Spherical workpiece gripper with adjustable range

Abstract

The range-adjustable spherical workpiece gripper comprises a center shaft column and at least three clamping jaws arranged around the center shaft column, the center shaft column is provided with an adjusting seat and a clamping seat, the clamping seat is located below the adjusting seat, the adjusting seat and the clamping seat ascend and descend along the center shaft column, and the adjusting seat is located below the clamping seat. The top of the clamping jaw is hinged to the head end of the first connecting rod, the tail end of the first connecting rod is hinged to the adjusting base, the middle of the clamping jaw is hinged to the head end of the second connecting rod, the tail end of the second connecting rod is hinged to the center shaft column, and the clamping base is connected with the second connecting rod through the third connecting rod. And when the clamping seat ascends and descends, the clamping jaws are folded or unfolded. The angle of the clamping jaw can be adjusted according to the size of a workpiece, proper clamping force can be obtained more easily, and the workpiece is prevented from being damaged.

Description

Technical field [0001] The present invention relates to a workpiece gripper, in particular to a spherical workpiece gripper with an adjustable range. Background [0002] In the field of industrial automation, a robotic hand is often used to achieve grasping action. Traditional manipulators are used in the grasping of general workpieces, usually using three-jaw grippers to grasp from the three directions of the spherical circle, or by clamping left and right and setting a cavity on the opposite side of the clip to clamp the spherical workpiece. These mechanical grippers are not easy to adjust because the angle of the grippers is not easy to adjust, so in order to meet the stable grasp of different sizes of workpieces, the manipulator needs to set a larger gripping force, which is easy to cause damage to the workpiece. For some precision workpieces using flexible manipulators, the structure is more complex, the processing and production costs are higher, the difficulty of installat...

AI Technical Summary

Problems solved by technology

These mechanical grippers are not easy to adjust the angle of the jaws, so in order to meet the stable grasping of workpieces of different sizes, at the same time, the manipulator needs to set a large grasping force, which is easy to cause damage to the workpiece

The flexible manipulator used for some precision workpieces has a complex structure, high processing and production costs, and high difficulty in installation and maintenance. More importantly, it can only be used for specific models and sizes of workpieces, and its use is limited.
