Manipulator tongs capable of striding across fixed obstacle

Abstract

The invention provides manipulator tongs capable of striding across a fixed obstacle. The manipulator tongs capable of striding across the fixed obstacle comprise a tong rack, a steering machine, a first gear, a second gear, left tongs and right tongs, wherein the steering machine is fixed to the tong rack; the first gear is fixed to the tong rack, and the output end of the steering machine is connected with the first gear though a steering plate; the second gear is fixed to the tong rack, and the first gear and the second gear are engaged with each other; the left tongs comprise multiple left fingers connected in parallel, and are connected with the first gear through the uppermost left finger; the right tongs comprise multiple right fingers connected in parallel, and are connected with the second gear through the uppermost right finger. According to the manipulator tongs capable of striding across the fixed obstacle, the structure can be disassembled freely, the structure is simple, and object clamping across the fixed obstacle on a rough ground is achieved, the clamping is stable, the benefit is improved, and the comprehensive benefit is high.

Description

technical field [0001] The invention relates to the field of clamp-type mechanical grippers, in particular to a mechanical gripper capable of crossing fixed obstacles. Background technique [0002] There are many types of clamp-type mechanical grippers, most of which are rotary hands. The lever transmission mechanism is used to change the transmission ratio and the direction of motion; the other is the translational hand, which realizes the opening or closing action through the reciprocating motion or plane movement of the finger surface. [0003] Through analysis, it is found that the structure of the second mechanical gripper with translation mechanism is complicated, and it is not as widely used as the first type of rotary mechanical gripper. However, both gripper structures have disadvantages. For obstacles on rough ground, the gripper cannot go around the obstacle to grab the object. At this time, the gripper is blocked by the obstacle and the grip will fail. Therefor...
