Ultrahigh pressure water jet-based compressor housing opening and disassembling equipment and control method of equipment

Abstract

The invention discloses ultrahigh pressure water jet-based compressor housing opening and disassembling equipment and a control method of the equipment. The equipment is characterized in that a first horizontal base and a second horizontal base are respectively arranged at the two adjacent side edges of a horizontally arranged rectangular water collecting trough; a revolving platform is arranged on the first horizontal base; a compressor to be disassembled is horizontally clamped on one side of the revolving platform capable of rotating in a vertical plane; the compressor is driven to rotate by a revolving servo motor by the revolving platform; a working platform capable of moving in the X-axis and the Y-axis is arranged on the second horizontal base; a horizontal cantilever is arranged along the Z-axis by using the working platform; an ultrahigh pressure water jet cutter nozzle is vertically mounted at the front end of the horizontal cantilever; and a cutting point is formed on a housing of the compressor by an ultrahigh water jet formed by the water jet cutter nozzle. According to the equipment and the control method, a laser ranging sensor is used for real-time detection, and the water jet nozzle is controlled to automatically follow the shape of the housing in the circumferential direction of the compressor according to a detection signal, so that the housing opening on compressors with various shapes can be realized accurately.

Description

technical field [0001] The invention relates to a compressor shell opening and dismantling device and a control method thereof. Background technique [0002] Compressors are the core components of refrigerators and air conditioners. Whether it is to repair, remanufacture or recycle the copper, iron, aluminum and other materials in it, it is necessary to open its casing. It is difficult to manually open the shell to meet the welding requirements after repair. Many faulty compressors whose lifespan has not yet ended can only be scrapped due to the lack of a special machine for opening the shell; for the recycling of compressors, manual disassembly is inefficient and unsafe. Due to the permanent dismantling, the internal components of the compressor can only be recycled as raw materials, and cannot be remanufactured and reused, resulting in a serious waste of resources. [0003] For compressors used in refrigerators and air conditioners, the shell is usually stretched and weld...

AI Technical Summary

Problems solved by technology

However, the operating cost of the related equipment is high, the energy consumption is high, the noise is loud, and the wear is serious during the crushing process; the shell cannot be reused due to the crushing method, and the reuse of the internal parts of the compressor cannot be guaranteed due to the crushing operation at extremely low temperature

[0005] 2. Plasma arc cutting: the cutting speed is fast, but because the shell of the compressor is not a flat steel plate, but a rotating body, it is difficult to ensure a constant distance between the cutting torch and the surface of the shell during the cutting process. Hitting the case will burn out the expensive electrodes

During the plasma arc cutting process, the high-speed airflow will blow the molten metal slag into the interior of the compressor, causing inconvenience to subsequent remanufacturing or recycling, and even burning the internal wires

[0006] 3. Flame cutting: Its cost is low and the speed is fast, but due to the injection of the gas jet, sparks, molten beads and iron slag splash
