The vibration cleaning mechanism 2 includes a vibration plate 201 and a vibration motor 202 arranged inside the chip collecting cover 1. The vibration plate 201 is connected to the inner wall of the chip collecting cover 1 through a plurality of compression springs 203. The chip conveying mechanism 3 includes a screw conveyor 301 and a driving motor 302 arranged at the bottom of the chip collecting cover 1. The feed port of the screw conveyor 301 is connected to the inside of the chip collecting cover 1. At the lower end of the debris conveying mechanism 3, the chip collecting cover 1 includes a receiving part 101, a discharge part 102, a discharge part 103 and a fixed connecting seat 104. The vibration plate 201 is horizontally arranged between the receiving part 101 and the discharge part 102. The vibration motor 202 is arranged at the center position of the lower end of the vibration plate 201 by bolts. There is a discharge channel between the edge of the vibration plate 201 and the inner wall of the receiving part 101. The two ends of a plurality of compression springs 203 are respectively welded to the inner wall of the receiving part 101 and the side wall of the vibration plate 201. The plurality of compression springs 203 are evenly spaced at the four edges of the vibration plate 201.

[0028] The chip removal device of the CNC drilling and tapping machine in the present technical solution is mainly composed of a chip collection cover 1, a vibration cleaning mechanism 2, a debris conveying mechanism 3 and a debris collection box 4. A lifting support seat 5 is provided at the bottom of the chip collection cover 1, which can flexibly adjust the height of the chip collection cover 1 to adapt to the processing areas of different types of CNC drilling and tapping machines.

[0029] Chip collecting cover 1: The chip collecting cover 1 includes a material receiving portion 101, a material discharging portion 102, a material discharging portion 103 and a fixed connection seat 104.

[0030] Material receiving part 101: The material receiving part 101 is funnel-shaped, and its opening size is precisely adapted to the processing area of ​​the CNC drilling and tapping machine, and can efficiently collect the debris generated during the processing; the fixed connecting seat 104 is arranged in the material receiving part 101, and a certain gap is reserved between the edge of the fixed connecting seat 104 and the material receiving part 101. The gap design allows the debris to pass smoothly and avoids the debris accumulation at the connection part affecting the chip removal effect; a plurality of positioning bolts 105 are installed between the fixed connecting seat 104 and the material receiving part 101, and the positioning bolts 105 are provided with a telescopic spring 106. When the CNC drilling and tapping machine vibrates during the processing, the telescopic spring 106 can effectively buffer and reduce the influence of the vibration on the overall structure of the chip collection cover 1, thereby ensuring its stability.

[0031] The material discharge portion 102 is closely connected to the material receiving portion 101 and is used to guide the debris to slide down smoothly from the material receiving portion 101 .

[0032] Discharging section 103: A detachable structure is adopted between the discharging section 103 and the feeding section 102, so as to facilitate the disassembly operation during equipment maintenance or cleaning. The screw conveyor 301 is arranged in the discharging section 103, and a feeding port 1031 is arranged at one end of the discharging section 103 away from the feeding section 102, and the debris conveyed by the screw conveyor 301 is discharged from the feeding port 1031.

[0033] Fixed connecting seat 104: Fix the fixed connecting seat 104 to the lower end of the worktable of the CNC drilling and tapping machine by bolts to ensure that the chip cover 1 is firmly installed and does not occupy the surface space of the worktable, thereby preventing the chip cover 1 from shifting due to vibration or other external forces during processing, thereby avoiding debris splashing.

[0034] Vibration cleaning mechanism 2: The vibration cleaning mechanism 2 includes a vibration plate 201 and a vibration motor 202 which are arranged inside the chip collecting cover 1.

[0035] Vibration plate 201: The vibration plate 201 is horizontally arranged between the material receiving part 101 and the material discharging part 102. A material discharging channel is formed between the edge of the vibration plate 201 and the inner wall of the material receiving part 101, and the four corners of the vibration plate 201 are arc transitions, ensuring that the debris can pass smoothly and fall to the bottom of the chip collecting cover 1 to prevent chip jamming; the vibration plate 201 is connected to the inner wall of the chip collecting cover 1 through multiple compression springs 203 on all sides; the two ends of the multiple compression springs 203 are respectively welded to the inner wall of the material receiving part 101 and the side wall of the vibration plate 201, and are evenly spaced at the four edges of the vibration plate 201. This design enables the vibration plate 201 to vibrate evenly and stably under the drive of the vibration motor 202, and effectively removes debris adhering to the inner wall of the chip collecting cover 1 and the vibration plate 201.

[0036] Vibration motor 202: The vibration motor 202 is installed at the center of the lower end of the vibration plate 201 by bolts. After starting, it can drive the vibration plate 201 to vibrate at a high frequency, shake off the adhered debris, and improve the chip removal efficiency.

[0037] To ensure that the vibration plate 201 can stably bear the weight of itself and the vibration motor 202, a cylindrical helical compression spring 203 with a high elastic limit and a large load-bearing capacity is selected. The spring connection points are evenly arranged at intervals of 20-30 cm on the four edges of the vibration plate 201. The vibration plate 201 is made of a YZUL-10-4 model vibration motor 202 and an 8-10 mm thick Q235 steel plate. In a static state, when 8 springs are evenly arranged, each spring can share the weight of the vibration plate 201 and the vibration motor 202, and has sufficient load-bearing margin. The single-sided gap between the four edges of the vibration plate 201 and the inner wall of the chip collection cover 1 is greater than 25 mm to avoid affecting the free fall of debris, and the funnel-shaped chip collection cover 1 design will guide the debris to the bottom to further avoid the problem of chip jamming.

[0038] Chip conveying mechanism 3 : The chip conveying mechanism 3 includes a screw conveyor 301 and a drive motor 302 disposed at the bottom of the chip collecting cover 1 .

[0039] Screw conveyor 301: The feed port of the screw conveyor 301 is connected to the inside of the chip collecting cover 1. Its shell is made of stainless steel, which has good corrosion resistance and strength and can effectively resist the wear of debris. The internal spiral blades are connected to the output shaft of the drive motor 302 through a shaft.

[0040] The driving motor 302 is installed at one end of the outer shell of the screw conveyor 301 and connected to the shaft through a coupling. When the driving motor 302 is started, it drives the spiral blades to rotate and transports the debris that falls to the bottom of the chip collecting cover 1 to the debris collection box 4.

[0041] Debris collection box 4: The debris collection box 4 is located at the lower end of the debris conveying mechanism 3, adopts a movable design, and is equipped with rollers at the bottom, so that it is convenient to move it to a designated position for cleaning after it is full of debris. The operation is simple and convenient; the top opening of the debris collection box 4 is aligned with the discharge port 1031 at the lower end of the screw conveyor 301, so that it can accurately receive the conveyed debris.

[0042] Lifting support seat 5: The lifting support seat 5 includes a fixed bracket 501, and a plurality of adjustable support rods 502 are provided at the lower end of the fixed bracket 501. By adjusting the length of the adjustable support rods 502, the height of the chip cover 1 can be flexibly adjusted to adapt to CNC drilling and tapping machines with different height requirements, thereby enhancing the versatility of the device. The fixed bracket 501 is arranged at the bottom of the chip cover 1, and is fixedly connected to the bottom of the chip cover 1 by bolts and other connecting parts to ensure stable support.

[0043] In this embodiment, the specific operation steps are as follows:

[0044] According to the size and height of the workbench of the CNC drilling and tapping machine, adjust the adjustable support rod 502 of the lifting support seat 5, adjust the chip collection cover 1 to the appropriate height, and then use bolts to fix the fixed connecting seat 104 to the bottom of the workbench of the CNC drilling and tapping machine to ensure that the chip collection cover 1 is firmly installed and well sealed.

[0045] When the CNC drilling and tapping machine is processing, the vibration motor 202 and the drive motor 302 are started, and the debris generated by the processing first falls into the receiving part 101 of the chip collecting cover 1. Some of the debris falls to the bottom of the chip collecting cover 1 directly through the discharge channel between the edge of the vibration plate 201 and the inner wall of the receiving part 101 due to gravity, and some of the debris adhering to the inner wall of the receiving part 101 and the vibration plate 201 falls under the high-frequency vibration of the vibration plate 201 driven by the vibration motor 202.

[0046] The debris dropped to the bottom of the debris collecting cover 1 is conveyed to the debris collecting box 4 through the discharge port 1031 of the discharge portion 103 under the rotation of the spiral blades of the screw conveyor 301 .

[0047] When the debris collection box 4 is full of debris, it is moved to a designated position by rollers for cleaning, and then put back to its original position to continue working. If the inside of the chip collection cover 1 needs to be maintained or cleaned during the operation of the equipment, the discharge part 103 and the discharge part 102 can be separated for easy operation.

[0048] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
