Description

Technical Field

[0001] This invention relates to the technical field of bearing manufacturing and processing, specifically to a bearing ring distribution device. Background Technology

[0002] Bearings are a crucial component in modern mechanical equipment. They primarily support rotating shafts or other moving bodies, guide rotational or tactile motion, and bear loads transmitted from the main shaft or parts on the shaft. The inner and outer rings are important components of the bearing races.

[0003] In the production process of bearing rings, the inner and outer rings first need to undergo grinding. Currently, the main processing method for bearing rings is to use an automated conveyor line for grinding, which connects all grinding equipment in the order of processing. This allows the bearing rings to be automatically transported to the next grinding equipment after the previous process is completed. However, during the production of bearing rings, the production time required for different processes varies. Therefore, processes with short production times often require only one station, while processes with long production times require two stations. This arrangement is necessary to ensure the smooth operation of the entire production line. When transporting bearing rings from the station with short production times to the station with long production times, workers usually need to collect the rings from one production line and then move them to the two different stations. This results in heavy workload for workers and low production efficiency. Therefore, a new technical solution is needed to solve the above technical problems. Summary of the Invention

[0004] This application proposes a bearing ring distribution device. By setting a quantitative distribution device on the main conveyor belt, the bearing rings on the main conveyor belt are evenly distributed to two branch conveyor belts. The uniform distribution is achieved by using a mechanical structure, eliminating the need for manual collection and transportation to different next workstations, thereby reducing the labor intensity of workers and improving production efficiency.

[0005] Therefore, this application provides a bearing ring distribution device, including a main conveyor belt for receiving the rings processed at the previous station, a branch conveyor belt for conveying the rings to the next station, and a quantitative distribution device between the main conveyor belt and the branch conveyor belt. There are two branch conveyor belts, and both branch conveyor belts are connected to the quantitative distribution device. The quantitative distribution device is used to evenly distribute the rings from the main conveyor belt to the two branch conveyor belts. The quantitative distribution device is provided with a frame for supporting the quantitative distribution device. The quantitative distribution device includes a distribution box for receiving the main conveyor belt rings, a discharge pipe for conveying to the branch conveyor belt, a push block slidably disposed in the distribution box, and a drive device for driving the push block to slide. The distribution box is perpendicular to the main conveyor belt and spans across the end of the main conveyor belt near the branch conveyor belt. There are two discharge pipes, both of which are fixedly connected to the distribution box. The ends of the two discharge pipes away from the distribution box are respectively connected to a branch conveyor belt. The drive device drives the push block to reciprocate periodically, thereby pushing the rings received in the distribution box to be distributed into the two discharge pipes.

[0006] By adopting the above technical solution: the quantitative distribution device is supported by a frame and positioned at the junction of the main conveyor belt and the branch conveyor belt; when the main conveyor belt moves the rings into the distribution box, the drive device drives the push block to slide within the distribution box, causing the push block to push the rings in the distribution box to fall into the discharge pipe. The rings then fall along the discharge pipe onto the branch conveyor belt. As the drive device reciprocates periodically, it drives the push block to reciprocate within the distribution box, thus evenly distributing the rings entering the distribution box into the two discharge pipes. This results in the rings being evenly distributed along the discharge pipes to the two branch conveyor belts. By using a mechanical structure for even distribution, manual collection and transport to different workstations are no longer required, achieving the goal of reducing labor intensity and improving production efficiency.

[0007] Preferably, the driving device includes a mounting shell fixed on the frame, a rack slidably connected to the mounting shell, a connecting rod connecting the rack and the push block, a drive gear for driving the rack to slide, and a driving component fixed on the frame. Two racks are provided and symmetrically arranged on both sides of the drive gear. Each rack is connected to a connecting rod, and both connecting rods are fixedly connected to the push block. The driving component is connected to the drive gear to drive the drive gear to rotate and mesh with the two racks respectively.

[0008] By adopting the above technical solution: the driving component drives the driving gear to rotate inside the mounting housing. Since the driving gear meshes with two racks respectively, and the two racks are evenly slidably connected to the mounting housing, the driving gear drives the two symmetrical racks to slide back and forth inside the mounting housing. Since the two racks are fixedly connected to the push block through two connecting rods, the two racks drive the push block to slide back and forth, that is, the push block performs periodic reciprocating motion inside the dispensing box.

[0009] Preferably, a sliding assembly is provided between the rack and the mounting housing. The sliding assembly includes a groove formed on the side wall of the mounting housing and a slider fixedly connected to the rack. The slider is located in the groove and is slidably connected to the groove.

[0010] By adopting the above technical solution: when the drive gear drives the rack to slide in the mounting shell, since the rack is fixedly connected to the slider and the slider is slidably connected to the groove, the rack drives the slider to slide in the groove. By using the groove to constrain the slider, the sliding direction of the rack can be determined, and the rack can be supported to ensure that the rack and the drive gear are in the same horizontal plane, so that the two can mesh better and the drive gear drives the rack to move.

[0011] Preferably, the device also includes a material feeding device for controlling the passage of material on the main conveyor belt. The material feeding device includes a sliding block slidably connected to the frame, a mounting plate fixedly connected to the frame, a pressing block fixedly connected to the sliding block, and a pressing rod connected to the pressing block. There are two pressing rods, both of which are slidably connected to the mounting plate. Each pressing rod is connected to a pressing block. Both pressing blocks are fixedly connected to the sliding block. The slider drives the pressing block to reciprocate to push the two pressing rods to descend alternately. The blocking collar moves with the conveyor belt. The sliding block is provided with a reciprocating device for driving the sliding block to slide back and forth.

[0012] By adopting the above technical solution: when the ferrule slides on the main conveyor belt, the reciprocating device drives the sliding block to slide back and forth. The sliding block drives the two lower pressure blocks to slide back and forth. When the two lower pressure blocks slide back and forth, they drive the two connected lower pressure rods to slide alternately. This causes the lower pressure rods to lower and block the ferrule from moving on the conveyor belt. When the lower pressure rod on the side away from the quantitative distribution device descends, the ferrule, along with the main conveyor belt, comes into contact with the lower pressure rod near the quantitative distribution device. At this time, as the sliding block slides, the lower pressure rod on the side near the quantitative distribution device gradually rises, and the lower pressure rod on the side away from the quantitative distribution device gradually descends, thus affecting the subsequent movement of the ferrule. The continuous obstruction of the lowering rings ensures that only one ring remains between the two lowering rods. As the lowering rod closest to the quantitative distribution device rises to its highest point, it no longer obstructs the ring from moving with the main conveyor belt. This causes the main conveyor belt to pull the ring away from the area between the two lowering rods, allowing each ring to slide into the discharge pipe. A discharge device is then installed to discharge the rings one by one, preventing them from accumulating at the distribution box. When the pusher slides, it moves the rings that have not yet entered the distribution box, causing them to fall off the main conveyor belt and into a location outside the main conveyor, resulting in damage or contamination.

[0013] Preferably, the pressing rod abuts against the sliding block, and a reset device is provided between the pressing rod and the mounting plate. The reset device includes a positioning ring fixedly connected to the pressing rod and an elastic element disposed between the positioning ring and the mounting plate. The elastic element is sleeved on the outside of the pressing rod and is used to push the pressing rod to always abut against the pressing block. The two ends of the elastic element are fixedly connected to the positioning ring and the mounting plate, respectively.

[0014] By adopting the above technical solution: when the pressing block pushes the pressing rod downward, the pressing rod drives the positioning ring to slide downward. Since the elastic element is sleeved on the outside of the pressing rod, the pressing rod drives the positioning ring to compress the elastic element. When the pressing block slides in the opposite direction, the pressing block releases the pressure applied to the pressing rod. At this time, the elastic element applies an upward elastic force to the positioning ring. The elastic element drives the pressing rod to abut against the pressing block through the positioning ring. Since the pressing rod abuts against the sliding block, after the pressing block pushes the pressing rod down, the elastic element needs to be used to push the pressing rod upward to ensure that the pressing rod always abuts against the pressing block.

[0015] Preferably, a rolling device is provided between the pressing rod and the pressing block. The rolling device includes an abutment block fixedly connected to the pressing rod and a roller rotatably disposed in the abutment block. The circumferential sidewall of the roller is provided with a groove, and the roller abuts against the pressing block and the pressing block is located in the groove of the roller.

[0016] By adopting the above technical solution: since the pressure rod abuts against the pressure block and the pressure rod is slidably connected to the mounting plate, the pressure block drives the roller to rotate inside the mounting block when it slides. Furthermore, a groove is opened on the circumferential side wall of the roller, so that a "rail and groove" limiting relationship is formed between the roller and the pressure block, thereby improving the stability of the connection between the pressure block and the pressure rod, and changing the sliding friction force into rolling friction force, reducing the wear of the pressure block.

[0017] Preferably, each of the lower pressure rods is provided with an anti-deviation device at the end away from the lower pressure block to prevent the bearing from deviating when it is blocked. The anti-deviation device includes a mounting block fixedly connected to the lower pressure rod and a blocking pin for blocking the movement of the bearing. There are two blocking pins, which are symmetrically arranged along the axis of the main conveyor belt and fixedly connected to the mounting block. The two blocking pins abut against two positions on the outside of the bearing respectively.

[0018] By adopting the above technical solution: Since the ferrule is a circular structure, when only one pressure bar is used to abut against the ferrule, the ferrule is easily colliding with subsequent ferrules, causing it to slide at the pressure bar and slide off the main conveyor belt. After setting up the anti-deviation device, when the ferrule abuts against two blocking pins, the two blocking pins block two positions of the ferrule, improving the stability of the ferrule after it is blocked and avoiding the possibility of the ferrule deviating from the main conveyor belt after being blocked.

[0019] Preferably, a support groove for supporting the sliding block is provided between the sliding block and the frame. The support groove is sleeved on the outside of the sliding block and is fixedly connected to the frame. A waist-shaped groove for allowing the lower pressure block to slide is provided on the side of the support groove away from the frame.

[0020] By adopting the above technical solution: since the lifting groove is fixedly connected to the frame, the sliding block is located in the lifting groove, and the lifting groove supports the sliding block, so that the sliding block slides in the lifting groove.

[0021] Preferably, the reciprocating device includes a rotating shaft rotatably connected to the frame, a turntable fixedly connected to the rotating shaft, a drive rod fixedly connected to the sliding block, a guide block fixedly connected to the frame, and a connecting rod connecting the drive rod and the turntable. The two ends of the connecting rod are rotatably connected to the drive rod and the turntable, respectively. The guide block has a through hole that allows the drive rod to slide to guide the sliding direction of the drive rod. A linkage device is provided between the rotating shaft and the drive component.

[0022] By adopting the above technical solution: the driving component drives the rotating shaft to rotate through the linkage device, the rotating shaft drives the turntable to rotate, the turntable drives the connecting rod to rotate with the turntable. Since the connecting rod is rotatably connected to both the turntable and the driving rod, and the turntable drives one end of the connecting rod to make a circular motion when it rotates, the connecting rod drives the driving rod to slide along the direction constrained by the guide block, thereby causing the driving rod to drive the sliding block to reciprocate.

[0023] Preferably, the linkage device includes a driving gear fixedly connected to the output shaft of the driving component, a driven gear fixedly connected to the rotating shaft, and a chain connecting the driving gear and the driven gear. The chain is used to synchronize the rotation of the driving gear and the driven gear.

[0024] By adopting the above technical solution: the output shaft of the drive component drives the active gear to rotate, and the active gear drives the driven gear to rotate through the chain. Since the driven gear is fixedly connected to the rotating shaft, the driven gear drives the rotating shaft to rotate, and the rotating shaft drives the turntable to rotate. By setting a linkage device, the feeding device and the quantitative distribution device are linked to ensure that the feeding device feeds one ring and the quantitative distribution device distributes one ring, thereby avoiding the accumulation of rings at the distribution box, which would cause the rings to fall from the main conveyor belt to places other than the branch conveyor, resulting in damage or contamination of the rings.

[0025] The working principle and beneficial effects of this application are as follows: 1. By installing a quantitative distribution device at the junction of the main conveyor belt and the two branch conveyor belts, when the main conveyor belt drives the rings to move into the distribution box, the drive device drives the push block to slide in the distribution box, causing the push block to push the rings in the distribution box to fall into the discharge pipe. The rings fall along the discharge pipe onto the branch conveyor belts. With the periodic reciprocating motion of the drive device, the push block reciprocates in the distribution box, thus the push block evenly distributes the rings entering the distribution box into the two discharge pipes, thereby making the rings evenly distributed along the discharge pipes to the two branch conveyor belts. The mechanical structure is used for even distribution, eliminating the need for manual collection and transportation to different workstations, thus reducing the labor intensity of workers and improving production efficiency.

[0026] 2. By installing a feeding device on the main conveyor belt, the quantitative distribution device is fed one by one. When the ring slides on the main conveyor belt, the reciprocating device drives the sliding block to slide back and forth. The sliding block drives the two lower pressure blocks to slide back and forth. When the two lower pressure blocks slide back and forth, they drive the two connected lower pressure rods to slide alternately. When the lower pressure rods descend, they block the ring from moving on the conveyor belt. When the lower pressure rod on the side away from the quantitative distribution device descends, the ring abuts against the lower pressure rod near the quantitative distribution device along with the main conveyor belt. At this time, as the sliding block slides, the lower pressure rod on the side near the quantitative distribution device gradually rises, and the lower pressure rod on the side away from the quantitative distribution device gradually rises. As the lowering rod gradually descends, it blocks the subsequent rings, ensuring that only one ring is between the two lowering rods. At this point, as the lowering rod near the quantitative distribution device rises to its highest point, it no longer blocks the ring from moving with the main conveyor belt. This causes the main conveyor belt to carry the ring away from the area between the two lowering rods, allowing each ring to slide into the discharge pipe. A discharge device is then installed to discharge the rings one by one, preventing them from accumulating at the distribution box. When the pusher block slides, it moves the rings that have not entered the distribution box, causing them to fall off the main conveyor belt and into a location outside the main conveyor, resulting in damage or contamination of the rings.

[0027] 3. The movement of the feeding device and the quantitative distribution device is connected by setting up a drive device, a linkage device, and a reciprocating device. When the drive component drives the drive gear to rotate, the output shaft of the drive component drives the drive gear to rotate. The drive gear drives the driven gear to rotate through the chain. Since the driven gear is fixedly connected to the rotating shaft, the driven gear drives the rotating shaft to rotate. The rotation of the rotating shaft drives the rotation of the gear. By setting up the linkage device, the feeding device and the quantitative distribution device are linked to ensure that the feeding device feeds one ring and the quantitative distribution device distributes one ring, thereby avoiding the accumulation of rings at the distribution box, which would cause the rings to fall from the main conveyor belt to places other than the branch conveyor, resulting in the rings being damaged or contaminated.

A linkage device 40 is provided between the discharge device 7 and the quantitative distribution device 4. The linkage device 40 ensures that for every bearing ring placed by the discharge device 7, the quantitative distribution device 4 distributes one bearing ring, preventing bearing rings from accumulating at the distribution box 41 and falling from the main conveyor belt 1 to places outside the branch conveyor belts, thus causing damage or contamination of the bearing rings.

[0033] like Figures 1-2As shown, the quantitative distribution device 4 includes a distribution box 41 for receiving the rings of the main conveyor belt 1, a discharge pipe 42 for conveying to the branch conveyor belt 2, a push block 43 slidably disposed in the distribution box 41, and a drive device 5 for driving the push block 43 to slide.

The ends of the two discharge pipes 42 away from the distribution box 41 are respectively connected to a branch conveyor belt 2. The drive device 5 drives the push block 43 to reciprocate periodically, thereby pushing the rings received in the distribution box 41 to be distributed into the two discharge pipes 42.

[0034] like Figures 2-3 As shown, the drive device 5 includes a mounting shell 51 fixed on the frame 3, a rack 52 slidably connected to the mounting shell 51, a connecting rod 53 connecting the rack 52 and the push block 43, a drive gear 54 driving the rack 52 to slide, and a drive component 55 fixed on the frame 3.

[0035] like Figures 4-5 As shown, the feeding device 7 includes a sliding block 71 slidably connected to the frame 3, a mounting plate 72 fixedly connected to the frame 3, a pressing block 73 fixedly connected to the sliding block 71, and pressing rods 74 connected to the pressing blocks 73. Two pressing rods 74 are provided, both slidably connected to the mounting plate 72. The pressing rods 74 can only slide up and down within the limit of the mounting plate 72. Each pressing rod 74 is connected to a pressing block 73, and both pressing blocks 73 are fixedly connected to the sliding block 71. 62 drives the lower pressure block 73 to reciprocate, which is used to push the two lower pressure rods 74 to descend alternately and move the blocking collar with the conveyor belt. The sliding block 71 is provided with a reciprocating device 30 for driving the sliding block 71 to slide back and forth. A lifting groove 20 for supporting the sliding block 71 is provided between the sliding block 71 and the frame 3. The lifting groove 20 is sleeved on the outside of the sliding block 71 and is fixedly connected to the frame 3. The side of the lifting groove 20 away from the frame 3 has an waist-shaped groove to allow the lower pressure block 73 to slide.

[0036] like Figure 5As shown, the pressing rod 74 abuts against the sliding block 71. A reset device 8 is provided between the pressing rod 74 and the mounting plate 72. The reset device 8 includes a positioning ring 81 fixedly connected to the pressing rod 74 and an elastic element 82 provided between the positioning ring 81 and the mounting plate 72. The elastic element 82 is sleeved on the outside of the pressing rod 74 and is used to push the pressing rod 74 to always abut against the pressing block 73. The two ends of the elastic element 82 are fixedly connected to the positioning ring 81 and the mounting plate 72 respectively. A rolling device 9 is provided between the pressing rod 74 and the pressing block 73. The rolling device 9 includes an abutment block 91 fixedly connected to the pressing rod 74 and a roller 92 rotatably provided in the abutment block 91. The circumferential side wall of the roller 92 has a groove. The roller 92 abuts against the pressing block 73 and the pressing block 73 is located in the groove of the roller 92.

[0037] like Figure 5 As shown, each pressure rod 74 is provided with an anti-deviation device 10 at the end away from the pressure block 73 to prevent the bearing from deviating when it is blocked. The anti-deviation device 10 includes a mounting block 101 fixedly connected to the pressure rod 74 and a blocking pin 102 for blocking the movement of the bearing. There are two blocking pins 102. The two blocking pins 102 are symmetrically arranged along the axis of the main conveyor belt 1 and are fixedly connected to the mounting block 101. The two blocking pins 102 abut against two positions on the outside of the bearing respectively.

[0038] like Figures 4-5As shown, the reciprocating device 30 includes a rotating shaft 301 rotatably connected to the frame 3, a turntable 302 fixedly connected to the rotating shaft 301, a drive rod 303 fixedly connected to the sliding block 71 and a guide block 304 fixedly connected to the frame 3, and a connecting rod 305 connecting the drive rod 303 and the turntable 302. The two ends of the connecting rod 305 are rotatably connected to the drive rod 303 and the turntable 302, respectively. The guide block 304 has a through hole that allows the drive rod 303 to slide to guide the sliding direction of the drive rod 303. A linkage device 40 is provided between the rotating shaft 301 and the drive component 55. In this embodiment, a mounting bracket 50 fixedly connected to the frame 3 is provided at the rotating shaft 301 and the turntable 302. The mounting bracket 50 includes a vertical rod 502 and a horizontal rod 501. Two vertical rods 502 are provided, both of which are fixedly connected to the frame 3. A horizontal bar 501 is horizontally arranged, and its two ends are fixedly connected to two vertical bars 502 respectively. A rotating shaft 301 passes through the horizontal bar 501 and is rotatably connected to it. A turntable 302 and a driven gear 402 are respectively arranged on both sides of the horizontal bar 501 and are both fixedly connected to the rotating shaft 301. In addition, this embodiment provides a turntable 302 structure, which includes an upper plate 3021 and a lower plate 3022. The upper plate 3021 and the lower plate 3022 are symmetrically arranged. The upper plate 3021 is rotatably connected to the frame 3, and the lower plate 3022 is fixedly connected to the rotating shaft 301. One end of a connecting rod 305 is arranged between the upper plate 3021 and the lower plate 3022. Both the upper plate 3021 and the lower plate 3022 are rotatably connected to the connecting rod 305. The upper plate 3021 and the lower plate 3022 are used to ensure the stability of the rotation of the connecting rod 305.

[0039] like Figure 4 As shown, the linkage device 40 includes a driving gear 401 fixedly connected to the output shaft of the driving member 55, a driven gear 402 fixedly connected to the rotating shaft 301, and a chain 403 connecting the driving gear 401 and the driven gear 402. The chain 403 is used to synchronize the rotation of the driving gear 401 and the driven gear 402.

[0040] The basic principle of this embodiment is as follows: When using the dispensing device, the drive unit 55 is first activated to drive the output shaft to rotate. The output shaft drives the drive gear 401 to rotate. The drive gear 401 drives the driven gear 402 to rotate via the chain 403. The driven gear 402 drives the turntable 302 to rotate via the rotating shaft 301. The rotation of the turntable 302 causes the drive rod 303 to drive the sliding block 71 to reciprocate within the lifting groove 20 via the connecting rod 305. The sliding block 71 drives the two lower pressing blocks 73 to reciprocate. When the two lower pressing blocks 73 reciprocate, they drive the two connected lower pressing rods 74 to rise and fall alternately. When the lower pressing block 73 pushes the lower pressing rod 74 to slide downward, the lower pressing rod 74 drives the positioning ring 81 to slide downward to compress the elastic element. When the lower pressing block 73 slides in the opposite direction to release the pressure on the lower pressing rod 74, the elastic element 82 applies an upward elastic force to the positioning ring 81, causing the lower pressing rod 74 to abut against the lower pressing block 73. As the lower pressing block 73 slides, the lower pressing block 73... The moving roller 92 rotates within the abutment block 91; the two downward pressure rods 74 drive the two blocking pins 102 to alternately rise and fall through the mounting block 101 to block and release the rings, ensuring that only one ring enters the distribution box 41 with the conveyor belt at a time. At this time, the output shaft of the drive component 55 drives the drive gear 54 to rotate within the mounting shell 51. The drive gear 54 drives the two symmetrical racks 52 to mesh, thereby driving the racks 52 to slide back and forth within the mounting shell 51. The two racks 52 drive the push block 43 to slide back and forth through the two connecting rods 53, causing the push block 43 to perform periodic back and forth motion within the distribution box 41. The push block 43 evenly distributes the rings entering the distribution box 41 into the two discharge pipes 42, so that the rings are evenly distributed along the discharge pipes 42 to the two branch conveyor belts 2. The mechanical structure is used for even distribution, eliminating the need for manual collection and transportation to different work stations, thus reducing the labor intensity of workers and improving production efficiency.

[0041] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
