Description

Technical Field

[0001] The invention relates to the field of detection technology, in particular to an alloy casting internal defect and material uniformity detection device. Background Art

[0002] With the rapid development of industrial technology, the quality requirements for alloy castings are becoming increasingly stringent. In the production and manufacturing process of alloy castings, internal defects and material uniformity directly affect the performance and service life of alloy castings. Although relatively advanced detection technologies such as ultrasonic flaw detection and CT flaw detection are available, they still have many shortcomings.

[0003] Among them, although the detection technology based on the ultrasonic principle can detect the defects and material uniformity inside the alloy casting to a certain extent, in order to ensure the detection accuracy during the working process, it is often necessary to coat the surface of the alloy casting with a coupling agent. For example, the patents "CN111272884A A metal casting ultrasonic detection device", "CN221056318U A casting surface defect detection device", and "CN117741090A A gearbox precision casting quality defect detection method" all disclose a defect detection technology based on the ultrasonic principle. However, after each detection work, the staff needs to clean the coupling agent on the surface of the workpiece before taking the workpiece away, which is not conducive to improving the detection efficiency. In addition, the existing detection equipment usually has a coating mechanism to evenly coat the coupling agent on the surface of the workpiece, but the existing coating mechanism often needs to be manually cleaned after the work is completed. However, this process is not only labor-intensive, but also easily leads to untimely cleaning, causing the coupling agent to dry on the coating mechanism, thereby affecting the next use effect of the coating mechanism. Summary of the invention

[0004] The purpose of the present invention is to provide an alloy casting internal defect and material uniformity detection device to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an alloy casting internal defect and material uniformity detection device, the detection device comprises a fuselage, a detection chamber is provided at the inner side end of the fuselage, a door is provided at the side end of the detection chamber, a first mounting seat is provided at the inner upper end of the detection chamber, a workbench is provided at the inner lower end of the detection chamber, a clamping assembly is provided above the workbench, and alloy castings of different shapes are fixed by the clamping assembly, a second mounting seat is provided at the middle position of the workbench, a second lifting mechanism is provided inside the workbench, and the lifting of the workbench is controlled by the second lifting mechanism, a detection mechanism is provided on the second mounting seat, and the detection mechanism is connected to the second mounting seat through a second movable module, a first lifting mechanism is provided below the first mounting seat, and the first lifting mechanism is connected to the first mounting seat through the first movable module, and the lower part of the first lifting mechanism A coating mechanism is provided. The present invention is provided with a first movable module and a second movable module. When the alloy casting is fixed by the clamping assembly, the coating mechanism can freely move longitudinally and laterally above the alloy casting through the first movable module, and the detection mechanism can freely move longitudinally and laterally below the alloy casting through the second movable module (the functions realized by the first movable module and the second movable module belong to conventional technical means in this field, and the specific structure is not described). The present invention coats the ultrasonic coupling agent to the surface of the alloy casting through the coating mechanism, and detects the internal defects and material uniformity of the alloy casting through the detection mechanism. Finally, compared with the current detection equipment, the coating mechanism in the present invention has an automatic cleaning function, so as to avoid the next detection work interval being too long, so that the ultrasonic coupling agent remaining at the lower end of the coating mechanism solidifies, thereby affecting the subsequent detection work of the alloy casting.

[0006] Furthermore, the detection mechanism includes an ultrasonic probe, a waste box and a discharge seat, the ultrasonic probe is arranged at the upper middle position of the waste box, the discharge seat is arranged at the side end of the ultrasonic probe, the discharge seat and the ultrasonic probe are aligned with each other, a cleaning plate and a support frame are arranged in the discharge seat, the cleaning plate is arranged at the inner upper end of the support frame, and the support frame is connected to the discharge seat through a linear motor. When the alloy casting is cylindrical, the staff fixes the alloy casting through a clamping assembly, and then uses a first lifting mechanism and a second lifting mechanism to make the coating mechanism and the ultrasonic probe close to the surface of the alloy casting, and then uses a linear motor to make the cleaning plate contact with the alloy casting, and finally drives the alloy casting to rotate through the clamping assembly, so that the area to be detected of the alloy casting passes through the coating mechanism, the ultrasonic probe and the cleaning plate in turn. The present invention coats the ultrasonic coupling agent to the surface of the area to be detected of the alloy casting through the coating mechanism, detects the internal defects and material uniformity of the alloy casting through the ultrasonic probe, and removes the ultrasonic coupling agent from the detected area on the surface of the alloy casting through the cleaning plate; when the alloy casting is rectangular, the present invention The invention firstly uses the first lifting mechanism and the first moving module to make the coating mechanism coat the ultrasonic coupling agent on one surface of the alloy casting. When the coating is completed, the alloy casting is driven to rotate by the clamping assembly until the side of the alloy casting coated with the ultrasonic coupling agent is close to the detection mechanism. At this time, the second lifting mechanism and the second moving module are used to make the ultrasonic probe detect the alloy casting coated with the ultrasonic coupling agent. Finally, during the process of the ultrasonic probe detecting the alloy casting, on the one hand, the cleaning plate will simultaneously remove the ultrasonic coupling agent in the detected area of ​​the alloy casting surface to avoid the trouble of subsequent cleaning. On the other hand, the coating mechanism will simultaneously coat the ultrasonic coupling agent on the other surface of the alloy casting to facilitate the ultrasonic probe to perform defect detection on the alloy casting from the other side of the alloy casting, thereby preventing the alloy casting from being too thick and affecting the detection accuracy. Compared with the current detection equipment, the present invention can detect defects on the alloy casting while removing the ultrasonic coupling agent in the detection area, thereby ensuring that after the alloy casting detection is completed, the staff can directly take the alloy casting away, thereby improving the detection efficiency.

[0007] Furthermore, the clamping assembly includes a clamping seat, which is provided with two groups. The two groups of clamping seats are relatively arranged at the two ends above the workbench, and a group of rotating motors are arranged inside each group of clamping seats. A group of cylinders are arranged on the side where the two groups of rotating motors are close to each other, and each group of cylinders is connected to a group of rotating motors through a group of turntables. A group of clamping disks are arranged at the working ends of the two groups of cylinders. The present invention clamps the alloy casting by two groups of cylinders and two groups of clamping disks, and drives the alloy casting to rotate by a rotating motor, so as to control the direction of the area to be inspected of the alloy casting.

[0008] Furthermore, a slide groove is provided in the support frame, and a piezoelectric sheet and a compression spring are provided in the slide groove, one end of the compression spring is connected to the cleaning plate, and the other end of the compression spring is connected to the piezoelectric sheet. Before detecting the alloy casting, the staff can first turn on the linear motor to make the cleaning plate contact with the alloy casting, so as to facilitate the subsequent cleaning of the ultrasonic coupling agent on the surface of the alloy casting by the cleaning plate. After the cleaning plate contacts with the alloy casting, if the cleaning plate continues to move upward, the compression spring will be deformed, and the piezoelectric sheet will generate a group of electrical signals at this time. Through this group of electrical signals, the staff can timely judge the contact status of the cleaning plate and the alloy casting, and then turn off the linear motor. Through the above technical scheme, it is possible to effectively avoid the cleaning plate from exerting a large pressure on the alloy casting, and prevent mechanical damage to the surface of the alloy casting.

[0009] Furthermore, a third electromagnet is provided at the lower end of the interior of the support frame, and one end of the cleaning plate close to the third electromagnet is made of ferromagnetic material.

By controlling the opening frequency of the third electromagnet, the cleaning plate can be made to vibrate back and forth in the support frame, thereby reducing the probability of the ultrasonic coupling agent remaining on the cleaning plate due to viscosity and other reasons, ensuring that the cleaning plate can still work normally and stably during the subsequent detection of alloy castings.

When the coating mechanism in the present invention is working, the area to be inspected of the alloy casting will move along the coating head and the scraper, and at the same time, the ultrasonic coupling agent will flow into the coating head along the hose, the fixed tube, and the second movable tube, and then flow out from the outlet end of the coating head. Finally, the cleaning motor will drive the second movable tube and the coating mechanism to rotate through the first gear and the second gear, and the ultrasonic coupling agent will be evenly coated on the surface of the alloy casting through the coating mechanism. The scraper is used to ensure that the thickness of the ultrasonic coupling agent is always within the standard range to avoid affecting the detection accuracy.

The end of the coating head away from the second electromagnet is elastic, and the end of the coating head close to the second electromagnet is embedded with a first magnetic block.

[0012] Furthermore, the coating mechanism also includes a cleaning component, which is arranged between the coating head and the scraper. The coating head and the second movable tube in the present invention are connected by a key and a keyway, thereby allowing the coating head to have a certain axial movement ability on the second movable tube, but limiting the coating head from rotating relative to the second movable tube. When the coating mechanism in the present invention is working, the second electromagnet always generates a set of magnetic fields that repel the coating head, so that the coating head can evenly coat the ultrasonic coupling agent on the surface of the alloy casting. When the coating mechanism is not working, the second electromagnet will generate a set of magnetic fields that attract the coating head, thereby making the lower surface of the coating head flush with the lower surface of the fixed seat (the second electromagnet does not contact the coating head). At this time, the staff can turn on the cleaning component and use the cleaning component to clean the ultrasonic coupling agent intercepted by the scraper and the coupling agent remaining at the outlet of the coating head, thereby avoiding the solidification of the ultrasonic coupling agent under the coating mechanism and affecting subsequent detection work.

State, when the alloy casting inspection is completed and the lower surface of the coating head is flush with the lower surface of the fixed seat, the staff can first turn on the first electromagnet. At this time, the first electromagnet will generate a set of magnetic fields that attract the first gear, and the first gear and the first movable tube are magnetically fixed together through the first electromagnet. On the other hand, the first electromagnet will generate a set of magnetic fields that repel the telescopic rod, so that the telescopic rod and the cleaning frame move downward. When the cleaning frame extends out of the lower end of the fixed seat, the staff can turn on the cleaning motor, and drive the first gear and the first movable tube cleaning frame to rotate through the cleaning motor (at this time, the coating head will rotate in the fixed seat), and the ultrasonic coupling agent retained by the scraper and the coupling agent remaining at the outlet of the coating head are cleaned through the cleaning frame.

The present invention is provided with a first movable module and a second movable module. When the alloy casting is fixed by the clamping assembly, the coating mechanism 3 can freely move longitudinally and laterally above the alloy casting through the first movable module, and the detection mechanism 6 can freely move longitudinally and laterally below the alloy casting through the second movable module (the functions realized by the first movable module and the second movable module belong to conventional technical means in this field, and the specific structure is not described). The present invention coats the ultrasonic coupling agent to the surface of the alloy casting through the coating mechanism 3, and detects the internal defects and material uniformity of the alloy casting through the detection mechanism 6. Finally, compared with the current detection equipment, the coating mechanism 3 in the present invention has an automatic cleaning function, so as to avoid the next detection work interval being too long, so that the ultrasonic coupling agent remaining at the lower end of the coating mechanism 3 solidifies, thereby affecting the subsequent detection work of the alloy casting.

[0020] like Figure 3-Figure 5 As shown, the detection mechanism 6 includes an ultrasonic probe 61, a waste box 62 and a discharge seat 64. The ultrasonic probe 61 is arranged at the upper middle position of the waste box 62, and the discharge seat 64 is arranged at the side end of the ultrasonic probe 61. The discharge seat 64 and the ultrasonic probe 61 are aligned with each other. A cleaning plate 63 and a support frame 65 are arranged in the discharge seat 64. The cleaning plate 63 is arranged at the inner upper end of the support frame 65, and the support frame 65 is connected to the discharge seat 64 through a linear motor 641.

[0021] like Figure 2-Figure 3As shown, the clamping assembly includes a clamping seat 4, which is provided with two groups. The two groups of clamping seats 4 are relatively arranged at the two ends above the workbench 5, and a group of rotating motors 41 are arranged inside each group of clamping seats 4. A group of cylinders 43 are arranged on the side where the two groups of rotating motors 41 are close to each other, and each group of cylinders 43 is connected to a group of rotating motors 41 through a group of turntables 42. A group of clamping disks 44 are arranged at the working ends of the two groups of cylinders 43. The alloy castings of different shapes are fixed by the clamping assembly, and the direction of the area to be detected of the alloy castings is controlled at the same time.

Then the staff can turn on the linear motor 641 to make the cleaning plate 63 contact the alloy casting. Finally, the rotating motor 41 is turned on to drive the alloy casting to rotate so that the area to be detected of the alloy casting passes through the coating mechanism 3, the ultrasonic probe 61 and the cleaning plate 63 in sequence. The present invention coats the ultrasonic coupling agent to the surface of the area to be detected of the alloy casting through the coating mechanism 3, detects the internal defects and material uniformity of the alloy casting through the ultrasonic probe 61, and removes the ultrasonic coupling agent from the detected area on the surface of the alloy casting through the cleaning plate 63. When the alloy casting is rectangular, the staff can first turn on the first lifting mechanism 21 and the first moving module after clamping the alloy casting through two groups of cylinders 43 and two groups of clamping plates 44, so that the coating mechanism 3 first coats the ultrasonic coupling agent on one surface of the alloy casting. When the coating is completed, the staff can The alloy casting is driven to rotate by the rotating motor 41 until the side of the alloy casting coated with the ultrasonic coupling agent is close to the detection mechanism 6. At this time, the staff can open the second lifting mechanism 52 and the second movable module to enable the ultrasonic probe 61 to detect the alloy casting coated with the ultrasonic coupling agent. Finally, during the process of the ultrasonic probe 61 detecting the alloy casting, on the one hand, the cleaning plate 63 will simultaneously remove the ultrasonic coupling agent in the detected area of ​​the alloy casting surface to avoid the trouble of subsequent cleaning. On the other hand, the coating mechanism 3 will simultaneously coat the other surface of the alloy casting with ultrasonic coupling agent to facilitate the ultrasonic probe 61 to perform defect detection on the alloy casting from the other side of the alloy casting, thereby preventing the alloy casting from being too thick and affecting the detection accuracy. Compared with the current detection equipment, the present invention can perform defect detection on the alloy casting while removing the ultrasonic coupling agent in the detection area, thereby ensuring that the staff can directly take the alloy casting away after the alloy casting detection is completed, thereby improving the detection efficiency.

In the present invention, before detecting the alloy casting, the staff can first turn on the linear motor 641 to make the cleaning plate 63 contact with the alloy casting, so as to facilitate the subsequent cleaning of the ultrasonic coupling agent on the surface of the alloy casting by the cleaning plate 63. When the cleaning plate 63 contacts the alloy casting, if the cleaning plate 63 continues to move upward, the compression spring will be deformed, and the piezoelectric sheet 651 will generate a group of electrical signals at this time. Through this group of electrical signals, the staff can timely judge the contact status of the cleaning plate 63 and the alloy casting, and then turn off the linear motor 641. Through the above technical scheme, it is possible to effectively avoid the cleaning plate 63 from exerting a large pressure on the alloy casting, thereby preventing mechanical damage to the surface of the alloy casting.

After the detection work of the present invention is completed, the staff can intermittently turn on the third electromagnet 652. When the third electromagnet 652 is turned on, the cleaning plate 63 will move down under the action of the magnetic field. When the third electromagnet 652 is turned off, the cleaning plate 63 will move up under the action of the compression spring. By controlling the opening frequency of the third electromagnet 652, the cleaning plate 63 can be made to vibrate back and forth in the support frame 65, thereby reducing the probability of the ultrasonic coupling agent remaining on the cleaning plate 63 due to viscosity and other reasons, ensuring that the cleaning plate 63 can still work normally and stably during the subsequent detection of the alloy castings.

[0025] like Figure 7-Figure 8As shown, the coating mechanism 3 includes a fixed seat 31, a coating head 32 and a scraper 33.

At the same time, the ultrasonic coupling agent flows into the coating head 32 along the hose, the fixed tube 36, and the second movable tube 37, and then flows out from the outlet end of the coating head 32. Finally, the cleaning motor 35 drives the second movable tube 37 and the coating mechanism 3 to rotate through the first gear 342 and the second gear 371, and the ultrasonic coupling agent is evenly coated on the surface of the alloy casting through the coating mechanism 3. The scraper 33 ensures that the thickness of the ultrasonic coupling agent is always within the standard range to avoid affecting the detection accuracy.

The end of the coating head 32 away from the second electromagnet 38 is elastic, and the end of the coating head 32 close to the second electromagnet 38 is inlaid with a first magnetic block.

[0027] like Figure 7-Figure 9 As shown, the coating mechanism 3 further includes a cleaning component, which is arranged between the coating head 32 and the scraper 33.

[0028] In the present invention, the coating head 32 is connected to the second movable tube 37 by a key and a keyway, thereby allowing the coating head 32 to have a certain axial movement ability on the second movable tube 37, but limiting the coating head 32 from rotating relative to the second movable tube 37. When the coating mechanism 3 in the present invention is working, the second electromagnet 38 always generates a set of magnetic fields that repel the coating head 32, so as to facilitate the coating head 32 to evenly coat the ultrasonic coupling agent on the surface of the alloy casting. When the coating mechanism 3 is not working, the second electromagnet 38 will generate a set of magnetic fields that attract the coating head 32, thereby making the lower surface of the coating head 32 flush with the lower surface of the fixing seat 31 (the second electromagnet 38 does not contact the coating head 32). At this time, the staff can turn on the cleaning component and use the cleaning component to clean the ultrasonic coupling agent intercepted by the scraper 33 and the coupling agent remaining at the outlet end of the coating head 32, thereby avoiding the ultrasonic coupling agent solidification phenomenon under the coating mechanism 3, which affects the subsequent detection work.

At this time, the first electromagnet 3411 will generate a set of magnetic fields that attract the first gear 342, and the first gear 342 and the first movable tube 341 are magnetically fixed together through the first electromagnet 3411. On the other hand, the first electromagnet 3411 will generate a set of magnetic fields that repel the telescopic rod 3412, so that the telescopic rod 3412 and the cleaning frame 34 move downward. When the cleaning frame 34 extends out of the lower end of the fixing seat 31, the staff can turn on the cleaning motor 35, and drive the first gear 342, the first movable tube 341 and the cleaning frame 34 to rotate (at this time, the coating head 32 will rotate in the fixing seat 31), and the ultrasonic coupling agent intercepted by the scraper 33 and the coupling agent remaining at the outlet end of the coating head 32 are cleaned through the cleaning frame 34.

[0030] like Figure 7-Figure 9As shown, a group of cleaning cotton is provided at both ends of the cleaning frame 34, and the cleaning cotton is detachably connected to the cleaning frame 34. Through the above technical solution, the present invention can replace new cleaning cotton at any time as needed.

[0031] The working principle of the present invention is as follows: when the alloy casting is cylindrical, the staff first clamps the alloy casting by two groups of cylinders 43 and two groups of clamping plates 44, and then starts the first lifting mechanism 21 and the second lifting mechanism 52, so that the coating mechanism 3 and the ultrasonic probe 61 are close to the surface of the alloy casting, and then the cleaning plate 63 is brought into contact with the alloy casting by the linear motor 641, and finally the alloy casting is driven to rotate by the rotary motor 41, so that the area to be tested of the alloy casting passes through the coating mechanism 3, the ultrasonic probe 61 and the cleaning plate 63 in sequence, and the ultrasonic probe 61 is passed through the coating mechanism 3. The ultrasonic coupling agent is coated on the surface of the alloy casting in the area to be tested, and the internal defects and material uniformity of the alloy casting are tested by the ultrasonic probe 61, and the ultrasonic coupling agent in the tested area of ​​the alloy casting surface is removed by the cleaning plate 63; when the alloy casting is rectangular, the staff clamps the alloy casting by two sets of cylinders 43 and two sets of clamping plates 44, and then starts the first lifting mechanism 21 and the first moving module, so that the coating mechanism 3 first coats the ultrasonic coupling agent on one surface of the alloy casting, and when the coating is completed, the alloy casting is driven to rotate by the rotating motor 41. The ultrasonic coupling agent is rotated until the side of the alloy casting coated with the ultrasonic coupling agent is close to the detection mechanism 6. At this time, the second lifting mechanism 52 and the second moving module are turned on to enable the ultrasonic probe 61 to detect the alloy casting coated with the ultrasonic coupling agent. Finally, during the process of the ultrasonic probe 61 detecting the alloy casting, on the one hand, the cleaning plate 63 will synchronously remove the ultrasonic coupling agent in the detected area on the surface of the alloy casting to avoid the trouble of subsequent cleaning. On the other hand, the coating mechanism 3 will synchronously coat the other surface of the alloy casting with the ultrasonic coupling agent. After the detection work of the present invention is completed, the staff can first intermittently turn on the third electromagnet 652 to make the cleaning plate 63 reciprocate in the support frame 65, thereby reducing the probability of the ultrasonic coupling agent remaining on the cleaning plate 63 due to viscosity and other reasons. Finally, the cleaning component in the coating mechanism 3 is turned on to clean the ultrasonic coupling agent intercepted on the scraper 33 and the coupling agent remaining at the outlet end of the coating head 32, so as to avoid the next detection work interval being too long, so that the ultrasonic coupling agent remaining at the lower end of the coating mechanism 3 solidifies, thereby affecting the subsequent detection work of the alloy casting.
