Description

Technical Field

[0001] The utility model relates to the technical field of insulator production, in particular to a clamp for grabbing insulators. Background Art

[0002] Insulators are devices installed between conductors at different potentials, or between a conductor and a grounded structure, capable of withstanding voltage and mechanical stress. Insulators come in a wide variety of types and shapes. While their structures and appearances vary significantly, they all consist of two main components: the insulating element and the connecting hardware. Composite insulators are currently the most commonly used. During production, composite insulators are gripped by a fixture on a robotic arm and then placed in the desired location.

[0003] Currently, the grippers on robotic arms can only grasp insulators of one length. To grasp insulators of a different length, they must be disassembled and reassembled with the corresponding gripper. Consequently, a single gripper cannot grasp insulators of multiple lengths. Therefore, there is an urgent need to design an insulator grasping gripper to address this issue. Utility Model Content

A clamp is fixed to the outer wall of one side of the gear, and a circular arc opening is provided on one side of the bottom of the two clamps. A double-sided rack is provided inside the shell, and the double-sided rack is engaged with the two gears, and the double-sided rack is located between the two gears.
