Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a real-time detection device for surface defects of high-temperature forgings. Background Art

[0002] In the modern industrial production process, visual inspection has been widely used in all walks of life. With the development of industry, the demand for visual inspection of some products is increasing. At present, manual contact inspection is still the main method in the forging production industry. Usually, workers directly measure the size of forgings with handheld calipers or make a rough estimate of the size of forgings by visual inspection. The work efficiency is low, the labor intensity is high, the labor cost is high, and it will lead to large cold processing allowances, resulting in low raw material utilization, which seriously affects and restricts the development of enterprises. Now some factories have begun to use visual inspection instead of manual inspection, but some forgings need to be inspected at high temperatures.

[0003] At present, most of the visual inspection devices used in factories use video acquisition devices to monitor the outer wall of the forging in real time, upload it to the cloud, and then use the cloud to analyze and calculate whether there are any defects on the surface. However, in actual use, the distance between the video acquisition device and the forging is relatively close to ensure the clarity of the acquired image. Since the surface temperature of the forging is relatively high after processing, the hot air generated will surround the video acquisition device, and the generated hot air will cause thermal interference to the video acquisition device, affecting the quality and accuracy of the image. Therefore, it is necessary to redesign the real-time detection device for surface defects of high-temperature forgings to address the above problems. Utility Model Content

[0021] Reference Figure 3 A reciprocating screw 13 is rotatably connected to the bottom of the device cavity 12, a screw sleeve 14 is threadedly connected to the threaded section of the reciprocating screw 13, and a limiting block 15 is fixedly connected to the end of the reciprocating screw 13. The radius of the limiting block 15 is larger than the radius of the reciprocating screw 13. The reciprocating screw 13 can drive the piston 17 to slide reciprocatingly through the screw sleeve 14, and the limiting block 15 can limit the sliding position of the screw sleeve 14.

[0022] Refer to the figure Figure 3The inner wall of the device cavity 12 and the outer wall of the screw sleeve 14 are both square, and the outer walls on both sides of the screw sleeve 14 are in contact with the inner wall of the device cavity 12. The device cavity 12 limits the position, which can ensure that the screw sleeve 14 slides back and forth in the vertical direction of the Y axis.

[0023] Refer to the figure Figure 2 The lower end of the fixed plate 4 is rotatably connected with an incomplete gear 9 and a gear 10. The incomplete gear 9 is coaxially fixedly connected to the blade 5. The gear 10 is coaxially fixedly connected to the reciprocating screw 13.

[0025] In the utility model, the specific function of the device is as follows: when using the device, the barrel 1 is made of heat-insulating material, which can effectively reduce the heat transfer of the forging. At the same time, the coolant in the heat dissipation cavity 6 can further reduce the surface and internal temperature of the barrel 1. At the same time, the detection probe 2 can upload the surface condition of the forging to the cloud for analysis and detection. When the internal temperature of the barrel 1 is high, the servo motor 8 can be started. The servo motor 8 drives the incomplete gear 9 to rotate and simultaneously drives the blade 5 to rotate. The operation of the blade 5 can make the air inside the barrel 1 flow, which helps to reduce the internal space temperature of the barrel 1, and in the incomplete gear 9, the blade 5 can rotate. While the gear 9 rotates, the meshing with the gear 10 drives the reciprocating screw 13 to rotate synchronously. The reciprocating screw 13 drives the screw sleeve 14 and the piston 17 to slide back and forth in the device cavity 12. During sliding, the coolant in the heat dissipation cavity 6 can be drawn into and then discharged into the heat dissipation cavity 6. In this way, the coolant is in a flowing state, which can enhance the cooling effect of the coolant. At the same time, after the coolant enters the device cavity 12, it can be cooled by the cooler 16 to ensure the insulation effect of the coolant. Combining a variety of insulation and cooling methods can reduce the influence of the hot air generated by the forging on the detection probe 2, thereby ensuring the quality and accuracy of the image.
