Rotating shaft welding fixture of drawer seat drive mechanism of low-voltage switch board

Abstract

The invention discloses a rotating shaft welding fixture of a drawer seat drive mechanism of a low-voltage switch board, which has the technical scheme that a locating square bar is fixed in a square groove on a soleplate, both ends and the middle of the locating square bar are provided with locating notches, a guide block corresponding to small segment gears and a position locating block corresponding to big segment gears are fixed on the locating notches, a gear angle locating block is fixed in the position locating block, and a locating slide rod is fixed in the guide block; two shaft angle locating blocks are fixed on the soleplate between the position locating block and the guide block, and the side faces of the shaft angle locating blocks are fixed with a shaft direction locating block matched with a lantern ring groove on a rotating shaft; two clamps are respectively fixed on the two shaft angle locating blocks and are distributed at two sides of the two small segment gears, and two springs are arranged under the locating slide rod and are opposite to the two small segment gears in the vertical direction; the four segment gears are clamped and welded once, thereby enhancing the welding precision and having precise location and convenient and quick clamp.

Description

technical field [0001] The invention relates to the technical field of low-voltage electrical equipment processing, in particular to a rotating shaft welding fixture for a drive mechanism in a drawer seat of a low-voltage power distribution cabinet. Background technique [0002] Such as figure 1 , four sector gears are welded on the shaft 19 of the drive mechanism of the drawer seat of the low-voltage power distribution cabinet, that is, two small sector gears 12 in the middle and two large sector gears 10 at both ends. These four sector gears not only have angular positions Requirements, and there are relative position requirements in the axial direction of the rotating shaft 19, therefore, the welding fixture must ensure the angle and position relationship of the four sector gears, and must also leave the necessary welding space for the welding torch, when all the gears After all welding is completed, the rotating shaft 19 must be able to be easily taken out from the fixt...

AI Technical Summary

Problems solved by technology

[0003] The defects of the fixture currently used are: 1. Use the tooth shape of the gear to locate the angular relationship. Although the angular position relationship can be determined accurately, it is very inconvenient to clamp the gear and the clamping efficiency is low; 2. During production, only Two gears can be welded at one time, and then the other two gears can be clamped and welded twice, but the angle and position accuracy of the four gears cannot be guaranteed
