Abstract
The utility model relates to a wood cutter specifically is a padauk blind hole jacking cutting off tool. It is main including bearing, cutter arbor, circular arc saw bit, deflector, ratchet, pawl, hand wheel. Its characterized in that: the cutter arbor front end is equipped with the circular arc saw bit, and fillet arc shape is made to the circular arc saw bit, makes the plane and the cutter spindle line of circular arc saw bit install perpendicularly, solves the bottom surface and cuts off the problem, the bearing left end of cutter arbor is fixed with the deflector, plays direction, supporting, firm and cushioning effect, the material core problem of taking out behind the solution jacking, the ratchet detent mechanism is installed to the cutter arbor stalk portion, forms one -way intermittent movement, prevents that the sawing from assaulting, guarantees to cut off steady reliably.
Description
Technical field
The utility model is a kind of wood cutter, is specially a kind of narra non-penetrated hole jacking cutting off tool.
Background technology
From ancient times to the present, narra always is not only rare but also expensive timber.Often utilize its craft articles to collect, as when making the handicrafts such as pen container, needing to draw out heart portion material, generally adopting jacking cutting tool, the material core drawn out can continue to use, and saves raw material, reduces cost.But after non-penetrated hole jacking, how material core cuts off taking-up, is a difficult problem.Material core interrupts by conventional method wedge tool, then will expect that core takes out.This mode needs jacking gap large, and material core is easily destroyed, simultaneously working (machining) efficiency and utilization rate low.
Summary of the invention
Taking-up problem is cut off after solving narra non-penetrated hole jacking, the utility model provides a kind of non-penetrated hole jacking cutting off tool, this cutter is effective cut-out work after can completing jacking, realize the parallel cut-out of material core root section, after cutting off, blind hole bottom surface is very smooth with material core section, use result to show that this unit efficiency is high, stable performance, reliable, the cross-sectional face quality processed is higher.
The utility model solves the technical scheme that its technical problem adopts: a kind of carpenter's non-penetrated hole jacking cutting off tool, comprises supporting base, knife bar, circular saw disk, guide plate, ratchet, ratchet, handwheel.It is characterized in that: tool bearing seat is contained on general horizontal lathe squaring head, supporting base left end is fixed with guide plate, supporting base and guide plate have a coaxial through hole, and knife bar is through through hole, and knife bar front end is provided with circular saw disk, circular saw disk makes fillet circular shape, circular saw disk thickness is 2 ~ 3cm, and circular saw disk width is 8 ~ 12cm, and the anterior angle of circular saw disk sawtooth is 16 ° 18 ', relief angle is 18 ° 42 ', and the angle of wedge is 55 °.Make plane and the knife bar axis at right angle setting of circular saw disk, knife bar shank is provided with ratchet and pawl arrangement.During cut-out, first allow the counterclockwise continuous rotation of processed round log, control cutter by hand feed case and enter into the degree of depth needing to cut off, then handwheel is rotated clockwise, circular saw disk is driven to rotate by knife bar, make circular saw disk and round log produce the motion of relative sawing, will expect that core cuts off along circular saw disk plane orthogonal material wire mandrel.
The beneficial effects of the utility model are: expect after effectively solving narra jacking that core cuts off and take out a difficult problem, circular saw disk and round log is made to produce the motion of relative sawing, coordinate click intermittent motion mechanism, safe and efficient, reliable and stablely can cut out the higher surface of quality, and structure is simple, facilitates handy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is left view of the present utility model.
In figure: 1. circular saw disk, 2. trip bolt, 3. knife bar, 4. guide plate, 5. supporting base, 6. gusset, 7. ratchet, 8. handwheel, 9. ratchet.
Detailed description of the invention
In FIG, by supporting base (5) retained part clamping in some cutter spacing of horizontal lathe squaring head, adjust the center line of knife bar (3) and lathe spindle center line in the same horizontal line by pad, rotate handwheel and regulate circular saw disk (1) to overlap with guide plate (4) end face circular arc.When sawing, guide plate (4) plays a part to support circular saw disk, prevents from causing circular saw disk to shake and distortion by cutting-impact power, ensures to cut blind hole bottom surface smooth.Rotate the handwheel on lathe carriage and the handle on cross slide, allow guide plate slowly enter the arc groove of expecting between core and shell, after arrival bottom land, stop the operation of slip crate, keep slip crate motionless.Now, adjustment lathe rotating speed, start lathe spindle, scroll chuck is made to drive processed narra to be rotated counterclockwise, then the adjusting handle (8) on knife bar (3) is slowly rotated clockwise, handwheel (8) drives knife bar (3), and knife bar (3) drives circular saw disk (1) to turn clockwise, and material core can entirely be sawed down by the relative motion producing circumferencial direction between circular saw disk (1) and material core.In addition, knife bar (3) axle is installed ratchet (9), gusset (6) has been installed ratchet (7), has realized click gear motion, easily can realize handwheel (8) interval steadily to rotate, prevent from cutting the phenomenons such as sawing impact simultaneously.Can also, by the oilhole charging-up lubricant oil on supporting base, knife bar be lubricated fully.
