Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0025] Please refer to Figure 1 , 2 , 3, 4, 5, 6, the present utility model provides a technical solution: a numerical control drilling and tapping machine convenient for waste chip cleaning, including: a support workbench 1, a chip discharging hole 11 is opened at the top of the support workbench 1, a material receiving trough 16 matched with the chip discharging hole 11 is fixedly connected inside the support workbench 1, and a cleaning part is arranged inside the material receiving trough 16; a lifting plate 3 is lifted and placed above the support workbench 1, a rotating disk 6 is rotatably installed in the middle of the lifting plate 3, a processing part is arranged at the top of the rotating disk 6 for drilling and tapping processing, a splash-proof partition board 20 is slidably arranged outside the lifting plate 3, the splash-proof partition board 20 is made of transparent plastic material, an elastic shielding part 10 is arranged between the moving plate 14 and the support workbench 1 to prevent processing chips from entering the position of the driving part at the bottom, the moving plate 14 is slidably installed on the top of the support workbench 1, a bench vice 15 is installed at the top of the moving plate 14, and a driving part for driving the bench vice 15 to move horizontally is installed at the bottom of the moving plate 14.
[0026] It should be noted that the present utility model is equipped with a PLC controller and a corresponding operation panel. The workpiece to be processed is placed in the bench vise 15, and the corresponding control switch is turned on. The driving part drives the workpiece to move along the X and Y axes through the moving plate 14, so that the processing position of the workpiece corresponds to the processing part. The driving part drives the rotating disk 6 to rotate, so that the processing part outside the rotating disk 6 performs position switching. The lifting of the lifting plate 3 drives the processing part to contact the workpiece to realize processing. During this period, the splash-proof partition 20 contacts the supporting workbench 1. During the lifting and lowering of the lifting plate 3, the splash-proof partition 20 always covers the processing position, closes the processing position, and prevents processing debris from scattering. The debris enters the material collection groove 16 through the chip removal hole 11 and is centrally collected by the cleaning part, so as to facilitate the treatment of the processing debris.
[0027] Please refer to Figure 4 、 5 As shown in FIGS. 6, the cleaning part includes a connecting rod 17, and scraping plates 18 are fixedly connected to both ends of the connecting rod 17. A through hole matching the scraping plate 18 is provided on one side of the supporting workbench 1, and the scraping plate 18 is slidably connected to the material collection groove 16.
[0028] It should be noted that when the present utility model is cleaning, the scraping plate 18 located outside the supporting workbench 1 is pulled. The scraping plate 18 drives the scraping plate 18 located inside the material collection groove 16 to move through the connecting rod 17. While the scraping plate 18 slides inside the material collection groove 16, the scraping plate 18 scrapes and cleans the internal debris, so as to scrape the debris out of the material collection groove 16.
[0029] Please refer to Figure 1 As shown in FIG. 15, a first linear module 2 is fixedly connected to the top of the supporting workbench 1, and the moving slide of the first linear module 2 is fixedly connected to the lifting plate 3.
[0030] It should be noted that a baffle matching the splash-proof partition 20 is provided on one side of the first linear module 2 of the present utility model. When the bottom of the splash-proof partition 20 contacts the top of the supporting workbench 1, the splash-proof partition 20 contacts the baffle, realizing the sealing of the side of the splash-proof partition 20, so as to realize the partition of the processing position, prevent processing debris from being thrown out or splashed out, and make the debris stay near the chip removal hole 11 or fall from the chip removal hole 11.
[0031] Please refer to Figure 3 As shown in FIG. 23, the processing part includes a first motor 7 and a second motor 19 fixedly connected to the top of the rotating disk 6. The first motor 7 and the second motor 19 are symmetric about the axis of the rotating disk 6. A drill bit is fixedly connected to the output end of the first motor 7, a tap is fixedly connected to the output end of the second motor 19, a third motor 8 is fixedly connected above the lifting plate 3, a small gear 9 is fixedly connected to the output end of the third motor 8, and a large gear meshing with the small gear 9 is fixedly connected to the outside of the rotating disk 6.
[0032] It should be noted that the first motor 7, the second motor 19 and the third motor 8 of the present utility model are all servo motors. A concave hole for cooperating with the rotating disk 6 is provided at the top of the lifting plate 3. The drill bit and the tap both pass through the middle of the concave hole. When it is necessary to switch between the drill bit and the tap, the third motor 8 drives the large gear to rotate through the small gear 9, and the large gear drives the rotating disk 6 to rotate. The rotating disk 6 drives the first motor 7 and the second motor 19 to switch positions, so as to realize the correspondence between the drill bit and the tap and the processing position. After the switching is completed, the lifting plate 3 is driven to lift and lower by the first linear module 2. The lifting plate 3 drives the drill bit and the tap to lift and lower through the rotating disk 6. The first motor 7 and the second motor 19 drive the corresponding processing components to process the workpiece.
[0033] Please refer to Figure 1 As shown, a limiting rod 4 is fixedly connected to the top of the lifting plate 3. The limiting rod 4 is slidably connected to the splash-proof partition plate 20. A return spring 5 is provided outside the limiting rod 4 and above the lifting plate 3.
[0034] It should be noted that when the bottom of the splash-proof partition plate 20 of the present utility model contacts the support workbench 1, when the lifting plate 3 continues to descend, the splash-proof partition plate 20 slides outside the limiting rod 4, and the return spring 5 is compressed while sliding, so that the splash-proof partition plate 20 can protect the processing environment under different processing depths.
[0035] Please refer to Figure 1 、 2 As shown, the elastic shielding part 10 is a bellows cloth or a rubber pad. The driving part includes a second linear module 12 fixedly connected inside the support workbench 1. A third linear module 13 is fixedly connected to the moving slide of the second linear module 12. The second linear module 12 and the third linear module 13 are vertically arranged. A moving plate 14 is fixedly connected to the moving slide of the third linear module 13.
[0036] It should be noted that the first linear module 2, the second linear module 12 and the third linear module 13 of the present utility model are all screw linear modules. The screw linear module includes a bracket equipped with a guide rail, a moving slide slidably arranged on the guide rail, a screw system for driving the moving slide to move, and a servo motor for driving the screw to rotate. The screw system is composed of a screw and a nut. The nut is fixedly connected to the moving slide. The helical movement of the screw and the nut can convert the rotational movement into a linear movement. Thus, the servo motor drives the screw to rotate, and the screw drives the moving slide to move on the guide rail. The second linear module 12 drives the third linear module 13 to move along the Y-axis, and the third linear module 13 drives the moving plate 14 to move along the X-axis. When the moving plate 14 moves along the X and Y axes, the bellows cloth connects the outside of the moving plate 14 and the support workbench 1 through expansion and contraction, preventing the processing debris from falling outside the second linear module 12 and the third linear module 13, causing a situation that is difficult to clean.
