Description

Technical Field

[0001] This invention relates to the field of manufacturing technology, specifically to a wheel hub bearing oil seal press-fitting device and method based on rapid detection. Background Technology

[0002] During the assembly process of wheel hub bearings, it is usually necessary to press the oil seal into the predetermined installation position of the wheel hub bearing. Existing wheel hub bearing oil seal pressing devices generally use a cylinder or other driving component to drive the press head downward, so that the press head applies pressure to the oil seal and presses the oil seal into the wheel hub bearing.

[0003] However, during the pressing process, the bottom wall of the press head will form a large area of ​​tight contact with the top wall of the oil seal. After pressing, the press head and the oil seal are prone to local negative pressure due to the difficulty of air entering between the contact surfaces. At the same time, the adhesion of the lubricating grease and rubber materials on the surface of the oil seal, as well as the adhesion effect caused by the pressing pressure, will further enhance the adsorption and adhesion between the press head and the oil seal.

[0004] Therefore, when the pressure head is reset upwards after pressing, it is easy for the pressure head to move the oil seal that has already been pressed into place upwards or cause a positional shift, resulting in a change in the oil seal installation position, affecting the assembly accuracy and sealing effect of the oil seal. In severe cases, it may even cause the oil seal to tilt, loosen, or even need to be repressed, thereby reducing the quality and processing efficiency of wheel hub bearing oil seal pressing.

The transmission cavity is connected to two or more separation mechanisms, including a blocking mechanism and a blowing mechanism. A displacement sensor is connected to the pressure head.

[0006] Optionally, the drive mechanism includes a fixed gear ring, a motor, and a movable gear ring. The fixed gear ring is fixedly connected to the connecting seat and surrounds the pressure head. The motor is fixedly connected to the motor base, and the motor base is slidably connected to the inner wall of the transmission cavity. A drive gear is fixedly connected to the motor output shaft. The movable gear ring is rotatably connected to the inner wall of the transmission cavity. The outer wall of the movable gear ring has external teeth, and the inner wall of the movable gear ring has internal teeth. The drive gear and the external teeth of the movable gear ring mesh. The blocking mechanism includes a driven gear, a permanent magnet, a nut, a threaded rod, and a sliding column. The driven gear is fixed to the threaded rod and meshes with the internal teeth on the driven gear and the movable gear ring. The threaded rod and the nut are threaded together, and the nut is fixed to the inner wall of the transmission cavity. The permanent magnet is fixed to the driven gear, and the sliding column is fixed to the threaded rod.

[0007] Optionally, the blowing mechanism includes an airbag ball, a hose, an air guide strip, and an iron plate. The airbag ball is fixed to the inner wall of the transmission cavity. The airbag ball is connected to the air guide strip through the hose. The air guide strip is slidably connected to the inner wall of the transmission cavity. The air guide strip has an air guide channel that communicates with the bottom wall of the air guide strip. The iron plate is fixed to the air guide strip. The air guide strip is connected to the inner wall of the transmission cavity through an elastic element. Two or more curved blocks are fixed to the movable toothed ring.

[0008] Optionally, the bottom wall of the motor base is connected to two or more ball bearings in a rolling manner.

[0009] Optionally, a processor is connected to the support.

[0010] Optionally, a pressure sensor is connected to the pressure head.

[0011] Optionally, the motor base is L-shaped, and the ball bearings are rotatably connected to the bottom wall of the vertical section of the motor base.

[0012] Optionally, a slide rail is fixedly connected to the inner wall of the transmission cavity, and the motor base is slidably connected to the slide rail.

[0013] Optionally, the bottom wall of the support is connected with anti-slip components.

[0014] A method for press-fitting wheel hub bearing oil seals based on rapid detection, and based on the aforementioned wheel hub bearing oil seal press-fitting device based on rapid detection, includes the following steps: Step 1: Install the wheel hub bearing onto the support and place the oil seal on the wheel hub bearing; Step 2: Control the piston rod on the cylinder to extend, so that the pressure head moves down and presses the oil seal into the wheel hub bearing; Step 3: Use the drive mechanism to control the blocking mechanism to unblock the ventilation channel, control the air blowing mechanism to blow air into the ventilation channel, and then use the drive mechanism to rotate the pressure head to prevent the pressure head and oil seal from sticking together. Step 4: Control the piston rod on the cylinder to shorten, and remove the wheel hub bearing with the oil seal installed.

[0015] The present invention has the following beneficial effects: This invention uses a single driving mechanism to sequentially control the sliding column to exit the ventilation channel, the air guide strip to connect with the ventilation channel and cooperate with the airbag ball to blow air, and drive the pressure head to rotate relative to the connecting seat. First, it weakens the adsorption and adhesion by reducing the contact area between the pressure head and the oil seal. Then, it destroys the negative pressure adsorption state by blowing air into the contact interface between the two. Finally, it further destroys the adhesion interface by utilizing the relative rotation between the pressure head and the oil seal. Since the first two anti-adhesion effects have reduced the adhesion force between the two, it is not easy for the oil seal to rotate when the pressure head rotates, thus forming a multi-layered continuous anti-adhesion effect. This reduces the possibility of displacement of the oil seal during the upward movement of the pressure head and improves the positional stability of the oil seal after press-fitting. At the same time, it does not require the separate setting of multiple independent driving mechanisms, and the structure has a high degree of linkage, which is conducive to improving the stability and processing efficiency of wheel hub bearing oil seal press-fitting.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0021] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] This invention is primarily used in the wheel hub bearing manufacturing industry. During wheel hub bearing manufacturing, it is necessary to press-fit the oil seal into the wheel hub bearing; this invention can achieve this.

[0023] like Figures 2-9 As shown, a wheel hub bearing oil seal press-fitting device based on rapid detection includes a support 1, a cylinder 2 fixedly connected to the support 1, a connecting seat 4 fixedly connected to the piston rod of the cylinder 2, the connecting seat 4 being slidably connected to the support 1, a pressure head 3 being rotatably connected to the connecting seat 4, and a drive mechanism being connected to the connecting seat 4. The cylinder 2 drives the connecting seat 4 to move up and down along the support 1, thereby driving the pressure head 3 to move up and down, so as to realize the pressing of the wheel hub bearing oil seal and the reset after pressing. At the same time, the connecting seat 4 provides a rotating mounting base for the pressure head 3, so that the pressure head 3 can rotate relative to the connecting seat 4 under the action of the driving mechanism.

[0024] The pressure head 3 has a transmission cavity 31, which is connected to the outer wall of the pressure head 3 through two or more ventilation channels 32. The transmission cavity 31 is connected to two or more separation mechanisms, including a blocking mechanism and a blowing mechanism. The pressure head 3 is connected to a displacement sensor.

[0025] The transmission cavity 31 is used to accommodate the drive mechanism and the separation mechanism. The ventilation channel 32 is used to be blocked by the blocking mechanism during pressing and to form a channel for air to enter between the bottom wall of the press head 3 and the top wall of the oil seal after pressing. The separation mechanism is used to release the adsorption and adhesion between the press head 3 and the oil seal after pressing. The displacement sensor is used to quickly detect the movement position of the press head 3 so as to determine the pressing stroke and pressing position of the press head 3.

[0026] Based on the aforementioned scheme, the drive mechanism is further configured as follows: the drive mechanism includes a fixed gear ring 20, a motor 21, and a movable gear ring 6. The fixed gear ring 20 is fixedly connected to the connecting seat 4 and is arranged around the pressure head 3. The motor 21 is fixedly connected to the motor seat 18, and the motor seat 18 is slidably connected to the inner wall of the transmission cavity 31. A drive gear 5 is fixedly connected to the output shaft of the motor 21. The movable gear ring 6 is rotatably connected to the inner wall of the transmission cavity 31. The outer wall of the movable gear ring 6 is provided with external teeth, and the inner wall of the movable gear ring 6 is provided with internal teeth. The drive gear 5 and the external teeth of the movable gear ring 6 mesh. The motor 21 is used to drive the drive gear 5 to rotate. The drive gear 5 drives the movable gear ring 6 to rotate by meshing with the outer teeth of the movable gear ring 6, thereby providing synchronous driving force for multiple separation mechanisms. When the motor base 18 drives the drive gear 5 to move up and mesh with the fixed gear ring 20, the meshing action between the fixed gear ring 20 and the drive gear 5 can be used to drive the pressure head 3 to rotate relative to the connecting seat 4, so as to help release the adhesion between the pressure head 3 and the oil seal.

[0027] The blocking mechanism includes a driven gear 8, a permanent magnet 9, a nut 10, a threaded rod 11, and a sliding column 12. The driven gear 8 is fixed to the threaded rod 11, and the driven gear 8 meshes with the internal teeth on the movable gear ring 6. The threaded rod 11 and the nut 10 are threaded together, and the nut 10 is fixed to the inner wall of the transmission cavity 31. The permanent magnet 9 is fixed to the driven gear 8, and the sliding column 12 is fixed to the threaded rod 11.

[0028] When the movable gear ring 6 rotates, it drives the driven gear 8 to rotate through the internal teeth. The driven gear 8 drives the threaded rod 11 to rotate. The threaded engagement between the threaded rod 11 and the nut 10 enables the driven gear 8, the permanent magnet block 9, and the slide column 12 to rise and fall synchronously. During pressing, the slide column 12 blocks the ventilation channel 32 to ensure that the bottom wall of the pressure head 3 has a large effective pressing contact area. After pressing, the slide column 12 moves upward and exits the ventilation channel 32, thereby reducing the contact area between the pressure head 3 and the oil seal and providing a passage for subsequent air blowing separation.

[0029] Based on the aforementioned scheme, the air blowing mechanism is further configured as follows: the air blowing mechanism includes an airbag ball 13, a hose 14, an air guide strip 15, and an iron plate 16. The airbag ball 13 is fixed to the inner wall of the transmission cavity 31. The airbag ball 13 is connected to the air guide strip 15 through the hose 14. The air guide channel in the hose 14 and the air guide strip 15 is connected. The air guide strip 15 is slidably connected to the inner wall of the transmission cavity 31. The air guide strip 15 has an air guide channel that communicates with the bottom wall of the air guide strip 15. The iron plate 16 is fixed to the air guide strip 15. The air guide strip 15 is connected to the inner wall of the transmission cavity 31 through an elastic element 17. Two or more curved blocks 7 are fixed to the movable toothed ring 6.

[0030] When the permanent magnet 9 moves upward to the side of the iron plate 16 along with the blocking mechanism, the permanent magnet 9 attracts the iron plate 16, causing the air guide strip 15 to overcome the elastic force of the elastic element 17 and move towards the ventilation channel 32, and connecting the air guide channel in the air guide strip 15 with the ventilation channel 32; at the same time, the movable toothed ring 6 drives the curved block 7 to rotate and squeeze the airbag ball 13, so that the air in the airbag ball 13 is sprayed into the space between the bottom wall of the pressure head 3 and the top wall of the oil seal through the hose 14, the air guide strip 15 and the ventilation channel 32 in sequence, thereby breaking the negative pressure adsorption state between the two and promoting the separation of the pressure head 3 and the oil seal.

[0031] In a preferred embodiment, the bottom wall of the motor base 18 is connected by two or more rolling balls 19. The rolling balls 19 are used to reduce the frictional resistance between the motor base 18 and the permanent magnet block 9, which helps to reduce wear between the motor base 18 and adjacent structures.

[0032] A processor is connected to the support 1. The processor is used to receive detection signals from detection elements such as displacement sensors and pressure sensors, and to control the working status of cylinder 2 and motor 21 according to the detection results, so as to realize intelligent control of the pressing process.

[0033] A pressure sensor is connected to the pressure head 3. The pressure sensor is used to detect the pressing pressure applied by the pressure head 3 to the oil seal, thereby helping to determine whether the oil seal is properly pressed in and avoiding damage to the oil seal or wheel hub bearing caused by excessive pressing pressure.

[0034] The motor base 18 is L-shaped, and the ball bearing 19 is rotatably connected to the bottom wall of the vertical section of the motor base 18.

[0035] A slide rail is fixedly connected to the inner wall of the transmission cavity 31, and the motor base 18 is slidably connected to the slide rail. The slide rail is used to guide and limit the movement direction of the motor base 18, so that the motor base 18 can rise and fall stably in a predetermined direction, and avoid deviation during the movement of the motor base 18, thereby ensuring that the drive gear 5 can accurately mesh with the movable gear ring 6 and the fixed gear ring 20.

[0036] Optionally, the bottom wall of support 1 is connected to an anti-slip component. The anti-slip component is used to increase the friction between support 1 and the external support, reduce the sliding or shaking of the device due to force during the oil seal pressing process, and improve the stability of the entire pressing device during operation.

[0037] like Figure 1 As shown, a method for press-fitting wheel hub bearing oil seals based on rapid detection, and based on the aforementioned wheel hub bearing oil seal press-fitting device based on rapid detection, includes the following steps: Step 1: Install the wheel hub bearing onto support 1, and place the oil seal on the wheel hub bearing; Step 2: Control the piston rod on cylinder 2 to extend, so that the pressure head 3 moves down to press the oil seal into the wheel hub bearing; Step 3: Use the drive mechanism to control the blocking mechanism to unblock the ventilation channel 32, control the air blowing mechanism to blow air into the ventilation channel 32, and then use the drive mechanism to rotate the pressure head 3 to prevent the pressure head 3 from sticking to the oil seal. Step 4: Control the piston rod on cylinder 2 to shorten, and remove the wheel hub bearing with the oil seal installed.

[0038] Implementation process: In the initial state, the lower end of the slide column 12 is flush with the lower end of the ventilation channel 32, increasing the contact area between the pressure head 3 and the oil seal. The horizontal section of the air guide strip 15 is located on the side of the ventilation channel 32 to prevent obstruction of the movement of the threaded rod 11. The iron plate 16 is higher than the permanent magnet block 9, the fixed gear ring 20 is higher than the drive gear 5, the fixed gear ring 20 does not mesh with the drive gear 5, and the motor base 18 is located at the lower limit position.

[0039] When the oil seal needs to be press-fitted, the hub bearing is installed on the support 1, and the oil seal is placed between the inner and outer rings of the top wall of the hub bearing.

[0040] A mounting groove can be provided on the support 1, and a clamping mechanism can be provided in the mounting groove. The wheel hub bearing is located in the mounting groove for limiting, and the clamping mechanism clamps and positions the wheel hub bearing.

[0041] When cylinder 2 is activated, the piston rod on cylinder 2 extends, thereby driving the connecting seat 4 and the pressure head 3 to move down. The pressure head 3 presses the oil seal between the inner and outer rings of the top wall of the wheel hub bearing.

[0042] After the oil seal is pressed into place, the top wall of the oil seal will stick to the bottom wall of the pressure head 3. At this time, the motor 21 is started. The motor 21 drives the drive gear 5 to rotate, the drive gear 5 drives the movable gear ring 6 to rotate, and the movable gear ring 6 drives all the driven gears 8, threaded rod 11, and sliding column 12 to rotate. Since the threaded rod 11 and the nut 10 are threadedly connected, when the threaded rod 11 rotates, it will move upward together with the driven gear 8, permanent magnet block 9, and sliding column 12. The sliding column 12 moves upward and disengages from the ventilation channel 32, reducing the contact area between the bottom wall of the pressure head 3 and the top wall of the oil seal, thus achieving the first layer of anti-sticking effect.

[0043] When the permanent magnet 9 moves upward to the side of the iron sheet 16, the permanent magnet 9 magnetically attracts the iron sheet 16, and the air guide strip 15 overcomes the elastic force of the elastic element 17 and moves towards the air passage 32. The air outlet of the air guide channel on the air guide strip 15 (such as...) Figure 9 (As shown on the bottom wall of the air guide strip 15) is aligned with the ventilation channel 32. When the movable toothed ring 6 rotates, it will compress the airbag ball 13 through the curved block 7. The air in the airbag ball 13 will be ejected from the air outlet of the air guide strip 15 into the ventilation channel 32 through the hose 14, so that the air enters between the bottom wall of the pressure head 3 and the top wall of the oil seal, achieving a second layer of anti-adhesion effect.

[0044] After one of the permanent magnet blocks 9 moves up to a certain height, it abuts against the ball bearing 19 on the motor base 18. The permanent magnet block 9 supports the ball bearing 19, the motor base 18, the motor 21, and the drive gear 5. The drive gear 5 moves up to mesh with the fixed gear ring 20 (at this time, the drive gear 5 still maintains meshing with the movable gear ring 6). Driven by the drive gear 5, the pressure head 3 rotates on the connecting seat 4. After the pressure head 3 rotates, it will greatly release the adhesion between itself and the oil seal, and will not drive the oil seal to move, thus achieving a third layer of anti-adhesion effect.

[0045] Then, the piston rod on the control cylinder 2 is shortened, the pressure head 3 moves upward to disengage from the oil seal, and the clamping mechanism releases the clamping of the wheel hub bearing, so that the wheel hub bearing can be taken out and the press-fitting is completed.

[0046] The components inside the pressure head 3 are then reset by reversing the motor 21. The reset principle is known from the above, and will not be described again here.

[0047] The beneficial effects of this invention are: This invention uses cylinder 2 to drive connecting seat 4 and pressure head 3 to move downwards, so that pressure head 3 presses the oil seal between the inner and outer rings of the top wall of the wheel hub bearing, thus completing the pressing of the oil seal. After pressing, motor 21 drives drive gear 5 to rotate, drive gear 5 to drive movable gear ring 6 to rotate, and movable gear ring 6 further drives driven gear 8, threaded rod 11 and sliding column 12 to move. The threaded engagement between threaded rod 11 and nut 10 causes sliding column 12 to move upwards and disengage from ventilation channel 32, thereby reducing the contact area between the bottom wall of pressure head 3 and the top wall of oil seal, weakening the adsorption and adhesion between the two, and achieving the first layer of anti-adhesion effect.

[0048] During the upward movement of the sliding column 12, the permanent magnet block 9 is simultaneously moved upward. When the permanent magnet block 9 moves to the side of the iron plate 16, the permanent magnet block 9 attracts the iron plate 16 through magnetic force, causing the air guide strip 15 to overcome the elastic force of the elastic element 17 and move towards the ventilation channel 32, so that the air guide channel in the air guide strip 15 is connected to the ventilation channel 32. At the same time, when the movable toothed ring 6 rotates, it drives the curved block 7 to periodically squeeze the airbag ball 13, so that the air in the airbag ball 13 enters between the bottom wall of the pressure head 3 and the top wall of the oil seal through the hose 14, the air guide strip 15 and the ventilation channel 32, thereby breaking the negative pressure adsorption state formed between the two and blowing air to separate the contact interface, thus achieving a second anti-adhesion effect.

[0049] After the permanent magnet block 9 continues to move upward, it can further drive the motor base 18, motor 21 and drive gear 5 to move upward, so that the drive gear 5 can maintain engagement with the movable gear ring 6 and engage with the fixed gear ring 20 at the same time. Since the fixed gear ring 20 is fixed to the connecting seat 4, the drive gear 5 can further drive the pressure head 3 to rotate relative to the connecting seat 4 when it rotates. The relative rotation between the pressure head 3 and the oil seal further destroys the adhesion interface between the two. Due to the first two anti-adhesion effects, the rotation of the pressure head 3 will not drive the oil seal to rotate, realizing the third anti-adhesion effect, reducing the possibility of displacement of the oil seal when the pressure head 3 moves upward, thereby improving the positional stability of the oil seal after pressing.

[0050] This invention utilizes the same motor 21 and the same gear transmission structure to sequentially achieve multiple actions, such as the sliding column 12 exiting the ventilation channel 32, the air guide strip 15 connecting with the ventilation channel 32 and cooperating with the airbag ball 13 to blow air, and the pressure head 3 rotating. This allows the three anti-adhesion methods of reducing contact area, blowing air to relieve pressure, and relative rotation to form a continuous coordination, eliminating the need for multiple independent drive mechanisms and resulting in high structural linkage. After separation, the pressure head 3 can be moved upward by controlling the cylinder 2 to detach from the oil seal. Subsequently, only reversing the motor 21 is needed to reset the internal components of the pressure head 3, which is beneficial for continuous pressing operations and improves the stability and processing efficiency of wheel hub bearing oil seal pressing.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
