[0061] Embodiment 1

[0062] See also Figures 1 to 5 As shown, the encircling welding device provided by the present application includes a position adjustment mechanism, a first driving component 102 and a welding mechanism 103; the position adjustment mechanism includes an encircling component 104, and the encircling component 104 surrounds the circumference of the object to be welded 101; the welding mechanism 103 is installed on the encircling component 104, and the encircling component 104 is used to support the welding mechanism 103, so that the welding part of the welding mechanism 103 and the gap at the joint between the column (the object to be welded 101) are opposite, thereby realizing welding at this location. Generally speaking, the gap is about 3 mm; and a guide structure is formed between the encircling component 104 and the welding mechanism 103, and the guide structure limits the movement path of the welding mechanism 103 (that is, around the circumference of the object to be welded 101); the first driving component 102 is used to provide a driving force to enable the welding mechanism 103 to move around the circumference of the object to be welded 101, thereby performing circumferential welding on the object to be welded 101.

[0063] The circumferential welding device provided in the present application can realize automatic circumferential welding of a welded object 101 such as a column by providing a position adjustment mechanism, a first drive assembly 102 and a welding mechanism 103, thereby improving welding efficiency and welding quality.

[0064] In an optional scheme of this embodiment, the surrounding component 104 includes an annular base plate 105; annular guide bosses 106 are formed on both sides of the annular base plate 105, and the welding mechanism 103 is correspondingly provided with guide rollers 107, and the rolling portion of the guide roller 107 is provided with a guide groove 108, the guide boss 106 is placed in the guide groove 108, and the guide roller 107 can roll relative to the guide boss 106.

[0065] like Figure 1 and Figure 2As shown, the guide boss 106 is placed in the guide groove 108, and the guide boss 106 can support the guide roller 107, thereby achieving a supporting effect on the welding structure; the guide bosses 106 located on both sides of the annular base plate 105 form an annular guide structure, so that the welding mechanism 103 can move on a circular motion path, and when the guide roller 107 rolls relative to the guide boss 106, the rolling friction force formed between the guide roller 107 and the guide boss 106 is small, making the movement smoother and less stuck.

[0066] Or guide grooves (not shown) are formed on both sides of the annular bottom plate 105, and the welding mechanism 103 is correspondingly provided with guide rollers 107, and the rolling portion of the guide rollers 107 can be placed in the guide grooves and roll relative to the guide grooves. The principle of this structure is the same as that of the above structure, except that the boss structure of the guide boss 106 and the groove structure of the guide roller 107 are interchanged, and the above technical effects can also be achieved, which will not be repeated here.

[0067] In an optional scheme of this embodiment, the first drive assembly 102 includes a first drive device 109, a drive gear 110 and an annular tooth 111 formed on the annular base plate 105; the mounting end of the first drive device 109 is connected to the welding mechanism 103, the driving end of the first drive device 109 is connected to the drive gear 110 to drive the drive gear 110 to rotate, and the drive gear 110 is meshed with the annular tooth 111.

[0068] In this embodiment, when the driving gear 110 rotates under the drive of the first driving device 109, the driving gear 110 also moves along the length direction of the annular tooth 111, thereby driving the first driving device 109 and the welding mechanism 103 to move along the length direction of the annular tooth 111, thereby achieving the technical effect of circumferential movement of the welding mechanism 103 around the column.

[0069] In an optional solution of this embodiment, the position adjustment mechanism further includes a lifting assembly for adjusting the height of the welding mechanism 103 to adapt to different welding heights. Specifically, the lifting assembly includes an annular support plate 113 and a second drive assembly 114, the annular support plate 113 surrounds the circumference of the object to be welded 101 and is spaced apart from the annular bottom plate 105; the second drive assembly 114 is installed on the annular support plate 113, and is used to drive the annular bottom plate 105 to approach or move away from the annular support plate 113 to raise or lower the welding mechanism 103.

[0070] In this embodiment, the annular support plate 113 can be fixed to the ground, and the distance between the annular support plate 113 and the annular bottom plate 105 is variable.

[0090] In an optional solution of this embodiment, the folding cover 148 includes a surrounding portion 153 and a door portion 154; the surrounding portion 153 is formed with an opening, the opening corresponds to the notch 145, and the welded object 101 can enter the surrounding assembly 104 through the opening and the notch 145 in turn; the door portion 154 is hinged to the surrounding portion 153 to cover or expose the opening; the hinge axis 156 between the door portion 154 and the surrounding portion 153 is a telescopic axis.

[0091] In this embodiment, before welding, the opening needs to be opened so that the object to be welded 101 can pass through the opening and the notch 145 in sequence into the surrounding assembly 104; during welding, to prevent the influence of wind, the door portion 154 needs to cover the opening, and the folding cover 148 needs to be extended to a sufficient height and width. Since the hinge shaft 156 between the door portion 154 and the surrounding portion 153 is a telescopic shaft, when the sixth driving device 149 drives the folding cover 148 to extend, the door portion 154 can also be driven to extend.

[0092] In an optional scheme of this embodiment, the protective cover 146 also includes a top cover body 157; the top cover body 157 includes a second support frame 158, a seventh drive assembly 159 and an annular elastic cover 160; the seventh drive assembly 159 is connected to the top of the first support frame 150; the second support frame 158 includes a plurality of support rods 161, the plurality of support rods 161 are radially distributed, and the elastic cover 160 is connected to the plurality of support rods 161; the seventh drive assembly 159 includes a seventh drive device and a transmission gear set, one end of the support rod 161 is connected to the transmission gear set, and the seventh drive device drives the other end of the support rod 161 to swing through the transmission gear set, so that the other end of the support rod 161 is close to or away from the object to be welded 101.

[0093] In this embodiment, strong sunlight exposure may also cause detection interference to the laser weld tracking sensor disposed at the end of the robot arm 125. In order to prevent sunlight exposure, a top cover 157 is disposed on the top of the welding mechanism 103. During the welding process, the movable ends of the plurality of support rods 161 point to the columns, that is, the elastic cover 160 is flipped to the inside and in a horizontal state, and the elastic cover 160 is shielded above the welding mechanism 103. After the welding is completed, the seventh driving device can drive the plurality of support rods 161 to flip outward at the same time to flip the elastic cover 160 to the outside, specifically, it can be flipped to the circumference of the plurality of columns 151 to achieve the folding of the elastic cover 160.

[0094] It should be noted that when the movable ends of the multiple support rods 161 point to the pillars, a accommodating space is formed in the middle, and an accommodating space is also formed in the middle of the annular elastic cover 160. When the pillars are very high, they can pass through the accommodating space in the middle, and a vent is also formed in the accommodating space.

[0095] The protective cover 146 can shield the top and circumference of the welding mechanism 103, allowing the robot to work in a relatively sealed environment, and the welding shielding gas during hydrogen arc welding is not affected by wind; it can also enable the laser weld tracker at the end of the robot arm to detect in a good working environment, greatly improving the detection accuracy.
