[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0032] Existing bearing stripping uses a hydraulic press. During the disassembly process, the pulley housing and the pulley body are first fixed with a wrench or other fixing tools to avoid unnecessary rotation during disassembly. Then, the hydraulic press is used to gradually separate the bearing from the plastic. This method of stripping the bearing using a hydraulic press is difficult to quickly place and position the bearing, the bearing is not evenly stressed, and the bearing is easily damaged.

[0033] In order to solve the above technical problems, this embodiment provides a bearing stripping tool, please refer to Figure 1 and Figure 2 As shown, Figure 1 It is a three-dimensional diagram of the bearing stripping tool in the embodiment, Figure 2 It is the front view of the bearing stripping tool in the embodiment when stripping the bearing.

[0034] A bearing stripping tool in this embodiment includes: a base 1, a support block 2 and a pressing mechanism 3.

[0035] The base 1 is provided with a guide structure 10 , which is a slide groove 100 or a slide rail, and is provided with a stripping position and a replacement position.

[0036] The base 1 is used to support the pressing mechanism 3 and the supporting block 2, and can be placed on a workbench when in use.

[0037] The support block 2 is supported on the base 1 and includes a positioning portion 21. The positioning portion 21 is located at the top of the support block 2 and is used to position the bearing 5. A feed hole 22 is provided in the middle of the positioning portion 21. The support block 2 and the guide structure 10 are slidably connected between the stripping position and the replacement position.

[0038] The support block 2 is used to support the pulley assembly 4 and locate the position of the bearing 5. The feed hole 22 is used to make way for the stripped bearing 5. The positioning portion 21 can directly locate the position of the bearing 5, or it can locate the position of the bearing 5 indirectly by positioning the pulley.

[0039] The pressing mechanism 3 includes a mounting frame 31 , a pressing drive mechanism 32 and a circular shaft 33 . The mounting frame 31 is arranged on the base 1 , the pressing drive mechanism 32 is connected to the mounting frame 31 , and the circular shaft 33 is located above the supporting block 2 and connected to the pressing drive mechanism 32 .

[0040] The above-mentioned pressing mechanism 3 is used to press down the bearing 5 to separate the bearing 5 and the pulley assembly 4, wherein when the support block 2 is located at the stripping position, the circular shaft 33 and the bearing 5 on the positioning portion 21 are relative to each other, and the relative position means that the axis of the circular shaft 33 and the bearing 5 on the positioning portion 21 coincide with or are nearly coincident, so that the force exerted by the circular shaft 33 on the bearing 5 is evenly distributed on the bearing 5, and when the support block 2 is located at the replacement position, it is located on the outside of the circular shaft 33 in a top-down view.

[0041] When the bearing stripping tooling of the above technical solution is working, first slide the support block 2 to the replacement position. At this time, the support block 2 is located on the outside of the circular shaft 33 from a top-down angle, and the circular shaft 33 will not interfere with placing the pulley assembly 4 on the support block 2, making the operation of placing the pulley assembly 4 more convenient; then, the bearing 5 is positioned by the positioning portion 21 on the support block 2, so that the position of the bearing 5 is fixed relative to the support block 2; then, slide the support block 2 to the stripping position, at this time, the circular shaft 33 is relative to the bearing 5 on the positioning portion 21, and the pressing mechanism 3 drives the circular shaft 33 to press down the bearing 5 in the pulley assembly 4 with the mounting frame 31 as support through the pressing drive mechanism 32, and strip the bearing 5. The stripped bearing 5 falls into the discharge hole 22; finally, slide the support block 2 to the replacement position, take out the bearing 5, and replace the next pulley assembly 4 to perform the next bearing 5 stripping operation. It can be seen that the bearing stripping tooling of the above technical solution makes the placement and removal of the pulley assembly 4 more convenient and the positioning of the bearing 5 faster and more accurate during the entire stripping process of the bearing 5, which is beneficial to uniform force on the bearing 5 during stripping, reduces the risk of damage, and improves the yield rate.

[0042] Exemplarily, the guide structure 10 is a slide groove 100, and the support block 2 includes a slider 23. The slider 23 is located at the bottom of the support block 2 and is slidably disposed in the slide groove 100. The support block 2 slides along the slide groove 100 through the slider 23. The slide groove 100 provides a clear moving path for the slider 23, ensuring that the support block 2 can slide in a predetermined direction.

[0043] Furthermore, the support block 2 includes a support portion 24, which is located above the slider 23 and supported on the base 1. The support portion 24 is the main load-bearing part of the support block 2. It is in direct contact with the base 1 to ensure that the support block 2 can be stably placed on the base 1 when sliding and transmit the supporting force.

[0044] Exemplarily, the guide structure 10 is a slide rail, the support block 2 is slidably connected to the slide rail, and is supported on the base 1 through the slide rail.

[0045] In one embodiment of the above-mentioned positioning portion 21, the positioning portion 21 is a circular annular convex portion, and the circular annular convex portion is used to position the inner ring of the pulley assembly 4. When the pulley assembly 4 is installed on the support block 2, its inner ring will fit tightly with the circular annular convex portion of the positioning portion 21, thereby achieving accurate positioning. This positioning method not only improves the installation accuracy of the pulley assembly 4, but also helps to prevent the pulley from shifting or shaking during the process of stripping the bearing 5, thereby ensuring the positioning stability and reliability of the bearing 5.

[0046] Furthermore, a frustum surface is provided on the outer side of the annular convex portion, and the radius of the frustum surface gradually decreases from bottom to top. The gradually decreasing radius helps to provide a guiding effect when the pulley assembly 4 is installed, so that the inner ring can cooperate with the annular convex portion more smoothly to achieve precise positioning. Secondly, the design of the frustum surface can increase the contact area between the support block 2 and the pulley assembly 4, thereby improving the stability and carrying capacity of the support. In addition, the inclined design of the frustum surface can also help to disperse the pressure and friction generated by the pulley during operation, thereby extending the service life.

[0047] In another embodiment of the positioning portion 21, the positioning portion 21 is provided with a positioning groove, the shape of which is the same as the outer contour of the pulley assembly 4. During positioning, the pulley assembly 4 is placed in the positioning groove.

[0048] Exemplarily, the discharge hole 22 is a through hole, and the support block 2 is provided with a clearance hole 25. The clearance hole 25 is connected to the discharge hole 22 and penetrates the support block 2 in the sliding direction of the support block 2. The bearing 5 can continue to move downward through the discharge hole 22 without accumulating or blocking in the discharge hole 22, which ensures the continuity of the stripping and collection process of the bearing 5 and improves work efficiency. In addition, the design of the clearance hole 25 on the support block 2 further enhances this collection and processing mechanism. The clearance hole 25 is connected to the discharge hole 22 and penetrates the support block 2 in the sliding direction of the support block 2. In this way, after the bearing 5 falls from the discharge hole 22, it can continue to slide out along the clearance hole 25 without being hindered by the support block 2.

[0049] Exemplarily, the discharge hole 22 is a blind hole, and the bearing 5 is temporarily stored in the blind hole after being peeled off, and is taken out when the support block 2 slides to the replacement position.

[0050] In order to improve the stability of the pressing action of the circular shaft 33, the pressing mechanism 3 also includes a reset component, which includes a guide shaft 34, a reset spring 35 and a guide plate 36. The guide plate 36 is connected to the pressing drive mechanism 32 and rises and falls synchronously with the circular shaft 33. The guide shaft 34 is connected to the base 1 and is vertically movably arranged on the guide plate 36. In the figure, the number of guide shafts 34 is 4. The reset spring 35 is sleeved on the outer side of the guide shaft 34 and is located between the guide plate 36 and the base 1. The addition of the reset component enables the pressing mechanism 3 to automatically reset after completing the pressing action, thereby improving the convenience and efficiency of the operation. At the same time, the coordinated work of the guide shaft 34, the reset spring 35 and the guide plate 36 also ensures the stability and reliability of the entire pressing mechanism 3.

[0051] Exemplarily, the pressing drive mechanism 32 is a hydraulic drive mechanism, such as a manual hydraulic cylinder.

[0052] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
