Numerical control drilling machine with shock absorption function and high safety

Abstract

The invention relates to a numerical control drilling machine with a shock absorption function and high safety. The numerical control drilling machine with the shock absorption function and high safety comprises a base, a main body, a shock absorption mechanism, a lifting plate, a drive motor, a drilling rod, a protection mechanism and two lifting devices. The protection mechanism comprises a protection plate and two connecting assemblies; each connecting assembly comprises a connecting rod, a limiting plate and a first spring; the shock absorption mechanism comprises an air bag, a collectingassembly and two shock absorption assemblies; and each shock absorption assembly comprises a first bearing, a screw rod, a ball screw bearing, a torsion spring and a transmission unit. According to the numerical control drilling machine with the shock absorption function and high safety, chippings can be prevented from being scattered, so that the safety of the equipment is improved; and through the shock absorption mechanism, the effects on shock-absorbing and buffering the equipment are achieved, and the occurrence of the phenomenon that the punching accuracy is affected due to excessive shaking of the equipment is avoided.

Description

technical field [0001] The invention relates to the field of numerically controlled machine tools, in particular to a highly safe numerically controlled drilling machine with a vibration damping function. Background technique [0002] CNC drilling machines are mainly used for drilling, reaming, reaming, tapping and other processing. It is a numerically controlled hole processing machine tool mainly for drilling. Due to the development of machining centers, most CNC drilling machines have been replaced by machining centers. In the automobile, locomotive, shipbuilding, aerospace, engineering machinery industries; especially for the drilling of various large-scale parts such as ultra-long stacked plates, longitudinal beams, structural steel, and tubular parts, it is the first choice. [0003] Existing CNC drilling machines will vibrate when performing drilling work, causing the equipment to shake up and down, thus affecting the accuracy of drilling. Not only that, but the exis...

Problems solved by technology

[0003] Existing CNC drilling machines will vibrate when performing drilling work, causing the equipment to shake up and down, thus affecting the accuracy of drilling. Not only that, but the existing CNC machine tools produce more debris when drilling, and some debris is easy to Splashing around increases the probability of debris splashing on the user, poses a threat to the personal safety of the user, and reduces the practicability of the existing CNC machine tools
