The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Principle of the present utility model is: be provided with a fixing boring cutter bar, specifically one end of boring cutter bar be fixed on the chuck of lathe one end, the other end is fixed on the boring cutter bar slide of the lathe other end; Boring cutter bar is provided with can make along boring cutter bar the cutterhead of traveling priority, and, boring cutter bar is provided with screw mandrel, on cutterhead, be fixed with screw, by driven by motor screw mandrel, just can allow cutterhead do feed campaign at the uniform velocity, because boring cutter bar is fixed, so the track of cutterhead feed is straight line, guaranteed the precision of bore hole.
Embodiment:
As shown in Figure 1, a kind of lathe of processing high speed roller endoporus, comprises headstock and lathe bed; Headstock comprises main shaft 1 and is arranged on the chuck 2 on main shaft, and chuck 2 end faces are provided with one or more bearings 21, the dead in line of the axis of bearing 21 and main shaft 1, and bearing 21 is provided with columniform boring cutter bar 3; Lathe bed one end is chuck-end, and one end is tailstock end, and tailstock end is provided with boring cutter bar slide 4; Lathe bed is provided with the roller frame 5 of a plurality of supporting workpieces at chuck-end and tailstock end, roller frame is provided with the support roller that can rotate; Boring cutter bar slide 4 is provided with the slide rail coordinating with boring cutter bar 3 and pushes down the pressing plate (slide rail and pressing plate do not illustrate in the drawings) of boring cutter bar; Boring cutter bar 3 one end are fixed in the endoporus of bearing 21, and the other end is fixed in the slide rail of boring cutter bar slide 4; Boring cutter bar 3 is arranged with and can along boring cutter bar 3, makees the cutterhead 31 of traveling priority, and the external diameter of cutterhead 31 is less than the endoporus of high speed roller 8; Boring cutter bar 3 is provided with the screw mandrel that at least surpasses boring cutter bar 3 half length, and cutterhead is provided with the screw (screw mandrel and screw do not illustrate in the drawings) that can coordinate with screw mandrel.
The step that specifically adds man-hour:
A. workpiece (high speed roller 8) one end is by clamping chuck driving, and the other end is placed on roller frame 5, the locking of center centering.
B. lock boring cutter bar slide 4, boring cutter bar 3 moves and stretches into chuck hub along boring cutter bar slide 4, arrives assigned address (coordinating with bearing 21) locking boring cutter bar 3.
C. start lathe, workpiece rotates, and cutterhead 31 vertically moves along boring cutter bar, and the boring cutter on cutterhead 31 cuts high speed roller 8 endoporus.Because boring cutter bar 3 is to be contained on the bearing of chuck, add on boring cutter bar slide 4 and have pressing plate that boring cutter bar 3 is pushed down.So when chuck rotates, boring cutter bar 3 does not rotate,
Lathe in the present embodiment and general lathe are somewhat similar, but lathe bed is very long, are mainly that high speed roller 8 is long.
The bearing 21 of chuck end face has several effects, and one is location, because the dead in line of the axis of bearing and main shaft, so boring cutter bar 3 installs on bearing, has guaranteed the position of boring cutter bar 3.Second is can allow boring cutter bar 3 not follow chuck rotate together, because when chuck rotates, the outer ring of bearing (if plane bearing, DNA releaxed circular DNA) can rotate, the 3rd is to bear certain cutting counter-force, boring cutter is in working angles, can bear the counter-force of workpiece, these counter-forces also can be applied to boring cutter bar 3, and bearing just can cushion these power, avoid the impact on chuck.
These counter-forces, existing power radially, also has axial power, so bearing preferably by can bearing radial force and the combining of axial force, the bearing of bearing radial force and axial force also has simultaneously, but bear limited in one's ability.
Boring cutter bar slide 4 is provided with the slide rail coordinating with boring cutter bar 3 and pushes down the pressing plate of boring cutter bar, slide rail is used for supporting boring cutter bar and allows boring cutter bar move by slide rail, stretch in the brearing bore on chuck, pressing plate arrives after assigned address at boring cutter bar, just boring cutter bar is pushed down, do not allowed boring cutter bar have the possibility of upper and lower play.
Certainly, the main shaft in the present embodiment, and general lathe is similar, and it drives by motor, and gearbox is generally also established in centre, and these have no longer described in detail.
Boring cutter bar 3 is provided with the screw mandrel that at least surpasses half length of boring cutter bar, and cutterhead is provided with the screw that can coordinate with screw mandrel.Surpass half length, just can pass through twice clamping, complete processing.Certainly preferably the same with boring cutter bar long, so just can complete processing by clamped one time.
Screw mandrel is very little, both can directly be contained in boring cutter bar 3 outsides, also can half be contained in boring cutter bar the inside, half outside, or other mode, as long as can feed, this be that those skilled in the art can understand.
In the present embodiment, chuck end face is provided with a radial ball bearing and a plane bearing, and the tight ring of plane bearing is against the shaft shoulder of boring cutter bar.Namely press the direction of Fig. 1, radial ball bearing on the left side, plane bearing is on the right.
In the present embodiment, chuck seat is provided with the claw of a plurality of clamping high speed rollers.Can be according to circumstances, the claw of varying number is installed, generally at least three, many also with regard to 8, this is that those skilled in the art can understand.
In the present embodiment, slide rail is a kind of rectangular guideway.Processing is fairly simple like this, also meets instructions for use (can moving at rectangle cathetus of cylinder).
In the present embodiment, cutterhead is provided with the installation position of a plurality of installation boring cutters.Dissimilar boring cutter can be according to circumstances installed.
In the present embodiment, screw mandrel drives by lead screw motor 6, is also provided with reduction box 7 between lead screw motor and screw mandrel.Spindle motor can be general alternating current generator, can be also buncher or direct current generator etc., and reduction box is general primary speed-down transmission.
In the above-described embodiments, a kind of lathe of processing high speed roller endoporus that the utility model provides, be provided with a fixing boring cutter bar, specifically one end of boring cutter bar be fixed on the chuck of lathe one end, the other end is fixed on the boring cutter bar slide of the lathe other end; Boring cutter bar is provided with can make along boring cutter bar the cutterhead of traveling priority, and, boring cutter bar is provided with screw mandrel, on cutterhead, be fixed with screw, by driven by motor screw mandrel, just can allow cutterhead do feed campaign at the uniform velocity, because boring cutter bar is fixed, so the track of cutterhead feed is straight line, guaranteed the precision of bore hole.Its beneficial effect is: first guaranteed position and the form accuracy of endoporus, secondly dimensional accuracy and surface roughness are also guaranteed.
Above-described is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
