Compressor protecting rack and welding method thereof

Abstract

The invention discloses a compressor protecting rack and a welding method thereof. The protecting rack is connected with a housing of a compressor; through holes communicating with the housing are formed in the protecting rack; a waterproof reinforcement is connected to a part above the through holes in the protecting rack; the protecting rack is welded with the housing through an upper welding point arranged above the waterproof reinforcement and lower welding points arranged below the through holes; the welding method of the compressor protecting rack realizes reliable welding of the compressor protecting rack and the housing; a space separation method is adopted, the welding points of the protecting rack are distributed above the waterproof reinforcement and below the through holes, andthe reliable and stable welding of the protecting rack and the housing is realized; and the production efficiency is high, the cost is reduced, the welding strength is high, the protecting reinforcements have an effective waterproof effect, and the waterproof effect is good.

Description

technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to a compressor protective frame and a welding method thereof. Background technique [0002] There are two types of compressor protective frames in the prior art. For example, the Chinese patent document with the authorized announcement number CN 206098290 disclosed "an integrated relay protective frame" on April 12, 2017, which has a rear opening with a back hole. There are upper baffles, lower baffles, left baffles and right baffles around the backboard, and the baffles are used for waterproofing. The baffles will have problems such as excessive size during the stamping process, and the waterproof effect will deteriorate. [0003] The other is as Figure 6 As shown in the protective frame of the compressor, there is a raised protective rib located outside the wiring hole on the protective frame. The protective rib plays the role of connecting the protective frame a...

AI Technical Summary

Problems solved by technology

At the same time, a very large current is required to ensure the welding strength during the welding process. The problems caused by high current; one is that the shell will be welded through and cause failure, and the other is that the heat generated by the high current will cause serious damage to the electrode, and it is often necessary to adjust the welding Upper and lower electrodes and electrode replacement, low production efficiency

If the current changes slightly, there will be problems of weak welding and falling off, which seriously affects product quality and user satisfaction, low production efficiency and high cost
