DETAILED DESCRIPTION

[0030] The specific implementation of this embodiment is described below in conjunction with the accompanying drawings.

[0031] Please refer to Figure 1 The embodiment of the present application provides a bearing disassembly and assembly tool, including a sleeve 1, a screw hole 1-1 is opened at one end of the sleeve 1, and a centering screw 5 is movably installed in the screw hole 1-1, wherein the internal thread of the screw hole 1-1 is connected with the external thread of the centering screw 5, when the end of the centering screw 5 rotates, the centering screw 5 moves along the axial direction of the sleeve 1, when rotating forward, the centering screw 5 moves forward, and when rotating reversely, the centering screw 5 moves backward, and a guide head 4 and an installation cover plate 2 are movably installed in sequence through threads along the axial direction of the centering screw 5, and the installation cover plate 2-1 can be replaced after the installation cover plate 2 is unscrewed, and the centering screw 5 is movably arranged in the bearing mounting hole 15, and a bearing (not shown in the figure) is installed in the bearing mounting hole 15, and the bearing is provided with a bearing inner ring (not shown in the figure), and the guide head 4 is movably installed on the bearing inner ring.

[0032] A cylinder 3 is installed at one end of the disassembly cover 2-1 and the installation cover 2. The cross-section of the guide head 4 is conical. The top of the guide head 4 has a taper. The maximum diameter of the guide head 4 is smaller than the diameter of the inner ring of the bearing. The guide head 4 plays a guiding role. The conical surface of the guide head 4 allows the cylinder 3 at the rear to enter the inner ring of the bearing smoothly. The diameter of the cylinder 3 is slightly smaller than the diameter of the inner ring of the bearing.

[0033] When disassembling the bearing, after screwing the centering screw 5 into the sleeve 1, pass the centering screw 5 through the inner ring of the bearing, screw the guide head 4 and the removal cover plate 2-1 on the end of the centering screw 5 in sequence, then fix the sleeve 1 with one hand, and rotate the centering screw 5 in the positive direction with the other hand. The centering screw 5 drives the guide head 4 and the removal cover plate 2-1 to move toward the sleeve 1. During the movement, the guide head 4 and the cylinder 3 pass through the inner ring of the bearing. Because the maximum diameter of the removal cover plate 2-1 is smaller than the inner wall diameter of the sleeve 1, and the maximum diameter of the removal cover plate 2-1 is smaller than the inner diameter of the bearing mounting hole 15, the maximum diameter of the removed cover plate 2-1 is larger than the inner ring diameter of the bearing, so that the bearing enters the sleeve 1 together under the thrust of the removal cover plate 2-1.

[0034] When installing the bearing, after screwing the centering screw 5 into the sleeve 1, the centering screw 5 passes through the inner ring of the bearing, the guide head 4 and the cylinder 3 of the mounting cover plate 2 are inserted into the inner ring of the bearing, and then the combination of the three is placed at the right end of the bearing mounting hole 15 on the connecting rod 8. At this time, the cylinder 3 and the guide head 4 pass through the inner ring of the bearing. Then, one hand fixes the sleeve 1, and the other hand rotates the centering screw 5 in the opposite direction. At this time, the bearing moves toward the bearing mounting hole 15 driven by the guide head 4 and the mounting cover plate 2. Since the diameter of the mounting cover plate 2 is larger than the diameter of the bearing mounting hole 15, when the bearing enters the bearing mounting hole 15, the mounting cover plate 2 is blocked on one side of the bearing mounting hole 15. At this time, the mounting cover plate 2 does not move, and the guide head 4 inside the bearing moves toward the sleeve 1 under the drive. Finally, the guide head 4 enters the sleeve 1, and the centering screw 5 completely loses the cooperation with the mounting cover plate 2, and the installation of the bearing is completed.

[0035] A screw head 5-1 is installed at the end of the centering screw 5 near the sleeve 1. The screw head 5-1 is smooth and has no threads. The length is 10 mm, which is convenient for the user to hold and rotate.

[0036] Please refer to Figure 2 The bearing mounting holes 15 are arranged at both ends of the connecting rod 8 .

[0037] Please refer to Figure 3 As shown in the figure, a narrow space operation window is formed in the area, and the connecting rod 8 is connected to the rocker 7 through a bearing, and a soldering iron driving motor 6 is installed at the end of the rocker 7.

[0038] Please refer to Figure 3 The bearing is arranged in the bearing mounting hole 15 through the bearing bolt 14, and the bearing bolt 14 passing through the bearing on the needle bearing mounting hole 15 of the connecting rod 8 is loosened to separate the connecting rod 8 from the rocker arm 7. At this time, the connecting rod 8 can rotate on the connecting shaft 10.

[0039] Please refer to Figure 3 The connecting shaft 10 is installed at the center of the connecting rod 8 through a fastening bolt 11. When preparing for disassembly and assembly, the fastening bolt 11 at the upper end of the connecting rod 8 needs to be loosened.

[0040] Please refer to Figure 4 The connecting rod 8 is installed in the equipment box 13 through the connecting shaft 10. When performing the preparation work before disassembly and assembly, it is necessary to remove the bolts on the wall panel inside the box and move the connecting rod 8 to a position suitable for operation. At this point, the preparation work is completed.

[0041] Working principle:

[0042] When removing the bearing, pass the centering screw 5 through the outside of the screw hole 1-1 at the bottom of the sleeve 1, and then connect the inner ring of the bearing with the threaded hole of the removal cover plate 2, rotate the screw head 5-1, so that the removal cover plate 2 drives the bearing to move toward the sleeve 1, and finally the removal cover plate 2 and the bearing enter the barrel of the sleeve 1 together.

[0043] When installing the connecting bearing, first pass the centering screw 5 from the left side of the screw hole 1-1 at the bottom of the sleeve 1, then pass it through the connecting bearing installation hole of the connecting rod 8, insert the guide head 4 and the cylinder 3 of the installation cover plate 2 into the inner ring of the bearing, and then place the combination of the three at the right end of the bearing installation hole on the connecting rod 8, rotate the screw head 5-1, so that the cover plate 2 is removed and drives the bearing to move toward the sleeve 1. When moving forward, due to the cone guiding effect of the guide head 4, the guide head 4 can drive the bearing to smoothly enter the bearing installation hole of the connecting rod 8. Due to the centering effect of the centering screw 5, the positioning of the disassembly and assembly tools is guaranteed to be consistent. When the installation cover plate 2 contacts the connecting rod 8, the bearing is installed in place.

[0044] Although the above description of the specific implementation of the present invention is combined with the accompanying drawings, it does not limit the scope of protection of the present invention.

[0045] Personnel should understand that, based on the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the protection scope of the utility model.
