Description
Technical Field
[0001] This utility model relates to the field of mechanical testing equipment technology, and in particular to a batch testing device for surface defects of valve seat parts. Background Technology
[0002] In industrial production, valve seat components are critical parts, and their surface quality directly affects the overall performance and reliability of the product. However, traditional surface defect detection of valve seat components usually relies on manual visual inspection. This method is not only inefficient but also easily affected by human factors, leading to inaccurate and inconsistent inspection results. With the rapid development of industrial automation and intelligent manufacturing, higher demands are placed on the efficiency and accuracy of surface defect detection for valve seat components. Traditional inspection methods can no longer meet the needs of large-scale production; therefore, developing a device capable of automating and batch-detecting surface defects in valve seat components is of significant practical importance.

Through integrated design, this device realizes automated and batch inspection of surface defects of valve seat parts, improves inspection efficiency and accuracy, and meets the high-quality requirements for valve seat parts in industrial production.
[0004] To achieve the above objectives, this utility model provides a batch inspection device for surface defects of valve seat parts, comprising a device body, which includes a housing and a product conveying mechanism. The product conveying mechanism extends through the housing and to both ends for conveying valve seat parts to be inspected. A product placement tray is provided on the conveying plane of the product conveying mechanism for placing the valve seat parts to be inspected. A product surface defect detection mechanism and a lifting mechanism are configured in cooperation within the housing, and the product surface defect detection mechanism and the lifting mechanism are vertically aligned. The product surface defect detection mechanism is positioned above the product conveying mechanism and is used to perform full-area scanning inspection of the surface of the valve seat parts placed on the product placement tray. The lifting mechanism is positioned on the product conveying mechanism and is used to drive the product placement tray to move up and down. The housing is also equipped with a three-color indicator light and a control display screen, which are used to indicate the working status of the device and display the operation interface, detection parameters, and results, respectively.
[0005] In operation, this invention first places the valve seat part to be inspected on a product placement tray and transports it to the inspection station inside the housing via a product conveying mechanism.

The second drive assembly then drives the mounting plate along... The vertical guide rail lifts and lowers, driving the inspection camera to scan the entire surface of the lifted part. Sensors detect the position and status of the valve seat part, providing precise positioning signals for the inspection camera. The inspection camera, a high-resolution industrial camera, acquires images of the valve seat part surface and detects surface defects through image processing technology. The inspection results are displayed in real time on the control screen, while three-color indicator lights display different colors according to the inspection status. Operators can set inspection parameters, view historical inspection data, and start / stop devices through the touch screen interface of the control screen.

The cooperation of the first and second drive components in the product surface defect detection mechanism allows the detection camera to move in three-dimensional space, achieving full-area scanning detection of the valve seat part surface, improving detection efficiency and accuracy. The lifting mechanism, through the coordinated design of the connecting plate, connecting rod, limit block, and lifting drive component, achieves stable lifting of the product placement tray, improving the flexibility and adaptability of the detection. Simultaneously, the protrusions and anti-slip layer effectively prevent product placement tray displacement, improving detection accuracy. The control display screen integrates the control system and human-machine interface, displaying detection images and data in real time, and supporting parameter settings and automated process control, significantly improving the device's intelligence level and ease of operation.
