Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning devices, in particular to a bearing ring cleaning device. Background Art

[0002] The main function of bearings is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Bearings can be divided into two categories: rolling bearings and sliding bearings according to the different friction properties of the moving elements. Rolling bearings generally consist of four parts: outer ring, inner ring, rolling element and cage.

[0003] The outer ring and inner ring of the rolling bearing are annular structures (hereinafter referred to as bearing rings), which are made by cutting long steel pipes. The surface of the bearing ring is not clean, and there are impurities such as oil, iron filings, and dust, which will affect the accuracy of subsequent finishing. Therefore, the surface of the bearing ring needs to be cleaned;

[0004] In the past, batches of bearing rings were placed in a material frame, and then the material frame was immersed in water for repeated cleaning. During this process, the bearing rings collided with each other and caused damage. In addition, impurities after cleaning would be deposited in the bearing ring at the lower end of the material frame, resulting in incomplete cleaning.

[0005] Therefore, we proposed a bearing ring cleaning device to solve the above problems. Utility Model Content

[0006] The utility model aims at the problem that in the prior art, a batch of bearing rings are placed in a material frame, and then the material frame is immersed in water for repeated cleaning. During this process, the bearing rings collide with each other and cause damage. In addition, impurities after cleaning will be deposited in the bearing ring at the lower end of the material frame, resulting in incomplete cleaning. The utility model proposes the following technical solutions:

[0007] The bearing ring cleaning device comprises a back plate, a rotating rod and an inner sleeve rod, wherein the inner sleeve rod is installed on the side wall of the back plate through an electrically driven rotating rod, and abutment plates for supporting the inner diameter of the inner wall of the bearing ring body are installed at equal intervals on the outer wall of the inner sleeve rod through an elastic mechanism;

[0008] The elastic mechanism includes a first limiting groove annularly opened on the outer wall of the inner sleeve rod, and a first spring is welded in the middle of the inner wall of the first limiting groove, the outer top end of the first spring is welded to the middle of the inner wall of the movable inner rod, and the outer top end of the movable inner rod is fixedly installed in the middle of the inner wall of the abutment plate.

[0009] The outer wall of the abutment plate can be adjusted according to the different inner diameters of the bearing ring body. At the same time, the bearing ring body can be limited from the inside of the bearing ring body, so as to avoid the bearing ring bodies colliding with each other and causing damage during the cleaning process. The bearing ring body to be cleaned is placed on the front side of the back plate under the support of the abutment plate to avoid impurities falling on the outer wall of the bearing ring body after cleaning, resulting in unclean cleaning.

[0010] As a preferred embodiment of the above technical solution, a first slider is fixedly installed on the outer side of the inner bottom end of the movable inner rod, and the first slider is slidably connected to the inner side of the first slide rail, and the first slide rail is symmetrically arranged on the inner side wall of the first limiting groove.

[0011] Under the sliding action of the first slider and the first slide rail, the movable inner rod can move smoothly inside the first limiting groove under the action of the elastic potential energy of the first spring, thereby ensuring the stability of the device during use.

[0012] As a preferred embodiment of the above technical solution, a protective pad is glued to the middle of the outer side wall of the abutment plate, and the outer side wall of the protective pad abuts against the inner side wall of the bearing ring body.

[0013] This prevents the outer wall of the abutment plate from directly abutting against the inner wall of the bearing ring body and causing scratches on the inner wall of the bearing ring body, thereby ensuring the service life of the bearing ring body.

[0014] As a preferred embodiment of the above technical solution, a second limiting groove is provided on the outer wall of the abutment plate close to the back plate side, and a second spring is welded on the inner side of the second limiting groove, the outer side of the second spring is welded to the middle part of the inner side wall of the installation frame, balls are rollingly embedded in the outer side walls of the installation frame, and the outer side of the balls rollingly abuts against the outer wall of the back plate, second sliders are fixedly installed on the upper and lower ends of the installation frame close to the second spring side, and the second sliders slide on the inner side of the second slide rail, and the second slide rail is symmetrically provided at the upper and lower ends of the inner wall of the second limiting groove.

[0015] Under the rolling action of the ball, the abutment plate can further move smoothly on the outer wall of the inner sleeve rod, and under the action of the elastic potential energy of the second spring, the smooth and efficient movement of the ball on the front outer wall of the back plate is guaranteed.

[0016] The beneficial effects of the utility model are:

[0017] The outer wall of the abutment plate can be adjusted according to the different inner diameters of the bearing ring body. At the same time, the bearing ring body can be limited from the inside of the bearing ring body, so as to avoid the bearing ring bodies colliding with each other and causing damage during the cleaning process. The bearing ring body to be cleaned is placed on the front side of the back plate under the support of the abutment plate to avoid impurities falling on the outer wall of the bearing ring body after cleaning, resulting in unclean cleaning.

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, in the embodiment of the utility model, it comprises a back plate 1, a rotating rod 2 and an inner sleeve rod 3. The inner sleeve rod 3 is installed on the side wall of the back plate 1 through the rotating rod 2 driven by electricity. The outer wall of the inner sleeve rod 3 is annularly and equidistantly installed with abutment plates 9 for supporting the inner diameter of the inner wall of the bearing ring body 11 through an elastic mechanism.

[0025] The elastic mechanism includes a first limiting groove 4 annularly opened on the outer wall of the inner sleeve rod 3, and a first spring 5 is welded to the middle of the inner wall of the first limiting groove 4, and the outer top end of the first spring 5 is welded to the middle of the inner wall of the movable inner rod 6, and the outer top end of the movable inner rod 6 is fixedly installed in the middle of the inner wall of the abutment plate 9.

[0026] With the cooperation of the elastic potential energy of the first spring 5, the movable inner rod 6 installed on the inner wall of the abutment plate 9 is driven to telescope inside the first limiting groove 4, so that the outer wall of the abutment plate 9 can be adjusted according to the different inner diameters of the bearing ring body 11. At the same time, the limiting work of the bearing ring body 11 can be completed from the inside of the bearing ring body 11, so that the bearing ring body 11 can be prevented from colliding with each other and causing damage during the cleaning process. The bearing ring body 11 to be cleaned is placed on the front side of the back plate 1 under the support of the abutment plate 9, so as to prevent impurities after cleaning from falling on the outer wall of the bearing ring body 11 and causing unclean cleaning.

[0027] like Figure 2 As shown, the first slider 7 is fixedly installed on the outer side of the inner bottom end of the movable inner rod 6, and the first slider 7 is slidably connected to the inner side of the first slide rail 8, and the first slide rail 8 is symmetrically arranged on the inner side wall of the first limiting groove 4.

[0028] Under the sliding action of the first slider 7 and the first slide rail 8, the movable inner rod 6 can move smoothly inside the first limiting groove 4 under the action of the elastic potential energy of the first spring 5, thereby ensuring the stability of the device during use.

[0029] like Figure 2 As shown, a protective pad 10 is glued to the middle of the outer side wall of the abutment plate 9 , and the outer side wall of the protective pad 10 abuts against the inner side wall of the bearing ring body 11 .

[0030] This prevents the outer wall of the abutment plate 9 from directly abutting against the inner wall of the bearing ring body 11 and causing scratches on the inner wall of the bearing ring body 11 , thereby ensuring the service life of the bearing ring body 11 .

[0031] like Figure 1 and Figure 3 A second limiting groove 12 is provided on the outer wall of the abutment plate 9 close to the back plate 1, and a second spring 13 is welded on the inner side of the second limiting groove 12. The outer side of the second spring 13 is welded to the middle part of the inner side wall of the mounting frame 14. Balls 15 are rollingly embedded in the outer side wall of the mounting frame 14, and the outer side of the ball 15 rolls and abuts against the outer wall of the back plate 1. Second sliders 16 are fixedly installed on the upper and lower ends of the mounting frame 14 close to the second spring 13, and the second sliders 16 slide on the inner side of the second slide rails 17. The second slide rails 17 are symmetrically arranged on the upper and lower ends of the inner wall of the second limiting groove 12.

[0032] Under the rolling action of the ball 15, the abutment plate 9 can further move smoothly on the outer wall of the inner sleeve rod 3. Under the action of the elastic potential energy of the second spring 13, the smooth and efficient movement of the ball 15 on the front outer wall of the back plate 1 is guaranteed.

[0033] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
