Abstract
The utility model relates to a clamp type threading tool of an eccentric compactor. The clamp type threading tool consists of a blade, a tool bar, an eccentric sleeve, an eccentric screw and a nut, the blade is arc-shaped, a cylindrical surface which matches with an outwards convex surface of the blade is disposed on the head of the tool bar, the eccentric screw penetratingly matches with the tool bar via an assembling hole arranged on the tool bar and penetrates through the eccentric sleeve, so that the blade is pressed on the tool bar, the blade and the tool bar are fixed via the nut, and the eccentric screw is provided with a cylindrical surface matching with an inwards concave arc surface of the blade. The clamp type threading tool of the eccentric compactor adopts the arc-shaped blade, accordingly has better vibration resistance and bending resistance, can protect a non-cutting portion of the blade, prevents the non-cutting portion from being damaged by scrap iron, is quite convenient in assembling, disassembling and grinding after being abraded and longer in service life, has the advantages of high processing efficiency and fine processing precision compared with a regular turning tool, and is quite suitable for self manufacturing and application of small and medium-sized enterprises.
Description
Technical field
The utility model relates to a kind of lathe tool, and especially a kind of off-centre compresses the clip type threading tool.
Background technology
The machine clip variable-position lathe tool is that indexable carbide chip is clamped in the lathe tool that forms on the knife bar with mechanical method, when some stainless steel materials of turning such as 1Cr18Ni9Ti external screw thread, intensity is big, hardness is higher because this type of material has, the characteristics that smear metal is not easy to fracture, cause the screw thread machined surface roughness poor easily, the cutter defective such as quickening, service life be low of damaging easily, wear and tear, comparatively inconvenience of the sharpening of cutter simultaneously, when therefore processing this type of stainless steel material external screw thread, can not obtain satisfied crudy and guarantee working (machining) efficiency.
The utility model content
The purpose of this utility model provides a kind of off-centre and compresses the clip type threading tool, with the unfavorable problem of avoiding occurring when the turning high-strength stainless steel material of processing effect.
For achieving the above object, the utility model adopts following technical scheme: a kind of off-centre compresses the clip type threading tool, this lathe tool is made up of blade, knife bar, eccentric bushing, eccentric screw and nut, described blade is a circular arc, knife rod head has the face of cylinder that matches with the outer convex surface of blade, described eccentric screw installs with it by pilot hole set on the knife bar and cooperates, eccentric screw pass eccentric bushing with blade pressing on knife bar, fix by nut; Described eccentric screw has the face of cylinder that cooperates with the blade inner concave arc surface.
Be provided with packing ring between described nut and the eccentric bushing.
Described blade is a Hardmetal materials.
Off-centre of the present utility model compresses the clip type threading tool and adopts the circular arc blade; thereby the vibration resistance of cutter and flexing resistance are better; can protect the blade of not participating in cutting tip; avoid the damage of iron filings; and dismounting after the tool wear, sharpening are very convenient; cutter life is longer, compares the characteristics that regular turning tool has working (machining) efficiency height, good processing accuracy, is very suitable for medium-sized and small enterprises and makes voluntarily and use.
For making the clamping better effects if, add packing ring at nut and eccentric bushing support.
Description of drawings
Fig. 1 is the sectional view that the utility model off-centre compresses the clip type threading tool;
Fig. 2 is the vertical view that the utility model off-centre compresses the clip type threading tool;
Fig. 3 is the vertical view of the utility model blade;
Fig. 4 is the side view of the utility model blade.
The specific embodiment
Below in conjunction with concrete embodiment the utility model is done further introduction.
As Fig. 1～Figure 2 shows that a kind of off-centre of the utility model compresses clip type threading tool embodiment, as seen from the figure, this lathe tool is made up of blade 5, knife bar 6, eccentric bushing 3, eccentric screw 4 and nut 1, blade 5 is a circular arc, knife bar 6 heads have the face of cylinder that matches with the outer convex surface of blade, eccentric screw 4 installs with it by pilot hole set on the knife bar 6 and cooperates, and eccentric screw 4 has the face of cylinder that cooperates with the blade inner concave arc surface; Eccentric screw 4 passes eccentric bushing 3 blade 5 is pressed on the knife bar 6, fixes by nut 1.Blade adopts carbide alloy YG6T, and service life is longer, and arc surface blade circular arc length can reach 80 ~ 100mm, thereby can repeatedly reface.The knife bar material is 45 steel, and hardness is HB235 ~ 250 after modifier treatment.The cylindrical axis of eccentric bushing and internal control axis be not on same straight line, thereby eccentric bushing and knife bar are that turn installs and cooperates installation.When blade was installed, blade 5 external arc surface utilized the eccentric hold-down mechanism of eccentric bushing 3, eccentric screw 4 compositions with after knife bar 6 arc surfaces cooperate, and blade 5 is pressed on the knife bar 6, only need unclamp nut 1 during the dismounting blade, discharges eccentric hold-down mechanism and gets final product.The eccentric bushing material is 45 steel, and hardness is HRC40 ~ 50 after the heat treatment, makes it have higher wearability.To compress effect horizontal good in order to make, and adds packing ring 2 between nut and the eccentric bushing.
This lathe tool tool orthogonal rake can be formed naturally by arc surface, also can suitably carry out reconditioning, and is brisk for making working angles generally speaking, tool orthogonal rake γ=12 °; All relief angle α=6 °.This lathe tool cutter can use on each model engine lathe such as C620, C6140, C630.When adopting this external threading cutter processing stainless steel external screw thread, cutting speed v=40 ~ 50m/min; Cutting depth t=1.5mm divides three cutter cars to become, and working (machining) efficiency can improve more than the several times, and the thread surface roughness is less than Ra1.6 μ m, and cutter structure novelty, easy accessibility can be obtained gratifying processing effect.
Off-centre of the present utility model compresses the clip type threading tool and adopts the circular arc blade; thereby the vibration resistance of cutter and flexing resistance are better; can protect the blade of not participating in cutting tip; avoid the damage of iron filings; and dismounting after the tool wear, sharpening are very convenient; cutter life is longer, compares the characteristics that regular turning tool has working (machining) efficiency height, good processing accuracy, is very suitable for medium-sized and small enterprises and makes voluntarily and use.
