Description

Technical Field

[0001] This utility model belongs to the field of machining technology, and in particular relates to a chip collection device for a drilling machine. Background Technology

[0002] The roller press sleeve drilling machine is a high-efficiency CNC drilling machine. During continuous operation, it requires constant high-pressure cooling water and generates a continuous stream of iron filings. These iron filings are in the form of iron powder, which adheres to the cooling water and remains on the roller sleeve surface for a long time, making them difficult to clean. This is detrimental to processing quality, safety, and environmental protection.

[0003] The current method involves stopping the machine tool periodically for manual cleaning and removal. This method is rudimentary and inevitably impacts production efficiency. Furthermore, in winter, the mixture of cooling water and metal filings splashes onto other parts of the machine tool. For example, if it splashes onto the tool setter, it quickly freezes, causing the tool setter to malfunction and severely affecting the normal operation of the machine tool. Therefore, the mixture of cooling water and metal filings not only directly negatively impacts machine tool production efficiency but also has significant indirect effects on quality, safety, and environmental protection. Summary of the Invention

[0004] To address the problems existing in the prior art, this utility model provides a chip collection device for a drilling machine. It effectively captures the chips generated during drilling, preventing chip splattering and thus improving chip collection efficiency, solving the problem of chip and cooling water mixture retention. The retractable protective mechanism allows it to adapt to the processing of workpieces of different specifications, improving the overall versatility of the structure.

[0005] This utility model is implemented as follows: a chip collection device for a drilling machine, the drilling machine includes a spindle box, on which a machining spindle and a coolant nozzle are provided. A protective mechanism is provided on the spindle box located on the side of the machining spindle. The machining spindle and the coolant nozzle are placed inside the protective mechanism. The protective mechanism can extend and retract along the axial direction of the machining spindle. The extended end of the protective mechanism is in contact with the surface of the workpiece to form a semi-enclosed collection space with an open bottom.

[0006] Furthermore, the protective mechanism includes an outer protective cover mounted on the spindle box. A linear guide assembly is mounted on the side plate of the outer protective cover, and an inner protective cover is mounted inside the outer protective cover. The side plate of the inner protective cover is connected to a slider in the linear guide assembly. A push-out cylinder is mounted on the top plate of the outer protective cover, and the piston rod of the push-out cylinder is connected to the inner protective cover, enabling the inner protective cover to move axially along the machining spindle. The inner protective cover is connected to the outer protective cover via the linear guide assembly, allowing the inner protective cover to move smoothly along the machining spindle axis, closely conforming to workpieces of different sizes and shapes, thereby achieving axial extension and retraction of the protective mechanism. The layered design of the outer and inner protective covers improves the strength and stability of the device, and the integrated design of the linear guide assembly and the push-out cylinder makes the entire protective mechanism more compact and efficient, reducing unnecessary space occupation and energy consumption.

[0007] Furthermore, the extended end of the protective mechanism is equipped with a brush. The brush can closely conform to the workpiece surface, and even when there are slight unevenness or curvature on the workpiece surface, it can maintain good contact due to its flexibility, thereby effectively reducing the leakage of iron filings and coolant, and further improving the sealing of the semi-enclosed collection space; the brush bristles can sweep across the workpiece surface, scraping the fine iron filings and coolant mixture adhering to the workpiece more thoroughly into the collection space, avoiding iron filings residue, and significantly improving the iron filings collection efficiency; the soft characteristics of the brush will not cause scratches or damage to the workpiece surface when in contact with the workpiece, which helps to protect the quality and integrity of the workpiece surface.

[0008] Furthermore, both side plates of the inner protective cover are hinged with guide plates at their lower ends, and these guide plates are deflected toward the machining spindle. The guide plates allow the coolant and metal scrap mixture, after being collected by the inner protective cover, to flow smoothly along the guide plates to the designated collection area or discharge port. This guides the mixture of metal scrap and coolant along a specific path, reducing unnecessary waste and loss, and improving the efficiency of the entire collection system.

[0009] Furthermore, both the outer and inner protective covers are made of transparent sheet material. This transparency allows operators to clearly observe the entire drilling process without interrupting the machining operation. This helps in the timely detection and handling of issues during machining, such as the spindle's operation, the spraying of cooling water, and the collection of cooling water and metal chips, thereby ensuring machining quality and safety.

[0010] Furthermore, the top plate of the outer protective cover is also equipped with a solenoid valve for controlling the propulsion cylinder.

[0011] The advantages and technical effects of this utility model are as follows: By adopting the above-mentioned technical solution, iron filings generated during drilling are effectively captured, preventing iron filings from splashing and thus improving the collection efficiency of iron filings and solving the problem of iron filings and cooling water mixture retention. The retractable protective mechanism can adapt to the processing of workpieces of different specifications, improving the versatility of the overall structure. With the machining spindle and coolant nozzles placed inside the protective mechanism, the rotation of the machining spindle, the spraying of cooling water, and the collection of iron filings can be carried out simultaneously. This does not affect the machining of the spindle and provides close-range protection for the cooling water and iron filings. Attached Figure Description

[0019] Furthermore, guide plates 8 are hinged to the lower ends of both side plates of the inner protective cover 4, and the guide plates 8 are deflected toward the machining spindle 2. The guide plates 8 allow the coolant and iron filings mixture, after being collected by the inner protective cover 4, to flow smoothly along the guide plates 8 to the designated collection area or discharge port, guiding the iron filings and coolant mixture along a specific path, reducing unnecessary waste and loss, and improving the efficiency of the entire collection system.

[0020] Furthermore, both the outer protective cover 3 and the inner protective cover 4 are made of transparent sheet material.

[0021] The advantages and technical effects of this utility model are as follows: By adopting the above-mentioned technical solution, iron filings generated during drilling are effectively captured, preventing iron filings from splashing and thus improving the collection efficiency of iron filings and solving the problem of iron filings and cooling water mixture retention.
