Abstract
The utility model discloses a drilling and boring integrated deep hole machining device. The drilling and boring integrated deep hole machining device is characterized in that a drill bit is included, the drill bit is connected with a tool rod, a boring tool is arranged at the radial position of the drill bit, and a circulating cooling mechanism is arranged on the tool rod. The drill bit on the front portion of the device is used for drilling, the boring tool on the rear side of the device is used for boring, combined type drilling and boring integrated machining is synchronously carried out on a horizontal lathe, rough machining and fine machining are carried out simultaneously, machining is achieved at one step, and secondary clamping and centering is not needed. The boring tool on the rear side simultaneously achieves boring work when the drill bit drills a deep hole, a clearance is formed between the drill bit and a workpiece, cutting liquid is injected into the clearance for cooling, the service life of the drill bit and the boring tool is prolonged, meanwhile, vibration caused by a too long suspension arm of the boring tool is avoided due to the fact that central hole locating is naturally formed in the workpiece through the drill bit in front of the boring tool when the boring tool carries out cutting, and machining straightness and size precision can be guaranteed.
Description
Technical field
The utility model relates to brill boring deep hole machining field, specifically, relates to the integrated deep hole drilling apparatus of a kind of brill boring.
Background technology
In the process of the products such as all kinds of roller-ways of processing conticaster, this type of inner hole of workpiece belongs to deep hole machining, and draw ratio surpasses 1:10.The traditional handicraft of mechanical processing industry is first on solid round steel, to hole, the original way of then carrying out secondary Boring on boring machine again expands the large endoporus of boring, for example the solid round steel centre bore hole of φ 280 to φ 120, operation is first to use common bit drills aperture, then substep bores the φ 120 that precision is higher.The shortcoming of conventional machining process is that drilling operating cannot be used cutting fluid cooling, and drill bit easily overheated, quick abrasion, chip removal is not smooth, needs frequently to exit drill bit and carry out chip removal in boring procedure, affects production efficiency, and drill bit loss is also very large.Deep hole drills process and is easy to fracture, and is often difficult to take out and makes whole workpiece waste product after fractureing, and the degree of depth is larger, and the probability of broken drill is larger; Boring deep hole need to minute multistep carry out thick fine finishining, and efficiency is extremely low, and when processing machine tool chief axis cantilever long, right boring operation is easy to cause machining accuracy low because cutter trembles.
Utility model content
The utility model provides a kind of brill boring integrated deep hole drilling apparatus, has solved drill bit frangibility in deep hole machining process, and production efficiency is low, the technical barrier that machining accuracy is not high.
The utility model adopts following technical scheme to realize utility model object:
The integrated deep hole drilling apparatus of a kind of brill boring, it is characterized in that: comprise drill bit, described drill bit connects knife bar, radial position at drill bit is provided with boring cutter, described boring cutter, through the shaft centre line of described drill bit, is provided with cooling body on described knife bar, and described cooling body comprises the knife bar inner chamber that cooling fluid enters hole and communicates with it, described cooling fluid enters the axis direction that hole is arranged at described knife bar, vertical with described knife bar inner chamber.
As the further restriction to the technical program, described drill bit and knife bar are welded as a whole.
As the further restriction to the technical program, described boring cutter is arranged on described drill bit by installing hole.
Compared with prior art, advantage of the present utility model and good effect are: the drill bit of the utility model front portion carries out drilling, boring cutter below carries out boring, realization is synchronously carried out combined type and is bored the integrated processing of boring on horizontal lathe, thick fine finishining is carried out simultaneously, and a step processing puts in place without secondary clamping centering; During bit drills deep hole, the boring cutter at rear completes boring work simultaneously, between drill bit and workpiece, form gap, injection cutting fluid is cooling, extended service life of drill bit, boring cutter, simultaneously, during boring cutter cutting, drill bit self-assembling formation centre bore location in workpiece in the place ahead has avoided the long generation of boring cutter cantilever to tremble, and can guarantee processing linear degree and dimensional accuracy.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model preferred embodiment.
Fig. 2 is the A-A cutaway view of Fig. 1.
1. drill bit 2. boring cutter 3. knife bar 4. chuck 5. workpiece 6. centre frame 7. cooling fluids enter hole, and 8, knife bar inner chamber.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is further described in detail.
Referring to Fig. 1 and Fig. 2, described drill bit 1 connects knife bar 3, in the radial position of drill bit 1, boring cutter 2 is installed, and described boring cutter 2, through the shaft centre line of described drill bit 1, is provided with cooling body on described knife bar 3.
Described cooling body comprises the knife bar inner chamber 8 that cooling fluid enters hole 7 and communicates with it, and described cooling fluid enters the axis direction that hole 7 is arranged at described knife bar 3, vertical with described knife bar inner chamber 8.
Described drill bit 1 and knife bar 3 are welded as a whole.
Described boring cutter 2 is arranged on described drill bit 1 by installing hole.
Drill bit 1 of the present utility model is for getting out roughing deep hole part; Boring cutter 2 is immediately following drilling process fine finishining deep hole part; Knife bar 3 supports drill bit and boring cutter its internal cavity as the passage of circulating cooling liquid; Chuck 4 clamping work pieces; Workpiece 5 needs the workpiece of deep hole processing; Centre frame 6 plays the effect of supporting workpiece; Cooling body 7 is for the cooling cutter of liquid circulation.
The roller that the internal diameter of take is φ 100 is example, uses φ 90 drill bits 1, is welded and fixed to knife bar 3, and at drill bit 1 rear portion processing mounting holes, is used for installing boring cutter 2, and boring cutter both sides blade forms φ 100 fine finishining scopes.
Drill bit 1, boring cutter 2 and knife bar 3 have been assembled to rear integral installation to horizontal drilling machine, used centre frame fixedly workpiece to be processed 5 and knife bar 3 shafts, started drilling machine level and cut, cooling fluid is injected by the 8 space circulations of knife bar inner chamber, absorb heat in metal cutting, cooling cutter, extends cutter life; Overheated and damage cutter while preventing the 2 blades cutting of drill bit 1 and boring cutter.This device belongs to novel edge structure, improves iron filings shape, is beneficial to chip removal, avoids iron to cut after excessive resulting in blockage the accidents such as broken drill.During boring cutter 2 cutting, the place ahead drill bit 1 self-assembling formation centre bore positioning action in workpiece, not only can prevent from processing sideslip, has more avoided the long formation knife mark that trembles of boring cutter cantilever to affect machining accuracy.
The utility model can pass through or adopt existing techniques in realizing without the technical characterictic of describing; do not repeat them here; certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned giving an example; the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
