promptly, the one end of stopper 7 is located between the terminal surface of 2 jack catch 1 lower extremes, and the other end of stopper 7 is connected with driving motor 6's output shaft through connecting rod 3, stopper 7 middle part and support 4 sliding connection, connecting rod 3 and support 4 sliding connection. The spring and the ejector pin 8 are sequentially arranged in the ejector pin mounting hole in the support 4, namely the lower end of the ejector pin 8 is supported by the spring, under the action of the spring, the end parts of the 2 ejector pins 8 are kept in contact with the clamping jaw 1, the driving motor 6 and the reversing control module are fixed on the support 4, and the 2 travel switches are respectively located at the opening limit position and the locking position of the clamping jaw.
The working process of the utility model is as follows:
releasing: when the reversing control module controls the driving motor 6 to provide downward power, the driving motor 6 drives the connecting rod 3 to move downwards, one end part of the limiting block 7 is separated from the end faces of the lower ends of the 2 clamping jaws 1, when the limiting block 7 cannot effectively limit the 2 clamping jaws 1, the 2 clamping jaws 1 slide in the arc-shaped groove in the upper end of the support 4 under the action of the spring, so that the support rotates to be opened, when the support is opened in place, the clamping jaws 1 collide with the travel switch, the travel switch gives an opening in-place signal, and the support can move upwards to be disengaged by a fastening piece;
locking: by fastener accessible adjustment height and direction position, thereby fall into the locking circular arc that 2 jack catchs 1 constitutions through self weight, by the lower extreme of fastener oppression jack catch 1, force 2 jack catchs 1 to slide in the arc recess of support 4 upper end, reach and block by the fastener, by fastener push down travel switch, travel switch gives the push down signal, at this moment, switching-over drive module control driving motor 6 provides the power of upwards moving, connecting rod 3 upwards moves under driving motor 6 drives, connecting rod 3 drives stopper 7 action, and reach limit position, 2 jack catch lower extreme terminal surface spares are inserted to the one end of stopper 7, thereby 2 jack catchs 1 are closed and are locked by the fastener, travel switch gives and closes the position signal, stopper 7 reaches the purpose of locking by the fastener to 2 effective spacing of jack catchs 1.
In the whole action process, the position sensor 5 provides a signal that the clamping jaw 1 is pressed down to the right position, a signal that the clamping jaw 1 is opened to the right position and a signal that the clamping jaw 1 is closed to the right position for the control system, and provides a judgment basis for the action control of the control system.
