And hydraulic spanner, be provided with the first screw and the second screw on the base plate, first bolt through first screw with
The housing connection of the compressor, second bolt is fixedly connected through second screw with the driven screw of compressor；
The inwall of one end of the sleeve is provided with the tooth bank being engaged with the outside alveolus of the nut of compressor, the other end be provided with
The first through hole that the hydraulic spanner is engaged；The second through hole passed through for sleeve is additionally provided with the base plate.
The sleeve includes cylindrical tube and the top board being arranged at the top of the cylinder, and the tooth bank is along the cylinder
The internal wall equally distributed square protruding of circumferencial direction.
The first through hole is arranged on the top board.
The first through hole is square opening.
Handle is provided with the outer wall of the sleeve.
Centralizer is provided with around second through hole, the centralizer is at least three set along second through hole
Floor.
Also include gate frame, the gate frame includes unclamping first that nut provides force support for hydraulic spanner
Support, nut is tightened for hydraulic spanner the second support frame of force support is provided and connects the first support frame and the second support frame
The link for connecing, first support frame and the second support frame are arranged on the base plate, first support frame and described
The distance at two support frames to the center of second through hole is equal.
Using above technical scheme, the present invention achieves following technique effect：
Frock provided by the present invention for dismounting the nut of screw compressor, it can be by the spiral shell of screw compressor
Mother is dismounted, time saving and energy saving.
Brief description of the drawings
Fig. 1 is the structure chart of compressor nut dismounting tool of the present invention；
Fig. 2 is the perspective structure figure of the sleeve of compressor nut dismounting tool of the present invention.
