Description

Technical Field

[0001] This application relates to the field of workpiece processing technology, and more specifically, to an automatic welding device. Background Technology

[0002] Argon arc welding is a welding technique that uses argon gas as a shielding gas. It is also known as argon gas shielded welding. Argon gas is passed around the arc welding area to isolate the air from the welding area and prevent oxidation of the welding area.

[0003] In current production, when parts are damaged, most repairs are done by manual welding. However, when welding stainless steel parts, it is difficult to ensure that the distance between the welding needle and the part is consistent, resulting in poor product consistency. Summary of the Invention

[0010] Preferably, the connection end between the support plate and the first support rod is an arc-shaped structure, and a retaining ring is provided on the first support rod, the retaining ring being located on the side of the support plate away from the operating table.

[0029] Example

[0030] like Figure 1-4 As shown in the embodiment of this application, the automatic welding equipment includes an operating table 1, a clamping assembly 2, a welding torch 3, a support assembly 4, a drive assembly 5, and a carrier 6. The clamping assembly 2 is used to clamp the welding torch 3, which is connected to an external argon arc welding machine. The support assembly 4 is set on the operating table 1 and is used to support the drive assembly 5. The drive assembly 5 drives the carrier 6 to rotate, and the carrier 6 is used to place parts.

[0031] In use, the part is first placed on the carrier 6, and then the relative position of the welding gun 3 is determined according to the position of the part. The clamping assembly 2 is used to position the welding gun 3. Then the drive assembly 5 drives the carrier 6 to rotate, and the carrier 6 drives the part to rotate. The welding gun 3 welds the rotating part, thus ensuring the consistency of the distance between the welding needle and the part during circumferential welding, and improving the pass rate and welding quality of circumferential welding.

[0032] In this embodiment, the clamping assembly 2 includes a base 7, a main shaft 8, a first fixing clamp 9, a second fixing clamp 10, a support shaft 11, and a third fixing clamp 12. The main shaft 8 is mounted on the base 7. The first fixing clamp 9 is fixed to the main shaft 8 by bolts. The second fixing clamp 10 is fixed to the first fixing clamp 9 by bolts. The second fixing clamp 10 is fixed to the support shaft 11 by bolts. The third fixing clamp 12 is fixed to the support shaft 11 by bolts. The third fixing clamp 12 is used to clamp the welding torch 3.

[0033] In use, the welding torch 3 is held in place by the second fixing clamp 10. After loosening the bolts on the first fixing clamp 9, the first fixing clamp 9 can be moved up and down. After loosening the bolts on the second fixing clamp 10, the support shaft 11 can be moved or rotated, so as to make it easy to adjust the welding torch 3 to the best welding position.

[0034] In this embodiment, the third fixing clip 12 is a pipe clamp, which has the characteristics of convenient installation and high flexibility.

[0035] In this embodiment, the support assembly 4 includes a base plate 13, a support plate 14, a first support rod 15, a second support rod 16, and a connecting rod 17. The base plate 13 is disposed on the operating table 1, the support plate 14 is disposed on the base plate 13, the first support rod 15 and the second support rod 16 are both disposed on the support plate 14, the support plate 14 is obliquely mounted on the first support rod 15, the drive assembly 5 is disposed at the upwardly oblique end of the support plate 14, and the connecting rod 17 is disposed at the downwardly oblique end of the support plate 14. The end of the connecting rod 17 away from the support plate 14 is connected to the second support rod 16.

[0036] In this embodiment, the connection end between the support plate 14 and the first support rod 15 is an arc-shaped structure. The arc-shaped structure design makes it easy to install the support plate 14 on the first support rod 15. A retaining ring 18 is provided on the first support rod 15. The retaining ring 18 is located on the side of the support plate 14 away from the operating table 1. The retaining ring 18 is used to limit the position of the support plate 14.

[0037] In this embodiment, the second support rod 16 is threaded to the base plate 13, and the threaded connection facilitates the assembly and disassembly of the second support rod 16 and the base plate 13.

[0038] In this embodiment, the length of the portion of the support plate 14 above the first support rod 15 is greater than the length of the portion of the support plate 14 below the first support rod 15. The connecting rod 17 is threadedly connected to the support plate 14. The end of the connecting rod 17 away from the support plate 14 has an arc-shaped locking block 19, which is disposed on the second support rod 16.

[0039] When assembling the support plate 14, the lever principle is used. The part of the support plate 14 above the first support rod 15 tends to move downward, and the part of the support plate 14 below the first support rod 15 tends to move upward. The part of the support plate 14 below the first support rod 15 is limited to the second support rod 16 by the connecting rod 17. Therefore, it is not necessary to fix the support plate 14 to the first support rod 15 or the second support rod 16 to the connecting rod 17, which improves the convenience of overall assembly and disassembly.

[0040] In this embodiment, the drive assembly 5 includes a motor 20, a drive wheel 21, a driven wheel 22, and a synchronous belt 23. The motor 20 is mounted on the support assembly 4 and drives the drive wheel 21 to rotate. The driven wheel 22 is rotatably mounted on the support assembly 4. The synchronous belt 23 is disposed between the drive wheel 21 and the driven wheel 22. Both the drive wheel 21 and the driven wheel 22 are synchronous belt pulleys. The carrier 6 is disposed on the driven wheel 22 and rotates synchronously with the driven wheel 22.

[0041] In use, the motor 20 drives the drive wheel 21 to rotate. With the cooperation of the drive wheel 21, the driven wheel 22 and the timing belt 23, the driven wheel 22 drives the carrier 6 to rotate.

[0042] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
