It can reduce the labor output and improve the processing efficiency;

[0003] The patent document with the publication number of "CN114289772B" discloses a "fully automatic numerically controlled four-sided grooving machine, which relates to the field of grooving machines and includes a bottom plate and a frame. Transverse grooves are provided on both sides of the bottom plate, and sliders are arranged inside the transverse grooves; this fully automatic numerically controlled four-sided grooving machine can well fix the sheet on the upper surface of the circular bearing plate, avoid the sheet from shifting during the grooving process and affecting the grooving effect, and is convenient for workers to replace the grooving knives worn due to long-term use". Although it can well fix the sheet on the upper surface of the circular bearing plate and avoid the sheet from shifting during the grooving process and affecting the grooving effect, after the grooving is completed, burrs will be formed at the edge of the groove opening and cannot be removed, and it is necessary to polish again after the grooving is completed to remove the burrs, which is rather troublesome. Moreover, the chips formed during the grooving process cannot be cleaned in time, and the remaining chips are likely to cause secondary wear to the tool and reduce the service life of the tool.

[0020] Specifically, it avoids the influence of foreign objects on the operation of the tool, reduces the wear of the tool, and improves the grooving accuracy.

[0021] As a further solution of the present invention, the chip removal mechanism further includes a negative pressure cylinder fixedly installed on the top surface of the chip removal box by bolts. A negative pressure fan is fixedly installed in the center of the negative pressure cylinder. A second filter screen frame is fixedly installed below the negative pressure fan inside the negative pressure cylinder. A second chip collection groove is clamped inside the chip removal box. Chip suction ports are opened through the bottom ends of the inner walls on both sides of the chip removal box.

[0026] Specifically, it is convenient to collect foreign objects and relatively large chips, and to clean foreign objects and relatively large chips.

[0027] The beneficial effects of the present invention are as follows:

[0028] 1. While the tool of the present invention performs grooving, the scraping blade moves forward to remove the burrs at the edge of the groove opening after grooving, and uses the rolling and supporting of the first roller to prevent friction between the tool holder and the plate, resulting in wear of the plate, which is convenient for removing the burrs at the edge of the groove opening;

[0029] 2. When the screw rod of the present invention is rotated, the screw sleeve is driven to move by the screw rod, which is convenient to adjust the distance between the two tool holders as needed, so that the scraping blade can adapt to grooves of different widths, ensuring that the scraping blade can remove the burrs at the edges of grooves of different widths;

[0030] 3. After loosening the second locking bolt of the present invention, the adjusting rod is slid along the direction of the adjusting groove, which is convenient to adjust the height of the entire cleaning mechanism. After the adjustment is completed, the second locking bolt is tightened to fix the adjusting rod, which is convenient to position the entire cleaning mechanism, and is convenient to adjust the height of the cleaning mechanism when grooving plates of different thicknesses;

[0031] 4. After starting the electric telescopic rod of the present invention, the guide wheel is driven to move, and the elastic cleaning belt is pushed out in a "V" shape through the guide wheel, which is convenient to tighten the elastic cleaning belt. At the same time, when pushing the chips and foreign objects on the top surface of the plate, it is convenient to push the chips and foreign objects to both sides of the groove, preventing foreign objects and chips from entering the grooved groove;

[0032] 5. The present invention squeezes the limiting rod through the second spring to press the cleaning brush plate and the second roller on the top surface of the plate. When the chip removal mechanism moves along the Z-axis following the main spindle box, the foreign objects on the top surface of the plate are swept by the cleaning brush plate, preventing foreign objects from affecting the operation of the tool, reducing the wear of the tool, and improving the grooving accuracy;

[0033] 6. After the negative pressure fan of the present invention is started, a negative pressure is formed inside the negative pressure cylinder. Fine debris enters the negative pressure cylinder through the chip suction port in cooperation with the negative pressure air duct. After being filtered by the second filter screen frame, the fine debris falls into the second chip collection groove, which is convenient for collecting and processing the fine debris, avoiding the debris from entering the planed groove and affecting the planing groove accuracy, and avoiding the debris from causing secondary wear to the tool, thus prolonging the service life of the tool.

[0034] 7. After the negative pressure fan of the present invention starts to adsorb debris, the debris is filtered by the second filter screen frame following the air flow, and the scraping rod driven by the negative pressure fan scrapes and cleans the attached debris, avoiding the accumulation of debris at the bottom of the second filter screen frame and causing blockage.

[0054] To make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0055] As Figures 1 - 14 shown, a numerically controlled grooving machine for sheet processing, please refer specifically to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 andFigure 6 , including a bed body 1, with columns 6 slidably connected to both sides of the bed body 1 near the top. A crossbeam 7 is fixedly installed between the two columns 6 near the top. A spindle box 8 is installed outside the crossbeam 7. A tool rest 11 is installed through the front of the bottom of the spindle box 8. A number of cutting tools 12 are installed on one side of the tool rest 11 near the bottom. A chip removing mechanism 9 for removing burrs is installed at the back of the tool rest 11 near the bottom. A chip removing mechanism 10 for adsorbing chips is installed at the front of the bottom of the spindle box 8. A discharge chute 2 is opened through the front end of the top surface of the bed body 1. The bottom of the roller 906 is flush with the bottom of the cutting blade 907. A cleaning mechanism 13 is installed between the two columns 6 at the rear and in the middle position. The cleaning mechanism 13 is used to push the larger chips on the top surface of the plate into the discharge chute 2;

[0056] The chip removing mechanism 9 includes a limit sleeve 901. Two rod sleeves 903 are arranged inside the limit sleeve 901. A tool shank 904 is sleeved inside the limit sleeve 901. A first spring 914 is fixedly installed at the top of the tool shank 904. A tool holder 905 is fixedly installed at the bottom of the tool shank 904. Two rollers 906 are movably installed at the front and rear of the bottom of the tool holder 905. A cutting blade 907 is installed at the front of the top of the tool holder 905. A locking tool bolt 908 is installed through the middle of the top of the cutting blade 907. The locking tool bolt 908 is bolted to the tool holder 905. Limit protrusions 909 are fixedly installed on both sides of the top of the tool holder 905 and on both sides of the locking tool bolt 908. The cutting blade 907 is clamped with the limit protrusions 909.

[0057] Specifically, when grooving the plate, place the plate on the conveying roller 3 and then push it to the workbench on the top of the bed body 1. The mechanism inside the main spindle box 8 drives the tool rest 11 to move up and down, thereby driving the tool 12 to groove. During the grooving process, the main spindle box 8 moves along the cross beam 7 in the X-axis direction, and the column 6 moves along the bed body 1 in the Z-axis direction. The spring 914 squeezes the tool bar 904 and presses down the tool holder 905, so that the bottoms of the first roller 906 and the scraping tool 907 are in contact with the top of the plate, ensuring that the cutting edge position of the scraping tool 907 always fits the edge position of the groove opening. While the tool 12 is grooving, the scraping tool 907 moves forward to remove the burrs at the edge of the groove opening after grooving, and uses the rolling and support of the first roller 906 to prevent friction between the tool holder 905 and the plate, resulting in wear of the plate. The scraping tool 907 is fixed to the tool holder 905 by the locking tool bolt 908 and the limit projection 909. At the same time, it is convenient to replace the scraping tool 907 after removing the locking tool bolt 908. The smaller debris formed during the grooving process and after removing the burrs is adsorbed and removed by the chip removal mechanism 10, preventing the debris from remaining in the grooved groove, causing secondary wear to the tool 12, affecting the grooving process of other tools 12, and reducing the grooving accuracy. At the same time, the chip removal mechanism 10 sweeps away foreign objects in the grooving area of the plate to prevent foreign objects from remaining and affecting the operation of the tool 12. The larger debris, which cannot be adsorbed, is pushed by the cleaning mechanism 13 into the discharge chute 2 to prevent the debris from remaining on the top of the plate, facilitating the cleaning of the debris generated by grooving.

[0058] Please refer specifically to Figure 4 、 Figure 5 and Figure 6 The chip scraping mechanism 9 further includes two sliding grooves 902 opened in the front and rear sleeve bodies of the limit sleeve 901. Two sliders 910 are fixedly installed at the front end of the first rod sleeve 903.

The wire sleeve 913 is slidably connected to the sliding rod 911. Threads with the same length and opposite directions are provided at both ends of the lead screw 912. The limit sleeve 901 is fixedly connected to the tool rest 11 by bolts.

[0059] Specifically, the rod sleeve one 903 is limited by setting the limit sleeve 901, and the wire sleeve 913 is limited by setting the sliding rod 911. When the lead screw 912 is rotated, the wire sleeve 913 is driven to move by the lead screw 912, facilitating the adjustment of the distance between the two tool holders 905 as needed, facilitating the adaptation of the shovel 907 to grooves of different widths, ensuring that the shovel 907 can remove the burrs at the edges of grooves of different widths. At the same time, the slider 910 cooperates with the chute 902 to improve the stability of the movement of the rod sleeve one 903.

[0060] Please refer specifically to Figure 7 and Figure 8 , the cleaning mechanism 13 includes an adjusting rod 1301. Locking bolts two 1309 are threadedly connected to both sides near the front and rear ends of the adjusting rod 1301.

A fixing rod 1307 is fixedly installed at the bottom of the second sliding sleeve 1303. An elastic cleaning belt 1308 is fixedly installed between the two fixing rods 1307 by bolts at a position near the bottom end.

[0063] Specifically, after loosening the locking bolts one 1304, the second sliding sleeve 1303 is slid along the direction of the adjusting rod 1301, facilitating the adjustment of the distance between the two fixing rods 1307, and further adjusting the cleaning length of the elastic cleaning belt 1308, improving the adaptability of the cleaning mechanism 13, and facilitating the cleaning of the top surfaces of plates of different widths.

[0064] Please refer specifically to Figure 7 and Figure 8, the cleaning mechanism 13 further includes an electric telescopic rod 1305 fixedly installed at the front end of the first sliding sleeve 1302. The end of the piston rod of the electric telescopic rod 1305 is fixedly installed with a guide wheel 1306, and the guide wheel 1306 is located behind the elastic cleaning belt 1308.

[0065] Specifically, after loosening the first locking bolt 1304, slide the first sliding sleeve 1302 along the direction of the adjusting rod 1301, which is convenient for adjusting the positions of the electric telescopic rod 1305 and the guide wheel 1306, so that the guide wheel 1306 and the cutter 12 are in the same straight line. Then start the electric telescopic rod 1305 to drive the guide wheel 1306 to move, and push out the elastic cleaning belt 1308 into a "V" shape through the guide wheel 1306, which is convenient for tensioning the elastic cleaning belt 1308. At the same time, when pushing the debris and foreign objects on the top surface of the plate, it is convenient to push the debris and foreign objects to both sides of the groove to prevent foreign objects and debris from entering the planed groove.

[0066] Please refer specifically to Figure 9 、 Figure 11 and Figure 12 , the chip removal mechanism 10 includes a chip removal box 1001. At the positions of the top of the chip removal box 1001 that are rearward and on both sides, rail sleeves 1003 are fixedly installed. A guide rail 1004 is slidably connected inside the rail sleeves 1003. At the position of the top of the chip removal box 1001 that is rearward and between the two rail sleeves 1003, two limiting rods 1005 are fixedly installed. A second spring 1018 is fixedly installed at the top of the limiting rod 1005. A second rod sleeve 1006 is arranged at the outer part of the limiting rod 1005 near the top. The top of the second spring 1018 is fixedly connected to the second rod sleeve 1006. The second rod sleeve 1006 is sleeved on the limiting rod 1005. The second rod sleeve 1006 and the guide rail 1004 are fixedly connected to the main spindle box 8.

[0067] Specifically, the second rod sleeve 1006 is set to limit the limiting rod 1005, the guide rail 1004 is set to limit the rail sleeve 1003, and the second spring 1018 is used to squeeze the limiting rod 1005, which is convenient for the chip removal mechanism 10 to adjust the height to adapt to plates of different thicknesses.

[0068] Please refer specifically to Figure 9 and Figure 10 , the chip removal mechanism 10 further includes a second roller 1012 movably installed at the rear and the middle of the bottom of the chip removal box 1001. An installation groove 1010 is opened through the front end of the bottom of the chip removal box 1001, and a cleaning brush plate 1011 is clamped inside the installation groove 1010.

[0069] Specifically, the limiting rod 1005 is squeezed by the second spring 1018, pressing the cleaning brush plate 1011 and the second roller 1012 against the top surface of the plate. When the chip removal mechanism 10 moves along the Z-axis following the spindle box 8, the foreign matters on the top surface of the plate are cleaned by the cleaning brush plate 1011, preventing the foreign matters from affecting the operation of the tool 12, reducing the wear of the tool 12, and improving the grooving accuracy.

[0070] Please refer specifically to Figure 12 、 Figure 13 and Figure 14 In addition, the chip removal mechanism 10 further includes a negative pressure cylinder 1007 fixedly installed on the top surface of the chip removal box 1001 through bolts.

The interior of the negative pressure cylinder 1007 is communicated with the chip suction ports 1013 through the negative pressure air ducts 1009.

[0071] Specifically, during the grooving process of the tool 12, fine chips are formed. After the burrs at the edge of the groove are removed by the shovel 907, chips are also generated. When the negative pressure fan 1014 is started, a negative pressure is formed inside the negative pressure cylinder 1007. The fine chips enter the negative pressure cylinder 1007 through the chip suction ports 1013 in cooperation with the negative pressure air ducts 1009. After being filtered by the second filter screen frame 1015, the fine chips fall into the second chip collection groove 1002, facilitating the collection and treatment of the fine chips, preventing the chips from entering the grooved area and affecting the grooving accuracy, and avoiding secondary wear of the tool 12 caused by the chips, thus prolonging the service life of the tool 12.

[0072] Please refer specifically to Figure 12 、 Figure 13 and Figure 14 In addition, the chip removal mechanism 10 further includes a scraping rod 1016 fixedly installed at the bottom of the negative pressure fan 1014, and the top surface of the scraping rod 1016 is flush with the bottom surface of the second filter screen frame 1015. The cross-section of the scraping rod 1016 is in the shape of an isosceles triangle. A magnetic ring 1017 is fixedly installed through the top of the negative pressure cylinder 1007. A first filter screen frame 1008 is arranged on the top of the magnetic ring 1017, and the first filter screen frame 1008 is magnetically connected to the magnetic ring 1017.

[0073] Specifically, by setting the magnetic ring 1017 to connect the first filter screen frame 1008, it is convenient to disassemble and install the first filter screen frame 1008. At the same time, the first filter screen frame 1008 is set to cover the top of the negative pressure cylinder 1007 to prevent foreign objects from entering the negative pressure cylinder 1007. When the negative pressure fan 1014 starts to adsorb debris, the debris follows the airflow and is filtered by the second filter screen frame 1015. The scraping rod 1016 is driven by the negative pressure fan 1014 to scrape and clean the attached debris, preventing the debris from accumulating at the bottom of the second filter screen frame 1015 and causing blockage.

[0074] Please refer specifically to Figure 1 , Figure 2 and Figure 3 , a presser foot 5 is installed on one side near the top of the bed body 1, a first chip collecting groove 4 is clamped through the front end of the bed body 1, and the discharge chute 2 is arranged to incline forward.

[0075] Specifically, when grooving the board, the board is fixed by pressing the board with the presser foot 5. After the cleaning mechanism 13 pushes the foreign objects and larger debris on the top surface of the board into the discharge chute 2, they slide into the first chip collecting groove 4 through the discharge chute 2, facilitating the collection of foreign objects and larger debris and the cleaning of foreign objects and larger debris.

[0076] Working principle

[0077] When grooving a plate, place the plate on the conveyor roller 3, and then push it to the workbench on the top of the bed body 1. Then, fix the plate by pressing it tightly with the pressure foot 5. Drive the tool holder 11 to move up and down through the mechanism inside the main spindle box 8, thereby driving the tool 12 to groove. During the grooving process, the main spindle box 8 moves along the cross beam 7 in the X-axis direction, and the column 6 moves along the bed body 1 in the Z-axis direction. Squeeze the tool bar 904 through the first spring 914 and press down the tool holder 905, so that the bottoms of the first roller 906 and the scraping tool 907 contact the top of the plate, ensuring that the cutting edge position of the scraping tool 907 always fits the edge position of the groove opening. While the tool 12 is grooving, the scraping tool 907 moves forward to remove the burrs at the edge of the groove opening after grooving. By using the rolling and support of the first roller 906, it is possible to avoid friction between the tool holder 905 and the plate, resulting in wear of the plate. It is convenient to fix the scraping tool 907 to the tool holder 905 through the locking tool bolt 908 and the limit protrusion 909. At the same time, it is convenient to replace the scraping tool 907 after removing the locking tool bolt 908. For the smaller debris formed during the grooving process and after removing the burrs, when the negative pressure fan 1014 is started, a negative pressure is formed inside the negative pressure cylinder 1007. The fine debris enters the negative pressure cylinder 1007 through the chip suction port 1013 and the negative pressure air duct 1009. After being filtered by the second filter screen frame 1015, the fine debris falls into the second chip collection groove 1002, which is convenient for collecting and processing the fine debris, avoiding the debris from entering the grooved slot and affecting the grooving accuracy, and avoiding the debris from causing secondary wear to the tool 12, thereby prolonging the service life of the tool 12. The debris is filtered by the second filter screen frame 1015 following the air flow, and the scraping rod 1016 is driven by the negative pressure fan 1014 to scrape and clean the attached debris, avoiding the accumulation of debris at the bottom of the second filter screen frame 1015 and causing blockage. When the chip removal mechanism 10 moves along the Z-axis following the main spindle box 8, the foreign matters on the top surface of the plate are swept by the cleaning brush 1011, avoiding the foreign matters from affecting the operation of the tool 12, reducing the wear of the tool 12, and improving the grooving accuracy. Since the larger debris cannot be adsorbed, when the cleaning mechanism 13 moves forward following the main spindle box 8, the debris and foreign matters are pushed to both sides of the groove by the elastic cleaning belt 1308, avoiding the foreign matters and debris from entering the grooved slot. After the foreign matters and larger debris on the top surface of the plate are pushed into the discharge chute 2, they slide into the first chip collection groove 4 through the discharge chute 2, which is convenient for collecting the foreign matters and larger debris and facilitating the cleaning of the foreign matters and larger debris.
