Fitting.
The work process of the present embodiment is:
Step one, pretreatment.Manually oil pump carrier is put in the base of pressure regulator valve ramming system, according to the first conduction band
13 determine and put into position, adjust the first holding screw 21 on the first support plate 20 so that after oil pump carrier accurate positioning,
Rotating depression bar 17 makes briquetting 18 compress oil pump carrier, is jointly compressed by oil pump carrier with rand pressing bar axle 16.
Step 2, automatically it is pressed into pressure regulator valve.Manually take gas-liquid solenoid valve and O from feeding system, on O
Painting oils, and defensive position is dynamic to be contained in O on gas-liquid solenoid valve, and the gas-liquid solenoid valve that then will be equipped with O loads oil pump
Corresponding pressure head on bracket tool, whether sensor detection gas-liquid solenoid valve is entirely enclosed in pressure head.From pressure regulator valve magazine
Taking out choke valve in 10, choke valve manually loads its pressure head, pressure head uses negative-pressure adsorption choke valve.Press the button,
First equipment detect O whether on gas-liquid solenoid valve, if detecting, O exists, then forcing press 14 drives card
Clamp 19 decline, gas-liquid solenoid valve and choke valve are pressed into oil pump carrier simultaneously, have final position sensor and final position backstop
Guarantee that part is installed to put in place, but not injuring part, there is sensor to detect whether to put in place in bottom, otherwise equipment alarm.
Step 4, automatically it is pressed into catch.In pressure regulating valve hole, it is sequentially loaded into steel ball and spring, exists manual catch is adsorbed
On pressure head corresponding in oil pump carrier frock, there is negative pressure generator inside pressure head, negative pressure catch is held.Press by
Button, protective door falls, and cylinder 28 band dynamic head 25 declines, and catch is pressed into pressure regulator valve hot-pressing plastic.Pressure head 25 is
With temperature controlled hot pressing pressure head, it is ensured that catch will cause damage, thermal head have specific coatings, will not wire drawing.
The displacement transducer 33 being arranged on sensor stand 35 detects whether catch puts in place automatically, it is ensured that catch is pressed onto position not
Catch and oil pump carrier must be damaged.
Step 5, taking-up part are also checked.It is fully completed if all of technical process and meets technological requirement, then setting
Standby green display lamp is bright, and protective door automatically opens up, and part is taken out by workman, puts into subsequent processing after doing overall visual inspection
Oil pump carrier base in.If technical process is not fully completed or technological requirement not met, equipment then hard stop,
Red light lights, and display defect content on information board 3 immediately, and workman presses device reset button, takes out faulty part
Put it into collecting receptacle.
Step 5, return step one continue.
