Description

Technical Field

[0001] This utility model relates to a vibration detection device, and more particularly to a bearing vibration detection device applied in the field of detection devices. Background Technology

[0002] In today's industrial production, bearings are crucial components of mechanical equipment, and their operating condition directly affects the overall performance and operational stability of the equipment. Accurate and efficient detection of bearing vibration is of great significance for ensuring normal equipment operation and preventing malfunctions.

[0003] Chinese patent CN215640016U discloses a bearing vibration detection device, which includes a table, a control box on the upper surface of the table, fixed plates symmetrically arranged on the upper surface of the table, a sliding plate between the two fixed plates, and a moving motor inside the table. This application has the effect of maintaining the accuracy and stability of the detection device and the rotating plate.

[0004] Chinese patent CN206601237U discloses a bearing vibration detection device. The key technical points of the device are: it includes a frame, a rotating shaft, a motor, a three-jaw chuck clamp, jaws set on the three-jaw chuck clamp, an abutment component, and a detection device set on the frame for detecting bearing vibration. The length of the jaws is increased until they can fully engage with the inner ring of the bearing. Then, the position of the movable rod is fixed by a limiting component. This makes it difficult for the movable rod to move during bearing testing. This design improves the applicability of the bearing vibration detection device to a certain extent.

[0005] In practical applications, bearings need to withstand loads from different directions and of varying magnitudes. Due to the lack of effective load simulation methods in existing testing devices, these actual stress states cannot be reproduced, resulting in the collected vibration signals failing to accurately reflect the vibration characteristics of the bearing under actual loads. Utility Model Content

[0006] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is that in practical applications, bearings need to bear loads from different directions and of constantly changing magnitudes. Since existing detection devices lack effective load simulation methods, they cannot reproduce such actual stress states, resulting in the collected vibration signals failing to truly reflect the vibration characteristics of the bearing under actual loads.

[0007] To address the aforementioned problems, this utility model provides a bearing vibration detection device, comprising a detection equipment body assembly, a clamping assembly at the front end of the detection equipment body assembly, a flexible load assembly within the detection equipment body assembly, a control terminal at the side end of the detection equipment body assembly, and a replaceable load assembly at the rear of the flexible load assembly. The detection equipment body assembly includes an equipment frame, a motor output spindle fixedly connected to the front end of the vertical front of the equipment frame, a secondary sleeve shaft mounted at the front end of the motor output spindle, and a bearing body to be tested sleeved on the outer end of the secondary sleeve shaft. A sensor is fixedly connected to the lower horizontal side of the equipment frame. The lower end of the sensor equipment compartment is equipped with a vibration probe that contacts the bearing body to be tested. The flexible load assembly includes two vertically symmetrically arranged uprights. The upper end of the vertical uprights is fixedly connected to a cylindrical support shaft. The outer end of the cylindrical support shaft is fitted with a cylinder. The rear ends of the two cylinders are fixedly connected to the iris structure body. The inner end of the iris structure body is rotatably connected to multiple flexible adaptive contact adjustment blades. The rear end of the iris structure body is equipped with multiple back frame plates that are interconnected with the buffer joint abutment. The outer end of the cylindrical support shaft has multiple annularly spaced circular grooves. The inner end of the circular grooves is fixedly connected to an electric actuator.

[0008] In the aforementioned bearing vibration testing device, the flexible load component in this solution supports the iris structure when not in operation to avoid interference with assembly. Before testing, the flexible adaptable contact-type adjusting blades automatically adjust to fit the bearing. During testing, the resistance is released to provide a stable load, accurately simulating the actual force and improving the authenticity and reliability of the test.

[0009] As a further improvement of this application, the end of the electric actuator away from the cylindrical support shaft is fixedly connected to a contact surface that contacts the inner wall of the cylinder and is provided with an arc-shaped abutment.

[0010] As a further improvement to this application, the clamping assembly includes an electrical guide rail, the output end of which is equipped with a displacement bracket.

[0011] As a further improvement of this application, a plurality of buffer joint supports are fixedly connected to one end of the displacement bracket near the motor output spindle, and the plurality of buffer joint supports are in contact with the outer circle of the bearing body to be tested.

[0012] As a further improvement to this application, the control terminal includes an electrical rack disposed on the left side of the equipment rack, and a control panel is fixedly connected to the outer end of the electrical rack.

[0013] As a further improvement to this application, the replaceable load capacity component includes a weight ring plate detachably connected to the rear end of the back frame plate, with multiple magnetic rings fixedly connected to the outer side of the weight ring plate.

[0014] As another improvement of this application, multiple magnetic rings are fixedly connected to the outer end of the back frame, and the corresponding back frame and weight ring are magnetically connected to each other through the corresponding magnetic rings and magnetic force rings.

[0015] In summary, this solution uses an electrically driven guide rail to drive a displacement bracket, allowing the buffer joint to flexibly contact the outer edge of the bearing, achieving stable fixation while preventing damage and preventing displacement from affecting the results during testing. The vibration probe maintains close contact with the bearing, and the control terminal transmits and analyzes data in real time, ensuring accurate testing. The flexible load component supports the iris structure when not in operation, avoiding interference with assembly. Before testing, the flexible adaptable contact adjustment blades automatically adjust to fit the bearing, releasing resistance during testing to provide a stable load and accurately simulating actual stress, allowing vibration testing to be conducted in an environment close to actual working conditions. The replaceable load component allows for quick replacement of the weight ring via magnetic connection, flexibly adjusting the load to meet the needs of different scenarios, improving the authenticity and reliability of testing. Overall, the operation is simple and adaptable to various bearing testing applications. Attached Figure Description

Detailed Implementation

[0025] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0026] First implementation method:

[0027] Figures 1-7 A bearing vibration detection device is shown, comprising a detection equipment body assembly 1, a clamping assembly 2 at the front end of the detection equipment body assembly 1, a flexible load assembly 3 within the detection equipment body assembly 1, a control terminal 4 at the side end of the detection equipment body assembly 1, and a replaceable load assembly 5 at the rear of the flexible load assembly 3. The detection equipment body assembly 1 includes an equipment frame 100, with a motor output spindle 101 fixedly connected to the front end of the vertical front of the equipment frame 100 (a Y132M-4 type motor spindle can be used). A secondary sleeve shaft 102 is mounted at the front end of the motor output spindle 101, and the bearing body to be tested is sleeved on the outer end of the secondary sleeve shaft 102. A sensor equipment compartment 103 is fixedly connected to the lower side of the horizontal plane of the equipment frame 100, and a vibration probe 1 that contacts the bearing body to be tested is mounted at the lower end of the sensor equipment compartment 103. 04. The 352C65 type acceleration vibration sensor, the flexible load component 3 includes two vertically uprights 305 arranged symmetrically on the left and right. The upper end of the vertical uprights 305 is fixedly connected to a cylindrical support shaft 303. The outer end of the cylindrical support shaft 303 is fitted with a cylinder 304. The rear ends of the two cylinders 304 are fixedly connected to an iris structure body 300. The inner end of the iris structure body 300 is rotatably connected to multiple flexible adaptive contact adjustment blades 302. The RF-370 type micro DC motor of Mabuchi, Japan can be selected. The rear end of the iris structure body 300 is equipped with multiple back frame pieces 301 that are interconnected with the buffer joint abutment 202. The outer end of the cylindrical support shaft 303 is provided with multiple annularly spaced circular grooves 307. The inner end of the circular grooves 307 is fixedly connected to an electric push rod 308, which can be selected as RT-05 type.

[0028] The electric actuator 308 has an arc-shaped abutment 306 fixedly connected to one end away from the cylindrical support shaft 303. The contact surface of the electric actuator 308, which contacts the inner wall of the cylinder 304, is also provided with an arc-shaped abutment 306. The clamping assembly 2 includes an electric guide rail 200, which can be a Panasonic MINASA 6 series servo motor. A displacement bracket 201 is installed at the output end of the electric guide rail 200. Multiple buffer joint abutments 202 are fixedly connected to one end of the displacement bracket 201 near the motor output spindle 101. The multiple buffer joint abutments 202 are in contact with the outer circle of the bearing body to be tested. The control terminal 4 includes an electric frame 400 located on the left side of the equipment frame 100. The outer end of the electric frame 400 is fixedly connected to... With control panel 401, Advantech's IPC-610L industrial panel PC can be used as the hardware carrier for the control terminal. It is equipped with the Windows 10 IoT Enterprise operating system. Operators can set various detection parameters on control panel 401, such as motor speed, detection duration, and data acquisition frequency. The software converts these parameters into control commands and sends them to the drive system of motor output spindle 101, the servo control system of electric guide rail 200, and the data acquisition module in sensor equipment compartment 103 through the corresponding interface. At the same time, it receives and displays the vibration signal data collected by vibration probe 104 in real time.

[0029] Figures 2-7 This solution demonstrates that the vibration detection of the bearing body under test is achieved through the collaborative operation of multiple components. The bearing body under test is sleeved on the outer end of the secondary shaft 102 of the main body component 1 of the testing equipment. The motor output shaft 101 provides rotational power. The clamping component 2 drives the displacement bracket 201 to move through the electric guide rail 200, so that the buffer joint abutment 202 contacts the outer circle of the bearing body under test, thereby achieving axial fixation of the bearing body under test and avoiding displacement during testing.

[0030] Vibration probe 104 is installed in the sensor equipment compartment 103 at the lower end of the equipment frame 100. It contacts the bearing body to be tested to collect vibration data. When the motor output spindle 101 drives the bearing body to be tested to rotate, the vibration probe 104 monitors the vibration signal in real time. The control panel 401 of the control terminal 4 receives and processes the signal to complete the display and analysis of the detection data.

[0031] The flexible load assembly 3 achieves load adaptation through an iris structure and position adjustment. Two vertical poles 305 are vertically fixed to the horizontal plane of the equipment frame 100, and the cylindrical support shaft 303 at their upper end provides sliding support for the cylinder 304. In the non-working state, the electric push rod 308 extends from the circular groove 307, driving the arc-shaped abutment 306 to tightly abut against the inner wall of the cylinder 304, supporting the iris structure body 300 to a position away from the bearing, avoiding interference with the assembly of the bearing body to be tested. When the bearing body to be tested is assembled and before testing is started, the electric push rod 308 remains extended, and multiple flexible adaptation contact adjustments within the iris structure body 300 are maintained. The blade 302 has a flexible adapting layer made of silicone on its contact surface. Driven by a built-in micro motor, it rotates and automatically adjusts the blade opening angle according to the outer diameter of the bearing body under test until the inner side of the blade is completely in contact with the outer side of the bearing body under test. When the test is started, the electric push rod 308 retracts into the circular groove 307, releasing the resistance to the cylinder 304. At this time, under its own weight and the traction of the back frame 301, the iris structure body 300 applies stable pressure to the bearing body under test through the flexible adapting contact adjustment blade 302, providing a corresponding load to the bearing body under test and accurately simulating the radial pressure that the bearing body under test is subjected to in actual equipment.

[0032] Second implementation method:

[0033] Figure 2 , Figure 5 A bearing vibration detection device is shown. The replaceable load assembly 5 includes a weight ring plate 500 detachably connected to the rear end of the back frame plate 301. Multiple magnetic rings 502 are fixedly connected to the outer side of the weight ring plate 500. Multiple magnetic rings 501 are fixedly connected to the outer end of the back frame plate 301. The corresponding back frame plate 301 and weight ring plate 500 are magnetically connected to each other through the corresponding magnetic rings 501 and magnetic rings 502.

[0034] The replaceable load assembly 5 enables rapid load adjustment via magnetic connection: multiple magnetic rings 501 at the rear end of the back frame 301 and magnetic rings 502 on the outside of the weight ring 500 are tightly attracted by the principle of opposite pole attraction. The weight rings 500 can be selected in different weight specifications according to the testing requirements, such as 500g, 1kg, and 2kg. During installation, simply align the magnetic ring 502 with the magnetic ring 501 and push gently to fix it. During disassembly, a slight pull is required to separate them. By increasing or decreasing the number of weight rings 500 or replacing them with rings of different weights, the total load applied to the bearing body under test by the flexible load assembly 3 can be flexibly adjusted to meet the vibration testing requirements of the bearing body under test in different models and working scenarios, further improving the authenticity and reliability of the test results.

[0035] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
