Description

Technical Field

[0001] The present invention relates to the technical field of aluminum ingot quality inspection, and particularly to a quality inspection device for aluminum ingots after casting and forming. Background Art

[0002] An aluminum ingot is a metal intermediate product mainly composed of aluminum, which is obtained by pouring molten aluminum liquid into a mold and cooling and solidifying it. It is widely used in fields such as automobiles, aviation, construction, and electricity. It is one of the basic raw materials in the aluminum processing industry. According to different mold structures and processing uses, the shapes of aluminum ingots are diverse. One of the more common ones is the cuboid-shaped aluminum ingot, which is convenient for stacking, storage, transportation, and further processing. After the aluminum ingot is formed, in order to ensure that it meets national standards or customer requirements, a series of quality inspections need to be carried out. Among them, chemical composition analysis is one of the important inspection items for measuring the quality of aluminum ingots. By quantitatively analyzing the key alloy elements in the aluminum ingot, it is judged whether they reach the specified ratio to prevent the performance of subsequent products from being affected due to uneven or excessive components. During the actual inspection process, the instrument probe usually needs to directly contact the surface of the aluminum ingot body to obtain accurate data. However, during the cooling process after high-temperature casting of aluminum, its surface will quickly react with air to form a dense aluminum oxide layer. This oxide layer not only has high hardness and strong adhesion, but also has a rough and uneven surface, poor electrical conductivity and sound wave permeability, and will interfere with the sound waves in chemical analysis detection, such as abnormal excitation signals, chaotic echoes, and poor coupling, affecting the detection accuracy.

[0003] During the inspection of aluminum ingots, in order to obtain more comprehensive and reliable inspection data, it is necessary to inspect multiple different sides of the aluminum ingot. Standard aluminum ingots are large in volume and heavy in weight, and usually need to be operated on the ground or on a workbench. When turning the aluminum ingot, it is not only laborious but also has potential safety hazards. Moreover, after turning, the aluminum ingot is not placed stably and is easy to shake, which is not conducive to the stable contact and accurate measurement of the inspection equipment and affects the inspection deviation. At the same time, the oxide layer on the surface of the aluminum ingot during the inspection process will further affect the accuracy of the inspection results. At present, during inspection, tools such as angle grinders, grinding wheels, or electric steel brushes are mostly used in cooperation with manual labor for pre-grinding. It is difficult to grind the inspection surface flat during the grinding process, affecting the subsequent inspection results. Summary of the Invention

[0004] The present invention provides a quality inspection device for aluminum ingots after casting, which solves the technical problems that before the inspection of aluminum ingots, the surface pretreatment of the measured points is required. It is a common method to manually use tools such as angle grinders and grinding wheels to polish the oxide layer. However, since it is difficult to evenly control the polishing force, it is easy to cause incomplete removal of the oxide layer or inconsistent depths, affecting the accuracy and stability of the inspection results. In addition, to obtain comprehensive data, multiple sides of the aluminum ingot need to be inspected. However, standard aluminum ingots are large in volume and heavy in weight, making it laborious and dangerous to turn them over on the ground. After turning over, the aluminum ingots are not easy to be stably placed, which is also not conducive to the effective contact and accurate measurement of the inspection equipment.

[0005] A quality inspection device for aluminum ingots after casting provided by the present invention includes a support frame. A sliding part is arranged on the upper part of the support frame. A grinding type inspection part for grinding the oxide layer on the surface of the inspection point area of the aluminum ingot to facilitate inspection is arranged on the sliding part. A positioning mechanism for clamping the aluminum ingot and adjusting the orientation of the aluminum ingot to facilitate the inspection of different areas of the aluminum ingot by the grinding type inspection part is arranged on the support frame. The grinding type inspection part includes a mounting seat installed at the lower part of the sliding part through a telescopic unit, a rotating cylinder rotatably connected to the mounting seat in an embedded manner, a driving rotation unit jointly arranged between the rotating cylinder and the telescopic unit for driving the rotating cylinder to rotate, and an inspection instrument installed at the lower part of the driving rotation unit.

[0010] In a possible implementation, the expanding and moving assembly includes a plurality of strip-shaped mounting grooves circumferentially and equidistantly arranged at the lower part of the rotating cylinder and connecting rods respectively hinged in each strip-shaped mounting groove. The lower end of the connecting rod is hinged to the upper side of the corresponding arc-shaped grinding plate. An auxiliary pull rod parallel to the connecting rod is hinged to the upper end face of the arc-shaped grinding plate, and the upper end of the auxiliary pull rod is hinged in the strip-shaped mounting groove.

[0011] In a possible implementation, a hole groove is formed on the upper end face of the arc-shaped grinding plate, and a reset spring is fixedly connected between the hole groove and the connecting rod.

[0012] In a possible implementation, the auxiliary grinding member includes a fitting groove and a rectangular grinding plate. For any two symmetrically arranged arc-shaped grinding plates, a fitting groove is formed at the lower end of one of them, and a rectangular grinding plate is fixedly connected to the lower end of the other one.

Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0030] Please refer to Figure 1 , the present invention provides a technical solution: a quality detection device for aluminum ingots after casting and forming, including a bracket frame 1, a sliding part 2 is arranged on the upper part of the bracket frame 1, and a grinding type detection part 3 for grinding the oxide layer on the surface of the detection point area of the aluminum ingot for easy detection is arranged on the sliding part 2. A position adjustment mechanism 4 for clamping the aluminum ingot and adjusting the orientation of the aluminum ingot to facilitate the detection of different areas of the aluminum ingot by the grinding type detection part 3 is arranged on the bracket frame 1.

[0031] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, in this embodiment, the grinding type detection unit 3 includes a mounting base 32 installed at the lower part of the sliding part 2 through a telescopic unit 31, a rotating cylinder 33 rotatably connected to the mounting base 32 in an embedded manner, a driving and rotating unit 34 jointly arranged between the rotating cylinder 33 and the telescopic unit 31 for driving the rotating cylinder 33 to rotate, and a detector 35 installed at the lower part of the driving and rotating unit 34. An expanding and moving assembly 36 is arranged at the lower part of the rotating cylinder 33. A plurality of arc-shaped grinding plates 37 are circumferentially and equidistantly installed at the lower part of the expanding and moving assembly 36. A supplementary grinding part 38 for filling and friction in the area vacated between the arc-shaped grinding plates 37 is jointly arranged between two adjacent arc-shaped grinding plates 37 on the left and right. The expanding and moving assembly 36 is used for moving the arc-shaped grinding plates 37 away from the axis of the rotating cylinder 33 while the arc-shaped grinding plates 37 are rotating, so as to facilitate the detector 35 to contact the surface of the aluminum ingot after being ground for detection.

[0032] Please refer to Figure 2 , the telescopic unit 31 includes an electric telescopic rod 311 fixedly connected to the lower end face of the sliding seat 23 and two strip-shaped frames 312 symmetrically and fixedly connected to the upper end face of the mounting base 32 on the left and right. The lower end of the electric telescopic rod 311 is fixedly connected with a bearing seat 313. Slide plates 314 slidably arranged in the strip-shaped frames 312 are fixedly connected to the left and right end faces of the bearing seat 313 respectively. A top spring is fixedly connected between the slide plate 314 and the lower cavity wall of the strip-shaped frame 312.

[0033] Please refer to Figure 2 and Figure 3 , the driving and rotating unit 34 includes a driving motor 341 fixedly connected to the lower end face of the bearing seat 313. A transmission shaft 342 is fixedly connected to the end of the output shaft of the driving motor 341. The detector 35 is installed at the lower end of the transmission shaft 342. A plurality of guide grooves 343 are circumferentially and equidistantly formed in the inner cavity of the rotating cylinder 33. A plurality of guide plates 344 corresponding to the guide grooves 343 and slidably connected in the guide grooves 343 respectively are circumferentially and equidistantly fixedly connected to the outer wall of the transmission shaft 342.

[0034] Please refer to Figure 3 and Figure 4 , the expanding and moving assembly 36 includes a plurality of strip-shaped installation grooves 361 circumferentially and equidistantly formed at the lower part of the rotating cylinder 33 and connecting rods 362 respectively hinged in each strip-shaped installation groove 361. The lower end of the connecting rod 362 is hinged to the upper side of the corresponding arc-shaped grinding plate 37. A supplementary pull rod 363 parallel to the connecting rod 362 is hinged to the upper end face of the arc-shaped grinding plate 37. The upper end of the supplementary pull rod 363 is hinged in the strip-shaped installation groove 361. A hole groove is formed in the upper end face of the arc-shaped grinding plate 37. A return spring 5 is fixedly connected between the hole groove and the connecting rod 362. The supplementary grinding part 38 includes a fitting groove 381 and a rectangular grinding plate 382. For any two symmetric arc-shaped grinding plates 37, a fitting groove 381 is formed at the lower end of one, and a rectangular grinding plate 382 is fixedly connected to the lower end of the other. The fitting groove 381 and the rectangular grinding plate 382 are slidably connected.

[0035] During detection, first place the aluminum ingot into the positioning mechanism 4. Then, manually move the sliding seat 23 to drive the grinding detection unit 3 to move to a suitable position of the aluminum ingot. Initially, the arc-shaped grinding plates 37 are gathered together. The arc shape of the arc-shaped grinding plates 37 makes the splicing more in line with the rotation trajectory after splicing. The edge of the ground area is smooth and has no serrated feeling, which is convenient for the subsequent alignment of the detector 35. Then, control the electric telescopic rod 311 to extend to drive the bearing seat 313 to move downward. The bearing seat 313 then drives the drive motor 341 and the slide plate 314 to move downward. The slide plate 314 drives the strip-shaped frame 312 to move downward through the top spring. The strip-shaped frame 312 then drives the mounting seat 32 to move downward. The mounting seat 32 then drives the rotating cylinder 33 to move downward. The drive motor 341, the transmission shaft 342, and the rotating cylinder 33 move downward as a whole. At the same time, control the drive motor 341 to operate to drive the transmission shaft 342 to rotate. The transmission shaft 342 then drives the guide plate 344 to rotate. The guide plate 344 drives the rotating cylinder 33 to rotate through the guide groove 343. The rotating cylinder 33 drives the arc-shaped grinding plates 37 to rotate through the connecting rod 362. When the arc-shaped grinding plates 37 move downward and contact the surface of the aluminum ingot, the arc-shaped grinding plates 37 rotate and rub on the surface of the aluminum ingot to remove the oxide layer on the surface of the aluminum ingot.

[0036] While the rotating cylinder 33 rotates and continues to move downward to push the connecting rod 362 to rotate outwardly around the hinge point in the strip-shaped mounting groove 361. The connecting rod 362 then drives the arc-shaped grinding plates 37 to gradually move away from the axis of the rotating cylinder 33. Through the auxiliary pull rod 363 moving synchronously with the connecting rod 362, the arc-shaped grinding plates 37 are always in a horizontal state during the outward movement. (When the arc-shaped grinding plates 37 move outward, the angle between them and the connecting rod 362 will gradually decrease, thereby squeezing the return spring 5 to contract. The return spring 5 is compressed and enters the hole groove). While one of the arc-shaped grinding plates 37 rotates, it will also drive the rectangular grinding plate 382 to rotate synchronously. During the rotation of the rectangular grinding plate 382, the oxide layer in the empty area between the arc-shaped grinding plates 37 is removed by friction. The outward movement of the arc-shaped grinding plates 37 drives the rectangular grinding plate 382 to slide in the fitting groove 381. When the arc-shaped grinding plates 37 move outward and away to the final position, the arc-shaped grinding plates 37 completely move away from directly below the rotating cylinder 33. At the same time, the rectangular grinding plate 382 also moves away from directly below the rotating cylinder 33 synchronously with the rotating cylinder 33. At this time, the rotating cylinder 33 moves downward and touches the surface of the aluminum ingot.

[0037] Then control the drive motor 341 to stop running. The electric telescopic rod 311 continues to extend to push the bearing seat 313 to continue moving downward. The bearing seat 313 drives the slide plate 314 to move downward in the strip-shaped frame 312, squeezing the top spring to be compressed. The bearing seat 313 then drives the detector 35 to move downward through the drive motor 341 and the transmission shaft 342 until the detector 35 touches the surface of the aluminum ingot for detection and analysis.

[0038] It should be noted that the detector 35 is an existing direct-reading spectrometer, and its detection principle is also an existing technology. The detection principle is as follows: Turn on the direct-reading spectrometer and preheat it to a stable state. Make the electrode detection head of the spectrometer touch the detection position of the aluminum ingot to ensure close contact. Then start the analysis program. Excite the sample metal atoms to emit light through a high-energy arc or spark discharge. Different elements emit light of different wavelengths. The photomultiplier tube (a special photoelectric sensor) in the direct-reading spectrometer receives the optical signal of the characteristic spectrum, converts it into a weak electrical signal through the photoelectric effect. After the electrical signal is amplified by the amplifier, it is collected and processed by a data processing system (such as a computer). Then, the intensity of the spectral line is calculated, converted into the percentage of the element content, and the mass fraction of each element is displayed on the screen and automatically compared with the preset standard. Finally, the detection result is exported to judge the detection quality.

[0039] After the detection is completed, control the electric telescopic rod 311 to contract, driving the carrier seat 313 to move upward. The carrier seat 313 then drives the slide plate 314 and the drive motor 341 to move upward. The drive motor 341 drives the detector 35 to move upward through the transmission shaft 342. The slide plate 314 moves upward until it touches the upper cavity wall of the strip frame 312. Then, through the strip frame 312, the mounting seat 32 is driven to move upward as a whole. The mounting seat 32 then drives the rotating cylinder 33 to move upward. During the continuous upward movement of the rotating cylinder 33, the downward pressure on the connecting rod 362 is gradually weakened, and the upper end of the connecting rod 362 is driven to move upward synchronously. During the upward movement of the connecting rod 362, under the reset of the reset spring 5, the arc-shaped grinding plate 37 is pushed to move towards the direction close to the axis of the rotating cylinder 33 until the arc-shaped grinding plates 37 come together and contact again, and the reset is completed.

[0040] Please refer to Figure 1 and Figure 5 In this embodiment, the position adjustment mechanism 4 includes two rotating shafts 41 respectively penetrating and rotatably connected to the front and rear wall plates of the support frame 1. Sleeve clamping units 42 are arranged at the relative ends of the two rotating shafts 41. A circular seat 43 sleeving the outer part of the front rotating shaft 41 is fixedly connected to the front end face of the support frame 1. An arc-shaped channel 44 is opened in the circular seat 43. A sliding column 45 slidably arranged in the arc-shaped channel 44 is fixedly connected to the outer part of the front rotating shaft 41 through a connecting plate. A locking plug unit 46 for limiting and locking the sliding column 45 is arranged on the circular seat 43.

[0041] Please refer to Figure 5 and Figure 6, the collet unit 42 includes a collet base 421 fixedly connected to the end of the rotating shaft 41. A U-shaped placement frame 422 is fixedly connected to the side of the collet base 421 away from the rotating shaft 41. A pressing plate 423 is jointly hinged between the left and right opposite sides of the U-shaped placement frame 422. A rectangular sleeve 424 for limiting the pressing plate 423 is slidably sleeved outside the collet base 421. Symmetrically fixed to the left and right sides at the rear of the rectangular sleeve 424 are limiting springs, and the rear ends of the limiting springs are fixedly connected to the outside of the collet base 421 through fixing blocks.

[0042] Please refer to Figure 5 , Figure 7 and Figure 8 , the locking and inserting unit 46 includes a spring telescopic rod 461, an inserting plate 462, and a C-shaped groove 463. A fixing plate is fixedly connected to the inner wall of the annular seat 43. Spring telescopic rods 461 are fixedly connected to both the left and right side end faces of the fixing plate. The ends of the spring telescopic rods 461 away from the fixing plate are fixedly connected to inserting plates 462 that slide through the annular seat 43, and the inserting plates 462 extend into the arc-shaped channel 44. C-shaped grooves 463 for cooperating with the sliding columns 45 are provided on the sides of the two inserting plates 462 away from each other. Pushing rods are fixedly connected to the front end faces of the inserting plates 462.

[0043] During detection, first manually pull the two rectangular sleeves 424 to move away from each other, so that the rectangular sleeves 424 are moved away from the outside of the pressing plate 423. Then, the pressing plate 423 can be manually toggled to rotate upward to a vertical state. Subsequently, the aluminum ingot can be placed into the U-shaped placement frame 422. Then, the pressing plate 423 is rotated in the reverse direction to fit on the surface of the aluminum ingot. Then, the rectangular sleeves 424 are released, and the reset springs 5 in the compressed state push the rectangular sleeves 424 to move back to their original positions and are sleeved on the outside of the pressing plate 423 again. The pressing plate 423 and the U-shaped placement frame 422 jointly form a collet at the end of the aluminum ingot. The sliding column 45 is initially located at the three o'clock or nine o'clock position of the annular seat 43. At this time, a corresponding inserting plate 462 drives the C-shaped groove 463 to be sleeved on the outside of the sliding column 45.

[0044] After detecting the upward end side of the aluminum ingot, manually pinch the two pushing rods to move closer to each other. The pushing rods then drive the inserting plates 462 to move, and further drive the inserting plates 462 to drive the C-shaped grooves 463 to move away from the outside of the sliding column 45. Then, manually push the collet base 421 to rotate. The collet base 421 then drives the rotating shaft 41, and the rotating shaft 41 then drives the sliding column 45 to slide in the arc-shaped channel 44 through the connecting plate until the sliding column 45 rotates 180 degrees in the arc-shaped channel 44. At this time, the aluminum ingot becomes the other side facing upward. Then, release the pinched pushing rods. The spring telescopic rods 461 reset and push the inserting plates 462 to move closer to each other towards the annular seat 43. The inserting plates 462 then drive the C-shaped grooves 463 to be sleeved on the outside of the sliding column 45 again to limit the sliding column 45 after the position is adjusted, so as to ensure that the aluminum ingot is in a stable state after the position is adjusted.

[0045] During operation, first place the aluminum ingot into the sleeve clamping unit 42, then use the locking plug unit 46 to limit the position of the aluminum ingot. Next, manually push the grinding type detection part 3 to move along the sliding part 2 to a suitable position. Subsequently, control the telescopic unit 31 to operate to drive the arc grinding plate 37 to move downward and touch the surface of the aluminum ingot. Immediately afterwards, control the rotation driving unit 34 to operate to drive the arc grinding plate 37 to rotate. At the same time, the arc grinding plate 37 moves outward and expands under the action of the expansion component 36, and the arc grinding plate 37 moves successively from the inside to the outside along the measured surface points of the aluminum ingot and rotates at the same time, so that the surface oxide layer at the measured position of the aluminum ingot can be removed by friction. Then, the detector 35 moves downward to contact and detect the surface of the aluminum ingot after the oxide layer has been removed. After detecting one side surface of the aluminum ingot, control the grinding type detection part 3 to reset. Subsequently, control the locking plug unit 46 to release the locking of the rotating shaft 41, and then the sleeve clamping unit 42 can be rotated to drive the aluminum ingot to adjust its position so that the other side faces upward. After the aluminum ingot has adjusted its position, the position of the aluminum ingot is limited again by the locking plug unit 46.
