Problems solved by technology
However, when spraying curved surfaces, especially closed complex curved surfaces, the above two key factors are not easy to guarantee, so the quality of the coating after spraying cannot be guaranteed, and collision accidents between robot joints and components are prone to occur

Embodiment Construction
[0114] Such as Figure 1-3 As shown, a gas turbine component surface spray trajectory algorithm includes the following steps:
[0115] A, initial partition: such as image 3 Distance
[0116] (1), take any vertical vertical interception in an irregular surface, and take N points (P11-P1n) to the N-1 line segment on this intercept, take points to ensure the neighbor. The surface of the surface is close to the plane;
[0117] (2), the N points taken before the previous interception are the starting points to be divided into N-rooted interception, respectively, and each transverse interception is separately taken, and the starting point, closed curved surface. The starting point and the end point are the same point), split into M root line segment, and the lateral point is also guaranteed to ensure that the surface between the adjacent two points is close to the plane;
[0118] (3), to this, the surface is collected a total of N * M points (P11-PMN) to form an approximate planar region...

The invention discloses a trajectory algorithm for spraying a curved surface of a gas turbine component. The algorithm for spraying a trajectory of a curved surface comprises the following steps: the distance between the spray gun and the component of all trajectory points in the initial partition is in the optimal state; The spraying interval is divided into more spraying areas to form all the spraying trajectory points; the coordinates and attitude rotation information of these trajectory points are calculated by the spatial interpolation algorithm to ensure that the spatial coordinates of the trajectory points are correct, and finally the robot calculates the The information walks these track points in turn to complete the spraying; all the tracks between the sprayed layers are offset by 1 / 2 track spacing, so as to ensure that the peaks and troughs between the coating layers are better covered; the present invention adopts a A trajectory algorithm for spraying on curved surfaces of gas turbine components prevents collisions between robots and workpieces, improves spraying efficiency, does not cause damage to components, and improves spraying quality.
Description
Technical field [0001] The present invention belongs to the field of robot spraying, and more particularly to a gas turbine component surface spray trajectory algorithm. Background technique [0002] The components of the gas turbine work under very harsh conditions, they have long exposed to ultra-high temperature, creep, corrosion oxidation, high-week fatigue, etc. If there is no appropriate treatment, parts will be wear quickly, in some cases, they are Only a few seconds can last in use. Suitable coatings in the surface of the part can be used to significantly reduce wear, so that the components can use a longer period of time in a variety of harsh environments; spraying according to the position of the coating in the component into a diffusion coating and a surface coating. When the coating is diffused, the coating penetrates the interior of the component, and the surface coating is to spray the coating to the surface of the component to achieve protective, which is mainly us...
