Description

Technical Field

[0001] The present invention relates to the technical field of nondestructive testing, in particular to a full-automatic eddy current nondestructive testing device for surface cracks of a vertical bearing ring. Background Art

[0002] A bearing consists of an inner ring, an outer ring and balls. The existing technology is that the bearing ring to be inspected is rotated by a belt, and then two probes are controlled by a cylinder to perform flaw detection on the rotating bearing ring.

[0003] When a belt drives the bearing ring, the smooth belt surface creates less friction, leading to slippage between the belt and the bearing ring, which can affect the inspection results. This friction is also common, leading to belt breakage and the need for frequent replacement, which can negatively impact cost-effectiveness.

[0004] Furthermore, the belt is tensioned by a tension spring. As the motor drives the belt to rotate, the instability of the tension spring causes the tension on the belt to be unstable, causing the belt to jump up and down. Because of this belt jitter, the bearing ring driven by the belt will also jump during rotation, seriously affecting the detection effect. Summary of the Invention

[0005] The object of the present invention is to provide a fully automatic eddy current detection device for vertical bearing rings to solve the problems encountered in the above-mentioned background technology.

[0006] To achieve the above object, the technical solution of the present invention is as follows:

[0007] A fully automatic eddy current testing device for a vertical bearing ring includes a workbench, a pressure wheel assembly and a flaw detection mechanism. The pressure wheel assembly is installed on the workbench and its working end is located at the detection station. The pressure wheel assembly includes a support plate and a driving wheel. The driving wheel is installed on one side of the bottom of the support plate and drives the bearing ring to rotate at the detection station. The pressure wheel assembly presses down on the outer ring of the bearing ring by driving the driving wheel downward. The flaw detection mechanism is installed on the workbench and its probe is located at the detection station.

[0008] In the above solution, the pressure wheel assembly further includes a driven wheel, which is mounted on the other side of the bottom of the support plate. The pressure wheel assembly drives the driven wheel to move downward to press down on the outer ring of the bearing ring.

[0009] In the above solution, the pressure wheel assembly further includes a follower, which is installed in the middle of the bottom of the support plate. The pressure wheel assembly drives the two followers to clamp inward to perform contact limiting on both sides of the bearing ring.

[0010] In the above solution, a first driving module is provided on the back of the support plate for driving the various motion execution devices on the front and the support plate itself.

[0011] In the above scheme, the flaw detection mechanism includes an outer diameter flaw detection device, an inner diameter flaw detection device and a bracket. The working end of the outer diameter flaw detection device and the working end of the inner diameter flaw detection device are respectively installed with probes, and the outer diameter flaw detection device and the inner diameter flaw detection device are respectively freely moved on the bracket through the flaw detection drive assembly.

[0012] In the above solution, the outer diameter flaw detection device and the inner diameter flaw detection device are respectively installed with anti-collision components.

[0013] Compared with existing technologies, the present invention offers the following advantages: This device utilizes a rubber-coated driving wheel to drive the bearing ring. Because the rubber-coated driving wheel is highly wear-resistant, it does not require frequent replacement, thus resolving the issue of frequent belt replacement. Furthermore, because the rubber-coated driving wheel's pressure against the bearing ring is controlled by a cylinder, the cylinder's stability ensures a steady pressure on the bearing ring, preventing the bearing ring from bouncing during rotation.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention will now be further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the relevant components of the present invention.

[0030] According to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art may propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific embodiments and drawings are merely illustrative of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the present invention.

[0031] The technical solution of the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0032] Example 1, as Figures 1 to 3 、 Figure 5 、 Figure 10 As shown, a fully automatic eddy current detection device for vertical bearing rings includes a workbench 1, a pressure roller assembly 3 and a flaw detection mechanism 4. The pressure roller assembly 3 is installed in the workbench 1 and its working end is located at the detection station. The pressure roller assembly 3 includes a support plate 31, a driving wheel 32 and a first cylinder 33. The driving wheel 32 is installed on the bottom side of the support plate 31 and drives the bearing ring to rotate at the detection station. The pressure roller assembly 3 drives the driving wheel 32 to move downward to press down on the outer ring of the bearing ring. The driving wheel 32 is rubber-coated to improve wear resistance. The flaw detection mechanism 4 is installed in the workbench 1 and its probe is located at the detection station to detect the bearing ring placed at the detection station. The support plate 31 can be installed vertically in the chassis 8 or installed obliquely in the chassis 8.

[0033] A first cylinder 33 is mounted obliquely downward on the support plate 31. The first cylinder 33 pushes the driving wheel 32 downward, producing a linear motion obliquely downward. A servo motor, mounted on the mounting plate where the driving wheel 32 is mounted, drives its rotation. This servo motor is one of the drive units in the first drive module 38. The rotation of the driving wheel 32 in turn drives the bearing ring to rotate. This contact method not only locates the bearing ring but also drives its rotation, facilitating nondestructive testing.

[0034] See also Figures 5 to 7 The pressure roller assembly 3 also includes a driven wheel 34 and a second cylinder 35. The driven wheel 34 is mounted on the other side of the bottom of the support plate 31. The pressure roller assembly 3 drives the driven wheel 34 downward to press down on the outer ring of the bearing ring. The second cylinder 35 is mounted obliquely downward on the support plate 31. The driven wheel 34 is driven by the second cylinder 35. The first cylinder 33 and the second cylinder 35 form an inverted figure-eight structure, which can clamp and limit the outer ring of the bearing ring on both sides and can be driven to rotate by the driving wheel 32. The driven wheel 34 limits the rotation position of the bearing ring, preventing it from shifting.

[0035] As a preferred embodiment, the pressure roller assembly 3 also includes a follower 36 and a bilateral module 37. The follower 36 is mounted in the center of the bottom of the support plate 31. The pressure roller assembly 3 drives the two followers 36 inward to clamp and limit the contact between the two sides of the bearing ring. The two followers 36 are driven separately by two parallel bilateral modules 37, clamping and contacting the two sides of the bearing ring to be tested, limiting their movement. In addition, the bilateral module 37 and the follower 36 can also move vertically downward or upward linearly under the action of the drive device.

[0036] As a preferred solution, a first drive module 38 is installed on the back of the support plate 31. The first drive module 38 can be installed on the inner wall of the chassis 8 via screws. The first drive module 38 provides driving force for the device on the front of the support plate 31 to move up and down, conveniently adapting to bearing rings of various types and sizes. For example, the first drive module as a whole drives the driving wheel 32, the driven wheel 34, and the follower 36 to move up and down on the front of the support plate 31, so that the surface of each wheel body contacts the outer ring of the bearing ring. Therefore, the drive unit in the first drive module 38 is used to drive the driving wheel 32 to rotate, and is also responsible for the overall adjustment of the entire support plate 31 and the equipment installed on the support plate 31.

[0037] The pressure wheel assembly 3 is the biggest highlight of the improvement of this equipment. The existing equipment uses a belt to drive the bearing ring to rotate, and now a pressure wheel is used instead of a belt to drive the bearing ring to rotate. The advantages of the pressure wheel drive method are small vibration, stable equipment operation, and a long service life of the rubber-coated active wheel 32, which does not require frequent replacement. The fixing method for clamping the end face follower of the bearing ring on the equipment is designed to be fixed on the bilateral module 37, and the distance between the followers 36 is controlled by a servo motor. In this way, not only does the operator not need to make manual adjustments during the model change, saving a lot of model change time, but it also solves the problem of the screws loosening after the equipment has been used for a period of time, causing the follower 36 to loosen, resulting in excessive gaps in the follower 36, and the bearing ring jumping particularly large during rotation, seriously affecting the detection of the probe.

[0038] During the operation of the pressure roller assembly 3, the operator switches the model of the bearing ring to be inspected on the operation panel 81. The servo motor controls the first drive module 38 to automatically adjust the support plate 31 up and down to the working position for inspecting the bearing ring of that model based on the bearing ring model. Similarly, the servo motor of the first drive module 38 also drives the bilateral module 37 up and down, which controls the distance between the followers 36 to match the thickness of the different bearing ring models to be inspected. The bearing ring is then rotated from the holding position to the inspection position under the control of the positioning turntable assembly 2. The cylinder below the bilateral module 37 then activates, causing the followers 36 to secure the two end faces of the bearing ring, thereby limiting its forward and backward movement. Simultaneously with the activation of the cylinder below the bilateral module 37, the first and second cylinders 33 and 35 also operate simultaneously, pressing the driving wheel 32 and the driven wheel 34 against the outer diameter of the bearing ring, respectively, creating a multi-point positioning mechanism that secures the bearing ring in the inspection position. Finally, the servo motor where the driving wheel 32 is located is started to drive the driving wheel 32 to rotate. Since the driving wheel 32 and the bearing ring are in contact and there is friction between them, the driving wheel 32 can drive the bearing ring to rotate at the detection station.

[0039] See also Figure 8The flaw detection mechanism 4 includes an outer diameter flaw detection device 41, an inner diameter flaw detection device 42, and a bracket 43. The working ends of the outer diameter flaw detection device 41 and the inner diameter flaw detection device 42 are respectively equipped with probes. The outer diameter flaw detection device 41 detects the outer diameter of the bearing ring using the probe, and the inner diameter flaw detection device 42 detects the inner diameter of the bearing ring using the probe. The outer diameter flaw detection device 41 and the inner diameter flaw detection device 42 are respectively freely movable on the bracket 43 via a flaw detection drive assembly 44. The flaw detection drive assembly 44 is composed of multiple sets of drive elements in different directions, which can achieve large-scale left-right linear movement, front-back linear movement, and up-down linear movement, allowing the probe to move freely in the three directions of X, Y, and Z. The movement distance can be measured in centimeters. When the support plate 31 is installed at an angle in the chassis 8, it forms a state of oblique up-down linear movement. Therefore, large-scale front-back linear movement and oblique up-down linear movement can also be achieved, allowing the probe to move freely in the two directions of X and Z.

[0040] The main function of the flaw detection mechanism 4 is to control the inner diameter probe and the outer diameter probe to perform full coverage scanning and flaw detection on the inner diameter, outer diameter, inner and outer end faces, grooves, and inner and outer chamfers of the bearing ring. The probe of the existing equipment is controlled by a cylinder, and the flaw detection range is small. It cannot fully cover the bearing ring for flaw detection, which is easy to cause missed detection and will cause significant losses to users. When the existing equipment is changed, the probe controlled by the cylinder needs to adjust the installation position of the probe according to the different types of bearing rings. This cumbersome operation wastes a lot of labor costs and time costs for the company. The probe in this device is controlled by a combination of a servo motor and a flaw detection drive component 44. It will automatically adjust according to the model of the bearing ring being inspected, realizing one-click change.

[0041] The probes in existing equipment lack anti-collision mechanisms. In the event of an accident or operator error, the probes could collide with the equipment or bearing rings, potentially breaking or wearing out the probes. Imported probes are expensive and require a long procurement cycle, increasing costs for the company. Therefore, in this device, anti-collision components 45 are installed in both the outer diameter flaw detection device 41 and the inner diameter flaw detection device 42.

[0042] See also Figure 8 and Figure 9 The anti-collision assembly 45 includes a slide 451 and a first sensor 452. The slide 451 is mounted on top of the flaw detection drive assembly 44. At least one first sensor 452 is installed on the side of the slide 451. The top of the slide 451 secures the probe via a fixing rod 46. The first sensor 452 is designed to prevent collisions with other components of the equipment or bearing rings during movement of the flaw detection drive assembly 44 and the slide 451. Two first sensors 452 can be provided, positioned at right angles, to detect left-right or forward-backward motion.

[0043] The fixed rod 46 can be an L-shaped structure or a straight rod structure to facilitate the transportation of the probe. The slide 451 is composed of multiple sets of driving elements in different directions, which can realize small-scale left and right linear movement, front and back linear movement, and up and down linear movement, realizing the free movement of the probe in the three directions of XYZ, and the moving distance can be calculated in millimeters. When the support plate 31 is installed obliquely in the chassis 8, it forms a state of oblique up and down linear movement, so it can also realize large-scale front and back linear movement, oblique up and down linear movement, realizing the free movement of the probe in the two directions of XZ.

[0044] The new equipment uses a probe anti-collision component 45 to prevent damage to the probe after an accident or misoperation. The detection mechanism is mainly composed of an aluminum profile detection mechanism bracket 43, an outer diameter and inner diameter flaw detection drive component 44. When the anti-collision component 45 is working, when the probe is hit in the Z direction, because the probe is fixed on the slide 451, there is a tension spring inside the upper slide 451, and the upper half of the slide 451 is movable, the upper half of the slide 451 will move in the Z direction when a collision occurs. At the same time, the first sensor 452 also moves in the Z direction. The first sensor 452 loses the signal, the equipment alarms and stops running, thereby effectively protecting the probe. Similarly, when the probe is hit in the X direction, the upper half of the slide 451 in the middle is offset in the X direction, and the other first sensor 452 loses the signal, the equipment alarms and stops running.

[0045] The structures of the outer diameter flaw detection device 41 and the inner diameter flaw detection device 42 are similar, and the outer diameter flaw detection device 41 will be used as an example for explanation. The operating principle of the outer diameter flaw detection device 41 is as follows: After the bearing ring arrives at the inspection station, the first servo motor in the flaw detection drive assembly 44 is activated. This controls the left-right modules via a synchronous pulley and a synchronous belt, allowing the outer diameter probe to move in the front-to-back direction. Simultaneously, after the station, the second servo motor in the flaw detection drive assembly 44 is activated, controlling the front-to-back modules via a coupling, allowing the outer diameter probe to also move in the left-to-right and front-to-back directions. This allows the outer diameter probe to move freely in both the left-to-right and front-to-back directions, allowing it to follow a rough contour path along the outer surface of the bearing ring, following the outer shape and structure of the bearing ring, while also performing a full-coverage scanning inspection of the outer diameter, inner end face, and inner chamfer of the bearing ring. Similarly, the inner diameter probe in the inner diameter flaw detection device 42, also implemented using the above method, can also move freely in both the left-to-right and front-to-back directions, following a contour path along the inner surface of the bearing ring, thus performing a full-coverage scanning inspection of the inner diameter, outer end face, and outer chamfer of the bearing ring. When the support plate 31 is installed obliquely in the chassis 8, the up and down movement will automatically form an oblique up and down linear movement state to meet the needs of bearing ring detection.

[0046] See also Figure 10The equipment in the workbench 1 is mounted inside the chassis 8. An operation panel 81 is mounted on one side of the chassis 8 via a movable rod. The main control system of the operation panel 81 is generally a PLC control system, which is a common control system for automated equipment. This allows workers to easily operate and control the operation of various devices or mechanisms. Furthermore, an alarm 82 is installed on the top of the chassis 8 to promptly sound an alarm in the event of a malfunction in any of the devices or mechanisms on the workbench 1.

[0047] Example 2, based on Example 1, please refer to Figure 1 and Figure 4 The fully automatic eddy current testing equipment for vertical bearing rings also includes a positioning turntable assembly 2, which is installed on one side of the workbench 1 close to the testing station and is used to position and transport the bearing ring to be tested.

[0048] The positioning turntable assembly 2 includes a drive motor 21 and a turntable 22. The drive motor 21 is installed on the workbench 1. The drive motor 21 is connected to the turntable 22 through a divider 24. The divider 24 can adopt a cam divider of model ENRADEX to divide the turntable 22 at a certain angle so that it can be stably docked at the inspection station.

[0049] Multiple sets of positioning wheels 23 are evenly fixed on the outer periphery of the turntable 22. Each positioning wheel 23 is made of hard alloy. Each set of positioning wheels 23 can position the bearing ring. In addition, each set of positioning wheels 23 is provided with two positioning wheels 23. The two positioning wheels 23 in this set can also position the bearing ring. Figure 4 As shown, the distance between the two positioning wheels 23 is shorter, which can be used to transport small-sized bearing rings, while the distance between the two sets of positioning wheels 23 is longer, which can be used to transport large-sized bearing rings. Therefore, one positioning turntable assembly 2 can transport two types of bearing rings with very different diameters without the need to replace the turntable 22.

[0050] The main function of the positioning turntable assembly 2 is to transfer the bearing ring from the waiting station to the inspection station and precisely position the bearing ring using the driven positioning wheel 23. The operating principle is as follows: After the bearing ring enters the waiting station, the drive motor 21 is activated to rotate the divider 24, thereby driving the turntable 22 to rotate. The bearing ring is transferred from the waiting station to the inspection station. The turntable has two gears. When testing large rings, the drive motor 21 controls the angle of the turntable 22 so that the large ring enters the gear with a larger span of the positioning driven wheel 23. When testing small rings, the drive motor 21 controls the angle of the turntable 22 so that the small ring enters the gear with a smaller span of the positioning driven wheel 23. The driven wheel 23 used for positioning and transfer in this equipment is made of cemented carbide, which has a hardness and wear resistance far greater than that of ordinary plastic driven wheels. Because cemented carbide has excellent wear resistance, it does not need to be replaced, greatly saving labor and material costs.

[0051] When the positioning turntable assembly 2 is engaged with the pressure roller assembly 3 and the flaw detection mechanism 4, the bearing ring in the inspection station has arrived at the inspection station. The bearing ring is fixed at six points by the driving wheel 32, the driven wheel 34, the two followers 36, and the two positioning driven wheels 23. The driving wheel 32 on the pressure roller assembly 3 then rotates the bearing ring. The six-point positioning ensures smooth rotation without jerking. Finally, the inner and outer diameter probes, controlled by servo motors, perform a full-coverage scanning flaw detection on the bearing ring.

[0052] Example 3, based on Example 1 or 2, please refer to Figure 10 、 Figure 11 and Figure 13 , further comprising an inlet channel 5 and an outlet channel 7. The inlet channel 5 is mounted on one side of the workbench 1, and the outlet channel 7 is mounted on the other side of the workbench 1. Each of the inlet channel 5 and the outlet channel 7 is provided with a drive device for adjusting the channel width. The drive device is a second drive module 51. Driven by the second drive module 51, the distance between the baffles on both sides of the inlet channel 5 or the outlet channel 7 can be adjusted to widen or narrow it to match the appropriate bearing ring. The output end of the inlet channel 5 is located at the inspection station, and the input end of the outlet channel 7 is located at the inspection station.

[0053] Example 4, based on Example 1 or 2 or 3, please refer to Figure 12 A discharge mechanism 6 is provided at the top of the inlet channel 5. The discharge mechanism 6 blocks the bearing rings conveyed on the inlet channel 5 to prevent the continuously input shaft rings from interfering with the bearing rings being tested.

[0054] The discharge mechanism 6 includes a third drive module 61, a mounting plate 62 and a material distribution tray 64. The third drive module 61 is installed on the workbench 1. The third drive module 61 is transmission-connected to the mounting plate 62. The mounting plate 62 is rotationally connected to the material distribution tray 64. A drive component for driving the material distribution tray 64 to rotate is installed on the back of the mounting plate 62. The drive component is a material distribution motor 63.

[0055] The working end of the material distribution plate 64 is provided with a material blocking opening 65. This arc-shaped opening is used to match the outer diameter of the bearing ring to limit the movement of the bearing ring. For example, when the material blocking opening 65 is fixed on the outer diameter of the bearing ring, or when the two side tips abut against the outer diameter of the bearing ring and remain stationary, it has the function of preventing the bearing ring from being transported and moved. A second sensor 66 can be installed on one side of the material distribution plate 64 to monitor the incoming material of the bearing ring so that the material distribution plate 64 can respond in a timely manner.

[0056] To ensure easy operation and simple model changeover of the fully automatic eddy current testing equipment for vertical bearing rings, a third drive module 61, consisting of a servo motor and a module combination, is used at the entrance to control the vertical movement of the distribution plate 64, while the distribution motor 63 controls the rotation angle of the distribution plate 64. Using this structure of the discharge mechanism 6, when changing bearing models, one only needs to switch the bearing ring model on the operation panel 81 to achieve a one-touch model change, saving time and effort while also ensuring accurate control.

[0057] This vertical bearing fully automatic eddy current testing equipment has many advantages over existing equipment, mainly including:

[0058] This device uses a rubber-coated driving pulley 32 to drive the bearing ring. Because the rubber-coated driving pulley 32 is highly wear-resistant, it eliminates the need for frequent belt replacement. Furthermore, because the rubber-coated driving pulley 32's pressure against the bearing ring is controlled by a pneumatic cylinder, the cylinder's stability ensures a steady pressure on the bearing ring, preventing the bearing ring from bouncing during rotation.

[0059] This equipment uses carbide rollers, which are extremely wear-resistant, eliminating the need to replace the positioning driven wheel 34, significantly saving manpower and material resources. A servo motor and module combination controls the movement of the probe. Because the travel and speed of the servo motor and module are controllable, the probe can scan and inspect the entire bearing ring.

[0060] The flaw detection probe in this equipment is fixed to the module. Because the module is controlled by a servo motor, the PLC remembers the detection position of different bearing ring models. Therefore, when changing models, the operator only needs to switch models on the operation panel 81. This convenient operation and simple model change truly realize one-click model change and fully automatic detection. In addition, this equipment uses a probe anti-collision component 45 to protect the probe from collisions during the inspection process, thereby reducing probe damage and eliminating unnecessary waste for the enterprise. All components in this equipment that require model change and adjustment are installed on the module and controlled by a servo motor. The external PLC automatically adjusts the working position of each component according to the bearing ring model, thus realizing true one-click model change.

[0061] In summary, this equipment not only has a high degree of automation, but also high detection accuracy and efficiency. This makes this case significantly better than existing technologies in terms of operability and economy, surpassing existing non-destructive eddy current testing equipment for bearings.
