Abstract
The invention discloses a drilling and boring integrated deep hole machining device. The drilling and boring integrated deep hole machining device is characterized in that the drilling and boring integrated deep hole machining device comprises a drill bit, the drill bit is connected with a cutter bar, a boring cutter is arranged in the radial position of the drill bit, and a circulating cooling mechanism is arranged on the cutter bar. The drill bit at the front portion of the deep hole machining device conducts drilling, the boring cutter behind the drill bit conducts boring, therefore, combined type drilling and boring integrated machining is conducted on a horizontal lathe, rough machining and finish machining are simultaneously conducted, and machining is completed at a time without clamping and correcting. When the drill bit conducts deep hole drilling, the boring cutter behind the drill bit conducts boring at the same time, a clearance is formed between the drill bit and a workpiece, cutting liquid is filled into the clearance and used for conducting cooling, and the service life of the drill bit and the service life of the boring cutter are prolonged. Meanwhile, when the boring cutter conducts cutting, a center hole is naturally formed in the workpiece through the drill bit in front of the boring cutter and the drill bit is positioned, therefore, vibration caused by an overlong cantilever of the boring cutter is prevented, and the machining straightness and the size accuracy can be ensured.
Description
Technical field
The present invention relates to bore boring deep hole machining field, specifically, relate 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 the 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 can't be used cutting fluid cooling, and drill bit easily overheated, quick abrasion, chip removal is not smooth, needs frequently to exit drill bit in boring procedure and carries out chip removal, affects production efficiency, and the drill bit loss is also very large.Deep hole drills process and is easy to fracture, and often is difficult to after fractureing take out and makes the whole workpiece waste product, and the degree of depth is larger, and the probability of broken drill is larger; The boring deep hole need to minute multistep carry out thick fine finishining, and efficiency is extremely low, and when processing the machine tool chief axis cantilever long, the right boring operation is easy to cause machining accuracy low because cutter trembles.
Summary of the invention
The invention provides the integrated deep hole drilling apparatus of a kind of brill boring, solved drill bit frangibility in the deep hole machining process, production efficiency is low, the technical barrier that machining accuracy is not high.
The present invention adopts following technical scheme to realize goal of the invention:
The integrated deep hole drilling apparatus of a kind of brill boring is characterized in that: comprise drill bit, described drill bit connects knife bar, in the radial position of drill bit, boring cutter is installed, and described boring cutter, through the shaft centre line of described drill bit, is provided with cooling body on described knife bar.
As the further restriction to the technical program, described cooling body comprises the knife bar inner chamber that cooling fluid enters hole and communicates with it, and 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 invention and good effect are: the drill bit of front portion of the present invention carries out drilling, and the boring cutter of back carries out boring, realizes synchronously carrying out combined type and bore the integrated processing of boring on horizontal lathe, thick fine finishining is carried out simultaneously, and a step processing puts in place without the secondary clamping centering; During the bit drills deep hole, the boring cutter at rear completes boring work simultaneously, form gap between drill bit and workpiece, the injection cutting fluid is cooling, extended service life of drill bit, boring cutter, simultaneously, during the 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.

The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the present invention 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.
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.
The present invention 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 limitation of the present invention; the present invention also is not limited in above-mentioned giving an example; the variation that those skilled in the art make in essential scope of the present invention, remodeling, interpolation or replacement, also should belong to protection scope of the present invention.
