Embodiment Construction
[0039] The present invention will be further described below in conjunction with accompanying drawing.
[0040] An embodiment of the assembly tooling of the isolating switch shaft welding and the crank arm of the present invention is as follows: Figure 3 to Figure 13As shown, it includes a base 20 in the form of a flat plate, and the base 20 is provided with two rotating shaft positioning blocks 2 arranged at intervals before and after. V-groove for positioning. The two rotating shaft positioning blocks 2 form a rotating shaft positioning structure for the rotating shaft in the rotating shaft weldment 12 to be rotatably arranged and positioned radially and axially. The top of each rotating shaft positioning block 2 is respectively provided with two threaded holes, and the corresponding pressure plate 6 can be fixed in the threaded holes on the rotating shaft positioning block 2 through the screw rod 5, so as to realize the clamping of the rotating shaft and avoid the rotatio...

The invention relates to a disconnecting switch rotating shaft welding and connecting lever assembling tool. The disconnecting switch rotating shaft welding and connecting lever assembling tool comprises a base, a rotating shaft positioning structure enabling a rotating shaft to be rotationally arranged during rotating shaft welding and achieving positioning in the radial and axial direction is arranged on the base, the tool is further provided with a connecting lever positioning block for positioning a connecting lever, and a connecting lever positioning pin for being positioned and insertedinto a pin hole in the connecting lever is arranged on the connecting lever positioning block; the base is further provided with a dial and indication marks, wherein the dial is rotationally assembledand used for being arranged coaxial with a flange plate welded to the rotating shaft, and the indication marks are used for indicating scales of the dial, and the dial is provided with a flange platepositioning pin for being positioned and inserted into a connecting hole in the flange plate. By adopting the technical scheme, conversion between the peripheral position of the flange plate and theperipheral position of the dial can be achieved, then, quantified adjustment of the flange plate can be achieved by peripheral quantified adjustment of the flange plate, the tool is suitable for anglechanges of connecting lever and rotating shaft welding, and the assembling requirement for various product structures is met.
Description
technical field [0001] The invention relates to an assembly tool for the welding of a rotating shaft of a disconnector and a crank arm. Background technique [0002] A high-voltage AC isolating switch is an important device in a power station. A typical structure of the switch is an outdoor three-column high-voltage AC isolating switch disclosed in a Chinese patent with the authorized announcement number CN201112252Y. The switch side pole 96 on both sides of the direction, the input and output porcelain bottle between the switch side pole 96 and the switch middle pole 95 is provided with a rotating porcelain bottle, the main knife 91 is fixed on the rotating porcelain bottle, and the two ends of the main knife 91 are provided with the switch side pole 96, The corresponding conductive card slot of the static contact on the middle pole 95 of the switch is connected with the manual mechanism of the main knife through the main knife transmission mechanism to rotate the porcelain...
