Description

Technical Field

[0001] This utility model relates to the field of drilling technology, specifically an inverted U-type drilling machine. Background Technology

[0002] In modern machining, drilling machines, as an important machine tool, play an indispensable role in the manufacturing process. However, with the development of industrial technology and the increasing demands for product precision, traditional drilling machines have gradually revealed some limitations and shortcomings in their use. Firstly, traditional drilling operations typically require manually setting positioning holes beforehand to prevent U-drill slippage. This method is not only inefficient but also prone to significant human error, making it difficult to guarantee drilling accuracy. Especially in mass production, manually positioning each workpiece is not only time-consuming but also increases operational complexity.

[0003] Furthermore, traditional drilling machine designs often lack consideration for stability during the drilling process. In practical applications, the impact force at the moment of contact between the U-drill and the workpiece may cause the U-drill to deviate from its intended path, thus affecting the drilling quality. This instability is particularly pronounced for workpieces with a small number of holes but extremely high precision requirements, significantly limiting production efficiency. Simultaneously, traditional drilling machines have unfriendly interfaces and lack effective safety measures, posing potential safety hazards to operators and making it difficult to observe the drilling process. Therefore, this invention proposes an inverted U-drill machine. Utility Model Content
