Description

Technical Field

[0001] This utility model relates to the field of automated debris removal, and in particular to a debris removal device for cylinder drilling. Background Technology

[0002] Drilling, as one of the fundamental processes in machining, removes excess material through the relative movement of a drill bit and a workpiece, creating a hole structure that meets design requirements. In precision equipment such as engines and compressors, the cylinder, as a core power transmission component, directly affects the efficiency and lifespan of the equipment due to the machining quality of its surface-mounted precision hole system, including oil passages and cooling holes. With the increasing demands for machining accuracy and efficiency in the manufacturing industry, traditional manual drilling has been gradually replaced by automated CNC drilling equipment.

[0003] Existing cylinder drilling equipment typically employs multi-axis CNC machine tools. A fixture fixes the cylinder blank to the worktable, and a high-speed rotating drill bit feeds along a predetermined trajectory to complete the hole machining. Such equipment can achieve functions such as hole positioning, drilling parameter adjustment, and automatic tool changing through program control. However, the generation and removal of metal chips during drilling remains a critical issue affecting process stability. Due to the complex structure and uneven wall thickness of the cylinder, strip-shaped, coil-shaped, or granular chips generated during drill cutting randomly scatter across the worktable, guide rails, and chip collection device.

[0004] While randomly falling debris may not directly interfere with the drilling process, debris scattered inside the equipment may intrude into precision transmission components such as guide rails and lead screws, causing equipment wear or malfunctions. Subsequent manual cleaning is required, increasing non-processing time and reducing production efficiency. In addition, as a high-precision component, if debris remaining in the boreholes of the cylinder is not thoroughly removed, it may lead to decreased sealing performance after assembly or accelerated wear during operation. Utility Model Content

[0005] The technical problem to be solved by this invention is debris contamination and manual cleaning. It provides a debris cleaning device for cylinder drilling, which aims to solve the above problems.

The base is installed in a CNC machine tool. A cylinder is installed at the rear end of the base. A placement plate is slidably connected to the front end of the base. A collection frame is placed on the top of the placement plate. The piston rod of the cylinder faces the front end and is connected to the mounting block. A guide rod is connected to the front side of the cylinder. The mounting block is slidably connected to the guide rod. An electromagnet is installed on the mounting block. A push switch is sleeved at the rear end of the guide rod. The mounting block and the push switch are pressed together. The push switch is wired to the electromagnet. A material leveling mechanism for shaking the placement plate and the collection frame is provided at the front end of the base.

[0007] A further preferred embodiment of this utility model is as follows: the material feeding mechanism includes a motor, a reciprocating lead screw, and a pulley assembly. The motor is installed on the right side of the base, and two reciprocating lead screws are rotatably connected inside the base. The end of one of the reciprocating lead screws is fixedly connected to the output shaft of the motor. The reciprocating lead screws are threadedly connected to the front and rear ends of the placement plate, respectively. The left ends of the two reciprocating lead screws are connected to a pulley assembly, which consists of two pulleys and a transmission belt. The pulleys are connected to the reciprocating lead screws, and the motor is wiredly connected to the push switch.

[0008] A further preferred embodiment of this utility model is: it also includes bolts and nuts, with nuts connected to both the left and right ends of the material collection frame, and the bolts are threadedly connected to the left and right ends of the top of the placement plate, and the bolts and nuts are threadedly connected.

[0014] Compared with existing technologies, the advantages of this invention are as follows: The mounting block is driven by a cylinder to reciprocate along the guide rod.

When the mounting block retracts, its bottom surface contacts the inclined surface of the scraper, which forcibly peels off the debris and guides it into the collection frame, achieving active adsorption and release of debris. A motor drives a reciprocating screw to rotate, combined with a pulley system, to achieve horizontal reciprocating motion of the placement plate. The bidirectional thread of the reciprocating screw drives the placement plate to cause the collection frame to shake regularly, ensuring even distribution of debris, preventing debris from accumulating and hardening within the collection frame, improving storage space utilization, and facilitating subsequent sorting and recycling.

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0022] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0023] This embodiment mainly describes the structure of the debris cleaning device, as follows:

[0024] A debris removal device for cylinder drilling, such as Figures 1-4 As shown, the system includes a base 1, a cylinder 2, a mounting block 3, an electromagnet 4, a push switch 5, a guide rod 6, a placement plate 7, a collection frame 11, and a material leveling mechanism. The base 1 is installed inside the CNC machine tool. The cylinder 2 is installed at the rear end of the base 1, and the placement plate 7 is slidably connected to the front end of the base 1. The placement plate 7 has a groove in the middle for placement, and the collection frame 11 is located in the groove. The collection frame 11 is placed on top of the placement plate 7. The piston rod of the cylinder 2 faces the front end and is connected to the mounting block 3. The guide rod 6 is connected to the front side of the cylinder 2. The mounting block 3 is slidably connected to the guide rod 6, and the electromagnet 4 is installed on the mounting block 3. The push switch 5 is sleeved at the rear end of the guide rod 6. The mounting block 3 and the push switch 5 are pressed together. The push switch 5 is wired to the electromagnet 4. The synergistic action of the electromagnet 4 and the scraper 16 realizes the automatic process of active adsorption-scraping-collection of debris, avoiding downtime for manual cleaning and improving processing continuity. The front end of the base 1 is equipped with a material leveling mechanism for shaking the placement plate 7 and the collection frame 11.

[0025] like Figure 3 and Figure 4 As shown, the material leveling mechanism includes a motor 8, a reciprocating lead screw 9, and a pulley assembly 10. The motor 8 is installed on the right side of the base 1. Two reciprocating lead screws 9 are rotatably connected inside the base 1. The end of one of the reciprocating lead screws 9 is fixedly connected to the output shaft of the motor 8. The reciprocating lead screws 9 are threaded to the front and rear ends of the placement plate 7, respectively. Each reciprocating lead screw 9 is provided with a bidirectional thread for support and has two connections to both ends of the placement plate 7. The left ends of the two reciprocating lead screws 9 are connected to the pulley assembly 10. The pulley assembly 10 consists of two pulleys and a transmission belt. The pulleys are connected to the reciprocating lead screws 9. The motor 8 is wired to the push switch 5. Through reciprocating motion, the debris is automatically layered and evenly distributed, preventing debris from accumulating and caking in the collection frame 11 and improving the utilization rate of storage space.

[0026] like Figure 1 and Figure 2 As shown, it also includes bolts 12 and nuts 13. Nuts 13 are connected to both the left and right ends of the collection frame 11. Bolts 12 are threaded to the top left and right ends of the placement plate 7, and bolts 12 and nuts 13 are threaded together. The quick disassembly and assembly of bolts 12 and nuts 13 simplifies the replacement process of collection frame 11.

[0027] like Figure 2 As shown, it also includes handles 14, with handles 14 connected to the top of both the left and right sides of the material collection frame 11.

[0028] like Figure 1As shown, it also includes an isolation filter plate 15. The isolation filter plate 15 is slidably connected inside the collection frame 11. The isolation filter plate 15 is suspended in the middle of the collection frame 11 by bending plates at both ends. The physical isolation structure avoids the mixing of debris of different particle sizes and improves the purity of the recovered debris.

[0029] like Figure 1 and Figure 4 As shown, it also includes a scraper 16. The scraper 16 is connected to the top of the base 1. The scraper 16 is slidably connected to the bottom side of the mounting block 3. The front side of the scraper 16 is provided with an inclined surface. The inclined surface structure reduces the scraping resistance and improves the chip removal efficiency.

[0030] like Figure 1 As shown, the bolt 12 has several anti-slip grooves 17 at its front end. The anti-slip grooves 17 increase the coefficient of friction and improve the reliability of disassembly.

[0031] When the CNC machine tool performs drilling operations with cylinder 2, the metal chips generated by the drill bit naturally fall to the bottom of the working area. At this time, the piston rod of cylinder 2 extends forward, pushing the mounting block 3 to move horizontally along the guide rod 6 towards the bottom of the drilling position. When the mounting block 3 is completely disengaged from the push switch 5 at the rear end of the guide rod 6, the push switch 5 triggers the timing function. After the preset time is reached, the power to the electromagnet 4 is turned on. The electromagnet 4 generates a strong magnetic field, which quickly attracts the chips from the bottom of the worktable and the drilling area to the bottom surface of the mounting block 3, effectively reducing the random scattering of chips on the worktable surface.

[0032] After the debris is adsorbed, the piston rod of cylinder 2 retracts in the reverse direction, causing the mounting block 3 to smoothly return to its initial position along the guide rod 6. During the retraction of the mounting block 3, its bottom surface slides into contact with the scraper 16 fixed to the top of the base 1. The inclined structure on the front side of the scraper 16 efficiently scrapes the bottom surface of the mounting block 3, completely peeling off the adsorbed debris and guiding it into the collection frame 11 below. When the mounting block 3 retracts to its initial position and re-engages with the press switch 5, the press switch 5 immediately cuts off the power to the electromagnet 4, and the magnetic field disappears. At this time, any trace debris that may remain on the bottom surface of the mounting block 3 will naturally fall off due to the loss of magnetic force. Some of the adhered debris will be completely removed by the continuous action of the scraper 16 when the mounting block 3 is pushed out again.

[0033] To prevent debris accumulation in the collection frame 11 from affecting collection efficiency, the motor 8 is started by pressing the switch 5 after the mounting block 3 completes one full extension and retraction cycle. The motor 8 drives two reciprocating screws 9 to rotate synchronously via the pulley assembly 10. The bidirectional threads on the surface of the reciprocating screws 9 drive the placement plate 7 to reciprocate horizontally, causing the collection frame 11 to vibrate rhythmically. During this vibration, the slidably connected isolation filter plate 15 within the collection frame 11 layers the debris through its own gravity and vibration. Smaller debris passes through the mesh of the isolation filter plate 15 and falls to the bottom of the collection frame 11, while larger debris is retained on the filter plate surface, achieving graded storage of the debris. The motor 8 automatically stops after a preset running time, the reciprocating screws 9 stop rotating, and the placement plate 7 returns to a stationary state.

[0034] When the debris accumulates to a certain amount in the collection frame 11, the operator first loosens the bolts 12 on the top left and right sides of the placement plate 7. The anti-slip grooves 17 at the front end of the bolts 12 effectively increase hand friction, ensuring convenient disassembly. After the bolts 12 are completely disengaged from the nuts 13 on the side of the collection frame 11, the operator holds the handles 14 on both sides of the collection frame 11 and vertically removes it from the groove of the placement plate 7. Then, the isolation filter plate 15 is horizontally pulled out from the collection frame 11, and the debris on the surface of the filter plate and the bottom of the frame are sorted and recycled. After cleaning, the isolation filter plate 15 is slid back into the middle of the collection frame 11 for suspension and positioning. The bottom of the collection frame 11 is aligned with the groove of the placement plate 7 and placed vertically. The bolts 12 are tightened to ensure complete engagement with the nuts 13, completing the quick replacement and fixing of the collection frame 11.
