[0004] To address the shortcomings of existing technologies, this utility model provides a chip removal device for CNC drilling and tapping machines. This device has the advantage of simultaneously cleaning chips present in the tapping through holes and the drill bit. It solves the problem that when a tapping machine is tapping a workpiece, in addition to chips inside the through holes, chips also exist on the inside of the drill bit used for tapping. The existing patent cannot remove chips from the drill bit, which causes interference when the drill bit taps other workpieces, affecting its practicality.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a chip removal device for a CNC drilling and tapping machine, comprising a worktable, a mounting frame fixed on the upper surface of the worktable, a tapping mechanism for tapping a workpiece on the mounting frame, and a fixing mechanism for fixing the tapped workpiece on the worktable.

[0006] The tapping mechanism includes a first electric push rod, the output shaft of which is fixed to the upper surface of the mounting bracket. The output shaft of the first electric push rod passes through and extends to the inner side of the mounting bracket and is fixed to a mounting plate. A dual-axis linear module is fixed to the lower surface of the mounting plate. A motor is fixed to the bottom end of the dual-axis linear module.

[0010] Furthermore, the number of connecting rods is four, and they are symmetrically distributed around the central axis of the fixing plate.

[0011] Furthermore, the fixing mechanism includes a second electric push rod, which is fixed to the right side of the worktable. The output shaft of the second electric push rod passes through and extends into the interior of the worktable, and is fixed with a first rack.

[0020] 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.

[0021] Please see Figure 1The chip removal device of the CNC drilling and tapping machine in this embodiment includes a worktable 1, a mounting frame 2 fixed on the upper surface of the worktable 1, a tapping mechanism 3 for tapping the workpiece on the mounting frame 2 to clean up the chips generated during the tapping operation, and a fixing mechanism 4 for fixing the workpiece during tapping on the worktable 1 to prevent the workpiece from shifting position during tapping.

[0022] Four supports 5 are fixed on the lower surface of the workbench 1 and are evenly distributed at the four corners of the lower surface of the workbench 1.

[0023] Please see Figure 2 To clean up debris generated during tapping, the tapping mechanism 3 in this embodiment includes a first electric push rod 301. The output shaft of the first electric push rod 301 is fixed to the upper surface of the mounting bracket 2. The output shaft of the first electric push rod 301 extends through and into the inner side of the mounting bracket 2, and is fixed to a mounting plate 302. The output shaft of the first electric push rod 301 drives the mounting plate 302 to move. A dual-axis linear module 303 is fixed to the lower surface of the mounting plate 302. The mounting plate 302 drives the dual-axis linear module 303 to move. The dual-axis linear module 303 moves, and a motor 304 is fixed at the bottom of the dual-axis linear module 303. The dual-axis linear module 303 can drive the motor 304 to move. A tapping drill bit 305 is fixed to the output shaft of the motor 304. The motor 304 drives the tapping drill bit 305 to move, thereby adjusting the position of the tapping drill bit 305 according to the position of the through hole. The output shaft of the motor 304 drives the tapping drill bit 305 to rotate, performing tapping work on the through hole. A chip removal component is provided on the dual-axis linear module 303.

[0024] In this example, there are two first electric push rods 301, which are symmetrically distributed about the central axis of the mounting bracket 2 to keep the mounting plate 302 stable when it moves.

[0025] It should be noted that the chip removal assembly includes a connecting rod 306. One end of the connecting rod 306 is fixed to the bottom end of the dual-axis linear module 303, and the other end of the connecting rod 306 is fixed to a fixing plate 307. A connecting pipe 308 is fixed to the lower surface of the fixing plate 307, and a nozzle 309 is connected to the bottom end of the connecting pipe 308. A connecting hole is provided on the upper surface of the fixing plate 307. The output shaft of the motor 304 is located inside the connecting hole, and the inner diameter of the connecting hole is larger than the outer diameter of the output shaft of the motor 304. At the same time, the output shaft of the motor 304 is also located inside the connecting pipe 308. A vacuum cleaner 310 is fixed to the upper surface of the fixing plate 307. The input end of the vacuum cleaner 310 is connected to a dust inlet pipe 311. The vacuum cleaner 310 transmits airflow into the dust inlet pipe 311. The other end of 11 extends through and to the bottom of the fixed plate 307 and is connected to the outside of the connecting pipe 308. The dust inlet pipe 311 transmits airflow into the connecting pipe 308. The output end of the vacuum cleaner 310 is connected to the dust outlet pipe 312. The upper surface of the workbench 1 is fixed with a dust storage box 313. The other end of the dust outlet pipe 312 is connected to the dust storage box 313. The debris generated during the tapping process is sucked in by the nozzle 309 and enters the dust storage box 313 through the dust outlet pipe 312 for storage. After the tapping is completed, the tapping drill bit 305 rotates out in the opposite direction. The nozzle 309 can clean the debris remaining on the tapping drill bit 305 to ensure that the next tapping work is not affected. There are four connecting rods 306, which are symmetrically distributed around the central axis of the fixed plate 307.

[0026] Please see Figure 3To prevent the workpiece from shifting position during tapping, the fixing mechanism 4 in this embodiment includes a second electric push rod 401. The second electric push rod 401 is fixed to the right side of the worktable 1. The output shaft of the second electric push rod 401 passes through and extends into the interior of the worktable 1, and a first rack 402 is fixed thereon. The output shaft of the second electric push rod 401 drives the first rack 402 to move. A gear 403 meshes with the back of the first rack 402, causing the first rack 402 to rotate. The lower surface of the gear 403 is rotatably connected to the inner bottom wall of the worktable 1 via a bearing. A second rack 404 meshes with the outer side of the gear 403, causing the gear 403 to move and making the movement of the second rack 404 opposite to that of the first rack 402. Connecting blocks 405 are fixed to the upper surfaces of both the first rack 402 and the second rack 404. 2. The second rack 404 drives the connecting blocks 405 on both sides to move. The upper surface of the worktable 1 has two sliding openings. The two connecting blocks 405 are located inside the two sliding openings, and the width of the sliding openings is adapted to the width of the connecting blocks 405. The upper surfaces of the two connecting blocks 405 extend through and to the upper side of the worktable 1, and are fixed with clamping plates 406. Support plates 407 are fixed on the opposite sides of the two clamping plates 406. The connecting blocks 405 drive the clamping plates 406 to move, so that the clamping plates 406 on both sides are close together. When the distance between the clamping plates 406 on both sides is about the same as the length of the workpiece, the workpiece is placed on the support plate 407. Then the clamping plates 406 on both sides continue to move, so that the clamping plates 406 fix the support plate 407 to prevent displacement during tapping. The support plate 407 can leave a certain gap between the workpiece and the worktable 1 to avoid affecting the worktable 1 during tapping.

[0027] In this example, the first rack 402 and the second rack 404 are symmetrically distributed around the central axis of the gear 403. A slide rod is fixed between the inner walls of the left and right sides of the worktable 1. The outer side of the slide rod is slidably connected to the inner side of the second rack 404, so that the first rack 402 and the second rack 404 are kept at the same height, and the movement trajectory of the second rack 404 is not deviated.

[0028] The working principle of the above embodiments is as follows:

[0029] (1) First, turn on the second electric push rod 401. The output shaft of the second electric push rod 401 drives the first rack 402 to move. The first rack 402 drives the gear 403 to rotate. The gear 403 drives the second rack 404 to move. The second rack 404 moves in the opposite direction to the first rack 402, so that the first rack 402 and the second rack 404 drive the connecting blocks 405 on both sides to move respectively. The connecting blocks 405 drive the clamping plate 406 to move, so that the clamping plates 406 on both sides are close together. When the distance between the clamping plates 406 on both sides is about the same as the length of the workpiece, place the workpiece on the support plate 407. Then continue to move the clamping plates 406 on both sides to fix the support plate 407 and prevent it from shifting during tapping.

[0030] (2) After fixing the workpiece, open the dual-axis linear module 303. The dual-axis linear module 303 can drive the motor 304 to move, and the motor 304 drives the tapping drill bit 305 to move, thereby adjusting the position of the tapping drill bit 305 according to the position of the through hole. After adjusting the position, open the first electric push rod 301. The output shaft of the first electric push rod 301 drives the mounting plate 302 to move, and the mounting plate 302 drives the dual-axis linear module 303 to move, thereby causing the tapping drill bit 305 to move down. At the same time, open the motor 304. The output shaft drives the tapping drill bit 305 to rotate, performing tapping work on the through hole. At this time, the vacuum cleaner 310 is turned on, and the vacuum cleaner 310 transmits air power to the dust inlet pipe 311. The dust inlet pipe 311 transmits air power to the connecting pipe 308. The debris generated during the tapping process is sucked in by the nozzle 309 and enters the dust collection box 313 through the dust outlet pipe 312 for storage. After the tapping is completed, the tapping drill bit 305 rotates out in the opposite direction. The nozzle 309 can clean the residual debris on the tapping drill bit 305 to ensure that the next tapping work is not affected.
