Embodiment Construction

[0050] Hereinafter, the arrangement structure of the cable etc. of the robot arm of this invention and the industrial robot equipped with it are demonstrated in detail based on drawing which shows embodiment. Figure 4 and Figure 5 The articulated arc welding robot 1 using the present invention is shown. (a) of Fig. 4 is the front view of the robot, (b) is its II-II line view, Figure 5 (a) is the III-III line view in Fig. 4(a), and (b) is the top view of the robot. Apart from Figure 5 Except (a), the upper arm 2 using the present invention is shown in any of the figures, and its shape and its mounting form are described. image 3 It is a plan view and a front view drawn so that the arrangement structure of the cable etc. of the upper arm 2 can be seen.

[0051] This arc welding robot 1 has six joints that perform actions indicated by arrows in FIG. The sixth axis 3 among the six axes of the arc welding robot rotates a welding torch 4 attached to a wrist as an end effect...

Abstract

A rotary arm 2 along which cables 8 and 43 are made to run, has a support member 35 in a rotary shaft body 7 positioned in its base end part. An inserting hole 36 for passing the cables is formed in its support member 35. Its whole opening surface is imparted to a position offset from the rotational axis 2a of the rotary arm 2. A rocking shaft is operated in a tip part of the rotary arm 2, and even if the cable 8 is bent large, the influence of its bending on the upstream side of the cable is minimized. To improve feeding stability and durability of a welding wire by minimizing an influence on an upstream side torch cable, by maintenance of a bending state in a joint and repetition of bending operation.

Description

technical field [0001] The present invention relates to an arrangement structure of cables and the like of a robot arm and an industrial robot equipped with the same. Specifically, it relates to, for example, a multi-joint type arc welding robot that, even if the torch cable is shortened, the position of the welding torch In any case, the supply speed and the stability of the supply amount of the welding wire can also be improved to achieve the required welding quality, and it is possible to realize the suppression of the loss of the welding torch cable and the arrangement structure of the cable and the like to expand the operating area of ​​​​the robot and possess It's industrial robots. Background technique [0002] An arc welding robot that feeds a welding wire (consumable electrode) pulled out from a wire reel or the like to a welding torch, melts it with electric energy, and performs continuous welding is equipped with a wire feeder that feeds the wire. The welding wir...
