Detailed Implementation

[0029] 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.

[0030] Example 1

[0031] Reference Figure 1 and Figure 2 and Figure 4 as well as Figure 5 This is the first embodiment of the present invention. This embodiment provides a device with dual-function imaging detection of CT and DR, which can realize all-round automated detection of welded parts and aluminum alloy castings, etc. It has a wide detection range and meets the seamless connection from two-dimensional rapid general inspection to three-dimensional accurate diagnosis, so that no workpiece is missed in the inspection and there will be no hidden dangers when it is put into production. It includes a frame unit 100, a detection unit 200 and a placement unit 300.

[0032] The frame unit 100 includes a work frame 101 and a power assembly 102.

[0033] The detection unit 200, which is disposed on the front of the frame unit 100, includes a connecting part 201 and a detection part 202 located on its side. The detection unit 200 also includes a shielding component 203. The detection unit 200 is used for the forming detection operation of the material.

[0034] The placement unit 300, which is located above the work rack 101, includes a placement part 301 and a clamping part 302 located inside it. The placement unit 300 is used to place and fix the material to be tested.

[0035] In use, the products such as welded parts and aluminum alloy castings that need to be non-destructively inspected are placed in the placement part 301 and clamped and fixed in conjunction with the clamping part 302. At the same time, the placement part 301 can be flipped to start the power component 102, so that the connecting part 201 drives the detection part 202 to inspect the welded parts and aluminum alloy castings. The position can also be adjusted according to actual needs to achieve all-round imaging inspection.

[0036] Example 2

[0037] Reference Figure 1 and Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8 This is the second embodiment of the present invention. Unlike the previous embodiment, the power assembly 102 includes a motor 1021 fixedly connected to the top surface of the work frame 101. The bottom surface of the output rod of the motor 1021 extends through the top surface of the work frame 101 into the interior of the work frame 101 and is fixedly connected to a threaded rod 1022. The surface of the threaded rod 1022 is rotatably connected to the inner wall of the work frame 101.

[0038] Specifically, the connecting part 201 includes a movable block 2011 that is slidably connected to the inner wall of the work frame 101, the surface of the threaded rod 1022 and the inner wall of the movable block 2011 are threadedly connected, a bidirectional hydraulic cylinder 2012 is fixedly installed on the inner wall of the movable block 2011, and two CT detectors 2013 are fixedly installed on the outer sides of the two output rods of the bidirectional hydraulic cylinder 2012 respectively.

[0039] In addition, the detection unit 202 includes a front and rear slide rail 2021 fixedly connected to the top surface of the movable block 2011. The front and rear slide rail 2021 is slidably connected to the surface of the left and right slide rail 2022. The DR detector 2023 is slidably connected to the surface of the left and right slide rail 2022. The shielding assembly 203 includes a placement frame 2031 fixedly connected to the outer side of the front and rear slide rail 2021. Shielding curtains 2032 are pasted on the left and right end surfaces of the placement frame 2031. Cover curtains 2033 are rotatably connected to the outer top of the two shielding curtains 2032. The two shielding curtains 2032 are snapped together by buckles 2034 provided on the front.

[0040] In use, the motor 1021 is started, causing the threaded rod 1022 to rotate. Through the transmission action of the toothed pulley 1023 and the toothed belt, the arc frame 3011 rotates, thereby driving the moving block 2011 to move up and down. The bidirectional hydraulic cylinder 2012 is started, which can drive the CT detectors 2013 at both ends to adjust the spacing. The CT detectors 2013 can quickly inspect the items from both sides. The DR detector 2023 can move freely forward, backward, left, right, and up and down through the front and rear slide rails 2021 and the left and right slide rails 2022, thereby ensuring that each part of the item can be inspected at a fixed point. Before inspection, the shielding curtain 2032 can be attached to the surface of the placement rack 2031, and the cover curtain 2033 can be used to block the top. The shielding curtain 2032 can move up and down along the moving block 2011, always keeping the inspection space free from external factors.

[0041] The placement unit 301 includes an arc-shaped frame 3011 rotatably connected to the inner wall of the work frame 101. The bottom surfaces of the arc-shaped frame 3011 and the threaded rod 1022 are both fixedly fitted with toothed pulleys 1023. The two toothed pulleys 1023 are connected by a toothed belt drive. A turntable 3012 is fixedly installed on the side of the arc-shaped frame 3011. A hydraulic cylinder 3013 is fixedly installed on the inner wall of the turntable 3012. A connecting block 3014 is fixedly installed on the top surface of the output rod of the hydraulic cylinder 3013. A telescopic rod 3015 is rotatably connected to the inner wall of the connecting block 3014. A slider 3016 is fixedly installed on the right end face of the output rod of the telescopic rod 3015. The side of the slider 3016 is slidably connected to the inner wall of the arc-shaped frame 3011. A device disk 3021 is rotatably connected to the inner wall of the slider 3016.

[0042] In addition, the clamping part 302 includes two bidirectional telescopic rods 3022 fixedly connected to the inner walls of the front and rear ends of the device disk 3021. The back of the device disk 3021 and the front of the turntable 3012 are rotatably connected. Movable frames 3024 are fixedly provided on the outer sides of the two output rods of the bidirectional telescopic rods 3022. The side of the movable frame 3024 is slidably connected to the inner wall of the device disk 3021. A first spring 3023 is fixedly provided on the inner side of the movable frame 3024 and the inner wall of the bidirectional telescopic rods 3022. A fixed plate 3026 is slidably connected to the inner wall of the movable frame 3024. A second spring 3025 is fixedly provided on the bottom surface of the fixed plate 3026 and the top surface of the movable frame 3024.

[0043] In use, the welded parts and aluminum alloy castings to be inspected are placed on the device plate 3021. The telescopic characteristics of the bidirectional telescopic rod 3022 and the first spring 3023 drive the moving frame 3024 to clamp and fix both ends of the product. The top surface is firmly fixed by the action of the second spring 3025 and the fixing plate 3026. Through the transmission action of the power component 102, the arc frame 3011 can rotate 360 ​​degrees laterally to cooperate with the CT scanner 2013 for inspection. The hydraulic cylinder 3013 is activated, and the up and down movement of the connecting block 3014 causes the telescopic rod 3015 to extend and retract, which in turn causes the slider 3016 to slide inside the arc frame 3011, causing the device plate 3021 to flip. At the same time, it cooperates with the CT scanner 2013 and the DR scanner 2023 to perform multi-directional inspection.
