Description

Technical Field

[0001] This application relates to the field of metal casting quality inspection technology, and in particular to a stainless steel metal casting inspection mechanism and inspection method. Background Technology

[0002] Stainless steel castings, with their excellent corrosion resistance and mechanical properties, are widely used in numerous fields such as chemical engineering, aerospace, and medical devices. As industry continues to develop and progress, the requirements for casting quality in various fields are becoming increasingly stringent. High-quality castings can improve product stability and reliability, reduce safety hazards and production failures caused by casting problems, and are of great significance to promoting the development of related industries. In this context, accurate and efficient casting inspection has become a crucial link in ensuring casting quality, and its importance is increasingly prominent.

[0003] In related technologies, such as the Chinese patent with publication number CN119355002A, a laser scanning detection device for metal surface defects is disclosed, which includes a transmission component. The device is characterized by further comprising an extension plate, a stepped track, an adapter slide, an adjustment component, a defect scanning component, a balance box, an air pressure cleaning module, a water gun cleaning module, and a display screen. The bottom two sides of the transmission component are provided with extension plates for supporting the stepped track. The top of the extension plates is provided with a stepped track for sliding the adapter slide. The top of the adapter slide is provided with an adjustment component for raising and lowering the defect scanning component. The outer end of the adjustment component is provided with a defect scanning component for scanning metal surface defects. A balance box is provided above the transmission component, and the outer end of the balance box is provided with a temperature display screen. The balance box is equipped with various cleaning components for cleaning metal surfaces. The air pressure cleaning module and water gun cleaning module are used for stain removal. When using existing laser scanning inspection devices, in laser inspection of metal surfaces, due to differences in metal shape and surface contamination levels, the signal feedback when the laser hits the surface can easily lead to inaccurate detection, requiring repeated adjustments to the detection direction and affecting the overall inspection effect. In contrast, the extension plate, located on both sides of the bottom of the transmission component, can support the stepped track, increasing the working stroke range. The stepped track, located at the top of the extension plate, can adapt to the sliding table, increasing guiding sliding performance. The adjustment component, located at the top of the adapting slide, can drive the defect scanning component to lift and lower. The defect scanning component, located at the outer end of the adjustment component, can be used to scan metal surface defects.

[0004] Regarding the aforementioned technologies, the first and second laser modules of the defect scanning component can only scan the two sides of the casting, and cannot scan the front and back of the casting. The scanning and detection range is limited, which affects the final detection results. Summary of the Invention

[0005] To improve the detection range of casting defects, this application provides a stainless steel metal casting inspection mechanism and inspection method.

[0006] Firstly, this application provides a stainless steel metal casting inspection mechanism, which adopts the following technical solution: A stainless steel metal casting inspection mechanism includes a first support rod, an inspection component, and a transport component. The transport assembly is mounted on the first support rod so that the casting can be transported by the transport assembly; The transport component is provided with a detection component on both sides. The detection component includes a guide rail and a first laser detection unit. The first laser detection unit is mounted on the guide rail through an adjustment component. The adjustment assembly includes a first adjustment rod, which includes a first adjustment section and two second adjustment sections. The first adjustment section is slidably connected to the guide rail along a first direction. The length direction of the first adjustment section is parallel to a second direction, and the second direction is perpendicular to the first direction. The length direction of the second adjustment section is parallel to the first direction. Each end of the first adjustment section is connected to a second adjustment section. A detection area is formed between the first adjustment section and the second adjustment sections. The first laser detection unit is installed on both the first adjustment section and the second adjustment sections, and the first laser detection unit is located on the side closer to the detection area.

[0007] By adopting the above technical solution, a transport component is set up to transport the casting. After the casting is transported between the two first adjusting rods, the transport component stops. The two first adjusting rods slide towards each other along the first direction, so that the two first adjusting rods are located around the casting. The first adjusting rod includes a first adjusting section and a second adjusting section. The first adjusting section is parallel to the second direction and the first adjusting section is parallel to the first direction. That is, the first adjusting section and the second adjusting section can surround the outer periphery of the casting, which can improve the detection range of the first laser detection unit for defects on the outer periphery of the casting. Moreover, the first adjusting section can slide along the first direction, which further improves the detection range of the first laser detection unit for the casting. Depending on the shape and size of the casting, the two first adjusting sections can be moved simultaneously, or one first adjusting rod can be kept stationary while the other first adjusting rod slides along the first direction to achieve the detection of the casting.

[0008] Optionally, the length direction of the guide rail is parallel to the second direction, a first mounting seat is provided between the first adjusting section and the guide rail, the first mounting seat is slidably connected to the guide rail along the second direction, and the first adjusting section is slidably connected to the first mounting seat along the first direction.

[0009] By adopting the above technical solution, in order to further improve the detection range of surface defects of castings, a first mounting seat is provided between the first adjustment section and the guide rail. The first mounting seat is slidably connected to the guide rail along the second direction, driving the first adjustment rod to slide along the second direction, thereby further realizing the sliding of the first laser detection unit on the first adjustment section along the second direction, thereby improving the detection range of casting defects.

[0010] Optionally, a second sliding groove is provided on the side of the first mounting base near the first adjusting section along the first direction, and a second slider is directly or indirectly fixedly connected to the bottom wall of the first adjusting section, and the second slider slides in the second sliding groove along the first direction.

[0011] By adopting the above technical solution, by opening a second groove on the first mounting base, the second slider slides in the second groove, further driving the first adjustment section to slide along the first direction.

[0012] Optionally, it also includes a second drive assembly, which includes a second lead screw and a second motor. The second lead screw is located in the second slide groove and is rotatably connected to the first mounting base. The axis of the second lead screw and its rotation axis are both parallel to the first direction. The second slider is sleeved on the second lead screw and slides along the axis of the second lead screw. The sidewall of the second slider is in contact with the wall of the second slide groove. The housing of the second motor is fixedly connected to the first mounting base, and the output shaft of the second motor is coaxially fixedly connected to the second lead screw.

[0013] By adopting the above technical solution, and by setting a second drive component, the second motor drives the second lead screw to rotate, which in turn drives the second slider to slide along the first direction, and further drives the first adjustment section to slide along the first direction.

[0014] Optionally, the first adjusting section is slidably connected to the first mounting base along a third direction, which is perpendicular to both the first and second directions. A first cylinder is provided between the first adjusting section and the second slider. The cylinder shell of the first cylinder is fixedly connected to the second slider, and the piston rod of the first cylinder is parallel to the third direction and fixedly connected to the first adjusting section.

[0015] By adopting the above technical solution, in order to inspect castings of different heights, a first cylinder is provided between the first adjusting section and the second slider. The first cylinder drives the first adjusting section to slide in a third direction, and drives the first laser detection unit to slide in a third direction, so as to realize the detection along the height direction of the casting.

[0016] Optionally, the adjustment assembly further includes a second adjustment rod and a mounting ring. The second adjustment rod is disposed on a first adjustment section and includes a third adjustment section, a fourth adjustment section, and a fifth adjustment section. The third adjustment section is parallel to a third direction.

The bottom wall of the fourth adjustment section is connected to the fifth adjustment section. The fifth adjustment section is parallel to a third direction. The mounting ring is fixedly connected to the bottom wall of the fifth adjustment section. The mounting ring has multiple second laser detection units spaced apart along its circumference.

[0017] By adopting the above technical solution, and by setting a second adjustment component, a second adjustment rod is set on the first adjustment section, and a plurality of second laser detection units are provided on the mounting ring of the fifth adjustment section. Under the drive of the first cylinder, the second adjustment rod can slide along a third direction, driving the second laser detection units to slide along a third direction. The fifth adjustment section is parallel to the third direction and can penetrate into the inner cavity of the casting to realize the detection of defects in the inner cavity of the casting.

[0018] Optionally, the third adjusting section is rotatably connected to the first adjusting section, and the third adjusting section is parallel to a third direction along the rotation axis of the first adjusting section.

[0019] By adopting the above technical solution, and by setting the third adjustment section to be rotatably connected to the first adjustment section, when the second laser detection unit is not in use, the third adjustment section can be rotated to be parallel to the first adjustment section without affecting the use of the first laser detection unit.

[0020] Optionally, a fourth drive assembly is also included, comprising a drive gear, a driven gear, a connecting rod, and a fourth motor. The top wall of the first adjustment section has a receiving groove for accommodating the fourth drive assembly. The housing of the fourth motor is fixedly connected to the bottom wall of the receiving groove. The drive gear is rotatably connected to the first adjustment section, with its own axis and rotation axis both parallel to a third direction. The output shaft of the fourth motor is coaxially fixedly connected to the drive gear. The driven gear meshes with the drive gear and is rotatably connected to the first adjustment section. The driven gear is connected to the third adjustment section via a connecting rod, the length of which is parallel to a third direction.

[0021] By adopting the above technical solution, a fourth motor is set up. The fourth motor drives the active gear to rotate, which in turn drives the driven gear to rotate, and further drives the third adjusting rod to rotate through the connecting rod.

[0022] Optionally, the third adjustment segment is slidably connected to the first adjustment segment along a third direction; It also includes a fifth drive component for driving the third adjustment segment to slide in a third direction.

[0023] By adopting the above technical solution, the castings have different shapes and sizes. In order to adapt the second laser detection unit to the inner cavity of castings of different heights, a third adjustment section is set to slide along the third direction. The third adjustment section can be adjusted independently in the third direction to meet the detection needs of castings of different heights.

[0024] Secondly, this application also discloses a testing method for a stainless steel metal casting testing organization, comprising the following steps: S1: Transport castings: The casting is transported by a transport assembly. When the casting to be inspected is transported between the two first adjusting rods, the transport assembly stops operating. S2: Start detection: S21: Casting outer surface inspection: The second motor drives the second lead screw to rotate, causing the two first adjusting rods to slide towards each other along the first direction, driving the first cylinder to drive the first adjusting rods to slide from top to bottom along the third direction, and the first laser detection unit on the first adjusting rods to inspect the surface of the casting. S22: Casting internal cavity inspection: If the internal cavity of the casting is to be inspected, the fourth motor is driven, the fourth motor drives the active gear and the driven gear to rotate, and drives the third adjustment section to rotate, so that the second laser detection unit rotates to be aligned with the internal cavity of the casting, drives the first cylinder, and drives the first adjustment rod to slide from top to bottom along the third direction, and the second laser detection unit inspects the internal cavity of the casting. S3: Detection complete. After the inspection is completed, the second motor drives the second lead screw to rotate, causing the two first adjusting rods to slide in the second direction toward the side away from each other. The transport assembly runs and moves the next casting between the two first adjusting rods. Step S2 is repeated until the inspection of all castings is completed.

[0025] By adopting the above technical solution, the casting is transported by a transport assembly. The transport assembly transports the casting to be inspected between two first adjusting rods and then stops operating. A first motor drives the two first adjusting rods to slide towards the side closer to the casting, and a second motor drives the two first adjusting rods to move towards the side closer to the casting along a first direction. A first cylinder drives the first adjusting section to slide along a third direction, thereby driving the first laser detection unit to slide from top to bottom along a third direction. The first laser detection unit inspects the outer surface of the casting. If the casting is a pipe or has an inner cavity, a fourth motor is driven. The fourth motor drives the driving gear and the driven gear to rotate, and further drives the third adjusting section to rotate to the inner cavity position of the casting through the connecting rod. The first cylinder drives the first adjusting rod to slide while simultaneously driving the third adjusting section to slide, which facilitates the second laser detection unit to extend into the inner cavity of the casting for inspection.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. This application, by setting a first adjusting rod, and having a first adjusting section and a second adjusting section that can surround the outer periphery of the casting, can improve the detection range of the first laser detection unit for defects on the outer periphery of the casting. Furthermore, the first adjusting section can slide along a first direction, further improving the detection range of the first laser detection unit for the casting. Depending on the shape and size of the casting, both first adjusting sections can be moved simultaneously, or one first adjusting rod can be kept stationary while the other first adjusting rod slides along the first direction, thereby achieving the detection of the casting. 2. This application sets up a second adjustment component, with a second adjustment rod disposed on the first adjustment section and multiple second laser detection units disposed on the mounting ring of the fifth adjustment section. Under the drive of the first cylinder, the second adjustment rod can slide along a third direction, driving the second laser detection units to slide along a third direction. The fifth adjustment section is parallel to the third direction and can penetrate into the inner cavity of the casting to realize the detection of defects in the inner cavity of the casting. 3. By setting a third adjustment section rotatably connected to the first adjustment section, when the second laser detection unit is not in use, the third adjustment section can be rotated to be parallel to the first adjustment section without affecting the use of the first laser detection unit.

A through hole 4114 is provided through the connecting plate 4112 along the third direction. The screw 91 is rotatably connected to the first adjustment section 411. The screw 91's own axis and rotation axis are both parallel to the third direction. One end of the screw 91 passes through the connecting sleeve 84 and the through hole 4114 in sequence and is then connected to the third adjustment section 461. The adjusting section 461 is fitted with the screw 91 and threadedly connected to the screw 91. The third adjusting section 461 slides along the axis of the screw 91 and can slide within the through hole 4114. The driven gear 82 is fitted with the screw 91. The housing of the fifth motor 93 is fixedly connected to the bottom wall of the second receiving groove 4111. The output shaft of the fifth motor 93 is coaxially fixedly connected to the screw 91. In this embodiment, there are two connecting rods 83. The screw 91 is located on one side between the two connecting rods 83. The connecting rod 83 is a telescopic rod structure. The fixed section of the connecting rod 83 is fixedly connected to the driven gear 82. The movable section of the connecting rod 83 is fixedly connected to the bottom wall of the third adjusting section 461. The fixed section and the movable section of the connecting rod 83 are close to each other and slide together along the third direction. Reference Figure 8 To prevent the driven gear 82 from rotating with the screw 91, a bearing 92 is provided between the driven gear 82 and the screw 91. The bearing 92 is sleeved on the screw 91, and the outer peripheral wall of the bearing 92 is interference-fitted with the inner peripheral wall of the driven gear 82. The inner peripheral wall of the bearing 92 is also interference-fitted with the outer peripheral wall of the screw 91. When the third adjustment section 461 needs to rotate, the fourth motor 85 is driven. The fourth motor 85 drives the driving gear 81 and the driven gear 82 to rotate, and further drives the third adjustment section 461 to rotate through the connecting rod 83. When the third adjustment section 461 needs to slide in a third direction, the fifth motor 93 is driven. The fifth motor 93 drives the screw 91 to rotate, and the screw 91 drives the third adjustment section 461 to slide in a third direction, thereby realizing the sliding of the second laser detection unit 23 in a third direction.

[0042] Reference Figure 4 Before testing, the first cylinder 45 drives the first adjusting rod 41 to slide along the third direction toward the side away from the first mounting base 43. During testing, the first cylinder 45 drives the first adjusting rod 41 to slide along the third direction toward the side closer to the first mounting base 43, so as to realize the testing of the casting from top to bottom.

[0043] It should be noted that the first laser detection unit 22 and the second laser detection unit 23 can perform detection independently or simultaneously, depending on the shape of the casting. The stainless steel metal casting detection mechanism also includes a control system (not shown in the figure). The first laser detection unit 22 is electrically connected to the control system, and the second laser detection unit 23 is electrically connected to the control system, so that the control system controls the first laser detection unit 22 and the second laser detection unit 23 to detect the casting.

[0044] The implementation principle of a stainless steel metal casting inspection mechanism according to an embodiment of this application is as follows: a third motor 71 drives a first rotating shaft 74 to rotate, which drives a pulley 73 and a conveyor roller 32 to rotate, further driving a conveyor belt 31 to transport the casting. The conveyor belt 31 transports the casting to be inspected between two first adjusting rods 41 and then stops running. A first motor 52 drives the two first adjusting rods 41 to slide towards the side closer to the casting. A first cylinder 45 drives a first adjusting section 411 to slide along a third direction, thereby driving a first laser detection unit 22 to slide from top to bottom along a third direction. The first laser detection unit 22 inspects the outer surface of the casting. If the casting is a pipe or has an internal cavity, the fourth motor 85 is driven, which drives the driving gear 81 and the driven gear 82 to rotate. This further drives the third adjusting section 461 to rotate to the position inside the casting cavity via the connecting rod 83. The first cylinder 45 drives the first adjusting rod 41 to slide, which in turn drives the third adjusting section 461 to slide, making it easier for the second laser detection unit 23 to extend into the casting cavity for detection. If the casting cavity is deep, the fifth motor 93 is driven, which drives the screw 91 to rotate. The screw 91 drives the third adjusting section 461 to slide along the third direction, thereby enabling the second laser detection unit 23 to slide along the third direction.

[0045] This embodiment also discloses a testing method for a stainless steel metal casting testing mechanism, including the following steps: S1: Transport castings: The casting is transported by the transport component 3. When the casting to be inspected is transported between the two first adjusting rods 41, the transport component 3 stops operating. S2: Start detection: S21: Casting outer surface inspection: The second motor 62 drives the second lead screw 61 to rotate, causing the two first adjusting rods 41 to slide towards the side that is close to each other along the first direction, driving the first cylinder 45, causing the first adjusting rods 41 to slide from top to bottom along the third direction, and the first laser detection unit 22 on the first adjusting rod 41 to inspect the surface of the casting. S22: Casting internal cavity inspection: If the internal cavity of the casting is to be inspected, the fourth motor 85 is driven, the fourth motor 85 drives the driving gear 81 and the driven gear 82 to rotate, and drives the third adjustment section 461 to rotate, so that the second laser detection unit 23 rotates to be aligned with the internal cavity of the casting, drives the first cylinder 45, and drives the first adjustment rod 41 to slide from top to bottom along the third direction, and the second laser detection unit 23 inspects the internal cavity of the casting; S3: Detection complete. After the inspection is completed, the second motor 62 drives the second lead screw 61 to rotate, causing the two first adjusting rods 41 to slide in the second direction toward the side away from each other. The transport component 3 runs and moves the next casting between the two first adjusting rods 41. Step S2 is repeated until the inspection of all castings is completed.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
