Abstract
A groove boring cutter utilizes the movement of a cutter arbor in a hole that forms an angle with a rotation axis to realize radial feed and process a groove in the hole of a part. A boring cutter is fixed in a round hole at the front end of a retractable cutter arbor; one end surface of an adjusting screw is propped against the boring cutter; the retractable cutter arbor is mounted on an inclined hole of a cutter body; a pin is mounted in a hole which is positioned on the retractable cutter arbor and perpendicular to the axis of the cutter body, and corresponding holes on a sliding sleeve respectively; the sliding sleeve is mounted on a column at the large end of the cutter body; an outer sleeve is mounted on the sliding sleeve through two deep-groove ball bearings, a thrust ball bearing and a retaining pad; a positioning sleeve is mounted in an inner hole on the front edge of the outer sleeve through threads and fixed through lock nuts; a guide pole is propped against the rear end of the retractable cutter arbor; a plug is mounted in a screw hole at the rear end of the cutter body; and a spring is mounted between the guide pole and the plug. The groove boring cutter can be used to conveniently and quickly bore the groove with a certain width in the inner hole of the part.

Technical field
The utility model relates to metal cutting tool, the especially boring tool of machine components processing.
Background technology
The groove that needs processing is arranged, as circlip for hole groove, O type ring recess in the endoporus of some box parts in machine-building.Incompatibility is processed on lathe.On boring machine, add man-hour, require boring cutter that the function of radial feed is arranged.Some boring machines do not have this mechanism, even if the boring machine that has has depth-feed mechanism, mechanism changes cumbersome, the production in enormous quantities of incompatibility part.
Summary of the invention
The utility model provides a kind of boring tool, the groove in just can machining box part endoporus on common boring machine.
The technical scheme that its technical problem that solves the utility model adopts is: utilize knife bar with rotation the moving of hole of certain angle being arranged, realize radial feed, thereby process the groove in this hole.
The beneficial effects of the utility model are, can be quickly and easily in the endoporus of part car go out the groove of certain width.
Boring tool is made up of cutter hub, guide pillar, circlip for hole, sliding sleeve, pin, deep groove ball bearing, thrust ball bearing, boring cutter, interior hexagonal flush end holding screw, flexible knife bar, adjustment screw, positioning sleeve, locking nut, overcoat, pad, hex nut, spring washer, plain washer, spring and screw plug.Boring cutter is contained in the circular hole of flexible knife bar front end and compresses with interior hexagonal flush end holding screw, the adjustment screw is contained in the screw of flexible knife bar front end, the end face of adjusting the cylinder of screw front end withstands on the rear end end face of boring cutter, flexible knife bar is contained in the inclined hole of cutter hub, pin is contained in respectively on the flexible knife bar and the hole cutter hub axis normal and the sliding sleeve in the corresponding hole by the groove on the cutter hub, sliding sleeve is contained on the cylinder of the big end of cutter hub, overcoat is contained on the sliding sleeve by two deep groove ball bearings and thrust ball bearing and retaining pad, positioning sleeve is contained in the overcoat endoporus in front by screw thread and fixes with locking nut, guide pillar withstands on the rear end of flexible knife bar, screw plug is contained in the screw of cutter hub rear end, and spring is contained between guide pillar and the screw plug.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the installation diagram of boring tool.
