Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of numerical control processing, in particular to a demisting system for a protective door of numerical control equipment. Background Art
[0002] During the CNC equipment processing, it is necessary to always pay attention to the processing status of parts and tool wear. However, when the cutting fluid is turned on, the tempered glass of the protective door will fog up, blocking the line of sight. Opening the protective door for observation is extremely dangerous. However, most domestic CNC equipment currently does not have a demisting function.
[0003] According to traditional processing methods, there are two main measures to observe the processing status of parts and tool wear. One is to open the protective door for direct observation. This measure is extremely dangerous and is the main observation method for mid- and low-end CNC equipment. The other is to use a "rotating window". This measure is relatively expensive and has a limited observation angle. It is mainly used in high-end CNC equipment and is not easy to popularize. Utility Model Content

A spirally arranged conical nozzle pipeline is provided inside the nozzle 6.
[0007] Furthermore, the self-locking switch 3 is connected to an external numerical control device, and the on and off of the self-locking switch is controlled by the numerical control device.
[0008] Furthermore, the adapter 5 is connected to the system gas pipeline 4 by threaded connection or welding.

The present invention is in no way limited to any specific arrangement and method set forth below, but rather covers any improvements, replacements, and modifications of structures, methods, and devices without departing from the spirit of the present invention. In the accompanying drawings and the following description, well-known structures and techniques are not shown to avoid unnecessary ambiguity in the present invention.
[0021] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other, and the embodiments can refer to and quote each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0022] like Figure 1 As shown, the utility model proposes a demisting system for the protective door of CNC equipment, including a pneumatic speed regulating joint 2, a self-locking switch 3, a system air pipeline 4, an adapter 5, and a nozzle 6. One end of the pneumatic speed regulating joint 2 is connected to the external pipeline 1, and the other end is connected to the self-locking switch 3, the adapter 5, and the nozzle 6 in sequence through the system air pipeline 4. A spirally arranged conical nozzle pipeline is arranged inside the nozzle 6.
[0023] The external pipeline 1 is connected to the system pipeline 4 through the pneumatic speed regulating joint 2 to form an integral system, and the air pressure of the system pipeline 4 is controlled by the speed regulating function of the pneumatic speed regulating joint 2, thereby indirectly controlling the gas flow rate at the nozzle 6.
[0024] Among them, the external pipeline 1 and the system gas pipeline 4 can be set as flexible pipelines, so that the positions of the pneumatic speed regulating joint 2, self-locking switch 3, adapter 5, and nozzle 6 in the system can be adjusted according to the injection requirements.
[0025] The self-locking switch 3 can control the on / off operation of the entire air circuit system, and by selecting its self-locking and inching modes, the system can be operated continuously or in inching mode. The self-locking switch 3 is connected to an external CNC device, which controls the on / off of the self-locking switch. In addition, a magnet is fixed to the self-locking switch 3 to form a magnetic self-locking switch. The magnet's magnetic attraction can be used to attach the self-locking switch 3 to any metal part of the CNC device, facilitating the adjustment of the injection position of the CNC device.
[0026] Among them, the system gas line 4 is connected to the nozzle 6 through the adapter 5. Since it has a magnetic device, it can be firmly adsorbed on the surface of the equipment and can be freely moved to meet different processing needs. The two ends of the system gas line 4 for installing the adapter 5 can be provided with a threaded structure, and the adapter 5 is also provided with a corresponding threaded structure. The two are connected by threads, which is convenient for installation and disassembly. In addition, the two ends of the system gas line 4 for installing the adapter 5 can be provided as welding parts, and the adapter 5 is welded to the system gas line 4 to achieve a fixed connection between the two. In addition, a magnet block can also be fixed on the adapter 5 to form a magnetic adapter. The adapter 5 can be installed on any metal part of the CNC equipment through the magnetic effect of the magnet, which is convenient for adjusting the injection position of the CNC equipment.
[0027] Among them, the nozzle 6 has a 35° trapezoidal plate structure, and a spirally arranged conical nozzle pipeline is set inside. Through this structural feature, a fan-shaped air outlet demisting area can be realized, thereby increasing the demisting area and achieving a uniform and extensive demisting effect.
[0028] The inlet diameter of the spirally arranged conical nozzle pipeline is 0.3mm, and the outlet diameter is 0.1mm. The taper of the conical nozzle pipeline changes from the inlet to the outlet, that is, the inlet taper gradually decreases by 0.25° to the outlet taper. The 0.3mm and 0.25° spiral conical distributed air outlets can achieve the effects of boosting and rectifying the outlet wind speed; the 0.25° conical hole structure increases the pressure by gradually reducing the inner hole volume according to the pressure-volume formula P=F / V, thereby achieving a boosting effect; and the cone hole has a spiral structural feature, which can make the outlet wind speed have a spiral feature, thereby increasing the contact area with the protective door and enhancing the demisting effect.
[0029] The system in this utility model is specifically designed for machine tool construction and consists of a pneumatic speed control connector 2, an 8mm external air line 1, a self-locking switch 3, an adapter 5, and a nozzle 6. The pneumatic speed control connector 2, constructed of stainless steel, primarily connects to the machine tool's air system and controls the air flow rate of the demisting system, controlling the air velocity of the nozzle 6 and thus indirectly controlling the demisting intensity. The 8mm external air line 1 shares the same specifications as the internal air line 4, ensuring good versatility.
[0030] This magnetic self-locking switch consists of a powerful rubidium magnet and a pneumatic switch with a self-locking function. It is primarily used to control the start and stop of a system. The rubidium magnet and the self-locking switch are fixed together to create a strong magnetic field, allowing the entire switch to attach to the CNC machine bed. The switch can be freely moved to suit the machine structure and the operator's size, facilitating operation. The self-locking switch has both inching and self-locking functions, allowing for flexible switching based on production needs.
[0031] This magnetic adapter consists of a powerful rubidium magnet and a pneumatic adapter. It's primarily used to connect air pipes to adjustable, flat-tipped, bamboo-shaped blower nozzles. The rubidium magnet and pneumatic adapter are secured to the adapter, creating a strong magnetic connection that allows it to attach to the CNC machine bed and be moved to any desired position based on the operator's viewing position.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the field can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present invention, and these modifications or replacements should all be included in the protection scope of the present invention.
