Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and in particular to a bearing dust cover pry tool. Background Technology

[0002] The main function of a bearing dust cover is to prevent dust and other external contaminants from entering the bearing, thereby protecting the bearing from damage and extending its service life.

[0003] During the use of bearings, it may be necessary to pry open the bearing cover for various reasons. However, the existing prying methods generally involve applying a certain force to the dust cover to deform it and dislodge it from the bearing's locking groove. However, the force applied to the dust cover in this way is difficult to control, which may damage the dust cover or even other components of the bearing.

[0004] Therefore, a pry tool that can pry open the dust cover without damaging it is needed. Summary of the Invention

[0005] In order to solve the problem that existing methods of prying open bearing dust covers can easily damage the dust cover, this utility model provides a prying tool that can pry open bearing dust covers without causing damage.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a bearing dust cover prying tool, including a worktable, on which a pressure rod and a limiting body are placed coaxially. The limiting body is inserted into the inner ring of the bearing so that the bearing and the pressure rod are coaxial. The pressure rod includes a body and a pressure ring integrally disposed at the lower end of the body. The pressure ring is used to apply a downward force to the inclined surface of the dust cover so that the rolled edge of the dust cover is rolled towards the inner diameter of the bearing. A shell is fixed on the worktable. The top of the body extends through the shell and slides with the shell. A protruding ring is fixed on the body. A limiting ring is fixed inside the shell. A spring is disposed between the protruding ring and the limiting ring.

[0007] Furthermore: a mounting cover is detachably mounted on the top of the outer casing, the main body extends upward through the mounting cover, and the bottom of the mounting cover is used to abut against the top of the protruding ring.

[0008] Furthermore, the diameter of the pressure ring gradually increases as the distance from the bearing decreases.

[0009] Furthermore, the maximum diameter of the pressure ring is smaller than the inner diameter of the outer ring of the bearing.

[0010] Compared with the prior art, the advantages of this utility model are:

[0011] The pressure bar acts on the inclined plane of the dust cover, causing the dust cover to stretch downwards. This causes the rolled edge of the dust cover to deform, thus disengaging it from the bearing's locking groove and enabling the dust cover to be pried open. During this process, the spring acts as a buffer to cushion the downward pressure of the main body and controls the force applied to the dust cover by the pressure bar, thereby preventing damage to the dust cover to a certain extent. Furthermore, the presence of the spring allows the main body to automatically reset after completing one operation, facilitating the next prying operation. Attached Figure Description

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0017] like Figures 1 to 3As shown, a bearing dust cover prying fixture includes a worktable. A pressure rod 1 and a limiting body 2 are coaxially arranged on the worktable. The limiting body 2 is inserted into the inner ring of a bearing 4 to make the bearing 4 coaxial with the pressure rod 1. The pressure rod 1 includes a body 11 and a pressure ring 12 integrally disposed at the lower end of the body 11. The pressure ring 12 applies a downward force to the inclined surface of the dust cover 41, causing the rolled edge of the dust cover 41 to curl towards the inner diameter of the bearing 4. The pressure rod 1 applies pressure to the bearing 4. During this process, the limiting body 2 ensures the coaxiality of the bearing 4 and the pressure rod 1, guaranteeing the accuracy of the working process and preventing deviation between the pressure rod 1 and the bearing 4, thus avoiding work errors. The pressure ring 12 is used to press the dust cover 4... 1. The specific component applying pressure: When the pressure rod 1 is pressed down, the pressure ring 12 applies pressure to the dust cover 41, causing the rolled edge of the dust cover 41 to curl. Continuous pressure causes the rolled edge to disengage from the snap-fit ​​groove of the bearing 4, thereby achieving the effect of removing the dust cover 41. The diameter of the pressure ring 12 gradually increases as the distance from the bearing 4 decreases. This setting allows the pressure of the pressure ring 12 to apply an oblique force to the dust cover 41, thereby causing the rolled edge of the dust cover 41 to undergo slight deformation in an ideal form, so that it can be easily removed. The maximum diameter of the pressure ring 12 is smaller than the inner diameter of the outer ring of the bearing 4. This setting is used to ensure that the force applied by the pressure ring 12 to the dust cover 41 is in a moderate state, which can avoid damage to other components due to excessive force.

[0018] A housing 3 is fixed on the workbench. The top of the main body 11 extends through the housing 3 and slides within it. The housing 3 provides basic positioning for the pressure rod 1. A protruding ring 13 is fixed on the main body 11, and a limiting ring 31 is fixed inside the housing 3. The limiting ring 31 limits the movement distance of the main body 11, ensuring that the dust cover 41 and the retainer 42 of the bearing 4 remain at a certain distance after being pressed, thus protecting the retainer 42 to some extent. A mounting cover 32 is detachably installed on the top of the housing 3. The main body 11 extends upward through the mounting cover 32, and the bottom of the mounting cover 32 abuts against the top of the protruding ring 13. The protruding ring 13 and the limiting ring 31... A spring 33 is provided in the middle. The spring 33 can absorb part of the pressure when it is pressed down, thus playing a certain buffering role in the pressing process. This makes the pressure process of the pressure ring 12 on the dust cover 41 more gentle, avoiding damage to the bearing 4 due to excessive pressure. At the same time, the spring 33 can also automatically lift and reset the body 11 after the work is completed, thus saving the preparation work before the next bearing 4 cover prying work, which is conducive to improving work efficiency. The mounting cover 32 not only allows the body 11 to be successfully placed in the housing 3, but also limits the highest position of the convex ring 13 during the reset process, thus preventing the body 11 from falling out of the housing 3 and ensuring the integrity of the overall structure.

Any substitutions, modifications, or improvements to this technology that are easily conceived by those skilled in the art shall fall within the scope of protection of this utility model.
