Description

Technical Field

[0001] The utility model belongs to the technical field of X-ray real-time imaging detection, and in particular relates to a ray detection tool with a thick flange cylinder. Background Art

[0002] After the aluminum alloy cylinder castings are cast, they are subjected to X-ray inspection to ensure that their internal quality meets the requirements. During the X-ray inspection, different image quality meters are selected according to the corresponding standards to ensure the detection sensitivity of the different thickness of the workpiece.

[0003] For cylindrical castings, in order to ensure the sensitivity of transillumination, single-wall transillumination is generally adopted, that is, the product is placed vertically in the center of the workbench, and the radiation source extends into the inner cavity of the product from the bottom. High-speed electrons collide with the rod-shaped anode to generate X-rays to detect the product. According to the thickness of the product, the corresponding parameters can be adjusted to detect the internal quality of the product at different thickness positions. Generally, cylindrical aluminum alloy castings have one or more flanges on the outer wall or inner wall. During the solidification process of the flange position, shrinkage, pores and other defects are prone to occur. When the radial thickness of the flange exceeds 50mm, it will exceed the effective transillumination thickness of the equipment, resulting in distortion of the radiation detection results here, and it is impossible to determine the true quality of the interior. When the existing thick flange cylinder is subjected to radiation detection, because the radiation source can only move up and down, after each transillumination, the staff must open the door and enter the lead room to change the transillumination position by manually rotating the product axially and continue transillumination, which is time-consuming and labor-intensive, extremely inefficient, and unsafe. Utility Model Content

[0008] The through hole b is connected to the through hole a through a transverse beam pin.

[0009] When the longitudinal beam slides onto the through hole a on the transverse beam, the concentricity of the through hole a and the through hole b is ≤0.5mm.

[0022] The utility model is described in detail below with reference to the accompanying drawings and specific implementation modes.

[0023] The utility model of the radiographic detection tool with a thick flange cylinder has a structure as follows Figure 1 As shown, it includes: two transverse beams 1, two frames 2, longitudinal beam 3, pillar 4, roller motor 5, first roller 6, second roller 7, transverse beam pin 8, and longitudinal beam pin 9. Since the product will vibrate when entering the lead room with the working platform, the first thing to ensure is the overall stability of the tooling. The two transverse beams 1 and the two frames 2 are welded to form a stable rectangular base. The flatness of the bottom surface of the rectangular base is required to be ≤1mm to ensure stability. The cross section of the transverse beam 1 is "b"-shaped, the "b"-shaped protruding section of the transverse beam 1 faces the inside and a number of through holes a11 are opened on the end surface. Two longitudinal beams 3 are slidably connected between the two transverse beams 1. Flanges are set at both ends of the longitudinal beam 3. A through hole b is opened on the flange that is consistent with the through hole a11. The through hole b is connected to the through hole a11 through the transverse beam pin 8. When the longitudinal beam 3 slides onto the through hole a11 on the transverse beam 1, the concentricity of the through hole a11 and the through hole b is ≤0.5mm. The transverse beam pin 8 can fix the relative position of the longitudinal beam 3 and the transverse beam 1.

[0024] A groove is provided on the upper end face of each longitudinal beam 3 along the length direction, and a plurality of through holes c10 are symmetrically provided on the two sides of each groove; two pillars 4 are symmetrically installed in each groove, and the pillars 4 slide in the groove along the length direction of the longitudinal beam 3. The structure of the pillars 4 is "L" shaped, and the "L" shaped bottom section is located in the groove and the bottom ends are all facing outwards. A plurality of through holes d are provided on the side of the bottom section, and the direction of the through holes d is consistent with the direction of the through holes c10. After the "L" shaped pillars 4 are placed in the grooves, the through holes d are concentric with the through holes c10, and the concentricity is ≤0.5mm. Then the through holes d and the through holes c10 are fixed by the longitudinal beam pins 9, thereby fixing the relative positions of the pillars 4 and the longitudinal beam 3.

[0025] A first roller 6 is installed on the top of one of the pillars 4, and a roller motor 5 is installed on the outside of the pillar 4. The roller motor 5 is connected to a controller, and the control button of the controller is set on the radiation detection operating table. The roller motor 5 is connected to the first roller 6 through a roller chain. The first roller 6 is a rubber roller. The huge friction between the rubber and the product drives the product to be detected to rotate. The other three pillars 4 are installed on the top of the second roller 7. The second roller 7 is a metal roller. After the product to be detected is placed on the four pillars, its stability can be guaranteed. The metal roller and the product to be detected are in hard contact to reduce the friction generated by the contact between the two. The controller controls the roller motor 5 to drive the rubber roller to rotate, thereby driving the product to rotate axially, effectively shortening the radiation detection time and improving work efficiency; avoiding accidental inhalation of ozone and causing physical damage when personnel frequently enter and exit the lead room to rotate products, reducing safety risks, saving time and effort, and being efficient and safe.

[0026] Example 1

[0027] The utility model of the radiographic detection tooling with thick flange cylinder adopts two transverse beams 1 and two frames 2 welded to form a stable rectangular base, with a length of 1400mm, a width of 800mm, and a material of 45# steel. The flatness of the bottom surface of the rectangular base is required to be ≤1mm to ensure stability. The cross-sectional shape of the transverse beam 1 is "b" type, the "b" type protruding section faces the inside and a plurality of Φ15mm through holes a11 are opened on the end surface, and the hole spacing is 100mm. The through holes a11 on the two transverse beams 1 correspond to each other in relative position. The two ends of the longitudinal beam 3 are flanges, and the flanges are placed on the upper end surface of the "b" type protruding section of the transverse beam 1. The horizontal distance between the end surface and the side surface of the transverse beam is 2mm, so as to ensure that the longitudinal beam 3 can slide on the transverse beam. A Φ15mm through hole b is provided on the flange. When the longitudinal beam slides onto the Φ15mm through hole a11 on the transverse beam, the two beam through holes can be concentric, and the concentricity is ≤0.5mm. The transverse beam pin 8 is placed in the hole to fix the relative position of the longitudinal beam 3 and the transverse beam 1.

[0028] The upper end face of the longitudinal beam 3 is provided with a groove along the length direction, with a groove width of 40mm and a depth of 40mm. Six Φ15mm through holes c10 are provided on each side in the length center direction, with the inner side of the transverse beam 1 extending forward 30mm as the starting position, the through hole c10 hole spacing is 30mm, and the height is 20mm above the bottom of the groove. An "L"-shaped pillar 4 is placed in the groove of the longitudinal beam 3, with a bottom length of 130mm and the bottom edge facing outward. The stability of the product can be ensured after it is placed on the pillar. The pillar width is 39mm and it can slide freely along the groove. Two Φ15mm through holes d are set on the side of the bottom section of the "L"-shaped pillar, with a hole spacing of 30mm. After being placed in the groove, the through hole d is concentric with the through hole c10 on the longitudinal beam 3, and the concentricity is ≤0.5mm. Two longitudinal beam pins 9 are placed in the hole to fix the relative position of the pillar 4 and the longitudinal beam 3. A rubber roller is arranged on the upper part of one of the pillars 4, and a roller motor 5 is arranged on the outer side of the pillar. The roller motor 5 is linked to the rubber roller on the pillar through a roller chain, and the product is driven to rotate by the huge friction generated by the rubber and the product. The second rollers 7 on the other three pillars are made of metal. The metal rollers are in hard contact with the product to reduce the friction generated by the contact between the two. The roller motor 5 is connected to a controller, and the control button of the controller is set on the X-ray detection operating table.

[0029] Example 2

[0030] The radiographic inspection tooling of the utility model with a thick large flange cylinder has the following working process: when the inspection tooling of the present embodiment 1 is used to perform radiographic inspection on the cylinder with a thick large flange cylinder, the positions of the transverse beam 1 and the longitudinal beam 3 are adjusted according to the length and diameter of the product, and the transverse beam pins 8 and the longitudinal beam pins 9 are respectively inserted after the adjustment, and the inspection tooling is placed on the rotating equipment workbench of the lead room, and after the product to be inspected is placed on the tooling, the work platform of the rotating equipment is rotated, such as Figure 2As shown, the flaw detection starts after the product to be inspected is parallel to the direction of the ray. After each position is exposed, the control button of the controller controls the roller motor 5 to rotate the rubber roller, thereby driving the product to be inspected to rotate, and then other positions are exposed in turn. After the flange end face is exposed, the rotating equipment workbench is adjusted manually or in the background to rotate the inspection tooling and the product to be inspected as a whole by 45°, and the angle between the flange and the cylinder is exposed, and the roller motor 5 is adjusted again to rotate the product to be inspected, and other angles are exposed in turn.

[0031] In order to increase the versatility of the tooling, multiple through holes c10 are designed on both sides of the longitudinal beam 3 to adjust the distance between the two pillars 4 to achieve an application range of the cylinder diameter of Φ250-Φ600. The pillar distance corresponds to the effective diameter of the product cylinder part as shown in Table 1:

[0032] Table 1

[0033] Pillar spacing (mm) Product effective maximum diameter (mm) 180 250-300 240 300-350 300 350-430 360 430-510 420 510-600

[0034] Example 3

[0035] Take the cylinder with thick flange as the product to be tested, the structure is as follows Figure 2 As shown, the product has a barrel diameter of 500mm, a flange height of 90mm, a flange thickness of 30mm, and a product wall thickness of 20mm. Figure 2 It can be seen from the structural diagram that if the radiation transillumination direction is in the same direction as the flange extension direction, the transillumination thickness is 110mm, which is too thick. If the radiation transillumination direction is in the normal direction of the flange, the transillumination thickness is 30mm, which can achieve smooth transillumination. The radiation detection tooling with a thick flange cylinder of Example 1 of the utility model is now used for radiation detection, and the specific steps are as follows:

[0036] 1. Open the X-ray detection equipment on the rotating equipment workbench and place the detection tooling in the center of the rotating equipment workbench;

[0037] 2. Adjust the spacing between longitudinal beams 3 and pillars 4 according to the product shape and diameter;

[0038] 3. Place the product on the tooling and remotely control the rotating equipment platform to rotate so that the direction of the horizontal beam 1 is parallel to the direction of the transillumination. Figure 2 As shown;

[0039] 4. Close the lead door, adjust the height of the radiation source so that its effective range can cover a certain area of ​​the flange end face, and start to transilluminate the flange end face;

[0040] 5. After transillumination once, click the control button of the roller motor 5 controller to rotate the product axially and transilluminate the remaining positions of the flange end face in turn;

[0041] 6. After the flange end face is inspected, the rotating equipment platform is rotated horizontally by manual or remote control to drive the inspection tooling and the product to rotate horizontally as a whole until the angle between the transillumination direction and the flange end face is 45°. Figure 3 As shown, start to illuminate the angle between the flange and the cylinder;

[0042] 7. After transillumination once, click the control button of the roller motor 5 controller to rotate the product axially, and transillumine the remaining positions of the angle between the flange and the end face in turn;

[0043] 8. After the inspection is completed, the inspection rotating equipment workbench will be removed from the lead room.

[0044] against Figure 2 For the example of a cylinder with a thick large flange, if traditional X-ray inspection is used for the cylinder with a thick large flange, after each exposure, the staff must open the door and enter the lead room to change the exposure position by manually rotating the product axially and continue the exposure. The time used for X-ray inspection of the thick large flange is 40min-45min. However, when the inspection tooling of the utility model is used for inspection, the X-ray inspection time can be shortened to within 15min, and the efficiency is improved by 167%-200%, thereby greatly improving work efficiency.

[0045] The advantages of the radiographic inspection tool with a thick flange cylinder of the utility model are:

[0046] 1) Effectively shorten the X-ray detection time and improve work efficiency;

[0047] 2) Reduce safety risks. The roller motor drives the axial rotation of the test product to avoid manual handling and reduce safety risks that may occur during handling; avoid frequent entry and exit of personnel in the lead room and accidental inhalation of ozone, which may cause physical damage;

[0048] 3) Widely used. Relying on the adjustable function of the support spacing, it can be applied to the X-ray detection of various products with thick and large flanges within the cylinder diameter range of Φ250~Φ600.
