The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done to describe in further detail.
Fig. 1 is a kind of accurate centering positioning device structure sketch map.As shown in Figure 1; This device comprises connecting gear (among the figure for being with 1 synchronously); Clamping mechanism (comprise planker 1, guide post 1, interior guiding pole socket 4 and 18, slide block 1, benchmark centering locating piece 8, non-benchmark centering piece 13, slide block 2 14, guide post 2 15, the pole socket 16 and 17 that leads) outward; Delay mechanism's (comprising planker 29, steady pin 10, fulcrum post 11), detent mechanism (being backstop 7 and opposite side backstop among the figure).Said connecting gear can be flexible band (no cingulum, multiple tooth band, synchronous band, a chain etc.); Also can be tooth bar and the symmetrical linkage of installing that symmetry is laid; Its effect provides power, drives the centering locating piece and moves along track, and said track can be straight line or arcuate version.The said mechanism of delaying can be that gapped hole axle cooperates or the partial gear group, and its effect is that connecting gear is delayed in the constantly non-benchmark locating piece generation of first motion displacement.Said adjusting retaining mechanism rigidity is adjustable, and regulative mode can be screw thread or wedge or piezoelectric ceramics, and its effect is with each locating piece set positions accurately and be fixed up.The effect of said clamping mechanism is benchmark centering locating piece 8, non-benchmark centering piece 13 positioning fixture or workpiece under the guide effect of guide post 1, guide post 2 15.
After anchor clamps are in place, be with 1 to drive planker 1 and planker 29 and move synchronously along center position; When dextrad moves shown in the direction of arrow in figure with planker one 2 rigidly connected slide blocks 1; The adjusting rod 1 that is fixed in slide block 1 contacts with backstop 7; Apply on the magnetic locking slide block 1 this moment, and direction is pointed to anchor clamps, thereby guarantee that benchmark centering locating piece 8 is on desired location.Simultaneously, planker 29 is when left-hand moves shown in the direction of arrow in center position is promptly schemed, and has the gap owing to be rigidly secured to the steady pin 10 of slide block 2 14 with hole on the planker 29, advances thereby after postponing a bit of distance, could drive slide block 2 14 diagram left sides.When band stop motion synchronously, when applying locking magnetic force on slide block 2 14, and direction points to anchor clamps, thereby after traction slide block 2 14 compensates a bit of distance left, realizes contacting of adjusting rod 12 and backstop.Thereby realize that anchor clamps or workpiece are positioned on the accurate position between locating piece.
Fig. 2 is for delaying the mechanism structure sketch map.When planker 29 when direction shown in Figure 1 moves, first wraparound is shipped and resell on another market and 11 is rotated and cause slide block 14 shown in Figure 1 to delay a section and move.And when connecting gear was rigid toothed, fulcrum post 11 can be cancelled.
Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the present invention; And be not to be used as qualification of the present invention; As long as in connotation scope of the present invention, the above embodiment is changed, modification all will drop in the scope of claims of the present invention.
