Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile parts processing, more specifically, it relates to a drilling device for automobile parts processing. BACKGROUND

[0002] In the field of automobile parts processing, the existing drilling device has serious technical defects and safety hazards in dust treatment, which not only affects the processing efficiency, but also seriously threatens the health and safety of the operators. Specifically, these technical problems mainly manifest in the following key aspects:

[0003] Firstly, during the drilling process of automobile parts, the cutting of metal materials produces a large amount of fine metal dust particles. These metal dusts, due to their fine texture, are easily in a suspended state in the workshop air and widely spread in the entire working space under the action of air flow. Long-term work of workers in such an environment inevitably leads to continuous inhalation of these metal dusts. Once these tiny metal particles enter the human respiratory system, they will gradually accumulate in the lung tissue. Due to the difficulty of the human body's own cleaning mechanism to effectively handle these metal foreign bodies, long-term accumulation will lead to serious occupational diseases, causing irreversible damage to the health of workers.

[0004] Secondly, although most of the drilling equipment on the market is equipped with a basic dust removal system, which usually includes a dust suction pump, a pipeline and a chip collection box, etc. basic components, trying to collect metal dust through this simple suction system. However, these traditional dust removal devices have obvious limitations in design, especially in the simplicity of the internal structure of the pipeline. The most prominent problem is that these systems cannot flexibly adjust the air suction speed according to different working condition requirements and processing parameters. This fixed air suction mode not only reduces the dust removal efficiency, but also may affect the processing quality in some cases due to the mismatch between the air suction speed and the actual demand. Overly strong airflow affects drilling precision, and insufficient air suction leads to dust residue.

[0005] More importantly, some improved equipment on the market may increase the air suction speed adjustment function, trying to improve the adaptability of the system through this improvement. However, these adjustment devices still have serious defects in structural design. The main problem is that these simple adjustment structures are prone to stability problems during actual use. Specifically, when high-speed airflow continuously impacts the inner wall of the pipeline, combined with the continuous vibration generated during equipment operation, it is easy to cause the adjustment device to loosen. This lack of structural stability directly affects the stability of the airflow speed, making it difficult to maintain the carefully adjusted gas flow rate, which seriously affects the reliability and sustainability of the dust removal effect. This technical defect not only reduces the practicality of the equipment, but also may lead to significant fluctuations in the dust removal effect, affecting the stability and controllability of the entire processing process.
