Description

Technical Field

[0001] This utility model relates to the field of civil defense door production technology, and in particular to a multi-station double-shield welding device. Background Technology

[0002] Civil defense doors are the entrances and exits of civil defense projects. They are clearly categorized, including ordinary single and double-leaf protective airtight doors and airtight doors, as well as single and double-leaf protective airtight doors and airtight doors with movable thresholds, among other types of civil defense equipment. During the production and processing of civil defense doors, the door frame and door panel need to be welded together. Currently, the welding is mainly done step-by-step on one side, resulting in low welding efficiency and affecting the processing schedule. Utility Model Content

[0003] The purpose of this invention is to provide a multi-station MIG welding device to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A multi-station MIG / MAG welding device includes a frame, a support mechanism for moving and supporting a door frame, a pushing mechanism for pushing the door frame, and an adjustment mechanism for adjusting the position of the welding torch used to weld the door panel to the door frame. The support mechanism includes left and right helical screws and guide columns mounted on the frame, with the guide columns positioned on the front and rear sides of the helical screws respectively. One end of each helical screw is connected to a variable-speed motor, and support plates are mounted opposite each other on the helical screws and guide columns. Support rollers are installed at intervals on opposite surfaces of the support plate; the pushing mechanism includes a reciprocating screw mounted on the support plate, a sliding seat mounted on the reciprocating screw, a servo motor connected to one end of the reciprocating screw, and a push plate rotatably connected to the lower end of the sliding seat; the adjusting mechanism is provided in two opposite locations on the support plate, the adjusting mechanism includes a vertical frame mounted on the upper part of the support plate, a vertical screw mounted on the vertical frame, a crossbeam mounted on the vertical screw, a horizontal groove opened on the crossbeam, a transverse screw mounted on the crossbeam passing through the horizontal groove, and a mounting seat mounted on the transverse screw within the horizontal groove.

[0006] Further configuration: The support rollers on both sides are set at the same height, the support rollers are rotatably connected to the support plate, and the support plate has a groove on the upper side of the support roller, with guide rollers installed at intervals in the groove.

[0007] Further configuration: The outer tangent of the guide roller protrudes from the inner side of the support plate, and the guide roller is rotatably connected to the support plate.

[0008] Further configuration: The left and right helical screws are rotatably connected to the frame, the left and right helical screws are threadedly connected to the support plate, and the support plate is slidably connected to the guide column.

[0009] Further configuration: The two sides of the push mechanism are arranged opposite each other, the reciprocating screw is rotatably connected to the support plate, the sliding seat is threadedly connected to the reciprocating screw, and the push plate rotates to the side opposite to the support plate.

[0010] Further configuration: The vertical screw is rotatably connected to the upright frame, the vertical screw is threadedly connected to the crossbeam, the crossbeam slides on the upright frame, the horizontal screw is rotatably connected to the crossbeam, and the horizontal screw is threadedly connected to the mounting base.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] By setting up a support mechanism, a pushing mechanism, and an adjusting mechanism, the left and right helical screws rotate, pushing the support plates to move relative to each other under the support of the guide columns. This ensures that the spacing between the support plates meets the placement requirements of the door frame width. The support rollers support the door frame and door panel. Rotating the vertical screw adjusts the height of the crossbeam, and rotating the horizontal screw aligns the welding gun on the mounting base with the weld seams of the door frame and door panel. This causes the reciprocating screw to rotate, pushing the sliding seat and push plate to move the door frame backward, allowing the welding gun to simultaneously weld the weld seams on both sides of the door frame, thus improving the welding efficiency between the door frame and door panel.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-6 As shown, a multi-station MIG welding device includes a frame 1, a support mechanism for moving and supporting a door frame, a pushing mechanism for pushing the door frame, and an adjustment mechanism for adjusting the position of the welding torch 5 for welding the weld between the door panel and the door frame, which is provided on the support mechanism.

[0026] In this embodiment: the support mechanism includes left and right helical screws 21 and guide columns 22 mounted on the frame 1. The guide columns 22 are respectively mounted on the front and rear sides of the left and right helical screws 21. One end of the left and right helical screws 21 is connected to a variable speed motor 24. Support plates 23 are arranged opposite to each other on the left and right helical screws 21 and guide columns 22. Support rollers 25 are installed at intervals on the opposite surfaces of the support plates 23. The two support rollers 25 are set at the same height and are rotatably connected to the support plates 23. A groove is opened on the support plate 23 on the upper side of the support rollers 25, and guide rollers 26 are installed at intervals in the groove. The outer surface of the 6-section protrudes from the inner side of the support plate 23. The guide roller 26 is rotatably connected to the support plate 23. The left and right helical screws 21 are rotatably connected to the frame 1. The left and right helical screws 21 are threadedly connected to the support plate 23. The support plate 23 is slidably connected to the guide column 22. The left and right helical screws 21 are driven to rotate by the operation of the variable speed motor 24. The left and right helical screws 21 push the support plate 23 to move relative to each other under the support of the guide column 22, so that the spacing between the support plates 23 meets the placement requirements of the door frame width. The support roller 25 provides moving support for the door frame, and the guide roller 26 provides moving guidance for the door frame.

[0027] In this embodiment: the pushing mechanism is arranged opposite to each other on both sides. The pushing mechanism includes a reciprocating screw 31 arranged on the support plate 23. A sliding seat 33 is arranged on the reciprocating screw 31. A servo motor 32 is connected to one end of the reciprocating screw 31. A push plate 34 is rotatably connected to the lower end of the sliding seat 33. The reciprocating screw 31 is rotatably connected to the support plate 23. The sliding seat 33 is threadedly connected to the reciprocating screw 31. The push plate 34 rotates to the opposite side of the support plate 23. The servo motors 32 on both sides are of the same specification and model. The servo motor 32 drives the reciprocating screw 31 to rotate, so that the reciprocating screw 31 pushes the sliding seat 33 and the push plate 34 to push the door frame to move backward under the limit of the support roller 25 and the guide roller 26. The welding gun 5 welds the welds on both sides of the door frame simultaneously.

[0028] In this embodiment: the adjustment mechanism is provided in two locations on the support plate 23. The adjustment mechanism includes a vertical frame 41 set on the upper end of the support plate 23. A vertical screw 42 is vertically set on the vertical frame 41. A crossbeam 43 is installed on the vertical screw 42. A horizontal groove is opened on the crossbeam 43. A horizontal screw 44 is installed on the crossbeam 43 through the horizontal groove. A mounting seat 45 is set on the horizontal screw 44 located in the horizontal groove. The vertical screw 42 is rotatably connected to the vertical frame 41 and threadedly connected to the crossbeam 43. The crossbeam 43 slides on the vertical frame 41. The horizontal screw 44 is rotatably connected to the crossbeam 43 and threadedly connected to the mounting seat 45. A handwheel is set at the end of both the vertical screw 42 and the horizontal screw 44. By rotating the vertical screw 42, the height of the crossbeam 43 is adjusted. By rotating the horizontal screw 44, the welding gun 5 on the mounting seat 45 is aligned with the weld seam of the door frame and the door panel.

[0029] The working principle and usage process of this utility model are as follows: The variable speed motor 24 drives the left and right helical screws 21 to rotate. The left and right helical screws 21 push the support plates 23 to move relative to each other under the support of the guide column 22, so that the spacing between the support plates 23 meets the placement requirements of the door frame width. The door frame and door panel, which are spot-welded together, are placed on the support rollers 25 between the support plates 23. The height of the crossbeam 43 is adjusted by rotating the vertical screw 42. The welding gun 5 on the mounting base 45 is aligned with the weld seam of the door frame and door panel by rotating the horizontal screw 44. The servo motor 32 drives the reciprocating screw 31 to rotate, so that the reciprocating screw 31 pushes the sliding seat 33 and the push plate 34 to push the door frame to move to the rear. At the same time, the welding gun 5 welds the weld seam on both sides of the door frame.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
