Technical Field

[0001] This utility model relates to the field of mechanical disassembly, and in particular to a special tool for quickly and advancedly disassembling bearing outer sleeves. Background Technology

[0002] When inspecting or recycling bearings, it is necessary to disassemble the bearing outer sleeve, which requires the use of bearing disassembly equipment.

[0003] Traditional bearing outer casing removal equipment includes pry bars, chisels, hammers, and hot-fire cutting tools. These tools cannot reliably position the inner ring of the bearing during the removal of the bearing outer casing. Consequently, the bearing is not properly restrained during the removal process, making it difficult to transmit force stably and thus hindering the removal of the bearing outer casing. Therefore, this solution proposes a fast and advanced specialized tool for removing bearing outer casings to address the aforementioned problems. Utility Model Content

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model provides, for example Figure 1-4 The tool shown is a special tool for quickly and advancedly disassembling bearing outer sleeves, including a U-shaped connecting rod 1, an impact mechanism 5 at the top of the U-shaped connecting rod 1, a support plate 2 at the bottom of the U-shaped connecting rod 1, multiple arc-shaped pins 3 symmetrically arranged at both ends of the support plate 2 along the horizontal direction, and a storage cavity 6 opened in the middle of the support plate 2.

[0030] It should be noted that the diameter of the support plate 2 needs to be smaller than the diameter of the inner ring of the bearing to be disassembled, so that the support plate 2 can be placed in the direction of the inner diameter of the bearing outer ring. Then, the inner ring of the bearing is supported by the outward expansion of the arc-shaped ejector pin 3 at the support plate 2.

[0031] Also includes:

[0032] The rotary adjustment mechanism 4 is rotatably connected to the support plate 2. The rotary adjustment mechanism 4 is used for the horizontal adjustment of multiple arc-shaped ejector pins 3. The rotary adjustment mechanism 4 and the arc-shaped ejector pins 3 are driven within the storage cavity 6.

[0033] Specifically, the rotation adjustment mechanism 4 includes:

[0034] Rotating rod 402 is vertically connected to the middle of support plate 2. A toggle gear 404 is provided at the bottom of rotating rod 402 and is rotatably connected to storage cavity 6.

[0035] The toothed plate 405 is fixedly connected to one end of the arc-shaped ejector pin 3. The toothed plate 405 is slidably inserted into the receiving cavity 6, and the toothed side of the toothed plate 405 meshes with the outer wall of the actuating gear 404.

[0036] Furthermore, a rotating button block 401 is fixedly connected to the top of the rotating rod 402, and a rotating bearing 403 is sleeved on the outer wall of the rotating rod 402, and the rotating bearing 403 is located at the intersection of the rotating rod 402 and the support plate 2.

[0037] It should be noted that the rotating bearing 403 enables the rotating rod 402 to rotate more stably and ensures that the rotating rod 402 rotates in a vertical position, thereby ensuring stable meshing between the outer wall of the actuating gear 404 and the tooth side of the tooth plate 405.

[0038] The end of the arc-shaped ejector pin 3 away from the support plate 2 is set in an arc shape, and the toothed plate 405 is set on the side of the arc-shaped ejector pin 3. Multiple sets of toothed plates 405 are arranged symmetrically in the horizontal longitudinal direction along the outer wall of the actuating gear 404.

[0039] The blocking mechanism 7 is located at the intersection of the arc-shaped ejector pin 3 and the support plate 2. The blocking mechanism 7 is used for the sliding support of the arc-shaped ejector pin 3 and is located in the storage cavity 6.

[0040] Specifically, the blocking mechanism 7 includes:

[0041] The blocking groove 701 is formed on the inner walls of both sides of the storage cavity 6;

[0042] The blocking sliders 702 are fixedly connected to both sides of the arc-shaped ejector pin 3, and the blocking sliders 702 are slidably inserted into the blocking grooves 701.

[0043] It should be noted that, with the sliding cooperation of the blocking groove 701 and the blocking slider 702, the arc-shaped ejector pin 3 can move stably in the horizontal direction. At the same time, with the structural cooperation of the two, the toothed plate 405 can maintain sliding stability as it slides with the arc-shaped ejector pin 3, thereby ensuring that the toothed plate 405 and the actuating gear 404 mesh stably with each other.

[0044] Specifically, impact mechanism 5 includes:

[0045] The blocking plate 501 is fixedly sleeved on the top of the U-shaped connecting rod 1;

[0046] Impact hammer 502 is slidably sleeved on the outer wall of U-shaped connecting rod 1.

[0047] Furthermore, the top of the U-shaped connecting rod 1 is set as a straight rod body, and the bottom of the U-shaped connecting rod 1 is set as a U-shaped rod body. The impact hammer 502 is slidably inserted into the outer wall of the straight rod body and located below the blocking plate 501.

[0048] It should be noted that when using this device to disassemble the outer ring of the bearing, first, keep the support plate 2 horizontal and insert it into the inner ring of the bearing to be disassembled. Then, rotate the rotary knob 401 clockwise. At this time, the rotating rod 402 drives the actuating gear 404 to rotate. Under the meshing transmission, the toothed plate 405 is driven to move the arc-shaped ejector pin 3 away from the support plate 2. The arc end of the arc-shaped ejector pin 3 presses against the inner ring of the bearing. Then, hold the top of the U-shaped connecting rod 1 and use the impact hammer 502 to strike the blocking plate 501 upward. The impact force is transmitted through the blocking plate 501 and the U-shaped connecting rod 1 to the support plate 2 and the arc-shaped ejector pin 3, thereby removing the outer ring of the bearing.

[0049] After removing the bearing outer ring, rotate the rotary knob 401 counterclockwise. At this time, the arc-shaped pin 3 moves towards the support plate 2, thereby removing the support plate 2 from the inner ring of the bearing.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
