New energy automobile water-cooled motor shrinkage fit assembly machine

Abstract

The invention belongs to the field of mechanical devices and provides a new energy automobile water-cooled motor shrinkage fit assembly machine. The machine comprises a workbench of which an upper endis provided with an inner cylinder placing table, an outer cylinder placing table which is arranged on the workbench and is provided with a heating pipe and a heating barrel, and a supporting frame which is arranged on the workbench and is provided with a moving assembly, wherein the heating pipe is arranged in the heating barrel, a clamping jaw is arranged at a lower end of the moving assembly,and the clamping jaw is located above the heating barrel. Compared with the prior art, the shrinkage fit assembly machine has the advantages that a motor outer cylinder can be heated and expanded, a motor inner cylinder and the motor outer cylinder can be assembled conveniently, and water channels in the motor inner cylinder and the motor outer cylinder are prevented from being damaged.

Description

technical field [0001] The invention belongs to the field of mechanical devices, and in particular relates to a new energy automobile water-cooled motor shrink-fit assembly machine. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels, the use of new vehicle power devices), integrated vehicle power control and advanced technology in driving, the formation of advanced technical principles, with New technologies, new structures of vehicles, and new energy vehicles drive motors are mostly water-cooled. Water-cooled cooling requires flow passages in the motor barrel for liquid flow. In order to ensure the sealing of the flow passages, the motor inner cylinder and the motor outer casing are required The barrel is an interference fit, but this makes the assembly of the inner barrel and the outer barrel more difficult, and easily causes damage to the inner barrel or the outer ba...

Problems solved by technology

[0002]New energy vehicle refers to the use of unconventional vehicle fuel as the power source (or the use of conventional vehicle fuel, the use of new vehicle power devices), the power of the integrated vehicle Advanced technologies in control and drive form vehicles with advanced technical principles, new technologies and new structures. Most of the drive motors of new energy vehicles are cooled by water. Water cooling requires flow channels in the motor barrel for liquid flow. In order to ensure the sealing of the flow channel, the inner cylinder of the motor and the outer cylinder of the motor are required to be an interference fit, but this makes the assembly of the inner cylinder and the outer cylinder more difficult, and it is easy to cause damage to the inner cylinder or the outer cylinder
