Abstract
The utility model as is an expansion type round hole sealability detection auxiliary device, which is composed of a cylinder, a piston, a piston rod, a sealant and a locking screw, an air inlet nozzle communicated with a cylinder inner cavity is provided above a column-shaped cylinder; a column-shaped piston is arranged in the cylinder, an annular seal ring tightly contacted with the cylinder inner wall is provided at the piston outer wall; one column-shaped piston rod is provided at the right side of the piston, an annular elastic seal glue is provided at the outer wall of the piston rod; and a locking screw nail enabling the sealant to be fixed on the piston rod is provided at the right side of the piston rod. The utility model has advantages of simple and reasonable, convenient and fast application, , simple sealant changing course, cost saving and strong universality, and is suitable for product detection in bulk production.
Description
Technical field:
The utility model relates to product sealing detection field, and especially a kind of expansion type circular hole sealing detects servicing unit.
Background technology:
When the die-cast product of production and processing aluminium alloy and other metal, in order to detect the influence of pore in the product, shrinkage cavity, die casting defective such as loose to product, some product need be done sealing property and detect, test process will seal, inflate then and detect the interior die cavity that product need detect, in the middle of to the product hermeticity actual detected, usually need to use the sealing detection servicing unit die cavity in the product is sealed, the sealing detection servicing unit plays an important role to the sealing detection result.Wherein the sealing of the aperture in the metal product inner round wall detects, singularity because of its position, so sealing is detected servicing unit very high requirement is arranged, be the sealing column of fixed in shape because of traditional circular hole sealing detects servicing unit again, and cause that traditional circular hole sealing detects that the servicing unit versatility is poor, seal process instability, cargo handling process be numerous and diverse, is that the product of enterprise detects and increased cost and inconvenience.
The utility model content:
The utility model detects the design of servicing unit by a kind of expansion type circular hole sealing, make the circular hole sealing detect that the servicing unit versatility is good, seal process stable, cargo handling process is simple, be applicable to the detection of in the batch process aperture in the inner round wall of product being carried out sealing property.
The utility model is made up of cylinder body, piston, piston rod, fluid sealant, lock-screw, and cylindricality cylinder body top is provided with the admission piece that is connected with inner chamber of cylinder block; Be provided with a cylinder-piston in the cylinder body, described piston outer wall is provided with a grommet type seals that closely contacts with inboard wall of cylinder block; The piston right side is provided with a cylinder-piston bar, and the piston rod outer wall is provided with the cyclic spring fluid sealant; The piston rod right side is provided with one can make fluid sealant be fixed on lock-screw on the piston rod.
When using the utility model, admission piece is linked to each other with a gas outlet of sealing detecting instrument, on piston rod, lock-screw taken off and be inserted in thickness suitable cyclic spring fluid sealant makes the fluid sealant external diameter be slightly less than Circularhole diameter, with piston rod together with in the whole circular hole that inserts required detection sealing of fluid sealant and make its left end expose circular hole, the lock-screw piston rod of packing into, promptly begin testing, the cylinder body inflation, piston drive piston rod and lock-screw are to left movement, lock-screw crush seal glue, fluid sealant is subjected to compression swelling and the aperture of required detection on the interior circular hole wall is sealed, the sealing property testing process begins, and after the product hermeticity detection was finished, cylinder air inlet disconnected, fluid sealant relies on self elastic reset, and cylinder body and fluid sealant integral body withdraw from product sealing position
The utility model is simple and reasonable for structure, and is convenient to use, and the replacing process of fluid sealant is simple, is applicable in the batch process the product testing, has the advantages that to save cost, highly versatile.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model, also is that specification digest is with scheming.Each label is respectively among the figure: (1) admission piece; (2) cylinder body; (3) O-ring seal; (4) piston; (5) piston rod; (6) lock-screw; (7) fluid sealant.
Embodiment:
Now give an example in conjunction with the accompanying drawings, the utility model be described further:
