Description

Technical Field

[0001] This utility model relates to the field of steel pipe welding technology, specifically to automatic welding equipment for steel pipe processing. Background Technology

[0002] Steel pipe welding equipment is a specialized device for welding steel pipes. It improves welding efficiency, ensures welding quality, and adapts to the welding needs of steel pipes of different specifications. The equipment employs an arc-shaped clamp or U-shaped tray design, enabling quick assembly and disassembly through lateral sliding joints, accommodating steel pipes of varying outer diameters. Some units are equipped with hydraulic cylinders for height adjustment, ensuring the steel pipe's center is horizontally aligned. A rotating frame drives a lifting mechanism, which, in conjunction with front / rear support rollers, ensures stable rotation of the steel pipe, allowing the welding head to perform the welding.

[0003] In the field of steel pipe welding, existing steel pipe welding equipment places the steel pipe on a rotating shaft during welding. The shaft drives the steel pipe to rotate, thus achieving circumferential welding. This requires the two sets of steel pipes to rotate synchronously during welding. If the two sets of steel pipes do not rotate synchronously, it will affect the welding effect. Utility Model Content

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Given that the existing steel pipe welding devices described above or in the prior art can affect the welding effect of the steel pipes if the two sets of steel pipes rotate out of sync.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] Automatic welding equipment for steel pipe processing, characterized in that it includes:

[0008] The welding base includes a steel pipe body disposed above the welding base, a steel pipe placement assembly disposed on the top of the welding base for placing the steel pipe body, and an annular welding assembly disposed in the middle of the welding base for welding the steel pipe body.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1

[0030] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 This is the first embodiment of the present invention, which provides an automatic welding device for steel pipe processing, comprising:

[0031] The welding base 1 includes a steel pipe body 5 disposed above the welding base 1, a steel pipe placement assembly 3 disposed on the top of the welding base 1 for placing the steel pipe body 5, and an annular welding assembly 2 disposed in the middle of the welding base 1 for welding the steel pipe body 5.

[0032] The annular welding assembly 2 includes an annular support 201 disposed in the middle of the welding base 1, an annular guide rail 202 disposed on the inner wall of the annular support 201, and a welding head 203 slidably mounted on one side of the annular guide rail 202.

[0033] Specifically, the annular welding assembly 2 also includes a guide rail slider 204 that is slidably installed at the connection between the welding head 203 and the annular guide rail 202, with the axis of the welding head 203 facing the steel pipe placement assembly 3.

[0034] Furthermore, the welding head 203 can rotate inside the annular guide rail 202 via the guide rail slider 204, thereby enabling the welding head 203 to perform circumferential welding around the steel pipe body 5 placed inside the steel pipe placement assembly 3 without moving the steel pipe body 5.

[0035] Specifically, the steel pipe placement assembly 3 includes a liftable steel pipe support frame 301 mounted on the top of the welding base 1, a wedge-shaped placement block 305 fixed to the inner wall of the steel pipe support frame 301, and a steel pipe fixing assembly 4 mounted on the top of the steel pipe support frame 301.

[0036] Furthermore, the steel pipe body 5 is placed between two sets of wedge-shaped placement blocks 305. Since the two sets of wedge-shaped placement blocks 305 are symmetrically arranged with their surfaces inclined, under the action of gravity, the vertical center line of the steel pipe body 5 is located at the center of the steel pipe support frame 301.

[0037] Specifically, the steel pipe placement assembly 3 also includes lifting sliders 302 fixedly welded to the left and right sides of the steel pipe support frame 301, guide rods 303 passing through the inside of two sets of lifting sliders 302, and lifting screws 304 installed inside the middle set of lifting sliders 302 through threaded sleeves.

[0038] Furthermore, when the lifting screw 304 rotates, it can drive the lifting slider 302 connected to it to slide through the screw sleeve, and the remaining lifting slider 302 can slide on the guide rod 303, which guides the steel pipe support frame 301.

[0039] In use, the user places the two sets of steel pipe bodies 5 on the front and rear sets of steel pipe placement components 3 respectively. Under the action of gravity, the vertical center line of the steel pipe body 5 is located at the center of the steel pipe support frame 301. The two sets of steel pipe bodies 5 abut against each other, and the welding position is set below the welding head 203. Then, the steel pipe body 5 can be fixed by the steel pipe fixing component 4. At this time, the two sets of steel pipe bodies 5 are in contact with each other. Then, the welding head 203 can rotate inside the annular guide rail 202 through the guide rail slider 204, so that the welding head 203 can perform circumferential welding around the steel pipe body 5 placed inside the steel pipe placement component 3 without moving the steel pipe body 5.

[0040] In summary, the automatic welding equipment for steel pipe processing, through the set annular welding assembly 2, allows the welding head 203 to rotate inside the annular guide rail 202 via the guide rail slider 204. This enables the welding head 203 to perform circumferential welding around the steel pipe body 5 placed inside the steel pipe placement assembly 3, without the need to rotate the steel pipe body 5. This avoids the asynchronous rotation of the two sets of steel pipe bodies 5 affecting the welding of the two sets of steel pipe bodies 5.

[0041] Example 2

[0042] Please see Figure 2 , Figure 3 and Figure 4 This is the second embodiment of the present invention, which provides an improved design for an automatic welding equipment for steel pipe processing.

[0043] Specifically, the steel pipe fixing component 4 includes a fixing bracket 405 welded to the top of the steel pipe support frame 301. The fixing bracket 405 and the wedge-shaped placement block 305 are positioned in a one-to-one correspondence. The two wedge-shaped placement blocks 305 are symmetrically arranged about the vertical center line of the steel pipe support frame 301.

[0044] Furthermore, the two symmetrically distributed wedge-shaped placement blocks 305 can move the steel pipe body 5 downwards, so that under the action of gravity, the vertical center line of the steel pipe body 5 is located at the center of the steel pipe support frame 301.

[0045] Specifically, the steel pipe fixing assembly 4 also includes a fixing screw 402 threadedly connected to the middle of the fixing bracket 405, a fixing knob 403 fixed to the top of the fixing screw 402, a mounting bracket 401 rotatably mounted to the bottom of the fixing screw 402, and a support roller 404 rotatably mounted inside the mounting bracket 401.

[0046] Furthermore, after rotating the fixing screw 402, the bottom of the fixing screw 402 can push the mounting bracket 401 to move downward, and the bottom end face of the support roller 404 is lower than the bottom end face of the mounting bracket 401.

[0047] Specifically, the vertical plane containing the vertical center line of the support roller 404 and the steel pipe support frame 301 coincides with each other, and the steel pipe placement assembly 3 is symmetrically arranged about the front and rear of the annular welding assembly 2.

[0048] Furthermore, the support roller 404 comes into contact with the steel pipe body 5, thereby clamping and fixing the steel pipe body 5 through the support roller 404.

[0049] Specifically, the bottom of the fixed screw 402 is rotatably connected to the mounting bracket 401 via a bearing, and the bottom of the lifting screw 304 is fixed with the power output end of the screw motor.

[0050] Furthermore, the lead screw motor is installed inside the welding base 1. The power output end of the lead screw motor can drive the lifting lead screw 304 to rotate. After the lifting lead screw 304 rotates, the height of the steel pipe placement assembly 3 can be adjusted so that the axis of the steel pipe body 5 placed on the steel pipe placement assembly 3 coincides with the axis of the annular bracket 201.

[0051] In use, the lead screw motor is installed inside the welding base 1. The power output end of the lead screw motor can drive the lifting lead screw 304 to rotate. After the lifting lead screw 304 rotates, the height of the steel pipe placement assembly 3 can be adjusted so that the axis of the steel pipe body 5 placed on the steel pipe placement assembly 3 coincides with the axis of the annular bracket 201. After the steel pipe body 5 is placed above the steel pipe support frame 301, the fixing knob 403 can be rotated. The fixing knob 403 drives the fixing screw 402 to rotate. The bottom of the fixing screw 402 can push the mounting bracket 401 to move downward. The bottom end face of the support roller 404 is lower than the bottom end face of the mounting bracket 401, so that the support roller 404 and the steel pipe body 5 come into contact with each other, and the steel pipe body 5 is clamped and fixed by the support roller 404.

[0052] In summary, by having the left and right symmetrical wedge-shaped placement blocks 305 inside the steel pipe placement assembly 3 cooperate with the support rollers 404, the fixing screw 402 can be rotated to push the mounting bracket 401 to move downwards, and the support rollers 404 can come into contact with the steel pipe body 5, thereby clamping and fixing the steel pipe body 5.
