[0030] like Figure 1-4 As shown, the utility model provides an iron plate welding table, which has a workbench 1, wherein four columns 2 are fixedly installed on the workbench 1, and the top walls of the columns 2 are each provided with a semicircular groove 21, and the top wall of the left column 2 is each installed with a semicircular cover 22 by screws;

[0031] It also has a welding frame 3 for placing iron plates. Cylindrical blocks 31 are fixedly installed on the left and right sides of the front and rear walls of the welding frame 3. The four cylindrical blocks 31 are respectively arranged corresponding to the four semicircular grooves 21.

[0032] The cylindrical block 31 on the left is rotatably connected to the corresponding semicircular groove 21 and the semicircular cover 22, and the cylindrical block 31 on the right is movably connected to the corresponding semicircular groove 21. A vertically arranged slide 32 is fixedly installed in the middle of the rear wall of the welding frame 3.

[0033] Optionally, in the above technical solution, two support columns 4 are fixedly installed on the workbench 1 and located on the rear side of the welding frame 3, a horizontal plate 41 is fixedly installed on the support column 4, a horizontal dovetail groove 42 is opened on the top surface of the horizontal plate 41, and a dovetail slider 43 is connected to the sliding inside the dovetail groove 42.

[0034] Optionally, in the above technical solution, a support block 44 is fixedly installed on the dovetail slider 43, one end of a connecting rod 45 extending toward the welding frame 3 is fixedly installed on the support block 44, the other end of the connecting rod 45 is rotatably connected to a rotating sleeve 451, a slide 46 is fixedly installed on the rotating sleeve 451, and the slide plate 32 is slidably connected in the slide 46.

[0035] Optionally, in the above technical solution, the fixed end of the telescopic cylinder 47 is fixedly installed on the right end of the dovetail slide 42, and the movable end of the telescopic cylinder 47 extends to the left, and the end is fixedly connected to the dovetail slider 43.

[0036] Optionally, in the above technical solution, the middle parts of the left and right ends of the welding frame 3 are rotatably connected with a rotating shaft 51 that passes through its side wall, and two bases 5 are fixedly installed on the outer bottom wall of the welding frame 3. A reduction motor 50 is fixedly installed on the base 5, and the output shaft of the reduction motor 50 is connected to the rotating shaft 51 on the same side through a coupling.

[0037] Optionally, in the above technical solution, a U-shaped frame 52 is fixedly installed near one end of the rotating shaft 51, and a threaded hole is opened on the top wall of the U-shaped frame 52. A screw 53 is threadedly connected in the threaded hole, and the bottom end of the screw 53 is connected to a pressure plate 54 through a bearing.

[0038] Among them, the distance from the left inner wall to the right inner wall of the welding frame 3 is the length dimension, and the distance from the front inner wall to the rear inner wall is the width dimension. The length and width dimensions of the welded iron plate are smaller than the length and width dimensions of the welding frame 3;

[0039] Among them, half of the width of the welding frame 3 is slightly smaller than the height of the column 2, which is convenient for turning over the iron plate to be welded.

[0040] The bottom end of the screw 53 is fixedly connected to the inner circumference of the bearing, and the outer circumference of the bearing is fixedly mounted on the pressure plate 54. The top wall of the pressure plate 54 is provided with a through hole for mounting the bearing.

[0041] Working principle:

[0042] When in use, the two iron plates to be welded are placed into the U-shaped frame 52 on the same side, and the screw 53 is screwed to move it along the threaded hole of the U-shaped frame 52 and drive the pressing plate 54 downward through the bearing until the pressing plate 54 and the bottom wall of the U-shaped frame 52 clamp the iron plates at the same time;

[0043] After the welding of this side of the two iron plates (set this side as the front side) is completed, the reduction motor 50 is started to drive the rotating shaft 51 to rotate, thereby driving the iron plates clamped by the U-shaped frame 52 and the pressure plate 54 to rotate 180 degrees, and the back sides of the two iron plates are welded. When both sides of the iron plates are welded, the iron plates are turned 90 degrees along the left side of the welding frame 3 so that the iron plates are perpendicular to the state during welding, and the welds on both sides are checked and compared;

[0044] In the initial state, the movable end of the telescopic cylinder 47 is fully retracted, at which time the dovetail slider 43 is located at the center of the dovetail chute 42, the slide 46 and the slide plate 32 are in a vertical state, and the welding frame 3 is in a horizontal state (such as Figure 3 );

[0045] During the flip, the telescopic cylinder 47 is activated to extend its movable end, driving the dovetail slider 43 to move leftward, thereby driving the connecting rod 45 on the support block 44 to move leftward, and the rotating sleeve 451 drives the slide 46 to move leftward following the connecting rod 45, and the slide 46 and the sliding plate 32 in sliding connection restrict each other;

[0046] Therefore, when the rotating sleeve 451 moves to the left, it first rotates counterclockwise along the connecting rod 45, driving the slide 46 fixedly connected thereto to rotate counterclockwise. Under the action of the slide 46, the slide plate 32 simultaneously rotates counterclockwise and slides toward the upper end and left end of the slide 46, driving the welding frame 3 to rotate counterclockwise.

[0047] Since the cylindrical block 31 on the left side of the welding frame 3 is rotatably connected to the semicircular groove 21 and the semicircular cover 22, the cylindrical block 31 on the left side rotates in place, causing the right end of the welding frame 3 to lift up, resulting in a counterclockwise rotation;

[0048] When the telescopic cylinder 47 fully extends its movable end, the dovetail slider 43 slides to the left, the slide 46 and the slide plate 32 are in a horizontal state, and the welding frame 3 is in a vertical state (such as Figure 4 ).

[0049] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
