Abstract
The utility model discloses a reverse chamfer cutter comprising a connecting taper shank, a cutter rod and a chamfer cutter body. The cross section area of a tool bit at the top end of the chamber cutter body is larger than that of the cutter rod; the outer surface of a connection segment between the tool bit and the cutter rod forms an inclined cutting surface; the connecting taper shank is a cone-shaped body with a top smaller than a middle; and the top of the connecting taper shank is provided with a rectangular fixed block. The reverse chamber cutter adopts a structure connected and matched with a drilling press spindle; and the cone-shaped body connected and matched with the drilling press spindle is of a uniform structure and meets the requirement for connection and fixation with a drilling press. The cross section area of the tool bit is larger than that of the cutter rod so that the outer surface of the connection segment between the tool bit and the cutter rod forms the inclined cutter body. The upper part and the lower part of a large workpiece can be chamfered simply by replacing the chamfer cutter without reversely fixing the large workpiece to be processed.
Description
Technical field
The utility model belongs to field of machining and machinebuilding technology, the special-purpose chamfering tool that especially uses to the reverse chamfering of boring manufacturing procedure.
Background technology
Chamfering is as requisite one important procedure of machining, because of its importance is directly connected to product assembling, transhipment, become must be in the design drawing clear and definite action of designer for this reason; But can satisfy most of product processing needs as Drilling Operations chamfering tool commonly used; In the time of can't it being inverted but the below in and hole big for workpiece needs chamfering, chamfering tool commonly used can not be realized the chamfering function, thereby make product processing can not reach Design Requirement Drawing; Usually adopt the mode of artificial polishing that chamfered area is carried out chamfering for this reason; Finally cause inefficiency and cost obviously rises, as processing work being inverted back chamfering, its complex procedures; Working (machining) efficiency is low, can not satisfy existing needs to the large-scale workpiece chamfer machining.
Summary of the invention
The utility model discloses a kind of reverse chamfering tool according to the deficiency of prior art.The problem that the utility model will solve provides a kind ofly can carry out reverse chamfer machining, avoids the reverse chamfering tool to large-scale processing work chamfering process is complicated, processing cost is high.
The utility model is realized through following technical scheme:
Reverse chamfering tool comprises connecting taper shank, knife bar and chamfering cutter hub, it is characterized in that: the cutter head cross-sectional area on said chamfering cutter hub top is greater than the knife bar cross-sectional area, and cutter head and knife bar linkage section outer surface form the cutting face of inclination.
Said connection taper shank is the bullet of top less than the middle part, and the rectangle fixed block is arranged at the top.
Above-mentioned reverse chamfering tool is through utilizing chamfering tool syndeton commonly used, and the original direction of its cutter hub made amendment changes machine direction and realize reverse chamfering.When using above-mentioned reverse chamfering tool, earlier clamping workpiece is put in place, connection taper shank one end of chamfering tool is passed needs chamfered bore again, is connected on the main shaft of drilling machine, and after installing, cutter hub just can carry out chamfering to chamfer site.
The utility model helpfulness is: the reverse chamfering tool of the utility model adopts and is connected matching structure with drill press spindle, and the bullet that is connected coupling with drill press spindle is unified structure, and adaptation is connected fixing needs with drilling machine; The cutter head cross-sectional area need need can not realized the chamfer machining to the workpiece top and the bottom by the replacing chamfering tool to following fixing of situation of large-scale processing work inversion greater than the cutting face of knife bar cross-sectional area formation cutter head and knife bar linkage section outer surface formation inclination.Thereby the utility model creative utilization chamfering tool device commonly used is made amendment the original direction of its cutter hub and is changed machine direction and realize reverse chamfering, and enhancing productivity reduces production costs.
Description of drawings
Fig. 1 is the reverse chamfering tool structural representation of the utility model;
Fig. 2 is the reverse chamfering tool machining state of a utility model sketch map;
Fig. 3 is the reverse chamfering tool rose reamer of a utility model body structure sketch map.
Among the figure, the 1st, chamfering cutter hub, 1a are cutter heads, 1b is the cutting face, the 2nd, connect taper shank, the 3rd, knife bar, the 4th, workpiece, the 5th, chamfered bore, the 6th, drill press spindle.
The specific embodiment
Through the specific embodiment and above accompanying drawing the utility model is further specified below.Embodiment is used to explain the utility model, limits the utility model never in any form.
In conjunction with Fig. 1 to Fig. 3.
Reverse chamfering tool comprises connecting taper shank 2, knife bar 3 and chamfering cutter hub 1 that the cutter head 1a cross-sectional area on chamfering cutter hub 1 top is greater than knife bar 3 cross-sectional areas, and cutter head 1a and knife bar 3 linkage section outer surfaces form the cutting face 1b of inclination.
Connecting taper shank 2 is top bullets less than the middle part, and the rectangle fixed block is arranged at the top.
Existing chamfering tool is used for the top chamfering to Workpiece boring, its connect taper shank directly with the main shaft of drilling machine form connects after, need normal feed can accomplish chamfering.But need chamfering and can not accomplish can't it be inverted the time for the below in and hole big when workpiece.
The utility model chamfering tool changes machine direction and realizes reverse chamfering through utilizing chamfering tool commonly used that the original direction of its cutter hub is made amendment.When using above-mentioned reverse chamfering tool, earlier workpiece 4 clampings are put in place, connection taper shank 2 one ends of chamfering tool are passed needs chamfered bore 5 again, is connected on the main shaft 6 of drilling machine, and after installing, chamfering cutter hub 1 just can carry out chamfering to chamfer site.
Claims (2)
1. reverse chamfering tool; Comprise and connect taper shank (2), knife bar (3) and chamfering cutter hub (1); It is characterized in that: cutter head (1a) cross-sectional area on said chamfering cutter hub (1) top is greater than knife bar (3) cross-sectional area, and cutter head (1a) forms the cutting face (1b) of inclination with knife bar (3) linkage section outer surface.
