Posture-controllable bending and twisting coupling flexible clamping jaw

Abstract

The invention discloses a posture-controllable bending and twisting coupling flexible clamping jaw, and belongs to the technical field of mechanical clamps. The flexible clamping jaw comprises an adapter seat and is characterized in that two flexible clamping jaw assemblies are symmetrically arranged at the lower part of the adapter seat, each flexible clamping jaw assembly comprises a flexible finger assembly and a posture adjusting assembly, and each flexible finger assembly comprises a bending and twisting coupling flexible finger and further comprises a first rigid seat and a second rigidseat which are matched and fixedly connected with the bending and twisting coupling flexible finger. According to the flexible clamping jaw, through labyrinth type air chambers which are symmetricallyand obliquely arranged left and right, the planes on the inner sides of clamping jaw bodies form bent and changed V-shaped included angles through different air inflow, stable grabbing of objects, especially grabbing of objects with complex curved surfaces, is facilitated, and the bending and twisting coupling flexible clamping jaw can also effectively prevent target objects from being damaged; and through the arrangement of an angle posture adjusting mechanism in the vertical direction and a position regulation and control mechanism in the horizontal direction, target objects with differentsizes and different curved surface shapes can be better matched and grabbed.

Description

technical field [0001] The invention belongs to the technical field of mechanical clamps, and in particular relates to a bending-torsion coupling flexible clamping jaw with controllable posture. Background technique [0002] In the automatic production line, the end of the traditional mechanical arm or other external equipment mostly use rigid grippers to cooperate with the gripping objects, which is suitable for objects with regular shapes and easy rigid gripping, but for some irregular objects or objects that cannot be rigidly gripped , it cannot be grasped; although flexible grippers are also used in the existing technology, when facing some complex curved surfaces and objects of different sizes, it is necessary to use multiple fingers (not less than 3 fingers) or replace larger models. Gripper gripping, the gripping structure is complex, and when faced with a gripping environment in a narrow space, it cannot accommodate multiple fingers and cannot meet the gripping requi...
