[0054] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0055] like Figure 1-Figure 14 As shown, a CNC slotting machine for plate processing, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , including a bed 1, both sides of the bed 1 are slidably connected with columns 6 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 holder 11 is installed at the front of the bottom of the spindle box 8, a plurality of cutting tools 12 are installed at the bottom of one side of the tool holder 11, a chip scraping mechanism 9 for removing burrs is installed at the bottom of the rear end of the tool holder 11, a chip removing mechanism 10 for adsorbing chips is installed at the bottom of the front of the spindle box 8, a discharge trough 2 is opened at the front end of the top surface of the bed 1, the bottom of the roller 906 is flush with the bottom of the scraper 907, a cleaning mechanism 13 is installed at the rear end and in the center between the two columns 6, and the cleaning mechanism 13 is used to push larger chips on the top surface of the plate into the discharge trough 2;

[0056] The chip shoveling mechanism 9 includes a limiting sleeve 901, two rod sleeves 903 are arranged inside the limiting sleeve 901, a knife rod 904 is sleeved inside the limiting sleeve 901, a spring 914 is fixedly installed on the top of the knife rod 904, a knife seat 905 is fixedly installed on the bottom of the knife rod 904, rollers 906 are movably installed at the front and rear ends of the bottom of the knife seat 905, a scraper 907 is installed on the top of the knife seat 905 near the front end, a knife locking bolt 908 is installed in the center of the top of the scraper 907, the knife locking bolt 908 is bolted to the knife seat 905, and limiting protrusions 909 are fixedly installed on the top of the knife seat 905 and on both sides of the knife locking bolts 908, and the scraper 907 is clamped with the limiting protrusion 909.

[0057] Specifically, when grooving the plate, the plate is placed on the conveyor roller 3 and then pushed to the workbench on the top of the bed 1. The tool holder 11 is driven up and down by the mechanism inside the spindle box 8, and then the tool 12 is driven to grooving. In the grooving process, the spindle box 8 makes an X-axis movement along the beam 7, and the column 6 makes a Z-axis movement along the bed 1. The tool rod 904 is squeezed by the spring 914, and the tool seat 905 is pressed down, so that the bottom of the roller 906 and the scraper 907 are in contact with the top of the plate, ensuring that the blade position of the scraper 907 is always in contact with the edge position of the groove. While the tool 12 is grooving, the scraper 907 moves forward to remove the burrs at the edge of the groove after grooving, and the rolling and support of the roller 906 are used to avoid the gap between the tool seat 905 and the plate. Friction occurs, causing the plate to be worn. The blade 907 is conveniently fixed to the blade holder 905 through the blade locking bolt 908 and the limiting protrusion 909. At the same time, after the blade locking bolt 908 is removed, the blade 907 can be easily replaced. Smaller debris formed during the grooving process and after removing burrs is adsorbed and removed by the chip removal mechanism 10 to prevent the debris from remaining in the grooved groove and 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 matter in the grooving area of ​​the plate to prevent foreign matter from remaining and affecting the operation of the tool 12. Larger debris cannot be adsorbed and is pushed into the discharge chute 2 by the cleaning mechanism 13 to prevent the debris from remaining on the top of the plate, making it easy to clean the debris generated by grooving.

At the same time, the filter frame 1008 is provided to cover the top of the negative pressure cylinder 1007 to prevent foreign matter from entering the negative pressure cylinder 1007. When the negative pressure fan 1014 starts to absorb debris, the debris follows the airflow and is filtered by the filter frame 1015. The scraper rod 1016 is driven by the negative pressure fan 1014 to scrape and clean the attached debris to prevent the debris from accumulating at the bottom of the filter frame 1015 and causing blockage.

[0074] Please refer to Figure 1 , Figure 2 and Figure 3 A presser foot 5 is installed on one side of the top of the bed 1, a chip collecting groove 4 is clamped at the front end of the bed 1, and the discharge groove 2 is arranged to be inclined forward.

[0075] Specifically, when grooving the plate, the plate is fixed by pressing the plate with the presser foot 5. After the cleaning mechanism 13 pushes the foreign matter and large debris on the top surface of the plate into the discharge chute 2, the foreign matter slides into the chip collecting chute 4 through the discharge chute 2, which is convenient for collecting the foreign matter and large debris and cleaning the foreign matter and large debris.

[0076] How it works

[0077] When grooving the plate, the plate is placed on the conveyor roller 3, and then pushed to the workbench on the top of the bed 1, and the plate is fixed by pressing the plate with the presser foot 5, and the tool holder 11 is driven to rise and fall through the mechanism inside the spindle box 8, thereby driving the tool 12 to grooving, and in the grooving process, the spindle box 8 makes an X-axis movement along the beam 7, and the column 6 makes a Z-axis movement along the bed 1, and the tool rod 904 is squeezed by the spring 914, and the tool seat 905 is pressed down, so that the bottom of the roller 906 and the scraper 907 are in contact with the top of the plate, ensuring that the blade position of the scraper 907 is always in contact with the edge of the groove. While the tool 12 is grooving, the scraper 907 moves forward to remove the burrs on the edge of the groove after grooving, and uses the rolling and support of the roller 906 to avoid friction between the knife seat 905 and the plate, which causes the plate to be worn. The scraper 907 is conveniently fixed to the knife seat 905 by the knife locking bolt 908 and the limiting protrusion 909. At the same time, the scraper 907 is conveniently replaced after the knife locking bolt 908 is removed. Smaller debris is formed during the grooving process and after removing the burrs. When the negative pressure fan 1014 is started, negative pressure is formed inside the negative pressure cylinder 1007, and the fine debris passes through the chip suction port 1013 in conjunction with the negative pressure air duct 1014. 09 enters the negative pressure cylinder 1007, and after being filtered by the filter frame 1015, the fine debris falls into the chip collecting groove 1002, which is convenient for collecting and processing the fine debris, avoiding the debris from entering the planed groove and affecting the planing accuracy, and avoiding the debris from causing secondary wear to the tool 12, thereby extending the service life of the tool 12. The debris follows the airflow and is filtered by the filter frame 1015. The scraper 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 filter frame 1015 and causing blockage. When the chip removal mechanism 10 follows the spindle box 8 to move along the Z axis , the foreign matter on the top surface of the plate is cleaned by cleaning the plate brush 1011 to prevent the foreign matter from affecting the operation of the tool 12, reduce the wear of the tool 12, and improve the planing accuracy. However, since large debris cannot be adsorbed, the cleaning mechanism 13 moves forward with the spindle box 8, and the elastic cleaning belt 1308 pushes the debris and foreign matter to both sides of the groove to prevent foreign matter and debris from entering the planed groove. After the foreign matter and large debris on the top surface of the plate are pushed into the discharge chute 2, they slide into the chip collecting chute 4 through the discharge chute 2, which is convenient for collecting foreign matter and large debris, and cleaning foreign matter and large debris.
