Abstract
The utility model discloses an assembling structure of a turning tool, which comprises a tool rod and a tool blade. A protruding block at the front end of the tool rod is provided with a notch, a groove is arranged on the bottom surface of the notch, a projection is arranged on the lower end face of the tool blade, the tool blade is arranged in the notch, a spherical projection on the tool blade matches with the groove on the bottom surface of the notch, a mounting hole communicated with the notch is arranged at the upper end of the projection, and a fastening bolt is in threaded connection with a threaded hole on the tool blade after penetrating through the mounting hole. Connection stability of the tool blade and the tool rod can be increased, and the assembling structure of the turning tool has the advantages of adjustability.
Description
Technical field
The utility model relates to the Machining Technology field, particularly a kind of assembly structure of lathe tool.
Background technology
Shaped profile turning cutter is a kind of detachable and repeat the metal cutting dedicated tool of sharpening, not only can be used for moulding of general rotary work piece Surface Groove and cutting, and is suitable for the processing and forming of groove dark and narrow on the end face especially.Generally speaking, all kinds of metal cutting work all must have corresponding cutter to cooperate, carry out and finish stock removal action.Mostly some lathe tools for present stage uses are to connect with screw between its turning insert and the knife bar, and this fixed form is also insecure, and promptly when the suffered active force of turning insert was excessive, it is loosening that turning insert is taken place.
Summary of the invention
The purpose of this utility model provides a kind of assembly structure of lathe tool, and the utility model can increase the steadiness that the lathe tool bar is connected with knife bar.
The technical scheme that realizes the utility model purpose is as follows:
The assembly structure of lathe tool, comprise knife bar and turning insert, the projection of described knife bar front end is provided with a recess, the bottom surface of this recess is provided with a groove, the lower surface of turning insert is provided with projection, and turning insert is arranged in described recess, and the groove of spherical surface hill on the turning insert and described recess bottom surface cooperatively interacts, described projection upper end is provided with the installing hole that is communicated with described recess, and trip bolt passes described installing hole and is threaded with screwed hole on the turning insert.
Also comprise a tool rest, this tool rest is provided with stepped hole, one end of described knife bar is positioned at the bigger diameter end of stepped hole, the miner diameter end of stepped hole is provided with the adjustment screw, this adjustment screw and knife bar end face connect against, the surface of described knife bar is provided with the adjustment groove, and the screwed hole that dog screw passes the tool rest upper surface is inserted in the adjustment groove on knife bar surface.
Groove in the described recess on the bottom surface is the groove of dome shape, and the projection of the lower surface of described turning insert is a spherical surface hill.
Adopted such scheme, the lower surface of turning insert is provided with projection, and turning insert is arranged in described recess, and the groove of spherical surface hill on the turning insert and described recess bottom surface cooperatively interacts, and by projection and the cooperating of groove, can increase the steadiness that turning insert is located.And after on the turning insert projection being set, also help the bulk strength that increases turning insert.
Tool rest is provided with stepped hole, one end of described knife bar is positioned at the bigger diameter end of stepped hole, and the miner diameter end of stepped hole is provided with the adjustment screw, this adjustment screw and knife bar end face connect against, adjust by the position of adjusting screw cutter knife bar, help improving machining accuracy workpiece.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
In the accompanying drawing, 1 is knife bar, and 2 is turning insert, and 3 is tool rest, and 4 is projection, and 5 is projection, and 6 is trip bolt, and 7 for adjusting screw, and 8 for adjusting groove, and 9 is dog screw.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
With reference to Fig. 1, the assembly structure of lathe tool of the present utility model comprises knife bar 1, turning insert 2 and a tool rest 3.The projection 4 of knife bar 1 front end is provided with a recess, and the bottom surface of this recess is provided with a groove, and this groove is the groove of dome shape.The lower surface of turning insert is provided with projection 5, the projection of the lower surface of turning insert is a spherical surface hill, turning insert is arranged in described recess, the groove of spherical surface hill on the turning insert and described recess bottom surface cooperatively interacts, projection upper end is provided with described recess and is communicated with installing hole, and trip bolt 6 passes described installing hole and is threaded with screwed hole on the turning insert.Tool rest 3 is used to be installed in lathe, and the lower end of tool rest 3 is provided with the mount pad that is used to be installed on the lathe.Tool rest 3 is provided with stepped hole, and stepped hole two sides from about the tool rest are passed.One end of knife bar 1 is positioned at the bigger diameter end of stepped hole, the miner diameter end of stepped hole is provided with adjusts screw 7, this adjustment screw 7 and knife bar end face connect against, the surface of described knife bar is provided with adjusts groove 8, the screwed hole that dog screw 9 passes the tool rest upper surface is inserted in the adjustment groove on knife bar surface, and knife bar is fixed in the stepped hole of tool rest.In the time of need doing fine setting to the position of lathe tool, unclamp dog screw 9, regulate and adjust screw 7, knife bar 1 is moved along its axis, after adjusting to the right place, screwed in place screw 9 makes the knife bar location again.
