Description

Technical Field

[0001] The utility model belongs to the technical field of welding tools, and in particular relates to a welding tool for an isolation transformer box bracket. Background Art

[0002] The isolation transformer box refers to the box of the transformer that protects the input winding and the output winding with electrical isolation. Its outer periphery is provided with four horizontally protruding ears, and the ears are provided with mounting holes that pass through from top to bottom. The isolation transformer box is positioned and installed by the bracket. Figure 1 The specific structure of the isolation transformer box bracket includes two first horizontal steel bars 91, two second horizontal steel bars 92 and four screw rods 93 arranged in the up and down direction. The first horizontal steel bar 91 and the second steel bar 92 are welded vertically to each other to form a well-shaped frame structure, and the well-shaped frame structure includes a rectangular frame located at its center, and the four screw rods 93 are respectively welded at the four corners of the inner side of the rectangular frame. The well-shaped frame structure is also welded with a first reinforcing rib 94 parallel to the first horizontal steel bar 91 and a second reinforcing rib 95 parallel to the second horizontal steel bar 92 at the horizontal periphery. During installation, the screw rod 93 passes through the mounting hole on the hanging ear of the isolation transformer box, and the hanging ear is positioned and installed on the screw rod 93 through the positioning nuts arranged in pairs up and down, and the installation height of the isolation transformer box is adjusted by adjusting the position of the nut on the screw rod 93. Due to the insufficient welding accuracy of the isolation transformer box, the isolation transformer box body is often unable to be smoothly installed on its bracket. Unqualified isolation transformer boxes need to be corrected or scrapped, which wastes manpower and material resources and reduces construction efficiency.

[0003] When welding the isolation transformer box bracket, first draw a line on the welding workbench, refer to the line on the workbench to preset the horizontal steel bars, weld the first horizontal steel bar 91, the second horizontal steel bar 92, the first reinforcing rib 94 and the second reinforcing rib 95 into a preset base with a rectangular frame structure, and finally weld the screw rod 93 to the four corners inside the rectangular frame. The above welding operation requires two operators to cooperate with each other to complete, one of whom holds the two pre-welded parts together by hand to position them to avoid the parts from shifting during the welding process, and the other operator performs the welding operation. The above welding operation method not only wastes manpower, but also the manual hand-held horizontal steel bars easily deviate from the marked lines, resulting in a large relative position deviation between the horizontal steel bars, which makes the horizontal relative position deviation between the screw rods 93 positioned by the rectangular frame structure too large; manual hand-held screw rods 93 for welding result in a large deviation in the welding verticality of the screw rods 93.

[0022] When in use, first place two first horizontal steel bars 91 between two first stoppers 2, the two first horizontal steel bars 91 are arranged at intervals along the first horizontal direction and respectively abut against the first stoppers 2; place two second horizontal steel bars 92 between two second stoppers 3, the two second horizontal steel bars 92 are arranged at intervals along the second horizontal direction and respectively abut against the second stoppers 3; the two first horizontal steel bars 91 and the two second horizontal steel bars 92 are arranged adjacent to each other up and down to form a well-shaped frame structure. The screw rod positioning member 5 positions the screw rod 93 in the horizontal direction, the lower end of the screw rod 93 is located at the four inner corners of the rectangular frame on the well-shaped frame, and the base 1 abuts against the lower end of the screw rod 93 to limit the screw rod 93 in the upper and lower directions. At this time, the two screw rods 93 arranged at intervals along the first horizontal direction cooperate with the second stoppers 3 to clamp and position the second horizontal steel bars 92, and the two screw rods 93 arranged at intervals along the second horizontal direction cooperate with the first stoppers 2 to clamp and position the first horizontal steel bars 91. The first horizontal steel bar 91, the second horizontal steel bar 92 and the screw rod 93 are welded to form the main body of the isolation transformer box support, and finally the reinforcing ribs are welded on the periphery of the tic-tac-toe frame structure. The reinforcing ribs can also be welded before the screw rod 93 is welded.

[0023] The utility model sets a base 1 to limit the horizontal steel bar and the screw rod 93 in the upper and lower directions, sets a screw rod positioning member 5 to limit the screw rod in the horizontal direction, so that the screw rod 93 cooperates with the first stopper 2 and the second stopper 3 to clamp and position the first horizontal steel bar 91 and the second horizontal steel bar 92 in the horizontal direction, ensures the relative position of the first horizontal steel bar 91, the second horizontal steel bar 92 and the screw rod 93 during the welding process, ensures the verticality of the screw rod 93 relative to the horizontal steel bar, and improves the welding accuracy of the isolation transformer box bracket body.

The screw rod positioning member 5 can be made of flat steel welded end to end. As a further preference, the base 1 is also provided with a positioning sleeve 8, and the positioning sleeve 8 is provided with a lower end positioning hole 81 coaxially arranged with the upper end positioning hole 51.

The positioning sleeve 8 can be an integral structure formed integrally with the base 1, or it can be a ring plate fixedly mounted on the base 1. In order to save processing procedures and costs, a flat gasket for screw installation of national standard is generally used.
