Brief description of the drawings
Fig. 1 shows the utility model structural representation.
Fig. 2 shows that the utility model processes the implementation schematic diagram of inner circle semicircle orifice.
Specific embodiment
As depicted in figs. 1 and 2, a kind of vertical milling cutter for roughing inner circle semicircle orifice, including locating dowel 1, transverse arm 2,
Cutter holder 3 and milling cutter 4.The locating dowel 1 is used to position the home position of semicircle orifice to be processed 9, to ensure that the transverse arm 2 rotates
The accuracy of the semicircle camber line of formation.The cutter holder 3 clamps semicircle orifice 9 described in the Milling Process of the milling cutter 4.
The transverse arm 2 is sheathed on the outside of the locating dowel 1.The inner side of the transverse arm 2 is provided with pitch adjusting structure 5, and the cutter holder 3 blocks
In the pitch adjusting structure 5.The spacing of the cutter holder 3 and the locating dowel 1 is controlled by adjusting the pitch adjusting structure 5, from
And determine the milling cutter 4 and rotate the semicircle arc radius of milling.
The pitch adjusting structure 5 uses rack pinion roll-setting gear.It is easy to accuracy controlling.And rack pinion roll adjustment
Device can carry out automatic regulation, be conducive to improving machining accuracy and processing efficiency.
Stopper slot 21 is provided with the transverse arm 2.Stop screw 31, the stop screw are provided with the lateral wall of the cutter holder 3
31 slide along the stopper slot 21, fix.The stop screw 31 is fixed with the cooperation of the stopper slot 21, so as to further solid
The fixed cutter holder 3 and the spacing of the locating dowel 1, improve machining accuracy.
Illustrate that the utility model specific embodiment is as follows in conjunction with the embodiments：
As shown in Fig. 2 the utility model and workpiece to be processed are clamped to vertical knee-type milling machine machine folder.
The axis of the locating dowel 1 is set to be overlapped with the midpoint of the semicircle orifice 9.
Load the milling cutter 4 in the cutter holder 3.
The gear of the pitch adjusting structure 5 is adjusted, is slided in the transverse arm 2 by cutter holder described in rack drives 3, made described
The outer rim of milling cutter 4 is fitted with the inner side of the curved profile of the semicircle orifice 9.The stop screw 31 is screwed, stablizes determining for the milling cutter 4
Position.
While the milling machine head drive milling cutter 4 carries out milling, the transverse arm 2 is driven to be revolved around the axis of the locating dowel 1
Turn special angle (angle is drawn by the radius calculation of the milling cutter 4 and the semicircle orifice 9), complete the outermost layer of semicircle orifice 9
The processing of camber line profile.
After unscrewing the stop screw 31, adjusting the pitch adjusting structure 5 makes the cutter holder 3 drive the milling cutter 4 to described
The direction movement (displacement is less than the diameter of the milling cutter 4) of locating dowel 1, after screwing the stop screw 31, milling machine head band
The dynamic transverse arm 2 is reversely rotated, the sector region of semicircle orifice 9 described in the milling of the milling cutter 4.Repeat the above steps, until the milling
Knife 4 completes the Milling Process of the whole sector regions of the semicircle orifice 4.
It is artificial to substitute using the automatic regulation device of above-mentioned pitch adjusting structure 5 as improvement project of the present utility model
Roll adjustment and fixation, make the utility model realize automation Milling Process, to improve processing efficiency.
