Description
[technical field]
The utility model relates to Machining Technology field, particularly the technical field of drilling machine Hardware fitting.
[background technology]
In Mechanical Product's Machining, must use drilling machine, drill bit is the vitals of drilling machine.Drill bit goes out through hole or blind hole in order to drilling on solid material, and can to the cutter of existing hole reaming.Conventional drill bit mainly contains fluted drill, chit drill, centre drill, depth drill and cylindrical drill; Conventional drill comprises drillstock, hollow boring bit, fluted drill and trip bolt.
At present, the drill bit generally used mostly is single type, and during drilling larger aperture workpiece, common way first drills through, and then use instead larger drill bit to remove second reaming with smaller drill bit; In existing technology, workpiece after piercing, needs to carry out chamfering to aperture, and common way more carries out chamfering again after bit change, and the method needs more bit change; The processing of the various shoulder holes of high number on large-scale workpiece in addition, must repeatedly more bit change, reduces productivity ratio to a certain extent, and frequent more bit change, and easily damage fixture, labour intensity strengthens simultaneously, is not suitable with current enterprise growth requirement.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, a kind of drilling machine Hardware fitting is proposed, can realize once completing boring, reaming, chamfering, when processing larger hole, do not need successively to use two kinds of drill bits again, while completing boring and reaming, carry out chamfering to hole, manufacturing procedure is greatly simplified, working (machining) efficiency improves.
For achieving the above object, the utility model proposes a kind of drilling machine Hardware fitting, comprise drillstock, chamfering section and segment of cutting, described drillstock, chamfering section are connected with segment of cutting integral type, described drillstock is connected with chamfering section, described chamfering section is cylindric, and chamfering section lower end is provided with chamfering blades, and chamfering section outer wall is provided with flute; Described chamfering section is connected with segment of cutting, and described segment of cutting comprises large drill bit and little drill bit, and large drill bit is connected with bradawl head integral type, and described segment of cutting is provided with cutting edge, and little drill bit lower end is provided with drill bit tip.
As preferably, the described order of connection is drillstock, chamfering section and segment of cutting, and be topmost drillstock, centre is chamfering section, is segment of cutting bottom.
As preferably, the order of connection of described segment of cutting is large drill bit, little drill bit, and upper end is large drill bit, and lower end is little drill bit.
As preferably, the quantity of described chamfering blades is at least 2.
As preferably, described cutting edge is arranged along the outer wall of large drill bit and little drill bit, and cutting edge in the shape of a spiral.
The beneficial effects of the utility model: the utility model is by using the large drill bit of one connection and little drill bit, and on bit body, chamfering blades is set, realization boring, reaming, chamfering once complete, when processing larger hole, do not need to re-use two kinds of drill bits and successively change drilling, directly can use, while completing boring and reaming, chamfering be carried out to hole, manufacturing procedure is greatly simplified, and working (machining) efficiency improves.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is the structural representation of a kind of drilling machine Hardware fitting of the utility model.
In figure: 1-drillstock, 2-chamfering section, 3-flute, 4-chamfering blades, 5-segment of cutting, the large drill bit of 6-, the little drill bit of 7-, 8-drill bit tip, 9-cutting edge.
[detailed description of the invention]
Consult Fig. 1, the utility model, comprise drillstock 1, chamfering section 2 and segment of cutting 5, described drillstock 1, chamfering section 2 are connected with segment of cutting 5 integral type, and described drillstock 1 is connected with chamfering section 2, and described chamfering section 2 is in cylindric, chamfering section 2 lower end is provided with chamfering blades 4, and chamfering section 2 outer wall is provided with flute 3; Described chamfering section 2 is connected with segment of cutting 5, and described segment of cutting 5 comprises large drill bit 6 and little drill bit 7, and large drill bit 6 is connected with little drill bit 7 integral type, and described segment of cutting 5 is provided with cutting edge 9, and little drill bit 7 lower end is provided with drill bit tip 8.The described order of connection is drillstock 1, chamfering section 2 and segment of cutting 5, and be topmost drillstock 1, centre is chamfering section 2, is segment of cutting 5 bottom.The order of connection of described segment of cutting 5 is large drill bit 6, little drill bit 7, and upper end is large drill bit 6, and lower end is little drill bit 7.The quantity of described chamfering blades 4 is at least 2.Described cutting edge 9 is arranged along the outer wall of large drill bit 6 and little drill bit 7, and cutting edge 9 in the shape of a spiral.
Utility model works process:
In the course of the work, the little drill bit 7 of leading portion completes drilling task to a kind of drilling machine Hardware fitting of the utility model, and the large drill bit 6 of back segment completes reaming task, makes drill tasks convenience and high-efficiency; After having holed, chamfering blades 4 can in hole along carrying out chamfering, when holing, the flute 3 on chamfering section 2 outer wall workpiece drilling can be produced bits bar, bits powder drain smoothly.
