[0002] When we pick up stones and shells on the beach, we often see stones and shells washed into various shapes by sea water and sand. We can't help but marvel at the magical power of nature.

[0049] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments 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 of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0050] The present invention provides a round-edge tool, such as Figure 2As shown, it includes a unit body 1, and the number of the unit bodies 1 is one or more. Under the drive of external force, one or more of the unit bodies 1 can move in an orderly manner or without moving along the to-be-processed part on the workpiece 2, thereby realizing the processing of the to-be-processed part on the workpiece 2. The unit body 1 can adopt a variety of shapes, such as granular, polyhedral, spherical, nanoparticles, micro-nanoparticles, permanent magnet particles, permanent magnet particles, etc. The unit body 1 includes regular structures and / or irregular structures. The regular structures are fixed shapes and can be repeatedly processed in industry according to their appearances, such as spheres, prism structures, frustum structures, pyramid structures and cylindrical structures. The irregular structures can adopt polyhedral structures, such as gemstone structure particles, sand grains, metal grains, which can be naturally formed structures or processed structures. In practical applications, there are a variety of materials to choose from, such as iron pins that appear in machining, and fine sand, which can be selected in specific applications.

[0051] In practical applications, the unit body 1 can be a geometric body with regular or random edges, such as the unit body 1 having regular edges, irregular edges, random edges, etc., or a geometric body with arc segments, arcs or full circles. At the same time, the unit body 1 can be made of naturally formed particles or obtained by machining. When machining is used, the structure can be selected as an integral molding or a split part, for example, the split part adopts a structure in which metal is embedded in solid particles. The unit body 1 can also be an inclusion, such as one component is wrapped around the outside of another component, such as Fig.14 As shown, the unit body 1 is wrapped with an insulating layer on the outside and is an electrostatic body with positive or negative charge on the inside. The unit body 1 can be moved by applying an external electric field, thereby realizing the processing of the workpiece 2.

[0052] The processing of the workpiece 2 by the unit body 1 described in the present invention is preferably performed by using multiple unit bodies 1. The multiple unit bodies 1 or the workpiece 2 apply energy to make the unit body 1 and the workpiece 2 contact and implement static and dynamic alternation, dynamic contact pressing, scraping, local edge cutting (or random cutting), tumbling (different edges) cutting, vibration impact and other processing operations, thereby forming a collection or cluster effect. In actual processing, multiple unit bodies 1 form more than one edge cutting edge, forming a collective cutting tool or a cluster cutting tool (group blade or group blade tool), that is, more than one unit body 1 acts on the workpiece 2, and realizes multiple accumulations, alternating accumulations, and multiple accumulations of the micro-friction processing effects of each unit body 1 on the workpiece 2, thereby achieving a processing process from micro-accumulation to macro-qualitative change, and finally achieving the processing effect of the to-be-processed part of the workpiece 2.

[0053] Specifically, the hardness or rigidity and material of the unit body 1 can be configured according to the type of the workpiece 2. For example, if the workpiece 2 is made of manganese steel, the unit body 1 can be made of a metal material with higher hardness.

[0054] In the actual processing operation of the present invention, auxiliary medium 3 can also be added to meet the needs of different processing methods. The auxiliary medium 3 is used to cooperate with the relative movement or restraining movement of the unit body 1 when processing the workpiece 2, so as to match the properties of different workpieces 2 or different processed parts. The auxiliary medium 3 is solid, liquid or a solid-liquid mixture, such as glue, to glue the unit bodies 1 together, such as Fig.10 As shown, the unit bodies 1 that are glued together are restrained by each other when moving due to the presence of glue, and can move within a certain range. The distance between adjacent unit bodies 1 can only move within a small range due to the glue bonding, thereby achieving specific processing of the workpiece 2; the auxiliary medium 3 can also be a liquid, such as water, electrorheological fluid; a solid-liquid mixture, such as magnetorheological fluid.

[0055] Furthermore, the auxiliary medium 3 can also adopt a structure that relies on electric field control, such as a composite structure in which a first component wraps a second component, the second component carries a positive charge or a negative charge of a certain polarity, and the first component is an uncharged insulator. In practical applications, an electric field is applied externally to form an electric field control based on the auxiliary medium as a thrust, thereby realizing the processing operation of the unit body 1 on the workpiece 2.

[0056] The present invention also provides a processing device, using the group-edge tool, such as Figure 1 , Figures 4 to 13 As shown, it includes a support body 4, and the unit body 1 is installed on the support body 4, wherein the unit body 1 can be installed around the support body 4 or inside the support body 4. In a preferred example, a first accommodating space 5 is provided on the support body 4, and the unit body 1 is installed in the first accommodating space 5. The processing equipment in the present invention can realize the processing of the workpiece 2 by driving the workpiece 2 to move or driving the unit body 1 to move, wherein when the workpiece 2 is processed by driving the workpiece 2 to move, the unit body 1 moves with the workpiece 2, forming a synchronous movement, an asynchronous movement, and a combination of synchronous and asynchronous movement of the unit body 1 and the workpiece 2, thereby improving the processing efficiency.

[0057] Furthermore, in a preferred example, a through opening 6 is provided on the support body 4, and the workpiece 2 or the part to be processed of the workpiece 2 can enter the first accommodating space 5 through the through opening 6. In actual applications, the support body 4 can adopt a rigid structure or a flexible structure. When a flexible structure is adopted, the support body 4 can drive the unit body 1 to process the workpiece 2 by driving itself to deform. Specifically, driving the workpiece 2 to move or driving the unit body 1 to move can adopt any one or more of the driving modes of motor drive, magnetic drive, phase change material drive, negative pressure drive, cylinder drive, hydraulic cylinder drive, intelligent material drive, thermal expansion drive, cold contraction drive, and electrostatic force drive.

[0058] The self-deformation method mentioned in the present invention is that the spatial shape of the support body 4 can be deformed by applying energy, including a variety of optional methods:

[0059] Passive deformation: self-elasticity or interactive deformation with the wrapped object.

[0060] Vibration deformation: deformation caused by external energy applied through force conduction or displacement conduction:

[0061] Adaptive deformation: The force, displacement or frequency caused by increasing external applied energy is optimally deformed according to the needs of the surrounded object (such as the workpiece).

[0062] In the present invention, the deformation of the support body 4 itself can also be a combination of the above multiple deformation driving modes.

[0063] In the present invention, more than one unit body 1 or working object can implement overall motion control, thereby enhancing the relative motion, containment and tumbling effect of the micro unit body 1 and the working object, and between the units.

[0064] The basic embodiments of the present invention are described above. The working principle of the present invention is further described below through specific embodiments.

[0065] In the embodiment, the workpiece 2 is a sword, wherein one end of the sword is a special-shaped structure formed by a plurality of protrusions and grooves, wherein the part to be processed of the sword has holes in multiple directions, which has been initially formed after lathe processing, but the inner surfaces of the plurality of protrusions, grooves and holes are difficult to be fine-processed by lathe. The present invention is now used to achieve fine processing of the plurality of grooves and protrusion structures of the sword.

[0066] Embodiment 1:

[0067] like Figure 5As shown, the support body 4 is a prismatic structure or a cylindrical structure with one side being an open end, the first accommodating space 5 is connected to the outside through the open end, a pusher 7 and a driver 8 are arranged on the support body 4, wherein the pusher 7 can move along the axial direction of the support body 4 under the drive of the driver 8, the driver 8 adopts a magnetostrictive material in the smart material, and controls the expansion and contraction of the driver 8 by applying a magnetic field to the driver 8, thereby exerting a force on the pusher 7, the unit body 1 is a collection of granular bodies made of ferromagnetic material, the pusher 7 and the open end of the support body 4 form an open accommodating chamber, the unit body 1 is installed in the accommodating chamber and part of the unit body 1 extends to the outside of the accommodating chamber as shown in FIG. Figure 4 As shown, since the unit body 1 is made of ferromagnetic material, when the support body 4 is magnetized, the unit body 1 can gather in the accommodating chamber or around the accommodating chamber without separation, and can make creeping motion under the push of the pusher 7. During the processing, the support body 4 is fixed, and the sword is rotated at the same time. By applying a magnetic field to the driving body 8 and then controlling the movement of the pusher 7, the unit body 1 and the sword can be more closely fitted. The friction cutting of the protrusions and grooves of the sword is realized by the friction cutting of multiple unit body 1 particles and the sword. Since the unit body 1 particles are small in size relative to the processing part, the finishing of the processing surface can be realized through frequent scraping, grinding and other processing. The present invention can also process the workpiece 2 and the support body 4 in a way that the workpiece 2 and the support body 4 act simultaneously during processing, which can be flexibly set according to the actual processing scene.

[0068] Embodiment 2:

[0069] like Figure 6 , Figure 7 As shown, the open end of the support body 4 is provided with a through hole 6, and the through hole 6 adopts a flexible opening and is a structure made of rubber with a certain elasticity. The support body 4 is a prismatic structure or a cylindrical structure. The end of the workpiece 2 to be processed is inserted into the first accommodating space 5 in the support body 4 through the through hole 6. When the workpiece 2 is inserted into the first accommodating space 5, the through hole 6 can support and fit tightly against the circumference of the workpiece 2 due to its own elasticity, thereby preventing the unit body 1 from moving to the outside of the support body 4 through the through hole 6 during the processing operation.

[0070] Furthermore, if Fig.14 As shown, the through opening 6 is a circular structure composed of eight sector-shaped rubber plates 9, and the arc part is connected to the support body 4. During processing, the support body 4 is kept fixed, and the workpiece 2 can be rotated or dragged to make relative friction movement between the workpiece 2 and the unit body 1, thereby realizing the processing of the workpiece 2. In different application scenarios, the support body 4 can be placed in different ways to complete the processing of the workpiece 2, such as Figure 7 As shown, the opening is toward the side.

[0071] In actual processing, when the support body 4 adopts a flexible structure, such as a flexible capsule, an external force can be used to drive the support body 4 to deform so as to move the unit body 1, such as Figure 8 , Fig. 9 As shown, the unit body 1 and the workpiece 2 undergo relative friction motion to complete the processing of the workpiece 2.

[0072] Embodiment 3:

[0073] In actual processing operations, the support body 4 can adopt a split structure. For example, the support body 4 includes multiple boundary bodies, each of which is equipped with the unit body 1. When processing the workpiece 2, it can be achieved by driving the multiple boundary bodies to move and / or driving the workpiece 2 to move.

[0074] Specifically, Fig.10 As shown, the support body 4 includes a first boundary body 10 and a second boundary body 11. The first boundary body 10 is provided with a second accommodating space 12, and the second boundary body 11 is provided with a third accommodating space 13. The first boundary body 10 and the second boundary body 11 are opened relative to each other and can move relative to or away from each other.

[0075] Furthermore, if Fig.10 , Fig.11 As shown, the unit body 1 is installed in the second accommodating space 12 by means of magnetism, and the mixture of the unit body 1 and glue is installed in the third accommodating space 13. The mixture of glue and the unit body 1 can not only realize the movement of the unit body 1, but also enable multiple unit bodies 1 to move within a certain range or move relative to each other within a certain range. By placing the workpiece 2 between the first boundary body 10 and the second boundary body 11 and rotating the workpiece 2 at a certain speed, the first boundary body 10 and the second boundary body 11 are driven to move closer, so that the workpiece 2 can be processed. The processing or local processing of specific parts of the workpiece 2 can be achieved, which is more targeted and particularly suitable for scenes where the workpiece 2 is large in size. In practical applications, the support body 4 can be designed as a combination of two or more parts to achieve fine processing of large-volume workpieces 2.

[0076] Specifically, when the support body 4 adopts a split structure, it can realize simultaneous processing of multiple workpieces 2, or simultaneous processing of multiple parts of the same workpiece 2, and can be flexibly designed according to actual processing scenarios to meet actual processing needs.

[0077] In the present invention, the processing of the workpiece 2 can also be assisted by adding water, magnetorheological fluid, electrorheological fluid, nanoparticle fluid and other media in the first accommodating space 5 to achieve a better processing effect. At the same time, the driving force can be achieved by high-pressure blowing, fluid blowing, high-pressure suction, fluid suction and a combination of blowing and suction.

[0078] like Fig.12 , Fig.13 As shown, Fig.13 The holes and other parts in the workpiece 2 can also be fine-processed. The left and right sides of the support body 4 are respectively connected to fluid pipelines. Through the inflow and outflow or suction operation of the fluid, the fluid drives the unit body 1 to move frictionally in the holes to be processed in the workpiece 2, thereby realizing the processing of special parts.

[0080] The above describes the specific embodiments of the present invention. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art can make various changes or modifications within the scope of the claims, which does not affect the essence of the present invention.
