Technical Field

The utility model relates to the technical field of drilling, in particular to a drilling device for disc parts.

Background technique

Bench drilling machine, also known as bench drill, refers to a small drilling machine that can be placed on a workbench with a vertical spindle. It is widely used in the field of mechanical processing to perform drilling processing on workpieces of various shapes.

In order to improve the applicability of drilling holes in workpieces, the prior art has made many improvements to workpiece drilling devices. For example, the patent with patent publication number CN217315944U discloses an efficient punching device for the production of mechanical parts, including an assembly chassis, a supporting device is provided on the lower side of the assembly chassis, the supporting rod of the supporting device is connected to the bottom plate of the assembly chassis, a buffer disc is provided on the lower side of the support rod, an anti-slip strip is bonded to the lower side of the buffer disc, a lifting platform is provided on the upper surface of the assembly chassis, a drilling platform is provided on the lower side of the assembly plate of the lifting platform, an elastic fixing device is provided under the drilling platform, and a lifting fixing device is provided under the elastic plate of the elastic fixing device. Since the drill bit of the punching device of the utility model is threadedly fixed on the rotating motor of the punching device, it is convenient for the staff to disassemble and install drill bits of different specifications, and the buffer round block is bonded to the lower side of the elastic plate of the fixing device, which can effectively avoid damage to the parts due to excessive clamping force.
