Abstract
The utility model discloses a fixing device for a boring tool. The fixing device for the boring tool comprises a boring tool bar which is connected and fixed with a boring machine spindle, and a boring tool which is fixed on the boring tool bar, wherein one end connected with the boring machine spindle, of the boring tool bar, is a conical body, a boring tool installation square hole is formed at the other end of the boring tool bar, and a boring tool locking hole is formed on the wall of the square hole; and the boring tool is fixed in the square hole by virtue of a bolt via the locking hole. The boring tool bar of the fixing device disclosed by the utility model adopts a structure which is connected and matched with the boring machine spindle, and connected, fixed and matched with the boring tool respectively, and the conical body which is connected and matched with the boring machine spindle is a unified structure, thus being adaptive to the need of being connected and fixed with a boring machine; the boring tool installation square hole at the other end of the boring tool bar also adopts a unified structure, thus being adaptive to conveniently replace the boring tool at any time during hole-boring machining; the boring tool can be conveniently and efficiently fixed via the fixing structure of the locking hole and the bolt; the integrated fixing device is few in connection links and high in connection strength; and via the direct connection method, the vibration of the tool is weakened, and the rigidity and the machining accuracy of the tool are improved.
Description
Technical field
The utility model belongs to field of machining and machinebuilding technology, particularly a kind of novel borer fixture that is used for bore hole.
Background technology
All have one to be connected fixture between the borer of using on the existing boring machine and the boring spindle; Connect fixture more multi-link retainer ring joint is arranged usually; This device increases the junction to cause cutter to produce vibration and has strengthened difficulty of processing; Finally cause the machining accuracy of intensely processed products to descend, crudy descends.The problems referred to above usually through increase each fixedly the constant intensity of link solve with methods such as increasing the fixture rigidity, but be unfavorable for reducing production costs and the realization production that routinizes.
Summary of the invention
The utility model discloses a kind of borer fixture according to the deficiency of prior art.The problem that the utility model will solve provides a kind of simple in structure, and is easy for installation, can improve the direct-coupled type borer fixture of machining accuracy.
The utility model is realized through following technical scheme:
The borer fixture; Comprise and be connected fixing boring bar with boring spindle and be fixed on the boring cutter on the boring bar; It is characterized in that: said boring bar is connected an end with boring spindle be bullet, and the boring bar other end has boring cutter that square hole is installed, and the square hole wall has the boring cutter locking hole.
Said boring cutter is used bolt through locking hole in square hole.
When the said fixing device uses, pack into boring cutter in the installation square hole of boring bar earlier and lock with the locking hole place of bolt at boring bar.Again the bullet of its boring bar is connected with boring spindle and gets final product.
The utility model helpfulness is: the utility model boring bar adopts and is connected the structure of mating and being connected fixing coupling with boring cutter respectively with boring spindle, and the bullet that is connected coupling with boring spindle is unified structure, and adaptation is connected fixing needs with boring machine; The boring cutter of the boring bar other end is installed square hole and is also adopted unified structure, adapts in bore hole processing to be convenient for changing boring cutter at any time; Locking hole and bolt structure can be easily and effectively fixing boring cutter; Overall fixed device connecting link is few, and bonding strength is high; The method that directly links to each other has weakened vibration cutting, has improved cutter rigidity and machining accuracy; And structure is simple more, reliable, more convenient to operate, quick.
Description of drawings
Fig. 1 is the utility model fixture boring bar structural representation;
Fig. 2 is the utility model boring cutter structural representation.
Among the figure, the 1st, boring bar, 1a are the awl gonosomes, and 1b installs square hole, and 1c is a locking hole, the 2nd, boring cutter.
The specific embodiment
Through the specific embodiment and accompanying drawing the utility model is further specified below.Embodiment is used to explain the utility model, limits the utility model never in any form.
In conjunction with Fig. 1, Fig. 2.
The borer fixture; Comprise and be connected fixing boring bar 1 with boring spindle and be fixed on the boring cutter 2 on the boring bar 1; Boring bar 1 is connected an end with boring spindle be bullet 1a, and boring bar 1 other end has boring cutter 2 that square hole 1b is installed, and square hole 1b wall is installed has boring cutter 2 locking hole 1c.
As shown in the figure; Boring bar 1 one ends are bullet 1a; The conical surface of bullet 1a and tapering and boring spindle syndeton coupling; Unified conveniently when difference processing needs, be connected with boring spindle fixing that be provided with of bullet 1a with boring bar 1 has the rectangle head further to increase constant intensity in bullet 1a end; The length of boring bar 1 is according to processing needs decisions, but the diameter that normal length can increase the middle part knife bar when longer reduces deformation effect such as vibration machining accuracy to increase stiffness; Boring bar 1 other end has the installation square hole 1b that passes the knife bar center; Square hole 1b size and boring cutter 2 handle of a knife stiff ends size coupling are installed; Square hole 1b is installed near boring bar 1 end; Square hole 1b wall is installed has the locking hole 1c that passes boring bar 1 end, and locking hole 1c is provided with more than 2 with the boring cutter 2 among the fixed installation square hole 1b as required.
When fixture is used, earlier with pack into the installation square hole mouth 1b of boring bar 1 and lock of boring cutter 2 with the locking hole 1c place of bolt at boring bar 1.Again the bullet 1a of boring bar 1 is connected with boring spindle and gets final product.
Claims (2)
1. borer fixture; Comprise and be connected fixing boring bar (1) with boring spindle and be fixed on the boring cutter (2) on the boring bar (1); It is characterized in that: said boring bar (1) is connected an end with boring spindle be bullet (1a); Boring bar (1) other end has boring cutter (2) that square hole (1b) is installed, and square hole (1b) wall has boring cutter (2) locking hole (1c).
2. borer fixture according to claim 1 is characterized in that: said boring cutter (2) is used bolt through locking hole (1c) in square hole (1b) is installed.
