Abstract
The invention discloses an airflow cylinder of an airflow-driven drilling tool, which comprises an inner airflow cylinder and an outer airflow cylinder which is sleeved outside the inner airflow cylinder and has the same height, wherein the outer airflow cylinder is provided with a first air inlet hole and a second air inlet hole, the side wall of the inner airflow cylinder is provided with a plurality of ventilation holes, and the inner airflow cylinder is internally provided with a helical blade. The technical scheme of the invention can provide sufficient power for the rotation of the helical blade and ensure that the drill bit can smoothly reach a preset position.
Description
Technical field
The present invention relates to machine drilling apparatus field, especially relate to a kind of air-flow cylinder of air stream drives formula boring bar tool.
Background technology
In the processing and manufacturing process of component of machine, usually need to carry out horizontal or longitudinal boring process to parts, have through hole or blind hole point.Along with the requirement of bore process is more and more higher, give birth to the instrument being much specifically designed to machine drilling because of fortune, such as hand boring bar tool, mechanically driver type boring bar tool, fluid pressure type boring bar tool and pneumatic boring bar tool etc.For each own different advantage place of different boring bar tools, but when to when pitch-row is comparatively dark or material is the parts machining of stickiness, drill bit can be stuck in boring and be not easy taking-up.Now, Pneumatic drilling instrument just tool have great advantage.Although existing pneumatic type boring bar tool can solve the problem that drill bit is not easy to block, the air pressure that usually there is boring bar tool is not enough, causes drill bit cannot arrive predetermined bore position problem.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the object of the invention is the air-flow cylinder proposing a kind of air stream drives formula boring bar tool.
As the first embodiment, the invention provides a kind of air-flow cylinder of air stream drives formula boring bar tool, described air-flow cylinder comprises internal layer air-flow cylinder and is socketed on its outside and highly equal outer gas flow cylinder, described outer gas flow cylinder is provided with the first air admission hole and the second air admission hole, the sidewall of described internal layer air-flow cylinder is provided with multiple air-vent, is provided with helical blade in described internal layer air-flow cylinder.
On the basis of the first embodiment, as the second embodiment, described first air admission hole and described second air inlet position are separately installed with air-flow filter bowl with matching.
On the basis of the first embodiment, as the third embodiment, described first air admission hole and described second air admission hole are respectively equipped with barometric damper.
The air-flow cylinder of a kind of air stream drives formula boring bar tool provided by the present invention, by arranging internal layer air-flow cylinder and outer gas flow cylinder socket join structure, enough air pressure can be stored rotate for driving the helical blade in internal layer air-flow cylinder in outer gas flow cylinder, and be provided with at the sidewall of internal layer air-flow cylinder the contact area that air-vent increases air-flow and helical blade, accelerate it and rotate; The air-flow in high pressure gas can be prevented to be mixed into impurity by arranging air-flow filter screen, wearing and tearing are caused to the parts in internal layer air-flow cylinder; By arranging barometric damper, can need according to different air pressure to regulate the air pressure in air-flow cylinder, thus regulating the rotary speed of drill bit.
Accompanying drawing explanation
Fig. 1 is the structural representation of the air-flow cylinder that the embodiment of the present invention provides.
Detailed description of the invention
The beneficial effect of the technical problem solved to make the present invention, the technical scheme of employing and generation is clearly understood, is described in further detail the present invention below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only for explaining the present invention, being not intended to limit the present invention.
It should be noted that, when element is called as " being fixed on " or " being arranged at " another element, it can directly on another element or may there is centering elements simultaneously." being socketed on " another element when an element is called as, it can be directly connected to another element or may there is centering elements simultaneously.
Particularly, as shown in Figure 1, the invention provides a kind of air-flow cylinder of air stream drives formula boring bar tool, comprise internal layer air-flow cylinder 1 and be socketed on its outside and highly equal outer gas flow cylinder 2, outer gas flow cylinder 2 is provided with the first air admission hole 21 and the second air admission hole 22, the sidewall of internal layer air-flow cylinder 1 is provided with multiple air-vent 11, is provided with helical blade 3 in internal layer air-flow cylinder 1.By arranging the socket join structure of internal layer air-flow cylinder 1 and outer gas flow cylinder 2, store enough air pressure in outer gas flow cylinder 2 to rotate for driving the helical blade 3 in internal layer air-flow cylinder 1, and be provided with at the sidewall of internal layer air-flow cylinder 1 contact area that air-vent 11 increases air-flow and helical blade 3, provide sufficient power for it rotates.
Particularly, the first air admission hole 21 and the second air admission hole 22 place are separately installed with air-flow filter bowl 4 with matching.Can prevent from entering in the air-flow in air-flow cylinder be mixed into impurity by arranging air-flow filter screen 4, wearing and tearing are caused to the parts in internal layer air-flow cylinder 1.
Particularly, the first air admission hole 21 and the second air admission hole 22 are respectively equipped with barometric damper 5.By arranging barometric damper 5, can need according to different air pressure to regulate the air pressure in air-flow cylinder, thus regulating the rotary speed of drill bit.
These are only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement or improvement etc., all should be included within protection scope of the present invention.
