Description

Technical Field

[0001] The present invention relates to the technical field of blade density detection, in particular to a detection device for aircraft engine blades. Background Art

[0002] In the field of aero-engine manufacturing, blades are core components, and their density parameters directly affect the engine's aerodynamic performance, fatigue life, and operational stability. Accurate density detection is a key link in ensuring the reliability and safety of aero-engines. At present, the industry generally adopts a technical solution of sampling and cutting and then using a density meter for detection. This process involves multiple precise operating steps and has extremely high requirements for personnel operating specifications and instrument parameter settings. Specifically, the staff need to first place the sampled pieces of aircraft engine blades on the high-precision weighing platform of the density meter. The weighing platform is usually equipped with an electronic balance with a resolution of 0.0001g, which can accurately measure the weight of the sample in the air. Before placing the sample, the operator needs to calibrate the zero point of the balance in advance and ensure that the weighing platform is in a horizontal and stable state to avoid the measurement results being affected by instrument errors. After obtaining the weight data in the air, the staff needs to transfer the sample to a hanging basket in a special water tank. The liquid in the water tank is usually distilled water, and the water temperature needs to be controlled within the range of 20±0.5℃ to maintain the stability of the liquid density. When the sample is completely immersed in water and reaches static equilibrium, the weight data of the sample in water is read again by the density meter. Finally, based on the Archimedean principle, the density meter automatically analyzes and calculates the weight in air and the weight in water to obtain the sample density value. However, during the entire operation, the multiple manual transfers of samples not only consume a lot of time and manpower costs, but each transfer may introduce additional errors due to slight differences in operating force, angle, and speed. For example, when transferring the sample from the weighing table to the water tank basket, slight shaking of the hand may cause water droplets to adhere to the sample surface or scratches, thereby affecting the measurement results. When reading the weight in water, if the sample is not completely immersed or the basket comes into contact with the water tank wall, data deviation will occur. The combination of these human factors makes it difficult to guarantee the accuracy of the test results, and it is impossible to meet the strict quality control requirements for density parameters in the manufacturing process of aircraft engine blades. Summary of the Invention

[0003] Based on this, the purpose of the present invention is to provide a detection device for aircraft engine blades to solve the technical problems in the above-mentioned background technology.

[0004] To achieve the above-mentioned object, the present invention provides the following technical solution: a detection device for an aircraft engine blade, comprising a main body assembly, a detection assembly being provided on the top of the main body assembly, and a weighing frame being plugged into the top of a detection weighing plate of the detection assembly; The detection component further includes a weighing sensor and a circuit board. The weighing sensor is disposed at the inner bottom end of the host component through the electrically connected circuit board.

Fixing columns penetrating the detection weighing plate are fixed at the four corners of the top of the host component, and a water tank component is placed on the tops of the four groups of fixing columns above the detection weighing plate. Retractable wire mechanisms are installed on both sides inside the host component. The retractable wire mechanism includes a winding wheel and a conductive head. A wire with one end connected to the conductive head and the other end electrically connected to the integrated module is wound around the outside of the winding wheel. When the conductive head is pulled, the winding wheel is driven to release the wire, enabling the conductive head to be inserted into the conductive hole. The retractable wire mechanism further includes a support frame, a connection guiding block, and a torsion spring. Both ends between the support frame and the winding wheel are movably connected through the torsion spring, and the connection guiding block is fixed on both sides of the inner wall of the host component to guide the wire, guiding the wire after it is pulled out. The water tank component is composed of a water tank box, fixing holes, and a pick-up and placement plate. Fixing holes opened at the four corners of the bottom of the water tank box are inserted into the four groups of fixing columns to support the water tank box, and two groups of pick-up and placement plates are fixed at both ends of the water tank box to carry the water tank box.

The top mounting shell is fixed on the top of the weighing frame to protect the dual-axis motor, and the protective shell is located above the top mounting shell and is connected to the weighing frame through the plugging post.

[0007] By adopting the above technical solutions, the heat dissipation holes opened on the outer sides of the top mounting shell and the protective shell play a role in dissipating heat from the dual-axis motor.

The weighing sensor 902 is installed under the detection weighing plate 901 to accurately measure the weight of the object placed on the detection weighing plate 901 and transmit the data to the circuit board 903 and the integrated module 10; The weighing frame 4 is made of lightweight and high-strength carbon fiber material. Handles 13 are fixed on both sides, which is convenient for picking up and placing the weighing frame 4. A hanging basket 5 is movably connected at the middle position inside. Water permeable holes 501 are opened at the bottom and around the hanging basket 5 to facilitate the flow of liquid. Limit plates 502 are installed on both sides to play a role in limiting the hanging basket 5 when it rises to the initial position; Lifting mechanisms 6 are installed on both sides of the weighing frame 4.

Fixing holes 302 are opened at the four corners of the bottom and are inserted into the fixing columns 2 to achieve stable support of the water tank box 301. Take-and-place plates 303 are fixed at both ends of the water tank box 301 to facilitate handling of the water tank box 301; Equipment Preparation and Installation In a laboratory or testing site, place the main unit assembly 1 on a stable laboratory bench. By adjusting the bottom support feet, keep the main unit assembly 1 horizontal. Connect the charging head 11 to an external power supply device with a power cord to power on the equipment. Remove the water tank box 301 from the main unit assembly 1, inject distilled water into the water tank box 301 until the liquid level reaches the maximum liquid level position. Note that the water temperature is controlled within the range of 20±0.5°C. Align the fixing holes 302 at the bottom of the water tank box 301 with the fixing columns 2 at the top of the main unit assembly 1 and slowly lower it to install the water tank assembly 3 on the top of the main unit assembly 1.

[0014] Weighing Frame Installation and Zeroing Operation Align the two sides at the bottom of the weighing frame 4 with the positioning slots 905 on the detection weighing plate 901 and insert them for positioning to ensure stable installation. Press the start button on the operation panel 12 to start the main unit assembly 1. At this time, the weighing sensor 902 starts to work. The main unit assembly 1 weighs the entire weighing frame 4 through the weighing sensor 902. The display screen of the operation panel 12 shows the weighing result. Press the zero button to perform a zeroing operation on the overall weight to prepare for subsequent sample weighing.

[0015] Weighing the Sample in Air and Saving the Data The staff uses tools such as tweezers to carefully place the sample obtained from the aero-engine blade on the top of the hanging basket 5. The weighing sensor 902 measures the weight of the sample in air. The data is transmitted to the integration module 10 via the circuit board 903. After the integration module 10 analyzes and calculates, the air quality of the sample is displayed on the display screen of the operation panel 12. The staff presses the save button to save the data into the integration module 10. Then, the staff picks up the sample with tweezers again, presses the clear button to clear the current weight data, and then puts the sample back into the hanging basket 5.

[0016] Weighing the Sample in Water and Calculating the Density Press the control button on the operation panel 12 to start the dual-axis motor 602 located on both sides of the weighing frame 4. The rotation of the dual-axis motor 602 drives the reel 603 to rotate. The reel 603 winds up the towing rope 606. Under the guiding and limiting action of the limiting wheel 607, the hanging basket 5 and the sample gradually descend into the inside of the water tank box 301, ensuring that the liquid level in the water tank box 301 completely covers the top of the sample, and the hanging basket 5 and the sample are suspended in the middle position inside the water tank box 301 without contacting the bottom and side walls of the water tank box 301; Start the forward and reverse program of the dual-axis motor 602 to make the hanging basket 5 and the sample perform lifting and lowering operations inside the water tank box 301 to eliminate the bubbles generated when entering the water. The weighing sensor 902 measures the weight of the sample in water. The display screen of the operation panel 12 shows the weight of the sample, the hanging basket 5, and the connecting piece 608 as a whole in water. The staff presses the save button. The integration module 10 calculates the density of the sample according to the preset weight values of the hanging basket 5 and the connecting piece 608 in water and combines Archimedes' principle, and displays the result on the operation panel 12.

[0017] Taking out the Sample and Organizing the Equipment After the measurement is completed, press the reverse control button on the operation panel 12. The dual-axis motor 602 rotates in reverse, and the reel 603 releases the towing rope 606. The hanging basket 5 and the sample rise to the initial position. The staff uses tweezers to take out the sample from the hanging basket 5 and place it properly. Pull out the conductive head 804 of the telescopic wire mechanism 8 from the conductive hole 703. The wire is automatically wound up under the action of the torsion spring 805. Turn off the power of the main machine assembly 1, clean the distilled water in the water tank box 301, and organize and put the various components of the equipment in place to prepare for the next detection.

[0018] The working principle of the present invention is as follows: When in use, place the main machine assembly 1 on a stable tabletop to keep it stable. The support feet at its bottom can be used to make a relatively horizontal adjustment of the main machine assembly 1. Then, make the charging head 11 and an external power supply device be plugged into each other through the power cord, so that the main machine assembly 1 can be powered on and operated after being energized. At this time, the staff starts the main machine assembly 1 through the start button on the operation panel 12; First, the staff injects distilled water into the inside of the water tank box 301 to make the liquid level of the distilled water reach the maximum liquid level position of the water tank box 301. At this time, the water tank box 301 is aligned with the fixing posts 2 on the top of the main machine assembly 1 through four groups of fixing holes 302 at the bottom. Then, the water tank assembly 3 is located on the top of the main machine assembly 1, and its bottom does not contact the detection weighing plate 901 of the detection assembly 9. Then, the staff places the weighing frame 4 on the top of the detection weighing plate 901. The two sides at the bottom of the weighing frame 4 are inserted into the positioning grooves 905 on the detection weighing plate 901. Since the weighing frame 4 is composed of a hanging basket 5, two sets of lifting mechanisms 6, two sets of control modules 7 and other components as a whole, at this time, the main machine assembly 1 can weigh the whole weighing frame 4 through the weighing sensor 902, and its overall weight is displayed on the display screen of the operation panel 12. Then, the staff clears the overall weight through the clear button on the operation panel 12. After the clearing is completed, the staff uses tools such as tweezers to place the object to be measured, that is, the sample obtained from the aero-engine blade, on the top of the hanging basket 5. At this time, under the action of the weighing sensor 902, the sample is weighed in the air. At the same time, under the analysis and calculation of the integrated module 10, the air quality of the sample is displayed on the display screen of the operation panel 12 at this time. Then, the data is saved through the save button on the operation panel 12. After saving, the sample is picked up with tweezers again, and then the clear button is clicked again. After completion, the sample is placed on the hanging basket 5 again. At this time, the two-shaft motors 602 of the two sets of lifting mechanisms 6 located on both sides of the weighing frame 4 start to run. The rotation of the two-shaft motors 602 drives the winding drums 603 to rotate, so that the winding drums 603 drive the traction ropes 606 to wind up. Thus, under the limiting action of the limiting wheels 607, the hanging basket 5 with the sample is lowered. At this time, the hanging basket 5 drives the sample to gradually descend into the inside of the water tank box 301 under its own gravity, so that the liquid level inside the water tank box 301 completely covers the top of the sample, and the hanging basket 5 and the sample are suspended at the middle position inside the water tank box 301 to avoid contacting the bottom and side walls of the water tank box 301. Furthermore, when the hanging basket 5 and the sample are lowered into the inside of the water tank box 301 through the traction rope 606, at this time, the two-shaft motor 602 starts the positive and negative rotation program, and then the traction rope 606 can be wound up and lowered in a short time, so that the hanging basket 5 and the sample perform lifting and lowering operations at a certain speed inside the water tank box 301. Thus, the bubbles generated when the hanging basket 5 and the sample enter the water can be effectively eliminated, avoiding affecting the measurement structure of the sample density. Then, the load cell 902 detects the weight of the sample in water again. At this time, the display screen on the operation panel 12 shows the weight of the whole sample, the hanging basket 5 and the connecting piece 608 in water. The weights of the hanging basket 5 and the connecting piece 608 in water are preset inside the integrated module 10. At this time, the staff clicks the save button again. Then, through the calculation and analysis of the integrated module 10, subtracting the values of the weights of the hanging basket 5 and the connecting piece 608 in water, and according to Archimedes' principle, the density of the sample can be obtained; After completion, at this time, the lifting mechanism 6 runs in the reverse direction to lift the hanging basket 5 and the sample to the initial position. At this time, the staff only needs to use tools such as tweezers to clamp and take away the sample. As described above, it effectively avoids the problem that when transferring the sample from the weighing platform to the water tank hanging basket, slight shaking of the hand may cause water droplets to adhere to the surface of the sample or scratches to occur, thereby affecting the measurement result. At the same time, it avoids the problem of data deviation when reading the weight in water, if the sample is not completely immersed or the hanging basket contacts the inner wall of the water tank box 301. After effectively avoiding human factors through this equipment, the accuracy of the detection result is more accurate, which well meets the strict quality control requirements for density parameters in the manufacturing process of aeroengine blades; Furthermore, after the weighing frame 4 is installed, at this time, the conductive head 804 of the telescopic wire mechanism 8 is pulled out, and after the conductive head 804 is pulled out, it is inserted into the inside of the conductive hole 703. Then, the host component 1 can perform operations of power transmission and signal transmission on the two groups of lifting mechanisms 6 and the control module 7.
