Description

Technical Field

[0001] This invention relates to the field of household appliance recycling technology, and in particular to an automatic disassembly device for compressor rotor assemblies and its usage method. Background Technology

[0002] In the resource recycling industry, the rotor base of a refrigeration compressor is made of cast iron, while the connecting shaft that fixes the rotor is made of different materials such as cast iron and steel. The middle part of the rotor is made of silicon steel sheets, and two aluminum rings at both ends are riveted to the silicon steel sheets. Rotor bases are roughly divided into three types based on their materials: cast iron, aluminum, and silicon steel sheets. To maximize the value of recycled resources, these three materials need to be completely separated during dismantling operations to achieve maximum utilization.

[0003] The current disassembly method involves breaking the rotor and base connecting shaft from the rotor assembly. During the disassembly process, the existing process involves inverting the base on a special mold, and using a hydraulic device to push a stamping rod to separate the rotor and fixed shaft from the base. The rotor and connecting shaft are then crushed using a crusher. However, because the strength of the connecting shaft is inconsistent with that of the silicon steel sheets and aluminum rings, the first-pass yield is low during the crushing process. Some parts that do not meet the sorting requirements need to be processed a second time, resulting in high crushing costs. Furthermore, during repeated processing, cast iron and aluminum parts generate powder, which is difficult to sort again. Aluminum and iron account for a 1.5% loss, indicating room for improvement in recycling rate and cost. During rotor disassembly, the hydraulic push rod is controlled by foot. When the hands and feet are not coordinated for a long time, the hand may still be on the rotor assembly when the hydraulic push rod is activated, posing a certain safety hazard.

[0004] Chinese invention patent announcement number CN110380558B discloses a motor rotor assembly and its disassembly and assembly method. A three-jaw puller is used to pull the assembled side abutment, inner abutment, and bearing together off the shaft. In use, the screw tip of the three-jaw puller is positioned in the center hole of the shaft end face, and the three jaws of the puller hook onto three recessed parts. After pulling out, an external hexagonal ring is used to separate the side abutment from the inner abutment and bearing. At this point, only the inner abutment and the bearing with an interference fit to it remain. A press is used to press out the inner abutment to separate them. Finally, a press is used to eject the rotor from the shaft. This method relies on the cooperation of a three-jaw puller and a press, making it cumbersome, time-consuming, and labor-intensive. Summary of the Invention

[0005] The technical problem this invention aims to solve is that existing rotor assembly disassembly lacks specialized equipment, poses safety hazards during operation, has a low recycling rate of disassembled products, and results in low disassembly efficiency. To address this, this invention provides an automatic compressor rotor assembly disassembly device and its usage method that reduces production safety hazards, increases the recycling rate of disassembled products, significantly improves production efficiency, and reduces disassembly operation costs.

[0006] The technical solution of this invention is: an automatic compressor rotor assembly disassembly device, comprising: a rectangular housing; a hydraulic cylinder installed at one end of the rectangular housing; a disc base located inside the rectangular housing and connected to the hydraulic cylinder; three screws, one end of which is fixedly connected to the disc base, and the other ends of which extend towards the other end of the rectangular housing; and a three-jaw chuck installed at the other end of the rectangular housing, with the jaws of the chuck hinged to the other ends of the three screws, and one side of the chuck exposed. Outside the rectangular housing; a movable chuck, located outside the three-jaw chuck, with a central hole in its center; several push rods, one end of which is fixed to the movable chuck, and the other end extending through the three-jaw chuck towards the disc base; a cylinder, fixed to the top of the rectangular housing; a connecting rod, one end of which is fixed to the piston rod of the cylinder, and the other end extending into the rectangular housing; a telescopic rod, comprising a slidingly fitted outer tube and an inner tube, the outer tube being hinged to the connecting rod, and the outer tube corresponding to the central hole of the three-jaw chuck.

[0007] The improvement of the above scheme is that a number of limiting blocks are distributed on the disc base, and the number of limiting blocks corresponds one-to-one with the other end of the number of push rods.

[0008] The inner wall of the central hole in the above scheme is provided with serrations.

[0009] The three jaws of the three-jaw chuck described in the above scheme are equipped with serrations.

[0010] A further improvement to the above scheme is that a vertically distributed first partition is fixedly connected inside the rectangular box, the first partition is slidably engaged with three screws and several push rods, and the inner tube is fixedly connected to the center of the first partition.

[0011] A further improvement to the above scheme is that a vertically distributed second partition is fixed inside the rectangular box, and the second partition slides in conjunction with three screws, an outer tube, and several push rods.

[0012] The method of using the automatic compressor rotor assembly disassembly equipment includes the following steps: Place the compressor rotor assembly to be disassembled on the outside of the moving chuck, align the rotor with the center of the moving chuck, start the hydraulic cylinder to drive the disc base and three screws to move, thereby driving the three jaws to close and clamp the rotor, and several push rods pass through the three-jaw chuck to push the moving chuck outward, separating the base of the compressor rotor assembly from the fixed shaft and the rotor.

[0013] The beneficial effects of this invention are that it adjusts the operation sequence. After the material loading personnel load the material, they press the operation switch, and the equipment begins to fix the main rotor and push the base to separate from the rotor, which greatly improves the safety of operation. It has the advantages of high product recovery rate, high production efficiency, low cost, and reduced labor intensity of operators. Attached Figure Description

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments implemented by those skilled in the art without creative effort are within the protection scope of the present invention.

[0016] like Figure 1-3The automatic compressor rotor assembly disassembly device includes: a rectangular housing 1; a hydraulic cylinder 2, which is installed at one end of the rectangular housing; a disc base 3, which is located inside the rectangular housing and is connected to the hydraulic cylinder; three screws 4, one end of which is fixed to the disc base, and the other end of which extends to the other end of the rectangular housing; and a three-jaw chuck 5, which is installed at the other end of the rectangular housing and whose jaws are hinged to the other ends of the three screws, with one side of the three-jaw chuck protruding from the rectangular housing. In addition; a movable chuck 6, located outside the three-jaw chuck, with a central hole in the center of the movable chuck; three push rods 7, one end of which is fixedly connected to the movable chuck, and the other end extending through the three-jaw chuck towards the disc base; a cylinder 8, fixedly connected to the top of the rectangular housing; a connecting rod 9, one end of which is fixedly connected to the piston rod of the cylinder, and the other end extending into the rectangular housing; and a telescopic rod 10, comprising a slidingly fitted outer tube and an inner tube, the outer tube being hinged to the connecting rod, and the outer tube corresponding to the central hole of the three-jaw chuck.

[0017] The method of using the automatic compressor rotor assembly disassembly equipment includes the following steps: Place the compressor rotor assembly to be disassembled on the outside of the moving chuck, align the rotor with the center of the moving chuck, start the hydraulic cylinder to drive the disc base and three screws to move, thereby driving the three jaws to close and clamp the rotor, and several push rods pass through the three-jaw chuck to push the moving chuck outward, separating the base of the compressor rotor assembly from the fixed shaft and the rotor.

[0018] As a preferred example of the present invention, such as Figure 4-5 As shown, three limiting blocks 11 are distributed on the disc base. Each of the limiting blocks corresponds to the other end of the three push rods. The function of the limiting blocks is to limit the movement distance of the disc base. When the limiting block contacts the other end of the push rod, the hydraulic cylinder stops.

[0019] As another preferred embodiment of the present invention, the inner wall of the central hole is provided with serrations, which can securely clamp the rotor.

[0020] As another preferred embodiment of the present invention, such as Figure 6-7 As shown, in order to increase the biting force of the jaws, the three jaws of the three-jaw chuck are provided with serrations.

[0021] In another preferred embodiment of the present invention, a vertically distributed first partition 12 is fixedly connected inside the rectangular box. The first partition is slidably engaged with three screws and three push rods. The inner tube is fixedly connected to the center of the first partition. The function of the first partition is to provide guidance and support for the three screws and push rods, so that the disc base, the three screws, and the three push rods move smoothly. When the base of the compressor rotor assembly is separated from the fixed shaft and the rotor, the cylinder is activated. The cylinder drives the outer tube of the telescopic rod to move towards the center of the three-jaw chuck where the rotor is clamped. At the same time, the disc base moves in the opposite direction, so that the three screws drive the three jaws of the three-jaw chuck to release the rotor, and the outer tube pushes the rotor out.

[0022] As another preferred embodiment of the present invention, a vertically distributed second partition 13 is fixedly connected inside the rectangular box. The second partition is slidably engaged with the three screws, the outer tube and several push rods. The second partition has the same function as the first partition, providing guidance and support for the three screws and push rods, so that the disc base, the three screws and the three push rods move smoothly.
