Description

Technical Field

[0001] This invention relates to the field of machining technology, and in particular to a device for machining mounting holes in a reducer box cover. Background Technology

[0002] Machining the mounting holes for the gearbox cover is a critical step in gearbox production, as its precision directly affects the seal and assembly quality of the gearbox housing. In recent years, significant progress has been made in the development of gearbox cover mounting hole machining equipment, primarily focusing on improving machining efficiency and hole position accuracy, as well as automating operations to reduce human error. Such equipment typically meets basic machining requirements and ensures a certain level of hole position accuracy and operational safety through chip collection structures.

[0003] Chinese Patent (Announcement No. CN211588613U) discloses a "processing device for mounting holes in a reducer box cover". This processing device includes a bucket-shaped box with a dust extraction pipe installed at the bottom. A bidirectional threaded rod is rotatably mounted on the inner side of the top of the box, and a first sliding rod is fixed to the inner wall of the box below it. A T-shaped placement platform is located in the middle of the bidirectional threaded rod and the first sliding rod. The T-shaped placement platform is fixed to the first sliding rod and has a through hole through which the bidirectional threaded rod passes. This processing device, through the above structure, can realize the placement, clamping, and drilling of the cover plate, and uses the bucket-shaped box to collect the debris generated during drilling, preventing debris from scattering and splashing. This patent solution has a relatively simple structure and is relatively convenient to operate.

[0004] However, the aforementioned existing technical solutions still have significant shortcomings in practical applications: 1. Lack of effective solid-liquid separation function: The device only collects debris through a hopper-shaped box and dust discharge pipe, but it cannot effectively separate the metal debris generated during processing from the cutting coolant used. The solid (debris) and liquid (cutting fluid) mixture generated during processing is either directly discharged or remains mixed after collection, making the subsequent cleaning and separation process extremely cumbersome. It requires a lot of manual sorting, significantly increasing additional labor costs and production downtime.

[0005] 2. Difficult and costly resource recycling: The solid-liquid mixture makes it difficult to recycle and reuse valuable metal scrap and waste cutting fluid. Metal scrap is difficult to recycle effectively, resulting in resource waste. Waste cutting fluid mixed with a large amount of solid impurities also greatly increases the difficulty and cost of subsequent purification or harmless treatment. This not only increases the overall material cost, but also increases the burden of environmental treatment.

[0006] 3. Potential environmental and maintenance issues: Direct discharge of unseparated mixed waste liquid can easily cause environmental pollution; if stored, it poses a risk of leakage and occupies a large space. In addition, long-term accumulation of mixed waste liquid may corrode equipment or clog drainage pipes, affecting the long-term reliability of equipment operation and increasing maintenance costs.

[0007] Therefore, in order to address the shortcomings of existing gearbox cover plate mounting hole processing devices, it is necessary to focus on solving the technical problem that they cannot achieve efficient solid-liquid separation of processing waste (chips and cutting fluid) in order to reduce labor costs, improve resource recovery rate, reduce environmental pollution risks and ensure stable equipment operation.
