Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Fig. 1 shows the turning device of the utility model embodiment and the structural representation of turnover driving mechanism 100 thereof, and Fig. 2 shows the cutaway view of wherein turnover driving mechanism 100, and Fig. 3 shows the lateral plan of wherein turning device entirety.As shown in figures 1 and 3, this turning device comprises two the first cant boards 201 be oppositely arranged and the second cant board 202 and is installed on the upset material folding arm 300 between the first cant board 201 and the second cant board 202 respectively by the first trip shaft 401a and the second trip shaft 401b, the turnover driving mechanism 100 also comprising driving first trip shaft 401a and then drive upset material folding arm 300 to rotate.
Specifically as depicted in figs. 1 and 2, turnover driving mechanism 100 is formed primarily of driver element 10, guide rail 30, tooth bar 20 and gear 40, driver element 10 drives tooth bar 20 to slide along guide rail 30, and then to drive and tooth bar 20 gears in mesh 40 rotates, gear 40 is fixedly connected with (see Fig. 3) with the first trip shaft 401a thus drives the first trip shaft 401a and then drive to overturn together with material folding arm 300 and rotates.Further as depicted in figs. 1 and 2, driver element 10 is formed primarily of drive motor 11, screw mandrel 14 and feed screw nut 17, drive motor 11 drives screw mandrel 14 to rotate, and then driving the feed screw nut 17 be loaded on screw mandrel 14 to move along the direction parallel with guide rail 30, tooth bar 20 is fixedly connected with feed screw nut 17 and then is driven by feed screw nut 17 and slides along guide rail 30.Wherein, drive motor 11 is fixedly mounted on motor mounting plate 12, and motor mounting plate 12 is fixed on the first cant board 201 top.The rotating shaft of drive motor 11 is connected with the end of the first end of screw mandrel 14 by coupler 13.The first end of screw mandrel 14 is installed in the first screw mandrel bearing 151 on the first screw mandrel supporting seat 15 and to be undertaken on axial direction by the first screw mandrel jam nut 152 spacing fixing, screw mandrel 14 can only be rotated, movement axially can not occur.Equally, the second end of screw mandrel 14 is installed in the second screw mandrel bearing 161 on the second screw mandrel supporting seat 16 and to be undertaken on axial direction by the second screw mandrel jam nut 162 spacing fixing, screw mandrel 14 can only be rotated, movement axially can not occur.First screw mandrel supporting seat 15 and the second screw mandrel supporting seat 16 are all fixed on the first cant board 201.Feed screw nut 17 coordinates with screw mandrel 14, the moving axially along screw mandrel 14 with the rotation of screw mandrel 14.Feed screw nut 17 is also fixedly connected with a nut contiguous block 18, the other end of this nut contiguous block 18 and then be fixedly connected with a plate 19.Connecting panel 19 fit that slides is installed on guide rail 30, is fixedly installed on connecting panel 19 with hour rack 20.Such tooth bar 20 just links with feed screw nut 17, and tooth bar 20 slides along guide rail 30 along the movement of screw mandrel 14 with feed screw nut 17.Gear 40 engages with tooth bar 20, thus rotates along the slip of guide rail 30 with tooth bar 20.
Further as depicted in figs. 1 and 2, this driving switching mechanism 100 is also provided with the first position-limiting unit controlling drive motor 11 and work, and this first position-limiting unit comprises sensing chip 181 and the upper inductor 80a that coordinates with sensing chip 181 and lower inductor 80b.Sensing chip 181 is fixedly mounted on nut contiguous block 18, can move with feed screw nut 17.Upper inductor 80a and lower inductor 80b is arranged on the first cant board 201 in the corresponding gap slot 211 offered respectively, and adjusts two inductors in gap slot 211 along the position on screw mandrel axial direction by governing screw 81.When drive motor 11 drives screw mandrel 14 to drive feed screw nut 17 to be moved downward to the position of the lower inductor 80b of sensing chip 181 triggering, lower inductor 80b sends signal control drive motor 11 and reverses, and drives feed screw nut 17 to move up.When drive motor 11 drives screw mandrel 14 to drive feed screw nut 17 to be moved upward to the position of the upper inductor 80a of sensing chip 181 triggering, upper inductor 80a sends signal control drive motor 11 and rotates forward, and drives feed screw nut 17 to move down.So repeatedly, realize the up and down reciprocatingly slip of tooth bar 20 along guide rail 30, thus realize positive and negative 180 degree of reciprocating rotations of gear 40, drive upset material folding arm 300 to realize 180 degree and back and forth overturn.
Specifically as shown in Figure 3, upset material folding arm 300 is installed between the first cant board 201 and the second cant board 202 respectively by the first trip shaft 401a and the second trip shaft 401b.First trip shaft 401a is installed on the first cant board 201 by the first upset bearing 402a, and is fixedly connected with to rotate with gear 40 with gear 40.Second trip shaft 401b to be installed on the second cant board 202 by the second upset bearing 402b and to carry out axial limiting by bearing gland 403, makes it only rotate under external force, relative movement can not occur.Gear 40 drives the first trip shaft 401a to rotate, thus drives upset material folding arm 300 to rotate together.In preferred embodiment, gear 40 is designed to biplate offset gear, the tooth of the same position of two plate gears adopts the dedendum flank of the addendum flank of a tooth and another one tooth to carry out 0 free-running fit with the teeth groove of tooth bar 20 correspondence respectively, thus it is very close to each other when realizing running, and then the stability realizing operation, start and stop, whole upset steadily, is not rocked, and position is accurate.
Further as shown in Figure 3, this turning device also corresponding the first upset limit position (as shown in FIG.) overturning material folding arm 300 is provided with the first mechanical position limitation block 501, and the second upset limit position of corresponding upset material folding arm 300 is provided with the second mechanical position limitation block 502.State as Figure 1-3, sensing chip 181 is in the position of lower inductor 80b, upset material folding arm 300 is in the first upset limit position of cw upset, it is parallel with conveyor surface that it picks and places charge level, now to carry out mechanical type to upset material folding arm 300 spacing for the first mechanical position limitation block 501, guarantee the accuracy of position, mechanism can not run excessive.Simultaneously, rotate backward at drive motor 11 thus be with by screw mandrel 14 carry-over bar 20 along guide rail 30 up move to sensing chip 181 be in inductor 80a position time, tooth bar 20 driven gear 40 does anticlockwise direction and revolves turnback, arrive anticlockwise direction second and overturn limit position, pick and place charge level parallel with conveyor surface, now to carry out mechanical type to upset material folding arm 300 spacing for the second mechanical position limitation block 502, guarantees the accuracy of position.In different embodiment, if feeding position is arranged in first of clickwise the upset limit position, second upset limit position of corresponding left-hand revolution is then blowing position, otherwise then blowing position is arranged in the first upset limit position of clickwise, the second upset limit position of corresponding left-hand revolution is then feeding position.
In addition, those skilled in the art it is understood that, according in different embodiment of the present utility model, driver element 10 can also be realized by other suitable technological means, the structure such as can slided by driven by motor Timing Belt and then band carry-over bar is realized, or the structure of directly being slided by air cylinder driven tooth bar is realized.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
