Gripper structure of truss manipulator

Abstract

The invention discloses a gripper structure of a truss manipulator. The structure comprises a base, wherein two claw arms are coupled to the base; the claw arms are driven by an oil cylinder; a through groove is arranged in each claw arm; an elastic connecting rod is movably connected in each through groove; each elastic connecting rod is connected to a clamping disc; each clamping disc comprisesa disc body; a mounting groove is arranged in the surface of each disc body; a first chute is arranged in the side wall of each mounting groove; a positioning pin is arranged at the bottom end of eachfirst chute; a supporting rod is arranged in each mounting groove; two ends of each supporting rod are slidably inserted into the corresponding first chute; a plurality of clamping blocks are radially arranged on each supporting rod; positioning holes in one-to-one correspondence with the clamping blocks are arranged at the two ends of each supporting rod; a connecting line of each clamping blockand the corresponding positioning hole is parallel to the axis of the corresponding supporting rod; and the positioning pins and the positioning holes are alternatively matched. According to the structure, the defects of the prior art can be improved, and the clamping stability of a workpiece is ensured on the basis of adopting a two-claw structure.

Description

technical field [0001] The invention relates to the technical field of truss manipulators, in particular to a truss manipulator claw structure. Background technique [0002] A truss robot is an industrial device with a frame structure that can move in three-dimensional space. It has the advantages of high positioning accuracy, heavy load and simple structure, and is widely used in various automatic production sites. For the gripper of the truss manipulator for clamping special-shaped workpieces, it is usually designed with a structure of three or more claws to ensure clamping stability, and each claw arm needs to be equipped with a set of driving devices and control programs. The cost of the multi-claw manipulator is higher. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a truss manipulator claw structure, which can solve the deficiencies of the prior art, and ensure the clamping stability of the workpiece on ...
