[0021] It should be noted that the terms "first", "second", etc. in the description and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence, so that the embodiments of this application described here, based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of this application.

[0022] Reference Figure 1-Figure 3 A screw compressor rotor disassembly device includes a U-shaped frame 14, one side of the U-shaped frame 14 is provided with two slide grooves 10, and two support plates 13 for placing the compressor are slidably connected in the two slide grooves 10. A driving component is provided in the slide groove 10 to move the support plate 13 in the slide groove 10. The driving component drives the support plate 13 to move in the slide groove 10, and the distance between the two support plates 13 changes during the movement of the support plate 13 in the slide groove 10, so that the distance between the two support plates 13 meets the size of the compressor, and then the compressor is placed on the two support plates 13;

[0023] A support frame 7 is welded to the upper surface of the support plate 13, and a slot 15 is provided on one side of the support frame 7. A slider 17 is slidably connected in the slot 15. Two guide rods 6 are welded to the top of the slider 17. The top of the guide rod 6 passes through the support frame 7 and is welded with a connecting frame 4. A mounting hole is provided on the top of the connecting frame 4, and a pressure block 2 is fixed in the mounting hole by bolts. A pressing component for pushing the pressure block 2 to move downward is provided on the upper surface of the U-shaped frame 14, and a spring 16 is provided in the slot 15, and the two ends of the spring 16 are respectively fixed to the slider 17 and the support frame 7. During the movement of the support plate 13, the support frame 7 will be driven to move, and the support frame 7 will drive the connecting frame 4 to move through the guide rod 6, and the connecting frame 4 will drive the pressure block 2 to move. As the volume of the compressor increases, the distance between the yin and yang rotors will also increase proportionally, thereby changing the distance between the two pressing blocks 2 to correspond to the yin and yang rotors. Subsequently, the pressing assembly is pressed to move the pressing block 2 downward, and the pressing block 2 will push the guide rod 6 downward through the connecting frame 4. The guide rod 6 will drive the slider 17 to move downward, and the slider 17 will squeeze the spring 16, so that the pressing block 2 squeezes the rotor and disassembles the rotor, so that the rotors of compressors of the same model but different sizes can be disassembled, thereby improving the use effect of the disassembly device. When the pressing block 2 squeezes the rotor out and the rotor disassembly is completed, the pressing block 2 will automatically reset by the force of the spring 16, so that it is convenient to disassemble the rotor next time.

[0024] In the present invention, the driving components are two threaded rods 9, which are respectively rotatably connected in the two slide grooves 10, and the threaded rods 9 pass through the support plate 13 and are threadedly engaged with the support plate 13. One end of the two threaded rods 9 passes through the U-shaped frame 14 and is welded with a knob. A positioning column 12 is welded on one side of the support plate 13, and the positioning column 12 passes through the U-shaped frame 14 to make the support plate 13 move horizontally. By rotating the threaded rod 9, the threaded rod 9 will drive the support plate 13 to move in the slide groove 10 through the threaded engagement between the threaded rod 9 and the support plate 13, and the support plate 13 will drive the positioning column 12 to move. Since the positioning column 12 passes through the U-shaped frame 14, the support plate 13 can be moved horizontally. One end of the positioning column 12 is welded with a baffle 11 to resist the positioning column 12, and the positioning column 12 blocks the support plate 13 during the movement. The plate 11 will resist, thereby preventing the positioning column 12 from detaching from the U-shaped frame 14. The pressing assembly includes a fixing frame 8, which is welded to the upper surface of the U-shaped frame 14. The cylinder 5 is fixed in the fixing frame 8 by bolts. One end of the pneumatic rod of the cylinder 5 is fixed with a pressure plate 3 by bolts, and the pressure plate 3 is in contact with the pressure block 2. When the cylinder 5 is started and contracts, the pressure plate 3 is driven to move downward. The pressure plate 3 will press the pressure block 2 to move downward, so that the pressure block 2 presses the rotor to disassemble. Two clamping blocks 18 for positioning the compressor are welded on the upper surface of the support plate 13. When the compressor is placed, the clamping block 18 will position the compressor, leaving space for disassembly of the rotor. A rubber block 1 is bonded to the bottom of the pressure block 2, and the rubber block 1 is the same length as the pressure block 2. The rubber block 1 can prevent the pressure block 2 from causing damage to the rotor.

[0025] Working principle: When it is needed, rotate the threaded rod 9, and the threaded rod 9 will drive the support plate 13 to move in the slide 10 through the threaded engagement between the threaded rod 9 and the support plate 13, and the support plate 13 will drive the positioning column 12 to move. Since the positioning column 12 passes through the U-shaped frame 14, the support plate 13 can be moved horizontally, and the distance between the two support plates 13 will change during the movement of the support plate 13 in the slide 10, so that the distance between the two support plates 13 meets the size of the compressor, and then the compressor is placed on the two support plates 13. At this time, the clamping block 18 will position the compressor, thereby leaving space for disassembly of the rotor, and the support plate 13 will drive the support frame 7 during the movement. The support frame 7 will move by driving the connecting frame 4 through the guide rod 6, and the connecting frame 4 will drive the pressure block 2 to move. As the volume of the compressor increases, the distance between the yin and yang rotors will also increase proportionally, thereby changing the distance between the two pressure blocks 2 to correspond to the yin and yang rotors. Then the cylinder 5 contracts and drives the pressure plate 3 to move downward, and the pressure plate 3 presses the pressure block 2 to move downward. The pressure block 2 will push the guide rod 6 downward through the connecting frame 4, and the guide rod 6 will drive the slider 17 to move downward. The slider 17 will squeeze the spring 16, so that the pressure block 2 squeezes the rotor to disassemble the rotor, so that the rotors of compressors of the same model but different sizes can be disassembled, thereby improving the use effect of the disassembly device.

Those skilled in the art will understand that the present invention is not limited to the above embodiments, and more modifications can be made according to the teachings of the present invention.
