The top of the operation rack support (1) is provided with a mounting plate (5) and a lifting screw (6). Although this patent solves the technical problems of low efficiency and long time consumption when changing fixtures during welding training, it cannot simulate welding training of two plates in different postures.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] The present invention relates to a multi-posture welding training support structure, which includes a base 1 and a column 2 vertically fixed on the base 1. The base 1 is a rectangular plate, which can be fixedly connected to the ground by bolts or the like. The column 2 is perpendicular to the base 1 and the ground.

[0028] An adjusting seat 3, a screw 4 installed on the adjusting seat 3 and parallel to the column, and a lifting seat 5 slidably connected to the column 2 are fixed on the column 2. The adjusting seat 3 can be locked and fixed to the column 2 by bolts, etc. The lifting seat 5 has a vertical channel that fits on the column 2 with clearance.

[0029] The screw 4 and the lifting seat 5 are threadedly connected so that when the screw is rotated, the lifting seat 5 can be driven to slide up and down along the column 2. That is, the lifting seat 5 is provided with a threaded channel, and the screw 4 is threadedly connected in the threaded channel. The screw and the lifting seat form a screw and nut mechanism, that is, when the screw is rotated, the lifting seat 5 can be driven to slide up and down along the column 2.

[0030] The adjusting seat is equipped with an adjusting seat drive mechanism that drives the screw to rotate. The specific structure of the adjusting seat drive mechanism is shown in the following embodiment.

[0031] One embodiment of the adjusting seat drive mechanism includes a worm gear mechanism 10 housed within the adjusting seat 3 and a rotating wheel 11 that drives the worm gear mechanism. The rotating wheel 11 is connected to the input end of the worm gear mechanism 10, and the output end of the worm gear mechanism is connected to the screw 4. That is, the worm of the worm gear mechanism is coaxially connected to the rotating wheel, and the worm wheel of the worm gear mechanism is coaxially connected to the screw. When the rotating wheel 11, located outside the adjusting seat, rotates, it drives the worm, worm wheel, and screw 4 to rotate, thereby driving the lifting seat to move up and down.

[0032] In another embodiment of the adjusting seat drive mechanism, the adjusting seat drive mechanism includes a bevel gear transmission mechanism disposed in the adjusting seat body. The bevel gear transmission mechanism includes a first bevel gear coaxially arranged with the rotating shaft of the rotating wheel and a second bevel gear coaxially arranged with the screw. The first bevel gear and the second bevel gear mesh perpendicularly with each other. When the rotating wheel 11 located outside the adjusting seat rotates, it drives the first bevel gear, the second bevel gear and the screw 4 to rotate, thereby driving the lifting seat to move up and down.

[0033] The aforementioned lifting seat, screw, and other mechanisms enable the adjustment of the height position of the plate to be welded held in this application.

[0034] To adjust the posture of the clamped plate to be welded, a first drive rotation mechanism 6 and a second drive rotation mechanism 7 connected to the output end of the first drive rotation mechanism are installed on the lifting base 5. A support plate 8 is installed on the output end of the second drive rotation mechanism 7. The axis of rotation driven by the first drive rotation mechanism 6 and the second drive rotation mechanism 7 are perpendicular to each other. Two sets of clamps 9 for clamping the welding plate are installed on the support plate 8 at intervals. The plate to be welded held by the clamps is perpendicular to the support plate 8.

[0035] Specifically, the first drive rotation mechanism 6 and the second drive rotation mechanism 7 can be commercially available worm gear reducers. The output shaft of the first drive rotation mechanism is horizontally set, and the input ends of the first drive rotation mechanism and the second drive rotation mechanism have external hexagon heads 12 for easy adjustment.

[0036] The rotational attitude along the horizontal axis is adjusted by the action of the external hexagonal head 12 of the first drive rotation mechanism 6, and the rotational attitude perpendicular to the horizontal axis is adjusted by the action of the external hexagonal head 12 of the second drive rotation mechanism 7.

[0037] One embodiment: The clamp 9 for holding the welding plate includes a mounting block 13 with a spherical groove 15 fixed to a support plate 8 and a cover plate 14 covering the mounting block. The mounting block 13 and the cover plate 14 are relatively independent components. The surface of the cover plate 14 facing the mounting block has a spherical groove 16 corresponding to the spherical groove 15. The cover plate has a through hole at the bottom of the spherical groove. A ball head 17 with a connecting rod 18 is installed in the spherical groove and the spherical groove. The connecting rod 18 passes through the through hole and connects to the clamp seat 1. 9. Fixed connection, the diameter of the through hole is larger than the diameter of the connecting rod 18, but smaller than the diameter of the ball head 17. The ball head 17 can swing in the spherical cavity formed by the spherical groove 15 and the spherical groove 16. It is locked by the connection of the mounting block 13 and the cover plate 14 to restrict the swing of the ball head 17. That is, when the bolts of the mounting block 13 and the cover plate 14 are loosened, the ball head 17 (as well as the clamp seat 19, the clamp and the plate to be welded) can swing. When the bolts of the mounting block 13 and the cover plate 14 are tightened, the swing of the ball head 17 is restricted.

[0038] A clamp fixing part 20 and a clamp movable part 21 slidably connected to the clamp base 19 are fixedly installed on the clamp base 19 (the clamp fixing part 20 is provided with a slide rail, and the clamp movable part 21 is provided with a slide groove that cooperates with the slide rail to slide). A lead screw 22 is rotatably connected to the clamp fixing part (the lead screw 22 can only rotate relative to the clamp fixing part and cannot move axially). The lead screw is threadedly connected to the threaded hole of the clamp movable part so that when the lead screw is driven to rotate, the clamp movable part is driven to move closer to or away from the clamp fixing part. That is, the lead screw 22 and the clamp movable part 21 form a lead screw nut mechanism.

[0039] For optimal design, the clamping parts of the clamp fixing part and the clamping part of the clamp moving part are two parallel planes that are perpendicular to the support plate.

[0040] The method of using this utility model's multi-posture welding training support structure (taking plate clamping as an example) is as follows: When simulating welding from a low angle, the plates to be welded are adjusted and clamped on two sets of clamps, so that the two plates are in contact with each other. By adjusting the action of the seat drive mechanism, the lifting seat, the clamps on it, and the plates to be welded are raised to a certain height. By adjusting the first drive rotation mechanism or the second drive rotation mechanism, the two plates to be welded are placed in different postures. When simulating welding from a high angle, the lifting seat, the clamps on it, and the plates to be welded are lowered to a certain height by adjusting the action of the seat drive mechanism. By adjusting the first drive rotation mechanism or the second drive rotation mechanism, the two plates to be welded are placed in different postures.

[0041] In another embodiment, the clamp for holding the pipe fitting includes a mounting block 13 with a spherical groove 15 fixed to a support plate 8 and a cover plate 14 covering the mounting block. The mounting block 13 and the cover plate 14 are relatively independent components. The surface of the cover plate 14 facing the mounting block has a spherical groove 16 corresponding to the spherical groove 15. The cover plate has a through hole at the bottom of the spherical groove. A ball head 17 with a connecting rod 18 is installed in the spherical groove and the spherical groove. The connecting rod 18 passes through the through hole and connects with the lower clamp 23. The lower part is fixedly connected, and the diameter of the through hole is larger than the diameter of the connecting rod 18, but smaller than the diameter of the ball head 17. The ball head 17 can swing within the spherical cavity formed by the spherical groove 15 and the spherical slot 16. It is locked by the connection of the bolts between the mounting block 13 and the cover plate 14 to restrict the swing of the ball head 17. That is, when the bolts between the mounting block 13 and the cover plate 14 are loosened, the ball head 17 (as well as the lower clamp, upper clamp and the pipe to be welded) can swing. When the bolts between the mounting block 13 and the cover plate 14 are tightened, the swing of the ball head 17 is restricted.

[0042] The lower clamp 23 is detachably connected to the upper clamp 24. The upper clamp 24 and the lower clamp 23 have oppositely arranged arc grooves 25 to clamp the pipe. The two sides of the upper clamp 24 and the lower clamp 23 are connected by bolts.

[0043] The multi-posture welding training bracket of this utility model has a reasonable structural design, which is conducive to conveniently adjusting the different postures and positions of two plates to be welded, two pipes to be welded, or pipes and plates, and is conducive to meeting the needs of various welding training.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
