Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, and in particular to a high-efficiency drilling machine for PVC pipes. Background Technology

[0002] In the production of PVC pipes, it is often necessary to drill holes in multiple locations with high precision on the pipe sidewalls to meet the installation requirements of drainage, ventilation, and other systems. Traditional drilling equipment has the following limitations: 1. Low efficiency: The single-drill-bit processing mode requires frequent adjustments to the pipe position, which is time-consuming and labor-intensive, making it difficult to meet the needs of mass production; 2. Insufficient positioning accuracy: The pipe is prone to displacement or vibration during transportation, resulting in drilling position deviations and a high scrap rate; 3. Poor adaptability: Fixed clamps are difficult to adapt to PVC pipes of different diameters, and manual adjustment of the equipment is required when switching processing specifications; 4. Defective waste disposal: Traditional equipment lacks an effective device for collecting drill cuttings and coolant, resulting in a dirty working environment and affecting the lifespan of the equipment.

[0003] While some automated drilling equipment exists in the existing technology (such as patent CN220761054 U), its guiding system is mostly based on single-dimensional constraints, which cannot simultaneously control the lateral alignment and longitudinal positioning of the pipeline. Furthermore, the drilling unit layout is simple, making it difficult to achieve simultaneous processing of multiple holes. In addition, traditional chuck structures are complex and time-consuming to adjust, making it difficult to quickly adapt to the production needs of multi-specification pipelines.
