Abstract
The utility model discloses an installation tool for O-shaped sealing rings on a multistage shaft body. A cylinder with one end being opened and the other end being spherical is adopted; the inner diameter of the cylinder is larger than the maximum diameter of the multistage shaft body; a plurality of O-shaped sealing rings to be installed are sheathed in the outer ring of the cylinder in sequence according to installation order, later the cylinder is sheathed on the multistage shaft body and moved to the grooved part of the multistage shaft body; and then the O-shaped sealing rings sheathed on the cylinder are moved out in sequence and installed in the grooves. The installation tool can conveniently implement the installation of the O-shaped sealing rings on the multistage shaft body, improve the installation efficiency, prevent the O-shaped sealing rings from being damaged and deformed during installation process and ensuring the service life of the O-shaped sealing rings as well as the sealing effect of equipment.
Description
Technical field
The utility model relates to O-ring seals erecting tools on a kind of multistage axis body.
Background technology
Be interval with a plurality of grooves on the axis body of some equipment and constitute multistage axis body, as shown in Figure 1, be provided with O-ring seals in each groove 5 of multistage axis body 4, be used to seal the corresponding site on the axis body, needs according to equipment, each groove 5 diameter on axis body 4 is different, therefore is equipped with the O-ring seals of different-diameter; In maintenance of equipment or when examining surely, need dismounting or change a plurality of O-ring seals on the multistage axis body; Usually on multistage axis body, during the dismounting O-ring seals, use a word bottle opener that a plurality of O-ring seals are provoked in groove, shift out or move into along axis body successively then; Obviously the O-ring seals that is positioned at the axle head inboard needs could to dismantle or install through a plurality of grooves, the dismounting of O-ring seals is extremely inconvenient on the multistage axis body like this, dismounting efficient is low, very easily damage the new clothes O-ring seals, cause the O-ring seals distortion or influence service life, serious situation causes equipment to re-assembly the back seal failure.
Summary of the invention
Technical problem to be solved in the utility model provides O-ring seals erecting tools on a kind of multistage axis body, this instrument of utilization can conveniently be implemented the installation of O-ring seals on the multistage axis body, improved installation effectiveness, avoid the damage and the distortion of O-ring seals in the installation process, guaranteed the service life of O-ring seals and the sealing effectiveness of equipment.
For solving the problems of the technologies described above, the O-ring seals erecting tools is a cylinder on the multistage axis body of the utility model, described cylinder one end opening, and the other end of described cylinder is a sphere, the internal diameter of described cylinder is greater than the maximum gauge of multistage axis body.
Because the O-ring seals erecting tools has adopted technique scheme on the multistage axis body of the utility model, promptly adopting an end opening, the other end is the cylinder of sphere, and the internal diameter of cylinder is greater than the maximum gauge of multistage axis body; A plurality of O-ring seals that need are installed are inserted in this cylinder outer ring successively by order is installed, and then cylinder are placed on the multistage axis body, and mobile cylinder is to the groove of multistage axis body, and the O-ring seals that will be placed in successively on the cylinder shifts out and be installed in the groove; This instrument can conveniently be implemented the installation of O-ring seals on the multistage axis body, has improved installation effectiveness, has avoided the damage and the distortion of O-ring seals in the installation process, has guaranteed the service life of O-ring seals and the sealing effectiveness of equipment.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the structural representation of multistage axis body,
Fig. 2 is the structural representation of O-ring seals erecting tools on the multistage axis body of the utility model,
Fig. 3 utilizes this instrument that the schematic diagram of O-ring seals is installed.
The specific embodiment
As shown in Figure 2, the O-ring seals erecting tools is a cylinder 1 on the multistage axis body of the utility model, described cylinder 1 one ends 2 openings, and the other end 3 of described cylinder 1 is a sphere, the internal diameter of described cylinder 1 is greater than the maximum gauge of multistage axis body.
As shown in Figure 3, when on multistage axis body 4, O-ring seals 6 being installed, cylinder 1 outer ring that a plurality of O-ring seals 6 that need are installed are inserted in this instrument successively by the installation order, cylinder 1 is placed on the multistage axis body 4 then, mobile cylinder 1 is to groove 5 places of multistage axis body 4, and the O-ring seals 6 that will be placed in successively on the cylinder 1 shifts out and is installed in the groove 5; So conveniently realize the installation of O-ring seals on the multistage axis body, overcome the defective of conventional mounting method.
The cylinder of this instrument can adopt nylon rod processing to make, and it is simple in structure, and is easy to operate, and being inserted in of minor diameter O-ring seals is convenient in the design of cylinder one end sphere; This instrument of employing makes the installation effectiveness of O-ring seals improve 50%, and the spoilage of O-ring seals drops to 0% by original 10%, has avoided owing to the O-ring seals defective mounting causes seal failure.
Claims (1)
