Description

Technical Field

[0001] This application relates to the technical field of bearing flaw detectors, and in particular to a bearing flaw detector. Background Technology

[0002] In the bearing manufacturing process, bearing flaw detectors are key equipment for ensuring bearing quality, mainly used to detect defects such as cracks and inclusions inside and on the surface of bearings. However, traditional bearing flaw detectors have many inconveniences in the loading and unloading process, which significantly impacts production efficiency and ease of operation.

[0003] From a structural design perspective, traditional bearing flaw detectors typically employ enclosed or semi-enclosed protective structures at their inspection stations. While this provides a degree of safety during the inspection process, it imposes spatial limitations on loading and unloading operations. The entrance to the inspection area is narrow and often too close to the core inspection components of the machine. When placing or removing bearings, operators must extend their arms into this confined space, resulting in awkward postures and a risk of collisions with internal components, posing a safety hazard.

[0004] In terms of operation, traditional bearing flaw detectors rely heavily on manual loading and unloading, lacking effective positioning and auxiliary devices. Operators must precisely align the bearing to be inspected with the center of the inspection station; even slight deviations can affect the accuracy of the inspection results, placing high demands on the operator's skill. After inspection, the bearing may experience suction or jamming due to the positioning device used during the inspection process, requiring extra effort to remove it, sometimes even necessitating tools, further increasing the complexity of the operation. Those skilled in the art have provided a bearing flaw detector to address the problems mentioned in the background. Utility Model Content

[0005] To address the problems mentioned in the background art, this application provides a bearing flaw detector.

[0006] The bearing flaw detector provided in this application adopts the following technical solution:

[0007] A bearing flaw detector includes a feeding sloping plate. Guide plates are fixedly installed on both sides of the feeding sloping plate. An electric telescopic rod is fixedly installed through one side of the guide plate. A connecting plate is fixedly installed on one side of the electric telescopic rod. A rotating motor is fixedly installed on the outside of both the connecting plate and the guide plate. A rotating roller is fixedly installed at one end of the output shaft of the rotating motor.

[0008] Preferably, a gantry frame is fixedly installed on the top of the guide plate, and a flaw detector is fixedly installed on the lower end of the gantry frame.

[0009] Preferably, a feeding sloping plate is fixedly installed at the lower end of the guide plate, and a sponge pad is fixedly installed at the upper end of the feeding sloping plate.

[0010] Preferably, two limiting plates are fixedly installed at the upper end of the feeding inclined plate, and a guide post is fixedly installed at the upper end of the limiting plate near one side.

[0011] Preferably, a top plate is fixedly installed at the upper end of the two guide pillars, and a telescopic cylinder is fixedly installed through the upper end of the top plate.

[0012] Preferably, a pressure column is fixedly installed at the lower end of the telescopic cylinder, and an infrared sensor is fixedly installed at the lower end of the top plate.

[0013] In summary, this application includes the following beneficial technical effects: In the feeding stage, the bearing to be inspected is placed on the feeding ramp, and two limiting plates can limit the bearing, preventing it from shifting during the downward movement. The bearing slides down the feeding ramp under its own weight. When it slides between the guide plates, an infrared sensor installed on the top plate at the upper end of the guide post will detect the arrival of the bearing. Subsequently, the telescopic cylinder is activated, and the pressure column at its lower end extends downward, which can assist in adjusting the position of the bearing and ensure that the bearing accurately enters the conveying channel between the guide plates. At the same time, the electric telescopic rod on one side of the guide plate will extend and retract according to the bearing specifications, and the distance is adjusted by the connecting plate to drive the rotating roller to accommodate bearings of different sizes. Then, the rotating motor is started, driving the rotating roller to rotate, and the bearing is smoothly conveyed to the flaw detection area by friction, eliminating the need for manual handling and precise alignment, greatly reducing the difficulty of operation.

[0020] The illustrative embodiments and descriptions of the present invention are provided herein to explain the invention, but are not intended to limit the invention.

[0022] It should be understood that the terms "comprising / including," "consisting of," or any other variations are intended to cover non-exclusive inclusion, such that a product, apparatus, process, or method that comprises a list of elements includes not only those elements but may also include, where necessary, other elements not expressly listed, or elements inherent to such a product, apparatus, process, or method. Without further limitation, an element defined by the phrases "comprising / including," "consisting of," does not exclude the presence of additional identical elements in the product, apparatus, process, or method that includes said element.

[0023] It should also be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device, component or structure referred to must have a specific orientation, be constructed or operated in a specific orientation, and should not be construed as a limitation of the present invention.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] like Figures 1-4As shown, a bearing flaw detector includes a feeding inclined plate 1. Guide plates 3 are fixedly installed on both sides of the feeding inclined plate 1. An electric telescopic rod 4 is fixedly installed through one side of the guide plate 3. A connecting plate 5 is fixedly installed on one side of the electric telescopic rod 4. A rotating motor 6 is fixedly installed on the outside of both the connecting plate 5 and the guide plate 3. A rotating roller 7 is fixedly installed at one end of the output shaft of the rotating motor 6.

[0026] In this embodiment, a gantry 8 is fixedly installed on the top of the guide plate 3, and a flaw detector 9 is fixedly installed on the lower end of the gantry 8.

[0027] In this embodiment, a feeding sloping plate 15 is fixedly installed at the lower end of the guide plate 3, and a sponge pad 16 is fixedly installed at the upper end of the feeding sloping plate 15.

[0028] In this embodiment, two limiting plates 2 are fixedly installed on the upper end of the feeding inclined plate 1, and a guide post 10 is fixedly installed on one side of the upper end of the limiting plate 2.

[0029] In this embodiment, a top plate 11 is fixedly installed on the upper end of the two guide posts 10, and a telescopic cylinder 12 is fixedly installed through the upper end of the top plate 11.

[0030] In this embodiment, a pressure column 13 is fixedly installed at the lower end of the telescopic cylinder 12, and an infrared sensor 14 is fixedly installed at the lower end of the top plate 11.

[0031] The implementation principle of a bearing flaw detector according to an embodiment of this application is as follows: In the feeding stage, the bearing to be tested is placed on the feeding ramp 1. Two limiting plates 2 can limit the bearing and prevent it from shifting during the downward movement. The bearing slides down the feeding ramp 1 under its own weight. When it slides between the guide plates 3, the infrared sensor 14 installed on the top plate 11 at the upper end of the guide column 10 will detect the arrival of the bearing. Subsequently, the telescopic cylinder 12 is activated, and the pressure column 13 at its lower end extends downward to help adjust the position of the bearing and ensure that the bearing accurately enters the conveying channel between the guide plates 3. At the same time, the electric telescopic rod 4 on one side of the guide plate 3 will extend and retract according to the specifications of the bearing. The connecting plate 5 drives the rotating roller 7 to adjust the spacing to accommodate bearings of different sizes. Then, the rotating motor 6 is activated, driving the rotating roller 7 to rotate. The bearing is smoothly conveyed to the flaw detection area by friction, eliminating the need for manual handling and precise alignment, greatly reducing the difficulty of operation. Upon entering the flaw detection stage, the bearing is conveyed by the rotating roller 7 to the bottom of the gantry 8, where the flaw detector 9 at the lower end of the gantry 8 performs comprehensive flaw detection on the bearing. During this process, the rotating roller 7 continuously drives the bearing to rotate, enabling the flaw detector 9 to inspect all parts of the bearing, ensuring the comprehensiveness and accuracy of the inspection. After the inspection is completed, the bearing enters the unloading stage, where the rotating roller 7 conveys the bearing to the unloading ramp 15 at the lower end of the guide plate 3. The sponge pad 16 at the upper end of the unloading ramp 15 acts as a buffer, preventing damage to the bearing due to collisions during unloading. The bearing slides out along the unloading ramp 15 under gravity, completing the unloading operation of the entire inspection process. Throughout the entire process, unloading, conveying, flaw detection, and unloading are all automated or semi-automated, reducing manual intervention. This not only reduces the labor intensity of operators but also improves the efficiency and accuracy of unloading, effectively solving the problem of inconvenient unloading in traditional bearing flaw detectors.

[0032] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may change.
