Invariable frictional force polishing controlling means

The utility model relates to an invariable frictional force polishing controlling means, including controller, polishing subtotal work piece clamping part, the polishing part includes horizontal dead axle, burnishing device and a servo motor, and a servo motor drive burnishing device move on horizontal dead axle, work piece clamping part includes riser and mounting panel, and orientation plane reciprocating motion is to the relative riser of mounting panel, is provided with a plurality of compression spring between mounting panel and the riser, and the mounting panel is provided with anchor clamps on burnishing device's terminal surface, the riser is installed apart from the inductor on the terminal surface of mounting panel one side, the controller answers the vessel shape to become electric connection with a servo motor and feeling of distance respectively. Utilize spring compression to be out of shape the characteristic that is directly proportional with elasticity, through the distance of distance sensor real -time detection with the mounting panel, control burnishing device through the controller and transversely deciding the epaxial volume of shifting out, realize guaranteeing that the work piece receives the purpose of stationary extrusion power.
