Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-8 The present invention provides a technical solution: a CNC horizontal machining center, including a machine tool 101 and an operating table 102 disposed on the machine tool 101.

The mounting shaft 501 on each magnetic cleaning component 5 is connected by a transmission component 7. A rotating component 6 for rotating the mounting shaft 501 is installed on the U-shaped frame 2. Through the rotation of the mounting plate 502 and the sliding action of the mounting plate 502 inside the T-slot 1034, the debris accumulated inside the T-slot 1034 is attracted to the magnetic block 504 in each mounting slot 503, thereby achieving magnetic cleaning of the debris accumulated inside the T-slot 1034.

[0033] Preferably, the rotating assembly 6 includes a mounting bracket 601 fixed to the upper end of the U-shaped frame 2, a connecting shaft 602 rotatably connected to the mounting bracket 601, one end of the connecting shaft 602 being fixed to one end of the mounting shaft 501, and a first motor 603 for driving the connecting shaft 602 mounted on the mounting bracket 601; the transmission assembly 7 includes gears 701 fixed on each mounting shaft 501, the gears 701 being concentrically arranged with the mounting shaft 501, and the gears 701 being connected to each other via a toothed belt 702; a support assembly 8 for supporting the toothed belt 702 is provided on the U-shaped frame 2; the connecting shaft 602 is driven to rotate by the first motor 603, and during the rotation of the connecting shaft 602, the mounting shaft 501 is driven to rotate, and during the rotation of the mounting shaft 501, the mounting disc 502 at one end of each mounting shaft 501 is driven to rotate through the transmission action between each gear 701 and the toothed belt 702.

[0034] Preferably, two sets of support components 8 are symmetrically arranged on the U-shaped frame 2. The support components 8 include an L-shaped frame 801 fixed on the U-shaped frame 2.

An air extraction assembly 11 for extracting air from the inside of the air inlet pipe 1002 is provided on the air inlet pipe 1002; the air extraction assembly 11 includes two one-way valves 1101 fixed inside the air inlet pipe 1002, the conduction direction of the two one-way valves 1101 being from one open end of the air inlet pipe 1002 to the other end, and a fixed pipe 1102 connected and fixed on the air inlet pipe 1002, the fixed pipe 1102 being located between the two one-way valves 1101. A piston plate 1103 is connected to 102 via a connecting assembly 12, and a pressing assembly 13 for pressing the piston plate 1103 is provided on the connecting shaft 602. Through the connecting assembly 12 and the pressing assembly 13, the push rod 1201 and the piston plate 1103 reciprocate on the fixed pipe 1102 as the connecting shaft 602 rotates. Since the conduction direction of the two one-way valves 1101 is from one end of the open end of the air inlet pipe 1002 to the other end, the reciprocating motion of the piston plate 1103 draws external gas into the space between the two one-way valves 1101 of the air inlet pipe 1002 and blows it out from one end of each blowing pipe 1003 toward the interior of the T-shaped groove 1034 through the pressing. The gas blown out through each blowing pipe 1003 plays a role in blowing and cleaning the accumulated debris inside the T-shaped groove 1034.

[0036] Preferably, the connecting assembly 12 includes a push rod 1201 slidably connected to one end of the fixed tube 1102. One end of the push rod 1201 is fixed to the piston plate 1103. A spring 1202 is sleeved on the outer side of the push rod 1201. The two ends of the spring 1202 are respectively connected to the piston plate 1103 and the inner wall of the fixed tube 1102. The extrusion assembly 13 includes a drive disk 1301 fixed on the connecting shaft 602. A plurality of protrusions are fixed around the drive disk 1301 for pushing against the push rod 1201. 1302; The rotation of the connecting shaft 602 drives the drive disk 1301 to rotate. During the rotation of the drive disk 1301, each protrusion 1302 abuts against one end of the push rod 1201 in sequence. Through the pushing action of the protrusion 1302 against one end of the push rod 1201 and the reset action of the spring 1202 on the connecting assembly 12 on the push rod 1201 after being subjected to force, the push rod 1201 and the piston plate 1103 reciprocate on the fixed tube 1102 as the connecting shaft 602 rotates.

[0037] Preferably, the moving component 3 includes two first L-shaped plates 301 fixed to one side of the platform 1033, a first connecting plate 302 disposed between the two first L-shaped plates 301, and a lead screw 303 rotatably connected between the two first L-shaped plates 301. The first connecting plate 302 and the lead screw 303 are meshed with each other. A second motor 304 for driving the lead screw 303 is mounted on the first L-shaped plate 301. The lead screw 303 is driven to rotate by the second motor 304. During the rotation of the lead screw 303, the U-shaped frame 2 is driven to move by the meshing transmission between the lead screw 303 and the first connecting plate 302 and the connection action of the first connecting plate 302. During the movement of the U-shaped frame 2, the U-shaped frame 2 is guided by the guide component 4, so that the U-shaped frame 2 under force moves above the platform 1033.

[0038] Preferably, the guide assembly 4 includes two second L-shaped plates 401 fixed to the outside of the platform 1033, a second connecting plate 402 is provided between the two second L-shaped plates 401, a guide rod 403 is slidably connected to the second connecting plate 402, the guide rod 403 is fixed between the two second L-shaped plates 401, the U-shaped frame 2 is fixed between the first L-shaped plate 301 and the second L-shaped plate 401, and a removal assembly 9 for removing debris adsorbed on the surface of the mounting plate 502 is provided between the first L-shaped plate 301 and the second L-shaped plate 401;

[0039] The guide rod 403 guides the sliding of the second connecting plate 402 and connects the second connecting plate 402 to the U-shaped frame 2, thus guiding the U-shaped frame 2 under stress.

[0040] Preferably, the removal component 9 includes a fixing frame 901 fixed between the first L-shaped plate 301 and the second L-shaped plate 401. A semi-circular groove 902 for the mounting plate 502 to be inserted is provided on one side of the fixing frame 901. A cleaning brush 903 is fixed on the inner wall of the semi-circular groove 902. After the debris accumulated inside the T-shaped groove 1034 is cleaned, the U-shaped frame 2 is driven to reset by the cooperation of the moving component 3 and the guiding component 4. During the reset process, each mounting plate 502 abuts against the cleaning brush 903 of each semi-circular groove 902 on the fixing frame 901. After the abutment is completed, each mounting plate 502 is rotated by the rotating component 6 and the transmission component 7. Since the cleaning brush 903 abuts against the outer side of the mounting plate 502, the rotation of the mounting plate 502 removes the debris magnetically attracted on the outer side of the mounting plate 502, which facilitates the continuous and efficient operation of subsequent magnetic cleaning.

[0041] Working Principle: During operation of the rotary table 103 on the CNC horizontal machining center, to clean the accumulated debris inside the T-slots 1034 on the platform 1033, the second motor 304 drives the lead screw 303 to rotate. During the rotation of the lead screw 303, the meshing transmission between the lead screw 303 and the first connecting plate 302, and the connection action of the first connecting plate 302, drive the U-shaped frame 2 to move. During the movement of the U-shaped frame 2, the guide assembly 4 guides the U-shaped frame 2, causing it to move above the platform 1033. During the movement of the U-shaped frame 2, the mounting shafts 501 on each magnetic cleaning assembly 5... The mounting discs 502 at each end slide on each T-slot 1034. During the sliding process, the first motor 603 drives the connecting shaft 602 to rotate. During the rotation of the connecting shaft 602, the mounting shaft 501 is driven to rotate. During the rotation of the mounting shaft 501, the mounting discs 502 at one end of each mounting shaft 501 are driven to rotate through the transmission action between each gear 701 and the toothed belt 702. Through the rotation of the mounting discs 502 and the sliding action of the mounting discs 502 inside the T-slot 1034, the debris accumulated inside the T-slot 1034 is attracted to the magnetic blocks 504 of each mounting slot 503, thereby achieving magnetic cleaning of the debris accumulated inside the T-slot 1034.

[0042] Furthermore, during the movement of the U-shaped frame 2 and the rotation of the connecting shaft 602, the rotation of the connecting shaft 602 drives the drive disk 1301 to rotate. During the rotation of the drive disk 1301, each protrusion 1302 abuts against one end of the push rod 1201 in sequence. Through the pushing action of the protrusion 1302 against one end of the push rod 1201 and the restoring action of the spring 1202 on the connecting assembly 12 on the push rod 1201 after being subjected to force, the push rod 1201 and the piston plate 1103 move with the rotation of the connecting shaft 602. The piston plate 1103 moves back and forth on the fixed pipe 1102. Since the conduction direction of the two one-way valves 1101 is from one end of the open end of the air inlet pipe 1002 to the other end, the reciprocating motion of the piston plate 1103 draws the external gas into the space between the two one-way valves 1101 of the air inlet pipe 1002 and blows it out from one end of each blowing pipe 1003 toward the inside of the T-shaped groove 1034 through the extrusion. The gas blown out through each blowing pipe 1003 plays a role in blowing and cleaning the accumulated debris inside the T-shaped groove 1034.

[0043] After the debris accumulated inside the T-slot 1034 is cleaned, the U-shaped frame 2 is driven to reset through the cooperation of the moving component 3 and the guiding component 4. During the reset process, each mounting plate 502 abuts against the cleaning brush 903 of each semi-circular groove 902 on the fixed frame 901. After the abutment is completed, each mounting plate 502 is rotated by the rotating component 6 and the transmission component 7. Since the cleaning brush 903 abuts against the outside of the mounting plate 502, the rotation of the mounting plate 502 removes the debris magnetically attracted on the outside of the mounting plate 502, which facilitates the continuous and efficient operation of subsequent magnetic cleaning.
