[0002] Mechanical parts are various basic elements and components that make up mechanical equipment, and are the basic units used in the field of mechanical engineering for manufacturing, assembling, and maintaining mechanical equipment. In order to adapt to the processing of complex parts and high-precision processing, numerical control grinding machines are usually used for processing. It precisely controls the movement of each coordinate axis of the machine tool through a numerical control system to achieve high-precision grinding of workpieces. It can automatically complete the grinding process of workpieces according to the pre-written processing program, and at the same time can prevent debris from splashing, which is not only convenient for cleaning but also can prevent debris from entering the moving parts of the machine tool, reducing the friction between parts so as not to affect the processing accuracy.

[0003] In actual scenarios, the methods of using guardrails and protective covers are mostly adopted to block the debris generated during grinding. The guardrails and protective covers usually enclose the processing area, reducing the space where the operator can move, restricting the operator when loading workpieces, adjusting tools, and performing equipment maintenance operations. For some complex processing equipment or machinery with multiple moving parts, it may be difficult for guardrails and protective covers to completely cover all areas where danger may occur, resulting in protection blind spots and unable to achieve the purpose of preventing debris well.

Electromagnetic blocks are embedded at the lower ends of the two Z-shaped plates.

[0008] Preferably, the two electromagnetic blocks are respectively located directly above the two permanent magnetic blocks, and the electromagnetic blocks have the same magnetic property as the permanent magnetic blocks.

[0009] Preferably, the debris cleaning mechanism includes a rectangular bottom plate fixed to the bottom wall of the main body of the CNC machine tool. The middle of the upper end of the rectangular bottom plate is fixed with a fixed base. An electromagnetic fixing plate is embedded in the middle of the upper end of the fixed base. A debris blocking frame one is fixed to the upper end of the rectangular bottom plate. Inside the debris blocking frame one, there is a debris blocking frame two fixed to the upper end of the rectangular bottom plate.

[0010] Preferably, inclined surfaces are provided at the mutually approaching ends of the fixed base and the debris blocking frame two, and inclined surfaces are also provided at the mutually approaching ends of the debris blocking frame one and the debris blocking frame two.

Detailed Implementation Manner

[0018] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] Embodiment: Refer to Figures 1 to 8 , a CNC grinding machine for preventing debris of mechanical parts, comprising: a main body 1 of a CNC machine tool, a grinding tool rest 2 is provided on the upper side of the inner cavity of the main body 1 of the CNC machine tool, an air curtain protection mechanism 3 is provided on the upper top wall of the main body 1 of the CNC machine tool, and a debris cleaning mechanism 4 is provided on the bottom wall of the main body 1 of the CNC machine tool. A plurality of tools are provided in the grinding tool rest 2. By switching between different tools, the parts placed in the device can be polished, cut or even drilled. The components in the grinding tool rest 2 can draw external air into the device and form two air curtains inside the main body 1 of the CNC machine tool. And a photoelectric sensor is provided between the two air curtains. When the inner air curtain fails to block the flying debris, the photoelectric sensor therein can accurately detect and activate the outer air curtain to form two air curtains to block the flying debris, and at the same time, the air flow rate and air volume in the air curtain will also be increased to ensure the protection effect of the device; The air curtain will blow the debris generated during processing to the debris cleaning mechanism 4 located on the lower side. The components in the debris cleaning mechanism 4 can separate the debris from the cutting fluid. While transporting the debris out of the device, the cutting fluid therein can also be transported to the cutting fluid tank of the main body 1 of the CNC machine tool itself.

[0021] Further explanation is as follows. In order to form an air curtain around the workbench, the following settings are made. As shown in the figure, the air curtain protection mechanism 3 includes an air curtain frame 1 31 fixed to the upper top wall of the CNC machine tool main body 1. An air curtain frame 2 32 fixed to the upper top wall of the CNC machine tool main body 1 is arranged inside the air curtain frame 1 31. Rectangular grooves are formed at the upper ends of both the air curtain frame 1 31 and the air curtain frame 2 32. The air curtain frame 1 31 and the air curtain frame 2 32 are communicated with each other. Air outlet grooves 33 are formed at the bottom walls of the rectangular grooves. Wind shielding plates 34 are slidably connected to the inner walls of both the air curtain frame 1 31 and the air curtain frame 2 32. In the initial state of the device, the air outlet grooves 33 are in contact with the wind shielding plates 34. An air inlet assembly 35 is arranged between the two wind shielding plates 34. Permanent magnetic blocks 36 are embedded at the upper ends of the two wind shielding plates 34.

[0022] Still further explanation is as follows. In order to control the number of formed air curtains, the following settings are made. As shown in the figure, the air inlet assembly 35 includes a U-shaped pipe 351 fixed to the upper top wall of the CNC machine tool main body 1. An electric telescopic rod 352 is fixed inside the U-shaped pipe 351. A conical stopper 353 is fixed to the telescopic end of the electric telescopic rod 352. An inner conical ring 354 fixed to the inner wall of the U-shaped pipe 351 is arranged above the conical stopper 353. Air inlet grooves 355 are arrayed on the outer surface of one end of the U-shaped pipe 351. The other end of the U-shaped pipe 351 is communicated with an air extraction pump. A piston rod 356 is hermetically and slidably connected inside the U-shaped pipe 351. An activity top cover 357 is fixed to the upper end of the piston rod 356. The activity top cover 357 is slidably connected to the outer surface of the U-shaped pipe 351. Z-shaped plates 358 are symmetrically fixed to the lower end of the activity top cover 357. Electromagnetic blocks 359 are embedded at the lower ends of the two Z-shaped plates 358. The two electromagnetic blocks 359 are respectively located directly above the two permanent magnetic blocks 36. The electromagnetic blocks 359 have the same magnetism as the permanent magnetic blocks 36; Specifically, start the air pump fixedly connected to one end of the U-shaped tube 351 and the electric telescopic rod 352. The electric telescopic rod 352 will shorten and drive the conical stopper 353 fixedly connected to it to move downward. The air pump will extract external air into the U-shaped tube 351 through the liquid outlet pipe 477. The air flowing into the U-shaped tube 351 will flow upward through the inner wall of the U-shaped tube 351 and the gap between the conical stopper 353 and the inner conical ring 354. The air will push the piston rod 356 located in the U-shaped tube 351 to move upward, and the movable top cover 357 and the Z-shaped plate 358 fixedly connected to it will move upward simultaneously until the movable top cover 357 moves to the middle of the air inlet groove 355. The Z-shaped plate 358 will also drive the electromagnetic block 359 to move upward. At this time, the electromagnetic block 359 located in the rectangular groove on the second air curtain frame 32 is energized. Under the magnetic action, the permanent magnet block 36 will drive the wind baffle 34 located in the rectangular groove on the second air curtain frame 32 to move upward, so that the piston rod 356, the U-shaped tube 351, the wind baffle 34, and the air outlet groove 33 all change from the airtight sealing state to the airtight communication state. The air in the U-shaped tube 351 will flow into the CNC machine tool main body 1 through the air outlet groove 33 opened on the bottom wall of the rectangular groove. The flowing air will form an airtight air curtain around the fixed base 42.

[0023] Furthermore, for collecting the splashed debris, the following settings are made. As shown in the figure, the debris cleaning mechanism 4 includes a rectangular bottom plate 41 fixed to the bottom wall of the CNC machine tool main body 1. The middle of the upper end of the rectangular bottom plate 41 is fixedly provided with a fixed base 42. The middle of the upper end of the fixed base 42 is embedded with an electromagnetic fixing plate 43. The upper end of the rectangular bottom plate 41 is fixedly provided with a debris blocking frame one 44. A debris blocking frame two 45 fixed to the upper end of the rectangular bottom plate 41 is arranged inside the debris blocking frame one 44. Oblique surfaces are provided at one ends of the fixed base 42 and the debris blocking frame two 45 close to each other, and oblique surfaces are also provided at one ends of the debris blocking frame one 44 and the debris blocking frame two 45 close to each other. A plurality of discharge grooves 46 are arranged in an array at the upper end of the rectangular bottom plate 41. The discharge grooves 46 are located between the debris blocking frame one 44 and the debris blocking frame two 45 and between the fixed base 42 and the debris blocking frame two 45. A transportation component 47 is arranged below the rectangular bottom plate 41.

[0024] To further illustrate, the following settings are made to separate and transport the chips and the cutting fluid. As shown in the figure, the transport assembly 47 includes two inclined baffles 471 fixed to the top wall of the rectangular bottom plate 41. The lower ends of the two inclined baffles 471 are fixed with a sealed housing 472. An endless chain conveyor 473 is provided on the upper side of the inner cavity of the sealed housing 472. One end of the sealed housing 472 and the endless chain conveyor 473 penetrates outside the main body 1 of the CNC machine tool. The bottom wall of the inclined baffle 471 is fixed with an elliptical bottom plate 474. Two sealing plates 475 are fixed to the bottom wall of the elliptical bottom plate 474. The two sealing plates 475 and the inner arc wall of the elliptical bottom plate 474 form a cutting fluid collection chamber. A liquid outlet groove 476 is opened in the cutting fluid collection chamber. One end of the sealed housing 472 is fixed with a liquid outlet pipe 477 communicating with the cutting fluid collection chamber; Specifically, the chips blocked by the air curtain will fall between the air curtain frame two 32 and the air inlet assembly 35, and then slide downward through the opened discharge chute 46 and the inclined baffle 471 until they slide to the upper end of the endless chain conveyor 473. The cutting fluid sprayed during processing will also flow to the upper end of the endless chain conveyor 473, and then flow downward along the gaps of the endless chain conveyor 473 into the cutting fluid collection chamber. The chips located at the upper end of the endless chain conveyor 473 will be transported outside the main body 1 of the CNC machine tool along with the endless chain conveyor 473 and the port of the sealed housing 472, and collected by the chip box. The cutting fluid that enters the cutting fluid collection chamber will flow along the liquid outlet groove 476 and the liquid outlet pipe 477 into the cutting fluid tank of the main body 1 of the CNC machine tool itself.

[0025] The working principle of the present invention is as follows: Place the parts to be processed on the fixed base 42, then start the electromagnetic fixing plate 43 so that it can magnetically adsorb the parts above the fixed base 42. Then start the program in the main body 1 of the numerical control machine tool. Through the switching and rotation movement of the cutting tools in the chip cleaning mechanism 4, the parts placed on the fixed base 42 can be processed and formed. During the grinding process of the cutting tools, the cutting tools interact with the workpiece, and the material is removed by means of extrusion, shearing, etc., causing the processed material to undergo plastic deformation and fracture, thus generating chips. While using the chip cleaning mechanism 4 to process the parts, start the air extraction pump fixedly connected to one end of the U-shaped tube 351 and the electric telescopic rod 352. The electric telescopic rod 352 will shorten and drive the conical stopper 353 fixedly connected to it to move downward. The air extraction pump will extract the external air into the U-shaped tube 351 through the liquid outlet pipe 477. The air flowing into the U-shaped tube 351 will flow upward through the inner wall of the U-shaped tube 351 and the gap between the conical stopper 353 and the inner conical ring 354. Under the impact force of the air flow, the air will push the piston rod 356 located in the U-shaped tube 351 to move upward, and the movable top cover 357 and the Z-shaped plate 358 fixedly connected to it will move upward simultaneously until the movable top cover 357 moves to the middle of the air inlet groove 355. At this time, the air in the U-shaped tube 351 can enter the two rectangular grooves through the air inlet groove 355. The Z-shaped plate 358 therein will also drive the electromagnetic block 359 to move upward. At this time, energize the electromagnetic block 359 located in the rectangular groove on the second air curtain frame 32 to make it magnetic. Since the magnetic properties of the electromagnetic block 359 and the permanent magnet block 36 are the same, under the magnetic action, the permanent magnet block 36 will drive the wind shield 34 located in the rectangular groove on the second air curtain frame 32 to move upward; At this time, the piston rod 356, the U-shaped tube 351, the windshield 34, and the air outlet groove 33 all change from the airtight sealing state to the airtight connection state. The air in the U-shaped tube 351 enters the rectangular groove through the air inlet groove 355 and will flow into the main body 1 of the CNC machine tool through the air outlet groove 33 opened on the bottom wall of the rectangular groove. The air outlet groove 33 at the lower end of the second air curtain frame 32 is directly above the second debris baffle 45. The flowing air will form an airtight air curtain around the fixed base 42. The flying debris generated during the processing of parts by the debris cleaning mechanism 4 will be blocked by the air curtain (this air curtain is like an invisible wall that can form a physical barrier on the path of the flying debris. When the debris encounters the air curtain, it will be affected by the resistance of the air flow, changing its flying direction or speed, thereby reducing the possibility of the debris flying outwards. Moreover, the generated air flow can also produce a certain adsorption effect. The rapidly flowing air will form a low-pressure area around it. According to Bernoulli's principle, the low-pressure area will generate an adsorption force on the surrounding debris, making it easier for the debris to be captured by the air flow and restricted within a certain range. Even if some debris has a high initial velocity, under the adsorption effect of the air curtain, it will be guided into the air flow and flow with the air flow without splashing randomly); The debris blocked by the air curtain will fall between the second air curtain frame 32 and the air inlet assembly 35, and then slide down through the opened discharge chute 46 and the inclined baffle 471 until it slides to the upper end of the plate chain conveyor 473. The cutting fluid sprayed during processing will also flow to the upper end of the plate chain conveyor 473 and then flow down along the gaps of the plate chain conveyor 473 into the cutting fluid collection chamber. The debris located at the upper end of the plate chain conveyor 473 will be transported to the outside of the main body 1 of the CNC machine tool along with the plate chain conveyor 473 and the port of the sealed housing 472 and collected through the debris box. The cutting fluid that enters the cutting fluid collection chamber will flow along the liquid outlet chute 476 and the liquid outlet pipe 477 to the cutting fluid tank of the main body 1 of the CNC machine tool itself. The cutting fluid in the main body 1 of the CNC machine tool can be recycled. The air extraction pump for extracting external air is connected to the liquid outlet pipe 477, and multiple open slots are provided on the outer surface of the pipe connected to the liquid outlet pipe 477, which can drive the cutting fluid in the cutting fluid collection chamber to flow into the liquid outlet pipe 477 by the suction force of extracting air. Moreover, since the U-shaped tube 351 is located directly above and the connection part is not in a sealed state, the air extraction pump will not extract the cutting fluid into the U-shaped tube 351, so that the remaining small amount of cutting fluid will not stay in the cutting fluid collection chamber; When the debris is relatively large in size and has a relatively high initial velocity, and the air curtain around it fails to block it, the debris will splash inside the main body 1 of the CNC machine tool. The photoelectric sensor located inside the main body 1 of the CNC machine tool can detect whether the debris breaks through the air curtain (the photoelectric sensor consists of a transmitter and a receiver. The light emitted by the transmitter directly shines on the receiver. When the air curtain is working properly and no debris breaks through, the light emitted by the transmitter can be stably received by the receiver. At this time, the photoelectric sensor is in a normal working state and outputs a stable electrical signal. When debris breaks through the air curtain and enters the optical path between the transmitter and the receiver, the debris will block part or all of the light, resulting in a decrease or disappearance of the light intensity received by the receiver, thereby detecting whether the air curtain can block the splashing debris), increasing the magnitude of the current flowing into the electric telescopic rod 352, causing it to drive the conical block 353 to move downward by a greater distance, increasing the gap between the conical block 353 and the inner conical ring 354, allowing more air to enter the rectangular groove at the same time, or by increasing the power of the air extraction pump, increasing the air flow velocity and flow rate of the air curtain; At the same time, it is also necessary to energize the electromagnet 359 in the rectangular groove on the air curtain frame 1, making it magnetic as well, and then attracting the permanent magnet 36 located directly below it, causing the permanent magnet 36 to drive the windshield 34 to move upward simultaneously. Then, an outer air curtain is formed around the inner air curtain by the air entering the rectangular groove, blocking the splashing debris through the two air curtains to ensure the normal operation of the device (when activating the second air curtain, it is necessary to increase the power of the air extraction pump or adjust the position of the conical block 353 so that more air can enter the rectangular groove. Without affecting the protection function of the first air curtain, the second air curtain blocks the debris that is still splashing after being decelerated by the first air curtain), or the number of air curtains to be turned on can also be selected according to the use of different tools in the grinding tool rest 2. When the grinding tool rest 2 in the device cuts parts with a milling cutter, the debris generated by the machining at this time is relatively large in size and has a relatively high initial velocity. Two air curtains can be directly energized to form to block the splashing debris. When the grinding tool rest 2 grinds parts with a grinding head, only one air curtain is required for processing. It is switched through the numerical control program, and has good linkage processing during machining, ensuring that the device can be processed well.
