The four-jaw mechanism is also applied to more occasions, such as the four-jaw chuck, the electric four-jaw assembly O-ring, the four-jaw pneumatic finger, etc. The linkage mechanism, also known as the low pair mechanism, is a type of mechanical component. Refers to a mechanism composed of several (more than two) components with definite relative motion connected by a low pair (rotating pair or moving pair). In the four-claw mechanism, a link mechanism is used to control the opening and closing of the claws. However, the existing The four-claw mechanism generally grabs the bag from the top of the bag. If the bag is to be opened, the link mechanism will block the opening of the bag. It is difficult to meet the requirements of bag opening and feeding, and the existing four-claw mechanism also has the disadvantages of large volume, high cost and low efficiency

The invention discloses a novel four-jaw mechanism. The novel four-jaw mechanism comprises a driving device, a mounting plate, a connecting piece, an upper cover plate, a lower cover plate, an upper-layer connecting rod assembly, a lower-layer connecting rod assembly, an outer claw finger and an inner claw finger, wherein the driving device is fixed on the rear side of the mounting plate, after the power output end of the driving device penetrates through the mounting plate, the power output end of the driving device is connected with the connecting piece located on the front side of the mounting plate; the upper connecting rod assembly comprises a pair of first upper connecting rods, a pair of second upper connecting rods, a pair of third upper connecting rods and a pair of fourth upper connecting rods; the lower-layer connecting rod assembly comprises a pair of first lower connecting rods, a pair of second lower connecting rods, a pair of third lower connecting rods and a pair of fourth lower connecting rods. The four-jaw mechanism is compact in structure and achieves the functions of unfolding, folding and self-centering of a designated position, and is particularly suitable forbag opening and bagging.
Description
technical field [0001] The invention relates to the technical field of mechanical claws, in particular to a novel four-claw mechanism. Background technique [0002] At present, with the higher and higher requirements for work efficiency, automation is generally widely used. The four-jaw mechanism is also applied to more occasions, such as the four-jaw chuck, the electric four-jaw assembly O-ring, the four-jaw pneumatic finger, etc. The linkage mechanism, also known as the low pair mechanism, is a type of mechanical component. Refers to a mechanism composed of several (more than two) components with definite relative motion connected by a low pair (rotating pair or moving pair). In the four-claw mechanism, a link mechanism is used to control the opening and closing of the claws. However, the existing The four-claw mechanism generally grabs the bag from the top of the bag. If the bag is to be opened, the link mechanism will block the opening of the bag. It is difficult to me...
