Embodiment Construction

[0016] Below, the present invention will be further described with reference to the accompanying drawings and examples. The following examples are illustrative, not restrictive, and the protection scope of the present invention cannot be limited by the following examples.

[0017] A drilling pneumatic tool with the function of dynamic collection of negative pressure drill cuttings. As shown in the accompanying drawings of this embodiment, the drilling pneumatic tool is a pneumatic hand drill, and the air power is provided by an air source 9. At the head of the pneumatic hand drill 8 A drill bit 2 is installed in the center of the front end. The innovation of the present invention is: a fixed sleeve 5 is coaxially fixed at the front end of the drill body of the pneumatic hand drill, and a coaxial sliding sleeve 4 that can move axially is installed on the outer circle of the fixed sleeve. A transparent suction cover 1 made of plexiglass (or other transparent materials) is coaxia...

Abstract

The invention relates to a drilling pneumatic tool with negative-pressure drillings dynamic collection function. A fixed sleeve is coaxially fixed on the front end of the drilling pneumatic tool; the excircle of the fixed sleeve is provided with a coaxial sliding sleeve which can move axially; a transparent sucking cover is coaxially fixed on the front end of the coaxial sliding sleeve; the center of the front end surface of the transparent sucking cover is provided with a center hole which protrudes from a bit, and the side edge of the transparent sucking cover is provided with a drillings collecting bag which is communicated with a negative-pressure vacuum generator. The drilling pneumatic tool can effectively prevent the drillings from splattering outside in the drilling process, reduces the subsequent cleaning procedure and difficulty and greatly improve the work efficiency and the work effect. The work position of the bit can be adjusted and controlled in real time through monitoring the work situation of the bit through the transparent sucking cover in the drilling process. The transparent sucking cover and the vacuum generator which are arranged on the drilling pneumatic tool do not need to do any change to the body of the drilling pneumatic tool and can not cause any influence to the performance of the drilling pneumatic tool.

Description

technical field [0001] The invention relates to a dynamic collection device for drilling chips, in particular to a drilling pneumatic tool with the function of dynamic collection of negative pressure drilling chips. Background technique [0002] After the aircraft has been used for a certain period of time, its structure will be damaged to a certain extent due to corrosion or stress. In the process of repairing the damaged part, some parts need to be drilled; when drilling in the cabin, the drill Chips are often flying around and scattered on the ground. It is very difficult to clean up the fine debris. If the cleaning is not clean, the remaining debris will bring hidden dangers to flight safety, and even lead to safety accidents in severe cases. Therefore, all aircraft maintenance companies attach great importance to this work, and the problem of debris cleaning has become a technical problem that plagues aircraft maintenance companies. [0003] The existing and often used...
