[0062] The present invention will be described in detail below with reference to specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those skilled in the art, several changes and improvements can be made without departing from the scope of the present invention. These all fall within the scope of protection of the present invention.

[0063] Example 1:

[0064] The present invention provides a flexible adaptive magnetic chain tool finishing device, which can perform surface processing on large-volume parts with complex curved surfaces, such as blades of aircraft engines, etc. Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, it includes a supporting tool 1, a magnetic chain tool 3 and a blowing component. The supporting tool 1 is used to fix the workpiece 2 and can drive the workpiece 2 to rotate and / or move in the axial direction; the magnetic chain tool 3 has a processing space 31 and a plurality of magnetic chain blocks 32 arranged in the circumference of the processing space 31 and arranged in sequence along the axial direction of the processing space 31, that is, the processing space 31 is located between the plurality of magnetic chain blocks 32, and abrasive particles 5 are arranged in the processing space 31. The abrasive particles 5 preferably have magnetic particles. The magnetic chain blocks 32 are the magnetic field control source of the abrasive particles 5. The workpiece 2 can enter the processing space 31 under the drive of the supporting tool 1, and the magnetic chain blocks 32 generate magnetic force. Under the control of the magnetic field force formed by the magnetic chain blocks 32, the abrasive particles 5 can be driven to move in an orderly or disordered manner in the processing space 31, thereby performing surface treatment on the workpiece 2. It should be noted that the abrasive particles 5 are controlled by the magnetic field in the processing space 31 and can be arranged along the direction of the magnetic lines of force to form a magnetic abrasive chain soft tool, as shown in FIG. Figure 14 、 Figure 15 、 Figure 16 、 Figure 17 、 Figure 18As shown, when the magnetic chain tool 3 moves and / or the workpiece 2 moves, the workpiece 2 and the magnetic abrasive chain soft tool can produce adaptive processing effects such as scraping and grinding, as shown in FIG. Figure 19 As shown; wherein, each magnetic chain block 32 is able to move along the radial direction of the processing space 31 and / or rotate around the radial direction of the processing space 31, so that the magnetic lines of force of the composite magnetic field formed in the processing space 31 are constantly changing, and the arrangement of the abrasive particles 5 in the processing space 31 is constantly stirred and rolled, thereby achieving a special effect on the surface processing of the workpiece 2.

[0065] The present invention introduces energy through magnetic chains. The external magnetic field can be transmitted to the workpiece 2 through the magnetic chains. The energy changes the strength or stiffness of the magnetic chains, and then changes the degree of interaction with the workpiece 2, reflecting the controllable effect of the end processing effect. During the processing, the magnetic field is first formed by the magnetic chain block 32 to form a complete magnetic chain. The magnetic chain is a linear or densely distributed linear-surface mixed configuration divided by magnetic lines of force. The stronger the external magnetic energy, the denser the distribution. When the workpiece 2 is inserted, the workpiece 2 is in a state of interrupting the magnetic chain. The mutual position and action relationship of the workpiece 2 wrapped by the magnetic chain at the same time, and the abrasive particles 5 are arranged or stirred in the direction of the magnetic chain, thereby achieving the effect of precision processing of the workpiece 2.

[0066] In actual application, the workpiece 2 can be fixed on the supporting tooling 1 in a vertical direction, or the workpiece 2 can be fixed on the supporting tooling 1 at a certain inclination angle to the supporting tooling 1. For the processing method of fixing the workpiece 2 on the supporting tooling 1 at a certain inclination angle, when the supporting tooling 1 drives the workpiece 2 to rotate, the rotation trajectory of the workpiece 2 is conical, which has a disturbing effect on the arrangement of the abrasive particles 5 in the processing space 31, which is beneficial to enhancing the processing effect of the workpiece 2.

[0067] The present invention also provides a flexible adaptive magnetic chain tool finishing method, which controls one or more magnetic chain blocks 32 of the magnetic chain tool 3 to generate magnetic force, thereby driving the abrasive particles 5 to move in an orderly or non-necessary manner in the processing space 31, thereby achieving surface treatment of the workpiece 2 located in the processing space 31; wherein: by driving the workpiece 2 to rotate and / or move axially; and / or driving each magnetic chain block 32 to move in the radial direction of the processing space 31 and / or rotate around the radial direction of the processing space 31, the surface treatment action corresponding to the features of the workpiece 2 is obtained. Because the workpiece 2 and the magnetic chain blocks 32 that generate the magnetic field can both move on their own, the abrasive particles 5 are repeatedly stirred under the drive of various composite forces, so that the present invention can achieve "full feature coverage" adaptive surface treatment of the workpiece 2 with complex free-form surfaces, and can be widely applied to a variety of complex free-form surfaces, such as rotating bodies, non-rotating bodies, etc., to achieve the special effect of integrated deburring, grinding, and polishing.

[0068] Furthermore, while the present invention applies force to the abrasive particles 5 through various complex composite movements, the blowing component in the present invention can spray fluid 4 into the processing space 31. The fluid can be compressed air, etc. The blowing component can also provide power for the movement of the abrasive particles 5 by spraying fluid 4 into the processing space 31 through its own nozzle. By blowing air into the processing space 31 in one direction or multiple directions, the movement trajectory of the abrasive particles 5 can also be changed. The application of the fluid 4 jet force allows the abrasive particles 5 to be surface treated in an environment where the magnetic force and the air blowing force are combined. The movement trajectory of the abrasive particles 5 will be more complex, which is more conducive to the effect of adaptive surface treatment of complex curved surfaces. At the same time, in order to achieve the cleaning of the workpiece 2, after the abrasive particles 5 are polished, some residual particles on the surface or inner cavity of the workpiece 2 can be blown away by the fluid 4 to complete the final cleaning of the workpiece 2, such as Figure 2 、 Figure 3 shown.

[0069] It should be noted that the nozzle on the blowing assembly can be arranged between two adjacent magnetic chain blocks 32, or one or more of the magnetic chain blocks 32 can be replaced with a blowing assembly, which does not affect the movement of the magnetic chain block 32 and can also realize the injection of the fluid 4, so that the abrasive particles 5 can reach a new magnetic chain arrangement under the joint action of the fluid and the magnetic field. Among them, the arrangement of adjacent magnetic chain blocks 32 can be flexibly designed according to actual conditions so that the various components do not interfere with each other when moving.

[0070] In this embodiment, the end of the workpiece 2 is connected to a transition medium, and the support tooling 1 fixes the workpiece 2 through the transition medium. Specifically, the transition medium can be any one of a magnetic part, an adhesive part, an interference fit part, and a clamping part. The workpiece 2 is preferably fixed using a magnetic part, and the workpiece 2 is fixed by magnetic force. For example, the end of the workpiece 2 is connected to a magnetic medium, and the support tooling 1 attracts the magnetic medium by magnetic force to fix the workpiece 2. Specifically, the magnetic medium can be fixed to the end of the workpiece 2 by bonding, which can reduce local wear or damage to the workpiece 2 caused by being fixed. The workpiece 2 can also be fixed by directly bonding it to the support tooling 1. In addition, the workpiece 2 can also be fixed by an interference fit part or a clamping part. For example, the transition medium is a structure that can achieve an interference fit with the workpiece 2, and the end of the workpiece 2 can be interference-fitted inside the transition medium to achieve fixation. The clamping parts can be mechanically clamped (such as clamping by a robot), clamped by shape memory alloy deformation or expansion deformation (clamping and fixing is achieved by causing the clamping part to expand and contract due to temperature changes), clamped by phase change material (a combination of more than one phase change material, which deforms due to temperature changes, such as paraffin, etc.), metal clamping (low-melting point liquid metal is heated and solidified for clamping, such as tin, lead, gallium, etc.), and frozen connection (low-temperature freezing connects the two parts together), all of which can achieve the effect of stable fixation of the workpiece 2.

[0071] Specifically, the magnetic chain block 32 is preferably an electromagnetic induction structure, mainly composed of an electromagnetic coil, and by passing different types and sizes of current through the magnetic chain block 32, the magnetic chain block 32 can provide at least one of a bias magnetic field, an alternating magnetic field, and a pulsed magnetic field, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, the actual processing requirements of the workpiece 2 are met.

[0072] The present invention also provides a motion platform, including a flexible adaptive magnetic chain tool finishing device and a control unit, wherein the magnetic chain tool 3 is configured to be arranged in sequence, and the multiple magnetic chain tools 3 can be switched in various forms, for example, by switching the position of the magnetic chain tool 3 in the form of a chain or a conveyor belt to enable the workpiece 2 to be processed by different magnetic chain tools 3. That is to say, the present invention can match the corresponding magnetic chain tool 3 according to the characteristics of the workpiece 2 for surface treatment, wherein the multiple magnetic chain tools 3 are all in different tool forms; and / or the multiple magnetic chain tools 3 have different types of abrasives 5, for example, the number of magnetic chain blocks 32 in the magnetic chain tool 3 is different, and the particle size of the abrasive particles 5 is different; for another example, the volume of the magnetic chain blocks 32 is different, and the proportion of the number of different particle sizes in the abrasive particles 5 is different; for another example, the size of the processing space 31 in the magnetic chain tool 3 is different, etc.

[0073] During the processing, the characteristic information of the workpiece 2 is input into the control software of the control unit in advance. Then, during processing, the control unit can control the movement of the matching magnetic chain block 32 and / or control the excitation current of the input magnetic chain block 32 according to the characteristic information of the workpiece 2 to achieve surface treatment of the workpiece 2. By controlling the movement of the magnetic chain block 32 and / or controlling the excitation current of the input magnetic chain block 32, the strength and arrangement shape of the magnetic chain formed by the abrasive particles 5 can be changed to meet the needs of workpieces 2 with different shapes, such as Figure 20 To achieve uniform surface removal of the workpiece 2, after extracting feature information, the rotation and vibration of the workpiece 2 and the coupling control of the magnetic chain tool 3 are used to achieve "full feature coverage" processing of complex free-form surface parts, simultaneously removing burrs and grinding and polishing the surface or cavities of the workpiece 2.

[0074] Specifically, if Figure 6 、 Figure 7 、 Figure 8 As shown, the supporting tooling 1 includes a plurality of parallel robotic arms 11, a base 12, a rotary lifting mechanism 13 arranged on the base, and a connecting position 14 at the end of the rotary lifting mechanism 13. The end of the workpiece 2 is fixed on the connecting position 14. During processing, the telescopic action of the plurality of parallel robotic arms 11, the rotation and up and down movements of the rotary lifting mechanism 13 can drive the workpiece 2 to rotate, move axially, and torsionally, so that the workpiece 2 inserted into the interior of the magnetic chain tool 3 is surface-treated. The magnetic chain tool 3 can reciprocate through the conveyor belt to adjust the position of the magnetic chain tool 3, so as to transport the magnetic chain tool 3 matching the workpiece 2 to the bottom of the workpiece 2, so that the workpiece 2 can be inserted into the interior of the magnetic chain tool 3 for surface treatment.

[0075] More specifically, the abrasive particles 5 are preferably constrained to a closed or semi-closed processing space 31. In this embodiment, a left support plate 33 and a right support plate 34 are respectively provided on both sides of the processing space 31. A bellows 35 is provided between the left support plate 33 and the right support plate 34. The left support plate 33, the right support plate 34 and the bellows 35 together form a semi-closed processing space 31. Through holes are provided on the left support plate 33 and the right support plate 34. The magnetic chain blocks 32 are respectively provided on the through holes of the two support plates. The upper end of the bellows 35 has an opening for the workpiece 2 to enter and exit the processing space 31. Through the above structure, the surface processing of the workpiece 2 is achieved by controlling the movement of the workpiece 2 and / or controlling the movement of the magnetic chain block 32 and applying an excitation current.

[0076] Example 2:

[0077] This embodiment is a variation of Embodiment 1.

[0078] In this embodiment, the magnetic chain blocks 32 are all permanent magnets, such as Figure 12 As shown, the magnetic field strength of the processing space 31 is changed by controlling the distance between the permanent magnets, thereby changing the arrangement and strength of the magnetic chain structure formed by the abrasive particles 5.

[0079] Furthermore, the magnetic chain cutter 3 can also be designed as a combination of permanent magnets and high magnetic permeability materials, that is, a part of the magnetic chain blocks 32 are made of permanent magnets, and the other part of the magnetic chain blocks are made of high magnetic permeability materials, such as Figure 13 、 Figure 15 、 Figure 18 As shown, the effect of magnetic chain processing in the present invention can also be achieved.

[0080] like Figure 5 As shown, the magnetic chain block 32 is capable of torsional swinging. The magnetic chain block 32 can be configured as a combination of an electromagnetic coil and a swing shaft. By changing the current passed into the electromagnetic coil to change the strength of the magnetic field, etc., the swing shaft can be controlled to swing or move in the axial direction through a power mechanism such as a motor.

[0081] Example 3:

[0082] This embodiment is another variation of Embodiment 1.

[0083] This embodiment provides a motion platform, the workpiece 2 is fixed on the platform, and the supporting tool 1 has three sliding support components, each sliding support component includes a vertical slide 15 and a sliding table 16 that can slide up and down on the vertical slide 15, each sliding table 16 is connected to the base 12 through two robot arms 11, and the magnetic chain tool 3 is directly fixed to the lower end of the rotating lifting mechanism 13. The robot arm 11 can be retracted and retracted through pneumatic control or hydraulic control to adjust the posture of the magnetic chain tool 3. At the same time, the rotating lifting mechanism 13 can control the magnetic chain tool 3 to rotate or move up and down, and control the magnetic chain tool 3 to move downward so that the workpiece 2 fixed at the bottom enters the processing space 31. By controlling the action of the magnetic chain block 32 and applying an excitation current, the workpiece 2 is surface-treated in the processing space 31, such as Figure 11 As shown, this embodiment adopts a method in which the workpiece 2 is fixed and the magnetic chain tool 3 moves as a whole, thereby achieving a high-efficiency surface processing effect.

[0084] by Figure 8 For example, the working principle of the present invention is as follows:

[0085] According to the characteristics of the workpiece 2, the characteristic information of the workpiece 2 is first input into the control software of the control unit in advance. When the processing operation starts, the control unit first controls the conveyor belt to transport the magnetic chain tool 3 matching the workpiece 2 to the bottom of the workpiece 2 according to the characteristic information. At this time, multiple parallel robot arms 11 work together to transport the workpiece 2 located on the connection position 14 to the processing space 31. At this time, the rotary lifting mechanism 13 drives the workpiece 2 to move up and down and / or rotate, or drives the workpiece 2 to only twist and swing through multiple parallel robot arms 11. Some or all of the magnetic chain blocks 32 in the magnetic chain tool 3 are energized to generate a magnetic field, which in turn drives the abrasive particles 5 to move to form a magnetic chain soft tool, thereby performing surface treatment on the workpiece 2. At the same time, according to the processing requirements, some or all of the magnetic chain blocks 32 can be controlled to rotate around the axis and / or reciprocate along the axis direction at the same time to realize the construction and transformation adjustment of the corresponding magnetic field force, thereby realizing special surface treatment action on the workpiece 2.
