[0025] Furthermore, a connecting plate 112 is fixed below the side of the fixed base 111 near the movable base 102. A threaded shaft 113 is installed and connected to the top of the connecting plate 112. The threaded shaft 113 is rotatably connected to the connecting plate 112, and the surface of the threaded shaft 113 is provided with threads.

[0026] Furthermore, one end of the threaded shaft 113 passes through the movable base 102 and is fixedly connected to a hexagonal turntable 104. The hexagonal turntable 104 is hexagonal, and the movable base 102 is rotatably connected to the threaded shaft 113.

[0027] It should be further explained that the hexagonal turntable 104 can be connected and rotated by a hexagonal wrench, and the rotation of the hexagonal turntable 104 drives the threaded shaft 113 to rotate. At this time, as the threaded shaft 113 rotates and is threadedly connected to the movable base 102, it can drive the movable base 102 to move horizontally. Meanwhile, the movable base 102 is slidably connected to the slide rail 103 through the connecting slot 116, which plays a guiding role in the movement and can maintain stable movement during the horizontal movement.

[0028] Furthermore, a fixing groove 110 is provided above the side of the fixed base 111 near the movable base 102, and the fixing groove 110 is flush with the mounting groove 117.

[0029] It should be further noted that the mounting groove 117 and the fixing groove 110 are on the same horizontal plane.

[0030] Further, the mobile base 102 and the fixed base 111 are provided with a circular fixed ring 107 at the top end, and a limiting groove 118 is arranged in the fixed ring 107, which is in communication with the fixed groove 110 and the mounting groove 117.

[0031] Further, the fixed ring 107 is provided with a limiting shaft 108 at the top end, which is in threaded connection with the limiting groove 118, and the lower end surface of the limiting shaft 108 can extend into the fixed groove 110 and the mounting groove 117.

[0032] It should be further explained that after the lower end of the limiting shaft 108 moves into the fixed groove 110 or the mounting groove 117, the connecting shaft 106 inserted and mounted can be limited and clamped.

[0033] Further, the limiting shaft 108 is fixedly connected with a hand plate 109 at the top end.

[0034] It should be further explained that the surface of the hand plate 109 is provided with annularly distributed notches, which facilitates the staff to hold and rotate it.

[0035] It should be further explained that after the staff holds and rotates the hand plate 109, the limiting shaft 108 can be driven and rotated, and then through the threaded connection between the limiting shaft 108 and the fixed ring 107, the limiting shaft 108 is driven to move downward.

[0036] Further, a stress monitor 114 is mounted on one side of the fixed base 111, and the sensing contact of the stress monitor 114 extends into the fixed groove 110; a warning light 115 is mounted on one side of the fixed base 111 below the stress monitor 114, and the warning light 115 is in signal connection with the stress monitor 114.

[0037] It should be further explained that when the stress monitor 114 senses that the stress changes greatly, the warning light 115 can be driven to change color through signal output, thereby playing a warning role.

[0038] When using the present scheme, first drive the bearing base 101 as a whole to the working position, at this time the connecting shaft 106 to be disassembled is placed in the inner ring of the installation groove 117, the side where the bearing 105 is installed is placed in the moving base 102 and away from the fixed base 111 side, then ensure that the connecting shaft 106 is tightly attached to the inner wall of the installation groove 117, the worker can drive the hand-held plate 109 to rotate by increasing the friction force by the annularly distributed slots on the surface of the hand-held plate 109, conveniently drive the hand-held plate 109 to rotate, since the hand-held plate 109 is fixedly connected with the limiting shaft 108, the rotation of the hand-held plate 109 will directly drive the limiting shaft 108 to rotate, and since the limiting shaft 108 is threadedly connected with the fixed ring 107, when the limiting shaft 108 rotates, the bottom side of the limiting shaft 108 gradually moves downward and enters into the installation groove 117 and limits and clamps the surface of the connecting shaft 106.

[0039] Then the worker drives the hexagonal turntable 104 to rotate by using a hexagonal wrench and the like, at this time the fixed ring 107 rotates and in turn drives the threaded shaft 113 to rotate, and since the threaded shaft 113 is threadedly connected with the moving base 102, it can in turn drive the moving base 102 to translate, and the moving base 102 is slidably connected with the slide rail 103 through the connecting slot 116, plays a moving guiding role and can keep stable during translation, and in turn enables one end of the connecting shaft 106 to stably move into the fixed groove 110 without angular deviation.

[0040] When the tail end of the connecting shaft 106 is completely entered into the fixed groove 110, the sensing contact of the stress monitor 114 contacts and abuts against the tail end of the connecting shaft 106 entered into the fixed groove 110, at this time the worker rotates the hand-held plate 109 at the top of the fixed base 111 and drives the limiting shaft 108 to enter into the fixed groove 110 to stably clamp the tail end of the connecting shaft 106.

[0041] Then the worker reversely rotates the hand-held plate 109 at the top of the moving base 102 and drives the limiting shaft 108 at the top of the moving base 102 to exit from part of the installation groove 117, loosens the connection of the connecting shaft 106, at this time the worker reversely rotates the hexagonal turntable 104, and in turn drives the moving base 102 to move away from the fixed base 111 side through the threaded connection between the hexagonal turntable 104 and the moving base 102, and makes one side of the moving base 102 contact and abut against the surface of the bearing 105, at this time since the moving base 102 continuously moves, the main part of the connecting shaft 106 has been stably kept in the device under the common limitation of the installation groove 117 and the fixed groove 110, and the further movement of the moving base 102 will make the side surface thereof tightly contact and press the surface of the bearing 105, so that the bearing 105 can be stably pushed away from the connecting shaft 106, thereby realizing the separation of the bearing 105.

[0042] If the bearing needs to be installed, first place the connecting shaft 106 in the installation groove 117, and make the bearing 105 previously sleeved to be located between the fixed base 111 and the moving base 102, at this time, the preliminary limiting of the connecting shaft 106 is carried out by rotating the handheld plate 109 to drive the limiting shaft 108 to move downward into the installation groove 117, then the moving base 102 is moved towards the fixed base 111 by rotating the hexagonal turntable 104, and the tail end of the connecting shaft 106 enters into the fixed groove 110, at this time, the handheld plate 109 is rotated to drive the limiting shaft 108 to further move downward into the fixed groove 110, and the tail end of the connecting shaft 106 is finally limited and clamped, then the clamping of the limiting shaft 108 at the top of the moving base 102 is loosened, and the hexagonal turntable 104 is continuously rotated, so that the side surface of the moving base 102 contacts with the bearing 105 and pushes it into the correct position, and the stable installation of the bearing is ensured.

[0043] During the whole disassembly and assembly process, the stress monitor 114 senses the contact head to monitor the stress change all the time. Once the stress is abnormally increased, such as the stress is abnormally increased due to the interference fit of the bearing being too tight or the installation position being improper, the stress monitor 114 will immediately change the color of the warning light 115 through the signal output to provide an intuitive warning signal for the staff, so as to timely adjust the operation strength or check the installation state, and avoid damaging the bearing or the device.
