[0002] Due to the large size and weight of large elbows, and the high requirements for welding quality, existing manual welding techniques are difficult to achieve continuous, uniform, and high-quality welds. Moreover, manual welding is labor-intensive and inefficient. With the promotion and application of automatic welding equipment, automatic welding equipment can also weld the arch seams of elbows. However, the position of the elbow cannot be easily moved during welding, otherwise it will easily lead to poor weld formation quality. Therefore, it is necessary to fix the elbow to ensure the quality of the weld formation. Utility Model Content

[0007] As a preferred technical solution of this utility model: the bottom of the support rod is fitted to the mounting base through a connecting plate, and one end of the fastener passes through the connecting plate and is connected to a nut to fix the support rod on the mounting base.

[0008] As a preferred embodiment of this utility model, the distance between the first screw and the second screw on the first support assembly is smaller than the distance between the first screw and the second screw on the second support assembly.

[0009] As a preferred technical solution of this utility model, it also includes a support rod, and the support rod is movably connected to the mounting base by a connection hole.

[0010] As a preferred technical solution of this utility model: the number of connecting holes is multiple, and the number of supporting rods is at least one.

[0011] As a preferred technical solution of this utility model: the mounting base is further provided with a mounting hole in the middle, and the mounting base is fixed on the output shaft of the motor through the mounting hole.

[0012] As a preferred technical solution of this utility model: the mounting base is further provided with an auxiliary fixing groove; wherein, the auxiliary fixing groove is located above the mounting hole, and the connecting hole is located below the mounting hole.

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model.

[0022] Please see Figure 1-5 This utility model provides an embodiment of a fixing device for welding the arch seam of an elbow, comprising a mounting base 1, wherein the mounting base 1 is provided with a first support component 2 and a second support component 3; the first support component 2 is slidably engaged with a first sliding groove 10 provided on the mounting base 1, and the second support component 3 is slidably engaged with a second sliding groove 13 provided on the mounting base 1; by the opposite movement of the first support component 2 and the second support component 3, the upper ends of the first support component 2 and the second support component 3 abut against the inner wall surface of the elbow, thereby fixing the elbow on the mounting base 1.

[0023] In summary, since the first support component 2 and the second support component 3 can slide on the mounting base 1 and be inserted into the interior of the elbow to support the elbow from the back; when the two support components are fixed on the mounting base 1, the elbow can be stably and reliably positioned on the mounting base; based on this, the device can fix the elbow so that the elbow arch joint can avoid the problem of poor arch joint forming quality caused by the elbow position shifting during the welding process; in particular, the structure of the device is simpler, and the elbow can be fixed and removed at the same time by sliding the two support components on the mounting base 1.

[0024] Specifically, such as Figure 5As shown, both the first support assembly 2 and the second support assembly 3 include a fastener 25 and a support rod 22 that slides along the fastener 25. The support rod 22 is provided with a first screw 21, and a sleeve 24 is installed on the first screw 21. When one end of the fastener 25 is inserted into the corresponding groove on the mounting base 1, the slider at the bottom of the fastener 25 is engaged in the groove, preventing the fastener 25 from falling off. Simultaneously, the sleeve 24 rotates clockwise on the first screw 21, which increases the length of the first screw 21, allowing one end of the sleeve 24 to reliably abut against the inner wall of the elbow, thereby improving the support assembly's ability to fix the elbow. Conversely, when the sleeve 24 rotates counterclockwise on the first screw 21, it engages with the elbow, facilitating separation of the elbow from the first support assembly 2 and the second support assembly 3.

[0025] Furthermore, since the support rod 22 is also provided with a second screw 23 parallel to the first screw 21, and the second screw 23 is also equipped with a first sleeve 24, the number of second screws 23 can be increased so that the first support assembly 2 can contact the inner wall of the elbow from two points. Therefore, when the first support assembly 2 and the second support assembly 3 are simultaneously inserted into the elbow, the elbow can be supported from at least four points, allowing the elbow to be stably and reliably positioned on the mounting base 1. The first screw 21 and the second screw 23, after contacting the inner wall of the elbow, are located on both sides of the arch joint. In specific applications, the sleeve 24 is preferably made of copper.

[0026] Furthermore, since the bottom of the support rod 22 is attached to the mounting base 1 via a connecting plate 20, and one end of the fastener 25 passes through the connecting plate 20 and connects to the nut 26, the support rod 22 is fixed to the mounting base 1. Therefore, the support rod 22 can be reliably fixed to the mounting base 1.

[0027] In use: Align one end of the first support component 2 and the second support component 3 with the elbow, then push the first support component 2 and the second support component 3 until the support rod 22 of the first support component 2 abuts against the outer side of one end of the elbow, and the support rod 22 of the second support component 3 abuts against the outer side of the other end of the elbow; then tighten the nut 26 to fix the fastener 25 on the mounting base 1, at which point both ends of the elbow can be fixed; after both ends of the elbow are fixed, rotate the sleeve 24 located inside the elbow. Since both ends of the elbow are fixed, as one end of the sleeve 24 abuts against the inner wall of the elbow, continue to rotate the sleeve 24. As the sleeve 24 extends until it can no longer be rotated, the elbow can be effectively fixed between the two support components.

[0028] Furthermore, the distance between the first screw 21 and the second screw 23 on the first support assembly 2 is smaller than the distance between the first screw 21 and the second screw 23 on the second support assembly 3. Therefore, interference between the sleeves 24 on the two support assemblies when they enter the elbow can be avoided.

[0029] Based on the above solutions, such as Figure 1 and Figure 2 As shown, it also includes a support rod 4, and the support rod 4 is movably connected to the mounting base 1 by a connecting hole 14. Therefore, the support rod 4 can also be used to support the elbow from below the outer wall of the elbow, further improving the stability of the elbow on the mounting base 1.

[0030] Furthermore, since the mounting base 1 is provided with a mounting hole 11 in the middle, and the mounting base 1 is fixed to the output shaft of the motor through the mounting hole 11, the mounting base 1 can be connected to the output shaft of the motor by passing a bolt through the mounting hole 11. Therefore, the mounting base 1 can be installed on the motor. When the motor rotates, it can drive the elbow to rotate as a whole, so as to improve the welding quality of the arch joint by moving the elbow and the welding.

[0031] Since there are multiple connecting holes 14 and at least one support rod 4, the first sliding groove 10 and the second sliding groove 13 are symmetrically arranged on both sides of the mounting hole 11, and the number of the first sliding groove 10 and the second sliding groove 13 is equal; wherein, there are at least three first sliding grooves 10, and the three first sliding grooves 10 are arranged parallel to each other on the mounting base 1, and the structure of the first sliding groove 10 and the second sliding groove 13 is the same. Therefore, when elbows of different specifications are installed, both ends and the interior of the elbow are still fixed by two support components, and the exterior can be connected to the connecting holes 14 at different positions through the support rod 4, so that the support rod 4 can support the elbow from the outside. Preferably, the connecting hole 14 is an internally threaded hole.

[0032] The mounting base 1 is also provided with an auxiliary fixing groove 12; wherein, the auxiliary fixing groove 12 is located above the mounting hole 11, and the connecting hole 14 is located below the mounting hole 11. Thus, after the rod is connected to the auxiliary fixing groove 12, the other end can be pressed against the elbow to fix the elbow from above. It should be noted that after one end of the rod is pressed against the elbow, the outermost end of the rod needs to completely expose the arch seam to facilitate the movement of the welding torch; the only difference between the rod and the second support assembly 3 is that the support rod 22 does not have a first screw 21 and a second screw 23.

[0033] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
