Description

Technical Field

[0001] The utility model relates to the technical field of roundness detection, in particular to a cylindrical roller roundness detection device. Background Art

[0002] As a key component in the mechanical field, cylindrical roller bearings are widely used in automobiles, industrial equipment, precision instruments and other fields. Their performance directly affects the operating efficiency and life of the equipment. As the core component of rolling bearings, the roundness of cylindrical rollers is an important indicator to measure their quality. The quality of roundness directly affects the stability, noise, vibration and service life of bearings during operation. In the manufacturing process of cylindrical rollers, due to the influence of various factors such as materials, processes, equipment accuracy, etc., various shape errors may exist on the roller surface, such as roundness error and cylindricity error. If these errors exceed the allowable range, the bearings will shake, get stuck, increase noise and other phenomena during operation, which will affect the performance and service life of the entire equipment. Traditional roundness detection methods often rely on manual measurement and contact measurement tools, such as micrometers and vernier calipers. These methods are not only inefficient, but also easily affected by human factors, resulting in inaccurate measurement results. In addition, for high-speed bearings, contact measurement may also cause damage to the roller surface. In summary, a cylindrical roller roundness detection device is proposed to solve the above problems. Utility Model Content

[0017] In this embodiment, the tilting platform 2 on the workbench 1 is tilted to facilitate the smooth rolling of the cylindrical roller on the tilting plate 3 under the action of gravity. The cylindrical roller is placed on the tilting plate 3 on the tilting platform 2 for easy detection and operation, and is fixed on the top of the tilting plate 3 by the roller clamping component; the first infrared ray 5 and the second infrared ray 6 on the infrared ray array do not contact the cylindrical roller for detection. The first infrared ray 5 and the second infrared ray 6 are arranged side by side, and are adjusted to be higher than the tilting plate 3 by adjusting the lifting mechanism, parallel to the tilting plate 3 and aligned with the highest point of the cylindrical roller, and are used to irradiate the roundness of the top of the cylindrical roller. By observing whether the area on the baffle plate 15 that blocks the infrared rays at the highest point of the cylindrical roller changes, the roundness of the top of the roller is judged; the third infrared ray 7 is set at the tail of the tilting plate 3, aligned with and parallel to the bottom area of the cylindrical roller. This beam of ray is used to irradiate the roundness of the bottom of the roller, revealing a red light, judging the radial jump of the cylindrical roller on the tilting plate 3, and judging the roundness of the cylindrical roller. The guide track 4 is set on the tilting plate 3 to provide a rolling path for the cylindrical roller.

[0018] like Figure 2As shown in the figure, further, the lifting mechanism includes a lifting platform 8, support columns 9, and a mounting plate 10. The support columns 9 are arranged on the working frame 1, the lifting platform 8 is sleeved on the support columns 9, and the lifting platform 8 vertically ascends and descends on the support columns 9. The mounting plate 10 is arranged on the top of the lifting platform 8. In this embodiment, the support columns 9 are the tracks for the vertical movement of the lifting platform 8. The lifting platform 8 can vertically ascend and descend along the support columns 9, and the lifting is achieved through conventional mechanical transmission in the art. The infrared rays on the mounting plate 10 at the top are aligned with the cylindrical rollers, and the infrared ray array on the mounting plate 10 maintains a certain distance from the cylindrical rollers. According to the actual size and position of the cylindrical rollers, the vertical lifting of the lifting platform 8 is controlled. The first infrared ray 5 and the second infrared ray 6 are aligned with the highest points of the cylindrical rollers, and cylindrical rollers with different diameters can be detected.

[0019] As Figure 3 shown in the figure, further, the roller clamping component includes a cylinder 11, a push rod 12, a positioning block 13, and a pressing plate 14. The cylinder 11 and the positioning block 13 are horizontally arranged at intervals on the top of the inclined plate 3. One end of the cylinder 11 is connected to the pressing plate 14 through two push rods 12. In this embodiment, the cylinder 11 is horizontally arranged on the top of the inclined plate 3, at a certain distance from the positioning block 13, so as to provide enough clamping space for the rollers. When it is necessary to clamp the rollers, the piston of the cylinder 11 pushes forward, and the pressing plate 14 is pushed towards the rollers through the push rod 12. The pressing plate 14 can tightly press on the rollers. The positioning block 13 is arranged on the top of the inclined plate 3, at a certain distance from the cylinder 11, to provide a limit for clamping the rollers. When the cylinder 11 receives the release signal, the piston pulls the push rod 12 backward, driving the pressing plate 14 to leave the surface of the rollers, and the rollers are released and start to roll.

[0020] As Figure 1 shown in the figure, further, a baffle plate 15 is arranged at the end of the inclined plate 3. The baffle plate 15 is vertically fixed to the inclined plate 3. The baffle plate 15 prevents the cylindrical rollers from slipping or deviating at the end of the inclined plate 3, and the irradiation areas of the first infrared ray 5 and the second infrared ray 6 can be observed and displayed on the surface of the baffle plate 15.

[0021] As Figure 1 shown in the figure, further, limit blocks 16 are arranged on both sides of the guide rail 4. The limit blocks 16 limit the lateral movement of the cylindrical rollers, ensure their stable rolling in the guide rail 4, and prevent the cylindrical rollers from deviating from the predetermined path during the rolling process.

[0022] As Figure 1 shown in the figure, on the basis of the above method, further, a vibration isolation pad 17 is arranged at the connection between the inclined platform 2 and the inclined plate 3. The vibration isolation pad 17 reduces the vibration between the inclined platform 2 and the inclined plate 3, and ensures the smooth rolling of the cylindrical rollers on the inclined plate 3.

[0023] In the specific working process of the new cylindrical roller roundness detection device, the cylindrical roller to be detected is placed on the inclined plate 3 and fixed by the roller clamping component. The cylinder 11 of the roller clamping component pushes the push rod 12 to press the pressing plate 14 against the roller. The lifting mechanism is adjusted to align the first infrared ray 5 and the second infrared ray 6 with the highest point of the cylindrical roller, and the third infrared ray 7 is aligned with the bottom area of the cylindrical roller; the roller clamping component is released, and the cylindrical roller rolls on the inclined plate 3 along the guiding track 4 under the action of gravity. During the rolling process, the first infrared ray 5 and the second infrared ray 6 irradiate the top of the cylindrical roller, and the roundness of the roller top is judged by observing the change of the infrared ray irradiation area on the baffle plate 15. At the same time, the third infrared ray 7 irradiates the bottom of the cylindrical roller, and the radial runout and roundness of the cylindrical roller are judged by observing the exposure of the red light. The roundness of the cylindrical roller is evaluated based on the observation of the infrared ray array.
