Description

Technical Field

[0001] This utility model relates to the field of flange processing technology, and in particular to a tool clamping mechanism for boring holes in large-size wind turbine flanges. Background Technology

[0002] The machining industry has a demand for high-precision and high-stability processing of flanges. Its development history has been marked by technological innovation from traditional mechanical clamping to intelligent integration. With the development of industrial automation and precision manufacturing, various new clamping technologies such as hydraulic expansion and thermal shrinking have gradually become popular, significantly improving radial accuracy and vibration resistance. In recent years, intelligent clamping systems have become the forefront of technology. These technological breakthroughs not only meet the demand for high-precision processing of flange holes in industries such as automobiles and ships, but also achieve seamless collaboration with industrial robots through automated clamping units, promoting the transformation of the manufacturing industry towards digitalization and flexibility.

[0003] Flange boring is a process that uses a boring bar to precisely machine pre-drilled holes on a flange through the combined rotational and feed motions of the boring bar. Excess material is removed through the relative movement between the tool and the workpiece to achieve specified dimensional accuracy, shape accuracy, and surface quality. Different tools are required for boring flanges of different sizes and types. Existing equipment often uses a direct fixed connection for the tools, which makes disassembly and replacement cumbersome and complicated, increasing production time costs, reducing production efficiency, diminishing practicality, and narrowing the scope of application. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a tool clamping mechanism for boring holes in large-size wind turbine flanges, aiming to improve the problems of complicated tool replacement and inability to adjust the height in the prior art.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a tool clamping mechanism for boring holes in large-size wind turbine flanges, comprising a housing, a plurality of limiting grooves on the front side of the housing, a transmission frame rotatably connected to the inner wall of the plurality of limiting grooves, a first sliding groove on the inner wall of the transmission frame, a second sliding groove on the inner wall of the transmission frame, a second sliding column slidably connected to the inner wall of the first sliding groove, a slider fixedly connected to an adjacent end of the second sliding column, a guide rail slidably connected to the inner wall of the slider, a clamping arm fixedly connected to the front side of the slider, an air pump fixedly connected to the inner wall of the housing, a drive plate fixedly connected to the output end of the air pump, a plurality of first sliding columns fixedly connected to an adjacent side of the drive plate, and a height adjustment mechanism fixedly connected to the bottom of the housing for lifting and lowering the mechanism.

[0006] As a further description of the above technical solution: The height adjustment mechanism includes a mounting plate, the top of which is fixedly connected to the bottom of the outer casing. A fixing frame is fixedly connected to the bottom of the mounting plate. A rotating shaft is rotatably connected to the inner wall of the fixing frame. A roller is fixedly connected to the outer wall of the rotating shaft. Multiple solid columns are fixedly connected to the bottom of the outer casing. Springs are fixedly connected to the bottom ends of the multiple solid columns. Hollow tubes are slidably connected to the outer walls of the multiple solid columns. A base plate is fixedly connected to the bottom ends of the multiple hollow tubes. An air pump II is fixedly connected to the top of the base plate. An inclined block is fixedly connected to the output end of the air pump II. A slide rail is slidably connected to the bottom of the inclined block.

[0007] As a further description of the above technical solution: Multiple columns are fixedly connected to the front side of the outer shell, and pads are fixedly connected to the outer walls of the multiple columns.

[0008] As a further description of the above technical solution: A hinge is fixedly connected to the rear side of the outer casing, and a baffle is fixedly connected to the outer wall of the hinge.

[0009] As a further description of the above technical solution: The top of the base plate is fixedly connected to multiple limiting plates, and the bottom of the base plate is fixedly connected to multiple support columns.

[0010] As a further description of the above technical solution: The bottom of each of the support columns is fixedly connected to a base, and the bottom of the base is fixedly connected to an anti-slip pad.

[0011] As a further description of the above technical solution: The rear side of the guide rail is fixedly connected to the front side of the housing, and the outer wall of the first sliding column is slidably connected to the inner wall of the second sliding groove.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the air pump drives the drive plate to move back and forth. The drive plate transmits force to the transmission frame through the slide column, causing the transmission frame to rotate on the inner wall of the limiting groove. The slider also slides along the outer wall of the guide rail towards the center, and the clamping arm tightens towards the center to clamp and fix the tool. This makes it more convenient and faster to change different tools, avoids the complicated operation of flange boring, reduces production time costs, improves production efficiency, increases practicality, and expands the scope of application.

[0014] 2. In this utility model, the second air pump drives the inclined block to move back and forth along the slide rail. The inclined block and the roller cooperate with each other to convert the horizontal displacement of the inclined block into the vertical movement of the roller. The roller moves up and down, driving the fixed frame to move up and down together, thereby realizing the lifting and lowering of the mechanism. When boring flanges of different sizes and types, the height can be adjusted in time, which improves production efficiency, increases practicality, and expands the scope of application.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see the appendix Figure 3 Appendix Figure 4 and attached Figure 5 An embodiment of this utility model provides a tool clamping mechanism for boring holes in large-size wind turbine flanges, including a housing 1. Multiple limiting grooves 3 are provided on the front side of the housing 1. A transmission frame 7 is rotatably connected to the inner wall of the multiple limiting grooves 3. A sliding groove 8 and a sliding groove 9 are provided on the inner wall of the transmission frame 7. A sliding column 10 is slidably connected to the inner wall of the sliding groove 8. A slider 11 is fixedly connected to an adjacent end of the sliding column 10. A guide rail 12 is slidably connected to the inner wall of the slider 11. A clamping arm 13 is fixedly connected to the front side of the slider 11. An air pump 4 is fixedly connected to the inner wall of the housing 1. A drive plate 5 is fixedly connected to the output end of the air pump 4. Multiple sliding columns 6 are fixedly connected to an adjacent side of the drive plate 5. A height adjustment mechanism 2 is fixedly connected to the bottom of the housing 1. The height adjustment mechanism 2 is used for lifting and lowering the mechanism. Specifically, the outer shell 1 can maintain the stability and integrity of the structure and will not be deformed or damaged. The limiting groove 3 can effectively prevent the transmission frame 7 from deviating and over-rotating during the movement, ensuring the accuracy and reliability of the entire clamping mechanism. The clamping arm 13 can withstand the large clamping force and friction generated during the tool clamping process, ensuring that there will be no wear and deformation during long-term use, thus maintaining good clamping performance. The air pump 4 provides the initial power for the operation of the mechanism.

[0019] Please see the appendix Figure 2 Appendix Figure 6 and attached Figure 7 The height adjustment mechanism 2 includes a mounting plate 201, the top of which is fixedly connected to the bottom of the outer casing 1. A fixing frame 202 is fixedly connected to the bottom of the mounting plate 201. A rotating shaft 203 is rotatably connected to the inner wall of the fixing frame 202. A roller 204 is fixedly connected to the outer wall of the rotating shaft 203. Multiple solid columns 205 are fixedly connected to the bottom of the outer casing 1. Springs 206 are fixedly connected to the bottom ends of the multiple solid columns 205. Hollow tubes 207 are slidably connected to the outer walls of the multiple solid columns 205. A base plate 208 is fixedly connected to the bottom ends of the multiple hollow tubes 207. An air pump 209 is fixedly connected to the top of the base plate 208. An inclined block 210 is fixedly connected to the output end of the air pump 209. A slide rail 211 is slidably connected to the bottom of the inclined block 210. Specifically, the mounting plate 201 provides a mounting base for the components, ensuring that they will not loosen or fall off during operation. During height adjustment, the roller 204 reduces friction by rolling, allowing the inclined block 210 to smoothly push the roller 204 up and down, effectively reducing energy loss and improving the mechanism's efficiency. Air pumps 4 and 209 (model 4A12A30R48) provide the power source for the mechanism's operation. The slide rail 211 is fixedly connected to the top of the base plate 208, providing precise guidance for the movement of the inclined block 210. The slide rail 211 ensures that the inclined block 210 always moves along the predetermined direction during movement, without deviation or jamming, improving motion accuracy and reliability.

[0020] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 4 Multiple columns 20 are fixedly connected to the front side of the outer shell 1, and a pad 21 is fixedly connected to the outer wall of the multiple columns 20. A hinge 14 is fixedly connected to the rear side of the outer shell 1, and a baffle 15 is fixedly connected to the outer wall of the hinge 14. The rear side of the guide rail 12 is fixedly connected to the front side of the outer shell 1, and the outer wall of the sliding column 1 6 is slidably connected to the inner wall of the sliding groove 2 9. Specifically, the pad 21 can increase the friction between the components, thereby enhancing the stability of the connection; the baffle 15 can resist external collisions and impacts, preventing foreign objects from entering the mechanism during processing and damaging the cutting tools and other components; and the hinge 14 allows the baffle 15 to be opened flexibly, making it convenient for operators to operate.

[0021] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 Multiple limiting plates 16 are fixedly connected to the top of the base plate 208, multiple support columns 17 are fixedly connected to the bottom of the base plate 208, a base 18 is fixedly connected to the bottom of the multiple support columns 17, an anti-slip pad 19 is fixedly connected to the bottom of the base 18, the outer wall of the roller 204 is slidably connected to the top of the inclined block 210, and the bottom of the slide rail 211 is fixedly connected to the top of the base plate 208. Specifically, the limit plate 16 can maintain stable performance during long-term use and provide precise restriction for the operation of the mechanism; the support column 17 can better withstand forces from all directions; the base 18 can bear the weight of the equipment and distribute it evenly on the ground to avoid excessive local pressure that could damage the ground; and the anti-slip pad 19 can generate greater friction when in contact with the ground, effectively preventing the equipment from sliding due to external forces or its own vibration.

[0022] Working principle: When the air pump 4 is turned on, the back and forth movement of the air pump 4 will drive the drive plate 5 to move back and forth as well. The drive plate 5 will transmit the force to the transmission frame 7 through the slide column 6, causing the transmission frame 7 to rotate on the inner wall of the limit groove 3. While the transmission frame 7 is rotating, it will drive the slide column 10 to move towards the middle. The slider 11, which is fixedly connected to the slide column 10, will also slide towards the middle along the outer wall of the guide rail 12. The clamping arm 13, which is fixedly connected to the slider 11, will tighten towards the middle to clamp and fix the tool. When the air pump 209 is turned on, its forward and backward movement causes the inclined block 210 to move forward and backward along the slide rail 211. The special shape of the inclined block 210 can transmit power to the roller 204, so that the horizontal displacement of the inclined block 210 is converted into the vertical movement of the roller 204. The movement of the roller 204 causes the rotating shaft 203 and the fixed frame 202 to move up and down together. When the fixed frame 202 rises, it will stretch the spring 206 through the solid column 205. When the mechanism descends, the contraction of the slide column 6 can play an auxiliary role, realizing the height adjustment of the mechanism.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
