Description

Technical Field

[0001] This invention relates to the field of automatic bearing inspection technology, specifically to a bearing ring size inspection device and its usage method. Background Technology

[0002] Bearing rings are ring-shaped parts of radial rolling bearings with one or more raceways. They are important components of rolling bearings. Due to the wide variety of rolling bearings, the size, structure, manufacturing equipment, and processes of the rings vary from type to type. Furthermore, the ring processing involves many steps, complex processes, and high precision requirements. Therefore, the processing quality of the rings has a significant impact on the accuracy, service life, and performance of the bearing.

[0003] In existing technologies, when it is necessary to inspect bearing races, workers usually need to use testing equipment to measure the inner and outer diameters of each bearing race to determine whether the manufactured bearing races are qualified. This often requires workers to spend a lot of time manually measuring each bearing race in a batch, which is not only labor-intensive but also inefficient. In addition, after obtaining the measurement data, workers still need to separate qualified and defective products for storage, which is not convenient. Therefore, there is a need for a device that can automatically inspect bearing races during transportation and can separate qualified and defective products for storage to avoid low inspection efficiency and inconvenience.

The bottom of the mounting bracket is fixedly connected to the top of the mounting plate. The hook rod is locked on the locking gear. A protrusion that contacts the cam is fixedly connected to one side of the hook rod.

[0006] Preferably, the receiving assembly includes a housing, with a mounting box connected to the side of the housing away from the workpiece transport table. A stepper motor is housed within the mounting box, and a drive gear is mounted on the output end of the stepper motor. Two sliding grooves are formed on the side of the mounting box near the housing, and a sliding box is slidably mounted on these grooves. Two conductive elements are symmetrically arranged on the side of the housing near the workpiece transport table. Insulating sleeves are threaded through the two through slots on the housing. One end of each insulating sleeve is fixedly connected to a conductive element, and the other end is fixedly connected to the side of the sliding box. An L-shaped toothed rod is fixedly connected to the bottom of the box. The teeth of the two L-shaped toothed rods mesh with the upper and lower parts of the drive gear, respectively. An external power supply is provided in one of the sliding boxes. The power supply terminals of the stepper motor are electrically connected to a first wire. One of the first wires passes through the sliding box and the insulating sleeve and is electrically connected to one side of the conductive component. The other first wire passes through the side of the other sliding box and is electrically connected to the positive terminal of the external power supply. The negative terminal of the external power supply is electrically connected to a second wire. The other end of the second wire passes through the insulating sleeve and is electrically connected to the side of the other conductive component.

[0007] Preferably, the detection assembly includes a slide rail disposed on the front of the housing and above the conductive component. A top rod is provided inside the slide rail, and a damping sheet is laid on the inner wall of the slide rail. The bottom of the top rod is movably connected to the bottom of the inner wall of the slide rail via a pressure spring. A sliding plate is provided on the side end of the top rod, and the end of the sliding plate away from the top rod is slidably connected to a detection groove opened on the front of the housing. A detection sleeve is fixedly connected inside the housing, and a detection component is slidably connected inside the detection sleeve. One end of the detection component extends into the detection groove and is located above the top rod. The bottom of the detection component is movably connected to one end of a Z-shaped connecting rod via a linkage rod. The other end of the Z-shaped connecting rod is hinged to one end of a hinge frame, and one side of the hinge frame is fixedly installed on the inner wall of the housing.

[0008] Preferably, the trigger collection assembly includes a V-shaped cover plate. The middle part of the V-shaped cover plate is rotatably connected to the storage box via a rotating shaft. One end of the rotating shaft passes through the storage box and extends to its outside, where a crank is sleeved. One end of the crank is rotatably connected to a drive rod. One end of the drive rod passes through a moving slot opened on the front of the box and extends into the box, where it is slidably connected to a guide rail. The side of the guide rail is rotatably connected to the inner wall of the box. An auxiliary rail is fixedly connected to the front of the box and located below the drive rod. A triangular limiting frame is slidably mounted on the auxiliary rail, and the drive rod is hinged to the triangular limiting frame. One side of the triangular limiting frame is movably connected to one side of the inner wall of the auxiliary rail via a return spring.

[0009] Preferably, the ejector assembly includes a support rod, and the top of each insulating sleeve is fixedly connected to the support rod. The top of the support rod is fixedly connected to a pull rod, and the top of the side surface of the pull rod is fixedly connected to a toggle rod. A toggle plate is sleeved on the toggle rod, and the toggle rod passes through a through groove opened on the toggle plate. The opposite sides of the two toggle plates are connected by a linkage turntable. The side surface of the linkage turntable engages with the ejector toothed rod through teeth provided thereon. The ejector toothed rod slides through the housing. One end of the ejector toothed rod is fixedly connected to an ejector head. The ejector head is located inside the housing and corresponds to the position of the circular hole. A spring is sleeved on the ejector head, and the spring is engaged in an annular groove opened on the inner wall of the circular hole.

[0010] Preferably, the storage box has retrieval doors on both sides that can be opened and closed.

[0011] Preferably, the method of using the bearing ring size detection device includes the following steps:

[0012] S1: When several bearing rings move on the workpiece transport table, the drive motor is controlled to rotate the cam. When the protrusion on the cam presses against the protrusion, the hook rod rotates through the pin and stretches the tension spring. When the bearing ring hits the actuating part, the locking gear rotates and is smoothly unloaded. When the protrusion on the cam does not fit against the protrusion, the hook rod re-locks onto the locking gear through the pin and tension spring, thus restricting the unloading of the bearing ring. When the protrusion on the cam presses against the protrusion again, the bearing ring is smoothly unloaded. This allows the bearing rings to move sequentially and at intervals to the unloading end of the workpiece transport table, facilitating the inspection of each bearing ring and improving the convenience of the operation.

[0013] S2: When each bearing ring falls from the unloading end of the workpiece transport table and hangs on two conductive parts, the external power supply drives the stepper motor through the first and second wires, which in turn drives the drive gear to rotate. This causes the two L-shaped toothed rods to move relatively away, which in turn causes the two sliding boxes to move relative to each other. This causes the conductive parts to contact one side of the bearing ring and press against it. Since the bearing ring is hollow and circular, when the two conductive parts press against each other, the bearing ring will gradually move upward from its original state of being suspended on the two conductive parts, so that the two conductive parts are located in the center of the bearing ring. This allows the inner diameter of the bearing ring to be detected, thereby determining whether the inner diameter is qualified. This completes the automatic detection of each bearing ring. The insulating sleeve effectively prevents leakage accidents, thereby improving the safety during operation.

[0014] S3: During the upward movement of the bearing ring, the top of the bearing ring contacts the bottom of the push rod, causing the push rod to move upward within the slide rail via a pressure spring. This moves the slide plate, which in turn moves the other end of the slide plate within the detection slot, thus detecting the outer diameter of the bearing ring. When the bearing ring meets the standard, one end of the slide plate abuts against the detection piece and remains pressed against it. This moves the detection piece within the detection sleeve, causing the Z-shaped connecting rod to rotate on the hinged frame via the linkage rod. This strikes the top of the guide rail and causes the guide rail to rotate within the housing. This, in turn, drives the triangular limit frame to move towards the housing via the drive rod on the auxiliary track, causing the crank to rotate. This, in turn, causes the V-shaped cover to rotate on top of the storage box, opening the area for receiving products that meet specifications. The top of the V-shaped cover forms... The inclined surface facilitates the smooth rolling of the bearing rings into the storage box during unloading. When the bearing rings do not meet the standard, the area on the storage box that receives compliant products remains closed while the area that receives non-compliant products remains open, as one end of the slide plate cannot contact the inspection piece. When one end of the slide plate slides above the inspection piece, a reset spring quickly helps the guide rail to reset as it rotates, thus restoring the V-shaped cover to its initial position. Furthermore, a damping plate inside the slide rail slowly resets the push rod via a pressure spring during unloading, causing the slide plate to slowly move up and down from the inspection piece. This allows the bearing rings sufficient time to roll into the storage box to collect compliant products, enabling automatic inspection of each bearing ring during transportation, thereby improving inspection efficiency and enhancing the practicality of the device.

[0015] S4: When the two conductive parts move away from each other, they cause the two insulating sleeves to move away from each other. Since the stepper motor can rotate freely through the electromagnet, the two conductive parts move closer to each other after moving a certain distance away. This causes the two insulating sleeves to move closer to each other, so that the bearing rings are resuspended on the two conductive parts. The pull rod drives the actuating rod to slide in the actuating plate, thereby driving the linkage turntable to rotate. Then, the local teeth drive the ejector tooth groove rod to move, so that the ejector head can collect the bearing rings located on the two conductive parts. After the teeth have made contact, the spring will drive the ejector head to reset, which will facilitate the next bearing ring inspection process and improve convenience.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] In this invention, when the device is in use, as several bearing rings move towards their unloading end via the workpiece transport table, the intermittent unloading component is controlled to operate, allowing the bearing rings to move sequentially and at intervals to the unloading end and then to the side of the receiving component. When a bearing ring falls from the unloading end of the workpiece transport table, the receiving component catches it at its side. Subsequently, a detection component automatically operates when each bearing ring catches, detecting the inner diameter of the bearing ring. During the detection process, the bearing ring moves towards the detection component, and the detection component detects the outer diameter of the bearing ring. When the bearing ring meets the standard, the collection component is triggered to open the area for receiving products that meet the specifications. After testing, the bearing race is detached from the testing device and collected when it passes through the ejector assembly. If the bearing race does not meet the standard, the collection assembly is disabled, thus closing the area for receiving compliant products and simultaneously opening the area for non-compliant products, which are then collected through the ejector assembly. This process avoids the need for personnel to use testing equipment to measure the inner and outer diameters of each bearing race, reducing a large number of work steps and improving testing efficiency. Furthermore, after obtaining the results, personnel can automatically separate and store qualified and non-qualified products, further enhancing convenience. This achieves automatic testing of bearing races during transportation and separates qualified and defective products for storage, avoiding inefficiency and inconvenience.

[0018] In this invention, when several bearing rings move on the workpiece transport table, the drive motor is controlled to rotate the cam. When the protrusion on the cam presses against the protrusion, the hook rod rotates through the pin and stretches the tension spring. When the bearing rings hit the actuating part, the locking gear rotates and is smoothly unloaded. When the protrusion on the cam does not fit against the protrusion, the hook rod re-locks onto the locking gear through the pin and tension spring, thus restricting the unloading of the bearing rings. When the protrusion on the cam presses against the protrusion again, the bearing rings are smoothly unloaded. This allows the bearing rings to move sequentially and at intervals to the unloading end of the workpiece transport table, facilitating the inspection of each bearing ring and improving the convenience of operation.

[0019] In this invention, when each bearing ring falls from the unloading end of the workpiece transport table and hangs on two conductive components, an external power supply drives a stepper motor via a first and second wire. This drives a drive gear to rotate, causing two L-shaped toothed rods to move relatively away. This, in turn, causes two sliding boxes to move relative to each other, resulting in the conductive components contacting and pressing against one side of the bearing ring's interior. Since the bearing ring is hollow and circular, as the two conductive components press against each other, the bearing ring gradually moves upward from its original suspended state, bringing the two conductive components to the center of the bearing ring. This allows for the detection of the bearing ring's inner diameter, determining whether it meets the requirements. This completes the automatic detection of each bearing ring. The insulating sleeve effectively prevents leakage accidents, thus improving operational safety.

[0020] In this invention, during the upward movement of the bearing ring, the top of the bearing ring contacts the bottom of the push rod, causing the push rod to move upward within the slide rail via a pressure spring. This, in turn, moves the sliding plate, causing the other end of the sliding plate to move within the detection groove, thereby detecting the outer diameter of the bearing ring. When the bearing ring meets the standard, one end of the sliding plate abuts against the detection piece and remains pressed against it, causing the detection piece to move within the detection sleeve. This, in turn, drives the Z-shaped connecting rod to rotate on the hinge frame via the linkage rod, striking the top of the guide rail and causing the guide rail to rotate within the housing. This, in turn, drives the triangular limit frame to move towards the housing via the drive rod on the auxiliary track, causing the crank to rotate. This, in turn, causes the V-shaped cover to rotate on the top of the storage box, opening the area for receiving products that meet the specifications. The top of the V-shaped cover forms a... The inclined surface facilitates the smooth rolling of the bearing rings into the storage box during unloading. When the bearing rings do not meet the standard, the area on the storage box that receives compliant products remains closed while the area that receives non-compliant products remains open, as one end of the slide plate cannot contact the inspection piece. When one end of the slide plate slides above the inspection piece, a reset spring quickly helps the guide rail to reset as it rotates, thus restoring the V-shaped cover to its initial position. Furthermore, a damping plate inside the slide rail slowly resets the push rod via a pressure spring during unloading, causing the slide plate to slowly move up and down from the inspection piece. This allows the bearing rings sufficient time to roll into the storage box to collect compliant products, enabling automatic inspection of each bearing ring during transportation, thereby improving inspection efficiency and enhancing the practicality of the device.

[0021] In this invention, when the two conductive components move away from each other, the two insulating sleeves move away from each other. Since the stepper motor can rotate freely through the electromagnet, the two conductive components move a certain distance away from each other and then move closer together, causing the two insulating sleeves to move closer together. This allows the bearing rings to be resuspended on the two conductive components. The pull rod then drives the actuating rod to slide within the actuating plate, thereby driving the linkage turntable to rotate. Subsequently, the teeth drive the ejector toothed rod to move, thereby collecting the bearing rings located on the two conductive components through the ejector head. After the teeth have made contact, the spring plate drives the ejector head to reset, facilitating the next bearing ring inspection process and improving convenience.

[0022] In this invention, once a certain number of bearing rings are stored in the storage box, workers can move the stored bearing rings through the designated retrieval door, which also facilitates the subsequent testing process. Attached Figure Description

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1 to 12 This invention provides a technical solution: a bearing ring size detection device, including a base plate 1, a workpiece transport table 2 is provided on one side of the top of the base plate 1, an intermittent feeding component 3 is provided in the mounting groove opened on the workpiece transport table 2, a receiving component 5 is provided on the other side of the top of the base plate 1, a detection device 7 for detecting the workpiece is provided on the receiving component 5, a storage box 8 is provided between the receiving component 5 and the workpiece transport table 2, the top of the storage box 8 is open, the detection device 7 is provided with an ejection component 9, the detection device 7 includes a detection component 71 and a trigger collection component 73, the detection component 71 is located at the side end of the receiving component 5, and the trigger collection component 73 is located above the detection component 71.

[0038] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the intermittent feeding assembly 3 includes a mounting plate 31. The side end of the mounting plate 31 is fixedly connected to the inner wall of the mounting groove on the workpiece transport table 2. A locking gear 32 is rotatably connected to the mounting plate 31. The locking gear 32 is provided with a toggle member 33, and the side end of the toggle member 33 is located on the workpiece transport table 2 through a through groove. A mounting bracket 34 is provided on the side end of the locking gear 32. A cam 35 is provided on the mounting bracket 34 and rotatably connected to it. A drive motor 36 is provided at the bottom of the mounting plate 31, and the output end of the drive motor 36 passes through the mounting plate 31 and is connected to the cam 35. A hook rod 38 is rotatably connected to the top of the mounting plate 31 through a pin 37. One side of the hook rod 38 is movably connected to one side of the mounting bracket 34 through a tension spring 39. The bottom of the mounting bracket 34 is fixedly connected to the top of the mounting plate 31. The hook rod 38 is locked on the locking gear 32. A protrusion 40 that contacts the cam 35 is fixedly connected to one side of the hook rod 38.

[0039] When several bearing rings move on the workpiece transport table 2, the drive motor 36 is controlled to operate, thereby driving the cam 35 to rotate. When the protrusion on the cam 35 presses against the protrusion 40, the hook rod 38 rotates through the pin 37 and stretches the tension spring 39. Thus, when the bearing ring hits the actuating element 33, it can drive the locking gear 32 to rotate and smoothly unload the bearing ring. When the protrusion on the cam 35 does not fit against the protrusion 40, the hook rod 38 re-locks onto the locking gear 32 through the pin 37 and the tension spring 39, thereby restricting the unloading of the bearing ring. When the protrusion 40 on the cam 35 presses against the protrusion 40 again, the bearing ring is smoothly unloaded. This allows the bearing rings to move sequentially and at intervals to the unloading end of the workpiece transport table 2, facilitating the inspection of each bearing ring and improving the convenience of operation.

[0040] In this embodiment, as Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the receiving assembly 5 includes a housing 51. A mounting box 52 is connected to the side of the housing 51 away from the workpiece transport table 2. A stepper motor 53 is housed inside the mounting box 52, and a drive gear 54 is provided on the output end of the stepper motor 53. Two sliding grooves are formed on the side of the mounting box 52 near the housing 51, and a sliding box 55 is slidably mounted on the sliding grooves. Two conductive elements 56 are symmetrically arranged on the side of the housing 51 near the workpiece transport table 2. Insulating sleeves 57 are connected through the two through slots formed on the housing 51. One end of the insulating sleeve 57 is fixedly connected to a conductive element 56, and the other end of the insulating sleeve 57 is fixedly connected to the side of the sliding box 55. An L-shaped toothed rod 58 is fixedly connected to the bottom of the box 55. The teeth of the two L-shaped toothed rods mesh with the upper and lower parts of the drive gear 54 respectively. An external power supply 59 is provided in one of the sliding boxes 55. The power supply terminals of the stepper motor 53 are electrically connected to the first wires 60. One of the first wires 60 passes through the sliding box 55 and the insulating sleeve 57 and is electrically connected to one side of the conductive member 56. The other first wire 60 passes through the side of the other sliding box 55 and is electrically connected to the positive terminal of the external power supply 59. The negative terminal of the external power supply 59 is electrically connected to the second wire 61. The other end of the second wire 61 passes through the insulating sleeve 57 and is electrically connected to the side of the other conductive member 56.

[0041] When each bearing ring falls from the unloading end of the workpiece transport table 2 and hangs on two conductive parts 56, the external power supply 59 drives the stepper motor 53 through the first wire 60 and the second wire 61, thereby driving the drive gear 54 to rotate. This causes the two L-shaped toothed rods 58 to move relatively away, which in turn causes the two sliding boxes 55 to move relative to each other. As a result, the conductive parts 56 contact one side of the inside of the bearing ring and press against it. Since the inside of the bearing ring is hollow and circular, when the two conductive parts 56 press against each other, the bearing ring will gradually move upward from its original state of being suspended on the two conductive parts 56, so that the two conductive parts 56 are located at the center of the bearing ring. This allows for the detection of the inner diameter of the bearing ring, thereby determining whether the inner diameter is qualified. This completes the automatic detection of each bearing ring. The insulating sleeve 57 effectively prevents leakage accidents, thereby improving safety during operation.

[0042] In this embodiment, as Figure 9 , Figure 10 , Figure 11 and Figure 12As shown, the detection component 71 includes a slide rail 711, which is disposed on the front of the housing 51 and above the conductive component 56. A top rod 712 is provided inside the slide rail 711, and damping sheets are laid on the inner wall of the slide rail 711. The bottom of the top rod 712 is movably connected to the bottom of the inner wall of the slide rail 711 via a pressure spring 713. A sliding plate 714 is provided on the side end of the top rod 712, and the end of the sliding plate 714 away from the top rod 712 is slidably connected to a detection opening on the front of the housing 51. Inside the test slot 715, a test sleeve 716 is fixedly connected inside the housing 51. A test element 717 is slidably connected inside the test sleeve 716. One end of the test element 717 extends into the test slot 715 and is located above the top rod 712. The bottom of the test element 717 is movably connected to one end of a Z-shaped connecting rod 719 via a linkage rod 718. The other end of the Z-shaped connecting rod 719 is hinged to one end of a hinge frame 720. One side of the hinge frame 720 is fixedly installed on the inner wall of the housing 51.

[0043] The trigger collection component 73 includes a V-shaped cover plate 731. The middle part of the V-shaped cover plate 731 is rotatably connected to the storage box 8 via a rotating shaft 732. One end of the rotating shaft 732 passes through the storage box 8 and extends to the outside of it, where a crank is sleeved. One end of the crank is rotatably connected to a drive rod 733. One end of the drive rod 733 passes through a moving slot opened on the front of the housing 51 and extends into the housing 51 and is slidably connected to a guide rail 734. The side of the guide rail 734 is rotatably connected to the inner wall of the housing 51. An auxiliary rail 735 is fixedly connected to the front of the housing 51 and is located below the drive rod 733. A triangular limit frame 736 is slidably provided on the auxiliary rail 735, and the drive rod 733 is hinged to the triangular limit frame 736. One side of the triangular limit frame 736 is movably connected to one side of the inner wall of the auxiliary rail 735 via a return spring 737. The top of the guide rail 734 is attached to the corner of the Z-shaped connecting rod 719.

[0044] During the upward movement of the bearing ring, the top of the bearing ring contacts the bottom of the push rod 712, causing the push rod 712 to move upward within the slide rail 711 via the pressure spring 713. This, in turn, moves the slide plate 714, causing its other end to move within the detection groove 715. This allows for the detection of the outer diameter of the bearing ring. When the bearing ring meets the standard, one end of the slide plate 714 abuts against and remains pressed against the detection element 717, thereby driving the detection... The test piece 717 moves within the test sleeve 716, thereby driving the Z-shaped connecting rod 719 to rotate on the hinge frame 720 via the linkage rod 718. This strikes the top of the guide rail 734, causing the guide rail 734 to rotate within the housing 51. This, in turn, drives the triangular limit frame 736 to move towards the housing 51 on the auxiliary track 735 via the drive rod 733. This causes the crank to rotate, which in turn rotates the V-shaped cover 731 on top of the storage box 8, opening the area for receiving compliant products. The inclined surface formed at the top of the V-shaped cover plate 731 facilitates the smooth rolling of the bearing rings into the storage box 8 during unloading. When the bearing rings do not meet the standards, the area on the storage box 8 that receives compliant products remains closed, while the area that receives non-compliant products remains open, as one end of the slide plate 714 cannot contact the detection piece 717. When one end of the slide plate 714 slides upward past the detection piece 717, the reset spring 737 quickly helps the guide rail 734 to reset as it rotates, thus restoring the V-shaped cover plate 731 to its initial position. Furthermore, the damping plate inside the slide rail 711 allows the push rod 712 to slowly reset via the pressure spring 713 during unloading, causing the slide plate 714 to slowly move up and down from the detection piece 717. This gives the bearing rings sufficient time to roll into the storage box 8 to collect compliant products, enabling automatic inspection of each bearing ring during transportation, thereby improving inspection efficiency and enhancing the practicality of the device.

[0045] In this embodiment, as Figure 8As shown, the ejector assembly 9 includes a support rod 91. The top of each insulating sleeve 57 is fixedly connected to the support rod 91. The top of the support rod 91 is fixedly connected to a pull rod 92. The top of the side surface of the pull rod 92 is fixedly connected to a toggle rod 93. A toggle plate 94 is sleeved on the toggle rod 93, and the toggle rod 93 passes through a through groove opened on the toggle plate 94. The two toggle plates 94 are connected on opposite sides by a linkage turntable. The side surface of the linkage turntable meshes with the ejector toothed rod 96 through teeth 95. The ejector toothed rod 96 slides through the housing 51. One end of the ejector toothed rod is fixedly connected to an ejector head 97. The ejector head 97 is located inside the housing 51 and corresponds to the position of the circular hole. A spring piece 98 is sleeved on the ejector head 97, and the spring piece 98 is engaged in an annular groove opened on the inner wall of the circular hole.

[0046] When the two conductive parts 56 move away from each other, the two insulating sleeves 57 move away from each other. Since the stepper motor 53 can rotate freely through the electromagnet, the two conductive parts 56 move a certain distance away from each other and then move closer to each other, thereby bringing the two insulating sleeves 57 closer to each other. This causes the bearing rings to be resuspended on the two conductive parts 56. The pull rod 92 drives the actuating rod 93 to slide within the actuating plate 94, thereby driving the linkage turntable to rotate. Then, the local teeth 95 drive the ejector toothed rod 96 to move, thereby collecting the bearing rings located on the two conductive parts 56 through the ejector head 97. After the teeth 95 have made contact, the spring 98 drives the ejector head 97 to reset, which facilitates the next bearing ring inspection process and improves convenience.

[0047] In this embodiment, as Figure 1 As shown, the storage box 8 is provided with retrieval doors 10 on both sides that can be opened and closed; when the storage box 8 contains a certain number of bearing rings, the staff can move the stored bearing rings through the retrieval doors 10, which also facilitates the subsequent testing process.

[0048] The method of use and advantages of the present invention: The working process of the bearing ring size detection device is as follows:

[0049] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown:

[0050] S1: When several bearing rings move on the workpiece transport table 2, the drive motor 36 is controlled to work, thereby driving the cam 35 to rotate. When the protrusion on the cam 35 presses against the protrusion 40, the hook rod 38 is driven to rotate through the pin 37 and stretch the tension spring 39. Thus, when the bearing ring hits the actuating part 33, the locking gear 32 can be driven to rotate and be smoothly unloaded. When the protrusion on the cam 35 does not fit with the protrusion 40, the hook rod 38 is re-locked on the locking gear 32 through the pin 37 and the tension spring 39, thereby restricting the unloading of the bearing ring. When the protrusion 40 on the cam 35 presses against the protrusion 40 again, the bearing ring is smoothly unloaded. Thus, the bearing rings can move sequentially and at intervals to the unloading end of the workpiece transport table 2, which facilitates the inspection of each bearing ring and improves the convenience of work.

[0051] S2: When each bearing ring falls from the unloading end of the workpiece transport table 2 and hangs on two conductive parts 56, the external power supply 59 drives the stepper motor 53 through the first wire 60 and the second wire 61, thereby driving the drive gear 54 to rotate, which in turn drives the two L-shaped toothed rods 58 to move relatively away, thereby driving the two sliding boxes 55 to move relative to each other, and thus causing the conductive parts 56 to contact one side of the inside of the bearing ring and press against it. Since the inside of the bearing ring is hollow and circular, when the two conductive parts 56 press against each other, the bearing ring will gradually move upward from the original state of being suspended on the two conductive parts 56, so that the two conductive parts 56 are located in the center of the bearing ring, thereby detecting the inner diameter of the bearing ring and determining whether the inner diameter is qualified, thus completing the automatic detection of each bearing ring. The insulating sleeve 57 can effectively prevent the occurrence of leakage accidents, thereby improving the safety during operation.

[0052] S3: During the upward movement of the bearing ring, the top of the bearing ring contacts the bottom of the push rod 712, causing the push rod 712 to move upward within the slide rail 711 via the pressure spring 713. This, in turn, moves the slide plate 714, causing its other end to move within the detection groove 715. This allows for the detection of the outer diameter of the bearing ring. When the bearing ring meets the standard, one end of the slide plate 714 abuts against the detection element 717 and remains pressed against it. The moving detection element 717 moves within the detection sleeve 716, thereby driving the Z-shaped connecting rod 719 to rotate on the hinge frame 720 via the linkage rod 718. This strikes the top of the guide rail 734, causing the guide rail 734 to rotate within the housing 51. This, in turn, drives the triangular limit frame 736 to move towards the housing 51 on the auxiliary track 735 via the drive rod 733. This causes the crank to rotate, which in turn rotates the V-shaped cover 731 on top of the storage box 8, opening the area for receiving compliant products. The inclined surface formed by the top of the V-shaped cover plate 731 facilitates the smooth rolling of the bearing rings into the storage box 8 during unloading. When the bearing rings do not meet the standard, the area on the storage box 8 that receives compliant products remains closed, while the area that receives non-compliant products remains open, as one end of the slide plate 714 cannot contact the detection piece 717. When one end of the slide plate 714 slides above the detection piece 717, the reset spring 737 quickly helps the guide rail 734 to reset as it rotates, thus restoring the V-shaped cover plate 731 to its initial position. Furthermore, the damping plate inside the slide rail 711 allows the push rod 712 to slowly reset via the pressure spring 713 during unloading, causing the slide plate 714 to slowly move up and down from the detection piece 717. This gives the bearing rings sufficient time to roll into the storage box 8 to collect compliant products, thereby enabling automatic inspection of each bearing ring during transportation, improving inspection efficiency and further enhancing the practicality of the device.

[0053] S4: When the two conductive parts 56 move away from each other, the two insulating sleeves 57 move away from each other. Since the stepper motor 53 can rotate freely through the electromagnet, the two conductive parts 56 move a certain distance away from each other and then move closer to each other, thereby causing the two insulating sleeves 57 to move closer to each other. This causes the bearing rings to be resuspended on the two conductive parts 56. The pull rod 92 drives the actuating rod 93 to slide in the actuating plate 94, thereby driving the linkage turntable to rotate. Then, the local teeth 95 drive the ejector toothed rod 96 to move, thereby collecting the bearing rings located on the two conductive parts 56 through the ejector head 97. After the teeth 95 have made contact, the spring 98 drives the ejector head 97 to reset, which facilitates the next bearing ring inspection process and improves convenience.

6. A method of using a bearing ring size inspection device, comprising using the bearing ring size inspection device as described in any one of claims 1-5, characterized in that, Includes the following steps: S1: When several bearing rings move on the workpiece transport table (2), the drive motor (36) is controlled to work, thereby driving the cam (35) to rotate. When the protrusion on the cam (35) presses against the protrusion (40), the hook rod (38) is driven to rotate through the pin (37) and stretch the tension spring (39). Thus, when the bearing rings hit the actuating part (33), the locking gear (32) can be driven to rotate and smoothly unload the material. When the protrusion on the cam (35)... When the starting part does not fit with the protrusion (40), the hook rod (38) passes through the pin (37) and the tension spring (39) and is re-locked on the locking gear (32), thereby restricting the bearing ring from being unloaded. When the protrusion (40) on the cam (35) presses against the protrusion (40) again, the bearing ring is unloaded smoothly, so that the bearing ring can be moved sequentially and at intervals to the unloading end of the workpiece transport table (2), which facilitates the inspection of each bearing ring and improves the convenience of work. S2: When each bearing ring falls from the unloading end of the workpiece transport table (2) and hangs on two conductive parts (56), the external power supply (59) drives the stepper motor (53) through the first wire (60) and the second wire (61) to work, thereby driving the drive gear (54) to rotate, thereby driving the two L-shaped toothed rods (58) to move relatively away, thereby driving the two sliding boxes (55) to move relative to each other, thereby driving the conductive parts (56) to contact one side of the bearing ring and press against it. Since the bearing ring is hollow and circular inside, when the two conductive parts (56) press against each other, the bearing ring will gradually move upward from the original state of hanging on the two conductive parts (56), so that the two conductive parts (56) are located in the center of the bearing ring, thereby detecting the inner diameter of the bearing ring, thereby determining whether the inner diameter is qualified, and the insulating sleeve (57) can effectively prevent the occurrence of leakage accidents, thereby improving the safety during operation. S3: During the upward movement of the bearing ring, the top of the bearing ring contacts the bottom of the push rod (712), thereby causing the push rod (712) to move upward within the slide rail (711) via the pressure spring (713), which in turn causes the slide plate (714) to move, thereby causing the other end of the slide plate (714) to move within the detection groove (715), thus detecting the outer diameter of the bearing ring. When the bearing ring meets the standard, one end of the slide plate (714) abuts against the detection piece (717) and remains pressed against the detection piece (717), thereby causing... The moving detection element (717) moves within the detection sleeve (716), thereby driving the Z-shaped connecting rod (719) to rotate on the hinge frame (720) via the linkage rod (718). This strikes the top of the guide rail (734) and causes the guide rail (734) to rotate within the housing (51). This, in turn, drives the triangular limit frame (736) to move towards the housing (51) on the auxiliary track (735) via the drive rod (733). This causes the crank to rotate, which in turn causes the V-shaped cover plate (731) to rotate on the top of the storage box (8), thereby opening the receiving device. The area for receiving standard products is connected by a slope formed at the top of a V-shaped cover plate (731), which facilitates the smooth rolling of bearing rings into the storage box (8) during unloading. When the bearing rings do not meet the standard, the area on the storage box (8) for receiving standard products is always closed, and the area for receiving non-standard products is always open. When one end of the slide plate (714) slides to the top through the detection piece (717), the reset spring (737) quickly assists the guide rail (734) in rotating as the guide rail (734) rotates. The V-shaped cover plate (731) is reset to its initial position. The damping plate inside the slide rail (711) allows the bearing ring to be reset slowly by the pressure spring (713) during unloading. This causes the slide plate (714) to move slowly up and down from the detection piece (717), giving the bearing ring a certain amount of time to roll into the storage box (8) to collect products that meet the specifications. This allows for automatic detection of each bearing ring during transportation, thereby improving detection efficiency and further enhancing the practicality of the device. S4: When the two conductive parts (56) move away from each other, the two insulating sleeves (57) move away from each other. Since the stepper motor (53) can rotate freely through the electromagnet, the two conductive parts (56) move a certain distance away from each other and then move closer to each other, thereby causing the two insulating sleeves (57) to move closer to each other. This causes the bearing rings to be resuspended on the two conductive parts (56), and the lever (92) drives the actuating rod (93) to slide in the actuating plate (94), thereby driving the linkage turntable to rotate. Then, the local teeth (95) drive the ejector toothed rod (96) to move, thereby collecting the bearing rings on the two conductive parts (56) through the ejector head (97). After the teeth (95) have finished contacting, the spring (98) drives the ejector head (97) to reset, thereby facilitating the next bearing ring inspection process and improving convenience.
