According to the dust-proof device, the negative pressure pump is started to form a negative pressure space in the circular channel, so that suction force is generated to suck metal dust and air in the dust-proof cover into the circular channel and then discharge the metal dust and the air through the chip removal pipe and the hose, and in the process that the air in the dust-proof cover is sucked into the circular channel, air flow can drive the fan blades to rotate at a high speed; and when the fan blades rotate, all the spoilers are driven to rotate through the rotating shaft, at the moment, metal dust scraps moving at a high speed in the airflow impact the spoilers to be decelerated, and therefore the impact force of the metal dust scraps on a filtering device in the negative pressure pump is greatly reduced, and economic losses caused by damage to the negative pressure pump are avoided.

[0002] CNC machine tools are a type of high-precision, high-efficiency automated mechanical processing equipment. The application of CNC technology has not only brought revolutionary changes to the traditional manufacturing industry, making the manufacturing industry a symbol of industrialization, but also with the continuous development of CNC technology and the expansion of its application fields, it plays an increasingly important role in the development of some important industries related to the national economy and people's livelihood, because the digitization of equipment required for these industries is a major trend in modern development.

[0003] Although the metal dust pollution generated by the CNC machining center during use can be cleaned by vacuuming equipment, the metal dust generated during the machining process of the CNC machining center is heavy and sharp. When the vacuuming equipment is adsorbing, the metal dust will enter the vacuuming equipment at a high speed. The impact force generated can easily damage the filter mechanism in the pump body, thereby causing economic losses. Therefore, in response to the above problems, we propose a new type of CNC machining center that can prevent metal dust pollution. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that the metal dust generated during the machining process of a CNC machining bed is heavy and sharp, and when the dust collection device is adsorbing, the metal dust will enter the dust collection device at a high speed, and the impact force generated is likely to damage the filtering mechanism in the pump body, thereby causing economic losses, and a CNC machining bed that can prevent metal dust pollution is proposed.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, the negative pressure pump is started to form a negative pressure space inside the circular channel, thereby generating suction to draw the metal dust and air in the dust cover into the circular channel and then discharge them through the chip discharge pipe and the hose. During the process, when the air in the dust cover is drawn into the circular channel, the airflow will drive the fan blades to rotate at high speed, and when the fan blades rotate, all the spoilers will be driven to rotate through the rotating shaft. At this time, the metal dust fragments moving at high speed in the airflow will collide with the spoiler and decelerate, thereby greatly reducing the impact force of the metal dust fragments on the internal filtering device of the negative pressure pump and avoiding the economic losses caused by damage to the negative pressure pump.

[0014] 2. In the utility model, when cleaning the sucked-out metal dust and air impurities, the collection box is pulled out from the collection box by holding the handle and pulling the panel, and then ordinary air impurities can be poured out from the opening by tilting, and then the power of the electromagnetic plate is turned off by the controller to make the metal dust debris lose its adsorption force and fall back into the interior of the collection box, and then it can be poured out. This design has the effect of classifying and discharging air impurities and metal dust, and the metal dust debris has the value of being recyclable, thereby achieving the effect of saving resources.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1-Figure 4As shown, the utility model provides a CNC machining bed capable of preventing metal dust pollution, comprising a CNC machine tool 1, first connecting blocks 2 are symmetrically fixedly connected to the outer surfaces of both sides of the CNC machine tool 1 near the bottom, electric push rods 21 are installed on the tops of the two first connecting blocks 2, the tops of the two electric push rods 21 are fixedly connected to the second connecting blocks 22, a dust cover 23 is fixedly connected between the outer surfaces of the two second connecting blocks 22, a dust collecting mechanism 3 is arranged on the top of the dust collecting mechanism 23, a collecting mechanism 4 is arranged on the front side of the CNC machine tool 1, and the dust collecting mechanism 3 includes a circular channel 301, a circular channel 302, and a collecting mechanism 4 is arranged on the front side of the CNC machine tool 1, and the collecting mechanism 3 includes a circular channel 301, a circular channel 303, and a collecting mechanism 4 is arranged on the front side of the CNC machine tool 1, and the collecting mechanism 3 includes a circular channel 301, a circular channel 304, and a collecting mechanism 4 is arranged on the front side of the CNC machine tool 1, and the collecting mechanism 3 includes a circular channel 302, a circular channel 303, and a collecting mechanism 4 is arranged on the front side of the CNC machine tool 1, and the collecting mechanism 3 includes a circular channel 301, a circular channel 304 ... circular channel 305 A mounting piece 303 is fixedly connected between the inner walls of the circular channel 301 near the top, a rotating shaft 305 is rotatably connected between the inner walls of the mounting piece 303 via a bearing, a plurality of spoilers 306 are fixedly connected to the outer surface of the rotating shaft 305 near the bottom at equal intervals, a fan blade 304 is installed on the top of the rotating shaft 305, the circular channel 301 is fixedly connected to the top of the dust cover 23, a negative pressure pump 302 is installed on the top of the circular channel 301, the exhaust port of the negative pressure pump 302 is fixedly connected to a chip removal pipe 307, and the bottom end of the chip removal pipe 307 is fixedly connected to a hose 308.

[0023] The effect achieved by the entire embodiment 1 is that when the CNC machine tool 1 is used to process a metal workpiece, the electric push rods 21 on the first connecting blocks 2 on both sides drive the two second connecting blocks 22 to descend synchronously. At this time, the two second connecting blocks 22 will drive the dust cover 23 to move downward and cover the outside of the CNC machine tool 1. Then, the negative pressure pump 302 is started to form a negative pressure space inside the circular channel 301, thereby generating suction to draw the metal dust and air in the dust cover 23 into the circular channel 301 and then discharge them through the chip removal pipe 307 and the hose 308. During the process, when the air in the dust cover 23 is drawn into the circular channel 301, the airflow will drive the fan blades 304 to rotate at a high speed, and when the fan blades 304 rotate, they will drive all the spoilers 306 to rotate through the rotating shaft 305. At this time, the high-speed moving metal dust debris in the airflow will collide with the spoiler 306 and decelerate, thereby greatly reducing the impact force of the metal dust debris on the internal filtering device of the negative pressure pump 302, avoiding the economic loss caused by damage to the negative pressure pump 302, and the mounting part 303 is mainly used for installing the rotating shaft 305.

[0024] Embodiment 2, as Figure 1-Figure 4As shown, the collecting mechanism 4 includes a collecting box 401, which is fixedly connected to the rear surface of the CNC machine tool 1, and a collecting box 402 is movably arranged inside the collecting box 401, a panel 404 is fixedly connected to the outer surface of one side of the collecting box 402, a handle 406 is fixedly connected to the outer surface of one side of the panel 404, a controller 405 is installed near the corner of the outer surface of one side of the panel 404, two groups of electromagnetic plates 403 are arranged between the inner walls of the collecting box 402, an opening 407 is opened near the bottom on the outer surface of the other side of the collecting box 402, and the bottom end of the hose 308 is fixedly connected to the top of the collecting box 401.

[0025] The effect achieved by the entire embodiment 2 is that when the air containing metal dust is discharged through the hose 308, it will enter the collection box 401 and fall into the collection box 402. The metal dust and debris in the air will be adsorbed by the electromagnetic plate 403 above the inside of the collection box 402 during the falling process, and ordinary air impurities will fall to the inner bottom of the collection box 402. When cleaning, the collection box 402 can be pulled out of the collection box 401 by holding the handle 406 and pulling the panel 404. After that, the ordinary air impurities can be poured out from the opening 407 by tilting, and then the power of the electromagnetic plate 403 can be turned off by the controller 405, so that the metal dust and debris will lose their adsorption force and fall back into the interior of the collection box 402, and then they can be poured out. This design has the effect of classifying and discharging air impurities and metal dust, and the metal dust and debris have recycling value, thereby saving resources.

[0026] Working principle: When the CNC machine tool 1 is used to process a metal workpiece, the electric push rods 21 on the first connecting blocks 2 on both sides drive the two second connecting blocks 22 to descend synchronously. At this time, the two second connecting blocks 22 will drive the dust cover 23 to move downward and cover the outside of the CNC machine tool 1. Then, the negative pressure pump 302 is started to form a negative pressure space inside the circular channel 301, thereby generating suction to draw the metal dust and air in the dust cover 23 into the circular channel 301 and then discharge them through the chip discharge pipe 307 and the hose 308. During the process, when the air in the dust cover 23 is drawn into the circular channel 301, the airflow will drive the fan blades 304 to rotate at a high speed, and when the fan blades 304 rotate, they will drive all the spoilers 306 to rotate through the rotating shaft 305. At this time, the high-speed moving metal dust debris in the airflow will collide with the spoiler 306 to decelerate, thereby greatly reducing the metal dust debris on the internal filtering device of the negative pressure pump 302 The impact force avoids the economic loss caused by damage to the negative pressure pump 302. When the air containing metal dust is discharged through the hose 308, it will enter the collection box 401 and fall into the collection box 402. The metal dust and debris in the air will be adsorbed by the electromagnetic plate 403 above the inside of the collection box 402 during the falling process, and ordinary air impurities will fall to the inner bottom of the collection box 402. When cleaning, hold the handle 406 and pull the panel 404 to pull the collection box 402 out of the collection box 401, and then pour out the ordinary air impurities from the opening 407 by tilting, and then turn off the power of the electromagnetic plate 403 through the controller 405 to make the metal dust and debris lose the adsorption force and fall back into the interior of the collection box 402, and then pour it out. This design has the effect of classifying and discharging air impurities and metal dust, and the metal dust and debris have recycling value, thereby saving resources.
