Abstract
The utility model discloses a deep hole drilling device for a lathe, which belongs to a pipe fitting drilling device and solves the problems of high price and poor practicability of a deep hole drilling device in the prior art. The deep hole drilling device comprises a drill bit, a drill rod, a copper pipe, a semiring and a guide sleeve; the drill bit is mounted at one end of the drill rod through threaded connection; a strip-shaped groove is formed on the outer surface of the drill rod along the axial direction thereof; the hollow copper pipe is mounted in the strip-shaped groove which is filled with coolant liquid with certain pressure; the section of the strip-shaped groove takes the shape of the letter U; the deep hole drilling device is further provided with a guide sleeve which is arranged at the middle part of the drill rod; and the two ends of the guide sleeve are fixed on the drill rod through the semiring. The utility model has the advantages of simple structure, convenient installation, reliable guidance, good cooling effect and low manufacturing cost, and effectively reduce the use and maintenance cost, and has great utility value.
Description
Technical field
The utility model relates to a kind of drilling equipment of elongated deep hole.
Background technology
In oil-well drilling equipment, great majority all are elongated pipe parts, wherein much all be the deep hole part of draw ratio greater than 5 (L/D＞5), the draw ratio of individual part even reached more than 20 (L/D＞20), this brings great difficulty for production and processing of part.Its main difficult point is: 1. drilling rod is elongated, and poor rigidity makes the precision in hole be difficult to be guaranteed; 2. the hole depth smear metal is many, and channel of chip removal is long and narrow, and smear metal is difficult for discharging; 3. the hole is too dark, and cooling fluid is difficult to enter, the heat radiation difficulty, and cutter head is easy to wear.
At present, the equipment of processing above-mentioned deep hole mainly is deep hole drilling and boring machine (as T2120, maximum boring diameter 200mm, maximum boring depth 5m), and deep hole drilling and boring machine is the price height not only, take up an area of greatly, and also the cutter head structure complexity, operation and maintenance cost height.
The utility model content
The purpose of this utility model is to provide a kind of lathe depth drill device, under the deep hole drilling prerequisite that realizes L/D＞10, reduces the loss of depth drill device, prolongs its service life.
To achieve these goals, the technical solution adopted in the utility model is as follows:
Lathe depth drill device comprises drilling rod, and the drill bit that is fixed in drilling rod one end.
Described drill bit and drilling rod are by being threaded.
The outer surface of described drilling rod axially offers strip groove along it, is provided with hollow copper tubing in strip groove, and cooling fluid is housed in the copper pipe.
The cross section of described strip groove is " U " shape.
Described depth drill device also is provided with fairlead, and fairlead is arranged at the drilling rod middle part, and the two ends of fairlead all are fixed on the drilling rod by semi-ring.
Because drill bit and drill bit adopt and are threaded in the utility model, therefore can adopt the drilling rod of changing different length to adapt to the pipe fitting of all lengths, simultaneously, can also change the drill bit and the fairlead of various outer diameter, realize the deep hole machining in different apertures, adaptability is very strong.
The utility model is simple in structure, and is easy for installation, and guiding is reliable, good cooling results, and production cost is low, and can effectively reduce and use and maintenance cost, has great practical value.
The petroleum pipe fitting of the deep hole machining, particularly overlength of farm labourer's part boring processing during the utility model is mainly used in.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, lathe depth drill device comprises drill bit 2, drilling rod 1, copper pipe 3, semi-ring 5, fairlead 4, and drill bit 2 is by being threadedly connected to drilling rod 1 one ends; Outer surface at described drilling rod 1 is axially offered a strip groove along it, and copper pipe 3 is installed in the strip groove, and this copper pipe 3 is a hollow copper tubing, and the cooling fluid of certain pressure is equipped with in inside; The cross section of described strip groove is " U " shape; Described depth drill device also is provided with fairlead 4, and fairlead 4 is arranged at drilling rod 1 middle part, and its two ends all are fixed on the drilling rod 1 by semi-ring 5.
During use, earlier drill bit 2 usefulness are threadedly connected to the top of drilling rod 1, drill bit 2 is mainly born the effect of cutting; And elongated drilling rod 1 is the matrix of whole depth drill device, from the root to the top, offer the strip groove of a cross section on its outer surface for " U " shape, hollow copper tubing 3 of soldering in the strip groove, insert the cooling fluid of certain pressure in the copper pipe 3, in the depth drill device course of work, cooling fluid will constantly be dripped in the deep hole of into offering, and play a part cooling deep borehole boring device and chip breaking, thereby the raising stock-removing efficiency, the service life of extension fixture.At the middle part of drilling rod 1, be provided with a fairlead 4, the two ends of fairlead 4 are respectively equipped with two semi-rings 5, and fairlead 4 is axially fixed on drilling rod 1 outer surface.In the deep hole processing process, fairlead plays a part guide-localization, thereby has reduced the flexural deformation of drilling rod, has improved the machining accuracy of boring effectively.
In the production, can process the deep hole in different apertures by changing the drill bit and the fairlead of various outer diameter.The utility model is easy and simple to handle, practicality, and cost is low, has very high practical value.
