Fig. 2 is the right view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
As Fig. 1, shown in 2, the adjustable automatically accurate reversing arrangement of mechanical type of the present utility model, comprise commutation board 1, reversing shaft 2, handle knob 3, commutation latch 4, spring 5, clamping lever 6, clamp 7, support 8, commutation collision block 9, travel switch 10, the first to the 3rd rotating disk 11,12,13, pull pin 14, gear wheel 15, gear 16, latch (17), hold out against spring 18, small worm 19 and relevant driving-chain etc.
In the middle of reversing shaft 2, four latch grooves are arranged, four commutation latches 4 are housed, every commutation latch 4 ends are equipped with a radially latch 17, hold out against with holding out against spring 18, can drive gear wheel 15 or three rotating disk 11 motions after ejection.Commutation latch 4 use springs 5 are pressed on 3 end faces of handling knob, and 3 end faces of handling knob have a groove, guarantee to only have a commutation latch 4 to eject at every turn, and outer surface corresponding to groove location has groove.There is scale on commutation board 1 surface, and the total travel length quartering is labeled on commutation board 1.Gear wheel 15 of suit and the first to the 3rd rotating disk 11,12,13 on reversing shaft 2.Gear wheel 15 axis holes have a keyway.Opening in the first to the 3rd rotating disk 11,12,13 axis holes all has a keyway, and end face is opened and had a angle the arc groove of 265 ° simultaneously.Input driving-chain and gear wheel 15 need to calculate speed ratio, and when guaranteeing non-Digit Control Machine Tool planker or moving-member operation 1/4 stroke, gear wheel 15 turns over 265 ° of angles.Between gear wheel 1 and each rotating disk with 14 transmissions of pulling pin.Small worm 19 is used for finely tuning two distances between commutation piece 9.Fix by clamping lever 6, clamp 7, support 8 after adjusting to the right place.
When for example planker total travel 12m used, the groove on 3 of handling knob aimed at that on commutation board 1, " 3m " locates, and one of them latch 17 inserts in gear wheel 15 keyways, by transmission system result of calculation, moving-member moves 3m, and so 265 ° of gear wheel 15 revolutions are commutation board 1 that is turn round 265 °.Groove aims at that on commutation board 1, " 6m " locates on 3 if will handle knob, at this moment first latch 17 withdraws from keyway, second latch just inserts in the 3rd rotating disk 13 keyways, when planker moves front 3m, is the arc groove of 265 ° owing to having an angle in the 3rd rotating disk 13,14 is inoperative so begin to pull pin, 265 ° of gear wheel 15 idle running, when planker moved rear 3m, pulling pin 14 could drive 265 ° of the 3rd rotating disk 13 rotations, so commutation board 1 also only turns round 265 °, and the planker traveled distance is 6m.Groove aims at that on commutation board 1, " 9m " locates on 3 if will handle knob, and second latch that is withdraw from the 3rd rotating disk 13 keyways is just the 3rd latch inserts in the keyway of the second rotating disk 12.Be the arc groove of 265 ° and have equally an angle in the 3rd rotating disk 13, so when planker moves front 6m, gear wheel 15 namely dallies 2 * 265 °, when mobile last 3m, pull pin and 14 could drive the second rotating disk 12 and rotate 265 °, so commutation board 1 still only turns round 265 °, and the planker traveled distance has reached 9m.Same reason, on commutation board 1, " 12m " locates when the groove of handling knob on 3 is aimed at, and under the 4th latch and the effect of pulling pin, the planker traveled distance reached in the situation of 12m, and commutation board 1 still turns round 265 °.No matter planker in what travel range, forwards corresponding position to as long as adjust 3 grooves of handling knob like this, then adjusts commutation collision block 9 corner dimensions, can obtain the needed commutation stroke of planker.The commutation precision guarantees by frame for movement, and small worm 19 is used for finely tuning two distances between commutation piece 9.
