Description

Technical Field

[0001] The utility model relates to the technical field of pipe welding equipment, in particular to automatic pipe welding equipment. Background Art

[0002] In high-efficiency tank heat exchangers, in order to circulate refrigerants (such as Freon), most of them need to be equipped with fluorine-circuit pipes in the tank, that is, a copper tube is inserted into the high-efficiency tank, and the gaseous Freon enters the tank through the copper tube and circulates in the tank to achieve the effect of heat exchange. For example, a high-efficiency shell-and-tank heat exchanger disclosed in Chinese patent CN207163267U specifically discloses that "the fluorine outlet pipe penetrates the cylinder from the upper end cover, and the bottom of the fluorine outlet pipe is provided with an inclined inlet end at the bottom of the cylinder, and the upper outlet end is at the upper end of the upper end cover." This is what is mentioned above, that is, a whole pipe is inserted into the tank, and this kind of pipe is generally made of copper pipe. The cost of copper pipe is much higher than that of ordinary iron pipe. In fact, the pipe mainly serves as the circulation of Freon, so the cost of using iron pipe will be much lower than that of using copper pipe completely, and it will not affect the circulation performance of the medium.

[0003] When an iron pipe is used as a circulation pipe, it is necessary to weld the iron pipe to the end cover of the tank body in advance to ensure the sealing problem and facilitate the subsequent installation and processing; if manual welding is used, problems such as low processing efficiency and uneven welding quality will occur. Therefore, it is necessary to provide an automated pipe welding equipment to improve welding efficiency and reduce costs. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0024] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to the other element and integrated therewith, or there may be an intermediate element. The terms "mounted", "one end", "the other end" and similar expressions used herein are for illustrative purposes only.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the relevant listed items.

[0026] refer to Figure 1-4 The utility model provides an automatic pipe welding device, comprising an operating table 1, and a supporting mechanism 2, a positioning mechanism 3 and a welding mechanism 4 arranged on the operating table 1; the positioning mechanism 3 is located above the supporting mechanism 2, and the welding mechanism 4 is arranged on one side of the positioning mechanism 3; the supporting mechanism 2 includes a supporting seat 20. In this embodiment, the supporting seat 20 is used to support the pipe fitting to be welded and the end cover of the high-efficiency tank. The supporting seat 20 is rotatably connected to the operating table 1. When the supporting seat 20 rotates relative to the operating table 1, it can drive the end cover and the pipe fitting to rotate together, thereby completing the welding work; the positioning mechanism 3 includes a first driving member 30 (such as a cylinder, or an oil cylinder). Cylinder) and positioning column 31, there is a gap between the positioning column 31 and the support seat 20 for placing the pipe fitting. Specifically, one end of the positioning column 31 is connected to the output end of the first driving member 30, and the other end is extended toward the support seat 20, and there is a certain gap between the support seat 20. During welding, the pipe fitting is placed between the support seat 20 and the positioning column 31, and the first driving member 30 can drive the positioning column 31 to reciprocate in the direction of the support seat 20; the welding mechanism 4 includes a second driving member 40 (such as a cylinder or an oil cylinder) and a welding gun 41, and the second driving member 40 can drive the welding gun 41 to reciprocate in the direction of the support seat 20.

[0027] The automatic pipe welding equipment provided by the utility model, when welding, first put the end cover of the high-efficiency tank with welding on the support seat 20, and then put the pipe vertically on the end cover (the so-called vertical is relative to the end cover). Figure 1(from the first perspective in the figure); then the first driving member 30 drives the positioning column 31 to move toward the support seat 20 until the positioning column 31 abuts against the pipe fitting. At this time, the pipe fitting can be clamped, that is, the pipe fitting is fixed between the positioning column 31 and the support seat 20, avoiding the pipe fitting from being misaligned during welding, which causes the welding gun 41 to weld to an invalid position or even the workpiece to be scrapped. The fixing mentioned here means that the pipe fitting can be in a relatively fixed state, not completely immobile, because during the welding process, the pipe fitting will rotate with the support seat 20, so the pipe fitting is not in a completely immobile state. After the pipe fitting is relatively fixed, the second driving member 40 drives the welding gun 41 to move toward the support seat 20 until the welding gun 41 contacts the connection between the pipe fitting and the end cover. At this time, the welding gun 41 starts welding. While welding, the support seat 20 rotates, synchronously driving the pipe fitting and the end cover to rotate together. After all the connection points between the pipe fitting and the end cover are welded, the support seat 20 stops rotating. At this time, the welded workpiece is removed and the next step can be entered.

[0028] The automatic pipe welding equipment provided by the utility model has the following beneficial effects:

[0029] First, by providing the positioning mechanism 3, the positioning mechanism 3 can clamp and fix the pipe during welding, eliminating the need for manual fixation and resulting in a better fixing effect;

[0030] Second, by providing a rotatable support seat 20 and a welding mechanism 4, automated operation is achieved during the pipe welding process. Compared with manual welding, the welding quality is higher and the welding efficiency is also higher.

[0031] refer to Figure 1-3 In a preferred embodiment, the positioning mechanism 3 further includes a fixing frame 32 and a sliding assembly 33 provided on the fixing frame 32. One end of the fixing frame 32 is connected to the operating table 1, and the other end extends upward relative to the operating table 1. The fixing frame 32 is spaced apart on one side of the support base 20. The first driving member 30 and the positioning column 31 are located above the support base 20 (the above / below mentioned here refers to the above). Figure 1 From the first perspective, that is Figure 1 The first driving member 30 and the positioning post 31 are slidably connected to the fixing frame 32 via a sliding assembly 33. The positioning post 31 can move closer to or further away from the support base 20 when sliding on the fixing frame 32. By sliding the positioning post 31 up and down, it is easy to adapt to pipes of different lengths.

[0032] refer to Figure 2 and 3In a preferred embodiment, the sliding assembly 33 includes a first slide rail 330 and a slide seat 331. The first slide rail 330 is disposed on the fixing frame 32 and extends along the height direction of the fixing frame 32 (referring to the figure, the so-called height direction refers to Figure 3 In the up and down directions); in this embodiment, there are preferably two first slide rails 330, and the two slide rails are relatively spaced apart and arranged on the fixed frame 32 for better stability. The sliding seat 331 is slidably connected to the first slide rail 330. The sliding seat 331 is also connected to the first drive member 30. Specifically, one side of the sliding seat 331 is connected to the slide rail, and the side of the sliding seat 331 facing away from the first slide rail 330 is connected to the first drive member 30. The output end of the first drive member 30 is connected to the positioning column 31, and the positioning column 31 can move up and down on the first slide rail 330 through the sliding seat 331. Therefore, when the sliding seat 331 slides up and down on the first slide rail 330, it naturally drives the positioning column 31 to move up and down synchronously, so that the positioning column 31 is close to or away from the support seat 20. When the lengths of the pipes to be welded are different, the gap between the positioning column 31 and the support seat 20 can be adjusted by moving the sliding seat 331 up and down, which makes the operation more convenient.

[0033] refer to Figure 1 and 2 In a preferred embodiment, a limit block 34 is respectively provided at both ends of the first slide rail 330, one end of the limit block 34 is connected to the fixed frame 32, and the other end is protruding outward relative to the fixed frame 32; when the sliding seat 331 moves up and down along the first slide rail 330, its two ends can respectively abut against the limit block 34; specifically, the limit block 34 limits the sliding distance of the sliding seat 331, and by providing a limit block 34 at the upper and lower ends of the first slide rail 330, when the sliding seat 331 slides to the highest point, it abuts against the limit block 34 provided at the upper end; when the sliding seat 331 slides to the lowest point, it abuts against the limit block 34 provided at the lower end.

[0034] refer to Figure 1-3 In a preferred embodiment, the welding mechanism 4 further includes a guide assembly 42 , the welding gun 41 is connected to the guide assembly 42 , and the second driving member 40 can drive the welding gun 41 to move along the guide assembly 42 .

[0035] refer to Figure 1-3In a further preferred embodiment, the guide assembly 42 is tilted toward the support base 20. When the second drive member 40 drives the welding gun 41 to move back and forth along the tilted direction of the guide assembly 42, the welding gun 41 can move closer to or further away from the support base 20. Before welding, the welding angle of the welding gun 41 can be manually adjusted in advance. During welding, the second drive member 40 drives the welding gun 41 along the tilted direction of the guide assembly 42, specifically toward the support base 20, until the welding gun 41 contacts the pipe to be welded. When the welding work is completed, the second drive member 40 drives the welding gun 41 to move away from the support base 20.

[0036] refer to Figure 2 and 3 In a preferred embodiment, the guide assembly 42 includes a mounting plate 420, a second slide rail 421, and a slider 422, which are connected in sequence. The welding gun 41 and the second driving member 40 are respectively connected to the slider 422. The second driving member 40 can drive the welding gun 41 to reciprocate on the second slide rail 421 via the slider 422. In this embodiment, the mounting plate 420 can be fixed to the operating table 1 via the fixing bracket 32, saving a certain amount of installation space. The second slide rail 421 is disposed on the mounting plate 420 and extends along the length of the mounting plate 420. The mounting plate 420 and the second slide rail 421 are both inclined toward the support base 20. The bottom of the slider 422 is slidably connected to the second slide rail 421. The surface of the slider 422 is connected to the welding gun 41. The output end of the second driving member 40 is connected to the side of the slider 422. Therefore, when the second driving member 40 drives the slider 422 to move along the second slide rail 421, it also drives the welding gun 41 to move synchronously.

[0037] In a preferred embodiment, the support mechanism 2 also includes a motor (not shown), which is located at the bottom of the operating table 1 and connected to the support base 20. The motor can drive the support base 20 to rotate on the operating table 1; during welding, the motor can drive the pipe to rotate through the support base 20.

[0038] refer to Figure 4 In a preferred embodiment, the operating platform 1 is further provided with a plurality of interconnected protective plates 10. Each of the protective plates 10 is fixed to the operating platform 1 at one end and protrudes upward relative to the operating platform 1 at the other end. The protective plates 10 are disposed around the support mechanism 2, positioning mechanism 3, and welding mechanism 4. The protective plates 10 primarily protect the equipment, preventing other factors from interfering with the welding process in the welding area.

[0039] refer to Figure 4In a preferred embodiment, a guide rod 11 is further provided on the operating table 1. The guide rod 11 is spaced apart on one side of the support seat 20, and the guide rod 11 extends along the length direction of the operating table 1. Specifically, the support seat 20 is spaced apart between the fixing frame 32 and the guide rod 11. A protective door 12 is provided on the guide rod 11. The protective door 12 is slidably connected to the guide rod 11, which can further reduce friction and facilitate operation. In this embodiment, the protective door 12 mainly serves as a barrier between the welding area and the outside, preventing the strong light emitted by the welding gun 41 during welding operations from causing damage to the human eye, and also preventing the flame from splashing when the welding gun 41 is operating. There is a gap between both sides of the protective door 12 and the protective plate 10, so as to provide the operator with a certain operating space, making it convenient for the operator to place the pipe to be welded and to adjust the welding angle of the welding gun 41.
