Description

Technical Field

[0001] This utility model belongs to the field of bearing ring production, and in particular relates to a bearing ring surface treatment device. Background Technology

[0002] After grinding, the bearing races need to be cleaned to remove residual iron powder and other impurities. Vibration cleaning is a common method for cleaning bearing race surfaces. The equipment includes a tank containing cleaning fluid, with a vibrating cylinder inside. After grinding, the bearing races are placed inside the vibrating cylinder, and the vibration causes the bearing races to collide with the cleaning fluid, thus cleaning the surface of the bearing races.

[0003] However, in vibration cleaning methods, bearing races are typically stacked directly inside the vibratory drum. This leads to the accumulation of cleaning fluid at the stacked areas, which contains impurities washed off the bearing race surfaces, thus affecting surface cleaning quality. Even when the bearing races are placed flat inside the vibratory drum, small, lightweight bearing races can still roll and shift during vibration. When the bearing race's axis of displacement is horizontal, cleaning fluid accumulates in low-lying areas on its inner surface, affecting the cleaning quality of the inner surface. Furthermore, collisions between bearing races during vibration cause surface wear, affecting the subsequent use of the bearing race assembly machine. Utility Model Content

[0004] In view of this, the present invention aims to provide a bearing ring surface treatment device to improve the surface cleaning quality of bearing rings and solve the problem of surface damage during vibration cleaning of bearing rings.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A bearing ring surface treatment device includes a basket with a mesh-like sidewall and a bottom wall. A support rod is provided inside the basket, and a first vertical rod is provided on one side wall of the basket corresponding to the support rod. One end of the support rod is fixedly connected to the first vertical rod, and the other end of the support rod is a free end for threading bearing rings. Several bearing rings are sequentially threaded and hung on the support rod. A detachable separator is provided between every two adjacent bearing rings on the support rod.

[0007] The isolation component includes a tube movably mounted on a support rod, and several limiting rods arranged radially and outwardly on the tube, with the limiting rods evenly distributed circumferentially.

[0008] Furthermore, the tube includes a first tube body and a second tube body arranged sequentially, the first tube body and the second tube body have the same inner and outer diameters, the length of the second tube body is greater than the length of the first tube body, and the limiting rod is arranged at the connection between the first tube body and the second tube body.

[0009] The bearing ring is fitted onto the second tube body.

[0010] Furthermore, the first tube body, the second tube body, and the limiting rod are all fitted with rubber sleeves.

[0011] Furthermore, a limiting rod is provided on the pipe, and the length of the limiting rod is such that after the isolation piece is fitted onto the support rod, when the limiting rod is in a horizontal state, the outer end of the limiting rod abuts against the end face of the bearing ring mounted on the second pipe body.

[0012] Furthermore, the support rod is provided with an isolation element at the end where it is fixed to the side wall of the basket 1, which isolates the innermost bearing ring from the side wall of the basket.

[0013] Furthermore, a limiting plate is provided at the free end of the support rod inside the basket. The limiting plate includes an outer frame and a mesh screen provided inside the outer frame. An avoidance groove corresponding to the support rod is opened at the bottom end of the limiting plate.

[0014] The corresponding support rods of the basket are provided with second vertical rods on the left and right side walls of the corresponding limiting plates. The side of the second vertical rod facing inward has a vertical groove. The left and right frames of the limiting plates are movably inserted into the two grooves, and the free end of the support rod passes through the clearance groove.

[0015] Furthermore, the support rod has an isolation element between the outermost bearing ring and the limiting plate on which it is mounted.

[0016] Furthermore, the support rod is inclined, with its free end at the high end.

[0017] Compared with the prior art, the bearing ring surface treatment device of this utility model has the following advantages:

[0018] (1) In this utility model, the surface of the bearing ring is cleaned by hanging, and after hanging, each two adjacent bearing rings are separated by a separator, so that each bearing ring is relatively independent in the basket, which improves the surface cleaning quality of the bearing rings and prevents the bearing rings from being damaged by mutual collision during the vibration cleaning process.

[0019] (2) In this utility model, the support rod for mounting the bearing ring is inclined, so that the mounted bearing ring is inclined, preventing the cleaning fluid from depositing on the inner surface of the bearing ring and improving the surface cleaning effect of the bearing ring.

[0020] (3) In this utility model, the adjacent bearing rings are isolated by the limiting rod of the isolation component. The limiting rod and the bearing rings are in line contact.

[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] like Figure 1 , Figure 2As shown, a bearing ring surface treatment device includes a basket 1 with a mesh-like sidewall and a bottom wall. A support rod 5 is inclinedly arranged inside the basket 1. A first vertical rod 101 is provided on one side wall of the basket 1 corresponding to the support rod. One end of the support rod 5 is connected and fixed to the first vertical rod 101, and the other end of the support rod 5 is a free end, a high end, used for threading bearing rings 3. Several bearing rings 3 are sequentially threaded and hung on the support rod 5. A detachable separator 2 is provided between every two adjacent bearing rings 3 on the support rod 5, and a separator 2 is also provided at the end of the support rod 5 that is fixed to the side wall of the basket 1 to isolate the innermost bearing ring 3 from the side wall of the basket 1. A limiting plate 6 is provided at the free end of the corresponding support rod 5 inside the basket 1 to prevent the bearing ring 3 from falling off the support rod 5 during vibration cleaning. A separator 2 is provided between the outermost bearing ring 3 on the support rod 5 and the limiting plate 6.

[0034] The structure of the isolation component 2 is as follows Figure 3 , Figure 4 and Figure 5 As shown, the device includes a tube 21 and eight limiting rods 22 radially arranged on the outer circumference of the tube 21. The length of the tube 21 is greater than the width of the bearing ring 3. The inner diameter of the tube 21 and the outer diameter of the support rod 1 are correspondingly set to ensure that the tube 21 can be fitted onto the support rod 1. The tube 21 includes a first tube body 211 and a second tube body 212 arranged sequentially. The inner and outer diameters of the first tube body 211 and the second tube body 212 are the same. The second tube body 212 is used to hang the bearing ring 3, and the length of the second tube body 212 is greater than the length of the first tube body 211. The eight limiting rods 22 are arranged at the connection between the first tube body 211 and the second tube body 212, and the eight limiting rods 22 are evenly arranged in the circumferential direction. The length of the limiting rods 22 is such that when they are fitted onto the support rod 5 in a transverse state, the outer end of the limiting rod 22 abuts against the end face of the bearing ring 3 hung on the second tube body 212. Figure 7 As shown, the number of limiting rods 22 that contact the bearing race 3 has been increased to ensure the isolation effect of the isolator on the bearing race 3 and to ensure the stability of the bearing race 3 in the tilted hanging state, thereby improving its surface cleaning effect. To avoid collision and wear between the isolator 2 and the bearing race 3 during vibration, rubber sleeves 23 are fitted on the outside of the first tube body 211, the second tube body 212 and the limiting rods 22.

[0035] During the surface cleaning of the bearing race 3, before installing each bearing race 3, first install an isolator 2 onto the support rod 5, with the first tube portion 211 of the isolator 2 serving as the inlet end. Then, install one bearing race 3 sequentially, with the bearing race 3 fitting over the second tube portion 212, at which point the bearing race 3 is hooked onto the second tube portion 212. Next, install the second isolator 2, with the first tube portion 211 of the subsequently installed isolator 2 abutting against the second tube portion 212 of the previously installed isolator 2. Then, install the second bearing race 3, and so on. The bearing race 3 will then be in the following state after installation: Figure 6 As shown, after the bearing rings 3 are mounted on the support rod 5, an isolator 2 is fitted over the outermost bearing ring 3, and then a limiting plate 6 is inserted to prevent the bearing rings 3 from falling off the support rod 5 during vibration cleaning. After completing the above operations, the basket 1 is moved into the tank containing cleaning fluid, and the basket 1 is connected and fixed to the vibration element inside the tank. The vibration element drives the basket 1 to vibrate, colliding with the cleaning fluid inside the tank, thereby cleaning the surface of the bearing rings 3.

[0036] Preferably, the outermost isolation member 2 (the isolation member that isolates the outermost bearing ring 3 and the limiting plate 6) of the support rod 5 does not have a second tube body 212, but retains the first tube body 211 and the limiting rod 22 to save space inside the basket 1.

[0037] Limiting plate 6 structure as follows Figure 8 As shown, it includes an outer frame 61 and a mesh screen 62 disposed inside the outer frame 61, and a relief groove 63 corresponding to the support rod 5 is opened at the bottom end of the limiting plate 6.

[0038] The left and right side walls of the corresponding support rod 5 of basket 1 are respectively equipped with second vertical rods 102 corresponding to the limiting plates 6, such as Figure 1 , Figure 2 As shown, the second vertical rod 102 has a vertical groove on its inner side, and the left and right side frames of the limiting plate 6 are movably inserted into the two grooves, and the free end of the support rod 5 passes through the clearance groove 63.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
