The surface of the positioning frame 3 is clamped and fixed with a connecting plate 4. The two long side surfaces of the connecting plate 4 are provided with limiting grooves 5. The surface of the connecting plate 4 is fixedly connected with a transparent net 6. When the welding head angle of the welding device is not well aligned, the user can operate the machine table 2 so that the positioning frame 3 on the output end drives the connecting plate 4 to flip. During this process, the special-shaped steel and the steel parts waiting to be welded thereto will be flipped to a suitable angle to facilitate the welding device to connect to the welding operation. During the operation, the generated welding slag will directly fall through the transparent net 6 to prevent it from bouncing and covering the surface of the special-shaped steel due to movements such as bouncing, and solidify and connect with it before cooling;

The limiting slot 5 is first clamped by the screw bolt 11 and the conical head 10 in conjunction with the bolt 9. Then, according to the actual contact position of the conduit 19 fitting with the special-shaped steel, the user can control the operation of the first motor 13 and the second motor 17 respectively. After the two-axis angle adjustment, the surface of the conduit 19 is finally facing the surface of the special-shaped steel, and then wait for its positioning to be completed;

[0036] The surface of one end of the conduit 19 is fixedly connected to the air valve 20, and the side surface of the conduit 19 is provided with a friction pattern 21 at one end edge.

After the supporting plate 16 supports the special-shaped steel, the user can rotate the screw sleeve 23 to make it stay in the appropriate position on the surface of the friction pattern 21. In this process, as the latex sleeve 26 is pushed outward, the rubber pads 27 on both sides will slowly expand outward until they are attached to the surface of the special-shaped steel. At this time, the external exhaust equipment is controlled to generate negative pressure in the latex sleeve 26, further improving the connection stability to ensure that the special-shaped steel remains stable during positioning welding.

The inner sides of the two pads 32 are rotatably connected to the lower pad roller 33 at the middle part, and the inner sides of the two pads 32 are rotatably connected to the upper pad roller 34 at the upper end.

[0038] The number of the arc-shaped plates 40 is set to two. The inner sides of the two arc-shaped plates 40 are fixedly connected to a gear rack 41 at the bottom end. The gear rack 41 is meshed with the toothed rod 39. A third motor 42 is fixedly installed on the inner sides of the two arc-shaped plates 40 near the upper end. The output end of the third motor 42 is fixedly connected to a positioning plate 43. The surface of the positioning plate 43 is fixedly connected to a straight shaft 44.

The output end of the pusher 46 is fixedly connected to a fixing frame 47. After the user places the steel parts to be welded on the surface of the gasket 45, The user can start the pusher 46 so that the eccentric block 47 gradually supports it in a limited position, and then control the third motor 42 to operate, which can drive the positioning plate 43 and the straight shaft 44 to rotate a certain angle, first adjust its flip angle relative to the connecting plate 4, and then control the cylinder 36 to operate so that its output end drives the soft head 37 to extend and retract, and in the linkage sleeve 38, it will eventually cause the toothed rod 39 to rotate, and the tooth rack 41 frictionally connected to it will rotate between the lower pad roller 33 and the upper pad roller 34 in this process, thereby completing the rotation of the steel part in the direction of the central axis of the connecting plate 4 to meet the welding angle adaptation requirements with the special-shaped steel.

[0039] A fourth motor 48 is fixedly installed on the surface of the fixed frame 47 at the middle part, and a conveyor belt 49 is sleeved on the output end of the fourth motor 48. A driven wheel 50 is connected to the inner side of the conveyor belt 49, and a transmission belt is sleeved on the surface of the driven wheel 50. A transmission belt is sleeved on the inner side of the transmission belt, and a transmission wheel 51 is connected to the inner side of the transmission belt. A support frame 52 is fixedly connected to the surface of the fixed frame 47 near the two side edges, and an inner support wheel 53 is rotatably connected to the surface of the support frame 52. The transmission wheel 51 and the inner support wheel 53 are fixedly connected, and a cushion belt 54 is sleeved on the surface of the inner support wheel 53. A roller is rotatably connected to the surface of one end of the fixed frame 47 near the top, and the roller is sleeved on the cushion belt 54. A special-shaped frame 55 is sleeved on the surface of the support frame 52, and a connecting block 56 is fixedly connected to the surface of the special-shaped frame 55 near the middle. 5 is rotatably connected to an auxiliary pad wheel 57 near the lower end, and a shock absorber 58 is fixedly connected to the surface of the special-shaped frame 55 near the upper end. After the pusher 46 completes pushing, the pad belt 54 will be attached to the surface of the steel part, and cooperate with the gasket 45 to support the steel part from three sides. After the fourth motor 48 drives the conveyor belt 49 to rotate, the driven wheel 50 and the transmission wheel 51 are linked, and finally the inner support wheel 53 is rotated, thereby driving the pad belt 54 to rotate. On the one hand, it can drive the steel part to move forward stably during the early feeding, avoiding the errors that may be caused by manual adjustment. On the other hand, during the welding process of steel parts and special-shaped steel, the deformation compensation caused by thermal expansion can be satisfied through adaptive rotation, and the influence of deformation vibration can be further reduced by cooperating with the auxiliary pad wheel 57.

[0040] The working principle of the present invention is: when the welding head angle of the welding device is not well aligned, the user can operate the machine 2 so that the positioning frame 3 on the output end drives the connecting plate 4 to flip. During this process, the special-shaped steel and the steel parts waiting to be welded therewith will flip to a suitable angle to facilitate the welding device to connect to the welding operation. During the operation, the welding slag generated will fall directly through the transparent mesh 6 to prevent it from bouncing and covering the surface of the special-shaped steel due to actions such as bouncing, and solidify and connect with it before cooling. For the positioning of the special-shaped steel, first use four groups of shift plates 7 to roughly limit the special-shaped steel from the four corners, first use the screw bolt 11 and the conical head 10 to cooperate with the bolt 9 to clamp the limiting groove 5, and then According to the actual contact position of the conduit 19 fittings with the special-shaped steel, the user can control the operation of the first motor 13 and the second motor 17 respectively. After the two-axis angle adjustment, the surface of the conduit 19 is finally facing the surface of the special-shaped steel, and then wait for it to be positioned. After the supporting plate 16 supports the special-shaped steel, the user can rotate the screw sleeve 23 to make it stay in the appropriate position on the surface of the friction pattern 21. During this process, as the latex sleeve 26 moves outward, the rubber pads 27 on both sides will slowly expand outward until they are attached to the surface of the special-shaped steel. At this time, the external exhaust equipment is controlled to generate negative pressure in the latex sleeve 26, further improving the connection stability to ensure that the special-shaped steel is in a stable state. The positioning welding process remains stable. After the user places the steel part to be welded on the surface of the gasket 45, the user can start the pusher 46 to make the eccentric block 47 gradually limit and support it, and then control the third motor 42 to operate, which can drive the positioning plate 43 and the straight shaft 44 to rotate a certain angle, first adjust its flip angle relative to the connecting plate 4, and then control the cylinder 36 to operate so that its output end drives the soft head 37 to extend and retract, and in the linkage sleeve 38, it will eventually make the toothed rod 39 rotate, and the tooth rack 41 frictionally connected to it will rotate between the lower pad roller 33 and the upper pad roller 34 in this process, thereby completing the rotation of the steel part in the direction of the central axis of the connecting plate 4 to meet its In order to adapt to the welding angle requirements of the special-shaped steel, after the pusher 46 has completed pushing, the pad belt 54 will be attached to the surface of the steel part, and cooperate with the gasket 45 to support the steel part from three sides, and after the fourth motor 48 is used to drive the conveyor belt 49 to rotate, the driven wheel 50 and the transmission wheel 51 are linked, and finally the inner support wheel 53 will rotate, thereby driving the pad belt 54 to rotate. On the one hand, it can drive the steel part to move forward stably during the early feeding, avoiding the errors that may be caused by manual adjustment. On the other hand, during the welding process of steel parts and special-shaped steel, the deformation compensation caused by thermal expansion can be met through adaptive rotation, and the auxiliary pad wheel 57 can be used to further reduce the impact of deformation vibration.

[0041] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
