Description

Technical Field

[0001] This invention relates to the field of casting surface treatment technology, and in particular to a device for collecting grinding debris from the shape of wind turbine castings. Background Technology

[0002] In the production of large castings, surface treatment is an indispensable and important step. Among them, grinding aims to remove sprues and burrs, eliminate surface defects such as sand adhesion or oxidation, and improve dimensional accuracy and fit. Grinding is not only for beautifying the appearance, but also a core process to ensure that the casting is dimensionally qualified, eliminate potential failure risks, and create the necessary conditions for subsequent processing or treatment. If the grinding process is skipped, the casting often cannot meet the engineering design and usage requirements.

[0003] Currently, most large castings are formed using resin sand casting, such as wind turbine main shaft products. After initial forming, they still need to undergo a grinding process. However, in the current grinding process of large wind turbine castings, on the one hand, it still relies on manual grinding, which is not efficient. On the other hand, the grinding debris usually flies around randomly and still needs to be cleaned manually. Otherwise, it will affect the grinding of the next workpiece and also affect the grinding efficiency. Therefore, it is necessary to improve the existing technology.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] The following is in conjunction with the appendix Figure 1-5 The technical solution of the present invention will be further illustrated through specific embodiments.

[0054] Please refer to Figure 1 This invention provides a device for collecting grinding debris from wind turbine castings, including a platform 1, a cover device 2, a dust collection mechanism 3, and a grinding mechanism 4.

[0055] The platform 1 is used to place the casting. In addition, the covering device 2 is set in two sets. The covering device 2 can be moved and set on the ground. The two sets of covering devices 2 have a state of being close to each other and joined together, and a state of being far apart from each other and separated.

[0056] When the two sets of enclosure devices 2 are assembled together, the platform 1 and the casting are enclosed in a dustproof cavity that is isolated from the outside world.

[0057] In addition, the dust extraction mechanism 3 is connected to the cover assembly 2 and is used to extract debris located in the dustproof chamber. The polishing mechanism 4 is movably disposed on the cover assembly 2 and is used to polish the casting located in the dustproof chamber.

[0058] In some embodiments, the platform 1 has a flat plate structure and is equipped with a clamp for holding the casting placed on the platform 1 to fix the casting. Optionally, in some specific embodiments, the platform 1 can be fixedly installed on the ground to obtain a firm installation stability. In other specific embodiments, the platform 1 can also be installed on the ground by sliding, which facilitates the transfer of the platform 1 and facilitates assembly line operation.

[0059] It is understood that the specific structure of the fixture is the fixture structure commonly used by those skilled in the art, and will not be described in detail here. In addition, the specific installation method of the shelf 1 can be adjusted according to actual needs, and no restrictions are placed on the specific setting method of the shelf 1 here.

[0060] Based on this, the covering device 2 is located on opposite sides of the platform 1. One side of the covering device 2 has a recessed outline. The two sets of covering devices 2 move along a straight line, and the platform 1 is located on the moving path of the covering device 2. At this time, the covering device 2 has the following movement state:

[0061] In the first state, the two sets of covering devices 2 approach each other. During this process, the two sets of covering devices 2 simultaneously approach the platform 1 and the casting until the two sets of covering devices 2 come into contact with each other. At this time, the recesses on the two sets of platforms 1 are joined together, and the two recesses then form a dustproof cavity, in which the casting is covered.

[0062] In the second state, that is Figure 1 In the displayed state, the two sets of enclosure devices 2 are far apart from each other and simultaneously away from the casting. At this time, the platform 1 is exposed to the outside world. Then the casting can be hoisted onto the platform 1 or taken off the platform 1, thereby realizing the functions of loading and unloading the casting.

[0063] In addition, when the covering device 2 is in the first state, the grinding mechanism 4 can be activated to grind the casting in the dustproof chamber. Although debris will be generated during this process, the debris will accumulate in the dustproof chamber, and the two sets of covering devices 2 prevent the debris from escaping out of the dustproof chamber, thereby achieving the effect of isolating the debris from flying around at will.

[0064] Based on this, after the casting is polished, the dust extraction mechanism 3 will remove the debris inside the dustproof chamber and pack and collect the debris. After most of the debris has been sucked away, the two cover devices 2 will be opened, and the casting will be taken away afterward.

[0065] The wind turbine casting grinding debris collection device provided in this application embodiment allows the grinding mechanism 4 to automatically grind the casting when two sets of enclosure devices 2 are set around it. Under the action of the dust suction mechanism 3, the debris can be sucked away, thereby realizing the automatic cleaning function. In this process, manual intervention can be reduced, and the problem of low efficiency in the grinding process of large wind turbine castings is solved.

[0066] In some embodiments, refer to Figure 2 as well as Figure 3 The two sets of cover-closing devices 2 have the same structure. Here, we will take one set as an example and describe it in detail. Specifically, the cover-closing device 2 includes a first ground rail mechanism 21 and a dust cover 22. The dust cover 22 is disposed on the first ground rail mechanism 21. The first ground rail mechanism 21 is used to drive the dust cover 22 to move back and forth.

[0067] Specifically, the first ground track mechanism 21 includes a first track 211 and a first track flatcar 212. The first track 211 is laid on the ground, and the first track flatcar 212 is installed on the first track 211. The first track 211 provides displacement guidance for the first track flatcar 212, enabling the first track flatcar 212 to reciprocate linearly along the trajectory of the first track 211. It should be explained that the first ground track mechanisms 21 of the two sets of enclosure devices 2 are arranged coaxially, so the two first track flatcars 212 can move on the same straight track.

[0068] Based on this, optionally, the dust cover 22 can be in the shape of a cuboid or a semi-cylindrical shape. The interior of the dust cover 22 is hollow and has an opening on one side, thus forming the concave outline mentioned above. It is understood that the shape of the dust cover 22 can be adjusted according to actual needs, and no specific restrictions are imposed here.

[0069] At this time, the dust cover 22 is fixedly installed on the top of the first track flat car 212. The recess of the dust cover 22 faces the direction of the platform 1, and the recesses of the two sets of cover fitting devices 2 are arranged opposite each other. When the two first track flat cars 212 approach each other, the two dust covers 22 abut against each other and the two recesses are joined together to form a dustproof cavity.

[0070] Based on the above configuration, the first ground rail mechanism 21 can guide the dust cover 22 to move stably. The two dust covers 22 can cover the casting by moving closer and closer together and separating away from each other. The structure is flexible and efficient. When the casting is covered, grinding can be performed. When the dust cover 22 is opened, the casting can be loaded and unloaded to facilitate casting transfer.

[0071] Furthermore, continue to refer to Figure 2 The dust cover 22 is provided with a conical positioning post 221 and a positioning slot 222. The conical positioning post 221 on any dust cover 22 is inserted into the positioning slot 222 on the other dust cover 22.

[0072] Specifically, one end of the conical positioning post 221 is fixedly connected to the side of the recess of the dust cover 22, and the other end of the conical positioning post 221 has a conical profile. In addition, the positioning slot 222 is recessed on the side of the recess of the dust cover 22. The opening size and opening profile of the positioning slot 222 are adapted to the outer profile and outer size of the conical positioning post 221. When the two dust covers 22 approach each other and abut, the conical positioning post 221 is inserted into the positioning slot 222.

[0073] Based on the above configuration, the interlocking of the tapered positioning post 221 and the positioning slot 222 can improve the splicing accuracy between the two dust covers 22, thereby reducing the positional deviation between them, which is beneficial to improving the sealing performance of the dust cover cavity.

[0074] Optionally, the number of mutually cooperating conical positioning posts 221 and positioning slots 222 can be multiple sets, such as ten sets or twenty sets. Multiple sets of mutually cooperating conical positioning posts 221 and positioning slots 222 are arranged at intervals and evenly on the two dust covers 22. At this time, multiple mutually cooperating conical positioning posts 221 and positioning slots 222 can further optimize the fitting accuracy between the two dust covers 22. It is understood that the specific number of conical positioning posts 221 and positioning slots 222 can be adjusted according to actual needs, and no specific limitation is made here.

[0075] Furthermore, it should be added that, in the case of setting multiple sets of conical positioning posts 221 and positioning slots 222, in some embodiments, some of the conical positioning posts 221 can be installed on one of the dust covers 22, and the remaining conical positioning posts 221 can be installed on the other dust cover 22. In this case, a corresponding number of positioning slots 222 can be set on the two dust covers 22, so that the multiple conical positioning posts 221 correspond one-to-one with the multiple positioning slots 222. Alternatively, in other embodiments, all of the multiple conical positioning posts 221 can be installed on one of the dust covers 22, and correspondingly, the multiple positioning slots 222 need to be set on the other dust cover 22, so that the multiple conical positioning posts 221 correspond one-to-one with the multiple positioning slots 222.

[0076] Therefore, regardless of the arrangement of the multiple conical positioning posts 221 and positioning slots 222, the positioning accuracy can be improved by setting the distribution of the conical positioning posts 221 and positioning slots 222. As long as the mutual positioning and cooperation of the two dust covers 22 can be achieved, they should be included in the scope of this solution and no specific restrictions are imposed here.

[0077] Furthermore, referring to Figure 2 and Figure 3 To facilitate the centralized collection of debris, a collection box 23 is provided at the bottom of the covering device 2. The top opening of the collection box 23 is connected to the dustproof chamber. The dust suction mechanism 3 is connected to the collection box 23 and connects to the inside of the collection box 23.

[0078] Specifically, the collection box 23 is fixedly installed at the bottom wall of the recess of the dust cover 22. The inside of the collection box 23 is hollow and the top is open. The collection box 23 is provided with a chip outlet 231. The dust collection mechanism 3 is connected to the chip outlet 231 to draw out the debris inside the collection box 23.

[0079] Based on the above settings, after the polishing work is completed and before the two dust covers 22 are opened, the debris can accumulate at the bottom of the dust chamber under the action of gravity, and further deposit in the collection box 23 through the top opening of the collection box 23. At this time, the dust collection mechanism 3 can be activated to clean the debris in the collection box 23, thereby achieving efficient discharge of debris.

[0080] Furthermore, in some embodiments, the dust collection mechanism 3 includes a fan 31 and a filter box 32.

[0081] The exhaust fan 31 is connected to the filter box 32, the filter box 32 contains a dust collection bag 321, the collection box 23 is provided with a chip outlet 231, and the filter box 32 is connected to the chip outlet 231.

[0082] Specifically, the exhaust fan 31, also known as a side-flow blower or centrifugal blower, can generate a high-speed reverse airflow in a short time to achieve the suction function.

[0083] Based on this, the filter box 32 is hollow inside, and air inlets and outlets (not marked in the figure) are respectively provided on opposite sides. Typically, the filter box 32 is connected to the exhaust fan 31 and the collection box 23 by adding pipes. The pipes responsible for connecting the filter box 32 and the collection box 23 are respectively connected to the dust outlet 231 and the air inlet, and the pipes responsible for connecting the filter box 32 and the exhaust fan 31 are respectively connected to the air outlet and the inlet of the exhaust fan 31, thus realizing the connection between the dust collection mechanism 3 and the cover device 2.

[0084] Based on this, the dust collection bag 321 is installed inside the filter box 32. The dust collection bag 321 can filter and intercept the debris entering the filter box. On the one hand, it can collect the debris, and on the other hand, it can prevent the debris from entering the exhaust fan 31 to avoid damage to the exhaust fan 31.

[0085] Based on the above configuration, the exhaust fan 31 and the filter box 32 can efficiently remove debris from the dustproof chamber, thereby significantly improving the debris cleaning efficiency.

[0086] Furthermore, in some embodiments, the top of the filter box 32 can be set as an open profile, and a cover plate 322 can be detachably installed on its top. In this case, when too much debris accumulates in the dust collection bag 321, the dust collection bag 321 can be disassembled by removing the cover plate 322, and then the debris can be recycled and cleaned. It is understood that the dust collection bag 321 can be installed inside the filter box 32 by a snap-fit ​​structure. The installation methods of the cover plate 322 and the dust collection bag 321 are common installation methods, which will not be described in detail here.

[0087] It should be added that when the dust suction mechanism 3 is sucking up debris in the dustproof chamber, a vent can be opened on the top of the dust cover 22. The vent can maintain the air pressure balance between the inside and outside of the dustproof chamber, so that the airflow can circulate more smoothly in the dustproof chamber, and optimize the overall efficiency of debris suction.

[0088] In addition, in some embodiments, to improve the efficiency of debris removal, the pipe connected to the debris outlet 231 can be extended into the collection box 23, and multiple through holes with an opening size larger than the debris size (not shown in the figure) can be provided through the pipe, which facilitates the cleaning of debris inside the collection box 23.

[0089] Furthermore, referring to Figure 4 The grinding mechanism 4 includes a lifting linear module 41, an angle adjustment module 42, and a grinding component 43.

[0090] The lifting linear module 41 is disposed on the inner wall of the covering device 2, the angle adjustment module 42 is disposed on the lifting linear module 41, the lifting linear module 41 is used to drive the angle adjustment module 42 to move up and down, the grinding component 43 is disposed on the angle adjustment module 42, the angle adjustment module 42 is used to drive the grinding component 43 to move horizontally, and the grinding component 43 is used to grind the surface of the casting.

[0091] In some embodiments, the lifting linear module 41 can be a lead screw linear module or a linear motor module. The specific structures of both the lead screw linear module and the linear motor module are common linear module structures and will not be described in detail here. In this case, by installing the linear lifting module vertically inside the dust cover 22, it can output lifting displacement motion through its slide structure.

[0092] Based on this, the angle adjustment module 42 is installed on the slide of the lifting linear module 41. The grinding component 43 can move linearly or in an arc. In some embodiments, the angle adjustment module 42 can also be a linear module element. The angle adjustment module 42 is used to output horizontal position movement.

[0093] In addition, the grinding component 43 is installed on the lifting linear module 41. The grinding component 43 has a grinding function. At this time, with the joint cooperation of the angle adjustment module 42 and the lifting linear module 41, the grinding component 43 can move up and down and horizontally, thereby changing the grinding position of the grinding component 43.

[0094] Based on the above configuration, with the combined action of the lifting linear module 41, the angle adjustment module 42, and the grinding component 43, grinding operations can be performed on multiple positions of the casting. The structure is flexible and the grinding area is wide, which can meet the actual grinding needs of different castings.

[0095] In some embodiments, refer to Figure 4 and Figure 5 The polishing assembly 43 includes a robotic arm 431 and a polisher 432. The robotic arm 431 is disposed in the angle adjustment module 42, and the polisher 432 is disposed in the robotic arm 431. The robotic arm 431 is used to drive the polisher 432 to move and polish.

[0096] Specifically, the robotic arm 431 can be a six-axis robotic arm 431 device, which has flexible degrees of freedom of movement. In addition, the grinder 432 can be a grinding wheel grinder 432, which can grind the surface of the casting through high-speed rotation.

[0097] Based on the above settings, under the action of the robotic arm 431, the movement range of the polisher 432 can be further increased, thereby enabling the execution of more complex polishing paths and further optimizing and improving the polishing effect.

[0098] In some embodiments, the angle adjustment module 42 includes an arc guide rail 421 and a displacement component 422. The arc guide rail 421 is disposed on the lifting linear module 41, the displacement component 422 is movably disposed on the arc guide rail 421, and the grinding component 43 is disposed on the displacement component 422.

[0099] In wind turbine main shaft castings, which typically have circular or arc-shaped contours, conventional linear modules can only output reciprocating motion, which in turn limits the travel of the grinding component 43.

[0100] Based on this, the arc guide rail 421 is horizontally set and fixedly mounted on the slide of the lifting linear module 41. When the lifting linear module 41 is started, it can drive the arc guide rail 421 to move linearly up and down. In addition, the arc guide rail 421 can further slide and cooperate with the dust cover 22 to improve the load-bearing capacity of the arc guide rail 421. Typically, sliders (not shown in the figure) can be set on both sides of the arc guide rail 421, and a linear guide rail extending vertically is installed on the inner wall of the dust cover 22. By sliding the sliders at the linear guide rail, the arc guide rail 421 can be guided, thereby optimizing and improving the sliding stability and load-bearing capacity of the arc guide rail 421.

[0101] Based on this, the displacement component 422 typically includes a mounting base 4221, a servo motor 4222, and a gear 4223. At this time, an arc rack 4224 extending along its length direction is provided on the arc guide rail 421. The mounting base 4221 is slidably mounted on the arc guide rail 421. Typically, a slider structure can be provided on the mounting base 4221 to slide the slider on the arc guide rail 421, thereby realizing the sliding installation of the mounting base 4221.

[0102] In addition, the servo motor 4222 has the function of outputting positive and negative torque. The servo motor 4222 is fixedly mounted on the mounting base 4221. At the same time, the gear 4223 is fixedly mounted on the output shaft of the servo motor 4222, and the gear 4223 meshes with the arc rack 4224.

[0103] Based on the above settings, by controlling the forward and reverse output torque of the servo motor 4222, the gear 4223 can be driven to rotate in the forward or reverse direction. When the gear 4223 rotates in the forward or reverse direction, it can drive the mounting base 4221 to reciprocate on the arc rack 4224 through cooperation with the arc rack 4224. This allows for flexible adjustment of the position of the grinding component 43. Furthermore, since the movement trajectory of the grinding component 43 is arc-shaped, a larger area of ​​grinding can be performed on the casting.

[0104] It should be added that when the two dust covers 22 are combined, the two grinding mechanisms 4 are located on opposite sides of the casting. At this time, there is a symmetrical central surface (not shown in the figure) between the two grinding mechanisms 4. The concave end face of the dust cover 22 is located on this central surface. Correspondingly, the central surface passes through the casting. At this time, there is a blind area in the area where the central surface intersects with the casting. If the grinding component 43 is moved by linear horizontal displacement, it may be possible that this blind area cannot be ground. Therefore, this solution sets up an arc guide rail 421 and combines the flexibility of the robot arm 431. The two grinding components 43 can grind the blind area alternately, thereby eliminating the obstacle of not being able to grind the blind area of ​​the casting.

[0105] In some alternative implementations, refer to Figure 5 After the polishing process is completed, some debris may fall onto the storage platform 1. To clean the debris more thoroughly, a blower 44 can be installed on the swing arm of the robotic arm 431. The robotic arm 431 can drive the blower 44 toward the storage platform 1, thereby blowing the debris on the storage platform 1 into the collection box 23, which can further improve the degree of debris cleaning.

[0106] Furthermore, to improve the accuracy and automation of the grinding action, the receiving device also includes a camera 5 and a control system. The camera 5 is set on the grinding component 43 to scan the appearance of the casting to obtain three-dimensional mesh data. The control system is connected to the camera 5 and the grinding component 43 respectively. The control system obtains the grinding trajectory based on the three-dimensional mesh data and controls the grinding component 43 to perform grinding through the grinding trajectory.

[0107] Specifically, in some embodiments, the camera 5 may be a CCD scanning camera, which has the function of continuously scanning the outer surface of the casting to form a three-dimensional image, and can calculate and transform the three-dimensional image to obtain three-dimensional mesh data.

[0108] Based on this, the control system typically includes a computer and a PLC controller. The computer and the PLC controller are connected in communication. The computer has processing, analysis and calculation functions, while the PLC controller has the function of performing logic, timing, counting and other operations according to the internally stored program, and then outputting control instructions to the actuator. The computer and the PLC controller are conventional components, and the specific functions and principles of the computer and the PLC controller will not be elaborated here.

[0109] The computer is connected to the CCD scanning camera, and the PLC controller is connected to the CCD scanning camera, the cover assembly 2, the dust collection mechanism 3, and the polishing mechanism 4. The cover assembly 2, the dust collection mechanism 3, and the polishing mechanism 4 can be regarded as specific execution elements.

[0110] The specific polishing control process is as follows:

[0111] S1: When the casting is in place, the user inputs a start command to the computer, the computer sends a start signal to the PLC controller, and the PLC controller sends a closing control signal to the enclosure device 2 based on the start signal, so that the two enclosure devices 2 surround the casting.

[0112] S2: After the two sets of cover-closing devices 2 are closed, the PLC controller sends a scanning control signal to the grinding mechanism 4 and the CCD scanning camera. The grinding mechanism 4 drives the CCD scanning camera to move up and down, and from left and right, so that the CCD scanning camera can obtain the current three-dimensional mesh data of the casting and send the three-dimensional mesh data to the computer.

[0113] S3: The computer uses 3D mesh data as a basis and then compares and analyzes this data with the 3D mesh data of the finished part. During the comparison process, the computer software performs comparison calculations to obtain a non-overlapping 3D graphic contour. Based on this contour, grinding allowance data and grinding path data are generated. Then, this data is sent to the PLC controller. The PLC controller generates a grinding control signal based on the grinding allowance data and grinding path data, and then sends the grinding control signal to the grinding component 43. The grinding component 43 grinds the surface of the casting.

[0114] S4: After polishing is completed, the PLC controller sends a cleaning control signal to the dust collection mechanism 3, which starts and cleans up the debris.

[0115] S4-1: The PLC controller can preset the start-up time of the vacuuming mechanism 3, such as 2 minutes, 3 minutes or 5 minutes, etc., without specific restrictions.

[0116] S4-2: After the polishing step is completed and before the vacuuming mechanism 3 is started, the PLC controller can also send a pre-cleaning signal to the polishing mechanism 4. The polishing mechanism 4 drives the blower 44 to remove the debris on the shelf 1 according to the preset trajectory, so that the debris falls back into the collection box 23. Then, the vacuuming mechanism 3 is started by sending a cleaning control signal to centrally remove the debris in the collection box 23, which can further improve the cleaning effect of the debris.

[0117] S5: After cleaning is completed, the PLC controller sends an opening signal to the two sets of covering devices 2. The two sets of covering devices 2 move away from each other and open, exposing the casting.

[0118] Through the above steps, the automatic grinding and cleaning functions of the castings are realized. The whole process is efficient and fast, and can significantly reduce manual intervention and optimize grinding efficiency.

[0119] Furthermore, looking back Figure 1 and Figure 2 In some embodiments, a second ground track mechanism 6 is also included, with the platform 1 disposed on the second ground track mechanism 6, which passes between two sets of cover devices 2.

[0120] It is understandable that the second ground track mechanism 6 is similar in structure to the first ground track mechanism 21. The second ground track mechanism 6 includes a second track 61 and a second track flatcar 62. The second track 61 is laid on the ground and extends between the two sets of cover devices 2. Furthermore, the second track flatcar 62 is installed on the second track 61. At this time, the platform 1 is installed at the second track flatcar 62.

[0121] Based on the above setup, under the action of the second ground rail mechanism 6, the casting can be automatically driven from a distance to the grinding station, or the casting can be sent from the grinding station to other stations. This can improve the transfer efficiency of the casting and facilitate the automated production line processing of the casting, allowing the casting to have room for further optimization of processing efficiency.

[0122] 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.
