Abstract
The utility model provides a milling machine arbor used for a horizontal knee-and-column milling machine. The milling machine arbor has a shape of multidiameter in appearance. One end of the milling machine arbor is a main spindle mounting end, the other end of the milling machine arbor is a cutter head mounting end, a first threaded hole is arranged on the end surface of the main spindle mounting end, and the circumference of the main spindle mounting end is provided with taper matched with main spindle of the milling machine, and a first key slot connected with the main spindle of the milling machine; a second threaded hole is arranged on the end surface of the cutter head mounting end, and the circumference of the section of the cutter head mounting end is provided with a second key slot connected with a cutter head. The utility model has the following advantages: firstly, the operation is convenient, and the method for operating the milling machine is not changed; secondly, the surface milling processing performance of the milling machine is effectively adopted; thirdly, the applicability is great; and fourth, the surface milling cutter arbor does not need to be bought, which saves cost.
Description
Technical field
The utility model relates to a kind of lathe knife bar, especially a kind of horizontal kneeand-column type milling machine that is used for, the knife bar of connection tool rest spindle hole and cutterhead.
Background technology
The X61 horizontal kneeand-column type milling machine is to make nineteen sixty-eight to dispatch from the factory.Owing to the restriction that is subjected to produce at that time, the knife bar configuration is incomplete, particularly processes the knife bar of facing cut, can't accept the large batch of order that needs processing to mill face.Though the X6132A universal knee-and-column milling machine is equipped with the facing cut knife bar, because of the spindle taper hole degree difference of these two milling machines, the facing cut knife bar of X6132A universal knee-and-column milling machine can't be directly used on the X61 horizontal kneeand-column type milling machine.
The utility model content
The technical problems to be solved in the utility model provides the milling machine knife bar that a kind of X61 of can be used for horizontal kneeand-column type milling machine carries out facing cut, to overcome the defective that this milling machine can't mill face in the prior art.
The utility model is by the following technical solutions:
A kind of milling machine knife bar, profile is the multidiameter shape, this milling machine knife bar one end is the main shaft installation end, the other end is the cutterhead installation end, described main shaft installation end end face is provided with first screwed hole, and the periphery of main shaft installation end has the tapering that matches with milling machine spindle and is provided with first keyway that is connected with milling machine spindle; Described cutterhead installation end end face is provided with second screwed hole, and the periphery of cutterhead installation end is provided with second keyway that is connected with cutterhead.
Preferably, described first keyway and second keyway respectively have two, and are symmetrically distributed on the periphery of milling machine knife bar.
The utlity model has following beneficial effect: (1) is easy to operate, does not change the method for operating of its milling machine; (2) effectively utilize the facing cut processing characteristics of this milling machine; (3) applicability is strong; (4) do not need to buy in addition the facing cut knife bar, save cost.
Description of drawings
Fig. 1 is the vertical view of milling machine knife bar.
Fig. 2 is the vertical view of the milling machine knife bar among Fig. 1 after axis turns over 90 degree.
The specific embodiment
As Fig. 1, shown in 2, profile of the present utility model is the multidiameter shape, one end is a main shaft installation end 1, the other end is a cutterhead installation end 3, described main shaft installation end 1 end face is provided with first screwed hole 6, and the periphery of main shaft installation end 1 has the tapering that matches with milling machine spindle and is provided with first keyway 2 that is connected with milling machine spindle; Described cutterhead installation end 3 end faces are provided with second screwed hole 4, and the periphery of cutterhead installation end 3 is provided with second keyway 5 that is connected with cutterhead.Described first keyway 2 and second keyway 5 respectively have two, and are symmetrically distributed on the periphery of milling machine knife bar.
During assembling, the main shaft installation end 1 of milling machine knife bar is contained in the spindle hole of lathe fixingly, knife bar is connected the taper fit of knife bar tapering and main shaft with the main shaft pull bar.The 2 constraint radial displacements of first keyway, screwed hole constraint axial displacement is similarly loaded onto cutterhead at other end cutterhead installation end 3 then, after cutterhead loaded onto, Upper gasket makes it closely to link with screwed hole with bolting, reaches the effect of axial restraint cutterhead, by the 5 constraint axial displacements of second keyway.
Claims (2)
1. milling machine knife bar, profile is the multidiameter shape, this milling machine knife bar one end is the main shaft installation end, the other end is the cutterhead installation end, it is characterized in that: described main shaft installation end end face is provided with first screwed hole, and the periphery of main shaft installation end has the tapering that matches with milling machine spindle and is provided with first keyway that is connected with milling machine spindle; Described cutterhead installation end end face is provided with second screwed hole, and the periphery of cutterhead installation end is provided with second keyway that is connected with cutterhead.
2. milling machine knife bar according to claim 1 is characterized in that: described first keyway and second keyway respectively have two, and are symmetrically distributed on the periphery of milling machine knife bar.
