The fixed clamping component includes a clamping seat, a pushing seat, and a position-changing component. Through the cooperation of the clamping seat and the pushing seat, the casting can be quickly fixed and positioned, and the position of the surface of the casting to be detected can be changed through the position-changing component; the detection component includes a detection head one, a detection head two, and a hydraulic cylinder.

[0004] The existing surface damage detection equipment for casting part processing has the following disadvantages when using magnetic particle detection:

[0005] 1. When using magnetic particle detection for the surface damage of cylindrical casting parts, due to the lack of a structure that can be adjusted adaptively in real time according to the shape and size of the cylindrical casting parts, it is impossible to adjust adaptively in real time according to the shape of the cylindrical casting parts, reducing the flexibility of magnetic particle detection for casting parts.

[0006] 2. When using magnetic particle detection for the surface damage of cylindrical casting parts, due to the lack of a powder spraying structure that can fully conform to the shape of the cylindrical casting parts, it is impossible to spray powder evenly on the surface of the cylindrical casting parts, reducing the stability of surface damage detection for cylindrical casting parts. Summary of the Invention

[0007] The purpose of the present invention is directed to an existing surface damage detection device for casting part processing, and its advantages are:

[0008] 1. When using magnetic particle inspection for surface damage of cylindrical castings, the structure of the magnetic particle inspection system can be adjusted in real time according to the size of the cylindrical casting, thereby improving the flexibility of magnetic particle inspection for castings.

[0009] 2. When using magnetic particle inspection for surface damage of cylindrical castings, the powder spraying structure that fully fits the shape of the cylindrical casting can evenly spray powder on the surface of the cylindrical casting, thereby improving the stability of the surface damage inspection of cylindrical castings.

[0010] The above technical objectives of the present invention are achieved through the following technical solutions: A surface damage detection device for casting processing, comprising a positioning mechanism and a detection mechanism, the detection mechanism being arranged on the inner side of the positioning mechanism, the positioning mechanism comprising a supporting assembly, a clamping assembly and an adjusting assembly, the clamping assembly being fixedly connected to the bottom of the inner side of the supporting assembly, the adjusting assembly being arranged at the top of the inner side of the supporting assembly, the detection mechanism comprising an observation assembly, a feeding assembly, a traction assembly, a joint assembly, a magnetic conductive assembly and a powder spraying assembly, the observation assembly being fixedly connected to the bottom of the adjusting assembly, the feeding assembly being clamped on the front side of the observation assembly, the traction assembly being fixedly connected on both sides of the observation assembly, the joint assembly being rotatably connected on both sides of the observation assembly, the magnetic conductive assembly being clamped on the surface of the joint assembly, and the powder spraying assembly being arranged on the inner side of the joint assembly.

[0011] By adopting the above technical solution, a positioning mechanism and a detection mechanism are set up. The positioning mechanism can limit the casting to be inspected and at the same time drive the casting to rotate, so that the detection mechanism can detect surface damage of the casting. The detection mechanism can perform magnetic powder inspection on the casting by adapting to the shape of the casting, and evenly transport the magnetic powder to the surface of the casting. It can also perform comprehensive inspection of the casting through the combination of mechanical vision and magnetic powder, thereby improving the stability of the casting inspection.

[0012] The present invention is further configured as follows: the support assembly includes a connecting base, a supporting frame and an assembly shell, the supporting frame is fixedly connected to the top of the connecting base, and the assembly shell is fixedly connected to the surface of the supporting frame.

[0013] By adopting the above technical solution, by setting up a support component, the connecting base can cooperate with the support frame and the assembly shell, the connecting base can support and limit the support frame and the clamping component as a whole, and the support frame can support and limit the assembly shell and the adjustment component, so that the assembly shell can provide protection for the environment of the detection mechanism for detecting castings, and increase the stability of the detection mechanism when detecting castings.

[0014] The present invention is further configured as follows: The clamping assembly includes a positioning plate, an electric clamp, and an electric rotary clamp head. The positioning plate is fixedly connected to the top of the connection base. The electric clamp is fixedly connected to the top of the positioning plate. The electric rotary clamp head is fixedly connected to the inside of the electric clamp.

[0015] With the above technical solution, by providing the clamping assembly, the positioning plate can cooperate with the electric clamp and the electric rotary clamp head. By limiting the electric clamp through the positioning plate, the electric clamp can drive the electric rotary clamp head to clamp and limit the casting. The electric rotary clamp head can drive the casting to rotate, so as to facilitate the detection mechanism to detect the casting.

[0016] The present invention is further configured as follows: The adjustment assembly includes an electric screw rod, a guiding slider, and an adjustment hydraulic rod. The electric screw rod is fixedly connected to the top inside the support frame. The guiding slider is threadedly connected to the surface of the electric screw rod. The adjustment hydraulic rod is fixedly connected to the bottom of the guiding slider. The top of the guiding slider is slidably connected to the top inside the assembly housing.

[0017] With the above technical solution, by providing the adjustment assembly, the electric screw rod can cooperate with the guiding slider and the adjustment hydraulic rod. By driving the guiding slider to perform reciprocating motion through the electric screw rod, the guiding slider can drive the adjustment hydraulic rod to adjust the orientation. The adjustment hydraulic rod can drive the detection mechanism to move up and down. In cooperation with the guiding slider, the orientation of the detection mechanism can be adjusted to make the detection mechanism adapt to the orientation of the casting and improve the detection accuracy.

[0018] The present invention is further configured as follows: The observation assembly includes a positioning base, a connecting rotating head, and an industrial camera. The positioning base is fixedly connected to the output end at the bottom of the adjustment hydraulic rod. The connecting rotating head is welded to both sides of the positioning base. The industrial camera is arranged at the bottom of the positioning base.

[0019] With the above technical solution, by providing the observation assembly, the positioning base can cooperate with the connecting rotating head and the industrial camera. By supporting and limiting the connecting rotating head and the industrial camera through the positioning base, the connecting rotating head can guide and limit the displacement of the joint assembly. The industrial camera can detect the surface damage of the casting using machine vision.

[0020] The present invention is further configured as follows: The feeding assembly includes a storage box, a feeding pump, and a feeding hose. The storage box is snap-connected to the front side of the positioning base. The feeding pump is connected to the top of the storage box. Two feeding hoses are respectively connected to both sides of the feeding pump.

[0021] By adopting the above technical solution, through setting up a feeding component, the storage box can cooperate with the feeding pump and the feeding hose to store the magnetic powder. The magnetic powder can be transported to the powder spraying component through the feeding hose to provide it with magnetic powder for magnetic powder detection.

[0023] By adopting the above technical solution, through setting up a traction component, the micro winch can cooperate with the guide rope and the positioning pin. By retracting and releasing the guide rope by the micro winch, the guide rope can be adjusted in real time when the positioning pin limits the joint assembly farthest from the connecting rotor, so that the joint assembly as a whole can bend and deform along the guide rope, thereby adapting to the shape of the surface of the casting.

[0024] The present invention is further configured as follows: the joint assembly includes a joint plate, an assembly rotation node and a rope guide groove, the assembly rotation node is rotatably connected to the surface of the connecting head, the joint plate is fixedly connected to the surface of the assembly rotation node, the rope guide groove is opened at the top and bottom of the inner side of the joint plate, and the inner side of the rope guide groove is in contact with the surface of the guide rope.

[0025] By adopting the above technical solution, by setting up a joint assembly, the joint plate can cooperate with the assembly rotation node and the rope guide groove, and the joint plate can be limited by the connection between the assembly rotation node and the connecting rotor, so that the current joint plate can rotate and change the angle with the connecting rotor as the base point, and the current joint plate can be rotatably connected with the assembly rotation node on another identical joint plate, so that the other identical joint plate can rotate and change the angle with the current assembly rotation node as the base point. The rope guide groove can be driven by the guide rope to rotate and change the angle with each assembly rotation node as the guide rope drives the joint plate. Since each joint plate will rotate with its respective assembly rotation node, the first joint plate connected to the connecting rotor will approach or move away from the last joint plate connected to the assembly rotation node. When they are close to each other, the other joint plates will be C-shaped when they rotate with the assembly rotation node, so that they can adapt to the shape of the casting.

[0026] The present invention is further configured as follows: The magnetic conduction component includes an extension rod, a magnetic conduction contact plate, and an electromagnet. The two extension rods are respectively fixedly connected to the front side and the rear side of the joint plate. The magnetic conduction contact plate is fixedly connected to the side of the extension rod away from the joint plate. The electromagnet is fixedly connected to the inner side of the magnetic conduction contact plate.

[0027] With the above technical solution, by setting the magnetic conduction component, the extension rod can cooperate with the magnetic conduction contact plate and the electromagnet. Through the support of the extension rod for the magnetic conduction contact plate, the magnetic conduction contact plate can be kept away from the powder spraying component, thereby avoiding the influence of the magnetic force conducted by the electromagnet and the magnetic conduction contact plate on the casting on the powder spraying component. The electromagnet can conduct the magnetic force to the casting through the magnetic conduction contact plate, so as to use the yoke method for the casting for subsequent magnetic particle inspection.

[0028] The present invention is further configured as follows: The powder spraying component includes a transfer box, a pressure pump, and a powder spraying nozzle. The transfer box is clamped inside the joint plate. The pressure pump is connected to the front side of the transfer box. The front side of the pressure pump is connected to the rear side of the feeding hose. The powder spraying nozzle is connected to the bottom of the transfer box. The bottom of the powder spraying nozzle penetrates through the joint plate and is fixedly connected to the joint plate.

[0029] With the above technical solution, by setting the powder spraying component, the transfer box can cooperate with the pressure pump and the powder spraying nozzle. After the pressure pump pressurizes the magnetic powder conveyed by the feeding hose and conveys it into the transfer box, pressure can be generated in the transfer box, and the transfer box can temporarily store the magnetic powder, so that the powder spraying nozzle sprays the magnetic powder onto the surface of the casting.

[0030] In summary, the present invention has the following beneficial effects:

[0031] 1. By setting the positioning mechanism, the support component can cooperate with the clamping component and the adjustment component. By supporting and limiting the clamping component and the detection mechanism as a whole, a stable damage detection environment can be provided for the detection mechanism. The clamping component can clamp and limit the casting, and can rotate the casting to facilitate the mechanical vision detection of the surface of the casting by the detection mechanism. The adjustment component can drive the detection mechanism to move in different directions, so that the detection mechanism can adapt to the orientation of the casting and detect the casting;

[0032] 2. By setting up a detection mechanism, the observation component can cooperate with the feeding component, the traction component, the arthropod component, the magnetic conduction component, and the powder spraying component. The observation component can detect surface damages of the casting through machine vision. By supporting and limiting the overall structure of the detection mechanism through the observation component, the feeding component can provide magnetic powder for magnetic powder detection to the powder spraying component, limit the basic points of the arthropod component, and let the traction component drive the arthropod component to adjust its orientation, so that the arthropod component changes its shape to adapt to the shape of the casting. The magnetic conduction component can contact the surface of the casting along with the displacement of the arthropod component, thereby guiding the magnetic force to the surface of the casting, providing a prerequisite for the magnetic powder detection of the powder spraying component. By the powder spraying component approaching the casting along with the arthropod component that adapts to the shape of the casting, the magnetic powder can be evenly sprayed onto the surface of the casting, so that the observation component can detect damages based on the distribution state of the magnetic powder on the surface of the casting, improving the flexibility and stability of the surface damage detection of the casting.

[0046] Embodiment 1:

[0047] Refer to Figures 1-5 , a surface damage detection device for casting part processing, including a positioning mechanism 1, the positioning mechanism 1 includes a support assembly 11, a clamping assembly 12 and an adjustment assembly 13, the clamping assembly 12 is fixedly connected to the bottom inside the support assembly 11, and the adjustment assembly 13 is arranged at the top inside the support assembly 11. By setting the positioning mechanism 1, the support assembly 11 can cooperate with the clamping assembly 12 and the adjustment assembly 13. The support assembly 11 can support and limit the whole clamping assembly 12 and the detection mechanism 2, and can provide a stable damage detection environment for the detection mechanism 2. The clamping assembly 12 can clamp and limit the casting part, and can rotate the casting part to facilitate the mechanical vision detection of the surface of the casting part by the detection mechanism 2. The adjustment assembly 13 can drive the detection mechanism 2 to move in different directions, and can make the detection mechanism 2 adapt to the orientation of the casting part and detect the casting part.

[0048] Such as Figure 3As shown, the support assembly 11 includes a connection base 111, a support frame 112, and an assembly housing 113. The support frame 112 is fixedly connected to the top of the connection base 111, and the assembly housing 113 is fixedly connected to the surface of the support frame 112. By providing the support assembly 11, the connection base 111 can cooperate with the support frame 112 and the assembly housing 113. The connection base 111 can support and position the entire support frame 112 and the clamping assembly 12. The support frame 112 can support and position the assembly housing 113 and the adjustment assembly 13. Thus, the assembly housing 113 can protect the environment for the inspection mechanism 2 to inspect the casting, and increase the stability when the inspection mechanism 2 inspects the casting.

[0049] As Figure 4 shown, the clamping assembly 12 includes a positioning plate 121, an electric clamp 122, and an electric rotary clamp head 123. The positioning plate 121 is fixedly connected to the top of the connection base 111, the electric clamp 122 is fixedly connected to the top of the positioning plate 121, and the electric rotary clamp head 123 is fixedly connected to the inside of the electric clamp 122. By providing the clamping assembly 12, the positioning plate 121 can cooperate with the electric clamp 122 and the electric rotary clamp head 123. By limiting the electric clamp 122 through the positioning plate 121, the electric clamp 122 can drive the electric rotary clamp head 123 to clamp and position the casting. The electric rotary clamp head 123 can drive the casting to rotate, thus facilitating the inspection mechanism 2 to inspect the casting.

[0050] As Figure 5 shown, the adjustment assembly 13 includes an electric screw 131, a guiding slider 132, and an adjustment hydraulic rod 133. The electric screw 131 is fixedly connected to the top inside the support frame 112. The guiding slider 132 is threadedly connected to the surface of the electric screw 131. The adjustment hydraulic rod 133 is fixedly connected to the bottom of the guiding slider 132. The top of the guiding slider 132 is slidably connected to the top inside the assembly housing 113. By providing the adjustment assembly 13, the electric screw 131 can cooperate with the guiding slider 132 and the adjustment hydraulic rod 133. By driving the guiding slider 132 to perform a reciprocating motion through the electric screw 131, the guiding slider 132 can drive the adjustment hydraulic rod 133 to adjust its orientation. The adjustment hydraulic rod 133 can drive the inspection mechanism 2 to move up and down. In cooperation with the guiding slider 132, the orientation of the inspection mechanism 2 can be adjusted to make the inspection mechanism 2 adapt to the orientation of the casting and improve the inspection accuracy.

[0051] Brief description of the usage process: First, after connecting the positioning mechanism 1 to the remote control terminal, power it on and start it. The electric fixture 122 will drive the electric rotary fixture head 123 to clamp the casting under the control of the remote control terminal. The electric screw 131 will drive the guiding slider 132 to move the adjusting hydraulic rod 133 to the position where the detection mechanism 2 needs to move under the control of the remote control terminal. The adjusting hydraulic rod 133 will adjust the height of the detection mechanism 2 under the control of the remote control terminal until the detection mechanism 2 reaches the required position. When the detection mechanism 2 performs machine vision detection on the casting, the electric rotary fixture head 123 will drive the casting to rotate under the control of the remote control terminal.

[0052] Embodiment 2:

[0053] Reference Figures 6-11 , a surface damage detection device for casting processing, including a detection mechanism 2. The detection mechanism 2 is arranged inside the positioning mechanism 1. The detection mechanism 2 includes an observation component 21, a feeding component 22, a traction component 23, an articulated component 24, a magnetic conduction component 25, and a powder spraying component 26. The observation component 21 is fixedly connected to the bottom of the adjustment component 13. The feeding component 22 is clamped on the front side of the observation component 21. The traction component 23 is fixedly connected to both sides of the observation component 21. The articulated component 24 is rotatably connected to both sides of the observation component 21. The magnetic conduction component 25 is clamped on the surface of the articulated component 24. The powder spraying component 26 is arranged inside the articulated component 24. By setting the detection mechanism 2, the observation component 21 can cooperate with the feeding component 22, the traction component 23, the articulated component 24, the magnetic conduction component 25, and the powder spraying component 26. The observation component 21 can detect surface damage of the casting through machine vision. By using the observation component 21 to support and limit the overall structure of the detection mechanism 2, the feeding component 22 can provide magnetic powder for magnetic powder detection for the powder spraying component 26, limit the basic points of the articulated component 24, and let the traction component 23 drive the articulated component 24 to adjust its orientation, so that the articulated component 24 changes its shape to adapt to the shape of the casting. The magnetic conduction component 25 can contact the surface of the casting as the articulated component 24 displaces, thereby guiding magnetic force to the surface of the casting, providing a prerequisite for magnetic powder detection by the powder spraying component 26. By making the powder spraying component 26 approach the casting along with the articulated component 24 that adapts to the shape of the casting, magnetic powder can be evenly sprayed onto the surface of the casting, facilitating the observation component 21 to detect damage based on the magnetic powder distribution state on the surface of the casting, improving the flexibility and stability of surface damage detection of the casting.

[0054] Such as Figure 8As shown in the figure, the observation component 21 includes a positioning base 211, a connecting rotating head 212, and an industrial camera 213. The positioning base 211 is fixedly connected to the output end of the bottom of the adjusting hydraulic rod 133. The connecting rotating head 212 is welded on both sides of the positioning base 211. The industrial camera 213 is arranged at the bottom of the positioning base 211. By setting the observation component 21, the positioning base 211 can cooperate with the connecting rotating head 212 and the industrial camera 213. The positioning base 211 supports and limits the connecting rotating head 212 and the industrial camera 213. The connecting rotating head 212 can guide and limit the displacement of the arthropod component 24. The industrial camera 213 can detect the surface damage of the casting by machine vision.

[0055] As Figure 9 shown, the feeding component 22 includes a storage box 221, a feeding pump 222, and a feeding hose 223. The storage box 221 is snap-connected to the front side of the positioning base 211. The feeding pump 222 is connected to the top of the storage box 221. Two feeding hoses 223 are respectively connected to both sides of the feeding pump 222. By setting the feeding component 22, the storage box 221 can cooperate with the feeding pump 222 and the feeding hose 223. The storage box 221 can store magnetic powder, and the magnetic powder can be transported to the powder spraying component 26 through the feeding hose 223 to provide magnetic powder for magnetic powder detection. The feeding pump 222 can be externally connected to a magnetic powder conveying device to supplement magnetic powder to the storage box 221.

[0056] As Figure 9 shown, the traction component 23 includes a micro winch 231, a guiding rope 232, and a positioning pin 233. Four micro winches 231 are respectively fixedly connected to both sides of the top and both sides of the bottom of the positioning base 211. The guiding rope 232 is sleeved on the surface of the micro winch 231. The positioning pin 233 is fixedly connected to the side of the guiding rope 232 away from the micro winch 231. By setting the traction component 23, the micro winch 231 can cooperate with the guiding rope 232 and the positioning pin 233. By winding and unwinding the guiding rope 232 by the micro winch 231, when the guiding rope 232 limits the arthropod component 24 that is farthest from the connecting rotating head 212, the distance between the arthropod component 24 and the connecting rotating head 212 can be adjusted in real time, and the whole arthropod component 24 can be bent along the guiding rope 232, so as to adapt to the shape of the surface of the casting.

[0057] As Figure 10As shown, the arthropod component 24 includes an arthropod plate 241, an assembled rotating node 242, and a rope guiding groove 243. The assembled rotating node 242 is rotatably connected to the surface of the connecting rotating head 212. The arthropod plate 241 is fixedly connected to the surface of the assembled rotating node 242. The rope guiding groove 243 is opened at the top and bottom inside the arthropod plate 241. The inner side of the rope guiding groove 243 is in contact with the surface of the guiding rope 232. By providing the arthropod component 24, the arthropod plate 241 can cooperate with the assembled rotating node 242 and the rope guiding groove 243. Through the connection between the assembled rotating node 242 and the connecting rotating head 212, the arthropod plate 241 can be limited, so that the current arthropod plate 241 can rotate and change the angle with the connecting rotating head 212 as the base point. Moreover, the assembled rotating node 242 on the current arthropod plate 241 can be rotatably connected to the assembled rotating node 242 on another identical arthropod plate 241, so that another identical arthropod plate 241 can rotate and change the angle with the current assembled rotating node 242 as the base point. The rope guiding groove 243 can drive the arthropod plate 241 to rotate and change the angle with each assembled rotating node 242 as the base point by retracting and releasing the guiding rope 232. Since each arthropod plate 241 will rotate with its respective assembled rotating node 242, the first arthropod plate 241 connected to the connecting rotating head 212 will approach or move away from the last arthropod plate 241 connected to the assembled rotating node 242. When approaching each other, when other arthropod plates 241 rotate with the assembled rotating node 242, they will present a C shape, so as to adapt to the shape of the casting.

[0058] As Figure 10 shown, the magnetic conduction component 25 includes an extension rod 251, a magnetic conduction contact plate 252, and an electromagnet 253. The two extension rods 251 are respectively fixedly connected to the front side and the rear side of the arthropod plate 241. The magnetic conduction contact plate 252 is fixedly connected to the side of the extension rod 251 away from the arthropod plate 241. The electromagnet 253 is fixedly connected to the inner side of the magnetic conduction contact plate 252. By providing the magnetic conduction component 25, the extension rod 251 can cooperate with the magnetic conduction contact plate 252 and the electromagnet 253. Through the support of the extension rod 251 for the magnetic conduction contact plate 252, the magnetic conduction contact plate 252 can be kept away from the powder spraying component 26, so as to avoid the influence of the magnetic force conducted by the electromagnet 253 and the magnetic conduction contact plate 252 on the casting on the powder spraying component 26. The electromagnet 253 can conduct the magnetic force to the casting through the magnetic conduction contact plate 252, so as to adopt the magnetic yoke method for the casting to facilitate subsequent magnetic powder inspection.

[0059] As Figure 11As shown in the figure, the powder spraying assembly 26 includes a transfer box 261, a pressure pump 262, and a powder spraying nozzle 263. The transfer box 261 is clamped inside the arthropod plate 241. The pressure pump 262 is connected to the front side of the transfer box 261. The front side of the pressure pump 262 is connected to the rear side of the feeding hose 223. The powder spraying nozzle 263 is connected to the bottom of the transfer box 261. The bottom of the powder spraying nozzle 263 penetrates through the arthropod plate 241 and is fixedly connected to the arthropod plate 241. By setting the powder spraying assembly 26, the transfer box 261 can cooperate with the pressure pump 262 and the powder spraying nozzle 263. After the magnetic powder conveyed by the feeding hose 223 is pressurized by the pressure pump 262, it is conveyed into the transfer box 261, which can generate pressure in the transfer box 261 and temporarily store the magnetic powder in the transfer box 261, so that the powder spraying nozzle 263 sprays the magnetic powder onto the surface of the casting.

[0060] Brief description of the usage process: First, after the detection mechanism 2 is externally connected to the remote control terminal, it is powered on and started. The positioning base 211 will move to the casting under the drive of the positioning mechanism 1. Then, the micro winch 231 will be controlled by the remote control terminal. The micro winch 231 at the bottom will wind up the guiding rope 232, and the micro winch 231 at the top will release the guiding rope 232. The guiding rope 232 at the bottom will drive the positioning pin 233 to pull the arthropod plate 241 farthest from the connecting rotating head 212 towards the connecting rotating head 212. Under the guidance of the guiding rope 232, the rope guiding groove 243 will drive each arthropod plate 241 to expand away from the casting along the assembly rotating node 242 until the arthropod plate 241 and the assembly rotating node 242 form a C shape under the drive of the guiding rope 232 and wrap the casting inside. The magnetic conduction contact plate 252 will contact the surface of the casting. Then, the electromagnet 253 will conduct the magnetic force to the casting through the magnetic conduction contact plate 252 under the control of the remote control terminal. Then, the pressure pump 262 will convey the magnetic powder in the storage box 221 into the transfer box 261 through the feeding hose 223 and pressurize the transfer box 261 under the control of the remote control terminal. The powder spraying nozzle 263 will evenly spray the magnetic powder on the surface of the casting under pressure. The magnetic powder will show the damage on the surface of the casting according to the different magnetic force distributions. At this time, the industrial camera 213 will detect the damage to the distribution state of the magnetic powder on the surface of the casting under the control of the remote control terminal.
