Abstract
A floating boring tool comprises a round cutter head. A square groove is arranged on the head face of the cutter head along the radial direction. A floating boring cutter is arranged inside the square groove, with the blade end extruding the circumferential surface of the cutter head. A boring bar connecting screw is arranged at the center of the cutter head; a round platen is fixedly connected at the other head face of the cutter head through bolts. Four columned dead holes are arranged on the external circumferential surface of the platen, evenly dividing the external circumferential surface of the platen; each dead hole is provided with a floating slipper block inside and a spring is arranged between the bottom of the dead hole and the floating slipper block. The platen and floating bearings are arranged on the boring cutter head and the rigidity of the boring tool is improved through the interaction between the floating bearings and the inner walls of the inner holes, thus avoiding vibration during the boring process and improving processing quality. Connected in an adjustable mode, the boring tool is prolonged in service life and is widened in application range.
Description
Technical field:
The utility model relates to mechanical field, relates in particular to the machining frock, particularly a kind of unsteady borer.
Background technology:
Often need be on lathe or boring machine in the production hole of boring major diameter, the big degree of depth.Because the hole is big and dark, the rigidity of workpiece and cutter is relative relatively poor.In the prior art, adopt traditional cutter processing major diameter, the hole of the big degree of depth, because the boring cutter bar extension elongation is big, very easily produce vibration, crudy is poor, for example at this thin and long part of processing motor casing, is difficult to realize design accuracy.
Summary of the invention:
The purpose of this utility model provides a kind of unsteady borer, and described this unsteady borer will solve vibration cutting in the process in boring major diameter in the prior art, big degree of depth hole, influence the technical problem of crudy.
This unsteady borer of the present utility model is made of the cutterhead of a circle, wherein, be provided with a square groove in the end face of described cutterhead, on the radial direction that axially is positioned at cutterhead of described square groove, be provided with a floating boring tool in the square groove, the sword end of described floating boring tool is outstanding from the periphery of cutterhead, be provided with the gap between floating boring tool and the square groove, the central authorities of cutterhead are provided with at least three boring bars and connect screw around its axle center, be fixedly connected with the platen of a circle on the end face of cutterhead by screw, the medium branch of the outer circumference surface of described platen is provided with four columned blind holes, be provided with a floating slider in any one described blind hole, be provided with spring between the bottom face of described floating slider and blind hole, porose in the floating slider along axially being provided with of blind hole, be provided with screw in the bottom face of blind hole, be provided with a screw in the hole of floating slider, described screw is connected with the bottom face of blind hole.
Further, be provided with a sector notch in the end face of described cutterhead.
Further, described platen equates with cutter diameter.
Further, described floating slider is made of the tin bronze material.
Operation principle of the present utility model is: be connected screw with boring bar by screw and cutterhead be fixedly attached on the end face of boring bar, floating boring tool and platen enter in the workpiece hole to be processed, under the effect of spring force, floating slider contacts with the hole inwall of workpiece to be processed all the time, improve the rigidity of boring bar, prevented the vibration of boring bar or workpiece.Floating slider can obtain wearability by the tin bronze manufacturing, and does not scratch workpiece.Floating boring tool is an adjustable type, can improve its service life and the range of work.Concrete, the bottom outlet before the right boring will guarantee its shape and position of related features, generally stays allowance 0.06～0.15mm.Add man-hour,
The utility model and prior art contrast, and its effect is actively with tangible.The utility model is arranged at platen and floating support on the boring head, act on the rigidity that improves boring cutter mutually by floating support and inner hole wall, avoid when boring, producing vibration, improve crudy, boring cutter adopts adjustable connected mode, can improve its service life and the range of work.
Description of drawings:

As depicted in figs. 1 and 2, unsteady borer of the present utility model is made of floating boring tool 5 and boring cutter bar 8, wherein, be provided with boring head at described boring cutter bar 8 one ends, described floating boring tool 5 is arranged on the described boring head, described boring head is by cutterhead 6, platen 9 and floating slider 3 constitute, described cutterhead 6 one ends are connected with described boring cutter bar 8, described cutterhead 6 other ends are provided with the cutter groove 10 that runs through its diameter, described floating boring tool 5 is arranged in the described cutter groove 10, and described floating boring tool 5 keeps certain fit clearance with described cutter groove 10, described platen 9 is arranged at described cutterhead 6 other ends, described platen 9 is the disks with described cutterhead 6 equal diameters, even distribution of the circumferencial direction of described platen 9 a plurality of cylindrical holes are set, described floating slider 3 is arranged in the described cylindrical hole, be provided with spring 2 between at the bottom of described floating slider 3 one ends and the described cylindrical hole hole, described floating slider 3 is arranged in the described cylindrical hole by screw 4.
Further, described cutterhead 6 is incomplete disks, removes two arch sections by a disk symmetrically along its central shaft and constitutes.
Further, described floating slider 3 is at least 4 for amount.
Further, described floating boring tool 5 is made of blade 51 and cutter hub 52, and described blade 51 is arranged on the described cutter hub 52 by screw 53.
Further, described cutterhead 6 is connected with described boring cutter bar 8 by screw 7.
Further, described platen 9 is arranged at described cutterhead 6 other ends by screw 1.
Further, described floating slider 3 is made of tin bronze.
