[0002] As the core component of bearings, bearing rings play a vital role in the mechanical field. With the continuous development of industry, the requirements for bearing precision, service life, and overall performance are becoming increasingly stringent, and the machining quality of bearing rings directly determines these key indicators. Currently, traditional internal and external turning of bearing rings is often performed in a step-by-step process. Typically, one end of the workpiece is clamped, and internal and external turning operations are performed on the other end. The workpiece is then flipped, the machined end is re-clamped, and internal and external turning operations are continued on the other end. During this process, the conventional flipping mechanism used to flip the bearing rings directly onto a hard surface. However, this existing traditional machining method has significant drawbacks. The impact force generated by the conventional flipping mechanism directly onto the hard surface can easily damage the bearing rings. Furthermore, the bearing rings are prone to shifting after placement, affecting the accuracy and efficiency of subsequent machining. Summary of the Invention

The second arc-shaped rail section is close to the first buffer stand and can be driven to slide by a driving member. The limit rod is fixed at one end of the arc-shaped chuck. After the pneumatic clamp grips the bearing ring, the rotating arm drives the pneumatic clamp to rotate. The two limit rods on the pneumatic clamp can slide in the anti-fall groove. The anti-fall groove can prevent the two limit rods from moving away from each other, even if the pneumatic clamp becomes loose during the clamping process. It can also prevent the bearing ring from accidentally falling off during the flipping process, improve the safety and stability of the operation of the first flipping component, and ensure that the bearing ring can successfully complete the loading and flipping operations. After the first flipping assembly flips the bearing ring to the first buffer stand, the driving member drives the second curved rail section to move away from the first curved rail section, so that when the first material transfer mechanism transfers the bearing ring, it is not easy to interfere with the second curved rail section. Preferably, two curved guide bars are connected to one end of the first curved rail section close to the second curved rail section, and the distance between the two curved guide bars gradually increases towards the direction close to the second curved rail section.

The second turning assembly 8 is provided at the discharge end of the second feeding assembly 7 and is used to clamp the bearing ring 4 and perform a second turning on it. The second turning assembly 8 has the same structure as the first turning assembly 5. When the bearing ring 4 arrives, the second turning assembly 8 clamps the bearing ring 4 and performs a second turning on it, so that the other unprocessed surface of the bearing ring 4 faces upward, so as to facilitate the second turning process. The second buffer stand 9 is arranged on the side of the second flipping assembly 8 away from the second feeding assembly 7, and is used to fix the bearing ring 4 for the second time; the second buffer stand 9 has the same structure as the first buffer stand 6, wherein the second buffer stand 9 provides a stable placement position for the flipped bearing ring 4, ensuring that the bearing ring 4 remains stable during the clamping process to prevent movement or rotation, thereby ensuring the subsequent processing accuracy; the bearing ring 4 after the second flip is transported to the CNC lathe 1 for a second turning process, and after the processing is completed, the bearing ring 4 can be grabbed by the second material moving mechanism 13 and placed in the unloading chute 29 to complete the unloading of the bearing ring 4; at the same time, the new bearing ring 4 to be processed is fed into the first feeding assembly 3 to start the next processing cycle.

[0013] In the above-described scheme, a first feed port 10 is provided at one end of the CNC lathe 1 close to the first buffer platform 6, for receiving the bearing ring 4 from the first buffer platform 6; a second feed port 12 is provided at one end of the CNC lathe 1 close to the second buffer platform 9, for receiving the bearing ring 4 from the second buffer platform 9; a first material transfer mechanism 11 is provided above the first feed port 10, which is responsible for grabbing the bearing ring 4 from the first buffer platform 6 and sending it into the CNC lathe 1; a second material transfer mechanism 13 is provided above the second feed port 12, and its structure is the same as that of the first material transfer mechanism 11, which is responsible for grabbing the bearing ring 4 from the second buffer platform 9 and sending it into the CNC lathe 1.

[0014] When the bearing ring 4 is fixed on the first buffer platform 6, the first material moving mechanism 11 starts to work, wherein the first linear slide 1101 drives the second linear slide 1102 and the three-finger bidirectional clamping cylinder 1103 to move horizontally above the first buffer platform 6, and then the second linear slide 1102 moves vertically downward, so that the three-finger bidirectional clamping cylinder 1103 approaches and clamps the bearing ring 4. After the three-finger bidirectional clamping cylinder 1103 clamps the bearing ring 4, the second linear slide 1102 moves vertically upward to lift the bearing ring 4; then the first linear slide 1101 moves horizontally again to feed the bearing ring 4 into the CNC lathe 1 through the first feed port 10; after completing the processing in the CNC lathe 1, the first material moving mechanism 11 repeats the grabbing action to clamp the bearing ring 4 It is taken and transferred to the feed end of the second feeding assembly 7, and the bearing ring 4 after the first processing is transported from the CNC lathe 1 to the second flipping assembly 8 through the second feeding assembly 7. The second flipping assembly 8 clamps the bearing ring 4 and flips it for a second time, so that the other unprocessed surface of the bearing ring 4 faces up and is fixed on the second buffer table 9; the second material moving mechanism 13 starts to work, wherein the working process of the second material moving mechanism 13 is the same as that of the first material moving mechanism 11, except that it processes the bearing ring 4 on the second buffer table 9, and feeds it into the CNC lathe 1 through the second feeding port 12 for the second turning process; after completing the second processing in the CNC lathe 1, the second material moving mechanism 13 grabs the bearing ring 4 and places it in the unloading chute 29, thereby completing the automatic unloading of the bearing ring 4.

[0015] Please refer to Figure 2 、 Figure 3 As an embodiment of the present application, the first feeding component 3 includes a belt conveyor 301, wherein two groups of bunching plates 302 are symmetrically provided on the upper ends of both sides of the discharge end of the belt conveyor 301; the two groups of bunching plates 302 form a funnel-shaped structure, wherein the bunching plates 302 are provided with a plurality of guide rollers 303 along their length direction.

[0016] In the above-mentioned scheme, the belt conveyor 301 serves as the main part of the first feeding component 3, and is mainly responsible for conveying the bearing rings 4 from the storage area or the previous process to the starting point of the processing flow; two groups of bunching plates 302 are symmetrically arranged at the upper ends on both sides of the discharge end of the belt conveyor 301, wherein the two groups of bunching plates 302 are combined together to form a funnel-shaped structure. This design helps to concentrate the bearing rings 4 on the belt conveyor 301 to a smaller outlet area, thereby reducing the scattering or deviation of the bearing rings 4 during the conveying process, and improving the accuracy and efficiency of the conveying; by arranging a number of guide rollers 303 on the bunching plate 302 along its length direction, the function of these guide rollers 303 is to provide additional guidance for the bearing rings 4, ensuring that the bearing rings 4 can maintain a stable motion trajectory when passing through the bunching plate 302; the rolling nature of the guide rollers 303 reduces the friction between the bearing rings 4 and the bunching plate 302, reduces the conveying resistance of the bearing rings 4, and thus improves the smoothness and efficiency of the conveying.

[0017] Please refer to Figures 2 to 4 As an embodiment of the present application, the first flip component 5 includes a base 501, wherein a driving source is fixedly installed on the base 501, and the driving source is specifically a rotating cylinder 502; a rotating arm 503 is fixedly installed on the output end of the rotating cylinder 502, wherein the other end of the rotating arm 503 is connected to an "L"-shaped support plate 504; the "L"-shaped support plate 504 is arranged at the discharge end of the belt conveyor 301, wherein the height of the "L"-shaped support plate 504 is equivalent to the height of the discharge end of the belt conveyor 301; an electronic limit switch 505 is installed on the base 501, wherein two electronic limit switches 505 are provided, and are respectively arranged on both sides of the rotating cylinder 502.

[0018] When the rotating cylinder 502 is working, the "L"-shaped support plate 504 will rotate with the rotating arm 503, thereby realizing the flipping operation of the material.

[0019] Two electronic limit switches 505 are installed on the base 501, which are respectively arranged on both sides of the rotating cylinder 502. The electronic limit switch 505 is used to detect the rotation position of the rotating arm 503 and the "L"-shaped support plate 504 driven by the rotating cylinder 502. When the rotating cylinder 502 drives the rotating arm 503 to rotate to a specific position, the corresponding electronic limit switch 505 will be triggered, thereby controlling the stop of the rotating cylinder 502 to ensure the accuracy and safety of the flipping operation.

[0020] Please refer to Figures 5 to 7 As one embodiment of the present application, a clamping member is fixed above the vertical end of the "L"-shaped support plate 504. The clamping member is specifically a pneumatic clamping jaw, which includes a bidirectional clamping cylinder 506, a clamping plate 507, and an arc-shaped clamping head 508. A clamping plate 507 is fixedly connected to the piston rod at each end of the bidirectional clamping cylinder 506. Two arc-shaped clamping heads 508 are provided, corresponding one to each clamping plate 507. The arc-shaped clamping heads 508 are detachably connected to the side walls of the corresponding clamping plates 507 by bolts. A rubber anti-slip block 14 is fixed to the clamping surface of the arc-shaped clamping head 508, wherein the rubber anti-slip block 14 is internally provided with a pressure sensor 15. The front end of the arc-shaped clamping head 508 is bent inward to block the bearing ring 4 transported by the belt conveyor 301.

[0021] In the above scheme, a bidirectional clamping cylinder 506 is fixed above the vertical end of the "L"-shaped support plate 504, which can simultaneously control the movement of the piston rods at both ends; the position setting of the bidirectional clamping cylinder 506 enables its clamping plate 507 to accurately align with and clamp the bearing ring 4 transported from the belt conveyor 301; clamping plates 507 are fixedly connected to the piston rods at both ends of the bidirectional clamping cylinder 506, and these clamping plates 507 are the main components for performing the clamping action; an arc-shaped clamping head 508 is provided on the inner side of the clamping plate 507. This design enables the clamping plate 507 to better adapt to the shape of the bearing ring 4 and provide a more stable clamping force; a clamping block 32 is provided on the outer wall of the arc-shaped clamping head 508, wherein a limit slot 5071 adapted to the clamping block 32 is opened on the inner wall of the clamping plate 507, which is convenient for replacing the appropriate arc-shaped clamping head 508 according to bearing rings 4 of different sizes.

[0022] A rubber anti-sliding block 14 is provided on the clamping surface of the arc-shaped clamping head 508, wherein the anti-sliding block increases the friction during clamping to prevent the bearing ring 4 from sliding or falling off during the clamping process; pressure sensors 15 are embedded inside the rubber anti-sliding block 14, which can monitor the pressure changes during the clamping process in real time to ensure that the clamping force is sufficiently stable without damaging the bearing ring 4; the synergistic effect of the rubber anti-sliding block 14 and the pressure sensor 15 realizes stable clamping and blocking of the bearing ring 4, and has the advantages of adjustable clamping force, strong adaptability, and reliable operation.

[0023] The front end of the arc-shaped clamp 508 is bent inward, and this design acts as a barrier. When the bearing ring 4 is continuously transported from the belt conveyor 301 to the "L"-shaped support plate 504, when the front end of the bearing ring 4 moves to the "L"-shaped support plate 504, the bidirectional clamping cylinder 506 starts to drive the clamping plate 507 to contract, so that the clamping plate 507 drives the arc-shaped clamp 508 to clamp the bearing ring 4; in the process of the movement of the arc-shaped clamp 508, the outer wall of the bent part of the arc-shaped clamp 508 will contact the bearing ring 4 on the belt conveyor 301 and prevent it from moving forward; this blocking design ensures that the bidirectional clamping cylinder 506 has enough time to clamp the bearing ring 4, avoiding the congestion and collision of the bearing ring 4 due to excessive conveying speed, which in turn leads to clamping failure or the bearing ring 4 falling off.

[0024] Reference Figure 8 As an embodiment of the present application, a movable groove 16 is opened on the inner side of the vertical end of the "L"-shaped support plate 504, wherein a buffer block 17 is provided in the movable groove 16; a support spring 18 is provided between the buffer block 17 and the movable groove 16, wherein a rubber pad 19 is provided on the side of the buffer block 17 away from the movable groove 16.

[0025] In the above scheme, a movable groove 16 is opened on the inner side of the vertical end of the "L"-shaped support plate 504, wherein the design of the movable groove 16 provides space for the installation and movement of the buffer block 17; the shape and size of the movable groove 16 are determined according to the needs of the buffer block 17 to ensure that the buffer block 17 can move freely in the groove but will not fall off; the buffer block 17 is installed in the movable groove 16 to absorb and buffer the impact force from the bearing ring 4; when the bearing ring 4 contacts the buffer block 17, the buffer block 17 will be subjected to pressure and move backward, thereby playing a buffering role and reducing the direct impact between the buffer block 17 and the "L"-shaped support plate 504.

[0026] A support spring 18 is provided between the buffer block 17 and the movable groove 16, wherein one end of the support spring 18 is connected to the buffer block 17, and the other end is fixed to the side wall of the movable groove 16; the support spring 18 provides a restoring force for the buffer block 17. When the buffer block 17 moves backward under impact, the support spring 18 will be compressed and store energy; once the impact force disappears, the support spring 18 will release energy and push the buffer block 17 back to its original position, ready for the next impact.

[0027] A rubber pad 19 is provided on the side of the buffer block 17 away from the movable groove 16. The rubber pad 19 has good elasticity and wear resistance. The function of the rubber pad 19 is to further reduce noise and vibration during impact, while protecting the bearing ring 4 and the buffer block 17 itself from damage; the rubber pad 19 can also provide additional friction to help stabilize the bearing ring 4 and prevent it from sliding or falling.

[0028] When the bearing ring 4 is conveyed from the belt conveyor 301 to the "L"-shaped support plate 504, the bearing ring 4 will contact the buffer block 17. After being impacted, the buffer block 17 will move backward, compressing the support spring 18. At the same time, the rubber pad 19 will absorb part of the impact force to reduce noise and vibration; once the impact force disappears, the support spring 18 will push the buffer block 17 back to its original position, ready to meet the next impact; during the whole process, the buffer block 17 and the rubber pad 19 work together to protect the support plate and the bearing ring 4 from damage, while ensuring the stable transportation of the bearing ring 4.

[0029] Reference Figure 8 As an embodiment of the present application, a contact sensor 20 is provided in the movable groove 16 , wherein the detection head of the contact sensor 20 is spaced apart from the buffer block 17 .

[0030] In the above scheme, a contact sensor 20 is added in the movable groove 16, wherein the detection head of the contact sensor 20 is installed in the movable groove 16 and maintains a certain distance from the buffer block 17. This distance is set according to actual working requirements and the moving range of the buffer block 17; when the buffer block 17 is affected by the impact force of the bearing ring 4 and moves backward, the buffer block 17 will gradually approach the detection head of the contact sensor 20; once the buffer block 17 contacts the detection head of the contact sensor 20, the contact sensor 20 will immediately detect the contact signal and convert it into an electrical signal for transmission; the electrical signal of the contact sensor 20 is transmitted to the industrial control all-in-one computer 31, and the industrial control all-in-one computer 31 can judge the position status of the bearing ring 4 based on the received signal, and then control the bidirectional clamping cylinder 506 to start clamping and fixing the bearing ring 4 through the industrial control all-in-one computer 31.

The buffer column 24 not only passes through the bearing ring 4, but also extends outward to a certain length, so that the buffer column 24 can have a certain range of action outside the bearing ring 4.

[0033] When the bearing ring 4 is conveyed from the belt conveyor 301 to the "L"-shaped support plate 504, the bearing ring 4 will contact the buffer block 17. After being impacted, the buffer block 17 will move backward and compress the support spring 18, so that the buffer block 17 will gradually approach the detection head of the contact sensor 20; once the buffer block 17 contacts the detection head of the contact sensor 20, the contact sensor 20 will immediately detect this contact signal, convert it into an electrical signal and transmit it to the industrial control all-in-one computer 31; at the same time, the industrial control all-in-one computer 31 can judge the position status of the bearing ring 4 based on the received signal, and then control the telescopic cylinder 21 to start, and drive the piston rod through the telescopic cylinder 21 to drive the buffer column 24 to move upward, and extend upward a certain length, which plays a buffering role for the bearing ring 4 after flipping, reducing impact and wear.

[0036] An elastic ball plunger 25 is provided on the inner wall of the upper end of the stepped groove 603. The elastic ball plunger 25 has a certain elasticity and adaptability. When the bearing ring 4 is placed in the stepped groove 603, it can automatically adjust its position and fit tightly against the inner wall of the bearing ring 4, providing additional support and positioning. This design helps to reduce the shaking or deviation of the bearing ring 4 during the clamping process, thereby improving the processing accuracy.

[0037] A shock-absorbing pad 26 is provided at the bottom of the upper end of the stepped groove 603. The shock-absorbing pad 26 is usually made of soft materials, such as rubber or sponge, and has good shock absorption and buffering properties. When the bearing ring 4 is placed in the stepped groove 603, the shock-absorbing pad 26 can absorb and alleviate the impact force on the bearing ring 4, protecting the bearing ring 4 and the stepped groove 603 from damage.

[0040] By installing a gravity sensor at the bottom of the limiting guide groove 605, when the placement platform 602 is subjected to the impact force when the bearing ring 4 is placed, the guide rod 604 will apply pressure to the gravity sensor. The gravity sensor can detect this gravity change in real time and convert it into an electrical signal and transmit it to the industrial control all-in-one machine 31; at the same time, the industrial control and all-in-one machine judge the position status of the bearing ring 4 on the placement platform 602 based on the received signal, and then control the bidirectional clamping cylinder 506 to loosen the clamping of the bearing ring 4, thereby ensuring the stability of the placement of the bearing ring 4.

[0046] Example 2

[0047] The difference between this embodiment and embodiment 1 is that: Reference Figure 10 and Figure 11 An anti-falling mechanism is additionally provided on the workbench 2 , and one end of the arc-shaped clamp 508 in each clamping member is fixed with a limit rod 34 , and the anti-falling mechanism is fixed above the base 501 in the first flip assembly 5 .

[0048] In other embodiments, an anti-falling mechanism may be fixed above the base 501 in both the first flip assembly 5 and the second flip assembly 8 .

[0049] Reference Figure 11 The anti-fall mechanism includes an anti-fall groove 33 and a drive member 35. The anti-fall groove 33 includes a first curved rail section 3301, a second curved rail section 3302, and a curved guide bar 3303. The first curved rail section 3301 and the second curved rail section 3302 are connectable, and the second curved rail section 3302 is positioned adjacent to the first buffer platform 6. The first curved rail section 3301 is secured to the workbench 2 via a bracket. Two curved guide bars 3303 are fixed at intervals at one end of the first curved rail section 3301 near the second curved rail section 3302. A passage is formed between the two curved guide bars 3303 for the second curved rail section 3302 to pass through. The distance between the two curved guide bars 3303 gradually increases as it moves away from the first curved rail section 3301.

[0050] Reference Figure 10 and Figure 11, a linear slide module driven by a motor screw is fixed on the workbench 2, and the driving component 35 is specifically set as a motor in the linear slide module. A linkage bracket is fixed on the slide in the linear slide module, and the linkage bracket is fixedly connected to the second arc rail segment 3302. After the driving component 35 is started, it can drive the second arc rail segment 3302 to slide in a direction away from or close to the first arc rail segment 3301, so that the second arc rail segment 3302 is disconnected or connected with the first arc rail segment 3301. When the pneumatic clamp clamps the bearing ring 4, the two relative limit rods 34 can slide in the anti-fall groove rail 33, and the anti-fall groove rail 33 can prevent the two relative limit rods 34 from moving away from each other, so that in the process of the rotating arm 503 driving the bearing ring 4 to rotate, if the clamp becomes loose, the limit rod 34 will slide in the anti-fall groove rail 33 to prevent the bearing ring 4 from falling. In addition, two arc guide bars 3303 are spaced apart and connected to one end of the first arc rail segment 3301 close to the second arc rail segment 3302, and the distance between the two arc guide bars 3303 gradually increases toward the direction close to the second arc rail segment 3302, thereby guiding the limit rod 34 to re-enter the anti-fall groove rail 33.

[0051] The operating principle of this embodiment is as follows: after the clamping member within the first flipping assembly 5 clamps the bearing ring 4, the rotating arm 503 drives the clamping member to rotate toward the first buffer platform 6; the two limit rods 34 connected to the clamping member simultaneously slide into the anti-falling groove 33, which prevents the two limit rods 34 from moving away from each other, thereby improving the safety and stability of the operation of the first flipping assembly 5 and ensuring the smooth completion of the loading and turning operations of the bearing ring 4. After the first flipping assembly 5 flips the bearing ring 4 onto the first buffer platform 6, the driving member 35 drives the second curved rail segment 3302 to slide away from the first curved rail segment 3301, making it less likely to interfere with the second curved rail segment 3302 when the first material transfer mechanism 11 transfers the bearing ring 4. After the clamping member in the first flip assembly 5 lowers the bearing ring 4, the rotating arm 503 drives the clamping member to rotate away from the first buffer platform 6. The clamping member moves between the two curved guide bars 3303, where it is pulled together and slides along the curved guide bars 3303 into the first curved track segment 3301 until it returns to its original position. Subsequently, the driving member 35 drives the second curved track segment 3302 toward the first curved track segment 3301, reconnecting the second curved track segment 3302 to the first curved track segment 3301.

[0052] In this embodiment, the cooperation of the anti-fall groove rail 33 and the limit rod 34 provides additional safety protection for the bearing ring 4 during the flipping process. Even if the clamping part becomes loose, it can prevent the bearing ring 4 from falling, further improving the stability and reliability of the device.

[0053] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
