Knife bar expansion regulating mechanism comprises knife bar, mandrel, push rod and end cap, and knife bar rear end is inclined-plane, and mandrel one end is the face of cylinder, and the other end is the scalene cone matched with inclined-plane, knife bar rear end; One end, the face of cylinder of mandrel connects push rod, and push rod distal center arranges regulating tank, and push rod end is threaded with end cap through end cap; End cap is evenly distributed with stepped hole, is connected with clamping bar by bolt.
The center, the face of cylinder of mandrel is disposed radially step groove, and one end that push rod is connected with mandrel is provided with the Step Shaft with mandrel step groove rotatable engagement.
Described regulating tank is six side's deep gouges.
The shape of cross section of knife bar is octagon.
The utility model is the multiple blade of even clamping on knife bar, add the position of cutter and absorption surface, make workpiece stress balance, the structural principle of Honing process is utilized to make blade stretch out the adjustable length of clamping bar, realize the feeding operation of blade, reduce the vibration in thin-wall hole turning process, stabilize turning process, improve production efficiency and improve yield rate, there is very high economic benefit and practical value.

Detailed description of the invention
As shown in Figure 1 to Figure 3, a kind of multiple-cutting-edge lathe tool for thin-wall hole machining, comprise column type clamping bar 1, clamping bar 1 outer circumference surface is evenly provided with square hole 2, and square hole 2 is in-built accompanies knife bar 3, and knife bar 3 front end is that plane is cut and is fixed with blade, clamping bar one end end face is provided with blind hole 4, be provided with knife bar expansion regulating mechanism in blind hole 4, knife bar 3 front plan center is along the circumferential direction provided with elastomer tank 5, and elastomer 6 is positioned at elastomer tank 5 and fetters knife bar 3.
Knife bar expansion regulating mechanism comprises knife bar 3, mandrel 7, push rod 8 and end cap 9, and knife bar 3 rear end is inclined-plane, and mandrel 7 one end is the face of cylinder, and the other end is the scalene cone matched with inclined-plane, knife bar 3 rear end; One end, the face of cylinder of mandrel 7 connects push rod 8, and push rod 8 distal center arranges regulating tank 11, and regulating tank is six side's deep gouges, and push rod 7 end is threaded with end cap through end cap 9; End cap 9 is evenly distributed with stepped hole 10, is connected with clamping bar 1 by bolt.
The center, the face of cylinder of mandrel 7 is disposed radially step groove 12, and one end that push rod 8 is connected with mandrel 7 is provided with the Step Shaft 13 with mandrel step groove 12 rotatable engagement.The shape of cross section of knife bar 3 is octagon.
Clamping bar one end clamping is on turning tool rest, other end center is provided with the blind hole be slidably matched with mandrel and the screwed hole be connected with end cap, clamping bar circumferencial direction is evenly provided with the square hole be slidably matched with knife bar, for playing the effect into its slide-and-guide while limiting knife bar rotary freedom.
Knife bar is square-column-shaped, and knife bar one end is inclined-plane, and one end is plane, and one end, knife bar inclined-plane is arranged in the square hole on clamping bar, and lathe tool blade clamping is in one end of plane, and this end is provided with elastomeric tank, and elastomer fetters knife bar at circumferencial direction; Mandrel one end is scalene cone, be slidably matched with the inclined-plane of knife bar, mandrel other end end face center has been disposed radially step groove, push rod one end is provided with the Step Shaft with mandrel step groove rotatable engagement, under push rod effect, mandrel slides in the blind hole of clamping bar, by the slip on mandrel scalene cone and knife bar inclined-plane, simultaneously under elastomeric effect, knife bar is made radially to press to mandrel, prevent knife bar from coming off, realize the flexible of knife bar when mandrel slides in the blind hole of clamping bar, thus realize the adjustment of blade radial feed.Cut away on four of knife bar axial limits, the knife bar cross sectional shape after cutting is octagon, forms the little inclined-plane 14 preventing knife bar from interfering in contraction process.
