Abstract
The utility model relates to an inflatable detector for an oil seal type shock absorber. The detector adopts the technology of hydraulic and pneumatic drive. A left gas chamber clamping shock absorber and a right gas chamber clamping shock absorber are driven by hydraulic cylinders, so that the gas inflating parts of the shock absorbers form a closed gas chamber space; the on/off of inflatable gas paths are controlled by gas charging valves in two gas chambers; and the gas (special gas) required in the process are inflated to gas storage chambers of the shock absorbers by gas needles. A pneumatic detection device is arranged above the inflatable detector; a pressure head of the pneumatic detection device is lower than the highest position where connection rods of the shock absorbers are ejected out and is higher than the lowest position where the connection rods of the shock absorbers are contracted, so that when needing to be ejected out, the connection rods can be completely ejected out due to the blockage caused by the pressure head, thereby the refute force values of the connection rods of the shock absorbers are reversely measured. The whole action process can utilize can be automatically controlled by the utilization of the programming of a PLC (Programmable Logic Controller); and the pre-pressing distance of the pressure head can be determined. The detector is designed and produced according to the production field conditions of the current shock absorbers, can meet the assembly demands of the main shock absorber in the domestic market and is essential special equipment for the specialized production of the inflatable shock absorbers.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1, the utility model adopts hydraulic pressure, pneumatic actuation technology, clamps vibration damper, makes vibration damper aerating position form a sealed gas chamber, by air tube gas is filled into vibration damper air storage chamber, and this moment, damper linking member was compressive state.Loosen vibration damper then, connecting rod is ejected, under the reverse resistance of the strength pick-up unit of She Zhiing, the ejection of connecting rod is hindered, and can not eject fully up, thereby records the power of the refuting value after the inflation.
Be in particular, it comprises a mainframe 1, and reeling thick stick 2 on the other hand is set in the bottom of mainframe, and hand leading screw 1 upper end has mold seat 3, and mold seat 3 is used for seat and establishes vibration damper 4, and hand leading screw 2 can be adjusted the height of mold seat 3 to adapt to the vibration damper of different length.Intermediate altitude position at mainframe 1 is provided with anchor clamps, is used for the urceolus part of clamping vibration damper.Above anchor clamps, be symmetrically arranged with left and right two clamping cylinders 5,5 ' and left and right 2 air chambers 6,6 '.Left and right air chamber 6,6 ' is to be driven by left and right clamping cylinder 5,5 ' piston rod respectively, and piston rod is can level flexible, drives 2 air chambers deciliter.Left and right air chamber 6,6 ' height are consistent with the urceolus upper end of vibration damper, otherwise say, the purpose of adjusting the mold seat is just adjusted the height of vibration damper, make the urceolus upper end suitable with the air chamber height, when 2 air chambers is closed, the urceolus of vibration damper and the oil sealing between the connecting rod are in the airtight air chamber space.Left and right two clamping cylinders 5,5 ' are generally oil cylinder or cylinder.
One strength pick-up unit is set above mainframe 1, and strength pick-up unit main body is a hold-down cylinder 7, the piston rod of hold-down cylinder vertically down, the lower end of its bar connects pressure transducer 8, a pressure head is established in the lower end of sensor.Also be included in the device on the flexible stroke (also being the flexible stroke of piston rod) of pressure head a upper limit 9 and a lower limit 10 are set, they are meant two noncontacting switch sensors, control by induced signal.Its setting principle is: the height that the upper limit of ram travel can not be higher than damper linking member when stretching out fully, otherwise the power of the refuting value that can't test vibration damper; Height when the lower limit of pressure head can not be lower than damper linking member and compresses fully, otherwise damper linking member can't eject at all, also can damage vibration damper, and this situation should not occur.Therefore, upper limit and lower limit should be set rationally, make pressure head be in the stroke meta of damper linking member inflation At time of eject, rather than on the limit position, so just can detect the power of the refuting value of damper linking member.
Left and right air chamber 6 in the foregoing description, 6 ' as shown in Figure 2, each air chamber all is by overlapping 62 injection molded semicircular in shape in steel casing 61 and the polyurethane material, the internal diameter of cover all is less than the internal diameter of shell in the mouth place, wherein upper and lower limit, the internal diameter of interior cover is suitable with the physical dimension of vibration damper to be detected, is purpose can pass vibration damper and don't to cause the gas leakage of vibration damper air chamber space.When the closed clamping of 2 air chambers vibration damper, the oil sealing of vibration damper is in the airtight space M.On the air chamber therein, open an injecting hole 63, be connected with feeder.Feeder is provided with switch valve and tensimeter, the control air feed.The utility model uses the nitrogen inflation usually.
Clamping cylinder in the foregoing description and hold-down cylinder are hydraulic jack all generally, and conventional control such as various solenoid valves and pump, tensimeter is arranged.
The utility model also is provided with an air tube 11 in addition, and is independent with inflator, shown in Fig. 3,4, has faller gill 12 and the air slot on faller gill 13.Faller gill is inserted into the oil seal place when inflation, by the elasticity of oil sealing, dehisces to inflate in vibration damper; Finish in inflation, when air chamber separates, extract air tube at once, oil sealing is restored to the original state.
During detection, earlier vibration damper band air tube is gone into station, the strength pick-up unit falls, and pressure head is in preset height, such as, the strength value during pre-detection damper linking member compression 10mm amount, pressure head just drops to compression 10mm position.Clamping cylinder clamps then, and the air chamber closure starts the source of the gas inflation; After inflation finished, air chamber was opened, and pulls up air tube, allows damper linking member eject under the strength effect; When connecting rod pushes up mutually with pressure head, because connecting rod is under the thrust of gas in the jar, the trend that protrudes upward in addition, sensor on will demonstrate this and refute power value having pressed this moment.Compare with the theoretical value of vibration damper by this power value, just can judge whether it is qualified.
Whole course of action utilizes the programming of PLC programmable controller to realize control automatically.The precompressed distance of pressure head can be made by oneself.This inflator according to the production of current vibration damper industry on the spot situation design, produce, can satisfy the assembling needs of main vibration damper on the home market, be the requisite specialized equipment of inflatable vibration damper professional production.
The various embodiments described above only are used to illustrate the utility model; wherein the structure of each parts, connected mode etc. all can change to some extent; every equivalents of carrying out on the basis of technical solutions of the utility model and improvement all should not got rid of outside protection domain of the present utility model.
