Description

Technical Field

[0001] This utility model relates to the field of single-bar bearing technology, specifically a detection device for detecting cracks in single-bar bearings. Background Technology

[0002] Single-bar bearings are indispensable key components in mechanical equipment and are widely used in many fields such as automotive manufacturing, aerospace, and industrial automation. In these applications, the quality and reliability of single-bar bearings are directly related to the operational safety and performance of the entire equipment.

[0003] In practical use, single-bar bearings are subjected to complex loads and stresses, and are prone to defects such as cracks after long-term operation. These cracks may gradually propagate over time, eventually leading to bearing failure, equipment malfunction, or even serious safety accidents. Therefore, timely and accurate detection of cracks in single-bar bearings is crucial.

[0004] Currently, common methods for detecting cracks in single-bar bearings mainly include manual inspection and single-instrument inspection. Manual inspection relies primarily on the experience and visual observation of the inspectors, using methods such as tapping and touching to determine the presence of cracks in the bearing. This method is inefficient, and the accuracy and reliability of the test results largely depend on the skill level and working condition of the inspectors, making it prone to missed detections and misjudgments. Moreover, manual inspection is almost unable to detect some micro-cracks or internal cracks. Utility Model Content

[0007] The clamping and rotating mechanism includes a fixed frame, which is fixedly connected to the top of the base. A first rotating shaft is arranged on the left side of the fixed frame near the top. A first rubber clamping plate is fixedly connected to the right end of the first rotating shaft. An L-shaped seat is fixedly connected to the left side of the fixed frame near the bottom. A first servo motor is fixedly connected to the left side of the L-shaped seat. A first pulley is fixedly connected to the surface of the output shaft of the first servo motor. A second pulley is fixedly connected to the surface of the first rotating shaft near the left end. A belt is sleeved between the first pulley and the second pulley. A cylinder is fixedly connected to the right side of the fixed frame. A moving plate is fixedly connected to the output end of the cylinder. A second rotating shaft is rotatably connected to the left side of the moving plate near the top. A second rubber clamping plate is fixedly connected to the left end of the second rotating shaft. A guide rod is fixedly connected to the right side of the moving plate.

[0008] Preferably, the left side of the fixing frame near the top has a hole that matches the first rotating shaft, and the surface of the first rotating shaft passes through and is rotatably connected to the hole.

[0009] Preferably, the right side of the fixing frame has a hole that matches the cylinder output shaft, and the cylinder output shaft surface passes through and slides left and right within the hole.

[0010] Preferably, the right side of the fixing frame near the top has a hole that matches the guide rod, and the guide rod is slidably connected to the hole from the surface through it. The guide rod supports the moving plate, making the second rotating shaft and the second rubber pressing plate more stable when rotating.

[0011] Preferably, the detection mechanism includes a rectangular frame, which is fixedly connected to the left and right sides of the fixed frame. A sliding sleeve is slidably connected to the surface of the rectangular frame, and a movable frame is fixedly connected to the surface of the sliding sleeve. The front and rear sides of the movable frame are rotatably connected to a third rotating shaft. A gear is fixedly connected to the middle of the surface of the third rotating shaft. A second servo motor is fixedly connected to the front of the movable frame. A rack is fixedly connected to the left and right sides of the rectangular frame. A fixed plate is fixedly connected to the top of the sliding sleeve. A CCD camera is fixedly connected to the top left side of the fixed plate, and an ultrasonic sensor is fixedly connected to the top right side of the fixed plate.

[0012] Preferably, the front of the movable frame has a hole that matches the output shaft of the second servo motor, and the output shaft of the second servo motor passes through and is rotatably connected in the hole, and the output end of the second servo motor is fixedly connected to the front end of the third rotating shaft.

[0013] Preferably, the output end of the second servo motor is fixedly connected to the front end of the third rotating shaft, and the gear meshes with the rack.

[0014] Compared with the prior art, this utility model provides a detection device for crack detection in single-bar bearings, which has the following beneficial effects:

[0015] 1. This single-rod bearing crack detection device, through the inclusion of a clamping and rotating mechanism, utilizes a cylinder-driven moving plate to allow the second rubber clamping plate to move flexibly. In conjunction with the first rubber clamping plate, it can easily clamp and fix single-rod bearings of different sizes. This adjustable clamping method greatly improves the device's applicability to single-rod bearings of different specifications. Operators only need to control the cylinder to quickly complete the bearing clamping work, making operation simple and convenient. A first servo motor drives the first rotating shaft and the first rubber clamping plate to rotate via belt drive, thereby rotating the clamped single-rod bearing. This rotation function facilitates subsequent comprehensive testing, enabling the detection mechanism to inspect various parts of the bearing without frequent manual adjustments to the bearing position, thus improving detection efficiency.

[0016] 2. This single-bar bearing crack detection device combines a CCD camera and an ultrasonic sensor. The CCD camera, with its high resolution and excellent imaging capabilities, can clearly capture images of the single-bar bearing surface, effectively detecting surface defects such as cracks and scratches, and presenting the detection results in a clear image format. The ultrasonic sensor, on the other hand, can penetrate deep into the bearing to detect cracks, compensating for the limitation of the CCD camera in detecting only surface defects. The two work together to achieve comprehensive inspection of the single-bar bearing from the surface to the interior, greatly improving the accuracy of crack detection. Attached Figure Description

[0030] The right side of the mounting bracket 31 has a hole that matches the output shaft of the cylinder 39, and the surface of the output shaft of the cylinder 39 is penetrated and slidably connected to the hole.

[0031] The right side of the fixed frame 31 near the top has a hole that matches the guide rod 314. The guide rod 314 passes through the surface and slides left and right in the hole. The guide rod 314 supports the moving plate 311, making the second rotating shaft 312 and the second rubber pressing plate 313 more stable when rotating. Example 2

[0032] Please see Figure 4-5 Furthermore, based on Example 1, testing agency 4 was obtained.

[0033] The testing mechanism 4 includes a rectangular frame 41, which is fixedly connected to the left and right sides of the fixed frame 31. A sliding sleeve 42 is slidably connected to the surface of the rectangular frame 41. A movable frame 43 is fixedly connected to the surface of the sliding sleeve 42. The front and rear sides of the movable frame 43 are rotatably connected to a third rotating shaft 44. A gear 45 is fixedly connected to the middle of the surface of the third rotating shaft 44. A second servo motor 46 is fixedly connected to the front of the movable frame 43. A rack 47 is fixedly connected to the left and right sides of the rectangular frame 41. A fixed plate 48 is fixedly connected to the top of the sliding sleeve 42. A CCD camera 49 is fixedly connected to the top left side of the fixed plate 48. An ultrasonic sensor 411 is fixedly connected to the top right side of the fixed plate 48. A display 412 is fixedly connected to the top right side of the base 1 near the front.

[0034] The movable frame 43 has a hole on its front that matches the output shaft of the second servo motor 46, and the output shaft of the second servo motor 46 passes through and is rotatably connected in the hole. The output end of the second servo motor 46 is fixedly connected to the front end of the third rotating shaft 44.

[0035] The output end of the second servo motor 46 is fixedly connected to the front end of the third rotating shaft 44, and the gear 45 meshes with the rack 47.

[0036] In actual operation, when this device is used, firstly, the single-rod bearing to be tested is placed between the first rubber clamping plate 33 and the second rubber clamping plate 313. The cylinder 39 is activated, and its output shaft pushes the moving plate 311 to the left. Since the second rubber clamping plate 313 is fixedly connected to the second rotating shaft 312 on the left side of the moving plate 311, the second rubber clamping plate 313 will move to the left along with the moving plate 311 until it clamps the single-rod bearing together with the first rubber clamping plate 33. During this process, the guide rod 314 slides left and right in the hole near the top on the right side of the fixed frame 31, supporting the moving plate 311 and ensuring the stability of the movement of the second rotating shaft 312 and the second rubber clamping plate 313, thus stably clamping the single-rod bearing. The first servo motor 35 is then activated, and its output shaft drives the first pulley 36 to rotate. Since the first pulley 36 and the second pulley 37 are connected by a belt 38, the rotation of the first pulley 36 is transmitted to the second pulley 37 through the belt 38, thereby driving the first shaft 32 to rotate. The right end of the first shaft 32 is fixedly connected to the first rubber clamping plate 33, which is in close contact with the single rod bearing. Therefore, the rotation of the first rubber clamping plate 33 will drive the clamped single rod bearing to rotate.

[0037] While the single-bar bearing rotates, the second servo motor 46 is activated, and the output shaft of the second servo motor 46 drives the third rotating shaft 44 to rotate. A gear 45 is fixedly connected to the middle of the surface of the third rotating shaft 44, and the gear 45 meshes with the racks 47 fixedly connected to the left and right sides of the rectangular frame 41. Therefore, the rotation of the third rotating shaft 44 will cause the gear 45 to roll along the racks 47, thereby driving the moving frame 43 to move left and right. The moving frame 43 is slidably connected to the surface of the rectangular frame 41 through a sliding sleeve 42. A fixed plate 48 is fixedly connected to the top of the sliding sleeve 42, and a CCD camera is fixedly connected to the top left side of the fixed plate 48. Therefore, the CCD camera will move left and right with the moving frame 43. During the movement, the CCD camera takes pictures of the rotating single-bar bearing surface and captures the surface image information. Similarly, as the moving frame 43 moves left and right, the ultrasonic sensor 411 fixedly connected to the top right side of the fixed plate 48 will also move synchronously. An ultrasonic sensor 411 emits ultrasonic waves into the single-bar bearing and receives the reflected ultrasonic signals. Changes in the signal are used to detect the presence of cracks inside the single-bar bearing. Image information captured by a CCD camera and signal data detected by the ultrasonic sensor 411 are transmitted to a display 412 fixedly connected to the top of the base 1 near the right side of the front panel. Operators can visually view the surface condition and internal structure of the single-bar bearing through the display 412, determining the presence, location, and approximate nature of cracks, thus completing the crack detection work for the single-bar bearing.
