Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, specifically to a bearing inner ring polishing device suitable for textile machinery. Background Technology

[0002] Textile machinery is the general term for tools that process raw materials such as yarn, silk, and hemp into threads and then weave them into fabric. However, bearings are an important component in textile machinery. Their main function is to support the rotating body of the machine, reduce the coefficient of friction during its movement, and ensure its rotational accuracy. During the processing of shafts and bearings, the inner rings need to be polished so that the bearings can better cooperate with other components.

[0003] The working principle of some existing polishing devices is roughly as follows: the polishing roller is adjusted to contact the inner wall of the bearing inner ring, and the first set of motors drives the adjustment component to rotate, causing the second motor on the adjustment component and the polishing roller to revolve. At the same time, the rotation of the second motor drives the polishing roller to rotate, thereby achieving the grinding and polishing of the bearing inner ring. For example, the automatic grinding device for bearing inner rings with application number CN202121860618.7 and the polishing device for bearing inner rings with application number CN202420396801.3 both use this method for polishing. However, this polishing method requires the synchronous cooperation of two sets of motors, which increases the cost and energy consumption of the device. At the same time, the second motor needs to be connected to a power source. If a conductive slip ring is not used, the power cord will become tangled due to the revolution of the adjustment component. The use of a conductive slip ring further increases the cost, and the conductive slip ring also increases the complexity and maintenance difficulty of the device. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a bearing inner ring polishing device suitable for textile machinery, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bearing inner ring polishing device suitable for textile machinery, comprising a base and a fixed frame. A hydraulic rod is installed on the top of the fixed frame, and the output end of the hydraulic rod is connected to a movable plate. A drive motor is installed on the top of the movable plate, and a rotating plate is welded to the output end of the drive motor via a drive shaft. A spline shaft is installed on the top of the rotating plate via a mounting plate. A second movable opening is provided on one side of the top of the rotating plate. A second sliding groove is provided on the inner wall of the second movable opening, and an adjusting block is connected to the inside of the second sliding groove via a second slider. A spline tube is rotatably connected to the top of the adjusting block, and the spline tube is sleeved on and meshes with the outer surface of the spline shaft. A transmission bevel tooth is installed on the outer surface of the spline tube. A rotating shaft passes through the middle of the top of the adjusting block. A driven bevel tooth is fixed at the top end of the rotating shaft. A polishing roller is installed on the outer surface of the rotating shaft. A driving bevel tooth is fixed at one end of the spline shaft. A fixing bevel tooth ring is fixed in the middle of the bottom of the movable plate. A screw is threadedly connected to the inside of the rotating plate.

[0006] A servo motor is installed inside the upper part of the base. The output end of the servo motor is connected to a worm gear. A support plate is fixed inside the lower part of the base. Two sets of connecting shafts are fixed on the inner side of the support plate. A worm gear and a swing arm are fixed on the outer surface of each set of connecting shafts. A toggle groove is formed on the outer surface of the swing arm. A first movable opening is formed on both sides of the top of the base. A first sliding groove is formed on the inner wall of the movable opening. A translation arm is connected inside the first sliding groove through a first slider. A toggle shaft located inside the toggle groove is fixed at the bottom of the translation arm. A clamping member is fixed at one end of the translation arm.

[0007] Furthermore, the clamping member is provided in two sets, and both sets of clamping members are V-shaped, with a rubber layer on the inner side of the clamping member.

[0008] By adopting the above technical solution and utilizing the geometric adaptability of the V-shaped surface, the bearing inner ring outer circle is contacted by the symmetrical inclined side. Regardless of the inner ring diameter, it can be clamped and fixed by the V-shaped groove; the rubber layer provides elastic cushioning, making the clamping tighter.

[0009] Furthermore, two sets of sliding rods are fixed inside the lower part of the base. The sliding rods are "arc-shaped" and the swing arm slides in cooperation with the sliding rods.

[0010] By adopting the above technical solution, the radial displacement of the swing arm is limited by the trajectory guiding effect of the arc-shaped slide rod, so that it slides in an arc around the fixed connecting shaft, ensuring that the movement trajectory of the swing arm is accurate and controllable; the arc design of the slide rod matches the swing center of the swing arm, forming a rigid guiding constraint.

[0011] Furthermore, a knob is fixed to one end of the screw, and one end of the screw is rotatably connected to the adjusting block.

[0012] By adopting the above technical solution, when the knob rotates the screw, the screw and the adjusting block are rotatably connected (the screw rotates on its own, but the adjusting block does not rotate on its own), and the adjusting block is axially limited by the second movable port. Therefore, when the screw rotates, the adjusting block is pushed and pulled linearly along the screw axis.

[0013] Furthermore, a control panel is installed above the outer surface of the fixing frame, and the control panel is electrically connected to the hydraulic rod, servo motor and drive motor.

[0014] By adopting the above technical solution, staff can control the hydraulic rod, servo motor, and drive motor through the control panel.

[0015] Furthermore, the active bevel tooth meshes with the fixed bevel tooth ring, and the transmission bevel tooth meshes with the driven bevel tooth.

[0016] By adopting the above technical solution, the active bevel tooth meshes with the fixed bevel tooth ring, converting revolution into rotation; the transmission bevel tooth meshes with the driven bevel tooth to transmit power, causing the polishing roller to rotate. The power decomposition is achieved through mechanical bevel tooth meshing, simplifying the structure, improving the efficiency of polishing power transmission and the reliability of the equipment, eliminating the need for complex motor control, and completing the composite motion of inner ring polishing through pure mechanical transmission.

[0017] Furthermore, the worm gear is provided in two sets, and the worm is located between the two sets of worm gears, and the worm meshes with the two sets of worm gears.

[0018] By adopting the above technical solution, when the worm rotates, it drives two sets of worm wheels to rotate synchronously in opposite directions. The rotational power of the worm is evenly distributed to the worm wheels on both sides through the symmetrical meshing structure, so that the swing arm connecting the worm wheels can achieve symmetrical movement. This can ensure that the bearing inner ring is fixed with uniform force on both sides and accurate positioning, and avoid the workpiece displacement problem caused by unilateral drive.

[0019] Furthermore, a nut is threaded onto the outer surface of the rotating shaft, and the polishing roller is detached from the rotating shaft via the nut.

[0020] By adopting the above technical solution, the polishing roller can be fastened to the outer surface of the rotating shaft by rotating the nut. The polishing roller can be removed by loosening the nut during disassembly. This design utilizes the reliability of the threaded connection to achieve stable installation of the polishing roller. The quick disassembly and assembly of the nut facilitates the replacement of polishing rollers of different materials or sizes according to processing requirements, improves the adaptability of the equipment to diverse bearing inner ring polishing processes, simplifies the maintenance process, reduces replacement costs, and ensures that the coaxiality accuracy between the polishing roller and the rotating shaft meets the requirements of high-precision processing.

[0021] Furthermore, a limiting groove is provided inside the fixed frame, and the movable plate slides in conjunction with the limiting groove.

[0022] By adopting the above technical solution, the limiting groove constrains the movement trajectory of the movable plate, so that it can only slide in a straight line along the guide direction of the limiting groove, avoiding deviation or shaking, and ensuring that the movable plate moves smoothly under the drive of hydraulic rod or motor.

[0023] In summary, the present invention has the following main advantages:

[0024] 1. This utility model utilizes a coordinated design of a fixed bevel gear ring, a rotating plate, a driving bevel gear, a spline shaft, a spline tube, a transmission bevel gear, a driven bevel gear, a rotating shaft, a screw, and an adjusting block. During adjustment, the operator rotates the screw, driving the adjusting block to slide along the second movable opening on the inner side of the rotating plate. Simultaneously, the spline tube slides axially along the spline shaft, ensuring the polishing roller is tightly fitted against the inner wall of the bearing inner ring. After starting the motor, the drive shaft rotates the rotating plate, which in turn causes the spline shaft, rotating shaft, and polishing roller to revolve. When the spline shaft revolves with the rotating plate, the driving bevel gear at its end meshes with the fixed bevel gear ring, forcing it to rotate. The rotation is transmitted to the spline tube through the spline shaft, causing the spline tube to rotate synchronously. The transmission bevel teeth on the outer surface of the spline tube drive the driven bevel teeth to rotate, thereby driving the rotating shaft and polishing roller to rotate. Through the combined motion of the revolution and rotation of the polishing roller, the inner wall of the bearing inner ring can be polished uniformly in the whole circumference. Compared with the scheme that relies on dual motor drive in the background technology, this design uses a pure mechanical structure of bevel gear meshing and spline transmission to synchronously convert the motor power into revolution and rotation motion. There is no need to configure a second drive motor and conductive slip ring assembly, which simplifies the complexity of the device and effectively reduces the manufacturing cost and maintenance difficulty of the equipment.

[0025] 2. This utility model employs an innovative linkage design involving a servo motor, worm gear, two sets of worm wheels, a swing arm, a connecting shaft, a shifting groove, a shifting shaft, a first movable opening, a translation arm, a first slider, a first sliding groove, and clamping components. During the fixing process of the bearing inner ring, the servo motor drives the worm gear to rotate, which synchronously drives the two sets of worm wheels to rotate in opposite directions. This is transmitted through the connecting shaft, causing the two sets of swing arms to swing synchronously. During the swinging process, the shifting groove on the swing arm presses against the shifting shaft, forcing the first slider on the translation arm to slide laterally along the first sliding groove. This, in turn, pushes the translation arm to drive the clamping components to move in opposite linear directions, achieving precise clamping and positioning of the bearing inner ring. This design achieves power distribution through the precise transmission of the worm gear and worm wheels, and utilizes the geometric constraints of the swing arm and shifting structure to convert rotational motion into translational motion, ensuring that the two sets of clamping components move synchronously and symmetrically. This achieves the stability and reliability of the automated clamping process, significantly improving the clamping efficiency and positioning accuracy of the bearing inner ring.

Detailed Implementation

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of this utility model will be described below based on its overall structure.

[0035] Example 1: A bearing inner ring polishing device suitable for textile machinery, such as... Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the device includes a base 1 and a fixed frame 2. A hydraulic rod 3 is mounted on the top of the fixed frame 2, and the output end of the hydraulic rod 3 is connected to a movable plate 4. A protective cover is fixed to the bottom of the movable plate 4 to prevent accidental injury to personnel during high-speed rotation. A limit groove 7 is formed inside the fixed frame 2, and the movable plate 4 slides in conjunction with the limit groove 7. The limit groove 7 restricts the movement trajectory of the movable plate 4, allowing it to slide in a straight line only along the guide direction of the limit groove 7, preventing deviation or shaking, and ensuring that the movable plate 4 moves smoothly under the drive of the hydraulic rod 3 or the motor. A drive motor 5 is mounted on the top of the movable plate 4, and a rotating plate 10 is welded to the output end of the drive motor 5 via a drive shaft 9. A splined shaft 27 is mounted on the top of the rotating plate 10 via a mounting plate 26. A second movable opening 29 is provided on one side of the top. A second sliding groove 30 is provided on the inner wall of the second movable opening 29. An adjusting block 31 is connected to the inside of the second sliding groove 30 through a second slider 36. A spline tube 28 is rotatably connected to the top of the adjusting block 31. The spline tube 28 is sleeved on the outer surface of the spline shaft 27 and meshes with it. A transmission bevel tooth 33 is installed on the outer surface of the spline tube 28. A rotating shaft 32 passes through the middle of the top of the adjusting block 31. A driven bevel tooth 37 is fixed at the top of the rotating shaft 32. A polishing roller 35 is installed on the outer surface of the rotating shaft 32. A driving bevel tooth 34 is fixed at one end of the spline shaft 27. A fixing bevel tooth ring 8 is fixed in the middle of the bottom of the movable plate 4. A screw 20 is threadedly connected to the inside of the rotating plate 10.

[0036] See Figure 1 , Figure 3 and Figure 4 In the above embodiment, a knob is fixed at one end of the screw 20, and one end of the screw 20 is rotatably connected to the adjusting block 31. When the knob rotates, the screw 20 is rotatably connected to the adjusting block 31 (the screw 20 rotates on its own, but the adjusting block 31 does not rotate on its own). The adjusting block 31 is axially limited by the second movable port 29. Therefore, when the screw 20 rotates, the adjusting block 31 is pushed and pulled linearly along the axis of the screw 20.

[0037] See Figure 1 , Figure 3 and Figure 4 In the above embodiment, the active bevel tooth 34 meshes with the fixed bevel tooth ring 8, and the transmission bevel tooth 33 meshes with the driven bevel tooth 37 (lubricating oil is applied between the transmission bevel tooth 33 and the driven bevel tooth 37, and between the active bevel tooth 34 and the fixed bevel tooth ring 8, thereby reducing wear). The active bevel tooth 34 meshes with the fixed bevel tooth ring 8, converting revolution into rotation; the transmission bevel tooth 33 meshes with the driven bevel tooth 37 to transmit power, causing the polishing roller 35 to rotate. Power decomposition is achieved through mechanical bevel tooth meshing, simplifying the structure, improving the efficiency of polishing power transmission and equipment reliability, eliminating the need for complex motor control, and completing the composite motion of inner ring polishing through pure mechanical transmission.

[0038] Example 2: To make the bearing inner ring more stable during polishing, Example 2 is an improvement on Example 1. (See attached document for details.) Figures 1-2 A servo motor 11 is installed on the upper part of the base 1. The output end of the servo motor 11 is connected to a worm gear 12. A support plate 13 is fixed on the lower part of the base 1. Two sets of connecting shafts 14 are fixed on the inner side of the support plate 13. Worm gears 21 and swing arms 15 are fixed on the outer surfaces of the two sets of connecting shafts 14. A toggle groove 19 is opened on the outer surface of the swing arm 15. The inner wall of the toggle groove 19 is coated with lubricating oil to reduce wear with the toggle rod 18. A first movable opening 22 is opened on both sides of the top of the base 1. A first sliding groove 23 is opened on the inner wall of the movable opening. A translation arm 17 is connected to the inside of the first sliding groove 23 through a first slider 24. A toggle shaft 18 located inside the toggle groove 19 is fixed at the bottom of the translation arm 17. A clamping member 25 is fixed at one end of the translation arm 17.

[0039] See Figures 1-2 In the above embodiment, the clamping member 25 is provided in two sets, and both sets of clamping members 25 are V-shaped. The inner side of the clamping member 25 is provided with a rubber layer. Utilizing the geometric adaptability of the V-shaped surface, it contacts the outer circle of the inner ring of the bearing through the symmetrical inclined edge. Regardless of the diameter of the inner ring, it can be clamped and fixed through the V-shaped groove. The rubber layer provides elastic cushioning, making the clamping tighter.

[0040] See Figures 1-4 In the above embodiment, two sets of slide rods 16 are fixed inside the lower part of the base 1. The slide rods 16 are "arc-shaped" and the swing arm 15 slides in cooperation with the slide rods 16. The trajectory guidance effect of the arc-shaped slide rods 16 is used to limit the radial displacement of the swing arm 15 when it swings, so that it slides around the fixed connecting shaft 14 in an arc, ensuring that the movement trajectory of the swing arm 15 is accurate and controllable. The arc design of the slide rods 16 matches the swing center of the swing arm 15, forming a rigid guiding constraint.

[0041] See Figure 1 In the above embodiment, a control panel 6 is installed above the outer surface of the fixing frame 2, and the control panel 6 is electrically connected to the hydraulic rod 3, the servo motor 11 and the drive motor 5. The operator can control the hydraulic rod 3, the servo motor 11 and the drive motor 5 through the control panel 6.

[0042] See Figures 1-2In the above embodiment, the worm gear 21 is provided in two sets, and the worm 12 is located between the two sets of worm gears 21. The worm 12 meshes with the two sets of worm gears 21. When the worm 12 rotates, it drives the two sets of worm gears 21 to rotate synchronously in opposite directions. The rotational power of the worm 12 is evenly distributed to the two worm gears 21 through the symmetrical meshing structure, so that the swing arm 15 connecting the worm gears 21 can achieve symmetrical movement. This can ensure that the bearing inner ring is fixed with uniform force on both sides and accurate positioning, and avoid the workpiece displacement problem caused by unilateral drive.

[0043] Example 3: Since the polishing roller is a consumable, Example 2 is an improvement on Example 1 to facilitate its replacement. (See attached document for details.) Figure 4 and Figure 6 The outer surface of the rotating shaft 32 is threaded with a nut 38, and the polishing roller 35 is detachably connected to the rotating shaft 32 via the nut 38. Rotating the nut 38 can fasten the polishing roller 35 to the outer surface of the rotating shaft 32, and the polishing roller 35 can be removed by loosening the nut 38. This design utilizes the reliability of the threaded connection to achieve stable installation of the polishing roller 35, and the nut 38 allows for quick disassembly and assembly, facilitating the replacement of polishing rollers 35 of different materials or sizes according to processing requirements. This improves the equipment's adaptability to diverse bearing inner ring polishing processes, simplifies maintenance procedures, reduces replacement costs, and ensures that the coaxiality accuracy of the polishing roller 35 and the rotating shaft 32 meets the requirements of high-precision processing.

[0044] The implementation principle of this utility model is as follows: When the operator operates, the operator first places the bearing inner ring on the top of the base 1, and then starts the servo motor 11 through the control panel 6. The worm gear 12 drives the two sets of worm wheels 21 to rotate in opposite directions. Through the connecting shaft 14, the two sets of swing arms 15 swing synchronously. During the swing, the actuating groove 19 on the swing arm 15 presses against the actuating rod 18 (the actuating rod 18 is fixed to the bottom of the translation arm 17 and slides with the actuating groove 19), forcing the first slider 24 on the translation arm 17 to slide laterally along the first sliding groove 23. The clamping member 25 clamps the bearing inner ring with the V-shaped surface and the rubber layer. The hydraulic rod 3 pushes the movable plate 4 to move down along the limiting groove 7, rotates the screw 20, and the adjusting block 31 slides along the second movable opening 29. At this time, the spline tube 28 slides axially on the spline shaft 27 (the spline shaft 27... (The teeth of the spline tube 28 are always engaged to ensure continuous torque transmission) until the polishing roller 35 is in contact with the inner wall of the bearing inner ring. Then, the drive motor 5 is started. The rotation of the drive motor 5 causes the drive shaft 9 to drive the rotating plate 10 to rotate. When the rotating plate 10 revolves, the driving bevel tooth 34 rolls along the inner tooth surface of the fixed bevel tooth ring 8. Since the fixed bevel tooth ring 8 is fixed, the driving bevel tooth 34 is forced to rotate around its own axis, which drives the spline tube 28 to rotate synchronously through the spline shaft 27. The transmission bevel tooth 33 on the outer surface of the spline tube 28 meshes with the driven bevel tooth 37, transmitting the rotational motion to the rotating shaft 32, and finally driving the polishing roller 35. The self-rotation forms a composite motion trajectory of revolution and self-rotation, realizing uniform polishing of the bearing inner ring (a dust collection mechanism (existing technology, not shown) can be used during polishing to avoid debris getting stuck in the meshing transmission components). In this device, the tooth ratio of the active bevel tooth (34) to the fixed bevel tooth ring (8) is 1:3, and the tooth ratio of the transmission bevel tooth (33) to the driven bevel tooth (37) is 5:6, forming a fixed transmission coefficient K=2.5, ensuring that the speed of the drive motor 5 and the rotation speed of the polishing roller 35 are uniquely correlated, forming a speed matching transmission system.

[0045] When replacing the polishing roller 35, loosen the nut 38 to disassemble and remove the nut 38 and the washer. Then, pull out the old polishing roller 35 along the axis of the rotating shaft 32 and install the new polishing roller 35.

[0046] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
