81.64/5＝16.328
Therefore can reach a conclusion: the clamping speed of the utility model is more than 16～32 times of prior art in this embodiment, can increase work efficiency significantly.
Clamping force instantaneous locked and unclamp principle:
After air bleeding valve 9 was clamped by pressing plate 1 and working panel 2, after guaranteeing to be applied to power on the handlebar head 86 and unclamping, clamping force still remained unchanged, and promptly behind the F1=0, the value of F2 is constant.This function realizes through the interaction relation that drives between locking device 7 and the elastic shaft 6.
The miner diameter end of elastic shaft 6 is fixed on the gear shaft 5 through first axle key 61, and is as shown in Figure 8, and bigger diameter end is fixed on through second axle key 62 and drives on the inner spline 71 of locking device.
As shown in Figure 9, three rollers 74 that circumferentially are uniformly distributed with are in spline 71 and brake disc 76 formed three wedge shape spaces respectively, and under the driving of handle 8, spline 71 can be with elastic shaft 6 freely to clockwise rotate.After clamping workpiece, elastic shaft 6 can not continue freely to clockwise rotate, after the clamping force of clamping work pieces is enough; Elastic shaft 6 forms corresponding deflection; After the release handle, three rollers 74 that circumferentially are uniformly distributed with on the spline are respectively by the elastic thrust effect of three springs that circumferentially are uniformly distributed with 72 and three thimbles that circumferentially are uniformly distributed with 73 at this moment; Withstand roller 74, roller 74 is stuck in the wedge shape dead-centre position of spline and brake disc 76.
As shown in Figure 9:
The coefficient of friction of setting between brake disc 76 and the roller 74 is ξ
Set and consider roller 74 when the wedge shape dead-centre position, stressed angle is illustrated in figure 9 as x °
The power that is applied on the single roller 74 through spline 71 because of elastic shaft 6 distortion is F,
Power F acts on the stress point of brake disc 76 through roller 74, is decomposed into radial component F1 and tangential component F2
F1＝F?*?cos?x°
F2＝F?*?sin?x°
X ° of frictional force f=ξ * F1=ξ * F * cos between roller 74 and the brake disc 76
When f >=F2, roller 74 and be in the nature locking state, under the situation that does not have other external force effects, roller 74 can't prolong counterclockwise and move, and spline 71 also just can't counterclockwise turn round because of roller 74 is in locking state.
This moment is as long as counterclockwise rotate and drive pawl 75, and driving the power that pawl 75 acts on the roller 74 is F3, and when F3+F2 >=f, roller 74 just can leave the wedge shape dead-centre position, removes this locking state rapidly.
According to above principle, just can select suitable material according to drive unit 7 sizes of design, determine suitable coefficient of friction ξ, go out suitable stressed angle x ° of spline 71 according to coefficient of friction ξ calculation Design then.
For example: brake disc 76, spline 71 and roller 74 are all selected bearing steel GCr15 for use; Coefficient of friction ξ=0.012 between spline 71 and the roller 74, the external diameter value Φ 50h7 of spline 71 are being arranged under the situation of oil lubrication; Brake disc 76 internal diameter value Φ 50H7, the diameter value Φ 8h7 of roller 74.Set roller 74 and act on the power F=1000N on the brake disc 76, can know that by above principle and formula the adequate condition of natural locking state is:
f≥F2
＝＞ξ?*?F?*?cos?x°≥F?*?sin?x°
＝＞ξ≥tg?x°
When getting ξ=0.012, can calculate x °≤0.6875 °
As shown in Figure 7, the stressed angle (power F and the vertical angle that is connected roller center line and disc centres line) of getting spline 71 during design can reach instantaneous locking state during for x °≤0.6875 °.
Actual design adds gets x °=0.67 ° man-hour, can calculate:
0.67 °=11.999N of frictional force f=ξ * F * cos x °=0.012 * 1000 * cos
0.67 °=11.693N of tangential component F2=F * sin x °=1000 * sin
This moment, f-F2=0.306N satisfied the locking state condition.
Because it is very little through the power that thimble 73 is applied on the roller 74 to drive locking device spring 72, have only about 10N, act on power F3 on the roller 74 greater than 10.306N as long as therefore drive pawl 75, can remove locking state by transient solution.
Do not having external force to interfere under the situation of removing roller 74 locked angles, as can beappreciated from fig. 9, spline 71 can only rotate by clockwise direction all the time, can't counterclockwise rotate.After so just having guaranteed to press down openhanded the opening of handle 8, the clamping force between pressing plate 1 and the working panel 2 can keep instantaneous locking state.
The instantaneous principle of unclamping of clamping force:
As shown in Figure 8; On the raise one's hand manual end handlebar head 86 of handle 8; Through handle head 84 and drive the engaging tooth between the pawl 75 that drives of locking device 7, with driving moment pass to drive locking device 7 drive pawl 75, drive pawl 75 and overcome the elastic force of spring 72 and thimble 73 and the frictional force between roller 74 and spline 71 and the brake disc 76; Promote the stop that roller 74 breaks away between spline 71 and the brake disc 76, locking mechanism is disengaged.Raise one's hand in the continuation manual end handlebar head 86 of handle 8 drives pawl 75 and promotes rollers 74 and splines 71, through transmission system, will lead ratch 2 and lift with pressing plate 1, realizes being unclamped by instantaneous by the workpiece of clamping.
Realize the freely regulated structural principle of lever operated angle:
After confirming clamping thickness, turning handle 8 is raised to suitable height with pressing plate 1, presses down handlebar 85 then, and pressing plate 1 is depressed into by the air valve of clamping, and at this moment the not necessarily suitable operating personnel in handlebar 85 residing positions carry out reinforcing locking.If handlebar 85 residing angle positions are not easy to the locking of operating personnel's application of force; Can extract handle head 84 this moment from the pawl 75 that drives that drives locking device 7; Handle 8 is rotated to the position of suitable operation; Unclamp then, handle head 84 will automatically revert to and drive on the pawl 75 under the effect of spring 81 and shoulder screw 82.
Shown in figure 11, handle 8 is fixed on driving on the pawl 75 of locking drive unit through spring 81 and shoulder screw 82, and it is loosening for preventing shoulder screw 82 that a hole back-up ring 83 has been installed on the handle 8.Under the free state, spring 81 is pressed to handle head 84 and is driven pawl 75, makes handle head 84 and drive pawl 75 to be meshing with each other.Like the angle position of need adjustment handle 8, only need handle head 84 is extracted, intermeshing tooth is broken away from, and the design of the drift of shoulder screw 82 need not be become flexible shoulder screw 82, just in time meet engaging tooth and break away from required displacement.Any then rotary handle head 84 gets final product until the operating habit position that arrives the match operation personnel.
Realize the clamping structural principle that the air bleeding valve assembling settles at one go:
Because air bleeding valve in assembling process, must be flat on the exhaust valve lift limiter on the work top earlier, and then the spring of packing into successively, buffer substrate tablet, valve block, lift guide ring and valve seat; This moment since valve seat on centre bolt towards following, so common way is on work top, the exhaust valve lift limiter to be padded up, wait install each parts of air bleeding valve after; Again with hand with the air bleeding valve fastening; Turn, use clamp at last, tighten locking nut.
Shown in figure 12, the utility model can directly assemble on workbench, and need not air bleeding valve to be turned again when the assembly platoon air valve through U-lag 47 on U-lag on the work top 32 and the housing seat.
Through the installation way of the utility model, can avoid the dislocation of air bleeding valve inner body in assembling locking process, both improved operating efficiency, also improved assembly precision.
1, shown in figure 12, on the handle 8 of raising one's hand, pressing plate 1 is raised to about 1.5 times height of air bleeding valve 9 thickness;
2, shown in figure 13; Installation step and requirement by air bleeding valve 9; Earlier exhaust valve lift limiter 96 is lain on the work top 3 the exhaust valve closure spring 95 of packing into one by one then, exhaust valve lift guide ring 94, air bleeding valve buffer substrate tablet 93, air bleeding valve valve block 92 and air bleeding valve valve seat 91;
3, shown in figure 14, rotary handle 8 is pushed down air bleeding valve 9 with pressing plate 1; Draw-out handle 8 then, and rotary handle 8 once more, rotate to the angle position of handle 8 the most suitable operating personnel's application of forces after; Unclamp hand, handle 8 is self-return under the elastic force effect of spring 81, is engaged to and drives on the pawl 75.
Earlier slow rotary handle 8 lightly guarantees that pressing plate 1 overcomes exhaust valve closure spring 95 elastic force, air bleeding valve 9 each parts can steadily be seated and not misplace, and then firmly press down handle 8, make air bleeding valve 9 by firm clamping between pressing plate 1 and work top 3.Drive locking device 7 this moment can be instantaneous locked with chucking power automatically, prevents to relax.
4, shown in figure 15, through U-lag 47 on U-lag on the work top 32 and the housing seat, tighten air bleeding valve locking nut 97 to required moment from the below with spanner 98, accomplish the assembling of air bleeding valve 9.
