Description

Technical Field

[0001] This utility model relates to the field of bearing manufacturing technology, and in particular to a bearing outer surface cleaning device for bearing manufacturing. Background Technology

[0002] In the bearing manufacturing process, the cleanliness of the bearing's outer surface has a crucial impact on its performance and service life. If oil, debris, or other impurities remain on the outer surface, it will not only affect the bearing's rotational accuracy but may also accelerate wear and reduce its lifespan. With the continuous development of the manufacturing industry, the quality requirements for bearings are increasing, making efficient and precise bearing outer surface cleaning technology a focus of industry attention.

[0003] For example, a Chinese patent for a bearing cleaning device, patent publication number CN221848005U, describes a method that uses a cleaning tank and spray device to clean bearings to a certain extent. However, this patent only addresses the basic cleaning problem and does not consider the crucial issue of maintaining order during the bearing feeding process. In actual production, disordered feeding may cause multiple sets of bearings to simultaneously enter the cleaning area, resulting in congestion and affecting the cleaning effect.

[0004] Therefore, we propose a bearing outer surface cleaning device for bearing production to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a bearing outer surface cleaning device for bearing production, which solves the problem in the prior art that the bearing cleaning device is difficult to adjust the bearing feeding interval, resulting in the disorderly influx of bearings into the cleaning area and causing congestion, which in turn affects the allocation of cleaning space and the cleaning effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A bearing outer surface cleaning device for bearing production includes a cleaning tank, an inlet on one side of the cleaning tank, and the inlet is inclined; and also includes: A conveyor belt is installed on the side of the cleaning tank near the inlet, and a conveyor belt bracket is fixedly installed at the bottom of the conveyor belt. A feeding structure is installed on the side of the conveyor belt support near the cleaning box; The cleaning tank is filled with cleaning fluid, and the fluid level is below the inlet.

[0007] Preferably, a rotating screen is rotatably installed at the bottom of the cleaning tank, and the rotating screen is driven by a motor.

[0008] Preferably, a spray pipe is fixedly installed inside the cleaning tank on the side above the inlet, and multiple sets of spray nozzles arranged in a ring are installed at the bottom of the spray pipe.

[0009] Preferably, the feeding structure includes a drive box and a rotating stop bar, and an inclined bar is fixedly installed on the side of the conveyor belt support near the cleaning box, and the drive box is fixedly installed on the inclined bar; A rotating stop bar is rotatably mounted on the top of the drive box, and the rotating stop bar is higher than the surface of the conveyor belt.

[0010] Preferably, a baffle plate is fixedly installed on the top of the conveyor belt support on the side opposite to the rotating stop bar.

[0011] Preferably, a grooved wheel is rotatably mounted inside the drive box on the side near the rotating stop, and the middle part of the grooved wheel is fixedly connected to the rotating stop via a rotating rod; Each of the four sides of the grooved wheel has a set of arc-shaped grooves, and a set of straight grooves is formed between each set of arc-shaped grooves. The number of multiple sets of arc-shaped grooves is the same as the number of multiple sets of straight grooves.

[0012] Preferably, a drive motor is fixedly installed inside the drive box on the side near the groove wheel, and a rotating disk is fixedly installed on the output shaft of the drive motor; An arc-shaped plate is fixedly installed on one side of the top of the rotating disk, and a round pin is fixedly installed on the side of the top of the rotating disk opposite to the arc-shaped plate. The bow-shaped plate engages with the arc-shaped groove in the grooved wheel; and the round pin engages with the straight groove in the grooved wheel.

[0013] This utility model has at least the following beneficial effects: The device adjusts the bearing feeding interval through an intermittent transmission mechanism between a grooved wheel and a rotating disk inside the drive box. When the drive motor rotates the rotating disk, the circular pin on the rotating disk engages with the linear slot of the grooved wheel, causing the wheel to rotate. The arc-shaped plate fits into the arc-shaped groove of the grooved wheel, ensuring the smoothness of the wheel's rotation and the positioning effect during intermittent rotation. Furthermore, the intermittent rotation of the rotating stop is controlled by the fixed connection between the grooved wheel and the rotating stop. When the rotating stop rotates upward, it releases a single or a fixed quantity of bearings; when it rotates downward, it blocks subsequent bearings. This effectively avoids space congestion caused by multiple sets of bearings entering the cleaning box simultaneously, ensuring that bearings enter the cleaning area one by one or in a reasonable number, providing each bearing with sufficient cleaning space and guaranteeing the orderly conduct of the cleaning process from the source.

[0014] This utility model also has the following beneficial effects: The baffle plate at the top of the conveyor belt support, facing away from the rotating stop bar, works synergistically with the material feeding interval adjustment structure. During the conveyor belt's conveying of the bearings, the baffle plate prevents the edge bearings from falling due to conveyor belt inertia, equipment vibration, or conveying angle deviation, thus avoiding damage or loss of the bearings. Simultaneously, combined with the orderly material feeding rhythm, it prevents the connection between material feeding and cleaning from being disrupted by falling bearings, ensuring the continuous operation of the entire cleaning device and reducing production losses caused by material loss or process interruptions.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] Reference Figure 1-5 A bearing outer surface cleaning device for bearing production includes a cleaning tank 1, an inlet 2 on one side of the cleaning tank 1, and the inlet 2 is inclined; and also includes: A conveyor belt 3 is provided on the side of the cleaning tank 1 near the inlet 2, and a conveyor belt bracket 4 is fixedly installed at the bottom end of the conveyor belt 3. A feeding structure is installed on the side of the conveyor belt support 4 near the cleaning box 1; The cleaning tank 1 is filled with cleaning fluid, and the level of the cleaning fluid is lower than that of the inlet 2.

[0020] Furthermore, a rotating mesh 7 is rotatably installed at the bottom of the cleaning tank 1. The rotating mesh 7 is driven by a motor, which drives the rotating mesh 7 to rotate at the bottom of the cleaning tank 1. When the bearing enters the cleaning tank 1 and falls onto the rotating mesh 7, the rotating mesh 7 can drive the bearing to make a circular motion in the cleaning fluid. This motion mode can ensure that all parts of the bearing's outer surface can fully contact the cleaning fluid, avoiding incomplete cleaning of some parts of the bearing due to prolonged stillness. This improves the uniformity and efficiency of cleaning the bearing's outer surface. At the same time, the mesh structure of the rotating mesh 7 can also allow impurities generated during the cleaning process to fall smoothly to the bottom of the cleaning tank 1, reducing the possibility of secondary contamination of the bearing by impurities.

[0021] Furthermore, a spray pipe 8 is fixedly installed inside the cleaning tank 1 on the side higher than the inlet 2, and multiple sets of nozzles arranged in a ring are installed at the bottom of the spray pipe 8. The spray pipe 8 is set inside the cleaning tank 1 at a position higher than the inlet 2, and equipped with multiple sets of nozzles arranged in a ring. When the bearing enters the cleaning tank 1 through the inlet 2 or moves to the spray area during the cleaning process, the multiple sets of nozzles arranged in a ring can spray the outer surface of the bearing with high pressure from different angles. This can pre-clean the large amount of oil and debris initially attached to the outer surface of the bearing, reducing the burden of subsequent soaking and cleaning with cleaning solution.

[0022] Furthermore, the feeding structure includes a drive box 5 and a rotating stop bar 6. An inclined bar is fixedly installed on the side of the conveyor belt support 4 near the cleaning box 1, and the drive box 5 is fixedly installed on the inclined bar. A rotating stop bar 6 is rotatably mounted on the top of the drive box 5, and the rotating stop bar 6 is higher than the surface of the conveyor belt 3. The drive box 5 is fixed to the side of the conveyor belt bracket 4 near the cleaning box 1 by an inclined rod. The rotating stop bar 6 at the top of the drive box 5 is higher than the surface of the conveyor belt 3. This feeding structure can play a role in the orderly feeding of the bearings conveyed on the conveyor belt 3. When the bearings move towards the cleaning box 1 with the conveyor belt 3, the rotating stop bar 6 can prevent the bearings from continuously and disorderly entering the cleaning box 1. The rotation of the rotating stop bar 6 realizes the interval release of the bearings, avoiding multiple groups of bearings rushing into the cleaning box 1 at the same time and causing congestion. It ensures that the bearings can enter the cleaning box 1 one by one or in a reasonable number for cleaning. This not only ensures the orderly development of the cleaning work inside the cleaning box 1, but also allows each bearing to have sufficient cleaning space, thus improving the cleaning effect.

[0023] Furthermore, a baffle plate 9 is fixedly installed on the top side of the conveyor belt support 4 opposite to the rotating stop bar 6. When the bearing is conveyed on the conveyor belt 3, the baffle plate 9 can block and limit the bearing at the edge of the conveyor belt 3. This effectively prevents the bearing from falling off the side of the conveyor belt 3 opposite to the rotating stop bar 6 due to the inertia, vibration, or conveying angle of the conveyor belt during transport, ensuring the integrity of the bearing during transport, reducing damage or loss caused by falling bearings, and also avoiding disruption to the normal operation of the entire cleaning device due to falling bearings, thus improving the stability and reliability of the device operation.

[0024] Furthermore, a grooved wheel 11 is rotatably mounted inside the drive box 5 on the side near the rotating stop 6, and the middle part of the grooved wheel 11 is fixedly connected to the rotating stop 6 through a rotating rod. A set of arc-shaped grooves is provided around the perimeter of the groove wheel 11, and a set of straight grooves is provided between the multiple sets of arc-shaped grooves. The number of multiple sets of arc-shaped grooves is the same as the number of multiple sets of straight grooves. The grooved wheel 11 is fixedly connected to the rotating stop 6 through a rotating rod. The number of arc-shaped grooves and straight grooves opened around its perimeter is the same. This structure provides a stable and regular rotation drive basis for the rotating stop 6.

[0025] Furthermore, a drive motor 10 is fixedly installed inside the drive box 5 on the side near the grooved wheel 11, and a rotating disk 12 is fixedly installed on the output shaft of the drive motor 10. An arc-shaped plate 13 is fixedly installed on one side of the top of the rotating disk 12, and a round pin 14 is fixedly installed on the side of the top of the rotating disk 12 away from the arc-shaped plate 13. The bow-shaped plate 13 engages with the arc-shaped groove in the grooved wheel 11; and the round pin 14 engages with the straight groove in the grooved wheel 11. The drive motor 10 drives the rotating disk 12 to rotate. The bow-shaped plate 13 on the rotating disk 12 engages with the arc-shaped groove of the grooved wheel 11, and the round pin 14 engages with the straight groove of the grooved wheel 11, forming a stable and reliable intermittent transmission mechanism. When the rotating disk 12 rotates, the round pin 14 enters the straight groove of the grooved wheel 11, driving the grooved wheel 11 to rotate. At this time, the bow-shaped plate 13 is in contact with the arc-shaped groove of the grooved wheel 11, ensuring the smooth rotation of the grooved wheel 11. When the round pin 14 disengages from the straight groove, the bow-shaped plate 13 is still in contact with the arc-shaped groove, which plays a positioning role for the grooved wheel 11 and prevents the grooved wheel 11 from continuing to rotate due to inertia. This transmission method can precisely control the rotation angle and intermittent time of the grooved wheel 11, thereby controlling the rotation rhythm of the rotating stop 6, adjusting the bearing feeding interval, ensuring that the bearings enter the cleaning box 1 in an orderly and uniform manner, and guaranteeing the operation of the entire cleaning device.

[0026] In summary: First, the drive mechanism of conveyor belt 3 is started. Supported by conveyor belt bracket 4, conveyor belt 3 begins to rotate at a constant speed. The operator places the bearing to be cleaned on the surface of conveyor belt 3, and conveyor belt 3 drives the bearing to move towards cleaning box 1. During this process, because a baffle plate 9 is fixed on the side of the top of conveyor belt bracket 4 away from the rotating stop bar 6, when the bearing moves to the edge with conveyor belt 3, the baffle plate 9 will block and limit the bearing, effectively preventing the bearing from falling off the side of conveyor belt 3 due to the inertia of the conveyor belt, equipment vibration or conveying angle deviation, laying the foundation for subsequent orderly feeding and cleaning. Simultaneously, the drive motor 10 inside drive box 5 is started, and the output shaft of drive motor 10 drives the rotating disk 12 to rotate at a constant speed. Since an arc-shaped plate 13 is fixed to one side of the top of the rotating disk 12 and a round pin 14 is fixed to the other side, and the arc-shaped plate 13 meshes with the arc-shaped groove of the grooved wheel 11 and the round pin 14 meshes with the straight groove of the grooved wheel 11, when the rotating disk 12 rotates, it will drive the arc-shaped plate 13 and the round pin 14 to make synchronous circular motion. When the round pin 14 rotates with the rotating disk 12 and enters the straight groove of the grooved wheel 11, the round pin 14 will drive the grooved wheel 11 to rotate around its own axis. At the same time, the arc-shaped plate 13 and the arc-shaped groove of the grooved wheel 11 are tightly fitted to ensure that the grooved wheel 11 rotates smoothly without jamming. When the round pin 14 rotates with the rotating disk 12 and disengages from the straight groove of the grooved wheel 11, the arc-shaped plate 13 still maintains meshing with the arc-shaped groove of the grooved wheel 11. The rotating rods 11 and 6 act as positioning rods to prevent them from rotating due to inertia. Since the middle of the rotating rod 11 is fixedly connected to the rotating stop rod 6, the intermittent rotation of the rotating rod 11 will drive the rotating stop rod 6 to rotate intermittently in sync. When the rotating stop rod 6 rotates upward, it will release a single bearing on the conveyor belt 3; when the rotating stop rod 6 rotates downward, it will block the subsequent bearing from moving forward. This will ultimately achieve the effect of bearings entering the cleaning box 1 in an orderly manner at intervals, avoiding congestion caused by multiple sets of bearings entering at the same time, and ensuring efficient use of the internal space of the cleaning box 1. After the bearing is released by the rotating stop rod 6, it slides down the end of the conveyor belt 3 to the inclined inlet 2, and then enters the cleaning box 1 through the inlet 2. During this process, because a spray pipe 8 is fixed inside the cleaning tank 1 on the side higher than the inlet 2, and multiple sets of nozzles are installed at the bottom of the spray pipe 8 in a ring, the water supply and pressurization system of the spray pipe 8 is started in advance. The high-pressure cleaning fluid will form a multi-angle spray flow through the multiple sets of ring nozzles. The multiple sets of nozzles will spray the outer surface of the bearing with high pressure in all directions, quickly washing away a large amount of oil, metal debris and other impurities initially attached to the bearing surface, reducing the cleaning pressure for subsequent soaking and cleaning. The bearing that enters the cleaning tank 1 will fall naturally onto the rotating net 7. At this time, the drive motor of the rotating net 7 is started, and the motor drives the rotating net 7 to rotate at a constant speed in the cleaning fluid.When the rotating mesh 7 rotates, it drives the bearings on it to make synchronous circular motion, so that every part of the outer surface of the bearing can fully contact the cleaning fluid in the cleaning tank 1. This avoids incomplete cleaning caused by prolonged local static state of the bearing. At the same time, the mesh structure of the rotating mesh 7 allows small impurities and debris that fall off the bearing surface during the cleaning process to pass through the mesh smoothly and fall to the bottom of the cleaning tank 1, effectively separating them from the bearing and preventing secondary contamination of the bearing by impurities.
