Description

A high-strength drilling machine shock-absorbing base

technical field

The utility model relates to the technical field of mechanical processing, in particular to a shock-absorbing base of a high-strength drilling machine.

Background technique

With the development of social economy, mechanical equipment is used instead of manual production, which improves the efficiency of work and reduces the intensity of manual labor, such as drilling machines. Drilling machines are machine tools that mainly use drill bits to process holes on workpieces. Usually, the drill bit rotates as the main movement. , The axial movement of the drill bit is the feed movement. The structure of the drilling machine is simple. It can drill through holes and blind holes, replace special tools, and can be expanded, countersinked, reamed or tapped.

The drilling machine will have very strong vibration during processing. The severe vibration will reduce the processing accuracy, processing stability and processing safety when the drilling machine is processing the workpiece. It will cause damage to the drilling machine, and the vibration will cause a lot of noise, making the sound in the processing workshop noisy. At present, the shock-absorbing base of many drilling machines is simply installed with a shock-absorbing rod to damp the drilling machine in the vertical direction, but there will also be vibrations in other directions when the drill bit rotates, and the shock-absorbing effect is not good.
