Abstract

The utility model discloses a kind of taper mill anti-receding device, comprise knife bar cover, taper knife bar, supporting ring, nut, flat key, described supporting ring is fixedly connected with knife bar cover, nut is flexibly connected with supporting ring, conical surface inner chamber and the knife bar male cone (strobilus masculinus) of knife bar cover match each other, taper knife bar is provided with keyway, and flat key mates mutually with keyway.The utility model can, by milling cutter fixation, prevent milling cutter from occurring the phenomenon of automatic withdrawal when keyseat, guarantees that keyseat is once just processed qualified, improves operating efficiency, also reduce cost simultaneously.

Description

A kind of taper mill anti-receding device
Technical field
The utility model relates to Machining Technology field, particularly relates to a kind of taper mill anti-receding device.
Background technology
Milling machine is very extensive in mechanical processing industry application, milling machine carrying out milling, bore and add man-hour, in machine tool chief axis hole, milling cutter or drill bit to be installed, locate by the latching characteristics of changable sleeve, step up between the knife bar of cutter and machine tool chief axis endoporus, realize transmitting torque, the function of cutting workpiece.Equipment, after use for many years, due to frequent dismounting cutter, causes machine tool chief axis hole and sleeve to occur certain wearing and tearing, and then reduces coupling mechanism force between the two.When keyseat, because knife bar is fixing loosely, have the generation of automatic withdrawal phenomenon, result causes the keyway degree of depth to be deepened gradually, causes keyway defective, needs again to process, reduces operating efficiency, improve production cost.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, designs a kind of taper mill anti-receding device, solves the problem that cutter bar of milling cutter exits automatically.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of taper mill anti-receding device, comprise knife bar cover, taper knife bar, supporting ring, nut, flat key, described supporting ring is fixedly connected with knife bar cover, nut is flexibly connected with supporting ring, conical surface inner chamber and the knife bar male cone (strobilus masculinus) of knife bar cover match each other, taper knife bar is provided with keyway, and flat key mates mutually with keyway.
Described nut is round nut, and the internal thread of round nut mates mutually with the external screw thread of supporting ring.
Described supporting ring is welded on knife bar and puts.
Described keyway is at least two, is evenly distributed in circumferentially whole.
Positive beneficial effect: the utility model, by milling cutter anti-receding device, can, by milling cutter fixation, prevent milling cutter from occurring the phenomenon of automatic withdrawal when keyseat, guarantee keyseat once just process qualified, phenomenon of doing over again can not be there is again, improve operating efficiency, also reduce cost simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
The concrete meaning of number in the figure is: 1 is taper knife bar, and 2 is supporting ring, and 3 is nut, and 4 is knife bar cover, and 5 is flat key, and 6 is keyway.
Detailed description of the invention
Embodiment one, see Fig. 1, a kind of taper mill anti-receding device, comprise knife bar cover 4, taper knife bar 1, supporting ring 2, nut 3, flat key 5, described supporting ring 2 and knife bar overlap 4 and are fixedly connected with, and nut 3 is flexibly connected with supporting ring 2, and conical surface inner chamber and knife bar 1 male cone (strobilus masculinus) of knife bar cover 4 match each other, taper knife bar 1 is provided with keyway 6, and flat key 5 mates mutually with keyway 6.
Described nut 3 is round nut, and the internal thread of round nut mates mutually with the external screw thread of supporting ring 2.
Described supporting ring 2 is welded on knife bar cover 4.
Described keyway 6 is at least two, is evenly distributed in circumferentially whole.
During use, taper knife bar 1 is inserted knife bar cover 4, round nut 3 is installed and pushes down knife bar 1, thus knife bar 1 is fixed in knife bar cover 4.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the field have been to be understood that; Still can modify to detailed description of the invention of the present utility model or equivalent replacement is carried out to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope of the utility model request protection.
