Pressure regulator valve catch ramming system comprises column 24, steel ball pressure head 25, connector 26, contact 27, cylinder 28, rebound 29, conduction band 30, support plate 31, second holding screw 32, displacement transducer 33, press base 34, sensor stand 35 and cylinder fixed mount 36.Rebound 29, conduction band 30, support plate 31 and the second holding screw 32 form oil pump carrier positioner, guaranteeing that oil pump carrier is put into and taken out all can not injuring part, simultaneously in the process of press-in catch, this device is used for ensureing the registration of oil pump carrier, bearing-surface when rebound 29 is for press-fiting, this device is ensure that the speed changing frock takes quick change patten's design.Column 24 and press base 34 form the support of this system, and other parts are installed on this support.Cylinder fixed mount 36 is fixed by screws on column 24, is cylinder 28 provide the structural support.Cylinder 28 is connected with steel ball pressure head 25 by connector 26, and under the drive of cylinder 28, catch is pressed into pressure regulator valve by steel ball pressure head 25.Sensor stand 35 is arranged on column 24, and displacement transducer inserts sensor stand 35.When cylinder moves downward, contact 27 encounters displacement transducer 35, guarantees that catch is pressed onto position and can not damages catch and oil pump carrier.The frock of oil pump carrier there are negative pressure device and hot pressing pressure head.By hand catch is put into, utilize negative pressure device to be held by catch fixing.Hot pressing pressure head is with temp. control function, and temperature controlling range is 150 ~ 400 DEG C, and temperature controlled precision is ± 1 DEG C, and thermal head has specific coatings, and wire drawing phenomenon can not occur.
Accessory system comprises illuminating lamp 1, Working gantry 2, information board 3, electrical control cubicles 9, display board 11, elesocket 12, protection grating and collecting receptacle.Illuminating lamp 1 provides light source for whole operating process, ensures that operating environment can be carried out.Working gantry 2 uses the prefabricated components such as aluminium section bar, connector, roller to be formed by connecting, and is connected, ensures that workbench is stablized, the worktable panel made with steel plate is housed above by foundation bolt 8 with ground.Protection grating, adopts secondary light coral safeguard.If all technical process all complete and meet technological requirement, then the green display lamp of equipment is bright, and protective door is opened automatically, and part takes out by workman.The indication sensor having workpiece to enter in collecting receptacle and can only put the mechanism that can not take out into, when ensureing to occur assembling substandard product, there will not be maloperation.Driver, sensor, PLC, failure warning system is comprised in electrical control cubicles 9.Driver is for driving cylinder, and make cylinder export required pressure, sensor is connected with PLC by data wire, the data collected is passed in PLC by data wire.Failure warning system is connected with PLC by data wire with button, indicator lamp etc., wherein failure warning system and indicator lamp are output devices, button is entering apparatus, also the abnormal conditions in equipment running process are differentiated while the omnidistance action of control, and make the respective handling such as failure identification, parking warning, failure logging.Display board 11 can the current duty of display be normal or fault in real time.Elesocket 12 is the connector installing protective cover.
The course of work of the present embodiment is:
Step one, pretreatment.Manually oil pump carrier is put into the base of pressure regulator valve ramming system, determine to put into position according to conduction band 13, the first holding screw 21 on adjustment support plate 20, after making 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, be automatically pressed into pressure regulator valve.Manually get gas-liquid solenoid valve and O type circle from feeding system, on O type circle, painting oils, and defensive position is dynamic to be contained on gas-liquid solenoid valve by O type circle, then the gas-liquid solenoid valve that O type circle is housed is loaded the pressure head of the correspondence in oil pump carrier frock, sensor detects gas-liquid solenoid valve and whether loads pressure head completely.From pressure regulator valve magazine 10, take out choke valve, manually choke valve is loaded its pressure head, pressure head uses negative-pressure adsorption choke valve.Press the button, first equipment detect O type circle whether on gas-liquid solenoid valve, if detect, O type circle exists, then forcing press 14 drives clip pressure head 19 to decline, simultaneously by gas-liquid solenoid valve and choke valve press-in oil pump carrier, there are final position sensor and final position backstop to guarantee that part is in place, but not injuring part, have sensor to detect whether to put in place in bottom, otherwise equipment alarm.
Step 4, be automatically pressed into catch.In pressure regulating valve hole, load steel ball and spring successively, on manual pressure head catch being adsorbed on correspondence in oil pump carrier frock, there is negative pressure generator pressure head inside, is held by catch by negative pressure.Press the button, protective door falls, and cylinder 28 is with dynamic head 25 to decline, and catch is pressed into pressure regulator valve and hot-pressing plastic.Pressure head 25 is with temperature controlled hot pressing pressure head, and guarantee to cause damage to catch, thermal head has specific coatings, can not wire drawing.Whether the displacement transducer 33 be arranged on sensor stand 35 automatically detects catch and puts in place, guarantees that catch is pressed onto position and must not damages catch and oil pump carrier.
Step 5, take out part checking.If all technical process all complete and meet technological requirement, then the green display lamp of equipment is bright, and protective door is opened automatically, and part takes out by workman, puts into the oil pump carrier base of subsequent processing after doing overall visual inspection.If technical process does not all complete or technological requirement does not meet, equipment is hard stop then, and red light lights, and display defect content on information board 3 immediately, workman presses device reset button, takes out faulty part and puts it into collecting receptacle.
Step 5, return step one continuation.
