Description

Technical Field

[0001] The invention relates to the technical field of bearing processing equipment, in particular to a rust removal device for a groove in a bearing ring. Background Art

[0002] During the production and use of bearings, bearing rings are key components, and their surface condition has a crucial impact on bearing performance and life. Because bearing rings are mostly made of metal, they are susceptible to oxidation and rust during processing, storage, and use. Rust not only damages the rings' surface precision, increasing surface roughness and affecting the bearing's rotational smoothness and operating accuracy, but can also cause ring dimensional changes, affecting the fit accuracy with other components and reducing the reliability of the entire bearing system.

[0003] like Figure 1 As shown, when the inner groove of the bearing ring is derusted, the traditional manual derusting method, such as manual grinding with sandpaper, wire brushes and other tools, can remove rust to a certain extent, but the efficiency is extremely low. Some automated derusting equipment, such as some equipment that adopts the principle of mechanical grinding, is often difficult to adapt to bearing rings of different specifications. It is impossible to achieve comprehensive and effective rust removal for the inner groove of the ring. There is an urgent need for a device that can derust the inner groove of the bearing ring.

[0004] Patent publication number CN205966620U proposes a bearing ring cleaning and rust-proofing device. This equipment utilizes a conveyor line to connect a cleaning tank, a rinsing tank, an anti-rust spray unit, and an anti-rust spray unit in series. The cleaning time and rhythm are adjusted by controlling the conveyor line speed to clean and rust-proof the bearing rings. This device primarily cleans and rust-proofs the entire bearing ring using liquid, making it difficult to effectively remove rust from the grooves within the bearing rings.

[0005] Patent publication number CN221416191U proposes a rust removal device for inner rings used in automotive bearing production. A first motor drives a threaded rod to rotate, causing a slider to move along the rod, thereby driving a second motor and a brush to clean and remove rust from the bearing inner ring. However, this device primarily targets the cleaning of bearing inner rings and may not be effective for rust removal within grooves of bearing rings of varying specifications, resulting in limited rust removal effectiveness and efficiency.

[0006] Patent publication number CN210023983U proposes a device for removing rust from the inner groove of a friction wheel. This device utilizes a fixed frame, a solenoid sleeve, an adjustment push rod, a feed screw, and a scraper assembly. Rotating the adjustment handle drives the feed screw, while pushing the adjustment push rod moves the scraper assembly closer to or further from the inner groove of the friction wheel to scrape away rust. However, the scraper assembly used for rust removal can easily damage the workpiece surface, and the adjustment process is relatively complex. Summary of the Invention

[0007] The object of the present invention is to provide a device for removing rust from the inner groove of a bearing ring, so as to solve the problem in the prior art that the inner groove of a bearing ring cannot be fully and effectively removed from the rust.

[0008] The technical problem solved by the present invention is achieved by adopting the following technical solutions: A bearing ring inner groove rust removal device includes an outer cover housing and further includes: A push-type machine tool unit, comprising a base plate and a push-type slide portion mounted on the base plate, a drive motor mounted on the push-type slide portion, and a brush head mounted on the rotating shaft end of the drive motor; A bearing ring fixing unit includes a lifting platform installed on the base plate and a rotatable magnetic turntable installed on the lifting platform. A driving unit for driving the rotation of the magnetic turntable is installed on the back of the lifting platform. The bearing ring is magnetically fixed at the center of the magnetic turntable.

[0009] The magnetic turntable comprises a casing and an electromagnet installed in the casing, and an adsorption platform is detachably installed at the opening of the casing.

[0010] The housing includes a shell cylinder and a box frame arranged on the back of the shell cylinder. A shaft column is installed at the center of the back of the shell cylinder. A power supply for powering the electromagnet is installed on the upper end of the box frame, and a counterweight balancing block is installed on the lower end of the box frame.

[0011] A miniature camera is installed at the center of the adsorption platen, which is used to observe the contact between the brush head and the groove in the bearing ring. The adsorption platen is used to adsorb a diameter scale ring on the end face of the bearing ring, and adsorbs a support block for positioning the bearing ring.

[0012] The driving part includes a supporting shaft frame for connecting with the shaft column and a supporting seat plate fixedly arranged on the lifting platform, and a transmission member is installed on the supporting seat plate.

[0013] The supporting shaft frame includes a frame rod detachably connected and installed on the back of the lifting platform and a connecting shaft axially connected to the middle of the frame rod, and one end of the connecting shaft is connected to the shaft column.

[0014] The transmission member includes a servo motor fixedly mounted on the support plate and a first transmission wheel connected to the output end of the servo motor. A second transmission wheel is mounted on the other end of the connecting shaft, and a transmission belt is provided between the first transmission wheel and the second transmission wheel.

[0015] The lifting platform includes a plate body and positioning guide pillars connected to both sides of the plate body, the lower end of the plate body is connected to a first pneumatic cylinder, and the telescopic end of the first pneumatic cylinder is connected to the lower end of the plate body; A circular opening for installing the magnetic turntable is provided in the middle of the plate; The positioning guide column comprises sleeve blocks connected and mounted on both sides of the plate body and guide column rods inserted into the sleeve blocks.

[0016] The propulsion slide portion includes a guide rail installed on the base plate and a movable slide installed on the guide rail. A second pneumatic cylinder is installed on the base plate, and the telescopic end of the second pneumatic cylinder is connected and installed on the slide.

[0017] The brush head comprises a mounting end for connecting to the rotating shaft end of the driving motor and a circular brush head connected to the mounting end.

[0018] The design idea of the present invention is: Due to the unique location and shape of the grooves within bearing rings, traditional rust removal methods (such as manual polishing or simple mechanical grinding) are difficult to fully cover, resulting in low rust removal efficiency and unsatisfactory results. The present invention achieves efficient rust removal through direct contact and friction between the brush head and the inner grooves. The brush head is mounted on a movable push-slide, enabling precise entry into the inner grooves and ensuring comprehensive and effective rust removal.

[0019] To achieve comprehensive rust removal within the inner groove, the present invention utilizes a dual-motion synergy of "rotation + propulsion." Driven by the propulsion slide, the brush head is fed into the inner groove. Simultaneously, the rotation of the magnetic turntable enables full omnidirectional rotation of the bearing ring, ensuring full contact between the brush head and all parts of the inner groove, thus achieving comprehensive rust removal. The extension and retraction of the second pneumatic cylinder drives the slide along the guide rail, moving the brush head in and out of the inner groove. The drive unit (consisting of a servo motor and transmission components) drives the magnetic turntable, enabling full omnidirectional rotation of the bearing ring during rust removal.

[0020] Considering the diverse specifications of bearing rings, this invention incorporates an adjustable fixing and rust removal mechanism to accommodate bearing rings of varying diameters. A diameter scale ring is provided on the adsorption platen. By aligning the outer ring of the bearing ring with the scale ring, the center of the bearing ring is aligned with the center of the adsorption platen, achieving precise positioning. A support block supports the lower end of the bearing ring, further enhancing positioning stability and accuracy.

[0021] The first and second pneumatic cylinders control the movement of the lifting platform and the propulsion slide, respectively, achieving automated up and down movement and forward and backward propulsion. A servo motor is used as the drive unit's power source, and precise rotation control is achieved through a drive belt and drive pulleys (first and second drive pulleys), ensuring stable rotation of the magnetic turntable. A miniature camera is installed at the center of the adsorption platform to monitor the contact between the brush head and the groove in the bearing ring in real time, allowing the operator to adjust rust removal parameters promptly to ensure effective removal.

[0022] The advantages and beneficial effects of the present invention are: 1. While ensuring functionality, the present invention optimizes the overall structure of the device, improving its stability and reliability while reducing manufacturing and maintenance costs. The rust removal device is divided into two modules: a push-type machine tool unit and a bearing ring fixing unit. Each module has a compact internal structure, making it easy to assemble and maintain.

[0023] 2. The present invention rotatably mounts the magnetic turntable on the lifting platform, and a driving part for driving the rotation of the magnetic turntable is installed on the back of the lifting platform, and a propulsion slide part for pushing the driving motor back and forth is provided on the base plate, and a brush head is installed on the rotating shaft end of the driving motor. When rust is removed from the inner groove of the bearing ring, the bearing ring is magnetically fixed on the magnetic turntable, the center of the bearing ring is aligned with the center of the magnetic turntable, and the propulsion slide part propels the driving motor to send the brush head into the bearing ring, and the magnetic turntable is driven to move up through the lifting platform so that the brush head contacts the inner groove of the bearing ring. The driving motor drives the brush head to rotate while the driving part drives the magnetic turntable to rotate, which can achieve comprehensive rust removal of the inner groove of the bearing ring by the brush head, and the rust removal effect is good and efficient.

[0024] 3. While achieving efficient rust removal, this invention also prioritizes environmental protection and energy conservation, minimizing environmental impact. The brush head friction removes rust, avoiding the generation of waste liquids associated with traditional liquid cleaning methods and reducing environmental pollution. The electromagnet is powered by a power source, achieving magnetic fixation, which is more energy-efficient and easier to control than traditional mechanical fixation methods.

[0025] 4. The present invention installs a counterweight balance block at the lower end of the box frame of the magnetic turntable to ensure that the turntable remains balanced during rotation and improve the stability of the rust removal process. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Reference Figure 2-14 As shown, the present invention provides a bearing ring inner groove rust removal device, including an outer cover housing 700, and further comprising: The push-type machine tool unit includes a base plate 100 and a push-type slide 300 mounted on the base plate 100. The push-type machine tool unit includes a base plate 100 and a push-type slide 300 mounted on the base plate 100. The push-type slide 300 is mounted on the drive motor 200, and the brush head is mounted on the end of the rotating shaft of the drive motor 200. The bearing ring fixing unit includes a lifting platform 400 installed on the base plate 100 and a rotatable magnetic turntable 500 installed on the lifting platform 400. A driving unit 600 for driving the rotation of the magnetic turntable 500 is installed on the back of the lifting platform 400. The bearing ring is magnetically fixed at the center of the magnetic turntable 500.

[0043] like Figure 2-Figure 5 As shown, the magnetic turntable 500 is rotatably mounted on the lifting platform 400, and a driving unit 600 for driving the rotation of the magnetic turntable 500 is installed on the back of the lifting platform 400, and a propulsion slide 300 for pushing the driving motor 200 back and forth is provided on the base plate 100. A brush head is installed on the rotating shaft end of the driving motor 200. When the inner groove of the bearing ring is derusted, the bearing ring is magnetically fixed to the magnetic turntable 500. On the top, the center of the bearing ring is aligned with the center of the magnetic turntable 500, and the sliding seat part 300 pushes the driving motor 200 to send the brush head into the bearing ring. The magnetic turntable 500 is driven upward by the lifting platform 400, so that the brush head contacts the inner groove of the bearing ring. The driving motor 200 drives the brush head to rotate while the driving part 600 drives the magnetic turntable 500 to rotate, which can achieve comprehensive rust removal of the inner groove of the bearing ring by the brush head, and the rust removal effect is good and efficient.

[0044] As a further preference of the above embodiment, Figure 12 As shown, the magnetic turntable 500 includes a casing 510 and an electromagnet 520 installed in the casing 510 , and an adsorption plate 530 is detachably installed at the opening of the casing 510 .

[0045] like Figure 14 As shown, the housing 510 includes a shell cylinder 511 and a box frame 512 arranged on the back of the shell cylinder 511, a shaft column 513 is installed at the center of the back of the shell cylinder 511, a power supply 514 for powering the electromagnet 520 is installed at the upper end of the box frame 512, and a counterweight balancing block 515 is installed at the lower end of the box frame 512.

[0046] like Figure 12-14 As shown, a micro camera 501 is installed at the center of the adsorption platen 530. The micro camera 501 is used to observe the contact between the brush head and the groove in the bearing ring. The adsorption platen 530 is provided with a diameter scale ring 531 on the end face for adsorbing the bearing ring, and is adsorbed with a support block 532 for positioning the bearing ring. When derusting bearing rings of different diameters, the outer ring of the bearing ring is aligned with the corresponding diameter scale ring 531 according to the diameter specification of the bearing ring, so that after the bearing ring is magnetically attracted to the adsorption platen 530, the center of the ring can be aligned with the center of the adsorption platen 530. When magnetically attracting the bearing ring, the support block 532 is first magnetically attracted to the corresponding diameter scale ring 531 to facilitate supporting the lower end of the bearing ring and facilitate positioning.

[0047] As a further preference of the above embodiment, Figure 12 As shown, the driving part 600 includes a support shaft frame 610 for connecting to the shaft column 513 at the back of the shell cylinder 511 and a supporting plate 620 fixedly set on the lifting platform 400, and a transmission member 630 is installed on the supporting plate 620.

[0048] The support shaft frame 610 includes a frame rod 611 detachably connected and installed on the back of the lifting platform 400 and a connecting shaft 612 axially connected to the middle of the frame rod 611 , and one end of the connecting shaft 612 is connected to the shaft column 513 .

[0049] The transmission member 630 includes a servo motor 631 fixedly mounted on the support plate 620 and a first transmission wheel 632 connected to the output end of the servo motor 631. A second transmission wheel 634 is mounted on the other end of the connecting shaft 612. A transmission belt 633 is arranged between the first transmission wheel 632 and the second transmission wheel 634. The diameter of the first transmission wheel 632 is smaller than the diameter of the second transmission wheel 634.

[0050] As a further preference of the above embodiment, Figures 8-11As shown, the lifting platform plate 400 includes a plate body 410 and positioning guide columns 420 connected to both sides of the plate body 410. The lower end of the plate body 410 is connected to a first pneumatic cylinder 430. The telescopic end of the first pneumatic cylinder 430 is connected to the lower end of the plate body 410. A circular opening 411 for installing the magnetic turntable 500 is opened in the middle of the plate body 410. The positioning guide columns 420 include sleeves 422 connected and installed on both sides of the plate body 410 and guide column rods 421 inserted in the sleeves 422.

[0051] As a further preference of the above embodiment, Figure 5-Figure 6 As shown, the propulsion slide portion 300 includes a guide rail 310 installed on the base plate 100 and a movable slide 320 installed on the guide rail 310. A second pneumatic cylinder 330 is installed on the base plate 100, and the telescopic end of the second pneumatic cylinder 330 is connected and installed on the slide 320.

[0052] As a further preference of the above embodiment, Figure 6-Figure 7 As shown, the brush head includes a mounting end 201 for connecting to the rotating shaft end of the driving motor 200 and a circular brush head 202 connected to the mounting end 201 .

[0053] like Figure 6-Figure 13 As shown, according to the diameter of the bearing ring, the outer ring of the bearing ring is aligned with the corresponding diameter scale ring 531, the bearing ring is magnetically attracted to the adsorption table 530, and the center of the bearing ring is aligned with the center of the adsorption table 530, the telescopic end of the second pneumatic cylinder 330 extends, driving the slide 320 to move toward the lifting table 400, and the brush head is sent into the bearing ring. The brush head and the groove in the bearing ring are in the same plane, and the telescopic end of the first pneumatic cylinder 430 drives the plate 410 to move upward. The contact between the brush head and the groove in the bearing ring is captured by the micro camera 501. After the brush head is fully in contact with the groove in the bearing ring, the telescopic end of the first pneumatic cylinder 430 stops moving upward, and the driving motor 200 drives the brush head to rotate while the driving unit 600 drives the magnetic turntable 500 to rotate, and the circular brush head 202 in contact with the inner groove achieves comprehensive rust removal of the inner groove. After rust removal is completed, the telescopic end of the first pneumatic cylinder 430 drives the plate body 410 to move down and back to its position, and the telescopic end of the second pneumatic cylinder 330 retracts, driving the slide 320 to return to its position, so that the brush head is moved out of the bearing ring. After the power supply 514 is turned off, the power supply to the electromagnet 520 is stopped, and the bearing ring after rust removal is completed is removed from the adsorption table 530.

[0054] like Figure 2-14 As shown, the working process of the bearing ring inner groove rust removal device of the present invention is as follows: (1) Preparation Place the bearing ring to be derusted on the adsorption platen 530 of the magnetic turntable 500. Align the outer ring of the bearing ring with the diameter scale ring 531 on the adsorption platen 530 according to the bearing ring's diameter. Use support blocks 532 to support and position the bearing ring, ensuring that the center of the bearing ring is aligned with the center of the adsorption platen 530. Turn on power supply 514, energizing electromagnet 520 and firmly magnetically securing the bearing ring to the adsorption platen 530.

[0055] (2) Brush head propulsion The second pneumatic cylinder 330 is activated, and its telescopic end extends, driving the slide 320 on the propulsion slide 300 to move along the guide rail 310 toward the lifting platform 400. This pushes the brush head (including the mounting end 201 and the circular brush head 202) mounted on the rotating shaft end of the drive motor 200 into the inner groove of the bearing ring, aligning the brush head and the inner groove in the same plane. The contact between the brush head and the inner groove of the bearing ring is monitored by the micro-camera 501 on the adsorption platform 530 to ensure precise contact with the inner groove. If the position of the brush head needs to be adjusted, the position of the slide 320 can be fine-tuned by controlling the extension and retraction of the second pneumatic cylinder 330.

[0056] (3) Rust removal process The first pneumatic cylinder 430 is activated, and its telescopic end extends upward, driving the lifting platform 400 upward. This in turn causes the magnetic turntable 500 and its bearing ring to move upward, bringing the brush head into close contact with the inner groove of the bearing ring. The drive motor 200 is activated, driving the brush head (round brush head 202) to rotate at high speed. Simultaneously, the servo motor 631 of the drive unit 600 is activated, driving the magnetic turntable 500 via the transmission member 630 (comprising a first transmission wheel 632, a transmission belt 633, and a second transmission wheel 634). During this process, the contact surface between the brush head and the inner groove of the bearing ring continuously changes, achieving comprehensive frictional rust removal of the inner groove. Throughout the rust removal process, the contact between the brush head and the inner groove is monitored in real time by a micro-camera 501 to ensure effective rust removal. If poor contact or incomplete rust removal is detected, parameters such as the extension and retraction of the first pneumatic cylinder 430 or the speed of the drive motor 200 can be adjusted promptly.

[0057] (4) Complete rust removal When rust removal is complete, the telescopic end of the first pneumatic cylinder 430 retracts, driving the lifting platform 400 downward, returning the magnetic turntable 500 and the bearing ring thereon to their initial positions, and separating the brush head from the groove within the bearing ring. The second pneumatic cylinder 330 is activated, and its telescopic end retracts, driving the slide 320 on the propulsion slide 300 back to its initial position along the guide rail 310, allowing the brush head to exit the groove within the bearing ring.

[0058] (5) Subsequent processing Turn off power 514, deactivating the electromagnet 520. The bearing ring is no longer attached to the adsorption platen 530. Remove the derusted bearing ring and inspect the inner groove to ensure complete removal of the rust. If multiple bearing rings need to be derusted, repeat the above steps, attaching each bearing ring to the magnetic turntable 500 and performing the derusting operation.

[0059] The implementation results show that the present invention adopts a dual motion mode of "rotation + propulsion". Through the rotation of the magnetic turntable and the propulsion of the brush head, all-round contact and friction between the brush head and the groove inside the bearing ring are achieved, thereby achieving an efficient and comprehensive rust removal effect. The bearing ring is fixed on the magnetic turntable, and stable fixation is achieved through the magnetic action of the electromagnet, and the turntable is driven to rotate by the driving part so that the bearing ring can rotate in all directions during the rust removal process. The brush head is driven back and forth by the propulsion slide part, so that the brush head can be accurately sent into the groove inside the bearing ring and closely contact with the surface of the inner groove to achieve comprehensive rust removal. The rust removal device for the groove inside the bearing ring of the present invention achieves comprehensive and efficient rust removal of the groove inside the bearing ring through the rotation of the magnetic turntable and the propulsion and rotation of the brush head. The whole process has a high degree of automation and is easy to operate. It can significantly improve the efficiency and quality of rust removal, is suitable for bearing rings of different specifications, and has a wide range of industrial application value.
