Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
The motorcycle starting motor front end end cover air-tightness detection device of the utility model; Comprise the stand 2 that is provided with closed cavity 201, be arranged on pore 202, sealing pressure head 3, source of the gas, connection cavity 201 and source of the gas on the stand 2 gas piping 4, be arranged on the air valve 5 on the gas piping 4; Said sealing pressure head 3 cooperates with the sidewall hermetic seal in the oil sealing chamber 111 of the axis hole part 110 of front end end cover 1; Said cavity 201 is through the oil sealing chamber 111 of the axis hole part 110 of pore 202 connection front end end covers 1, and said cavity 201 is isolated from the outside through the hermetic seal cooperation of front end end cover 1 and stand 2.
During use, front end end cover 1 is placed on the stand 2, and covers the endoporus of 1 axis hole part 110 with the closed front that cooperates of oil sealing chamber 111 sidewalls, make stand 2 cavitys 201 be isolated from the outside through sealing pressure head 3; Opening air valve 5 then makes cavity 201 and source of the gas be communicated with through gas piping 4; And then the air pressure in the change cavity 201; Through cavity 201 and outside pressure reduction front end end cover 1 oil sealing 113 sealing properties are detected, therefore can before the actuating motor assembling, check oil sealing 113 sealing properties of front end end cover 1.
Further, like Fig. 1, Fig. 2, shown in Figure 3, said sealing pressure head 3 comprises the oil sealing sealing pressure head 302 that seals pressure head 301, cooperates with the 111 sidewall hermetic seals of oil sealing chamber through oil sealing 113 through the sidewall that cooperates with the 111 sidewall hermetic seals of oil sealing chamber of test O-ring seal 112.Through 301 pairs of sidewall sealing pressure heads front end end covers 1 before the oil sealing 113 are installed and are carried out impermeability and detect, thereby detect the sealing property in oil sealing chamber 111 self; Carry out impermeability through the front end end cover 1 behind 302 pairs of installations of oil sealing sealing pressure head oil sealing 113 and detect, thus the sealing property of detection front end end cover 1 user mode.
Operation for ease; In like Fig. 1, Fig. 2, instance shown in Figure 3; Concrete, said front end end cover 1 axis hole part 110 is inserted in the pore 202, and said front end end cover 1 cooperates with pore 202 sidewalls formation hermetic seal with the O-ring seal 114 of stand 2 through axis hole part 110 outer peripheral faces of front end end cover 1.
Detection to sealing property can realize through the detection to cavity 201 internal gas pressures.But detect for ease, said pore 202 axis vertically are provided with and are positioned at front end end cover 1 below, constitute liquid storage cylinder 203 by the axis hole part 110 of sealing pressure head 3 closed front lid 1 and by the end cap part 120 of front end end cover 1.During use, in liquid storage cylinder 203, charge into liquid, when above-mentioned source of the gas adopted the negative pressure source of the gas, if poor sealing, liquid can run off, and therefore can judge sealing property through the level change in the liquid storage cylinder 203; When above-mentioned source of the gas adopts high-pressure air source, if poor sealing then can bubbling, therefore can through whether having bubble that sealing property is judged.
Observation relative liquid surface to bubble changes more convenient; Simultaneously, adopt high-pressure air source, during with front end end cover 1 actual the use, seal request from outside to inside adapts.Therefore in instance as shown in the figure, said source of the gas is a high-pressure air source; Simultaneously, for fear of under the high pressure effect, front end end cover 1 displacement so influence front end end cover 1 and stand 2 between sealing effectiveness, be provided with the temporary fixed mechanism that is fixedly connected stand 2 and front end end cover 1.
Owing to adopt high-pressure air source, insert the liquid into liquid storage cylinder 203 for ease, and after accomplishing detection, avoid liquid to flow into cavity 201, be provided with the feed tube and the liquid suction pipe that are connected with liquid storage cylinder 203.In instance as shown in the figure, feed tube and liquid suction pipe all adopt valvular hand-held flexible pipe are set.
Above-mentioned sealing pressure head 3 can be installed through artificial, and temporary fixed mechanism can adopt mechanisms such as clip.Operation for ease; In instance as shown in the figure, be provided with base plate 601, be installed in the pillar 602 on the base plate 601, said stand 2 is installed on the base plate 601; Be provided with the straight line driving mechanism that drives sealing pressure head 3, said sealing pressure head 3 is installed on the pillar 602 through straight line driving mechanism; Said temporary fixed mechanism is made up of the sealing pressure head 3 that cooperates with front end end cover 1 upper limit, the stand 2 that cooperates with front end end cover 1 lower limit.Concrete, owing to adopt high-pressure air source, in order to simplify the internal structure of an organization, said straight line driving mechanism adopts cylinder.Sidewall sealing pressure head 301, oil sealing sealing pressure head 302 are installed through screw thread, and be during use, replaceable.
Because sealing pressure head 3 cooperates with front end end cover 1 upper limit; It is excessive to press partially or depress for fear of sealing pressure head 3; Thereby cause the infringement of sealing pressure head 3, front end end cover 1, said sealing pressure head 3 links to each other with straight line driving mechanism through connecting rod 604, is provided with the limiting plate 603 that is installed on the pillar 602; Said connecting rod 604 cooperates with limiting plate 603 slide-and-guides, and constitutes the smallest limit position limiting structure of connecting rod 604 by limiting plate 603.
