Description

Technical Field

[0001] This invention belongs to the field of bearing assembly tool technology, specifically a bearing assembly auxiliary tool. Background Technology

[0002] Bearings are crucial components whose primary function is to support rotating mechanical parts, reduce friction during movement, and ensure rotational accuracy. In steel smelting and production, numerous conveying and cleaning processes are involved, all requiring the use of bearings for their rotating rollers. However, steel production environments are typically characterized by high loads, high speeds, high humidity, and potential chemical corrosion, as seen in processes like cleaning and annealing. In such conditions, bearings bear the primary load and wear. Severe wear or failure of bearings can lead to anything from malfunctioning rotating rollers to equipment failures or fires. Therefore, it is essential to monitor bearing wear and replace them promptly when severe wear is detected.

[0003] In factories, the assembly of rotary roller bearing housings is mostly done manually, using a hammer and key to strike the bearing. During this process, care must be taken to ensure that the key is pressed against the inner ring end face of the bearing and does not contact the outer ring to avoid damaging the bearing. At the same time, care must be taken to control the striking force to avoid breaking the bearing. However, in actual operation, it is difficult to ensure that the position of the key remains unchanged and the striking force is stable. Therefore, the efficiency and quality of manual assembly of bearings are not high. In response, the factory has made corresponding improvements. By designing a sleeve, the sleeve is placed on the outside of the shaft during bearing installation, with its end in contact with the bearing. Then, employees only need to tap the sleeve to push the bearing into the bearing housing. Compared with the key, tapping the sleeve is easier to control the force, which improves the assembly quality and efficiency to a certain extent. However, this method requires two people to work together, one person to tap and the other to hold the sleeve to limit its movement, resulting in a waste of human resources. In addition, different sizes of sleeves need to be designed and produced for different sizes of rotating rollers, which is also a waste of resources.

[0004] Therefore, the present invention provides a bearing assembly auxiliary tool. Summary of the Invention

[0007] Preferably, the pressing rod consists of a horizontal part and a vertical part, which together form an L-shaped pressing rod. The bending part of the pressing rod is rounded. The vertical part of the pressing rod passes through the limiting sleeve and is slidably connected to it. The pressing assembly also includes a pressing block fixedly connected to the outside of the pressing rod. The side of the pressing block away from the pressing rod is inclined. A return spring is fixedly connected between the pressing block and the limiting sleeve, and the return spring is sleeved on the outside of the pressing rod. A movable extrusion ring is slidably connected to the outside of the pressing block. The extrusion ring has a guide groove inside that matches the pressing block. The extrusion ring is slidably connected to the outside of the limiting sleeve.

[0008] Preferably, a rotating bearing is fixedly connected to the side of the extrusion ring near the sliding plate, and a rotating handle is fixedly connected to the side of the rotating bearing away from the extrusion ring.

[0010] Preferably, a snap-fit ​​block is fixedly connected to the side of the pressing rod away from the limiting sleeve. The snap-fit ​​block is designed in the shape of a right trapezoid, and multiple slots are opened on the inclined surface of the snap-fit ​​block.

[0011] Preferably, a connecting sleeve is provided inside the limiting sleeve and on the side away from the pressing rod. The connecting sleeve is fixedly connected to the transmission screw. A limiting component is provided inside the connecting sleeve. The limiting component is used to limit the positioning shaft when pressing the bearing and to limit the pressing rod when disassembling the bearing.

[0012] Preferably, the limiting component includes multiple sliding sleeves, which are slidably sleeved together and slidably connected inside the connecting sleeve. The telescopic ends of the multiple sliding sleeves and the ends of the connecting sleeves away from the transmission screw are all chamfered, and the chamfer angles are matched. An electric telescopic rod is fixedly connected between the innermost sliding sleeve and the connecting sleeve, and a rubber sleeve is sleeved on the outside of the pressing rod.

[0013] Preferably, the bottom ends of the sliding plate and the mounting plate are both fixedly connected to multiple hydraulic rods, the output ends of the hydraulic rods are fixedly connected to fastening rods, and the surface of the remote control vehicle body is provided with multiple slots that are adapted to the fastening rods.

[0014] Preferably, a laser emitter is fixedly connected to the innermost surface of the sliding sleeve, and the center of the laser emitter and the center of the sliding sleeve are on the same axis.

[0015] Preferably, a telescopic ring is fixedly connected to the side of the extrusion ring away from the rotating bearing, and a limit ring is fixedly connected to the side of the telescopic ring away from the extrusion ring.

[0016] The beneficial effects of this invention are as follows: 1.

[0017] 2. The bearing assembly auxiliary tool of the present invention controls multiple pressure rods to converge, thereby causing the locking blocks to converge. At this time, the remote-controlled vehicle moves and causes the locking blocks to extend into the interior of the bearing to be disassembled. Then, the pressure rods disperse and cause the multiple locking blocks to disperse until the inclined surface of the locking blocks contacts the inner ring of the bearing to be disassembled and presses and locks it. Then, the remote-controlled vehicle moves again and moves away from the bearing to be disassembled, thereby using the friction between the locking blocks and the bearing to be disassembled to pull the bearing to be disassembled out of the bearing housing, thereby achieving the effect of automatic bearing disassembly.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 6 As shown in the embodiment of the present invention, a bearing assembly auxiliary tool includes a drive motor 1. The output end of the drive motor 1 is fixedly connected to a transmission screw 2 via a coupling. A sliding plate 3 is threadedly connected to the outside of the transmission screw 2. A limiting sleeve 4 is fixedly connected to the side of the sliding plate 3 away from the drive motor 1. A pressing component is provided inside the limiting sleeve 4. The pressing component includes multiple movable pressing rods 5. The pressing component controls the multiple pressing rods 5 to converge and disperse to adapt to bearings of different sizes. When assembling the bearing using the embodiments of the present invention, refer to the attached diagram. Figure 2As shown, the bearing 26 to be installed and the bearing housing 27 need to be sequentially fitted onto the outside of the positioning shaft. Then, the end of the positioning shaft is inserted into the limiting sleeve 4. At this time, the pressing rod 5 covers the outside of the positioning shaft but does not fit against it. Then, the pressing assembly is activated, which drives multiple pressing rods 5 to converge until the pressing rods 5 are in contact with the outer surface of the positioning shaft. At this time, the inner diameter of the multiple pressing rods 5 is the same as the diameter of the positioning shaft. Since the bearing 26 to be installed is compatible with the positioning shaft, and the diameter of the pressing rod 5 is set in advance to be smaller than the thickness of the inner ring end face of the bearing 26 to be installed, the pressing rod 5 will definitely contact the inner ring end face of the bearing 26 to be installed. This effectively avoids the situation where the outer ring of the bearing 26 to be installed is squeezed during installation, affecting the installation result or causing damage to the bearing 26 to be installed. By setting the pressing assembly, the multiple pressing rods 5 are adjusted to converge. The device can be dispersed to accommodate bearings 26 of different sizes, thus improving its applicability. After the pressure rod 5 is adjusted, the drive motor 1 is started to run, driving the transmission screw 2 to rotate. The transmission screw 2 drives the sliding plate 3 to slide through the thread, thereby pushing the limit sleeve 4 to move. The movement of the limit sleeve 4 will push the pressure rod 5 to slide on the surface of the positioning shaft, thus pushing the pressure rod 5 to slide on the surface of the positioning shaft. The sliding of the pressure rod 5 pushes the bearing 26 to be installed and presses it into the bearing seat 27, thereby realizing the assembly of the bearing. This method replaces the traditional manual hammering. The pressure applied to the bearing 26 by the drive motor 1 is more stable, which can effectively avoid the situation where the force cannot be controlled during manual hammering, resulting in bearing damage. This improves the installation quality. At the same time, the embodiment of the present invention only requires one employee to complete the assembly of the bearing, improving labor efficiency and bearing assembly efficiency.

[0022] like Figures 1 to 9 As shown, the pressing rod 5 consists of a horizontal part and a vertical part, which together form an L-shaped pressing rod 5. The bending part of the pressing rod 5 is rounded. The vertical part of the pressing rod 5 passes through the limiting sleeve 4 and is slidably connected to it. The pressing assembly also includes a pressing block 6 fixedly connected to the outside of the pressing rod 5. The side of the pressing block 6 away from the pressing rod 5 is inclined. A return spring 7 is fixedly connected between the pressing block 6 and the limiting sleeve 4, and the return spring 7 is sleeved on the outside of the pressing rod 5. A movable extrusion ring 8 is slidably connected to the outside of the pressing block 6. The extrusion ring 8 has a guide groove 9 that matches the pressing block 6 inside. The extrusion ring 8 is slidably connected to the outside of the limiting sleeve 4. During operation, specifically, when adjustment of the pressure rod 5 is required, the compression ring 8 is first driven to slide on the surface of the limiting sleeve 4. The sliding of the compression ring 8 causes the guide groove 9 inside it to move together. (Refer to the attached document.) Figure 7As shown, since the contact surface between the pressing block 6 and the guide groove 9 is inclined, the guide groove 9 will push the pressing block 6 to slide together during the sliding process of the extrusion ring 8. During the sliding process, the pressing block 6 will squeeze the reset spring 7 to compress it and drive the pressing rod 5 to gather or disperse, thus achieving the effect of adaptive adjustment of the pressing rod 5.

[0023] like Figures 4 to 8 As shown, a rotating bearing 10 is fixedly connected to the side of the extrusion ring 8 near the sliding plate 3, and a rotating handle 11 is fixedly connected to the side of the rotating bearing 10 away from the extrusion ring 8. The surface of the limiting sleeve 4 near the sliding plate 3 is threaded, and the rotating handle 11 is connected to the limiting sleeve 4 by the thread. During operation, specifically, when the extrusion ring 8 needs to slide, the employee needs to manually hold the rotating handle 11 to rotate it. Since the rotating handle 11 is connected to the limiting sleeve 4 by a thread, the rotating handle 11 will slide while rotating. The rotation of the rotating handle 11 will drive the rotating bearing 10 to rotate, and the sliding of the rotating handle 11 will push the extrusion ring 8 to slide together, thereby achieving the effect of controllably driving the extrusion ring 8 to slide and translate left and right, and thus adjusting the pressure rod 5. It can be understood that the threaded connection has a certain self-locking function. After the rotating handle 11 stops rotating, the thread self-locking will prevent the pressure rod 5 from moving again, thus improving the stability of the equipment. It can also be understood that the connection method of the extrusion ring 8, rotating bearing 10, and rotating handle 11 is existing technology. For details, please refer to the connection method of shaft, bearing, and bearing seat, which will not be elaborated further.

[0024] like Figures 1 to 5 As shown, the drive motor 1 is externally fixedly connected to an installation plate 12, the sliding plate 3 and the bottom end of the installation plate 12 are slidably connected to a limit plate 13, the bottom surface of the limit plate 13 is fixedly connected to a lifting block 14, and the bottom end of the lifting block 14 is fixedly connected to a remote control vehicle body 15. During operation, considering the large number of workshops within the factory, when most rotating rollers malfunction, they are often replaced first before the bearings are replaced uniformly. This method requires employees to mark and collect the replaced rotating rollers before transporting them to the maintenance department for replacement, which wastes a lot of manpower and resources and is not very efficient. However, with this embodiment of the invention, employees only need to control the remote-controlled vehicle 15 to drive it to the corresponding workshop, and then control the lifting block 14 to rise and fall. The rising and falling of the lifting block 14 causes the limit plate 13 to rise and fall, which in turn causes the sliding plate 3 and the mounting plate 12 to rise and fall, thereby... Adjust the height of the limiting sleeve 4 until its axis height matches that of the rotating roller. Then, perform the bearing assembly or disassembly. This design eliminates the need for collecting and transporting the replaced rotating rollers; the bearing switching can be completed within the workshop, improving work efficiency and avoiding waste of human resources. It is understood that the lifting block 14 and the remote-controlled vehicle 15 are existing technologies. In specific implementations, the lifting block 14 can be a combination of a hydraulic cylinder and a mounting block, and the remote-controlled vehicle 15 can be an AGV (Automated Guided Vehicle). Further details are omitted. It should also be noted that, referring to the attached... Figure 2 , 3 As shown, the rotating rollers adapted in this embodiment of the invention are all equipped with rotating disks after being disassembled. After disassembly, the rotating disks can support the rotating rollers. Since the components on the rotating rollers are often quite heavy, there is no need to additionally limit the rotating rollers when assembling the bearings.

[0025] like Figures 1 to 6 As shown, a snap-fit ​​block 16 is fixedly connected to the side of the pressing rod 5 away from the limiting sleeve 4. The snap-fit ​​block 16 is designed in the shape of a right trapezoid, and multiple slots are opened on the inclined surface of the snap-fit ​​block 16. During operation, before assembling the bearings, the old bearings need to be disassembled. Traditionally, bearing disassembly is done by assembly personnel, meaning employees remove the old bearings before assembling the new ones. This part has always been a manual operation. However, with the embodiment of this invention, see attached... Figure 3As shown, firstly, by controlling multiple pressure rods 5 to converge, the locking blocks 16 are driven to converge. At this time, the remote control vehicle 15 moves, causing the locking blocks 16 to extend into the interior of the bearing 28 to be disassembled. Then, the pressure rods 5 disperse, causing the multiple locking blocks 16 to disperse until the inclined surface of the locking blocks 16 contacts the inner ring of the bearing 28 to be disassembled and presses and locks it. Then, the remote control vehicle 15 moves again and moves away from the bearing 28 to be disassembled. Thus, through the friction between the locking blocks 16 and the bearing 28 to be disassembled, the bearing 28 to be disassembled is pulled out from the interior of the bearing housing 27, thereby achieving the effect of automatic bearing disassembly. It can be understood that by opening a groove on the surface of the locking blocks 16, the friction between the locking blocks 16 and the bearing 28 to be disassembled can be effectively increased, thereby improving the stability of the device operation.

[0026] like Figures 6 to 11 As shown, a connecting sleeve 19 is provided inside the limiting sleeve 4 and on the side away from the pressing rod 5. The connecting sleeve 19 is fixedly connected to the transmission screw 2. A limiting component is provided inside the connecting sleeve 19. The limiting component is used to limit the positioning shaft when pressing the bearing, and to limit the pressing rod 5 when disassembling the bearing. The limiting component includes multiple sliding sleeves 20, which are slidably sleeved together and slidably connected inside the connecting sleeve 19. The telescopic ends of the multiple sliding sleeves 20 and the ends of the connecting sleeve 19 away from the transmission screw 2 are all chamfered, and the chamfer angles are matched. An electric telescopic rod 21 is fixedly connected between the innermost sliding sleeve 20 and the connecting sleeve 19. A rubber sleeve 22 is sleeved on the outside of the pressing rod 5. When working, refer to the appendix Figure 10 As shown, during the assembly stage of the bearing to be installed 26, the electric telescopic rod 21 is in a retracted state, and multiple sliding sleeves 20 are retracted inside the connecting sleeve 19. Simultaneously, the multiple sliding sleeves 20 and the connecting sleeve 19 exhibit an inwardly contracting stepped shape. In practice, the dimensions of the sliding sleeves 20 are adjusted so that the stepped aperture when retracted matches the positioning shafts of different sizes. Thus, during installation, simply inserting the positioning shaft into the corresponding sliding sleeve 20 completes the positioning operation, achieving a rapid positioning effect. This facilitates subsequent bearing installation and improves installation efficiency. (Refer to Appendix) Figure 11As shown, during the disassembly of the bearing 28 to be disassembled, the electric telescopic rod 21 is in an extended state, and multiple sliding sleeves 20 are pushed out from inside the connecting sleeve 19 and cooperate to form a boss. At this time, by pushing the connecting sleeve 19, this boss can be pushed towards the pressing rod 5 until it contacts the rubber sleeve 22 on the surface of the pressing rod 5. The boss applies a compressive force to the pressing rod 5, thereby limiting the pressing rod 5 and preventing the pressing rod 5 from loosening during the disassembly process, which would cause the pressing block 6 to separate from the bearing 28 to be disassembled. This improves the stability and quality of the disassembly work. It can be understood that, referring to the attached... Figure 7 As shown, the outer side of the sliding sleeve 20 is fixed with a sliding groove. Except for the inner side of the sliding sleeve 20, the sliding sleeve 20 and the connecting sleeve 19 are all provided with a sliding groove that matches the slip ring.

[0027] like Figure 5 As shown, the bottom ends of the sliding plate 3 and the mounting plate 12 are both fixedly connected to multiple hydraulic rods 17, and the output ends of the hydraulic rods 17 are fixedly connected to fastening rods 18. The surface of the remote control vehicle body 15 is provided with multiple slots that are compatible with the fastening rods 18. During operation, in the initial state, the hydraulic rod 17 at the bottom of the mounting plate 12 is extended, pushing the fastening rod 18 into the slot on the surface of the remote control vehicle body 15, thus limiting the mounting plate 12 to prevent it from moving. The hydraulic rod 17 at the bottom of the sliding plate 3 is retracted, so that the sliding plate 3 can slide normally without being affected while the drive motor 1 drives the transmission screw 2 to rotate, which facilitates the installation of the bearing 26 to be installed. When the bearing 28 to be removed is being removed, the hydraulic rod 17 at the bottom of the sliding plate 3 extends, pushing the fastening rod 18 into the slot on the surface of the remote control vehicle body 15. The hydraulic rod 17 at the bottom of the mounting plate 12 retracts, causing the fastening rod 18 to separate from the slot. When the drive motor 1 is restarted, the sliding plate 3 remains stationary, while the mounting plate 12 drives the drive motor. 1. Sliding is performed so that, while keeping the position of the extrusion ring 8 unchanged, the transmission screw 2 pushes the connecting sleeve 19 to slide inside the limiting sleeve 4. This is because, during the disassembly process, it is also necessary to pay attention to the position of the extrusion ring 8 and the remote control vehicle body 15. If, during the movement of the connecting sleeve 19, the sliding plate 3 slides towards the drive motor 1, the extrusion ring 8 will retract towards the remote control vehicle body 15. This will cause the space between the extrusion ring 8 and the remote control vehicle body 15 to become smaller. When disassembling some rotating rollers, an excessively short extrusion ring 8 will cause interference between the remote control vehicle body 15 and the turntable on the rotating roller, making it impossible to disassemble smoothly. However, in the embodiment of the present invention, the alternating sliding of the sliding plate 3 and the mounting plate 12 adapts to different disassembly and installation situations, thereby improving the applicability of the equipment.

[0028] like Figures 10 to 11As shown, a laser emitter 23 is fixedly connected to the innermost surface of the sliding sleeve 20, and the center of the laser emitter 23 and the center of the sliding sleeve 20 are on the same axis. During operation, by setting the rubber sleeve 22, when the position of the limiting sleeve 4 is adjusted by remotely controlling the vehicle body 15 and the lifting block 14, the laser emitter 23 is activated to emit a laser beam. The laser beam can effectively assist the employees in positioning the bearing seat 27, saving positioning time and improving efficiency.

[0029] like Figures 1 to 7 As shown, a telescopic ring 24 is fixedly connected to the side of the extrusion ring 8 away from the rotating bearing 10, and a limit ring 25 is fixedly connected to the side of the telescopic ring 24 away from the extrusion ring 8. During operation, considering the installation depth of the bearing 26 to be installed, it is necessary to avoid over- or under-installation. Therefore, a telescopic ring 24 and a limiting ring 25 are designed. As the compression ring 8 slides, it simultaneously drives the telescopic ring 24 and the limiting ring 25 to slide together. By adjusting the thickness of the telescopic ring 24, for bearings 26 of different sizes, after the compression ring 8 stops sliding, the distance between the limiting ring 25 and the top of the locking block 16 is always the installation depth of the bearing. Furthermore, the size of the limiting ring 25 is set to match the size of the bearing housing 27. When the limiting ring 25 contacts the bearing housing 27, the sliding plate 3 can no longer slide, and the bearing is perfectly installed, thus achieving an automatic limiting effect and ensuring installation quality.
