Description

Technical Field

[0001] The present invention mainly relates to the technical field of casting crack detection, and specifically relates to a precision casting crack detection device and method. Background Art

[0002] Castings refer to metal parts with certain shapes, sizes and properties obtained by various casting methods. Castings are obtained by melting metal raw materials and injecting them into corresponding molding molds, and then cooling and solidifying them. Castings are widely used in machinery manufacturing, automobile manufacturing, shipbuilding, aerospace and other fields.

[0003] After the casting is solidified, it is necessary to use testing equipment to inspect the quality of the casting, including mechanical property testing (mainly testing the fatigue resistance and load-bearing capacity of the casting), chemical property testing (mainly testing the corrosion resistance of the casting), and uniformity testing (mainly testing the uniformity and appearance cracks of the casting). Among them, casting crack detection needs to be achieved through visual inspection equipment.

[0004] When the casting is inspected by the detection device, it needs to be placed in the middle of the processing table, and then the height of the processing table is adjusted according to the thickness of the casting so that the detection head can fit the surface of the casting. Then the casting is fixed by a fixing mechanism, and the detection head is moved above the casting for detection. The casting needs to be inspected on both sides. After the detection head has inspected one side, the fixing mechanism needs to be loosened to turn the casting over and re-fixed for inspection.

[0015] Preferably, a rotating rod is slidably connected inside one end of the sleeve rod, an elliptical transmission block is fixedly mounted on the sleeve rod, transmission plates are provided on both sides of the processing table, and the transmission block is fitted with the transmission plate.

[0016] A method for using a precision casting crack detection device, characterized in that it comprises the following steps: S1: Fix the casting, place the casting on the processing table, and then clamp the assembly, the clamping assembly clamps and fixes the casting on the processing table in the center; S2: Adjust the height. Push the support block forward through the hydraulic rod. The support block drives the detection head to move above the processing table. The lifting assembly is docked with the processing table. The height of the processing table is adjusted through the lifting assembly to lower the casting on the processing table below the detection head. S3: Start the inspection. The inspection head starts to inspect the casting. The first motor cooperates with the threaded rod to drive the inspection head to move left and right to adjust the position of the lateral inspection of the casting. The hydraulic cylinder pushes the inspection head forward to adjust the position of the inspection head for the front and back inspection of the casting. When the inspection head moves to the front, the inspection of one side of the casting is completed, and the driving components on both sides of the support block are connected with the driving components on both sides inside the base. S4: Flipping detection, start the drive assembly, the drive assembly drives the clamping assembly to rotate, the clamping assembly drives the casting to rotate and flip, and at the same time the drive assembly drives the processing table to move down first and then up to cooperate with the casting flipping. After the casting is flipped, the hydraulic cylinder drives the detection head to move backward to detect the other side of the casting. After the other side of the casting is inspected, the detection head is retracted and the clamping assembly is released to unload the casting.

[0017] Compared with the prior art, the beneficial effects of the present invention are: starting the third motor, the third motor drives the two clamping blocks to move inward relative to each other through the double-headed screw. Since the two clamping blocks move inward relative to each other synchronously, when the two clamping blocks contact the casting at the same time, the casting will be clamped and fixed in the center. In this way, when the casting is clamped and fixed by the clamping blocks, it is automatically centered without manual adjustment.

[0018] At the same time, when the detection head moves to the top of the processing table, the docking block is also inserted into the socket slot above the processing table. The cylinder drives the docking block to descend, which can drive the processing table to descend and compress the spring below. The processing table can be driven down according to the height of the casting, and the detection head can continue to move forward when it fits the upper surface of the casting and stops. This does not require manual adjustment, which is convenient to use.

[0019] When the detection head detects one side of the casting, when the detection head moves to one end of the processing table, the detection head has completed the detection of the entire surface of the casting, and the driving components on both sides of the support block are connected to the driving components on both sides of the inner wall of the base, and the driving components begin to drive the clamping block to rotate, thereby driving the casting to rotate and turn over, and in the process of turning over the casting, the driving component will drive the processing table to first descend and then rise, so that during the turning over of the casting, the processing table will synchronously perform lifting and lowering movements, and the processing table will not affect the turning over of the casting during the rotation of the casting. After the casting is turned over, the processing table rises and supports the casting, so that the casting can be automatically turned over, and there is no need to loosen the clamping and fixing of the casting before turning it over, which can improve the efficiency of turning over the casting and improve the overall efficiency of casting detection.

[0026] The specific operation process of the present invention is as follows: the casting is placed on the processing table 15, and then the casting is clamped and fixed by the clamping assembly, and then the support block 2 is driven to move forward, and the support block 2 drives the lifting assembly and the detection head 8 to move forward. When the detection head 8 moves to the top of the processing table 15, the lifting assembly is connected to the processing table 15. When the thickness of the casting is too thick, the detection head 8 presses on one side of the casting and cannot move forward. At this time, the processing table 15 is driven down by the lifting assembly. When the processing table 15 is lowered to the casting under the detection head 8, the lifting assembly is stopped. At this time, the support block 2 is driven to continue to move forward, and the detection head 8 is attached to the upper surface of the casting. The upper surface of the casting is detected by the detection head 8. When the detection head 8 moves to one side of the processing table 15, the entire surface of the casting is detected. At this time, the driving components on both sides of the support block 2 are connected to the driving components on both sides of the processing table 15. At this time, the driving components can drive the clamping components to rotate, and the clamping components will drive the casting to rotate and turn over. At the same time, the driving components will drive the processing table 15 to perform lifting and reciprocating motion, so that the processing table 15 will not affect the turning over of the casting.

[0031] Please refer to Figure 2-Figure 8 The lifting assembly includes a support plate 10, which is arranged below the support block 2. A cylinder 11 is arranged between the support plate 10 and the support block 2. A docking block 9 is fixedly installed on one side of the support plate 10. A limiting rod 16 is inserted into the support seat 3. The upper end of the limiting rod 16 is fixedly connected to the bottom of the processing table 15. A spring 17 is sleeved on the limiting rod 16. A plug-in groove 18 is opened on the processing table 15, and the docking block 9 is inserted into the plug-in groove 18.

[0032] When the support block 2 moves forward, the support block 2 drives the docking block 9 to move forward and insert into the insertion slot 18, and the cylinder 11 is started. The cylinder 11 drives the support plate 10 to move downward, and the support plate 10 drives the docking block 9 to descend. The docking block 9 drives the processing table 15 to descend. The descent of the processing table 15 will drive the limiting rod 16 to insert into the support seat 3 and compress the spring 17. At this time, the descent of the processing table 15 drives the casting to descend synchronously, and the casting stops when it descends to below the detection head 8. At this time, the detection head 8 can move forward to the top of the casting to detect the casting.

[0033] Please refer to Figure 6-Figure 8 The clamping assembly includes a third motor 19, which is fixedly mounted on one side of the support seat 3. A double-headed screw 20 is fixedly mounted on the output end of the third motor 19. The double-headed screw 20 is rotatably connected to the inside of the support seat 3. A second moving block 21 is screwed on the double-headed screw 20. A rotating rod 22 is rotatably connected to the second moving block 21. A clamping block 23 is fixedly mounted on one end of the rotating rod 22.

[0034] Start the third motor 19, the third motor 19 drives the double-headed screw 20 to rotate, and a threaded hole compatible with the double-headed screw 20 is opened on the second movable block 21. The rotation of the double-headed screw 20 drives the second movable blocks 21 on both sides to move inward relative to each other. The second movable blocks 21 on both sides pull the rotating rod 22 to drive the clamping block 23 to move inward relative to each other, and the clamping block 23 clamps and fixes the casting.

[0035] Please refer to Figure 4-Figure 8 The driving assembly includes a second motor 13, which is fixedly mounted on one side of the support block 2. The two sides of the support block 2 are rotatably connected with the plug-in rods 12, and a pulley group 14 is sleeved between the two plug-in rods 12, one side of the plug-in rod 12 is fixedly mounted on the output end of the second motor 13. The driving assembly also includes a docking rod 24, which is rotatably connected to the two sides of the inner wall of the base 1, and one end of the plug-in rod 12 is inserted into the inside of one end of the docking rod 24. The two sides of the inner wall of the base 1 are also rotatably connected with a sleeve rod 25, a bevel gear group 26 is arranged between the docking rod 24 and the sleeve rod 25, and a rotating rod 22 is slidably connected to one end of the sleeve rod 25. An elliptical transmission block 27 is fixedly mounted on the sleeve rod 25, and a transmission plate 28 is arranged on both sides of the processing table 15, and the transmission block 27 is fitted with the transmission plate 28.

[0036] When the plug-in rod 12 is plugged into one side of the docking rod 24, the second motor 13 is started, and the second motor 13 drives the plug-in rod 12 on one side to rotate. The plug-in rod 12 on one side drives the two plug-in rods 12 to rotate at the same time through the pulley group 14. The two plug-in rods 12 drive the two docking rods 24 to rotate. The two docking rods 24 drive the two sleeve rods 25 to rotate through the bevel gear group 26. The two sleeve rods 25 drive the rotating rod 22 to rotate. The rotating rod 22 always remains plugged into the sleeve rod 25. The rotation of the rotating rod 22 drives the clamping block 23 to rotate. The rotation of the clamping blocks 23 on both sides drives the clamped castings to rotate. The elliptical transmission block 27 is rotated and turned over, and the rotation of the sleeve rod 25 will drive the rotation of the elliptical transmission block 27. The elliptical transmission block 27 first pushes the transmission plate 28 downward by continuously changing the rotation radius. The transmission plate 28 drives the processing table 15 to move downward. The processing table 15 compresses the spring 17 below. Then the transmission block 27 rotates to the maximum radius and the radius begins to shorten. At this time, the spring 17 will rebound and reset, driving the processing table 15 to rise. In this way, when the casting is rotated and turned over, the processing table 15 synchronously performs a lifting and reciprocating motion to cooperate with the casting, which will not affect the rotation of the casting. When the casting is rotated and turned over, the processing table 15 rises again and is supported under the casting.

Push the support block 2 forward through the hydraulic rod 4. The support block 2 drives the detection head 8 to move above the processing table 15. The lifting assembly docks with the processing table 15. The height of the processing table 15 is adjusted through the lifting assembly. The casting on the processing table 15 is lower than the detection head 8. S3: Start the inspection. The inspection head 8 starts to inspect the casting. The first motor 5 cooperates with the threaded rod 6 to drive the inspection head 8 to move left and right to adjust the position of the lateral inspection of the casting. The hydraulic cylinder 4 pushes the inspection head 8 forward to adjust the position of the inspection head 8 for the front and rear inspection of the casting. When the inspection head 8 moves to the front, the inspection of one side of the casting is completed, and the driving components on both sides of the support block 2 are connected with the driving components on both sides inside the base 1. S4: Flipping detection, start the driving component, the driving component drives the clamping component to rotate, the clamping component drives the casting to rotate and flip, and at the same time the driving component drives the processing table 15 to move in a manner of first descending and then rising to cooperate with the flipping of the casting. After the casting is flipped, the hydraulic cylinder 4 drives the detection head 8 to move backward to detect the other side of the casting. When the other side of the casting is inspected, the detection head 8 is retracted, and the clamping component is released to unload the casting.
