no. 1 approach

[0080] figure 1 The rotation exchange device 1 according to the first embodiment of the present invention is shown. The rotary replacement device 1 is used to automatically replace a metal nozzle 11 and a contact tip 12, which are torch components of a welding torch 10 used when welding steel plates or the like by arc welding (see Figure 8 to Figure 21 ).

[0081] The welding gun 10 has a cylindrical gun body 10a, and the cylindrical nozzle 11 is detachably connected to a distal end portion of the gun body 10a by screws.

[0082] The tip side of the nozzle 11 has a tapered shape whose diameter gradually decreases as it approaches the tip opening. On the other hand, on the outer peripheral surface of the base end side of the nozzle 11, a knurling extending in the circumferential direction is formed. The engaged portion 11a.

[0083] That is, the engaged portion 11a is configured such that a large number of tooth portions and tooth groove portions extending along the central...

no. 2 approach

[0205] Figure 22 to Figure 29 The removal unit 4 of the rotation replacement apparatus 1 which concerns on the 2nd Embodiment of this invention is shown. In the second embodiment, only a part of the structure of the disassembly unit 4 and the method of discarding the used contact tips 12 detached from the gun body 10a are different from those of the first embodiment, and other aspects are the same as the first embodiment. , so only the parts different from the first embodiment will be described in detail below.

[0206]The first concave groove 41e is not formed in the thick portion 41b of the first rotating body 41 of the second embodiment, as in the first embodiment.

[0207] In addition, the stopper member 41d is not fitted into the outer peripheral surface of the lower end of the first rotating body 41 as in the first embodiment.

[0208] Further, a contact portion 41f in the shape of a mortar is formed on the upper opening periphery of the through hole 41a of the first ...

no. 3 approach

[0249] Figure 30 to Figure 36 The removal unit 4 of the rotation replacement apparatus 1 which concerns on the 3rd Embodiment of this invention is shown. In the third embodiment, only a part of the structure of the disassembly unit 4 and the method of discarding the used contact tips 12 detached from the gun body 10a are different from those of the second embodiment, and the other aspects are the same as the second embodiment. , so only the parts different from the second embodiment will be described in detail below.

[0250] like Figure 30 and Figure 31 As shown, an annular wall portion 41g that bulges outward and extends upward is provided on the outer peripheral edge portion of the upper end of the thick wall portion 41b on the first rotating body 41 of the third embodiment. On the inner peripheral surface of the upper half of the , four recessed portions 41h which are recessed toward the radially outer side and extend up and down are formed at equal intervals around ...

Abstract

A positioning component (13) is provided on the inner peripheral surface of the first rotating body (41) forming the through hole (41a), and the positioning component (13) is connected with the contact tip (12) received in the through hole (41a). The outer peripheral surface is in contact so that the central axis of the contact tip (12) coincides with the rotation axis (R2), or makes the central axis of the contact tip (12) approach the rotation axis (R2).

Description

technical field [0001] The present invention relates to a rotary replacement device for replacing a nozzle and a contact tip mounted on the tip of a gun body of an arc welding torch. Background technique [0002] Heretofore, for example, Patent Document 1 discloses a rotary replacement device for efficiently replacing torch components such as a cylindrical nozzle and a rod-shaped contact tip attached to the tip of an arc welding torch. The welding gun components are automatically replaced. [0003] The rotary replacement device includes a plurality of changers having a recessed portion open toward the upper end, and each of the changers rotates around a rotating shaft in an up-down direction under the action of a drive motor and a gear meshing mechanism. The rotary replacement device is configured such that, when the welding torch constituting member is to be detached from the gun body, the welding torch constituting member is inserted into the concave portion while the cha...
