Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done explanation in further detail.
Fig. 1 is the sectional view of a kind of self-equilibrating symmetry charger of the present invention, and Fig. 2 is along the cross section view of A-A direction, as shown in the figure among Fig. 1.A kind of self-equilibrating symmetry charger comprises chute support 1, loading slider bracket 2, loads slide block 9, support back-moving spring block 12, loads double-screw bolt 13, loads disk 5, friction disc 4 and handle 18.
Chute support 1 is the U-shaped structure, and the chute opening of the loading slider bracket 2 of U-shaped structure loads that slider bracket 2 is arranged in the chute of chute support 1 and is slidingly matched with the chute of chute support 1 to the right.Loading slider bracket 2 is framed structure, and loading slide block 9 is arranged in the framework that loads slider bracket 2 and with framework and is slidingly matched.Support back-moving spring block 12 is installed in the right part of chute support 1 by socket head cap screw 11, the right-hand member that loads slider bracket 2 stretch out support back-moving spring block 12 and with support back-moving spring block 12 clearance fit.Loading double-screw bolt 13 levels are passed the right-hand member and the support back-moving spring block 12 that load slider bracket 2 from right to left successively and are withstood on the loading slide block 9, load double-screw bolt 13 and the right-hand member clearance fit that loads slider bracket 2, the middle part of support back-moving spring block 12 is provided with threaded hole, loads double-screw bolt 13 and support back-moving spring block 12 threaded engagement.Load the glide direction of slider bracket 2 chute support 1 in, load slide block 9 in loading slider bracket 2 glide direction and the axis of loading double-screw bolt 13 on same horizontal direction.Load on the inboard left side with loading slide block 9 of the left end of slider bracket 2 corresponding arc groove be set respectively, about two arc grooves be oval structure.Load that the left end of slider bracket 2 is inboard to be respectively equipped with slide block back-moving spring 3 with the both sides up and down that load between the slide block 9 and be positioned at arc groove, an end of slide block back-moving spring 3 is pressed in the left end inboard that loads slider bracket 2, and the other end is pressed on the loading slide block 9.Between the left end of loading slider bracket 2 and the inwall in chute support 1 left side support back-moving spring I 6 is set.Load between slide block 9 and the support back-moving spring block 12 support back-moving spring II 10 is set, support back-moving spring II 10 is enclosed within and loads on the double-screw bolt 13.
Load disk 5 and be arranged in two arc grooves, load disk 5 upper edge axis and be provided with and axle 8 mounting holes that cooperate to be measured, axle 8 to be detected is installed in the mounting hole that loads disk 5 by key 7.Friction disc 4 is enclosed within on the cylindrical that loads disk 5, and the cylindrical of friction disc 4 is corresponding with arc groove.When loading, the loading slider bracket 2 in left side and the loading slide block 9 on right side from about when simultaneously axle 8 being clamped, at first contact with friction disc 4, both can reach axle 8 has evenly been loaded, can play a part to protect spools 8 again.
When using this a kind of self-equilibrating symmetry charger, the axle 8 that at first will band detects be installed in by key 7 in the mounting hole that loads disk 5, axle 8 pass end suit upper gasket 19, and lock by hold-down nut 20.
This device load the time, clockwise rotate handle 18, make to load double-screw bolt 13 to left movement, load slide block 9 and in the groove that loads slider bracket 2, slide left thereby make; Simultaneously owing to load double-screw bolt 13 and in the threaded hole of support back-moving spring block 12, advance to left-handed, chute support 1 loads double-screw bolt 13 relatively and moves right, 6 pairs of loadings of support back-moving spring I slider bracket 2 applies spring force to the right, load slider bracket 2 and slide to the right under the spring force effect of support back-moving spring I 6, slide block back-moving spring 3 is compressed.Load slide block 9 like this and load slider bracket 2 and just can be simultaneously will load disk 5 clampings simultaneously from the right and left of loading disk 5 that friction disc 4 is installed, fix with 15 pairs of positions that load double-screw bolt 13 of set nut then, prevent to load double-screw bolt 13 and slide to the right, reach the effect that zero moment of flexure loads symmetrically and evenly.
In unloading, rotate counterclockwise handle 18, loading double-screw bolt 13 is moved right, because the time slide block back-moving spring 3 that loads is compressed, load slide block 9 and load slider bracket 2 under the effect of the restoring force of slide block back-moving spring 3, loading slide block 9 slides to the right, loading slider bracket 2 slides left, like this will compressed stent back-moving spring I 6 and support back-moving spring II 10, make and load slide block 9 and load the effect that slider bracket 2 is subjected to an elastic force respectively, the elastic force of this power and slide block back-moving spring 3 is cancelled out each other, and gets back to original position thereby make to load slide block 9 and load slider bracket 2, has realized that finally charger self-equilibrating zero moment of flexure evenly unloads.Self-equilibrating mainly realizes by four springs.
Explanation is at last, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from the aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
