[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0045] See also Figure 1-8 , the present invention provides a technical solution:

[0046] Five-axis machining center worktable cleaning device, including:

[0047] The table cleaning unit 1 is arranged at the upper end of the workbench body 100 and is used to clean the chips on the upper end of the workbench;

[0048] The track cleaning unit 2 includes a chip removal assembly 22 slidably disposed in the guide rail 101 of the workbench body 100 for blowing out the chips in the guide rail 101 in all directions, and an air inlet assembly 21 disposed on one side of the chip removal assembly 22 for supplying air to the chip removal assembly 22;

[0049] The propulsion unit 3 is arranged on the same side of the table cleaning unit 1 and the track cleaning unit 2, and is used to drive the table cleaning unit 1 and the track cleaning unit 2 to move synchronously and perform secondary cleaning on the track after the chip removal assembly 22 removes chips.

[0050] It should be noted that: when the workbench body 100 needs to be cleaned of chips, the chip removal assembly 22 is inserted into the guide rail 101 and the table cleaning unit 1 is located at the upper end of the workbench body 100, and the propulsion unit 3 is pushed. The propulsion unit 3 simultaneously drives the chip removal assembly 22 and the table cleaning unit 1 to move along the guide rail 101 and the workbench body 100 respectively, so that the chips in the guide rail 101 and the upper end of the workbench body 100 are cleaned synchronously. In addition, after the chip removal assembly 22 performs a preliminary cleaning of the guide rail 101, the propulsion unit 3 performs a secondary cleaning of the debris adhered to the inner wall of the guide rail 101 and difficult to be discharged by the chip removal assembly 22, thereby cleaning the chips in the guide rail 101 while cleaning the upper end of the workbench body 100.

[0051] As an improvement, Figure 2-5 As shown, the propulsion unit 3 includes:

[0052] A push rod 32 extends from the upper end of the workbench body 100 to the inside of the guide rail 101;

[0053] A handle 31 is fixedly connected to the upper end of the push rod 32 and is used to push the push rod 32;

[0054] A chip pusher block 33 is fixedly connected to the lower end of the push rod 32 and is located inside the guide rail 101. A polyurethane material layer 34 is provided on the outer side of the chip pusher block 33 to contact the inner wall of the guide rail 101 and is used for secondary cleaning of the inner wall of the track after the chip removal assembly 22 removes chips.

[0055] Preferably, the polyurethane material layer 34 can be connected to the chip pusher block 33 by a snap, and according to the elasticity and wear resistance of the polyurethane material itself, the polyurethane material layer 34 has a better cleaning effect on the guide rail 101 and extends the service life of the polyurethane material layer 34.

[0056] Further, such as Figure 6 As shown, the air inlet assembly 21 includes:

[0057] The limiting sleeve 211 is fixedly connected to one side of the push rod 32 and is located inside the guide rail 101;

[0058] The air inlet pipe 212 is disposed inside the push rod 32 . The air inlet 213 of the air inlet pipe 212 is close to the handle 31 . The air outlet of the air inlet pipe 212 is connected to the inside of the limiting sleeve 211 .

[0059] It should be supplemented that: the inlet of the air inlet 213 is connected to a pipeline installed on one side of the air pump, which is used to blow air into the air inlet pipe 212, wherein the pipeline and the air pump are not drawn in the figure.

[0060] As an improvement, Figure 5-7 As shown, the chip removal assembly 22 includes:

[0061] A rotating blower mechanism 221 is rotatably disposed at one end of the limiting sleeve 211 and is used to switch the wind direction of the wind discharged from the air inlet pipe 212;

[0062] A driven gear 222, fixedly sleeved on the outside of the rotating blower mechanism 221;

[0063] A driving gear 223 is meshed with the outside of the driven gear 222 and is used to drive the rotating blower mechanism 221 to rotate relative to the limiting sleeve 211;

[0064] A driving motor 224 is mounted on one end of the chip pusher block 33 opposite to the limiting sleeve 211. The driving end of the driving motor 224 is fixedly connected to the driving gear 223 via a driving shaft 2241. The driving shaft 2241 is rotatably connected to the inside of the chip pusher block 33.

[0065] A protective cover 225 for protecting the driving gear 223 and the driven gear 222 is connected to one side of the chip pusher block 33 and located on the outside of the driving gear 223 and the driven gear 222 by screws to prevent chips from adhering to the outside of the driving gear 223 and the driven gear 222 and causing transmission obstruction, wherein the screws are not drawn in the figure.

[0066] Further, such as Figure 7 As shown, the rotating blower mechanism 221 is provided with a round table surface at one end opposite to the limiting sleeve 211, and the round table surface is obliquely connected with an oblique blow pipe 2211 communicating with the air inlet pipe 212, so as to blow off the chips adhered to the inside of the guide rail 101;

[0067] The rotating blower mechanism 221 is located at one end of the limiting sleeve 211 and is fixedly connected to a limiting ring 2213 . The limiting ring 2213 is rotatably connected to the inside of the limiting sleeve 211 to limit the rotating blower mechanism 221 .

[0068] Furthermore, the rotating blower mechanism 221 is provided with a straight blow pipe 2212 parallel to the extending direction of the guide rail 101 at the end surface of the truncated table surface;

[0069] The straight blowing pipe 2212 is communicated with the air inlet pipe 212 and is used to blow out the chips remaining in the guide rail 101 after the oblique blowing pipe 2211 blows out of the guide rail 101 .

[0070] As an improvement, Figure 3-4 , Figure 8 As shown, the table cleaning unit 1 comprises:

[0071] A U-shaped frame 11, fixedly connected to one side of the push rod 32 and located above the workbench body 100;

[0072] A lifting rod 13 is connected to the inside of the U-shaped frame 11 by sliding up and down. The lifting rod 13 is in an N-shape, and a threaded hole 131 is provided in the middle of the upper end thereof;

[0073] A cleaning rod 14 is fixedly connected to the lower end of the lifting rod 13 and is used to move along the upper end of the workbench body 100 to clean the chips;

[0074] The threaded rod 12 extends from the upper end of the U-frame to the lower end of the U-shaped frame 11 through the threaded hole 131. The threaded rod 12 is threadedly connected to the threaded hole 131 to drive the lifting rod 13 to move up and down inside the U-shaped frame 11;

[0075] The upper end of the threaded rod 12 is fixedly connected with a knob 121 for rotating and adjusting the threaded rod 12 . The upper and lower ends of the outer side of the threaded rod 12 and located at the U-shaped frame 11 are fixedly sleeved with limiting rings for limiting the threaded rod 12 inside the U-shaped frame 11 .

[0076] Furthermore, one end of the cleaning rod 14 in the forward direction is fixedly connected with a chip limiting rod 15 near both sides, which is used to accommodate the cleaned chips in a U-shaped area formed by cooperating with the cleaning rod 14.

[0077] It should be noted that: in the specific implementation process of the present invention, Figure 1-7 As shown, when the workpiece is processed and the workbench body 100 needs to clean the chips, the handle 31 is held by hand, and the chip pusher block 33 is aligned with the guide rail 101 to be cleaned, and the handle 31 is pushed. The handle 31 drives the chip pusher block 33 to move forward along the guide rail 101 through the push rod 32. The chip pusher block 33 drives the rotating blower mechanism 221 to move forward along the guide rail 101 through the limit sleeve 211, and the air pump connected to the air inlet 213 is started. The air pump blows the air through the air inlet 213, The air inlet pipe 212 and the rotating air blower mechanism 221 are inside, and the rotating air blower mechanism 221 blows out air through the straight blowing pipe 2212 and the oblique blowing pipe 2211, respectively. The oblique blowing pipe 2211 blows the wind toward the inner wall of the guide rail 101, so that the chips adhering to the inner wall of the guide rail 101 are blown off, and the straight blowing pipe 2212 blows out the chips originally remaining on the guide rail 101 and blown off by the oblique blowing pipe 2211 directly from the guide rail 101, so that the chips in the guide rail 101 are quickly discharged;

[0078] like Figure 4-5As shown, during the process of the rotating blower mechanism 221 moving forward along the guide rail 101, the driving motor 224 is started, the driving motor 224 drives the driving gear 223 to rotate through the driving shaft 2241, the driving gear 223 drives the rotating blower mechanism 221 to rotate through the driven gear 222, and the rotating blower mechanism 221 drives the oblique blow pipe 2211 to rotate continuously, so that the oblique blow pipe 2211 can blow off the chips in different corners of the guide rail 101, and the chips in the entire guide rail 101 are cleaned without dead corners;

[0079] like Figure 4-5 As shown, when the chip pusher block 33 passes through the polyurethane material layer 34 and moves forward along the inner wall of the guide rail 101, the chip pusher block 33 passes through the polyurethane material layer 34 and moves forward along the inner wall of the guide rail 101, so that when the chip removal assembly 22 cannot blow off a small amount of chips that are firmly adhered to the guide rail 101, the polyurethane material layer 34 can further scrape them off and take them out of the guide rail 101, and the cleaning effect is good;

[0080] like Figure 3 , Figure 8 As shown, for the chips remaining on the upper end of the workbench body 100, the present invention rotates the knob 121 after moving the chip pusher block 33 into the guide rail 101. The knob 121 drives the threaded rod 12 to rotate in the U-shaped frame 11. The threaded rod 12 drives the lifting rod 13 to move downward through the threaded cooperation with the threaded hole 131. The lifting rod 13 drives the cleaning rod 14 to move downward until it contacts the upper end surface of the workbench body 100, so that when the handle 31 is pushed forward, the handle 31 pushes the U-shaped frame 11 forward through the push rod 32, and the U-shaped frame 11 drives the cleaning rod 14 to move forward along the upper end of the workbench body 100 through the lifting rod 13, so that the residual chips on the upper end of the workbench body 100 are pushed out by the cleaning rod 14 along the upper end of the workbench body 100, so that the chips on the upper end of the workbench body 100 and the guide rail 101 can be cleaned synchronously.
