[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-6 This utility model provides a technical solution:
[0028] A CNC drilling machine includes a worktable 1, with a mounting frame 2 installed on the top of the worktable 1. The mounting frame 2 is connected to a water supply component 5 and a processing component 4. Both the processing component 4 and the water supply component 5 are connected to a circular cover 6. The processing component 4 is connected to a cleaning component 12, which contacts the inner wall of the circular cover 6. A baffle 3 is installed on the top of the worktable 1 directly below the circular cover 6. A clamping component 7 is connected to the side wall of the baffle 3. A collection box 9 is installed at the bottom of the worktable 1, and a filter component 8 is installed inside the collection box 9. Several sets of circular holes are opened on the top of the worktable 1 inside the baffle 3 and communicate with the collection box 9. Rectangular grooves 11 are opened on both the front and rear sides of the circular cover 6, and the rectangular grooves 11 are for leaving space for the clamping component 7.
[0029] Furthermore, the processing component 4 includes a cylinder 41, which is fixedly mounted on the top of the mounting frame 2. The output end of the cylinder 41 passes through the mounting frame 2 and is fixedly connected to the top of the circular cover 6. A motor 42 is installed inside the top of the circular cover 6, and a drill bit 43 is installed at the output end of the motor 42. The outer wall of the output end of the motor 42 is connected to the cleaning component 12. The output end of the cylinder 41 pushes the circular cover 6 down to cover the workpiece, and the output end of the motor 42 drives the drill bit 43 to continuously process the workpiece. At the same time, the cleaning component 12 continuously cleans the debris attached to the inner wall of the circular cover 6.
[0030] Furthermore, the cleaning component 12 includes a connecting rod 122, which is fixedly connected to the outer wall of the output end of the motor 42. A brush 121 is installed at the other end of the connecting rod 122. The brush 121 is in close contact with the inner wall of the circular cover 6. While the output end of the motor 42 drives the drill bit 43 to rotate, the connecting rod 122 will continuously drive the brush 121 to sweep off the debris attached to the inner wall of the circular cover 6.
[0031] Furthermore, the water supply assembly 5 includes a water tank 51, which is installed on the top of the mounting bracket 2. A water pump 53 is installed on the top of the circular cover 6. A corrugated hose 52 is connected between the inlet of the water pump 53 and the water tank 51. A nozzle 54 is installed between the outlet of the water pump 53 and the top of the inner part of the circular cover 6. The outlet of the nozzle 54 is aligned with the drill bit 43. When the drill bit 43 processes the workpiece, the water pump 53 will spray the water inside the water tank 51 through the corrugated hose 52 and the nozzle 54 onto the drill bit 43. This can not only cool the drill bit 43 and the workpiece, but also flush away debris.
[0032] Furthermore, the filter assembly 8 includes a chute 82, with two sets of chute 82 respectively opened on the left and right inner walls of the collection box 9. Slide strips 81 are slidably connected to the inner walls of both sets of chute 82, and a filter frame 83 is installed between the two sets of slide strips 81. A handle 84 is installed on the outer wall of the filter frame 83. A rectangular opening is left on the front outer wall of the collection box 9. The filter frame 83 can be pulled out from the rectangular opening at the front of the collection box 9 along the chute 82 using the handle 84 to clean the debris and residue inside the filter frame 83.
[0033] Furthermore, the clamping assembly 7 includes threaded rods 74. Both sets of threaded rods 74 pass through the front and rear side baffles 3 of the worktable 1 and are threadedly connected to the baffles 3. The ends of the threaded rods 74 located inside the baffles 3 are rotatably connected to clamping plates 72. A guide rod 73 is connected between the clamping plates 72 and the baffles 3. The guide rod 73 is slidably connected to the baffles 3. A turntable 71 is installed at the other end of the threaded rods 74. Rotating the turntable 71 causes the threaded rods 74 to drive the clamping plates 72 to move back and forth, thereby clamping workpieces of different sizes.
[0034] Furthermore, a drain pipe 10 is installed at the bottom of the collection box 9, and a valve is installed on the outer wall of the drain pipe 10. Opening the valve will allow the liquid inside the collection box 9 to be discharged through the drain pipe 10.
[0035] Working principle: After the workpiece is placed on top of the worktable 1 between the baffles 3, the workpiece is restrained by the clamping component 7. Then, the circular cover 6 is covered by the processing component 4, and the processing component 4 processes the workpiece. The water supply component 5 cools the processing component 4 and the workpiece. At the same time, the water supplied by the water supply component 5 can also wash away the debris generated during processing. During the processing process, the cleaning component 12 will continuously clean the inner wall of the circular cover 6 to prevent debris from adhering to the inside of the circular cover 6. The water flow washes the debris into the collection box 9. After being filtered by the filter component 8, the debris and liquid are separated, which is convenient for later cleaning.
