Precise pneumatic clamping mechanical gripper for thin plate type workpiece

Abstract

The invention relates to a precise pneumatic clamping mechanical gripper for a thin plate type workpiece. The precise pneumatic clamping mechanical gripper comprises a gripper clamping mechanism, a gripper moving mechanism and an explorator moving mechanism, wherein the gripper clamping mechanism comprises a pair of plate-shaped claws in up-down correspondence, a pair of explorators in left-right correspondence and a positioning mechanism; the gripper moving mechanism comprises a sliding bottom plate and a pair of inner guide tracks; the explorator moving mechanism comprises a U-shaped frame, an air cylinder and a pair of outer guide tracks; the air cylinder is used for driving the pair of explorators to move in a reciprocating manner through the U-shaped frame, and used for controlling the pair of plate-shaped claws to clamp and release in the movement process; meanwhile the pair of claws is moved in a reciprocating manner along the pair of inner guide tracks through the sliding bottom plate. The precise pneumatic clamping mechanical gripper is reasonable in structural design, and all types of action such as overall movement of the mechanical gripper and clamping and release of upper and lower clamping plates of the mechanical gripper can be achieved through the one air cylinder.

Description

technical field [0001] The invention relates to the field of precision machinery, and relates to a pneumatic clamping device. Background technique [0002] In the field of mechanical engineering, grippers are commonly used in the clamping scheme of thin-plate workpieces, such as various pneumatic grippers, with a general accuracy of 0.03 to 0.05mm. On the production line higher than 0.01mm, it is difficult to ensure the positioning accuracy requirements of the workpiece only by using ordinary pneumatic grippers to clamp the workpiece, which often requires a more complicated positioning and clamping mechanism to complete. Contents of the invention [0003] The purpose of the present invention is to provide a pneumatic clamping gripper with high repeat positioning accuracy, compact structure, high efficiency and quickness, so as to meet the requirements of high-precision and fast clamping of thin plate workpieces, and the precision can reach 0.01 to 0.02mm.
