Description
Technical field
The invention belongs to mechanical field, relate to the utensil that in the links such as processing, production and maintenance workpiece is carried out clamping, be particularly useful for solving the location and the fixing instrument of reciprocating compressor air valve each parts of air valve in assembling, dismounting and maintenance process.
Background technology
Compressor valve is the core component of reciprocating compressor, and usage quantity is big, belongs to consumable accessory.Work such as the assembling of air valve, dismounting, maintenance, cleaning occupy more than 30% of compressor checking maintenance workload.About assembling, dismounting and the maintenance of reciprocating compressor air valve, also do not have the clamping platform of specialty at present, solve the location of each parts of air valve, fixing and locking.Present stage, settling mode mainly contained following three kinds:
1, hammering method
This method is the most frequently used method of compressor user, and as shown in Figure 1, the employing spanner entangles the locking nut on the air valve, embraces air valve and spanner with hand then, the other end of spanner is knocked toward the ground, to reach the purpose that the air valve locking nut is locked or unclamped.
The shortcoming of this method is: when air valve assembles, can't locate each each parts of air valve, and the location of each parts of air valve,
Can only on workbench, manually finish in advance by operating personnel, convenient inadequately in the operation; In addition, in the process of knocking, also may cause the inner body dislocation, the damage inner body.
2, the bench vice clamping is fixed
The air valve profile is a cylinder, and this method is blocked two planes up and down of air valve and clamped air valve with the jaw of bench vice, screws up with a wrench then or unclamps the locking nut of air valve, sees also Fig. 2.
The shortcoming of this method is: when air valve assembles, can't locate each each parts of air valve, the location of each parts of air valve can only manually be finished on workbench in advance by operating personnel, and clamping makes things convenient in the operation on bench vice inadequately then; In addition, before bench vice clamps air valve, cause the spring and the valve block dislocation of air valve inside easily.
3, alignment pin and threaded rod briquetting clamping are fixed
This method is a compressor valve manufacturer method commonly used, by two pins are installed on workbench, be used for circumferentially fixedly air valve, then with two briquettings, by being fixed on two threaded screw rods on the workbench, down twist with the nut on each screw mandrel respectively, thereby, see also Fig. 3 until briquetting being pushed down fixedly air valve of air valve.
This method efficient is lower, and on the one hand, the clamping air valve is more time-consuming, and in addition, threaded screw rod damages easily in clamping process and lost efficacy.
More than three kinds of methods, assembling for air bleeding valve, all must with cushion block the air bleeding valve valve gap be maked somebody a mere figurehead pad on workbench earlier, pack into successively then spring, buffer substrate tablet, lift guide ring, the valve seat of air bleeding valve, grasp whole valve body again, air bleeding valve is overturn left-hand thread on work top, tighten the locking nut of air valve at last in order to last method.Whole process, not only operation easier is big, waste time and energy, and air bleeding valve is overturn left-hand thread on work top in, the inner body of air valve misplaces easily, causes finally can't correctly assembling.
Summary of the invention
The object of the present invention is to provide a kind of clamping platform that can clamp compressor valve fast, make air valve in clamping and unloading process, the parts of each air valve can not misplace, and can not be damaged yet, and improve the assembling of air valve and the accuracy and the operating efficiency of dismounting.
For achieving the above object, solution of the present invention is:
A kind of compressor valve quick-clamping platform comprises: mounting and clamping system, transmission system, drive system, this transmission adopted gear ﹠ rack structure.
Further, the computing formula of the clamping force that is obtained on the clamping platform is: F2=F1* (L/R)
Wherein: F2 is the clamping force that is obtained on the clamping platform; F1 is tangential driving pressure;
L is the driving force arm lengths; R is the reference radius of driven axle.
The computing formula of the clamping speed v that is obtained on the clamping platform is: v=h/t=(∫ (R*sin θ))/t
Wherein: v is the clamping speed that is obtained on the clamping platform, and h is a lifting value of leading ratch; R is the reference radius of gear shaft; θ is the angle of handle rotation, and t is the handle rotation θ required time of angle.

F1＝F*cos?x°
F2＝F*sin?x°
X ° of frictional force f=ξ * F1=ξ * F*cos between roller and the brake disc
When f 〉=F2, promptly x ° 〉=F*sin of ξ * F*cos is x °, x ° of x ° 〉=sin of ξ * cos, and simplifying the back is ξ 〉=tgx °; Roller promptly is in the nature locking state, and under the situation that does not have other external force effects, roller can't prolong counterclockwise mobile, and spline also just can't counterclockwise turn round because of roller is in locking state.
This moment is as long as counterclockwise rotate and drive pawl, and driving the power that pawl acts on the roller is F3, and when F3+F2＞f, roller just can leave the wedge shape dead-centre position, removes this locking state rapidly.Therefore the adequate condition of removing locking state is:
F3＞f-F2, i.e. F3＞F (x ° of x °-sin of ξ * cos)
When manufacturing and designing, select suitable coefficient of friction ξ and loading angle x °, can make the driving locking device instantaneous locked, simultaneously can be by on handle, applying external force F3, transient solution removes the locking state that drives locking device.
By selecting the material and the machining accuracy of brake disc and roller, determine corresponding brake disc and roller coefficient of friction ξ, by top computing formula as can be known, can just make that by design the power F3 that removes locking state is enough little so that f-F2 is enough little.

This handle can any application of force angle of free adjustment, when the workpiece of clamping different-thickness, is convenient to the thickness of operating personnel according to clamping workpiece, and handle is adjusted to the position of suitable operation.
The clamping process of air valve quick-clamping platform:
At the manual end handle head 84 of handle 8 F1 that exerts pressure, press down handle 8, by handle 8 and drive engaging tooth between the locking device 7, driving moment is passed to drive locking device 7;
Drive locking device 7 by first axle key 62, driving moment is passed to elastic shaft 6; Elastic shaft 6 passes to gear shaft 5 by second axle key 61 with driving moment;

The computing formula of clamping force is:
F2＝F1*(L/R)
The clamping force that is obtained on the F2---clamping platform
F1---manually is applied to the tangential pressure on the handlebar head 86
L---decreased food (air line distance between the axis of handlebar head 86 centers and gear shaft 5)
The reference radius of R---gear shaft 5
In embodiments of the present invention, if the value of setting L/R greater than 25, so clamping force F2 is more than 25 times of downforce F1 that manually apply.When F1=50Kgf, clamping force F2 of the present invention is greater than 1250Kgf, and the clamping air valve, the general clamping force that only needs 10～100Kgf in this embodiment of the present invention, only needs operating personnel to apply the power of 0.4～4Kgf on handle, can clamp air valve fast.
The quick-clamping Principles of Regulation of lift (clamping thickness):
As shown in Figure 6, the critical piece of transmission system comprises pressing plate 1, leads ratch 2, gear shaft 5, elastic shaft 6, drive locking device 7, handle 8 etc.,
V＝h/t＝〔∫(R*sinθ)〕/t

H-leads the lifting value of ratch 2
The reference radius of R-gear shaft 5
The angle of θ-handle 8 rotations
The 8 rotation θ required times of angle of t-handle
Contrast existing " bench vice clamping method " and reach " alignment pin and screw thread briquetting clamping fixing means ", promptly equally in the unit interval bench vice handle rotate a circle, the distance that jaw advances is a pitch value of screw mandrel; The screw thread briquetting rotates a circle, and the distance that briquetting advances also is a pitch value of briquetting screw thread.Usually the pitch of bench vice screw mandrel and briquetting screw thread is 2.5～5mm.Can calculate thus: 81.64/2.5=32.656
81.64/5＝16.328
Therefore can reach a conclusion: clamping speed of the present invention 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 by 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 by first axle key 61, and as shown in Figure 8, bigger diameter end is fixed on the spline 71 that drives locking device inside by second axle key 62.
As shown in Figure 9, circumferentially three uniform rollers 74 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 this moment release handle, three the circumferential uniform rollers 74 on the spline are respectively by the elastic thrust effect of the circumferential uniform thimble 73 of three circumferential uniform springs 72 and three, 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 by spline 71 because of elastic shaft 6 distortion is F,
Power F acts on the stress point of brake disc 76 by 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 power F=1000N on the brake disc 76, by above principle and formula as can be known, 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 x °=0.012*1000*cos of frictional force f=ξ * F*cos
0.67 °=11.693N of x °=1000*sin of tangential component F2=F*sin
This moment, f-F2=0.306N satisfied the locking state condition.
Because it is very little by 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 be seen from Figure 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, by handle head 84 and drive the engaging tooth between the pawl 75 of driving 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 roller 74 and splines 71, by transmission system, will lead ratch 2 and pressing plate 1 lifts, and realizes being unclamped by instantaneous by the workpiece of clamping.
Realize the freely regulated structural principle of lever operated angle:
After determining 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.
As shown in figure 11, handle 8 is fixed on driving on the pawl 75 of locking drive unit by 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.As 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 the required displacement of engaging tooth disengaging.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 is in assembling process, must earlier the exhaust valve lift limiter be flat on the work top, 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.
As shown in figure 12, the present invention can directly assemble on workbench, and need not air bleeding valve to be turned again when the assembly platoon air valve by U type groove 47 on U type groove 32 and the housing seat on the work top.
By installation way of the present invention, can avoid the dislocation of air bleeding valve inner body in assembling locking process, both improved operating efficiency, also improved assembly precision.
1, as 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, as 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, as 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, as shown in figure 15,, tighten air bleeding valve locking nut 97 to required moment, finish the assembling of air bleeding valve 9 from the below with spanner 98 by U type groove 47 on U type groove 32 and the housing seat on the work top.
The above-mentioned description to embodiment is can understand and apply the invention for ease of those skilled in the art.The person skilled in the art obviously can easily make various modifications to these embodiment, and needn't pass through performing creative labour being applied in the General Principle of this explanation among other embodiment.Therefore, the invention is not restricted to the embodiment here, those skilled in the art are according to announcement of the present invention, and not breaking away from the improvement that category of the present invention makes and revise all should be within protection scope of the present invention.
