Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, and specifically discloses a vibratory polishing machine for bearing processing. Background Technology

[0002] Bearings, as core components of mechanical transmission systems, support rotating shafts and reduce frictional resistance, and are widely used in automobiles, aerospace, industrial robots, and other fields. Their precision and surface quality directly affect the operating efficiency and lifespan of equipment. To meet the requirements of high-speed and low-noise operation, bearings typically require precision machining and surface polishing. Vibratory polishing machines, as highly efficient surface treatment equipment, use vibration to create friction between abrasive materials and the bearing surface, removing burrs, oxide layers, and improving surface finish; this is a crucial step in the bearing manufacturing process.

[0003] Traditional vibratory polishing machines mainly consist of a vibratory motor, a vibratory groove, and a support mechanism. The vibratory motor drives the vibratory groove to vibrate at high frequency, ensuring full contact between the abrasive and the bearing to achieve polishing. However, this technology has the following significant problems:

[0004] 1. Difficulty in separating abrasive from workpiece: After polishing, the abrasive and bearing are mixed in the vibrating tank. Especially when processing a large number of small bearings in batches, the abrasive needs to be searched and sorted out one by one from the vibrating tank. Manual sorting is extremely inefficient and a waste of time.

[0005] 2. Abrasive splashing pollutes the environment: During vibration, abrasive material is easily splashed out from the opening of the vibration tank and scattered around the equipment, requiring manual cleaning and increasing cleaning costs.

[0006] Therefore, a vibratory polishing machine for bearing processing is needed to solve the above problems. Utility Model Content

[0007] This utility model proposes a vibratory polishing machine for bearing processing, which facilitates the separation of abrasive from bearings, avoids the need for manual searching and sorting of bearings from abrasive, and significantly improves work efficiency; at the same time, it effectively prevents abrasive from splashing out from the opening of the vibratory groove during polishing, reduces the cleaning work around the equipment, and lowers subsequent cleaning costs.

[0008] This utility model is implemented as follows: a vibratory polishing machine for bearing processing includes a base plate and a polishing tank, and an auxiliary separation mechanism, a protective mechanism and a vibration mechanism are provided above the base plate;

[0009] The auxiliary separation mechanism includes a frame, with a connecting frame fixedly connected between the inner wall of the frame and the outer wall of the polishing tank. A circular plate is fixedly connected through the lower end of the polishing tank, and multiple screening holes are opened through the outer wall of the circular plate. A protective box is provided below the circular plate, and a rotating column is rotatably connected to the upper end of the protective box. Multiple sealing strips are fixedly connected to the outer wall of the rotating column. A permanent magnet stepper motor with its output end fixedly connected to the rotating column is installed inside the protective box. A through groove is opened through the right end of the frame, and a guide trough is fixedly connected to the right end of the frame. A collection frame is provided below the guide trough.

[0010] The protective mechanism includes a central column fixedly connected to the upper end of the circular plate, a threaded cylinder fixedly connected to the upper end of the central column, a screw threadedly connected to the inside of the threaded cylinder, and a protective cover fixedly connected to the upper end of the screw, which abuts against the upper end of the polishing groove.

[0011] As a preferred embodiment of the bearing processing vibratory polishing machine of this utility model, the vibration mechanism includes two support platforms fixedly connected to the upper end of the base plate. Multiple vibration springs distributed front to back and fixedly connected to the lower end of the frame are fixedly connected to the upper ends of the two support platforms. Vibration motors are installed at both the left and right ends of the frame.

[0012] As a preferred embodiment of the vibratory polishing machine for bearing processing according to this utility model, a guide plate that passes through a groove is fixedly connected to the bottom end of the inner wall of the frame, and the upper end surface of the guide plate and the bottom surface of the inner wall of the guide groove are both inclined surfaces that are coplanar with each other.

[0013] In a preferred embodiment of the bearing processing vibratory polishing machine of this utility model, the upper ends of the plurality of sealing strips are left with gaps from the circular plate.

[0014] As a preferred embodiment of the vibratory polishing machine for bearing processing according to this utility model, a plurality of fixing rods are fixedly connected between the outer wall of the protective box and the outer wall of the polishing tank.

[0015] As a preferred embodiment of the vibratory polishing machine for bearing processing according to this utility model, the upper end of the base plate is provided with a positioning groove, and the bottom end of the collection frame extends into the interior of the positioning groove.

[0016] As a preferred embodiment of the vibratory polishing machine for bearing processing according to this utility model, the left and right ends of the base plate are both fixedly connected to mounting plates with multiple mounting holes.

[0017] The beneficial effects of this utility model are:

[0018] 1. During use, place the bearing to be polished and the abrasive into the polishing tank. By rotating the handle at the top of the protective cover, the screw is screwed into the threaded cylinder fixed by the central column, causing the protective cover to move downwards until its lower end tightly abuts against the edge of the upper opening of the polishing tank, forming a closed space. During vibratory polishing, the protective cover remains stable through the threaded engagement between the screw and the threaded cylinder, tightly covering the upper end of the polishing tank, preventing the abrasive from splashing out of the polishing tank during polishing, reducing cleaning work around the equipment, and lowering subsequent cleaning costs.

[0019] 2. After polishing, the permanent magnet stepper motor inside the protective box drives the rotating column to rotate at a set angle, causing the sealing strip fixed to its outer wall to rotate and completely misalign with the screening hole, opening the screening hole. Under vibration, the abrasive falls through the screening hole into the lower protective box area, passes through the guide plate and trough into the guide trough, and finally falls into the collection frame. Bearings larger than the screening hole are blocked by the circular plate and left in the polishing tank, achieving automatic separation. Then, the sealing strip covers the screening hole again, the screw is rotated in the opposite direction to raise and remove the protective cover, and the polished bearing can be directly removed from the polishing tank, avoiding the need for manual searching and sorting of bearings from the abrasive, significantly improving work efficiency.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0028] Please see Figure 1-5 A vibratory polishing machine for bearing processing includes a base plate 1 and a polishing tank 4. An auxiliary separation mechanism, a protective mechanism and a vibration mechanism are provided above the base plate 1.

[0029] The auxiliary separation mechanism includes a frame 2. A connecting frame 3 is fixedly connected between the inner wall of the frame 2 and the outer wall of the polishing tank 4. A circular plate 5 is fixedly connected through the lower end of the polishing tank 4. Multiple screening holes 10 are opened through the outer wall of the circular plate 5. A protective box 6 is set below the circular plate 5. A rotating column 8 is rotatably connected to the upper end of the protective box 6. Multiple sealing strips 9 are fixedly connected to the outer wall of the rotating column 8. A permanent magnet stepper motor 23 with its output end fixedly connected to the rotating column 8 is installed inside the protective box 6. A through groove 22 is opened through the right end of the frame 2. A guide groove 16 is fixedly connected to the right end of the frame 2. A collection frame 17 is set below the guide groove 16.

[0030] The protective mechanism includes a central column 11 fixedly connected to the upper end of the circular plate 5, a threaded cylinder 12 fixedly connected to the upper end of the central column 11, a screw 13 connected to the internal thread of the threaded cylinder 12, and a protective cover 14 fixedly connected to the upper end of the screw 13, which abuts against the upper end of the polishing groove 4.

[0031] In this embodiment: When in use, the bearing to be polished and the abrasive are first placed into the polishing tank 4. Then, the screw 13 is aligned with the threaded cylinder 12, which is fixed by the central column 11. Then, the protective cover 14 is rotated by the handle installed on the upper end of the protective cover 14, which drives the screw 13 to rotate. Thus, the screw 13 can be screwed into the inside of the threaded cylinder 12. When the screw 13 rotates, it drives the protective cover 14 to move downward until the lower end of the protective cover 14 is tightly abutted against the edge of the upper opening of the polishing tank 4, forming a closed space.

[0032] At this time, the permanent magnet stepper motor 23 in the protection box 6 is in a power-off state. The permanent magnet stepper motor 23 has a self-locking function, which can keep the rotating column 8 from rotating in the power-off state. The upper end of the sealing strip 9 on the rotating column 8 is in clearance fit with the lower end face of the circular plate 5, and the sealing strip 9 covers the screening hole 10 to prevent the abrasive from leaking out from the bottom of the polishing tank 4. The bottom end of the collection frame 17 is embedded in the positioning groove 18 of the base plate 1 to ensure that the position is fixed.

[0033] The polishing tank 4 is then made to vibrate at high frequency by a vibration mechanism. The bearing and the abrasive rub against each other in the polishing tank 4 as they vibrate, thus achieving surface polishing. During this process, the protective cover 14 is kept stable by the threaded engagement of the screw 13 and the threaded cylinder 12, tightly covering the upper end of the polishing tank 4 to prevent the abrasive from splashing out of the polishing tank 4 during the polishing process, reducing the cleaning work around the equipment and lowering the subsequent cleaning costs.

[0034] After polishing is completed, the permanent magnet stepper motor 23 in the protection box 6 is started. Its output end drives the rotating column 8 to rotate at a set angle, which drives the multiple sealing strips 9 fixed on the outer wall of the rotating column 8 to rotate at a certain angle. This allows the sealing strips 9 to be completely misaligned with the screening hole 10, the screening hole 10 to open, the diameter of the screening hole 10 to be larger than the particle size of the abrasive, and the vibration motor 21 to continue vibrating. The abrasive in the polishing tank 4 falls through the screening hole 10. Under the action of gravity, the abrasive slides along the guide plate 15, enters the guide trough 16 through the through groove 22, and finally falls into the collection frame 17 below. During this process, the bearing is blocked by the circular plate 5 because its size is larger than the diameter of the screening hole 10, and is retained in the polishing tank 4, thereby realizing the automatic separation of the abrasive and the bearing.

[0035] After the abrasive is discharged, the permanent magnet stepper motor 23 rotates the sealing strip 9 to cover the screening hole 10 again, blocking the abrasive channel. The screw 13 is rotated in the opposite direction to lift and remove the protective cover 14, so that the polished bearing can be directly taken out from the polishing tank 4. This avoids the need for manual searching and sorting of bearings from the abrasive, significantly improving work efficiency. Then, the abrasive inside the positioning groove 18 is directly poured into the polishing tank 4 for the next polishing.

[0036] As a technical optimization of this utility model, the vibration mechanism includes two support platforms 19 fixedly connected to the upper end of the base plate 1. Multiple vibration springs 20 distributed front to back and fixedly connected to the lower end of the frame 2 are fixedly connected to the upper end of each of the two support platforms 19. Vibration motors 21 are installed at both the left and right ends of the frame 2.

[0037] In this embodiment: the vibration motors 21 located at the left and right ends of the frame 2 are started. The vibration force generated by the vibration motors 21 is transmitted to the polishing tank 4 through the frame 2 and the connecting frame 3. Since the lower end of the frame 2 is connected to the support platform 19 on the base plate 1 through multiple vibration springs 20, the vibration springs 20 provide elastic support and amplify the vibration effect, so that the polishing tank 4 forms high-frequency vibration. The bearings and abrasives rub against each other in the polishing tank 4 with the vibration, so as to achieve surface polishing treatment.

[0038] As a technical optimization of this utility model, a guide plate 15 that passes through the groove 22 is fixedly connected to the bottom end of the inner wall of the frame 2. The upper end surface of the guide plate 15 and the bottom surface of the inner wall of the guide groove 16 are both inclined surfaces that are coplanar with each other.

[0039] In this embodiment: the upper end face of the guide plate 15 and the bottom surface of the inner wall of the guide groove 16 are coplanar inclined surfaces. When the abrasive falls into the area of ​​the protective box 6 through the screening hole 10, it slides along the inclined surface of the guide plate 15 under the action of gravity, enters the guide groove 16 through the through groove 22, and finally slides down to the collection frame 17.

[0040] As a technical optimization of this utility model, a gap is left between the upper ends of the multiple sealing strips 9 and the circular plate 5.

[0041] In this embodiment, a 1mm gap is left between the upper end of the sealing strip 9 and the lower end face of the circular plate 5. This ensures that the sealing strip 9 does not directly rub against the circular plate 5 when the rotating column 8 rotates, reducing mechanical wear, and also ensures that the sealing strip 9 seals the screening hole 10 to prevent the abrasive from falling.

[0042] As a technical optimization of this utility model, multiple fixing rods 7 are fixedly connected between the outer wall of the protective box 6 and the outer wall of the polishing groove 4.

[0043] In this embodiment, the protective box 6 and the polishing tank 4 are connected by a fixing rod 7 to ensure that the protective box 6 remains relatively stationary with respect to the polishing tank 4 during vibration.

[0044] As a technical optimization of this utility model, a positioning groove 18 is provided at the upper end of the base plate 1, and the bottom end of the collection frame 17 extends into the interior of the positioning groove 18.

[0045] In this embodiment: by setting the positioning groove 18, the placement position of the collection box 17 is positioned, thereby improving the accuracy of material receiving.

[0046] As a technical optimization of this utility model, the left and right ends of the base plate 1 are fixedly connected with mounting plates having multiple mounting holes.

[0047] In this embodiment: the mounting plates at both ends of the base plate 1 are bolted through the mounting holes, which can fix the equipment to the workbench or the ground, enhance the vibration resistance of the whole machine, and prevent the equipment from shifting or tipping over during high-speed vibration.

[0048] The working principle and usage process of this utility model are as follows: When in use, first place the bearing to be polished and the abrasive into the polishing tank 4, then align the screw 13 with the threaded cylinder 12, which is fixed by the central column 11. Then, rotate the protective cover 14 by the handle installed on the upper end of the protective cover 14, which will drive the screw 13 to rotate, so that the screw 13 can be screwed into the inside of the threaded cylinder 12. When the screw 13 rotates, it will drive the protective cover 14 to move downward until the lower end of the protective cover 14 is tightly abutted against the edge of the upper opening of the polishing tank 4, forming a closed space.

[0049] At this time, the permanent magnet stepper motor 23 in the protection box 6 is in a power-off state. The permanent magnet stepper motor 23 has a self-locking function, which can keep the rotating column 8 from rotating in the power-off state. The upper end of the sealing strip 9 on the rotating column 8 is in clearance fit with the lower end face of the circular plate 5, and the sealing strip 9 covers the screening hole 10 to prevent the abrasive from leaking out from the bottom of the polishing tank 4. The bottom end of the collection frame 17 is embedded in the positioning groove 18 of the base plate 1 to ensure that the position is fixed.

[0050] Start the vibration motors 21 located at the left and right ends of the frame 2. The vibration force generated by the vibration motors 21 is transmitted to the polishing tank 4 through the frame 2 and the connecting frame 3. Since the lower end of the frame 2 is connected to the support platform 19 on the base plate 1 through multiple vibration springs 20, the vibration springs 20 provide elastic support and amplify the vibration effect, so that the polishing tank 4 forms high-frequency vibration. The bearings and abrasives rub against each other in the polishing tank 4 with the vibration, so as to achieve surface polishing. During this process, the protective cover 14 is kept stable by the threaded engagement of the screw 13 and the threaded cylinder 12, tightly covering the upper end of the polishing tank 4, preventing the abrasives from splashing out from the inside of the polishing tank 4 during the polishing process, reducing the cleaning work around the equipment, and reducing the subsequent cleaning cost.

[0051] After polishing is completed, the permanent magnet stepper motor 23 in the protection box 6 is started. Its output end drives the rotating column 8 to rotate at a set angle, which drives the multiple sealing strips 9 fixed on the outer wall of the rotating column 8 to rotate at a certain angle. This allows the sealing strips 9 to be completely misaligned with the screening hole 10, the screening hole 10 to open, the diameter of the screening hole 10 to be larger than the particle size of the abrasive, and the vibration motor 21 to continue vibrating. The abrasive in the polishing tank 4 falls through the screening hole 10. Since the upper end surface of the guide plate 15 and the bottom surface of the inner wall of the guide groove 16 are coplanar inclined surfaces, the abrasive slides along the guide plate 15 under the action of gravity, enters the guide groove 16 through the groove 22, and finally falls into the collection frame 17 below. During this process, the bearing is blocked by the circular plate 5 because its size is larger than the diameter of the screening hole 10, and is retained in the polishing tank 4, thereby realizing the automatic separation of the abrasive and the bearing.

[0052] After the abrasive is discharged, the permanent magnet stepper motor 23 rotates the sealing strip 9 to cover the screening hole 10 again, blocking the abrasive channel. The screw 13 is rotated in the opposite direction to lift and remove the protective cover 14, so that the polished bearing can be directly taken out from the polishing tank 4. This avoids the need for manual searching and sorting of bearings from the abrasive, which significantly improves work efficiency. The collection frame 17 can be taken out from the positioning groove 18, and the abrasive inside the positioning groove 18 can be directly poured into the polishing tank 4 for the next polishing.

[0053] It should be noted that both the permanent magnet stepper motor 23 and the vibration motor 21 are electrically connected to the controller and are equipped with an operation panel. The controller integrates a start / stop button, a vibration frequency adjustment knob, and a control switch for opening and closing the screening hole 10. The operator inputs commands through the operation panel, and the controller sends pulse signals to the permanent magnet stepper motor 23 to control the rotation angle of the rotating column 8. At the same time, it outputs frequency conversion signals to the vibration motor 21 to adjust the vibration parameters, thereby realizing the automated control of the abrasive separation and polishing process. Its control structure is a mature existing technology and is not shown in the figure.
