Description

Technical Field

[0001] The utility model relates to the technical field of welding and positioning of a stainless steel gas box for a switch cabinet, in particular to a stainless steel gas box welding tool. Background Art

[0002] The switch cabinet is a fully insulated and fully sealed metal-enclosed switchgear. Its high-voltage live parts are all sealed in a stainless steel gas box, isolating the switch cabinet from the influence of external environmental factors such as air pollution, moisture, and small animals. The protection level of the gas box reaches IP67, and the annual gas leakage rate is ≤0.01%, so the requirements for gas box welding are very high.

[0003] At present, the traditional argon arc welding commonly used in welding gas boxes mainly uses the burning arc between the continuously fed welding wire and the workpiece as the heat source, and the gas sprayed from the nozzle protects the arc for welding. The argon arc welding has the disadvantages of slow welding speed, easy deformation, large weld bead and weld point that need grinding, and unsightly weld. Laser welding is a method of welding that uses the heat generated by the focused laser beam as energy to bombard the weldment. It has the advantages of fast speed, high precision, small deformation of the workpiece, wide application range, high degree of automation, and beautiful appearance. Compared with traditional welding technology, it has higher production efficiency and better welding quality, and has received more and more attention and application in recent years.

[0004] However, laser welding has high requirements on the neatness, verticality, weld density and adhesion of the gas box component panels. It is difficult to meet the matching accuracy requirements by simply relying on manual welding of panels, which affects the quality of welding. In addition, the external dimensions after welding have large deviations, poor air tightness and low qualified rate of finished products. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a stainless steel gas box welding tool, which can facilitate the assembly and welding of the gas box. During assembly, the relative positions of various panels of the gas box are accurate, which can meet the airtightness requirements, effectively save manpower and improve production efficiency.

[0006] In order to solve the above technical problems, the technical solutions adopted are as follows:

[0007] A stainless steel gas box welding tool, characterized in that it includes a base, two side panel limit frames and multiple tube positive magnets, the lower ends of the two side panel limit frames are respectively hinged to the two sides of the base, and the two side panel limit frames are correspondingly arranged, and limit columns are respectively provided on both sides of the side panel limit frames, and the limit columns are provided with side panel limit openings extending in the up and down directions, and the side panel limit openings are at right angles and face inwards; the base and the limit columns are both made of magnetic metal, and when the gas box bottom plate is placed on the base and the gas box side plates are inserted into the side panel limit frames, the tube positive magnets are adsorbed to the base through the gas box bottom plate or adsorbed to the limit columns through the gas box side plates.

[0008] When the above-mentioned stainless steel gas box welding tool is used to assemble the gas box, the gas box bottom plate is first placed on the base; then the gas box side plates are respectively placed in the two side plate limit frames, and then the two side plate limit frames are closed and fixed. At this time, the lower end of the side plate limit opening is in contact with the top angle of the base, so the side plate limit frame is perpendicular to the base; then the remaining two gas box side plates are inserted in turn. In the process of inserting the gas box side plates one by one, the top angles of the two adjacent gas box side plates can be engaged in the side plate limit openings of the corresponding limit columns. After alignment, the tube positive magnets are installed in turn, so that the tube positive magnets are adsorbed with the base through the gas box bottom plate or the gas box side plates are adsorbed with the limit columns to fix the position of the gas box side plates until the positions of each gas box side plate are neat and accurate; finally, the joint seams of the gas box bottom plate and the gas box side plates are welded to complete the gas box assembly. This stainless steel gas box welding tool can fix each panel of the gas box, and the relative position of each panel of the gas box is more precise, which can better meet the air tightness requirements of the gas box. Only one person is needed to be responsible for the splicing, positioning, calibration and welding operations of the entire gas box, reducing manpower and improving production efficiency.

[0009] In the above-mentioned inside-outside direction, when the limiting column is erected, the position facing the air box is inside, and the position away from the air box is outside.

[0010] In a preferred embodiment, the side plate limit frame includes two limit columns and at least one first connecting beam, the lower ends of the two limit columns are hinged to the two sides of the base, and the two ends of the first connecting beam are respectively connected to the two limit columns. The first connecting beam connects the two limit columns in the same side plate limit frame to ensure the correct position of the limit columns and avoid affecting the accuracy of air box assembly. Usually, the upper and lower ends of the limit columns are respectively connected to the first connecting beam.

[0011] In a further preferred embodiment, the limiting column is composed of two limiting plates, and the two limiting plates are perpendicular to each other and form the side plate limiting opening at a right angle.

[0012] In a further preferred embodiment, each of the position limiting plates is provided with a plurality of observation holes, which are arranged in sequence along the length direction of the position limiting plates. By providing the observation holes, it is possible to observe from top to bottom whether the joint seams of the air box side plates are aligned, thereby ensuring that the welding requirements are met.

[0013] In a preferred embodiment, the stainless steel gas box welding tool further comprises two connectors that can respectively connect the two sides of the two side plate limit frames. The connectors can connect the two side plate limit frames when the side plate limit frames are erected, and can also limit the side plates of the gas box.

[0014] In a further preferred embodiment, the connecting member includes at least one second connecting crossbeam, and both ends of the second connecting crossbeam are detachably connected to the limiting columns on the corresponding side of the two side plate limiting frames.

[0015] Usually, the base is a rectangular frame composed of four metal columns. When assembling the air box, the air box bottom plate is directly placed on the rectangular frame. Pin holes are opened on the side of the rectangular frame and the corresponding limit plate. When the side plate limit frame is erected, the two pin holes are aligned. It is only necessary to use a pin to pass through the two pin holes in sequence to fix the position of the side plate limit frame. Furthermore, the lower ends of the two limit columns in the same side plate limit frame are connected to a first connecting beam, and the lower ends of the two corresponding limit columns in different side plate limit frames are connected to a second connecting beam. These first connecting beams and second connecting beams are located above the four sides of the rectangular frame, and can limit the air box bottom plate from all sides.

[0016] The beneficial effect of the utility model is that the stainless steel gas box welding tool can facilitate the assembly and welding of the gas box. During assembly, the relative positions of the various panels of the gas box are accurate, which can meet the airtightness requirements, effectively save manpower and improve production efficiency.
