Description

Technical Field

[0001] This utility model relates to the field of quality inspection equipment, and in particular to a multi-angle X-ray quality inspection device. Background Technology

[0002] Traditional casting inspection involves manually placing the workpiece on the inspection turntable and manually inspecting it. After inspection, the workpiece needs to be manually sorted, resulting in a large workload and low efficiency. Due to the different inspection positions, the X-ray position needs to be adjusted multiple times, which also affects the inspection time of the casting. Therefore, a multi-angle X-ray quality inspection device is proposed. Utility Model Content

[0003] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0004] A multi-angle X-ray quality inspection device includes a housing. A fixed platform is horizontally arranged at the bottom of the housing, and a second movable platform is horizontally arranged above the fixed platform. The second movable platform moves horizontally above the fixed platform. A first movable platform is horizontally arranged above the second movable platform and moves horizontally above the second movable platform. Guide columns are vertically arranged on both sides above the first movable platform, and a lifting platform is horizontally arranged between the guide columns, moving vertically between the guide columns. A multi-angle moving mechanism is arranged above the lifting platform and moves synchronously therewith. Items awaiting quality inspection are placed on the multi-angle moving mechanism. The housing is equipped with an X-ray emission source capable of performing X-ray penetration quality inspection on the items placed on the multi-angle moving mechanism. The housing also includes a detector for receiving X-rays emitted by the X-ray emission source. The X-ray emission source and the detector are located on opposite sides of the top of the housing, respectively, and are positioned opposite each other.

[0005] Preferably, the multi-angle moving mechanism includes a support column vertically arranged on the lifting platform, and the support column and the lifting platform are in the same direction of movement. A mounting base is arranged horizontally above the support column, and a drive shaft is arranged horizontally at the top of the mounting base. The drive shaft is equipped with a swing frame that rotates in the same direction as the drive shaft. A workpiece placement platform for placing the metal casting to be inspected is arranged horizontally above the swing frame, and the workpiece placement platform and the swing frame are in the same swing angle. A clamp for clamping and limiting the metal casting to be inspected is arranged above the workpiece placement platform, and the workpiece placement platform rotates on its own axis above the swing frame.

[0006] Preferably, a third motor is provided on one side of the mounting base, and the third motor is driven to drive the drive shaft. When the drive shaft is rotated by the third motor, the swing frame can swing, and the workpiece placement table is driven to swing at the same time. A first motor is provided at the connection between the swing frame and the workpiece placement table, and the first motor is horizontally mounted on one side above the swing frame, and the first motor is driven to drive the workpiece placement table.

[0007] Preferably, the guide column is fitted with a protective frame, and the protective frame is vertically mounted on a first movable platform. A second motor is horizontally mounted on one side of the outer side of the protective frame to drive the lifting platform to move up and down between the guide columns. The second motor is driven by a screw drive to drive the lifting platform and the multi-angle moving mechanism to move up and down.

[0008] Preferably, a display screen electrically connected to the detector is provided on one side of the outer shell, and an operation panel electrically connected to the detector and the X-ray emission source is provided at a location away from the display screen below, and the operation panel is electrically connected to the display screen.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: When the metal casting to be inspected is clamped on the multi-angle moving mechanism, the multi-angle moving mechanism, together with the metal casting to be inspected, is moved to below the X-ray emission source through the moving cooperation between the second moving stage and the first moving stage. At this time, when the lifting stage and the multi-angle moving mechanism are driven to rise to the horizontal line relative to the X-ray emission source and the detector, the X-ray emission source emits X-rays that can penetrate the metal casting. While the X-rays penetrate the metal casting, the multi-angle moving mechanism rotates the metal casting at different angles, so that X-rays can penetrate the surface of different positions of the metal casting. At the same time, the detector receives the X-rays emitted by the X-ray emission source. Since the materials with different densities and thicknesses inside the metal casting absorb different amounts of X-rays when the X-rays penetrate the surface of the metal casting at different positions, the intensity distribution of the rays after passing through the metal casting is uneven. These rays with different intensities are projected onto the detector, forming a light and dark contrast image reflecting the internal structure of the metal casting, thereby realizing the detection of the internal porosity of the metal casting.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-6In this embodiment of the invention, the multi-angle X-ray quality inspection device includes a housing 1. A fixed platform 11 is horizontally arranged at the bottom of the housing 1, and a second movable platform 12 is horizontally arranged above the fixed platform 11. The second movable platform 12 moves horizontally above the fixed platform 11. A first movable platform 9 is horizontally arranged above the second movable platform 12 and moves horizontally above the second movable platform 12. Guide columns 13 are vertically arranged on both sides above the first movable platform 9, and a lifting platform 14 is horizontally arranged between the guide columns 13. The platform 14 moves up and down between the guide columns 13. A multi-angle moving mechanism that moves synchronously with the platform 14 is installed above it, and items awaiting quality inspection are placed on top of the multi-angle moving mechanism. The housing 1 is equipped with an X-ray emission source 6 capable of performing X-ray penetration quality inspection on the items placed on top of the multi-angle moving mechanism. The housing 1 also has a detector 20 for receiving X-rays emitted by the X-ray emission source 6. The X-ray emission source 6 and the detector 20 are located on opposite sides of the top interior of the housing 1. The two moving platforms are positioned relative to each other. When the metal casting to be inspected is clamped on the multi-angle moving mechanism, the moving platform 12 and the moving platform 9 move together to move the multi-angle moving mechanism and the metal casting to be inspected to a position below the X-ray emission source 6. At this time, the lifting platform 14 and the multi-angle moving mechanism are driven to rise to a horizontal position relative to the X-ray emission source 6 and the detector 20. The X-ray emission source 6 emits X-rays that can penetrate the metal casting. While the X-rays penetrate the metal casting, the multi-angle moving mechanism rotates the metal casting at different angles, allowing X-rays to penetrate the surface of different positions of the metal casting. At the same time, the detector 20 receives the X-rays emitted by the X-ray emission source 6. Since the materials with different densities and thicknesses inside the metal casting absorb different amounts of X-rays when the X-rays penetrate the surface of the metal casting at different positions, the intensity distribution of the rays after passing through the metal casting is uneven. These rays with different intensities are projected onto the detector 20, forming a light and dark contrast image reflecting the internal structure of the metal casting, thereby realizing the detection of the pores inside the metal casting.

[0021] The multi-angle moving mechanism includes a support column 15 vertically mounted on the lifting platform 14, with the support column 15 and the lifting platform 14 moving in the same direction. A mounting base 19 is horizontally mounted above the support column 15, and a drive shaft 18 is horizontally mounted at the top of the mounting base 19. The drive shaft 18 is equipped with a swing frame 16 that rotates in the same direction. A workpiece placement platform 5 is horizontally mounted above the swing frame 16 for placing metal castings to be inspected. The workpiece placement platform 5 and the swing frame 16 swing at the same angle. Above the placement table 5 is a clamp (not shown in the figure) for clamping and limiting the metal casting to be inspected. The workpiece placement table 5 rotates above the swing frame 16. When the metal casting to be inspected is placed on the workpiece placement table 5, the clamp clamps and limits the metal casting. At the same time, the workpiece placement table 5 rotates, thereby turning different faces of the metal casting toward the X-ray emission source 6. While rotating, the swing frame 16 can also swing other faces of the metal casting toward the X-ray emission source 6 so that subsequent X-rays can penetrate.

[0022] A third motor 17 is provided on one side of the mounting base 19, and the third motor 17 is driven to drive the drive shaft 18. When the third motor 17 drives the drive shaft 18 to rotate, the swing frame 16 swings. While the swing frame 16 swings, it drives the workpiece placement stage 5 to swing, so that the upward-facing end face of the metal casting faces the X-ray emission source 6. A first motor 8 is provided at the connection between the swing frame 16 and the workpiece placement stage 5. The first motor 8 is horizontally mounted on one side above the swing frame 16 and is driven to drive the workpiece placement stage 5. The first motor 8 drives the workpiece placement stage 5 to rotate above the swing frame 16.

[0023] The guide post 13 is fitted with a protective frame 4, and the protective frame 4 is vertically mounted on the first moving platform 9. A second motor 10 is horizontally mounted on one side of the outer side of the protective frame 4 to drive the lifting platform 14 to move up and down between the guide post 13. The second motor 10 uses a screw drive to drive the lifting platform 14 and the multi-angle moving mechanism to move up and down.

[0024] A display screen 2 electrically connected to the detector 20 is provided on one side of the outer shell 1, and an operation panel 3 electrically connected to the detector 20 and the X-ray emission source 6 is provided at a position away from the display screen 2. The operation panel 3 is electrically connected to the display screen 2, so that the detector 20 and the X-ray emission source 6 can be controlled through the operation panel 3.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
