Description

Technical Field

[0001] The invention relates to the technical field of bearing production, and in particular to a bearing ring cleaning device used in bearing production and processing. Background Art

[0002] As a key component in mechanical equipment, the quality level of bearings directly affects the overall performance and life of the equipment. In the production and processing of bearings, when the bearings are finally assembled, it is necessary to clean the two rings of the bearings, namely the outer ring and the inner ring, especially the raceways of the bearing rings, because these raceways are the working surfaces of the bearings. If there is dust or slag on the working surface of the bearings, it will directly affect the assembly speed of the bearings, and affect the flexibility and service life of the assembled bearings.

[0003] At present, in production practice, the cleaning of bearing rings is mostly done by directly putting the bearings into the cleaning equipment and cleaning them with cleaning fluid. Since a large number of bearing rings are put in at one time, the bearing rings are scattered and piled up in the cleaning equipment, and it is difficult to fully clean them. In particular, there are usually some impurities and slag left on the raceways of the bearing rings. These pollutants are difficult to remove. Even with ultrasonic cleaning equipment, it is difficult to completely remove them because the bearing rings are close to each other, blocked, and the raceways of the bearing rings themselves are not easy to clean. As a result, impurities such as oil, dust, etc. are still attached to the raceways of the bearing rings.

[0004] Moreover, the commonly used ultrasonic cleaning equipment has a better cleaning effect on some lightweight small parts. For heavy and large parts such as bearing rings, they cannot be allowed to change positions in the cleaning liquid, so the cleaning effect is extremely limited, and it is easy to have residual dead corners, which basically require manual inspection and cleaning again. Therefore, in practice, there are also special stirring equipment for cleaning. The bearing rings are placed in the stirring equipment, and after adding detergent, they are stirred to clean them as much as possible. However, this traditional general method of cleaning parts is more difficult to clean the raceway of the bearing, and its effect is not better than that of an ultrasonic cleaner.

[0005] In addition, in the above cleaning equipment, it will be more difficult to clean the raceways of bearing rings, especially the bearing rings of cylindrical roller bearings, because the cross-section of the raceways of cylindrical roller bearing rings is rectangular, with dead angles at right angles, which are relatively more difficult to fully clean. The cross-section of the groove of the ball bearing is an arc, which is relatively easy to clean, but still has the above-mentioned shortcomings in cleaning effect. Summary of the invention

[0006] In view of this, the purpose of the present invention is to provide a bearing ring cleaning device for bearing production and processing, so as to solve the problem of insufficient thorough cleaning of bearing rings, especially bearing ring raceways in the prior art. It is very suitable for the production and manufacturing of some high-precision bearings, and can also be used as a further deep cleaning device after cleaning such as ultrasonic cleaning equipment.

[0007] The present invention is achieved through the following technical solutions:

[0008] A bearing ring cleaning device for bearing production and processing comprises a workbench for fixing an inner ring and an outer ring of a bearing, and the inner ring is installed in the outer ring; it also comprises a mounting arm and mounting blocks fixed at both ends of the mounting arm, the two ends of the mounting block are respectively elastically and telescopically mounted with telescopic columns along the radial direction of the bearing ring, and the two ends of the telescopic columns are respectively axially slidably mounted with sliding disks, the two sliding disks are connected together by an axially arranged tension spring, and in the assembled state, the two sliding disks completely fit the ports of their respective corresponding telescopic columns, and the surfaces of the raceways of the telescopic columns and the sliding disks facing the bearing rings are fixedly covered with cleaning covers; when compressed air is injected into the two mounting blocks through the hollow mounting arm, the two telescopic columns at each end are pushed to move radially and enter the raceways of the bearing rings, and the sliding disks at both ends of the telescopic columns move toward the side walls of the raceways of their respective corresponding bearing rings, so that all the cleaning covers squeeze and rub the inner walls of the raceways of their respective corresponding bearing rings.

[0009] Furthermore, the workbench includes a first conveying plate and a second conveying plate arranged in parallel and distributed up and down, and both sides of the two conveying plates are provided with guard plates, and the ends of the first conveying plate and the second conveying plate are respectively vertically fixed with a first baffle plate and a second baffle plate; wherein, the first conveying plate has a circular hole of a size for the inner ring of the bearing to fall vertically near the first baffle plate; the second baffle plate is embedded with a first electromagnet capable of fixing the outer ring of the bearing, and the second conveying plate is embedded with a second electromagnet for fixing the outer ring of the bearing near the second baffle plate, and when the outer ring of the bearing contacts the second baffle plate, the first electromagnet is energized to attract the outer ring of the bearing and then immediately de-energized, and the second electromagnet is energized to fix the outer ring of the bearing at a position on the first conveying plate opposite to the circular hole, so that after the inner ring of the bearing touches the first baffle plate, it freely falls into the outer ring of the bearing through the circular hole and remains fixed.

[0010] Furthermore, the two conveying plates each include a horizontal section and an inclined section, and the ends of the horizontal sections are used to vertically fix the baffle.

[0011] Furthermore, an air inlet cavity is provided in the mounting block, and an air inlet hole connected to the mounting arm is provided in the top center of the air inlet cavity, and a blade-shaped diverter plate is provided directly below the air inlet hole.

[0012] Furthermore, a drainage hole is provided in the horizontal column, and a conical plug is connected to the outlet end of the drainage hole through a conical spring, and a connecting rod is coaxially fixed to the small end of the conical plug. The connecting rod axially extends into the drainage hole and is fixedly connected to a piston slidably installed in the drainage hole. A circle of air holes is provided at the edge of the piston. In the assembled state, the conical plug is restricted by the conical spring to a position blocking the outlet end of the drainage hole. Before the compressed air pushes open the conical plug, the telescopic column has moved to a position where the column contacts the bottom of the rolling groove.

[0013] Furthermore, a sliding cylinder is coaxially fixed to the end of the sliding disk, the sliding cylinder is slidably fitted and inserted into the column, and is rotatably connected to a movable disk installed in the column through a round rod and a sliding seal.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0032] See also Figure 1-2The present invention provides a technical solution: a bearing ring cleaning device for bearing production and processing, mainly comprising a workbench for fixing and placing the inner ring 2 and the outer ring of the bearing, and the inner ring is installed in the outer ring, preferably coaxially installed. At the same time, this embodiment also includes a mounting arm 4 and mounting blocks 5 fixed at both ends of the mounting arm 4, the mounting arm 4 can rotate around the axis of the bearing ring, and a pair of telescopic columns 6 are installed in an elastic and telescopic manner at both ends of the mounting block 5 along the radial direction of the bearing ring, and the local components of the telescopic columns 6 can be arranged parallel to the axial direction of the bearing ring, and the two ends of the telescopic columns 6 in the vertical direction need to be axially slidably installed with sliding disks 14, and the sliding disks 14 are preferably circular plate-shaped structures. The two sliding disks 14 are connected together by an axially arranged tension spring (the number is not shown in the figure), and the function of the tension spring is that when the device is in an assembled state, the two sliding disks 14 completely fit the ports of the corresponding telescopic columns 6, that is, the corresponding ports are closed. Specifically, at least the surfaces of the telescopic column 6 and the sliding plate 14 facing the inner wall of the raceway of the bearing ring should be fixedly covered with a cleaning cover 15. The raceway is a groove for installing the roller, and the cleaning cover 15 mentioned above is mainly in friction contact with the inner wall of the raceway of the bearing ring, and then the raceway is assembled when the mounting arm 4 rotates. In actual use, compressed air is injected into the two mounting blocks 5 through the hollow mounting arm 4. The influx of compressed air can quickly push the two telescopic columns 6 at each end to move along the radial direction of the bearing ring, so that the telescopic columns 6 enter the raceway, and at this time, the compressed air is continuously injected, and the sliding plates 14 at both ends of the telescopic column 6 move toward the side walls of the corresponding raceways, so that all the cleaning covers 15 in the cleaning device can fully squeeze and rub the inner walls of the corresponding raceways, and then the bearing ring can be cleaned, so that when the roller of the bearing is installed later, it can be installed better, avoiding the presence of stains, slag inclusions, etc. in the raceway, which is conducive to improving the bearing assembly efficiency and ensuring the assembly quality.

[0033] In this embodiment: For the above arrangement of the two bearing rings, in this embodiment, specifically, Figure 3As shown, the workbench includes a first conveying plate 7 and a second conveying plate 8 arranged in parallel and distributed up and down. Both sides of the two conveying plates are provided with guard plates. The interval between the two guard plates is preferably equal to the outer diameter of the bearing rings to be conveyed, so as to better convey the bearing rings. In addition, at the ends of the first conveying plate 7 and the second conveying plate 8 in this embodiment, a first baffle plate 9 and a second baffle plate 10 are specially fixed vertically, respectively, to assemble the bearing rings that slide down and achieve the function of stopping. During the manufacturing process, a circular hole of a size for the bearing inner ring 2 to fall vertically is provided at the first conveying plate 7 near the first baffle plate 9. In addition, the second baffle plate 10 is embedded with a first electromagnet 11 capable of fixing the outer ring 1 of the bearing, and the second conveying plate 8 is embedded with a second electromagnet 12 for fixing the outer ring 1 of the bearing near the second baffle plate 10. The reason why there are two electromagnets to fix the outer ring 1 of the bearing is that when the outer ring 1 of the bearing contacts the second baffle plate 10, the first electromagnet 11 is immediately energized, and when it blocks and collides with the outer ring 1 of the bearing, it simultaneously sucks the outer ring 1 of the bearing, and then immediately cuts off the power to achieve timely stop. Subsequently, the second electromagnet 12 is energized to fix the outer ring 1 of the bearing on the first conveying plate 7 in a downward suction manner, so as to well achieve the control of the position of the outer ring 1 of the bearing facing the circular hole, and at the same time, it is convenient for the inner ring 2 of the bearing to freely fall into the outer ring 1 of the bearing through the circular hole after touching the first baffle plate 9, and also be attracted by the second electromagnet 12 and remain fixed, thereby achieving the pre-position placement of the two bearing rings, especially achieving the best coaxial position placement. As for the conveying plate, it can be as follows Figure 3 As shown, both conveying plates include a horizontal section 3 and an inclined section, and the end of the horizontal section 3 is used to vertically fix the baffle, and also serves as a carrier for placing the inner ring and the outer ring, which is essentially a realization form of the aforementioned workbench.

[0034] In this embodiment: Figure 4 As shown, there is an air inlet cavity in the mounting block 5, which can be a rectangular cavity, and an air inlet hole connected to the mounting arm 4 is provided at the top center of the air inlet cavity, and a blade-shaped diverter plate 16 is provided just below the air inlet hole to achieve timely diversion of compressed air, and T-shaped telescopic columns 6 are slidably installed on both sides of the diverter plate 16, specifically, the cross column 601 in the middle of the telescopic column 6 is inserted into the mounting block 5 in a sliding and sealing manner, and is elastically connected to the end of the mounting block 5 through a reset spring 17. When the compressed air pushes the horizontal column 601 to translate, the reset spring 17 is stretched, and the telescopic column 6 moves as a whole toward the raceway of the bearing ring. Moreover, in this process, a sleeve 18 can be coaxially provided on the outside of the reset spring 17. One end of the sleeve 18 is slidably inserted into the mounting block 5, and the other end is fixedly connected to the vertically arranged column 602 of the telescopic column 6 as a whole. The sleeve 18 never slides away from the mounting block 5, thereby protecting the reset spring 17 and preventing dust from falling on the components in the sleeve 18.

[0035] In this embodiment, as a very useful structural design, continue to refer to Figure 4-Figure 5 , a person skilled in the art can coaxially set a drainage hole 13 in the horizontal column 601, and the outlet end of the drainage hole 13 is connected to a cone plug 19 through a cone spring 20. The cone plug 19 is a conical plug. A connecting rod 21 is coaxially fixed to the small end of the cone plug 19. The connecting rod 21 axially extends into the drainage hole 13 and is fixed to a piston 22 slidably installed in the drainage hole 13. The piston 22 plays a role in guiding the movement of the cone plug 19. In addition, a circle of air holes 23 is provided near the edge of the piston 22, so that the compressed air can flow into the small end face of the cone plug 19 through the air holes 23, and then push the cone plug 19 to open the cone plug 19, that is: in the assembled state of the cleaning device In this state, the cone plug 19 is restricted by the cone spring 20 to the position of the outlet end of the drainage hole 13, and before the compressed air pushes open the cone plug 19, the compressed air does not flow into the column 602 of the telescopic column 6 due to the resistance of the cone spring 20. Therefore, at this time, the telescopic column 6 can have been translated to the position where the column 602 contacts the bottom of the raceway groove. Subsequently, compressed air continues to be input. When the pressure increases, the cone plug 19 is pushed open, allowing the compressed air to enter the column 602, and then the two sliding plates 14 are pushed to move away from each other, and then they are in contact with the upper and lower side walls of the raceway, so as to achieve the cleaning of the groove bottom surface and the upper and lower groove side walls of the bearing raceway.

[0036] In this embodiment, more specifically, Figure 2 and Figure 4 , a slide cylinder 26 is coaxially fixed to the end of the sliding disk 14, and this slide cylinder 26 is inserted into the column 602 in a sliding fit, and is rotatably connected through a round rod 25 and a movable disk (not shown in the figure) installed in the column 602 through a sliding seal. The two movable disks facing each other are connected by a tension spring, and this tension spring can make the cone plug 19 always be on one side between the two movable disks, so that after the cone plug 19 is pushed open, the compressed air can promptly push the two movable disks to move, and then move the sliding disk 14. In order to more accurately control the above position relationship, it can be as follows Figure 4 A retaining ring (not shown in the figure) coaxial with the cone plug 19 is also provided outside the cone plug 19. When the device is in the assembled state, the tension spring makes the two movable disks contact and connect with the upper and lower sides of the retaining ring.

[0037] In the above embodiment, after the sliding plate 14 slides away from the end of the column 602 of the telescopic column 6, a circle of annular grooves will be formed. The groove bottom area of ​​the raceway of the bearing ring corresponding to the groove cannot be cleaned. Therefore, in order to fully clean without dead angles, the side wall of the slide cylinder 26 facing the raceway groove bottom is provided. Figure 6-Figure 7, a number of air outlets are specially opened, and in the area where the air outlets are set, an elastic rubber 24 with a cleaning layer fixed thereon is covered. Of course, a cleaning structure for cleaning the raceway of the bearing ring also needs to be adaptively installed on the elastic rubber 24. In practice, if Figure 6 One end of the elastic rubber 24 is fixed to the bottom edge of the sliding plate 14, and the other end is fixed to the side wall of the slide cylinder 26. The movable plate has a through hole (not shown in the figure) so that when the compressed air pushes the sliding plate 14 to slide out of the column 602, Figure 7 As shown in FIG. 1 , the elastic rubber 24 expands outward to fill the annular groove area formed between the sliding plate 14 and the column 602. Then, when the telescopic column 6 rotates along the raceway of the bearing ring, all inner walls of the mounting groove can be completely cleaned. In order to make it easier for the elastic rubber 24 to fill the annular groove, as shown in FIG. Figure 6 The part where the elastic rubber 24 is connected to the outer wall of the column 602 and the part where the elastic rubber 24 is connected to the sliding plate 14 are both provided with recessed grooves, and the elastic rubber 24 is more easily bent at the grooves and expanded into the above-mentioned annular grooves.

[0038] In this embodiment, in order to solve the problem that the above-mentioned annular groove may cause cleaning omissions, in addition to the above-mentioned structural design scheme, it is also possible to Figure 8 As shown, a curved arm 27 is fixed on the side of the sliding plate 14, and a mounting frame 28 is fixed at the end of the curved arm 27. Rollers 29 are installed on the mounting frame 28. These rollers 29 are axially parallel to the column 602, and the length of the rollers 29 needs to be sufficient to always be located on one side of the annular groove formed between the sliding plate 14 and the column 602 during the process of the sliding plate 14 sliding out of the column 602. Then, as a supplementary cleaning element, it adaptively cooperates with the telescopic position of the sliding plate 14 to cover the missed area, which is very clever.

In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
