Grabbing mechanism for special-shaped workpiece

Abstract

The invention discloses a grabbing mechanism for a special-shaped workpiece. The grabbing mechanism comprises a working support (1), a driving air cylinder (2) is arranged on the top face of the working support (1), a piston rod of the driving air cylinder (2) penetrates the working support (1) to be connected with a first lifting plate (12), a second lifting plate (23) is connected to the lower portion of the first lifting plate (12) through a connecting column (22), and a first sucking device (3) and a second sucking device (32) are symmetrically arranged on the bottom face of the first lifting plate (12). The grabbing mechanism has the characteristic that the workpiece is not prone to being damaged, the adsorption stability and firmness of absorption of the special-shaped workpiece arebetter, and the workpiece is not prone to falling.

Description

technical field [0001] The invention relates to a gripping mechanism for workpieces, in particular to a gripping mechanism for special-shaped workpieces. Background technique [0002] In the manufacturing process of metal workpieces, it is often necessary to transfer the workpiece from one operating platform to another for another operation, and in this process, the grabbing mechanism plays an important role, and the grabbing mechanism is used to move the workpiece Grab from one operating platform, then switch positions, and put the workpiece into another operating platform. For some workpieces, especially precision workpieces, if the claw structure is used to grab the workpiece, it is easy to damage the workpiece. If the suction structure is used to grab, for some special-shaped workpieces, especially uneven or stepped workpieces , The suction cup cannot be completely and evenly adsorbed on the surface of the workpiece, and there is a gap between the suction cup and the wo...

Problems solved by technology

For some workpieces, especially precision workpieces, if the claw structure is used to grab the workpiece, it is easy to damage the workpiece. If the suction structure is used to grab, for some special-shaped workpieces, especially uneven or stepped workpieces , the suction cup cannot be completely and evenly adsorbed on the surface of the workpiece, and a gap is easily formed between the suction cup and the workpiece, resulting in unsatisfactory adsorption stability and firmness, and the workpiece is easy to fall

Therefore, the grasping mechanism of the existing claw structure has the problem that the workpiece is easily damaged, and the grasping mechanism of the existing suction structure has the problem that the adsorption stability and firmness of the special-shaped workpiece are not ideal, and the workpiece is easy to drop.
