Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is further described.
As it is shown in figure 1, the swollen lever fixing apparatus of electric tube expander, including expander roll assembly, stand-by expander roll mechanism, work expander roll mechanism and expander roll dismounting movable plate 1.
Expander roll assembly includes expander roll 6, expander roll fixed cover 12 and elastic ferrule 13, and its assembly relation is as shown in Figure 6.
Elastic ferrule 13 is as shown in Figure 7, elastic ferrule 13 shell arranges the upper shed gap 1301 of four deciles, the through hole 1303 just allowing expander roll to pass through is had in the middle of elastic ferrule 13, expander roll is through being clamped by the upper shed gap 1301 on top after elastic ferrule 13 and fixing expander roll again, so more convenient and clamp securely or unclamp expander roll.
Expander roll fixed cover 12 is enclosed within outside elastic ferrule 13, elastic ferrule 13 upper shed gap 1301 folder is held together, thus being fixed on elastic ferrule 13 by expander roll 11, work expander roll 11, expander roll fixed cover 12 and elastic ferrule 13 are integral, and work expander roll 11 would not be deviate from from elastic ferrule 13.
Stand-by expander roll mechanism includes Magnet cover plate 2, link plate 3, stand-by expander roll jam plate 4, jam plate supporting plate 5, Magnet 7.
Together with above-mentioned link plate 3 is vertically fixed on jam plate supporting plate 5, stand-by expander roll jam plate 4 is slidably disposed between link plate 3 and jam plate supporting plate 5, and is held by jam plate supporting plate 5, as shown in Figure 2.
Being respectively provided with two through holes 31 holding expander roll assembly on link plate 3, each through hole 31 top arranges Magnet 7, expander roll 6 when Magnet 7 can attract dormant state and make expander roll not drop.
Arranging expander roll lockhole 40 on stand-by expander roll jam plate 4, expander roll lockhole 40 includes the macropore 401 and the aperture 402 that link together, and macropore 401 allows expander roll assembly to pass through, and aperture 402 just blocks expander roll, sees Fig. 8.
Mobile stand-by expander roll jam plate 4, when macropore 401 is relative with expander roll assembly, just can make expander roll assembly by macropore 401, thereby through expander roll jam plate 4.When aperture 401 is relative with expander roll assembly, the expander roll of expander roll assembly is blocked by aperture 401, and expander roll is just lockable.
Magnet cover plate 2 covers on link plate 3, and the hole holding Magnet 7 may also be arranged on Magnet cover plate 2.
Why stand-by expander roll mechanism arranges Magnet 7, it is therefore intended that after preventing expander roll jam plate from unclamping, and stand-by expander roll assembly can drop downwards because of own wt, it is prevented that occur hurting sb.'s feelings or the generation of part of damage event.
Work expander roll mechanism is arranged on immediately below stand-by expander roll mechanism, and it includes upper cover plate 8, work expander roll jam plate 9, lower cover 10, and upper cover plate 8 and lower cover 10 are fixed together, and arranges moveable work expander roll jam plate 9 between upper cover plate 8 and lower cover 10.
Upper cover plate 8 arranges two through holes 81 allowing expander roll assembly to pass through, lower cover 10 correspondence position arranges two through holes 101, through hole 101 is up big and down small, bottom arranges limited step 1001, through hole 101 allows expander roll assembly to move up, but when expander roll assembly is downward, the expander roll fixed cover of expander roll assembly can limited step 1001 stop and not still further below.
Work expander roll jam plate 9 is similar to stand-by expander roll jam plate 4, can referring to the foregoing description of stand-by expander roll jam plate 9, and the expander roll jam plate 9 that works can unclamp or pin expander roll during duty, not described in detail herein.
Work expander roll lower cover 10 bottom surface arranges guiding bar 14, and expander roll dismounting movable plate 1, by guiding bar 14 to guide, expander roll dismounting movable plate 1 arranges the through hole 11 allowing expander roll 11 to pass through.
As in figure 2 it is shown, after expander roll adjusts when stand-by expander roll and work, move stand-by expander roll jam plate and work expander roll jam plate respectively, by stand-by expander roll and work expander roll locking, so during work, stand-by expander roll assembly and the expander roll assembly that works will not plaies up and down.
As shown in Figure 3, if need to by expander roll by stand-by convert work expander roll to time, first work expander roll jam plate and stand-by expander roll jam plate are unclamped, again the expander roll assembly of dormant state is dropped downwards, until the expander roll fixed cover lower surface of expander roll assembly of dormant state touches the hole step 1001 of work expander roll lower cover 10 and spacing, as shown in Figure 4, now the expander roll of dormant state converts duty to, and expander roll assembly is locked by then work expander roll and stand-by expander roll jam plate again.
In like manner, it is also possible to convert the expander roll of duty to dormant state, first work expander roll jam plate and stand-by expander roll jam plate are unclamped, then by work expander roll assembly upwardly, until expander roll is fixedly sleeved contacts Magnet 7.
As shown in Figure 5, when work expander roll pulled down by needs, work expander roll jam plate is locking state, expander roll dismounting movable plate 1 is by driving being driven up of element, withstand elastic ferrule 13, now can drag downwards work expander roll, owing to elastic ferrule 13 is elastomer, so work expander roll is dragged downwards and just can be removed.Insert expander roll on the contrary and be pushed up just can loading onto expander roll.When tearing stand-by expander roll open, first convert stand-by expander roll to work expander roll, then repeat the step of work expander roll above.
