Description
Technical Field
[0001] The utility model belongs to the technical field of turbine blade laser processing, and more specifically, particularly relates to a turbine blade printing laser positioning component. Background Art
[0002] Turbine blades are an important component of the turbine section of a gas turbine engine. The high-speed rotating blades are responsible for drawing high-temperature and high-pressure airflow into the burner to maintain the operation of the engine. In order to ensure stable and long-term operation under extreme conditions of high temperature and high pressure, turbine blades are often forged with high-temperature alloys and cooled in different ways, such as internal airflow cooling, boundary layer cooling, or thermal barrier coatings to protect blades, to ensure reliability during operation. In steam turbine engines and gas turbine engines, metal fatigue of blades is the main cause of engine failure. Strong vibration or resonance may cause metal fatigue. Engineers often use friction dampers to reduce the damage to blades caused by these factors.
[0003] After searching, it was found that the application number is: CN201721872615.9, a safe, efficient and easy-to-cool 3D printer, and its content is: The utility model discloses a safe, efficient and easy-to-cool 3D printer, including a printer body, a raw material tank, a feed pipe, a pad, an LED lamp, a finished product outlet frame, a heat dissipation fan, a warmer, a USB interface, a heat dissipation strip, a pen bag and a hook. The top of the printer body is connected to the raw material tank through a feed pipe, and a feed inlet is provided at the top of the raw material tank. The output shaft of the stirring motor is connected to the rotating shaft, and multiple groups of stirring blades are installed on the rotating shaft. A pad is provided on one side of the top of the printer body, and a finished product outlet frame is provided at the bottom of the printer body. A heat dissipation fan and a warmer are provided on the inner wall of the finished product outlet frame, an LED lamp is provided on the front of the printer body, and a pen bag is also provided on the front of the printer body. Hooks are provided on both sides of the printer body, and heat dissipation strips are provided under the hooks.
[0004] The utility model listed avoids the precipitation of raw materials affecting the effect of subsequent 3D printing. According to the actual situation, the printed finished product is cooled or kept warm by the cooling fan and the insulator, so as to improve the effect of subsequent processing of 3D printing;
[0005] 1) Most traditional printing equipment is more suitable for printing 3D models, but it is not suitable for laser positioning in some high-precision printing solutions for turbine fans. Previously, although the laser printing link used probe scanning to scan, this scanning was only two-dimensional. Once the printing state of the turbine fan blades in three-dimensional space is taken into consideration, it is necessary to raise and lower the infrared laser that plays a positioning function to perform depth scanning. This requires the laser probe to be able to successfully achieve the same scanning detection solution in a two-dimensional plane in a three-dimensional space;
[0006] 2) Conventional scanning and laser detection methods require flexibility in laser scanning detection of finished turbine fan products, which requires ensuring that one of the laser positioning components can try to move layer by layer along the turbine blade printing stage to ensure that the two-dimensional laser positioning point can play a positioning effect in the three-dimensional space in depth;
[0007] 3) It is difficult to locate the printing coordinates of traditional turbine blades when equipped with a printer. Traditional coordinate positioning relies on sensors such as ultrasound or simulated infrared rays. Such waves are easily disturbed, resulting in inaccurate positioning during printing. In addition, during the laser positioning process of the turbine blades, it is easy to cause the laser positioning and the printing components to be incompatible.
[0008] Therefore, in view of this, the existing structure and defects are studied and improved, and a turbine blade printing laser positioning component is provided, in order to achieve a more practical purpose. Utility Model Content

[0015] The scanning assembly is arranged in the middle of the back of the outer frame bracket, and includes an electric telescopic cylinder arranged in the middle of the outer frame bracket;

[0018] As a preferred solution of the utility model: the laser positioning assembly includes a crossbeam arranged in the middle of the top end of the trapezoidal bracket, and pneumatic cylinders are respectively supported on both sides of the bottom of the crossbeam, and a steering motor is provided at the telescopic end of the pneumatic cylinder, and a pneumatic cylinder is installed at the output end of the steering motor, and one end of the pneumatic cylinder is provided with a scanning positioning base through a linkage with a motor.
[0019] As a preferred solution of the utility model: a laser transceiver for capturing positioning points is installed at one end of the scanning positioning base, a transceiver unit is installed on the surface of the laser transceiver, and the laser transceiver and the corresponding laser positioning tube form infrared coordinate positioning.
[0020] As a preferred solution of the utility model: a printer group is installed laterally in the middle of the linear sliding support plate;
[0021] The printer assembly comprises a connecting protrusion arranged transversely on the surface of a linear sliding support plate, a linear sliding rod is installed transversely on the surface of the connecting protrusion, and a lead screw motor for position translation change is arranged on the side walls of the rod bodies of the two linear sliding rods.
[0022] As a preferred solution of the utility model: a print shaping head is installed in the middle of the linear slide rod, a sensing probe for capturing positioning coordinates is installed on the surface of the print shaping head, and the bottom of the sensing probe is connected to a coordinate sensing device integrated in a square support plate.
[0023] As a preferred solution of the utility model: a fine-tuning motor for linear pushing is installed on the back of the square support plate, a driving screw is provided at the output end of the fine-tuning motor, and sliding struts are provided on both sides of the bottom of the driving screw, and the square support plate is set to slide linearly along the sliding struts by being constrained by the driving screw.
[0024] Compared with the prior art, the utility model has the following beneficial effects:
[0025] Beneficial effects of the utility model:
[0026] 1) The support state of the outer frame bracket and the trapezoidal bracket is ensured to realize the front and rear extension of the pneumatic cylinders on both sides after being restricted by the crossbeam connection. The front and rear extension of the pneumatic cylinders is used to coordinate the flipping of the steering motor, and the flipping of the scanning and positioning base is controlled by the flipping of the scanning and positioning base.

After the expansion of the scanning side plate, the specific position is extended based on the electric telescopic cylinder to ensure that the positioning grid presented by the laser scanning positioning plate position is mapped on the square pallet position;
[0028] 3) In order to solve the problem of determining the positioning point in three-dimensional space proposed by the background technology, the electric telescopic cylinder in the scanning component controls the telescopic connecting rod to lift upward. During the lifting process, the position of the scanning side plate will be lifted together. This scanning side plate is a two-dimensional plane solution, and the lifting effect is also to create a plane three-dimensional process. Because the working principle of the 3D printer is basically a stack of pieces superimposed to form a three-dimensional model, therefore, using this feature, when making a turbine fan, it is necessary to regulate the combination of the scanning side plate and the laser scanning positioning plate, and then lift the telescopic connecting rod up and down to change the height of the two-dimensional positioning point, so that each layer of superimposed blades can complete the specific level of scanning detection and positioning effect.
