Description

Technical Field

[0001] The utility model relates to the technical field of drilling devices, in particular to a steel plate drilling device. Background Art

[0002] Drilling devices are tools or equipment for making holes on the surface of various materials. They are widely used in the fields of construction, engineering machinery, rail transportation, shipbuilding, aerospace, etc. Drilling operations are an indispensable part of many manufacturing and assembly processes, and are particularly important for production operations that require precision and efficiency.

[0003] In the existing technology, the application of drilling equipment is quite mature, but there are still some technical challenges when it comes to drilling operations of large-sized and thin plate materials. For example, large thin steel plates are easy to deform during operation due to their large area and thin thickness. This deformation not only makes it difficult to fix the plate stably on the traditional drilling machine or fixed drilling machine equipment, but also may affect the accuracy and quality of the drilling. Therefore, when drilling with a traditional fixed drilling machine, the processing cost and difficulty of large thin plate materials are high.

[0004] In addition, although handheld drilling equipment (such as pistol drills) provides flexibility in operation, it is easy to cause drilling deviation or slanted holes when processing larger or thinner steel plates due to the lack of stable support. This not only affects the appearance and performance of the product, but may also cause damage to the material, increase production resource waste and repair costs.

[0005] Therefore, those skilled in the art have proposed a drilling device for thin steel plates that is easy to control and operate. Utility Model Content
