Embodiment Construction

[0013] Such as figure 1 As shown, the universal gripper using magnetorheological plastics includes a U-shaped support frame 2 with a steel magnetic permeable frame as a structural support, and a coil 1 wound in the middle of the U-shaped support frame 2 to generate a magnetic field. An aluminum non-magnetic partition 5 straddling the middle of the U-shaped support frame 2, and a partition 3 between the partition 5 and the U-shaped support frame 2, which can concentrate the magnetic field generated by the coil at both ends below the magnetic permeable frame , while placing the rechargeable battery and the control circuit in the middle of the compartment 3. The outermost is a rubber sleeve 6 with certain elasticity and surface roughness, and the high-performance magnetorheological plastic body 4 is wrapped in it.

[0014] When the gripper grasps the article, first the gripper is pressed into the object to be grasped by contacting the article 7 . join figure 2 , the number 7 ...

Abstract

The invention relates to an universal gripper using a magneto-rheological plastic body. The universal gripper comprises a U-shaped supporting frame, a coil, a partitioning plate and a partitioning layer, wherein the coil is wound at the middle part of the supporting frame; the partitioning plate is arranged at the middle part of the supporting frame; the partitioning layer is formed among the partitioning plate, the coil and the U-shaped supporting frame; a charging battery and a current control circuit are placed in the partitioning layer; a rubber jacket is tightly coated outside; the high-performance magneto-rheological plastic body is filled between the U-shaped bracket and the rubber jacket. The universal gripper has the advantages that the gripping force can be adjusted; the shape of the gripper can be changed to enable the gripper to be better attached to the surface of an object; in addition, the whole structure is simple and the manufacturing cost is lower.

Description

technical field [0001] The invention relates to a universal gripper using a magneto-rheological plastic body. Specifically, a universal gripper with simple structure, adjustable gripping force and variable gripping shape has been developed. Background technique [0002] The gripper is an essential part in mechanized and automated production, human bionics, robot manufacturing technology and other fields. [0003] Magnetorheological plastic is a new type of magnetorheological adhesive. The difference from traditional magnetorheological adhesives is that magnetorheological plastic has strong plasticity, that is, it can easily change its shape and maintain it at room temperature. Magnetorheological plastics have good mechanical properties, and their magnetorheological effect can reach 800%. The softness and hardness of magnetorheological plastics can be adjusted by adjusting the current. At the same time, the magnetostrictive effect of the magnetorheological plastic can make i...
