Description

Technical Field

[0001] This invention relates to the field of bearing testing technology, and in particular to an intelligent sensing bearing fault diagnosis device. Background Technology

[0002] With the rapid development of modern industry, bearings, as an indispensable and important component in mechanical equipment, directly affect the reliability and stability of the equipment. In actual production, bearing failure can lead to equipment downtime and even safety accidents, causing huge economic losses. Therefore, accurate and efficient fault diagnosis of bearings is of utmost importance.

[0003] Application number CN202323110686.3 discloses a bearing fault diagnosis device, including a base. A variable frequency motor is fixedly installed at one upper end of the base, and a support frame is fixedly installed at the other upper end of the base. An installation mechanism is provided on the support frame. The installation mechanism includes two cylinders, which are vertically fixedly installed on both sides of the top of the support frame. A screw is located at the top of the support frame between the two cylinders. This utility model, by setting an installation mechanism and a bearing seat at the support frame position, uses the installation mechanism to fix the position of the bearing seat and can also adjust the position of the bearing seat, thereby ensuring that the internal center of the bearing seat is always on the same center line as the output end of the motor and the coupling. The bearing seat allows for quick installation of the bearing on this center line, and by replacing the bearing seat with one of the appropriate size according to the bearing size, it can support bearings of different sizes.

[0004] Based on the above patent searches and understanding of the application of existing bearing fault diagnosis devices: 1. During the bearing fault diagnosis process, it is difficult to accurately fix and position the bearing, which affects the accuracy of the test results and makes it impossible to accurately determine whether the bearing has a fault and the specific nature of the fault. 2. Existing bearing fault diagnosis devices have a low degree of automation. They require a lot of manual intervention in the processes of bearing transportation, testing, and collection of faulty bearings, which increases labor costs and reduces testing efficiency.

[0005] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an intelligent induction bearing fault diagnosis device in order to achieve a more practical purpose. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides an intelligent induction bearing fault diagnosis device. This addresses the issues of existing bearing fault diagnosis methods, such as the difficulty in accurately fixing and positioning the bearing during the fault diagnosis process, which affects the accuracy of the detection results and makes it impossible to precisely determine whether the bearing has a fault and the specific nature of the fault. Furthermore, existing bearing fault diagnosis devices have a low degree of automation, requiring significant manual intervention in the bearing transportation, detection, and collection of faulty bearings, increasing labor costs and reducing detection efficiency.

[0007] This invention provides an intelligent induction bearing fault diagnosis device, specifically comprising: a device frame; an extension frame fixedly installed at the upper rear end of the device frame, an electrical box fixedly installed at the top of the extension frame, a bracket fixedly installed at the right front end of the electrical box, a detection cylinder fixedly connected to the bottom front end of the bracket, a motor frame fixedly installed at the bottom of the detection cylinder, a motor A fixedly installed inside the motor frame, a detection frame fixedly installed on the bottom shaft of motor A, the detection frame being located below the motor frame, a bevel gear ring rotatably connected to the middle of the inside of the detection frame, a detection motor fixedly installed at the front end of the detection frame, a bevel gear on the shaft of the detection motor meshing with the bevel gear ring, a spiral thread at the bottom of the bevel gear ring, three sliding grooves at the bottom of the detection frame, the three sliding grooves of the detection frame being Y-shaped, a fitting component slidably connected in each of the three sliding grooves of the detection frame, all three fitting components being L-shaped, and an arc-shaped thread at the top of each fitting component, the arc-shaped threads of the three fitting components meshing with the spiral thread at the bottom of the bevel gear ring.

[0008] Furthermore, a controller is fixedly installed at the front center of the device frame, a collection rack is fixedly installed at the upper inside of the device frame, an operating table is fixedly installed at the top center of the device frame, a conveyor is set at the front of the operating table, a separator is set at the middle of the conveyor, and bearing components are placed at the top right side of the conveyor.

[0009] Furthermore, a docking platform is provided at the top right front end of the operating table. The docking platform is located directly below the detection frame, and the top of the docking platform is flush with the top of the conveyor.

[0010] Furthermore, a delivery machine is provided at the top left front end of the operating table. The delivery machine has an arc-shaped design, and the top of the delivery machine is flush with the top of the docking table.

[0011] Furthermore, cylinder A is installed at the front right side of the conveyor, and cylinder A is located at the front end of the docking platform. Cylinder B is installed at the right front of the operating platform, and cylinder B is located at the right side of the docking platform.

[0012] Furthermore, a rectangular slot is provided at the rear center of the top of the operating table. The rectangular slot of the operating table is located at the rear center of the top of the collection rack. A buckle is provided above the rectangular slot of the operating table. A cylinder C is fixedly installed at the top of the buckle. The cylinder C is located at the rear right side of the delivery machine.

[0013] Furthermore, an auxiliary frame is fixedly installed at the bottom rear end of the motor frame. The auxiliary frame is located behind the detection frame. A motor C is fixedly installed on the right side of the auxiliary frame. The two ends of the shaft of the motor C are provided with reverse threads. A contact plate is slidably connected to the left and right sides inside the auxiliary frame. Threaded holes are opened at the middle rear position of the sides of the two contact plates.

[0014] Furthermore, a sensor is provided on the inner side of each of the contact plates, with two sensors located on the lower sides of the middle of the detection frame.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The three sliding grooves of the testing frame, the fitting parts, and the bevel gear ring work together to precisely fit the three fitting parts onto the inner ring of the bearing. At the same time, the design of the motor C and the contact plate allows the two contact plates to limit the inner ring of the bearing, thereby achieving precise fixing and positioning of the bearing and ensuring the accuracy of the test results.

[0016] The device controls the operation of components such as the conveyor, delivery machine, cylinder A, and cylinder B through a controller, realizing the automatic conveying and detection of bearings and the automatic collection of faulty bearings. This reduces manual intervention, improves detection efficiency, and lowers labor costs.

[0017] The combination of the detection motor, bevel gear, and bevel gear ring enables the detection frame to drive the inner ring of the bearing to rotate. At the same time, the sensor can detect the jerking sensation when the bearing rotates, thereby detecting the rotation status of the inner ring of the bearing. In addition, the device can also detect the installation and operating status of the bearing, realizing comprehensive bearing detection, reducing missed and false detections, and enabling timely detection of potential bearing faults.

[0018] When the sensor detects a fault in a bearing component, the electrical control cylinder C retracts, collecting the faulty bearing component into a collection rack. For qualified bearing components, cylinder B and a delivery machine transport them to the top left position of the conveyor, thus realizing intelligent classification and collection of faulty and qualified bearings.

[0025] As attached Figure 1 To be continued Figure 9 As shown: This invention provides an intelligent induction bearing fault diagnosis device, comprising: a device frame 1; an extension frame 102 fixedly installed at the upper rear end of the device frame 1, an electrical box 3 fixedly installed at the top of the extension frame 102, a bracket 301 fixedly installed at the right front end of the electrical box 3, a detection cylinder 302 fixedly connected to the bottom front end of the bracket 301, a motor frame 303 fixedly installed at the bottom of the detection cylinder 302, a motor A304 fixedly installed inside the motor frame 303, a detection frame 305 fixedly installed on the bottom shaft of the motor A304, the detection frame 305 being located below the motor frame 303, and the detection frame 305 having a central internal structure.

[0027] Among them, a docking platform 207 is provided at the top right front end of the operating platform 2. The docking platform 207 is located directly below the detection frame 305, and the top of the docking platform 207 is flush with the top of the conveyor 201.

[0028] Among them, a delivery machine 208 is set at the top left front end of the operating table 2. The delivery machine 208 has an arc design, and the top of the delivery machine 208 is flush with the top of the docking platform 207.

[0029] Among them, cylinder A203 is installed at the front right side of the conveyor 201, and cylinder A203 is located at the front end of the docking platform 207. Cylinder B204 is installed at the right front of the operating platform 2, and cylinder B204 is located at the right side of the docking platform 207.

[0030] The operating platform 2 has a rectangular slot at the top center rear position. The rectangular slot of the operating platform 2 is located at the top rear position of the collection rack 103. A buckle 205 is set above the rectangular slot of the operating platform 2. A cylinder C206 is fixedly installed at the top position of the buckle 205. The cylinder C206 is located at the right rear position of the delivery machine 208.

[0031] An auxiliary frame 4 is fixedly installed at the bottom rear end of the motor frame 303. The auxiliary frame 4 is located behind the detection frame 305. A motor C401 is fixedly installed on the right side of the auxiliary frame 4. The two ends of the shaft of the motor C401 are provided with reverse threads. A contact plate 402 is slidably connected to the left and right sides of the inside of the auxiliary frame 4. Threaded holes are opened at the middle rear position of the sides of the two contact plates 402, and the reverse threads on both sides of the shaft of the motor C401 are located in the threaded holes of the contact plates 402 respectively.

[0032] Each contact plate 402 has a sensor 403 installed on its inner side, and the two sensors 403 are located on the lower sides of the middle of the detection frame 305.

[0033] When using: First, place the bearing component 5 on the top right side of the conveyor 201. Then, activate the controller 101 to start the conveyor 201 and delivery machine 208. The conveyor 201 moves the bearing component 5 to the left until it is in contact with the right side of the separator 202. Next, cylinder A203 extends, pushing the bearing component 5 to the top center of the docking platform 207. The bearing component 5 will then be positioned directly below the detection frame 305. Activate the detection cylinder 302. The three fitting parts 309 are inserted into the inner side of the bearing part 5 at their bottom positions. The rotating shaft of the detection motor 307 drives the bevel gear 308 to rotate. Through the meshing of the bevel gear 308 and the bevel ring 306, the bevel ring 306 rotates inside the detection frame 305. The arc-shaped wire positions of the three fitting parts 309 mesh with the bottom spiral wire of the bevel ring 306. The three fitting parts 309 slide outward in the three sliding grooves of the detection frame 305 until the three fitting parts 309 are in contact with the inner ring of the bearing part 5. At the same time, the starting motor C401 causes the shaft with reverse threads to rotate. The reverse threads of the motor C401 shaft cooperate with the threaded holes of the two contact plates 402. The two contact plates 402 slide in opposite directions inside the auxiliary frame 4 until the sensors 403 set on the two contact plates 402 respectively contact the inner ring position of the clamping bearing 5. At this time, the bearing 5 will be limited. During testing, the motor A304 is started to drive the entire testing frame 305 to rotate. The three mating parts 309 follow the center position of the testing frame 305 to rotate, pulling the inner ring of the bearing 5 to rotate. The bearing 5 is then subjected to fault diagnosis and testing. When the bearing 5 has a rotation fault, since the bearing 5 is in operation, it will generate a jamming inertia. The force will be directly transmitted to the sensor 403. The sensor 403 receives the jerking sensation and feeds the information back to the electrical box 3 to determine the fault of the bearing 5.

[0034] After the bearing component 5 is inspected, the two contact plates 402 are reset away from the position of disengaging from the outer ring of the bearing component 5, and the three bonding components 309 are reset close to the position of disengaging from the inner ring of the bearing component 5. After the bearing component 5 passes the inspection, the bearing component 5 is reset to the top middle position of the docking platform 207 without restraint. The cylinder B204 is activated to extend, and the cylinder B204 pushes the bearing component 5 from the docking platform 207 to the top right position of the delivery machine 208. The delivery machine 208 then transports the bearing component 5 to the top left position of the conveyor 201.

[0035] After bearing component 5 fails the inspection, it resets to the top center position of docking platform 207 without restraint. Cylinder B204 is then activated to extend the bearing component 5 from docking platform 207 to the top right position of delivery machine 208. Sensor 403 receives a jerking sensation and feeds the information back to electrical box 3. Electrical box 3 then controls cylinder C206 to retract. The lower part of the front end of cylinder C206 will drive bearing component 5, located on the top right side of delivery machine 208, to move backward. Bearing component 5 passes through the inside of buckle 205 and enters the rectangular slot of operating platform 2, and then falls to collection rack 103 to collect the faulty bearing component 5.

[0036] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. The scope of protection of this disclosure shall be determined by the scope of the claims.
