The vertical and horizontal are all referred to in this disclosure with reference to the placement position of the device when in use; moreover, vertical, horizontal or vertical is not specifically meant to be absolute vertical, absolute horizontal and absolute vertical, but may have some error.
Referring to fig. 1, the present embodiment provides a welding apparatus assembly, which is mainly used for vertically welding a connecting rod to a bottom plate 4; it includes welding equipment and welding frock. The welding tool is used for correcting the relative position of the connecting rod and the bottom plate 4 so that the connecting rod is perpendicular to the bottom plate 4; the welding device is used for welding the corrected connecting rod and the bottom plate 4. The welded connecting rod can be used for fixedly connecting a compressor of an external machine of the air conditioner.

The upper end face of the lower electrode 6 is provided with a mounting hole, the bottom surface of the mounting hole is horizontally arranged, and the inner diameter of the mounting hole is larger than the outer diameter of the connecting rod. The design ensures that the connecting rod has a certain activity allowance in the mounting hole, so that the connecting rod can be in a vertical state when the lower end surface of the connecting rod is matched with the bottom surface of the mounting hole; and the connecting rod is convenient to assemble and disassemble with the lower electrode 6, so that the overall efficiency is improved.
The welding fixture comprises a horizontal detection device 3 and a horizontal adjustment device 5, wherein the horizontal detection device 3 is mainly used for detecting whether the bottom plate 4 is horizontally placed, and the horizontal adjustment device 5 is used for adjusting the height of one side of the bottom plate 4 so as to enable the whole bottom plate 4 to be kept horizontal. In the embodiment, the level detection device 3 adopts a three-way digital display level detection device 3; it comprises a circular flat plate 8, three support posts 7 and three digital display level detection devices 3. Three struts 7 are vertically connected to the lower surface of the flat plate 8 and are detachably connected with the flat plate 8; the digital display level detection device 3 is arranged on the upper surface of the round flat plate 8. The three support posts 7 are magnetic posts, and the flat plate 8 is an iron plate, so that the support posts 7 are connected with and detached from the flat plate 8 conveniently.
The horizontal detection device 3 with the structure has certain universality and is simple and convenient to operate; both for the leveling of the three lower electrodes 6 and for the leveling of the base plate 4. The support posts 7 are removed when the three lower electrodes 6 are leveled. When the leveling device is used for leveling the bottom plate 4, as the whole bottom plate 4 is a sheet metal part, other rib plate structures are arranged on the surface of the bottom plate; the flat plate 8 is directly placed on the bottom plate 4, and is required to be supported by the support posts 7 because interference of the rib plate structure is difficult to keep horizontal.

in order to ensure that the welded bolt rod is vertical to the bottom plate 4, and further reduce noise after the compressor is connected with the bottom plate 4; before welding, it is necessary to level the three lower electrodes 6 so that their upper ends are on the same horizontal plane. The area to be welded of the base plate 4 is then placed on the upper ends of the three lower electrodes 6, the other end of the base plate 4 is supported by the horizontal adjustment means 5, and the base plate 4 is brought into a horizontal position by adjusting the supporting heights of the two adjustment bars. The bottom plate 4 is provided with through holes for mounting the connection bars, and at this time, the through holes on the bottom plate 4 should be made to correspond to the positions of the lower electrodes 6. After leveling, the connecting rod passes through the through hole on the bottom plate 4 and is arranged in the mounting hole on the lower electrode 6, and the bottom surface of the mounting hole on the lower electrode 6 is horizontally arranged; thus, when the end surface of the connecting rod is engaged with the bottom surface of the mounting hole, the connecting rod is maintained in a vertical position. At this time, the connection bar is kept perpendicular to the bottom plate 4. The upper electrode 2 is dropped and then welded.
The welding equipment assembly has the beneficial effects that:
the research on the complaint of noise caused by vibration of a compressor in an air conditioner outdoor unit is that a connecting rod on a bottom plate 4 of the outdoor unit and the bottom plate 4 have a certain inclination angle; since the height of the connecting rod for fixing the compressor is relatively high, the position error of the upper end thereof is relatively large even at a small inclination angle. The device assembly can improve the perpendicularity of the connecting rod and the bottom plate 4, so that vibration noise of the compressor can be effectively reduced. And, because there is a certain activity allowance between the pore wall of the mounting hole in the lower electrode 6 and the connecting rod, can improve the overall operation efficiency in the course of operation. In addition, the bottom of the horizontal detecting device 3 is provided with a magnetic support column 7, so that the horizontal detecting device 3 can be commonly used when the lower electrode 6 is leveled and the bottom plate 4 is leveled, and the support column 7 is convenient and simple to assemble and disassemble.

In addition, in the present embodiment, the connecting rod adopts a bolt rod, and is not limited thereto in other embodiments.
Example 2:
the present embodiment provides a welding method of the connecting rod and the bottom plate 4, which adopts the welding apparatus assembly in embodiment 1; the method comprises the following steps:
a. punching holes in the bottom plate 4 in advance for welding connecting rods; the upper ends of the three lower electrodes 6 are leveled so as to be on the same horizontal plane.
b. Placing the area to be welded of the bottom plate 4 on the lower electrode 6, and placing the other end of the bottom plate 4 on the horizontal adjusting device 5; adjusting the supporting height of the horizontal adjusting device 5 so that the bottom plate 4 reaches a horizontal state; a through hole is formed in the region to be welded and is arranged above the lower electrode 6;
c. the connecting rod passes through the through hole on the bottom plate 4 and is arranged in the mounting hole of the lower electrode 6, so that the connecting rod is vertically arranged;
d. the upper electrode 2 is dropped to contact the connecting rod, and the connecting rod and the bottom plate 4 are welded.
For step a, if the bottom plate 4 has been perforated before, the step of perforating may be omitted; if the three electrodes are already leveled when shipped, the leveling step for the electrodes may also be omitted.
The welding method has the beneficial effects that:
the whole step of the welding method is simple to operate, and the technical level requirement on workers is low; the perpendicularity of the welded connecting rod and the bottom plate 4 can be effectively improved by adopting the method, and vibration noise of the compressor is effectively reduced.
