Abstract

DC60 (24/09/41) Inner sander for the inner surface of annular workpieces and which It consists of a driven pivot (16) which holds the tool holder (18), a clamping device (14) for the workpiece (15) to be trimmed. And a feeder device (10,11) for relative motion Between the workpiece and the motor tool (17) located in the recess (7a) in the spindle (7), it is placed in a cylindrical tubular housing (3) with a slit section. The inner space of the cylinder in the longitudinal way, where this gap will have Its longitudinal axis Is in an indentation manner overlapping from The axis of the housing in the length The spindle can Movable angular in the gap, the case (3) is enclosed by the jacket. The rotatable exterior (5), which is firmly connected to the cover part (19), the gripping device (14), and the cover part (19) arranged to hold the part. The task (15) to be performed and causes it to rotate simultaneously with the cover piece (19) around its axis, this spindle (17), when it is directed to move in the gap section as Said will produce results in Drive the tool body (18) in the corresponding path. Let the tool surface move towards and Touch of the circle The inside of the workpiece that is clamped by the chuck An inner sander for the inner surface of an annular workpiece and consisting of a driven dowel (16), which is mounted on the tool (18). (14) for clamping the workpiece (15) to be trimmed And a feeder (10,11) for producing relative feeder motion. Between workpiece and tool It is characterized in such a way that the motor (17) is located in the niche (7a) in the spindle (7), which is arranged in the cylindrical tubular housing (3) with The gap inside the cylinder in the line. Long, where the inner cavity of this cylinder has Its longitudinal axis is in an indentation that distances from The longitudinal axis of the case and the spindle can In such a gap, the housing (3) is enclosed by a rotatable outer casing (5), which is firmly connected to the cover element (19). A gripping device (14) and a cover part (19) are set aside to hold the workpiece (15) to be processed and cause it to rotate together with the lid piece. Closed (19) around its axis, such spindle (7), when directed to move angular in the gap, as As mentioned, this will result in driving the pivot pin (16) together with the tool (18) in the line of the made path. Let the surface of the tool approach and come in contact with the circle. The inside of the workpiece that is clamped by the chuck
