Further, the method comprises the following steps of; the limiting shaft and the inserting shaft are integrally formed.

Further, the method comprises the following steps of; the width of the inserting sheet is the same as the diameter of the rear pressure ring.

Further, the method comprises the following steps of; and each group of the first grooves and the second grooves are positioned on the same circumference of the splicing shaft.

Further, the method comprises the following steps of; the sealing device further comprises a sealing piece, and the sealing piece is arranged at the top of the guide groove of the limiting shaft.

The invention has the beneficial effects that: the sealing ring is sleeved in the first groove and the second groove by utilizing the characteristic of large elasticity of the small-aperture deep-hole sealing ring, then the insertion sheet is pulled backwards to enable the sealing ring to be deformed in a butterfly shape, then the sealing ring is sent into the deep-hole sealing groove, and the insertion sheet is pressed, so that the sealing ring can be installed. The invention can also realize the simultaneous installation of a plurality of continuous sealing rings in the deep hole.

Detailed Description

Example 1:

as shown in fig. 1 and 6, the inner hole sealing ring mounting device comprises a main body mandrel and an insertion piece 1 inserted into the main body mandrel.

The main part dabber is equipped with guide way 5 along the axial direction, the main part dabber includes spacing axle 2 and grafting axle 3, spacing axle 2 is cylindrical step shaft, 2 front end diameters of spacing axle are less than the rear end diameter, grafting axle 3 is I shape structure, and its both ends are the same back clamping ring 31 and preceding clamping ring 32 of diameter, and the centre is connected by connection piece 33, terminal surface corner all adopts the arc transition before 31 preceding terminal surface of back clamping ring and preceding clamping ring 32, terminal surface before 31 fixed connection spacing axles of back clamping ring, 31 diameters of back clamping ring are less than 2 front end diameters of spacing axle, spacing
