[0034] The following is further explained in detail through specific implementation methods.

[0035] like Figures 1 to 8 As shown, the present invention provides an immersion ultrasonic testing device for special aluminum alloy profiles for aviation, including a testing device body 1 and a loading and unloading transmission device. The testing device body 1 includes a profile frame 3, a gantry frame 6, a stainless steel water tank 5, a water tank lifting roller mechanism (lifting roller mechanism 12), a Z-axis scanner 8, and a secondary calibration test block frame. The loading and unloading transmission device includes a loading transmission device 2 and a unloading transmission device 4. Figure 1 As shown, the loading and conveying device 2 is arranged at the left end position of the detection device body 1, and the unloading and conveying device 4 is arranged at the right end position of the detection device body 1.

[0036] The profile frame 3 is welded with stainless steel profiles. A profile support seat is connected to the top of the profile frame 3 by screws. Soft materials are used in the profile support seat to support the profile. For different profiles, profile support seats of different specifications can be replaced to adapt to the support and fixation of the profile to be inspected. The workpiece 9 to be inspected is arranged on the profile support seat on the profile frame 3.

[0037] The feeding and conveying device 2 is arranged at one end of the stainless steel water tank 5 and docked with the stainless steel water tank 5 in the width direction. The feeding and conveying device 2 is composed of multiple groups of modules, each group of modules includes a support frame 10, a conveying roller and a guide wheel at the upper end of the support frame 10, and the guide wheels are arranged and installed on both sides of the support frame to ensure that the profile frame placed on the feeding and conveying device moves along the length direction of the feeding and conveying device, so as to realize the transmission movement guidance of the profile frame. The profile frame 3 can be placed on the feeding and conveying device 2, and the motor on the feeding and conveying device 2 drives the roller to move, and the roller drives the profile frame 3 to move along the length direction of the feeding and conveying device 2 to realize the transmission of the profile frame 3. An existing profile turning system is arranged at the bottom of the feeding and conveying device 2 to realize the turning of the profile on the profile frame. An existing wind knife system is installed at the docking point between the feeding and conveying device 2 and the stainless steel water tank 5 to realize the removal of water stains attached to the profile frame and the profile surface that moves to the feeding and conveying device 2 in the stainless steel water tank 5.

[0038] The unloading transmission device 4 is arranged at the other end of the stainless steel water tank 5 and docked with the stainless steel water tank 5 in the width direction. The unloading transmission device is composed of multiple groups of modules, each group of modules includes a support frame, a conveying roller and a guide wheel at the upper end of the support frame. A profile rack can be placed on the unloading transmission device 4, and the motor on the unloading transmission device 4 drives the roller to move, and the roller drives the profile rack to move along the length direction of the unloading transmission device 4 to realize the transmission of the profile rack. A profile turning system is arranged at the bottom of the unloading transmission device 4 to realize the turning of the profile on the rack. A wind knife system is installed at the docking point between the unloading transmission device 4 and the stainless steel water tank 5 to remove water stains attached to the profile rack and the profile surface that moves from the stainless steel water tank to the unloading transmission device. The unloading transmission device 4 has the same structure as the loading transmission device 2, except that one is used for loading and the other is used for unloading.

[0039] The stainless steel water tank 5 adopts a multi-section splicing structure, and the splicing is sealed with rubber and a pressure plate. The multi-section splicing structure is easy to transport, and the difficulty of on-site implementation is relatively small, and it can be assembled at the installation site. When the length of the workpiece to be inspected is short, a long water tank with an integral rectangular structure can be used. When the size of the workpiece to be inspected is long, a long water tank with a rectangular structure can also be used, and welding and assembly can be performed at the installation site. A set of independent lifting roller mechanisms 12 are arranged at the bottom of each section of the water tank. A high-strength steel support frame is installed on the outside of the stainless steel water tank 5 to ensure the support stability of the water tank. The size specifications of the stainless steel water tank 5 can simultaneously meet the detection of multiple long aluminum alloy profiles (workpiece to be inspected 9), or the detection of a single longer aluminum alloy profile. The stainless steel water tank 5 adopts a multi-module distributed water circulation treatment system, which is arranged on the outside of the stainless steel water tank 5 and connected to multiple water inlets of the stainless steel water tank 5 through water pipes. The distributed water circulation treatment system 5 can improve the purification efficiency. The water tank adopts a reasonable design of independent inlet and outlet, and the outlet is at the lowest point of the water tank.

[0040] The roller mechanism in the stainless steel water tank 5 adopts multiple sets of independent lifting roller mechanisms 12. The overall lifting of each set of independent lifting roller mechanism modules is driven by the screw nuts on both sides. Two sets of C-shaped guide wheels are arranged on the two sets of screws to cooperate and guide with the guide rails on the side of the water tank. The dual motor drive can realize the lifting and lowering movement of a single roller module. The transmission of the roller adopts multi-chain connection and single motor drive to realize the transmission of independent roller modules, avoiding the jamming of the lifting roller mechanism 12 caused by the overall asynchronous movement. The lifting roller mechanism 12 can move up and down. When it is in the raised state, the lifting roller mechanism 12 in the water tank is docked with the loading and unloading transmission device to realize the transmission of the workpiece material rack between the loading and unloading transmission device and the water tank. When the lifting roller mechanism 12 in the water tank is in the lowered state, the profile rack 3 equipped with multiple profiles is lowered as a whole to the bottom of the stainless steel water tank 5, and water immersion ultrasonic testing is implemented.

[0041] The lifting roller mechanism 12 is a structure belonging to the stainless steel water tank 5. The lifting roller structure 12 is arranged horizontally in the stainless steel water tank, and the lifting roller structure 12 is respectively connected to the screw nuts on the inner walls of both sides of the stainless steel water tank 5. The lifting device motor component 15 drives the screw to rotate, and the screw rotation drives the nut on the screw to move up and down along the screw axis direction, and is guided by two sets of C-shaped guide wheels on both sides of the screw and the guide rails on the water tank, so that a single roller module 12 can move vertically in the stainless steel water tank 5.

[0042] A secondary calibration device is installed at the bottom of the stainless steel water tank 5 on both sides of the inside of the stainless steel water tank 5, along the length direction of the stainless steel water tank 5, between the stainless steel water tank wall and the lifting roller mechanism 12, and the detection ultrasonic probe 20 on the Z-axis scanner 8 can be calibrated underwater as required. The secondary calibration device is installed at the bottom of the water tank, and the detection device can perform secondary calibration of the ultrasonic probe in the stainless steel water tank, which has high calibration efficiency and avoids stopping the inspection device to perform manual calibration with the test block in order to perform secondary calibration of the ultrasonic probe, which takes a long time and affects the inspection efficiency of the inspection system.

[0043] Ground rails are arranged on both sides of the stainless steel water tank 5, and the ground rails are connected to the ground. Two gantries 6 are arranged on the ground rails, and the gantries 6 can move back and forth along the length of the water tank on the ground rails. Two Z-axis scanners 8 are installed on each gantry 6 through a guide rail slider. The Z-axis scanner 8 contains X, Y, Z, A, and B motion axes, X, Y, and Z are linear motion axes, and A and B are rotation axes. The gantry 6 is welded with profiles, and then precision-processed after aging treatment after welding to ensure sufficient stability and reliability. All motion axes are equipped with contact limit switches and mechanical hard limits, and all transmission shafts are designed with a semi-enclosed structure to ensure the safety of motion transmission. The X, Y, and Z axis motors are designed with waterproof and dustproof covers to ensure the safe operation of the motors. The A and B motion axes (rotational axes 19) are made of stainless steel to ensure the rust and corrosion protection requirements for long-term underwater use. The X, Y, Z, A, and B motion axes are connected by screws. The A and B axis components adopt a combination of static and dynamic sealing rings on the mating surfaces, and pass compressed air to ensure the waterproof sealing of the A and B axes. Regarding the setting of the X, Y, Z, A, and B motion axes, the X axis is the scanning axis of the scanner, and the scanner moves along the length direction of the workpiece to be inspected; the Y axis is the stepping axis of the scanner, and the scanner moves along the width direction of the workpiece to be inspected; the Z axis is the height position adjustment axis of the scanner, and it moves along the height direction of the workpiece to be inspected; the A and B axes are the rotating axes of the scanner, in order to ensure the relative position between the ultrasonic probe on the scanner and the workpiece to be inspected in view of the bending deformation of the workpiece to be inspected.

[0044] like Figure 7As shown, a lifting roller mechanism 12 is provided in the stainless steel water tank 5, and a lifting roller transmission motor component 16 drives the lifting roller mechanism 12 to move in the height direction of the stainless steel water tank. The lifting device 13 is installed on the inner walls on both sides of the length direction of the stainless steel water tank. A plurality of lifting devices 13 are symmetrically arranged on the inner side of the stainless steel water tank. Each independent lifting device 13 adopts a screw nut transmission method, and two groups of C-shaped guide wheels are arranged on the screw side to cooperate with the guide rails on the side of the water tank for guiding. The screw is vertically fixed on the inner wall of the stainless steel water tank through bearing seats at both ends. The nut on the screw is connected to the lifting roller mechanism, and the upper end of the screw is connected to the lifting device motor component 15. The structure of the lifting device motor component 15 is biased toward the outside of the stainless steel water tank, thereby reducing the space occupied by the lifting device motor component 15 in the stainless steel water tank. The lifting device motor component 15 drives the screw to rotate, and the screw rotation drives the nut on the screw to move up and down along the screw axis, and is guided by two sets of C-shaped guide wheels on both sides of the screw and the guide rails on the water tank, so as to realize the vertical lifting movement of a single roller module in the stainless steel water tank.

[0045] like Figure 8 As shown, the gantry scanner includes a gantry 6, an X-axis component 7, a Z-axis scanner 8, a Z-axis motor component 17, a laser rangefinder 18, a rotating axis 19 (A, B motion axes), a detection ultrasonic probe 20, and a Y-axis component 21.

[0046] The X-axis component 7 is slidably connected to the ground rail, so that the gantry scanner can slide on the ground rail. The X-axis component 7 is, for example, a slider.

[0047] The Y-axis component 21 is disposed on the crossbeam of the gantry 6 and arranged parallel to the axis of the crossbeam, and is used to move the Z-axis scanner 8 along the Y-axis direction. The Y-axis component 21 is, for example, a matching component of a guide rail and a guide rail slider.

[0048] The X-axis direction is along the ground rail, the Y-axis direction is the length direction of the beam of the gantry 6, and the Z-axis direction is the height direction of the gantry 6. In addition, the A and B motion axes are rotation axes. The A motion axis is a rotational motion along the ground rail as the axis direction, and the B motion axis is a rotational motion along the length of the beam of the gantry 6 as the axis direction.

[0049] The rotating shaft 19 (A and B moving shafts) is installed at the lower end of the Z axis, arranged perpendicularly to the Z axis direction, and the other end is connected to the detection ultrasonic probe. The A moving shaft and the B moving shaft are perpendicular to each other. The rotating shaft 19 (A and B moving shafts) is the rotating shaft of the detection ultrasonic probe. In view of the bending deformation of the workpiece to be inspected, the relative position between the detection ultrasonic probe and the workpiece to be inspected is ensured.

[0050] The rotating shaft 19 is installed at the bottom of the Z-axis scanner 8 to ensure the relative position between the connected detection ultrasonic probe and the workpiece to be inspected in view of the bending deformation of the workpiece to be inspected. The structure adopts a rotary rotation structure, the rotary main structure is fixed, and the output shaft or flange at one end produces relative rotation. The rotating shaft 19 can drive the connected detection ultrasonic probe to rotate around the axis direction along the ground rail and the axis direction along the crossbeam length of the gantry 6 to adapt to the bending deformation of the workpiece to be inspected and ensure the relative position relationship between the connected detection ultrasonic probe and the workpiece to be inspected.

[0051] The detection ultrasonic probe 20 is installed on the rotating shaft 19. The detection ultrasonic probe is driven by the rotating shaft 19 and rotates along the axis of the ground rail and along the axis of the length of the gantry 6 beam to adapt to the bending deformation of the workpiece to be inspected and ensure the relative position relationship between the connected detection ultrasonic probe and the workpiece to be inspected.

[0052] The Z-axis motor component 17 drives the Z-axis scanner 8 to move in the Z-axis direction. Figure 8 shown.

[0053] A laser rangefinder 18 is installed on the Z axis of each Z axis scanner 8, which is fixedly connected with screws to measure the relative position of the workpiece 9 to be inspected (the aluminum alloy profile to be inspected). The movement of the X axis component 7 and the Y axis component 21 can realize the movement measurement along the X and Y axis directions at a fixed height, realize the detection of the outer dimensions and position coordinates of the aluminum alloy profile, and fit the outer structure model of the workpiece. According to the fitted model structure, the movement amount of the five movement axes of the Z axis scanner 8 is solved. The five axes of the Z axis scanner 8 can adjust the movement amount of the five axes according to different inspection parts, so as to realize the accurate detection of each spare part workpiece.

[0054] In order to improve the safety of the probe tray at the end of the Z-axis scanner 8, four contact limit switches are arranged around the detection ultrasonic probe 20 tray. When the tray collides in the detection tank, the contact switch is activated, and the detection system can identify the tray status in time and make safety adjustments.

[0055] When performing the inspection, the operator places the workpiece 9 to be inspected on the special material rack 3, and places the material rack 3 with the workpiece on the loading and conveying device 2. The loading and conveying device 2 docks with the lifting roller mechanism 12 in the stainless steel water tank 5, and transfers the material rack 3 to the top of the material rack support in the water tank. The lifting roller mechanism 12 in the stainless steel water tank 5 moves downward, and the water tank lifting roller mechanism 12 moves downward to the bottom of the end surface of the material rack support, without affecting the supporting effect of the material rack support on the material rack. The gantry 6 at both ends carries the Z-axis scanner 8 and moves along the length direction of the water tank, and inspects the two groups of workpieces along the X-axis direction respectively. The laser rangefinder 18 on the gantry detects and samples the outer dimensions and position coordinates of the workpieces on the material rack 3, fits the outer surface structural features of the workpiece 9 to be inspected, and solves the scanned and fitted workpiece structure and position state to the movement amount of each moving axis of the Z-axis scanner 8, so that the Z-axis scanner 8 on the gantry 6 can realize five-axis movement to perform water immersion ultrasonic inspection on the surface of the workpiece 9 to be inspected. If the system shows that the workpiece has defects, the control system drives the gantry 6 and the Z-axis scanner 8 to move again to perform quantitative detection.

[0056] After the inspection of the single side of the workpiece is completed, the water tank lifting roller mechanism 12 rises and moves to lift the profile rack 3 on the rack support, and the water tank lifting roller mechanism 12 is flush with the outer loading and unloading transmission device 4, and the roller transmission device in the water tank transmits the inspected workpiece 9 to be inspected and the profile rack 3 to the loading and unloading transmission device as a whole, and the door frame type air curtain on the unloading transmission device 4 removes the water stains attached to the surface of the aluminum alloy profile, and the water is collected in the water tank at the bottom of the unloading transmission device 4. The control system controls the auxiliary support component at the lower middle part of the unloading transmission device to lift the workpiece on the rack, and then uses the rotating cylinder modules under the two ends of the unloading transmission device 4 to lift, clamp and rotate to complete the workpiece turning action. After the inspection of the workpiece inspection surface in the water tank is completed, the lifting and transmission mechanism in the water tank transfers the rack in the water tank to the loading transmission device as a whole, and the workpiece rack on the unloading transmission device runs in the reverse direction and is transmitted to the water tank again for inspection until the inspection of multiple surfaces of the workpiece is completed. The inspected workpiece rack is transferred as a whole to the unloading conveyor, and the water stains attached to the workpiece surface are removed by the wind curtain. The operator operates the crane to lift the inspected aluminum alloy profile away from the unloading conveyor. The stainless steel water tank 5 is equipped with a secondary calibration test block, and the detection ultrasonic probe 20 on the Z-axis scanner 8 can be calibrated underwater as required.

[0057] like Fig. 9 As shown, when the present invention is used, its working process is as follows:

[0058] The operator places a plurality of workpieces 9 to be inspected on the profile rack 3a;

[0059] The profile frame 3a is hoisted onto the feeding device roller table 10;

[0060] The operator starts the feeding conveyor 2;

[0063] The molding material rack 3a descends to the bottom of the stainless steel water tank 5 along with the lifting roller mechanism 12 in the water tank;

[0064] The molding material frame 3a is also completely immersed in water;

[0065] The conveying roller at the bottom of the water tank conveys the profile rack 3a to the front end of the stainless steel water tank 5 (the stainless steel water tank 5 can accommodate two sets of profile racks 3 at the same time in the length direction), and then the profile rack 3b repeats the above process until the bottom of the water tank is completely immersed in water;

[0066] The operator sets the detection parameters on the interface;

[0067] The gantry scanner identifies the workpiece 9 to be inspected and performs inspection;

[0068] Two gantry scanners respectively scan two sets of material racks 3a and 3b ( Fig. 9 The inspected workpieces 9 on the gantry 6 are inspected independently, and each gantry 6 has two sets of Z-axis scanners 8, which respectively inspect the four inspected workpieces 9 synchronously.

[0069] After each inspection surface of the inspected workpiece 9 on the two molding material racks 3a and 3b is inspected;

[0070] The lifting roller mechanism 12 in the water tank rises to be flush with the loading and unloading transmission device;

[0071] The inspected mold material racks 3a and 3b are sequentially transferred as a whole to the unloading and conveying device 4 (the unloading and conveying device and the stainless steel water tank 5 continue to carry out loading and lifting movements, workpiece edge inspection and single-side inspection, and the single-side inspection of the mold material racks 3c and 3d is completed. The loading and conveying device no longer places the mold material rack 3. There can be at most 4 sets of mold material racks 3 on the entire inspection device);

[0072] The material rack 3 detected by the stainless steel water tank 5 is automatically transferred to the unloading air knife;

[0073] The air knife starts to blow dry the workpiece;

[0074] On the material transfer device 4, the control system completes the flipping of the detection surfaces of the workpieces 3a and 3b on the two molding material racks on the material transfer device 4 respectively;

[0075] The mold material racks 3c and 3d ( Fig. 9 In the figure, the first and second surfaces are conveyed to the feeding conveyor 2 in reverse direction for turning over;

[0076] The two types of material racks 3a and 3b that have been turned over on the unloading conveying device 4 are conveyed in the opposite direction to the water tank 5 for inspection of the other inspection surface;

[0077] After the inspection of the two types of material racks 3a and 3b in the water tank is completed, they are forwardly conveyed to the unloading conveyor 4 for air drying again. After the inspection is completed, the operator lifts the inspected material racks away;

[0078] The two material racks 3c and 3d on the loading and conveying device 2 that have completed the turning over of the workpiece 9 are forwardly conveyed to the water tank 5 again to inspect the other side. After the inspection is completed, they are conveyed to the unloading and conveying device 4 for air drying to complete the inspection; at the same time, the other two material racks 3e and 3f ( Fig. 9 The parts are represented by E and F in the figure) and are hoisted onto the feeding conveying device 2, and the above working steps of conveying, descending, patrolling, detecting, ascending, conveying and air knife drying are repeated;

[0079] The workpiece inspection on the two-group material rack 3 is completed (the gantry scanner automatically returns to the zero position and waits);

[0080] The operator lifts the material off the operator and starts the workpiece unloading conveyor mechanism (the next cycle begins).
