Description

Technical Field

[0001] The present application relates to the technical field of multi-head drilling machines, and in particular to an adjustable multi-head drilling machine. Background Art

[0002] A drilling machine is a mechanical device used to drill holes in a workpiece. It creates a hole by rotating the cutting tool (drill bit) on the surface of the workpiece. A multi-head drilling machine is a mechanical device used to drill multiple holes at the same time. It usually consists of a spindle and multiple drilling heads arranged in parallel. Multi-head drilling machines are widely used in woodworking, metal processing, plastic processing and other fields.

[0003] In actual use, the positions of the multiple drill bits on the existing multi-head drilling machines are mostly fixed. The fixed positions of the drill bits mean that the multi-head drilling machines can only adapt to workpieces with specific spacings and cannot flexibly adapt to drilling requirements of different spacings, resulting in the need for additional equipment when processing workpieces of different sizes, which limits the scope of application and increases operating costs.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.
