Detailed description of the invention
Referring to figs. 1 to Fig. 6, this utility model is described further, by particular specific embodiment, embodiment of the present utility model being described below, the content that those skilled in the art can be disclosed by this specification understands other advantages of the present utility model and effect easily.
Notice, structure that this specification institute accompanying drawings is drawn, ratio, size etc., the most only in order to coordinate the content disclosed in description, understand for those skilled in the art and read, it is not limited to the enforceable qualifications of this utility model, therefore not there is technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size, under not affecting effect that this utility model can be generated by and the purpose that can reach, all should still fall in the range of the technology contents disclosed in this utility model can be contained；Simultaneously, in this specification cited as " on ", the term such as D score, it is merely convenient to understanding of narration, and it is not used to limit the enforceable scope of this utility model, being altered or modified of its relativeness, changing under technology contents without essence, when being also considered as enforceable category of the present utility model.
Hereinafter by specific embodiment, reconstruction structure of the present utility model will be described in detail.
Referring to figs. 1 to Fig. 6, a kind of tool-broaching mechanism of machining center automatic tool changer, including main shaft 1, it is provided with the handle of a knife 3 of blind rivet 2 and for clamping or unclamp the clamping device of handle of a knife 3, blind rivet 2 is provided with positioner 4, positioner 4 includes limited block 41 and the limited impression 42 being successively set on blind rivet 2, clamping device includes the blind rivet tapered sleeve 5 being fixed in main shaft 1, be set in blind rivet tapered sleeve 5 helps pull a cart 6 and make 6 driving means moved up and down of helping pull a cart, help pull a cart and 6 be provided with several through holes 61, the ball 62 for blocking positioner 4 it is provided with in through hole 61, it is additionally provided with in blind rivet tapered sleeve 5 for ball 62 to the circular cone 51 ejected outside 6 of helping pull a cart.
Automatic tool changer principle: when tool-broaching mechanism needs fixed cutting tool, the positioner 4 of the blind rivet 2 being fixed on handle of a knife 3 is through ball 62, now help pull a cart 6 by the upper shifting of driving means driving, be placed in help pull a cart 6 through hole 61 in ball 62 be pressed against helping pull a cart inside 6 by blind rivet tapered sleeve 5 inwall and being exposed, in now ball 62 is placed on limited impression 42 and limited block 41 is blocked, blind rivet 2 cannot be pulled out, thus realize fixing handle of a knife 3, now, it is interior and bonded to each other with taper head 7 that handle of a knife is placed in taper head 7, when cutter is to work pieces process, handle of a knife is under the effect of tapered sleeve head, do not have the phenomenons such as swing, make cutter the most accurate to the processing of workpiece；When needs unload handle of a knife 3, help pull a cart and 6 moved down by the driving of driving means, when through hole on helping pull a cart moves to circular cone, ball 62 ejects outside 6 to helping pull a cart under limited block 41 extrudes the effect of ball 62, now limited block 41 is no longer blocked by ball 62, the blind rivet 2 being fixed on handle of a knife 3 can unload in 6 from helping pull a cart, thus realizes unclamping handle of a knife 3.Circulate with this, carry out automatic tool changer and to realize cutters different on handle of a knife, workpiece is processed.
Blind rivet in this utility model, blind rivet tapered sleeve, the simple in construction helped pull a cart, easy to process, and its processing cost is low.
Driving means in this utility model can be hydraulic oil cylinder driving, it is also possible to be that motor drives, it is achieved that the tool changing of full-automatic words.
Preferably, in order to ensure the effectiveness that ball 62 works, through hole 61 includes outer aperture 611 and inner orifice 612, the bore in outer aperture 611 is more than the diameter of ball 62, make ball 62 can put into through hole 61 at outer aperture 611, and the bore of inner orifice 612 is less than the diameter of ball 62, and ball 62 can be avoided to roll out at inner orifice 612, add the effectiveness of ball 62 work.The diameter of ball 62 is set more than help pull a cart 6 wall thickness so that blind rivet 2 can be blocked and unclamp by ball 62 effectively, it is achieved the tool-broaching mechanism automatic replacing to handle of a knife 3.
Preferably, in order to increase the stability of tool-broaching mechanism work, main shaft 1 is provided with the fixing groove 11 for placing taper head 7, for placing the tapered sleeve groove of blind rivet tapered sleeve 5 and for the sliding tray 14 slided of helping pull a cart, taper head 7 is interference fit with the cell wall of fixing groove 11, make between taper head 7 and main shaft 1 connect convenient and connect more firm, blind rivet tapered sleeve 5 is interference fit with the cell wall of tapered sleeve groove 12, make blind rivet tapered sleeve 5 and tapered sleeve groove 12 easy to connect and connect more firm, the described gap helped pull a cart between 6 and the cell wall of sliding tray 13 is 0.02mm-0.04mm, if helping pull a cart, the gap between 6 and the cell wall of sliding tray 13 is the biggest, 6 meetings of then helping pull a cart be rocked in sliding tray 13, make to help pull a cart 6 move be not sufficiently stable, so that tool-broaching mechanism work is not sufficiently stable；If helping pull a cart, the gap between 6 and the cell wall of sliding tray 13 is the least, help pull a cart and contain stress with main shaft respectively, gap is the least to be affected it and normally works, additionally add the friction helped pull a cart between 6 and main shaft 1, friction not only increases its power attenuation, making tool-broaching mechanism work be not sufficiently stable, even making to help pull a cart 6 produces abrasion with main shaft 1, reduces its service life.So with gap width be 0.005mm, 0.01mm, 0.02mm, 0.03mm, 0.04mm, 0.05mm, 0.06mm, 0.07mm, 0.08mm carry out experiment obtain as it is shown in fig. 7,
As can be seen from Figure 7, during the scope that the gap between 6 and the cell wall of sliding tray 13 is 0.02mm-0.04mm of helping pull a cart, the optimal stability of tool-broaching mechanism work.
Preferably, more stable in order to make ball run, that taper head 7 is provided with and blind rivet tapered sleeve is adaptive spacing ring 71, this spacing ring 71 prevents ball to helping pull a cart outer side shifting and landing so that ball is maintained in through hole, so that ball is the most stable.
Preferably, in order to make blind rivet 26 put into or withdraw from more smooth and easy from helping pull a cart, arranging limited block 41 and include guide section 411 and lower guide section 412, upper guide section 411 and lower guide section 412 are respectively the conical surface.Helping pull a cart and 6 be internally provided with and limit the limiting plate 63 that moves of handle of a knife 3, limiting plate 63 is used for limiting moving ahead of blind rivet 2, so that blind rivet 2 is put into when helping pull a cart 6 more stable.
Preferably, the number of described through hole 61 is four, and four through holes 61 are uniformly arranged on same circumference, and the positioner 4 on blind rivet 2 can be blocked by four through holes 61 well.
The foregoing is only preferred embodiment of the present utility model, not with the present embodiment for limiting, all any amendment, equivalent or improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
