Description
Technical Field
[0001] The utility model relates to the technical field of forging surface flaw detection, in particular to a forging surface flaw detection device. Background Art
[0002] Forgings refer to workpieces or blanks obtained by forging and deforming metal blanks. In the field of deep-sea oil production, a large number of forgings are used for the construction of equipment platforms or the manufacture of oil production equipment. Forgings can be divided into cold forging, warm forging and hot forging according to the temperature of the blank during processing. The difference in the complexity of the geometric structure of forgings determines that their die forging process and die design are significantly different. Forgings can use the actual pressure on the metal blank to cause it to undergo plastic deformation and change its mechanical properties. The forging shell can eliminate the looseness and holes in the metal and improve its mechanical properties.
[0003] The forgings used for deep-sea oil production have extremely high quality requirements, especially whether there are scratches on the surface of the forgings, which directly determines whether the forgings can be used. When performing surface flaw detection on forgings, due to the different sizes of forgings, the distance between the detector and the forging can be adjusted, so that the flaw detection work can be performed more accurately. Secondly, the sizes of forgings are different, so when the forgings pass under the detector, it is necessary to keep the forgings directly under the detector, so that the forgings can be inspected in all directions. Finally, before performing surface flaw detection on the forgings, the dust on the surface of the forgings needs to be cleaned to avoid the dust from affecting the detection results. Therefore, a surface flaw detection device for forgings is proposed to address the above problems. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. In the utility model, the height of the detector under the sliding plate can be adjusted by setting the threaded hole, screw, sliding plate, slider and groove. When the size of the forging is different, the distance between the detector and the forging needs to be adjusted. With the help of the screw and the threaded hole, the detector can be kept at a suitable detection height, so that the forging can be better detected;
[0013] 2. In the utility model, the horizontal position of the forging in the fixed frame can be limited by the bar-shaped hole, lead screw, handle, moving block, straight rod and rotating column.

Through the action of the rotating column, the forging can be limited to the right below the detector to ensure the detection accuracy;
[0014] 3. In the utility model, the forgings to be inspected can be cleaned by setting the fixing rod, connecting rod, positioning bolt, rotating plate, motor, rotating shaft, and brush roller. The brush roller will continuously clean the forgings and remove dust on the surface under the rotation of the rotating shaft driven by the motor. The height of the brush roller can be adjusted by the fixed height of the positioning bolt in the positioning groove to accommodate forgings of different sizes. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] A fixing rod 17 is fixedly connected to the outside of the fixing frame 2, and a connecting rod 18 is rotatably connected to the outside of the fixing rod 17. The end of the connecting rod 18 away from the fixing rod 17 is fixedly connected to a rotating plate 20, and a motor 21 is fixedly connected to the outside of the rotating plate 20. A rotating shaft 22 is fixedly connected to the power output end of the motor 21, and a brush roller 23 is fixedly connected to the outside of the rotating shaft 22. Positioning grooves 24 are provided on both sides of the fixing frame 2; the width of the slider 7 is smaller than the width of the slide groove 8, and the slider 7 slides up and down in the slide groove 8; the width of the moving block 13 is smaller than the width of the strip hole 10, and the moving block 13 and the strip hole 10 are slidably connected; the rotating shaft 22 and the rotating plate 20 are rotatably connected.
[0026] Working process: When the device needs to inspect forgings, the device is first installed in a suitable position, and an external power supply provides power to the electrical equipment of the device. A fixing frame 2 is fixed on the top of the base 1. The screw 4 can adjust the height of the sliding plate 5 through the threaded hole 3. The screw 4 and the sliding plate 5 are rotatably connected. The bottom of the screw 4 is in the groove 6 of the sliding plate 5. The outer ends of the sliding plate 5 are fixedly connected with sliders 7. Slide grooves 8 are provided on both sides of the fixing frame 2. The sliding plate 5 moves up and down in the slide grooves 8 through the sliders 7 at both ends. The slide grooves 8 are used to adjust the height of the sliding plate 5. The sliding plate 5 plays a limiting role. A detector 9 is installed below the sliding plate 5. The detector 9 checks the surface of the forging to check whether there are any scratches, etc. When the forging is detected in the fixed frame 2, it is necessary to keep the forging directly below the detector 9. A lead screw 11 is rotatably connected in the strip hole 10. The outer side of the lead screw 11 is threadedly connected to a moving block 13. Since the thread directions of the front and rear halves of the lead screw 11 are inconsistent, when the handle 12 is turned, the two moving blocks 13 either move toward the center of the lead screw 11 at the same time, or move away from the center of the lead screw 11 at the same time. The two moving blocks 13 are arranged in a central symmetrical manner, so as to ensure that the straight rods 14 at the top of the two moving blocks 13 are arranged in a central symmetrical manner in the fixed frame 2. A rotating column 15 is rotatably connected on the outside of the straight rod 14. The rotating column 15 contacts the forging to limit the forging to move to both sides, and can limit the forging to be directly below the detector 9, so as to obtain more accurate detection data. A fixed rod 17 is fixed on the outside of the fixed frame 2, and a connecting rod 18 is rotatably connected outside the fixed rod 17. A rotating plate 20 is fixed on one end of the connecting rod 18, and a motor 21 is fixed on the outside of the rotating plate 20. A rotating shaft 22 is connected to the motor 21. The other end of the rotating shaft 22 is rotatably connected to another rotating plate 20, and the brush roller 23 is fixed on the outside of the rotating shaft 22. When the forging needs to be cleaned, the motor 21 is started, and the motor 21 drives the rotating shaft 22 and the brush roller 23 to rotate. The brush roller 23 cleans the surface of the forging to remove dust, etc. There are also positioning grooves 24 on both sides of the fixed frame 2, and the positioning bolts 19 pass through the positioning grooves 24 and the connecting rod 18. By changing the position of the positioning bolts 19 in the positioning grooves 24, the relative height of the brush roller 23 can be changed to adapt to forgings of different heights for better cleaning.
