Below will combine accompanying drawing, the workflow of plug screw sealing ring assembling of the present invention and each device thereof will be done further detailed explanation.
The sealing ring material loading action of plug screw sealing ring assembling of the present invention, support ring action, barring-on move, the plug screw material loading moves and the lasso action is all carried out synchronously, and the interoperation between each device will be explained when introduction is respectively installed workflow in detail.Below mainly combine accompanying drawing and the workflow of each device is elaborated.
One, the detailed description of the workflow of sealing ring feeding device:
The first step: as shown in Figure 8; Material loading cylinder 2-4 is in the state that stretches out fully; Under the effect of compression spring 2-8, make the through hole on flitch 2-6 and the last flitch sole piece 2-11 be in the dislocation state simultaneously; In the stock chest of storing piece 2-1, arrange a certain amount of O RunddichtringO of heap, and guarantee to have only an O RunddichtringO to be in the through hole of flitch 2-6.
Second step: as shown in Figure 9, the withdrawal of material loading cylinder 2-4 piston rod, last flitch 2-6 and last flitch sole piece 2-11 move together; When last flitch pushing block 2-7 pushes up storing piece 2-1, last flitch 2-6 will no longer move, and going up flitch sole piece 2-11 afterwards will the motion that offset take place with last flitch 2-6.
The 3rd step: shown in figure 10; When material loading cylinder 2-4 piston rod is withdrawn fully; Compression spring 2-8 is compressed; The through hole that last flitch 2-6 and last flitch sole piece 2-11 are offsetted on it is just overlapping, the O RunddichtringO 2-3 in last flitch 2-6 through hole then can just from fall down the through hole on flitch 2-6 and the last flitch sole piece 2-11.
The 4th step: shown in figure 11, the O RunddichtringO 2-3 that from the last flitch 2-6 of sealing ring feeding device 2 and the through hole between the last flitch sole piece 2-11, falls down then just falls the otch place at the rocking bar 1-10 of ring-supporting device 1 (state shown in Figure 11).
Only then material loading cylinder 2-4 piston rod stretches out fully again, and gets back to state as shown in Figure 8, is an operation cycle at this point, has just accomplished the automatic charging flow process of an O RunddichtringO.
Two, the detailed description of the workflow of ring-supporting device:
Shown in figure 11; The withdrawn distance of second stroke of the piston rod of the support ring cylinder 1-3 of ring-supporting device 1; Just whole motivation frame base plate 1-6 and the part that links together with it have been moved down the distance of second stroke along axis of guide 1-4, thus the state when making ring-supporting device 1 be in completion O RunddichtringO automatic charging shown in Figure 11 to move.And then be the follow-up workflow explanation in a cycle period of ring-supporting device 1.
The first step: shown in figure 12, the piston rod of support ring cylinder 1-3 continues withdrawal, and the distance of first stroke of withdrawal.Because whole motivation frame base plate 1-6 and on linear bearing 1-7 be fixed on retainer ring 1-5 on the axis of guide 1-4 and limit and can not continue to move down, move down thereby the piston rod of support ring cylinder 1-3 just can drive slide block 1-13.The slide block endplay device that drives by same slide block of the quadruplet circumference uniform distribution formed such as rocking bar 1-10, connecting rod 1-12 and slide block 1-13 wherein; Because the moving downward of slide block 1-13 driven the swing of four rocking bar 1-10 around pin joint, and then realized the big function of O RunddichtringO support.
Second step: like Figure 13 and shown in Figure 14, accomplished the function that O RunddichtringO 2-3 support is big after, the piston rod of the support ring cylinder 1-3 of ring-supporting device 1 will be protruding fully, promptly stretch out the distance that first stroke adds second stroke.Shown in figure 13; The piston rod of support ring cylinder 1-3 extend out to motivation frame 1-6 and on linear bearing 1-7 push up till the retainer ring 1-5 that is positioned at axis of guide 1-4 upper end; Above-mentioned slide block endplay device will continue to keep with the big state of O RunddichtringO support, and then the O RunddichtringO 2-3 after making support big can intert the outside at barring-on guide pin bushing 4-4 shown in Figure 13.And then; Shown in figure 14; Because the restriction of retainer ring 1-5, the slide block 1-13 of above-mentioned slide block endplay device moves upward with piston rod, drives rocking bar 1-10 and back swings and removed the support ring effect to the O RunddichtringO; The rocking bar 1-10 just fluting from the barring-on guide pin bushing 4-4 interted, thereby made sealing ring 2-3 can resilience dwindle and be enclosed within on the barring-on guide pin bushing 4-4.
Then next step is the piston rod of the support ring cylinder 1-3 of ring-supporting device 1 distance of second stroke of withdrawing, and gets back to state shown in figure 11, and the above promptly is the workflow of 1 one cycle periods of ring-supporting device.
Three, the detailed description of the workflow of transfer device and topping stand:
The first step: accomplished the big back of O RunddichtringO support and be enclosed within on the barring-on guide pin bushing 4-4 by above-mentioned ring-supporting device 1,4 of the transfer devices of barring-on guide pin bushing 4-4 that promptly are with the O RunddichtringO this moment are shown in figure 15.To the rotary cylinder 4-1 among Figure 15 ventilation, drive the 4-3 that sets a table and counterclockwise turn round 180 °, with the barring-on guide pin bushing 4-4 that is with the O RunddichtringO return back to topping stand 5 directly over.And then, the lift cylinder 5-1 of topping stand 5 will drive clamping and the pneumatic-finger 5-4 of plug screw 3-9 and rise, and the hollow space of the barring-on guide pin bushing 4-4 that plug screw 3-9 is just injected be with the O RunddichtringO, and will be shown in figure 16 after accomplishing.
Second step: shown in figure 17; The knocking over cylinder 4-6 piston rod of transfer device 4 upper left sides stretches out fully; And drive the knocking-over bar 4-5 on it; Break away from and retraction falls the precalculated position to the plug screw 3-9 from barring-on guide pin bushing 4-4 being enclosed within the sealing ring that is stretched on the barring-on guide pin bushing 4-4, realized plug screw lasso function, the plug screw 3-9 that accomplishes behind the cover O RunddichtringO is shown in figure 18.
The 3rd step: the lift cylinder 5-1 of topping stand 5 descends, and pneumatic-finger 5-4 comes loose then, and the plug screw 3-9 that accomplishes lasso is come loose, and makes within its plug screw tapping channel 6-4 that vertically falls into frame 6, has accomplished accomplishing the discharging of lasso plug screw.When opening pneumatic-finger 5-4; Knocking over cylinder 4-6 piston rod is withdrawn fully; Rotary cylinder 4-1 oppositely ventilates; Drive 180 ° of the 4-3 clockwise direction revolutions of setting a table are accomplished opposite side to be with the barring-on guide pin bushing of O RunddichtringO and the barring-on guide pin bushing in left side shown in Figure 17 carries out the switching of position synchronously.
The above is the interior workflow of a cycle period of transfer device 4 and topping stand 5 interoperations.
Four, the detailed description of the workflow of plug screw feeding device:
The first step: shown in figure 19, the piston rod of material loading cylinder 3-3 stretches out fully, then in the stock chest of storing piece 3-1, vertically arranges and is storing several plug screws 3-9, and can make a lowermost plug screw 3-9 just be in the pusher notch place of flitch 3-6.
Second step: the piston rod of material loading cylinder 3-3 is withdrawn fully, and a lowermost plug screw 3-9 passes out to assigned address with last flitch 3-6 forward along the passage that two limiting plate 3-8 form, and is shown in figure 20 after accomplishing.
The 3rd step: shown in figure 21; After plug screw 3-9 was sent to assigned address, the topping stand 5 that pneumatic-finger 5-4 is in open configuration began the closure with pneumatic-finger 5-4, just plug screw 3-9 is grasped; Follow-up then is the lasso action, has accomplished the automatic charging function of plug screw at this point.After plug screw 3-9 was held, the piston rod of material loading cylinder 3-3 stretched out fully, gets back to state shown in Figure 19, accomplished a periodic duty cycle.
The above is the interior workflow of a cycle period of plug screw feeding device 3.
