Description

Technical Field

[0001] The present application belongs to the technical field of polishing equipment, and in particular relates to a software-driven nozzle adjustment device for abrasive water jet polishing. Background Art

[0002] Abrasive water jet polishing technology is a precision machining technology with the advantages of a wide range of machining materials, no thermal processing effects, and the ability to meet the high shape accuracy and high surface roughness requirements of nonlinear and complex curved parts. This technology uses a high-speed spray of polishing liquid mixed with fine abrasive particles to act on the workpiece surface, and removes materials through the high-speed collision and shearing effect of the abrasive particles. It is a polishing process that quantitatively corrects the surface roughness of the workpiece by controlling the process parameters such as pressure, angle and spray time of the polishing liquid spray.

[0003] However, when using abrasive water jet polishing technology to polish parts with cavity structures such as hydraulic valve bodies and pump casings, especially when polishing cavity structures with smaller structural dimensions, the water jet nozzle can only be inserted into the cavity due to the small cavity space and complex structure. This requires manual adjustment of the water jet nozzle when polishing the cavity, which affects the polishing efficiency of the cavity and increases the workload of the staff. At the same time, when manually adjusting the water jet nozzle, there is a defect of poor adjustment accuracy, which in turn affects the polishing quality of the cavity. Summary of the invention

[0004] The present application provides a software-driven nozzle adjustment device for abrasive water jet polishing, so as to improve the polishing efficiency of the inner surface of a cavity, reduce the workload of the staff and improve the polishing quality of the cavity.

[0005] The technical solution adopted in this application is:

[0006] A software-driven nozzle adjustment device for abrasive water jet polishing, comprising:

[0007] A driving section, at least two of which are provided, each of which comprises a base, a moving body and a driving member for driving the moving body to move toward or away from the base;

[0008] A flexible connection sleeve, which is arranged between two adjacent driving joints, and two ends of the flexible connection sleeve are respectively fixedly connected to the base body and the moving body;

[0009] A nozzle, which is detachably connected to the moving body at the end so as to follow the movement of the moving body at the end;

[0010] An abrasive hose, which is passed through the flexible connecting sleeve and the driving joint and one end of which is connected to the nozzle;

[0011] A plurality of flexible adjustment wires are arranged along the circumference of the driving section, each of the flexible adjustment wires is passed through a plurality of the driving sections, and each of the flexible adjustment wires has a stop end that cooperates with the moving body stop located at the end.

[0012] By adopting the above technical solution, when the soft-driven nozzle adjustment device in the present application is used to polish the inner surface of the cavity, first select a suitable number of drive sections according to the length of the cavity, and then assemble the soft-driven nozzle adjustment device according to the selected number of drive sections, so that the nozzle is installed on the moving body located at the end, one end of the abrasive hose is connected to the nozzle, and then the end of the flexible adjustment wire away from the stop end is connected to the winding device, the other end of the abrasive hose is connected to the abrasive supply device, and the base located at the end is connected to the abrasive supply device or the winding device, so that the abrasive supply device or the winding device supports the base located at the end ; Then the soft-driven nozzle adjustment device is extended into the cavity that needs to be polished. When the soft-driven nozzle adjustment device is extended into the cavity, the winding device winds up the flexible adjustment wire on the corresponding side according to the shape of the cavity, and the two adjacent driving sections move relative to each other under the action of the flexible adjustment wire, so that an angle matching the cavity is formed between the two adjacent driving sections, so that the nozzle moves to the position where the cavity needs to be polished; when the nozzle moves to the position where the cavity needs to be polished, the abrasive supply device transports the polishing abrasive into the abrasive hose, so that the polishing abrasive is ejected from the nozzle after passing through the abrasive hose to realize the polishing operation of the cavity.

[0013] When adjusting the polishing position, the driving member is started, and the driving member drives and adjusts the moving body to move the moving body relative to the base, so that the moving body drives the nozzle to move to the next position required for polishing. During this process, no staff operation is required, and the entire process is automatically operated, thereby improving the polishing efficiency of the cavity, reducing the workload of the staff, and ensuring the accuracy of the nozzle position adjustment, thereby improving the polishing quality of the cavity.

[0014] When the flexible adjusting wire is wound up, the flexible connecting sleeve will be deformed under the action of the driving joint and bend toward the side where the wound flexible adjusting wire is located, so that when the wound flexible adjusting wire is unwound, the two adjacent driving joints can move toward the coaxial position under the action of the flexible connecting sleeve, so that when the flexible adjusting wire on the other side is wound up, the flexible connecting sleeve can also bend toward the other side under the action of the driving joint, so that the two adjacent driving joints form an angle on the other side, so that the soft-driven nozzle adjustment device can enter the cavity for polishing operation, and at the same time, it can also adjust the nozzle in a cavity with multiple bends, and adjust the erosion polishing angle of the abrasive water jet through the adjusting wire, so as to greatly improve the polishing efficiency and polishing quality of the cavity.

[0015] In addition, since the nozzle is detachably connected to the moving body at the end, a suitable nozzle can be selected according to the shape of the cavity to increase the flexibility of the software-driven nozzle adjustment device and improve the polishing quality of the cavity using the software-driven nozzle adjustment device.

[0016] Optionally, the driving member includes an electromagnet provided on one of the base and the moving body, a matching piece provided on the other of the two and having ferromagnetism, and an elastic part provided between the base and the moving body. When the electromagnet is in an energized state, the electromagnet generates a magnetic attraction on the matching piece so that the moving body overcomes the elasticity of the elastic part and moves toward a direction close to the base.

[0017] By adopting the above technical solution, when the electromagnet is powered on, the electromagnet generates a magnetic field and generates a magnetic attraction to the matching piece, so that the moving body overcomes the elastic force of the elastic part and moves toward the direction close to the substrate; when the electromagnet is powered off, the electromagnet loses the magnetic field, so that the electromagnet loses the magnetic attraction to the matching piece, so that the moving body moves in the direction away from the substrate under the action of the elastic part; however, whether the moving body moves in the direction close to the substrate or moves away from the substrate, it can drive the nozzle to move along the extension direction of the cavity, thereby realizing the adjustment of the nozzle position. At the same time, the magnetic attraction that the electromagnet can apply to the matching piece can be adjusted by adjusting the current of the electromagnet, so as to realize the precise control and precise adjustment of the distance between the moving body and the substrate, thereby further improving the accuracy of the nozzle position adjustment, and further improving the polishing effect of the cavity.

[0018] Optionally, the moving body has a receiving cavity with its cavity opening facing the base body, the base body has a guide section extending into the receiving cavity, the guide section has a mounting cavity with its cavity opening facing the moving body, and at least part of the elastic part is located in the mounting cavity.

[0019] By adopting the above technical solution, when the moving body and the base body move relative to each other, the guide section and the cavity wall of the accommodating cavity slide relative to each other, so that the cooperation between the guide section and the accommodating cavity can guide the movement of the moving body, so as to limit the movement direction of the moving body and increase the movement stability of the moving body, while ensuring the adjustment efficiency and accuracy of the nozzle. Since at least part of the elastic part is located in the installation cavity, the stability of the elastic part is increased, and at the same time, the elastic part and the side wall of the accommodating cavity form a avoidance to avoid the elastic part contacting the side wall of the accommodating cavity and affecting the relative movement of the moving body and the base body, thereby ensuring the normal adjustment of the nozzle and increasing the working stability of the software-driven nozzle adjustment device.

[0020] Optionally, a blocking portion is provided at the cavity opening of the accommodating cavity, and a limiting portion is provided at the end of the guiding section, and the limiting portion can cooperate with the blocking portion to stop the moving body in the axial direction.

[0021] By adopting the above technical solution, after the electromagnet is powered off, the elastic part gradually recovers its deformation, and then the moving body moves in the direction away from the base under the action of the elastic part, and when the blocking part moves to the position of the limiting part, the blocking part cooperates with the limit part stopper, so that the moving body cannot continue to move in the direction away from the base, so as to limit the movement range of the moving body, avoid the guide section from escaping from the accommodating cavity and causing the elastic part to escaping from the installation cavity, thereby increasing the stability of the elastic part; in addition, it also avoids the situation that the guide section cannot move into the accommodating cavity when the electromagnet is powered on again.

[0022] Optionally, the electromagnet is arranged on a side of the limiting portion facing the cavity opening of the accommodating cavity, and the matching piece is arranged on a side of the moving body facing away from the accommodating cavity.

[0023] By adopting the above technical solution, since the electromagnet is arranged on the side of the limiting part facing the cavity opening of the accommodating cavity, the electromagnet is located in the accommodating cavity, so as to greatly reduce the risk of the electromagnet contacting the liquid, thereby greatly reducing the requirements for the waterproof performance of the electromagnet, so as to reduce the production cost of the software-driven nozzle adjustment device; at the same time, it also avoids the situation that the cavity wall of the required polishing cavity may be scratched by the electromagnet, so as to greatly reduce the risk of damage to the electromagnet, thereby reducing the failure rate of the software-driven nozzle adjustment device; in addition, when the electromagnet generates magnetic attraction to the matching piece, the limiting part can block and support the electromagnet, so as to greatly reduce the requirements for the fixing strength of the electromagnet, thereby reducing the production difficulty of the software-driven nozzle adjustment device. Since the matching piece is arranged on the side of the moving body away from the accommodating cavity, when the electromagnet applies magnetic attraction to the matching piece, the moving body can block and support the matching piece, which can also greatly reduce the requirements for the fixing strength of the matching piece, so as to further reduce the production difficulty of the software-driven nozzle adjustment device; at the same time, the matching piece can also block and protect the moving body to a certain extent, so as to reduce the risk of damage to the moving body, thereby ensuring the service life of the software-driven nozzle adjustment device.

[0024] Optionally, a plurality of the limiting portions are arranged at intervals along the circumference of the guide segment, a plurality of the blocking portions are arranged at intervals along the circumference of the accommodating cavity, and a passage for the limiting portion to pass through is formed between two adjacent blocking portions.

[0025] By adopting the above technical solution, when assembling the moving body and the base together, the limiting part is first aligned with the through-port, and then the moving body or the base is pressed so that the limiting part enters the accommodating cavity through the through-port, and then the moving body or the base is rotated, and then the limiting part is misaligned with the through-port and overlaps with the blocking part, thereby achieving the effect of facilitating the assembly of the moving body and the base, greatly reducing the difficulty of assembling the moving body and the base, and thus improving the production efficiency of the soft-driven nozzle adjustment device. And after the flexible adjustment wire is inserted into the moving body and the base, the flexible adjustment wire can limit the moving body and the base, so as to avoid the relative rotation of the moving body and the base causing the limiting part to be opposite to the through-port, thereby avoiding the risk that the moving body may be separated from the base during the use of the soft-driven nozzle adjustment device.

[0026] Optionally, the base and the moving body are both provided with a fixing frame for fixing the end of the elastic part.

[0027] By adopting the above technical solution, since both the base and the moving body are provided with fixing frames for fixing the ends of the elastic part, the two ends of the elastic part are fixedly connected to the base and the moving body respectively. On the one hand, the connection stability between the base and the moving body is increased, and on the other hand, the fixing frame can restrain the elastic part to increase the stability of the elastic part and ensure the elastic driving effect of the elastic part on the moving body.

[0028] Optionally, the driving member includes a first electromagnet and a second electromagnet arranged opposite to each other, wherein the first electromagnet and the second electromagnet are respectively arranged on the base and the moving body, and the first electromagnet and the second electromagnet have a first energized state in which they repel each other and a second energized state in which they attract each other.

[0029] By adopting the above technical solution, in the first power-on state, the first electromagnet and the second electromagnet generate a mutually repelling force, so that the moving body moves in a direction away from the substrate under the action of the first electromagnet and the second electromagnet; and in the second power-on state, the first electromagnet and the second electromagnet generate a mutually attractive force, so that the moving body moves in a direction close to the substrate under the action of the first electromagnet and the second electromagnet, so as to realize the movement of the moving body in a direction close to or away from the substrate. In addition, the current of the first electromagnet and the second electromagnet can be adjusted to realize the adjustment of the magnitude of the magnetic attraction or magnetic repulsion between the two, so as to realize the precise control of the moving distance of the moving body, and then realize the precise adjustment of the nozzle position.

[0030] Optionally, the moving body at the end is provided with a fixed pipe, the nozzle is threadedly connected to the outer end of the fixed pipe, and the abrasive hose is connected to the inner end of the fixed pipe.

[0031] By adopting the above technical solution, since the nozzle is threadedly connected to the outer end of the fixed tube, the difficulty of replacing the nozzle is reduced, so as to improve the replacement efficiency of the nozzle and increase the connection stability between the nozzle and the moving body.

[0032] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0033] 1. The software-driven nozzle adjustment device in the present application includes a driving section, a flexible connecting sleeve, a nozzle, an abrasive hose and a flexible adjustment wire. There are at least two driving sections, each of which includes a base, a moving body and a driving member for driving the moving body to move toward or away from the base. The flexible connecting sleeve is arranged between two adjacent driving sections, and the two ends of the flexible connecting sleeve are respectively fixedly connected to the base and the moving body. The nozzle is detachably connected to the moving body at the end to follow the movement of the moving body at the end. The abrasive hose is passed through the flexible connecting sleeve and the driving section and one end is connected to the nozzle. A plurality of flexible adjustment wires are arranged along the circumference of the driving section, each flexible adjustment wire is passed through a plurality of driving sections, and each flexible adjustment wire has a stop end that cooperates with a stopper of the moving body at the end. As a result, during the process of polishing the cavity, no staff operation is required, and the whole process is automatically operated, thereby improving the polishing efficiency of the cavity and reducing the workload of the staff. At the same time, the accuracy of adjusting the nozzle position is ensured, thereby improving the polishing quality of the cavity.

[0034] 2. The driving member in the present application includes an electromagnet provided on one of the base and the moving body, a matching piece provided on the other of the two and having ferromagnetism, and an elastic body provided between the base and the moving body. When the electromagnet is in an energized state, the electromagnet generates a magnetic attraction on the matching piece, so that the moving body overcomes the elasticity of the elastic part and moves toward the direction close to the base, thereby realizing the adjustment of the nozzle position. At the same time, the magnitude of the magnetic attraction that the electromagnet can apply to the matching piece can be adjusted by adjusting the current of the electromagnet, so as to realize the precise control and precise adjustment of the distance between the moving body and the base, thereby further improving the accuracy of the nozzle position adjustment, and further improving the polishing effect of the cavity.

[0052] Reference Figures 1 to 8 , discloses a soft-driven nozzle adjustment device for abrasive water jet polishing, which includes a driving section 1, a flexible connecting sleeve 2, a nozzle 3, an abrasive hose 4 and a flexible adjustment wire 5; wherein at least two driving sections 1 are provided, each driving section 1 includes a base 11, a moving body 12 and a driving member 13 for driving the moving body 12 to move toward or away from the base 11; the flexible connecting sleeve 2 is provided between two adjacent driving sections 1, and the two ends of the flexible connecting sleeve 2 are respectively fixedly connected to the base 11 and the moving body 12; the nozzle 3 is detachably connected to the moving body 12 located at the end to follow the movement of the moving body 12 located at the end; the abrasive hose 4 is passed through the flexible connecting sleeve 2 and the driving section 1 and one end is connected to the nozzle 3; a plurality of flexible adjustment wires 5 are provided along the circumference of the driving section 1, each flexible adjustment wire 5 is passed through a plurality of driving sections 1, and each flexible adjustment wire 5 has a stop end that cooperates with the stop of the moving body 12 located at the end.

[0053] It should be noted that the above-mentioned “the two ends of the flexible connection sleeve 2 are respectively fixedly connected to the base 11 and the moving body 12” means that a plurality of driving sections 1 are arranged in sequence, and then the moving body 12 of one of the two adjacent driving sections 1 is arranged opposite to the base 11 of the other driving section 1, and the two ends of the flexible connection sleeve 2 are respectively connected to the relative moving bodies 12 and the base 11 of the two adjacent driving sections 1, so that the movement strokes of the plurality of moving bodies 12 can be superimposed to increase the adjustable range of the nozzle 3. The “moving body 12 located at the end” mentioned in this application refers to the moving body 12 of the plurality of moving bodies 12 that does not have a driving section 1 in the direction away from the base 11, and the “base 11 located at the end” refers to the base 11 of the plurality of bases 11 that does not have a driving section 1 in the direction away from the moving body 12.

[0054] When the soft-driven nozzle adjustment device in the present application is used to polish the cavity, firstly, a suitable number of driving sections 1 are selected according to the length of the cavity, and then the soft-driven nozzle adjustment device is assembled according to the selected number of driving sections 1, so that the nozzle 3 is installed on the moving body 12 located at the end, one end of the abrasive hose 4 is connected to the nozzle 3, and then the end of the flexible adjustment wire 5 away from the stop end is connected to the winding device, the other end of the abrasive hose 4 is connected to the abrasive supply device, and the base 11 located at the end is connected to the abrasive supply device or the winding device, so that the abrasive supply device or the winding device supports the base 11 located at the end; then The soft-driven nozzle adjustment device is extended into the cavity to be polished; when the soft-driven nozzle adjustment device is extended into the cavity, the winding device winds up the flexible adjustment wire 5 on the corresponding side according to the shape of the cavity, and the two adjacent driving sections 1 move relative to each other under the action of the flexible adjustment wire 5, so that an angle matching the cavity is formed between the two adjacent driving sections 1, so that the nozzle 3 moves to the position where the cavity needs to be polished; when the nozzle 3 moves to the position where the cavity needs to be polished, the abrasive supply device transports the polishing liquid to the abrasive hose 4, so that the polishing liquid is ejected from the nozzle 3 after passing through the abrasive hose 4, so as to realize the polishing operation of the cavity.

[0055] When adjusting the polishing position, the driving member 13 is started, and the driving member 13 drives the moving body 12 to move the moving body 12 relative to the base 11, so that the moving body 12 drives the nozzle 3 to move to the next required polishing position. During this process, no staff operation is required, and the entire process is automatically operated, thereby improving the polishing efficiency of the cavity and reducing the workload of the staff. At the same time, the accuracy of the position adjustment of the nozzle 3 is ensured, thereby improving the polishing quality of the cavity.

[0056] When the flexible adjusting wire 5 is wound up, the flexible connecting sleeve 2 will undergo elastic deformation under the action of the driving section 1 and bend toward the side where the wound flexible adjusting wire 5 is located, so that when the wound flexible adjusting wire 5 is unwound, the two adjacent driving sections 1 can move toward a coaxial position under the action of the flexible connecting sleeve 2, so that when the flexible adjusting wire 5 on the other side is wound up, the flexible connecting sleeve 2 can also bend toward the other side under the action of the driving section 1, so that the two adjacent driving sections 1 form an angle on the other side, so that the soft-driven nozzle adjustment device can advance and perform polishing operations in a cavity with multiple bends, and at the same time, the nozzle 3 can be adjusted in the cavity with multiple bends, so as to greatly improve the polishing efficiency and polishing quality of the cavity, and also greatly reduce the difficulty of polishing the cavity with multiple bends.

[0057] In addition, since the nozzle 3 is detachably connected to the moving body 12 at the end, a suitable nozzle 3 can be selected according to the shape of the cavity to increase the flexibility of the software-driven nozzle adjustment device and increase the polishing quality of the cavity using the software-driven nozzle adjustment device.

[0058] The present application does not specifically limit the structure of the driving member 13, and the driving member 13 may adopt any one of the following embodiments:

[0059] Embodiment 1. In this embodiment, referring to Figure 3 and Figure 8 The driving member 13 includes an electromagnet 131 disposed on one of the base 11 and the moving body 12, a matching piece 132 disposed on the other of the base 11 and the moving body 12 and having ferromagnetism, and an elastic portion 133 disposed between the base 11 and the moving body 12. When the electromagnet 131 is in an energized state, the electromagnet 131 generates a magnetic attraction on the matching piece 132, so that the moving body 12 overcomes the elasticity of the elastic portion 133 and moves toward the direction close to the base 11.

[0060] Specifically, when the electromagnet 131 is powered on, the electromagnet 131 generates a magnetic field and generates a magnetic attraction to the matching piece 132, so that the moving body 12 overcomes the elastic force of the elastic part 133 and moves toward the direction close to the base 11. When the electromagnet 131 is powered off, the electromagnet 131 loses the magnetic field, thereby losing the magnetic attraction generated on the matching piece 132, so that the moving body 12 moves in the direction away from the base 11 under the action of the elastic part 133. However, whether the moving body 12 moves in the direction close to the base 11 or moves in the direction away from the base 11, it can drive the nozzle 3 to move along the extension direction of the cavity, thereby realizing the adjustment of the position of the nozzle 3. At the same time, the current of the electromagnet 131 can be adjusted, so that the magnitude of the magnetic attraction applied by the electromagnet 131 to the matching piece 132 can be adjusted, so as to realize the precise control and precise adjustment of the distance between the moving body 12 and the base 11, thereby further improving the accuracy of the position adjustment of the nozzle 3, and further improving the polishing effect of the cavity.

[0061] The present application does not specifically limit the material of the matching piece 132. Preferably, the matching piece 132 is made of an iron material to ensure that when the electromagnet 131 is energized, the matching piece 132 can be magnetically attracted by the electromagnet 131. In other embodiments, the matching piece 132 can also be made of a ferromagnetic material such as cobalt or nickel.

[0062] The present application does not specifically limit the structures of the moving body 12 and the base body 11, and they may adopt any one of the following embodiments:

[0063] Embodiment 1, in this embodiment, refer to Figure 3 , Figure 4 and Figure 6 The moving body 12 has a receiving cavity 121 with its opening facing the base body 11, the base body 11 has a guide section 111 extending into the receiving cavity 121, the guide section 111 has a mounting cavity 113 with its opening facing the moving body 12, and at least a portion of the elastic portion 133 is located in the mounting cavity 113.

[0064] It can be understood that the direction of the opening of the accommodating cavity 121 and the direction of the opening of the installation cavity 113 are opposite to each other.

[0065] Specifically, when the moving body 12 and the base 11 move relative to each other, the guide section 111 and the wall of the accommodating cavity 121 slide relative to each other, so that the cooperation between the guide section 111 and the accommodating cavity 121 can guide the movement of the moving body 12, so as to limit the movement direction of the moving body 12 and increase the movement stability of the moving body 12, while ensuring the adjustment efficiency and accuracy of the nozzle 3.

[0066] Since at least part of the elastic portion 133 is located in the installation cavity 113, the stability of the elastic portion 133 is increased, and at the same time, the elastic portion 133 forms a avoidance with the side wall of the accommodating cavity 121 to prevent the elastic portion 133 from contacting the side wall of the accommodating cavity 121 and affecting the relative movement of the moving body 12 and the base 11, thereby ensuring the normal adjustment of the nozzle 3 and increasing the working stability of the software-driven nozzle adjustment device.

[0067] Better, refer to Figure 6 The base 11 also includes an exposed section 112 located outside the accommodating cavity 121. When the elastic portion 133 is compressed to the limit position, the exposed section 112 abuts against the end of the moving body 12 close to the exposed section 112, so that the two stoppers cooperate to avoid the elastic portion 133 from deforming excessively and affecting the ability to deform again.

[0068] Further, see Figures 4 to 7 A blocking portion 122 is provided at the mouth of the accommodating cavity 121 , and a limiting portion 114 is provided at the end of the guiding section 111 . The limiting portion 114 can cooperate with the blocking portion 122 in the axial direction of the moving body 12 .

[0069] It can be understood that the blocking portion 122 is located inside the accommodating cavity 121 , and the limiting portion 114 is located outside the guiding section 111 .

[0070] Specifically, after the electromagnet 131 is powered off, the elastic portion 133 gradually recovers its deformation, and then the moving body 12 moves in the direction away from the base 11 under the action of the elastic portion 133. When the blocking portion 122 moves to the position of the limiting portion 114, the blocking portion 122 cooperates with the limiting portion 114 to prevent the moving body 12 from continuing to move in the direction away from the base 11, so as to limit the movement range of the moving body 12, avoid the guide section 111 from escaping from the accommodating cavity 121 and cause the elastic portion 133 to escaping from the installation cavity 113, thereby increasing the stability of the elastic portion 133; in addition, it also avoids the situation where the guide section 111 cannot move into the accommodating cavity 121 when the electromagnet 131 is powered on again.

[0071] The present application does not specifically limit the installation positions of the electromagnet 131 and the matching piece 132. Preferably, refer to Figure 3 , Figure 4 and Figure 6 The electromagnet 131 is arranged on the side of the limiting portion 114 facing the cavity opening of the accommodating cavity 121, that is, the electromagnet 131 is located in the accommodating cavity 121, so as to greatly reduce the risk of the electromagnet 131 contacting with the liquid, thereby greatly reducing the requirements for the waterproof performance of the electromagnet 131, so as to reduce the production cost of the software-driven nozzle adjustment device; at the same time, it also avoids the possibility that the cavity wall of the required polishing cavity may be scratched by the electromagnet 131, so as to greatly reduce the risk of damage to the electromagnet 131, thereby reducing the failure rate of the software-driven nozzle adjustment device; in addition, when the electromagnet 131 generates magnetic attraction to the matching piece 132, the limiting portion 114 can block and support the electromagnet 131, so as to greatly reduce the requirements for the fixing strength of the electromagnet 131, thereby reducing the production difficulty of the software-driven nozzle adjustment device. The matching piece 132 is arranged on the side of the moving body 12 away from the accommodating cavity 121, so that when the electromagnet 131 applies magnetic attraction to the matching piece 132, the moving body 12 can block and support the matching piece 132, which can also greatly reduce the requirements for the fixing strength of the matching piece 132, so as to further reduce the production difficulty of the software-driven nozzle adjustment device; at the same time, the matching piece 132 can also block and protect the moving body 12 to a certain extent, so as to reduce the risk of damage to the moving body 12, thereby ensuring the service life of the software-driven nozzle adjustment device.

[0072] In addition, since the electromagnet 131 is arranged on the side of the limiting portion 114 facing the cavity opening of the accommodating cavity 121, and the matching piece 132 is arranged on the side of the moving body 12 away from the accommodating cavity 121, the distance between the electromagnet 131 and the matching piece 132 can be greatly reduced to increase the magnetic attraction effect of the electromagnet 131 on the matching piece 132 when power is supplied.

[0073] In other implementation examples, the electromagnet 131 may also be disposed on the side of the base 11 away from the moving body 12 ; or, the electromagnet 131 is disposed on the side of the moving body 12 away from the base 11 , and the matching piece 132 is disposed on the side of the base 11 away from the moving body 12 .

[0074] The present application does not specifically limit the structures of the limiting portion 114 and the blocking portion 122. Preferably, refer to Figure 5 and Figure 7 A plurality of limiting portions 114 are arranged at intervals along the circumference of the guide section 111 , a plurality of blocking portions 122 are arranged at intervals along the circumference of the accommodating cavity 121 , and a through hole 123 for the limiting portion 114 to pass through is formed between two adjacent blocking portions 122 .

[0075] That is to say, both the limiting portion 114 and the blocking portion 122 are block structures, so as to reduce the production cost of the base body 11 and the moving body 12 .

[0076] Specifically, when assembling the moving body 12 and the base 11 together, first align the limiting portion 114 with the through port 123, and then press the moving body 12 or the base 11 to allow the limiting portion 114 to enter the accommodating cavity 121 through the through port 123, and then rotate the moving body 12 or the base 11, so that the limiting portion 114 is misaligned with the through port 123 and has an overlapping portion with the blocking portion 122, thereby achieving the effect of facilitating the assembly of the moving body 12 and the base 11, thereby greatly reducing the difficulty of assembling the moving body 12 and the base 11, and thereby improving the production efficiency of the software-driven nozzle adjustment device. After the flexible adjustment wire 5 is passed through the moving body 12 and the base 11, the flexible adjustment wire 5 can limit the moving body 12 and the base 11 to prevent the moving body 12 and the base 11 from rotating relative to each other, causing the limiting portion 114 to be opposite to the through port 123, thereby avoiding the risk of the moving body 12 being separated from the base 11 during the use of the software-driven nozzle adjustment device.

[0077] In other implementation examples, the limiting portion 114 may also be an annular structure surrounding the guide section 111 , and the blocking portion 122 may be a screw or rod-shaped structure penetrating the moving body 12 .

[0078] Further, see Figure 3 The base 11 and the moving body 12 are both provided with a fixing frame 124 for fixing the end of the elastic part 133, so that the two ends of the elastic part 133 are fixedly connected to the base 11 and the moving body 12 respectively. On the one hand, the connection stability between the base 11 and the moving body 12 is increased, and on the other hand, the fixing frame 124 can restrain the elastic part 133 to increase the stability of the elastic part 133 and ensure the elastic driving effect of the elastic part 133 on the moving body 12.

[0079] Embodiment 2, in this embodiment, refer to Figure 8 The base 11 and the moving body 12 are both hemispherical structures, and the base 11 and the moving body 12 are relatively provided with placement cavities, one end of the elastic part 133 is located in the placement cavity of the base 11, and the other end of the elastic part 133 is located in the placement cavity of the moving body 12, so as to reduce the friction between the driving section 1 and the required polishing cavity, and at the same time avoid the occurrence of the driving section 1 and the inner wall of the cavity stuck, so as to ensure the smoothness of the driving section 1 when entering or exiting the cavity.

[0080] Preferably, receiving grooves are arranged on the opposite end faces of the base 11 and the moving body 12, and the electromagnet 131 and the matching piece 132 are respectively located in the two receiving grooves to greatly reduce the distance between the electromagnet 131 and the matching piece 132, thereby increasing the magnetic attraction effect of the electromagnet 131 on the matching piece 132.

[0081] The present application does not specifically limit the structure of the elastic part 133. Preferably, the elastic part 133 is a spring to reduce the production cost of the soft drive nozzle adjustment device and ensure the elastic driving effect of the elastic part 133 on the moving body 12. In other embodiments, the elastic part 133 can also be an elastic sheet or an elastic column or other elastic structures.

[0082] Embodiment 2. In this embodiment, the driving member 13 includes a first electromagnet and a second electromagnet that are arranged opposite to each other. The first electromagnet and the second electromagnet are respectively arranged on the base 11 and the moving body 12. The first electromagnet and the second electromagnet have a first energized state that repels each other and a second energized state that attracts each other.

[0083] Specifically, in the first power-on state, the first electromagnet and the second electromagnet generate a mutually repelling force, so that the moving body 12 moves in a direction away from the base 11 under the action of the first electromagnet and the second electromagnet; and in the second power-on state, the first electromagnet and the second electromagnet generate a mutually attractive force, so that the moving body 12 moves in a direction close to the base 11 under the action of the first electromagnet and the second electromagnet, so as to realize the movement of the moving body 12 in a direction close to or away from the base 11. In addition, the magnitude of the magnetic attraction or magnetic repulsion between the first electromagnet and the second electromagnet can be adjusted by adjusting the current of the first electromagnet and the second electromagnet, so as to realize the precise control of the moving distance of the moving body 12, and then realize the precise adjustment of the position of the nozzle 3.

[0084] It should be noted that, in the first power-on state, both the first electromagnet and the second electromagnet generate magnetic fields, and the same magnetic poles of the first electromagnet and the second electromagnet are arranged relative to each other, so that the first electromagnet and the second electromagnet repel each other; in the second power-on state, both the first electromagnet and the second electromagnet generate magnetic fields, and the opposite magnetic poles of the first electromagnet and the second electromagnet are arranged relative to each other, so that the first electromagnet and the second electromagnet attract each other.

[0085] In a preferred embodiment, referring to Figure 2 The moving body 12 at the end is provided with a fixed tube 125, and the nozzle 3 is threadedly connected to the outer end of the fixed tube 125, thereby reducing the difficulty of replacing the nozzle 3 and improving the replacement efficiency of the nozzle 3. At the same time, the connection stability between the nozzle 3 and the moving body 12 is increased, and the abrasive hose 4 is connected to the inner end of the fixed tube 125.

[0086] Preferably, one end of the abrasive hose 4 is sleeved on the outside of the fixed tube 125 to connect the two, and a clamp 126 is provided on the outside of the abrasive hose 4, which can apply a force to the abrasive hose 4 against the fixed tube 125 to increase the stability of the two and facilitate the replacement of the abrasive hose 4.

[0087] The present application does not specifically limit the formation method of the stop end. Preferably, the stop end is formed by a block structure provided at the end of the flexible adjustment wire 5 to reduce the production difficulty of the flexible adjustment wire 5. In other embodiments, the stop end can also be formed by a rod-shaped structure provided at the end of the flexible adjustment wire 5.

[0088] The present application does not specifically limit the structure of the flexible adjustment wire 5. Preferably, the flexible adjustment wire 5 is a steel wire passing through the moving body 12 and the base 11 to ensure the adjustment effect on the driving section 1. In other embodiments, the flexible adjustment wire 5 can also be a structure made of other flexible materials.

[0089] The present application does not specifically limit the structure of the flexible connection sleeve 2. Preferably, the flexible connection sleeve 2 is a hose. In other embodiments, the flexible connection sleeve 2 may also be a corrugated tube.

[0090] It can be understood that the base 11 and the moving body 12 in the present application are both made of non-ferromagnetic materials, such as plastic, aluminum material, etc.

[0091] The present application also discloses a method for using a soft-driven nozzle adjustment device, which is used to use the above-mentioned soft-driven nozzle adjustment device, including the following steps: S1, determine the number of drive sections 1 and select a suitable nozzle 3, select a suitable number of drive sections 1 and select a suitable nozzle 3 according to the position required for polishing in the cavity. S2, assemble the soft-driven nozzle adjustment device, assemble the soft-driven nozzle adjustment device according to the selected number of drive sections 1, and install the selected nozzle 3 on the moving body 12 located at the end, that is, thread the nozzle 3 to the fixed pipe 125. S3, connect the abrasive supply device and the winding device, connect the end of the abrasive hose 4 away from the nozzle 3 to the abrasive supply device, and connect the flexible adjustment wire 5 to the winding device, so that the winding device can reel or unreel the flexible adjustment wire 5, and the abrasive supply device can transport the polishing liquid into the abrasive hose 4 and spray it out through the nozzle 3. S4, insert the soft drive nozzle adjustment device into the cavity, and during the insertion process, the flexible adjustment wire 5 is reeled by the reeling device, so that the angle between the two adjacent drive sections 1 matches the shape of the cavity, and finally the nozzle 3 moves to the desired polishing position, and then the abrasive device delivers the polishing liquid to the abrasive hose 4 and the polishing liquid is ejected to the desired polishing position through the nozzle 3. S5, adjustment of the nozzle 3, when adjusting the polishing position, start the driving member 13, so that the driving member 13 adjusts the distance between the base 11 and the moving body 12, so that the moving body 12 drives the nozzle 3 to move, so as to achieve the adjustment of the nozzle 3.

[0092] Since the above-mentioned method is used to polish the cavity using a software-driven nozzle adjustment device, the polishing steps of the cavity are simplified, the time required for polishing the cavity is shortened, thereby improving the polishing efficiency of the cavity, and at the same time, the position of the nozzle 3 can be accurately adjusted, thereby improving the polishing quality of the cavity.
