Description
Technical Field
[0001] This invention belongs to the field of bearing processing technology, and specifically relates to a machining lathe for motor bearings. Background Technology
[0002] As a core component of motor operation, the machining accuracy and quality of motor bearings directly affect the motor's operational stability, service life, and energy consumption. With the rapid development of new energy vehicles, high-end equipment manufacturing, and other fields, the market demand for motor bearings continues to grow, while also placing more stringent requirements on their dimensional accuracy, surface finish, structural strength, and other indicators.
[0003] Existing machining processes for the inner rings of motor bearings largely rely on traditional lathes or specialized machining equipment. Traditional machining equipment often uses manual feeding or semi-automatic conveying methods, which are not only inefficient but also prone to inaccurate blank positioning due to human error, affecting the accuracy of subsequent machining. Although some automated feeding mechanisms can achieve continuous feeding, they are difficult to adjust intermittently according to the processing rhythm, which can easily lead to material accumulation or supply interruption, reducing production continuity. Moreover, the machining of the inner rings of motor bearings involves multiple processes such as grinding, polishing, and grooving of the bottom, inner wall, and outer wall. Existing equipment often requires multiple single machines to complete the process step by step, or to achieve multiple processes by manually adjusting the blank posture on the same machine. This mode not only increases the equipment footprint and production costs, but also makes it difficult to guarantee machining accuracy due to positioning deviations during process transitions. At the same time, the poor coordination of multiple processes and low processing efficiency make it difficult to meet the needs of large-scale mass production. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a machining lathe for motor bearings.
[0005] The technical solution adopted to solve the above technical problems is: a machining lathe for motor bearings, including a machining body, two feed pipes are fixedly connected to the outer wall of the machining body, multiple blanks are rolledly connected inside the two feed pipes, and a feeding mechanism for intermittently conveying raw materials is provided at the front end of the two feed pipes.
[0006] A waste liquid collection and discharge assembly is installed at the bottom of the interior of the processing body. Two processing discs are fixedly connected to the inner wall of the processing body. A synchronization mechanism for synchronous processing is provided at the top center of the waste liquid collection and discharge assembly. A rotary clamping mechanism for clamping and flipping the blank is installed inside the synchronization mechanism.
[0007] The bottom of each of the two processing trays is respectively provided with a first processing mechanism and a second processing mechanism for processing the blanks, and the interior of the processing body is equipped with a conveying component for transporting the blanks.
[0008] Furthermore, the feeding mechanism includes a mounting box installed at the front end of the feed pipe. A fixing block is fixedly connected inside the mounting box. A drive motor is installed on the top of the fixing block. A cam is fixedly connected to the output end of the drive motor. A pawl is rotatably connected to the bottom of the fixing block. A spring is installed between the rear end of the pawl and the fixing block. A ratchet that meshes with the pawl is rotatably connected inside the mounting box. A support seat is installed on the top of the ratchet. A rotating block is rotatably connected to the top of the support seat. A connecting rod that passes through the interior of the support seat is installed between the rotating block and the ratchet. Multiple material-pulling rods are fixedly connected to the outer wall of the rotating block.
[0009] With the above technical solution, when the drive motor is running, its output end drives the cam to rotate. The cam periodically presses down on the front end of the pawl, causing the pawl to overcome the spring force and swing downward around the rotation point at the bottom of the fixed block. At this time, the engagement between the pawl and the ratchet is temporarily released. When the cam rotates to the non-pressing position, the spring's restoring force pushes the rear end of the pawl to swing upward, causing the front end of the pawl to re-engage with the teeth of the ratchet. Through this process, the pawl swings back and forth under the drive of the cam, thereby intermittently driving the ratchet to rotate in one direction. When the ratchet rotates, it drives the rotating block above the support to rotate synchronously through the connecting rod that runs through the support base. Multiple material-pulling rods on the outer wall of the rotating block rotate together with the rotating block, continuously feeding the raw material inside the feed pipe, realizing the intermittent and orderly conveying of materials.
[0010] Furthermore, the outer wall of the original blank slides between two adjacent feed bars.
[0011] The above technical solution ensures that the original blank is stably clamped by two adjacent feeding rods, ensuring that it moves synchronously with the feeding rods, avoiding deviation, falling or jamming during the conveying process, and guaranteeing the accuracy and stability of the feeding.
[0012] Furthermore, the synchronization mechanism includes a geared motor assembly installed on the top of the waste liquid collection and discharge assembly. A synchronization rod is fixedly connected to the output end of the geared motor assembly. Two rotating disks are fixedly connected to the outer wall of the synchronization rod. A positioning block is fixedly connected to the outer wall of each of the two rotating disks. A pad block and a transmission block are respectively installed inside the two processing disks.
[0013] With the above technical solution, when the geared motor assembly starts, its output end drives the synchronous rod to rotate, and the synchronous rod in turn drives the two rotating disks fixedly connected to the outer wall to rotate synchronously. As the rotating disks rotate, the positioning blocks on their outer walls also make circular motions. The positioning blocks will cooperate with the transmission blocks inside the two processing disks to realize the effective execution of subsequent processing steps.
[0014] Furthermore, the top of the positioning block is provided with a positioning hole corresponding to the blank, and the bottom of the positioning block is attached to the top of the pad block.
[0015] Through the above technical solution, the positioning hole at the top of the positioning block can accurately accommodate the blank, realize the precise positioning of the blank, and prevent it from shifting during synchronous transmission. The bottom of the positioning block fits into the top of the pad block, which helps it to be positioned better and does not affect subsequent movement.
[0016] Furthermore, the rotary clamping mechanism includes a rotary motor installed inside the positioning block. A transmission rod is installed at the output end of the rotary motor. A hollow threaded tube is slidably connected to the outer wall of the transmission rod. A tensioning motor is installed inside the positioning block near the hollow threaded tube. An adjusting gear that meshes with the hollow threaded tube is fixedly connected to the output end of the tensioning motor. A clamping box is fixedly connected to the other end of the transmission rod. A threaded rod is rotatably connected inside the clamping box. An adjusting threaded tube that meshes with the hollow threaded tube is installed near the middle position of the outer wall of the threaded rod. Clamping arms are slidably connected to the outer walls of the threaded rod near both ends.
[0017] With the above technical solution, when the blank needs to be clamped, the opening and closing motor starts, and its output end drives the adjusting gear to rotate. Since the adjusting gear meshes with the hollow threaded tube, it drives the hollow threaded tube to rotate. The hollow threaded tube then meshes with the adjusting threaded tube, thereby driving the threaded rod to rotate inside the clamping box. When the threaded rod rotates, the clamping arms at both ends of its outer wall slide along the threaded rod, moving closer or further apart to complete the clamping or releasing action of the blank. When the blank angle needs to be adjusted, the rotating motor starts, and its output end drives the transmission rod to rotate. The clamping box at the other end of the transmission rod will rotate accordingly. At the same time, since the transmission rod is slidably connected to the hollow threaded tube, it does not affect the clamping action controlled by the opening and closing motor, thereby realizing the rotation adjustment and stable clamping function of the blank.
[0018] Furthermore, the first processing mechanism includes a first arc-shaped box disposed inside the processing tray. The outer wall of the first arc-shaped box has multiple adjustment grooves. The inner wall of the first arc-shaped box is equipped with multiple first nozzles arranged in an array. A first arc-shaped plate is fixedly connected inside the first arc-shaped box. A waterproof cover is fixedly connected to the bottom of the first arc-shaped plate. A first motor is installed at the bottom of the first arc-shaped plate. Multiple transmission wheels are rotatably connected to the bottom of the first arc-shaped plate. A chain is installed between the multiple transmission wheels. A limiting wheel that restricts the position of the chain is rotatably connected to the bottom of the first arc-shaped plate. Two grinding discs, two polishing discs, a grinding column, and a polishing column are fixedly connected to the top of the multiple transmission wheels respectively. Multiple first drainage holes are opened at the top of the first arc-shaped plate.
[0019] With the above technical solution, when the first motor starts, its power is transmitted to multiple transmission wheels through the chain. Under the position restriction of the chain by the limit wheel, the transmission is stable. The multiple transmission wheels rotate accordingly, thereby driving the two grinding discs, two polishing discs, one grinding column and one polishing column connected to the top of the motor to rotate synchronously, realizing the grinding and polishing of the blank. Multiple first nozzles arranged in an array on the inner wall of the first arc-shaped box can spray the liquid required for processing to assist the processing. The waste liquid generated during processing will be discharged through multiple first drainage holes on the top of the first arc-shaped plate, while the waterproof cover can effectively protect the first motor and other bottom components from the influence of liquid.
[0020] Furthermore, the tops of the grinding disc and polishing disc are attached to the bottom of the corresponding blank, and the outer walls of the grinding column and polishing column are attached to the inner walls of the corresponding blank.
[0021] Through the above technical solution, the top of the grinding disc and the polishing disc are attached to the bottom of the blank, which can perform comprehensive and uniform grinding and polishing on the bottom of the blank, ensuring the processing accuracy of the bottom. The outer wall of the grinding column and the polishing column are attached to the inner wall of the blank, which can precisely act on the inner curved surface to achieve fine grinding and polishing of the inner wall. The two work together to process the bottom and inner wall of the blank at the same time, improving processing efficiency while ensuring consistent processing quality of each part, resulting in a better overall processing effect of the blank.
[0022] Furthermore, the second processing mechanism includes a fixed plate mounted on the top of the processing disk. A second motor is fixedly connected to the top of the fixed plate, and a drive wheel is mounted on the output end of the second motor. A rotating ring meshing with the drive wheel is rotatably connected to the top of the processing disk. A fixed seat is fixedly connected to the top of the rotating ring. An adjusting cylinder is mounted on the top of the fixed seat. A sliding block is slidably connected to the inner wall of the fixed seat. A connecting plate is fixedly connected inside the sliding block. A driving assembly is mounted on the top of the connecting plate. An internal support three-jaw chuck assembly is mounted on the output end of the driving assembly. A second arc-shaped box is installed inside the processing disk. A second arc-shaped plate is fixedly connected inside the second arc-shaped box. A grinding tube and a polishing tube are fixedly connected to the top of the second arc-shaped plate, respectively. Multiple second nozzles are evenly distributed on the top of the second arc-shaped plate. A control box is fixedly connected to the bottom of the second arc-shaped plate. A push-pull assembly is installed inside the control box. A slotting assembly is fixedly connected to the output end of the push-pull assembly. Multiple second drainage holes are opened on the top of the second arc-shaped plate.
[0023] Through the above technical solution, after the second motor starts, its output end drives the drive wheel to rotate. Since the drive wheel meshes with the rotating ring, it drives the rotating ring to rotate on the top of the processing plate. The fixed seat on the top of the rotating ring rotates synchronously with it. The adjusting cylinder can push the sliding block to slide along the inner wall of the fixed seat, and then drive the drive assembly and the inner support three-jaw chuck assembly to adjust their positions through the connecting plate. Under the drive of the drive assembly, the inner support three-jaw chuck assembly can firmly clamp the blank and drive it to rotate. At the same time, the grinding tube and polishing tube on the top of the second arc plate inside the second arc box will grind and polish its outer wall in coordination with the rotation of the blank. The second nozzle can spray processing auxiliary liquid to ensure processing effect and reduce dust. The push-pull assembly inside the control box can push the grooving assembly to extend and perform grooving processing on the blank. The waste liquid generated during processing is discharged through multiple second drainage holes on the top of the second arc plate, realizing the orderly progress of the processing process.
[0024] Furthermore, the processing body is internally equipped with multiple connecting pipes, which are installed between the second drain hole and the waste liquid collection and discharge assembly.
[0025] Through the above technical solution, the connecting pipe connects the second drain hole to the waste liquid collection and discharge component, which can quickly and directionally transport the waste liquid generated by the second processing mechanism to the waste liquid collection and discharge component, and then collect and discharge it uniformly.
[0026] The beneficial effects of the present invention are as follows: (1) The present invention designs a feeding mechanism, and through the coordinated cooperation of the drive motor, cam, pawl, spring and ratchet, the continuous rotation of the motor is cleverly transformed into the intermittent unidirectional rotation of the ratchet, thereby driving the rotating block and the feeding rod to achieve intermittent feeding action, and accurately realizes the intermittent conveying of the blank, which not only avoids material accumulation and congestion, but also provides an orderly material supply rhythm for subsequent synchronous processing, rotating clamping and other links, ensuring the continuity and coordination of the entire processing process; (2) The present invention designs a rotating clamping mechanism and a first processing mechanism. The rotating clamping mechanism, with the linkage of the opening and closing motor, adjusting gear, hollow threaded tube and other components, can achieve stable clamping of the blank through the clamping arm. At the same time, under the drive of the rotating motor, the clamping box and the blank are flexibly rotated by the transmission rod, which can accurately adjust the angle of the blank, ensuring that its bottom and inner wall can be accurately aligned with the processing parts of the first processing mechanism. The rotating clamping mechanism provides a stable and angle-adjustable processing reference for the first processing mechanism, ensuring the processing of the blank. The working parts are closely fitted to the blank to be processed, improving the processing accuracy and uniformity. The flexible adjustment capability of the rotating clamping mechanism enables the first processing mechanism to adapt to the processing needs of blanks of different specifications, enhancing the versatility of the equipment; (3) The present invention designs a second processing mechanism, which drives the fixed seat and clamping components to rotate synchronously through the meshing transmission of the second motor, drive wheel and rotating ring. With the help of the adjusting cylinder, the sliding block is pushed to adjust the position, so that the inner support three-jaw chuck assembly can flexibly adapt to blanks in different positions, realize stable clamping and rotation drive, and provide a stable and adjustable attitude reference for the processing of the outer wall of the blank. The grinding tube and polishing tube on the top of the second arc plate cooperate with the rotation of the blank, and can perform all-round and uniform grinding and polishing on the outer wall of the blank. The push-pull component in the control box drives the grooving component to extend, and can complete the grooving processing simultaneously. It realizes the integrated processing of multiple processes such as outer wall grinding, polishing and grooving, greatly shortens the processing process and improves the overall processing efficiency. The rotating ring rotates in conjunction with the transmission block to transmit the processed blank. Attached Figure Description

Detailed Implementation
[0046] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0047] like Figure 1 - Figure 5 As shown, a machining lathe for motor bearings in this embodiment includes a machining body 1. Two feed pipes 2 are fixedly connected to the outer wall of the machining body 1, and multiple blanks 3 are rolledly connected inside the two feed pipes 2.
[0048] like Figure 5 and Figure 6As shown, each of the two feed pipes 2 is equipped with a feeding mechanism 4 for intermittently conveying raw materials. The feeding mechanism 4 includes a mounting box 401 installed at the front end of the feed pipe 2. A fixing block 402 is fixedly connected inside the mounting box 401. A drive motor 403 is installed on the top of the fixing block 402. A cam 404 is fixedly connected to the output end of the drive motor 403. A pawl 405 is rotatably connected to the bottom of the fixing block 402. A spring 406 is installed between the rear end of the pawl 405 and the fixing block 402. A ratchet 4 that meshes with the pawl 405 is rotatably connected inside the mounting box 401. 07. A support base 408 is installed on the top of the ratchet 407. A rotating block 409 is rotatably connected to the top of the support base 408. A connecting rod that passes through the inside of the support base 408 is installed between the rotating block 409 and the ratchet 407. Multiple feeding rods 410 are fixedly connected to the outer wall of the rotating block 409. The outer wall of the blank 3 slides between two adjacent feeding rods 410, so that the blank 3 is stably clamped by the two adjacent feeding rods 410, ensuring that it moves synchronously with the feeding rods 410, avoiding deviation, falling or jamming during the conveying process, and ensuring the accuracy and stability of the feeding.
[0049] like Figure 5 and Figure 6 As shown, when the drive motor 403 is running, its output end drives the cam 404 to rotate. The cam 404 periodically presses down on the front end of the pawl 405, causing the pawl 405 to swing downwards around the rotation point at the bottom of the fixed block 402 against the elastic force of the spring 406. At this time, the engagement between the pawl 405 and the ratchet 407 is temporarily released. When the cam 404 rotates to the non-pressing position, the restoring force of the spring 406 pushes the rear end of the pawl 405 upwards, causing the front end of the pawl 405 to re-engage with the ratchet 407. The toothed engagement of 07 allows the pawl 405 to reciprocate under the drive of the cam 404, thereby intermittently driving the ratchet 407 to rotate in one direction. When the ratchet 407 rotates, it drives the rotating block 409 above the support 408 to rotate synchronously through the connecting rod that runs through the support 408. Multiple material-pulling rods 410 on the outer wall of the rotating block 409 rotate together with the rotating block 409, continuously feeding the raw material 3 inside the feed pipe 2, thus achieving intermittent and orderly material conveying.
[0050] like Figure 3 As shown, a waste liquid collection and discharge assembly 5 is installed at the bottom of the interior of the processing body 1, and two processing discs 6 are fixedly connected to the inner wall of the processing body 1.
[0051] like Figure 7 - Figure 10As shown, a synchronization mechanism 7 for synchronous processing is provided at the top center of the waste liquid collection and discharge assembly 5. The synchronization mechanism 7 includes a geared motor assembly 701 installed on the top of the waste liquid collection and discharge assembly 5. A synchronization rod 702 is fixedly connected to the output end of the geared motor assembly 701. Two rotating disks 703 are fixedly connected to the outer wall of the synchronization rod 702. Positioning blocks 704 are fixedly connected to the outer walls of the two rotating disks 703. The top of the positioning block 704 is provided with a positioning hole corresponding to the blank 3, and the bottom of the positioning block 704 is attached to the top of the pad block 705. The positioning hole at the top of the positioning block 704 can accurately accommodate the blank 3, realize the precise positioning of the blank 3, and prevent it from shifting during synchronous transmission. The bottom of the positioning block 704 is attached to the top of the pad block 705 to help it be positioned better without affecting subsequent movement. The pad block 705 and the transmission block 706 are respectively installed inside the two processing disks 6.
[0052] like Figure 7 - Figure 10 As shown, when the geared motor assembly 701 is started, its output end drives the synchronizing rod 702 to rotate. The synchronizing rod 702 then drives the two rotating disks 703 fixedly connected to the outer wall to rotate synchronously. As the rotating disks 703 rotate, the positioning block 704 on its outer wall also makes a circular motion. The positioning block 704 will cooperate with the transmission block 706 inside the two processing disks 6 to realize the effective execution of subsequent processing steps.
[0053] like Figure 11 and Figure 12 As shown, the synchronous mechanism 7 is equipped with a rotary clamping mechanism 8 for clamping and flipping the blank 3. The rotary clamping mechanism 8 includes a rotary motor 801 installed inside the positioning block 704. A transmission rod 802 is installed at the output end of the rotary motor 801. A hollow threaded tube 803 is slidably connected to the outer wall of the transmission rod 802. A tensioning motor 804 is installed inside the positioning block 704 near the hollow threaded tube 803. An adjusting gear 805 that meshes with the hollow threaded tube 803 is fixedly connected to the output end of the tensioning motor 804. A clamping box 806 is fixedly connected to the other end of the transmission rod 802. A threaded rod 807 is rotatably connected inside the clamping box 806. An adjusting threaded tube 808 that meshes with the hollow threaded tube 803 is installed near the middle position of the outer wall of the threaded rod 807. Clamping arms 809 are slidably connected to the outer walls of the threaded rod 807 near both ends.
[0054] like Figure 11 and Figure 12As shown, when the blank 3 needs to be clamped, the opening and closing motor 804 starts, and its output end drives the adjusting gear 805 to rotate. Since the adjusting gear 805 meshes with the hollow threaded tube 803, it drives the hollow threaded tube 803 to rotate. The hollow threaded tube 803 meshes with the adjusting threaded tube 808, which in turn drives the threaded rod 807 to rotate in the clamping box 806. When the threaded rod 807 rotates, the clamping arms 809 at both ends of its outer wall slide along the threaded rod 807, moving closer or further apart to complete the clamping or releasing action of the blank 3. When the angle of the blank 3 needs to be adjusted, the rotating motor 801 starts, and its output end drives the transmission rod 802 to rotate. The clamping box 806 at the other end of the transmission rod 802 will rotate accordingly. At the same time, since the transmission rod 802 is slidably connected to the hollow threaded tube 803, it does not affect the clamping action controlled by the opening and closing motor 804, thereby realizing the rotation adjustment and stable clamping function of the blank 3.
[0055] like Figure 13 and Figure 14 As shown, each of the two processing discs 6 has a first processing mechanism 9 for processing the blank 3 at its bottom. The first processing mechanism 9 includes a first arc-shaped box 901 disposed inside the processing disc 6. The outer wall of the first arc-shaped box 901 has multiple adjustment grooves 902. The inner wall of the first arc-shaped box 901 is equipped with multiple first nozzles 903 arranged in an array. A first arc-shaped plate 904 is fixedly connected inside the first arc-shaped box 901. A waterproof cover 905 is fixedly connected to the bottom of the first arc-shaped plate 904. A first motor 906 is installed at the bottom of the first arc-shaped plate 904. Multiple transmission wheels 907 are rotatably connected to the bottom of the first arc-shaped plate 904. A chain 908 is installed between the multiple transmission wheels 907. A limiting wheel 909 that limits the position of the chain 908 is rotatably connected to the bottom of the first arc-shaped plate 904. The tops of the multiple transmission wheels 907 are respectively fixedly connected to... The assembly includes two grinding discs 910, two polishing discs 911, one grinding column 912, and one polishing column 913. The tops of the grinding discs 910 and 911 are attached to the bottom of the corresponding blank 3, while the outer walls of the grinding column 912 and 913 are attached to the inner walls of the corresponding blank 3. The tops of the grinding discs 910 and 911 are attached to the bottom of the blank 3, enabling comprehensive and uniform grinding and polishing of the bottom of the blank 3, ensuring the bottom processing accuracy. The outer walls of the grinding column 912 and 913 are attached to the inner walls of the blank 3, allowing precise application to the curved surface of the inner wall, achieving fine grinding and polishing of the inner wall. The two components work together to process the bottom and inner wall of the blank 3 simultaneously, improving processing efficiency while ensuring consistent processing quality across all parts, resulting in a better overall processing effect for the blank 3. The top of the first arc-shaped plate 904 has multiple first drainage holes 914.
[0056] like Figure 13 and Figure 14As shown, when the first motor 906 starts, its power is transmitted to multiple transmission wheels 907 through the chain 908. Under the position restriction of the chain 908 by the limit wheel 909, the transmission is stable. The multiple transmission wheels 907 rotate accordingly, thereby driving the two grinding discs 910, two polishing discs 911, one grinding column 912 and one polishing column 913 connected to their tops to rotate synchronously, realizing the grinding and polishing of the blank 3. Multiple first nozzles 903 arranged in an array on the inner wall of the first arc-shaped box 901 can spray out the liquid required for processing to assist the processing. The waste liquid generated during processing will be discharged through multiple first drainage holes 914 on the top of the first arc-shaped plate 904, while the waterproof cover 905 can effectively protect the first motor 906 and other bottom components from the influence of liquid.
[0057] like Figure 15 - Figure 18 As shown, each of the two processing disks 6 has a second processing mechanism 10 for processing the blank 3 at its bottom. The second processing mechanism 10 includes a fixed plate 1001 mounted on the top of the processing disk 6, a second motor 1002 fixedly connected to the top of the fixed plate 1001, a drive wheel 1003 mounted on the output end of the second motor 1002, a rotating ring 1004 rotatably connected to the top of the processing disk 6 and meshing with the drive wheel 1003, a fixed seat 1005 fixedly connected to the top of the rotating ring 1004, an adjusting cylinder 1006 mounted on the top of the fixed seat 1005, a sliding block 1007 slidably connected to the inner wall of the fixed seat 1005, a connecting plate 1008 fixedly connected inside the sliding block 1007, a drive assembly 1009 mounted on the top of the connecting plate 1008, an internal support three-jaw chuck assembly 1010 mounted on the output end of the drive assembly 1009, a second arc-shaped box 1011 mounted inside the processing disk 6, and a second arc-shaped... The top of the second arc-shaped plate 1012 is fixedly connected to a grinding tube 1013 and a polishing tube 1014, respectively. Multiple second nozzles 1015 are distributed on the top of the second arc-shaped plate 1012. A control box 1016 is fixedly connected to the bottom of the second arc-shaped plate 1012. A push-pull assembly 1017 is installed inside the control box 1016. A slotting assembly 1018 is fixedly connected to the output end of the push-pull assembly 1017. Multiple second drainage holes 1019 are opened on the top of the second arc-shaped plate 1012. Multiple connecting pipes are installed inside the processing body 1. The connecting pipes are installed between the second drainage holes 1019 and the waste liquid collection and discharge assembly 5. The connecting pipes connect the second drainage holes 1019 and the waste liquid collection and discharge assembly 5, which can quickly and directionally transport the waste liquid generated by the second processing mechanism 10 to the waste liquid collection and discharge assembly 5, and then collect and discharge it uniformly. A conveying assembly 11 for conveying the blank 3 is installed inside the processing body 1.
[0058] like Figure 15 - Figure 18 As shown, after the second motor 1002 starts, its output end drives the drive wheel 1003 to rotate. Since the drive wheel 1003 meshes with the rotating ring 1004, it drives the rotating ring 1004 to rotate on the top of the processing disk 6. The fixed seat 1005 on the top of the rotating ring 1004 rotates synchronously with it. The adjusting cylinder 1006 can push the sliding block 1007 to slide along the inner wall of the fixed seat 1005, and then drive the drive assembly 1009 and the inner support three-jaw chuck assembly 1010 to adjust their positions through the connecting plate 1008. Under the drive of the drive assembly 1009, the inner support three-jaw chuck assembly 1010 can process the blank 3. The blank 3 is firmly clamped and rotated. At the same time, the grinding tube 1013 and polishing tube 1014 on the top of the second arc plate 1012 inside the second arc box 1011 will grind and polish its outer wall in conjunction with the rotation of the blank 3. The second nozzle 1015 can spray processing auxiliary liquid to ensure processing effect and reduce dust. The push-pull component 1017 inside the control box 1016 can push the grooving component 1018 to extend and perform grooving processing on the blank 3. The waste liquid generated during processing is discharged through multiple second drainage holes 1019 on the top of the second arc plate 1012 to achieve orderly processing.
[0059] The working principle of this embodiment is as follows: the two feed pipes 2 intermittently convey the inner ring blank 3 of the bearing under the action of the feeding mechanism 4. The drive motor 403 drives the cam 404 to rotate. The cam 404 periodically presses the front end of the pawl 405, causing it to overcome the elastic force of the spring 406 and swing down to disengage from the ratchet 407. When the cam 404 rotates to the non-pressing position, the spring 406 resets and pushes the front end of the pawl 405 to re-engage with the ratchet 407. The reciprocating swing of the pawl 405 intermittently pushes the ratchet 407 to rotate in one direction. The ratchet 407 drives the rotating block 409 to rotate through the connecting rod. The material-pulling rod 410 on its outer wall rotates together. Since the outer wall of the blank 3 slides between the two adjacent material-pulling rods 410, the blank 3 is stably clamped and moves synchronously with the material-pulling rod 410, realizing orderly conveying to the synchronization mechanism 7.
[0060] When the blank 3 is detected to be pushed to the top of the pad 705, the clamping component of the rotary clamping mechanism 8 starts to work. The opening and closing motor 804 drives the adjusting gear 805 to rotate, driving the hollow threaded tube 803 to rotate. In turn, the adjusting threaded tube 808 drives the threaded rod 807 to rotate, causing the clamping arm 809 to slide along the threaded rod 807 to clamp the blank 3. After the blank 3 is clamped, the reduction motor assembly 701 of the synchronization mechanism 7 starts, driving the synchronization rod 702 and the two rotating disks 703 to rotate. The positioning block 704 on the outer wall of the rotating disk 703 moves in a circular motion. As the rotating disk 703 continues to move, it moves until it reaches the first processing area. Then, the first motor 906 starts, and the power is transmitted to multiple transmission wheels 907 via the chain 908. Under the limiting action of the limiting wheel 909, the transmission wheels 907 drive the top grinding disc 910, polishing disc 911, grinding column 912 and polishing column 913 to rotate. The first grinding disc 910 and polishing disc 911 first grind and polish the bottom of the blank 3. After the bottom processing is completed, the rotating disc 703 continues to rotate. When it moves to the position of the first adjusting groove 902, the processing disc 6 and the first arc-shaped box 901 have enough space to support the rotation of the clamping components of the rotating clamping mechanism 8. The rotating motor 801 drives the transmission rod 802 and the clamping components to rotate. The box 806 rotates. Because the transmission rod 802 is slidably connected to the hollow threaded tube 803, it does not affect the clamping action, realizing the flipping of the blank 3. As the rotating disk 703 rotates, the blank 3 is brought to the position of the second grinding disk 910 and polishing disk 911. The second grinding disk 910 and polishing disk 911 grind and polish the top of the blank 3. After the processing of the top of the blank 3 is completed, the rotating disk 703 continues to rotate the blank 3. When it moves to the position of the second adjusting groove 902, the rotating clamping mechanism 8 continues to rotate the blank 3, so that the blank 3 is sleeved on the grinding column 912, and the grinding column 912 grinds the inner ring surface of the blank 3. After the grinding process is completed, the rotating disk 703 continues to rotate with the blank 3 and the rotating clamping mechanism 8 rotates synchronously, so that the blank 3 flips out of the grinding column 912 position. With the synchronous operation of the rotating disk 703 and the rotating clamping mechanism 8, the blank 3 flips and fits into the polishing column 913 to polish the inner ring surface of the blank 3. After completing this series of processing work, the rotating disk 703 and the rotating clamping mechanism 8 rotate synchronously again to drive the blank 3 to disengage from the polishing column 913. When the rotating clamping mechanism 8 drives the blank 3 to rotate to the horizontal, the rotating clamping mechanism 8 will stop operating, and the rotating disk 703 will drive the blank 3 to move towards the second processing mechanism 10.
[0061] When the rotating disk 703 drives the blank 3 to the initial position of the second processing mechanism 10, the adjusting cylinder 1006 pushes the sliding block 1007 to slide. The position of the drive assembly 1009 and the inner support three-jaw chuck assembly 1010 is adjusted by the connecting plate 1008. Under the action of the drive assembly 1009, the inner support three-jaw chuck assembly 1010 clamps the blank 3 and drives it to rotate. The second motor 1002 drives the drive wheel 1003 to rotate, driving the rotating ring 1004 and the fixed seat 1005 that mesh with it to rotate, controlling the movement of the blank 3. The grinding tube 1013 and polishing tube 1014 on the top of the second arc plate 1012 work together with the rotation of the blank 3 to polish the outer wall. During processing, the second nozzle 1015 sprays auxiliary liquid, and the push-pull component 1017 in the control box 1016 pushes the grooving component 1018 to extend and complete the grooving process. After the overall processing is completed, the second motor 1002 continues to drive the rotating ring 1004 and the fixed seat 1005 to rotate until the blank 3 held by the inner support three-jaw chuck component 1010 reaches above the transfer block 706. At this time, the inner support three-jaw chuck component 1010 stops holding the blank 3 in the inner support, and the blank 3 falls onto the transfer component 11 under the action of gravity. The transfer component 11 transports the blank 3 out, and the waste liquid generated during processing is transported to the waste liquid collection and discharge component 5 through the connecting pipe for unified collection and discharge.
