Description

Technical Field

[0001] This application relates to the field of material conveying and turning in machining, and in particular to an automatic feeding and turning device for turning the inner and outer circles of bearing rings. Background Technology

[0002] Bearing rings, as the core component of bearings, play a crucial 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, in the machining process of bearing rings, traditional internal and external turning often employs a step-by-step machining method. Generally, one end of the workpiece is clamped, and the other end is turned internally and externally. Then, the workpiece is flipped, the machined end is re-clamped, and the other end is turned internally and externally again. In this process, the ordinary flipping mechanism directly throws the bearing ring onto a hardened table when flipping it. However, this existing traditional machining method has significant drawbacks. The impact force generated by directly throwing the bearing ring onto the hardened table is relatively large, which easily causes impact damage to the bearing ring. Furthermore, the bearing ring is prone to displacement after placement, affecting the accuracy and efficiency of subsequent machining. Summary of the Invention

[0003] The purpose of this application is to overcome the above-mentioned technical problems and provide an automatic feeding and flipping device for turning the inner and outer diameters of bearing rings, including a worktable, and further comprising: A first flipping assembly is disposed at one end of the worktable; the first flipping assembly includes a base, a drive source, and a rotating arm; the rotating arm is rotatably disposed on one side of the base, and the drive source is used to drive the rotating arm to rotate; a clamping member is also connected to one end of the rotating arm, and the clamping member is used to clamp the bearing ring; The second flipping component has the same structure as the first flipping component and is located at the end of the worktable away from the first flipping component. It is used to clamp the bearing ring and flip it a second time. The first feeding assembly is located on one side of the first tilting assembly, and the first feeding assembly is used to feed the bearing rings onto the first tilting assembly; The second feeding assembly is located on one side of the second tilting assembly, and the second feeding assembly is used to feed the bearing rings onto the second tilting assembly; The first buffer platform is located on the side of the first tilting assembly away from the first feeding assembly; The second buffer platform is located on the side of the second flipping assembly away from the second feeding assembly.

[0004] By adopting the above technical solution, the first feeding assembly and the second feeding assembly can respectively convey the bearing rings to the first flipping assembly and the second flipping assembly. The first flipping assembly and the second flipping assembly flip the bearing rings twice, and the first buffer platform and the second buffer platform provide a buffer placement area for the flipped bearing rings. This enables automatic feeding and flipping of bearing rings, avoiding the impact damage and displacement problems caused by traditional flipping methods, and improving the processing quality and efficiency of bearing rings.

[0005] Preferably, the first buffer platform includes a support base, wherein the lower end of the support base is fixedly connected to the worktable; The upper end of the support base is provided with a placement platform, the top of the placement platform is provided with a stepped groove, and the lower end of the placement platform is provided with multiple vibration damping springs. One end of the vibration damping spring is fixedly connected to the support base, and the other end of the vibration damping spring is fixedly connected to the placement platform. The structure of the second buffer frame is the same as that of the first buffer frame.

[0006] By adopting the above technical solution, the support base is used to fix the placement platform, and a vibration damping spring is set at the lower end of the placement platform. Combined with the stepped groove opened at the top, the impact force on the bearing rings during placement can be reduced, impact damage can be avoided, and the displacement of the bearing rings after placement can be prevented.

[0007] Preferably, the worktable is provided with a CNC lathe on the side near the second feeding component; the CNC lathe is provided with a first feed port at the end near the first buffer table, wherein a first transfer mechanism is provided above the first feed port, and the first transfer mechanism is used to transfer the bearing ring from the first buffer table to the first feed port; The CNC lathe has a second feed port at one end near the second buffer table, and a second transfer mechanism is provided above the second feed port. The second transfer mechanism is used to transfer the bearing ring from the second buffer table to the second feed port.

[0008] By adopting the above technical solution, the bearing rings that have passed through the first and second buffer stands are respectively transferred to the first and second feed ports of the CNC lathe, enabling the flipped bearing rings to smoothly enter the CNC lathe for cutting and machining, thus improving the automation and continuity of the machining process. Preferably, one end of the rotating arm is connected to an "L"-shaped support plate, and the clamping component is fixed to the "L"-shaped support plate; The vertical end sidewall of the “L”-shaped support plate is provided with a movable groove, and a buffer block is provided in the movable groove; a support spring is provided between the buffer block and the movable groove, and a rubber pad is provided on the side of the buffer block away from the movable groove.

[0009] By adopting the above technical solution, the "L"-shaped support plate provides an installation base for the clamping component; the buffer block in the movable groove, together with the support spring and rubber pad, can play a buffering role during the clamping process of the bearing ring, reducing the impact damage to the bearing ring.

[0010] Preferably, the movable groove is equipped with a contact sensor, wherein the detection head of the contact sensor is spaced apart from the buffer block.

[0011] By adopting the above technical solution, during the process of the bearing ring contacting the buffer block and causing the buffer block to move into the movable groove under pressure, when the buffer block touches the detection head of the contact sensor due to external pressure, the contact sensor can send a signal to remind the staff of the relevant situation, so as to avoid damage to the bearing ring due to excessive pressure.

[0012] Preferably, a telescopic cylinder is provided below the horizontal end of the "L"-shaped support plate, wherein a buffer column is provided at the top of the piston rod of the telescopic cylinder, and the buffer column passes through the "L"-shaped support plate and is inserted upward into the bearing ring.

[0013] By adopting the above technical solution, the telescopic cylinder located below the horizontal end of the "L"-shaped support plate can drive the buffer column to move, so that the buffer column passes through the "L"-shaped support plate and is inserted upward into the bearing ring. This can further support and buffer the bearing ring, reduce the impact damage that may be caused to the bearing ring during the flipping process, and work with other components to realize automatic feeding and flipping of the bearing ring, avoid impact damage to the bearing ring and displacement after placement, and improve the processing efficiency and quality of the bearing ring.

[0014] Preferably, the upper inner wall of the stepped groove is provided with an elastic ball plunger, and the bottom of the upper end of the stepped groove is provided with a shock-absorbing pad.

[0015] By adopting the above technical solution, elastic ball-head plungers are installed on the inner walls of the upper ends of the stepped grooves of the first and second buffer platforms, which can position the bearing rings placed in the stepped grooves. Shock-absorbing pads are installed at the bottom of the upper ends of the stepped grooves to reduce the impact force on the bearing rings when they fall onto the buffer platforms, preventing impact damage. Combined with other structures of the automatic feeding and flipping device, automatic feeding and flipping functions are achieved, improving processing efficiency and product quality.

[0016] Preferably, the clamping component is configured as a pneumatic gripper, which includes a bidirectional clamping cylinder, a clamping plate, and an arc-shaped chuck. The clamping plates are fixedly connected to the piston rods at both ends of the bidirectional clamping cylinder, and the arc-shaped chuck is detachably connected to the side wall of the clamping plate.

[0017] By adopting the above technical solution, the pneumatic gripper can be used as a clamping component to flexibly control the clamping action of the bearing ring; the bidirectional clamping cylinder and the clamping plate can achieve stable bidirectional clamping; the arc-shaped chuck can be detachably connected to the side wall of the clamping plate, making it easy to replace the arc-shaped chuck of different specifications to adapt to bearing rings of different sizes.

[0018] Preferably, the workbench is further provided with a fall protection mechanism, which is located above the base; The fall protection mechanism includes a fall protection rail and a driving component. The fall protection rail includes a first arc-shaped rail segment and a second arc-shaped rail segment that are interconnected. The first arc-shaped rail segment and the second arc-shaped rail segment are connected. The second arc-shaped rail segment is located close to the first buffer platform. The driving component is used to drive the second arc-shaped rail segment to slide in a direction away from or close to the first arc-shaped rail segment. Each of the arc-shaped chucks has a limit rod fixed at one end. After the pneumatic gripper clamps the bearing ring, the two limit rods can slide simultaneously in the anti-fall groove. The anti-fall groove is used to prevent the two limit rods from moving away from each other.

[0019] By adopting the above technical solution, the anti-fall rail consists of a first arc-shaped rail section and a second arc-shaped rail section that are interconnected. The second arc-shaped rail section is close to the first buffer platform and can be driven to slide by the drive component. One end of the arc-shaped chuck is fixed with a limiting rod. After the pneumatic gripper holds the bearing ring, the rotating arm drives the pneumatic gripper to rotate. The two limiting rods on the pneumatic gripper can slide within the anti-fall rail. The anti-fall rail can prevent the two limiting rods from moving away from each other, even if the pneumatic gripper becomes loose during the gripping process. It can also prevent the bearing ring from accidentally falling off during the flipping process, improve the safety and stability of the first flipping assembly, and ensure that the bearing ring can be successfully loaded and flipped. After the first flipping assembly flips the bearing ring to the first buffer platform, the drive component drives the second arc-shaped rail section to move away from the first arc-shaped rail section. When the first material transfer mechanism transfers the bearing ring, it is not easy to interfere with the second arc-shaped rail section.

[0020] Preferably, two arc-shaped guide bars are connected at intervals at one end of the first arc-shaped track segment near the second arc-shaped track segment, and the distance between the two arc-shaped guide bars gradually increases in the direction closer to the second arc-shaped track segment.

[0021] By adopting the above technical solution, when the second arc-shaped rail section is still far away from the first arc-shaped rail section, the drive rotating arm is reset; the two arc-shaped guide bars facilitate the loosening of the two limit rods set opposite to each other on the starting gripper and slide into the first arc-shaped rail section, avoiding the limit rods from getting stuck, and ensuring that the anti-fall groove rail can play its normal anti-fall role for the bearing ring.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. This application uses a first flipping component and a second flipping component to flip the bearing rings. The first and second buffer frames can act as buffers, avoiding the traditional method of directly throwing the bearing rings onto a hard surface. This reduces the risk of impact damage to the bearing rings, reduces the impact force when the bearing rings are flipped and placed, and lowers the possibility of displacement. 2. The first feeding component and the second feeding component in this application respectively transport the bearing rings to one side of the corresponding flipping component, realizing automatic feeding and improving processing efficiency; 3. The anti-fall rail and limit rod in this application can prevent the two arc-shaped chucks on the pneumatic gripper from moving away from each other during the flipping process, prevent the bearing rings from falling off, and improve the stability of the device operation.

[0025] The specific implementation methods are described below with reference to the appendix. Figures 1 to 11 This application will be described in further detail.

[0026] Example 1: Reference Figure 1 The automatic feeding and flipping device for turning the inner and outer diameters of bearing rings 4 provided in this application embodiment includes a worktable 2, and further includes: CNC lathe 1 is fixed to one side of worktable 2. Worktable 2 serves as the basic support platform for the entire flipping device and is used to install and fix other components. The first feeding component 3 is fixed on the side of the worktable 2 away from the CNC lathe 1. The first feeding component 3 is responsible for conveying the bearing ring 4 to be processed from the storage area or the previous process to the starting point of the processing flow. During the feeding process, the bearing ring 4 is conveyed to the first flipping component 5 at a certain speed and in a certain order. The first flipping component 5 is located at the discharge end of the first feeding component 3. When the bearing ring 4 arrives, the first flipping component 5 clamps the bearing ring 4 and flips it for the first time. The purpose of flipping is to make one side of the bearing ring 4 face up so that it can be machined in the subsequent turning process. The first buffer platform 6 is located on the side of the first flipping assembly 5 away from the first feeding assembly 3, and provides a stable placement point for the flipped bearing ring 4; the first buffer platform 6 ensures that the bearing ring 4 remains stable during the clamping process, preventing the bearing ring 4 from moving or rotating, thereby ensuring the accuracy of subsequent processing. The second feeding assembly 7 is located on the side of the worktable 2 near the CNC lathe 1 and is used to feed the bearing ring 4 for the second time. The second feeding assembly 7 has the same structure as the first feeding assembly 3 but the feeding direction is opposite. The second feeding assembly 7 is responsible for feeding the bearing ring 4 after the first processing from the CNC lathe 1 back to the other side of the device to prepare for the second flipping and processing. The second flipping component 8 is located at the discharge end of the second feeding component 7 and is used to clamp the bearing ring 4 and flip it a second time. The second flipping component 8 has the same structure as the first flipping component 5. When the bearing ring 4 arrives, the second flipping component 8 clamps the bearing ring 4 and flips it a second time so that the other unprocessed surface of the bearing ring 4 faces upward so that it can be turned a second time. The second buffer table 9 is located 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 table 9 has the same structure as the first buffer table 6. The second buffer table 9 provides a stable placement point for the flipped bearing ring 4, ensuring that the bearing ring 4 remains stable during the clamping process and preventing movement or rotation, thereby ensuring the accuracy of subsequent processing. After the second flip, the bearing ring 4 is transported to the CNC lathe 1 for the second turning process. After processing, the bearing ring 4 can be gripped by the second material transfer 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 sent into the first feeding assembly 3 to start the next processing cycle.

[0027] Reference Figure 2As one embodiment of this application, the CNC lathe 1 has a first feed port 10 near the first buffer table 6, and a first transfer mechanism 11 is provided above the first feed port 10; the CNC lathe 1 has a second feed port 12 near the second buffer table 9, and a second transfer mechanism 13 is provided above the second feed port 12, and the second transfer mechanism 13 has the same structure as the first transfer mechanism 11; the first transfer mechanism 11 includes a first linear slide 1101, wherein the first linear slide 1101 is horizontally arranged... At the top of the worktable 2; one end of the first linear slide 1101 passes through the first feed port 10 and extends into the CNC lathe 1, while the other end of the first linear slide 1101 extends above the first buffer frame 6; a second linear slide 1102 is vertically mounted on the sliding seat of the first linear slide 1101, and a three-finger bidirectional clamping cylinder 1103 is fixedly mounted on the sliding seat of the second linear slide 1102. The three-finger bidirectional clamping cylinder 1103 is the core actuator of the material transfer mechanism, used to clamp and release the bearing ring 4.

[0028] In the above-described scheme, the CNC lathe 1 has a first feed port 10 at one end near the first buffer table 6 for receiving bearing rings 4 from the first buffer table 6; the CNC lathe 1 has a second feed port 12 at one end near the second buffer table 9 for receiving bearing rings 4 from the second buffer table 9; a first transfer mechanism 11 is provided above the first feed port 10, which is responsible for grabbing the bearing rings 4 from the first buffer table 6 and feeding them into the CNC lathe 1; a second transfer mechanism 13 is provided above the second feed port 12, which has the same structure as the first transfer mechanism 11, and is responsible for grabbing the bearing rings 4 from the second buffer table 9 and feeding them into the CNC lathe 1.

[0029] After the bearing race 4 is fixed on the first buffer table 6, the first material transfer mechanism 11 starts to work. 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 table 6. Then, the second linear slide 1102 moves vertically downward, so that the three-finger bidirectional clamping cylinder 1103 approaches and clamps the bearing race 4. After the three-finger bidirectional clamping cylinder 1103 clamps the bearing race 4, the second linear slide 1102 moves vertically upward, lifting the bearing race 4. Then, the first linear slide 1101 moves horizontally again, feeding the bearing race 4 into the CNC lathe 1 through the first feed port 10. After processing is completed in the CNC lathe 1, the first material transfer mechanism 11 repeats the gripping action to clamp the bearing race 4. The bearing ring 4, after its initial processing, is picked up and transferred to the feed end of the second feeding assembly 7. The second feeding assembly 7 then transports the bearing ring 4 from the CNC lathe 1 to the second flipping assembly 8. The second flipping assembly 8 clamps the bearing ring 4 and flips it a second time, so that the other unprocessed surface of the bearing ring 4 faces upward and is fixed on the second buffer table 9. The second transfer mechanism 13 then starts working. The working process of the second transfer mechanism 13 is the same as that of the first transfer 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 feed port 12 for a second turning process. After the second processing is completed in the CNC lathe 1, the second transfer mechanism 13 picks up the bearing ring 4 and places it in the unloading chute 29, thereby completing the automatic unloading of the bearing ring 4.

[0030] Please refer to the following: Figure 2 , Figure 3 As one embodiment of this application, the first feeding assembly 3 includes a belt conveyor 301, wherein two sets of gathering plates 302 are symmetrically arranged on the upper ends of both sides of the discharge end of the belt conveyor 301; the two sets of gathering plates 302 form a funnel-shaped structure, wherein a plurality of guide rollers 303 are arranged on the gathering plates 302 along their length direction.

[0031] In the above-described scheme, the belt conveyor 301, as the main part of the first feeding assembly 3, is primarily responsible for conveying the bearing rings 4 from the storage area or the previous process to the starting point of the processing flow. Two sets of gathering plates 302 are symmetrically arranged on the upper sides of the discharge end of the belt conveyor 301. These two sets of gathering plates 302, when combined, form a funnel-shaped structure. This design helps to concentrate the bearing rings 4 on the belt conveyor 301 into a smaller outlet area, reducing the likelihood of the bearing rings 4 scattering or shifting during conveying, and improving the accuracy and efficiency of the conveying process. Several guide rollers 303 are arranged along the length of the gathering plates 302. These guide rollers 303 provide additional guidance for the bearing rings 4, ensuring that the bearing rings 4 maintain a stable trajectory when passing through the gathering plates 302. The rolling nature of the guide rollers 303 reduces the friction between the bearing rings 4 and the gathering plates 302, lowering the conveying resistance of the bearing rings 4, thereby improving the smoothness and efficiency of the conveying process.

[0032] Please refer to the following: Figures 2 to 4 As one embodiment of this application, the first flipping component 5 includes a base 501, on which a drive source is fixedly installed, specifically a rotary cylinder 502; a rotary arm 503 is fixedly installed at the output end of the rotary cylinder 502, and an "L"-shaped support plate 504 is connected to the other end of the rotary arm 503; the "L"-shaped support plate 504 is disposed at the discharge end of the belt conveyor 301, and the height of the "L"-shaped support plate 504 is approximately equal 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 disposed on both sides of the rotary cylinder 502.

[0033] In the above scheme, the base 501 serves as the supporting structure of the first flipping component 5, providing a stable installation foundation for the entire component; the rotary cylinder 502 is the core power component of the first flipping component 5, and the rotary cylinder 502 can generate rotational motion through pneumatic means; the output end of the rotary cylinder 502 is fixedly connected to the rotary arm 503, and when the rotary cylinder 502 works, it will drive the rotary arm 503 to rotate; the other end of the rotary arm 503 is connected to an "L"-shaped support plate 504, so that the rotational motion of the rotary cylinder 502 can be transmitted to the "L"-shaped support plate 504 through the rotary arm 503; the "L"-shaped support plate 504 is set at the discharge end of the belt conveyor 301, and its height is equivalent to the height of the discharge end of the belt conveyor 301, which can ensure that the bearing ring 4 can be smoothly transferred from the belt conveyor 301 to the "L"-shaped support plate 504; when the rotary cylinder 502 works, the "L"-shaped support plate 504 will rotate together with the rotary arm 503, thereby realizing the flipping operation of the material.

[0034] Two electronic limit switches 505 are installed on the base 501, which are respectively set on both sides of the rotary cylinder 502. The electronic limit switches 505 are used to detect the rotational position of the rotary cylinder 502 driving the rotary arm 503 and the "L"-shaped support plate 504. When the rotary cylinder 502 drives the rotary arm 503 to rotate to a specific position, the corresponding electronic limit switch 505 will be triggered, thereby controlling the rotary cylinder 502 to stop and ensuring the accuracy and safety of the flipping operation.

[0035] Please refer to the following: Figures 5 to 7 As one embodiment of this application, a clamping component is fixed above the vertical end of the "L"-shaped support plate 504. Specifically, the clamping component is a pneumatic gripper, which includes a bidirectional clamping cylinder 506, a clamping plate 507, and an arc-shaped chuck 508. A clamping plate 507 is fixedly connected to the piston rods at both ends of the bidirectional clamping cylinder 506. Two arc-shaped chucks 508 are provided, each corresponding to one of the clamping plates 507. The arc-shaped chucks 508 are detachably connected to the sidewalls of the corresponding clamping plates 507 by bolts. A rubber anti-slip block 14 is fixed to the clamping surface of the arc-shaped chuck 508, and a pressure sensor 15 is installed inside the rubber anti-slip block 14. The front end of the arc-shaped chuck 508 is bent inward to block the bearing ring 4 conveyed by the belt conveyor 301.

[0036] 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 allows its clamping plate 507 to accurately align and clamp the bearing ring 4 conveyed 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; the inner side of the clamping plate 507 is provided with an arc-shaped chuck 508, which allows the clamping plate 507 to better adapt to the shape of the bearing ring 4 and provide a more stable clamping force; the outer wall of the arc-shaped chuck 508 is provided with a locking block 32, and the inner wall of the clamping plate 507 is provided with a limiting slot 5071 that matches the locking block 32, which facilitates the replacement of the appropriate arc-shaped chuck 508 according to the bearing ring 4 of different sizes.

[0037] The clamping surface of the arc-shaped chuck 508 is provided with a rubber anti-slip block 14, which increases the friction during clamping and prevents the bearing ring 4 from sliding or falling off during clamping. The rubber anti-slip block 14 is embedded with a pressure sensor 15, which can monitor the pressure changes during clamping in real time to ensure that the clamping force is stable enough without damaging the bearing ring 4. The synergistic effect of the rubber anti-slip block 14 and the pressure sensor 15 achieves stable clamping and blocking of the bearing ring 4, and has the advantages of adjustable clamping force, strong adaptability and reliable operation.

[0038] The front end of the arc-shaped chuck 508 bends inward, which serves as a blocking mechanism. When the bearing ring 4 is continuously conveyed from the belt conveyor 301 to the "L"-shaped support plate 504, once the foremost bearing ring 4 reaches the "L"-shaped support plate 504, the bidirectional clamping cylinder 506 is activated, causing the clamping plate 507 to retract. This causes the clamping plate 507 to clamp the arc-shaped chuck 508. During the movement of the arc-shaped chuck 508, the outer wall of the bent portion of the arc-shaped chuck 508 will contact the bearing ring 4 on the belt conveyor 301, preventing it from moving forward. This blocking design ensures that the bidirectional clamping cylinder 506 has sufficient time to clamp the bearing ring 4, avoiding collisions caused by excessive conveying speed, which could lead to clamping failure or the bearing ring 4 falling off.

[0039] Reference Figure 8 As one embodiment of this application, an movable groove 16 is provided 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.

[0040] In the above scheme, a movable groove 16 is provided on the inner side of the vertical end of the "L"-shaped support plate 504. 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, ensuring 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.

[0041] A support spring 18 is provided between the buffer block 17 and the movable groove 16. 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 is impacted and moves backward, the support spring 18 is compressed and stores energy. Once the impact force disappears, the support spring 18 releases energy and pushes the buffer block 17 back to its original position, ready to receive the next impact.

[0042] 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 off.

[0043] When the bearing ring 4 is conveyed from the belt conveyor 301 onto the "L"-shaped support plate 504, the bearing ring 4 will come into contact with 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, reducing 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 receive the next impact. Throughout the 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 conveying of the bearing ring 4.

[0044] Reference Figure 8 As one embodiment of this application, a contact sensor 20 is provided in the active slot 16, wherein the detection head of the contact sensor 20 is spaced apart from the buffer block 17.

[0045] In the above scheme, a contact sensor 20 is added in the movable slot 16. The detection head of the contact sensor 20 is installed in the movable slot 16 and maintains a certain distance from the buffer block 17. This distance is set according to the actual working requirements and the movement range of the buffer block 17. When the buffer block 17 is impacted by 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 this contact signal and convert it into an electrical signal for transmission. The electrical signal of the contact sensor 20 is sent to the industrial control computer 31. The industrial control computer 31 can determine the position of the bearing ring 4 based on the received signal, and then control the bidirectional clamping cylinder 506 to clamp and fix the bearing ring 4.

[0046] Please refer to the following: Figure 5 , Figure 6 and Figure 8 As one embodiment of this application, a telescopic cylinder 21 is provided below the horizontal end of the "L"-shaped support plate 504, wherein the telescopic cylinder 21 is fixedly connected to the "L"-shaped support plate 504 through the mounting bracket 22; an movable hole 23 is provided at the horizontal end of the "L"-shaped support plate 504, and a buffer column 24 is provided at the top of the piston rod of the telescopic cylinder 21; the buffer column 24 passes through the movable hole 23 and is inserted upward into the bearing ring 4, wherein the buffer column 24 passes through the bearing ring 4 and extends outward.

[0047] In the above-described scheme, the "L"-shaped support plate 504 has a horizontal end and a vertical end, and a telescopic cylinder 21 is fixedly installed below its horizontal end. The telescopic cylinder 21 is fixedly connected to the bottom of the "L"-shaped support plate 504 through the mounting bracket 22 to ensure that the cylinder can apply force stably when working. A movable hole 23 is opened on the horizontal end of the "L"-shaped support plate 504, and the design of the movable hole 23 allows the buffer column 24 to move up and down within it. A buffer column 24 is provided at the top of the piston rod of the telescopic cylinder 21, and the buffer column 24 is the part that directly contacts the bearing ring 4 when the telescopic cylinder 21 is in motion. The buffer column 24 passes through the movable hole 23 on the "L"-shaped support plate 504 and is inserted upward into the bearing ring 4. The buffer column 24 not only passes through the bearing ring 4, but also extends outward for a certain length, so that the buffer column 24 can have a certain range of action outside the bearing ring 4.

[0048] When the bearing ring 4 is conveyed from the belt conveyor 301 onto the "L"-shaped support plate 504, the bearing ring 4 will come into contact with 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 send it to the industrial control computer 31. At the same time, the industrial control computer 31 can determine the position of the bearing ring 4 based on the received signal, and then control the telescopic cylinder 21 to start. The telescopic cylinder 21 drives the piston rod to move the buffer column 24 upward and extend it upward by a certain length, which plays a buffering role after the bearing ring 4 flips, reducing impact and wear.

[0049] Reference Figure 9 As one embodiment of this application, the first buffer platform 6 includes a support base 601, wherein the lower end of the support base 601 is fixedly connected to the workbench 2; the upper end of the support base 601 is provided with a placement platform 602, wherein the placement platform 602 is movably connected to the support base 601; a stepped groove 603 is provided at the top of the placement platform 602, wherein the lower inner diameter of the stepped groove 603 is equivalent to the diameter of the buffer column 24, wherein the upper inner diameter of the stepped groove 603 is equivalent to the outer diameter of the bearing ring 4; an elastic ball plunger 25 is provided on the upper inner wall of the stepped groove 603, wherein a shock-absorbing pad 26 is provided at the bottom of the upper end of the stepped groove 603.

[0050] In the above-described scheme, the lower end of the support base 601 is fixedly connected to the worktable 2 to ensure the stability and accuracy of the first buffer frame 6 during operation; the upper end of the support base 601 is provided with a placement platform 602, which is movably connected to the support base 601, meaning that the placement platform 602 can be finely adjusted or modified within a certain range; a stepped groove 603 is provided at the top of the placement platform 602, which is a key part for placing and positioning the bearing ring 4. The lower inner diameter of the stepped groove 603 is approximately equal to the diameter of the buffer column 24, which ensures that the buffer column 24 can be tightly inserted into the lower end of the stepped groove 603, providing stable support and buffering for the bearing ring 4; the upper inner diameter of the stepped groove 603 is approximately equal to the outer diameter of the bearing ring 4, which allows the bearing ring 4 to be accurately placed into the upper end of the stepped groove 603, achieving precise positioning.

[0051] The upper inner wall of the stepped groove 603 is provided with an elastic ball plunger 25. The elastic ball plunger 25 has a certain elasticity and self-adaptability, and can automatically adjust its position and fit tightly against the inner wall of the bearing ring 4 when the bearing ring 4 is placed into the stepped groove 603, providing additional support and positioning. This design helps to reduce the shaking or displacement of the bearing ring 4 during the clamping process and improves the machining accuracy.

[0052] The upper bottom of the stepped groove 603 is provided with a shock-absorbing pad 26. The shock-absorbing pad 26 is usually made of soft materials, such as rubber or sponge, and has good shock absorption and buffering performance. 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, and protect the bearing ring 4 and the stepped groove 603 from damage.

[0053] Reference Figure 9 As one embodiment of this application, the lower end of the placement platform 602 is provided with a guide rod 604, wherein the support base 601 is provided with a limiting guide groove 605 adapted to the guide rod 604; the guide rod 604 is disposed in the limiting guide groove 605, wherein a gravity sensor (not shown in the figure) is installed at the bottom of the limiting guide groove 605; a plurality of damping springs 606 are provided along the circumference of the lower end of the placement platform 602, wherein the lower end of the damping spring 606 is fixedly connected to the support base 601, and the upper end of the damping spring 606 is fixedly connected to the placement platform 602.

[0054] In the above-described scheme, the lower end of the placement platform 602 is provided with a guide rod 604, which plays the role of guiding and stabilizing the movement of the placement platform 602; the support base 601 is provided with a limiting guide groove 605 that is adapted to the guide rod 604, and the guide rod 604 is set in the limiting guide groove 605. In this way, when the placement platform 602 moves up and down or makes fine adjustments, it can slide along the guide rod 604 in the limiting guide groove 605, ensuring the accuracy and stability of the movement.

[0055] 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 of the bearing ring 4 during placement, 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, which is then transmitted to the industrial control all-in-one computer 31. At the same time, the industrial control all-in-one computer determines the position of the bearing ring 4 on the placement platform 602 based on the received signal, and then controls the bidirectional clamping cylinder 506 to release the clamp on the bearing ring 4, ensuring the stability of the bearing ring 4 placement.

[0056] Multiple damping springs 606 are provided along the circumference of the lower end of the placement platform 602. The lower end of the damping spring 606 is fixedly connected to the support base 601, and the upper end is fixedly connected to the bottom of the placement platform 602, forming an elastic support system. When the placement platform 602 is subjected to impact or vibration, the damping spring 606 can absorb and mitigate these energies, thereby improving stability and durability.

[0057] Reference Figure 2 As one embodiment of this application, a cleaning nozzle 27 is provided above one side of the second buffer platform 9, wherein the cleaning nozzle 27 is fixedly connected to the workbench 2 via a fixed bracket 28; a material discharge chute 29 is provided on the side of the cleaning nozzle 27 away from the second buffer platform 9, wherein a material storage box 30 is provided at the discharge end of the material discharge chute 29.

[0058] In the above-described scheme, after the second buffer platform 9 completes the positioning of the bearing ring 4, the cleaning nozzle 27 starts to work. This positional design ensures that the cleaning nozzle 27 can evenly spray cleaning fluid onto the bearing ring 4 placed on the second buffer platform 9 to remove dirt, debris, or residue from its surface. The cleaning nozzle 27 is connected to an external liquid supply device through a pipeline. A feeding chute 29 is inclined on one side of the cleaning nozzle 27. The design of the feeding chute 29 allows the bearing ring 4 to be transferred to the feeding chute 29 by the second material transfer mechanism 13 after the CNC lathe 1 performs the second processing on the bearing ring 4. This allows the bearing ring 4 to slide smoothly along the feeding chute 29 to the discharge end and fall into the storage box 30.

[0059] Reference Figure 2 As one embodiment of this application, an industrial control all-in-one computer 31 is provided on one side of the workbench 2, wherein the industrial control all-in-one computer 31 is electrically connected to the first feeding component 3, the first flipping component 5, the first buffer platform 6, the first material transfer mechanism 11, the second feeding component 7, the second flipping component 8, the second buffer platform 9, and the second material transfer mechanism 13.

[0060] In the above-described solution, the industrial control all-in-one computer 31 is electrically connected to various mechanical components to realize information transmission and command issuance. The industrial control all-in-one computer 31 coordinates and controls the actions of each component according to a preset program or externally input commands. Simultaneously, the industrial control all-in-one computer 31 monitors the status and feedback information of each component to ensure the normal operation and timely adjustment of the entire system. Through the centralized control and coordination of the industrial control all-in-one computer 31, the entire automation system can achieve a high degree of automation and intelligence. Operators can easily monitor and manage the entire workflow through the interface of the industrial control all-in-one computer 31.

[0061] Example 2 The difference between this embodiment and Embodiment 1 is that: Reference Figure 10 and Figure 11 A fall prevention mechanism is added to the workbench 2. One end of the arc-shaped chuck 508 in each clamping component is fixed with a limit rod 34. The fall prevention mechanism is fixed above the base 501 inside the first flipping assembly 5.

[0062] In other embodiments, a fall protection mechanism may also be fixed above the base 501 inside both the first flip assembly 5 and the second flip assembly 8.

[0063] Reference Figure 11 The fall arrest mechanism includes a fall arrest rail 33 and a drive component 35. The fall arrest rail 33 includes a first arc-shaped rail segment 3301, a second arc-shaped rail segment 3302, and arc-shaped guide bars 3303. The first arc-shaped rail segment 3301 and the second arc-shaped rail segment 3302 are connected, and the second arc-shaped rail segment 3302 is positioned close to the first buffer platform 6. The first arc-shaped rail segment 3301 is fixed to the workbench 2 by a bracket. Two arc-shaped guide bars 3303 are fixed at intervals at one end of the first arc-shaped rail segment 3301 near the second arc-shaped rail segment 3302, forming a channel between the two arc-shaped guide bars 3303 for the second arc-shaped rail segment 3302 to pass through. The distance between the two arc-shaped guide bars 3303 gradually increases in the direction away from the first arc-shaped rail segment 3301.

[0064] Reference Figure 10 and Figure 11A linear slide module driven by a motor lead screw is fixed on the worktable 2. The driving component 35 is specifically set as the motor inside the linear slide module. A linkage bracket is fixed on the slide within the linear slide module, and the linkage bracket is fixedly connected to the second arc-shaped rail segment 3302. After the driving component 35 is started, it can drive the second arc-shaped rail segment 3302 to slide away from or towards the first arc-shaped rail segment 3301, so that the second arc-shaped rail segment 3302 is disconnected from or connected to the first arc-shaped rail segment 3301. When the pneumatic gripper holds the bearing ring 4, the two opposing limit rods 34 can slide in the anti-fall groove 33. The anti-fall groove 33 can prevent the two opposing limit rods 34 from moving away from each other. Therefore, if the gripper becomes loose during the rotation of the bearing ring 4 driven by the rotating arm 503, the limit rods 34 will slide in the anti-fall groove 33 to prevent the bearing ring 4 from falling. In addition, two arc-shaped guide bars 3303 are connected at intervals at one end of the first arc-shaped rail section 3301 near the second arc-shaped rail section 3302. The distance between the two arc-shaped guide bars 3303 gradually increases towards the second arc-shaped rail section 3302, which serves to guide the limiting rod 34 to re-enter the anti-fall groove rail 33.

[0065] The implementation principle of this embodiment is as follows: After the clamping member in the first flipping assembly 5 clamps the bearing ring 4, the rotating arm 503 drives the clamping member to rotate towards the first buffer platform 6; the two limiting rods 34 connected to the clamping member simultaneously slide into the anti-fall groove 33. The anti-fall groove 33 can prevent the two limiting rods 34 from moving away from each other, improving the safety and stability of the operation of the first flipping assembly 5, and ensuring that the bearing ring 4 can smoothly complete the feeding and flipping operation. After the first flipping assembly 5 flips the bearing ring 4 to the first buffer platform 6, the driving member 35 drives the second arc-shaped rail section 3302 to slide away from the first arc-shaped rail section 3301. When the first material transfer mechanism 11 transfers the bearing ring 4, it is not easy to interfere with the second arc-shaped rail section 3302. After the bearing ring 4 is lowered, the clamping member in the first flipping assembly 5 is rotated away from the first buffer platform 6 by the rotating arm 503. The clamping member moves between the two arc-shaped guide bars 3303, retracts under the action of the arc-shaped guide bars 3303, and slides into the first arc-shaped track segment 3301 along the arc-shaped guide bars 3303 until it returns to its original position. Subsequently, the driving member 35 drives the second arc-shaped track segment 3302 to move closer to the first arc-shaped track segment 3301, so that the second arc-shaped track segment 3302 is connected to the first arc-shaped track segment 3301 again.

[0066] In this embodiment, the cooperation between the anti-fall rail 33 and the limiting rod 34 provides additional safety for the bearing ring 4 during the flipping process. Even if the clamping parts become loose, the bearing ring 4 can be prevented from falling off, further improving the stability and reliability of the device.

[0067] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
