Description

Technical Field

[0001] This utility model relates to the field of ultrasonic flaw detection technology, specifically to an ultrasonic flaw detector. Background Technology

[0002] Ultrasonic flaw detection technology is widely used to detect internal defects (such as cracks and pores) in industrial workpieces. However, existing ultrasonic flaw detectors suffer from the following problems: they largely rely on manual assistance for workpiece handling, flipping, and positioning, which not only increases the workload of operators but also easily reduces detection accuracy due to human error; furthermore, the adaptability of the flaw detection components to workpieces of different shapes and sizes is poor, making it difficult to efficiently complete comprehensive flaw detection of multi-faceted and multi-type workpieces, thus affecting detection efficiency and quality. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an ultrasonic flaw detector, which is equipped with a transmission component, two centrally symmetrical robotic arms, and a flaw detection component working together. This solves the problems of existing ultrasonic flaw detectors, such as reliance on manual operation, insufficient flaw detection positioning accuracy, and poor adaptability to different workpieces.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an ultrasonic flaw detector, comprising a transmission component, wherein a robotic arm and a flaw detection component are configured on the transmission component.

[0005] The transmission assembly includes a transmission box containing transmission rollers for transporting workpieces. Multiple transmission rollers can stably receive and transport workpieces. A support is fixedly connected to each of the four corners of the bottom of the transmission box, providing stable support. A side plate is fixedly connected to each side of the transmission box, with inlet / outlet slots between the side walls for easy workpiece entry and exit from both ends of the transmission box. A control console is also installed on the transmission box to centrally control the entire flaw detection process. Two robotic arms are fixedly installed at the front and rear ends of the middle of the transmission box, arranged symmetrically to facilitate clamping and flipping of workpieces from different directions.

[0006] The robotic arm includes a first electric rotating base mounted on the transmission box, a first electric arm connected to the first electric rotating base, and a second electric arm connected to the first electric arm. The first electric arm and the second electric arm cooperate to achieve multi-dimensional extension and angle adjustment.

[0007] The flaw detection assembly includes outer covers fixedly installed on both sides of the top of the transmission box, which protect the internal components such as ultrasonic flaw detectors. The outer covers have mounting slots, in which ultrasonic flaw detectors are installed. An ultrasonic flaw detector probe is installed at the bottom of each ultrasonic flaw detector for emitting and receiving ultrasonic waves to detect defects in the workpiece. A U-shaped bracket is fixedly connected between the tops of the two outer covers, and a locator is fixedly installed on the inner top wall of the U-shaped bracket to accurately locate the flaw detection area of ​​the workpiece.

[0008] As a further improvement of this utility model: multiple transmission rollers are evenly spaced along the length of the transmission box, and the multiple transmission rollers are driven by a motor to achieve synchronous rotation, ensuring that the workpiece moves smoothly during the transmission process and avoiding deviation.

[0009] As a further embodiment of this utility model: the robotic arm includes a first electric rotating seat mounted on the transmission box, a first electric arm mounted on the rotating end of the first electric rotating seat, and a second electric arm mounted on the end of the first electric arm away from the first electric rotating seat.

[0010] As a further embodiment of this utility model: a second electric rotating seat is installed at the end of the second electric arm away from the first electric arm, and an electric gripper is installed at the end of the second electric rotating seat away from the second electric arm. The second electric rotating seat can drive the electric gripper to rotate in the vertical plane, which facilitates the adjustment of the workpiece's posture.

[0011] As a further improvement of this utility model, the electric gripper is an adaptive gripper that can automatically adjust the clamping force and angle according to the shape of the workpiece, and can stably clamp workpieces of different shapes and sizes, thus improving adaptability.

[0012] As a further improvement of this utility model: the ultrasonic flaw detection probe is connected to the ultrasonic flaw detector by a signal, and the ultrasonic flaw detection probe is a replaceable high-frequency probe, which can be replaced according to different flaw detection needs to meet the detection requirements of diverse workpieces.

[0013] As a further improvement of this utility model, the positioner is a laser positioner, which is used to locate the flaw detection position of the workpiece and to accurately mark the flaw detection area through the laser beam, thereby improving the accuracy of flaw detection.

[0014] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the workpiece is automatically transported by a transmission component, and two centrally symmetrical robotic arms work together to automatically clamp and flip the workpiece. Two flaw detection components can sequentially detect flaws on both sides of the workpiece. The whole process is highly automated, reducing manual intervention, which not only reduces the workload of operators but also avoids human error, effectively improving flaw detection accuracy and detection efficiency.

[0015] In this invention, the ultrasonic flaw detector uses a replaceable high-frequency probe, which allows the flaw detector to be adapted to workpieces of different sizes and shapes. It can also perform flaw detection on multiple sides of the workpiece, improving the equipment's versatility and adaptability to various types of workpieces, and further meeting diverse flaw detection needs.
