Protecting door for numerically controlled machine tool

Abstract

The invention discloses a protecting door for a numerically controlled machine tool. The protecting door comprises a door body. A lubricating oil tank is mounted on the top of the door body, a connecting wheel is mounted in a connecting notch, an adjusting wheel is mounted below the connecting wheel, a moving wheel is mounted below the adjusting wheel, a movable gear is mounted on one side of theconnecting plate through a rotary shaft, and a cleaning brush is coaxially mounted below the moving gear. The protecting door disclosed by the invention is scientific and reasonable in structure and safe and convenient to use. Sliding friction of the protecting door which moves is converted into rolling friction through the moving wheel, so that resistance subjected to the protecting door when theprotecting door moves is reduced, and meanwhile, lubricating oil of the lubricating oil tank is discharged through a liquid outlet hole of a hollow shaft and is effectively adsorbed to the surfaces of the adjusting wheel and the moving wheel, so that the side face of the moving wheel is coated with lubricating oil all the way when the moving wheel slides, the friction force of the protecting doorwhich moves is smaller, and the protecting door is pushed conveniently. Meanwhile, noise generated when the moving wheel slides is reduced, so that a high quality workshop environment is constructedconveniently better.

Problems solved by technology

[0003] The invention provides a protective door for numerically controlled machine tools, which can effectively solve the problem that the protective door in the current market has a simple structure and after a long time of use, the friction force increases during the sliding process, causing the protective door to slide slowly and make noise when sliding. The increase is not conducive to the construction of a high-quality workshop environment. The water used for cooling is easy to adhere to the surface of the observation glass in the middle of the protective door, causing the glass surface to be blurred, so that observers cannot effectively observe the working status of the CNC machine tool through the observation glass, and it is difficult to timely Discovering unexpected conditions during the cutting process and stopping the CNC machine tool in time will cause damage to the cutting tool and the workpiece. In order to prevent the side wall of the protective door from directly colliding with the fuselage, rubber gaskets will be installed on the side wall of the existing protective door, but this It is difficult to effectively remove the rubber-like gasket after it is damaged. At the same time, the installation process of the rubber gasket is cumbersome, which is not conducive to quick replacement to ensure that the protective door can continue to be used. When the protective door is damaged or needs to be repaired, it is necessary to replace the top and bottom of the protective door. At the same time, it is taken out from the chute. The moving process not only requires the carrier to have good physical strength, but also is prone to collision damage between the protective door and the fuselage due to the carrier's inability to hold it firmly, which is not conducive to the quick disassembly and maintenance of the protective door. When the CNC machine tool is in use, the chute at the bottom of the protective door is in a low position, and dust and cutting debris often enter, making it difficult for the protective door to slide effectively.
