Description

Technical Field

[0001] This utility model relates to the technical field of welding inspection devices, specifically a visual welding inspection device. Background Technology

[0002] Welding inspection equipment is a key device used to assess welding quality, identify defects, and ensure the integrity of welded structures. It is widely used in manufacturing, construction, aerospace, energy, and other fields.

[0003] A welding inspection device is needed during the workpiece welding process. Chinese utility model patent CN210701244U discloses a welding inspection device, which includes a workbench, a finished product box, a controller, a drive mechanism, and a testing fixture. The fixture body is fixedly installed on the workbench, and a sensor is installed on the fixture body and connected to the controller. The controller is connected to the drive mechanism, and the drive mechanism is connected to the finished product box. The sensor is used to detect whether the parts are welded in place, and sends a control signal to the controller when the parts are detected to be welded in place. The controller is used to control the drive mechanism to open the finished product box when it receives the control signal. Compared with the prior art, this utility model can accurately detect whether there is a missing weld or incomplete weld in the welded finished product because it uses a sensor installed on the fixture body and a controller connected to the finished product box through the drive mechanism. This prevents defective products from being packed, avoids defective products from flowing out, and improves the yield rate.

[0004] This invention can accurately detect whether there are any missing welds or incomplete welds in the finished product. However, existing welding inspection devices are not convenient for weld flaw detection. At the same time, they cannot adjust the viewing angle, making it impossible to confirm the weld quality of the workpiece. Furthermore, they are not convenient for workers to observe the appearance quality of the workpiece after welding, resulting in poor applicability. Therefore, a visual welding inspection device is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a visual welding inspection device that has advantages such as weld flaw detection and adjustable viewing angle, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A visual welding inspection device includes an inspection frame, wherein the inspection frame is provided with an inspection adjustment component for weld flaw detection and adjusting the viewing angle.

[0008] The detection and adjustment assembly includes electric push rods fixedly connected to the left and right sides of the detection frame. The output shaft of the electric push rod is fixedly connected to a moving plate. A first ultrasonic flaw detector is fixedly connected to the outer surface of the moving plate. An inclined plate is fixedly connected to the top of the moving plate. A second ultrasonic flaw detector is fixedly connected to the outer side of the inclined plate. A machine platform is fixedly connected to the inner bottom wall of the detection frame. A drive motor is fixedly connected to the bottom of the machine platform. The output shaft of the drive motor is fixedly connected to the detection platform. A fixing assembly for stabilizing the workpiece is provided on the top of the detection platform.

[0009] Furthermore, the fixing assembly includes a fixing frame fixedly connected to the top of the testing platform, a sliding rod and a spring fixedly connected to the inner side of the fixing frame, a clamping fixing plate slidably connected to the outer surface of the sliding rod, and a magnetic chuck glued to the middle of the top of the testing platform.

[0010] Furthermore, the sliding rod passes through the spring, and the magnetic chuck is a magnet.

[0011] Furthermore, the inner diameter of the machine tool is larger than the outer diameter of the testing table, and both the machine tool and the testing table are circular in shape.

[0012] Furthermore, a cylinder is fixedly connected to the top of the detection frame, and a lifting plate is fixedly connected to the output shaft of the cylinder.

[0013] Furthermore, a cleaning cylinder is fixedly connected to the bottom of the lifting plate, and a brush sleeve is adhered to the inner side of the cleaning cylinder.

[0014] Furthermore, the bottom end of the cleaning cylinder has an opening for the workpiece to enter, and the outer side of the brush sleeve is provided with plastic bristles.

[0015] Furthermore, a display controller is fixedly installed on the outside of the detection frame, and both the first ultrasonic flaw detector and the second ultrasonic flaw detector are electrically connected to the display controller.

[0016] Compared with the prior art, the present invention provides a visual welding inspection device, which has the following beneficial effects:

[0017] 1. This visual welding inspection device, through its inspection and adjustment components, includes an electric push rod that can push a moving plate and an inclined plate closer to the workpiece. This allows a first ultrasonic flaw detector to inspect the weld quality around the workpiece, and a second ultrasonic flaw detector to inspect the weld quality at the top of the workpiece. During this process, a drive motor can slowly rotate the inspection table, thereby adjusting the orientation and viewing angle of the workpiece in real time. This ensures that the first and second ultrasonic flaw detectors can better cover the inspected welds, and also facilitates the observation of the workpiece's appearance quality after welding. Compared to existing welding inspection devices, this device has better applicability.

[0018] 2. This visual welding inspection device uses a fixed assembly. When the operator moves the clamping plate, the spring is compressed, and the clamping plate slides continuously on the outer surface of the sliding rod. During this process, the workpiece is positioned on top of the magnetic chuck. Then, the clamping plate is released, and the spring returns to its original state, so that the workpiece is finally clamped and fixed between the two clamping plates to ensure its positional stability and avoid inspection deviation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 3This embodiment of a visual welding inspection device includes an inspection frame 1. Inside the inspection frame 1 is an inspection adjustment assembly for weld flaw detection and adjusting the viewing angle. The inspection adjustment assembly includes electric push rods 2 fixedly connected to the left and right sides of the inspection frame 1. The output shaft of the electric push rods 2 is fixedly connected to a moving plate 3. A first ultrasonic flaw detector 4 is fixedly connected to the outer surface of the moving plate 3. An inclined plate 5 is fixedly connected to the top of the moving plate 3. A second ultrasonic flaw detector 6 is fixedly connected to the outer side of the inclined plate 5. A machine platform 7 is fixedly connected to the inner bottom wall of the inspection frame 1. A drive motor 8 is fixedly connected to the bottom of the machine platform 7. The output shaft of the drive motor 8 is fixedly connected to an inspection table 9. A fixing assembly for stabilizing the workpiece is provided on the top of the inspection table 9. The electric push rods 2 can push the moving plate 3 and the inclined plate 5 closer to the workpiece, enabling the first ultrasonic flaw detector 4 to detect the weld quality around the workpiece, and the second ultrasonic flaw detector 6 to detect the weld quality at the top of the workpiece.

[0025] During this process, the drive motor 8 can drive the inspection table 9 to rotate slowly, thereby adjusting the orientation and viewing angle of the workpiece in real time, so that the first ultrasonic flaw detector 4 and the second ultrasonic flaw detector 6 can better cover the inspection weld. At the same time, it is convenient for staff to observe the appearance quality of the workpiece after welding. Compared with existing welding inspection devices, it has better applicability.

[0026] It should be noted that this application can use a synchronization controller or other synchronization device to ensure that the output shafts of the two electric push rods 2 extend and retract simultaneously, thereby achieving synchronous operation. These synchronization devices are common and mature in the field of electric control, so they will not be described in detail in the specific embodiments.

[0027] In this embodiment, the fixing component includes a fixing frame 10 fixedly connected to the top of the testing platform 9. A sliding rod 11 and a spring 12 are fixedly connected to the inner side of the fixing frame 10. A clamping fixing plate 13 is slidably connected to the outer surface of the sliding rod 11. A magnetic chuck 14 is glued to the middle of the top of the testing platform 9. When the operator moves the clamping fixing plate 13, the spring 12 is compressed, and the clamping fixing plate 13 slides continuously on the outer surface of the sliding rod 11.

[0028] During this process, the workpiece is positioned on top of the magnetic chuck 14. Then, the clamping plate 13 is released, allowing the spring 12 to return to its original state, so that the workpiece is finally clamped and fixed between the two clamping plates 13 to ensure its positional stability and avoid detection offset.

[0029] It should be noted that the sliding rod 11 passes through the spring 12, and the magnetic chuck 14 is a magnet.

[0030] Specifically, the inner diameter of the machine base 7 is larger than the outer diameter of the testing table 9, and both the machine base 7 and the testing table 9 are circular in shape.

[0031] In this embodiment, a cylinder 15 is fixedly connected to the top of the detection frame 1, a lifting plate 16 is fixedly connected to the output shaft of the cylinder 15, a cleaning cylinder 17 is fixedly connected to the bottom of the lifting plate 16, and a brush sleeve 18 is bonded to the inner side of the cleaning cylinder 17. Before detection, the cylinder 15 can drive the cleaning cylinder 17 to move vertically downward through the lifting plate 16, so that the cleaning cylinder 17 covers the workpiece. Then, the cylinder 15 is controlled to drive the cleaning cylinder 17 to move up and down rapidly, so that the welding slag on the workpiece is brushed off by the brush sleeve 18 to clean the workpiece.

[0032] It should be noted that the bottom of the cleaning cylinder 17 has an opening for the workpiece to enter, and the outer side of the brush sleeve 18 is provided with plastic bristles.

[0033] Specifically, a display controller is fixedly installed on the outside of the detection frame 1, and both the first ultrasonic flaw detector 4 and the second ultrasonic flaw detector 6 are electrically connected to the display controller.

[0034] The working principle of the above embodiments is as follows:

[0035] In use, the operator first needs to move the clamping plate 13 to compress the spring 12. The clamping plate 13 slides continuously on the outer surface of the sliding rod 11, positioning the workpiece on top of the magnetic chuck 14. Then, the clamping plate 13 is released, allowing the spring 12 to return to its original state, so that the workpiece is finally clamped and fixed between the two clamping plates 13 to ensure its positional stability. After the workpiece is stably fixed, the electric push rod 2 is activated, which can push the moving plate 3 and the tilting plate 5 closer to the workpiece, so that the first ultrasonic flaw detector 4 can detect the weld quality around the workpiece, and the second ultrasonic flaw detector 6 can detect the weld quality at the top of the workpiece. During this process, the drive motor 8 is activated and controlled to drive the inspection table 9 to rotate slowly, thereby adjusting the orientation and viewing angle of the workpiece in real time, so that the first ultrasonic flaw detector 4 and the second ultrasonic flaw detector 6 can better cover the weld to be inspected, and at the same time, it is convenient for the operator to observe the appearance quality of the workpiece after welding.

[0036] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
