Welding paste smearing device of pre-welding procedure of exhaust pipe of upper shell of air conditioner compressor

Abstract

The invention relates to the field of air conditioner devices, in particular to a welding paste smearing device of a pre-welding procedure of an exhaust pipe of an upper shell of an air conditioner compressor. The welding paste smearing device of the pre-welding procedure of the exhaust pipe of the upper shell of the air conditioner compressor comprises a base, a box, a smearing device body and a welding paste conveying device. The box is arranged over the base. The upper end face of the base is provided with a lifting device for driving the box to ascend and descend. A stirring device is arranged in the box. The welding paste conveying device comprises a transverse tube, a spiral feeding threaded rod and a spiral drive mechanism. The two ends of the transverse tube are fixedly connected with the spiral feeding threaded rod and the stirring device correspondingly. The spiral feeding threaded rod vertically penetrates through the bottom of the box to be arranged at the position over an installation hole, for installation of the exhaust pipe, of the upper shell. The smearing device body is in transmission fit with the bottom end of the spiral feeding threaded rod. The smearing device body comprises a welding paste smearing mechanism and a rotation drive mechanism used for driving the welding paste smearing mechanism to rotate around the spiral feeding threaded rod. The welding paste smearing device achieves automatic smearing of the welding paste, the procedures are conducted together, the smearing efficiency of the welding paste is improved, and the problem that smearing is uneven is solved.

Description

technical field [0001] The invention relates to the field of air-conditioning equipment, in particular to a solder paste applicator for the front-end welding process of an exhaust pipe on an upper casing of an air-conditioning compressor. Background technique [0002] Nowadays, when installing the exhaust pipe on the upper casing of the air-conditioning compressor, solder paste will be applied around the installation hole of the exhaust pipe on the upper casing. The solder paste generally uses silver solder paste, and the initial state of the silver solder paste is powder It needs to be mixed with water to form a thick paste, and then manually applied. The process of applying is cumbersome and inefficient. When manually applying, it cannot be applied evenly, resulting in uneven welding quality. Contents of the invention [0003] The object of the present invention is to address the deficiencies of the prior art and provide a solder paste applicator for the welding front-en...
