The invention disclosed in Publication No. 31218 is known. Figure 2 and Figure 3 of this publication are Figure 1 of the attached drawings of this application,
The structure will be explained with reference to FIG. FIG. 1 is a front view of the welding heads 8A, 8B, which are connected by a hinge 10, surround a pipe 11 to be welded and are fixed to the pipe 11 by a tightening bolt 14. FIG. 2 shows a cross section taken along the line AA in FIG. 1, and the rotating portion 13 is formed of drive rings (each semicircular) 13A and 13B including toothed portions forming a worm wheel 18. As shown in FIG. The rotating portion 13 is held by outer bearings 12A, 12B fixed to the welding heads 8A, 8B, and clasps 14A, 14B fixed to the bearings 12A, 12B with bolts 15.

Reference numeral 14B is a bearing liner for the rotating part 13, and collar parts 16A and 16B prevent the rotating part 13 from slipping out. The worm wheel 18 meshes with a worm 22 driven by a drive device 19 and is rotationally driven by this worm. The welding torch, wire reel, wire supply device, etc. (not shown) are in this rotating part 1.

される処である。 This rotating part 13 consists of half drive rings 13A and 13B having a worm wheel 18, and the teeth of the worm wheel 18 are manufactured from the half block drive rings 13A and 13B by gear cutting and machining. When the sliding surfaces and teeth become worn, they must be replaced with new ones. This drive ring has a special shape as shown in the figure, and the manufacturing work such as adjusting the tooth pitch when splitting it in half is time-consuming.It has a simple structure and can be easily and inexpensively replaced with a new one. This is what is required.

品交換容易な構造を提案することを目的とする。 This invention eliminates these drawbacks by adopting a combination of a commercially available spur gear and pinion that does not require any difficulty in machining the worm and worm wheel combination, and in addition, the sliding member serving as the bearing portion is a sliding member whose primary purpose is sliding. The purpose of the present invention is to propose a structure in which the spur gear is assembled to the negative surface and parts are easily replaced.

より管11の突き合せ周自動溶接をする。 The structure of the device according to the present invention will be explained with reference to the drawings. The welding heads 1A, 1B are formed so that they surround the pipe 11 with a hinge 10 and are fixed to the pipe 11 by tightening bolts 31, or can open the pipe 11. In this invention, the tsuba 32
Inner liner 2 with B and key-shaped radial cross section
B is connected to the welding head 1B by a bolt 8, and its inner surface is formed to have a semi-cylindrical surface 33B. Also, an outer liner 3B, approximately key-shaped in radial section, with semi-cylindrical surfaces 34B, 35B is fixedly connected to the welding head 1B by bolts 9. In the space formed by the inner liner and the outer liner, a slide ring 4B having a substantially Z-shaped radial cross section is positioned so as to be freely rotatable and slidable between the inner liner and the outer liner. A semi-circular spur gear 5B is connected to this slide ring 4B with a countersunk screw 6. This slide ring 4B, spur gear 5B and slide ring 4A
and spur gear 5A (not shown).
7 is formed. Spur gears 5A and 5B are pinion 3
6 and is rotated by a drive device (not shown).
A welding torch, a wire supply device, a wire reel, etc. are attached to the left side surface of the slide ring 4B or 4A in FIG.

ものである。 By carrying out this invention, even if the slide rings 4A, 4B, outer liners 3A, 3B, inner liners 2A, 2B, etc. wear out due to the rotation of the rotating part 37 while sliding, they can be manufactured by only lathe machining. It can be easily and inexpensively replaced by simply replacing the parts. Further, the gear 5B hardly needs to be replaced, but even if it is replaced, a commercially available spur gear can be purchased, and the price and maintenance costs of the device can be kept very low. This is because the rotating part is formed by a combination of a spur gear and a slide ring.
