Description

Technical Field

[0001] This utility model relates to the field of non-destructive testing technology for bearings, and in particular to a flat-lying bearing ring crack detection device. Background Technology

[0002] Bearing races consist of an outer ring and an inner ring, with rollers installed between them to ensure mutual rotation. In non-destructive testing of bearings, either the outer ring or the inner ring needs to be inspected separately.

[0003] like Figure 1 As shown, the existing technology involves an upper pressure roller pressing down on the bearing race via a cylinder, followed by a servo motor driving the spindle to rotate. Since the spindle and the rotating fixture are connected by screws, the spindle can drive the rotating fixture to rotate together. Because the upper pressure roller presses down on the bearing race, the bearing race and the rotating fixture are brought together, and under the action of friction, the bearing race also rotates. When the bearing race can rotate stably, the probe scanning unit drives the detection probe to complete the eddy current flaw detection of the bearing race surface.

[0004] Because there are many types and sizes of bearings, a different rotating fixture is needed each time the inner and outer rings of different bearing models are inspected. Users need to equip themselves with a set of rotating fixtures for each bearing size. Having many types of rotating fixtures makes it easy to make mistakes when changing bearings, and it's also troublesome to change bearings. The large number of changeover fixtures required also increases operating costs and affects economic efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a flat-lying bearing ring crack detection device to solve the problems encountered in the background art.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A horizontal bearing ring crack detection device includes a pressure roller mechanism, a platform roller mechanism, a drive wheel mechanism, a probe scanning mechanism, and a positioning wheel mechanism. The bearing ring is mounted on top of the platform roller mechanism, and the pressure roller mechanism is mounted on the upper part of the platform roller mechanism. The drive wheel mechanism, the probe scanning mechanism, and the positioning wheel mechanism are respectively mounted on one side of the platform roller mechanism. The positioning wheel mechanism includes a positioning fixing plate and a transmission module. The transmission module is linearly connected to the positioning fixing plate. Two positioning wheels are rotatably connected to the working end of the positioning fixing plate. When working, both positioning wheels abut against the outer circumferential surface of the bearing ring.

[0008] In the above scheme, the pressure roller mechanism includes a fixed beam, a first driving device, and a pressure roller frame. The fixed beam is installed on one side of the probe scanning mechanism, the first driving device is installed on the fixed beam, and the working end of the first driving device is connected to the pressure roller frame in the vertical direction through a first linear guide rail. The bottom of the pressure roller frame is provided with a pressure roller that abuts against the top of the bearing ring.

[0009] In the above scheme, the platform roller mechanism includes a working platform with first columns at four ends of the bottom. An alloy roller is rotatably mounted in the middle of the working platform, with its surface protruding outwards from the working platform. During operation, the bearing ring is located on top of the alloy roller. As a preferred embodiment, four alloy rollers are arranged on the working platform in a cross shape; during testing, the bearing ring rests on all the alloy rollers at its base.

[0010] In the above scheme, the drive wheel mechanism includes a second drive device, a main shaft plate, a rubber-coated wheel, and a first transmission device. The second drive device is installed on one side of the platform roller mechanism, and the working end of the second drive device is linearly connected to the main shaft plate in the horizontal direction through a second linear guide rail. The first transmission device is installed at the bottom of the main shaft plate, and its output end passes through the main shaft plate and is connected to the main shaft. The rubber-coated wheel is installed at the top of the main shaft.

[0011] As a preferred embodiment, the rubber-coated wheel is mounted on top of the spindle by a locking nut; the outer surface of the rubber-coated wheel is provided with an elastic layer.

[0012] In the above scheme, the probe scanning mechanism includes a second transmission device, a vertical conveying module, a horizontal conveying module, a third transmission device, an eddy current flaw detection probe, and a support frame. The support frame is installed on one side of the platform roller mechanism, and a backing plate is fixed on the top of the support frame. The second transmission device and the third transmission device are fixedly connected to the backing plate. The second transmission device is vertically arranged and its working end is connected to the vertical conveying module. The vertical conveying module and the horizontal conveying module are arranged in a cross shape. The horizontal conveying module is installed on the slide plate of the vertical conveying module. The third transmission device is horizontally arranged and its working end is connected to the horizontal conveying module. The eddy current flaw detection probe is installed on the slide plate of the horizontal conveying module.

[0013] As a preferred embodiment, the horizontal conveying module is further provided with a horizontal conveying slide, a vertical conveying slide, and a precision lifting platform in sequence on the slide plate, and the eddy current flaw detection probe is installed at the working end of the precision lifting platform.

[0014] In the above scheme, the positioning wheel mechanism also includes a second column and a fourth transmission device. The transmission module is installed on the second column, and the fourth transmission device is linearly connected to the transmission module through a coupling. Both positioning wheels are vertically arranged, and a slot is provided between the two positioning wheels.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The positioning wheel mechanism remains stationary during normal testing. It only adjusts when the bearing ring type is changed, moving back and forth according to the bearing ring's outer diameter using the fourth transmission device. A servo motor drives the transmission module via a coupling, converting rotary motion into linear motion. This allows the servo motor to drive the positioning wheel in a linear reciprocating motion, adjusting it to different bearing ring sizes to ensure the bearing ring's rotation center remains constant, thus adapting to different sizes of inner and outer rings. This solution is easier to debug than current technology, has a more compact structure, is more adaptable to different bearing ring sizes, and offers stronger changeover capabilities.

[0017] 2. The alloy rollers protrude beyond the work platform. During operation, the bearing race is positioned on top of the alloy rollers, and during testing, its bottom rests on all the alloy rollers. The four alloy rollers rotate with the bearing race, thus supporting it, limiting its downward movement, reducing the energy consumed by the bearing race's rotation, and preventing slippage. Furthermore, the use of polyurethane-coated wheels to drive the bearing race rotation increases the reliability of the rotation. Because polyurethane is a flexible material, it will not scratch the bearing race surface, protecting it during testing. This solution is more ingenious in structure, offers more stable performance, and saves customers costs compared to current technologies.

[0018] 3. This flat-lying bearing ring crack detection equipment has a simple overall structure, making it easy to maintain and debug. Combined with the existing PLC system, the changeover process does not require manual adjustment or replacement of parts, and the changeover can be done with one click, greatly improving production efficiency.

Detailed Implementation

[0028] To make the technical means, creative features, achieved objectives and effects of this utility model easier to understand, the utility model will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of this utility model, and therefore only show the relevant components of this utility model.

[0029] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0030] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] Example 1, such as Figure 2As shown, a horizontal bearing ring crack detection device includes a pressure roller mechanism 1, a platform roller mechanism 2, a drive wheel mechanism 3, a probe scanning mechanism 4, and a positioning wheel mechanism 5. This device can perform eddy current non-destructive testing on bearing rings, promptly feeding back any micro-cracks found to the system and rejecting unqualified bearing outer or inner rings.

[0032] The pressure roller mechanism 1 is used to press down the top of the bearing ring; the platform roller mechanism 2 is used to support the bottom of the bearing ring; the drive wheel mechanism 3 is used to drive the bearing ring to rotate; the probe scanning mechanism 4 is used to adjust the position of the eddy current testing probe 45 to match different models of bearing rings; the positioning wheel mechanism 5 changes its front and rear positions according to the different models of bearing rings to adapt to bearing rings of different diameters.

[0033] The bearing race is installed on top of the platform roller mechanism 2, and the pressure roller mechanism 1 is installed on the upper part of the platform roller mechanism 2. When the bearing race to be tested is placed on the platform roller mechanism 2, it is pressed down in time. The drive wheel mechanism 3, the probe scanning mechanism 4, and the positioning wheel mechanism 5 are respectively installed on one side of the platform roller mechanism 2, and each performs its own task to complete the adaptive adjustment for different types of bearing races.

[0034] Please refer to Figure 7 The positioning wheel mechanism 5 includes a positioning fixing plate 51 and a transmission module 53. The transmission module 53 is installed on one side of the platform roller mechanism 2 and can adopt a lead screw and nut mechanism. The transmission module 53 is linearly connected to the positioning fixing plate 51. The working end of the positioning fixing plate 51 is rotatably connected to two positioning wheels 52. When working, the two positioning wheels 52 abut against the outer circumferential surface of the bearing ring. Different types of bearing rings can be abutted by the two positioning wheels 52 to facilitate stable eddy current non-destructive testing at the abutting position, so as to check whether there is external damage or cracks on the bearing ring under test.

[0035] In addition, the positioning wheel mechanism 5 also includes a second column 54 and a fourth transmission device 55. The fourth transmission device 55 is a servo motor or a stepper motor. The four ends of the transmission module 53 are mounted on the second column 54, providing stable support. The fourth transmission device 55 is linearly connected to the transmission module 53 via a coupling 56. In practice, the coupling 56 can be connected to the lead screw of the lead screw and nut mechanism, and the nut can drive the positioning plate 51 to move back and forth.

[0036] Both positioning wheels 52 are vertically arranged, and there is a slot between the two positioning wheels 52. The whole structure is symmetrical and has a jaw shape, so that it can abut against the outer wall of the bearing ring during operation.

[0037] The positioning wheel mechanism 5 remains stationary during normal testing. Only when the bearing race type is changed, the positioning wheel 52, in conjunction with the fourth transmission device 55, moves back and forth to adjust according to the outer diameter of the bearing race, facilitating the testing of the replaced bearing race. The servo motor drives the transmission module 53 via the coupling 56, converting the rotary motion into linear motion.

[0038] The positioning wheel 52, the positioning wheel shaft, and the bearing form a rotary positioning mechanism. When the outer diameter of the bearing ring is tangent to both positioning wheels 52 simultaneously, the displacement of the bearing ring is restricted. This rotary positioning mechanism is fixed on the positioning fixing plate 51, which in turn is fixed on the transmission module 53. In this way, the servo motor can drive the positioning wheel 52 to reciprocate in a linear direction. The positioning wheel 52 can be adjusted according to the bearing rings of different sizes to ensure that the rotation center of the bearing ring remains unchanged.

[0039] Therefore, it can be said that the positioning wheel mechanism 5 can move the positioning wheel 52 back and forth according to the bearing rings of different sizes, and the servo motor controls the transmission module 53 to adapt to the inner and outer rings of bearings of different sizes.

[0040] Example 2, based on Example 1, provides a horizontal bearing ring crack detection device, such as... Figure 3 As shown, the lower pressure roller mechanism 1 includes a fixed beam 11, a first drive device 12, and a pressure roller frame 14. The fixed beam 11 is installed on one side of the probe scanning mechanism 4. The first drive device 12 is a cylinder or an electric cylinder. The first drive device 12 is installed on the fixed beam 11. The working end of the first drive device 12 is connected to the pressure roller frame 14 in the vertical direction through the first linear guide rail 13. When the first drive device 12 moves, it drives the pressure roller frame 14 to move up and down. The bottom of the pressure roller frame 14 is provided with a lower pressure roller 15 that abuts against the top of the bearing ring. The lower pressure roller 15 is arranged horizontally and rotatably connected to the bottom of the pressure roller frame 14.

[0041] The operation flow of the lower pressure roller mechanism 1 is as follows: ① The bearing ring is positioned; ② The first drive device 12 actuates, and the lower pressure roller 15 presses against the bearing ring; ③ The servo motor in the drive wheel mechanism 3 starts; ④ The bearing ring rotates; ⑤ Inspection completed; ⑥ The servo motor in the drive wheel mechanism 3 stops, and the rubber-coated roller 35 stops rotating; ⑦ The first drive device 12 actuates, and the lower pressure roller 15 disengages from the bearing ring. Because the first drive device 12 is fixed on the fixed beam 11, and the pressure roller frame 14 and the fixed beam 11 are connected by the first linear guide rail 13, it is ensured that the lower pressure roller 15 can reciprocate in the vertical direction.

[0042] Example 3, based on Example 1, describes a horizontal bearing ring crack detection device. Because existing rotating fixtures are machined from metal, and the inner and outer rings of the bearing are mostly made of bearing steel, the coefficient of friction between them is low, resulting in less frictional force and a tendency to slip during rotation. Since existing rotating fixtures are machined from metal, once slippage occurs, the fixture easily leaves scratches on the metal surfaces of the bearing's inner and outer rings, increasing the scrap rate and impacting economic efficiency.

[0043] like Figure 4 As shown, the platform roller mechanism 2 includes a working platform 21. First columns 23 are fixed to the four ends of the bottom of the working platform 21. Alloy rollers 22 are rotatably mounted in the middle of the working platform 21. The wheel surfaces of the alloy rollers 22 protrude outwards from the working platform 21. During operation, the bearing rings are located on top of the alloy rollers 22. During testing, the bottom of the bearing rings rests on all the alloy rollers 22. As a preferred embodiment, four alloy rollers 22 are arranged on the working platform 21 in a cross shape to provide overall support for the outer circumference of the bearing rings.

[0044] During implementation, four slots are cut into the workstation platform 21, and then the alloy roller 22 is assembled onto the workstation platform 21 in conjunction with the bearing and shaft. The function of this platform roller mechanism 2 is to support the inner and outer rings of the bearing and assist in their rotation. When the equipment starts testing, the lower roller 15 of the lower roller mechanism 1 forces the inner and outer rings of the bearing to press against the alloy roller, enabling it to rotate stably.

[0045] By cutting four elongated slots on the workstation platform 21, it is ensured that the four alloy rollers 22 can be installed precisely within them without obstruction during rotation. The alloy rollers 22, together with the bearings and shafts, form a rotating mechanism that can follow the movement of the bearing race. When a bearing race arrives at the inspection station, the four alloy rollers 22 can steadily support the bearing race, and as the bearing race is driven to rotate, the four alloy rollers 22 can rotate along with the bearing race. This not only supports the bearing race and restricts its downward movement, but also reduces the consumption of the bearing race's rotational kinetic energy, preventing slippage during rotation.

[0046] Example 4, based on Example 3, provides a horizontal bearing ring crack detection device. Please refer to [link / reference]. Figure 5 The drive wheel mechanism 3 includes a second drive device 31, a main shaft plate 32, a rubber-coated wheel 35, and a first transmission device 37. The second drive device 31 is a pneumatic cylinder or an electric cylinder. The second drive device 31 is installed on one side of the platform roller mechanism 2, which can be installed on the side of the workstation platform 21. The working end of the second drive device 31 is connected to the main shaft plate 32 in a linear transmission in the horizontal direction through the second linear guide rail 33, which can move the entire rubber-coated wheel 35 as a whole.

[0047] The first transmission device 37 can be a servo motor or a stepper motor. The first transmission device 37 is installed at the bottom of the spindle plate 32, and its output end passes through the spindle plate 32 and is connected to the spindle 34. The rubber-coated wheel 35 is installed on the top of the spindle 34. When the first transmission device 37 rotates, it drives the rubber-coated wheel 35 to rotate together. Because the rubber-coated wheel 35 abuts against the bearing ring when working, it forces the bearing ring to rotate together.

[0048] As a preferred embodiment, the rubber-coated wheel 35 is mounted on top of the main shaft 34 via a locking nut 36; the outer surface of the rubber-coated wheel 35 is provided with an elastic layer made of polyurethane polymer material. A first transmission device 37 provides rotational kinetic energy, causing the main shaft 34 to rotate via a coupling. Because the main shaft 34 and the rubber-coated wheel 35 are connected by the locking nut 36, the rubber-coated wheel 35 can be driven to rotate by the first transmission device 37.

[0049] The horizontal bearing ring crack detection equipment in this solution uses a polyurethane-coated wheel 35 to drive the bearing ring to rotate. The high coefficient of friction between polyurethane and steel generates significant frictional force, preventing the bearing ring from slipping during rotation. Furthermore, because polyurethane is a flexible material, it will not scratch the bearing ring surface, thus protecting the bearing ring during the detection process.

[0050] The operation flow of this drive wheel mechanism 3 is as follows: ① The bearing ring is in place; ② The second drive device 31 is activated; ③ The first transmission device 37 is started; ④ The rubber-coated wheel 35 drives the bearing ring to rotate; ⑤ The inspection is completed; ⑥ The first transmission device 37 stops; ⑦ The rubber-coated wheel 35 stops rotating; ⑧ The second drive device 31 is activated and the rubber-coated wheel 35 disengages from the bearing ring.

[0051] During testing, the second drive device 31 pulls the main shaft plate 32. Because the main shaft plate 32 is fixed by the second linear guide rail 33, the rubber-coated wheel 35 can stably perform linear reciprocating motion. The first transmission device 37 drives the main shaft 34 to rotate via a coupling. At the same time, the main shaft 34 and the rubber-coated wheel 35 are connected by a locking nut 36, so the first transmission device 37 indirectly drives the rubber-coated wheel 35 to rotate. Since the second drive device 31 is pulling the main shaft plate 32, the rubber-coated wheel 35 and the bearing ring can make good contact, and the friction generated between them can also drive the ring to rotate.

[0052] Example 4, based on Examples 1-3, provides a horizontal bearing ring crack detection device. Please refer to [link / reference]. Figure 6The probe scanning mechanism 4 includes a second transmission device 41, a vertical conveying module 42, a horizontal conveying module 43, a third transmission device 44, an eddy current flaw detection probe 45, and a support frame 49. Both the second transmission device 41 and the third transmission device 44 can be servo motors or stepper motors, and both the vertical conveying module 42 and the horizontal conveying module 43 can be lead screw and nut mechanisms. However, the vertical conveying module 42 is used for longitudinal conveying, and the horizontal conveying module 43 is used for transverse conveying.

[0053] A support frame 49 is installed on one side of the platform roller mechanism 2. A backing plate is fixed to the top of the support frame 49. The second transmission device 41 and the third transmission device 44 are fixedly connected to the backing plate to provide support for its drive. The second transmission device 41 is vertically arranged and its working end is connected to the vertical conveying module 42. The vertical conveying module 42 and the horizontal conveying module 43 are arranged in a cross shape. The horizontal conveying module 43 is installed on the slide plate of the vertical conveying module 42. The third transmission device 44 is horizontally arranged and its working end is connected to the horizontal conveying module 43. The eddy current flaw detector 45 is installed on the slide plate of the horizontal conveying module 43.

[0054] The second transmission device 41 drives the horizontal transmission module 43 and the eddy current flaw detector 45 to move linearly in the vertical direction through the vertical transmission module 42. The third transmission device 44 drives the eddy current flaw detector 45 to move linearly in the horizontal direction through the horizontal transmission module 43, so that the eddy current flaw detector 45 can be adjusted in the vertical direction and the horizontal direction according to the position of the bearing ring.

[0055] As a preferred embodiment, the horizontal conveying module 43 is also provided with a horizontal conveying slide 46, a vertical conveying slide 47, and a precision lifting platform 48 in sequence on the slide plate. The eddy current flaw detection probe 45 is installed at the working end of the precision lifting platform 48. Through multiple conveying slides, it can make micro-adjustments in the vertical Z-axis direction, the horizontal X-axis direction, and the front and back Y-axis direction. It can also automatically adjust a certain distance to prevent collision with hard objects and protect the probe.

[0056] In this probe scanning mechanism 4, two transmission devices drive the conveying module through a coupling, converting the rotary motion into linear motion. The vertical conveying module 42 controls the probe to move up and down in the vertical direction, and the horizontal conveying module 43 controls the probe to move in the horizontal direction. In this way, the eddy current flaw detection probe 45 can reach any point on this plane, thereby enabling contour scanning inspection of the bearing ring surface.

[0057] The scanning mechanism 4 of the probe has two returnable slides, one that can move horizontally and the other vertically. The eddy current testing probe 45 is a precision instrument; a collision between the eddy current probe and the collar can cause significant damage. Therefore, returnable slides are added in both directions. When the probe collides with any object in any direction, the slides will shift, triggering a proximity switch to disconnect the signal. The PLC then receives a feedback signal indicating a collision with the eddy current probe, causing the equipment to stop and alarm. This protects the eddy current testing probe 45 while allowing the operator to inspect the equipment and eliminate any abnormalities.

[0058] Based on the solutions in Examples 1-4, when changing the original equipment, the rotating tooling needs to be replaced. The positioning wheel 52 of the new equipment is controlled by the fourth transmission device 55, and the PLC automatically adjusts it according to the outer diameter of the bearing ring. At the other end, the second drive device 31 controls the rubber-coated wheel 35 to press the outer diameter of the bearing ring. The operator only needs to retrieve the formula of the model to be produced in the PLC, realizing a true one-click model change. In addition, this equipment also has anti-collision protection for the eddy current probe, protecting the precision instruments inside the equipment. This equipment not only has a high degree of automation, but also high detection accuracy and efficiency. Therefore, this equipment has significantly improved operability and economy compared with existing technologies, surpassing existing equipment at home and abroad.
