DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0021] Combination Figure 1 A bearing inner ring disassembly tool comprises a bracket 1, a disassembly component 2 for pulling out the bearing inner ring is arranged on one side of the bracket 1, and an adjustment component 3 for adjusting the inclination angle of the disassembly component 2 is arranged between the bracket 1 and the disassembly component 2.

[0022] The utility model is further described below in conjunction with embodiments.

[0023] Embodiment 1:

[0024] See also Figure 1-Figure 4 The adjusting component 3 includes a connecting rod 31 and an electric push rod 32 arranged on one side of the bracket 1, and a fixing ring 33 hinged at one end of the connecting rod 31 and the telescopic end of the electric push rod 32. The interior of the fixing ring 33 is connected to the outer surface of the decomposition component 2. The outer surface of the fixing ring 33 is hinged with a spring telescopic rod 34. The fixed end of the spring telescopic rod 34 is also provided with the bracket 1. The decomposition component 2 is installed inside the fixing ring 33, and then the fixing ring 33 is connected to the bracket 1 through the connecting rod 31, the electric push rod 32 and the spring telescopic rod 34, so that the decomposition component 2 is perpendicular to the bearing, and then the inclination angle of the decomposition component 2 is changed by the telescopic movement of the electric push rod 32, so that it is located on the same vertical line as the inner ring of the bearing at a specific angle, thereby increasing the scope of use and being more practical.

[0025] The decomposition component 2 includes a cylinder 21 inserted into the interior of the fixing ring 33, a threaded cylinder 22 arranged on the upper surface of the cylinder 21, and a threaded rod 23 threadedly connected to the interior of the threaded cylinder 22. A disc 24 is fixedly installed at the bottom of the threaded rod 23. A groove 25 is provided inside the disc 24. There are three groups of grooves 25. A rotating shaft 26 is provided inside each group of grooves 25. A pull-out block 27 is sleeved on the outer surface of the rotating shaft 26. A spring 28 is provided on one side of the pull-out block 27. One end of the spring 28 is fixedly connected to the outer surface of the threaded rod 23 to contact the bottom of the cylinder 21 with the upper surface of the bearing. At this time, the three groups of pull-out blocks 27 are all located inside the cylinder 21, and the spring 28 is compressed. Then the threaded rod 23 is rotated to move the pull-out block 27 downward, and the spring 28 is gradually reset, so that not only the pull-out block 27 enters the inner ring of the bearing, but also the lower ends of the three groups of pull-out blocks 27 expand outward. Because one side of the pull-out block 27 is shaped as a hook block, it can hook the inner ring of the bearing, thereby facilitating subsequent pull-out.

[0026] A turntable 4 is fixedly mounted on the upper end of the threaded rod 23 for easy holding and operation.

[0027] A placement table 5 is arranged between the two groups of brackets 1, and a clamping assembly 6 is arranged inside the placement table 5. The clamping assembly 6 includes a motor A61 arranged on one side of the placement table 5, a double-threaded rod 62 fixedly installed at the output end of the motor A61, and a clamping block 63 threadedly connected to the positive thread and the negative thread on the outer surface of the double-threaded rod 62. The bearing is located between the two groups of clamping blocks 63, and a fixing block 64 is provided in the center sleeve of the double-threaded rod 62. The bottom of the fixing block 64 is fixedly connected to the upper surface of the placement table 5. The bearing is placed between the two groups of clamping blocks 63, and then the two groups of clamping blocks 63 are driven by the motor A61 to move simultaneously along the positive thread and the negative thread direction of the outer surface of the double-threaded rod 62, thereby clamping the bearing for easy subsequent removal.

[0028] One side of the two groups of clamping blocks 63 is provided with an elastic pad 631 to prevent the outer surface of the bearing from being damaged during the extraction process.

[0029] A lifting assembly 7 is provided on the upper surface of the placement table 5. The lifting assembly 7 includes a motor B71 arranged inside the placement table 5, a screw rod 72 fixedly installed at the output end of the motor B71, and a connecting block 73 threadedly connected to the outer surface of the screw rod 72. There are two groups of connecting blocks 73, and a guide rod 74 is passed through the center of one group of connecting blocks 73. One side of the two groups of connecting blocks 73 is fixedly connected to one side of the bracket 1. When the bearing is fixed and the pull-out block 27 also hooks the inner ring of the bearing, the connecting block 73 is driven by the motor B71 to move up along the outer surface of the screw rod 72, so the bracket 1 also moves up, thereby driving the decomposition assembly 2 to move up, so that the inner ring of the bearing can be pulled out.

[0030] Specifically, the bearing is placed between two sets of clamping blocks 63, and then the motor A61 drives the two sets of clamping blocks 63 to move centrally along the positive thread and negative thread directions of the outer surface of the double-threaded rod 62 at the same time, so as to clamp the bearing, and elastic pads 631 are provided on one side of the two sets of clamping blocks 63 to prevent damage to the outer surface of the bearing during the extraction process, and then according to the position of the inner ring of the bearing, the inclination angle of the decomposition component 2 is changed by the extension and contraction of the electric push rod 32, so that it is located on the same vertical line with the inner ring of the bearing at a specific angle, and then the motor B71 drives the connecting block 73 to move downward along the outer surface of the screw rod 72 , so the bracket 1 also moves down, so that the bottom of the cylinder 21 contacts the upper surface of the bearing. At this time, the three groups of pull-out blocks 27 are all located inside the cylinder 21, and the spring 28 is compressed. Then the threaded rod 23 is rotated to move the pull-out blocks 27 down, and the spring 28 is gradually reset, so that not only the lower ends of the three groups of pull-out blocks 27 enter the inner ring of the bearing, but also the lower ends of the three groups of pull-out blocks 27 expand outward, and because one side of the pull-out blocks 27 is shaped as a hook block, it can hook the inner ring of the bearing. Then, the motor B71 drives the connecting block 73 to move up along the outer surface of the screw rod 72, so the bracket 1 also moves up, thereby driving the decomposition component 2 to move up, so that the inner ring of the bearing can be pulled out.
