End, tail pipe pressing device are mounted on position adjacent with stern tube sealing in connect base；Flange positioning device, which is mounted on, to be connected
It connects on pedestal and close to flange sealer, the tail pipe pressing device uses cylinder-pressing, and flange sealer and tail pipe are close
Seal apparatus respectively includes bearing, cylinder and seal head, and cylinder is mounted on bearing, and seal head is mounted on the push rod of cylinder, institute
It states seal head and is equipped with the air admission hole and venthole communicated.
Further, the flange positioning device uses the bearing with rectangular notch.
Further, the tail pipe pressing device includes bearing and cylinder, and cylinder is mounted on the top of bearing, and cylinder
Push rod drives downwards, and bearing is equipped with the band arc-shaped slot riser for installing tail pipe.
Further, the cylinder installation of the stern tube sealing is angled, and angle is to ensure seal head and quilt
The tail pipe oral area for examining product is vertical.
Further, the seal head uses silica gel, venthole to be located at the center of seal head front end face, and air admission hole is located at
The side of seal head.
Further, the flange positioning device, the branch of flange sealer, stern tube sealing and tail pipe pressing device
Seat is bolted in connect base respectively.
The utility model has the advantages that：It is controlled using cylinder, it is convenient and efficient, for the chucking power of product to be checked
Stablize adjustable；Seal head uses silica gel, sealing effect good；The utility model also have it is simple in structure, for the peace of product to be checked
It is quick precisely, it can be achieved that more of one man operation is detected work to set position, for enterprise improve work efficiency and saved at
This.
Description of the drawings
