The utility model utilizes a synchronous drive component connected to the output shaft end of the machine tool main control motor, and after a series of mechanical transmissions, the debris that falls between two adjacent cleaning partitions can fall to the top of the waste chip discharge guide plate as the cleaning roller rotates, so that the debris that falls on the waste chip discharge guide plate is uniformly discharged and collected through the right side of the CNC machine tool body through oscillation. The entire cleaning process is synchronized with the rotation of the machine tool main control motor during the processing of the CNC machine tool body.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The present invention will be further described below in conjunction with the embodiments.

[0022] Reference Figures 1 to 10 A CNC machine tool with an automatic chip cleaning function includes a machine tool base 1, the machine tool base 1 includes a fixed seat for fixing parts and a movable seat for fixing a tool head, a limiting component 2 and a chip receiving box 3 are installed on the machine tool base 1, and the limiting component 2 is installed on one side of the fixed seat to limit the range of chip scattering; The limiting component 2 includes an airflow guide frame 201 and an air guide pipe 206. The air guide pipe 206 is fixedly installed on the airflow guide frame 201 and is connected to an external air source. A plurality of downward blowing nozzles 202 are embedded and fixedly installed in the airflow guide frame 201. The ends of the downward blowing nozzles 202 are distributed downward. A plurality of rotating nozzles 203 are embedded and rotatably connected to the airflow guide frame 201. The plurality of rotating nozzles 203 are opposite to each other and correspond to each other one by one. A rotating blade 204 is fixedly connected to the rotating nozzle 203. When the airflow passes through the rotating blade 204, the rotating blade 204 and the rotating nozzle 203 are driven to rotate. The waste chip receiving box 3 comprises a box body 301 slidably mounted on the machine tool base 1 , and the box body 301 is used for receiving the fallen waste chips.

[0023] Specifically, both side plates of the airflow guide frame 201 are embedded with blocking capsules 205 fixedly installed therein. When the air pressure in the airflow guide frame 201 is transmitted to the blocking capsules 205 , the blocking capsules 205 will expand.

[0024] During the operation of the CNC machine tool, waste chips will continuously fly out on the parts. During the processing, it is necessary to move the position of the airflow guide frame 201 close to the position of the processed parts, and place the down-blowing nozzle 202 just above the part processing position. The air guide pipe 206 will pass the external air source into the airflow guide frame 201. As the CNC machine tool is processing, the airflow in the air guide pipe 206 will pass through the down-blowing nozzle 202 and the rotating nozzle 203 on the airflow guide frame 201. The airflow generated by the down-blowing nozzle 202 can blow the waste chips generated by the parts downward above the part processing position, so that the waste chips fall into the box body 301. At the same time, under the action of the airflow, the rotating fan blade 204 will rotate, driving the rotating nozzle 203 to rotate. Since the air outlet of the rotating nozzle 203 does not coincide with the rotation center of the rotating nozzle 203, the airflow from the rotating nozzle 203 during the rotation of the rotating nozzle 203 The air outlet nozzle 03 blows around at a certain angle, so that when the waste chips hit other parts of the machine tool and splash during the falling process, they will also be blown to the bottom of the downward blowing nozzle 202 by the airflow of the rotating nozzle 203 until the waste chips fall into the box body 301. Therefore, during the processing, the waste chips will be continuously restricted by the airflow, and the force generated by the accelerated airflow in the downward blowing nozzle 202 is mainly used to guide the waste chips into the box body 301, collect the fallen waste chips, limit the range of waste chip scattering, and facilitate cleaning. At the same time, under the action of air pressure, the blocking capsule 205 expands to both sides of the airflow guide frame 201, forming a barrier to prevent waste chips from splashing, and can limit the airflow ejected from the downward blowing nozzle 202 and the rotating nozzle 203, so that the airflow quickly forms a stable state in a smaller space, so as to ensure that the airflow can quickly play a stable limiting role on the waste chips.

[0025] Specifically, the box body 301 is fixedly connected with the air injection pipe 207 and the collecting pipe 208 , and both ends of the air flow guide frame 201 extend downward and are fixedly connected with the air injection pipe 207 and the collecting pipe 208 .

[0026] Specifically, the air outlet of the air jet pipe 207 faces the collecting pipe 208 , and a slot for waste chips to enter is provided on one side of the collecting pipe 208 .

[0027] Specifically, one end of the collecting pipe 208 is fixedly connected to a conduit 209 , and the conduit 209 extends to the outside of the machine tool base 1 .

[0028] When the airflow in the airflow guide frame 201 passes through the laterally distributed jet pipe 207, the airflow covers the entire width direction of the box body 301 and flows toward the collecting pipe 208. When the airflow in the airflow guide frame 201 passes through the longitudinally distributed collecting pipe 208, the airflow will generate negative pressure on one side of the slot of the collecting pipe 208, that is, the pressure is smaller where the flow rate is faster. The airflow blown out from the jet pipe 207 will blow the waste chips falling on the box body 301 toward the collecting pipe 208, and will be sucked into the collecting pipe 208 by the negative pressure near the collecting pipe 208. Under the action of the airflow, it is blown from the collecting pipe 208 to the duct 209 until the waste chips are blown out, thereby preventing excessive waste chips from accumulating in the box body 301. At the same time, the waste chips will be transferred to the outside of the machine tool base 1 for unified collection.

[0029] Specifically, an iron attraction plate 216 is embedded and fixedly installed in the bottom plate of the collecting pipe 208 , and a rotating plate 212 is rotatably connected to the side plate of the collecting pipe 208 , and the rotating plate 212 is located above the iron attraction plate 216 .

[0030] Specifically, the collecting tube 208 is rotatably connected to a magnetic baffle 211 near the slot, and an electromagnet 210 is embedded and fixedly installed in the top plate of the collecting tube 208 . The electromagnet 210 can generate a magnetic force on the magnetic baffle 211 .

[0031] Specifically, the magnetic baffle 211 and the rotating plate 212 are rotatably connected with a rotating connecting rod 213. The rotating axis of the rotating plate 212 on the collecting tube 208 is distributed on the side away from the rotating connecting rod 213. One side of the rotating plate 212 is rotatably connected with a waste chip guide plate 214 through a torsion spring. The waste chip guide plate 214 is embedded with and fixedly connected with a reset magnet 215 that generates magnetic attraction to the iron attraction plate 216.

[0032] When the airflow enters the collecting tube 208 from the end of the airflow guide frame 201, the magnetic baffle 211 is inclined, so that the diameter of the tube through which the airflow passes is reduced, thereby accelerating the flow rate of the airflow and improving the effect of the negative pressure. At the same time, the electromagnet 210 changes the magnetic pole at a certain frequency, that is, 60Hz or other frequencies are installed to change the magnetic pole generated by the electromagnet 210. Then, the magnetic baffle 211 is subjected to the magnetic force of the electromagnet 210 and changes according to this frequency. The magnetic baffle 211 will reciprocate in the collecting tube 208, constantly changing the diameter of the tube through which the airflow passes, that is, the airflow velocity will constantly change regularly, so that the airflow in the collecting tube 208 continues to change, and the waste chips entering the collecting tube 208 will continue to be impacted by the changing airflow, blowing away the waste chips gathered together to prevent the waste chips from gathering. At the same time, as the magnetic baffle 211 is subjected to the magnetic attraction of the electromagnet 210 and rotates upward When the rotating plate 212 is in motion, by rotating the connection between the connecting rod 213 and the magnetic baffle 211, the rotating plate 212 will also move upward with the magnetic baffle 211. The upward moving rotating plate 212 will cause the waste chips sucked into the collection pipe 208 to shake upward, and under the action of the airflow, the waste chips in the air will be blown away and blown toward the conduit 209, making it difficult for the waste chips to gather when entering the collection pipe 208, thereby avoiding the waste chips from gathering and clogging in the collection pipe 208. At the same time, when the rotating plate 212 moves upward, the reset magnet 215 on the waste chip guide plate 214 releases the magnetic adsorption of the iron attraction plate 216, and under the action of the torsion spring, the waste chip guide plate 214 quickly flips upward on the rotating plate 212, and quickly pushes the waste chips on the waste chip guide plate 214 onto the rotating plate 212, preventing the waste chips from falling from the waste chip guide plate 214 during the upward movement of the rotating plate 212. When the rotating plate 212 returns to the lowest point, the reset magnet 215 is re-adsorbed on the iron attraction plate 216.

[0033] Specifically, a turntable 217 is rotatably inserted into the side plate of the airflow guide frame 201, and a winding frame 218 is fixedly connected to one side of the turntable 217. A rotating baffle 219 is fixedly connected to one side of the turntable 217 through a cylinder. The rotating baffle 219 is located in the airflow guide frame 201. Under the action of the airflow, the rotating baffle 219 rotates and drives the winding frame 218 to rotate through the turntable 217. A material receiving box 220 is fixedly connected to the position corresponding to the winding frame 218 on the airflow guide frame 201, and electric push rods are rotatably connected to both side plates of the material receiving box 220. 222, the output end of the electric push rod 222 is fixedly connected with a hollow splint 221, and the two side plates of the material receiving box 220 are fixedly connected with a coolant box 223. A piston plate 225 is slidably connected in the coolant box 223, and a connecting pipe 224 is fixedly connected to one side of the piston plate 225. One end of the connecting pipe 224 passes through and is fixedly installed on the side plate of the hollow splint 221, and the end of the connecting pipe 224 close to the piston plate 225 passes through and is fixedly connected with a pressure valve 226. A nozzle is embedded and fixedly installed on the side of the hollow splint 221 facing the winding frame 218.

[0034] Under the action of the airflow in the airflow guide frame 201, the rotating baffle 219 rotates, and the winding frame 218 is driven to rotate through the turntable 217. The long strips of waste generated during the processing of the parts will contact the winding frame 218, and as the winding frame 218 rotates, the long strips of waste will be wound around the winding frame 218, preventing the long strips of waste from falling into the box body 301, resulting in the remaining waste chips being unable to enter the collection tube 208.

[0035] At the same time, during the rotation process, the winding rack 218 continuously winds the long strips of waste falling from the parts. When there is a lot of waste wound on the winding rack 218 and it needs to be cleaned up, the electric push rod 222 is started to quickly push the hollow clamping plate 221 toward the winding rack 218, and the two hollow clamping plates 221 are moved toward the winding rack 218 to quickly clamp the waste wound on the winding rack 218. When the waste is turned off by the cutter head, the temperature is high and it is brittle. When the two hollow clamping plates 221 quickly move toward the winding rack 218, the high-temperature waste will be quickly crushed and fall into the receiving box 220, and the waste chips can be removed from the receiving box 220. 20 falls into the box body 301, thereby realizing the cleaning of the long waste on the winding frame 218, and at the same time, the hollow clamping plate 221 moves toward the winding frame 218, which will drive the piston plate 225 to slide in the coolant box 223, and the pressure of the coolant in the coolant box 223 gradually increases in the piston plate 225 and the coolant box 223. When the pressure is greater than the pressure valve 226, the coolant will quickly pass through the connecting pipe 224 into the nozzle in the hollow clamping plate 221, and quickly cool down the crushed waste chips, so as to avoid the waste chips showing a certain magnetism under high temperature and being adsorbed to other components, so as to facilitate the collection of long waste.

[0036] It should be noted that only a small amount of coolant needs to be filled in the coolant box 223, so that the coolant can be sprayed only after the hollow clamping plate 221 crushes the long strip of waste.

[0037] Specifically, the waste chip receiving box 3 includes a plurality of chip guide plates 302 that are fixedly installed between the two side plates of the box body 301 and a plurality of rotating dial heads 303 that are rotatably connected to the bottom plate of the box body 301 and can rotate under the action of airflow.

[0038] The waste chips will fall on the chip guide plate 302 under the action of the airflow, and slide into the box body 301 along the inclined surface of the chip guide plate 302, preventing the waste chips from flying out of the box body 301 from the inclined surface under the action of the airflow ejected from the air jet pipe 207. At the same time, when the airflow acts on the rotating dial head 303, the rotating dial head 303 will rotate on the box body 301 and scatter the waste chips, preventing the waste chips from gathering and causing the friction between the waste chips and the box body 301 to be too large and unable to enter the box body 301. It can also prevent the gathered waste chips from entering the collecting tube 208 and causing the waste chips to accumulate in the collecting tube 208.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
