All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

The embodiment of the invention provides a welding and positioning tool and a welding and positioning method, which can solve the problems that the scribing positioning and adjusting process is complicated and the welding precision is difficult to ensure in the related technology.

Referring to fig. 2, it can be known that the welding and positioning tool provided in this embodiment is used for welding a plurality of first workpieces 4 to a same tubular second workpiece 5, and the positions of the first workpieces 4 and the second workpieces 5 need to be repeatedly adjusted in the conventional scribing and positioning process. In this embodiment, the first workpiece 4 is a titanium alloy block, and the second workpiece 5 is a titanium alloy pipe. The welding and positioning device can also be used for welding and positioning the second workpiece 5 made of the section steel made of other materials.

Referring to fig. 1 and fig. 3, a welding and positioning tool provided in an embodiment of the present invention may include: the positioning device 1 is provided with a second limiting hole 112 and a plurality of first limiting holes 111, and the first limiting holes 111 are used for embedding the first workpiece 4; and one end of the limiting block 2 is embedded in the second limiting hole 112, and the other end of the limiting block 2 is embedded in the second workpiece 5. Since the plurality of first limiting holes 111 are formed in the positioning device 1, the relative positional relationship between the first workpieces 4 is ensured by fitting the first workpieces 4 into the corresponding first limiting holes 111. The second limiting hole 112 is formed in the positioning device 1, so that the limiting block 2 can be embedded, and the position between the limiting block 2 and the first workpiece 4 installed on the first limiting hole 111 is relatively fixed. When the second workpiece 5 is mounted, the stopper 2 is embedded in the second workpiece 5. The second workpiece 5 is fixed relative to the positioning device 1. Thereby ensuring the determination of the relative position of the first workpiece 4 and the second workpiece 5. The welding accuracy between the first workpiece 4 and the second workpiece 5 in the welding process is improved. Compared with a scribing method for positioning the parts, in the embodiment, the first workpiece 4 can be embedded into the corresponding hole to complete positioning, and the process of repeated adjustment is conveniently omitted in the positioning process. The first limiting hole 111 and the limiting block 2 can also prevent the first workpiece 4 and the second workpiece 5 from moving in the welding process. The welding precision is improved. So as to avoid the subsequent large machining amount caused by large welding error.

In this embodiment, the first workpiece 4 is a rectangular titanium alloy block, and in order to adapt to the installation of the first workpiece 4, the first limiting hole 111 is provided in a hole shape corresponding to the shape of the first workpiece 4, and the outline of the first limiting hole 111 is larger than that of the first workpiece 4, so that when the first workpiece 4 is installed in the first limiting hole 111, an assembly gap is left between the first workpiece 4 and the inner wall of the first limiting hole 111. In this embodiment, the assembly gap is 0.4mm, and the unilateral gap is 0.2mm. In other embodiments, the fitting clearance may be selected to be a suitable size according to the size of the first workpiece 4.

In this embodiment, the welding and positioning tool includes three pressing devices 3, and in other embodiments, an appropriate number of pressing devices 3 may be selected and set according to the length of the second workpiece 5. The pressing devices 3 are arranged at intervals along the length direction of the positioning device 1, and the pressing mounting seats 31 can slide along the length direction of the positioning device 1, so that the interval distance between the pressing mounting seats 31 can be adjusted. When the length of the second workpiece 5 is relatively short, the pressing mounting seats 31 are made to approach each other by sliding the pressing mounting seats 31; when the length of the second workpiece 5 is relatively long, the pressing mounting seats 31 are slid to increase the distance between the pressing mounting seats 31, so that the end parts of the second workpiece 5 are pressed, and the pressing effect on the second workpiece 5 is improved. The pressing mounting seat 31 is connected with the positioning device 1 in a sliding mode, and therefore the pressing mounting seat is particularly suitable for pressing section steel parts with various length specifications.

Wherein, the pressing mounting seat 31 is detachably connected with the positioning device 1, and when a second workpiece 5 with a larger length is processed, a plurality of pressing mounting seats 31 can be arranged on the positioning device 1. When the length of the second workpiece 5 is short and the full number of the pressing devices 3 is not required to be pressed, the pressing devices 3 can be detached from the positioning device 1, so that more welding operation space is reserved for welding. In this embodiment, the pressing mounting seat 31 is arranged as a frame structure and sleeved outside the positioning device 1, so that the pressing mounting seat 31 is slidably mounted on the positioning device 1. In other embodiments, a slide rail may be provided on the positioning device 1, and a slide block corresponding to the slide rail may be provided on the pressing installation seat 31.

That is, in the present embodiment, the adjusting bolt 321 is screwed to move up and down, thereby pressing the second workpiece 5. In other embodiments, a cushion structure may be further disposed at the bottom of the adjusting bolt 321 to reduce damage to the second workpiece 5 during pressing the second workpiece 5.

The notches 33 formed at the head and tail ends of the mounting seat body 311 are used for fixing the nuts 312, compared with the situation that threaded holes are directly formed in the mounting seat body 311, the strength requirement on the mounting seat body 3111 is lower, and even if the mounting seat body 311 is a hollow frame structure, the effect that the adjusting bolts 321 move up and down can be met through the fixed connection nuts 312. By providing the notch 33 in the mount base main body 311 and attaching the nut 312 to the notch 33, the structure of the mount base main body 311 can be simplified. And reduces the risk of the nut 312 disengaging the mount body 311 when subjected to radial forces.

That is, by inserting the positioning plate 11 into the position-limiting passage defined by the mounting seat body 311, since the width of the position-limiting passage is equal to the width of the positioning plate 11, the mounting seat body 311 is prevented from deflecting relative to the positioning plate 11. Deflection of the press member 32 during welding is avoided.

Referring to fig. 1 and 2, in some alternative embodiments, the first position-limiting hole 111 penetrates through the positioning plate 11, a position-limiting support portion 12 is connected to a bottom of the positioning plate 11, and the position-limiting support portion 12 is located below the first position-limiting hole 111.

The strength of the positioning device 1 is improved by the bottom beams 121 arranged at intervals. By setting the extending direction of the bottom beam 121 to be the same as the arrangement direction of the first stopper holes 111, the plurality of first workpieces 4 can be supported more favorably. In this embodiment, the bottom of the frame structure formed by the mounting seat body 311 is hooped on the bottom of the bottom beam 121, and when the pressing member 32 presses the second workpiece 5 downward, the bottom of the frame structure of the mounting seat body 311 bears the pressing force transmitted to the bottom beam 121.
