[0002] A centerless grinder is a type of grinder that does not require the axis of the workpiece to be positioned for grinding. It is mainly composed of three mechanisms: a grinding wheel, an adjusting wheel, and a workpiece holder. The grinding wheel is actually responsible for grinding, the adjusting wheel controls the rotation of the workpiece and the feed speed of the workpiece, and the workpiece holder supports the workpiece during grinding. These three parts can be coordinated in several ways, but the principles are the same except for stopping grinding.

[0003] The existing manipulator grippers on centerless grinders have certain shortcomings when in use. They are not stable enough when grabbing and unloading goods, and the speed is relatively slow, which is time-consuming and labor-intensive, reduces the efficiency of cargo loading and unloading, and affects use. To address the above problems, we proposed an improvement and upgrade of a manipulator gripper for automatic grabbing and unloading of centerless grinders and lathes. Utility Model Content
