Description

Technical Field

[0001] The invention belongs to the technical field of aircraft assembly detection, and relates to an intelligent detection device for aircraft assembly hole making tool specification recognition. Background Art

[0002] The assembly of aviation products mainly uses fasteners to connect and fix parts. Holes are processed on aircraft parts and components according to the design requirements of the aircraft manufacturing process. The hole sizes processed by operators must be accurate and there must be no aperture deviation, otherwise the fasteners cannot be assembled, resulting in the scrapping of parts. Therefore, during the aircraft hole processing, operators must choose the size specifications of the tool to avoid product quality problems.

[0003] At present, the hole-making process in the production workshop will apply a variety of hole-making tools, including twist drills, deep hole drills, reaming drills, score drills, reamers, etc. The specifications of these tools are marked with the diameter and tolerance of the processed hole. Usually, the tool specifications are marked on the tool handle or on the outer packaging. The operator identifies the model and specifications of the tool through the specification markings. However, during the production and use process, it will be affected by various unfavorable factors, such as wear of the tool handle, damage to the packaging, or label shedding. At this time, the tool specifications cannot be accurately judged by the naked eye. The tool specifications can only be judged by measuring the outer diameter with general measuring tools such as vernier calipers. This method has low measurement efficiency and is greatly affected by human factors. There are uncertainties, such as reading errors and improper use of tools. Therefore, in the process of part processing and hole making, manual judgment of tool specifications may result in the wrong selection of tool specifications, which will cause the holes of parts and components to be out of tolerance, and ultimately cause huge economic losses.

[0004] In order to prevent operators from using the wrong tool model and specifications when performing hole processing on aircraft parts and components, and no longer use human eyes to judge tool specifications as the main detection method, there is an urgent need for an intelligent detection device for aircraft hole-making tool identification to solve various objective factors that are not conducive to judgment, improve the accuracy of tool identification and the efficiency of operators, and avoid scrapping parts. Summary of the invention

[0005] The present invention aims to provide an intelligent detection device for the specifications of hole-making tools for aircraft parts and components for on-site operators, so as to solve the problems in the above technical background.

[0006] The technical problem solved by the present invention is achieved by adopting the following technical solutions:

[0007] The intelligent detection device for identifying the specifications of aircraft assembly hole-making tools is used to realize the accurate and rapid screening of the specifications of aircraft hole-making tools, and avoid economic losses caused by operators misusing tool specifications. According to the shape characteristics of the tool, a two-way clamping structure is designed. After the tool is placed in the test area, the tool is fixed in the X and Y axis directions through a spring clamping mechanism, providing accurate measurement conditions for sensor measurement. At the same time, the detection device uses a high-precision displacement sensor with an intelligent control module for measurement. According to the different outer diameter values ​​of the tool, it can realize intelligent detection of tools of various specifications. Since each operator is equipped with multiple tools, the device can set multiple detection channels. The operator can randomly put tools of various specifications into each detection channel. When using the tool, just press the power switch and reset button of the device, and the display will automatically display the tool specification values ​​of each channel. The operator does not need to identify it with the naked eye. The intelligent detection device can improve the recognition accuracy and use efficiency of the tool, get rid of the objective factors that affect the judgment, and avoid the operator from misusing the tool specifications in the hole-making process. Cause unnecessary economic losses and meet the product process production requirements.

[0008] Aircraft assembly hole making tool specification identification intelligent detection device, such as the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 and attached Figure 5 As shown, it includes a fixed bracket, a shell, a clamping slider, a measuring support, an M3 countersunk screw, a fixed stud, a linkage bracket, a cylindrical wrench, a movable limit stud, a U-shaped limit support, an M4 fixed bolt, a displacement sensor, a sensor nut, an X-axis clamp, an M2.5 screw, a Y-axis clamp, a spring, a limit nut, an M2 countersunk screw, a top cover, a control box top cover, a power button, a display screen, a reset button, a control box shell, a power module, a control module, a step-down module and other components. Among them, the fixed bracket, the shell, the clamping slider, the measuring support, the M3 countersunk screw, the fixed stud, the linkage bracket, the cylindrical wrench, the movable limit stud, the U-shaped limit support, the M4 fixed bolt, the sensor nut, the X-axis clamp, the M2.5 screw, the Y-axis clamp, the spring, the limit nut, the M2 countersunk screw, the top cover, the control box top cover and the control box shell constitute the structural part of the tool specification detection device. The displacement sensor, power button, display screen, reset button, power module, control module and voltage reduction module constitute the electronic control part of the detection device.

[0009] The housing, top cover, control box top cover and control box housing in the structure are made of PLA material through 3D printing, and other components are made of metal. The housing is used to install and fix various measuring components. The measuring support is fixed to the housing with four M3 countersunk screws to fix the tool with the clamping mechanism in the X-axis and Y-axis directions. Figure 6As shown in the figure, the tool insertion area is the matching area of ​​the measuring support and the X and Y axis clamping mechanism. The fixed support is connected and fixed to the housing by two M4 fixing bolts, and is used to support the reverse force of the clamping mechanism in the X-axis direction. The X-axis clamping mechanism is mainly composed of a clamping slider, two fixed studs, a clamping piece and a spring, wherein the outer diameter of the fixed stud is 5mm, and the fixed support and the measuring support are respectively provided with two φ5mm cylindrical grooves. One side of the two fixed studs is inserted into the cylindrical groove of the fixed support, and the other side is inserted into the cylindrical groove of the measuring support. The two fixed studs are in a fixed and parallel state. The clamping slider has two φ5mm circular through holes, which can pass through the two fixed studs and be installed between the fixed support and the measuring support. The inner diameter of the spring is φ5.1mm, which can be sleeved on the outer surface of the two φ5mm fixed studs. One end of the spring contacts the fixed support, and the other end contacts the clamping slider. The clamping slider can slide on the fixed studs in the X-axis direction with the help of the spring. The X-axis clamp is fixed to the clamping slide by two M2.5 screws, and can slide synchronously with the clamping slide for clamping the tool in the X-axis direction. The Y-axis clamping mechanism is mainly composed of a movable limit stud, a U-shaped limit support, an M4 fixing bolt, a Y-axis clamp, a spring, and a limit nut. One side of the Y-axis clamp is used to fit and fix the tool, and the other side is provided with two φ5mm internal threaded holes. The movable limit stud has φ5mm threads at both ends, and one end of the two movable limit studs is screwed into the internal threaded holes of the Y-axis clamp for fixing. The U-shaped limit support is fixed to the housing by two M4 fixing bolts, which is provided with two φ5.1mm through holes. Similarly, two φ5.1mm through holes are also opened on the side wall of the housing. Therefore, the other end of the movable limit stud can pass through the through holes of the U-shaped limit support and the housing at the same time. Finally, two limit nuts are installed at the other end of the movable limit stud thread for limiting and fixing the Y-axis clamping mechanism. The spring is also sleeved on the two movable limit studs and installed between the U-shaped limit support and the Y-axis clamp. Due to the force of the spring, the Y-axis clamp can press the tool during measurement. A through hole is set in the middle part of the U-shaped limit support for installing the displacement sensor. The displacement sensor passes through the U-shaped limit support and is fixed with a sensor nut. The sensor has a reset spring inside to realize the extension and retraction of the measuring head. At the same time, the sensor head contacts the end face of the Y-axis clamp. Therefore, the movement of the Y-axis clamp will drive the displacement sensor head to generate displacement, realizing the displacement electrical signal collection of the sensor. The linkage bracket is used to connect the X-axis clamp and the Y-axis clamp. The lower end of the linkage bracket is inserted into the square slide groove at the upper end of the X-axis clamp and the Y-axis clamp. When the linkage bracket moves in the 45° direction, it can drive the X-axis clamp and the Y-axis clamp to move in the X-axis and Y-axis directions respectively. The upper end of the linkage bracket has an internal thread groove, and the cylindrical wrench has an external thread, which can be screwed and fixed on the linkage bracket.The top cover is provided with an oblong hole slot. The operator moves the cylindrical wrench along the oblong hole slot, inserts the tool from the tool insertion port, and then loosens the cylindrical wrench. Due to the reverse force of the spring, the X-axis clamp and the Y-axis clamp are automatically clamped, so that the tool position is fixed, providing accurate measurement conditions for the sensor. The top cover is fixed to the housing by four M2 countersunk screws. The installation of the above-mentioned structural parts can store and detect a specification of tool to form a single-channel detection device. Since each operator is equipped with multiple specifications of tools, a multi-channel tool detection device is designed, such as. Figure 8 As shown, the device can store and detect five types of tool specifications. After completing the operation process, the operator randomly inserts the tool into any detection channel for storage. When the tool is used next time, the control system will automatically detect and display the tool specification value of each detection channel, which is convenient for the operator to use and avoid the misuse of the tool.

[0010] The control box shell is used to install the modules of the electronic control system, and is assembled through four M2 countersunk screws and the top cover of the control box. The displacement sensor in the electronic control part adopts a high-precision electromagnetic distance sensor, with a measuring stroke of 5.00mm and a measuring accuracy of up to 0.01mm, which meets the detection requirements. When the displacement sensor head moves during measurement, it can output the corresponding analog voltage signal, and transmit it to the control module inside the control box through a cable. The control module uses the atmega328P system board, which is the main module of the control system. It can communicate with each module and issue corresponding control instructions. The control module can collect the analog voltage signal of the displacement sensor, process the received electrical signal through the 10-bit AD analog-to-digital converter of the atmega328P chip itself, calculate the telescopic displacement of the displacement sensor through the program, and finally convert the outer diameter value of the tool. The power module uses a 9V rechargeable lithium battery, and converts the 9V DC voltage into 5V through the step-down module. The 5V DC voltage can be used to power the displacement sensor, display screen and control module. The display screen uses a 0.96-inch OLED LCD screen, which is installed on the top cover and is also connected to the control module through a cable. After the displacement sensor measures, the control module drives the display screen to display the tool outer diameter value. The power button uses a metal self-locking switch, which is installed on the top cover of the control box through a matching nut. It is used to control the opening and closing of the system. When the power button is turned on, all modules are powered on at the same time to prepare for measurement. The reset button uses a metal self-reset button, which is used to restart and refresh the system program, and can realize the detection and update of the tool outer diameter value.

[0011] The method of using the intelligent detection device for identifying the specifications of aircraft assembly hole making tools is as follows:

[0012] Step 1: After the operator completes the corresponding operation process with the tool, clean the metal chips on the surface of the tool to ensure that the tool is clean and intact;

[0013] Step 2: The operator moves the cylindrical wrench along the long round hole slide groove of the top cover to open the X-axis clamp and the Y-axis clamp, and then inserts the tool into the detection area and releases the cylindrical wrench. The X-axis clamp and the Y-axis clamp will automatically clamp the tool to keep the tool position fixed;

[0014] Step 3: Follow the steps in step 2 and randomly insert tools of other specifications into the remaining four detection channels;

[0015] Step 4: The next time the operator uses the tool to perform hole processing, turn on the power button, and the control module will automatically calculate the tool outer diameter value in each channel according to the displacement of the displacement sensor in each channel, and display the tool outer diameter value on the display screen, for example, "Channel 1: 5.1mm, Channel 2: 8.1mm, Channel 3: 4.1mm, Channel 4: 6.1mm, Channel 5: 3.1mm". The operator can select the tool of the corresponding specification according to the prompts on the display screen;

[0016] Step 5: During the implementation of step 4, if the tool needs to be reinserted, follow step 2 and then press the reset button. The display screen will update the tool outer diameter value of each channel in real time.

[0017] Step 6: After completing the tool picking, the operator turns off the power button and then continues to perform the operations of steps 1 and 2.

[0018] Beneficial effects of the present invention:

[0019] The present invention has a simple structure and is easy to operate. It can store tools and detect tool outer diameter values. After completing the operation process, the operator can randomly place tools of various specifications into the channels of the detection device for storage. When using them next time, the operator only needs to turn on the power button, and the display screens of each channel will automatically display the tool specification values ​​in each channel in real time, solving various objective factors that are not conducive to determining tool specifications, avoiding manual errors in determination, and improving the accuracy of tool identification and the efficiency of operators.

[0020] During the product production process, by adopting the above-mentioned aircraft assembly hole-making tool specification intelligent detection device, the operator's tool usage method is improved, the tool identification accuracy is improved, the operator's labor intensity is reduced, the upgrade and transformation from traditional manual to intelligent detection is realized, and the economic losses caused by the wrong use of tools in the hole-making process are avoided.

[0032] The housing 2, top cover 20, control box top cover 21 and control box housing 25 in the structural part are made of PLA material through 3D printing, and other components are made of metal. The housing 2 is used to install and fix various measuring components. The measuring support 4 is fixed to the housing 2 by four M3 countersunk screws 5, which is used to cooperate with the clamping mechanism in the X-axis and Y-axis directions to fix the tool. Figure 6As shown, the tool insertion area in the figure is the matching area of ​​the measuring support 4 and the X and Y axis clamping mechanism. The fixed bracket 1 is connected and fixed to the housing 2 by two M4 fixing bolts 11, and is used to support the reverse force of the clamping mechanism in the X-axis direction. The X-axis clamping mechanism is mainly composed of a clamping slider 3, two fixing studs 6, a clamping piece 14 and a spring 17, wherein the outer diameter of the fixing stud 6 is 5mm, and the fixed bracket 1 and the measuring support 4 are respectively provided with two φ5mm cylindrical grooves. One side of the two fixing studs 6 is inserted into the cylindrical groove of the fixed bracket 1, and the other side is inserted into the cylindrical groove of the measuring support 4. The two fixing studs 6 are in a fixed and parallel state. The clamping slider 3 has two φ5mm circular through holes, which can pass through the two fixing studs 6 and are installed between the fixed bracket 1 and the measuring support 4. The inner diameter of the spring 17 is φ5.1mm, and it can be sleeved on the outer surface of two φ5mm fixed studs 6. One end of the spring 17 contacts the fixed bracket 1, and the other end contacts the clamping slider 3. The clamping slider 3 can slide on the fixed stud 6 in the X-axis direction with the help of the spring 17. The X-axis clamping piece 14 is fixed to the clamping slider 3 by two M2.5 screws 15, and can slide synchronously with the clamping slider 3, and is used for fitting and clamping the tool in the X-axis direction. The Y-axis direction clamping mechanism is mainly composed of a movable limit stud 9, a U-shaped limit support 10, an M4 fixing bolt 11, a Y-axis clamping piece 16, a spring 17, and a limit nut 18, wherein one side of the Y-axis clamping piece 16 is used to fit and fix the tool, and the other side is provided with two φ5mm internal threaded holes. The movable limit stud 9 has φ5mm threads at both ends, and one end of the two movable limit studs 9 is screwed into the internal threaded holes of the Y-axis clamping piece 16 for fixing. The U-shaped limit support 10 is fixed to the housing 2 by two M4 fixing bolts 11, which are provided with two φ5.1mm through holes. Similarly, two φ5.1mm through holes are also opened on the side wall of the housing 2, so that the other end of the movable limit stud 9 can pass through the through holes of the U-shaped limit support 10 and the housing 2 at the same time. Finally, two limit nuts 18 are installed at the threads of the other end of the movable limit stud 9 for limiting and fixing the clamping mechanism in the Y-axis direction. The spring 17 is also sleeved on the two movable limit studs 9 and installed between the U-shaped limit support 10 and the Y-axis clamp 16. Due to the force of the spring 17, the Y-axis clamp 16 can press the tool during measurement. A through hole is provided in the middle of the U-shaped limit support 10 for installing the displacement sensor 12. The displacement sensor 12 passes through the U-shaped limit support 10 and is fixed with a sensor nut 13. The reset spring inside the sensor can realize the extension and retraction of the measuring head. At the same time, the sensor head contacts the end face of the Y-axis clamp 16. Therefore, the movement of the Y-axis clamp 16 will drive the displacement sensor 12 head to generate displacement, realizing the displacement electrical signal collection of the sensor. The linkage bracket 7 is used to connect the X-axis clamp 14 and the Y-axis clamp 16. The lower end of the linkage bracket 7 is inserted into the square groove at the upper end of the X-axis clamp 14 and the Y-axis clamp 16. When the linkage bracket 7 moves in the 45° direction, Figure 6As shown, the X-axis clamping member 14 and the Y-axis clamping member 16 can be driven to move in the X-axis and Y-axis directions respectively. The upper end of the linkage bracket 7 has an internal thread groove, and the cylindrical wrench 8 has an external thread, which can be screwed and fixed on the linkage bracket 7. The top cover 20 is provided with an oblong hole slide groove as shown in FIG. Figure 7 As shown, the operator moves the cylindrical wrench 8 along the oblong hole slide, then inserts the tool from the tool insertion port, and then loosens the cylindrical wrench 8. Due to the reverse force of the spring 17, the X-axis clamping member 14 and the Y-axis clamping member 16 are automatically clamped, so that the tool position is fixed, providing accurate measurement conditions for the sensor. The top cover 20 is fixedly mounted on the housing 2 by four M2 countersunk screws 19. The installation of the above-mentioned structural parts can store and detect a single specification of tool, forming a single-channel detection device. Since each operator is equipped with multiple specifications of tools, a multi-channel tool detection device is designed, such as Figure 8 As shown, the device can store and detect five types of tool specifications. After completing the operation process, the operator randomly inserts the tool into any detection channel for storage. When the tool is used next time, the control system will automatically detect and display the tool specification value of each detection channel, which is convenient for the operator to use and avoid the misuse of the tool.

[0033] The control box housing 25 is used for the installation of each module of the electric control system, and is assembled by four M2 countersunk screws 19 and the control box top cover 21. The displacement sensor 12 in the electric control part adopts a high-precision electromagnetic distance sensor, with a measuring stroke of 5.00mm and a measuring accuracy of up to 0.01mm, which meets the detection requirements. When the displacement sensor 12 moves during measurement, it can output a corresponding analog voltage signal, and transmit it to the control module 27 inside the control box through a cable. The control module 27 adopts the atmega328P system board, which is the main module of the control system. It can communicate with each module and issue corresponding control instructions. The control module 27 can collect the analog voltage signal of the displacement sensor 12, and process the received electrical signal through the 10-bit AD analog-to-digital converter of the atmega328P chip itself, and calculate the telescopic displacement of the displacement sensor 12 through the program, and finally convert the outer diameter value of the tool. The power module 26 uses a 9V rechargeable lithium battery, and the 9V DC voltage is converted into 5V through the step-down module 28. The 5V DC voltage can be used to power the displacement sensor 12, the display screen 23 and the control module 27. The display screen 23 uses a 0.96-inch OLED LCD screen, which is installed on the top cover 20 and is also connected to the control module 27 through a cable. After the displacement sensor 12 measures, the control module 27 drives the display screen 23 to display the tool outer diameter value. The power button 22 uses a metal self-locking switch, which is installed on the control box top cover 21 through a matching nut. It is used to control the opening and closing of the system. When the power button 22 is turned on, all modules are powered on at the same time to prepare for measurement. The reset button 24 uses a metal self-reset button, which is used to restart and refresh the system program, and can realize the detection and update of the tool outer diameter value.
