Abstract
The utility model provides a technical proposal of a deep hole variable diameter boring cutter used for machining deep holes with special shapes. The technical proposal is characterized in that a through groove is processed on the side wall of a cutter body of a cylindrical sleeve body; a cutter base with a blade can be radially moved along the cutter body and is arranged in the groove, and an adjusting core rod capable of axially moving along the cutter body is arranged in the inner cavity of the cutter body. A bevel matched with a bevel on the cutter base and connected with complementary concave convex grooves is processed on the adjusting core rod. Thereby, the movable adjusting core rod is formed, that is, the deep hole variable diameter boring cutter can change the radial position of the cutter base to realize variable diameter processing.
Description
The utility model relates to the machining cutter, especially the Deep hole variable diameter boring cutter of deep hole machining machinery usefulness.
In recent years, the requirement that constantly proposes to process deep taper hole, vasiform orifice or special moldeed depth hole in industries such as Aeronautics and Astronautics, plastics machinery, light industry and machinery., the used cutter of existing deep hole machining machinery can only the processing column hole.Because it is do not have to realize the reducing cutter of reducing processing, so very difficult to the processing in special moldeed depth hole.
The purpose of this utility model does not have the reducing cutter at prior art exactly, be difficult to process the problem in special moldeed depth hole and provide a kind of can reducing, the technical scheme that can process the Deep hole variable diameter boring cutter in special moldeed depth hole.
For achieving the above object, this programme has adopted the cylindrical cutter body that will have the cutter hub connection handle to be processed into cylindrical body, on its sidewall, be processed with the groove that matches with plate shape tool rest four sidewalls, the tool rest that can move radially and be equipped with blade along cutter hub is housed in this groove; Be equipped with at the cylindrical cavity of cutter hub and cooperate with it and axially displaceable adjusting core bar, an end of this adjusting core bar is processed with the core bar connection handle, and the other end be processed with an inclined-plane with tool rest on the inclined-plane guide groove that matches and be connected.Reconciling core bar and the tool rest guide groove that merging is connected that matches is the emboss pit of the complementation of each one-sided processing in comfortable joint.
This programme is owing to be processed with groove on the sidewall of cover shape cutter hub, the tool rest of band blade is housed in it, and the inclined-plane of regulating on the core bar in tool rest and the cutter hub inner chamber is connected, when the adjusting core bar is mobile vertically in cutter hub, tool rest will change the radius of clean-up of blade along with along the moving radially of cutter hub together with blade.Therefore, in machining, as long as moving of control and regulation core bar can change radius of clean-up and realize reducing processing.This shows that the utility model compared with prior art its effect is conspicuous.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 looks schematic diagram for the right side of Fig. 1;
Fig. 3 is that the A-A of Fig. 1 is to cross-sectional schematic.
Below by a specific embodiment and in conjunction with its accompanying drawing, the utility model is further elaborated.Deep hole variable diameter boring cutter has a cutter hub 5 that has a cutter hub connection handle 2, this cutter hub 5 is cylindrical bodies, on its sidewall, be processed with the groove that matches with plate shape tool rest 3 four sidewalls, just adorning in this groove and can move radially, and the tool rest 3 of three groups of indexable coated chips 4 is installed along cutter hub 5.Cooperate with it and axially displaceable adjusting core bar 7 and be equipped with at the cylindrical cavity of cutter hub 5, an end of this adjusting core bar 7 is processed with core bar connection handle 1, and the other end be processed with an inclined-plane with tool rest 3 on the inclined-plane match and be associated with the guide groove that slidably is connected.Described conciliation core bar and tool rest match and are associated with the emboss pit that the guide groove that is slidingly connected is the complementation of each one-sided processing in comfortable joint.And the inclined-plane on the described adjusting core bar 7 can be processed into 4: 1 inclined-plane.In addition, on the outer wall of described cutter hub 5 parallel tool rest 3 planes directly through locating setting-in one or two guide pads 6, present embodiment is two.Be embedded with two guide pads 9 on vertical tool rest 3 planes and at the Zhi Jingchu of its cutting face dorsal part again, the suffered radial load of cutter hub 5 when being used for bearing cutting.Also have on the sidewall of cutter hub 5, the intake chute B that tool rest 3 cutting face sides are processed with cooling fluid communicates with the inner chamber of cutter hub 5, with so that cooling fluid except that Castor Oil and cooling cutting, can also be with the smear metal of cutting cutter hub 5 inner chambers by tool rest 3 front ends towards draining.The width of this intake chute 8 can determine according to the size of cutting output and smear metal, generally can be between the cutting face of tool rest 3 between the 30-40 angle.
