[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Please see Figures 1-24This invention provides a technical solution: a multifunctional X-ray nondestructive testing device, comprising a base 1, with a robotic arm 2 and a tooling carriage 3 respectively mounted on the top of the base 1. The robotic arm 2 can move in multiple directions and angles on the top of the base 1. The tooling carriage 3 works in conjunction with the robotic arm 2, and can move laterally on the top of the base 1. Different tooling fixtures can be detachably mounted on the tooling carriage 3, including a disc-shaped workpiece inspection fixture, a conical workpiece inspection fixture, and other related fixtures. The mounting platform 21; the inspection robotic arm 2 includes a support 201, a lifting frame 202, a rotating frame 203, a tilting electric cylinder 204, an angle frame 205, a X-ray claw 206, and a detection claw 207. The support 201 is welded and fixed to one side of the top of the base 1. The lifting frame 202 is connected to the inner side of the support 201 through a guide rail seat. The rotating frame 203 is installed on the outer side of the lifting frame 202, and the rotating frame 203 can be rotated on the outer side of the lifting frame 202 by a drive device. The tilting electric cylinder 204 is fixedly installed on the rotating frame 203 through a rotating shaft. The tilting frame 205 is connected to the outer end of the rotating frame 203 and the output end of the tilting electric cylinder 204 via a hinged seat. The X-ray claw 206 and the probe claw 207 are both connected to the two ends of the tilting frame 205 via guide rails. The outer end of the X-ray claw 206 is equipped with an X-ray tube for emitting X-rays, and the outer end of the probe claw 207 is equipped with a flat panel detector for detection. When the inspection robot arm 2 of this structure needs to use the X-ray claw 206 and the probe claw 207 to inspect the workpiece, the lifting frame 202 can move up and down through the guide rail seat and the inner side of the support 201, the rotating frame 203 can rotate through the outer side of the lifting frame 202, and the tilting electric cylinder 204 can drive the tilting frame 205 to tilt. This allows the inspection robot arm 2 to drive the X-ray claw 206 and the probe claw 207 to extend to various designated positions on the workpiece to achieve the purpose of inspection in various directions, angles, and distances. It meets the function of inspecting workpieces of various shapes, has higher versatility, and solves the problem that the existing inspection fixtures have limited angles for the movement of the detection probes and can usually only be adapted to inspecting workpieces of one shape.

[0046] The outer end of the X-ray claw 206 is fixed with a X-ray tube for emitting X-rays by screws, and the outer end of the detector claw 207 is also fixed with a flat plate detector for detection by screws. The X-ray claw 206 and the detector claw 207 with this structure can perform different types of detection on the workpiece at the same time, improving the functionality of the detection robot arm 2.

[0047] The tooling trolley 3 can move laterally on the top of the base 1 and install different tooling fixtures. The tooling trolley 3 includes a movable trolley 301 and a trolley track 302. The trolley track 302 is symmetrically fixed to the top of the base 1 by several support blocks. The movable trolley 301 is movably mounted on the trolley track 302 by its bottom wheels. A rotary motor is installed on one side of the bottom of the movable trolley 301 to drive the bottom wheels of the movable trolley 301. The movable trolley 301 with this structure can move laterally along the trolley track 302 by driving the bottom wheels through the rotary motor. The top of the tooling trolley 3 is provided with several screw holes, and tooling fixtures are installed on the top of the tooling trolley 3 through the screw holes. The tooling trolley 3 with this structure can quickly install different tooling fixtures through the screw holes on the top. This allows the tooling trolley 3 to be set with different tooling fixtures according to the characteristics of the workpiece to meet the needs of clamping and inspecting different workpieces. This avoids the problem that the clamping mechanisms used in the existing inspection tooling are all load-bearing tooling and are usually only suitable for clamping one type of workpiece.

[0048] The guide rail seat connecting the lifting frame 202 and the support 201 includes a rotating rod 2011, rollers 2012, and a belt 2013. The rotating rod 2011 is located at the upper and lower ends inside the support 201, and both ends of the rotating rod 2011 are connected to the inner walls of both sides of the support 201 through bearings. Two rollers 2012 are provided on the outside of the rotating rod 2011, and the rollers 2012 are symmetrically fixedly sleeved on the outside of both sides of the rotating rod 2011. The belt 2013 is connected to the outside of the corresponding set of rollers 2012 for transmission. The rotating rod is also installed on the rear side of the bottom end of the support 201. The motor 2011 rotates, and the motor output end of the bracket 201 extends into the interior of the bracket 201 and is connected to one end of the rotating rod 2011 via a coupling. When the motor at the rear bottom of the bracket 201 is driven, it can drive the rotating rod 2011 at the bottom to rotate. When the rotating rod 2011 rotates, it can drive the roller 2012 to rotate and drive the belt 2013. When the belt 2013 drives, it can drive the lifting frame 202 to move up and down inside the bracket 201, thereby realizing the overall upgrading and adjustment of the outer mechanism of the bracket 201.

[0049] The disc-shaped workpiece inspection fixture includes a fixed base 12. A first support assembly 13, a second support assembly 14, and a third support assembly 15 are disposed on the top side of the fixed base 12. The first support assembly 13 also includes a mounting frame 32, which is considered a right-angled "U" shape. This structure facilitates the installation of a rotating roller 34. A reduction motor 35 is fixedly connected to one side of the mounting frame 32. This structure allows the rotating roller 34 to rotate via the reduction motor 35. The mounting frame 32 is located on the top side of a support arm 31, and the bottom side of the support arm 31 is fixedly connected to the fixed base 12. This structure primarily connects the support arm 31 and supports the disc-shaped workpiece 11 to be inspected. The fixed base 12 serves to connect the support arm 31 and support the disc-shaped workpiece 11 to be inspected. A metal plate; a rotating roller 34 is provided inside the mounting frame 32, and rotating shafts are provided on both sides of the rotating roller 34, which are rotatably connected to the mounting frame 32; this structure can make the rotation of the rotating roller 34 more stable by setting the mounting frame 32; the rotating roller 34 has a conical structure, and one side of the rotating shaft of the rotating roller 34 is connected to the shaft of the reduction motor 35; this structure can conform to the shape of the disc-shaped workpiece 11 to be inspected by setting the rotating roller 34; the first support component 13 has the same structure as the second support component 14 and the third support component 15, and the first support component 13, the second support component 14 and the third support component 15 are respectively arranged in a triangular distribution about the top side of the fixed base 12; this structure can ensure the stability when supporting the disc-shaped workpiece 11 to be inspected.

[0050] The first support assembly 13 includes a support arm 31, and a rotating roller 34 is rotatably connected to the top side of the support arm 31. The inner side of the rotating roller 34 supports the disc-shaped workpiece 11 to be tested. This device can support the disc-shaped workpiece 11 to be tested through the support arm 31 and the rotating roller 34, and at the same time, make the disc-shaped workpiece 11 to be tested a certain height away from the fixed base 12. The space reserved between the fixed base 12 and the disc-shaped workpiece 11 to be tested can be used to place the detection claw 207.

[0051] The working principle of this disc-shaped workpiece inspection fixture is as follows: First, the disc-shaped workpiece 11 to be inspected is placed on the rotating roller 34. Then, the reduction motor 35 is started, which drives the rotating roller 34 to rotate. During the rotation of the rotating roller 34, the disc-shaped workpiece 11 to be inspected is also rotated. This facilitates the detection claw 207 and the X-ray claw 206 to perform all-round inspection of the disc-shaped workpiece 11. After the detection work of the detection claw 207 and the X-ray claw 206 is completed, the reduction motor 35 is turned off, the rotating roller 34 stops rotating, and the disc-shaped workpiece 11 to be inspected is removed to complete the inspection work.

[0052] This disc-shaped workpiece inspection fixture can stably support the disc-shaped workpiece 11 to be inspected, thereby making the inspection of the disc-shaped workpiece 11 smoother and improving inspection efficiency. By setting a first support component 13, a second support component 14, and a third support component 15 on the top of the fixed base 2, the support arms 31 of the first support component 13, the second support component 14, and the third support component 15 are distributed in a triangular structure. The support arms 31 can support the disc-shaped workpiece 11 to be inspected. At the same time, the rotating roller 34 on the top side of the support arm 31 is shaped to fit the outer wall of the disc-shaped workpiece 11 to be inspected, so that the disc-shaped workpiece 11 to be inspected can be more stable during the inspection process. By setting a reduction motor 35, the rotating roller 34 can be driven to rotate. During the rotation of the rotating roller 34, the disc-shaped workpiece 11 to be inspected can be rotated, so that the disc-shaped workpiece 11 to be inspected can cooperate with the detection claw 207 and X-ray claw 206 of the inspection robot arm 2 for inspection, thereby improving inspection efficiency.

[0053] The conical workpiece inspection fixture 21 includes a positioning base 22, and an inclined adjustment base 25 is provided above the positioning base 22. The positioning base 22 is horizontally positioned, and a hinge 23 is fixed to the positioning base 22 by screws. One end of the positioning base 22 and the inclined adjustment base 25 are rotatably connected by the hinge 23. This structure of the positioning base 22 is used for the installation and positioning between the bottom of the conical workpiece inspection fixture 21 and the top of the fixture trolley 3, and the lower end of the inclined part 24 is positioned by the positioning base 22. The hinge 23 makes the positioning base 22 and the inclined adjustment base 25 movably connected, so that the inclined adjustment base 25 can be adjusted in tilt angle under the support of the positioning base 22. The inclined part 24 is installed between the inclined adjustment base 25 and the positioning base 22, so that the inclined adjustment base 25 can be adjusted in tilt angle by the inclined part 24 under the positioning of the positioning base 22.

[0054] The inclined section 24 is provided with an adjusting linkage assembly 41, which consists of two connecting rods connected by a screw to form a V-shaped structure. The other ends of the two connecting rods of the adjusting linkage assembly 41 are movably connected to the positioning base 22 and the inclined adjustment base 25 respectively through hinge seats 23. This structure allows the two sides of the adjusting linkage assembly 41 to rotate relative to the positioning base 22 and the inclined adjustment base 25 respectively. By adjusting the V-shaped structure angle of the adjusting linkage assembly 41, the opening and closing angle between the positioning base 22 and the inclined adjustment base 25 can be adjusted.

[0055] The inclined section 24 is symmetrically provided with connecting rod assemblies 42 on both sides, and each connecting rod assembly 42 is also composed of two connecting rods forming a V-shaped structure. A transverse shaft 43 is movably passed between the connecting rods of the two connecting rod assemblies 42. The other two sides of the connecting rod assembly 42 are also movably connected to the positioning base 22 and the tilt adjustment base 25 respectively through hinge seats 23. This structure allows the connecting rod assembly 42 to be rotated and adjusted relative to the positioning base 22 and the tilt adjustment base 25. A first lead screw adjustment assembly 44 is also installed in the middle of the inclined section 24. The lever adjustment assembly 44 consists of a lead screw, a lead screw nut, and a handwheel. One of the lead screw nuts of the first lead screw adjustment assembly 44 is also movably connected to the screw used to fix the two connecting rods of the adjusting linkage assembly 41, and the other lead screw nut of the first lead screw adjustment assembly 44 is fixed through the horizontal shaft 43. By rotating the handwheel of the first lead screw adjustment assembly 44, the lead screw of the first lead screw adjustment assembly 44 can be rotated, thereby adjusting the distance between the joints of the connecting linkage assembly 42 and the adjusting linkage assembly 41 through the lead screw nut, and thus adjusting the tilt angle of the tilt adjustment chassis 25.

[0056] A tapered adjustment joint assembly 28 is installed above the tilt adjustment chassis 25. The tapered adjustment joint assembly 28 has two parallel guide rails 82, both of which are screwed to the tilt adjustment chassis 25. Rotary connecting parts 83 are symmetrically and movably mounted on each guide rail 82. A second lead screw adjustment assembly 81 is also installed on the tapered adjustment joint assembly 28. In this structure, the rotary connecting parts 83 can move linearly on the guide rails 82. A bearing seat 833 is located in the middle of the rotary connecting part 83, and an upper connecting seat 834 and a lower connecting plate 832 are movably connected to the upper and lower sides of the bearing seat 833, respectively. The lower connecting plate 832 is connected to the guide rails 82. The movable connecting parts on the rail 82 are fixed with screws. A lead screw connecting seat 831 is welded to the side of the shaft seat 833, and the lead screw connecting seat 831 is connected to the lead screw of the second lead screw adjusting assembly 81. This structure of the lead screw connecting seat 831 constitutes the lead screw nut seat of the second lead screw adjusting assembly 81. By rotating the handwheel of the second lead screw adjusting assembly 81, the lead screw of the second lead screw adjusting assembly 81 can move the lead screw connecting seat 831, thereby realizing the adjustment of the position of the rotating connecting part 83. By adjusting the distance between the rotating connecting parts 83 on both sides of the two guide rails 82, the taper formed between the rotating roller assemblies 26 can be adjusted.

[0057] The movement of the upper connecting seat 834 and the lower connecting plate 832 relative to the bearing seat 833 allows the rotating roller fixing plate 27 to rotate relative to the tilt adjustment base 25. The rotating roller fixing plates 27 are symmetrically connected to the tapered adjustment joint assembly 28, and each rotating roller fixing plate 27 is equipped with a rotating roller assembly 26. The rotating roller assemblies 26, positioned by the rotating roller fixing plates 27, are driven by a motor to rotate, adjusting the conical workpiece fixed between the rotating roller assemblies 26 for the detection and adjustment of the conical workpiece. The rotating roller assemblies 26 are angled via the tapered adjustment joint assembly 28. An auxiliary moving track 84 is fixed to one side of the lower end of the roller fixing plate 27 by screws, and the auxiliary moving track 84 is fixed to the upper connecting seat 834 of the lower rotating connector 83 by screws. The other end of the rotating roller fixing plate 27 is fixed to the upper connecting seat 834 of the upper rotating connector 83 by screws. When the angle of the rotating roller fixing plate 27 is adjusted, the connection position between the rotating roller fixing plate 27 and the rotating connector 83 also changes. The auxiliary moving track 84 can guide the movement of the rotating roller fixing plate 27 relative to the rotating connector 83 so that the rotating roller fixing plate 27 can be smoothly adjusted for taper.

[0058] The working principle of the conical workpiece inspection fixture 21 is as follows: The conical workpiece is placed between the rotating roller assemblies 26, and then the taper between the rotating roller assemblies 26 is adjusted by the taper adjustment joint assembly 28 to stabilize the conical workpiece. The second lead screw adjustment assemblies 81 on both sides of the guide rail 82 are rotated respectively, so that the second lead screw adjustment assemblies 81 push the lead screw connecting seat 831 to move, thereby adjusting the spacing of the rotating connecting parts 83 on the same guide rail 82, thereby adjusting the angle of the rotating roller fixing plate 27. The lower connecting plate 832 connects and fixes the rotating connecting parts 83 to the movable connecting parts on the guide rail 82, and the upper connecting seat 834 connects and fixes the rotating connecting parts 83 to the rotating roller fixing plate 27 and the movable connecting parts at the lower end of the auxiliary moving track 84 respectively. At the same time, the shaft seat 833 connects the lower connecting plate 832 to the upper connecting plate 27. The rotation adjustment is performed between the seats 834, and the angle adjustment is performed by the auxiliary rotating roller fixing plate 27. While the angle of the rotating roller fixing plate 27 changes, the auxiliary moving track 84 moves relative to the rotating connecting piece 83. After the taper adjustment is completed, the tilt angle of the conical workpiece is adjusted as needed. The distance between the joints of the adjusting connecting rod assembly 41 and the connecting connecting rod assembly 42 is adjusted by the first lead screw adjusting assembly 44 on the tilting part 24, so that the tilt adjusting base 25 opens and closes relative to the positioning base 22 through the connection of the hinge seat 23, thereby realizing the adjustment of the tilt angle of the tilt adjusting base 25, and thus realizing the adjustment of the tilt angle of the rotating roller assembly 26. The horizontal shaft 43 is used for the connection and fixing between the connecting rod assemblies 42. The rotating roller assembly 26 is driven by the motor to rotate, thereby realizing the rotation adjustment of the conical workpiece, thus completing a series of tasks.

[0059] The conical workpiece inspection fixture 21 can adjust the taper to match the shape of the part according to its characteristics, so as to better rotate the workpiece. At the same time, it can support, rotate and tilt cylindrical or conical workpieces to better inspect and position conical workpieces. The auxiliary conical workpiece inspection fixture 21 uses a cylindrical rotating roller assembly 26 to position the conical workpiece, and drives the rotating roller assembly 26 to rotate through a motor to realize the rotation adjustment of the conical workpiece. The distance between the rotating roller assemblies 26 is adjustable, and the taper can be easily adjusted to adapt to workpieces with different tapers.

[0060] The method of using this invention: When using the multifunctional X-ray nondestructive testing equipment of this invention to inspect a workpiece, firstly, according to the specific specifications and characteristics of the workpiece to be inspected, install an appropriate tooling fixture on the top of the movable carriage 301 through the threaded hole. The tooling fixture is either a disc-shaped workpiece inspection fixture or a conical workpiece inspection fixture 21 as described above. After the tooling fixture is installed, fix the corresponding workpiece on the corresponding tooling fixture. Then, the movable carriage 301 can be driven by a rotary motor to move laterally along the carriage track 302 until the movable carriage 301 moves to a suitable position on the top of the base 1. Then, start the bottom end of the bracket 201. The side motor drives the bottom rotating rod 2011 to rotate. When the rotating rod 2011 rotates, it synchronously drives the roller 2012 to rotate and causes the belt 2013 to drive. When the belt 2013 drives, it drives the lifting frame 202 to rise and fall inside the support 201. The rotating frame 203 can also rotate outside the lifting frame 202. When the tilting electric cylinder 204 is driven, it can drive the tilting frame 205 to tilt. At this time, the inspection robot arm 2 can flexibly drive the X-ray claw 206 and the detection claw 207 to extend to various designated positions of the workpiece to achieve the purpose of inspection in various directions, angles and distances, thereby completing a series of tasks.
