[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] A scroll compressor base assembly welding device comprises a base plate, a welding seat is fixedly connected to the center of the upper side of the base plate, a top seat is fixedly arranged at the center of the upper surface of the welding seat, a top plate is lifted and lowered above the base plate, a pressing die assembly for pressing the compressor base onto the top seat is arranged at the center of the top plate, and unloading assemblies for unloading the compressor base are arranged on both sides of the base plate.

[0007] As a further optimization solution of the utility model, the die assembly includes a welding groove opened in the center of the top plate, and a pressure seat is installed on the lower side of the welding groove through fixing screws.

[0008] As a further optimization solution of the utility model, six welding holes evenly distributed around the circumference are provided on the pressure seat, and the lower surface of the pressure seat is lower than the lower surface of the top plate.

[0009] As a further optimization scheme of the utility model, the unloading assembly includes unloading cylinders fixedly arranged on both sides of the bottom plate, and the output ends of the two unloading cylinders are fixedly connected with unloading plates for unloading the compressor base from the top seat.

[0010] As a further optimization solution of the utility model, mounting plates are fixedly provided on both sides of the bottom plate, and a pressure welding cylinder for driving the top plate to move up and down is fixedly connected to one side of the mounting plate.

[0011] As a further optimization solution of the utility model, a first positioning rod is provided at an eccentric position on the upper side of the top seat, and four second positioning rods are provided on the upper circumference of the welding seat.

[0012] The beneficial effect of the utility model is that in the utility model, the scroll compressor base is installed on the welding seat and the top seat, and then the top plate is driven to descend by the pressure welding cylinder, so that the pressure seat in the center of the top plate first presses the scroll compressor base together, and then the scroll compressor base is welded through six welding holes through the welding equipment above, thereby improving the welding quality of the scroll compressor base and thus improving the service life of the scroll compressor base.
