Description

Technical Field

[0001] This utility model specifically relates to a bearing ring cleaning device for bearing production and processing. Background Technology

[0002] Cleaning the bearing races is a crucial step in the bearing manufacturing process. Metal shavings, oil, and other impurities remaining on and inside the bearing races can severely affect the bearing's assembly accuracy and performance, thereby shortening its service life. Currently, most existing bearing ring cleaning devices use fixed spraying or immersion cleaning methods. When using fixed spraying, due to the fixed position of the bearing ring, there are blind spots in the cleaning process, making it difficult to thoroughly clean the inner and outer surfaces of the bearing ring, resulting in poor cleaning effect. Although immersion cleaning can clean the bearing ring to a certain extent, it takes a long time, is inefficient, and is difficult to remove stubborn oil stains and impurities. Utility Model Content

[0003] In view of the defects of the existing technology, the technical problem to be solved by this utility model is to provide a bearing ring cleaning device for bearing production and processing.

[0004] A bearing ring cleaning device for bearing production and processing includes a frame, on which a cleaning cylinder is rotatably mounted. A first motor for driving the cleaning cylinder to rotate is provided on the frame. The outer circumference of the cleaning cylinder has a plurality of recessed placement grooves evenly distributed, and the cleaning cylinder has a hollow inner cavity. A first water supply pipe is provided at the center of the cleaning cylinder within the inner cavity. A plurality of first spray pipes and a plurality of second spray pipes are evenly distributed and connected along the circumference of the first water supply pipe. The plurality of first spray pipes and the plurality of second spray pipes are evenly distributed at intervals along the length of the first water supply pipe, and the water outlets of the plurality of first spray pipes and the plurality of second spray pipes are respectively connected to the placement grooves. The water outlet of the first spray pipe is located at the bottom of the placement groove and faces the opening end of the placement groove, and the water outlet of the second spray pipe is located on the side wall of the placement groove and is inclined towards the opening end of the placement groove. The frame is provided with a collar that can be fitted onto the outside of the cleaning cylinder. The placement groove can rotate with the cleaning cylinder and forms a cleaning cavity between itself and the inner side of the collar.

[0005] In one embodiment, the collar is movably mounted on the frame and can reciprocate along the axial direction of the cleaning cylinder. The frame is provided with a driving component that can drive the collar to move. The collar includes a first connecting ring and a second connecting ring connected in a stepped manner. The axial length of the first connecting ring and the axial length of the second connecting ring are both greater than or equal to the length of the placement groove. The upper end of the first connecting ring is provided with a material placement port through its length direction.

[0006] In one embodiment, the lower end of the first connecting ring has a discharge port extending through it along its length. A cover plate that can be opened and closed is rotatably provided at the discharge port. A first flange is provided on one side of the cover plate, and a pin hole is provided through it on one side of the first flange. A second flange is provided on the first connecting ring on the side of the discharge port, and a spring pin that can cooperate with the pin hole is movably provided on one side of the second flange.

[0007] In one embodiment, a third connecting ring is rotatably disposed on the inner side of the second connecting ring along the same central axis. The inner side of the third connecting ring is provided with a rubber layer. The depth of the placement groove is less than the diameter of the bearing ring. The rubber layer can elastically abut against the periphery of the bearing ring located in the placement groove. Both ends of the rubber layer are provided with guide slopes.

[0008] In one embodiment, the driving component includes a second motor, a guide shaft, and a screw.

Furthermore, the rubber layer on the inner side of the collar can elastically abut against the circumference of the bearing ring. When the collar moves axially along the cleaning cylinder, the friction between the rubber layer and the bearing ring causes the bearing ring to rotate, enabling the first and second nozzles to clean the inner and outer circumferential surfaces of the bearing ring. This eliminates the need for repeated adjustments to the bearing ring position, reducing cleaning time and improving cleaning efficiency. At the same time, the cleaning cylinder rotates under the drive of the first motor, further enhancing the cleaning effect and efficiency. Attached Figure Description

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1 to 5 The present invention preferably provides a bearing ring cleaning device for bearing production and processing, including a frame 1. A cleaning cylinder 2 is rotatably mounted on the frame 1. A first motor 3 is provided on the frame 1 to drive the cleaning cylinder 2 to rotate. Several placement grooves 4 are evenly distributed along the circumference of the outer periphery of the cleaning cylinder 2, and the cleaning cylinder 2 has a hollow inner cavity. A first water supply pipe 5 is provided at the center of the cleaning cylinder 2 in the inner cavity. Several first spray pipes 6 and several second spray pipes 7 are evenly distributed along the circumference of the first water supply pipe 5. The several first spray pipes 6 and several second spray pipes 7 are evenly distributed at intervals along the length of the first water supply pipe 5, and the water outlets of the several first spray pipes 6 and several second spray pipes 7 are respectively connected to the placement grooves 4. The water outlet of the first spray pipe 6 is located at the bottom of the placement groove 4 and faces the opening end of the placement groove 4. The water outlet of the second spray pipe 7 is located on the side wall of the placement groove 4 and is inclined towards the opening end of the placement groove 4. A collar 8 is provided on the frame 1 that can be fitted onto the outside of the cleaning cylinder 2. The placement groove 4 can rotate with the cleaning cylinder 2 and forms a cleaning cavity with the inner side of the collar 8.

[0015] Specifically, by setting a placement groove on the cleaning cylinder, the bearing ring is placed in the placement groove, with the central axis of the bearing ring perpendicular to the axis of the cleaning cylinder. At this time, the water outlet end of the first spray pipe located at the bottom of the placement groove faces the outer circumferential side of the bearing ring, while the water outlet end of the second spray pipe located on the side wall of the placement groove faces the inner circumferential side of the bearing ring. Thus, the first and second spray pipes set in the placement groove respectively perform high-pressure spray cleaning on the inner and outer surfaces of the bearing ring, effectively removing impurities and oil stains from the inner and outer surfaces of the bearing ring, avoiding cleaning dead corners, and greatly improving the cleaning effect.

[0016] Furthermore, the collar 8 is movably mounted on the frame 1 and can reciprocate along the axial direction of the cleaning cylinder 2. The frame 1 is provided with a driving member 9 that can drive the collar 8 to move. The collar 8 includes a first connecting ring 81 and a second connecting ring 82 connected in a stepped manner. The axial length of the first connecting ring 81 and the axial length of the second connecting ring 82 are both greater than or equal to the length of the placement groove 4. The upper end of the first connecting ring 81 has a material placement port 83 extending through it along its length direction. Specifically, the collar is divided into a first connecting ring and a second connecting ring. When it is necessary to place or remove the bearing ring in the placement groove, the driving member drives the displacement to keep the first connecting ring in the connection state of being sleeved on the cleaning cylinder. When cleaning the bearing in the placement groove, the driving member drives the collar to move back to its original position, so that the first connecting ring and the second connecting ring are sequentially sleeved on the outside of the cleaning cylinder.

[0017] Furthermore, the lower end of the first connecting ring 81 is provided with a discharge port 84 extending along its length. A cover plate 85 that can be opened and closed is rotatably provided at the discharge port 84. A first flange 86 is provided on one side of the cover plate 85. A pin hole 87 is provided on one side of the first flange 86. A second flange 88 is provided on the first connecting ring 81 on the side of the discharge port 84. A spring pin 89 that can cooperate with the pin hole 87 is movably provided on one side of the second flange 88.

[0018] Specifically, the spring pin is a relatively mature existing technology, and its structural principle will not be described in detail here. It can be elastically extended and inserted into the pin hole. In the closed state, the spring pin remains in the connected state of being inserted into the pin hole. When it is necessary to open the cover plate, the user can press the spring pin to disengage it from the pin hole, thereby realizing the flipping and opening of the cover plate, so that the bearing ring in the slot can be unloaded through the discharge port.

[0019] Furthermore, a third connecting ring 90 is rotatably provided on the inner side of the second connecting ring 82 along the same central axis. The inner side of the third connecting ring 90 is provided with a rubber layer. The depth of the placement groove 4 is less than the diameter of the bearing ring. The rubber layer can elastically abut against the circumference of the bearing ring located in the placement groove 4. Both ends of the rubber layer are provided with guide slopes, so that it can abut against and press against the bearing ring as the collar moves.

[0020] Specifically, the rubber layer on the inner side of the third connecting ring can elastically abut against the circumference of the bearing ring. When the collar moves axially along the cleaning cylinder, the friction between the rubber layer and the bearing ring causes the bearing ring to rotate, allowing the first and second nozzles to clean the inner and outer circumferential surfaces of the bearing ring without having to adjust the bearing ring position multiple times, reducing cleaning time and improving cleaning efficiency. At the same time, when the cleaning cylinder rotates under the drive of the first motor, the third connecting ring can rotate relative to the second connecting ring to adapt to the rotation of the cleaning cylinder, further enhancing the cleaning effect and efficiency while avoiding lateral friction on the bearing ring.

[0021] Furthermore, the placement groove plays a preliminary positioning role for the bearing ring, and the rubber layer on the inner side of the collar can stably fix the bearing ring by elastically pressing against the circumference of the bearing ring, preventing the bearing ring from shaking or shifting during the cleaning process, ensuring the stability and reliability of the cleaning process, and also reducing the damage to the cleaning device caused by the shaking of the bearing ring.

[0022] Further, the driving component 9 includes a second motor 91, a guide shaft 92, and a screw 93. The guide shaft 92 and the screw 93 are axially arranged on the frame 1 with respect to the cleaning cylinder 2, and the screw 93 is rotatably connected to the frame 1 via bearings. The second motor 91 is mounted on the frame 1, and its drive shaft is connected to one end of the screw 93 to drive the screw 93 to rotate. The collar 8 is movably sleeved on the guide shaft 92 and the screw 93, and the collar 8 is threadedly connected to the screw 93. Specifically, the second motor drives the screw to rotate, thereby driving the collar to move axially along the guide shaft with the screw.

[0023] Furthermore, a water storage tank 11 is provided on the frame 1 below the cleaning cylinder 2, and a drainage gap is left between the cleaning cylinder 2 and the collar 8.

[0024] Furthermore, a discharge plate 12 is rotatably provided on one side of the water storage tank 11, and the discharge plate 12 can be rotated and tilted to be placed directly below the discharge port 84.

[0025] Furthermore, the frame 1 is provided with a second water supply pipe 13, which is connected to one end of the first water supply pipe 5 through a water pipe rotary joint.

[0026] In summary, when using this cleaning device, firstly, the bearing ring to be cleaned is placed in the placement groove through the material inlet. The first motor is started to rotate the cleaning cylinder, and simultaneously the second motor is started to drive the collar along the axial direction of the cleaning cylinder. As the collar moves, the rubber layer elastically presses against the circumference of the bearing ring in the placement groove, causing the bearing ring to rotate due to friction. At this time, water enters the first water supply pipe through the second water supply pipe and the water pipe rotary joint, and is then sprayed out from the first and second spray pipes respectively, performing high-pressure spray cleaning on the bearing ring. Wastewater generated during the cleaning process flows into the water storage tank through the drainage gap between the cleaning cylinder and the collar. After cleaning, the cover plate is opened, and the unloading plate is rotated to tilt it directly below the discharge port. The cleaned bearing ring falls onto the unloading plate under gravity, completing the unloading process.
