Mechanical hand grab based on model airplane helicopter

Abstract

The invention provides a mechanical hand grab based on a model airplane helicopter. When an object is grabbed, a control motor rotate a certain angle, the motor drives power rods to rotate to a certain position, the power rods on two sides are connected through a synchronous rod, the two power rods press a movable rod simultaneously, and a movable ring rolls on the slopes of the power rods. Meanwhile, the movable ring rotates around a motor shaft, a clamp frame rotates further, the lower end of the clamp frame is stretched, an elastic pull rope is lengthened in a pulled mode, when the helicopter enables the mechanical hand grab to move to a special position, and the control motor rotates continuously. At this moment, the movable ring rotates out of the slopes of the power rods to be separated from the power rods, and by means of action of the elastic pull rope, the clamp frame clamps the object rapidly. When the clamp frame is closed completely, one side of the clamp frame cannot rotate across the middle because of action of a stopping rod, when the object needs placing down, the control motor rotates back, a gap enabling the power rods to rotate back is formed on a I-shaped frame, the power rods can rotate a circle to rotate back to a starting point, and the procedure that the clamp frame is opened before the object is grabbed is repeated.

Description

technical field [0001] The invention provides a mechanical gripper, in particular provides a mechanical gripper based on a model airplane helicopter, so as to realize the grasping of ground objects. Background technique [0002] At present, with the large-scale rise of aircraft model sports and the gradual popularization of various industrial robots, the application of mechanical grippers is becoming more and more extensive. It is used to operate machines or be used for object handling, grasping, etc. In aircraft model sports, mechanical grippers Most of them are used to grab ground objects. At present, most of the more mature applications use mechanical clamping, but most of them have a slow clamping speed. Because the airflow of the model helicopter is unstable when it is close to the ground, the helicopter shakes a lot, and it is difficult to hold the object for a long time. It is just placed in the middle of the mechanical gripper, which reduces the success rate of grabb...
