SUMMERY OF THE UTILITY MODEL

In order to solve the above problems, the present invention provides an O-ring assembling apparatus for automatically mounting a seal ring to a coupling head.

In order to achieve the purpose, the O-shaped ring assembling device comprises a support, an air cylinder, a push rod, a loop bar, a fixing sleeve and a pressure spring, wherein the support comprises a support plate and two inserts which are perpendicular to the support plate and are fixedly connected with the support plate, the two inserts are respectively provided with the air cylinder and the fixing sleeve, the insert provided with the air cylinder is called an upper insert, the insert provided with the fixing sleeve is called a lower insert, the working end of the air cylinder faces the direction of the fixing sleeve, the push rod is arranged in the support, the lower part of the push rod is sleeved with the pressure spring, the tail end of the push rod is in an inverted cone shape, the middle part of the push rod is provided with a long strip-shaped limiting groove which penetrates through the diameter of the push rod, the extending direction of the limiting groove is consistent with the axial direction of the push rod, the middle part of the loop bar is provided with a through hole which is corresponding to the upper limiting groove of the push rod, the axial direction of the through hole is vertical to the loop bar axial direction, the limiting rod is arranged in the through hole, and one end of the loop bar, which is close to the cylinder, is provided with a shoulder, the upper end surface of the shoulder is contacted with the lower end of the pressure spring, the upper end surface of the lower insert is connected with a fixed sleeve, and the loop bar is arranged in the fixed sleeve. The structure design can realize mechanical automation, replaces manpower, and sleeves the O-shaped ring into the airtight connector, when the O-shaped ring is in a grabbing state, the cylinder ejects the ejector rod, the inverted cone part of the push rod is ejected out of the loop bar, the loop bar is pushed against the fixed sleeve because the limiting rod is driven by the limiting groove on the push rod, the lower end of the loop bar is exposed out of the lower end of the fixed sleeve, and the O-shaped ring is sleeved on the loop bar; when the O-shaped ring is in an installation state, the cylinder retracts, the push rod is pushed against the airtight connecting head due to downward movement of the support, the inverted cone end of the push rod is pushed into the loop bar by the airtight connecting head, the lower end of the loop bar is pulled back into the fixed sleeve due to the fact that the limiting rod is driven by the limiting groove in the push rod, the O-shaped ring on the loop bar is pushed out of the loop bar by the fixed sleeve due to relative movement between the fixed sleeve and the loop bar and is sleeved on the airtight connecting head. The function of the pressure spring is to ensure that the loop bar is in a good working position, meanwhile, the matching of the limiting rod and the limiting groove on the loop bar can further control the push rod to be in a good working position, and the shoulder is used for positioning the loop bar and the fixed sleeve and preventing the loop bar from sliding out of the lower part of the fixed sleeve.

In order to ensure that the length of the sleeve rod can work normally, when the shoulder of the sleeve rod is close to the upper end surface of the fixed sleeve, the lower end of the sleeve rod should exceed the lower end of the fixed sleeve; when the push rod retracts, the lower end of the sleeve rod can be completely pulled back to the position above the lower end of the fixed sleeve due to the arrangement of the limiting groove. The length of the sleeve rod is greater than that of the fixed sleeve, and the sleeve rod can be sleeved into the outer ring of the sleeve rod when the O-shaped ring is grabbed due to the structural design; the sleeve rod needs to retract into the fixed sleeve when the cylinder retracts, so that the O-shaped ring can be detached from the fixed sleeve.

In order to ensure the length of the push rod to work normally, when the push rod is ejected to the limit position, the inverted cone part of the push rod should be completely exposed out of the lower end of the loop bar. The design is that when the O-shaped ring is grabbed, the inverted cone part of the push rod can be used as a transition part, and the O-shaped ring is pushed into the sleeve rod part.

According to the O-shaped ring assembling device, the ejector rod is pushed through the air cylinder, so that the push rod is pushed, and the effects of grabbing and installing the O-shaped ring are achieved through the linkage of the limiting groove and the limiting rod between the push rod and the sleeve rod and the mutual moving fit between the sleeve rod and the fixing sleeve; and by adopting automatic design, the working process of sleeving the O-shaped ring into the airtight connector is simplified, the labor is replaced, and the labor cost is saved.
