Technical Field
[0001] The utility model relates to the technical field of bearing detection, in particular to a bearing roller detection device. Background Art
[0002] Rollers are the components that bear the load when the bearing is running. They are the weakest parts in roller bearings. Their manufacturing quality has a great influence on the working performance of the bearing (such as rotation accuracy, vibration, noise and flexibility, etc.), and is the main factor affecting the service life of the bearing. There are many types of rollers, which are divided into tapered rollers, cylindrical rollers, spherical rollers, spiral rollers and various types of needle rollers according to their shapes and sizes. Bearing roller detection is an important part of bearing detection. The main purpose is to ensure that the quality and performance of bearing rollers meet the standard requirements. The existing detection method is to use ultrasonic detection equipment to detect whether the bearing rollers have cracks, inclusions and other defects. This method can detect the defects inside the bearing rollers, and use measuring tools such as vernier calipers and micrometers to measure the diameter, length, width and other dimensions of the bearing rollers to ensure that they meet the standard requirements. However, in order to meet the large-scale detection, the existing detection method usually needs to cooperate with the machine to detect the rollers. During the detection process, the position of the rollers usually needs to be adjusted manually, which reduces the efficiency and effect of roller detection. Utility Model Content

[0008] The beneficial effect of this improvement is that the driving motor drives the screw rod to rotate, which can drive the slider and the clamping block to slide. During the sliding process of the clamping block, the sliding groove opened on the base of the device can guide and limit the sliding of the clamping block to ensure the stability of the sliding of the clamping block.
[0009] To ensure that the top pins hold the bearing rollers:
[0010] As a further improvement of the above technical solution: a damping gasket is sleeved on the middle part of the buffer spring.
[0011] As a further improvement of the above technical solution: a sliding groove is provided at a position of the clamping block close to the ejector pin, and the ejector pin and the buffer spring are arranged with their axes coincident.
[0012] The beneficial effects of the present improvement are as follows: the damping gasket can absorb the impact on the ejector pin when the ejector pin is subjected to force, thereby providing a buffer for the ejector pin; the sliding groove can guide and limit the sliding of the ejector pin when the ejector pin contracts; and the axis overlap setting can ensure the reliability of the buffer spring in absorbing the impact of the ejector pin.

[0015] As a further improvement of the above technical solution: two support rods are symmetrically arranged about the center line of the storage tray, and a lifting and mounting structure is formed between the support rods and the storage tray through a hydraulic cylinder.
[0016] The beneficial effect of this improvement is that the symmetrically arranged hydraulic cylinders can push the support rods to rise smoothly, and the two support rods can provide comprehensive and reliable support for the bearing rollers. By driving the support rods up and down through the hydraulic cylinders, the height of the bearing rollers can be adjusted, thereby facilitating the axis of the bearing rollers to align with the ejector pin.
[0017] To facilitate the rotation of the lifting roller:
[0018] As a further improvement of the above technical solution: a bearing is installed at the connection between the lifting roller and the support rod.

[0020] To facilitate the rotation of the storage tray:
[0021] As a further improvement of the above technical solution: a bearing is installed at the connection between the storage tray and the device base.

[0030] In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the utility model.
[0031] like Figure 1-5As shown, the bearing roller detection device includes a device base 1 and a servo motor 3, an ultrasonic monitoring device 11 and a CCD camera 12 are installed above the device base 1, a driving motor 2 is installed on the outside of the device base 1, and a screw 21 is installed at the output end of the driving motor 2, a slider 22 is installed on the screw 21, and a clamping block 23 is connected above the slider 22, a buffer spring 24 is installed on the top of the clamping block 23, and a thimble 25 is connected to the buffer spring 24, the servo motor 3 is installed at the bottom of the device base 1, and a planetary gear reducer 31 is installed at the output end of the servo motor 3, a storage tray 32 is connected above the planetary gear reducer 31, and a hydraulic cylinder 4 is installed inside the storage tray 32, A support rod 41 is connected to the top of the hydraulic cylinder 4, a servo motor 42 is installed inside the support rod 41, and a synchronous belt 43 is installed at the output end of the servo motor 42, and a lifting roller 44 is connected to the top of the synchronous belt 43. The servo motor 3 drives the storage tray 32 to rotate through the planetary gear reducer 31, so that the two ends of the bearing roller point to the position of the ultrasonic monitoring device 11. In this way, there is no need to manually adjust the position of the roller, thereby ensuring the efficiency and effect of the bearing roller detection. A slide groove is provided at the position of the clamping block 23 near the base 1 of the device. The driving motor 2 drives the screw rod 21 to rotate, which can drive the slider 22 and the clamping block 23 to slide. During the sliding process of the clamping block 23, the slide groove provided on the base 1 of the device can be used to clamp the The sliding of the holding block 23 is guided and limited to ensure the stability of the sliding of the clamping block 23. The middle part of the buffer spring 24 is sleeved with a damping gasket. The clamping block 23 is provided with a slide groove near the ejector pin 25, and the ejector pin 25 and the buffer spring 24 are arranged with an axis overlap. The damping gasket can absorb the impact of the ejector pin 25 when the ejector pin 25 is subjected to force, and the ejector pin 25 is buffered. When the ejector pin 25 contracts, the sliding of the ejector pin 25 can be guided and limited by the slide groove. The axis overlap setting can make the buffer spring 24 absorb the impact of the ejector pin 25 reliably. The hydraulic cylinder 4 is symmetrically arranged about the center line of the storage tray 32. The support rod 41 is symmetrically arranged with two support rods 41 about the center line of the storage tray 32, and the support rod 41 is arranged with the storage tray 32. A lifting and mounting structure is formed between the support plates 32 through the hydraulic cylinder 4. The symmetrically arranged hydraulic cylinder 4 can push the support rod 41 to rise smoothly. The two support rods 41 can fully and reliably support the bearing rollers. The support rods 41 are driven up and down by the hydraulic cylinder 4, so that the height of the bearing rollers can be adjusted, thereby facilitating the axis of the bearing rollers to align with the ejector pin 25. A bearing is installed at the connection between the lifting roller 44 and the support rod 41, and the friction force of the lifting roller 44 when rotating can be reduced by the bearing. A bearing is installed at the connection between the storage support plate 32 and the device base 1, and the friction force of the storage support plate 32 when rotating can be reduced by the bearing, thereby facilitating the storage support plate 32 to adjust the position of the bearing roller under the drive of the servo motor 3 and the planetary gear reducer 31.
[0032] The working principle of the utility model is as follows: when using the device, the bearing roller is placed above the support rod 41, and the support rod 41 is pushed up and down by the hydraulic cylinder 4 to adjust the height of the support rod 41 and the bearing roller, so that the axis of the bearing roller is aligned with the ejector pin 25. At this time, the driving motor 2 drives the slider 22 and the clamping block 23 to move toward the support rod 41 through the screw rod 21. The ejector pin 25 is driven by the clamping block 23 to contact the bearing roller. After the contact, the ejector pin 25 is forced to squeeze the buffer spring 24 and the damping contraction, thereby increasing the pressure of the ejector pin 25 on the contact point of the bearing roller to ensure the stability of the clamping. After the clamping is completed, the servo Motor 2 42 drives the lifting roller 44 to rotate through the synchronous belt 43, and then drives the bearing roller to rotate. The CCD camera 12 performs CCD detection on the bearing roller. After the detection is completed, the drive motor 2 drives the ejector 25 to disengage from the bearing roller through the screw 21. At this time, the servo motor 1 3 drives the storage tray 32 to rotate through the planetary gear reducer 31, so that the two ends of the bearing roller point to the position of the ultrasonic monitoring device 11. At this time, the ultrasonic monitoring device 11 can perform ultrasonic detection on the bearing roller. This method does not need to manually adjust the position of the roller, thereby ensuring the efficiency and effect of the bearing roller detection.
