Abstract

The invention discloses a thumb type grabbing mechanism. The thumb type grabbing mechanism comprises a base, thumb assemblies, a rotating power piece used for driving the thumb assemblies to rotate and a bending power piece used for pulling the thumb assemblies to bend the thumb assemblies, a center shaft is arranged on the base, and the rotating power piece is arranged on the center shaft in a rotatable mode; two groups of the thumb assemblies are provided, are symmetrically installed on the rotating power piece, and are driven by the rotating power piece to rotate synchronously; the bendingpower piece is installed on the center shaft, and synchronously rotates along with the rotating power piece; and the bending power piece is used for driving the thumb assemblies to complete the bending action. According to the thumb type grabbing mechanism, the thumb action principle of the human is simulated, the rotating power piece is arranged on the center shaft and is used for driving the thumb assemblies to rotate, the bending power piece is arranged on the center shaft and is used for driving the thumb assemblies to be bent, so that the requirement for rotating and grabbing action in afixed direction is met.

Description

technical field [0001] The invention relates to a thumb-type grasping mechanism, which belongs to the technical field of mechanical structures. Background technique [0002] In the automatic production line, when some small parts with irregular shapes and large blank errors are grasped by special mechanisms, in order to change the conveying direction, sometimes it is necessary to rotate in a fixed direction. Changes, especially when rotating after clamping, rigid clamping often leads to unreliable clamping, and it is necessary to increase the clamping force and clamping point, which causes the problem of complex and huge grabbing mechanism structure and increased electromechanical costs. The use of robot rotation has greatly increased the cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a thumb-type grasping mechanism to solve the problem of unstable clamping r...
