Aeroengines have a large number of blades, which are the core parts of the aeroengine, and the quality of the blades directly affects the performance and life of the engine. Blade polishing is an important procedure for improving the working life, fatigue strength and aerodynamic performance of the blade.

The blade of the aeroengine has a complex structure, and meanwhile, because the blade material is generally titanium alloy or high-temperature alloy, the hardness is higher, the loss to the mechanical polishing head is also larger, and the polishing cost is high, so the application of the automatic mechanical polishing in the blade polishing is also limited.

As a novel surface polishing technology, the laser polishing has the advantages of no contact and easiness in automation, and is very suitable for polishing irregular special-shaped curved surfaces of blades. However, laser is used as a thermal processing technology, a high-energy focusing laser beam is utilized to melt the surface of a material, the molten metal flows automatically to realize polishing, and a remelting layer remains on the surface after polishing. The crystal structure of the remelting layer is changed, and the remelting layer can become a weak area in a complex severe environment, so that the usability of the blade is affected, and the application of laser polishing on the aviation blade is greatly limited.

To solve the above-described problems, the present embodiment provides a laser polishing apparatus for laser polishing a blade 100 of an aero-engine. As shown in fig. 1-4, the laser polishing device comprises a machine table 1, wherein a bearing table 2 is rotatably arranged on the machine table 1, a plurality of clamping assemblies 7 are arranged on the bearing table 2 at intervals along the circumferential direction, and a preheating assembly 3, a laser polishing assembly 4, a heat preservation assembly 5 and a cooling assembly 6 are sequentially arranged on the machine table 1 around the bearing table 2 along the rotation direction of the bearing table 2.

The polishing process of the laser polishing device is to preheat the blade 100 before laser polishing, and to keep the temperature and cool the blade 100 after laser polishing, so that the laser polishing device has the advantages of high efficiency, high processing quality and good consistency of laser polishing, is non-contact polishing, does not have polishing dead angles, and does not change the size of a workpiece during polishing. Wherein, preheating can raise the temperature of the blade 100, thereby raising the activity between the molecules of the blade 100, thereby reducing the energy requirement during laser polishing, controlling the amount of remelted metal during laser polishing, and reducing the remelted layer 101 during laser polishing. The heat preservation can carry out solution treatment on the blade 100 after laser polishing, and absorb the remelting layer 101, so that laser polishing of the remelting-free layer 101 of the blade 100 is realized. As shown in fig. 3 and 4, the remelted layer 101 of the blade 100 treated by the laser polishing apparatus has disappeared.

The laser polishing device can reduce or eliminate the remelting layer 101 on the surface of the blade 100, has good polishing quality, high efficiency and good consistency, and improves the service performance of the blade 100.

Each clamping component 7 of the laser polishing device clamps a blade 100, and the blade 100 sequentially passes through the preheating component 3, the laser polishing component 4, the heat preservation component 5 and the cooling component 6 along with the rotation of the bearing table 2. It will be appreciated that the key step of the laser polishing apparatus is laser polishing, so in order to improve efficiency, the time of the blade 100 in the laser polishing assembly 4 is taken as a reference time, and the carrying table 2 rotates once every time a reference time passes, so that the blade 100 moves to the next processing step.

However, this has a problem that it is easy to cause insufficient preheating and heat-retaining time, so that the temperature of the blade 100 before laser polishing is insufficient, or the heat-retaining time after laser polishing is insufficient, resulting in that a large amount of remelted layer 101 still exists on the surface of the blade 100.

In order to solve this problem, the preheating module 3 is provided in plural at successive intervals, and the insulating module 5 is provided in plural at successive intervals. When the blade 100 rotates along with the bearing table 2, the blade passes through the preheating assemblies 3 or the heat preservation assemblies 5 in sequence, so that the preheating and heat preservation time is prolonged, the processing efficiency can be ensured, and the remelting layer 101 on the surface of the blade 100 can be reduced or eliminated, so that the service performance of the blade 100 is ensured.

The clamping jaw 73 can clamp the blade 100 to ensure the stability of the blade 100, and the rotating cylinder 72 can drive the clamping jaw 73 to rotate through the rotating shaft, so that the blade 100 can rotate 180 degrees. When the blade 100 performs laser polishing under the laser polishing component 4, after one side polishing is finished, the laser polishing of the other side can be performed by turning 180 degrees, and the laser polishing component 4 does not need to rotate to the lower side of the blade 100, so that the space is saved, and the mechanism is simplified.

Preferably, the clamping assembly 7 further comprises a telescopic cylinder 71, the telescopic cylinder 71 is fixedly arranged on the carrying platform 2, and the rotary cylinder 72 is arranged on a piston rod of the telescopic cylinder 71. Because preheating component 3, laser polishing component 4, heat preservation subassembly 5 and cooling component 6 all set up in the periphery of plummer 2, after plummer 2 rotates, the piston rod of telescopic cylinder 71 can drive blade 100 and get into corresponding process, and when the processing is accomplished, the piston rod is retracted and is made blade 100 break away from corresponding process, and plummer 2 continues to rotate afterwards. The telescopic cylinder 71 can prevent the blade 100 from colliding with the preheating assembly 3, the laser polishing assembly 4, the heat preservation assembly 5 and the cooling assembly 6.

Preferably, the carrying floor 2 is provided with a robot arm 8, the robot arm 8 being able to move the blade 100 to the clamping jaw 73 and to be clamped by the clamping jaw 73.

When the blade 100 enters the heat-insulating cover 51, the heating pipe 52 in the heat-insulating cover 51 starts to heat up to raise the temperature in the heat-insulating cover 51, thereby insulating the blade 100. In the heat preservation process, the crystal lattice of the remelting layer 101 on the surface of the blade 100 starts to be dissolved so as to be changed into the same crystal lattice structure as other parts of the blade 100, thereby improving the service performance of the blade 100.

When the heat preservation assembly 5 preserves heat of the blade 100, the inside of the heat preservation cover 51 is in a vacuum state. It will be appreciated that the holding process is long and the blade 100 is susceptible to oxidation, so that a vacuum condition is required to protect the blade 100 from oxidation of the surface of the blade 100 to affect the performance.

Specifically, the heating pipe 52 is disposed around, and the vane 100 is located at an intermediate position of the heating pipe 52 during the heat preservation process.

As shown in fig. 8, the laser polishing assembly 4 includes a laser emitter 41 and a positioning probe 42, the laser emitter 41 can emit laser to polish the blade 100, the positioning probe 42 is slidably disposed on the laser emitter 41 in the vertical direction, and the positioning probe 42 can abut against the blade 100 to position the laser emitter 41. The positioning probe 42 moves downwards, when the blade 100 rotates to the laser polishing assembly 4 and is abutted against the positioning probe 42, the bearing table 2 stops rotating, the position of the blade 100 is the polishing position, the laser transmitter 41 scans and polishes the blade 100 according to a preset processing track, after one side polishing is finished, the blade 100 rotates, and polishing of the other side of the blade 100 is finished. When the laser polishing is finished, the positioning probe 42 moves upwards to avoid the blade 100, so that the blade 100 can rotate to the next process along with the bearing table 2.

The laser transmitter 41 includes an optical fiber 411, a collimator 412, a cooling member 413, a beam expander 414, a lens 418, a three-dimensional galvanometer 415, and a field lens 416.
