Embodiment Construction
[0013] The present invention will be further described below in conjunction with the accompanying drawings.
[0014] as attached Figure 1-2 : A folding seven-axis welding robot structure, including a fixed base 1, a cantilever 2, a swivel base 3, a large arm 4, a small arm fixed base 5, a small arm extension 6, a small arm 7 and a wrist 8; The seat 1 is connected to one shaft end of the cantilever 2 through a one-axis reducer 11, and the one-axis reducer 11 drives the cantilever 2 to rotate horizontally through the first motor 12; the two-axis ends of the cantilever 2 are connected through a two-axis reducer 21 At the two-axis end of the turn base 3, the two-axis reducer 21 drives the turn base 3 to rotate horizontally through the second motor 22; the three-axis end of the turn base 3 is connected to the three-axis end of the boom 4 through the three-axis reducer 31 At the shaft end, the three-axis reducer 31 drives the boom 4 to rotate vertically through the third motor 32;...

The invention discloses a folding type seven-axis welding robot structure. The structure comprises a fixed seat, a cantilever, a rotating seat, a large arm, a small arm fixed seat, a small arm lengthening piece, a small arm and a wrist part, wherein the fixed seat is connected to the first-axis end of the cantilever through a first-axis speed reducer; the second-axis end of the cantilever is connected to the second-axis end of the rotating seat through a second-axis speed reducer; the third-axis end of the rotating seat is connected to the third-axis end of the large arm through a third-axis speed reducer; the fourth-axis end of the large arm is connected to the fourth-axis end of the small arm fixed seat through a fourth-axis speed reducer; the fifth-axis end of the small arm fixed seat is connected to one end of the small arm lengthening piece in a driving mode through a fifth motor, and the other end of the small arm lengthening piece is connected to the lengthening end of the small arm; the fifth-axis end of the small arm is in driving connection with the wrist part through a sixth motor; and the wrist part is in driving connection with the wrist part tail end flange through a seventh motor. Through the two continuous horizontal rotation structures, the working range of the tail end of the robot can be further enlarged, and the working blind area existing in the current robot working process is eliminated.
Description
technical field [0001] The invention relates to the technical field of robots, in particular to a structure of a folding seven-axis welding robot. Background technique [0002] At present, the traditional six-axis welding robot on the market will set the limit function on each joint, the purpose is to protect the internal cable and the body from being damaged by the wrong operation of the operator; especially the limit function set on the horizontal rotation axis of the first axis One axis can only rotate about ±170°, so that the end of the robot can only perform welding operations within the range of ±170°, and the back of the robot is about ±20°, which becomes a blind area of operation, resulting in a small operating range and many use restrictions And other issues. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a folding seven-axis welding robot structure that can eff...
