Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, specifically to an aircraft engine blade clamping device. Background Technology

[0002] An aircraft engine is a machine that can convert other forms of energy into mechanical energy. It is applicable to power generation devices, and can also refer to the entire machine including the power device. Its types include internal combustion engines, external combustion engines, electric motors, etc. Engine blades are important components for the efficient operation of engines, so the requirements for engine blades in the industrial field are becoming increasingly higher.

[0003] According to the patent titled "An Aircraft Engine Blade Clamping Device" (patent publication number: CN216178569U, patent publication date: 2022-04-05), the device uses a clamp to hold blades. When clamping blades with different slopes at both ends, the elasticity of the elastic cotton and the pressure of the pressure plate work together to allow the clamp to hold blades with different slopes. Furthermore, the device can be adapted to clamp blades of different sizes by adjusting the position of the fixing plate, making it highly practical. The device uses a vacuum suction cup to adsorb and fix the blade. After fixing, because the blade has a certain slope and curved surface, the four sets of electric rods installed on the outer circumference of the connecting column, in conjunction with the lifting and adjusting mechanism, will make the center of the blade parallel to the support plate, facilitating better clamping and fixing of the blade by the subsequent clamp.

[0004] Based on the aforementioned existing technology, the existing aircraft engine blade clamping devices still have the following problems: when clamping blades, the position of the blades is usually fixed after clamping. However, when processing different surfaces of the blades, the existing devices need to repeatedly clamp the blades. Therefore, this utility model provides an aircraft engine blade clamping device.

[0026] Please see Figures 1-6 This utility model provides a technical solution:

[0027] An aircraft engine blade clamping device includes a base 1, and a clamping mechanism 2 is provided on the top of the base 1 for rotating the clamped blade to process different surfaces. The clamping mechanism 2 includes:

[0028] The lifting unit 21 is located on the top of the base 1 and is used to adjust the processing height of the blades to accommodate people of different heights.

[0029] The clamping unit 22 is located on the front side of the lifting unit 21 and is used to clamp the blade.

[0030] The rotating unit 23 is located above the clamping unit 22 and includes two sets of sliding sleeves 234 and rotating column 236. A first pulley 235 is fixedly installed on the outside of the sliding sleeve 234, and a second pulley 237 is fixedly installed on one end of the rotating column 236.

[0031] In this embodiment, the sliding sleeve 234 has a linkage groove 239 inside, and a rotating rod 233 is slidably installed inside the linkage groove 239. The rotating unit 23 also includes a bearing seat 231 and a rotating column 236.

The sliding sleeves 234 drive the first pulley 235 to rotate. The first pulley 235 drives the rotating column 236 to rotate via the belt 238. The rotating column 236 drives the clamping frame 229 to rotate, thereby realizing the rotation of the blade. This facilitates the processing of different surfaces of the blade without the need for repeated manual clamping of the blade.

[0033] In this embodiment, the lifting unit 21 includes a lifting box 211 fixedly installed on the top of the base 1. A lead screw 212 is rotatably installed inside the lifting box 211. A first motor 213 is fixedly installed on the top of the lifting box 211, and the top end of the lead screw 212 passes through the lifting box 211 and is fixedly connected to the first motor 213. A lifting block 214 is threaded on the outside of the lead screw 212, and the lifting block 214 slides inside the lifting box 211. A fixing plate 215 is fixedly installed on the front side of the lifting block 214.

[0034] The first motor 213 is a three-phase asynchronous motor with a self-locking function. It is electrically connected to an external power supply and can be opened and closed through a human-operated control panel. The operation of the first motor 213 drives the lead screw 212 to rotate, the lead screw 212 drives the lifting block 214 to move up and down, the lifting block 214 moves up and down, and the fixed plate 215 moves synchronously. The fixed plate 215 drives the clamping unit 22 and the rotating unit 23 to move synchronously, thereby realizing the up and down movement of the blades, which makes it convenient for people of different heights to use.

[0035] In this embodiment, the clamping unit 22 includes a clamping seat 221 fixedly mounted on the top of the fixing plate 215.

The sliding column 226 slides within the arc groove 223. A second motor 227 is fixedly mounted at the bottom of the fixing plate 215, and the output end of the second motor 227... The fixed plate 215, clamping seat 221 and turntable 222 are fixedly connected, and bearing seat 231 is fixedly installed at the left end of clamping seat 221.

[0036] The second motor 227 is a three-phase asynchronous motor with a self-locking function. It is electrically connected to an external power supply and its opening and closing operations are achieved through a human-operated control panel. The blade is placed between two clamping frames 229. The operation of the second motor 227 drives the turntable 222 to rotate. The rotation of the turntable 222 causes the rotating column 236 to slide inside the arc groove 223, thereby enabling the two sliding columns 226 to move towards each other, driving the two moving blocks 225 to move synchronously, and driving the clamping rod 228 to move synchronously with the clamping frame 229 to clamp the blade. While the clamping rod 228 moves, the sliding sleeve 234 slides synchronously on the surface of the rotating rod 233. The two threaded torsion bars 2210 are rotated to clamp the upper and lower positions of the blade to match the curvature of the blade.

[0037] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0038] During operation, the blade is first placed between two clamping frames 229. The second motor 227 drives the turntable 222 to rotate. The rotation of the turntable 222 causes the rotating column 236 to slide inside the arc groove 223, thereby realizing that the two sliding columns 226 move towards each other, driving the two moving blocks 225 to move synchronously, and driving the clamping rod 228 to move synchronously with the clamping frame 229 to clamp the blade. While the clamping rod 228 moves, the sliding sleeve 234 slides synchronously on the surface of the rotating rod 233.

[0039] Next, the two threaded torsion bars 2210 are rotated to clamp the blade to the upper and lower positions to match the curvature of the blade. Then, the first motor 213 runs and drives the lead screw 212 to rotate. The lead screw 212 drives the lifting block 214 to move up and down. The up and down movement of the lifting block 214 drives the fixed plate 215 to move synchronously. The fixed plate 215 drives the clamping unit 22 and the rotating unit 23 to move synchronously, thereby realizing the up and down movement of the blade and adjusting the position of the blade to a suitable position for the user to process.

[0040] Then, when processing different surfaces of the blade, the second pulley 237 drives the rotating rod 233 to rotate via the belt 238. The rotating rod 233 drives the two sliding sleeves 234 to rotate synchronously. The sliding sleeves 234 drive the first pulley 235 to rotate. The first pulley 235 drives the rotating column 236 to rotate via the belt 238. The rotating column 236 drives the clamping frame 229 to rotate, thereby rotating the blade and processing different surfaces of the blade.
