Scope.
As shown in Figure 1, Figure 2, Figure 3 shows, the utility model provides a kind of lathe handle of a knife conversion equipment, including taper conversion sleeve 1
It is communicated and is constituted by cylindrical hole 4 and taper hole 5 with the axis hole of the blind rivet 2 in taper conversion sleeve, taper conversion sleeve 1, cylindrical hole 4
In the small end of taper conversion sleeve 1, taper hole 5 is located at the big end of taper conversion sleeve 1, and the big end end face of taper conversion sleeve 1 is equipped with several
A circumferential direction is uniformly distributed and is used for the mounting hole 3 of connecting machine tool main shaft；Blind rivet 2 is threaded through in the cylindrical hole, and blind rivet 2 is for connecting
One end of handle of a knife 6 is located in taper hole, and the other end of blind rivet 2 is used for connecting machine tool main shaft and exposes to the small end of taper conversion sleeve 1
Outside, and the maximum outside diameter of blind rivet 2 be less than cylindrical hole 4 internal diameter.In the present embodiment, because the maximum outside diameter of blind rivet 2 is less than
The internal diameter of cylindrical hole 4, so entire blind rivet 2 can pass freely through cylindrical hole 4.Therefore, in the feelings for not dismantling taper conversion sleeve 1
Under condition, handle of a knife 6 can be extracted out out of taper conversion sleeve 1 axis hole together with related blind rivet 2, to the new handle of a knife that conveniently changes the outfit, save
Assembly time improves whole processing efficiency.
When referring to Fig.1, using above-described embodiment, taper conversion sleeve 1 is assembled on machine tool chief axis (i.e. taper conversion first
The male cone (strobilus masculinus) of set 1 is bonded with the inner conical surface of machine tool chief axis), and taper conversion sleeve 1 is fastened to by machine tool chief axis by mounting hole 3
On.Furthermore one end of blind rivet 2 is connected with handle of a knife 6.Then, the other end of blind rivet 2 sequentially passes through taper hole 5 and cylindrical hole 4, until
It extend out to outside the small end of taper conversion sleeve 1.Then, the claw in machine tool chief axis clamps the ailhead of blind rivet 2 and to the left
It tenses, the inner conical surface of the male cone (strobilus masculinus) and taper hole 5 of handle of a knife 6 is made to fit closely.When need to change the outfit new handle of a knife when, as long as unclamp lathe master
The claw of axis, blind rivet 2 can be detached directly out of taper conversion sleeve 1 axis hole, so as to which reliable, quickly change the outfit new knife
Handle.Above-described embodiment is simple in structure, easy to operate, easily controllable.
Specifically, taper conversion sleeve 1 has the ISO60 male cone (strobilus masculinus)s being bonded with machine tool chief axis, and its taper hole 5 has and knife
The ISO50 inner conical surfaces that handle 6 is bonded, thus it is suitable for all machine tool chief axis with BT60 interfaces.Taper conversion sleeve 1 can pass through
The bolt or screw that are located in mounting hole 3 are fastened with machine tool chief axis, to reduce the taper hole of machine tool chief axis because of cutting force (or taper
The dead weight of conversion sleeve 1) and the Influence from Eccentric that is subject to, the taper hole of machine tool chief axis is protected to the maximum extent, ensure that machine tool chief axis
Precision meets machine tooling requirement.
In order to reduce the specification of taper conversion sleeve 1, there are two types of the tools of above-mentioned blind rivet 2 specification, i.e. BT50 blind rivets and ST50 blind rivets,
Different handle of a knifes 6 is installed by using the blind rivet of different size.With reference to Fig. 4, the total length L of BT50 blind rivets is 164.5mm, nail
The length W of tail is 33.7mm, and the total length L of ST50 blind rivets is 148.8mm, and the length W for following closely tail is 37.5mm.As shown in figure 5,
The nail tail 21 of BT50 blind rivets is connected on BT50 handle of a knifes 61；As shown in fig. 6, the nail tail 22 of ST50 blind rivets is connected to ST50 handle of a knifes 62
On.
Since the frequency that blind rivet 2 wears taper conversion sleeve 1 is higher, blind rivet 2 has the smooth circle being placed in above-mentioned cylindrical hole
Shell of column, to reduce the friction between blind rivet 2 and cylindrical hole 4.
Handle of a knife 6 is connected in order to facilitate the nail tail of blind rivet 2, one end that blind rivet 2 is used to connect handle of a knife 6 has thread segment.
In order to which more preferably taper conversion sleeve 1 is fastened on machine tool chief axis, the big end of taper conversion sleeve 1 has flange ring, Gu
Determine hole 3 be located on flange ring and quantity be four.
In addition, the big end periphery of above-mentioned taper conversion sleeve 1 is equipped with transmits torque for machine tool chief axis to taper conversion sleeve 1
Two keyways 7, two keyways 7 be located at it is same diametrically.The big end end face of taper conversion sleeve 1 be equipped with for taper conversion sleeve 1 to
Handle of a knife 6 transmit torque two straight end-face keys 8, two straight end-face keys 8 be located on same circumference and be located at it is same diametrically.
In conclusion the utility model is in the case where dismantling taper conversion sleeve, handle of a knife can with related blind rivet together from
Extraction in the axis hole of taper conversion sleeve saves assembly time, improves whole processing efficiency to the new handle of a knife that conveniently changes the outfit.Institute
With the utility model effectively overcomes various shortcoming in the prior art and has high industrial utilization.
The above embodiments are only illustrative of the principle and efficacy of the utility model, new not for this practicality is limited
Type.Any person skilled in the art can all carry out above-described embodiment under the spirit and scope without prejudice to the utility model
