Problems solved by technology
[0005] In order to make up for the deficiencies of the existing technology and solve the welding residual stress caused by the uneven temperature change and the uneven heating of the base metal near the weld seam during the welding seam cooling process of the prior art, the higher welding Residual stress will reduce the strength of the weld and at the same time reduce the fatigue strength of the weld. A new energy vehicle electric scroll compressor manufacturing method proposed by the present invention

The invention belongs to the technical field of compressors, and specifically relates to a method for manufacturing an electric scroll compressor for a new energy vehicle. The welding equipment used in the method includes a platform; a welding torch is fixedly connected to one side of the platform, and the welding torch is connected to a wire feeding mechanism and a power supply. Mechanism connection; No. 1 sliding hole is provided on the other side of the platform, and a sliding column is slidably connected to the No. 1 sliding hole, and a group of conical circular platforms are evenly distributed on the bottom circumference of the sliding column; the platform on the side of the No. 1 sliding hole is connected through the rotation of the bracket. There is a turntable, the turntable is driven by a motor, and the motor is connected to the power supply through the controller; the turntable is fixedly connected with a revolving pin near the outer edge, and the revolving pin is connected with a swing rod, which hits the top of the sliding column when the swing rod rotates; the present invention uses the swing rod Drive the sliding column to hammer the weld to reduce the welding stress and increase the fatigue strength of the weld.
Description
technical field [0001] The invention belongs to the technical field of compressors, in particular to a manufacturing method of an electric scroll compressor for a new energy vehicle. Background technique [0002] A scroll compressor is a volumetric compression compressor, and the compression components are composed of a moving scroll and a static scroll. A number of structural features are included to allow for a shunt flow of gas through the compressor casing to reduce oil entrainment. [0003] After entering the casing, some of the gas flows upward to reduce the amount of gas flowing downward towards the oil. To achieve this, the motor of the compressor may be surrounded by a sleeve having upper and lower holes for directing air flow to the upper and lower stator end turns of the motor. In some embodiments, it is important to position the suction inlet relative to the two gas passages between the stator and the motor housing. The inlet is positioned such that a channel ...
