Utility model content
The utility model is for avoiding the existing weak point of above-mentioned prior art, provides a kind of simple in structure, easy to use and safeguard, can reduce the cylinder times travel prolongation mechanism of equipment investment and use cost.
The utility model is that technical solution problem adopts following technical scheme:
The design feature of the utility model cylinder times travel prolongation mechanism is: the translation direction according to slide unit on fixed pedestal arranges Rodless cylinder, a side at described Rodless cylinder, with the translation direction of described slide unit first tooth bar that be arranged in parallel, in one end of described Rodless cylinder, be fixedly installed a pinion stand, a rotating gear is set in described pinion stand; On described fixed pedestal, be provided with the supporting track parallel with the translation direction of described slide unit; Slide unit is supported on the supporting track of described fixed pedestal, and can move along described supporting track, in the bottom surface of described slide unit, be fixedly installed the second tooth bar, described gear is meshed with described the first tooth bar and the second tooth bar simultaneously, and described the first tooth bar and the second tooth bar are formed to reverse each other transmission.
The design feature of the utility model cylinder times travel prolongation mechanism is also:
Described supporting track is left side rail and the right side rail that is fixedly mounted on described fixed pedestal and is parallel to described the first tooth bar, described slide unit be the left side roller that arranges with correspondence and right side roller supporting in described left side rail and right side rail, form guiding mechanism.
Described left side rail is hexagon guide rail, and described right side rail is square rail; The wheel rim of the corresponding left side roller arranging is to match with hexagon guide rail, and to limit the axial float of left side roller, described right side roller is cylindrical roll.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model is to provide driving force by cylinder, without other power, environment friendly and pollution-free except high-pressure air source;
2, the utility model can guarantee result of use, can significantly reduce again equipment cost, reduce maintenance cost; It is simple, convenient;
3, the utility model is when slide unit displacement is longer, and the stroke of Rodless cylinder need be only half of slide unit displacement.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation figure;
Fig. 2 is fixed pedestal structural representation in the utility model;
Fig. 3 is slide unit structural representation in the utility model;
Fig. 4 is that in the utility model, slide unit moves and reaches another location schematic diagram;
Fig. 5 is the utility model principle schematic;
Number in the figure: 1 fixed pedestal, 2 left side rail, 3 right side rail, 4 first tooth bars, 5 pinion stands; 6 gears, 7 Rodless cylinders, 8 first limited blocks, 9 slide units, 10 second tooth bars, 11 left side rollers, 12 right side rollers, 13 second limited blocks.
The specific embodiment
Referring to Fig. 1, in the present embodiment, the version of cylinder times travel prolongation mechanism is: on fixed pedestal 1, according to the translation direction of slide unit 9, Rodless cylinder 7 is set, a side at Rodless cylinder 7, with slide unit 9 translation directions first tooth bar 4 that be arranged in parallel, in one end of Rodless cylinder 7, be fixedly installed a pinion stand 5, a rotating gear 6 is set in pinion stand 5; On fixed pedestal 1, be provided with the supporting track parallel with the translation direction of slide unit 9; Slide unit 9 is supported on the supporting track of fixed pedestal 1, and can move along supporting track, in the bottom surface of slide unit 9, be fixedly installed the second tooth bar 10, gear 6 is meshed with the first tooth bar 4 and the second tooth bar 10 simultaneously, and the first tooth bar 4 and the second tooth bar 10 are formed to reverse each other transmission.
In concrete enforcement, as shown in Figures 2 and 3, supporting track is left side rail 2 and the right side rail 3 that is fixedly mounted on fixed pedestal 1 and is parallel to the first tooth bar 4, and slide unit 9 is to be supported in left side rail 2 and right side rail 3 with the left side roller 11 of correspondence setting and right side roller 12, forms guiding mechanism.
For accurate guiding, by left side rail 2, be hexagon guide rail, right side rail 3 is square rail; The wheel rim of the corresponding left side roller 11 arranging is to match with hexagon guide rail, to limit the axial float of left side roller 11, guarantees that slide unit 9 direction along ng a path rectilinear motions do not depart from, and right side roller 12 is cylindrical roll, is to roll and coordinate on square rail.
In addition, in order to make slide unit 9 obtain precise positioning on fixed pedestal 1, front end at fixed pedestal 1 is fixedly installed the first limited block 8, front end correspondence at slide unit 9 arranges the second limited block 13, when slide unit 9 moves to position as shown in Figure 4, the first limited block 8 and the second limited block 13 are inconsistent, realize the spacing control that puts in place.
In concrete enforcement, fixed pedestal 1 is the BASE substrate on pipeline, after Rodless cylinder 7 ventilations, 5 translations of cylinder slide block driven gear seat, gear 6, along with pinion stand 5 moves, meanwhile, carries out engaged transmission with the first tooth bar 4 and the second tooth bar 10 respectively by gear 6.
As shown in Figure 5, according to movable pulley principle, in a flash in office, gear centre B and gear and carry-over bar point of contact A be take fulcrum O as centre of gyration rotation, and the instantaneous angular velocity ω that A point is ordered with B is identical, now, and the linear velocity V that A point and B are ordered
aand V
bdirection is parallel with orbital direction, that is: V
a=2 ω R; V
b=ω R, therefore V
a=2V
b, hence one can see that, in same time t, and the distance S that A point is mobile
ab point displacement S
btwice, also: S
a=2S
b.
Hence one can see that, and stockless cylinder slipper travel distance is half of slide unit travel distance, also can use the Rodless cylinder of short stroke to realize the sliding distance that doubles cylinder stroke.
