Rotatable mechanical gripper device

Abstract

The invention provides a rotatable mechanical gripper device, and belongs to the technical field of mechanical grippers. The technical problem that an existing pneumatic gripper device cannot achievethe effect that two grippers are switched in the horizontal plane is solved. The rotatable mechanical gripper device comprises a machine frame, a rotation air cylinder and two mechanical grippers, wherein the machine frame is horizontally arranged; an output shaft of the rotation air cylinder is fixedly connected with the middle of the machine frame; the two mechanical grippers are movably connected with the two ends of the machine frame, are coaxially arranged and can clamp and place workpieces; the rotation air cylinder can drive the machine frame to horizontally rotate within the preset angle, and the two mechanical grippers can synchronously move along with rotation of the machine frame; and the two mechanical grippers are simultaneously installed on the horizontally-arranged machine frame, the machine frame is driven to rotate through the rotation air cylinder, then, switching of the two mechanical grippers in the horizontal direction can be achieved, and accordingly, workpieces can be rotated in the horizontal direction.

Description

technical field [0001] The invention belongs to the technical field of mechanical grippers, and relates to a rotatable mechanical gripper device. Background technique [0002] Manipulator claws are commonly used mechanical parts in machining equipment at present, especially for the processing of shaft workpieces. Generally, different manipulator claws need to be designed according to different processing techniques and processing requirements. For the processing of shaft workpieces, common manipulators The jaw is a two-jaw pneumatic jaw structure. [0003] For example, the invention patent with application number 201710639935.8 discloses a swing-type rotary air claw device, and the invention patent with application number 201710647581.1 discloses a manipulator rotary air claw device. Swing in the plane, the mechanical rotating gripper device can realize the swing of the two air grippers in the three-dimensional space, but these two kinds of air gripper devices can only real...

Problems solved by technology

[0003] For example, the invention patent with application number 201710639935.8 discloses a swing-type rotary air claw device, and the invention patent with application number 201710647581.1 discloses a manipulator rotary air claw device. Swing in the plane, the mechanical rotating gripper device can realize the swing of the two air grippers in the three-dimensional space, but these two kinds of air gripper devices can only realize the exchange of the two grippers in the vertical and horizontal directions, that is, the vertical workpiece and the horizontal The replacement of workpieces cannot realize the replacement of the two claws in the horizontal direction. When the existing processing equipment needs the workpiece to be replaced in the horizontal direction, the air gripper devices of the above two structures cannot realize this function; in addition, when the workpiece is heavy And when two claws are required to be clamped at the same time, the above two structures cannot clamp the workpiece at the same time
