Embodiment Construction

[0016] Such as Figures 1 to 4 As shown, a specific embodiment of the present invention is given. In the figure, an eight-degree-of-freedom hybrid automatic welding robot is composed of two parts: a six-degree-of-freedom parallel robot 1 and a two-degree-of-freedom orientation adjustment mechanism 2, the above The two parts are connected in series through a mechanism static platform 200 .

[0017] Such as figure 2 , Figure 4 As shown, the above-mentioned six-degree-of-freedom parallel robot 1 includes a base 100, a moving platform 109, and mechanical legs 106 between the two. Respectively hinged with the first ball hinge 101 and the second ball hinge 108 on the base 100 and the moving platform 109; the mechanical leg 106 is driven by a ball screw nut mechanism; the mechanical leg 106 adopts a double-layer sleeve structure, wherein the outer sleeve 115 It runs through the entire mechanical leg, and its bottom is installed in the sleeve box 116. A drive motor 105 and a supp...

Abstract

The invention discloses an eight-degree-of-freedom series-parallel combined automatic welding robot, which consists of two parts of a six-degree-of-freedom parallel robot and a double-degree-of-freedom direction regulation mechanism which are connected in series through a movable platform to form the eight-degree-of-freedom series-parallel combined robot, wherein the six-degree-of-freedom parallel robot comprises a base, the movable platform and a mechanical leg which is arranged between the base and the movable platform, and the two ends of the mechanical leg are respectively hinged with the base and the movable platform; the double-degree-of-freedom direction regulation mechanism is installed on a mechanism static platform, the mechanism static platform is designed in consistence with the movable platform and is connected with the movable platform in series, the double-degree-of-freedom direction regulation mechanism is driven with a linear drive mode, a connection plate is arranged on the mechanism static platform, two direction drive motors are installed on a box body of the mechanism static platform on the connection plate, and are connected with a connection part of a welding output mechanism in a linear drive transmission way. The eight-degree-of-freedom series-parallel combined automatic welding robot has higher bearing capacity and control precision, the movement space of the parallel robot is prevented from being limited, and the welding performance with higher quality is further improved.

Description

technical field [0001] The invention relates to the field of robots, in particular to a hybrid automatic welding robot with eight degrees of freedom. Background technique [0002] Welding robots, as the name implies, refer to industrial robots engaged in welding operations including cutting and spraying. With the development of electronic technology, computer technology, numerical control and robot technology, since the automatic welding robot was used in production in the 1960s, its technology has become increasingly mature. Due to its good stability and high welding quality, it has greatly improved It improves labor productivity, improves the labor intensity of workers, and can work in a harmful environment, reduces the requirements for workers' operating skills, shortens the preparation cycle for product modification, reduces the corresponding equipment investment, etc., due to the above many Advantages, so it has been more and more widely used in all walks of life. At ...
