Abstract
The utility model discloses a cutting force fastening self-protection adjustable cutting tool which is composed of a cutter head of which the tail end is provided with a column threaded rod, a cutter body composed of a square clamp sleeve, a cutter blade, a cutter shim, a cutter blade baffle plate, a screw bolt, a nut, a gasket, etc. The left side of the cutter head is provided with a cutter groove in a milling way; the bottom and the right side of the cutter groove are provided with screw holes; the inside of the screw hole is screwed with an adjustment bolt; the cross section of the square clamp sleeve is in the shape of outer square and inner circle to realize the adjustment of the re-milling, the indexing, the interchanging, the front and back corner, the main and side angle and the edge inclination angle of the cutter blade. The utility model has the advantages of wide working range, fastening of leaning on the cutter, stable and reliable clamping, high efficiency, multiple functions, wide adaptability, long service life, low cost, etc. Therefore, the utility model is an ideal and new-style cutter. The cutting force fastening self-protection adjustable cutting tool is particularly suitable for carts, millings and planers.
Description
The utility model belongs to machine tool, is specially adapted to car, mills, planer.
Existing cutter can divide three kinds of structures:
1, Welding Structure: this structure is that carbide chip is welded on the knife bar open slot, and is simple and compact for structure, good rigidly.But carbide chip welding back quality descends, and utilization rate low (only accounting for 30%) waste is big; The range of work is narrow, and requirement is big, and is wide in variety; Blade and cutter groove faying face are with the blade reconditioning, and area successively decreases synchronously, and productivity ratio reduces; Tool changing, toolsetting time are long; Knife bar corase grind amount is big, and the labour intensity height is seriously polluted, and blade very easily cracks; Knife bar can not reuse, and causes a large amount of wastes of steel and manpower.
2, the clamping structure of refacing: be with blade in various manners clamping on the cutter groove, and certain adjustability of refacing is arranged, good rigidly and reliable, the remainder sharpening is shaped, than brazed shank tool is convenient, durable, productivity ratio is high, cost is low.But the angle is non-adjustable before and after the cutting edge, and refacing is restricted; The blade utilization rate is not high; The range of work is narrow.
3, indexable throw away structure: be the polygon indexable insert tip, throw away tip to be clamped on the knife bar with various multi-form tightening members.Though this mechanism overcomes some shortcomings of above two kinds of mechanisms, the angle is all non-adjustable before and after the cutting edge, blade assembly precision height in addition, utilization rate is lower, be difficult to adapt to complicated, change various processing conditions, economic benefit is not good.
More than three kinds of mechanisms all do not have self-insurance, unexpected overload causes the accident unavoidably, the influence safety in production.
It is wide that the purpose of this utility model aims to provide a kind of range of work, and blade can be refaced, transposition, exchange, angle, front and back, tool cutting edge angle, cutting edge inclination is all adjustable, and clamping is reliable and stable, the efficient height, function is many, and cost is low, the adjustable cutter of the fastening self-insurance of cutting force that the life-span is long.
The utility model is made up of cutter hub, blade, edge bearing, blade baffle plate, nut, packing ring etc.And cutter hub is by the cutter head and the square retaining sleeve formation of afterbody band cylindrical screw (centre is the cylinder knife bar).So that angle and cutting edge inclination before and after the adjustment cutting edge, Rotate 180 ° can satisfy positive and negative cutting, and more important role is when cutter is unexpected when crossing section, and the cutter head knife bar rotates to an angle in square retaining sleeve, avoid having an accident, and self-insurance.
Being milled with wide a 7～15mm in the cutter head left side, is the groove of 12～16mm deeply, and the thickness on its groove top is 6～9mm, and the thickness of bottom is 9～11mm.To guarantee the intensity and the elasticity extruding force of required quality of fit and cutter groove top and the bottom, cutter is worked smoothly under the condition of normal cutting-in and feed.
Cutter groove bottom is provided with 1 screw at least, is screwed with one on it at least and adjusts bolt; The cutter head right side is provided with 2 screws at least and is screwed with 2 on it at least and adjusts bolts, and the centre-to-centre spacing of two bolts is 10mm.The length that blade stretches out the cutter groove is 4～10mm, and centre-to-centre spacing is that 2 of 10mm adjust advance and retreat amount and the drift rate that bolt can be used to adjust cutter.When the length of stretching out when blade is long, expand the power principle according to lever, cutting force becomes the fastening force clamp-on tool.The length of stretching out the cutter groove when blade in short-term, according to the frictional force principle, cutting force becomes self-lock force can not become flexible cutter.Dynamics also can be adjusted by the adjustment bolt of groove bottom.When the blade extension elongation is 4mm, with regard to inconvenient reconditioning, can unclamp the adjustment bolt of groove bottom, take out blade, transposition is used.
It is reasonable for the cooperation that guarantees cutter that square retaining sleeve cross section is made square-outside and round-inside shape, and easy to adjust and enough intensity is to satisfy the needs of self-insurance.

Embodiment 1:
The knife bar of the cutter head (1) of afterbody band cylindrical screw partly is pressed into square retaining sleeve (7), load onto elastic washer (8) at the screw portion that exposes square retaining sleeve (7) one ends, overlap top nut (9) again, mix up required angle, after treating nut (9) pretension, arbitrary standardized baseline at square retaining sleeve (7) and nut (9) is as the criterion with baseline, nut (9) twisted 3/4ths circles get final product.Perhaps use torque-indicating wrencg fastening nut (9), twisting torsion eventually is 180N, so that self-insurance when the maximum depth of cut.In the cutter groove, be bumped into edge bearing (3) successively, blade baffle plate (6) and blade (2), in the screw of cutter groove bottom, be screwed into again and adjust bolt (4), in the screw on cutter head (1) right side, be screwed into again and adjust bolt (5), adjust required advance and retreat amount, side-play amount, cutting edge tool cutting edge angle (its adjusting range is 15 °) and clamping dynamics, to guarantee the smooth work of cutter.
Embodiment 2:
Present embodiment is the modified of embodiment 1.The cylinder knife bar of the cutter head (01) of afterbody band screw rod partly is pressed into square retaining sleeve (011), loads onto elastic washer (012), cover top nut (013) mixes up required angle, according to implementing 1 described method fastening screw nut (013).In the cutter groove, be bumped into edge bearing (03), blade baffle plate (07), blade baffle plate (08), blade (04) and blade (02) successively and in the screw of cutter groove bottom, be screwed into 2 adjustment bolts (05) again, in 2 screws on cutter head (01) right side, be screwed into 2 again and adjust bolts (06).Set up a rectangle convex (09) at square retaining sleeve (011) by the left surface of cutter head one end, which is provided with screw, in screw, be screwed with and adjust bolt (010), present embodiment removes has increased blade (04), outside baffle plate (08), convex (09), the adjustment bolt (010), all the other are identical with embodiment 1.
The utility model Yu Xian You technology Xiang ratio, it is wide to have the range of work, but blade Chong mill, Zhuan Wei, exchange, front-and-back angle, tool cutting edge angle, cutting edge inclination is all adjustable, fastening by Tool in Cutting power, clamping Wen is surely reliable, Xiao leads height, and function is many, wide adaptability, life-span long (Wei universal cutter 3～5 times), cost is low, and (be three/Yi of brazed shank tool, the You points such as ten/) of clamping throwaway tool are the desirable new-type cutter of Yi Zhong.
