Therefore, they should not be construed as limiting the present invention. Furthermore, in the description of the present invention, "several" means two or more, unless otherwise specifically defined.

[0042] See also Figures 1-12 As shown, the present invention provides a magnetic chip suction device for a vertical machining center worktable, including a housing and a control panel 100 arranged in front of the housing. A longitudinal feed system 110 and a transverse feed system 120 are arranged in the housing. A tool holder 130 is slidably connected to the front of the transverse feed system 120. That is, by operating the control panel 100, the tool holder 130 is controlled to adjust its position transversely on the transverse feed system 120. The two are vertically raised as a whole on the longitudinal feed system 110, thereby processing the workpiece below. This is a prior art and will not be described in detail here.

[0043] A work box 200 is fixedly connected directly below the tool holder 130 and at the bottom of the shell. A processing table 210 with a rectangular structure is fixedly connected at the inner center of the work box 200. The outer dimensions of the processing table 210 are smaller than the inner dimensions of the work box 200, so that after the cooling liquid sprayed out from the cooling pipe installed on the work box 200 is collected by the work box 200, and a through hole for discharging the coolant is opened on the bottom surface of the work box 200, which plays a role in recycling and reuse; a filter screen is tightly fitted in the through hole to filter impurities such as iron filings.

[0044] Furthermore, a chip removal chamber 211 is provided in the middle of the front side of the processing table 210, and the rear inner wall of the chip removal chamber 211 extends to the rear side close to the processing table 210, that is, it does not pass through the rear side of the processing table 210; the interior of the chip removal chamber 211 is provided with a chip removal portion 300 for driving the iron chips on the processing table 210 out of the table in one direction. The workpiece cut and drilled on the processing table 210 will generate iron chips that fall onto the processing table 210, and a guard plate is fixed at the edge of the processing table 210 by bolts to gather the iron chips that fall onto the processing table 210. At this time, the iron chips are driven out in one direction of the processing table 210 by the chip removal portion 300, thereby avoiding affecting the workpiece placed on the processing table 210 and causing indentation. At the same time, it replaces the operation of manually brushing away the iron chips with a brush, thereby reducing labor intensity and reducing the risk of safe operation.

[0045] Specifically, such as Figure 3 and Figure 4 As shown, the chip removal part 300 is a conveyor belt 310 arranged in the chip removal chamber 211. A number of magnetic strips 311 are evenly spaced and bonded to the outer surface of the conveyor belt 310. The magnetic strips 311 extend along the front and rear directions of the chip removal chamber 211 to the outer edge of the conveyor belt 310. A conveying motor 313 for driving the conveyor belt 310 to circulate is provided at the two corners of the conveyor belt 310.

[0046] Furthermore, the width of the conveyor belt 310 is equal to the width of the chip removal chamber 211, so that the magnetic strip 311 can magnetically attract iron chips on the processing table 210 over a large area, ensuring that the area around the processed workpiece is clean and chip-free; belt rollers 312 are provided on the inner side of the conveyor belt 310 and at the four corners of the chip removal chamber 211. The inner ends of the belt rollers 312 are plugged into the rear inner wall of the chip removal chamber 211 and are rotatable, thereby supporting the conveyor belt 310 and extending it within the chip removal chamber 211;

[0047] The conveying motor 313 is coaxially connected to the belt roller 312 located above. The front end of the chip removal chamber 211 is tightly clamped with a sealing plate, and the conveying motor 313 is fixedly connected to the outer surface of the sealing plate by bolts.

[0048] When the magnetic chip suction device of the vertical machining center worktable of the present invention is in use, the conveying motor 313 is started to drive the conveyor belt 310 to circulate in one direction in the chip removal chamber 211, and then the plurality of magnetic strips 311 located on the upper layer pass through the top surface of the chip removal chamber 211 to magnetically attract the iron chips generated on the processing table 210 and move them to one end of the processing table 210 for accumulation, thereby ensuring that the processing table 210 remains clean when placing workpieces and processing.

[0049] Specifically, such as Figure 5-Figure 7As shown, the chip removal part 300 is composed of a number of conveying shafts 320 arranged side by side in a horizontal straight line, and a magnetic piece 321 is embedded on the outer side surface of the conveying shaft 320 and parallel to its axial direction. The outer side surface spacing of each two adjacent conveying shafts 320 is greater than the thickness of the two magnetic pieces 321, so that when the two adjacent conveying shafts 320 rotate, the two magnetic pieces 321 will not interfere with each other and hinder the movement; wherein the magnetic pieces 321 on each two adjacent conveying shafts 320 are arranged in opposite directions, and a sprocket motor 322 for driving the synchronous rotation of the plurality of conveying shafts 320 is provided at both ends of the entire body; so that the plurality of conveying shafts 320 arranged side by side can alternately use the magnetic piece 321 to magnetically attract iron chips and drive them to move to one end of the processing table 210 for gathering.

[0050] Furthermore, the rear end of the conveying shaft 320 is embedded in the inner wall of the chip removal chamber 211 and can rotate, and the front end of the conveying shaft 320 is embedded in the inner wall of the sealing plate and can rotate, so that the conveying shaft 320 is stably suspended at the top of the chip removal chamber 211; the front end of the conveying shaft 320 is coaxially connected to the sprocket 324, and the sprockets 324 of several conveying shafts 320 are meshed with chains 323; the sprocket motor 322 is coaxially connected to the outermost conveying shaft 320, and the sprocket motor 322 is fixedly connected to the outer surface of the sealing plate by bolts.

[0051] When the magnetic chip suction device of the vertical machining center worktable of the present invention is in use, the sprocket motor 322 is started to drive the multiple sprockets 324 to rotate in the same direction via the chain 323, thereby driving the multiple conveyor shafts 320 to rotate in the same direction, so that the multiple conveyor shafts 320 arranged side by side can alternately use the magnetic sheet 321 to magnetically attract iron chips and drive them to move to one end of the processing table 210 for aggregation, ensuring that the processing table 210 remains clean when placing workpieces and processing.

[0052] Specifically, such as Figures 8-10 As shown, the chip removal part 300 is a pair of pushing members 330 located at the top surface of the chip removal chamber 211, and a sliding sleeve 331 is connected between the pair of pushing members 330, and a spring 333 is provided in the sliding sleeve 331 for popping out the pushing member 330, so that the pushing member 330 can be extended and retracted in the sliding sleeve 331 to adapt to the different lengths and widths of the chip removal chamber 211. When the pushing member 330 is rotated in the length direction of the chip removal chamber 211, it is extended, and when the pushing member 330 is rotated in the width direction of the chip removal chamber 211, it is retracted into the sliding sleeve 331; the center of the bottom surface of the sliding sleeve 331 is coaxially connected to a pushing motor 332 that drives it to rotate.

[0053] Furthermore, the pusher 330, the magnetic strip 311, and the magnetic sheet 321 are all made of neodymium magnets to enhance their magnetism so as to magnetically attract the iron chips of the processing table 210 to move. A sliding groove 3311 is formed on the upper and lower surfaces of the sliding sleeve 331. The sliding groove 3311 extends along the length of the sliding sleeve 331 and does not pass through the outer end and the middle. The inner end of the pusher 330 is embedded with pins at the upper and lower ends, and the pins are slidably engaged with the sliding groove 3311, so that the pusher 330 is limited when it is extended and retracted to prevent it from slipping. The interior of the sliding sleeve 331 is connected, and the two ends of the spring 333 are bonded to the inner ends of the two pushers 330, thereby increasing the compression space of the spring 333, so that the pusher 330 can fully utilize the internal space of the sliding sleeve 331 to retract and retract.

[0054] An annular frame is sleeved on the outer side of the pushing motor 332 , and the annular frame is welded to the bottom surface of the chip removal chamber 211 , so that the pushing motor 332 can work stably.

[0055] In addition, Figure 11 and Figure 12 As shown, the center of the sliding sleeve 331 is coaxially arranged with the center of the chip removal chamber 211, and a plurality of fixed grooves 214 are provided at equal intervals on the top surface of the processing table 210. The fixed grooves 214 are used to clamp special fixtures to clamp the workpiece on the processing table 210. This is a prior art and will not be described in detail here. A chip opening 212 is provided between the bottoms of each two adjacent fixed grooves 214 located in the front half of the left end of the chip removal chamber 211. The chip openings 212 extend in an arc shape, and the radius of the arc is equal to the maximum rotation radius of the pushing member 330. When the pushing member 330 rotates, the iron chips in each fixed groove 214 in the front half and the iron chips on the surface of the processing table 210 are magnetically attracted to the chip opening 212, discharged to the rear half of the processing table 210, and then turned to one end of the processing table 210 to gather the iron chips.

[0056] Among them, a chip discharge port 213 is provided between the bottoms of each adjacent two fixed grooves 214 located in the rear half of the left end of the chip removal chamber 211, and several chip discharge ports 213 extend in an arc shape, and the arc radius is equal to the maximum rotation radius of the pusher 330, wherein several chip discharge ports 213 gradually narrow from front to back. This structure allows the accumulated iron chips to enter the rear half of the processing table, and then disperse the iron chips through the gradually narrowing chip discharge ports 213 into their respective fixed grooves 214, avoiding concentrated blockage of iron chips; since the right end of the processing table 210 does not have a chip passing port 212 and a chip discharge port 213, the chips enter the corresponding fixed grooves 214 from several chip discharge ports 213, and as the pusher 330 rotates, they are magnetically attracted and slide along the left end of the fixed groove 214 to the right end to accumulate.

[0057] When the magnetic chip suction device of the vertical machining center worktable of the present invention is in use, the pushing motor 332 is started to drive the sliding sleeve 331 to rotate, thereby driving a pair of pushing members 330 to adaptively rotate and extend in the chip removal chamber 211. When the pushing member 330 is in the front half of the processing table 210 and turns from its right end to the left end, it will magnetically attract the iron chips in the several fixed grooves in the front half and the iron chips on the processing table 210, slide to the chip passage 212, and discharge them into the rear half of the processing table 210. At this time, the pushing member 330 turns from the left end of the processing table 210 to its right end, and then disperses the iron chips into their respective fixed grooves 214 through the gradually narrowing chip discharge opening 213. The dispersed iron chips are then magnetically attracted as the pushing member 330 rotates and slides along the left end of the fixed groove 214 to its right end to accumulate, ensuring that the processing table 210 remains clean during workpiece placement and processing.

[0058] It should be noted that the above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention.
