Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sealing ring press-fitting equipment, in particular to an automatic press-fitting equipment for sealing rings of automobile wheel hub bearings. BACKGROUND

[0002] Wheel hub bearings are core components of automobile load and movement, and the sealing performance thereof is crucial to the service life and driving safety of the bearings. Press-fitting of sealing rings is a key process in the assembly of wheel hub bearing assemblies. The traditional manual press-fitting method is not only inefficient and labor-intensive, but also difficult to ensure the uniformity and consistency of press-fitting force and position, which can easily lead to quality problems such as tilting, damage or misplacement of the sealing ring.

[0003] To improve the automation level, some semi-automatic or fully-automatic press-fitting equipment has appeared in the prior art. These devices usually use linear feeding mechanisms such as vibration discs and conveyer belts to transport sealing rings and wheel hub bearings respectively, and then use mechanical hands or cylinder-driven press heads to complete the picking and placing and press-fitting actions. However, such devices have the following significant defects:

[0004] 1. Independent linear feeding and multiple actuators are used, which occupies a large area and has a waiting time between actions, making it difficult to further improve the beat and unable to meet the needs of high-efficiency and large-scale production;

[0005] 2. Multiple motors, cylinders and sensors are used to coordinate actions, which requires a complex electrical control system for synchronization and coordination, increasing the device failure rate and maintenance difficulty. SUMMARY

[0006] In view of the above deficiencies in the prior art, the present application aims to provide an automatic press-fitting equipment that can speed up the press-fitting efficiency of sealing rings and has a low device failure rate.

[0007] The technical solution adopted by the present application to achieve the above-mentioned purpose is as follows: an automatic press-fitting equipment for sealing rings of automobile wheel hub bearings, comprising a rotary feeding mechanism A, a rotary feeding mechanism B, a rotary reversing mechanism and a press-fitting mechanism, the rotary feeding mechanism A is used to supply sealing rings, the rotary feeding mechanism A comprises a feeding disc A and a one-way drive component A cooperating with the feeding disc A;

[0008] The rotary feeding mechanism B is used to supply wheel hub bearings, and the rotary feeding mechanism B comprises a feeding disc B and a one-way drive component B cooperating with the feeding disc B;

[0009] The rotary feeding mechanism B and the rotary feeding mechanism A are provided with the rotary reversing mechanism therebetween, the rotary reversing mechanism comprises a driving device and a rotary main shaft power-connected with the driving device, and the press-fitting mechanism is fixedly connected to the rotary main shaft.

[0010] The rotating spindle is poweredly connected to both the unidirectional drive component A and the unidirectional drive component B. Under the action of the unidirectional drive component A and the unidirectional drive component B, the rotating spindle can drive the feeding disc A and the feeding disc B to rotate only in one direction.

[0011] In the above technical solution, in order to realize the placement of the sealing ring, multiple sets of positioning components A are fixedly connected in a ring array on the feeding tray A. The sealing ring is placed on the positioning component A, and the top surface of the sealing ring protrudes from the positioning component A.

[0012] Similarly, in order to place the wheel hub bearings, multiple sets of positioning components B are fixedly connected in a circular array on the feeding tray B. Wheel hub bearings are placed on the positioning components B, with the pressing surface of the wheel hub bearings facing upwards.

[0013] Furthermore, the aforementioned positioning component A adopts the following structure:

[0014] The positioning component A includes a placement platform with a placement groove on the placement platform, and a sealing ring is placed in the placement groove.

[0015] Furthermore, the aforementioned positioning component B adopts the following structure:

[0016] The positioning component B includes a base platform and a positioning pin fixedly connected to the base platform. The wheel hub bearing is placed on the base platform, and the positioning pin limits the position of the wheel hub bearing.

[0017] The placement platform is detachably and fixedly connected to the feeding tray A, and the base platform is detachably and fixedly connected to the feeding tray B.

[0018] In the above technical solution, the structures of the unidirectional drive component A and the unidirectional drive component B are as follows:

[0019] The unidirectional drive component A includes a stabilizing platform, a drive shaft, a ratchet, a pawl, an elastic element, a ratchet disc, and a drive disc. The drive disc is rotatably connected to the stabilizing platform, and the feed disc A is fixedly connected to the top of the drive disc. The drive disc has a drive cavity inside, and the ratchet disc is fixedly connected inside the drive cavity. The ratchet disc has a ratchet chamber, and multiple sets of pawls are rotatably connected to the ratchet disc within the ratchet chamber. Each set of pawls is provided with an elastic element inside the ratchet chamber.

[0020] The drive shaft is rotatably connected to the stabilizing machine base. The top end of the drive shaft passes through the drive disc and is located in the ratchet cavity. The ratchet wheel is fixedly connected to the top end of the drive disc. The pawl cooperates with the ratchet wheel. The rotating spindle is poweredly connected to the drive shaft.

[0021] The structure of the unidirectional drive component B is the same as that of the unidirectional drive component A, and the feed tray B is fixedly connected to the drive disk of the unidirectional drive component B.

[0022] Furthermore, to ensure stable driving force, the aforementioned stable machine platform includes a base, a connecting frame, and a rotating ring platform. The connecting frame is fixedly connected to the base, and the rotating ring platform is fixedly connected to the connecting frame. The bottom end of the drive shaft is rotatably connected to the base, and the drive disc is rotatably connected to the rotating ring platform.

[0023] In one embodiment, the ratchet and pawl in the one-way drive component B are oriented opposite to those in the one-way drive component A;

[0024] When the above structure is adopted, when the driving device drives the pressing mechanism to rotate in accordance with the feeding plate A, the feeding plate A rotates and the feeding plate B does not rotate; when the driving device drives the pressing mechanism to rotate in accordance with the feeding plate B, the feeding plate B rotates and the feeding plate A does not rotate.

[0025] In the above technical solution, the power connection between the unidirectional drive component A, the unidirectional drive component B and the rotating spindle adopts the following structure:

[0026] A drive gear A is fixedly connected to the rotating main shaft of both the unidirectional drive component A and the unidirectional drive component B. A relay gear is rotatably connected between the drive gear A and the drive gear B on the stabilizing machine platform. The drive gear A and the drive gear B are meshed with the relay gear.

[0027] In the above technical solution, the pressing mechanism adopts the following structure:

[0028] The pressing mechanism includes a vacuum adsorption head, a lifting motion module, and a vacuum system. The lifting motion module is fixedly connected to the rotating main shaft. The lifting motion module includes a lifting platform capable of linear lifting motion. The vacuum adsorption head is fixedly connected to the lifting platform. The vacuum system is provided on the rotating main shaft and cooperates with the vacuum adsorption head.

[0029] After the driving device drives the pressing mechanism to rotate, the vacuum suction head can correspond to the sealing ring on the feeding tray A or the part of the wheel hub bearing on the feeding tray B to be pressed.

[0030] In the above technical solution, the structure of the lifting motion module is as follows:

[0031] The lifting motion module also includes a module platform, a sliding column, a lead screw, and a drive motor. The module platform is fixedly connected to the rotating main shaft, the sliding column is fixedly connected to the module platform, the lifting platform is slidably connected to the sliding column, the lead screw is threadedly connected to the lifting platform, and the drive motor is fixedly connected to the module platform. The drive motor is poweredly connected to the lead screw.

[0032] A mounting platform is fixedly connected to the module platform, and the vacuum system is provided on the mounting platform.

[0033] Further optimized, the vacuum system includes a vacuum breaker valve, which is fixedly connected to the lifting platform. The vacuum breaker valve includes a valve shaft for driving the valve body to reverse direction. A rotating gear is fixedly connected to the valve shaft. A drive rack is fixedly connected to the module platform. When the lifting platform drives the vacuum adsorption head to descend and abuts against the position to be pressed into the hub bearing, and continues to descend, the drive rack drives the rotating gear to rotate, and the vacuum breaker valve disrupts the vacuum environment of the vacuum adsorption head.

[0034] The beneficial effects of this invention are:

[0035] 1. The equipment integrates the sealing ring feeding (rotary feeding mechanism A), wheel hub bearing feeding (rotary feeding mechanism B), rotation reversing and pressing mechanism into one system. The drive device drives the rotation of the main shaft, so that the pressing mechanism alternates between stations A and B (taking sealing rings - pressing), forming a continuous production cycle. It realizes full automation from feeding to pressing, reduces intermediate material handling and manual intervention, stabilizes the cycle time, and significantly improves production efficiency.

[0036] 2. Rotary feeding mechanism A is equipped with a one-way drive component A, and rotary feeding mechanism B is equipped with a one-way drive component B. Through the one-way drive components A and B, the rotary feeding mechanisms A and B can only perform unidirectional and intermittent rotary feeding. This design does not require additional electrical control signals or sensors to control the start and stop of the two feeding discs separately. It achieves perfect synchronization and interlocking with the rotational motion of the main shaft through a purely mechanical structure. The structure is ingenious, highly reliable, low in cost, and has a low failure rate.

[0037] 3. The sealing rings are positioned on the feeding tray A using positioning component A, and the wheel hub bearings are positioned on the feeding tray B using positioning component B. This structure is more stable than existing electrical components (such as electrical clamps), reducing the equipment failure rate. Compared with existing mechanical components (such as manual clamps), it reduces operation and speeds up the feeding process. Furthermore, both positioning components are detachably fixed to the feeding trays. This design greatly enhances the flexibility of the equipment, allowing for quick production changes when producing different models of wheel hub bearings and sealing rings. This saves adjustment time and expands the application range of the equipment.

[0038] 4. The pressing mechanism uses a vacuum suction head to grip the sealing ring. This is a non-contact, non-destructive material handling method, which is very suitable for easily deformable rubber sealing rings. It avoids scratches or deformation that may be caused by mechanical clamping. In addition, the lifting motion module uses a lead screw module, which provides precise and controllable pressing stroke and pressure. This ensures that each sealing ring is pressed to a consistent depth and position, guaranteeing the stability of product quality.

[0039] 5. Once the adsorption head has descended and is in place, a slight downward stroke will trigger the rack and pinion drive gear, opening the vacuum breaker valve. This ensures the sealing ring is reliably released and installed onto the bearing, preventing it from sticking to the adsorption head. The vacuum breaker valve's operation is triggered by the drive rack and pinion mechanism, eliminating the need for sensors and electrical control signals. It mechanically senses the physical signal of "in place" before releasing the vacuum, preventing premature release or overload damage to the workpiece before proper placement. This provides simple protection and reduces the number of electrical drive components, thus lowering the equipment failure rate. Attached Figure Description

Detailed Implementation

[0058] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0059] Please see Figure 1 , Figure 2 An automated pressing device for automotive wheel hub bearing seals includes a rotary feeding mechanism A100, a rotary feeding mechanism B200, a rotary reversing mechanism 300, and a pressing mechanism 400. First, please refer to... Figure 3 , Figure 4 The rotary feeding mechanism A100 is used to supply the sealing ring. Specifically, the rotary feeding mechanism A100 includes a feeding plate A101 and a one-way drive component A102 that cooperates with the feeding plate A101. Multiple sets of positioning components A103 are fixedly connected in a circular array on the feeding plate A101. The sealing ring is placed on the positioning component A103, and the top surface of the sealing ring protrudes from the positioning component A103. In this embodiment, the positioning component A103 includes a placement platform 1031, that is, the placement platform 1031 is provided with a placement groove 1032, and the sealing ring is placed in the placement groove 1032.

[0060] Secondly, please refer to Figure 5 , Figure 6 The rotary feeding mechanism B200 is used to supply wheel hub bearings. Specifically, the rotary feeding mechanism B200 includes a feeding disc B201 and a one-way drive component B202 that cooperates with the feeding disc B201. Multiple sets of positioning components B203 are fixedly connected in a circular array on the feeding disc B201. Wheel hub bearings are placed on the positioning components B203 with the pressing surface of the wheel hub bearing facing upward. In this embodiment, the positioning component B203 includes a base 2031 and a positioning pin 2032 fixedly connected to the base 2031. The wheel hub bearing is placed on the base 2031, and the positioning pin 2032 limits the wheel hub bearing. More specifically, in this embodiment, the positioning pin 2032 is inserted into the hole of the wheel hub bearing.

[0061] Furthermore, the aforementioned placement platform 1031 is detachably fixed to the feeding tray A101, and the base platform 2031 is detachably fixed to the feeding tray B201. In this way, when producing different models of wheel hub bearings and sealing rings, only the corresponding positioning module and feeding tray need to be replaced to quickly achieve production changeover, saving adjustment time and expanding the application range of the equipment.

[0062] Furthermore, both the aforementioned unidirectional drive component A102 and unidirectional drive component B202 are components that can only achieve unidirectional rotation. In this embodiment, please refer to... Figure 3 , Figure 7 , Figure 8The one-way drive component A102 includes a stabilizing platform 501, a drive shaft 502, a ratchet 503, a pawl 504, an elastic element 505, a ratchet disc 506, and a drive disc 507. Specifically, the drive disc 507 is rotatably connected to the stabilizing platform 501, and the top of the drive disc 507 is fixedly connected to the feed disc A101. The drive disc 507 has a drive cavity 508 inside, and the ratchet disc 506 is fixedly connected inside the drive cavity 508. The ratchet disc 506 has a ratchet cavity 509, and multiple sets of pawls 504 are rotatably connected to the ratchet disc 506 within the ratchet cavity 509. Each set of pawls 504 is provided with an elastic element 505 in the ratchet cavity 509. The elastic element 505 can be a torsion spring.

[0063] In addition, a drive shaft 502 is rotatably connected to the stable machine base 501. The top end of the drive shaft 502 passes through the drive disk 507 and is located in the ratchet cavity 509. A ratchet wheel 503 is fixedly connected to the top end of the drive disk 507. A pawl 504 cooperates with the ratchet wheel 503. When the drive shaft 502 rotates, the upper ratchet wheel 503 can rotate. When the ratchet wheel 503 can push the pawl 504, the drive disk 507 can rotate, which in turn makes the feed disk A101 rotate. When the ratchet wheel 503 cannot push the pawl 504, the pawl 504 rotates itself and is continuously restored to its original position by the elasticity of the elastic element 505. In this way, the drive disk 507 does not rotate, which also makes the feed disk A101 not rotate.

[0064] Furthermore, the aforementioned stable machine platform 501 includes a base 5011, a connecting frame 5012, and a rotating ring platform 5013. The connecting frame 5012 is fixedly connected to the base 5011, and the rotating ring platform 5013 is fixedly connected to the connecting frame 5012. The bottom end of the drive shaft 502 is rotatably connected to the base 5011, and the drive disk 507 is rotatably connected to the rotating ring platform 5013. This structure can ensure that the drive shaft 502 and the drive disk 507 are more stable when rotating.

[0065] Furthermore, in this embodiment, please refer to... Figure 5 , Figure 7 , Figure 8 The structure of the one-way drive component B202 is the same as that of the one-way drive component A102, while the feed plate B201 is fixedly connected to the drive plate 507 of the one-way drive component B202.

[0066] Furthermore, in this embodiment, please refer to... Figure 1 , Figure 2 as well as Figure 9A rotary reversing mechanism 300 is provided between the rotary feeding mechanism B200 and the rotary feeding mechanism A100. The rotary reversing mechanism 300 includes a drive device 301 and a rotary spindle 302 that is poweredly connected to the drive device 301. A pressing mechanism 400 is fixedly connected to the rotary spindle 302. In addition, the rotary spindle 302 is poweredly connected to the drive shaft 502 in the one-way drive component A102 and the one-way drive component B202. In this way, when the drive device 301 drives the rotary spindle 302 to rotate, the pressing mechanism 400 can rotate synchronously and can provide power to the one-way drive component A102 and the one-way drive component B202.

[0067] In this embodiment, please refer to Figure 3 , Figure 5 , Figure 9 And 12, Figure 13 The power connection between the one-way drive component A102, the one-way drive component B202 and the rotating spindle 302 adopts the following structure:

[0068] A drive gear A601 is fixedly connected to the rotating spindle 302 of both the unidirectional drive component A102 and the unidirectional drive component B202. A drive gear B602 is fixedly connected to the rotating spindle 302. A relay gear 603 is rotatably connected between the drive gear A601 and the drive gear B602 on the stable machine base 501. The drive gear A601 and the drive gear B602 are meshed with the relay gear 603.

[0069] Furthermore, in one embodiment, the ratchet 503 and pawl 504 in the one-way drive component B202 are oriented opposite to those in the one-way drive component A102. When the above structure is adopted, when the drive device 301 drives the pressing mechanism 400 to rotate in relation to the feeding tray A101, the feeding tray A101 rotates while the feeding tray B201 does not rotate. When the drive device 301 drives the pressing mechanism 400 to rotate in relation to the feeding tray B201, the feeding tray B201 rotates while the feeding tray A101 does not rotate.

[0070] When the pressing mechanism 400 turns to the feeding plate A101 to pick up the material, the direction of the driving force of the rotating spindle 302 is just enough to make the feeding plate A101 rotate. The feeding plate A101 rotates one station and sends the next sealing ring to the picking point.

[0071] When the pressing mechanism 400 finishes picking up the material, it turns to the feeding plate B201 for pressing. The reverse direction of the driving force of the rotating spindle 302 causes the feeding plate B201 to rotate. The feeding plate B201 rotates one station and sends the next wheel hub bearing to be pressed to the pressing point.

[0072] In addition to the above, in one embodiment two, the ratchet 503 and pawl 504 in the one-way drive component B202 are oriented in the same way as the one-way drive component A102. When the above structure is adopted, when the drive device 301 drives the pressing mechanism 400 to rotate in relation to the feeding tray, both the feeding tray A101 and the feeding tray B201 rotate. When the drive device 301 drives the pressing mechanism 400 to rotate in relation to the feeding tray B201, neither the feeding tray A101 nor the feeding tray B201 rotates.

[0073] When the pressing mechanism 400 rotates to the feeding plate A101 to pick up material, the direction of the driving force of the rotating spindle 302 is just enough to make the feeding plate A101 and the feeding plate B201 rotate. The feeding plate A101 rotates one station to send the next sealing ring to the picking point, and the feeding plate B201 rotates one station to send the next wheel hub bearing to be pressed to the pressing point.

[0074] When the pressing mechanism 400 finishes picking up the material and turns to press the feeding plate B201, the reverse direction of the driving force of the rotating spindle 302 prevents the feeding plate B201 and the feeding plate A101 from rotating, so as to achieve pressing.

[0075] In addition to the above, in one embodiment three, the ratchet 503 and pawl 504 in the one-way drive component B202 are oriented in the same way as the one-way drive component A102. When the above structure is adopted, when the drive device 301 drives the pressing mechanism 400 to rotate in relation to the feeding tray, neither the feeding tray A101 nor the feeding tray B201 rotates. When the drive device 301 drives the pressing mechanism 400 to rotate in relation to the feeding tray B201, both the feeding tray A101 and the feeding tray B201 rotate.

[0076] When the pressing mechanism 400 takes the sealing ring from the feeding plate A101, and then turns to press the feeding plate B201, the direction of the driving force of the rotating spindle 302 is just enough to make the feeding plate A101 and the feeding plate B201 rotate. The feeding plate A101 rotates one station to send the next sealing ring to the picking point, and the feeding plate B201 rotates one station to send the next wheel hub bearing to be pressed to the pressing point.

[0077] When the pressing mechanism 400 completes the material taking and turns to feed the material on the feeding plate A101, the reverse direction of the driving force of the rotating spindle 302 prevents the feeding plate B201 and the feeding plate A101 from rotating, so as to achieve material taking.

[0078] All three of the above embodiments can achieve rotary feeding of the sealing ring and the wheel hub bearing. The appropriate embodiment can be selected based on actual needs. This embodiment uses embodiment one. Figure 12 , 13 direction shown;

[0079] Finally, please see Figure 9 ,Figure 10 In this embodiment, the pressing mechanism 400 includes a vacuum adsorption head 401, a lifting motion module 402, and a vacuum system 403. The lifting motion module 402 is fixedly connected to the rotating main shaft 302. The lifting motion module 402 includes a lifting platform 4021 capable of lifting linear motion. The vacuum adsorption head 401 is fixedly connected to the lifting platform 4021. The vacuum system 403 is provided on the rotating main shaft 302 and cooperates with the vacuum adsorption head 401.

[0080] When the drive device 301 drives the pressing mechanism 400 to rotate, the vacuum suction head 401 can correspond to the sealing ring on the feeding tray A101 or the part of the wheel hub bearing on the feeding tray B201 to be pressed.

[0081] The lifting motion module 402 lowers the vacuum suction head 401, which then, in conjunction with the vacuum system 403, picks up the sealing ring. This non-contact, non-damaging method of gripping the sealing ring is ideal for easily deformable rubber seals, avoiding scratches or deformation that might occur with mechanical clamping. After picking up the ring, the lifting motion module 402 raises it again. Then, the drive device 301 rotates the main shaft 302 by a predetermined angle, aligning the vacuum suction head 401 with the wheel hub bearing. The lifting motion module 402 then lowers the vacuum suction head 401 until... The sealing ring is pressed into the wheel hub bearing. After the pressing is completed, the vacuum system 403 releases the vacuum state of the vacuum adsorption head 401, and the lifting motion module 402 drives the vacuum adsorption head 401 to rise. This cycle is repeated to realize the pressing of the sealing ring into the wheel hub bearing. Combined with the continuous feeding of the rotary feeding mechanism A100 and the rotary feeding mechanism B200, the pressing mechanism 400 can work alternately between the A and B stations (taking the sealing ring and pressing), forming a continuous production cycle. This realizes full automation from feeding to pressing, reduces intermediate material handling and manual intervention, stabilizes the cycle time, and significantly improves production efficiency.

[0082] Furthermore, the rotary feeding mechanism A100 and rotary feeding mechanism B200 do not require additional electrical control signals or sensors to control the start and stop of the two feeding discs respectively. They achieve perfect synchronization and interlocking with the rotational motion of the main shaft through a purely mechanical structure. The structure is ingenious, highly reliable, low in cost and low in failure rate.

[0083] To elaborate further, please refer to Figure 11In this embodiment, the lifting motion module 402 further includes a module platform 4022, a sliding column 4023, a lead screw 4024, and a drive motor 4025. The module platform 4022 is fixedly connected to the rotating main shaft 302. The sliding column 4023 is fixedly connected to the module platform 4022. A lifting platform 4021 is slidably connected to the sliding column 4023. The lead screw 4024 is threadedly connected to the lifting platform 4021. The drive motor 4025 is fixedly connected to the module platform 4022. The motor 4025 is powered by the lead screw 4024. That is to say, when the drive motor 4025 drives the lead screw 4024 to rotate, the lifting platform 4021 can perform vertical linear motion. The lead screw 4024 module is used here, which can provide precise and controllable pressing stroke and pressure, ensuring that each sealing ring is pressed to a consistent depth and position, thus ensuring the stability of product quality. In addition, a mounting platform is fixedly connected to the module platform 4022, and a vacuum system 403 is provided on the mounting platform.

[0084] Further optimized, the vacuum system 403 includes a vacuum breaker valve 4031, which is fixedly connected to the lifting platform 4021. The vacuum breaker valve includes a valve shaft 4032 for driving the valve body to reverse direction. A rotating gear 4033 is fixedly connected to the valve shaft 4032. A drive rack 4034 is fixedly connected to the module platform 4022. When the lifting platform 4021 drives the vacuum adsorption head 401 to descend and contact the hub bearing at the press-fit position, as it continues to descend, the drive rack 4034 drives the rotating gear 4033 to rotate, thus disrupting the vacuum environment of the vacuum adsorption head 401. Conversely, this allows... Vacuum breaker valve 4031 returns to its original position. Once the suction head has descended and is press-fitted into place, a slight downward stroke will trigger the rack and pinion drive gear, opening the vacuum breaker valve. This ensures the sealing ring is reliably released and installed onto the bearing, preventing it from sticking to the suction head. The vacuum breaker valve's action is triggered by the drive rack 4034 and rotating gear 4033 mechanism, requiring no sensors or electrical control signals. It mechanically senses the physical signal of "press-fitted in place" before releasing the vacuum. This avoids premature release or overload damage to the workpiece before proper press-fitting, providing simple protection and reducing the number of electrical drive components, thus lowering the equipment failure rate.

[0085] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
