Abstract
The utility model relates to a cutter used for lathes and boring machines of an interchangeable and special material blade. The utility model is composed of a square cutter body, a screw rod cutter head body with graduation nut, and a conical surface pin lock rotating device, wherein, the cutter head body is strained by a screw in the inner hole of the cutter handle. The utility model has the advantage of simple and reasonable structure. The dimension of a boring cutter, the different main and deflection angle of a cutting blade, and the cutting direction of the cutting blade are all selected according to the requirement. The fine adjusting boring cutter of the utility model can carry out fine adjustment finish cutting on a square hole boring bar used by a common boring machine, and can also be used for machine tools of lathes, machining centers, etc.
Description
The utility model relates to interchangeable, the cutter that is used for lathe and boring machine of special material blade.
Micrometer adjustement boring tool at present domestic general be the column type boring cutter that blade tilts, it can only with the supporting use of the boring bar of special use.Accompanying drawing 1 be West Germany come that China puted on display examine Manta (Komet) square micrometer adjustement boring tool, Fig. 2,3, the 4th, the enlarged drawing of the worm bit of the protruding key of part, keyway cover and band calibration nut, the tension of its cutter head is the structure with one group of helical spring or disc spring, prevent cutter head rotating part jacket layer complexity, part rigidity intensity difference is made the boring cutter of small size, must influence the stability of service precision, therefore can not be used for the processing of aperture, manufacturing cost is also than higher.
The purpose of this utility model provides a kind of simple structure, well behaved micrometer adjustement boring tool newly designs, its size can design very for a short time, it have applied widely, need not special special-purpose boring bar, on the square hole boring bar that general boring machine uses, can finely tune precision cutting, also can be used for doing on the lathe lathe tool and use, and be used for accurate fine boring machine and machining center etc.
The purpose of this utility model realizes by following structure, strain with a screw rear end of the worm bit body of band calibration nut, screw is from the back handle of square cutter hub, on the convex shoulder of the packing ring side of being encased in cutter hub endoporus, threaded portion is screwed into and realizes tension in the cylinder inner bolt hole of worm bit body; On the external cylindrical surface of worm bit body, mill out an inclined-plane, adopt inclined-plane pin and its driving fit, prevent to relatively rotate, the top of inclined-plane pin is with a flush end holding screw, adjust and fix, make the free only telescopic moving of worm bit body and can not rotate, reach the requirement of reliable and stable work.The length and the size dimension of side's cutter hub, and different tool cutting edge angles, the cutting direction of blade all can design selected on demand.
Accompanying drawing 5 is structure charts of the utility model square micrometer adjustement boring tool, and accompanying drawing 6 is A-A cutaway views of accompanying drawing 5, has provided the driving fit structure of inclined-plane pin and worm bit body ramp.1 side's of being cutter hub among the figure, 2 is the worm bit body, and 3 is the calibration nut, and 4 is carbide chip, and 5 is sunk screw, and 6 is the inclined-plane pin, and 7 is holding screw, and 8 is packing ring, 9 is screw.
Provide embodiment of the present utility model in conjunction with the accompanying drawings.
Side's cutter hub 1 is made by common chromium steel, and inside is processed with manhole, and an end in hole has a convex shoulder, and the other end has-30 ° the conical surface; The middle part is processed with the circular hole of an installation inclined-plane pin, and the circular hole outer end is shaped on screw thread.One end of worm bit body 2 is for installing the cutter head of blade, the centre is the screw thread through grinding, requiring has good cooperating with the screw thread of calibration nut, significantly loosening phenomenon must not be arranged between them, being processed with one section gradient on the cylindrical outer surface of screw thread lower end is the inclined-plane of 11 degree, it is fixed that its length is come according to amount trimmed, and cylindrical end has an endoporus, and has attacked screw thread.If 0.5 millimeter of the thread pitch on fine-tuning nut 3 and the worm bit body that matches, calibration 50 lattice on the circumference of calibration nut, the blade that is used for right angle dress is moving 1 lattice of revolution then, and amount trimmed is 0.01 millimeter, same blade tilt 53 ° 8 ' body of tool bit, calibration 40 lattice, can obtain same trimming precision, calibration nut one end is shaped on turret head, carries out calibration on the inclined-plane below the turret head, the other end is the inclined-planes of 30 degree, matches with the conical surface on the square cutter hub 1.The inclined-plane pin has the inclined-planes of-11 degree, require with the worm bit body on the inclined-plane driving fit, regulate with the flush end holding screw, and make the worm bit body 2 can only telescopic moving, and can not relatively rotate.Packing ring 8 and screw 9 are standard fasteners, are used for stretching screw body of tool bit 2, after the fine setting, tighten screw 9 and make cutter head can not produce telescopic moving, to guarantee machining accuracy.
The utility model micrometer adjustement boring tool can improve machining accuracy, is applicable to Precision Machining, and simple and reasonable, can be widely used in the lathes such as boring machine, lathe and machining center, is a kind of very promising cutting tool. Fine practicality is arranged.
Claims (3)
1, square micrometer adjustement boring tool, by square cutter hub, the worm bit body, calibration nut and tensioning mechanism are formed, and it is characterized in that being milled with an inclined-plane on the external cylindrical surface of worm bit body, prevent structure in relative rotation with inclined-plane pin and its driving fit, the top of inclined-plane pin is with a flush end holding screw, adjusts and fixes; Worm bit body and function screw is strained.
2, according to the said square micrometer adjustement boring tool of claim 1, the gradient that it is characterized in that inclined-plane on the worm bit body and inclined-plane pin is 11 degree.
