Description

Technical Field

[0001] This utility model relates to the field of core material adhesive hole processing technology, and in particular to a device for processing adhesive holes in the core material of a wind turbine blade liner structure. Background Technology

[0002] As a crucial component of wind power generation, the performance of wind turbine blades directly impacts the overall efficiency and lifespan of the wind turbine. In the manufacturing of wind turbine blades, the core material of the inner lining structure is typically made of lightweight, high-strength composite materials, such as PET foam or balsa wood, to provide excellent mechanical properties and lightweight characteristics. Due to the widespread application of vacuum infusion technology in blade manufacturing, to ensure uniform flow and full impregnation of the resin in the core material, it is usually necessary to process adhesive pores on the surface of the core material. These pores not only facilitate the rapid diffusion of resin inside the blade but also enhance the bonding strength between the core material and the reinforcing material, thereby improving the overall structural performance.

[0003] An existing device for producing adhesive holes in the core material of a wind turbine blade liner (publication number: CN215825481U) has at least the following drawbacks: Although the device fixes the needle plate to the lifting plate by locking pins to achieve the drilling of the core material, it requires manual lifting of the needle plate and sliding it into the lifting plate for fixing when installing the needle plate. This operation is laborious and cumbersome. In addition, the needle plate of this device is only suitable for one-time drilling in regular areas and cannot meet the processing needs of irregular areas, resulting in low adhesive hole processing efficiency and limited applicability. Therefore, we propose this utility model. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a device for processing adhesive holes in the core material of the inner lining structure of wind turbine blades.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for processing adhesive holes in the core material of a wind turbine blade liner includes a processing table. A conveyor belt is provided on the top surface of the processing table. A drilling structure and a fixing structure are provided above the processing table. The drilling structure includes a mounting frame fixed to the top surface of the processing table. A cylinder is fixed to the top surface of the mounting frame. The telescopic end of the cylinder passes through the top surface of the mounting frame and is fixed to a mounting plate. A needle plate is provided on the bottom surface of the mounting plate. A fixing frame is fixed to the top surface of the processing table. A drilling machine is provided on one side of the fixing frame.

[0007] As a further embodiment of this utility model, a lead screw is rotatably installed inside the fixing frame, and a fixing plate is threadedly connected to the outer circular wall of the lead screw. An electric push rod is fixed on the top surface of the fixing plate, and the output end of the electric push rod passes through the top surface of the fixing plate and is fixed to the drilling machine. A first motor is fixed on one side of the fixing frame, and the output end of a second motor passes through one side of the fixing frame and is fixed to one end of the lead screw.

[0008] As a further embodiment of this utility model, the fixing structure includes two clamping plates respectively disposed on both sides of the mounting plate. A mounting hole is provided on one side of the mounting plate. A rack is fixed on the side of the two clamping plates that are close to each other. The rack is slidably disposed inside the mounting hole. A gear is rotatably disposed inside the mounting hole. The gear meshes with the two racks. The two sides of the needle plate are slidably disposed on the side of the two clamping plates that are close to each other. A second motor is fixed on the top surface of the mounting plate. The output end of the second motor passes through the top surface of the mounting plate and is fixed to the gear.

[0009] As a further embodiment of this utility model, a number of placement plates are fixed on the top surface of the conveyor belt, and a number of fixing holes are opened on the top surface of the placement plates. The fixing holes are evenly distributed along the length direction of the placement plates. Two pressure plates are provided on the top surface of the placement plates, and bolts are rotatably provided on the top surface of the two pressure plates. The bolts are threadedly connected to the fixing holes.

[0010] As a further embodiment of this utility model, a guide rod is fixed inside the fixing frame, and the guide rod is slidably inserted into one side of the fixing plate.

[0011] As a further embodiment of this utility model, two connecting holes are provided on both sides of the mounting plate, and two connecting rods are fixed on the side of the two clamping plates that are close to each other. The connecting rods are slidably inserted into the interior of the connecting holes.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This glue hole processing device, through the setting of the punching structure and the fixing structure, places the needle plate under the mounting plate. The cylinder drives the mounting plate to descend, and the needle plate is located between two clamping plates. The second motor drives the gear to rotate, so that the two clamping plates move closer to each other to clamp and fix the needle plate. The operator only needs to place the needle plate on the conveyor belt, and the mounting plate and clamping plates can automatically clamp and fix the needle plate 204. There is no need for the operator to lift and install the needle plate, which reduces the operating pressure on the user.

[0014] The conveyor belt transports the core material. When the core material moves to the area below the needle plate, the cylinder pushes the needle plate down and drills holes in the regular area of ​​the core material. When the core material needs to be drilled in an irregular and complex manner, the conveyor belt transports the core material to the area below the drilling machine. The first motor drives the lead screw to rotate, causing the drilling machine to adjust its position. The electric push rod pushes the drilling machine down to process the glue holes in the core material, thereby improving the efficiency and adaptability of the device for processing glue holes and meeting various drilling needs of the core material.

A conveyor belt 2 is provided on the top surface of the processing table 1. A drilling structure and a fixing structure are provided above the processing table 1. The drilling structure includes a mounting frame 201 fixed to the top surface of the processing table 1. A cylinder 202 is fixed on the top surface of the mounting frame 201. The telescopic end of the cylinder 202 passes through the top surface of the mounting frame 201 and is fixed to a mounting plate 203. A needle plate 204 is provided on the bottom surface of the mounting plate 203. A fixing frame 205 is fixed on the top surface of the processing table 1. A drilling machine 206 is provided on one side of the fixing frame 205. The needle plate 204 and the drilling machine 206 are both prior art.

[0024] In this embodiment, a lead screw 207 is rotatably mounted inside the fixing frame 205. A fixing plate 208 is threadedly connected to the outer circular wall of the lead screw 207. An electric actuator 209 is fixed to the top surface of the fixing plate 208. The output end of the electric actuator 209 passes through the top surface of the fixing plate 208 and is fixed to the drilling machine 206. A first motor is fixed to one side of the fixing frame 205. The output end of the second motor passes through one side of the fixing frame 205 and is fixed to one end of the lead screw 207.

[0025] In this embodiment, the fixing structure includes two clamping plates 3 respectively disposed on both sides of the mounting plate 203. A mounting hole 301 is provided on one side of the mounting plate 203. A rack 302 is fixed to the side of each clamping plate 3 that is close to each other. The rack 302 slides within the mounting hole 301. A gear 303 is rotatably disposed inside the mounting hole 301, meshing with the two racks 302. The two sides of the needle plate 204 slide with the sides of the two clamping plates 3 that are close to each other. A second motor is fixed to the top surface of the mounting plate 203. The output end of the second motor passes through the top surface of the mounting plate 203 and is fixed to the gear 303. Through the perforation and fixing structures, the operator places the needle plate 204 below the mounting plate 203, and the cylinder 202 drives the mounting plate 203. The needle plate 204 is lowered so that it is positioned between two clamping plates 3. The second motor drives the gear 303 to rotate, causing the two clamping plates 3 to move closer together and clamp the needle plate 204, thereby reducing manual intervention when fixing the needle plate 204. Then, the conveyor belt 2 transports the core material. When the core material moves below the needle plate 204, the cylinder 202 pushes the mounting plate 203 and the needle plate 204 to descend and drill holes in the regular areas of the core material. When the core material needs to be drilled irregularly and complexly, the conveyor belt 2 transports the core material to below the drilling machine 206. The first motor drives the lead screw 207 to rotate, causing the drilling machine 206 to adjust its position. The electric push rod 209 pushes the drilling machine 206 to descend and perform glue hole processing on the core material, thereby improving the glue hole processing efficiency and adaptability of the device and meeting various drilling needs of the core material.

[0026] In this embodiment, a number of placement plates 4 are fixed on the top surface of the conveyor belt 2. A number of fixing holes 401 are opened on the top surface of the placement plate 4. The fixing holes 401 are evenly distributed along the length direction of the placement plate 4. Two pressure plates 402 are provided on the top surface of the placement plate 4. Bolts are rotatably provided on the top surface of the two pressure plates 402. The bolts are threadedly connected to the fixing holes 401. When conveying the core material, the operator can place the core material on the placement plate 4 and then rotate the bolts to make the pressure plates 402 clamp and fix the core material.

[0027] In this embodiment, a guide rod 5 is fixed inside the fixing frame 205. The guide rod 5 is slidably inserted into one side of the fixing plate 208. When the lead screw 207 rotates to move the fixing plate 208 and the drilling machine 206, the guide rod 5 guides and limits the movement of the fixing plate 208, making its movement more stable.

[0028] In this embodiment, two connecting holes 6 are provided on both sides of the mounting plate 203. Two connecting rods 601 are fixed on the side of the two clamping plates 3 that are close to each other. The connecting rods 601 are slidably inserted into the connecting holes 6. When the clamping plate 3 moves to clamp the needle plate 204, the connecting rods 601 slide in the connecting holes 6 to prevent the clamping plate 3 from tilting when it moves.

[0029] Working Principle: In use, the operator places the needle plate 204 under the mounting plate 203. The cylinder 202 drives the mounting plate 203 to descend, positioning the needle plate 204 between the two clamping plates 3. The second motor drives the gear 303 to rotate, causing the two clamping plates 3 to move closer together and clamp the needle plate 204 in place. The operator only needs to place the needle plate 204 on the conveyor belt 2; the mounting plate 203 and clamping plates 3 automatically clamp and fix the needle plate 204, eliminating the need for manual lifting and installation, thus reducing the operator's workload. The conveyor belt 2 then transports the core material. When the core material moves to below the needle plate 204, the cylinder 202 pushes the mounting plate 203 and needle plate 204 downwards, punching holes in the regular areas of the core material. When the core material needs to be drilled with irregular and complex holes, the conveyor belt 2 transports the core material to the bottom of the drilling machine 206. The first motor drives the lead screw 207 to rotate, causing the drilling machine 206 to adjust its position. The electric push rod 209 pushes the drilling machine 206 down to process the core material for glue hole processing. When the core material is being transported, the operator can place the core material on the placement plate 4 and then rotate the bolts to clamp and fix the core material with the pressure plate 402. When the lead screw 207 rotates and moves the fixing plate 208 and the drilling machine 206, the guide rod 5 guides and limits the movement of the fixing plate 208 to make its movement more stable. When the clamping plate 3 moves to clamp the needle plate 204, the connecting rod 601 slides in the connecting hole 6. The clamping plate 3 is tilted when it moves.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
