Description

Technical Field

[0001] This application relates to the field of bearing processing technology, and in particular to bearing outer ring counters. Background Technology

[0002] Automotive bearings are core components of automotive transmission systems, playing a crucial role in supporting rotating shafts and reducing frictional losses. Their machining precision directly affects the vehicle's operational stability and service life. Bearing manufacturing typically involves multiple precision processes, including forging, heat treatment, turning, grinding, and assembly, each requiring strict control over dimensional accuracy and surface quality. Once the bearings have completed all machining processes and met quality standards, they enter the subsequent counting stage for production tracking, packaging, warehousing, and subsequent logistics management. This counting is primarily achieved through a counter.

[0003] A bearing counter is a device specifically designed to count the number of bearings processed. The processed bearings are fed sequentially into the counter's receiving tray, which serves as a temporary storage and buffer, ensuring the bearings smoothly proceed to the next stage. Subsequently, the bearings are fed out sequentially along a pre-set feeding pipe. Counting sensors are installed at specific locations on the feeding pipe. When a bearing passes a certain position, the sensor accurately identifies the passing signal of the bearing's outer ring and transmits the signal to the counting system, thereby achieving automatic, real-time counting of the bearings.

[0004] Existing bearing counters still have some problems in actual use. When counting bearings, as the receiving tray feeds the bearings into the feeding tube, when there are many bearings, multiple bearings often pass through the counting sensor at the same time. This causes the sensor to be unable to accurately distinguish the signal of a single bearing, resulting in inaccurate counting. Furthermore, when multiple bearings enter the feeding tube side by side, blockage and jamming are also prone to occur, affecting counting efficiency and the normal operation of the equipment. Summary of the Invention

[0005] The purpose of this application is to address the problems mentioned in the background art, such as inaccurate counting caused by multiple bearings passing through the counting sensor simultaneously when there are many bearings, and the problem that blockage and jamming are prone to occur when multiple bearings enter the feed pipe side by side, affecting counting efficiency and normal operation of the equipment. This application provides a bearing outer ring counter.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A bearing outer ring counter includes a housing, a protective door installed on the side of the housing, a receiving tray installed on the top of the housing, a hopper installed on the top of the receiving tray, a feeding pipe fixed on the surface of the receiving tray and connected to the receiving tray, a counting sensor installed at the end of the feeding pipe away from the receiving tray, a control panel provided on the side of the receiving tray and electrically connected to the counting sensor, ventilation holes provided on the side of the housing, and a straightening structure for straightening bearings provided inside the receiving tray.

[0008] The structure includes a first guide bar and a second guide bar fixed inside the receiving tray. The hopper is fixed to the upper end of the second guide bar, and a discharge groove is fixed to the lower end of the second guide bar. A discharge channel is formed between the receiving tray, the first guide bar, and the second guide bar. The discharge channel corresponds to the discharge pipe. A guiding component is provided inside the receiving tray. A rotating component and a collecting component are provided between the receiving tray and the machine casing.

[0009] By adopting the above technical solution, when the bearing outer ring counter is used, the bearing processed by the bearing processing equipment will fall into the receiving tray along the feeding hopper. Then, under the action of the rotating component, the bearing will rotate. Then, under the action of the guiding component and centrifugal force, the bearing will enter the discharge channel through the guiding groove at the lower end of the second guide bar. Under the action of the rotating component, the bearing will enter the feeding pipe in an orderly manner and fall into the pre-placed receiving frame from the feeding pipe. When the bearing passes through the feeding pipe, the counting sensor counts the bearing, thereby achieving accurate counting.

[0010] Furthermore, the material guiding assembly includes a mounting rod fixed inside the receiving tray, and a first guide plate and a second guide plate are rotatably connected to the lower end of the mounting rod. Both the first guide plate and the second guide plate are arc-shaped, and the second guide plate faces the discharge chute.

[0011] By adopting the above technical solution, the first guide plate and the second guide plate can guide the bearing, so that the bearing gradually and orderly enters the inside of the feeding tube, thereby improving the counting accuracy.

[0012] Furthermore, two return springs are fixed at the lower end of the mounting rod, and the ends of the two return springs away from the mounting rod are respectively fixedly connected to the first guide plate and the second guide plate.

[0013] By adopting the above technical solution, the reset spring enables the first guide plate and the second guide plate to have a certain range of motion, which can effectively prevent the bearing from getting stuck in the position of the first guide plate or the second guide plate when rotating, and is more conducive to the regularization of the bearing.

[0014] Furthermore, the rotating assembly includes a drive shaft rotatably connected to the chassis, the output end of the drive shaft extending into the receiving tray and fixed with a rotating disk, the rotating disk being located at the lower end of the first guide plate and the second guide plate.

[0015] By adopting the above technical solution, the drive shaft drives the rotating disk to rotate, which in turn drives the bearing to rotate. In conjunction with the first guide plate and the second guide plate, the bearing enters the feeding tube in an orderly manner.

[0016] Furthermore, a drive motor is fixed inside the chassis, the control panel is electrically connected to the drive motor, a drive gear is fixed at the output end of the drive motor, and a driven gear that meshes with the drive gear is fixed on the drive shaft.

[0017] By adopting the above technical solution, when the drive motor is working, it drives the driving gear to rotate. The rotation of the driving gear causes the driven gear to rotate, which in turn causes the drive shaft to rotate. The rotation of the drive shaft drives the rotating disk to rotate, thereby playing a driving role.

[0018] Furthermore, the collection assembly includes a collection box fixed inside the chassis. A sealing cover is fixed to the front end of the collection box. Two symmetrically arranged guide pipes are fixed to the side of the collection box. The end of the guide pipe away from the collection box passes through the chassis and is fixed with a horn tube. A conveying pipe is fixed to the upper end of the horn tube. Two symmetrically arranged suction pipes are fixed to the upper end of the conveying pipe. Suction holes are opened at the upper end of the suction pipes.

[0019] By adopting the above technical solution, the collection component can collect the dust falling from the bearing surface, thereby reducing the accumulation of dust at the edges of the receiving tray and the rotating tray, which would increase the rotational resistance of the rotating tray.

[0020] Furthermore, the bottom of the receiving tray has four mounting slots that are compatible with the suction pipe. The suction pipe is fixedly installed inside the mounting slots, and the suction pipe corresponds to the edge of the rotating disk.

[0021] By adopting the above technical solution, the suction pipe is installed inside the mounting groove, which can generate negative pressure at the edges of the rotating disc and the receiving disc, making it more conducive to dust collection.

[0022] Furthermore, a transmission shaft is fixed to the lower end of the drive shaft, the transmission shaft extends into the collection box and is rotatably connected to the collection box, an impeller is fixed to one end of the transmission shaft that extends into the collection box, and a through hole is provided on the side of the collection box.

[0023] By adopting the above technical solution, when the drive shaft rotates, the transmission shaft rotates accordingly and drives the impeller to rotate, which generates negative pressure inside the collection box and provides power for collecting dust.

[0024] Furthermore, a collection net is fixed inside the collection box, and a connecting ring is fixed inside the collection net. The drive shaft passes through the connecting ring and is rotatably connected to the connecting ring.

[0025] By adopting the above technical solution, the collection net is used to collect the dust that enters the collection box, so that the dust will not flow out through the through hole on the side of the collection box.

[0026] In summary, this application includes at least one of the following beneficial effects;

[0027] 1. In this application, when counting the processed bearings, the bearings fed into the receiving tray via the hopper fall onto the rotating disk. The drive motor rotates the rotating disk, and the bearings follow, contacting the first guide plate. Under the centrifugal force of the rotating disk and the first guide plate, the bearings gradually approach the edge of the rotating disk. As the rotating disk rotates, the bearings gradually contact the second guide plate. Under the centrifugal force of the second guide plate and the rotating disk, the bearings enter the discharge channel and finally enter the feeding pipe in an orderly manner. The counting of the bearings is achieved through a counting sensor. The orderly structure allows the processed bearings to be organized, ensuring they enter the feeding pipe in an orderly fashion. This effectively reduces the inaccurate counting caused by bearing accumulation during feeding and improves the counting accuracy of the counter.

[0028] 2. At the same time, by organizing the bearings through the structure, the bearings can be orderly entered into the feed tube, which can effectively reduce the problem of material jamming or blockage caused by accumulation at the feed tube, making the feeding of bearings smoother and more conducive to counting bearings.

[0029] 3. In this application, during the process of the drive shaft driving the turntable to align the bearings, the transmission shaft follows the drive shaft and drives the impeller to rotate. The impeller rotation creates a negative pressure inside the collection box. Subsequently, under the action of the guide pipe, trumpet pipe, conveying pipe, and suction pipe, a negative pressure is created at the suction inlet. This allows dust falling from the bearing surface at the edges of the turntable and receiving tray to enter the suction pipe through the suction inlet and finally into the collection box, falling onto the collection net, thus achieving the collection of dust falling from the bearing surface. The collection component can collect the dust falling from the bearing surface, thereby reducing the accumulation of dust at the edges of the receiving tray and turntable, which increases the rotational resistance of the turntable. This, in turn, makes it easier for the turntable to align and deliver the bearings, facilitating subsequent counting.

[0030] 4. At the same time, by collecting the dust falling from the bearing surface, the dust on the receiving tray and rotating tray can be reduced, thereby reducing the problem of bearing surface wear caused by the bearing coming into contact with the accumulated dust during the rotation and straightening process of the rotating tray.

[0031] 5. Furthermore, the rotation of the impeller can accelerate the airflow inside the collection box. After acceleration, the air flows out through the through hole and flows inside the chassis. Finally, it flows out through the ventilation hole on the side of the chassis. When it flows out, it can carry away the heat generated inside the chassis during operation, thus playing a role in heat dissipation. This is more conducive to the normal operation of the entire counter and improves the effectiveness of the counter. Attached Figure Description

[0040] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0041] This application discloses a bearing outer ring counter.

[0042] Reference Figure 1 and Figure 2 The bearing outer ring counter includes a housing 1, a protective door 11 installed on the side of the housing 1, a receiving tray 12 installed on the upper end of the housing 1, a feeding hopper 13 installed on the upper end of the receiving tray 12, the feeding hopper 13 being connected to the discharge port of the bearing processing equipment, the bearing processed by the bearing processing equipment entering the feeding hopper 13, and the bearing being fed into the receiving tray 12 through the feeding hopper 13, a feeding pipe 14 fixed on the surface of the receiving tray 12, the feeding pipe 14 being connected to the receiving tray 12, a counting sensor 15 being installed at the end of the feeding pipe 14 away from the receiving tray 12, a control panel 16 being provided on the side of the receiving tray 12, the control panel 16 being electrically connected to the counting sensor 15, a ventilation hole 17 being provided on the side of the housing 1, and a straightening structure 2 for straightening the bearing being provided inside the receiving tray 12.

[0043] When the bearing outer ring counter is in use, the bearing processed by the bearing processing equipment will fall into the receiving tray 12 along the feeding hopper 13. Then, under the action of the regularization structure 2, the bearing will enter the feeding tube 14 in an orderly manner. When the bearing passes through the counting sensor 15 on the feeding tube 14, the counting sensor 15 will count and display on the control panel 16, thereby achieving accurate counting.

[0044] Reference Figure 2 - Figure 4 The regular structure 2 includes a first guide bar 21 and a second guide bar 22 fixed inside the receiving tray 12. The hopper 13 is fixed to the upper end of the second guide bar 22. The lower end of the second guide bar 22 is fixed with a discharge groove 221. The receiving tray 12 forms a discharge channel 222 with the first guide bar 21 and the second guide bar 22. The discharge channel 222 corresponds to the discharge pipe 14. A guiding component is provided inside the receiving tray 12. A rotating component and a collecting component are provided between the receiving tray 12 and the machine box 1.

[0045] The material guiding assembly includes a mounting rod 23 fixed inside the receiving tray 12. The lower end of the mounting rod 23 is rotatably connected to a first guide plate 231 and a second guide plate 232. Both the first guide plate 231 and the second guide plate 232 are arc-shaped, and the second guide plate 232 faces the discharge chute 221.

[0046] In addition, two return springs 233 are fixed at the lower end of the mounting rod 23. The ends of the two return springs 233 away from the mounting rod 23 are fixedly connected to the first guide plate 231 and the second guide plate 232, respectively. When the bearing rotates with the rotating disk 241, it will come into contact with the first guide plate 231 or the second guide plate 232. After the first guide plate 231 or the second guide plate 232 is resisted by the bearing, it will rotate and pull the return springs 233. When the first guide plate 231 or the second guide plate 232 is no longer resisted by the bearing, the return springs 233 will reset the first guide plate 231 and the second guide plate 232. By setting the first guide plate 231 and the second guide plate 232 with a certain range of motion, it is possible to effectively prevent the bearing from getting stuck in the position of the first guide plate 231 or the second guide plate 232 when rotating, which is more conducive to the regularization of the bearing.

[0047] Furthermore, the rotating assembly includes a drive shaft 24 rotatably connected to the housing 1. The output end of the drive shaft 24 extends into the receiving tray 12 and is fixed with a rotating disk 241. The rotating disk 241 is located at the lower end of the first guide plate 231 and the second guide plate 232. The rotating disk 241 does not contact the first guide plate 231 or the second guide plate 232. The distance between the rotating disk 241 and the first guide plate 231 or the second guide plate 232 is insufficient to allow the bearing to pass through. Therefore, the alignment of the first guide plate 231 and the second guide plate 232 with the bearing can be ensured.

[0048] Furthermore, a drive motor 242 is fixed inside the chassis 1, the control panel 16 is electrically connected to the drive motor 242, a drive gear 243 is fixed at the output end of the drive motor 242, and a driven gear 244 that meshes with the drive gear 243 is fixed on the drive shaft 24.

[0049] When counting the processed bearings, the drive motor 242 is turned on. After the processed bearings enter the receiving tray 12 through the feeding hopper 13, they fall onto the rotating disk 241. When the drive motor 242 is working, it drives the drive gear 243 to rotate. The rotation of the drive gear 243 causes the driven gear 244 to rotate, which in turn causes the drive shaft 24 to rotate. The rotation of the drive shaft 24 drives the rotating disk 241 to rotate. When the rotating disk 241 rotates, under the action of the first guide bar 21 and the second guide bar 22, the bearings that fall onto the rotating disk 241 rotate with the rotating disk 241. When the bearings rotate with the rotating disk 241, they will come into contact with the first guide plate 231. Under the centrifugal force of the first guide plate 231 and the rotating disk 241, the bearing gradually approaches the edge of the rotating disk 241. As the rotating disk 241 rotates, the bearing gradually comes into contact with the second guide plate 232. Under the centrifugal force of the second guide plate 232 and the rotating disk 241, the bearing enters the discharge channel 222 through the guide groove at the lower end of the second guide bar 22. Then, as the rotating disk 241 rotates, the bearing orderly enters the feeding pipe 14 and falls into the pre-placed receiving frame. As the bearing passes through the feeding pipe 14, the counting sensor 15 counts the bearings. The regularization structure 2 can regularize the processed bearings, allowing them to enter the feeding pipe 14 in an orderly manner. This effectively reduces the inaccurate counting caused by bearing accumulation during feeding, improves the counting accuracy of the counter, and the orderly conveying of bearings reduces the accumulation at the feeding pipe 14, which can cause discharge jams or blockages, making it more conducive to bearing counting.

[0050] Reference Figure 3 - Figure 6 The collection assembly includes a collection box 3 fixed inside the housing 1. A sealing cover 31 is fixed to the front end of the collection box 3. Two symmetrically arranged guide pipes 32 are fixed to the side of the collection box 3. The end of the guide pipe 32 away from the collection box 3 passes through the housing 1 and is fixed with a horn pipe 33. A conveying pipe 34 is fixed to the upper end of the horn pipe 33. Two symmetrically arranged suction pipes 35 are fixed to the upper end of the conveying pipe 34. The upper end of the suction pipe 35 is flush with the bottom of the receiving tray 12, so as not to affect the rotation of the rotating disk 241. A suction hole 36 is opened at the upper end of the suction pipe 35.

[0051] The receiving tray 12 has four mounting slots 37 at its bottom that are adapted to the suction pipe 35. The suction pipe 35 is fixedly installed inside the mounting slots 37, and the suction pipe 35 corresponds to the edge of the rotating disk 241.

[0052] In addition, a drive shaft 38 is fixed at the lower end of the drive shaft 24. The drive shaft 38 extends into the collection box 3 and is rotatably connected to the collection box 3. An impeller 381 is fixed at one end of the drive shaft 38 that extends into the collection box 3. A through hole 382 is provided on the side of the collection box 3.

[0053] Furthermore, a collection net 383 is fixed inside the collection box 3, and a connecting ring 384 is fixed inside the collection net 383. The drive shaft 38 passes through the connecting ring 384 and is rotatably connected to the connecting ring 384.

[0054] During the process of the drive shaft 24 driving the turntable to rotate and straighten the bearing, the transmission shaft 38 rotates with the drive shaft 24. The rotation of the transmission shaft 38 causes the impeller 381 at its end to rotate as well. The rotation of the impeller 381 creates a negative pressure inside the collection box 3. Then, under the action of the guide pipe 32, the horn pipe 33, the conveying pipe 34, and the suction pipe 35, a negative pressure is created at the suction port. This negative pressure at the suction port creates a negative pressure at the edges of the turntable 241 and the receiving plate 12. As a result, the dust falling from the bearing surface at the edges of the turntable and the receiving plate 12 can enter the suction pipe 35 through the suction port, then enter the connecting pipe through the suction pipe 35, enter the guide pipe 32 through the horn pipe 33, and finally enter the collection box 3, falling onto the collection net 383, thus achieving the collection of dust falling from the bearing surface. The collecting component can collect the dust falling from the bearing surface, thereby reducing the accumulation of dust at the edges of the receiving tray 12 and the rotating tray 241, which would increase the rotational resistance of the rotating tray 241. This makes it easier for the rotating tray 241 to rotate and deliver the bearing in a regular manner, which is convenient for subsequent counting.

[0055] At the same time, by collecting the dust falling from the bearing surface, the dust on the receiving tray 12 and the rotating tray 241 can be reduced, thereby reducing the problem of bearing surface wear caused by the bearing coming into contact with the accumulated dust during the rotation and straightening process of the rotating tray 241.

[0056] Furthermore, the rotation of impeller 381 can accelerate the airflow inside the collection box 3. After acceleration, the air flows out through the through hole 382 and flows inside the casing 1. Finally, it flows out through the ventilation hole 17 on the side of the casing 1. When it flows out, it can carry away the heat generated inside the casing 1 during operation, thereby playing a role in heat dissipation. This is more conducive to the normal operation of the entire counter and improves the effectiveness of the counter.

[0057] Working principle: When the bearing outer ring counter is in use, the drive motor 242 is turned on. As the bearing processing equipment operates, the processed bearings gradually fall into the receiving tray 12 through the feeding hopper 13. After the processed bearings enter the receiving tray 12 through the feeding hopper 13, they fall onto the rotating disk 241. When the drive motor 242 is working, it drives the drive gear 243 to rotate. The rotation of the drive gear 243 causes the driven gear 244 to rotate, thereby causing the drive shaft 24 to rotate. The rotation of the drive shaft 24 drives the rotating disk 241 to rotate. When the rotating disk 241 rotates, under the action of the first guide bar 21 and the second guide bar 22, the bearings that fall onto the rotating disk 241 rotate with the rotating disk 241. When 241 rotates, it will come into contact with the first guide plate 231. Under the centrifugal force of the first guide plate 231 and the rotating disk 241 rotating together, the bearing will gradually approach the edge of the rotating disk 241. As the rotating disk 241 rotates, the bearing will gradually come into contact with the second guide plate 232. Under the centrifugal force of the second guide plate 232 and the rotating disk 241, the bearing will enter the discharge channel 222 through the guide groove at the lower end of the second guide bar 22. In the discharge channel 222, the bearing will then enter the discharge pipe 14 in an orderly manner as the rotating disk 241 rotates. It will fall from the discharge pipe 14 into the pre-placed receiving frame. When the bearing passes through the discharge pipe 14, the counting sensor 15 counts the bearing.

[0058] During the process of the drive shaft 24 driving the turntable to rotate and straighten the bearing, the transmission shaft 38 rotates with the drive shaft 24. The rotation of the transmission shaft 38 causes the impeller 381 at its end to rotate as well. The rotation of the impeller 381 creates a negative pressure inside the collection box 3. Then, under the action of the guide pipe 32, the horn pipe 33, the conveying pipe 34, and the suction pipe 35, a negative pressure is created at the suction port. This negative pressure at the suction port creates a negative pressure at the edges of the turntable 241 and the receiving plate 12. As a result, the dust falling from the bearing surface at the edges of the turntable and the receiving plate 12 can enter the suction pipe 35 through the suction port, then enter the connecting pipe through the suction pipe 35, enter the guide pipe 32 through the horn pipe 33, and finally enter the collection box 3, falling onto the collection net 383, thus achieving the collection of dust falling from the bearing surface.
