The working principle of the constant force control device 9d is as follows:
because the mechanical arm is a rigid body, when the polishing executing device contacts with the uneven surface, the pressure on the workpiece is different at different places. When the uniform track path is adopted for polishing, the condition of damaging a polishing tool or a workpiece can occur, so that the polishing path of the joint contact surface needs to be planned in advance. However, if the uneven surface conditions are different among workpieces in a batch, the grinding path of the contact surface cannot be planned in advance.
The constant force control device 9d is specifically an AFD1100-2 type active constant force control device, and is used for solving the above problems and realizing conformal polishing of a surface to be polished. The constant force control device 9d provides a constant contact force between the grinding head 9c and the fork head, and provides a certain amount of buffer stroke for the grinding head 9c, so as to achieve the function of shape following grinding. At the surface relief, the pressure is constant and the relative distance between the grinding head 9c and the output of the industrial robot 9a is much more compressed; in the surface recess, the pressure is constant and the relative distance between the grinding head 9c and the output end of the industrial robot 9a is compressed less.
The working principle of the invention is as follows:
s100, feeding: the working personnel place the sleeve part in the working interval of the sleeve positioning mechanism 6 and place the fork in the working interval of the fork positioning mechanism 7;
s200, fixing the sleeve part through the sleeve positioning mechanism 6: the second pressing mechanism 6d drives the second pressing plate 6c to move to the position right above the sleeve portion and press downwards, the second positioning column 6b penetrates through a through hole in the second pressing plate 6c, the second pressing plate 6c abuts against one end face of the sleeve portion and presses the other end face of the sleeve portion against the first positioning plate 6a, meanwhile, the inner circumferential surface of the sleeve portion abuts against the outer circumferential surface of the second positioning column 6b, and therefore the sleeve positioning mechanism 6 finishes fixing the sleeve portion;
