Description

Technical Field

[0001] This utility model belongs to the field of screw feeding technology, and in particular relates to a screw feeding mechanical gripper with a buffer function. Background Technology

[0002] In modern industrial production, screw assembly is an extremely common operation. Traditional screw feeding methods often rely on manual operation, which is inefficient.

[0003] Therefore, people's demand for mechanical feeding is increasing. Among them, mechanical grippers are a good feeding device. However, when existing mechanical grippers grab screws, they are prone to inertial impact during the gripping process, which can damage the screws. This not only greatly reduces the quality of the screws, but also easily causes the mechanical gripper connection to loosen. To address this, we have proposed a screw feeding mechanical gripper with a buffer function. Utility Model Content

[0004] The purpose of this utility model is to provide a screw-feeding mechanical gripper with a buffer function. Specifically, the mechanical claw contacts the screw, applies force to the screw, and the screw also transmits force to the mechanical claw. The mechanical claw then transmits the force to a hinge frame, which in turn transmits it to a connecting rod, which in turn transmits it to a connecting rod. A spring and a damper work together to reduce the collision force between the mechanical claw and the screw, thereby reducing damage to the screw. This solves the problem of existing mechanical grippers easily generating inertial impacts during screw handling, which damages the screw, significantly reducing its quality and causing loosening at the gripper's connection points.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a screw feeding mechanical gripper with a buffer function, comprising an electric push rod and two rotating plates. The bottom output rod of the electric push rod is fixedly connected to a housing, and also includes:

[0009] Furthermore, the gripping assembly includes a mechanical claw installed inside the rotating plate. A plurality of claw teeth are fixedly connected to the bottom of the mechanical claw, and two hinge frames are fixedly connected to opposite sides of the two mechanical claws.

A damper is contacted at the top of the spring seat, and a connecting rod three is slidably connected inside the damper. A connecting rod two is hinged to the bottom of the connecting rod three, and the outer surface of the bottom of the connecting rod two is hinged to the inside of the hinge frame one. A spring is contacted at the top of the connecting rod three, and the top of the spring is fixedly connected to the inner side of the top of the spring seat.

[0010] Furthermore, the control component includes a long plate installed inside the housing, and a second hinge is fixedly connected to one side of each of the two rotating plates. A first connecting rod is hinged inside the second hinge. The long plate is T-shaped. The movement of the first connecting rod drives the second hinge to move, and the second hinge drives the rotating plates to move.
