DETAILED DESCRIPTION

[0036] In order to make the technical personnel in the art better understand the technical solutions of the present application, the present application will be further described in detail below in conjunction with the drawings.

[0037] As shown in Figures 1-15 An engineering vehicle cab coaming welding device, comprising a first partition 5 and a second partition 51, further comprising an adjusting sleeve 2 rotatably arranged and a support frame 4 rotatably arranged on the adjusting sleeve 2 and vertically distributed, the C-shaped frame 44 symmetrically fixed and installed on the support frame 4 is located on the vertical plane, the adjusting sleeve 2 is rotated to keep the second partition 51 horizontal, and the welding gun 54 symmetrically movably arranged on both sides of the C-shaped frame 44 is located at the connection between the first partition 5 and the second partition 51.

[0038] When the two C-shaped frames 44 are located on the horizontal plane, the two welding guns 54 are respectively located inside the C-shaped frame 44 and at the connection between the first partition 5 and the second partition 51.

[0039] Specifically, the welding table 1 and the rotary table 12 fixedly installed on the top of the welding table 1 by bolts are included, the adjusting sleeve 2 is arranged on the outer wall of one side of the rotary table 12 in an axial rotating manner, the supporting table 25 is fixedly welded on the outer wall of the adjusting sleeve 2, the supporting frame 4 is arranged on the supporting table 25 in an axial rotating manner, the C-shaped frames 44 are fixedly welded on the outer walls of the opposite sides of the supporting frame 4 in a symmetrical manner, and when the first partition rib 5 is placed in the supporting frame 4, the outer wall used for welding of the first partition rib 5 protrudes from the supporting frame 4, the foot stand 13 is fixedly welded on the welding table 1, the moving supporting frame 52 is arranged on the vertical stand 14 fixedly welded on the foot stand 13 in a symmetrical manner in an sliding manner, the mounting table 53 is fixedly installed on the top of the moving supporting frame 52 by bolts in a symmetrical manner, the welding guns 54 are fixedly installed on the top of the mounting table 53 by bolts respectively, the first electric push rod 55 is fixedly installed on the foot stand 13 by bolts, and the output end of the first electric push rod 55 is fixedly installed on the bottom of the moving supporting frame 52.

[0040] Further, when welding between the first partition rib 5 and the second partition rib 51 is needed, the supporting frame 4 and the C-shaped frames 44 are located above the welding table 1 respectively, at this time, the supporting frame 4 and the C-shaped frames 44 are parallel to the top of the welding table 1 respectively, the supporting frame 4 and the adjusting sleeve 2 are parallel to each other, then the first partition rib 5 is inserted into the placing groove on the supporting frame 4 as shown in Figure 1 , and one end of the first partition rib 5 is positioned by abutting against the inner wall of the placing groove on the supporting frame 4, then the second partition rib 51 is placed between the two C-shaped frames 44, at this time, the second partition rib 51 is perpendicular to the first partition rib 5, and the second partition rib 51 keeps in a vertical state, the two C-shaped frames 44 are distributed vertically relative to the adjusting sleeve 2, then the adjusting sleeve 2 is driven to rotate to switch the second partition rib 51 from the vertical state to the horizontal state, and the supporting frame 4 and the first partition rib 5 in the supporting frame 4 swing during the rotation of the adjusting sleeve 2, when the second partition rib 51 keeps in the horizontal state, the two C-shaped frames 44 are located on the vertical plane and at the top and bottom of the second partition rib 51 along the vertical direction, at this time, the two welding guns 54 are located on the opposite sides of the second partition rib 51 and the connection between the first partition rib 5 and the second partition rib 51 respectively, and the welding ends of the two welding guns 54 are respectively directed to the low position of the gap between the first partition rib 5 and the second partition rib 51, then the moving supporting frame 52 is driven to move upward by the first electric push rod 55 to move the two welding guns 54 along the vertical direction, at this time, the two welding guns 54 move from the low position to the high position of the gap between the first partition rib 5 and the second partition rib 51 as shown in Figure 14 , at this time, the two welding guns 54 weld the gap a between the opposite sides of the first partition rib 5 and the second partition rib 51, and Figure 14The arrow in the figure indicates the direction of the two welding guns 54 moving from the low position to the high position along the joint gap. Then the two welding guns 54 are used to weld simultaneously to improve the welding efficiency, and the symmetrically distributed welding heat and force are more uniform, and then the welding of the welding guns 54 and the first electric push rod 55 are stopped when reaching the high position of the joint gap between the first spacer 5 and the second spacer 51, and the adjustment sleeve 2 is reset by being turned over again, so that the two C-shaped frames 44 are separated from between the two welding guns 54, and the second spacer 51 is switched from the horizontal state to the vertical state again.

[0041] Further, after the adjustment sleeve 2 is reset, the support frame 4 is driven to rotate so that the vertical distribution between the support frame 4 and the adjustment sleeve 2 is achieved, and at the same time, the two C-shaped frames 44 are parallel to the adjustment sleeve 2, and then the adjustment sleeve 2 is driven to rotate again to drive the second spacer 51 to switch from the vertical state to the horizontal state again, and at the same time, the two C-shaped frames 44 are close to the welding guns 54 and are located inside the C-shaped frames 44 and at the joint between the first spacer 5 and the second spacer 51, and then the first electric push rod 55 and the two welding guns 54 are started again to weld the other two opposite non-welded joints between the first spacer 5 and the second spacer 51, at this time, the two welding guns 54 move from the high position to the low position along the non-welded gap, as shown in the figure, at this time, the two welding guns 54 weld the gap b of the two opposite joints between the first spacer 5 and the second spacer 51, and Figure 15 Figure 15 The arrow in the figure indicates the direction of the two welding guns 54 moving from the low position to the high position along the joint gap. And when reaching the low position, the welding of the welding guns 54 and the first electric push rod 55 are stopped, at this time, the welding of the first spacer 5 and the second spacer 51 is completed, and then the adjustment sleeve 2 is reset by being turned over again to facilitate the removal of the first spacer 5 and the second spacer 51 as the surrounding plate structural members.

[0042] Therefore, compared with the welding robot, by fixing the moving direction of the welding guns 54, cooperating with the rotation of the adjustment sleeve 2 and the support frame 4, the joints between the first spacer 5 and the second spacer 51 are sequentially located on the welding path of the welding guns 54, and the swinging of the first spacer 5 and the second spacer 51 and the swinging and positioning of the C-shaped frames 44 and the support frame 4 do not block or affect the movement of the welding guns 54, which can realize the rapid reverse welding of the first spacer 5 and the second spacer 51 without disassembling the tooling structure, thereby speeding up the welding efficiency.

[0043] The adjustment sleeve 2 can be driven by an electric push rod with a gear and rack, or by a motor, or by other ways known to those skilled in the art.

[0044] ​The rotating mode of the supporting frame 4 can be through an electric push rod cooperating with a gear rack, through a motor driving rotation, or through any other mode known to those skilled in the art.

[0045] In the above technical solution, the rotating of the supporting frame 4 and the adjusting sleeve 2 and the supporting of the supporting frame 4 and the C-shaped frame 44 on the first partition rib 5 and the second partition rib 51 can make the connection of the first partition rib 5 and the second partition rib 51 sequentially be on the welding moving path of the welding gun 54, so that the full edge seam welding can be realized, and the reverse welding effect can be realized without disassembling the tooling, thereby improving the welding efficiency and solving the cumbersome of the traditional fixed-point position arc welding and plasma arc welding device which needs to manually release the clamping and adjust the position of the welded part again to realize the full edge seam welding.

[0046] As a further provided embodiment of the present application, a supporting frame 45 for supporting the second partition rib 51 is fixedly installed between the two C-shaped frames 44, and a baffle 6 for shielding the one-side opening of the supporting frame 45 is hingedly arranged on the supporting frame 45.

[0047] Specifically, the supporting frame 45 is fixedly welded between the two C-shaped frames 44, and the supporting frame 45 has a one-side opening and a side opening communicating between the two C-shaped frames 44. When welding between the first partition rib 5 and the second partition rib 51 is needed, the supporting frame 4 and the C-shaped frame 44 are respectively located above the welding table 1 and parallel to the top of the welding table 1, the supporting frame 4 and the adjusting sleeve 2 are parallel to each other, the first partition rib 5 is inserted into the supporting frame 4, and the second partition rib 51 is placed between the two C-shaped frames 44 and on the supporting frame 45. At this time, the second partition rib 51 is kept perpendicular to the first partition rib 5 under the support of the supporting frame 45 and the C-shaped frame 44, and then the baffle 6 is flipped to shield the one-side opening of the supporting frame 45, so that the second partition rib 51 is limited between the supporting frame 45 and the two C-shaped frames 44. In the process of swinging of the supporting frame 45 and the two C-shaped frames 44, the second partition rib 51 is limited to avoid falling off. After welding between the first partition rib 5 and the second partition rib 51 is completed and the adjusting sleeve 2 is rotated back to the original position, the baffle 6 is flipped again to unshield the second partition rib 51. At this time, the second partition rib 51 and the first partition rib 5 can be directly taken out from the one-side opening of the supporting frame 45 and the end opening of the supporting frame 4, thereby eliminating the cumbersome of traditional clamping and disassembly.

[0048] The flipping mode of the baffle 6 can be through an electric push rod, through a motor driving, or through any other mode known to those skilled in the art.

[0049] As another embodiment provided by the present application, the auxiliary sleeve pipe 64 with the arc-shaped slot 65 opened on the outer wall is slidingly arranged on the support frame 45, the auxiliary sleeve pipe 64 is slidingly arranged to make the guide block 63 arranged on the baffle 6 move in the arc-shaped slot 65, and the baffle 6 is flipped.

[0050] Specifically, the top plate 11 is fixedly welded on the top of the welding table 1, the baffle 6 is rotatably arranged on the side boss 46 fixedly welded on the baffle 6 through the hinge shaft 61 fixedly welded thereon, the auxiliary sleeve pipe 64 is sleeved on the hinge shaft 61 and slidingly arranged on the side boss 46, the guide block 63 is fixedly welded on the outer wall of the hinge shaft 61 on the baffle 6, and when the auxiliary sleeve pipe 64 slides into the side boss 46, the guide block 63 slides in the arc-shaped slot 65, the hinge shaft 61 rotates, the main spring 62 fixedly installed between the auxiliary sleeve pipe 64 and the side boss 46 is extruded and deformed to store energy, and the hinge shaft 61 rotates to drive the baffle 6 to flip and open the single-side opening of the support frame 45.

[0051] Therefore, the first spacer 5 is inserted on the support frame 4, the second spacer 51 is placed between the two C-shaped frames 44 and on the support frame 45, the support frame 45 and the second spacer 51 are kept in the vertical state, the auxiliary sleeve pipe 64 is extruded and pressed by the bottom of the top plate 11, the main spring 62 is extruded and deformed to store energy, and the baffle 6 is kept in the state of flipping and opening the single-side opening of the support frame 45, then the adjusting sleeve 2 is rotated to make the second spacer 51 switch from the vertical state to the horizontal state. During the rotation of the adjusting sleeve 2, one end of the auxiliary sleeve pipe 64 relative to the main spring 62 gradually separates from the top plate 11, the main spring 62 releases the stored energy to push the auxiliary sleeve pipe 64 to slide, the guide block 63 slides into the arc-shaped slot 65 again to drive the hinge shaft 61 to rotate. At this time, the baffle 6 flips to block the single-side opening on the support frame 45, so that the second spacer 51 is limited on the support frame 45 and between the two C-shaped frames 44. Therefore, by quickly placing the first spacer 5 and the second spacer 51 on the support frame 4 and the support frame 45, and rotating the adjusting sleeve 2 and removing the extrusion between the auxiliary sleeve pipe 64 and the top plate 11, the automatic clamping and limiting of the second spacer 51 is realized, and after the welding between the first spacer 5 and the second spacer 51 is completed, the support frame 45 and the second spacer 51 are kept in the vertical state again to make the auxiliary sleeve pipe 64 slide again, the baffle 6 flips to open the support frame 45, and the automatic clamping and limiting or releasing of the second spacer 51 during the flipping process is realized to speed up the welding efficiency of the first spacer 5 and the second spacer 51.

[0052] As still another embodiment provided by the present application, the guide groove group composed of the first spiral groove 21, the horizontal groove 22 and the second spiral groove 23 which are sequentially and mutually communicated is opened on the adjusting sleeve 2, the top rod 31 is slidingly arranged in the adjusting sleeve 2 along the axial direction, and the guide rod 34 fixedly installed on the top rod 31 is movably arranged in the guide groove group.

[0053] Specifically, the top of the welding table 1 is fixed with a main electric push rod 3 installed by bolts, and one end of the top rod 31 is fixedly installed on the output end of the main electric push rod 3. When the guide rod 34 is located in the horizontal slot 22 in the guide groove group, the support frame 45 and the second partition rib 51 are kept in the vertical state at this time, and the supporting frame 4 and the C-shaped frame 44 are respectively located above the welding table 1 and are respectively parallel to the top of the welding table 1, and the supporting frame 4 and the adjusting sleeve 2 are parallel to each other, and the C-shaped frame 44 is perpendicular to the adjusting sleeve 2.

[0054] When the main electric push rod 3 is started to pull the top rod 31, the guide rod 34 slides along the horizontal slot 22 into the first spiral slot 21 at this time, so as to achieve the purpose of rotating the adjusting sleeve 2, that is, to make the second partition rib 51 switch from the vertical state to the horizontal state. Since the two C-shaped frames 44 are located on the vertical plane, when the second partition rib 51 is in the horizontal state, the guide rod 34 is located at one end of the first spiral slot 21 relative to the horizontal slot 22 at this time, and the two welding guns 54 are respectively located on the opposite sides of the second partition rib 51 and at the connection between the first partition rib 5 and the second partition rib 51. In this state, the welding gun 54 is moved upward to weld the gap a as shown, and after welding is completed, the main electric push rod 3 is started to push the top rod 31, so as to make the guide rod 34 slide along the first spiral slot 21 into the horizontal slot 22 and move into the horizontal slot 22, at this time the support frame 45 and the second partition rib 51 keep the vertical state again, and then the supporting frame 4 is driven to rotate, so that the supporting frame 4 and the adjusting sleeve 2 are vertically distributed, and the two C-shaped frames 44 are parallel to the adjusting sleeve 2. Subsequently, the main electric push rod 3 continues to push the top rod 31, so as to make the top rod 31 slide along the horizontal slot 22 into the second spiral slot 23, at this time the adjusting sleeve 2 rotates again, and the second partition rib 51 switches from the vertical state to the horizontal state again, and then the two C-shaped frames 44 are close to the welding gun 54 and make the two welding guns 54 respectively located inside the C-shaped frame 44 and at the connection between the first partition rib 5 and the second partition rib 51. Figure 14 Subsequently, the welding gun 54 is moved downward again, so as to weld the other two opposite non-welded connection portions between the first partition rib 5 and the second partition rib 51, that is, the gap b as shown, and after the welding of the first partition rib 5 and the second partition rib 51 is completed, the main electric push rod 3 is started again to pull the top rod 31, and then the guide rod 34 slides along the second spiral slot 23 into the horizontal slot 22, and the adjusting sleeve 2 rotates to make the support frame 45 and the second partition rib 51 keep the vertical state again. Therefore, by using the pulling of the main electric push rod 3 and the limiting of the guide groove group, the precise angle limiting of the adjusting sleeve 2 is realized, and the adjusting sleeve 2 can be supported under force to improve the stability of subsequent welding.

[0055] Figure 15 Subsequently, the welding gun 54 is moved downward again, so as to weld the other two opposite non-welded connection portions between the first partition rib 5 and the second partition rib 51, that is, the gap b as shown, and after the welding of the first partition rib 5 and the second partition rib 51 is completed, the main electric push rod 3 is started again to pull the top rod 31, and then the guide rod 34 slides along the second spiral slot 23 into the horizontal slot 22, and the adjusting sleeve 2 rotates to make the support frame 45 and the second partition rib 51 keep the vertical state again. Therefore, by using the pulling of the main electric push rod 3 and the limiting of the guide groove group, the precise angle limiting of the adjusting sleeve 2 is realized, and the adjusting sleeve 2 can be supported under force to improve the stability of subsequent welding.

[0056] ​As another embodiment provided by the present application, the driving rod 38 is slidingly arranged, and the main shaft rod 41 is fixedly arranged on the support frame 4, the first end of the driving rod 38 is movably arranged on the push plate 43 fixedly arranged on the outer wall of the main shaft rod 41, and the torsion spring member 42 is sleeved on the main shaft rod 41 to accumulate force when the driving rod 38 is pushed.

[0057] Specifically, the sliding groove 26 is arranged on the support table 25, and the movable cavity 27 is arranged on the support table 25 and communicated with the sliding groove 26, the push plate 43 is fixedly welded on the outer wall of the main shaft rod 41 and swings in the movable cavity 27, the driving rod 38 is slidingly arranged in the sliding groove 26 and the movable cavity 27, and the torsion spring member 42 is sleeved on the main shaft rod 41 and fixedly arranged on the inner wall of the movable cavity 27 at both ends. In the default state, the torsion spring member 42 drives the push plate 43 to adhere to the inner wall of the movable cavity 27, at this time, the support frame 4 and the adjusting sleeve 2 remain parallel, and then when it is needed to adjust the rotation of the support frame 4 to keep perpendicular with the adjusting sleeve 2, the driving rod 38 is slidingly arranged in the sliding groove 26 and the movable cavity 27 to push the end of the driving rod 38 to push the push plate 43, and then the main shaft rod 41 is rotated under the pushing of the driving rod 38, and in the default state, the driving rod 38 and the push plate 43 are perpendicular to each other, and the bottom extension line of the driving rod 38 and the outer wall of the main shaft rod 41 remain tangent, as shown in FIG. 4, the push plate 43 swings under the pushing of the driving rod 38, and then the push plate 43 adheres to the bottom of the driving rod 38 and remains parallel with the driving rod 38, at this time, the main shaft rod 41 completes a ninety-degree overturning, and the torsion spring member 42 deforms to accumulate force, and the support frame 4 and the adjusting sleeve 2 remain perpendicular. The precise positioning and overturning of the support frame 4 can be realized by the sliding pushing of the driving rod 38 to the push plate 43, and the perpendicular state of the support frame 4 and the adjusting sleeve 2 can be maintained by the shielding of the driving rod 38 and the deformation and force accumulation of the torsion spring member 42, so as to realize precise positioning.

[0058] The sliding mode of the driving rod 38 can be pushing by an electric push rod, or can be gear and rack cooperating with a motor, or can be a mode known to those skilled in the art.

[0059] As the optimal embodiment provided by the present application, the driving rod 38 is arranged on the jacking rod 31.

[0060] ​Specifically, the drive rod 38 is fixedly installed on the top rod 31 and is in a horizontal position via the second partition 51, allowing the two welding guns 54 to weld two of the connection points of the first partition 5 and the second partition 51. The first partition 5 and the second partition 51 are square tubes. After welding, the main electric push rod 3 is activated to push the top rod 31, thereby causing the guide rod 34 to slide along the first spiral groove 21 into the horizontal groove 22 and move into the horizontal groove 22. At this time, the end of the drive rod 38 still maintains a distance from the lever plate 43. Then, the guide rod 34 enters the water... When the guide rod 34 is sliding along the horizontal groove 22, the support frame 45 and the second partition 51 remain vertical. Then, the main electric push rod 3 continues to push the push rod 31 to make the guide rod 34 slide along the horizontal groove 22. At this time, the end of the drive rod 38 begins to push the dial plate 43, and then the main shaft 41 rotates under the push of the drive rod 38. Then the dial plate 43 flips and fits against the bottom of the drive rod 38 and remains parallel to the drive rod 38. At this time, the main shaft 41 completes a 90-degree flip, and the torsion spring 42 deforms and stores force. The support frame 4 and the adjusting sleeve 2 remain vertical. Then, the main electric push rod 3 continues to push the push rod 31 so that the guide rod 34 slides along the horizontal groove 22 into the second spiral groove 23. At this time, the adjusting sleeve 2 rotates again, and the second partition 51 switches from the vertical state to the horizontal state again. Then, the two C-shaped frames 44 move closer to the welding gun 54 and the two welding guns 54 are respectively located inside the C-shaped frame 44 and at the connection between the first partition 5 and the second partition 51. Then, the welding gun 54 is moved down again to weld the other two relatively unwelded connection points of the first partition 5 and the second partition 51.

[0061] Therefore, by using the main electric push rod 3 to drive the push rod 31 to slide, the rotation of the adjusting sleeve 2 is driven, and the drive rod 38 can cooperate with the push plate 43 to drive the support frame 4 to flip, thereby achieving precise positioning and switching control between kinetic energy.

[0062] In another embodiment of the present invention, the drive rod 38 is fixedly installed on the collar 35 that is slidably disposed on the outer wall of the adjusting sleeve 2, and the top sleeve 32 and the collar 35 that are fixedly installed on the outer wall of the top rod 31 are movably assembled.

[0063] Specifically, the outer wall of the adjusting sleeve 2 near one end of the main electric push rod 3 is fixedly installed with an integral side part 24, the sleeve ring 35 is fixedly welded with an extension plate 37, and the driving rod 38 is fixedly welded on the extension plate 37. The top sleeve 32 is fixedly welded on the outer wall of the top rod 31, the end of the top sleeve 32 is fixedly installed with the first magnet ring 33 through glue, and the outer wall of the side of the sleeve ring 35 is fixedly installed with the second magnet ring 36 through glue, and the default state is that the sleeve ring 35 is located on one side of the side part 24. At this time, one end of the driving rod 38 is attached to the push plate 43, and when the guide rod 34 slides along the first spiral groove 21, the first magnet ring 33 and the second magnet ring 36 maintain a distance, and the driving rod 38 does not move with the top rod 31. When the guide rod 34 gradually slides along the horizontal groove 22 to approach the second spiral groove 23, the first magnet ring 33 gradually adheres to the second magnet ring 36, and then the guide rod 34 slides in the horizontal groove 22, so that the top rod 31 drives the driving rod 38 to slide and push the push plate 43 to overturn, thereby driving the support frame 4 to overturn, and the top sleeve 32 slides on the outer wall of the adjusting sleeve 2. When the guide rod 34 slides in the horizontal groove 22 to approach the first spiral groove 21, the first magnet ring 33 and the second magnet ring 36 are separated again under the shielding of the side part 24 to the sleeve ring 35, and the driving rod 38 is removed from the push plate 43.

[0064] By the movable connection and magnetic attraction of the top sleeve 32 and the sleeve ring 35, the length of the driving rod 38 can be reduced, and one end of the driving rod 38 is located on one side of the push plate 43 in the default state, thereby avoiding the need to consider the guide insertion of the driving rod 38 in the sliding groove 26 when the driving rod 38 is fixedly installed on the top rod 31. The overlong driving rod 38 also reduces its stability and supportability, effectively improves the structural strength, and avoids the problem that the overlong driving rod 38 is easily bent and deformed under stress, affecting the push-over precision.

[0065] As another embodiment of the application, the hollow part 7 is arranged in the side table 47 fixedly installed on the support frame 45, and the short rod 74 with the first end movably arranged on the outer wall of the second partition 51 is arranged in the hollow part 7.

[0066] Specifically, the hollow piece 7 is fixedly welded on the side table 47, the side table 47 is fixedly welded on the support frame 45, and the support table 15 is fixedly installed on the foot stand 13 by bolts. When the guide rod 34 is pulled by the main electric push rod 3 to slide into the first spiral groove 21 along the horizontal groove 22, the second partition rib 51 is switched from the vertical state to the horizontal state at this time. In the process of the second partition rib 51 overturning with the support frame 45, the short rod 74 gradually approaches the support table 15, and then when the second partition rib 51 is in the horizontal state, the support table 15 supports the short rod 74 to push the outer wall of the second partition rib 51, so that the second partition rib 51 is closely attached to the support frame 45 to keep stable, avoiding the problems of deviation caused by subsequent welding or equipment vibration.

[0067] As further provided in another embodiment of the application, the hollow piece 7 is slidingly arranged in the side table 47, and the hollow piece 7 slides away from the first partition rib 5 when the short rod 74 pushes on the second partition rib 51.

[0068] Specifically, the bottom end of the hollow piece 7 is slidingly provided with a long rod 71, a compression spring 73 is fixedly installed between the long rod 71 and the short rod 74, a non-slip rubber pad 75 is fixedly installed on one end of the outer wall of the second partition rib 51 through glue, and a plurality of auxiliary shafts 48 are rotatably arranged on the support frame 45.

[0069] Further, when the guide rod 34 is pulled by the main electric push rod 3 to slide into the first spiral groove 21 along the horizontal groove 22, the second partition rib 51 is switched from the vertical state to the horizontal state at this time, and in the process of the second partition rib 51 overturning with the support frame 45, the auxiliary roller 72 axially arranged at the bottom end of the long rod 71 gradually approaches and adheres to the support table 15, and as the support frame 45 continues to overturn, the long rod 71 slides in the hollow piece 7 and extrudes the compression spring 73 to deform and store force, and then the compression spring 73 pushes the short rod 74 to make the anti-skid rubber pad 75 adhere to the outer wall of the second partition rib 51, and the second partition rib 51 adheres to the plurality of auxiliary shaft rods 48, and then slides away from the first partition rib 5 through the hollow piece 7, so as to utilize the friction between the anti-skid rubber pad 75 and the second partition rib 51 to drive the second partition rib 51 to slide in the support frame 45, and make the end of the second partition rib 51 away from the outer wall of the first partition rib 5, so that the welding gap between the outer wall of the first partition rib 5 and the end of the second partition rib 51 is generated, and thus in this way, when the second partition rib 51 is in the vertical state, the gravity of the second partition rib 51 makes the end of the second partition rib 51 closely adhere to the first partition rib 5, and then in the process of the second partition rib 51 overturning, the second partition rib 51 always keeps pressing the first partition rib 5 to improve the stability of the first partition rib 5, and then when the second partition rib 51 is switched from the vertical state to the horizontal state, the anti-skid rubber pad 75 on the short rod 74 presses the second partition rib 51, and then cooperates with the sliding of the hollow piece 7 to drive the second partition rib 51 to move and generate the welding gap with the outer wall of the first partition rib 5, thereby solving the step of manually adjusting the welding gap and improving the production efficiency.

[0070] The sliding mode of the hollow piece 7 can be pushing by the electric push rod, or can be gear and rack cooperating with the motor, or can be the mode known to those skilled in the art for driving the hollow piece 7 to slide.

[0071] As a further provided optimal embodiment of the application, the second magnetic plate 17 is arranged, and the first magnetic plate 77 arranged on the hollow piece 7 is movably assembled with the second magnetic plate 17.

[0072] Specifically, the top of the support table 15 is fixedly welded with the alignment rack 16, the second magnetic plate 17 is fixedly bonded on the outer wall of one side of the alignment rack 16 by glue, the hollow piece 7 is fixedly welded with the extension frame 76, and the first magnetic plate 77 is fixedly bonded on the extension frame 76 by glue. The limit spring 78 is fixedly installed between the hollow piece 7 and the side table 47.

[0073] Furthermore, when the guide rod 34 is pulled by the main electric push rod 3 to slide along the horizontal groove 22 into the first spiral groove 21, the second partition 51 switches from a vertical state to a horizontal state. As the second partition 51 rotates along with the support frame 45, the auxiliary roller 72 gradually approaches and adheres to the support platform 15, and the compression spring 73 is squeezed and deformed by the long rod 71 to store force. Then, the compression spring 73 pushes the short rod 74 to make the anti-slip rubber pad 75 adhere to the outer wall of the second partition 51, and the second partition 51 adheres to multiple auxiliary shafts 48. Subsequently, as the support frame 45 continues to rotate, the first magnetic plate 77 and the second magnetic plate 17 move closer together. Simultaneously, the compression spring 73, in a deformed and charged state, keeps the support frame 45 in a stable clamped position. At the same time, the magnetic attraction between the first magnetic plate 77 and the second magnetic plate 17 causes the first magnetic plate 77 to slide the hollow component 7 closer to the second magnetic plate 17. As the hollow component 7 slides away from the first rib 5, the friction between the anti-slip rubber pad 75 and the second rib 51 causes the second rib 51 to slide within the support frame 45 and away from the outer wall of the first rib 5, thus creating a welding gap between the outer wall of the first rib 5 and the ends of the second rib 51. When the second rib 51 switches to a horizontal state, the support frame 45 is then attached to the top of the alignment platform 16 and is supported and stabilized by the alignment platform 16. By magnetically attracting the first magnetic plate 77 and the second magnetic plate 17, the friction between the anti-slip rubber pad 75 and the second rib 51 can be effectively increased during the rotation of the support frame 45. Subsequently, the hollow part 7 is magnetically attracted and slids, causing the second rib 51 to move away from the reserved welding gap of the first rib 5. When the second rib 51 is moved by the hollow part 7, it is pushed against the inner wall of the single-sided opening on the support frame 45, thereby fixing the reserved welding gap distance between the second rib 51 and the first rib 5, avoiding the tediousness of manual adjustment. After the welding gap is welded, if the weld leg shrinks due to cooling, causing the second rib 51 to move slightly towards the first rib 5, the magnetic attraction between the first magnetic plate 77 and the second magnetic plate 17 can cause the second rib 51 to shrink and shift by a certain distance, thereby offsetting part of the stress caused by the shrinkage of the weld leg and reducing the problem of slight deformation of the first rib 5 caused by welding shrinkage stress. Compared to traditional fixed installation fixtures, when multiple structural components are simultaneously clamped and welded, the shrinkage stress generated by the cooling of multiple weld legs will accumulate. This stress, when acting on the enclosure or similar components like the second rib 51 and the first rib 5, will cause slight deformation of the second rib 51 or the first rib 5 itself. When this deformation acts on the engineering vehicle, especially on the enclosure at the door frame, it can lead to problems such as poor sealing at the door frame or friction when opening and closing the door. Relieving this stress can effectively improve production quality.

[0074] Working principle: keep the support frame 45 in vertical state, and the guide rod 34 is located in the horizontal slot 22 in the guide slot group, in this state, the auxiliary sleeve 64 is blocked and extruded by the bottom of the top plate 11, and then the main spring 62 is extruded and deformed to store force, and the baffle 6 keeps the one-sided opening state of the support frame 45, and the first partition 5 is inserted on the support frame 4, and the second partition 51 is placed between the two C-shaped frames 44 and the support frame 45, at this time, the support frame 4 and the C-shaped frame 44 are located above the welding table 1 and are parallel to the top of the welding table 1 respectively, the support frame 4 and the adjusting sleeve 2 are parallel to each other, and the C-shaped frame 44 is perpendicular to the adjusting sleeve 2. By starting the main electric push rod 3 to pull the top rod 31, and then the guide rod 34 slides along the horizontal slot 22 into the first spiral slot 21, at this time, the adjusting sleeve 2 rotates, and the second partition 51 switches from the vertical state to the horizontal state, and the two C-shaped frames 44 are located on the vertical plane, as shown in Figure 2 When the second partition 51 is in the horizontal state, the guide rod 34 is located at one end of the first spiral slot 21 opposite the horizontal slot 22, and the two welding guns 54 are located on the opposite sides of the second partition 51 and at the connection between the first partition 5 and the second partition 51. During the process of the second partition 51 being flipped with the support frame 45, the auxiliary roller 72 gradually approaches and adheres to the support table 15, and the compression spring 73 is extruded and deformed by the long rod 71 to store force, and then the compression spring 73 pushes the short rod 74 to make the anti-skid rubber pad 75 adhere to the outer wall of the second partition 51, and the second partition 51 adheres to the plurality of auxiliary shafts 48. Then, during the continuous flipping of the support frame 45, the first magnetic plate 77 and the second magnetic plate 17 approach each other, and the support frame 45 is kept in a clamped stable state under the condition of the compression spring 73 being deformed to store force, and the first magnetic plate 77 and the second magnetic plate 17 are magnetically attracted to each other, so that the first magnetic plate 77 drives the hollow part 7 to slide and approach the second magnetic plate 17, and in the process of the hollow part 7 sliding away from the first partition 5, the second partition 51 is driven to slide in the support frame 45 and away from the outer wall of the first partition 5 by using the friction between the anti-skid rubber pad 75 and the second partition 51, so that the outer wall of the first partition 5 and the end of the second partition 51 have a welding gap.

[0075] Furthermore, in this state, welding is performed by pushing the welding gun 54 upwards using the first electric push rod 55. After welding is completed, the main electric push rod 3 is activated to push the push rod 31, thereby causing the guide rod 34 to slide along the first spiral groove 21 into the horizontal groove 22 and move into the horizontal groove 22. At this time, the support frame 45 and the second partition 51 remain vertical again. Then, the main electric push rod 3 continues to push the guide rod 34, and the guide rod 34 gradually slides along the horizontal groove 22 closer to the second spiral groove 23. At this time, the first magnetic ring 33 gradually adheres to the second magnetic ring 36. Subsequently, as the guide rod 34 slides in the horizontal groove 22, the push rod 31... The drive rod 38 slides and pushes the push plate 43 to rotate, thereby causing the support frame 4 to rotate 90 degrees. At this time, the support frame 4 and the adjusting sleeve 2 are vertically distributed, and the two C-shaped frames 44 are parallel to the adjusting sleeve 2. Then, the main electric push rod 3 continues to push the push rod 31, so that the push rod 31 slides along the horizontal groove 22 into the second spiral groove 23. At this time, the adjusting sleeve 2 rotates again, and the second partition 51 switches from a vertical state to a horizontal state again. Then, the two C-shaped frames 44 move closer to the welding gun 54 and the two welding guns 54 are respectively located inside the C-shaped frame 44 and at the connection between the first partition 5 and the second partition 51. Figure 3 As shown, when the second rib 51 is in a horizontal state, both C-shaped frames 44 are simultaneously on the same horizontal plane as the second rib 51. Then, the welding gun 54 is moved down again to weld the other two unwelded joints of the first rib 5 and the second rib 51. After welding the first rib 5 and the second rib 51, the main electric push rod 3 is activated again to pull the top rod 31. Then, the guide rod 34 slides along the second spiral groove 23 into the horizontal groove 22. The adjusting sleeve 2 rotates to keep the support frame 45 and the second rib 51 vertical again. Therefore, by utilizing the pulling of the main electric push rod 3 and the limiting of the guide groove group, the precise angle of the adjusting sleeve 2 is limited, and the adjusting sleeve 2 can be supported to improve the stability of subsequent welding. Automatic clamping and limiting or releasing of the second rib 51 during the flipping process is also achieved to accelerate the welding efficiency of the first rib 5 and the second rib 51.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
