Abstract
A short Morse taper interface for a modular boring cutter comprises a convex cone and a concave cone. The short Morse taper interface for the modular boring cutter is characterized in that the convex cone is disposed inside the concave cone; a locking ring for an internal tightening bolt is arranged at the center of the concave cone; the end of the tightening bolt is connected with the central hole of the convex cone through screw threads. The small ends of the convex cone and the concave cone are in interference fit and the big ends are in clearance fit and the minimum clearance is 0. Taper holes with cone-shaped ends are arranged at the sides of the concave cone and the internal locking ring, and bolts tightly propping up the internal cone-shaped ends of the taper holes are arranged inside the taper holes, with the conical surfaces at the ends closely contacting with the conical surfaces of the taper holes. The short Morse taper interface for the modular boring cutter has the advantages that based on self-centering principle of conical surface matching, the short Morse taper interface for the modular boring cutter ensures the accuracy of connection concentricity and total contact of the head faces and meanwhile satisfies high requirements of connection accuracy and rigidity and improves the repeated installation precision of the boring cutter; the short Morse taper interface can be assembled freely according to different processing requirements and is flexible and convenient to use.
Description
Technical field
The utility model belongs to the metal cutting technology field, is specifically related to a kind of short tapered joint mouth of modular boring cutter.
Background technology
Along with the continuous development of Computerized Numerical Control processing technology, old-fashioned monoblock type boring cutter can not be satisfied the demand, the substitute is modular boring cutter miscellaneous.The modular boring cutter promptly is that boring cutter is divided into: a plurality of parts such as basic handle, extension bar, undergauge bar, boring cutter body, then according to concrete processing content (heavy boring, right boring; The diameter in hole, the degree of depth etc.) carry out independent assortment.So not only reduce the quantity of handle of a knife widely, reduced cost, also can corresponding rapidly various processing request, and prolong the life-span of cutter integral body.
Though the modular boring cutter is compared with the integral type boring cutter and is had many advantages, but its each several part need connect by interface, at present the connected mode that generally adopts is the hole axle mode that is connected: (1) side-strengthened: this connected mode only is to have reached fixing purpose, not only the end face of connector can not closely contact, poor rigidity, radial position also can change when compressing, and it is low to connect precision; (2) end face contact: this connected mode end face can reach tight contact, and rigidity increases, but because be matched in clearance between the axle of hole, it is not high equally to connect precision.The hole axle is connected and can has the gap all the time between the hole of mode and the axle, and connecting precision cannot guarantee, can not satisfy the needs of modular boring cutter.
The utility model content
The purpose of this utility model is: the short tapered joint degree of lip-rounding of a kind of novel plug formula boring cutter formula is provided, can reaches high connection precision, high rigidity, high repetition installation accuracy simultaneously.
For achieving the above object, the technical scheme of taking is: the short tapered joint mouth of modular boring cutter, comprise convex cone and concave cone, it is characterized in that: described convex cone places in the concave cone, described concave cone center is equipped with the retaining ring of built-in turnbuckle, and the end of described turnbuckle is threaded with described convex cone centre bore.
The small end of described convex cone and concave cone is an interference fit, holds to movingly greatly, and minimum clearance is 0.
Described concave cone and built-in retaining ring side are equipped with the tapered taper hole in end, and the built-in awl end of described taper hole presses closer screw.Described awl end presses closer the conical surface of screw end and the conical surface close proximity of described taper hole one side.
The utility model has the advantages that: this interface adopts short cone match connected mode, utilize the self-centering principle of cone match, guarantee to connect concentricity precision and contact fully, can satisfy high connection precision simultaneously and be connected rigidity, and improve the repetition installation accuracy of boring cutter with end face; The short tapered joint mouth of modular boring cutter can be according to different processing requests, independent assortment, and use is flexible, convenient, and no matter being used as heavy boring cutter interface still is the interface of fine boring cutter, all can satisfy the demand.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation (nature) of the short tapered joint mouth of axial tension formula;
Fig. 2 is the structural representation (tension) of the short tapered joint mouth of axial tension formula;
Fig. 3 presses closer the structural representation (nature) of the short tapered joint mouth of formula for the side;
Fig. 4 presses closer the structural representation (holding out against state) of the short tapered joint mouth of formula for the side;
Fig. 5 is the local enlarged diagram of A among Fig. 4.
Among the figure, the 1-convex cone; The 2-concave cone; The 3-retaining ring; The 4-turnbuckle; 5-awl end presses closer screw; The 6-taper hole; The 7-conical surface.
The specific embodiment
In order to satisfy different needs, Interface design two kinds of locking modes: a kind of is the formula of axially straining, and is applicable to the connection of general shorter part; A kind of is that the side presses closer formula, is applicable to the connection that is difficult for locking than the long handle center.
Embodiment 1 (axially straining formula)
As depicted in figs. 1 and 2, the short tapered joint mouth of modular boring cutter, comprise convex cone 1 and concave cone 2, it is characterized in that: described convex cone 1 places in the concave cone 2, described concave cone 2 centers are equipped with the retaining ring 3 of built-in turnbuckle 4, and the end of described turnbuckle 4 is threaded with described convex cone 1 centre bore.
The small end of described convex cone 1 and concave cone 2 is an interference fit, holds to movingly greatly, and minimum clearance is 0.
Since the cone angle design of convex cone 1 and concave cone 2 a small deviation, under the nature, when two conical surface small ends have contacted, end face can not contact, and a small gap b (as shown in Figure 1) is arranged, and uses allen wrench turn turnbuckle 4 this moment, reach and apply certain pretightning force, make conical surface small end that the distortion of trace take place, finally convex cone 1 is drawn in the concave cone 2, till both ends of the surface fit tightly (as shown in Figure 2).This method connects rigidity and improves greatly.
Embodiment 2 (side presses closer formula)
On embodiment 1 basis, for being applicable to the connection that is difficult for locking than the long handle center, be equipped with the tapered taper hole in end 6 in the side of described retaining ring 3, described taper hole 6 built-in awl ends press closer screw 5 (shown in Fig. 3～5), because the axis that two awl ends on the axis of two taper holes 6 and the concave cone 2 press closer screw 5 has an offset, when screwing in two awl ends simultaneously when pressing closer screw 5, force retaining ring 3 to move axially, described awl end presses closer the conical surface of screw 5 ends and the conical surface 7 close proximity (as shown in Figure 5) of described taper hole 6 one sides, thereby produce concave cone 2 axial tensions, make conical surface small end that the distortion of trace take place, finally convex cone 1 is drawn in the concave cone 2, both ends of the surface are fitted tightly fully.Fig. 3 and shown in Figure 4 two taper holes 6 are arranged presses closer screw 5 with two awl ends of allen wrench turn simultaneously, and convex cone 1 is drawn in the concave cone 2, till both ends of the surface fit tightly.
