[0047] When the right side of the flange is attached to the left side of the abutting column 321, the flange is located between the four abutting square rods 323, when the vertical rod is sleeved on the inner supporting plate 34 and the outside of the conical head block 352, the operator manually rotates the one-way screw rod 351, so that the one-way screw rod 351 pushes the vertical rod to move right through the conical head block 352, so that the right side of the vertical rod is attached to the left side of the flange.

[0048] Then the operator manually rotates the rotating disc 333, the rotating disc 333 drives the threaded rod 331 to move right, the threaded rod 331 synchronously pushes the three inner supporting plates 34 away from the axis of the threaded rod 331 through the connecting plate 332, so that the inner supporting plates 34 are abutted on the inner side of the vertical rod, so that the vertical rod is centered and clamped, and then the vertical rod is coaxially arranged with the guide column 42.

[0049] It should be noted that when the vertical rod is a cylindrical rod, the inner supporting plate 34 is in line contact with the inner side of the cylindrical rod, and when the vertical rod is a hexagonal rod, the inner supporting plate 34 is in surface contact with the inner side of the hexagonal rod, so that the inner supporting plate 34 can center and clamp the two kinds of vertical rods, and ensure the stability of the alignment.

[0050] The rotating disc 333 rotates at the same time to drive the end face threaded disc 362 to rotate synchronously through the positioning screw 334, the end face threaded disc 362 drives the moving sleeve 322 to move towards the flange through the feeding block 327 and the telescopic rod 326, so that when the inner supporting plate 34 abuts against the vertical rod, the moving sleeves 322 of the front, lower, rear parts drive the abutting square rods 323 to abut against the outer side of the flange, the abutting square rod 323 of the upper part drives the drawer box 411 to abut against the outer side of the flange through the blocking block 41, and at the same time, the flange is pushed and positioned to the coaxial position of the guide column 42, so that the flange is coaxially aligned with the vertical rod.

[0051] It should be noted that when the flange is square, the abutting square rods 323 and the drawer box 411 are respectively abutted on the four sides of the square flange, so as to position the square flange.

[0052] When the positioning of the flange and the stand with different diameters is needed, the operator manually rotates the positioning screw 334, so that the positioning screw 334 is withdrawn from the positioning hole, and the end face threaded disc 362 and the rotating disc 333 can be freely rotated respectively, so that the operator rotates the end face threaded disc 362 and the rotating disc 333 respectively, so that the flange and the stand are clamped and centered respectively, and then the operator rotates the positioning screw 334 again, so that the end face threaded disc 362 and the rotating disc 333 are locked together, so that the rotating disc 333 can simultaneously align the flange and the stand.

[0053] It should be noted that, as Figure 4 and Figure 6 shown, the cross plate 363 is rotatably arranged on the right side of the shaft sleeve 361, the cross plate 363 is slidably connected with the feeding block 327, and the cross plate 363 is slidably connected with the fixed support 31, so that the cross plate 363 drives the feeding block 327 to be always screw-connected on the end face threaded disc 362, and the cross plate 363 blocks the feeding block 327 from rotating with the end face threaded disc 362.

[0054] Referring to Figure 4 , Figure 5 and Figure 6 , the guide column 42 is provided with a guide groove 421 on the outer side, the left and right two parts of the guide groove 421 are in C-shaped structure, and the middle part of the guide groove 421 is in a spiral structure connecting the two C-shaped structures, and the abutting column 321 is slidably connected on the guide groove 421 through the protruding column thereon.

[0055] It should be noted that, in the initial state, the protruding columns on the abutting column 321 are all located inside the C-shaped structure on the left part of the guide groove 421, so that the abutting column 321 is blocked by the end of the C-shaped structure on the left part of the guide groove 421, preventing the upper part of the disc plate 36 from rotating forward, and the disc plate 36 prevents the threaded rod 331 from rotating with the rotating disc 333 through the shaft sleeve 361, so that the rotating disc 333 is threadedly connected with the threaded rod 331.

[0056] When the flange and the stand are clamped and positioned, the operator manually rotates the one-way screw rod 351, so that the tapered head block 352 pushes the stand to continue moving to the right, the stand drives the flange to move synchronously, the flange pushes the guide column 42 through the abutting column 321, so that the guide column 42 compresses the spiral spring, the guide column 42 drives the pushing plate frame 325 to move synchronously through the linkage plate 324, so that the pushing plate frame 325 pushes the abutting square rod 323 away from the stand through the inclined groove part of the track groove thereon, so that the abutting square rod 323 and the drawer box 411 are no longer in contact with the flange, at this time the spiral spring pushes the flange to always abut on the stand through its elastic force, preventing the position of the flange from changing, and then the stand pushes the guide column 42 to abut on the fixed support 31, so that the stand abuts on the flange.

[0057] It needs to be explained that the left side of the rack 1 is provided with an L-shaped plate which is rotatably connected with the one-way screw 351 through the vertical section of the L-shaped plate, and the upper side of the L-shaped plate is fixedly installed with a driving motor which is rotatably connected with the taper block 352 through a belt, and the welding gun 2 is connected with the rack 1 through a support which can adjust the position.

[0058] When the stand rod abuts against the flange, the welding gun 2 is moved to the contact position of the stand rod and the flange, and the welding gun 2 is started to weld the stand rod and the flange, and the driving motor is started to drive the stand rod and the flange to rotate through the taper block 352, so that the welding gun 2 performs the circular seam welding on the stand rod and the flange.

[0059] Meanwhile, the stand rod and the flange drive the upper part of the disc plate 36 to rotate backward, so that the disc plate 36 drives the abutting column 321 to rotate synchronously, the abutting column 321 moves along the track of the guide groove 421 through the protruding column thereon, so that the abutting column 321 which rotates backward and corresponds to the welding completion position of the stand rod and the flange moves rightward along the track of the guide groove 421, so that the abutting column 321 which does not contact the position corresponding to the welding completion area of the flange any more, thereby reducing the possibility of the welding slag splashing to the flange and the abutting column 321 and causing adhesion.

[0061] During welding, the blocking block 41 blocks above the flange to prevent the welding slag from passing over the flange, when the welding slag splashes to the inside of the blocking block 41, the welding slag contacts the buffer plate 413 or the inclined surface of the reflecting block 414, the buffer plate 413 is elastically connected to the buffer spring, so that the buffer plate 413 slows down the splashing welding slag, and the reflecting block 414 rebounds to guide the welding slag to pop into the inside of the drawer box 411, thereby collecting the welding slag, reducing the situation that the welding slag adheres to the flange or the stand rod, improving the welding quality, and the welding slag can be concentratedly treated by pulling out and cleaning the drawer box 411.

[0062] Referring to Figures 1 to 8 , the present application further comprises the following steps when welding the stand rod and the flange: first, the operator manually sets the flange outside the shaft sleeve 361, and at the same time, the right side of the flange is attached to the left side of the abutting column 321, then the operator sets the right side of the stand rod outside the threaded rod 331, and sets the left side of the stand rod on the taper block 352.

[0063] Second step, the operator manually rotates the rotating disc 333, so that the inner support plate 34 abuts against the inner side of the vertical rod, the rotating disc 333 is matched with the flange through the end face threaded disc 362 abutting against the square rod 323, so that the flange is coaxially aligned with the vertical rod.

[0064] Third step, the operator manually rotates the one-way screw rod 351, so that the conical head block 352 pushes the vertical rod to continue moving to the left, so that the guide column 42 drives the abutting square rod 323 to no longer contact the flange, at the same time, the vertical rod pushes the guide column 42 to abut against the fixed support 31, so that the vertical rod abuts against the flange.

[0065] Fourth step, the welding gun 2 is moved to the position where the vertical rod contacts the flange, the welding gun 2 is started to weld the vertical rod and the flange, at the same time, the driving motor is started to drive the vertical rod and the flange to rotate through the conical head block 352, so that the welding gun 2 performs circular seam welding on the vertical rod and the flange.

[0066] Fifth step, the abutting column 321 corresponding to the vertical rod and the flange welding completion position is moved to the right along the track of the guide groove 421, so that the abutting column 321 does not contact the position where the flange welding is completed, thereby reducing the possibility of welding slag splashing onto the abutting column 321 and the flange to cause adhesion.

[0067] Sixth step, the blocking block 41 blocks above the flange to prevent the welding slag from passing over the flange, at the same time, the buffer plate 413 slows down the splashing welding slag, and the welding slag is guided to pop into the inside of the drawer box 411 through the rebound of the reflecting block 414, so as to collect the welding slag.

[0068] Although the embodiments of the present application have been shown and described above, it should be understood that the above-described embodiments are exemplary and should not be construed as limiting the present application, and those skilled in the art can make changes, modifications, replacements and variations to the above-described embodiments within the scope of the present application, which are still covered by the protection scope of the present application.
