Description

Technical Field

[0001] The present invention relates to a detection device, and more particularly to an automatic detection device for the overall shape of a rotor part. Background Art

[0002] As a core component of many mechanical devices, the quality of the rotor part is crucial to the overall performance, stability and service life of the device. Whether in automotive engines, motors, compressors, or aircraft engines in the aerospace field, the rotor part is a key function for realizing mechanical motion conversion; once there are quality problems such as dimensional deviations in the shape, insufficient hole position accuracy, or appearance defects in the rotor part, during the high-speed operation of the device, it is extremely easy to cause adverse conditions such as increased vibration, increased noise, and increased component wear. In severe cases, it may even lead to equipment failure and shutdown, which will not only greatly increase the maintenance cost and repair time of the equipment, but also may cause huge economic losses due to production interruption. In some special scenarios, such as the aerospace and medical equipment fields, it may even pose a threat to personal safety; therefore, strict and accurate detection of the overall shape of the rotor part is the key to ensuring its quality and guaranteeing the reliable operation of the device; In the prior art for the detection of rotor parts, traditional detection methods mainly rely on manual operation of measuring tools for one-by-one measurement. Detection personnel usually use tools such as calipers, micrometers, and plug gauges to manually measure the dimensional parameters such as the outer diameter, inner diameter, and height of the rotor part. For the detection of hole positions, auxiliary tools such as templates and positioning pins are required, and the qualification of the hole positions is judged by comparison and trial insertion. This manual detection method requires extremely high skills and work experience of the detection personnel. The detection process is not only time-consuming and laborious, but also has low detection efficiency. In the context of modern large-scale production, the manual detection speed far cannot meet the requirements of the production rhythm, which is easy to cause backlogs of products on the production line and hinder the smooth progress of the production process; In addition, existing detection technologies often can only detect one or several parameters of the rotor part, and it is difficult to achieve comprehensive detection of the overall shape and multiple parameters of the rotor part. To complete a comprehensive quality assessment of the rotor part, multiple different types of detection equipment are required, which not only greatly increases the equipment procurement cost and the occupied space of the production site, but also makes the detection process cumbersome and complex, and is not conducive to overall quality control of the production process.

[0003] Therefore, those skilled in the art are committed to providing an automatic detection device for the overall shape of a rotor part that can effectively solve the above technical problems. Summary of the Invention

In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0029] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "set", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0030] As Figures 1 to 13 shown, an automatic detection device for the overall shape of a rotor part includes an operation table 1; A material transfer mechanism 2 is arranged on the operation table 1 and is used to clamp the rotor to the hole position detection mechanism 3 and transfer it to the material transfer unit 5 after the detection is completed. An appearance detection unit is arranged on the material transfer mechanism 2 and is used to detect the appearance of the rotor after the material transfer mechanism 2 successfully picks up the material. A side hole position detection mechanism 3 is arranged on the operation table 1 and is used to detect the side hole positions on the outer wall of the rotor. A material transfer unit 5 is arranged on the operation table 1 and is used to transfer the rotor that has completed the hole position detection in the direction of the height detection mechanism 6. A height detection mechanism 6 is arranged on the operation table 1 and is used to detect the height of the rotor. An end face hole position detection mechanism 7 is arranged on the operation table 1 and is used to detect the end face hole positions of the rotor. An inner diameter detection mechanism 8 is arranged on the operation table 1 and is used to detect the inner diameter of the rotor. An unloading transfer unit 9 is arranged on the operation table 1 and is used to output the rotor that has completed the inner diameter detection. A material moving mechanism 10 is arranged on the operation table 1 and is used to sequentially move the rotor from the material transfer unit 5 to the height detection mechanism 6, the end face hole position detection mechanism 3, the inner diameter detection mechanism 8, and the unloading transfer unit 9.

[0031] In the present invention, the inner diameter detection mechanism adopts a non-contact type: When the inner diameter detection mechanism is detecting, it will emit a laser beam to the inner diameter wall of the rotor. After the laser beam hits the inner diameter wall, it will be reflected back. The detection mechanism calculates the distance from the emission point of the laser beam to the inner diameter wall by measuring the time difference between the emission and reception of the laser beam and according to the principle of the constancy of the speed of light. Since the position of the emission point of the detection mechanism is relatively fixed, by collecting and analyzing the laser ranging data at multiple different angles, the inner diameter size of the rotor can be calculated. These measurement data will also be transmitted to the data processing unit and compared with the standard size to determine whether the inner diameter of the rotor is qualified.

[0032] For the other height detection mechanisms, end face hole position detection mechanisms, etc. that are specifically described, any device in the prior art that can achieve this detection function can be used. The inner diameter detection mechanism is not limited to using non-contact type.

[0033] The operation table 1 includes a main operation table surface 11 and a side operation table surface 12; The front half of the main operation table surface 11 has a material placing area 13. Two material positioning plates 15 are arranged at the material placing area 13. Four corners of each material positioning plate 15 are detachably connected to the main operation table surface 11 through screws 16. A plurality of material positioning grooves 17 are opened at the upper end of the material positioning plate 15; A material placing plate 18 is placed on the material positioning plate 15. Handles 19 are arranged on both sides of the material placing plate 18. A plurality of material placing cavities 20 are arranged on the material placing plate 18. The lower half sections of each material placing cavity 20 are respectively located in each material positioning groove 17; The material transfer mechanism 2 and the hole position detection mechanism 3 are both arranged on the main operation table surface 11; The material transfer transmission unit 5, the height detection mechanism 6, the end face hole position detection mechanism 7, the inner diameter detection mechanism 8, the discharge transmission unit 9 and the material transfer mechanism 10 are all arranged on the side operation table surface 12.

[0034] The material transfer mechanism 2 includes a top plate 21. Four corners of the top plate 21 are connected to the upper end of the main operation table surface 11 through support rods 22. A transverse guide rail 23 is arranged at the lower end of the top plate 21. A longitudinal guide rail 26 is slidably arranged on the transverse guide rail 23. The longitudinal guide rail 26 makes a reciprocating motion along the length direction of the transverse guide rail 23 through a first driving unit; A material transfer seat 28 is slidably arranged on the longitudinal guide rail 26. The material transfer seat 28 is driven to slide along the length direction of the longitudinal guide rail 26 through a second driving unit. A first air cylinder 29 is arranged on the material transfer seat 28. An output end of the first air cylinder 29 is provided with a mounting block 30.

The first gripping member 33 is rotated by the rotation motor 32, and the first gripping member 33 drives the rotor to rotate. The rotating rotor is detected by the appearance detection unit. The appearance detection unit includes an industrial camera, a light source system, an image acquisition card, and an image processing module. The industrial camera is used to capture the image information of the rotor. Its pixel and resolution need to meet the detection accuracy requirements and can clearly present the fine features on the surface of the rotor. The light source system is used to provide suitable lighting conditions for shooting. By irradiating with light of different angles and intensities, the contrast of defects on the surface of the rotor is enhanced, facilitating the recognition by the camera. The image acquisition card is used to transmit the image data obtained by the camera to the image processing module, ensuring the stability and efficiency of data transmission. The image processing module integrates advanced image analysis algorithms and can process, analyze, and judge the acquired images. When the rotation motor 32 of the material transfer mechanism drives the rotor to rotate, the appearance detection unit starts to work. The specific work includes: The light emitted by the light source system evenly irradiates the surface of the rotor. The industrial camera continuously shoots the rotating rotor from a specific angle to obtain multiple sets of image data. These image data are quickly transmitted to the image processing module through the image acquisition card. The image analysis algorithm in the module preprocesses the images, removes noise interference, enhances the clarity and feature contrast of the images. Subsequently, by comparing with a preset standard image or based on a set defect feature model, the pixel information in the images is analyzed and recognized. Once it is found that there are areas on the surface of the rotor that do not meet the standards, such as abnormal gray values, inconsistent textures, etc., the system will determine that the area is a defect and record relevant information, such as the position, shape, size of the defect, etc., thus realizing the automatic detection of the appearance of the rotor.

The side hole position detection component 39 on the disc 37 works. The detection cylinder 52 pushes the side hole position detection head 51 to slide along the guiding head 50 to detect the side hole positions on the outer wall of the rotor.
