Description

Technical Field

[0001] The present invention relates to the technical field of roller bearing detection, and in particular to a calibration test device for centering detection of cylindrical roller bearings. Background Art

[0002] Cylindrical roller bearing alignment testing refers to the process of precise axial and radial position calibration and deviation measurement of cylindrical roller bearings installed on mechanical shafting. This test is intended to ensure that the relative positional relationship between the bearing and mating components such as the shaft and bearing seat meets the design requirements, avoiding problems such as bearing deflection and misalignment caused by improper installation. By using specialized tools such as laser alignment instruments and micrometers, the bearing is tested for excessive radial and axial displacement or angular deviation, promptly identifying potential risks that may lead to premature wear, heating, increased vibration, or even failure of the bearing. Accurate alignment not only extends the service life of the bearing and reduces energy consumption, but also ensures the stable operation and efficiency of the entire mechanical system. It is a key quality control link in equipment maintenance and installation.

[0003] In traditional cylindrical roller bearing alignment testing, high-precision testing equipment such as laser alignment instruments are often used to ensure the stable operation of bearings and supporting equipment. However, this testing method has significant limitations in practical applications: on the one hand, the high purchase cost of high-precision alignment instruments and other equipment increases the company's initial investment and maintenance pressure; on the other hand, after the test is completed, manual sorting of qualified and unqualified products is often still required. This not only leads to low sorting efficiency and makes it difficult to meet the needs of large-scale production, but also manual operations are easily affected by subjective factors, making it difficult to ensure classification accuracy, which overall affects production efficiency and product quality control. Summary of the Invention

On the one hand, the purchase cost of equipment such as high-precision alignment instruments is high, which increases the initial investment and maintenance pressure of the enterprise; on the other hand, after the detection is completed, it is often still necessary to rely on manual labor to classify qualified and unqualified products, which not only leads to low sorting efficiency and makes it difficult to meet the needs of large-scale production, but also manual operation is easily affected by subjective factors, making it difficult to ensure the accuracy of classification, which overall affects the production efficiency and product quality control level.

[0019] The beneficial effects of the present invention are:

[0020] The present invention provides a detection mechanism. When performing centering detection on the cylindrical roller bearing, the cylindrical roller bearing is clamped and fixed by the inner support fixing mechanism. The other end of the cylindrical roller bearing is clamped on the inner side of the outer clamping block. The other end of the cylindrical roller bearing is clamped by the three groups of outer clamping blocks synchronously squeezing toward the middle to clamp the other end of the cylindrical roller bearing. At the same time, the pressure sensor senses the squeezing force exerted on the three groups of outer clamping blocks in real time. During detection, the inner support fixing mechanism is driven to rotate by the driving motor, thereby driving the cylindrical roller bearing to rotate, so that the cylindrical roller bearing rotates on the inner side of the outer clamping block. When the specifications of the cylindrical roller bearing are qualified, the pressure exerted on the three groups of pressure sensors is relatively uniform. When the cylindrical roller bearing product is unqualified, the pressure exerted on the three groups of pressure sensors is uneven, thereby realizing low-cost and high-efficiency detection of the centering accuracy of the cylindrical roller bearing. The pressure of qualified products is uniform, and the pressure of unqualified products is uneven, which is convenient for rapid judgment.

[0021] The present invention provides a discharging mechanism. When discharging is needed after the detection is completed, the inner support fixing mechanism first loosens the inner support clamping of the cylindrical roller bearing. Then, the first electric push rod is extended and the cylindrical roller bearing is pushed toward the middle by the push block fixedly installed at the telescopic end of the first electric push rod. At the same time, the third electric push rod is shortened to make the entire detection mechanism slide toward the outside. During the sliding process, the inner side of the outer clamping block slides into the conical stopper, and the outer clamping block is pushed outward by the conical stopper, thereby loosening the clamping of the cylindrical roller bearing. At the same time, the blocking of the conical stopper causes the cylindrical roller bearing to slowly fall out from the inner side of the outer clamping block, thereby achieving the purpose of automatic discharging. At the same time, when the detection mechanism detects that the cylindrical roller bearing is unqualified, When the cylindrical roller bearing is detected as qualified, the squeezing rod will not squeeze the discharge guide plate. At the same time, when the cylindrical roller bearing falls to the surface of the discharge guide plate, the discharge guide plate will be lifted and tilted toward the other side through the extension of the second electric push rod, so that the cylindrical roller bearing is discharged toward the other side, thereby realizing the purpose of automatic material separation, automatically releasing the bearing and realizing material separation, thereby improving sorting efficiency.

[0022] The present invention provides a buffer mechanism. When the cylindrical roller bearing falls onto the surface of the discharge guide plate after being discharged, the upper surface of the discharge guide plate is subjected to pressure, which is transmitted to the lower acting block through the inclined surface between the upper acting block and the lower acting block. The lower acting block presses the second elastic component inwardly through the force of the inclined surface. The return elastic force of the second elastic component cushions the falling cylindrical roller bearing, thereby protecting the cylindrical roller bearing from collision damage and keeping the product intact.

[0023] The present invention provides an internal support fixing mechanism. When fixing one end of the cylindrical roller bearing, the hydraulic cylinder is first shortened, and the internal support block is pulled inward through the transmission rod. Then the cylindrical roller bearing is sleeved on the outside of the internal support block. Then the hydraulic cylinder slowly extends and the internal support block is pushed outward through the transmission rod. The three groups of internal support blocks are pushed outward synchronously, thereby realizing internal support clamping and fixing of the cylindrical roller bearing, and ensuring that the center of the cylindrical roller bearing is always in the same position during each detection, thereby ensuring the accuracy and reliability of the detection.

Then the hydraulic cylinder 203 slowly extends and the inner support block 205 is pushed outward through the transmission rod 204. The three groups of inner support blocks 205 are pushed outward synchronously, thereby realizing the internal support clamping and fixing of the cylindrical roller bearing, and ensuring that the center of the cylindrical roller bearing is always in the same position during each detection, thereby ensuring the accuracy and reliability of the detection.

[0038] Example 2:

[0039] The detection mechanism 3 includes a pressure sensor 309 and an outer clamping block 311. The other side of the upper surface of the detection platform 1 is movably connected to the slider 302, the upper surface of the slider 302 is movably connected to the sliding block 306, the upper surface of the sliding block 306 is fixedly connected to the fixed disk 307, and one side surface of the fixed disk 307 is fixedly connected to the pressure sensor 309 through the connecting rod 308. The outer clamping block 311 is movably connected to the inner side of the pressure sensor 309 through the first elastic component 310; the pressure sensor 309, the first elastic component 310 and the outer clamping block 311 are all There are three groups of pressure sensors 309, which are used to determine whether the cylindrical roller bearing products are qualified.

A slide rail 301 is fixedly connected to one side of the upper surface of the inspection platform 1, and the slider 302 is slidably connected to the surface of the slide rail 301. The upper end of the slide rail 301 is fixedly connected to the upper surface of the slide rail 301.

When the specifications of the cylindrical roller bearing are qualified, the pressure on the three groups of pressure sensors 309 is relatively uniform. When the cylindrical roller bearing product is unqualified, the pressure on the three groups of pressure sensors 309 is uneven, thereby realizing low-cost and efficient detection of the centering accuracy of the cylindrical roller bearing. The qualified product has uniform pressure, and the unqualified product has uneven pressure, which is convenient for quick judgment.

[0040] Example 3:

[0041] The discharging mechanism 4 includes an extrusion rod 408 and a discharging guide plate 407. The discharging guide plate 407 is movably mounted on the upper surface of the detection platform 1 through a connecting structure 406. The extrusion rod 408 is fixedly connected to the lower part of the surface of one side of the fixed disk 307. The inner surface of the fixed plate 201 is fixedly connected to the first electric push rod 404. The telescopic end of the first electric push rod 404 is fixedly connected to the push block. One side of the upper surface of the detection platform 1 is fixedly connected to a fixed frame 401. The upper part of one side of the fixed frame 401 is fixedly connected to a conical stopper 403 through a fixed rod 402. The fixed rod 402 passes through the fixed disk 307. The fixed disk 307 is slidably connected to the surface of the fixed rod 402. The middle part of the upper surface of the detection platform 1 is fixedly connected to a fixed base 405. The discharging guide plate 407 is movably mounted on the upper part of the fixed base 405 through the connecting structure 406. A sliding groove 410 is provided on one side of the lower surface of the discharge guide plate 407. The interior of the sliding groove 410 is fixedly connected with a sliding rod 411. The surface of the sliding rod 411 is slidably connected with an upper rotating structure 412. The upper surface of the detection platform 1 is fixedly connected with a lower rotating structure 409. A second electric push rod 413 is installed between the upper rotating structure 412 and the lower rotating structure 409. The fixed end of the second electric push rod 413 is rotatably connected to the inner side of the lower rotating structure 409. The telescopic end of the second electric push rod 413 is rotatably connected to the inner side of the upper rotating structure 412. Through the set discharge mechanism 4, when the detection is completed and the material needs to be discharged, the inner support fixing mechanism 2 is first relaxed to the circular The cylindrical roller bearing is internally clamped, and then the first electric push rod 404 is extended, and the push block fixedly installed at the telescopic end of the first electric push rod 404 pushes the cylindrical roller bearing toward the middle, and at the same time the third electric push rod 312 is shortened, so that the entire detection mechanism 3 slides toward the outside. During the sliding process, the inner side of the outer clamping block 311 slides into the tapered stopper 403, and the outer clamping block 311 is pushed outward by the tapered stopper 403, thereby loosening the clamping of the cylindrical roller bearing. At the same time, the obstruction of the tapered stopper 403 causes the cylindrical roller bearing to slowly fall out from the inner side of the outer clamping block 311, realizing the purpose of automatic discharging. At the same time, when the detection mechanism 3 detects that the cylindrical roller bearing is an unqualified product, the entire detection mechanism 3 is subjected to a relatively uneven force, and the detection mechanism 3 is subjected to a relatively uneven force. The measuring mechanism 3 transmits the force to the upper surface of the discharge guide plate 407 through the squeezing rod 408, and squeezes the discharge guide plate 407 toward one side through the squeezing rod 408, so that the discharge guide plate 407 is tilted toward one side. When the cylindrical roller bearing falls to the surface of the discharge guide plate 407, it will fall out to one side. When the cylindrical roller bearing is detected to be qualified, the squeezing rod 408 will not squeeze the discharge guide plate 407. At the same time, when the cylindrical roller bearing falls to the surface of the discharge guide plate 407, the discharge guide plate 407 is lifted and tilted toward the other side through the extension of the second electric push rod 413, so that the cylindrical roller bearing is discharged toward the other side, thereby achieving the purpose of automatic material separation, automatically releasing the bearings and realizing material separation, and improving sorting efficiency.

[0042] Example 4:

[0043] A buffer mechanism 5 is installed between the fixed base 405 and the connecting structure 406. The buffer mechanism 5 includes a lower action block 502 and an upper action block 501. The upper action block 501 is fixedly connected to both sides of the lower surface of the connecting structure 406. The upper surface of the fixed base 405 is fixedly connected to a telescopic rod 503. The telescopic end of the telescopic rod 503 is fixedly connected to the lower surface of the connecting structure 406. The lower action block 502 is movably installed on both sides of the telescopic rod 503 through a second elastic component 504. The contact surface between the lower action block 502 and the upper action block 501 is an inclined surface. Through the provided buffer mechanism 5, when the cylindrical roller bearing falls to the surface of the discharge guide plate 407 after being discharged, the upper surface of the discharge guide plate 407 is subjected to pressure, and the pressure will be transmitted to the lower action block 502 through the inclined surface between the upper action block 501 and the lower action block 502. The lower action block 502 squeezes the second elastic component 504 inwardly through the action force of the inclined surface, and the return elastic force of the second elastic component 504 is used to buffer the falling of the cylindrical roller bearing, thereby playing a protective role for the cylindrical roller bearing, preventing collision damage, and keeping the product intact.

[0044] When in use, first, the cylindrical roller bearing is placed on the inner support fixing mechanism 2 for initial fixation, the hydraulic cylinder 203 is shortened, and the inner support block 205 is pulled inward by the transmission rod 204 to create space for the bearing to be sleeved into the inner support block 205, and then the cylindrical roller bearing is sleeved on the outside of the inner support block 205, and then the hydraulic cylinder 203 is slowly extended, and the three groups of inner support blocks 205 are synchronously pushed outward by the transmission rod 204, so as to realize the inner support clamping and fixing of the cylindrical roller bearing. The anti-skid grooves 206 on the outer side of the inner support block 205 and the outer side surface of the clamped end increase the friction force to ensure firm fixation and ensure that the center of the cylindrical roller bearing is always in the same position during each test, laying the foundation for the accuracy and reliability of subsequent tests. After the determination is completed, the detection mechanism 3 slides toward the middle and slowly loses the inner support of the tapered stopper 403. The three groups of outer clamping blocks 311 slowly clamp toward the middle, applying a slight clamping force to the cylindrical roller bearing in the middle. The drive motor 202 is started to drive the inner support fixing mechanism 2 and the cylindrical roller bearing thereon to rotate. The other end of the cylindrical roller bearing is placed on the inner side of the outer clamping block 311 of the detection mechanism 3. At the same time, the pressure sensor 309 senses the squeezing force exerted on the three groups of outer clamping blocks 311 in real time. During the process of the bearing being driven to rotate by the drive motor 202, the pressure sensor 309 continuously monitors. When the specifications of the cylindrical roller bearing are qualified, the outer circumference thereof is consistent, and the pressure exerted on the three groups of pressure sensors 309 during rotation will be relatively uniform.When the cylindrical roller bearing product is unqualified, there is a deviation in its outer circumference. When rotating, the pressure on the three groups of pressure sensors 309 will be uneven. By analyzing the data of the pressure sensors 309, it can be judged whether the bearing is qualified, thereby realizing low-cost and high-efficiency detection of the centering accuracy of the cylindrical roller bearing. When the detection is completed and the material needs to be discharged, the inner support fixing mechanism 2 relaxes the inner support clamping of the cylindrical roller bearing. Subsequently, the first electric push rod 404 is extended, and the push block fixedly installed at its telescopic end pushes the cylindrical roller bearing toward the middle. At the same time, the third electric push rod 312 is shortened, causing the entire detection mechanism 3 to slide toward the outside. During the sliding process, the inner side of the outer clamping block 311 slides into the conical stopper 403, and the conical stopper 403 pushes the outer clamping block 311 outward, thereby relaxing the clamping on the outer end. The obstruction of the conical stopper 403 also causes the cylindrical roller bearing to slowly fall out from the inner side of the outer clamping block 311, realizing automatic discharge. If it is detected as an unqualified product, the inspection The uneven force applied to the measuring mechanism 3 is transmitted to the upper surface of the discharge guide plate 407 through the squeezing rod 408. The squeezing rod 408 squeezes and tilts the discharge guide plate 407 toward one side, causing the bearing to fall toward that side when it falls. If the test is qualified, the squeezing rod 408 does not squeeze the guide plate. When the bearing falls onto the surface of the discharge guide plate 407, the second electric push rod 413 extends, lifting and tilting the discharge guide plate 407 toward the other side, causing the bearing to be discharged toward the other side, thus achieving automatic material separation. Finally, the cylindrical roller bearing falls onto the surface of the discharge guide plate 407. The upper surface of the guide plate is subjected to pressure, which is transmitted to the lower acting block 502 through the inclined surface between the upper acting block 501 and the lower acting block 502. Under the force of the inclined surface, the lower acting block 502 squeezes the second elastic component 504 inward. The restoring elastic force of the second elastic component 504 produces a buffering effect, thereby cushioning the impact of the cylindrical roller bearing when it falls, preventing collision damage and protecting the product intact.
