Problems solved by technology
Traditional commercial robots are generally six-axis robots or six-axis robots + 1-2 axis turntables, but due to the limitations of the degrees of freedom (especially the degrees of freedom of the outer axes) of traditional commercial robots, they cannot meet the coating preparation requirements of gas turbine burners

Embodiment Construction
[0017] A nine-axis system for gas turbine burner spraying, including a three-axis turntable, a six-axis manipulator and a control cabinet.
[0018] Among them, the three-axis turntable has three degrees of freedom (that is, three rotation modes), and the first degree of freedom (rotation mode one) is realized by the first axis, which can make the workpiece rotate around the vertical axis in the horizontal direction. Degree of freedom 2 (rotation mode 2) is realized by the second axis, so that the workpiece can swing along the vertical plane around the horizontal axis. Degree of freedom 3 (rotation mode 3) is realized by the third axis, which can make the workpiece rotate around its own central axis.
[0019] Among them, the third axis (the innermost axis) reserves a cylinder as the workpiece clamping space, and there is a device for fixing the workpiece to be sprayed inside the cylinder.
[0020] Among them, the three degrees of freedom of the three-axis turntable are realize...

The invention discloses a nine-axis system for gas turbine burner spraying, which includes a three-axis turntable, a six-axis robot and a control cabinet; wherein: the three-axis turntable includes a base and a first axis joint arranged at the center of the base. A bracket is set at the end interface of the first shaft joint, a second shaft joint is set at both ends of the top of the bracket, a roller mechanism is connected to the motor end of the second shaft joint, a third shaft joint is arranged at both ends of the roller mechanism, and the inner diameter surface of the roller mechanism There are tooling fixing mechanisms evenly distributed on the top. Compared with the prior art, the positive effect of the present invention is: the present invention is a nine-axis linkage robot system that can meet the requirements for the preparation of the internal surface coating of the gas turbine burner, and can not only realize the 6-axis manipulator clamping the spray gun and the three-axis turntable clamping Coordinated movement of the holding workpiece, so as to realize the coating preparation of complex workpieces (such as gas turbine burners), and also realize convenient and fast clamping of gas turbine burners, and realize multiple displacement modes of clamped workpieces (such as burners) .
Description
technical field [0001] The invention relates to a nine-axis system for spraying a gas turbine burner. Background technique [0002] The gas turbine combustor is a device in which fuel or propellant is burned to generate high-temperature gas. The combustor must withstand harsh working conditions such as high temperature, high load, vibration load and thermal corrosion. Thermal barrier coating (TBC) can not only reduce the metal matrix The working temperature can also prevent high-temperature oxidation and thermal corrosion of high-temperature components, improve the efficiency of gas turbines, reduce fuel consumption, and prolong the service life of high-temperature components. Therefore, TBC has been widely used in high temperature components such as gas turbine combustors. In order to meet the functions of stable combustion and high-temperature gas acceleration, the burner is generally designed with a special shape. At the same time, the working surface of the burner is t...
