[0035] The specific application of this embodiment 1 is as follows: during the process of plasma arc welding of steel bars 2 at a construction site, the positioning device is used to respectively sleeve and position the two steel bars 2 to be welded inside the two second clamping plates 6. After the sleeve and positioning are completed, the two second clamping plates 6 start to approach each other through the two T-shaped guide grooves 402 respectively opened at the top of the L-shaped positioning bottom plate 401, thereby driving the contact balls 614 respectively arranged inside the two second clamping plates 6 to slide and cooperate on the inclined surface of the trapezoidal plate 403, so as to achieve the desired effect. The movement of the contact ball 614 provides a force to drive the extension rod 613 fixed to the side surface of the contact ball 614, and the hinge seat 604 fixed to one end of the extension rod 613 synchronously moves toward an outer side surface of the U-shaped vertical plate 606 inside the T-shaped groove 603, thereby driving the hinge arm 605 hinged between the hinge seat 604 and the L-shaped bottom plate 608 to synchronously perform an upward hinged rotation, so that the slider 607 moves obliquely upward inside the U-shaped vertical plate 606. When the slider 607 is in the U-shaped When the vertical plate 606 moves upward obliquely inside, the two T-shaped vertical plates 609 fixed on the top of the slider 607 and the lower semicircular clamps 610 fixed on the top of the two T-shaped vertical plates 609 move upward obliquely synchronously, thereby driving the steel bars 2 to be welded, which are respectively supported on the two lower semicircular clamps 610, to move upward obliquely synchronously and gradually approach the inner walls of the two upper semicircular clamps 501 until the surfaces of the two steel bars 2 to be welded are respectively in contact with the inner walls of the two upper semicircular clamps 501 (initial position). At this time, the welding ends of the two steel bars 2 to be welded are in a state of being close to each other (there is a certain small weld gap between the welding ends of the two steel bars 2 to be welded, so as to facilitate plasma arc welding in the later stage). In this way, the two steel bars 2 to be welded are positioned and aligned before welding to ensure that when plasma arc welding is performed on the two steel bars 2 to be welded in the later stage, the steel bars 2 to be welded are in a relatively concentric position, avoiding dislocation during the later welding process and preventing the welding effect from being affected in the later stage.

Specifically, a moving block 615 is fixed on the top of the transverse plate 602, and a first threaded hole 616 is penetrated on one side of the moving block 615; a side plate 404 is fixed on the side of the L-shaped positioning bottom plate 401, and a servo motor 405 is fixed on one side of the side plate 404. A first bidirectional threaded screw rod 406 that is threadedly matched with the first threaded hole 616 is fixed on the output shaft of the servo motor 405, and a circular retaining ring 407 is fixed on the side surface of the first bidirectional threaded screw rod 406.

[0037] The specific application of the present embodiment 2 is as follows: during the use of the positioning device, after the two steel bars 2 to be welded are sleeved and positioned (during the sleeved and positioned fixing process, the two steel bars 2 to be welded are sleeved and inserted into the sleeve tube 612 in turn. During the sleeved and positioned process, the friction between the rubber friction balls arranged inside the sleeve tube 612 and the surface of the steel bars 2 is increased through the mutual contact process between the rubber friction balls and the surface of the steel bars 2, so as to prevent the two steel bars 2 from sliding relative to each other in the two sleeve tubes 612 during the later process of centering adjustment, thereby avoiding the influence on the later plasma arc welding process), the servo motor 405 fixed on one side of the side plate 404 is started to drive the first bidirectional threaded screw 406 fixed on the output shaft of the servo motor 405 to rotate in the first threaded hole 616 penetrated through one side of the two moving blocks 615, so that the two moving blocks 615 rotate relative to each other synchronously. When the two moving blocks 615 rotate synchronously relative to each other, the transverse plate 602 fixed at the bottom of the moving block 615 and the T-shaped slide rail 601 fixed at the bottom of the transverse plate 602 slide in the T-shaped guide groove 402 to limit the circumferential rotation of the two moving blocks 615, so that the two moving blocks 615 synchronously approach each other in a straight line direction at the inner top of the L-shaped positioning bottom plate 401 (when the two moving blocks 615 synchronously approach each other in a straight line direction at the inner top of the L-shaped positioning bottom plate 401, the buffer spring 617 connected and fixed between the hinge seat 604 and the T-shaped guide groove 402, and sleeved and fixed on the side surface of the guide rod 618 can play a certain elastic support and buffering role), thereby providing a driving force for the subsequent centering adjustment process to approach each other, so that it is convenient for construction workers to perform plasma arc welding on the two steel bars 2 during on-site construction, avoiding the phenomenon of misalignment of the two steel bars 2 at the construction site, and improving the welding effect of plasma arc welding; Before plasma arc welding is performed on the two steel bars 2, the plug-in holes 511 respectively opened on the tops of the two H-shaped fixing blocks 510 are plugged into the circumferential side surfaces of the threaded columns 409 respectively fixed on the inner bottoms of the two rectangular grooves 410, until the bottoms of the two H-shaped fixing blocks 510 are respectively fitted with the inner bottoms of the two rectangular grooves 410, and then the two H-shaped fixing blocks 510 are fixed and limited by the threaded rotation between the external nuts and the threaded columns 409. In the process of plug-in and fixation, the two H-shaped plug-in blocks 503 are synchronously plugged and positioned into the two U-shaped vertical baffles 423, respectively, to complete the plug-in fixed installation process between the first clamping plate 5 and the L-shaped positioning base plate 401.

[0039] The specific application of this embodiment 3 is as follows: during the use of the positioning device, after the welding assembly 3 is rotated and installed, when the welding assembly 3 is rotated and installed, the annular groove 302 opened on the outer wall of the rotating ring 301 is first rotated and clamped to the outer peripheral side of the arc-shaped limiting ring 419. After the rotation and clamping are completed, the second bidirectional threaded screw 413 is rotated to drive the two threads to rotate and match the displacement plates 414 on the second bidirectional threaded screw 413 to move relative to each other synchronously, and thereby the two displacement plates 414 are synchronously moved between the second bidirectional threaded screw 413 and the limiting rod 412 through the limiting action between the limiting rod 412 and the two displacement plates 414. 2, the circumferential side surfaces of the two side plates 415 move relative to each other until the arc-shaped positioning plates 416 fixed to the two side surfaces of the two side plates 415 move synchronously to the inside of the annular grooves 303 respectively opened at the two ends of the rotating ring 301, and then the second bidirectional threaded screw 413 stops rotating, thereby completing the assembly and rotation coordination of the entire welding assembly 3, so as to facilitate the plasma arc welding of the butt joint of the two steel bars 2 that have been positioned and fixed in the later stage during the construction process; after the rotation installation of the above-mentioned welding assembly 3 is completed, and the two steel bars 2 to be welded have completed the centering adjustment, a driving motor 420 fixed to one side of the vertical plate 411 is started to drive its output The rotating gear 421 fixed to the shaft rotates, causing the gear ring 304 meshing therewith to rotate, thereby driving the entire welding assembly 3 to rotate circumferentially on the arc-shaped limiting ring 419. Before the welding assembly 3 rotates circumferentially, the telescopic cylinder 305 fixed to the inner wall of the rotating ring 301 is started, driving the plasma arc welding gun 306 fixed to the telescopic end of the telescopic cylinder 305 to move linearly until the welding point of the plasma arc welding gun 306 and the welding ends of the two steel bars 2 after the centering adjustment are in contact with each other. When the welding assembly 3 rotates, the plasma arc welding gun 306 is started (the plasma arc welding gun 306 is a prior art, and its specific The use process will not be elaborated in detail here), so as to perform circumferential plasma arc welding on the two steel bars 2 that have been adjusted to the center, so that construction workers can carry out later construction work, which brings certain convenience to the construction process of construction workers; during the rotational welding process, the welding assembly 3 synchronously drives the two turbine cooling fans 307 symmetrically fixed on the inner wall of the rotating ring 301 to rotate, so as to dissipate the heat at the welding point of the two steel bars 2 during the plasma arc welding process through the centrifugal heat dissipation effect of the two turbine cooling fans 307, thereby preventing the welding point of the two steel bars 2 from being affected by the excessively high welding temperature, thereby improving the welding effect of the whole process.
