As shown in Figure 1; The present invention includes a pressure gas tank 4; Pressure gas tank 4 connects sealing pneumatic head 14 through high-pressure aerated system; As shown in Figure 7, be provided with pressure gas knock out drum 11 in the said high-pressure aerated system, pressure gas tank 4 is through pipeline be linked in sequence reduction valve 32 (reduction valve is not shown among Fig. 7), first pneumatic triple piece 1, first solenoid valve 10, pressure gas knock out drum 11, pressure relay 18, second solenoid valve 13 and the 3rd solenoid valve 12.
As shown in Figure 1; Said sealing pneumatic head 14 is affixed with frame 31; Like Fig. 5, shown in Figure 6, the cross section of sealing pneumatic head 14 is " T " shape, has locating slot 14-3 on the sealing pneumatic head 14; Locating slot 14-3 is circular, the device first seal ring 14-1 and the second seal ring 14-2 in locating slot 14-3; Inside in sealing pneumatic head 14 has gas-entered passageway 14-5, filling channel 14-4 and exhaust passage 14-6; Gas-entered passageway 14-5 communicates with filling channel 14-4 and exhaust passage 14-6; Gas-entered passageway 14-5 is connected with the air outlet of above-mentioned second solenoid valve 13, and exhaust passage 14-6 is connected with the suction port of the 3rd solenoid valve 12.
As shown in Figure 1, connect a horizontal pressing plate 26 on the top of 8, two vertical connecting plates 8 of sealing two vertical connecting plates of pneumatic head 14 both sides returning apparatus through fastening piece; Laterally installing a fastening device on the pressing plate 26; As shown in Figure 4, said fastening device comprises the supporting plate 27 affixed with horizontal pressing plate 26, has the screw rod mounting hole on the supporting plate 27; The linear ball axle sleeve 30 of device in the screw rod mounting hole; One end of screw rod 22 runs through and is connected in supporting plate 27, and the other end of screw rod 22 passes horizontal pressing plate 26 and is connected with briquetting 15, the periphery connection gear 25 of screw rod 22; Side at said supporting plate 27 connects guiderail base 28, device guide rail 24 on the guiderail base 28, and guide rail 24 is slidingly connected with tooth bar 23, gear 25 and tooth bar 23 engagements.
Like Fig. 2, shown in Figure 3, an end of tooth bar 23 is threaded with the piston rod 29 of cylinder 2, and cylinder 2 is fixed on the positioning plate 32, and positioning plate 32 is installed on the frame 31.Cylinder 2 connects source of the gas through low voltage control system, and is as shown in Figure 8, comprises cylinder 2, and source of the gas 34 is through pipeline be linked in sequence second pneumatic triple piece 3, the 4th solenoid valve 5, one-way throttle valve 33 and cylinder 2.
Working procedure of the present invention is following:
Low voltage control system drives cylinder piston rod and stretches out:
As shown in Figure 1, nitrogen spring 9 is placed in the locating slot 14-3 of sealing pneumatic head 14, because locating slot 14-3 matches with the air spring periphery, guaranteed the accurate location of nitrogen spring 9; Low voltage control system work; As shown in Figure 8; Source of the gas 34 is connected, and airflow passes second pneumatic triple piece 3, the second pneumatic triple pieces 3 comprise air filter 3-1, reduction valve 3-2 and oil sprayer 3-3; Played the impurity in the filtering gas, steady flow is through gas pressure and to the lubricated effect of subsequent element; Gas gets into cylinder 2 in a point back through the 4th solenoid valve 5 and makes its work, and is constant for guaranteeing gas and atmospheric pressure in the cylinder 2, discharges from the b point of the 4th solenoid valve 5 behind the unnecessary gas process one-way valve 33-1; Above-mentioned source of the gas is through the compressor compresses air, then pressurized air stored in the compression gas tank, and through pipeline UNICOM second pneumatic triple piece 3 (compression gas tank, compressor are not shown, belong to prior art).
The work of air cylinder driven fastening device:
Extremely shown in Figure 4 like Fig. 1; Cylinder 2 work make piston rod 29 motions; Because piston rod 29 is threaded with tooth bar 23, and tooth bar 23 and gear 25 engagements, thereby the straight line motion of piston rod 29 is converted into rotatablely moving of gear 25; Gear 25 rotating drive screw rods 22 are moving linearly down, compresses the upper-end surface of air spring 9 until the briquetting 15 of screw rod 22 1 ends; Because screw rod 22 self-locking properties are better, guaranteed that nitrogen spring 9 is not loosening in gas replenishment process; Owing to install the first seal ring 14-1, the second seal ring 14-2 in the locating slot 14-3 of sealing pneumatic head 14, under the effect of clamping force, the bottom surface butt of the end face of each seal ring and nitrogen spring 9 seals reliably nitrogen spring 9 in high-pressure aerated process simultaneously.
High-pressure aerated system works:
As shown in Figure 7, gas flows out through behind the reduction valve 32 in pressure gas tank 4, gets into first pneumatic triple piece, 1, the first pneumatic triple piece 1 and comprises air filter 1-1, reduction valve 1-2 and oil sprayer 1-3, and its effect is identical with second pneumatic triple piece 3; Gas passes through first solenoid valve 10 through first pneumatic triple piece, 1 back; Get into press knock out drum 11 then; It is constant that press knock out drum 11 can be controlled the gas pressure that charges in the nitrogen spring 9, when the pressure of press knock out drum 11 internal gas descends, can open first solenoid valve 10 automatically and carry out tonifying Qi; Simultaneously second solenoid valve 13, the 3rd solenoid valve 12 can be in off-position, guarantee that gas can't get in the nitrogen spring 9.Constant and when being in the value that pressure relay 18 sets when gas pressure in the press knock out drum 11; Gas gets into second solenoid valve 13; Because inlet hole 14-5 and 13 of second solenoid valves in the above-mentioned sealing pneumatic head 14 link through pipeline, accomplish gas replenishment process thus, after the inflated; Because the exhaust port 14-6 in the sealing pneumatic head 14 is connected with the 3rd solenoid valve 12 through pipeline, so residual gas can be discharged through the 3rd solenoid valve 12; Pressure relay 18 carries out the pressure setting according to the pressure of air spring workpiece needs in 0 ~ 10MPA scope, according to its required precision, maximum pressure and minimum pressure value in the gas replenishment process can be set, and guarantees that inflation pressure fluctuates in a small range.
Low voltage control system drives the cylinder piston rod withdrawal:
As shown in Figure 8, after inflated, source of the gas 34 is connected; Flow through behind second pneumatic triple piece 3,, pass through then to get in the cylinder 2 behind the throttle valve 33-2 through the c point of the 4th solenoid valve 5; Make cylinder 2 work; The piston rod withdrawal, constant for guaranteeing gas and atmospheric pressure in the cylinder 2, unnecessary gas is discharged through the d point of the 4th solenoid valve 5.
As shown in Figure 1; First switch 7, second switch 16, green indicating lamp 19, red led 21, emergency stop button 20 and first optoelectronic switch 6, second optoelectronic switch 17 all belong to conventional design, and wherein whether first optoelectronic switch 6, second optoelectronic switch 17 place in the sealing pneumatic head 14 for detecting air spring 9; First switch 7, second switch 16 prevent to bump the situation that makes machine works because of operator's mistake, have only when pressing first switch 7, second switch 16 simultaneously, could realize the proper functioning of machine.Green indicating lamp 19 lights, expression machine proper functioning, and red led 21 lights, and there is fault in the expression machine, and emergency stop button 20 is that operator can reach the measure of protection through pressing this button fast in the time of the generation urgency.
The said pneumatic triple piece and first solenoid valve, second solenoid valve, the 3rd solenoid valve, the 4th solenoid valve valve and one-way throttle valve are the commercial goods, and the electric controller of said air-channel system adopts prior art.
More than describing is to explanation of the present invention, is not that institute of the present invention restricted portion is referring to claim to the qualification of invention, and under the situation of basic structure of the present invention, the present invention can do any type of modification.
