[0002] A compressor is a driven fluid machine that boosts low-pressure gas to high-pressure gas, and is the heart of the refrigeration system. Compressors are divided into piston compressors, screw compressors, centrifugal compressors, linear compressors, etc. Piston compressors are generally composed of a housing, an electric motor, a cylinder, a piston, a control device, and a cooling system. If the motor stator inside the compressor is damaged, it needs to be disassembled and replaced, and there is currently no efficient disassembly tool. Utility Model Content

[0003] The purpose of the present application is to provide a compressor stator disassembly tool to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a compressor stator disassembly tool, comprising a cross steel, a long rod, a jack, a disc and a pad, wherein two symmetrically arranged long rods are fixedly installed on the cross steel, and two jacks are symmetrically fixedly installed on the cross steel. The disc is sleeved on the outer periphery of the compressor casing, and the disc is threadedly connected to the compressor cover mounting position by bolts. The opposite sides of the disc are provided with a platform fixed thereto, and the platform is fixedly connected to the jack by a pad, one end of the long rod extends into the inner cavity of the compressor, and a crescent hook is fixedly installed on the end of the long rod extending into the inner cavity of the compressor, and the crescent hook is adapted to hook the platform of the stator in the compressor.

[0005] Preferably, the long rod is detachably fixed on the cross steel via a locking nut.

[0006] In summary, the technical effects and advantages of the utility model are:

[0007] In the utility model, the stator is hooked by the crescent hook of the long rod. During the lifting process of the jack, the horizontal steel moves upward to drive the long rod to pull out the stator inside the compressor, thereby realizing the separation of the stator and the compressor casing. The utility model has a simple structure, convenient operation and improved maintenance efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
