Further, described yaw case is connected by key with the oilstone cutter.
The utility model bedstead is T type support, A-frame preferably.
Technical conceive of the present utility model:
The orientation problem of workpiece: the finished surface of workpiece is a circular arc anchor ring, it is static that the rotatablely moving of workpiece can be regarded workpiece as, the circular motion of oilstone cutter, its circumference running orbit and circular arc anchor ring have the axiality requirement, its allowance is little, the benchmark of can doing for oneself is a benchmark with bearing inner ring raceway axis; On axial location, be benchmark with the end face of bearing.Thereby the targeting scheme that provides as shown in Figure 1, three positioning supports points (the abbreviation strong point) are set in the horizontal direction, wherein two places are fixed support, one place is an adjustable supports, concrete setting element is a nail of bulb, two fixed supports radially be against finished surface (circular arc anchor ring), regulate adjustable supports make three support fully near with finished surface, and it can be slided on the circular arc anchor ring, promptly three strong points rotate around bearing axis, obviously above-mentioned three strong points determine to justify and the circular arc anchor ring coaxial, the realization self-centering, reach overlapping of location benchmark and operation benchmark, three strong points limit simultaneously
Two frees degree; On axis direction, at the bearing upper surface three strong points are set, concrete setting element is a gripper shoe, realize workpiece spindle to the location, restriction
Three degree of freedom.Limit 5 frees degree altogether, realize the location of workpiece in lathe.
Finish the processing of super lappingout, must realize rotatablely moving of the swing of the relative workpiece of cutter (oilstone cutter) and lathe relative with workpiece.The main motion of super lappingout is the oilstone cutter perpendicular to the double vibrations motion according to certain rules of workpiece direction of rotation, the utility model is installed in the yaw motor on the lathe bed, by the yaw case on the belt transmission driving lathe bed, the yaw case is directly realized the swing of oilstone with it.The feed motion of super lappingout is workpiece speed rotation in accordance with regulations, the utility model fixation workpiece, allow yaw case and the oilstone cutter serve as that axle is rotated with the axis of bearing, consider that processing is to workpiece the less demanding of speed that rotatablely move, so adopt workman's manipulator body to make yaw case mounted thereto and oilstone cutter and workpiece (bearing inner ring) relative rotary motion, safe, energy-conservation, simple in structure, need not transmission.
The course of work of the present utility model:
Workpiece is fixed in workbench, lathe is placed on the workpiece, make three axial gripper shoes be against the bearing upper surface, realize axial location, make two fixed support nails radially be against finished surface, regulate adjustable supports nail radially, make three nails be supported in workpiece with certain pretightning force, realize centering, regulate the oilstone tool position and make it gently be against work surface; Open auxiliary coolant system; Open the yaw motor, the oilstone cutter is applied authorized pressure, make its flexible being pressed on the finished surface, the workman slowly pushes away described hand-pushing handle, drives the relative workpiece rotation of lathe, surpasses lappingout processing, carries out at least one week, finishes processing; Close coolant system, remove the oilstone cutter, close the yaw motor, unload lathe, take out workpiece.
The beneficial effects of the utility model are: general structure design compactness, simple, and accurate work piece positioning, convenience, easy to use, production cost is low.
