Description

Technical Field

[0001] This invention relates to the field of one-way clutch assembly technology, and more specifically to an automatic one-way clutch assembly device and its assembly method. Background Technology

[0002] A one-way clutch is a mechanical transmission element that allows torque to be transmitted between the driving shaft and the driven shaft in only one direction, and automatically separates when they are in the opposite direction. Its core working principle usually relies on the cooperation between the wedge (or roller), the cage, the spring, and the raceways of the inner and outer rings. When the inner ring (or outer ring) rotates relative to the other in a specific direction, the wedge wedges into the wedge-shaped space between the inner and outer rings under the action of friction, thereby locking the torque transmission; conversely, it exits the wedge-shaped space, allowing freewheeling and overtaking.

[0003] With the increasing demands for transmission system performance in the automotive, precision machine tool, and aerospace industries, one-way clutches are evolving towards higher speeds, higher torques, longer lifespans, and smaller sizes. Under high-speed conditions or those with axial impact, the wedge and cage assemblies are prone to axial movement, leading to abnormal noise, accelerated wear, and even failure. To address these issues, traditional metal cages are gradually being replaced by engineering plastics (such as PA66 and PEEK). New plastic cages, manufactured using a one-piece injection molding process, feature an outer flange formed by an integral extension of material on one side. This outer flange precisely embeds into a pre-machined annular groove on the inner wall of the one-way clutch outer ring, effectively limiting axial movement and achieving stable axial positioning. To reduce assembly difficulty and prevent interference, a 30° guide slope is machined at the outer edge of the outer flange (the edge that finally enters the annular groove), ensuring a good balance between smooth guidance and structural strength.

[0004] However, existing automated assembly equipment and processes for one-way clutches still have the following significant technical shortcomings when facing the demands of new material structures and high-efficiency production:

[0005] 1. Most of the existing mainstream assembly equipment adopts a multi-station turntable structure, which sequentially performs the actions of "placing the outer ring → placing the retainer → filling the wedges one by one → installing the springs one by one". This sequential assembly mode of disassembled parts is cumbersome and difficult to meet the needs of large-scale mass production. Furthermore, placing small parts one by one in a narrow annular space is prone to cumulative errors due to positioning. In addition, the lack of an overall pre-alignment process makes it difficult to control the uniformity of wedge distribution and the consistency of spring preload in the final product.

[0006] 2. For plastic cages with guide ramps, traditional equipment usually uses a rigid metal indenter for vertical pressing. Due to the low elastic modulus and relatively high brittleness of plastic materials (especially PA66), point or line contact is often formed between the rigid indenter and the cage ramp, resulting in high stress concentration in the contact area. During the pressing process, plastic edge breakage, ramp scratches, or even the entire cage breakage are very likely to occur.

[0007] 3. The performance of a one-way clutch is highly dependent on the micron-level axial clearance (typically 0.05mm-0.15mm) formed between the cage retainer and the outer ring annular groove. Traditional equipment relies on mechanical limit blocks (hard stop) to control the pressing depth, which cannot compensate for the cumulative dimensional tolerances of parts such as the outer ring groove depth and cage thickness, and it is also difficult to detect sudden changes in resistance during the pressing process (such as the "click" feeling when the retainer enters the groove). This "blind assembly" mode results in poor consistency of the finished product clearance, which often requires subsequent manual re-inspection or screening, increasing production costs.

[0008] Furthermore, in order to address the problem mentioned in technical defect 1 (the traditional "assembly of individual parts" process is inefficient and has poor precision), a new one-way clutch assembly method has emerged: the rolling elements (balls or needle rollers) are first placed on the bottom layer of the inner and outer rings and assembled, with a reserved upper channel specifically for installing the wedge assembly (a pre-assembled assembly consisting of wedges, cage, and springs), and finally sealed with a sealing ring. However, existing general assembly equipment is completely unable to adapt to this structure and method. The main obstacle is that the springs in the pre-assembled assembly are in a pre-compressed state and have a huge radial expansion force. If this assembly is directly and forcibly pressed into the narrow gap between the assembled inner and outer rings, the wedges will rub violently under the action of the spring force and may even seize the precision raceways of the inner and outer rings. This will not only cause a sharp increase in downward pressure, which will crush the plastic cage, but will also severely damage the precision raceways that have been hardened and ground, leading to clutch performance failure.

[0009] Therefore, it is necessary to invent an automatic assembly device for a one-way clutch and its assembly method. Summary of the Invention

[0010] To achieve the above objectives, the present invention provides the following technical solution: an automatic assembly equipment for a one-way clutch, comprising a dual adsorption table frame, an adaptive flexible inner support feeding unit, and an intelligent flexible pressing unit;

A sliding rod is installed at the front end of the return spring and slidably mounted within the cavity. The front end of the sliding rod extends out of the inner support slider and is fixedly mounted on a locking tooth plate. The surface of the locking tooth plate has grooves that can engage with the micro-teeth on the surface of the micro external tooth roller.

[0017] Preferably, the intelligent flexible pressing head includes a C-shaped bracket, which is fixedly installed at the lower end of the pressing rod. Several limiting skeletons are installed in a ring at the bottom of the C-shaped bracket. The flexible airbag is bonded to the bottom of the limiting skeleton, and the air pressure sensor is installed at the top of the limiting skeleton.

[0018] Preferably, the pre-assembly turntable is rotatably mounted on the work platform. The bottom of the pre-assembly turntable is provided with a plurality of ball bearings. The surface of the work platform is provided with an annular groove for the ball bearings to roll. A boss is provided at the center of the top of the pre-assembly turntable.

The surface of the pre-assembly turntable is provided with a plurality of first adsorption holes connecting to its vacuum chamber, and the surface of the final assembly positioning table is provided with a plurality of second adsorption holes connecting to its vacuum chamber.

[0019] Preferably, the pre-assembled vacuum adsorption mechanism includes a first vacuum pump chamber, which is installed at the bottom of the working platform. The upper end of the first vacuum pump chamber is connected to the vacuum chamber at the bottom of the pre-assembled turntable, and a first servo electric thruster is installed at the lower end. A first pump rod is installed at the output end of the first servo electric thruster, and the upper end of the first pump rod is inserted into the lower end of the first vacuum pump chamber.

[0020] Preferably, the final assembly vacuum adsorption mechanism includes a second vacuum pump chamber, which is installed at the bottom of the assembly platform.

A second pump rod is installed at the output end of the second servo electric thruster, and the upper end of the second pump rod is inserted into the lower end of the second vacuum pump chamber.

[0021] Preferably, a central control screen is installed on the front of the upper rack, and a power supply and a central control box are installed inside the lower rack. The central control box, the power supply, and the central control screen are electrically connected to each other.

[0022] The assembly method of the one-way clutch automatic assembly equipment described above includes S1-S5;

[0023] S1. The rolling elements are pre-arranged at the bottom of the inner and outer ring grooves of the bearing. The rolling element cage is pressed between the inner and outer rings of the bearing and combined with the evenly distributed rolling elements to form a combined semi-finished product. The first sealing ring is installed on the bottom surface of the combined semi-finished product, and the wedge block installation channel on the top surface is reserved. Then the combined semi-finished product is placed on the final assembly positioning table. The final assembly vacuum adsorption mechanism is started to create a vacuum in the vacuum cavity at the bottom of the final assembly positioning table, and the combined semi-finished product is adsorbed and positioned through the second adsorption hole.

[0024] S2. Next, place the wedge retainer on the pre-assembly turntable, activate the pre-assembly vacuum adsorption mechanism to create a vacuum in the vacuum chamber at the bottom of the pre-assembly turntable, and adsorb and position the wedge retainer through the first adsorption hole. Rotate the pre-assembly turntable, and at the same time, fill the window frame of the wedge retainer one by one. Then install the wedge springs to form the pre-assembly assembly.

[0025] S3. Control the servo sliding mechanism to drive the tracked inner support clamp to extend into the inside of the pre-assembly turntable, close the pre-assembly vacuum adsorption mechanism, and at the same time start the center telescopic drive mechanism to drive the inner support slider to push outward until the surface of the inner tooth belt on the outside of the micro external tooth roller tightly presses against the inside of the pre-assembly assembly, forcibly offsetting the preload of the wedge spring. Then, start the locking actuator to lock the micro external tooth roller, thereby achieving the inner support clamping of the pre-assembly assembly.

[0026] S4. Next, the servo sliding mechanism is controlled to move the tracked inner support clamp and the pre-assembled assembly to the top of the assembled semi-finished product. The position of the pre-assembled assembly is adjusted so that its lower end is precisely aligned with the reserved wedge installation channel. At the same time, the servo electric downward pusher is started to drive the downward push rod to drive the intelligent flexible pressing head to press the pre-assembled assembly. When the flexible airbag contacts the top of the pre-assembled assembly and establishes a stable contact pressure, the locking actuator is controlled to release the micro external tooth roller, so that the internal tooth belt changes from the locked state to the free rolling state. Then the internal tooth belt drives the pre-assembled assembly downward. The wedge has no radial contact friction with the inner and outer raceways.

[0027] S5. During the press-fitting process of the intelligent flexible press-fitting head on the released pre-assembled assembly, the air pressure fluctuations in the flexible airbag are monitored by the air pressure sensor throughout the process. At the same time, the air pressure sensing feedback system in the central control box plots the pressure-displacement curve of the press-fitting process in real time. When the curve detects a characteristic "pressure drop followed by recovery" waveform, it is determined that the outer edge of the wedge retainer has been successfully engaged in the annular groove of the bearing outer ring. The control system immediately stops the press-fitting action to ensure the consistency of the axial clearance. Finally, the second sealing ring is installed to complete the assembly.

[0028] The beneficial effects of this invention are:

[0029] 1. This invention is adapted to modular pre-assembled assemblies (pre-assembled wedge-spring-cage assemblies), abandoning the inefficient mode of traditional equipment that fills wedges and springs one by one. By grabbing and accurately implanting the entire assembly at once, it achieves the overall efficient implantation of modular pre-assembled assemblies, breaking through the bottleneck of traditional component assembly. It not only shortens the assembly cycle of a single part by more than 50%, but also eliminates the risks of cumulative errors, part tipping and misalignment that are common in component assembly, significantly improving product consistency and production efficiency, and providing a brand-new process route for large-scale automated production.

[0030] 2. To address the brittle nature of engineering plastic cages, this invention employs a dual flexible protection strategy: First, at the clamping end, a high-friction internal toothed belt of a tracked internal support clamp forms surface contact with the inner contour of the pre-assembled assembly, evenly distributing the clamping force and avoiding stress concentration and localized crushing caused by rigid grippers; second, at the pressing end, a flexible airbag is used with an intelligent flexible pressing head for pressing, which can adapt to slight tilts and unevenness of the assembly end face, achieving soft surface contact pressing; this dual flexible protection strategy effectively prevents plastic edge chipping and bevel scratches, and is particularly suitable for high-strength, highly brittle new engineering plastic materials;

[0031] 3. This invention integrates a pneumatic sensing feedback system, which monitors and plots the pressure-displacement curve during the pressing process in real time through a pneumatic sensor. The system can keenly capture the characteristic waveform of the outer edge of the cage entering the outer ring annular groove (such as the pressure rising after a sudden drop), and use this as a precise criterion for pressing termination. This "sensory" closed-loop control replaces the traditional mechanical limit "blind assembly", which can automatically compensate for the dimensional tolerance of parts and ensure that the axial micro gap (0.05mm-0.15mm) of each product is highly consistent, which greatly reduces the cost of subsequent manual re-inspection and screening.

[0032] 4. This invention uses a track-type internal support clamp to actively apply a reverse radial force during assembly, forcibly counteracting the huge preload of the spring inside the pre-assembled assembly, and firmly "locking" the wedge block in the cage window. This allows the overall outer diameter of the assembly to be minimized when entering the narrow gap between the inner and outer rings, achieving zero radial friction and zero raceway scratches for non-destructive sliding. This innovative mechanism fundamentally solves the fatal defects caused by forced insertion in traditional processes, such as raceway scratches, wedge block chipping, and cage breakage, greatly improving product reliability and yield.

[0033] 5. During the assembly release phase, the micro external toothed roller of the gripper is switched from "locked state" to "free rolling state" by controlling the locking actuator; when the intelligent flexible pressing head pushes the assembly downward, the sliding friction between the inner wall of the assembly and the internal toothed belt changes to rolling friction; this design not only further reduces the wear on the wedge, but also eliminates the risk of instantaneous impact and jamming when the traditional clamp is released, ensuring a smooth and safe release process.

[0054] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0055] like Figure 1 - Figure 5 , Figure 11 , Figure 15 - Figure 19 As shown, an automatic assembly equipment for a one-way clutch includes a dual adsorption table frame, an adaptive flexible inner support feeding unit, and an intelligent flexible pressing unit.

[0056] The dual adsorption table frame includes a work platform 111, a back plate 113 mounted on the back of the work platform 111, a lower frame 112 mounted on the bottom of the work platform 111, an assembly table 116 mounted on one side of the top, and a pre-assembly assembly positioning component mounted on the other side. The pre-assembly assembly positioning component includes a pre-assembly turntable 121, and a pre-assembly vacuum adsorption mechanism is provided below the pre-assembly turntable 121. A bearing inner and outer ring positioning component is mounted on the assembly table 116, and the bearing inner and outer ring positioning component includes a final assembly positioning table 131. A final assembly vacuum adsorption mechanism is provided below the final assembly positioning table 131. An upper frame 114 is mounted on the back plate 113 and is positioned directly above the assembly table 116.

[0057] The adaptive flexible internal support feeding unit includes a servo sliding mechanism, which includes a vertical electric slide table 144. A tracked internal support clamp is installed on the vertical electric slide table 144. The tracked internal support clamp includes a central telescopic drive mechanism, several flexible track modules distributed along the circumference, and a locking execution mechanism. The flexible track module includes an internal support slider 157. A miniature external toothed roller 158 is rotatably installed at the front end of the internal support slider 157. An internal toothed belt 159 is sleeved on the miniature external toothed roller 158.

[0058] The intelligent flexible pressing unit includes a servo electric pressing pusher 171, which is mounted on the upper frame 114. A pressing rod 172 is installed at the output end of the servo electric pressing pusher 171. An intelligent flexible pressing head is provided at the lower end of the pressing rod 172. The intelligent flexible pressing head includes a flexible airbag 175, and a pressure sensor 176 is installed inside the flexible airbag 175.

[0059] In the above embodiments, it should be noted that the present invention is adapted to a novel wedge-type one-way clutch. Traditional wedge-type one-way clutches are prone to axial movement of the wedge and cage assembly under high-speed or axial impact conditions, leading to abnormal noise, increased wear, or even failure. Moreover, traditional clutches often use additional independent parts such as retaining rings and gaskets, or rely on high-precision chain clamping to achieve axial positioning. The novel wedge-type one-way clutch adapted to the present invention includes a brand-new wedge cage 185. This wedge cage 185 is a ring structure with multiple windows evenly or non-uniformly opened in its circumference. Each window is used to accommodate the wedge 186 of the one-way clutch.

[0060] The key improvement of the new wedge-type one-way clutch lies in the fact that the cross-section of the wedge retainer 185 is designed to be axially asymmetrical. Specifically, an outer flange is formed on one side of the wedge retainer 185 by integrally extending the material. The core purpose of this structural design is to achieve reliable axial positioning of the wedge retainer 185 within the outer ring of the clutch. In the assembled state, the aforementioned outer flange can be precisely embedded into the pre-machined annular groove on the inner wall of the one-way clutch bearing outer ring 181. By the side of the outer flange abutting against the corresponding side wall of the annular groove, the axial movement of the wedge retainer 185 is effectively restricted, achieving a stable axial limiting fit.

[0061] For this novel wedge-type one-way clutch, this invention proposes a compatible assembly method. By constructing a modular pre-assembled assembly (pre-assembled wedge 186 - wedge spring 187 - wedge retainer 185), it abandons the inefficient mode of manually filling wedge 186 and wedge spring 187 one by one in traditional equipment. By grabbing and accurately implanting the entire assembly at once, it achieves the overall efficient implantation of the modular pre-assembled assembly, breaking through the bottleneck of traditional component assembly. This not only shortens the assembly cycle time of a single component by more than 50%, but also eliminates the risks of cumulative errors, component tipping, and misalignment commonly encountered in component assembly, significantly improving product consistency and production efficiency, and providing a brand-new process route for large-scale automated production.

[0062] To address the brittle nature of engineering plastic retainers (wedge retainers 185), this invention employs a dual flexible protection strategy: First, at the clamping end, a high-friction internal toothed belt 159 of a tracked internal support clamp forms surface contact with the inner contour of the pre-assembled assembly, evenly distributing the clamping force and avoiding stress concentration and localized crushing caused by rigid grippers; second, at the pressing end, a flexible press head uses a flexible airbag 175 for pressing, which can adapt to slight tilts and unevenness of the assembly end face, achieving soft surface contact pressing; this dual flexible protection strategy effectively prevents plastic edge chipping and bevel scratches, and is particularly suitable for high-strength, highly brittle new engineering plastic materials;

[0063] This invention integrates a pneumatic sensing feedback system, which monitors and plots the pressure-displacement curve during the pressing process in real time through a pneumatic sensor 176. The system can keenly capture the characteristic waveform of the outer edge of the cage entering the outer annular groove (such as the pressure rising after a sudden drop), and use this as a precise criterion for pressing termination. This "sensory" closed-loop control replaces the traditional mechanical limit "blind assembly", which can automatically compensate for the dimensional tolerance of parts and ensure that the axial micro gap (0.05mm-0.15mm) of each product is highly consistent, which greatly reduces the cost of subsequent manual re-inspection and screening.

[0064] This invention utilizes a track-type internal support clamp to actively apply a reverse radial force during assembly, forcibly counteracting the enormous preload of the wedge spring 187 inside the pre-assembled assembly, thus firmly "locking" the wedge 186 within the window of the wedge retainer 185. This minimizes the overall outer diameter of the assembly when it enters the narrow gap between the inner and outer rings, achieving zero radial friction and zero raceway scratches during non-destructive sliding. This innovative mechanism fundamentally solves the fatal defects of traditional processes, such as raceway scratches, wedge chipping, and retainer breakage caused by forced insertion, greatly improving product reliability and yield.

[0065] During the assembly release phase, the micro external toothed roller 158 of the gripper is switched from "locked state" to "free rolling state" by controlling the locking actuator; when the intelligent flexible pressing head pushes the assembly downward, the sliding friction between the inner wall of the assembly and the internal toothed belt 159 changes to rolling friction; this design not only further reduces the wear on the wedge 186, but also eliminates the instantaneous impact and jamming risk when the traditional clamp is released, ensuring a smooth and safe release process;

[0066] The pre-assembly turntable 121 is used to assist workers in assembling pre-assembly assemblies. The specific assembly method is as follows: First, place the wedge retainer on the pre-assembly turntable 121, start the pre-assembly vacuum adsorption mechanism to adsorb and position the wedge retainer 185, rotate the pre-assembly turntable 121, and at the same time, fill the window frame of the wedge retainer 185 one by one with the wedges 186, and finally install the wedge spring 187 to quickly build the pre-assembly assembly.

[0067] The final assembly positioning table 131 is used to place the assembled semi-finished product (the rolling elements 183 are pre-laid on the bottom layer of the bearing outer ring 181, and the bearing inner ring 182 is pressed into the bearing outer ring 181 to form the semi-finished product). The top of the assembled semi-finished product has a pre-assembled assembly installation channel. By placing the assembled semi-finished product on the final assembly positioning table 131, the final assembly vacuum adsorption mechanism is activated to achieve the adsorption and positioning effect of the assembled semi-finished product.

[0068] like Figure 1 , Figure 2 , Figure 4 - Figure 10As shown, an automatic assembly device for a one-way clutch further includes a servo sliding mechanism comprising a transverse servo electric slide 141 mounted on a back plate 113, a transverse electric slide 142 slidably mounted on the transverse servo electric slide 141, a vertical servo electric slide 143 mounted on the transverse electric slide 142, and a vertical electric slide 144 slidably mounted on the vertical servo electric slide 143. A central telescopic drive mechanism includes a screw housing 151, and a screw... The housing 151 is fixedly mounted on the vertical electric slide table 144. An inner support end 152 is installed at the lower end of the housing 151, and a screw motor 153 is installed at the upper end. A screw 154 is installed at the lower output end of the screw motor 153. The screw 154 passes downward through the housing 151 and extends into the inner support end 152. An octagonal slider 155 is slidably mounted on the inner wall of the inner support end 152. The octagonal slider 155 is threaded onto the outer wall of the screw 154. Sliding grooves are formed around the inner support end 152. The inner support sliders 157 are slidably installed in the grooves around the inner support end 152. An octagonal slider 155 is rotatably mounted with connecting rods 156 around its perimeter. The lower end of the connecting rods 156 is rotatably connected to the inner support sliders 157. The locking actuator includes an air pump 161, which is mounted on a vertical electric slide table 144. A flow-diverting cavity 163 is provided inside the upper end of the screw housing 151. An air injection pipe 162 is installed between the output end of the air pump 161 and the flow-diverting cavity 163. The inner support slider 157 contains... A diversion pipe 164 connects the cavity, the diversion inner cavity 163 and the cavity of the inner support slider 157. A return spring 165 is installed in the cavity of the inner support slider 157. A sliding rod 166 is installed at the front end of the return spring 165. The sliding rod 166 is slidably installed in the cavity. The front end of the sliding rod 166 extends out of the inner support slider 157 and is fixedly installed with a locking tooth plate 167. The surface of the locking tooth plate 167 is provided with tooth grooves. The tooth grooves on the surface of the locking tooth plate 167 can engage with the micro teeth on the surface of the micro external tooth roller 158.

[0069] In the above embodiments, it should be noted that the transverse electric slide 142 and the vertical electric slide 144 are both high-precision mechatronic execution units, which belong to the prior art. The working principle of various servo electric slides in this case is the same, specifically: by controlling the servo motor on the servo electric slide to drive the lead screw to rotate, the slide is driven to move smoothly along the linear guide.

[0070] The horizontal electric slide 142 is driven to move horizontally by activating the horizontal electric slide 142, thereby driving the tracked internal support clamp to move horizontally; the vertical electric slide 144 is controlled to move up and down by activating the vertical servo electric slide 143, thereby driving the tracked internal support clamp to move up and down.

[0071] The working principle of the central telescopic drive mechanism is as follows: by controlling the start screw motor 153 to drive the screw 154, the screw 154 drives the octagonal slider 155 to slide along the inner wall of the inner support end 152. When the octagonal slider 155 slides downward, it can drive the connecting rod 156 to deflect, thereby pushing the inner support slider 157 to slide outward, so that the miniature external toothed roller 158 and the internal toothed belt 159 at the front end of the inner support slider 157 expand outward and abut against the inner contour of the pre-assembled assembly, so as to achieve the effect of clamping the pre-assembled assembly.

[0072] The working principle of the locking actuator is as follows: Air pump 161 is activated to inject air into the distribution cavity 163 via air injection pipe 162. The high-pressure gas in the distribution cavity 163 enters the rear end of each inner support slider 157 cavity through distribution pipe 164, causing the pressure inside the inner support slider 157 cavity to rise and push the sliding rod 166 to extend. The sliding rod 166 drives the locking tooth plate 167 to engage with the micro-teeth on the surface of the miniature external toothed roller 158, thereby locking the miniature external toothed roller 158 and keeping it in a "locked state." Furthermore, the outer wall of the miniature external toothed roller 158 contacts the inner toothed belt 159. Fine teeth are also distributed on some parts, and fine teeth are also distributed on the inner wall of the inner toothed belt 159, which can ensure that sufficient friction is maintained between the miniature outer toothed roller 158 and the inner toothed belt 159 in the "locked state" and the inner toothed belt 159 will not slip. Then, by turning off the air pump 161, the pressure in the cavity of the inner support slider 157 decreases. At this time, the return spring 165 pulls the sliding rod 166 to retract. The sliding rod 166 drives the locking tooth plate 167 to separate from the surface of the miniature outer toothed roller 158, so as to release the miniature outer toothed roller 158 and keep it in the "free rolling state".

[0073] like Figure 1 - Figure 3 and Figure 15 As shown, an automatic assembly device for a one-way clutch further includes an intelligent flexible pressing head comprising a C-shaped bracket 173, which is fixedly installed at the lower end of a lower pressing rod 172. Several limiting frames 174 are arranged in a ring at the bottom of the C-shaped bracket 173. A flexible airbag 175 is bonded to the bottom of the limiting frame 174. A pressure sensor 176 is installed at the top of the limiting frame 174, with the lower end of the pressure sensor 176 extending downward into the flexible airbag 175. A central control screen 115 is installed on the front of the upper frame 114. A power supply 117 and a central control box 118 are installed inside the lower frame 112. The central control box 118, the power supply 117, and the central control screen 115 are electrically connected to each other.

[0074] In the above embodiment, it should be noted that by activating the servo electric pressing pusher 171, the pressing rod 172 is driven downward, and the pressing rod 172 drives the C-shaped bracket 173 and the flexible airbag 175 at its bottom to contact the top of the pre-assembled assembly until the flexible airbag 175 contacts the top of the pre-assembled assembly and establishes a stable contact pressure, the pressing work can be officially carried out.

[0075] The Flexible Airbag 175 employs a unique "rigid-flexible coupled dual-layer airbag structure," designed to simultaneously achieve high-response force transmission and perfect surface contact self-adaptation capability, specifically:

[0076] (1) Inner pressure-bearing bladder: Made of high-strength, low-deformation aramid fiber reinforced rubber, in the shape of a flat cylinder; its function is to act as a "hydraulic skeleton", quickly respond to changes in air pressure, convert the air source pressure into a stable axial thrust, and ensure that excessive volume expansion will not occur when encountering resistance, resulting in energy loss; the inner pressure-bearing bladder is responsible for providing the main downforce and serves as the direct force-bearing surface of the air pressure sensor 176, ensuring the real-time and accuracy of pressure signal acquisition;

[0077] (2) Outer contact bladder: Wrapped around the inner pressure bladder, it is made of corrugated tubing with ultra-soft silicone. Its wall thickness is designed to be 1.5mm-2.5mm, and the surface is provided with annular reinforcing ribs to prevent lateral buckling. The outer contact bladder is responsible for physical contact with the end face of the pre-assembled assembly. Due to its extremely high flexibility, when the pressure head contacts the tilted or uneven end face of the plastic cage, the outer bladder can instantly fill the tiny gaps like "water flow", transforming point contact into full-section surface contact and completely eliminating stress concentration.

[0078] (3) Connection and sealing: The inner and outer bladders are sealed to the aluminum alloy limiting skeleton 174 at the bottom by high-strength adhesive. The pressure sensor 176 (accuracy ±0.1%FS) is built into the limiting skeleton 174 to directly read the real-time pressure of the inner bladder.

[0079] The central control box 118 adopts a double-layer heat insulation and dustproof structure with an IP54 protection level to adapt to dust and oil mist in the workshop environment. The central control box 118 is equipped with: a core controller (such as Siemens S7-1500 or Beckhoff TwinCAT series PLC), motion control card, high-speed data acquisition module (for acquiring airbag pressure waveforms) and industrial Ethernet switch. It also houses servo drivers, high-power relays, pneumatic solenoid valve groups and power filtering units. Power lines and signal lines are strictly laid out in layers with metal shielding partitions in between to effectively eliminate electromagnetic interference (EMI) generated by the high-frequency start and stop of the servo motor and ensure the purity of the air pressure sensor 176 signal.

[0080] Power supply 117 adopts a three-level voltage regulation and purification power supply system, and central control screen 115 adopts a 15-inch industrial-grade capacitive touch screen. Its software interface is developed based on SCADA (data acquisition and monitoring control) architecture and has a dedicated "pressure waveform monitoring page" to draw and store the PS curve (pressure-displacement curve) of each assembly in real time.

[0081] The core innovation of the invention lies in using the characteristic waveform of the pressure-displacement curve (P-SCurve) to accurately determine the assembly status, replacing the traditional mechanical limit, and controlling the system to sample pressure data in real time (frequency ≥1kHz).

[0082] Detailed explanation of waveform stages:

[0083] (1) Contact establishment period (segment A - pressure rises slowly);

[0084] Process description: The pressure head descends and contacts the top of the assembly. As the cylinder thrust increases, the soft silicone undergoes elastic deformation to conform to the end face;

[0085] Waveform characteristics: The pressure P increases linearly and slowly with the displacement S, with a relatively small slope k1. At this point, the wedge has not yet entered the outer groove.

[0086] (2) Friction climbing period (Section B - steep pressure increase)

[0087] Process description: The assembly is pushed into the gap between the inner and outer rings. Due to incomplete release of the spring preload or slight interference, sliding friction occurs between the back of the wedge and the raceway;

[0088] Waveform characteristics: Pressure P rises sharply, and the slope k2 increases significantly (satisfying k2>k1). The system detects this stage and confirms that the assembly is descending smoothly;

[0089] (3) Transient period upon entering the tank (C section - sudden pressure drop, i.e. "drop trough");

[0090] Critical moment: When the axial snap-ringland of the cage reaches the entrance of the outer ring groove, the snap-ringland slides into the groove instantly under the action of axial thrust;

[0091] Physical phenomenon: Due to the sudden release of axial constraints (from "pressed against the wall" to "falling into the pit"), the system resistance disappears instantly;

[0092] Waveform characteristics: The pressure curve shows a distinct downward peak (Drop), with the pressure drop ΔP typically ranging from 15% to 25% of the working pressure. This is the key characteristic signal for this patent to identify "on-time" pressure.

[0093] (4) Rebound and stabilization period (Segment D - Pressure rises and stabilizes)

[0094] Process description: After the retaining edge has completely fallen into the bottom of the groove, further pressing down will cause the bottom seal ring of the cage to be compressed or to abut against the step, and the resistance will increase again;

[0095] Waveform characteristics: The pressure rises rapidly from the trough and stabilizes at a preset target value;

[0096] Control Action: Once the control system detects the complete waveform sequence of "sharp rise → sudden drop → rebound", it immediately determines that the assembly is complete and cuts off the air supply and maintains pressure within milliseconds to prevent overpressure damage to parts.

[0097] like Figure 1 , Figure 2 , Figure 10 - Figure 14 As shown, an automatic assembly device for a one-way clutch further includes a pre-assembly turntable 121 rotatably mounted on a working platform 111. The bottom of the pre-assembly turntable 121 is provided with a plurality of balls 126. The surface of the working platform 111 is provided with an annular groove for the balls 126 to roll. A boss is provided at the center of the top of the pre-assembly turntable 121, on which a wedge retainer can be fitted. The outer surface of the boss of the pre-assembly turntable 121 is provided with a plurality of grooves that can fit the wedges 186. Both the pre-assembly turntable 121 and the final assembly positioning table 131 have vacuum chambers at their bottoms. The surface of the pre-assembly turntable 121 is provided with a plurality of first adsorption holes 122 connecting to its vacuum chamber. The surface of the final assembly positioning table 131 is provided with a plurality of second adsorption holes 132 connecting to its vacuum chamber. A pre-assembly vacuum adsorption machine is also included. The structure includes a first vacuum pump chamber 123, which is installed at the bottom of the work platform 111. The upper end of the first vacuum pump chamber 123 is connected to the vacuum chamber at the bottom of the pre-assembly turntable 121, and the lower end is equipped with a first servo electric thruster 125. A first pump rod 124 is installed at the output end of the first servo electric thruster 125, and the upper end of the first pump rod 124 is inserted into the lower end of the first vacuum pump chamber 123. The final assembly vacuum adsorption mechanism includes a second vacuum pump chamber 133, which is installed at the bottom of the assembly table 116. The upper end of the second vacuum pump chamber 133 is connected to the vacuum chamber at the bottom of the final assembly positioning table 131, and the lower end is equipped with a second servo electric thruster 135. A second pump rod 134 is installed at the output end of the second servo electric thruster 135, and the upper end of the second pump rod 134 is inserted into the lower end of the second vacuum pump chamber 133.

[0098] In the above embodiments, it should be noted that the first servo electric thruster 125, the second servo electric thruster 135 and the servo electric downward thruster 171 are all high-precision mechatronic execution units, which belong to the prior art. The working principle of the various servo electric slides in this case is the same, specifically: by controlling the servo motor on the servo electric slide to drive the lead screw to rotate, the slide rod is driven to move smoothly along the linear guide.

[0099] By activating the first servo electric thruster 125 to drive the first pump rod 124 to retract, a vacuum is created in the vacuum chamber at the bottom of the first vacuum pump chamber 123 and the pre-assembly turntable 121, and the wedge retainer 185 is adsorbed and positioned through the first adsorption hole 122; by activating the second servo electric thruster 135 to drive the second pump rod 134 to retract, a vacuum is created in the vacuum chamber at the bottom of the second vacuum pump chamber and the final assembly positioning table 131, and the assembled semi-finished product is adsorbed and positioned through the second adsorption hole 132.

[0100] An assembly method for an automatic assembly device for a one-way clutch according to the present invention: Those skilled in the art pre-arrange rolling elements 181 at the bottom of the inner and outer ring grooves of the bearing. A rolling element retainer is pressed between the inner and outer rings of the bearing and engages with the evenly distributed rolling elements 181 to form a semi-finished product. A first sealing ring is installed on the bottom surface of the semi-finished product, while a wedge block installation channel is reserved on the top surface. The semi-finished product is then placed on the final assembly positioning table 131. The second servo electric thruster 135 is activated to drive the second pump rod 134 to retract, creating a vacuum in the second vacuum pump chamber and the vacuum cavity at the bottom of the final assembly positioning table 131. The semi-finished product is then adsorbed and positioned through the second adsorption hole 132. Next, the wedge block retainer 181... 85 is placed on the pre-assembly turntable 121. The first servo electric thruster 125 is activated to drive the first pump rod 124 to retract, creating a vacuum in the first vacuum pump chamber 123 and the vacuum chamber at the bottom of the pre-assembly turntable 121. The wedge retainer 185 is then adsorbed and positioned through the first adsorption hole 122. The pre-assembly turntable 121 is rotated, and wedges 186 are filled into the window frame of the wedge retainer 185 one by one. Then, the wedge springs 187 are installed to form the pre-assembly assembly. The servo sliding mechanism is controlled to drive the tracked inner support clamp to extend into the inside of the pre-assembly turntable 121, and the pre-assembly vacuum adsorption mechanism is closed. At the same time, the screw motor 153 is controlled to drive the screw 154. Now, the screw 154 drives the octagonal slide... Block 155 slides along the inner wall of the inner support end 152. When the octagonal slider 155 slides downward, it can drive the connecting rod 156 to deflect, thereby pushing the inner support slider 157 to slide outward until the surface of the inner tooth belt 159 on the outer side of the miniature external tooth roller 158 tightly presses against the inner side of the pre-assembled assembly, forcibly offsetting the preload force of the wedge spring 187. Then, the air pump 161 is started to inject air into the diversion cavity 163 through the air injection pipe 162. The high-pressure gas in the diversion cavity 163 enters the rear end of the cavity of each inner support slider 157 through the diversion pipe 164, causing the pressure in the cavity of the inner support slider 157 to rise and push the sliding rod 166 to extend. The sliding rod 166 drives the locking tooth plate 167 and the miniature external tooth roller 157 to slide outward. 8. Surface micro-tooth interlocking; then, the servo sliding mechanism is controlled to drive the tracked inner support clamp and pre-assembled assembly to the top of the assembled semi-finished product, and the position of the pre-assembled assembly is adjusted so that its lower end is precisely aligned with the reserved wedge installation channel. At the same time, the servo electric downward pusher 171 is started to drive the downward push rod 172 to drive the intelligent flexible pressing head to press the pre-assembled assembly. When the flexible airbag 175 contacts the top of the pre-assembled assembly and establishes a stable contact pressure, the locking actuator is controlled to release the micro external tooth roller 158, so that the internal tooth belt 159 changes from the locked state to the free rolling state. Then the internal tooth belt 159 drives the pre-assembled assembly downward, and the wedge has no radial contact friction with the inner and outer ring raceways.During the press-fitting process of the intelligent flexible press-fitting head on the released pre-assembled assembly, the air pressure fluctuations within the flexible airbag 175 are monitored throughout by the air pressure sensor 176. Simultaneously, the air pressure sensing feedback system in the central control box 118 plots the pressure-displacement curve of the press-fitting process in real time. When a characteristic "pressure drop followed by recovery" waveform is detected on the curve, it is determined that the outer flange of the wedge retainer has successfully engaged in the annular groove of the bearing outer ring. The control system immediately stops the press-fitting action to ensure the consistency of the axial clearance. Finally, the second sealing ring is installed, completing the assembly.

Any person skilled in the art can modify the present invention or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of the present invention fall within the scope of protection claimed by the present invention.
