Description

Technical Field

[0001] This utility model relates to the field of precision gas turbines, and in particular to a laser device for marking precision gas turbine blades. Background Technology

[0002] As a highly efficient power equipment, precision gas turbines play a key role in many fields such as energy and aerospace. Their working principle is to convert the energy of fuel into mechanical energy by driving the impeller to rotate at high speed through continuous flow of gas. Among them, the blades, as one of the core components, determine the performance of the gas turbine.

[0003] To ensure the traceability of blades and meet the quality control requirements of the production process, markings are required during blade production. These markings contain key data such as the blade's number, batch, and material information. Currently, laser marking technology is commonly used to mark precision gas turbine blades. However, due to the curved structure of precision gas turbine blades, when they are placed on a workbench for laser marking, it is difficult for the laser beam to remain perpendicular to the blade surface. This results in uneven distribution of laser energy on the blade surface, which can easily lead to marking position deviation, affecting the accuracy and clarity of the markings.

[0004] To address this issue, we propose a precision laser marking device for gas turbine blades. Utility Model Content

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.

[0025] Please see Figure 1-5 This utility model discloses a precision laser marking device for gas turbine blades, comprising a support platform 1. A lifting device 3 is fixedly installed on one side of the support platform 1. The lifting device 3 adopts an electric screw lifting mechanism, the main body of which consists of a motor, a screw, a nut seat, and a guide mechanism. When the motor is energized and rotates, it drives the screw to rotate, and the nut seat moves up and down linearly on the screw, thereby driving the support plate 4 and the laser marking machine 5 to rise and fall. The telescopic end of the lifting device 3 is fixedly installed with the support plate 4, and the laser marking machine 5 is fixedly installed on one side of the support plate 4. The laser marking machine 5 mainly includes a laser generating system, an optical focusing system, and a scanning galvanometer system. The laser generating system includes a laser generator, which can select fiber lasers, lasers, etc., according to different marking requirements to generate laser beams of specific wavelengths and powers. An adjustment component 2 is fixedly installed on the bottom surface of the support platform 1, and an adjustment hole 12 is opened on the upper surface of the support platform 1. A support slide 6 is slidably connected to the inner wall of the adjustment hole 12. An electric push rod 7 is fixedly installed on the inner bottom wall of the support slide 6. A lifting slide plate 9 is fixedly installed at the telescopic end of the electric push rod 7. A fixed plate 8 is fixedly connected to the upper surface of the lifting slide plate 9. A movable clamping plate 10 is fixedly installed on the bottom surface of the fixed plate 8. A fixed clamping seat 11 is fixedly installed on one side of the support slide 6. The support plate 4 and the laser marking machine 5 are raised and lowered by the telescopic end of the lifting device 3. The vertical position of the laser marking machine 5 can be flexibly adjusted according to the different heights of the blades and the marking requirements to ensure that the laser beam can be aligned with the blade surface. The cooperation between the adjustment hole 12 and the support slide 6 can provide a track for the blade position adjustment. In addition, the blade clamping mechanism composed of the electric push rod 7, the lifting slide plate 9, the fixed plate 8 and the movable clamping plate 10 can cooperate with the fixed clamping seat 11 to clamp the blade and prevent the blade from sliding during the marking process, thus ensuring the marking accuracy.

[0026] In a further embodiment, the adjustment component 2 includes a variable frequency motor 201. A transmission screw 204 is fixedly installed at the output end of the variable frequency motor 201. A transmission slide plate 203 is fixedly installed on one side of the support slide 6. Two fixed seats 206 are fixedly connected to the outer surface of the variable frequency motor 201. The upper surfaces of the two fixed seats 206 are fixedly connected to the bottom surface of the support platform 1. A bearing seat 202 is fixedly connected to the bottom surface of the support platform 1. The outer surface of the transmission screw 204 is rotatably connected to the inner ring of the bearing seat 202. A threaded hole 205 is provided on one side of the transmission slide plate 203. The outer surface of the transmission screw 204 is threadedly connected to the inner wall of the threaded hole 205. By driving the rotation of the transmission screw 204 through the variable frequency motor 201, the transmission screw 204 can be threadedly driven with the threaded hole 205, which will drive the support slide 6 to slide along the adjustment hole 12. The bearing seat 202 can support the transmission screw 204, making the transmission screw 204 more stable when it operates.

[0027] In a further embodiment, two limiting sliders 17 are fixedly connected to the outer surface of the support slide 6. The outer surfaces of the two limiting sliders 17 are slidably connected to the inner wall of the adjustment hole 12. The sliding of the limiting sliders 17 on the surface of the support slide 6 inside the adjustment hole 12 plays a guiding and limiting role, ensuring the stability of the blade horizontal adjustment process. A support plate 13 is fixedly connected to the upper surface of the support platform 1. A control host 14 is fixedly installed on the front of the support plate 13. Rubber anti-slip pads 16 are provided on the side of the fixed clamp 11 and the movable clamp 10 that are close to each other. Multiple anti-slip textures are opened on the outer surface of the two rubber anti-slip pads 16. Two sets of The support base 15 supports the control host 14 on the surface of the support plate 13. The control host 14 integrates a central processing unit, a data storage module, an input / output interface module, and a control circuit. The central processing unit is the core of the control host 14, responsible for processing various control commands and data, and coordinating the operation of various components. The data storage module is used to store relevant programs, parameters, and marking data of the blade marking. It can accurately control the working parameters of the laser marking machine 5, and coordinate the operation of the lifting device 3, the electric push rod 7, and the frequency conversion motor 201 to ensure that the laser beam is as perpendicular as possible to the curved surface of the blade, ensuring uniform distribution of laser energy, and completing high-precision transfer marking of key data of the blade.

[0028] The working principle of this utility model is as follows: First, the device is connected to the power supply. Then, the gas turbine blade is placed above the fixed clamp 11. Next, the electric push rod 7 pushes the lifting slide plate 9 and the fixed plate 8 to drive the moving clamp 10 to move downward, which can cooperate with the fixed clamp 11 to clamp the blade. Then, the variable frequency motor 201 in the adjustment component 2 is started. The transmission screw 204 is threadedly engaged with the threaded hole 205 at the transmission slide plate 203, which can drive the support slide 6 to slide along the adjustment hole 12, and can adjust the marked position of the blade.

[0029] When the height of the laser marking machine 5 needs to be adjusted, the lifting device 3 is operated. Its telescopic end drives the support plate 4 and the laser marking machine 5 to rise and fall, so that the laser beam can be aligned with the appropriate position of the blade. Then, the laser marking machine 5 is controlled by the control host 14 to ensure that the laser energy is evenly distributed on the blade surface, thereby accurately completing the transfer marking of key data such as blade number, batch, and material information.
