Description

Technical Field

[0001] This invention relates to the field of wing surface processing technology, and in particular to a method for fixing wing surfaces. Background Technology

[0002] In traditional manufacturing methods, the complex geometry of airfoils may be limited by mold making or processing techniques. However, 3D printing technology can precisely manufacture airfoils with complex internal structures and external shapes based on computer-aided design models.

[0003] The thin walls and variability of the airfoil make clamping a persistent challenge during manufacturing. Currently, jig-type tooling or pre-installed chucks are commonly used for clamping.

[0004] In the existing technology, the method of using a tire-type tooling has problems such as uneven contour leading to skin damage and poor stability. The method of using a pre-reserved chuck is prone to causing discontinuity in the machining process and difficulty in stably clamping the wing surface. Summary of the Invention

[0017] S6: Separate the wing surface from the wing surface fixing device.

[0018] Furthermore, the wing surface fixing device includes an auxiliary block, on which an adhesive surface is provided.

[0019] Furthermore, in step S1, according to the shape of the wing surface, multiple auxiliary blocks are arranged on the wing surface, and the auxiliary blocks are bonded to the wing surface through the adhesive surface.

[0020] Furthermore, a positioning part is provided on the other side of the auxiliary block that is bonded to the wing surface.

[0021] Furthermore, step S2 specifically includes the following steps:

[0022] S21: Align the auxiliary block;

[0023] S22: Machining positioning section.

[0024] Furthermore, the fixing column includes a connecting end for connecting the positioning part.

[0025] Furthermore, the positioning part is connected to the connecting end by bolts.

[0026] Furthermore, a sol-gel groove is provided on the bonding end face of the auxiliary block and the wing surface, and the sol-gel groove is used to extrude sol.

[0027] Furthermore, step S6 specifically includes:

[0028] S61: Extrusion of sol-gel agent;

[0029] S62: Separable airfoil;

[0030] S63: Recycle auxiliary blocks and fixing columns.

[0031] Furthermore, a connector is provided on the connecting end, and a positioning hole is machined on the positioning part, so that the connector can enter the positioning hole.

[0032] Furthermore, the connecting end is also provided with an air intake and a sealing strip. The air intake is connected to the negative pressure adsorption device, and the sealing strip is used to keep the positioning part and the connecting end sealed.

[0033] Furthermore, the fixing column also includes a clamping assembly, which is disposed inside the connecting end. The clamping assembly includes a connecting seat and a clamping block. The connecting head passes through the connecting seat, and the connecting seat cooperates with the positioning part, so that the positioning part is connected to the connecting seat through the connecting head.

[0034] Furthermore, the clamping assembly also includes a rotating handle, a rotating ratchet, and a rotating rod. The clamping block includes a chuck, a first spring, and a contact rod. The chuck is connected to the connecting end via the first spring. One end of the contact rod is connected to the chuck, and the other end contacts the rotating ratchet. The rotating ratchet is connected to the rotating rod, and the rotating handle is connected to the rotating rod.

[0035] Furthermore, the fixing column also includes a fixing test assembly, which is disposed inside the connection end and separated from the air intake. The fixing test assembly includes a detection block, a power supply component, an indicator light, a circuit housing, wires, and a contact switch. Multiple detection blocks are provided, which are disposed on the connection end and protrude from it. The connection end is connected to the circuit housing via a spring. The wires and contact switches are disposed inside the circuit housing. The power supply component forms a series circuit with the indicator light via the wires and contact switches.

[0036] Furthermore, a touch rod is provided on the detection block, and an entry hole is provided on the circuit housing. The touch rod enters the circuit housing through the entry hole. The position of the contact switch is matched with the touch rod. When the detection block is pressed and is on the same plane as the connection end, the touch rod is pressed and contacts the contact switch.

[0037] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0038] (1) The wing surface fixing method provided by the present invention involves arranging auxiliary blocks on the wing surface and bonding the auxiliary blocks to the wing surface. This allows the wing surface to be clamped by connecting the auxiliary blocks to a fixing column, enabling the wing surface to be processed on the processing platform of the machining machine. Bonding the auxiliary blocks to the wing surface replaces the traditional clamping of the wing surface. The bonding positions of the auxiliary blocks can be arranged according to the shape of the wing surface, allowing the wing surface fixing device to fix the wing surface according to its shape, increasing the stability and adaptability of the wing surface fixing device. Bonding instead of clamping prevents deformation or damage to the wing surface caused by clamping, improving the protection effect of the wing surface during processing. The addition of a solvent tank on the auxiliary blocks allows the solvent to better contact the bonding material, resulting in a better solvent effect. The wing surface fixing method of the present invention can improve the stability of wing surface fixing and effectively reduce the risk of wing surface being pinched or deformed by clamps during clamping.

[0039] (2) In the wing surface fixing method provided by the present invention, in step S3, the connection efficiency between the auxiliary block and the fixed post and the service life of the fixed post and the auxiliary block can be improved by connecting the auxiliary block with the clamping assembly. By moving the rotating handle, the clamping edge of the chuck can be fixed, thereby fixing the connection between the auxiliary block and the fixed post, avoiding damage to the auxiliary block and the fixed post caused by disassembling the bolts, and preventing phenomena such as stripping from affecting the stability of the connection between the fixed auxiliary block and the fixed post. By connecting the auxiliary block with the clamping assembly, the clamping degree between the chuck and the clamping block can be adjusted by simply adjusting the rotating handle, thereby facilitating the connection or separation of the fixing part and the connecting end. The operation is simple, and compared with the bolt connection, it can greatly save the time required to connect the fixing part and the connecting end, effectively saving manpower, improving operating efficiency, saving working time, and shortening the processing time of the wing surface, improving the continuity and smoothness of the processing.

[0040] (3) The wing fixing method provided by the present invention, in step S4, can improve the fixing effect of the wing by checking the stability of the connection between the fixing post and the auxiliary block, improve the safety and stability of the wing fixing device, and reduce the risk of unstable wing fixing. When the auxiliary block and the fixing post are connected by negative pressure adsorption, the stability of the connection between the auxiliary block and the fixing post can be automatically monitored by setting a fixing test component, and an alarm can be promptly issued to the staff. When the positioning part is connected to the connecting end, the positioning part squeezes the detection block, compresses the spring, and at the same time makes the touch rod contact the contact switch, so that the circuit is connected and the indicator light is lit; when the negative pressure suction force on the positioning part is insufficient, resulting in a gap in the connection between the positioning part and the connecting end, the detection block at the gap is pushed out from the connecting end by the spring reset action, drives the touch rod away from the contact switch, the circuit is broken, the indicator light goes out, and reminds the staff to check the stability of the connection between the positioning part and the connecting end, thereby realizing automatic monitoring of the stability of the connection between the auxiliary block and the fixing post and timely reminder of abnormal situations. It does not require manual inspection one by one, is easy to use, and can effectively increase the safety and stability of wing fixing.

[0041] (4) The wing surface fixing method provided by the present invention, in step S6, improves the utilization rate of the wing surface fixing device, saves costs and materials by recycling the auxiliary block and fixing post. After the wing surface is processed, solvent is squeezed into the solvent tank, allowing the solvent to penetrate into the bonding surface through the solvent tank, dissolving the adhesive material on the bonding surface, thereby separating the wing surface from the auxiliary block. After separating the auxiliary block from the fixing post, the auxiliary block and fixing post can be recycled and stored for reuse, increasing the number of recycling times and saving usage costs. When the positioning part separates from the connecting end, the detection block is driven by the spring reset action to move the touch rod away from the contact switch, making the circuit open and the indicator light off, thereby saving energy and improving the safety of the wing surface fixing device, and improving the economy and practicality of the wing surface fixing method.

[0042] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages may become apparent from the description or be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained through the embodiments described and the accompanying drawings, which are particularly pointed out.

Detailed Implementation

[0055] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of the present invention and are used together with the invention to illustrate the principles of the invention.

[0056] Example 1

[0057] This embodiment provides a wing surface fixing method, employing a wing surface fixing device, such as... Figure 1 As shown, it includes the following steps:

[0058] S1: Arrange auxiliary block 1 on wing surface 3;

[0059] S2: Align and process auxiliary block 1;

[0060] S3: Connect the auxiliary block to the fixed column;

[0061] S4: Check the stability of the connection between the fixed column 2 and the auxiliary block 1;

[0062] S5: Machining wing surface 3;

[0063] S6: Separate wing surface 3 from the wing surface fixing device.

[0064] like Figure 2 As shown, the wing surface fixing device includes an auxiliary block 1, and an adhesive surface is provided on the auxiliary block 1.

[0065] In step S1, specifically, according to the shape of the wing surface 3, multiple auxiliary blocks 1 are arranged on the wing surface 3, and the auxiliary blocks 1 are bonded to the wing surface 3 through the adhesive surface.

[0066] Furthermore, such as Figure 3 As shown, the wing surface fixing device also includes a fixing post 2. The auxiliary block 1 is provided with a positioning part 11 on the surface opposite to the bonding surface. The fixing post 2 includes a connecting end 21 and a support 22. The connecting end 21 is connected to the support 22 and is used to connect the positioning part 11.

[0067] Furthermore, step S2 specifically includes the following steps:

[0068] S21: Align auxiliary block 1;

[0069] S22: Machining positioning part 11.

[0070] In step S21, specifically, the other side of the auxiliary block 1 that is bonded to the wing surface 3 is aligned so that the other side of the auxiliary block 1 that is bonded to the wing surface 3 is coplanar.

[0071] In step S22, specifically, the positioning part 11 is processed so that the positioning part 11 can be connected to the connecting end 21.

[0072] For example, the positioning part 11 is connected to the connecting end 21 by bolts or screws, and a threaded hole is machined on the positioning part 11.

[0073] For example, such as Figure 4 As shown, the positioning part 11 and the connecting end 21 are connected by negative pressure adsorption. The connecting end 21 is provided with a connector 211, and the positioning part 11 is machined with a positioning hole so that the connector 211 enters the positioning hole, thereby positioning the positioning part 11 and increasing the stability of the connection.

[0074] In step S3, specifically, the fixed post 2 is connected to the auxiliary block 1, so that the wing surface 3 is fixed to the fixed post 2 by the auxiliary block 1.

[0075] For example, the positioning part 11 is connected to the connecting end 21 by bolts.

[0076] For example, such as Figure 4 As shown, the connecting end 21 is also provided with an air intake 212 and a sealing strip 213. The air intake 212 is connected to the negative pressure adsorption device, and the sealing strip 213 is used to keep the positioning part 11 and the connecting end 21 sealed. When the positioning part 11 is connected to the connecting end 21, it is sealed by the sealing strip 213, and the gas between the positioning part 11 and the connecting end 21 is drawn out through the air intake 212, so that the positioning part 11 and the connecting end 21 are connected by negative pressure adsorption.

[0077] For example, such as Figures 5-6 As shown, the fixing post 2 also includes a clamping assembly 23, which is disposed within the connecting end 21. The clamping assembly 23 includes a connecting seat 231 and a clamping block 232. The connecting head 211 passes through the connecting seat 231, and the connecting seat 231 cooperates with the positioning part 11, so that the positioning part 11 is positioned by the connecting head 211 and connected to the connecting seat 231. Figure 7 As shown, a clamping edge 111 is provided on the positioning part 11, and the clamping block 232 can fix the clamping edge 111, thereby fixing the connection between the positioning part 11 and the connecting seat 231.

[0078] Furthermore, the clamping assembly 23 also includes a rotating handle 233, a rotating ratchet 234, and a rotating rod 235. The clamping block 232 includes a chuck 2321, a first spring 2322, and a contact rod 2323. The chuck 2321 is connected to the connecting end 21 via the first spring 2322. One end of the contact rod 2323 is connected to the chuck 2321, and the other end contacts the rotating ratchet 234. The rotating ratchet 234 is connected to the rotating rod 235, and the rotating handle 233 is connected to the rotating rod 235. The rod 235 is connected, and the movable rotating handle 233 can drive the rotating rod 235 to rotate. The connecting end 21 is provided with a rotating handle groove 214. The rotating handle 233 extends out from the rotating handle groove 214 and can move along the rotating handle groove 214, thereby causing the rotating ratchet 234 to rotate. The rotating ratchet 234 pushes the contact rod 2323 to move, thereby driving the chuck 2321 to move closer to or away from the connecting seat 231, so that the chuck 2321 fixes the clamping edge 111.

[0079] In step S4, specifically, the stability of the connection between the fixed column 2 and the auxiliary block 1 is checked, and the unstable connection is reconnected.

[0080] For example, when the connecting end 21 is fixed to the positioning part 11 by bolts, the stability of the bolt connection is checked and the bolts are adjusted.

[0081] For example, when the connecting end 21 is connected to the positioning part 11 through the clamping assembly 23, the stability of the connection between the connecting end 21 and the positioning part 11 is checked, and the clamping head 2321 is adjusted to fix the clamping edge 111 by rotating the handle 233.

[0082] For example, such as Figures 8-9 As shown, the fixing column 2 also includes a fixing test component 24, which is disposed inside the connecting end 21 and used to test the stability of the connection between the connecting end 21 and the positioning part 11 through negative pressure adsorption. When negative pressure adsorption is used for fixing, the fixing test component 24 is separated from the air inlet 212 to avoid the fixing test component 24 being affected by the suction force of the negative pressure adsorption device, thus affecting the detection accuracy.

[0083] Furthermore, the fixed test assembly 24 includes a detection block 241, a power supply component 242, an indicator light 243, a circuit housing 244, a wire 245, and a contact switch 246. Multiple detection blocks 241 are configured, each located on and protruding from a connection end 21. The connection end 21 is connected to the circuit housing 244 via a spring. The wire 245 and the contact switch 246 are located within the circuit housing 244. The power supply component 242 forms a series circuit with the indicator light 243 via the wire 245 and the contact switch 246. For example, the power supply component 242 is a battery. When the contact switch 246 is not touched, the circuit is open, and the indicator light 243 does not illuminate. When the contact switch 246 is touched, the circuit is closed, and the indicator light 243 illuminates. A touch rod 2411 is provided on the detection block 241, and an entry hole 2441 is provided on the circuit housing 244. The touch rod 2411 enters the circuit housing 244 through the entry hole 2441. The position of the contact switch 246 is matched with the touch rod 2411. When the detection block 241 is pressed and is on the same plane as the connection end 21, the touch rod 2411 is pressed and contacts the contact switch 246, so that the circuit is turned on, thereby making the indicator light 243 light up.

[0084] Understandably, when the positioning part 11 is connected to the connecting end 21, the positioning part 11 presses the detection block 241, compressing the spring and simultaneously causing the touch rod 2411 to contact the contact switch 246, thus completing the circuit and causing the indicator light 243 to illuminate. When the negative pressure suction force on the tilted wing 3 is insufficient, resulting in a gap between the positioning part 11 and the connecting end 21, the detection block 241 at the gap protrudes from the connecting end 21 under the spring's reset action, causing the touch rod 2411 to leave the contact switch 246, breaking the circuit and extinguishing the indicator light 243, reminding the staff to check the stability of the connection between the positioning part 11 and the connecting end 21.

[0085] Preferably, the detection blocks 241 are evenly distributed at the corners of the connection end 21, thereby improving the accuracy of monitoring the negative pressure adsorption effect.

[0086] In step S5, specifically, after the wing surface 3 is connected to the fixed column 2 via the auxiliary block 1, the fixed column 2 is placed on the processing platform of the processing machine to process the wing surface 3.

[0087] Furthermore, such as Figure 3 As shown, a solvent groove 12 is provided on the end face of the auxiliary block 1 where it is bonded to the wing surface. The solvent groove 12 is used to inject solvent.

[0088] Furthermore, step S6 specifically includes:

[0089] S61: Extrusion of sol-gel agent;

[0090] S62: Separation wing surface 3;

[0091] S63: Recycle auxiliary block 1 and fixed column 2.

[0092] In step S61, specifically, after the processing of the wing surface 3 is completed, a solvent is squeezed into the solvent tank 12, so that the solvent penetrates into the bonding surface through the solvent tank 12 and dissolves the adhesive material on the bonding surface.

[0093] In step S62, specifically, after the adhesive material on the surface of the auxiliary block 1 dissolves, the wing surface 3 is lifted by the hoisting device to separate the wing surface 3 from the auxiliary block 1, and the wing surface 3 is transferred to the next process by the hoisting device.

[0094] In step S63, specifically, the connecting end 21 is separated from the positioning part 11, and the auxiliary block 1 and the fixing post 2 are retrieved for reuse.

[0095] For example, when the connecting end 21 is connected to the positioning part 11 by bolts, the bolts are removed to separate the connecting end 21 from the positioning part 11.

[0096] For example, when the connecting end 21 is connected to the positioning part 11 through the clamping assembly 23, the chuck 2321 is adjusted by rotating the handle 233 so that the chuck 2321 leaves the clamping edge 111, and the positioning part 11 is removed from the connecting seat 231, thereby separating the connecting end 21 from the positioning part 11.

[0097] For example, when the connecting end 21 and the positioning part 11 are connected by negative pressure adsorption, the negative pressure adsorption device is turned off, the positioning part 11 is separated from the connecting end 21, the detection block 241 is driven by the spring reset to move the touch rod 2411 away from the contact switch 246, so that the circuit is open and the signal light 243 is turned off, thereby saving power and improving the safety of the wing surface fixing device.

[0098] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
