Description
Technical Field
The application relates to a bearing assembly field especially relates to a bearing seal ring pressure equipment mechanism.
Background
The bearing is divided into an open bearing and a sealed bearing according to whether a sealing element exists or not, and the sealing element of the sealed bearing has three structures of a dustproof cover, a sealing ring and a composite cover; the sealing ring is formed by bonding rubber and a framework together through vulcanization treatment and finally pressing the rubber and the framework on a bearing through a sealing pressing die. One of the most important performances of the bearing with the sealing ring is the sealing performance, but the main influencing factors of the sealing performance are embodied in the sealing structure, the manufacturing precision and the press-fitting quality, and the press-fitting quality is ensured by press-fitting equipment and a press-fitting mold.
The cover core of getting of the ordinary pressure equipment mould of rubber seal is straight tube-shape, its external diameter size is decided by sealing washer internal diameter size, generally more than the sealing washer internal diameter size big 0.2mm, must guarantee to get the cover core and the sealing washer does not drop when snatching the sealing washer, often can meet the circumstances of getting cover core external diameter size undersize or oversize in the use, get cover core size undersize can lead to the sealing washer to snatch not to go out or snatch the sealing washer slope and lead to off-centre, it can lead to the sealing washer to warp to get cover core external diameter size oversize, the sealing washer damage phenomenon appears even. The size of the press-fitting part of the lower end face of the outer sleeve of the common press-fitting die for the rubber sealing ring is not emphasized in the manufacturing process, the size and the precision of a press-fitting step are unqualified in the manufacturing process, the press-fitting of the sealing ring is not in place due to the fact that the height of the press-fitting step is too small, and the sealing ring falls off in use; the excessive height of the press-fitting step can cause the overpressure of the sealing ring, and the surface deformation phenomenon of the sealing ring occurs; the precision of the press-fitting part is unqualified, so that the appearance quality of the press-fitted sealing ring such as deformation, eccentricity and the like is unqualified. Meanwhile, the size of the groove for taking the cover core and installing the spring in the mold is overlarge, and the spring in the cover core is taken at will, so that the problems of elasticity, positioning and the like of the spring are not concerned. And the distance between the outer sleeve and the cap removing core is also optional. The manufacturing and design problems of the press-fitting dies can cause the phenomena of improper press-fitting, deformation, eccentricity, flanging and the like of the sealing ring after the bearing of the sealing ring is pressed. The defective phenomena have a certain proportion during production, a part of unqualified products can be removed in subsequent appearance detection, but the defective products cannot be completely removed, the appearance detection efficiency is slowed down, the appearance detection difficulty is increased, and the sealing performance of the sealing bearing is finally influenced.

The first embodiment is as follows:
the structure of the bearing seal ring press-fitting mechanism of the present embodiment includes, as shown in fig. 1 to 4:
the cap taking device comprises an outer sleeve 1, a cap taking core 2, a spring 3, a cover plate 4 and a connecting rod 5;
the spring 3 is sleeved on the connecting rod 5, the first end of the spring 3 is fixed with the connecting rod 5, the spring 3 is embedded in the cap taking core 2, and the second end of the spring 3 is fixed with the cap taking core 2;
the outer sleeve 1 is sleeved on the cap taking core 2, and the cap taking core 2 can linearly move in the outer sleeve 1 along the axial direction of the outer sleeve 1;
the cover plate 4 is fixed at the first end of the outer sleeve 1, the first end of the connecting rod 5 penetrates through the cover plate 4 and extends outwards, the connecting rod 5 is fixed with the cover plate 4, and when the connecting rod 5 is pushed, the outer sleeve 1 and the cover plate 4 are driven to move together and extrude the spring 2;
the inner wall of the outer sleeve 1 is provided with a first protrusion 101, the outer wall of the cap taking core 2 is provided with a second protrusion 201, and the first protrusion 101 and the second protrusion 201 are mutually abutted when the cap taking core 2 linearly moves in the outer sleeve 1 along the axial direction of the outer sleeve 1, so that the movement stroke of the cap taking core 2 in the outer sleeve 1 is limited, and the cap taking core 2 is prevented from sliding out of the outer sleeve 1 from the second end of the outer sleeve 1;
the positional relationship between the cap removing core 2 and the outer sleeve 1 is always kept in a state where the first projection 101 and the second projection 201 are abutted against each other by the urging force of the spring 3 itself.
The cover removing core 2 comprises a cover removing part 21 and a fitting part 22; the cover part 21 and the embedding part 22 are fixed into a whole, and the spring 3 is embedded in the embedding part 22;
when the spring 3 is extruded, because the outer diameter of the spring 3 is provided with the embedded part 22, and the inner diameter is limited by the connecting rod 5, the displacement deformation of the spring 3 caused by extrusion can be effectively avoided, and the unbalance stress of the cover taking core 2 can be avoided.
The second end of the cover taking part 21 is provided with an inner ring boss 23 embedded with the bearing inner ring, and the inner ring boss 23 is embedded into the bearing inner ring to play a role in positioning the whole press-mounting mechanism when in use.
The cover taking part 21 sequentially comprises a first section 24, a second section 25, a third section 26, a fourth section 27 and a fifth section 28 along the axial extension direction of the inner ring boss 23;
the outer diameter of the first section 24 is greater than the inner diameter of the seal ring; the outer diameter of the third section 26 is smaller than the inner diameter of the seal ring;
the second section 25 is a transition section between the first section 24 and the third section 26, and the transition section is from the first section 24 to the third section 26 from large to small;
