Description

Technical Field

[0001] The present application relates to the technical field of casting component strength detection devices, and in particular to a casting component strength detection device. Background Art

[0002] Casting parts are widely used in the field of automobile manufacturing, especially the cylinder head, one of the key components in engine production and manufacturing. The working environment of the cylinder head is very harsh and needs to withstand high temperature, high pressure and complex mechanical stress. Therefore, its material strength and structural stability are crucial to the safety and service life of the car. In order to ensure the quality and performance of the cylinder head, strict strength testing must be carried out during the manufacturing process.

[0003] At present, the strength testing methods of casting parts are mainly divided into two categories: destructive and non-destructive. Destructive testing methods obtain the ultimate strength of the parts by applying external force until the parts finally fail. The most common destructive tests include tensile tests, compression tests, impact tests, etc. These methods are intuitive and easy to operate, and can more accurately evaluate the ultimate load-bearing capacity of parts. Non-destructive testing methods can analyze the internal structure of parts without damaging them, such as ultrasonic testing, X-ray testing, and eddy current testing. These methods can identify material defects and cracks in parts.

[0004] However, although the current testing methods can effectively evaluate the strength limit of components, they cannot provide information about their initial deformation before failure. In particular, key casting components such as automobile engine cylinder heads may have undergone slight plastic deformation before reaching the failure load. This early deformation may further deteriorate with changes in usage conditions, leading to fatigue damage or potential structural failure of components. If only the ultimate strength is relied upon as the testing standard, potential safety hazards caused by early deformation may be ignored. Summary of the invention

[0012] A verification piece is provided on the liquid outlet tube, and the verification piece includes a liquid display tube, a piston plate and a compression spring. The liquid display tube is fixed on the liquid outlet tube, and the liquid display tube is located between the second solenoid valve and the elastic bag. The liquid display tube is connected with the liquid outlet tube, and a visual window is provided on the liquid display tube. The piston plate is slidably arranged in the liquid display tube, the piston plate is set to be red, and the piston plate and the liquid display tube are sealed. The piston plate divides the inner cavity of the liquid display tube into two independent chambers, and the two independent chambers are respectively set as a liquid inlet chamber and a cache chamber, and the liquid inlet chamber is connected with the elastic bag; the compression spring is arranged in the cache chamber, one end of the compression spring is fixedly connected to the piston plate, and the other end of the compression spring is fixedly connected to the inner wall of the cache chamber, and the piston plate will slide in the liquid display tube due to the volume change of the elastic bag.

[0013] By adopting the above technical scheme, an elastic bag is arranged on the bottom plate, and a liquid inlet pipe and a liquid outlet pipe are arranged on the elastic bag to control the liquid inlet and liquid outlet. The diphenyl oxalate liquid is injected into the elastic bag to expand its volume. The expanded elastic bag can fit tightly with the inner cavity of the casting component. The expansion of the elastic bag adapts to the inner cavity of the casting component with different shapes, avoiding the detection blind area or uneven pressure caused by the difference in the shape of the inner cavity during detection, expanding the application range of the device, and improving the applicability of the detection device. At the same time, since the casting component is a rigid component, once the casting component is subjected to pressure and plastic deformation occurs, the casting component The volume of the inner cavity will become smaller, and the elastic bag will be squeezed so that the content inside is squeezed into the detection box. Diphenyl oxalate reacts chemically with the hydrogen peroxide solution to produce fluorescence. The set photosensitive sensor detects the fluorescence intensity. In this way, it is no longer necessary to rely on complex mechanical or visual means. The strength change of the cast parts after being compressed can be detected in real time. It can not only quickly and intuitively evaluate the deformation and strength change of the parts under pressure, but also has extremely high sensitivity and intuitiveness, ensuring the accuracy of each detection, but also reducing the tedious steps of manual operation, improving the automation level of the detection equipment, and reducing the possibility of human error.

[0014] In addition, the verification parts provided include a liquid display tube, a piston plate and a compression spring. The liquid display tube displays the flow of liquid through a visual window. The piston plate is sealed to the inner wall of the liquid display tube and can slide with the flow of liquid in the elastic bag. The casting component will deform when squeezed, and the deformation may be elastic deformation or plastic deformation. The elastic deformation may also cause the volume change of the inner cavity of the casting, causing the diphenyl oxalate in the elastic bag to be squeezed into the detection box, but the elastic deformation is reversible. When the pressure on the casting component is released, the casting component will return to its original shape. The liquid display tube is connected to the liquid outlet pipe, and the piston plate is slidably provided in the liquid display tube. When the casting is restored to its original shape, the pressure in the elastic bag is When the pressure is reduced, the piston plate will squeeze part of the diphenyl oxalate in the liquid display tube into the elastic bag, and the position of the piston plate will change. Similarly, if the casting undergoes plastic deformation, the position of the piston plate will basically not change. In summary, the position of the piston plate observed by the liquid display tube before and after the test can be used to determine whether the casting tested in the previous step has plastic deformation. When the casting parts are confirmed to have plastic deformation through the liquid display tube, the sliding distance of the piston plate in the liquid display tube is observed, which can also reflect the degree of deformation change of the casting parts when plastic deformation occurs. In addition, the compression spring provided provides an automatic reset function to ensure that the system can quickly prepare for the next operation after the detection is completed, thereby improving the detection efficiency and simplifying the operation process.

[0068] Reference Figure 7 and Figure 8 In the embodiment of the present application, the detection component 4 includes an elastic bag 41, a verification part 44, an adaptive blocking part 45, a detection box 42 and a liquid storage tank 43. The verification part 44 includes a liquid display tube 441, a piston plate 442 and a compression spring 443. The elastic bag 41 is fixed on the side of the bottom plate 21 away from the mounting frame 11. A connecting seat is fixed on the elastic bag 41. The connecting seat is penetrated on the bottom plate 21. The mounting frame 11 is provided with an avoidance groove for avoiding the connecting seat. A liquid inlet pipe 411 and a liquid outlet pipe 412 are respectively provided on the connecting seat. The liquid inlet pipe 411 and the liquid outlet pipe 412 are both connected to the elastic bag 41. A first solenoid valve 413 is provided on the liquid inlet pipe 411, and a second solenoid valve 414 is provided on the liquid outlet pipe 412. The first solenoid valve 413 and the second solenoid valve 414 are both electrically connected to the controller 12.

[0069] The liquid display tube 441 is fixed on the liquid outlet tube 412, and the liquid display tube 441 is located between the second solenoid valve 414 and the elastic bag 41, the liquid display tube 441 is connected with the liquid outlet tube 412, a visual window is provided on the liquid display tube 441, a piston plate 442 is slidably set in the liquid display tube 441, the piston plate 442 is set to be red, and the piston plate 442 and the liquid display tube 441 are sealed, the piston plate 442 divides the inner cavity of the liquid display tube 441 into two independent chambers, the two independent chambers are respectively set as a liquid inlet chamber 4411 and a cache chamber 4412, and the liquid inlet chamber 4411 is connected with the elastic bag 41; a compression spring 443 is arranged in the cache chamber 4412, one end of the compression spring 443 is fixedly connected to the piston plate 442, and the other end of the compression spring 443 is fixedly connected to the inner wall of the cache chamber 4412.

[0070] When the casting is squeezed, it will deform, and the deformation may be elastic deformation or plastic deformation. The elastic deformation will also cause the volume change of the inner cavity of the casting, causing the diphenyl oxalate in the elastic bag 41 to be squeezed into the detection box 42, but the elastic deformation is reversible. When the pressure on the casting is released, the casting will return to its original shape. The liquid display tube 441 is connected to the liquid outlet pipe 412, and the piston plate 442 is slidably set in the liquid display tube 441. In the process of the casting returning to its original shape, the pressure in the elastic bag 41 decreases, and the piston plate 442 will squeeze a part of the diphenyl oxalate in the liquid display tube 441 into the elastic bag 41, and the position of the piston plate 442 will change. Similarly, if the casting undergoes plastic deformation, the position of the piston plate 442 will basically not change. In summary, the liquid display tube 441 observes the position of the piston plate 442 before and after the detection, which can be used to determine whether the casting detected in the previous step has plastic deformation.

[0071] The adaptive blocking member 45 includes a piston cylinder 451, a piston block 452, a liquid guide tube 453, a voltage transformer plate 454, a complex spring 455 and a third solenoid valve 456. One end of the piston cylinder 451 is inclined and fixed on the liquid outlet pipe 412. The piston cylinder 451 is communicated with the liquid outlet pipe 412. The piston block 452 is slidably arranged in the piston cylinder 451. The piston block 452 separates the piston cylinder 451 to form a voltage transformer chamber 4511. The liquid guide tube 453 is arranged on one end of the piston cylinder 451. The liquid guide tube 453 is communicated with the voltage transformer chamber 4511. The voltage transformer chamber 4511 is communicated with the elastic bag 41 through the liquid guide tube 453. A retaining ring 4512 is coaxially fixed on the inner wall of the voltage transformer chamber 4511 away from the piston block 452. The voltage transformer plate 454 is slidably arranged in the voltage transformer chamber. In 4511, the transformer plate 454 and the piston cylinder 451 are sealed, and the transformer plate 454 is located between the retaining ring 4512 and the liquid guide tube 453. One end of the transformer plate 454 can abut against one end of the retaining ring 4512. The return spring 455 is arranged in the transformer chamber 4511. One end of the return spring 455 is fixedly connected to the transformer plate 454. Once the other end of the return spring 455 is fixedly connected to the piston block 452, a third solenoid valve 456 is arranged on the liquid guide tube 453, and the third solenoid valve 456 is electrically connected to the controller 12.

[0072] Since the pressures of plastic deformation caused by pressure at different positions of the casting are different, the liquid outlet pipe 412 needs to be connected to the detection box 42 all the time. However, in order to prevent the diphenyl oxalate in the elastic bag 41 from accidentally entering the detection box 42 due to unexpected factors, the liquid outlet pipe 412 and the detection box 42 must be adaptively connected, and the connecting pipe on the piston cylinder 451 is connected to the elastic bag 41. When the liquid storage tank 43 injects into the elastic bag 41, the third solenoid valve 456 is opened, and the diphenyl oxalate will also enter the transformer chamber 4511 and push the transformer plate 454. The elastic bag 41 will expand until it is completely fitted with the inner cavity of the casting, and the diphenyl oxalate will also be pushed The dynamic transformer plate 454 slides in the piston cylinder 451, one end of the transformer plate 454 abuts against the retaining ring 4512, the compound spring 455 is compressed, and the piston block 452 extends out of the piston cylinder 451 to block the liquid outlet pipe 412. At this time, the third solenoid valve 456 is closed. When the casting is not squeezed and deformed, the pressure in the liquid guide tube 453 on the side of the transformer plate 454 is the same as the pressure of the elastic bag 41, and the piston block 452 can block the liquid outlet pipe 412. Once the elastic bag 41 is squeezed, the pressure in the elastic bag 41 increases, the piston block 452 is lifted up, and the compound spring 455 is further compressed, thereby realizing the adaptive opening and closing of the liquid outlet pipe 412.

[0073] The detection box 42 and the liquid storage tank 43 are both fixed on the detection platform 1, and the detection box 42 and the liquid storage tank 43 are respectively located on both sides of the length direction of the detection platform 1. The liquid storage tank 43 is filled with liquid mixed with fluorescent dye. A pressure pump 46 is arranged on the liquid storage tank 43. The suction end of the pressure pump 46 is connected to the liquid storage tank 43, and the output end of the pressure pump 46 is connected to the end of the liquid inlet pipe 411 away from the elastic bag 41. The elastic bag 41 is connected to the liquid storage tank 43 through the liquid inlet pipe 411.

[0074] A photosensitive sensor 421 is fixedly disposed on the detection box 42 , and the photosensitive sensor 421 is electrically connected to the controller 12 . The detection box 42 is connected to the elastic bag 41 through the liquid outlet tube 412 . A hydrogen peroxide solution with a concentration of 35% is injected into the detection box 42 .

[0075] In more detail, the diphenyl oxalate in the liquid storage tank 43 is injected into the elastic bag 41 through the pressure pump 46, and the elastic bag 41 will expand until it is completely fitted with the inner cavity of the casting. Therefore, the expanded elastic bag 41 has a high pressure. At this time, if pressure is applied to the casting, once the casting begins to undergo plastic phase change, the volume of the inner cavity of the casting will change. Because pressure is applied to the casting to compress it, once plastic deformation occurs, the volume of the inner cavity of the casting will decrease, thereby causing the diphenyl oxalate in the elastic bag 41 to expand. Phenyl ester enters the detection box 42 through the liquid outlet pipe 412, and diphenyl oxalate will react chemically with the hydrogen peroxide in the detection box 42. Under the action of hydrogen peroxide, diphenyl oxalate will generate 1.2-dioxetanedione as an intermediate product. Because 1.2-dioxetanedione is very unstable, it will spontaneously decompose into carbon dioxide, releasing energy in the process. This energy will be transferred to the dye, causing it to emit light. The photosensitive sensor 421 can detect this light, so that the corresponding pressure of the casting can be detected at the moment.

[0076] The implementation principle of the casting component strength detection device of the embodiment of the present application is as follows: the casting is placed on the bottom plate 21, the bottom plate 21 is pressed to make the clamping arm 22 clamp and fix the casting, the first solenoid valve 413 is opened, the second solenoid valve 414 is closed, the pressure pump 46 injects diphenyl oxalate into the elastic bag 41, so that the elastic bag 41 expands until it is completely fitted with the inner cavity of the casting, the second solenoid valve 414 is opened, and the first solenoid valve 413 is closed; the driving member 552 drives the slide seat 143 to make the adjusting gear 551 It meshes with the active gear 331, controls the pressure motor 32 to adjust the pressure plate 34 to press the casting to the position where the strength test is required, and drives the slide 143 to mesh the active gear 331 with the driven gear 332. The pressure motor 32 drives the pressure screw 31 to slide, and the pressure plate 34 squeezes the casting. The photosensitive sensor 421 detects whether there is fluorescence in the detection box 42. At the same time, the pressure on the casting is released after the detection is completed, and the liquid display tube 441 verifies whether the casting is plastically deformed or elastically deformed.

[0077] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
