Description

Technical Field

[0001] This invention relates to the field of casting forming technology, and in particular to a large casting gantry machining system. Background Technology

[0002] Large castings are widely used in key sectors of the national economy, such as aerospace, wind power, shipbuilding, and heavy machinery. With the rapid development of advanced forming technologies such as integrated die casting, the size of large castings is constantly increasing and their structure is becoming more complex, which puts forward higher requirements for subsequent machining accuracy. Gantry machining centers, with their high structural rigidity, good working stability, and high machining accuracy, have become the core equipment for precision machining of large castings.

[0003] In gantry machining systems for large castings, the workpiece is usually placed on a pit-type worktable structure. This pit arrangement can reduce the overall height of the machining system and enhance the static and dynamic rigidity of the machine tool, which plays an important role in ensuring the machining accuracy of large-sized workpieces.

[0004] However, the pit structure also presents challenges for process inspection and maintenance. The machining cycle for large castings is typically long, requiring thorough checks of workpiece surface quality, dimensional accuracy, tool condition, and machining allowance distribution to determine if the machining meets process requirements and whether adjustments to machining parameters or compensation are necessary. However, the pit's confined space and limited access routes pose a risk of falls from heights when personnel climb ladders. Furthermore, the pit bottom is often slippery due to cutting fluid and chips, increasing the risk of falls and serious injuries. Additionally, prolonged downtime for inspections severely impacts machining efficiency and accuracy.

[0005] In summary, existing large casting gantry machining systems still rely on manual shutdown and pit operation for inspection during the machining process, which poses significant safety hazards and efficiency bottlenecks. Therefore, it is necessary to improve the existing technology.

[0006] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Summary of the Invention

[0023] The first mounting part is rotatably connected to the gantry machining center, and the lifting linear module is disposed in the first mounting part;

[0024] The second mounting part is connected to the lifting linear module. When the mounting part is flipped to the underside of the crossbeam of the gantry machining center, the lifting linear module is used to drive the second mounting part to reciprocate up and down.

[0042] Compared with the prior art, the present invention has the following beneficial effects:

[0043] The large casting gantry machining system provided by this invention allows for the activation of a tilting mechanism when the machining status of a workpiece needs to be inspected. This tilts the mounting section down and brings it closer to the top of the workpiece. At this time, a cleaning mechanism can be activated to remove debris from the top of the workpiece. Subsequently, a camera mechanism is used to observe the machining status of the top of the workpiece in real time. After the inspection is completed, the tilting mechanism is activated again to move the cleaning mechanism and the camera mechanism away from the workpiece, and the gantry machining center continues machining. This process achieves safer inspection without the need for personnel to participate. Furthermore, the entire process can be started promptly after the tool stops machining and can resume machining immediately after the inspection is completed. This significantly shortens downtime and improves inspection efficiency. The significant safety hazards and efficiency bottlenecks in operation inspection are solved and optimized.

[0061] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0062] In the description of this invention, it should be understood that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component present simultaneously. When a component is considered to be "set" on another component, it can be directly set on the other component or there may be an intermediate component present simultaneously.

[0063] Furthermore, terms such as “long,” “short,” “inner,” and “outer” indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings. They are used only for the purpose of describing the present invention and are not intended to indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientational configuration. Therefore, they should not be construed as limitations of the present invention.

[0064] The following is in conjunction with the appendix Figure 1-4 The technical solution of the present invention will be further illustrated through specific embodiments.

[0065] Please refer to Figure 1 , 2 as well as Figure 3 This invention provides a large casting gantry machining system, including a ground rail device 1, a gantry machining center 2, a tilting mechanism 3, a cleaning mechanism 4, and a camera mechanism 5.

[0066] The system includes a ground rail device 1 located outside the pit, a gantry machining center 2 located on the ground rail device 1, which drives the gantry machining center 2 to move back and forth. The gantry machining center 2 is used to process the top of the workpiece placed on the ground rail. A flipping mechanism 3 is located on the gantry machining center 2 and can flip up and down along a vertical plane. The flipping mechanism 3 is equipped with a mounting part, which includes at least two states: flipped to below the crossbeam of the gantry machining center 2 and flipped away from the bottom of the gantry machining center 2. A cleaning mechanism 4 is located on the mounting part. When the mounting part flips to below the crossbeam of the gantry machining center 2, the cleaning mechanism 4 is used to clean the debris on the top of the workpiece. A camera mechanism 5 is located on the mounting part. When the mounting part flips to below the crossbeam of the gantry machining center 2, the camera mechanism 5 is used to acquire a real-time image of the top of the workpiece.

[0067] In some large castings, such as the main shaft of wind power equipment, the structure is usually quite long. Therefore, it is necessary to set up a pit on the ground and set up a platform in the pit to place the casting on the platform by hoisting.

[0068] At this time, the ground rail device 1 is set on the ground near the pit. The ground rail device 1 usually includes a guide rail and a power component. The guide rail is laid on the ground, and the gantry machining center 2 is slidably installed on the guide rail. The power component is installed on the gantry machining center 2. Usually, the power component includes a motor and gears. The gears are installed on the output shaft of the motor, and a rack is set on the guide rail. The gears and racks mesh. By starting the motor, the gears rotate. With the cooperation of the gears and racks, the gantry machining center 2 can be pushed to move along the guide rail, thereby realizing position adjustment. For ease of understanding, a three-dimensional coordinate system is selected as a reference, including three directions: x, y, and z. The x and y directions are horizontal, and the z-axis direction is vertical. The gantry machining center 2 moves back and forth along the x-axis direction.

[0069] In some specific embodiments, the gantry machining center 2 typically has a gantry frame structure, which includes two legs and a crossbeam disposed between the two legs. Based on this, to further ensure that the gantry machining center 2 can move stably, the guide rails and power components can be configured as two sets. The guide rails are arranged on both sides of the pit and are parallel to each other. The two legs of the gantry frame are slidably disposed on the two guide rails. Correspondingly, the two sets of power components are disposed on the two legs. At this time, by activating the two sets of power components simultaneously, both sides of the gantry frame can be subjected to thrust, the gantry frame is force-balanced, and the translation is stable.

[0070] In addition, a spindle mechanism 7 is also provided on the crossbeam of the gantry machining center 2. The spindle mechanism 7 can obtain motion degrees of freedom from the y-axis and z-axis by adding a linear module. At this time, with the cooperation of the power unit and the linear module, the spindle mechanism 7 can move along the x-axis, y-axis and z-axis in three-dimensional space. The spindle mechanism 7 can be equipped with milling cutters or boring cutters. At this time, the machining path can be preset in the PLC control system or CNC control system to realize automated milling or automated boring of the top of the casting.

[0071] It is understandable that the specific installation method and working principle of the gantry machining center 2 are not the key to this solution, so its specific working principle will not be elaborated here.

[0072] Furthermore, the main spindle mechanism 7 is located on one side of the crossbeam, while the flipping mechanism 3 is located on the opposite side of the crossbeam. This avoids interference between the flipping mechanism 3 and the main spindle mechanism 7. At this time, a vertical plane (not shown in the figure) is selected along the direction perpendicular to the y-axis and coinciding with the z-axis. The flipping mechanism 3 flips within this vertical plane. Based on this, the flipping mechanism 3 has two states:

[0073] In the first state, the flipping mechanism 3 flips to the underside of the crossbeam. At this time, the cleaning mechanism 4 and the camera mechanism 5 can face the top of the workpiece. The cleaning mechanism 4 is used to clean the debris on the top of the workpiece so as to obtain a clearer real-time image of the top of the workpiece.

[0074] It should be explained that before the flipping mechanism 3 flips to the underside of the crossbeam, the spindle mechanism 7 can be driven to move along the y-axis to one side of the machining center, which can further avoid structural interference.

[0075] In the second state, the flipping mechanism 3 flips to a position away from below the gantry machining center 2, which can also be understood as flipping to above the crossbeam. At this time, it can drive the spindle mechanism 7 to return to its original position and continue machining.

[0076] The implementation principle of the large casting gantry machining system provided in this application embodiment is as follows: When it is necessary to check the machining status of the workpiece, the flipping mechanism 3 can be activated to flip the mounting part down and get close to the top of the workpiece. At this time, the camera mechanism 5 and the cleaning mechanism 4 rely on the displacement function of the gantry machining center 2 in the x-axis direction to make the camera mechanism 5 and the cleaning mechanism 4 face the part of the workpiece that needs to be observed, so as to ensure that the cleaning and imaging actions have good accuracy.

[0077] Subsequently, the cleaning mechanism 4 can be activated to clean the debris on the top of the workpiece. Then, the processing status of the top of the workpiece can be observed in real time through the camera mechanism 5 to check the current processing status. If there is a problem, the processing plan can be adjusted. If there is no problem, the flipping mechanism 3 can be activated again to move the cleaning mechanism 4 and the camera mechanism 5 away from the workpiece, thereby avoiding structural interference, and the gantry machining center 2 can continue processing.

[0078] The above process requires no human intervention and can be started immediately after the tool stops machining. It can also record the previous tool body coordinates and resume machining immediately after inspection, significantly shortening downtime and improving inspection efficiency.

[0079] Furthermore, in some embodiments, reference is made to Figure 2 as well as Figure 3 The flipping mechanism 3 includes a frame 31, a power component 32, and a rotating component 33.

[0080] The frame 31 is rotatably mounted on the crossbeam of the gantry machining center 2. The power assembly 32 is mounted on the gantry machining center 2 and connected to the frame 31. The power assembly 32 is used to drive the frame 31 to rotate. The rotating assembly 33 is mounted on the frame 31 and forms the mounting part. The cleaning mechanism 4 and the camera mechanism 5 are both mounted on the rotating assembly 33. The rotating assembly 33 is used to drive the camera mechanism 5 and the cleaning mechanism 4 to rotate along the circumferential direction of the workpiece.

[0081] It should be explained that the circumferential rotation of the workpiece can be understood as driving the camera mechanism 5 to rotate around the z-axis.

[0082] Based on the above settings, by setting the rotating component 33 as the mounting part, on the one hand, it provides installation space for the cleaning mechanism 4 and the camera mechanism 5, and on the other hand, it can change the cleaning angle of the cleaning mechanism 4, increase the cleaning range of debris, and increase the shooting range of the camera mechanism 5, so as to observe a larger workpiece processing surface.

[0083] In some specific embodiments, refer to Figure 3To enable the frame 31 to be rotatably installed, a hinge seat 21 is provided at the crossbeam of the gantry machining center 2. The frame 31 is provided with a rotating shaft (not marked in the figure), and the rotating shaft is rotatably connected to the hinge seat 21.

[0084] Specifically, there are two hinge seats 21, which are fixedly installed on the crossbeam. At the same time, the rotating shaft is fixedly installed on the frame 31. The rotating shaft is parallel to the y-axis, and the two ends of the rotating shaft are rotatably installed on the two hinge seats 21 through bearings.

[0085] Based on the above configuration, under the guidance of the hinge seat 21 and the rotating shaft, the frame 31 can flip up and down in the vertical plane, thereby realizing the position change of the flipping mechanism 3 and the cleaning mechanism 4.

[0086] Furthermore, in some embodiments, the hinge seat 21 is provided with an arc-shaped positioning groove 211, and the frame 31 is provided with a limiting block 301 that slides in the arc-shaped positioning groove 211. When the limiting block 301 abuts against one end of the arc-shaped positioning groove 211, the flipping mechanism 3 and the cleaning mechanism 4 flip to the underside of the crossbeam of the gantry machining center 2 and face the workpiece in the vertical direction.

[0087] Specifically, the arc-shaped positioning groove 211 is recessed on the side surface of the hinge seat 21 near the frame 31, and it is semi-circular. One end of the arc-shaped positioning groove 211 is located directly above the other end, and the two are on the same vertical line. The center of the arc-shaped positioning groove 211 coincides with the rotation center of the rotating shaft. At the same time, the limiting block 301 is fixedly installed on the frame 31. The limiting block 301 is inserted into the arc-shaped positioning groove 211, and the limiting block 301 slides and abuts against the inner wall of the arc-shaped positioning groove 211.

[0088] At this point, the process of the frame 31 flipping up and down includes at least two states:

[0089] In the first state, the limiting block 301 abuts against the upper inner wall of the arc-shaped positioning groove 211. At this time, the frame 31 is in an upward flipping state, which can drive the cleaning mechanism 4 and the camera mechanism 5 away from the working main shaft mechanism 7 to avoid structural interference.

[0090] In the second state, the limiting block 301 abuts against the lower inner wall of the arc-shaped positioning groove 211. At this time, the frame 31 is in a downward flipping state, which can drive the cleaning mechanism 4 and the camera mechanism 5 to approach the product, thereby realizing the observation of the processed surface.

[0091] Based on the above settings, with the combined action of the limiting block 301 and the arc-shaped positioning groove 211, the flipping action of the frame 31 can be guided to make it more stable. On the other hand, the flipping angle of the frame 31 can be positioned to prevent the frame 31 from flipping too much and colliding with the crossbeam. When the frame 31 flips up and down, it can abut against the end of the arc-shaped positioning groove 211, which can also enable the camera mechanism 5 and the cleaning mechanism 4 to obtain precise positioning and maintain a vertical neutral position, making it convenient to observe the processing area of ​​the workpiece.

[0092] Furthermore, referring to Figure 3 The power assembly 32 includes a drive motor 321 and a reducer 322. The drive motor 321 is mounted on the crossbeam of the gantry machining center 2, and the reducer 322 is mounted on the crossbeam of the gantry machining center 2. It has an output shaft and an input shaft. The input shaft of the reducer 322 is connected to the output shaft of the drive motor 321, and the output shaft of the reducer 322 is connected to the rotating shaft.

[0093] Specifically, the drive motor 321 can be a servo motor or a three-phase asynchronous motor, etc., with a motor structure that can stably output torque. No specific restrictions are made here. The drive motor 321 is fixedly mounted on the hinge base 21, and the reducer 322 is also fixedly mounted on the hinge base 21. At the same time, the input shaft of the reducer 322 is connected to the output shaft of the drive motor 321 through a coupling, and the output shaft of the reducer 322 is connected to the rotating shaft through a coupling.

[0094] Based on the above settings, the drive motor 321 can continuously output torque. On this basis, the torque can be increased by the reducer 322, and the power transmission can be made more stable. As a result, the frame 31 can drive the cleaning mechanism 4 and the camera mechanism 5 to rotate smoothly, and the structural stability is optimized and improved.

[0095] In some embodiments, refer to Figure 3 The rotating component 33 includes a rotating bracket 331 and a rotating motor 332.

[0096] The rotating bracket 331 is rotatably mounted on the frame 31. The cleaning mechanism 4 and the camera mechanism 5 are both mounted on the rotating bracket 331. The rotating motor 332 is mounted on the frame 31 and connected to the rotating bracket 331, and is used to drive the frame 31 to rotate, thereby driving the cleaning mechanism 4 and the camera mechanism 5 to rotate.

[0097] Specifically, the rotation axis of the rotating bracket 331 is selected as I. When the rotating component 33 is flipped to the second state described above, the rotation axis I coincides with the z-axis. Typically, a bearing seat is provided on the frame 31. The rotating bracket 331 has a column structure, and a turntable is provided at one end of the column. The column part of the rotating bracket 331 is rotatably mounted on the bearing seat and rotates along the I-axis. In addition, the cleaning mechanism 4 and the camera mechanism 5 are respectively installed at the turntable. When the column rotates, the turntable synchronously drives the cleaning mechanism 4 and the camera mechanism 5 to rotate.

[0098] Meanwhile, the rotary motor 332 can be a servo motor or a three-phase asynchronous motor or other motor components that can continuously output torque. No specific restrictions are made here. The rotary motor 332 is fixedly installed on the frame 31, and the output shaft of the rotary motor 332 is connected to the column of the rotary support 331 through a coupling. At this time, starting the rotary motor 332 can drive the rotary support 331 to rotate.

[0099] Based on the above configuration, the rotating bracket 331 can provide the cleaning mechanism 4 and the camera mechanism 5 with the freedom of rotational movement, and its plate part provides the installation space for the cleaning mechanism 4 and the camera mechanism 5. At this time, by starting the rotating motor 332, the cleaning mechanism 4 and the camera mechanism 5 can be driven to rotate along the z-axis and I-axis through the plate, thereby expanding the cleaning position and the camera range.

[0100] Furthermore, the disk body can adopt a disc structure, and its center line coincides with the I-axis. In this case, the cleaning mechanism 4 and the camera mechanism 5 set on the disc can be installed in the middle of the disc, or they can be installed in other parts near the edge and off-center from the center line. No matter where they are set, the cleaning mechanism 4 and the camera mechanism 5 can move smoothly along a fixed trajectory and reduce the risk of collision interference of the structure.

[0101] Different casting products typically have different height dimensions. If the casting is too tall, it may cause structural interference between the flipping mechanism 3 and the casting. If the casting is too short, when the flipping mechanism 3 flips to the underside of the crossbeam, the camera mechanism 5 and the cleaning mechanism 4 will be too far away from the product, resulting in unclear images and inadequate debris cleaning.

[0102] Based on this, in some embodiments, the rotating component 33 further includes a lifting linear module 333, while the frame 31 includes a first mounting part 311 and a second mounting part 312.

[0103] The first mounting part 311 is rotatably connected to the gantry machining center 2. The lifting linear module 333 is disposed on the first mounting part 311. The second mounting part 312 is connected to the lifting linear module 333. When the mounting part is flipped to the underside of the crossbeam of the gantry machining center 2, the lifting linear module 333 is used to drive the second mounting part 312 to reciprocate up and down. The rotating component 33 is disposed on the second mounting part 312.

[0104] Specifically, both the first mounting part 311 and the second mounting part 312 are plate-shaped structures. The aforementioned rotating shaft is fixedly mounted on the second mounting part 312. The second mounting part 312 is rotatably mounted on the crossbeam via the rotating shaft. Meanwhile, the lifting linear module 333 uses a linear motor module or a lead screw linear module, etc. Its specific principles and structure will not be elaborated here. The linear motor is fixedly mounted on the second mounting part 312, and its motion output direction is consistent with the I-axis direction.

[0105] Meanwhile, the first mounting part 311 and the second mounting part 312 are parallel. The first mounting part 311 is fixedly mounted on the slide of the lifting linear module 333. At the same time, the column of the rotating bracket 331 is rotatably mounted on the first mounting part 311 through the bearing seat, and the rotating motor 332 is also mounted on the first mounting part 311.

[0106] Based on the above settings, by activating the lifting linear module 333, the first mounting part 311 can be driven to move the rotating component 33 back and forth along the I-axis, thereby changing the extension length of the cleaning mechanism 4 and the camera mechanism 5. At this time, when the height of the workpiece is too large, the first mounting part 311 can be driven to move away from the workpiece, thereby avoiding structural collision and interference. When the height of the workpiece is too small, the first mounting part 311 can be driven to move closer to the workpiece, thereby reducing the impact on image clarity and debris cleaning effect.

[0107] Furthermore, referring to Figure 3 The cleaning mechanism 4 includes a blower 41 and a nozzle component 42.

[0108] The blower 41 is disposed on the rotating assembly 33, and the nozzle component 42 is disposed on the rotating assembly 33 and connected to the blower 41. The blower 41 applies airflow to the workpiece for cleaning debris via the nozzle component 42.

[0109] Specifically, the blower 41 is fixedly installed on the disc of the rotating assembly 33. The blower 41 is provided with an air outlet, and a pipe is connected to the air outlet. At the same time, the nozzle component 42 is fixedly installed on the disc, which has an airflow channel inside and is connected to the pipe. It should be explained that a clearance hole can be opened on the disc to facilitate the installation of the pipe. At this time, the high-speed airflow generated by the blower 41 can be guided into the airflow channel through the pipe and sprayed out from the nozzle component 42 onto the surface of the workpiece.

[0110] Based on the above configuration, the blower 41 can generate a high-speed airflow, which is precisely applied to the surface of the workpiece via the nozzle component 42, thereby blowing away the debris attached to the surface of the casting and efficiently cleaning the debris on the workpiece surface to obtain a clearer image.

[0111] Furthermore, the nozzle component 42 includes a first nozzle portion 421 and a second nozzle portion 422.

[0112] The first air nozzle 421 is located on the rotation center I of the mounting part. The first air nozzle 421 is connected to the blower 41 and is provided with a first air duct. The second air nozzle 422 is connected to the first air nozzle 421 and is provided with a second air duct connected to the first air duct.

[0113] When the flipping mechanism 3 moves to below the crossbeam of the gantry machining center 2, the first air duct is vertically positioned and opposite to the workpiece. At the same time, the first air duct is tilted and opposite to the workpiece.

[0114] Specifically, the first air nozzle 421 and the second air nozzle 422 are both circular pipe outlines. The first air duct runs through both ends of the first air nozzle 421, and the second air duct runs through both ends of the second air nozzle 422. One end of the second air nozzle 422 is connected to the first air nozzle 421 and is inclined relative to the first air nozzle 421. At this time, the first air nozzle 421 and the second air nozzle 422 form a Y shape, and the first air duct and the second air duct are connected. The first air duct and the second air duct constitute the airflow channel mentioned above.

[0115] In addition, the center line of the first air nozzle 421 coincides with the I-axis. At this time, when the rotating bracket 331 rotates, the first air nozzle 421 rotates on its own axis, while the second air nozzle 422 rotates eccentrically along the I-axis.

[0116] Based on the above configuration, the airflow entering the first air duct can be blown out directly from the first air duct, while another part of the airflow can also enter the second air duct and be blown out through the air duct. At this time, since the first air nozzle 421 coincides with the I-axis, part of the airflow will be blown vertically from top to bottom onto the workpiece, thereby blowing the debris to the surroundings. At this time, combined with the rotating support 331, the second air nozzle 422 swings eccentrically, driving another part of the airflow to be rotated and sent out onto the workpiece, thereby further blowing the blown debris toward the periphery of the workpiece, thereby achieving a more thorough and comprehensive debris cleaning, which helps to prevent debris from obstructing the working surface of the workpiece.

[0117] Furthermore, referring to Figure 3 as well as Figure 4 The camera mechanism 5 includes a camera module 51 and an angle adjustment component 52.

[0118] The camera module 51 is rotatably mounted on the flip mechanism 3, and the angle adjustment component 52 is mounted on the flip mechanism 3 and connected to the camera module 51 to drive the camera module 51 to swing up and down.

[0119] Specifically, the camera module 51 can be a CCD camera module 51, which is connected to the control system of the processing center through a signal line, and uses the processing chip in the control system to process the image signal to realize the real-time acquisition of image signal on the display screen. It is understood that the specific working principle of the camera module 51 is not the focus of this solution, so it will not be elaborated on.

[0120] Based on this, the camera module 51 is mounted on the edge of the disk of the rotating bracket 331. Typically, a lens bracket can be set on the disk. The camera module 51 is rotated and mounted on the lens bracket using a turntable structure (not shown in the figure). At this time, the lens of the camera module 51 faces the workpiece, and the turntable can guide the camera module 51 to swing up and down in the working state.

[0121] Meanwhile, the angle adjustment component 52 can be a motor component, which is mounted on the lens bracket and its drive shaft is fixedly connected to the turntable. By activating the angle adjustment component, the turntable can be driven to rotate, thereby driving the camera module 51 to swing up and down and change the observation angle.

[0122] Based on the above configuration, on the one hand, by placing the camera module 51 on the edge of the disk, the camera module 51 can be moved around the workpiece when the disk rotates, thereby obtaining a larger shooting area and more comprehensively acquiring the processing status of the workpiece. At the same time, by activating the angle adjustment component 52, the tilt angle of the camera module 51 can be adjusted, thereby changing its observation position, which can increase the shooting area and facilitate capturing more precise image area positions, significantly improving the image acquisition effect.

[0123] Furthermore, the camera module 5 also includes a fill light 6, which is disposed in the camera module 51 and is used to illuminate the inspection area of ​​the camera module 51.

[0124] Based on the above settings, the supplementary light 6 can supplement light in workshops with insufficient light, thereby obtaining clearer image information, which is convenient for operators or systems to make judgments.

[0125] It should be explained that the flipping mechanism 3, cleaning mechanism 4, and gantry machining center 2 in this solution are all controlled by a control system, such as a PLC control system. The PLC control system is connected to the host computer, and operation instructions are input through the host computer. The PLC control system realizes the automatic coordination of each component through preset programming. Since the automatic coordination of each component is not the focus of this solution, its specific control principle will not be elaborated.

[0126] The working principle of the large casting gantry machining system provided in this application is as follows:

[0127] The gantry machining center 2 first performs milling on the workpiece located in the pit. After the machining step is completed, such as the roughing step, the host computer sends an operation command. The PLC control system sends a displacement command to the spindle mechanism 7 according to the preset programming, and drives the spindle mechanism 7 to move to one side of the gantry to avoid interference. The interference referred to here includes the interference between the tilting mechanism 3, the cleaning mechanism 4 and the camera mechanism 5 and the spindle mechanism 7, as well as the interference between the spindle mechanism 7 itself and the workpiece. Then, a tilting command is sent to the tilting mechanism 3. The tilting mechanism 3 responds to the tilting command and drives the cleaning mechanism 4 and the camera mechanism 5 to tilt from top to bottom to below the crossbeam.

[0128] After the flipping action is completed, the PLC control system continues to send displacement commands to the ground rail device 1 and the lifting linear module 333. The ground rail device 1 drives the cleaning mechanism 4 and the camera module 5 to move laterally via the crossbeam and the flipping mechanism 3, while the lifting linear module 333 drives the cleaning mechanism 4 and the camera module 5 to move up and down, so that the cleaning mechanism 4 and the camera module 5 move to a suitable position above the workpiece.

[0129] Next, the PLC control system sends work instructions to the cleaning mechanism 4 and the rotating component 33. The rotating component 33 drives the cleaning mechanism 4 to rotate, and at the same time, the cleaning mechanism 4 cleans the debris on the surface of the workpiece. Meanwhile, the camera mechanism 5 acquires real-time image information of the top of the workpiece and sends the signal to the host computer via wireless or wired transmission. The host computer can process and analyze the image signal and convert it into an image so that the operator can observe the processing status. The operator can then perform the next instruction operation based on the processing status, realizing remote inspection. The safety hazards of the inspection are significantly reduced, and the efficiency bottleneck caused by the inspection operation is broken through.

[0130] Therefore, the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
