Please refer to fig. 1 to 4:
the utility model provides an industrial robot's gripper jaw, including gripper jaw 1, pneumatic cylinder 2, grip block 8, each part to an industrial robot's gripper jaw carries out detailed description below:
the bottom of the clamping claw 1 is provided with a clamping groove 101, the clamping groove 101 can conveniently clamp a cylindrical workpiece, and because two side surfaces of the clamping groove 101 are inclined surfaces, when the clamping groove 101 clamps the cylindrical workpiece with a larger diameter, the clamping plate 8 cannot meet the clamping and positioning requirements on the workpiece, so that the two side surfaces of the clamping groove 101 can be tangent to the outer surface of the cylindrical workpiece with a larger diameter, the clamping and positioning of the workpiece can be assisted, and for the cylindrical workpiece with a smaller diameter, the clamping plate 8 can smoothly assist in positioning the cylindrical workpiece;
the hydraulic cylinder 2 is embedded at the left end and the right end of the clamping claw 1 and is positioned at the left side and the right side of the clamping groove 101, the piston rod 3 is connected inside the hydraulic cylinder 2 in a sliding mode, the tail end of the piston rod 3 is rotatably connected with the clamping roller 4, and one end of the clamping roller 4 is fixedly connected with the motor 11;
specifically, the motor 11 can drive the clamping rollers 4 to rotate, so that when the clamping claw 1 clamps a workpiece, the clamping rollers 4 can rotate on the surface of the workpiece, the workpiece moves towards the upper end of the clamping groove 101 under the pushing of the two clamping rollers 4, and meanwhile, when the clamping rollers 4 push the workpiece, the hydraulic cylinder 2 pushes the piston rod 3 to extend through oil pressure, so that the distance between the two clamping rollers 4 can be slowly reduced, and the workpiece clamped in the clamping groove 101 can be prevented from falling;
a pressure sensor 5 is embedded in the top surface inside the hydraulic cylinder 2, and a hydraulic oil pipe 9 is fixedly connected to one side surface of the hydraulic cylinder 2; specifically, the pressure sensor 5 can monitor the oil pressure inside the hydraulic cylinder 2, convert the oil pressure information into an electric signal and send the electric signal to the controller of the industrial robot, when the oil pressure inside the hydraulic cylinder 2 is in a stable state, the piston rod 3 is in a normal extension state, when the oil pressure inside the hydraulic cylinder 2 is suddenly increased, the extension of the piston rod 3 is blocked, the oil pressure inside the piston rod 3 is increased, and when the extension of the piston rod 3 is blocked, the workpiece is clamped in place, successfully fixed in the clamping groove 101 and cannot move upwards continuously, and at this time, the industrial robot can stop sending oil to the hydraulic cylinder 2, so as to complete clamping of the workpiece;
when the cylindrical workpiece needs to be unloaded from the clamping claw 1, the hydraulic oil in the hydraulic cylinder 2 is only required to be sent back to the hydraulic oil tank through the hydraulic oil pipe 9, so that the piston rod 3 on the hydraulic cylinder 2 can be retracted into the hydraulic cylinder 2, and the workpiece can fall from the clamping groove 101 after being clamped by the piston rod 3 and the clamping roller 4;
the clamping plate 8 is positioned at the upper end inside the clamping groove 101, and the bottom surface of the clamping plate 8 is rotatably connected with a rubber roller 10; specifically, the clamping plate 8 can perform auxiliary positioning clamping on the cylindrical workpiece, so that the cylindrical workpiece is ensured not to shake in the clamping groove 101, and the rubber roller 10 can enable the clamping plate 8 and the cylindrical workpiece to rotate relatively, so that the clamping roller 4 can conveniently clamp the workpiece;
the upper surface of the clamping plate 8 is fixedly connected with a telescopic rod 6, the bottom end of the telescopic rod 6 is sleeved with a spring 7, and the top of the telescopic rod 6 is welded on the top surface of the clamping groove 101; specifically, through the cooperation of the telescopic rod 6 and the spring 7, the telescopic rod 8 can clamp and position cylindrical workpieces with different diameters.
The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which may be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
