Description

Technical Field

[0001] This invention relates to the field of bearing processing technology, and in particular to a polishing machine for processing self-lubricating bearings with flanged sleeves. Background Technology

[0002] Flange-type self-lubricating bearings are key mechanical components that integrate flange (or "flanging") and self-lubricating properties. They are particularly valuable for medium- and low-speed equipment, serving as an excellent core component. Their high efficiency stems from their self-lubricating capability. After production, the flanged end face of the flange-type self-lubricating bearing needs to be ground. Existing grinding equipment is mostly dual-station grinding, where one drive unit drives two grinding wheels, allowing for simultaneous grinding at both stations.

[0003] However, existing dual-station grinding devices require the operator to hold the bearing close to the side wall of the grinding wheel during grinding, which presents the following problems: 1. Grinding can easily injure the operator's hands; 2. Manual operation is prone to fatigue; 3. Grinding thickness is difficult to control, which can easily affect the yield rate of bearing production.

[0004] Therefore, this invention proposes a polishing machine for processing self-lubricating bearings with flanged sleeves. Summary of the Invention

The bearing is automatically fed in by the feeding and conveying mechanism, clamped by the clamping and conveying mechanism, and transported to the grinding station.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention integrates a feeding conveyor mechanism, a clamping conveyor mechanism, a lifting control mechanism, a leveling adjustment mechanism, and a grinding mechanism to form a complete automated grinding production line. The bearing is automatically fed in by the feeding conveyor mechanism, clamped by the clamping conveyor mechanism, and transported to the grinding station. The grinding mechanism automatically completes the grinding of the flanged end face, eliminating the need for operators to hold the bearing close to the grinding wheel throughout the entire process. This design completely avoids the safety hazard of hand injuries during manual operation, significantly reduces the labor intensity of operators, eliminates work interruptions caused by human fatigue, allows the equipment to operate continuously and stably for extended periods, and significantly improves production efficiency. This invention utilizes a control system internally connected to the feeding motor, second motor, horizontal adjustment motor, lifting adjustment motor, and grinding motor. This control system coordinates the timing of each mechanism in real time: when the feeding conveyor transports the bearing to the set position, the control system activates the clamping conveyor to deliver the bearing to the grinding station and maintain its clamping position; subsequently, the control system drives the lifting control mechanism to lower the grinding wheel to a preset height, simultaneously activating the grinding motor for grinding; after grinding, the control system instructs the lifting control mechanism to raise the grinding wheel and controls the clamping conveyor to remove the bearing. Furthermore, the control system can automatically send position adjustment commands to the horizontal adjustment mechanism and lifting control mechanism based on preset grinding cycles or times, achieving grinding wheel wear compensation and specification switching. Through this centralized control, the reliability, safety, and intelligence of the entire assembly line operation are ensured. In this invention, a horizontal adjustment mechanism is used to adjust the left and right positions of the grinding mechanism, and a lifting control mechanism is used to adjust the vertical height of the grinding mechanism. These two mechanisms work together to form a two-degree-of-freedom adjustment capability. On one hand, when processing self-lubricating bearings with flanged sleeves of different outer diameters, the horizontal adjustment mechanism can adjust the horizontal alignment of the grinding wheel, and the lifting control mechanism can adjust the contact height between the grinding wheel and the bearing end face. This allows the equipment to quickly adapt to the grinding needs of different product specifications without replacing any parts. On the other hand, during the use of the grinding wheel, the abrasive in its working area will gradually wear down. By controlling the horizontal adjustment mechanism and the lifting control mechanism in a coordinated manner through the control system, full utilization of the entire circumferential surface of the grinding wheel and even different areas along the axial direction can be achieved. This coordinated adjustment method avoids premature scrapping of the entire grinding wheel due to localized wear, effectively extending the effective service life of the grinding wheel, reducing the replacement frequency and consumable costs, and is particularly suitable for long-term continuous production conditions.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figure 1-3 As shown, a polishing machine for processing self-lubricating bearings with flanged sleeves includes a worktable 1. A cabinet 2 is located at the bottom of the worktable 1. The cabinet 2 houses the control system. A mounting box 3 is located on the top of the worktable 1. Two grinding production lines are symmetrically arranged on the top of the worktable 1, and the two grinding production lines have identical structures. Each grinding production line includes a feeding conveyor mechanism 4, a clamping conveyor mechanism 5, a lifting control mechanism 6, a leveling adjustment mechanism 7, and a grinding mechanism 8.

[0020] The feeding conveyor mechanism 4 is fixedly installed at the front side of one end of the top of the workbench 1. The feeding conveyor mechanism 4 is used to feed the self-lubricating bearing of the flange sleeve to be ground into the subsequent work station. In this embodiment, the feeding conveyor mechanism 4 includes two side plates 401, fixed feet 402, two rotating rollers 403, a first conveyor belt 404, and a feeding motor 405. Both side plates 401 are fixedly installed at the notch 10 at the top of the workbench 1 via fixed feet 402, and the two side plates 401 are symmetrically arranged. The two rotating rollers 403 are rotatably installed at the front and rear ends between the two side plates 401. The first conveyor belt 404 is disposed on the two rotating rollers 403. The feeding motor 405 is fixedly installed at the front right end of the side plate 401, and the output shaft of the feeding motor 405 is fixedly connected to the roller shaft of the rotating roller 403 at the front end between the side plates 401. When the feed motor 405 starts, the feed motor 405 drives the front roller 403 to rotate, and the roller 403 drives the first conveyor belt 404 to move, thereby conveying the bearing placed on the first conveyor belt 404 to the rear end.

[0021] To ensure the bearing does not shift during transport, limiting structures 9 are provided on both sides of the top feeding conveyor mechanism 4 of the workbench 1. The limiting structure 9 includes an L-shaped mounting base 901, a connecting rod 902, and a stop bar 903. The L-shaped mounting base 901 is fixedly mounted on the top of the workbench 1. The connecting rod 902 is fixedly connected to the upper end of the L-shaped mounting base 901, and is located at the upper end of the first conveyor belt 404. The stop bar 903 is fixedly sleeved on the end of the connecting rod 902 near the end of the first conveyor belt 404, and its lower end face slides against the upper surface of the first conveyor belt 404. The width between the two stop bars 903 matches the outer diameter of the bearing, thereby guiding the bearing to move stably along the middle region of the first conveyor belt 404.

[0022] The clamping and conveying mechanism 5 is fixedly installed at the rear end of the feeding conveying mechanism 4 on the top of the workbench 1, with the front end of the clamping and conveying mechanism 5 staggered vertically with the rear end of the feeding conveying mechanism 4. The clamping and conveying mechanism 5 is used to clamp the bearings fed by the feeding conveying mechanism 4 and continue conveying them to the grinding station. Specifically, the clamping and conveying mechanism 5 includes a horizontal plate 501, two L-shaped plates 502, multiple vertical rollers 503, two vertical conveyor belts 504, and two second motors 505. The horizontal plate 501 is located at the rear end of the first conveyor belt 404, and the top of the horizontal plate 501 is flush with the top of the first conveyor belt 404, allowing the bearings to smoothly transition from the end of the first conveyor belt 404 to the horizontal plate 501. The two L-shaped plates 502 are fixed to both sides of the horizontal plate 501. The multiple vertical rollers 503 are rotatably mounted in pairs at the bottom of different L-shaped plates 502. The two vertical conveyor belts 504 are fitted onto the vertical rollers 503 at the bottom of different L-shaped plates 502. Two second motors 505 are rotatably mounted at the top rear end positions of different L-shaped plates 502, and the output shafts of the second motors 505 are fixedly connected to the roller shafts of the vertical rollers 503. When the two second motors 505 start synchronously, they drive the vertical rollers 503 on their respective sides to rotate, and the vertical rollers 503 drive the two vertical conveyor belts 504 to move. The distance between the two vertical conveyor belts 504 is slightly smaller than the outer diameter of the bearing, thereby clamping the bearing and conveying it backward.

[0023] The front end of the mounting box 3 has an opening with two symmetrical notches 10, at which the feeding conveyor mechanism 4 is installed. Two openings 11 are formed on the rear end face of the mounting box 3, each corresponding to a different position on the grinding production line. The rear end of the clamping conveyor mechanism 5 passes through the openings 11, and the second motor 505 is located outside the mounting box 3. In this way, the clamping conveyor mechanism 5 can deliver the ground bearings from inside the mounting box 3 and collect them.

[0024] The horizontal adjustment mechanism 7 is fixedly installed inside the mounting box 3 at the upper end of the clamping and conveying mechanism 5, and is used to adjust the left and right positions of the grinding mechanism 8. The horizontal adjustment mechanism 7 includes an L-shaped fixed base 701, a U-shaped fixed frame 702, two horizontal limit rods 703, a horizontal adjustment screw 704, a horizontal adjustment motor 705, a drive block 706, and a T-shaped plate 707. The L-shaped fixed base 701 is fixedly connected to the position above the opening 11 on the rear side wall of the mounting box 3. The U-shaped fixed frame 702 is fixedly installed on the top of the L-shaped fixed base 701. The horizontal adjustment screw 704 is rotatably installed between the U-shaped fixed frames 702. The horizontal adjustment motor 705 is fixedly connected to the side wall of the U-shaped fixed frame 702, and the output shaft of the horizontal adjustment motor 705 is fixedly connected to the horizontal adjustment screw 704. The two horizontal limit rods 703 are fixedly connected to both sides of the horizontal adjustment screw 704 between the U-shaped fixed frames 702. The drive block 706 is threadedly connected to the horizontal adjusting screw 704, and the drive block 706 slides against the horizontal limiting rod 703. The T-shaped plate 707 is fixedly installed on the top of the drive block 706. When the horizontal adjusting motor 705 is started, the horizontal adjusting motor 705 drives the horizontal adjusting screw 704 to rotate, and the horizontal adjusting screw 704 drives the drive block 706 to move left and right linearly along the horizontal limiting rod 703, thereby causing the T-shaped plate 707 and the lifting control mechanism 6 and grinding mechanism 8 installed on the T-shaped plate 707 to move left and right as a whole.

[0025] The lifting control mechanism 6 is movably mounted on the output part of the horizontal adjustment mechanism 7 and is used to adjust the height of the grinding mechanism 8. The lifting control mechanism 6 includes two vertical limiting rods 601, two sliding sleeves 602, a top plate 603, a threaded rod 604, a threaded sleeve 605, and a lifting adjustment motor 606. The threaded sleeve 605 is fixedly mounted on the T-shaped plate 707. The two sliding sleeves 602 are fixedly mounted on both sides of the threaded sleeve 605 on the T-shaped plate 707. The threaded rod 604 is threadedly connected inside the threaded sleeve 605. The two vertical limiting rods 601 are slidably inserted into the sliding sleeves 602. The top plate 603 is located at the top of the two vertical limiting rods 601. The lifting adjustment motor 606 is fixedly mounted at the center of the top of the top plate 603, and the output shaft of the lifting adjustment motor 606 is fixedly connected to the upper end of the threaded rod 604. When the lifting adjustment motor 606 is started, the lifting adjustment motor 606 drives the threaded rod 604 to rotate. Since the threaded sleeve 605 is fixed on the T-shaped plate 707, the threaded rod 604 will move up and down relative to the threaded sleeve 605 while rotating, thereby driving the top plate 603, the vertical limit rod 601 and the grinding mechanism 8 connected to the bottom of the vertical limit rod 601 to move up and down together.

[0026] The grinding mechanism 8 is fixedly connected to the lower end of the lifting control mechanism 6 and is used to grind the self-lubricating bearing of the flange sleeve conveyed by the clamping and conveying mechanism 5. The grinding mechanism 8 includes a connecting plate 801, two support plates 802, a rotating shaft 803, a grinding wheel 804, a first coupling 805, a connecting shaft 806, a second coupling 807, an end plate 808, and a grinding motor 809. The connecting plate 801 is fixedly connected to the bottom of the two vertical limiting rods 601, and the top of the connecting plate 801 is rotatably engaged with the bottom of the threaded rod 604. The two support plates 802 are fixedly connected to the bottom of the connecting plate 801. One end of the rotating shaft 803 is rotatably connected to the support plate 802, and the other end of the rotating shaft 803 is connected to the flange of the connecting shaft 806 through the first coupling 805. The connecting shaft 806 is rotatably engaged with the other support plate 802. The grinding wheel 804 is mounted on the rotating shaft 803 and is positioned directly above the clamping and conveying mechanism 5. The end plate 808 is fixedly connected to the outer bottom of the connecting plate 801. The grinding motor 809 is fixedly mounted on the end face of the end plate 808 away from the support plate 802, and the output shaft of the grinding motor 809 is connected to the end of the connecting shaft 806 away from the grinding wheel 804 via a second coupling 807. When the grinding motor 809 starts, it drives the connecting shaft 806 to rotate via the second coupling 807. The connecting shaft 806 then drives the rotating shaft 803 to rotate via the first coupling 805, which in turn drives the grinding wheel 804 to rotate, thereby grinding the flanged end face of the bearing.

[0027] The control system is located inside cabinet 2 and is electrically connected to the feed motor 405, the second motor 505, the horizontal adjustment motor 705, the lifting adjustment motor 606, and the grinding motor 809. The control system coordinates the automated workflow of the entire polishing machine. During operation, the control system first starts the feed motor 405, and the first conveyor belt 404 begins operation. The operator places the self-lubricating bearings of the flange sleeves to be ground onto the first conveyor belt 404 one by one or continuously. Guided by the limiting structure 9, the bearings move stably backward. When the bearings reach the end of the first conveyor belt 404 and transition onto the horizontal plate 501, the control system starts the two second motors 505, and the two vertical conveyor belts 504 begin to rotate in opposite directions, clamping the bearings and conveying them backward.

[0028] The control system has a pre-set grinding station position. When the bearing is conveyed by the clamping and conveying mechanism 5 to directly below the grinding wheel 804, the control system pauses the second motor 505, allowing the bearing to remain at the grinding station. Subsequently, the control system activates the lifting and adjusting motor 606, which drives the threaded rod 604 to rotate, causing the grinding mechanism 8 to descend until the grinding wheel 804 contacts the flanged end face of the bearing and reaches the preset grinding pressure or height. Then, the control system activates the grinding motor 809, causing the grinding wheel 804 to rotate at high speed and grind the bearing end face. After grinding continues for a preset time, the control system first shuts off the grinding motor 809, then reverses and activates the lifting and adjusting motor 606 to lift the grinding wheel 804 away from the bearing surface. Finally, the control system restarts the second motor 505, sending the ground bearing out from the rear end of the clamping and conveying mechanism 5 and into the collection container.

[0029] For bearings of different specifications, the control system can work with the horizontal adjustment mechanism 7 and the lifting control mechanism 6 for rapid adjustment. When the outer diameter of the bearing changes, the operator inputs the new specification parameters through the control panel. The control system automatically calculates the required horizontal centering position and height position of the grinding wheel 804, and then sends commands to the horizontal adjustment motor 705 and the lifting adjustment motor 606 respectively, so that the grinding wheel 804 moves to the correct position. Similarly, when the surface of the grinding wheel 804 becomes worn after a period of use, the control system can automatically control the horizontal adjustment motor 705 to fine-tune the axial position of the grinding wheel 804 at certain intervals or according to a preset program, while simultaneously controlling the lifting adjustment motor 606 to fine-tune the height of the grinding wheel 804, so that the unworn area of ​​the grinding wheel 804 participates in the grinding work. This linkage adjustment method can make full use of the entire circumferential surface and axial area of ​​the grinding wheel 804, significantly extending the service life of the grinding wheel 804.

[0030] The two symmetrically arranged grinding production lines can operate independently or synchronously. The control system controls each motor on the two production lines separately, without interference. When one production line needs to replace the 804 grinding wheel or undergo maintenance, the other production line can continue to operate, ensuring uninterrupted production.
