Abstract
The utility model belongs to the technical field of drilling of deep hole drilling and boring machines, and particularly relates to a device used for improving the drill rod stability in deep hole drilling. The device comprises an outer ring, a taper sleeve base, a taper sleeve, a locknut and a thrust ball bearing. The taper sleeve base is arranged on a drill rod base in a sleeved mode and rotates with the drill rod base, the taper sleeve is arranged on a drill rod in a sleeved mode, and the taper sleeve is arranged on the taper sleeve base in a sleeved mode. The thrust ball bearing and the locknut are arranged on the drill rod in a sleeved mode in sequence, and are fixed through the outer ring. The outer ring is arranged on a support on the circumference of the drill rod in an erected mode, and gaps are reserved between the thrust ball bearing and the drill rod and between the locknut and the drill rod. The device is installed on an original device; when a taper tile sleeve is in a loosening state, an operator can adjust the taper tile sleeve at any time, the taper sleeve base in the structure is in contact with the taper face of the tile sleeve, an adjusting nut is in contact with the end face of the taper tile sleeve through the thrust ball bearing; when adjustment is needed, the adjusting nut is screwed to push the taper tile sleeve to clamp the drill rod tightly, and the function of stabilizing the drill rod is achieved.
Description
Technical field
The utility model belongs to the technical field of deep hole drilling and boring machine boring, is specifically related to a kind of device that increases drilling rod stability for gun drilling.
Background technology
Gun drilling occupies very important status in machining, in gun drilling, there is boring cutter sometimes, bore cutter is forged a knife, the situations such as spiral lamination appears in the product processing, the faulting of slab ends of forging a knife, " large tripe ", there is these situations, slight impacts following process, and serious will cause product rejection.The stability of cutting in gun drilling process is the key factor that guarantees crudy.
In deep hole drilling, the stability of drilling rod is that the tapered watt of cover by awarding oily device and drill rod rack inside held tightly to realize, and it is that a set of mechanism by awarding oily device and drill rod rack inside adjusts that taper watt cover is held tightly.And the TS2180 type deep hole drilling and boring machine that we use now, awarding this on oily device and drill rod rack, to overlap institutional adjustment very inconvenient, must be just can carry out under stopped status in the time of need to adjusting.Its taper watt cover rotates with boring bar, when lathe, when drilling is processed, cannot adjust at random, causes the less stable of drilling rod in boring procedure, affects inner hole of workpiece crudy.
Summary of the invention
The purpose of this utility model is exactly a kind of device that can increase drilling rod stability in gun drilling process of design.
The purpose of this utility model is achieved in that
A kind of device that increases drilling rod stability, comprise outer ring, tapered sleeve seat, tapered sleeve, locking nut and thrust ball bearing, wherein said tapered sleeve cover for seat is contained on safety chuck, and rotate together with safety chuck, described tapered sleeve is sleeved on drilling rod, and be set with tapered sleeve, described tapered sleeve and tapered sleeve cover for seat dress, described drilling rod is also set with thrust ball bearing and locking nut successively, described thrust ball bearing and locking nut are fixed by outer ring, described outer circle rack is located on the support of drilling rod circumference, between described thrust ball bearing and locking nut and drilling rod, all leave space.
Described thrust ball bearing and locking nut are fixedly set in outer ring.
Described tapered sleeve has the part of four deciles to form.
The mode that described outer ring is bolted is connected with the support of drilling rod circumference.
Described outer ring also forms suit with tapered sleeve seat.
The utlity model has following advantage:
This device is installed on original equipment, and when loosening state appears in a taper watt cover, operative employee can adjust at any time.In structure, tapered sleeve seat contacts with a watt cover conical surface, and adjusting nut, by thrust ball bearing and taper watt cover end contact, in the time of need to adjusting, advances a taper watt cover to hug drilling rod by rotation adjusting nut, plays the effect of stablizing drilling rod.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of device that increases drilling rod stability, it is characterized in that: comprise outer ring 1, tapered sleeve seat 2, tapered sleeve 3, locking nut 4 and thrust ball bearing 5, wherein said tapered sleeve seat 2 is sleeved on safety chuck, and rotate together with safety chuck, described tapered sleeve 3 is sleeved on drilling rod, and be set with tapered sleeve 3, described tapered sleeve 3 is set with tapered sleeve seat 2, described drilling rod is also set with thrust ball bearing 5 and locking nut 4 successively, described thrust ball bearing 5 and locking nut 4 are fixing by outer ring 1, described outer ring 1 is erected on the support of drilling rod circumference, between described thrust ball bearing 5 and locking nut 4 and drilling rod, all leave space.
Described thrust ball bearing 5 and locking nut 4 are fixedly set in outer ring 1.
Described tapered sleeve 3 has the part of four deciles to form.
The mode that described outer ring 1 is bolted is connected with the support of drilling rod circumference.
Described outer ring 1 also forms suit with tapered sleeve seat 2.
Adjusting nut 4 is to tapered sleeve 3 direction rotations, give 5 one thrusts of thrust ball bearing, thrust ball bearing 5 passes to tapered sleeve 3 by this thrust, tapered sleeve 3 can produce axial displacement under the effect of this thrust, utilize the cone match of tapered sleeve 3 pintongs and the conical surface and tapered sleeve seat 2 to tighten principle, the endoporus in tapered sleeve 3 can constantly dwindle drilling rod is held tightly.Tapered sleeve 3 rotates with drilling rod.In the middle of tapered sleeve 3 and nut 4, have the effect of thrust ball bearing 5, adjusting nut 4 can not rotate with drilling rod, and stable under rotation status of drilling rod just can regulate by rotating adjusting nut 4 like this, assurance drilling rod in Drilling operation the moment in stable state.
Claims (5)
1. one kind increases the device of drilling rod stability, it is characterized in that: comprise outer ring (1), tapered sleeve seat (2), tapered sleeve (3), locking nut (4) and thrust ball bearing (5), wherein said tapered sleeve seat (2) is sleeved on safety chuck, and rotate together with safety chuck, described tapered sleeve (3) is sleeved on drilling rod, and be set with tapered sleeve (3), described tapered sleeve (3) and tapered sleeve seat (2) suit, described drilling rod is also set with thrust ball bearing (5) and locking nut (4) successively, described thrust ball bearing (5) and locking nut (4) are fixing by outer ring (1), described outer ring (1) is erected on the support of drilling rod circumference, between described thrust ball bearing (5) and locking nut (4) and drilling rod, all leave space.
