Description

Technical Field

[0001] This utility model relates to the field of guide assembly equipment, specifically a free turbine secondary guide assembly platform. Background Technology

[0002] To improve engine efficiency, turbines are generally composed of multi-stage blades. When the combustion gas impacts the first set of blades, it flows to the guide vane around the turbine, guiding it to the next stage of the turbine to continue working. This is the guide vane, which is generally a centrally symmetrical structure with a spiral channel. The shape of the channel is similar to that of the turbine blades, much like a centrifugal fan. In existing turbine engines, the turbine guide vane is one of the important stator and flow channel components, located at the very front of the turbine components. Its main function is to change the airflow direction, expand and accelerate the combustion gas, and convert the potential energy of the high-temperature combustion gas into kinetic energy. Existing turbine second-stage guide vanes are fixed by using fixing clamps during installation. However, since the fixing clamps are not convenient for adjusting and fixing guide vanes of different sizes, the applicability of the assembly platform is limited. Utility Model Content

[0003] The purpose of this utility model is to provide a free turbine second-stage guide assembly platform to solve the problem mentioned in the background art that the existing turbine second-stage guide is fixed by a fixing clamp during installation. However, the fixing clamp is not convenient for adjusting and fixing guides of different sizes, which limits the applicability of the assembly platform.

[0023] Please see Figure 1 , Figure 3 The fixing component 4 includes a rotating platform 41 rotatably installed inside the mounting sleeve 3. The top of the rotating platform 41 is provided with an arc-shaped groove 42, which extends arc-shapedly from the center of the rotating platform 41 to the edge. A connecting rod 43 is slidably inserted inside the arc-shaped groove 42. The top of the mounting sleeve 3 is provided with a stroke groove 44 corresponding to the arc-shaped groove 42. One end of the connecting rod 43 is inserted inside the stroke groove 44. Multiple fixing clamps 45 are arranged around the top of the mounting sleeve 3. The top of the connecting rod 43 is fixedly connected to the bottom of the fixing clamps 45. A driving device is provided inside the mounting sleeve 3, and the driving device is connected to the rotating platform 41 for transmission.

[0024] In practical use: A rotating platform 41 is rotatably installed inside the mounting sleeve 3. The top of the rotating platform 41 has multiple arc-shaped grooves 42, which extend from the center of the rotating platform 41 to the edge. When the drive device drives the rotating platform 41 to rotate, the connecting rod 43 slides inside the arc-shaped groove 42 under the limit of the stroke groove 44 at the top of the mounting sleeve 3. When the rotating platform 41 drives the connecting rod 43 to move towards the center inside the arc-shaped groove 42, the multiple connecting rods 43 drive the fixing clamps 45 to move closer to each other and fix the guide. When the guide size is different, the rotating platform 41 rotates in the opposite direction, driving the connecting rod 43 to move towards the edge inside the arc-shaped groove 42, causing the fixing clamps 45 to expand, making it easier to adjust and fix according to the guide size.

[0025] Please see Figure 1 , Figure 4 The pressing assembly 5 includes an arched frame 51 fixedly installed on the surface of the assembly table 1. An electric hydraulic cylinder 52 is fixedly installed on the top of the arched frame 51. A pressing block 53 is installed on the telescopic end of the electric hydraulic cylinder 52. The pressing block 53 is correspondingly set on the top of the mounting sleeve 3.

[0026] In practical use: An arched frame 51 is installed on the top of the assembly table 1. An electric hydraulic cylinder 52 is fixedly installed on the top of the arched frame 51. When the electric hydraulic cylinder 52 works, it pushes the pressing block 53 at the telescopic end to move towards the surface of the mounting sleeve 3, which facilitates the pressing of the guide fixed inside the fixed clamp 45.

[0027] Please see Figure 3 The drive device includes a servo motor 6 fixedly installed on the inner wall of the mounting sleeve 3. A drive gear 7 is fixedly installed on the output end of the servo motor 6. A gear ring 8 is fixedly installed on the bottom end of the rotating table 41.

[0036] In practical use: When the control panel 13 is connected to an external power source, the electric hydraulic cylinder 52 and the servo motor 6 are powered on and controlled to run; when the control panel 13 is disconnected from the external power source, the device stops running.

[0037] A rotating platform 41 is rotatably mounted inside the mounting sleeve 3. The top of the rotating platform 41 has multiple arc-shaped grooves 42, which extend from the center of the rotating platform 41 to the edge. When the drive device drives the rotating platform 41 to rotate, the connecting rod 43 slides inside the arc-shaped groove 42 under the limit of the stroke groove 44 at the top of the mounting sleeve 3. When the rotating platform 41 drives the connecting rod 43 to move towards the center inside the arc-shaped groove 42, the multiple connecting rods 43 drive the fixing clamps 45 to move closer to each other and fix the guide. When the guide size is different, the rotating platform 41 rotates in the opposite direction, driving the connecting rod 43 to move towards the edge inside the arc-shaped groove 42, causing the fixing clamps 45 to expand, which is convenient for adjustment and fixation according to the guide size.
