Figure 1 As shown, the trumpet-shaped casting radiographic inspection tool 100 includes a tool seat body 10 and an adjustment bracket; wherein the tool seat body 10 includes a tool vehicle 11 and a base 12 horizontally arranged on the tool vehicle 11, and the base 12 rotates 360° in the horizontal direction relative to the tool vehicle 11; the adjustment bracket is arranged on the base 12, and is used to horizontally load trumpet-shaped castings of different lengths and different calibers to be tested, and the trumpet-shaped casting to be tested rotates along its circumferential direction relative to the adjustment bracket. The base 12 of the present invention has a load-bearing function, and the base 12 rotates 360° in the horizontal direction, thereby driving the adjustment bracket and the trumpet-shaped casting to be tested loaded on the adjustment bracket to rotate.

[0053] In the embodiments of the present invention, through the coordinated cooperation of the tooling seat and the adjustment bracket, firstly, the trumpet-shaped casting is quickly flipped horizontally during the X-ray detection process, thereby shortening the detection time, reducing the difficulty of manual operation, and improving the detection efficiency and the consistency of the detection film; secondly, the trumpet-shaped casting X-ray detection tooling is adaptable to trumpet-shaped castings of different sizes, thereby improving practical flexibility and extensiveness, and can be applied to clamping X-ray detection of various trumpet-shaped castings; finally, the design of the adjustment bracket can avoid scratches, marks and other damages on the casting surface during the clamping process of the casting, and the structure is reliable and stable.

[0054] Continue to see Figure 2 As shown, the tooling vehicle 11 includes a bottom plate 111, on which a mounting groove is provided, and a rotating table 13 is provided in the mounting groove to avoid center deviation and dislocation caused by frequent rotation of the rotating table 13 and improve stability. The base 12 is installed on the rotating table 13, and the operator can rotate the rotating table 13 according to the relative position required for the X-ray detection of the casting in order to reach a suitable position. The rotating table 13 in the present invention is used to drive the base 12 to rotate relative to the tooling vehicle 11. The setting of the rotating table 13 is convenient for rotating the base 12 after the tooling vehicle 11 is fixed in the X-ray machine probe transillumination area, adjusting the relative position of the trumpet-shaped casting to be tested in the X-ray detection area, saving operation time and improving detection efficiency.

[0055] In the embodiment of the present invention, scale lines are provided on the rotating table 13 to record the special positions where different castings need to be placed during radiographic transillumination, thereby improving detection efficiency.

[0056] In the embodiment of the present invention, the rotating platform 13 is divided into two layers, the lower layer is arranged in the installation groove, and the upper layer and the lower layer are inlaid together through the clamping groove, and the rotation thereof depends on the ball disposed in the clamping groove.

[0057] In an embodiment of the present invention, the tooling vehicle 11 further includes a plurality of wheels 112, such as a plurality of universal wheels, mounted on the bottom plate 111, and a push-pull rod 113 mounted on the bottom plate 111. The tooling vehicle 11 is mainly used to place and transport castings to reduce the difficulty of operation, wherein the plurality of wheels 112 can be fixed on the bottom plate 111 by welding, and the plurality of wheels 112 are specifically mounted on the side of the bottom plate 111 opposite to the rotating table 13, that is, the bottom of the bottom plate 111. The arrangement of the wheels 112 facilitates the movement of the tooling vehicle 11 to adjust the detection area of ​​the casting in the center beam of the X-ray machine. The push-pull rod 113 is arranged at the end position of the bottom plate 111 to facilitate the push-pull operation.

[0058] In some embodiments of the present invention, a lock is provided on the wheel 112 to prevent the tooling vehicle 11 from moving along with the axial rotation of the casting after it stops. For example, the lock is locked to fix the tooling vehicle 11 after the adjustment is completed.

[0059] Continue to see Figure 1 As shown, according to the special structural shape of the trumpet-shaped casting, the adjustment bracket in the present invention includes a first bracket assembly 20 and a second bracket assembly 30, which can also be understood as being divided into a lateral adjustment bracket and a longitudinal adjustment bracket according to the different positions of the bearing casting. The first bracket assembly 20 and the second bracket assembly 30 are respectively arranged on opposite sides of the base 12 and the relative positions of the two are adjustable. The first bracket assembly 20 (lateral adjustment bracket) corresponds to the larger diameter side of the trumpet-shaped casting to be tested, and the second bracket assembly 30 (longitudinal adjustment bracket) corresponds to the smaller diameter side of the trumpet-shaped casting to be tested, so that the middle part of the trumpet-shaped casting to be tested is suspended.

[0060] Continue to see Figure 1 As shown, the first bracket assembly 20 mainly includes a first support plate 21 and two first arc-shaped brackets 22 arranged on opposite sides of the first support plate 21, and the arc-shaped openings of the two first arc-shaped brackets 22 are arranged relatively to form a accommodating space for carrying the large-diameter side of the trumpet-shaped casting to be tested, and the two first arc-shaped brackets 22 are rotatably connected to the first support plate 21 respectively to adjust the accommodating space and are suitable for carrying trumpet-shaped castings of different calibers to be tested.

[0061] In an embodiment of the present invention, each first arc bracket 22 is arranged on the first support plate 21 through a support base 23, and the first arc bracket 22 is detachably rotatably connected to the support base 23. Specifically, a support base 23 is arranged on opposite sides of the first support plate 21, and the bottom of the support base 23 is arranged on the first support plate 21, for example, it can be fixed on the first support plate 21 by welding, and the top of the support base 23 is rotatably connected to the first arc bracket 22, so that the first arc bracket 22 can rotate in the vertical direction, so that the first arc bracket 22 can be relatively rotated according to the caliber size of the casting to adapt to castings of different calibers. The setting of the first arc bracket 22 in the present invention meets the curvature of the trumpet-shaped casting, and the first arc bracket 22 is detachably arranged on the support base 23. When the caliber of the trumpet-shaped casting is relatively large, the first arc bracket 22 that meets the requirements can be selected for replacement.

[0062] In some embodiments of the present invention, the first arc-shaped bracket 22 is connected to the support base 23 via a first bayonet 24. The connection method of the first bayonet 24 realizes the detachable connection of the first arc-shaped bracket 22 and facilitates the relative rotation of the first arc-shaped bracket 22 according to the caliber of the casting.

[0063] Continue to see Figure 1 As shown, the first rolling members are respectively arranged at the opposite ends of each first arc-shaped bracket 22 to drive the circumferential rotation of the trumpet-shaped casting to be tested and to limit the trumpet-shaped casting to be tested. In the embodiment of the present invention, the first rolling member includes a first driving wheel 25 and a first driven wheel 26, that is, a customized wheel is installed on each side of the first arc-shaped bracket 22. Specifically, the upper side of the first arc-shaped bracket 22, which can also be understood as the side away from the first support plate 21, is installed with the first driven wheel 26, and the lower side of the first arc-shaped bracket 22, which can also be understood as the side close to the first support plate 21, is installed with the first driving wheel 25, wherein the first driving wheel 25 mainly plays the role of bearing, driving the circumferential rotation of the trumpet-shaped casting and limiting the position. The outer side of the trumpet-shaped casting to be tested is loaded between the first driving wheel 25 and the first driven wheel 26, so as to firmly carry the casting.

[0064] In the embodiment of the present invention, the size and weight of the first driving wheel 25 are slightly larger than the first driven wheel 26. The first driving wheel 25 with a larger diameter plays a limiting role, and the first driven wheel 26 with a smaller diameter plays a rotating and supporting role. The two cooperate to control the detection state of the first arc-shaped bracket 22. The first driving wheel 25 and the first driven wheel 26 are both made of polyester.

[0065] Continue to see Figure 1As shown, the first support plate 21 is horizontally arranged on the base 12, and a driving wheel 27 is installed below the first support plate 21, that is, on the side opposite to the support base 23, which mainly plays a load-bearing and moving role, and is used to drive the first bracket assembly 20 to move, and has a certain load-bearing role; for example, the first bracket assembly 20 can be moved according to the requirements of trumpet-shaped castings of different lengths, such as in some cases, it can be manually driven to achieve the adjustment of the relative position of the first bracket assembly 20 and the second bracket assembly 30. In some embodiments of the present invention, the driving wheel 27 can be a universal wheel, and a lock is provided on the driving wheel 27 to fix the first bracket assembly 20 at a desired position to prevent it from moving at will.

[0066] Continue to see Figure 1 As shown, the second bracket assembly 30 mainly includes a second support plate 31 and two second arc-shaped brackets 32 arranged on opposite sides of the second support plate 31, the relative positions of the two second arc-shaped brackets 32 are adjustable, and the arc-shaped openings of the two second arc-shaped brackets 32 are relatively arranged to form a accommodating space for carrying the small-diameter side of the trumpet-shaped casting to be tested, and the two second arc-shaped brackets 32 are respectively rotatably connected to the second support plate 31 to adjust the accommodating space and are suitable for carrying trumpet-shaped castings of different calibers to be tested.

[0067] In an embodiment of the present invention, each second arc bracket 32 ​​is detachably arranged on the second support plate 31 through a support frame 33, and the second arc bracket 32 ​​is rotatably connected to the support frame 33. Specifically, a support frame 33 is arranged on each of the opposite sides of the second support plate 31, one end of the support frame 33 is detachably arranged on the second support plate 31, and the other end of the support frame 33 is rotatably connected to the second arc bracket 32, so that the second arc bracket 32 ​​can rotate in the vertical direction, so that the second arc bracket 32 ​​can be relatively rotated according to the caliber size of the casting to adapt to castings of different calibers. The setting of the second arc bracket 32 ​​in the present invention meets the curvature of the trumpet-shaped casting, and the second arc bracket 32 ​​is detachably connected to the support frame 33. When the caliber of the trumpet-shaped casting is relatively large, a second arc bracket 32 ​​that meets the requirements can be selected for replacement.

[0068] In some embodiments of the present invention, the second support plate 31 is vertically arranged on the base 12, and two support frames 33 are vertically arranged on opposite sides of the second support plate 31 along the length direction of the second support plate 31, wherein the lower end of the support frame 33 is connected to the second support plate 31, and the upper end of the support frame 33 is rotatably connected to the second arc bracket 32, so that the second arc bracket 32 ​​can rotate in the vertical direction, so that the second arc bracket 32 ​​can rotate relatively according to the caliber size of the casting to adapt to castings of different calibers.

[0069] In some embodiments of the present invention, the second arc bracket 32 ​​is connected to the support frame 33 via a second bayonet 34. The connection method of the second bayonet 34 realizes the detachable connection of the second arc bracket 32 ​​and facilitates the relative rotation of the second arc bracket 32 ​​according to the caliber of the casting.

[0070] Continue to see Figure 1 As shown, the second support plate 31 is provided with a plurality of groups of adjustment holes 37 along the arrangement direction of the two second arc-shaped brackets 32, and the support bracket 33 is provided on the second support plate 31 through each group of adjustment holes 37. In the embodiment of the present invention, the second support plate 31 is provided with a plurality of groups of adjustment holes 37, which can be used to adjust the relative positions of the two support brackets 33, thereby adjusting the relative positions of the two second arc-shaped brackets 32, and is used to clamp trumpet-shaped castings of different calibers.

[0071] In an embodiment of the present invention, each group of adjustment holes 37 includes multiple holes, and the multiple holes are arranged in a direction perpendicular to the arrangement direction of the multiple groups of adjustment holes. The support frame 33 is installed on the second support plate 31 through the multiple holes, such as using bolts or screws to install the support frame 33 on the second support plate 31.

[0072] It is worth mentioning that in the embodiment of the present invention, multiple groups of adjustment holes can be provided on the first support plate 21 according to actual needs to adjust the relative positions of the two support bases 23, which is suitable for loading trumpet-shaped castings of different calibers.

[0073] Continue to see Figure 1 As shown, the opposite ends of each second arc-shaped bracket 32 ​​are respectively provided with second rolling members, and the second rolling members cooperate with the first rolling members to better drive the circumferential rotation of the trumpet-shaped casting to be tested and limit the trumpet-shaped casting to be tested. In the embodiment of the present invention, the second rolling member includes a second driving wheel 35 and a second driven wheel 36, that is, a custom wheel is installed on both sides of the second arc-shaped bracket 32. Specifically, the upper side of the second arc-shaped bracket 32, which can also be understood as the side away from the second support plate 31, is equipped with the second driven wheel 36, and the lower side of the second arc-shaped bracket 32, which can also be understood as the side close to the second support plate 31, is equipped with the second driving wheel 35. The second driving wheel 35 mainly plays the role of bearing, driving the circumferential rotation of the trumpet-shaped casting and limiting the position. The outer side of the trumpet-shaped casting to be tested is loaded between the second driving wheel 35 and the second driven wheel 36, so as to firmly carry the casting.

[0074] In the embodiment of the present invention, the size and weight of the second driving wheel 35 are slightly larger than the second driven wheel 36 to prevent the second arc-shaped bracket 32 ​​from rotating in the opposite direction and failing to clamp the casting. The second driving wheel 35 with a larger diameter plays a limiting role, and the second driven wheel 36 with a smaller diameter plays a rotating and supporting role, and the two cooperate to control the detection state of the second arc-shaped bracket 32. The second driving wheel 35 and the second driven wheel 36 are both made of polyester.

Specifically, the hydraulic control system is connected in transmission with the first bracket assembly 20 and the second bracket assembly 30 respectively, and the first bracket assembly 20 and the second bracket assembly 30 are driven by the hydraulic control system to move in a direction close to each other or in a direction away from each other. In the embodiment of the present invention, through the coordinated cooperation of the tool seat, the adjustment bracket and the hydraulic control system, firstly, the trumpet-shaped casting is quickly horizontally flipped during the radiographic inspection process, the inspection time is shortened, the difficulty of manual operation is reduced, and the inspection efficiency and the consistency of the inspection film are improved; secondly, the trumpet-shaped casting radiographic inspection tool is adapted to trumpet-shaped castings of different sizes, which improves practical flexibility and extensiveness, and can be applied to the clamping radiographic inspection of various trumpet-shaped castings; finally, the design of the adjustment bracket can avoid scratches and marks on the casting surface during the clamping process, and the structure is reliable and stable.

[0076] In an embodiment of the present invention, the hydraulic control system includes a first hydraulic device 40 and a second hydraulic device 50 which are independent of each other, which may also be referred to as a transverse hydraulic device and a longitudinal hydraulic device. Longitudinal and transverse indicate the placement direction of the hydraulic device relative to the base 12. The first hydraulic device 40 is transmission-connected to the first bracket assembly 20, i.e., a linkage fit. The second hydraulic device 50 is transmission-connected to the second bracket assembly 30, i.e., a linkage fit. The first hydraulic device 40 and the second hydraulic device 50 cooperate with each other mainly to adjust the relative positions of the first bracket assembly 20 and the second bracket assembly 30 for placing trumpet-shaped castings of different calibers and lengths.

[0077] Continue to see Figure 1 As shown, the first hydraulic device 40 is arranged horizontally, and the first hydraulic device 40 includes a first device body 41, a first controller 43 and a first transmission device 44 arranged on the first device body 41. The first bracket assembly 20 is arranged on the first device body 41 through the first transmission device 44, and the first controller 43 controls the first transmission device 44 to move relative to the first device body 41 to drive the first bracket assembly 20 to move toward or away from the second bracket assembly 30. In the embodiment of the present invention, the first controller 43 is used to control the pressure increase and decrease of the first hydraulic device 40, thereby driving the first transmission device 44 to move along the length direction of the first device body 41 and synchronously driving the first bracket assembly 20 to move forward or backward, thereby adjusting the relative position of the first bracket assembly 20 and the second bracket assembly 30.

[0078] In the embodiment of the present invention, the first hydraulic device 40 is connected to the first bracket assembly 20 through the first transmission device 44, thereby driving the first bracket assembly 20 to move. Specifically, the first transmission device 44 connects the first device body 41 and the first support plate 21, and the first support plate 21 is the basis for the transmission connection between the first bracket assembly 20 and the first hydraulic device 40. Specifically, the transmission is realized by engaging the first transmission device 44 disposed above the first device body 41 with the card slot disposed on the bottom side of the first support plate 21, that is, the side away from the support base 23.

[0079] In an embodiment of the present invention, the first device body 41 is in a rectangular parallelepiped shape, and the first device body 41 is horizontally disposed on the base 12 , and can be horizontally fixed to the base 12 using screws, for example, by drilling holes.

[0080] In an embodiment of the present invention, the first support plate is in the shape of a long strip, the width direction of the first support plate 21 is consistent with the length direction of the first device body 41, and the first support plate 21 is arranged on the first device body 41 through a first transmission device. Specifically, the first device body 41 is placed below the first support plate 21 and is located in the middle position. At this time, the two driving wheels 27 arranged on the first support plate 21 are distributed on opposite sides of the first device body 41.

[0081] In the embodiment of the present invention, the first controller 43 is installed on the outside of the first device body 41 for easy operation.

[0082] In an embodiment of the present invention, the outer side surface of the first device body 41 is marked with scale lines 42 for recording the horizontal installation positions of castings of different lengths and calibers on the first device body 41, that is, for recording the corresponding setting positions of the first bracket assembly 20, so as to facilitate the rapid and safe placement of trumpet-shaped castings of different lengths on the tooling, thereby saving operation time and improving detection efficiency.

[0083] Continue to see Figure 1 As shown, the second hydraulic device 50 is vertically arranged. The second hydraulic device 50 has the same working principle as the first hydraulic device 40. The second hydraulic device 50 includes a second device body and a second controller and a second transmission device arranged on the second device body. The second bracket assembly 30 is arranged on the second device body through the second transmission device, and the second transmission device is controlled by the second controller to move relative to the second device body to drive the second bracket assembly to reciprocate in the vertical direction.

[0084] In the embodiment of the present invention, the second hydraulic device 50 is connected to the second bracket assembly 30 through the second transmission device, thereby driving the second bracket assembly 30 to move. Specifically, the second transmission device connects the second device body and the second support plate 31, and the second support plate 31 is the basis for the transmission connection between the second bracket assembly 30 and the second hydraulic device 50. Specifically, the transmission is realized by engaging the card groove arranged on the bottom side of the second support plate 31, that is, the side away from the support frame 33, with the second transmission device arranged on the second device body, so that the second support plate 31 can be raised or lowered to adjust the relative position of the second arc bracket 32 ​​and the first arc bracket 22.

[0085] In the embodiment of the present invention, the second device body is in the shape of a rectangular parallelepiped, and the second device body is vertically arranged on the base 12, and can be fixed on the base 12 by drilling holes and using screws, for example.

[0086] In the embodiment of the present invention, the second support plate 31 is in the shape of a long strip, and the width direction of the second support plate 31 is consistent with the length direction of the second device body.

[0087] In an embodiment of the present invention, the second controller is installed on the outside of the second device body for easy operation.

[0088] In an embodiment of the present invention, the outer side surface of the second device body is marked with scale lines for recording the horizontal installation positions of castings of different lengths and calibers on the second device body, that is, for recording the corresponding setting positions of the second bracket assembly 30, so as to facilitate the rapid and safe placement of trumpet-shaped castings of different lengths on the tooling, thereby saving operation time and improving detection efficiency.

[0089] The present invention also provides a method for radiographic detection of trumpet-shaped castings. The detection method of the present invention is based on the above-mentioned trumpet-shaped casting radiographic detection tooling.

[0090] The method for radiographic detection of trumpet-shaped castings in the present invention is carried out according to the following steps.

[0091] First, move the trumpet-shaped casting X-ray inspection tooling under the overhead crane, and quickly adjust the relative position of the adjustment bracket according to the estimated length of the trumpet-shaped casting to be tested, so as to quickly load the trumpet-shaped casting to be tested.

[0092] Secondly, according to the actual length of the trumpet-shaped casting to be measured, the first bracket assembly and the second bracket assembly are pushed to a preset position by using a hydraulic control system. Specifically, the first hydraulic device is used to drive the first support plate to move relative to the first device body, so as to synchronously drive the first support plate to move toward the direction close to the second bracket assembly, and the second hydraulic device is used to drive the second support plate to move relative to the second device body, so as to synchronously drive the second support plate to move up and down in the vertical direction.

[0093] It should be emphasized that during the first loading of the trumpet-shaped casting to be tested, the second bracket assembly needs to be adjusted and raised to the desired position. Specifically, the second hydraulic device is used to drive the second support plate to move upward along the height direction of the second device body to drive the second arc bracket to move synchronously.

[0094] Then, as the crane gradually descends, the relative positions of the first arc-shaped bracket, the first driving wheel, the first driven wheel and the second arc-shaped bracket, the second driving wheel and the second driven wheel are adjusted to clamp the small-diameter side of the trumpet-shaped casting to be tested on the second bracket assembly, that is, load it on the second arc-shaped bracket and position it between the second driving wheel and the second driven wheel; on this basis, the first hydraulic device and the second hydraulic device are fine-tuned to load the large-diameter side of the trumpet-shaped casting to be tested on the first arc-shaped bracket and position it between the first driving wheel and the first driven wheel.

[0095] Finally, record the positions of the first hydraulic device scale line and the second hydraulic device scale line of this type of trumpet-shaped casting after loading, and mark them on the X-ray detection card; then adjust the casting state by axially and circumferentially rotating the trumpet-shaped casting to be tested, and push the tooling vehicle to the bottom of the X-ray machine probe for radiographic inspection.

[0096] In the embodiment of the present invention, during the X-ray inspection after the tooling vehicle is fixed, after a certain partition position is irradiated, the rotating table can be rotated to drive the casting to rotate axially and irradiate other partition positions to improve the inspection efficiency.

[0097] In an embodiment of the present invention, after the X-ray inspection is completed, the casting is transferred to the positioning and clearing area using a tooling vehicle. After the corresponding casting repair work is completed, it is transferred to the X-ray room for inspection and confirmation. After it is finally qualified, it is transferred to the overhead crane to take out the casting.

[0098] The casting removal process is similar to the loading process. Under the action of the crane, the first hydraulic device is adjusted to remove the large-diameter side of the casting, and the crane is gradually raised to remove the casting. This process reduces manual handling and operation, saves a lot of time, realizes efficient operation of the process line, and greatly improves the inspection efficiency.

[0099] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
