When the CNC machine tool body 100 processes the workpiece, if the machining drill bit 109 generates debris, smoke and a large amount of heat, the uniform dust collection and cleaning mechanism will collect the dust at the processing area and simultaneously discharge the heat and smoke generated, facilitating dust collection and heat dissipation.

[0027] In order to facilitate the installation of the retaining ring 1041 and the vacuum head 1047 for vacuuming by means of the installation component, in this embodiment, preferably, the installation component includes a retaining ring 1041 that fits onto the outer surface of the mounting base 104. The upper surface edge of the retaining ring 1041 is provided with a mounting bolt 1045. The outer surface of the mounting base 104 is provided with an internal threaded hole that matches the mounting bolt 1045. After the retaining ring 1041 is fitted, the mounting bolt 1045 can be rotated to fit into the internal threaded hole to fix the retaining ring 1041 in place.

[0028] To facilitate uniform dust collection and heat dissipation at the processing area using a uniform dust collection component, in this embodiment, preferably, the uniform dust collection component includes an annular negative pressure channel 1040 integrally formed inside a fixing ring 1041.

A bellows 1044 is sealed and installed on one side of the fixing ring 1041. When a negative pressure is generated inside the annular negative pressure channel 1040, all four dust collection heads 1047 will generate negative pressure for uniform dust collection, resulting in cleaner dust collection and facilitating the absorption of heat and fumes generated during processing.

[0029] To facilitate the centralized collection of debris after dust extraction using the collection assembly, in this embodiment, preferably, the collection assembly includes a mounting plate 1042 welded and fixed to one end of the base 101. A collection box 1043 is fixedly mounted on the surface of the mounting plate 1042 at the end of the housing 102 using fixing bolts.

One end of the limiting connection port 1023 has an internal threaded mounting hole that matches the locking bolt. The door panel 1021 can be sealed and installed inside the limiting connection port 1023 by the sealing ring 1022 and fixed by the locking bolt. After fixing, the inside of the collection box 1043 is sealed and negative pressure is generated. After dust is sucked in, the debris enters the inside of the collection box 1043 for collection.

[0030] To facilitate negative pressure suction and cleaning of the interior of the collection box 1043, the corrugated pipe 1044, and the annular negative pressure channel 1040 using a negative pressure assembly, in this embodiment, preferably, the negative pressure assembly includes a negative pressure fan 1048 fixedly mounted on the upper surface of the collection box 1043 by fixing bolts, and the negative pressure fan 1048 is electrically connected to the controller 108 via a wire. The surface of the negative pressure fan 1048 extends into the interior of the collection box 1043 and is sealed with a negative pressure connecting pipe 10. 49. The end of the negative pressure connecting pipe 1049 is located inside the top of the collection box 1043 and is fixed with a dustproof net 1046 by screws. When the negative pressure fan 1048 is working, it can generate negative pressure inside the collection box 1043, the corrugated pipe 1044 and the annular negative pressure channel 1040, which facilitates negative pressure dust collection. When the negative pressure is generated, the dustproof net 1046 prevents dust from entering the end of the negative pressure connecting pipe 1049 during dust collection, making it difficult for debris to enter the interior of the negative pressure fan 1048.

[0031] The convenient unloading mechanism includes a convenient unloading component located at the bottom of the collection assembly. After the collection box 1043 is filled with debris after dust collection, the door panel 1021 can be opened, and the convenient unloading mechanism can unload the debris that has filled the collection box 1043.

[0032] To facilitate the discharge of debris accumulated inside the collection bin 1043 via a convenient unloading assembly, in this embodiment, preferably, the convenient unloading assembly includes a main feeding ramp structure 1025 fixedly installed on one side of the bottom inside the collection bin 1043 by screws. An auxiliary feeding ramp 1024 is fixedly installed on one side of the main feeding ramp structure 1025 at the bottom inside the collection bin 1043 by screws. During unloading, after the door panel 1021 is opened, the main feeding ramp structure 1025 feeds the material from the bottom inside to the surface of the main feeding ramp structure 1025, and then discharges it to the outside through the limiting connection port 1023. Any material not discharged from the surface of the main feeding ramp structure 1025 can be easily cleaned and unloaded using cleaning tools.

[0033] The negative pressure fan 1048 in this utility model is model number 912.

[0034] The working principle and usage process of this utility model: When using this CNC machine tool with a workpiece clamping structure, the bottom end of the base 101 contacts the ground to stably place the main body 100 of the CNC machine tool at the usage position. After the main body 100 of the CNC machine tool is stably placed, the workpiece to be processed is placed on the surface of the operating base plate 105. The auxiliary electric cylinder moves to drive the workpiece clamping plate 107 to clamp it. Then, the protective door 106 is slid closed on the surface of the machine box 102. The main cylinder drives the mounting base 104 to move down, and the servo motor drives the drill bit 109 to move down to contact the surface of the workpiece for processing.

[0035] Before use, the door panel 1021 is sealed and closed inside the limiting connection port 1023 by the sealing ring 1022 and fixed by the locking bolts. When the CNC machine tool body 100 generates chips during processing, the negative pressure fan 1048 is powered on and generates negative pressure inside the collection box 1043 through the negative pressure connecting pipe 1049. Then, negative pressure is generated inside the annular negative pressure channel 1040 through the corrugated pipe 1044. When negative pressure is generated inside the annular negative pressure channel 1040, the dust is collected by the dust suction head 1047 corresponding to the processing area of ​​the drill bit 109. Simultaneously, it absorbs the smoke and heat generated, and the absorbed debris is then collected inside the collection box 1043 through the annular negative pressure channel 1040 and the corrugated pipe 1044. At the same time, the dustproof net 1046 protects the end of the negative pressure connecting pipe 1049 from entering the interior of the negative pressure fan 1048, and facilitates uniform dust suction and material collection. During processing, it is not easy to cause debris accumulation that affects the processing operation. At the same time, it is convenient to absorb heat and smoke for heat dissipation, improving the convenience of debris cleaning and heat dissipation of the CNC machine tool body 100 during workpiece processing.

[0036] Finally, when the inside of the collection box 1043 is full, the reverse operation is performed to place a trash can at the bottom of the front surface of the limiting connection port 1023, or a recycling box if the debris can be recycled. After placement, the door panel 1021 is opened from inside the limiting connection port 1023, and the material is guided to the surface of the bottom main guiding inclined structure 1025 through the auxiliary guiding inclined surface 1024. The material is then guided to the outside through the main guiding inclined structure 1025 again. For any debris that is not completely discharged from the surface of the main guiding inclined structure 1025, it is convenient to clean it with tools. This is more convenient than directly cleaning the bottom of the inside of the collection box 1043, improving the convenience of unloading debris after it is collected inside the collection box 1043 of the CNC machine tool body 100 during workpiece processing.

[0037] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
