[0003] At present, in the prior art, due to different thicknesses of sheet metal used by different cabinets, the position and clamping angle of sheet metal cannot be positioned when clamped by traditional clamp, since the cabinet is composed of five sheet metal plates combined with each other, and there are eight gaps at the butt joint of the five sheet metal plates, if there is an angle deviation when two sheet metals are welded, it will cause the subsequent sheet metals to have position deviation or welding angle deviation, which will reduce the welding precision, and then affect the size of the entire switchgear cabinet body.

[0004] Therefore, the utility model provides a kind of welding fixture of sheet metal cabinet. UTILITY MODEL CONTENTS

[0005] Therefore, the utility model solves the technical problem that in the prior art, when welding two sheet metals, multiple sheet metal angles cannot be controlled, which easily causes the welding angle of sheet metal to deviate, which reduces the welding precision, and then affects the size of the entire switchgear cabinet body.

[0006] To solve the above technical problems, this utility model provides a welding fixture for a sheet metal cabinet, including a sheet metal welding table and a sheet metal cabinet movably overlapping the top outer surface of the sheet metal welding table. A slider 1 is movably sleeved on the top outer surface of the sheet metal welding table and located on the inner wall of the sheet metal cabinet. A corner extrusion positioning unit is provided on the outer surface of the slider 1. The corner extrusion positioning unit includes a motor 2 fixedly installed on the top outer surface of the slider 1. A support column is fixedly connected to the output end of the motor 2. A swing arm is swayingly connected to the outer surface of the support column and located at the bottom edge. A hydraulic rod is swayingly sleeved on the outer surface of the support column and located at the middle position of the swing arm. A limit rail and a motor 3 are fixedly installed on the outer surface of the support column and located at the top edge. A slider 2 located on the inner wall of the limit rail is threadedly sleeved on the output end of the motor 3. An L-shaped extrusion plate is fixedly connected to the outer surface of the slider 2.

[0007] A sliding rail is provided on the top surface of the sheet metal welding table at the middle position, and a lifting welding machine is fixedly installed on the top surface of the sheet metal welding table at the middle position.

[0008] In one embodiment of the present invention, a gap is provided at the joint between the two overlapping limiting plates, and the outer surface of the slider one slides onto the top surface of the sliding track.

[0009] In one embodiment of the present invention, the outer surface of the overlapping limiting plate is slidably overlapped with the outer surface of the L-shaped extrusion plate, and the bottom surface of the overlapping limiting plate is movably overlapped with the top surface of the swing arm.

[0010] In one embodiment of the present invention, a support frame is fixedly installed on the top surface of the sheet metal welding station and at the two side edges.

[0011] In one embodiment of the present invention, a motor is fixedly installed on the outer surface of the support frame and at the upper and lower edges.

[0012] In one embodiment of the present invention, a conveyor belt is movably sleeved on the outer surface of the output end of the motor.

[0015] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0016] The welding fixture for sheet metal cabinets described in this utility model, when welding sheet metal of different thicknesses, first places the sheet metal in the gap between the overlapping limiting plate and the L-shaped extrusion plate. When placing the sheet metal, the swing arm simultaneously limits the position of the sheet metal to overlap, and then the edges of the sheet metal are fitted together. Then, the limiting track rotates, causing the slider two to move towards the overlapping limiting plate on the output end of the motor three and the surface of the limiting track. The L-shaped extrusion plate on the output end of the motor three fits against the gap of the sheet metal, and the overlapping limiting plate and the L-shaped extrusion plate fix the sheet metal together.

[0017] This utility model describes a welding fixture for a sheet metal cabinet. A slider slides on the surface of a sliding track, and a lifting welding machine moves vertically along the joints of the sheet metal to weld them. While the slider moves the sheet metal cabinet, the lifting welding machine welds the seams at the top of the overlapping sheet metal sections. A motor rotates a support column to weld seams at different positions and angles on the sheet metal.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0028] Reference Figures 1 to 7 As shown, a welding fixture for a sheet metal cabinet according to this utility model includes a sheet metal welding table 11 and a sheet metal cabinet 12 movably overlapping the top outer surface of the sheet metal welding table 11. A slider 13 is movably sleeved on the top outer surface of the sheet metal welding table 11 and located on the inner wall of the sheet metal cabinet 12. A corner pressing and positioning unit is provided on the outer surface of the slider 13. The corner pressing and positioning unit includes a motor 131 fixedly installed on the top outer surface of the slider 13. A support column 132 is fixedly connected to the output end of the motor 131. A swing arm 133 is oscillatingly connected to the outer surface of the support column 132 and located at the bottom edge. A hydraulic rod 1310 is oscillatingly sleeved on the outer surface of the support column 132 at the middle position and located on the outer side of the swing arm 133. A limit track 138 and a motor 136 are fixedly installed on the outer surface of the support column 132 at the top edge position. A slider 137 is movably sleeved on the output end of the motor 136 at the inner wall of the limit track 138. An L-shaped extrusion plate 139 is fixedly connected to the outer surface of the slider 137. A limit sleeve 134 is provided on the outer surface of the swing arm 133. An overlapping limit plate 135 is movably sleeved on the outer surface of the limit sleeve 134.

[0029] A sliding rail 111 is provided on the top surface of the sheet metal welding table 11 at the middle position, and a lifting welding machine 116 is fixedly installed on the top surface of the sheet metal welding table 11 at the middle position.

[0030] When welding sheet metal of different thicknesses, the sheet metal is first placed in the gap between the overlapping limiting plate 135 and the L-shaped extrusion plate 139. When placing the sheet metal, the swing arm 133 simultaneously limits the position of the sheet metal to overlap. Then, the edges of the sheet metal are fitted together. The limiting rail 138 is rotated, causing the slider 137 to move towards the overlapping limiting plate 135 on the output end of the motor 136 and the surface of the limiting rail 138. The L-shaped extrusion plate 139 on the output end of the motor 136 fits against the gap of the sheet metal. The overlapping limiting plate 135 and the L-shaped extrusion plate 139 are used to fix the sheet metal together. This allows for clamping and fixing of four sheet metal pieces and the gaps on the sheet metal surface, while also controlling the angle of the sheet metal joint.

[0031] The slider 13 slides on the surface of the sliding track 111, and the lifting welding machine 116 moves vertically to the joints of the sheet metal, thereby welding the seams. While the slider 13 moves the sheet metal cabinet 12, the lifting welding machine 116 welds the seams at the top of the overlapping sheet metal. Then, the motor 131 rotates the support column 132 to weld seams at different positions and angles on the sheet metal. After welding the 8 seams on 5 sheet metal pieces, the hydraulic rod 1310 extends and pushes the swing arm 133 to swing, causing the swing arm 133 to swing. The overlapping limiting plate 135 on one end of 33 moves away from the outermost side of the sheet metal, and at the same time, the motor 136 rotates to move the L-shaped extrusion plate 139 away from the inner corner of the sheet metal. When there is no obstruction plate on the surface of the sheet metal, the welded sheet metal cabinet 12 is taken out from the inside of the overlapping limiting plate 135 and the L-shaped extrusion plate 139. This achieves the effect of quickly taking out the welded sheet metal, avoiding the need for traditional clamps to fully compress and fix the inner and outer sides of the sheet metal, so that after the sheet metal is welded, tension will be formed on the surface of the clamp, making it impossible to take the sheet metal out quickly.

[0032] Furthermore, such as Figures 1 to 7As shown, a gap is provided at the joint between the two overlapping limiting plates 135. The outer surface of the slider 13 slides and overlaps with the top surface of the sliding track 111. The outer surface of the overlapping limiting plate 135 slides and overlaps with the outer surface of the L-shaped extrusion plate 139. The bottom surface of the overlapping limiting plate 135 movably overlaps with the top surface of the swing arm 133. A support frame 112 is fixedly installed on the top surface of the sheet metal welding table 11 and at the two side edges. A motor 113 is fixedly installed on the outer surface of the support frame 112 and at the upper and lower side edges. A conveyor belt 114 is movably sleeved on the outer surface of the output end of the motor 113. An anti-slip strip 115 is fixedly connected to the outer surface of the conveyor belt 114. The outer surface of the anti-slip strip 115 movably overlaps with the outer surface of the slider 13.

[0033] During operation, after the sheet metal welding is completed, the slider 13 moves along the surface of the sliding track 111 to the middle position of the support frame 112, and then detaches from the surface of the sheet metal cabinet 12 through the clamp. At this time, the motor 113 rotates the conveyor belt 114. When the conveyor belt 114 rotates, the anti-slip strips 115 on its surface will adhere to the surface of the sheet metal cabinet 12. The curvature and anti-slip force of the anti-slip strips 115 increase the adhesion between the anti-slip strips 115 and the sheet metal cabinet 12, so that the sheet metal cabinet 12 gradually moves upward. After the sheet metal cabinet 12 is completely detached from the support column 132, the staff can take the sheet metal cabinet 12 down. This achieves the effect of using the detachment device to lift and push the sheet metal cabinet 12 upward, so that the staff can easily take the sheet metal cabinet 12 down without having to lift it.

[0034] Working principle: When welding sheet metal of different thicknesses, the sheet metal is first placed in the gap between the overlapping limiting plate 135 and the L-shaped extrusion plate 139. When the sheet metal is placed, the swing arm 133 simultaneously limits the position of the sheet metal to overlap. Then, the edges of the sheet metal are fitted together. The limiting track 138 rotates, causing the slider 137 to move towards the overlapping limiting plate 135 on the output end of the motor 136 and the surface of the limiting track 138. The L-shaped extrusion plate 139 on the output end of the motor 136 fits against the gap of the sheet metal. The overlapping limiting plate 135 and the L-shaped extrusion plate 139 fix the sheet metal together, thus clamping and fixing four sheet metal pieces and the gaps on the sheet metal surface, while controlling the angle of the sheet metal joint.

[0035] The slider 13 slides on the surface of the sliding track 111, and the lifting welding machine 116 moves vertically to the joints of the sheet metal, thereby welding the seams. Furthermore, as the slider 13 moves the sheet metal cabinet 12, the lifting welding machine 116 welds the seams at the top of the overlapping sheet metal sections. Then, the motor 131 rotates the support column 132 to weld seams at different positions and angles on the sheet metal. After welding 8 seams on 5 sheet metal sections, the hydraulic system... The rod 1310 is pushed and extended, which in turn pushes and swings the swing arm 133, causing the overlapping limiting plate 135 on one end of the swing arm 133 to move away from the outermost side of the sheet metal. At the same time, the motor 136 rotates, moving the L-shaped extrusion plate 139 away from the inner corner of the sheet metal. When there is no obstruction plate on the surface of the sheet metal, the welded sheet metal cabinet 12 is taken out from the inside of the overlapping limiting plate 135 and the L-shaped extrusion plate 139, achieving the effect of quickly taking out the welded sheet metal.

[0036] After the sheet metal welding is completed, the slider 13 moves on the surface of the sliding track 111 to the middle position of the support frame 112, and then detaches from the surface of the sheet metal cabinet 12 by the clamp. At this time, the motor 113 rotates the conveyor belt 114. When the conveyor belt 114 rotates, the anti-slip strips 115 on its surface will adhere to the surface of the sheet metal cabinet 12. The curvature and anti-slip force of the anti-slip strips 115 increase the adhesion between them and the sheet metal cabinet 12, so that the sheet metal cabinet 12 gradually moves upward. After the sheet metal cabinet 12 is completely detached from the support column 132, the staff can take the sheet metal cabinet 12 down. This achieves the effect of using the detachment device to lift and push the sheet metal cabinet 12 upward, so that the staff can easily take the sheet metal cabinet 12 down without having to lift it.

[0037] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
