Abstract

The invention discloses a mechanical grabbing device for an industrial robot, and belongs to the technical field of robot end equipment. The mechanical grabbing device for the industrial robot comprises a mounting box, a bidirectional wire cylinder, two sets of screw rods, clamping jaws, a telescopic rod, a hydraulic rod and a driving part, and the bidirectional wire cylinder is rotationally connected to the mounting box; the screw rows are in threaded connection with the bidirectional wire cylinder, and the screw directions of threads on the two screw rods are opposite; the clamping jaws are fixedly connected to the output ends of the screw rods; the two ends of the telescopic rod are rotationally connected to the side wall of the mounting box and the tops of the clamping jaws correspondingly; the two ends of the hydraulic rod are rotationally connected to the telescopic rod and the mounting box correspondingly; and the driving part is arranged in the mounting box and is used for driving the bidirectional wire cylinder to rotate. The hydraulic rod, the telescopic rod and the mounting box are used for forming a deformable triangle, then hydraulic oil is used for providing supporting force, the gravity borne by the screw rods is dispersed, then the bearing capacity of the grabbing device is improved, and the service life of the mechanical grabbing device is prolonged.

Description

technical field [0001] The invention relates to the technical field of robot terminal equipment, in particular to a mechanical grabbing device for industrial robots. Background technique [0002] With the development of science and technology, the application of robots has become more and more extensive. Now some dangerous or simple repetitive tasks are replaced by robots one after another. When the robot transports the items, it needs to use the grabbing device to hold the items. [0003] In the prior art, when the screw-type grabbing device is clamping heavy objects, the screw is prone to deformation under the gravity of the heavy object, resulting in damage to the grabbing device, which in turn leads to grabbing failures and delays in work. In order to improve the screw-type grabbing In order to improve the service life and load-bearing capacity of the device, it is necessary to design a mechanical grabbing device for industrial robots. Contents of the invention [000...
