Abstract

The utility model relates to a cutter for metal cutting work, which is suitable for a cutting head of long service life for strong planning and a fullcut plane cutter the front angle of which is adjustable. The utility model is characterized in that the cutting head can be resharpened for a plurality of times and is of long service life; the front angle of the cutter can be adjusted randomly according to the cutting need and the reticule reading. The main structure of the cutter is that the cutting head (7) is of strip shape, the front cutter surface is of platform shape; a main cutting edge is arranged at two ends, along the length direction, of the surface; clamped inclined planes at two sides are of swallow-tailed shape; the bottom surface is provided with retaining insection. A cutter body (4) is provided with a slant profiled slot, which is provided with a clamping bolt (5), a clamping inclined block (6) and a retaining block (8) inside which can fixedly clamp the cutting head (7). The joint of a cutter handle (3) and a cutter body (4) is of tine clutch structure and is locked by a fastening bolt (1) and a cushion ring (2). The cutting head is manufactured by high-speed steel, thus being suitable for a frame planer to strongly plan common plain carbon steel and alloy steel working parts.

Description

Long-life cutter head, the clip type planing tool that anterior angle is adjustable

Affiliated technical field

The utility model relates to a kind of cutter of metal cutting manufacture field, especially is applicable to the long-life cutter head of powerful planing, the clip type planing tool that anterior angle is adjustable.

Background technology

In the metal cutting machining tool, metal-planing machine has enough power and rigidity.Big when good rigidly, the machined surface of work piece, when allowance is big, be suitable for adopting the method for powerful planing most, make every effort in a force plane, cut whole roughing surpluses, to reach the purpose that improves planer efficient.

At present, the powerful planing tool that is used for metal-planing machine has three kinds of welded type, clip type and assembleds, and back two kinds are subjected to structural limitations, only are suitable for the gray iron casting of planing, and have only the powerful planing tool versatility of welded type good.For example: " the 65 ° of powerful planing tools of welded type " introduced in " tryingplane, insert worker's technology " that China Machine Press publishes (2000 January the 1st edition) book is to use more a kind of powerful planing tool at present.Think that through examination following shortcoming is arranged: 1. tool weight is big, and the area of back knife face is big, and reconditioning cutting edge effort is time-consuming; 2. the width of blade is little, and the number of times that can repeat sharpening is few, and cutter life is short; 3. anterior angle is bigger than normal, can not adjust again, unsuitable powerful planing high rigidity, high-intensity steel part.

Summary of the invention

In order to overcome the defective that above-mentioned powerful planing tool reconditioning cutting edge effort is time-consuming, cutter life short, anterior angle can not be adjusted, the utility model provides a kind of adjustable clip type planing tool of long-life cutter head, anterior angle that is applicable to the powerful planing of metal-planing machine.

The utility model is that the technical scheme that its technical problem of solution is taked is:

1. cutter head high-speed steel manufacturing, integral body is strip, and rake face is platform-like, and main cutting edge is at these length direction two ends, plane, and clamped inclined-plane, both sides is dovetail shaped, and there is horizontal stop groove the bottom surface.

2. oblique special-shaped groove is arranged at the cutter hub bottom, the dovetail groove of cutter head can be installed and clamp to the tight bolt of interior clamping and clamp skewback with the common composition of cutter hub, retreats when stoping cutter head to be subjected to strong cutting force for reliable, at cutter head installed surface middle part, end face tooth of synchronous belt, the female scotch in bottom surface are arranged; At the cutter hub back side hold-down nut is arranged, the differential tight fixed bolt of interior dress twin-stage screw thread, another of this bolt grade screw thread is connected with scotch, because differential principle, the forward and backward moment is moved tight fixed bolt, can make the engagement of scotch groove and cutter head and break away from; There is graduation mark on cutter hub top for short Cylinder, the oriented apex of the heart tooth of end face, i.e. and pointed tooth clutch, the centre is an internal thread, is used for and being connected of handle of a knife; Internal thread center line and cutter head installed surface have an angle, i.e. the negative side rake of cutter.

3. handle of a knife bottom and end face structure are identical with cutter hub top, on same center line, are the through hole that passes handle of a knife, for fastening bolt is installed.

So far, fastening bolt is the locking of handle of a knife and cutter hub, in the cutter hub dovetail groove of then cutter head being packed into, and with the groove engagement of scotch, locking fishbolt and differential tight fixed bolt promptly can be used for powerful planing.

The beneficial effects of the utility model are: the cutter integral rigidity is good, and cutter head clamps firmly, and stop device is arranged, and is suitable for common carbon steel|, high strength are closed the brute force planing of steel; Cutter head can repeat sharpening often, the life-span is long; According to the cutting needs, tool orthogonal rake can arbitrarily be adjusted.

Description of drawings

Below in conjunction with Figure of description the utility model is further specified.

Fig. 1 is a front view of the present utility model, and cutter head stretches out the cutter hub length L should be as far as possible little, according to the anterior angle size, is generally 6～12mm.

Fig. 2 is the A-A insight structural map of Fig. 1, this figure basic representation the internal structure of cutter.

Fig. 3 is the B-B insight structural map of Fig. 1.

Among the figure: 1, fastening bolt 2, packing ring 3, handle of a knife 4, cutter hub 5, fishbolt

6, clamp skewback 7, cutter head 8, scotch 9, drive nut 10, jackscrew

11, hold-down nut 12, differential tight fixed bolt

The specific embodiment

Among Fig. 1, fastening bolt (1) passes packing ring (2) can be with handle of a knife (3) and firmly locking of cutter hub (4); On cutter hub, the effect of fishbolt (5), clamping skewback (6) is to clamp cutter head (7).Because cutter head (7) two ends are main cutting edge, in the application, if blade wearing and tearing, adjustable another blade of rotor head, reconditioning together afterwards.

The adjustment of tool orthogonal rake must be undertaken by the planer head clamped condition in handle of a knife (3), unclamp (1) 1～2 week of fastening bolt, cutter hub (4) just can fall, break away to end tooth, it is turned to required angle, by the graduation mark reading, hold up cutter hub (4) then and make the end tooth engagement, locking fastening bolt (1) gets final product.

Among Fig. 2, fastening bolt (1) is with handle of a knife (3) and firmly locking of cutter hub (4); Fishbolt (5) passes and clamps skewback (6) and be connected with cutter hub (4) and clamp cutter head (7); Scotch (8) is in cutter hub (4), its top groove and the engagement of cutter head (7) groove, scotch (8) other end is connected with the differential tight fixed bolt (12) at cutter hub (4) back side, another of this bolt grade screw thread is connected with hold-down nut (11), because above-mentioned structure, when clamping or when taking off cutter head (7), must take into account engagement or disengaging with scotch (8) groove; Driving nut (9) is fixed on the fishbolt (5) by jackscrew (10), apart from clamping skewback (6) gap of 0.5mm is arranged, when needs take off cutter head (7), unclamp fishbolt (5), Lian Dong drive nut (9) is just mentioned clamping skewback (6) automatically with it, removes the clamped state of cutter head (7); Handle of a knife (3) has negative side rake λ s with cutter head (7).

Among Fig. 3, further represented scotch (8) and cutter head (7) groove engagement and with being connected of differential tight fixed bolt (12).Illustrated tool orthogonal rake is 0 °, and the angle at back knife face place is γ ₀+ α ₀(anterior angle and relief angle sum) is when tool orthogonal rake is adjusted to γ ₀The time, just have only tool clearance α ₀.
