The bearing and the sealing ring are installed between the upper and lower dies, so that the sealing ring is pressed into the bearing. Compared with manual die pressing, it is more convenient and efficient. In addition, the bearing sealing ring extrusion device is provided with a sliding sleeve 10 and a limiting sliding rod 11, so that the pressing plate 7 will not deviate when pressed down, and the upper die 9 and the lower die seat 5 are pressed vertically, and the sealing ring installation effect is better.

DETAILED DESCRIPTION

[0027] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-3 In the first embodiment, a bearing seal ring press-fitting device includes:

[0029] The crossbeam plate 20 is fixedly connected to the support frame 10;

[0030] A lifting plate 30 is lifted and disposed on the crossbeam plate 20;

[0031] The pressure sensor 40 is fixedly connected to the lower surface of the lifting plate 30;

[0032] A first base 52, fixedly connected to the stress surface of the pressure sensor 40;

[0033] The pressure cover 50 is detachably fixedly connected to the first base 52;

[0034] The second base 63 is fixedly connected to the support frame 10;

[0035] The positioning barrel 60 is detachably fixedly connected to the second base 63, and the opening end of the positioning barrel 60 has a plurality of lifting openings 61;

[0036] The movable plate 80 is movably disposed on the support frame 10;

[0037] A plurality of connecting rods 81 are respectively fixedly connected to the moving plate 80 and surround the positions of the positioning barrel 60 corresponding to the lifting opening 61 . The connecting rods 81 slide through the sliding holes 82 on the supporting frame 10 .

[0038] A plurality of pressing plates 70 respectively penetrate the lifting opening 61 and are detachably fixedly connected to the connecting rods 81 at corresponding positions.

[0039] This embodiment is implemented as follows:

[0040] When the present application is in use, the bearing is first placed in the positioning barrel 60, and then the sealing ring is pre-placed between the inner ring and the outer ring of the bearing. At this time, the movable plate 80 drives the pressure plate 70 to move vertically through the connecting rod 81, so that the pressure plate 70 can enter the lifting port 61 and exert downward pressure on the outer ring of the bearing, so that the vertical position of the bearing in the positioning barrel 60 is restricted. Then the lifting plate 80 moves downward, driving the pressure sensor 40, the first base 52, and the pressure cover 50 to move downward, so that the pressure cover 50 can exert pressure on the sealing ring, so that the sealing ring can be stuck between the inner ring and the outer ring of the bearing, and the pressure sensor 40 can sense the reaction force, thereby controlling the size of the applied pressure to avoid excessive or insufficient pressure;

[0041] When bearings of different diameters need to be press-fitted, the corresponding positioning barrel 60, pressure cover 50 and pressure plate 70 are replaced. The pressure plate 70 of the present application is mainly used to press the outer ring of the bearing without blocking the sealing ring; the pressure plate 70 in the present application is fixed to the connecting rod 81 by bolts, which is convenient for replacing pressure plates 70 of different lengths to adapt to positioning barrels 81 of different inner diameters.

[0042] Compared with the prior art, the present application has the advantages of improving the stability and precision of press-fitting and facilitating press-fitting of bearings of different sizes.
