fig. 3 is a bottom view of the gripping member of the present invention.

In the figure: 10. a drive cylinder; 11. a push rod; 20. grasping the part; 21. a pulley; 22. a grasping unit; 23. a connecting arm; 30. a guide bar; 40. a guide groove plate; 41. a guide groove; 42. a guide rail; 50. and (4) a transformer bushing.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

As shown in fig. 1, fig. 2 and fig. 3, the utility model discloses a transformer bushing picks mechanism, including actuating cylinder 10, guide slot plate 40, guide arm 30 and grabbing piece 20, there are five grabbing pieces 20 in this embodiment altogether, can snatch five transformer bushings 50 simultaneously. The grabbing member 20 comprises a pulley 21, a grabbing unit 22 and a connecting arm 23, wherein the pulley 21 is arranged at the bottom of the connecting arm 23, two through holes are formed in two sides of the main body of the connecting arm 23, and a guide rod 30 vertically penetrates through the through holes to be connected with the connecting arm 23. The grabbing unit 22 is provided with a grabbing head, the grabbing unit 22 drives the grabbing head to open and close, the center of the transformer bushing 50 is hollow, and the grabbing head penetrates through the center of the transformer bushing 50 to grab the transformer bushing. The driving cylinder 10 can be a pneumatic cylinder, a hydraulic cylinder or an electric cylinder, and the driving cylinder 10 pushes the push rod 11 to perform piston motion. Guide rails 42 are connected to both sides of the guide groove plate 40, and the push rod 11 pushes and pulls the guide groove plate 40 so that the guide groove plate 40 can linearly reciprocate along the guide rails 42. The slot guide plate 40 is provided with a plurality of scattering-type guide slots 41, and the number of the guide slots 41 is equal to the number of the grasping members 20. Taking fig. 1 as an example, the leftmost guide groove 41 is parallel to the guide groove plate 40, the other guide grooves 41 are inclined by 10 ° to 15 ° in sequence, the pulley 21 is slidably connected to the guide groove 41, and the single grasping member 20 is connected to the single guide groove 41. When the driving cylinder 10 pushes the guide groove plate 40 to move, the pulley 21 slides along the guide groove 41, and when the pulley 21 slides on the guide groove 41 which is obliquely arranged, the grabbing piece 20 is subjected to moving forces in the left and right directions relative to the guide groove plate 40, and under the stability of the guide rod 30, the acting forces in the up and down directions are counteracted, so that the grabbing piece 20 only moves leftwards or rightwards, and the pulley 21 drives the grabbing piece 20 to make horizontal linear motion on the guide rod 30. As shown in fig. 2, when the driving cylinder 10 pulls the chute plate 40 toward the driving cylinder 10, the pulley 21 slides toward the driving cylinder 10, the distance between each grasping member 20 gradually increases and the distance between the grasping members 20 is the distance of a single containing cell of a tray for containing the transformer bushing 50, and the plurality of grasping members 20 can grasp the transformer bushing 50 when being expanded to the diameter of the transformer bushing 50. When the driving cylinder 10 pushes the guideway plate 40 in the opposite direction, the pulley 21 slides in the opposite direction of the driving cylinder 10, the distance between each grabbing piece 20 gradually decreases to realize the folding of the plurality of grabbing pieces 20, and the plurality of grabbing pieces 20 are folded until the grabbing pieces 20 are closely attached to each other and reset.

In this embodiment, the grabbing unit 22 includes a rotating shaft connected to the grabbing head, and the rotating shaft is used to control the grabbing head to rotate, so as to place the transformer bushings 50 into the transformer bushing 50 trays located in different directions.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
