Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, and in particular to an automated production polishing device for TRT blades. Background Technology

[0002] The surface roughness of the blades directly affects the frictional losses during airflow. Rough surfaces are prone to causing boundary layer separation, resulting in pressure fluctuations on the blade surface and increasing the risk of surge. Smooth surfaces, on the other hand, are less likely to adsorb particulate matter (such as rust and coal ash) from the gas, thus reducing efficiency degradation caused by fouling. Therefore, polishing is particularly important in the production process of TRT blades.

[0003] When polishing TRT blades, due to their numerous curvatures and curved surfaces, sandblasting is typically used to ensure uniformity and integrity of the polishing process. However, current sandblasting operations largely rely on manual handling of the workpiece and continuous angle adjustments to maintain processing quality. This method is not only labor-intensive and inefficient, but also makes it difficult to guarantee consistency and stability in the processing.

[0004] To address the aforementioned issues, it is necessary to develop an automated TRT blade production and polishing device to automate the sandblasting process, improve processing efficiency and quality consistency, reduce manual labor intensity, and enhance the overall level of production automation. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides an automated production and polishing device for TRT blades.

[0006] The technical implementation scheme of this utility model is as follows: an automated production and polishing device for TRT blades, comprising a mounting platform, a processing frame, a sandblasting device, a sand outlet pipe, a first motor, a rotating disk, a cover plate, a second motor, a rotating shaft, and mounting blocks. The mounting platform has symmetrically arranged and interconnected processing frames. A sandblasting device is installed in one of the processing frames for sandblasting and polishing the TRT blades. Both processing frames have sand outlet pipes connected to their rear sides for discharging excess polishing sand. A first motor with its output end facing upwards is also installed in the middle of the mounting platform. A rotating disk is connected to the output end of the first motor. Second motors are installed circumferentially on the rotating disk at intervals, with their output ends facing outwards. A cover plate is detachably installed on the rotating disk to cover the second motors. A rotating shaft, rotatably connected to the rotating disk, is connected to the output end of each first motor. The end of the rotating shaft is located outside the rotating disk. Mounting blocks for placing the TRT blades to be polished are provided on each rotating shaft.

[0007] Furthermore, it also includes a fastening frame, a hinge seat, and a baffle. The mounting block is slidably provided with a fastening frame, and hinge seats are provided on both sides of the fastening frame. A baffle is connected to each hinge seat.

[0008] Furthermore, it also includes elastic elements, with elastic elements provided between the two sides of the fastening frame and the inner wall of the corresponding mounting block.

[0009] Furthermore, it also includes a blower, which is installed on another processing frame to blow away excess polishing sand.

[0010] Furthermore, it also includes a rubber plate, with openings on the opposite sides of the two processing frames, and a rubber plate on each opening.

[0011] Furthermore, the rubber sheet is made of a telescopic rubber material.

[0012] The present invention has the following advantages: 1. The present invention sets up a first motor to drive a rotating disk, which drives multiple mounting blocks equipped with TRT blades mounted on it to move circumferentially. Combined with a second motor to precisely control the rotation of a single blade, and with the sandblasting device to carry out fixed-point sandblasting treatment, this not only achieves efficient and comprehensive polishing of TRT blades, but also avoids human error that is difficult to avoid in traditional manual operation, significantly improves the consistency and stability of product surface treatment, and simultaneously supports continuous operation mode, greatly improving the overall production efficiency.

[0013] 2. This utility model adopts a replaceable mounting block and snap-fit ​​frame structure, which can be quickly adjusted and adapted according to the specific size of the TRT blade to be processed, greatly improving the versatility and applicability of the equipment. This allows the equipment to quickly switch between different models or specifications of products without a complicated adjustment process, saving time, facilitating maintenance, and enhancing the flexibility and response speed of the production line.

[0014] 3. This utility model is specially equipped with a fan that can automatically blow and clean the surface of the TRT blades after the polishing process, effectively removing residual polishing abrasive particles. This function not only ensures the cleanliness of the blade surface and reduces quality problems caused by residues, but also simplifies the production process, reduces labor costs, and improves overall production efficiency and product quality.

Detailed Implementation

[0021] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] Example: An automated polishing device for TRT blade production, such as... Figures 1-5As shown, the device includes a mounting platform 1, a processing frame 2, a sandblasting device 3, a sand discharge pipe 4, a first motor 5, a rotating disk 6, a cover plate 7, a second motor 8, a rotating shaft 9, and a mounting block 10. The mounting platform 1 has symmetrically arranged and interconnected processing frames 2. A sandblasting device 3 is installed in one of the processing frames 2 for sandblasting and polishing the TRT blades 11. Both processing frames 2 have sand discharge pipes 4 connected to their rear sides for discharging excess polishing sand, facilitating the centralized collection or recycling of waste sand, maintaining the cleanliness of the equipment interior, and reducing environmental pollution. A first motor 5 with its output end facing upwards is also installed in the middle of the mounting platform 1. A rotating disk 6 is connected to the output end of the first motor 5. Both motors serve as the power core of the entire device, driving the rotating disk 6 and its components to rotate synchronously, enabling the automatic turnover and transportation of the TRT blades 11 between different workstations, effectively improving the overall automation level. Second motors 8 are installed at intervals along the circumference of the disk 6. The output ends of the second motors 8 are all facing outwards. To protect the second motors 8 from dust, a cover plate 7 is detachably installed on the rotating disk 6 to cover the second motors 8, which facilitates the subsequent daily maintenance and cleaning of the second motors 8. The output ends of the first motors 5 are all connected to rotating shafts 9 that are rotatably connected to the rotating disk 6. The ends of the rotating shafts 9 are located on the outside of the rotating disk 6. Each rotating shaft 9 is provided with a mounting block 10 for placing the TRT blades 11 to be polished. The mounting block 10 can be customized and has a groove for placing the root part of the TRT blade 11. Furthermore, the second motors 8 drive each mounting block 10 and the TRT blade 11 on it to rotate independently, so that the blade surface of the second motor 8 can receive all-round coverage polishing during the sandblasting process, improving the processing uniformity and quality consistency.

[0023] In summary, the automated production and polishing device for TRT blades 11 has a reasonable structure and complete functions, realizing fully automated operation from loading, positioning, polishing, cleaning to unloading, which significantly improves production efficiency and product consistency, and is suitable for the high-precision and high-efficiency polishing needs of TRT blades 11 in modern industry.

[0024] like Figure 1 , Figure 4 and Figure 5 As shown, it also includes a snap-fit ​​frame 12, a hinge seat 14, and a baffle 15. The snap-fit ​​frame 12 is slidably provided on the mounting block 10. The snap-fit ​​seat 14 is provided on both sides of the snap-fit ​​frame 12, and the baffle 15 is connected to the hinge seat 14. This structure allows the TRT blade 11 to be loaded or unloaded by simply pushing the snap-fit ​​frame 12 to adjust its position in the groove of the mounting block 10, thereby conveniently achieving stable clamping or release of the root part of the TRT blade 11.

[0025] like Figure 4 and Figure 5As shown, it also includes an elastic element 13. The elastic element 13 is provided between the two sides of the fastening frame 12 and the inner wall of the corresponding mounting block 10. In this embodiment, the elastic element 13 is a spring, which is used to provide the necessary restoring force so that the fastening frame 12 and its related components can automatically reset after the clamping action is completed, and maintain the tight fixation of the TRT blade 11.

[0026] like Figure 2 As shown, it also includes a blower 16. A blower 16 for blowing away excess polishing sand is installed on another processing frame 2. The blower 16 can effectively remove the polishing sand remaining on the surface of the TRT blade 11, so as to avoid affecting subsequent processes or causing environmental pollution.

[0027] like Figure 2 As shown, it also includes a rubber plate 17. Openings are provided on the opposite sides of the two processing frames 2. The rubber plate 17 is provided on each opening. The rubber plate 17 is made of rubber material with a telescopic structure. The rubber plate 17 allows the TRT blade 11 to pass smoothly into or out of the processing frame 2, while preventing external impurities from entering the processing area.

[0028] During use, firstly, select a suitable mounting block 10 according to the size of the TRT blade 11 to be polished, and install each mounting block 10 onto the corresponding rotating shaft 9. Then, push the fastening frame 12 on the mounting block 10 to slide it toward the rotating disk 6, and drive the baffle 15 to move synchronously, causing the elastic element 13 to deform accordingly. When the fastening frame 12 abuts against the wall of the rotating disk 6, the baffle 15 is squeezed and unfolded, and the hinge seat 14 rotates accordingly, causing the baffle 15 to expand and disengage from the groove position of the mounting block 10. At this time, the blade root of the TRT blade 11 can be placed into the groove of the mounting block 10. After releasing the fastening frame 12, under the reset action of the elastic element 13, the fastening frame 12 and its connecting parts return to their original positions, and the fastening frame 12 is re-embedded above the groove of the mounting block 10. At the same time, the baffles 15 on both sides return to a flat state and fit against the sides of the mounting block 10, thereby achieving a stable clamping of the blade root of the TRT blade 11. After all TRT blades 11 are loaded, the sandblasting device 3 is connected to the sand supply equipment, and the first motor 5 is started to drive the rotating disk 6 and its connected components to rotate, causing the loaded TRT blades 11 to sequentially enter the processing frame 2 circumferentially. During this process, when the TRT blades 11 pass through the opening, they will contact the rubber plate 17 and undergo elastic deformation, thus smoothly entering the processing frame 2 and accurately positioning themselves below the sandblasting device 3. At this time, the first motor 5 is paused, and the sandblasting device 3 and the second motor 8 are started. The sandblasting device 3 begins to perform targeted sandblasting and polishing on the TRT blades 11, while the second motor 8 drives the rotating shaft 9 to rotate, causing the mounting block 10 and the TRT blades 11 on it to rotate synchronously, achieving all-round, automated polishing operations. After polishing is completed, the first motor 5 is started again, allowing the TRT blades 11 to continue to be transported to the next processing frame 2, and the blower 16 is turned on simultaneously to blow away and clean the polishing sand remaining on the blade surface. At the same time, the waste sand in the two processing frames 2 is discharged uniformly through the sand outlet pipe 4 to ensure a clean working environment. The final processed TRT blade 11 is output from the other side port. During this process, the operator can disassemble the TRT blade 11 while it is being transferred. The operation method is the same as the aforementioned pushing process of the fastening frame 12, causing the fastening frame 12 to slide away from the groove of the mounting block 10, thereby releasing the clamping limit on the blade root and achieving rapid and complete removal of the blade. By continuously repeating the above process, continuous and automated polishing of the TRT blade 11 can be achieved between multiple production stations.

Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
