Specific embodiment

Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other It can be combined with each other.

Referring to Fig. 1 and Fig. 2, present embodiment discloses a kind of quick bidirectional fork mechanism, including servo-drive electricity 100, two, machine big 106, two small swing arms 107 of swing arm and feeding pallet 108, the big swing arm 106 of two of them and two small swing arms 107 one end rotation connection, the other end of two big swing arm 106 is set together, the other end of two small swing arm 107 respectively with Feeding pallet 108 is rotatablely connected, so that two big swing arm 106 and two small swing arm 107 surround quadrangle, and small swing arm 107 It is stacked above big swing arm 106.Feasible, big swing arm 106 is internally provided with driving member, including driving gear 101, passive Gear 102, the first synchronous pulley 103, synchronous belt 104 and the second synchronous pulley 105, driving gear 101 be located at big swing arm 106 with At the rotation axis that servo drive motor 100 connects, one of those driving gear 101 and servo of two two big swing arm 106 Driving motor 100 is sequentially connected, engaged transmission between the driving gear 101 of two big swing arm 106.Driving gear 101 and passive 102 engaged transmission of gear, the first synchronous pulley 103 are stacked with driven gear 102, the first synchronous pulley 103 and passive tooth Wheel 102 is fixedly connected or is integrally formed, and is passed between the first synchronous pulley 103 and the second synchronous pulley 105 by synchronous belt Dynamic, the second synchronous pulley 105 is located at the connection shaft of big swing arm 106 and small swing arm 107, the second synchronous pulley 105 and the two Connection rotation axis rotate synchronously, and rotation axis is able to drive big swing arm 106 and small swing arm 107 and relatively rotates, feasible, can To be that rotation axis both ends are fixed with the two respectively, and are provided with bearing among rotating.

Working principle of the utility model is: when servo motor 100 drives driving gear 101 to rotate clockwise, big swing arm 106 and driving gear 101 be fixed together, while also rotating clockwise；Driven gear 102 does rotation counterclockwise, synchronous belt One 103 and the fixation of driven gear 102 are taken turns, and then synchronous pulley 1 also does rotation counterclockwise；Synchronous pulley 1 passes through same Step band 104 drives synchronous pulley 2 105 to rotate counterclockwise；Synchronous pulley 2 105 and small swing arm 107 are fixed, and then small swing arm 107 also rotate counterclockwise, and since the transmission ratio of big swing arm 106 and small swing arm 107 is 1:1, and spindle central is away from identical, so Feeding pallet 108 can be made to do straight line retraction movement when small swing arm 107 rotates counterclockwise.As a same reason, when servo motor 100 When driving gear 101 being driven to rotate counterclockwise, feeding pallet 108 can be made to do straight line stretch out motion.Pass through big swing arm and small pendulum Being driven by rotation for arm, can be realized the spreading angle of the two, can be realized bidirectional displacement, and the components of equipment are less, if Standby cost is relatively low, and translates not extra stroke, and speed is fast, stable.

The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
